Abstract From the perspective of perturbation theory, we propose a systematic procedure for the evaluation of the derivative discontinuity

(DD) of the exchange-correlation energy functional in Kohn-Sham density functional theory (KS-DFT), wherein the exact DD can

in principle be obtained by summing up all the perturbation corrections to infinite order [1]. Truncation of the perturbation series at

low order yields an efficient scheme for obtaining the approximate DD. While the zeroth-order theory yields a vanishing DD, the

first-order correction to the DD can be expressed as an explicit universal functional of the ground-state density and the KS lowest

unoccupied molecular orbital density, allowing the direct evaluation of the DD in the standard KS method without extra

computational cost. The fundamental gap can be predicted by adding the estimated DD to the KS gap. This scheme is shown to be

accurate in the prediction of the fundamental gaps for a wide variety of atoms and molecules.


Invited Speech: Manipulation of Proteins in Lipid Bilayer Arrays Using an

Speaker: Prof. Xiaojun Han, Harbin Institute of Technology, China Time: 09:10-09:50, September 19, 2013 Location: ORCHID ROOM (雅兰厅) 2nd

Abstract


It is estimated that about 30% of the proteins encoded in the human genome are membrane proteins and that they represent the

main target of nearly 50% of known drugs. In most cases these proteins lose their structure and functions, when removed from their

membranous environment. Thus there is significant interest in creating artificial mimics of phospholipid membranes on solid

supports with the aim of producing a platform for separating membrane proteins and studying their structure and functions in situ.

We developed a method to fabricate lipid bilayer arrays using UV photo patterned self assembled monolayers (SAMs) and

polyelectrolyte multilayers. Depending on the molecular structure, soft UV light (365 nm) or deep UV light (254 nm) was chosen

to make patterned surfaces. The lipid bilayer arrays were used to separate charged lipids or proteins by electrophoresis. Either


oppositely charged fluorescent labeled lipids [Texas red DHPE (one negative charge) and D291 (one positive charge)] or lipids

with different charge number [Texas red DHPE (one negative charge) and NBD PS (two negative charges)] can be separated. We

have also studied the migration of streptavidin attached to a biotinylated lipid. After demonstrating the usefulness of lipid bilayer

arrays on manipulation of charged lipids and membrane attached protein under DC electric fields, a true membrane protein (Cym A)

was concentrated using a trap shape patterned lipid bilayer under AC electric fields. Conventional supported lipid bilayer

membrane is not suitable for transmembrane protein reconstitution due to the narrow space between the membrane and substrate.

Therefore lipid bilayer membrane arrays, which are far away from the substrate, are endeavoured to be fabricated.

Invited Speech: From Biophysics to Cancer Treament: New Opportunities

Using Cell Electroporation Technology for Improving Cancer

Radiotherapy

Speaker: Prof. Kaushala Prasad Mishra, Nehru Gram Bharati University, India Time: 09:50-10:30, September 19, 2013 Location: ORCHID ROOM (雅兰厅) 2nd Floor, Beijing Yanshan Hotel Abstract Exposure of living cells to high intensity but brief electrical pulses ( a few kV/cm, ms duration ) has become an active area of

biophysical research and cell biotechnology applications in the recent years. Plasma membrane of cells become transiently

permeable on application of external electric field above a characteristic threshold value permitting exchange of molecules between

cell interior and the surrounding. This phenomenon, popularly called electroporation, has opened many new possibilities of bacteria,

plant and mammalian cell manipulation. For example, electroporation allows gaining direct access into the cell cytoplasm, to

transfer gene into a variety of cells giving efficient transformation and to achieve cell fusion for hybridoma technology. In our

laboratory extensive studies have been carried out on electroporation of red blood cells that have provided useful data with regard

to nature, lifetime and resealing properties of electroporated cells in isotonic solutions. Understanding of molecular mechanism of

electro-permeabilization of cell is rapidly accumulating. Potential of drug loaded red cells for achieving effective cancer treatment

by targeted delivery of drugs appears promising. In addition, our in vitro studies on Ehrlich ascites cells have shown that at non-

toxic concentrations of doxorubicin, an antitumor drug, produced substantial cytotoxic effects when drug treated cells were

subjected to electroporation presumably due to enhanced intracellular incorporation of the drug. These results have deeper

implications in designing a strategy to overcome tumor drug resistance by employing electroporation technology. More recently,

results from our laboratory have shown that tumor cells can be sensitized to γ irradiation effects when combined with

electroporation indicating a possibility of overcoming the problem of radioresistance. A highlight of the developing new

approaches based on membrane permeabilization will be presented with examples to newer protocol for effective cancer treatment

in clinics.

ID: 40020 Title: Incoherent Oscillations a ccompanying Charge Separation in Photosynthetic Reaction Centers Name: Yakovlev Andrei Affiliation: Moscow State University E-mail: [email protected] ABSTRACT Early events of charge separation in reaction centers (RCs) of bacterial photosynthesis are modeled by kinetic equations with time-dependent rate constants. An illustrative case of regular motion along a “slow” coordinates leading to oscilla-tions in the kinetics is examined. Different schemes of charge separation are investigated. A good fitting of experimen-tal kinetics of native Rba. sphaeroides RCs is achieved in the five states model P*1BAHA ↔ P*2BAHA ↔ I ↔ P+BA–HA & P+BAHA– with two excited states P*1BAHA and P*2BAHA and three charge separated states I, P+BA–HA and P+BAHA– (P is a primary electron donor, bacteriochlorophyll dimer, BA and HA are an electron acceptors, monomeric bacterio-chlorophyll and bacteriopheophytin in active A-branch, respectively). In the model only the first excited state is directly populated by optical excitation. The emission of the two excited states is assumed to be at 905 and 940 nm, respec-tively. The intermediate state I is assumed to absorb at 1020 nm as well as the P+BA–HA state. The model explains the deep oscillations in the kinetics of the P*1,2 stimulated emission and of the BA– absorption. In the simpler schemes without the I state or with only one excited state the accordance with the experiment is achieved at unreal parameter values. A possible nature of the I and P*2BAHA states and a possible incoherent nature of the oscillations are discussed.


ID: 40046 Title: Beta Amyloid Interaction with Plasma Membrane “Raft Constituent” as Probed by Dual-Channel Paired Surface Plasmon Wave Detection Name: Wei-Ju Chen Affiliation: Chang Gung University E-mail: [email protected] ABSTRACT Alzheimer’s Disease (AD) is a progressive, neurodegenerative disease affecting millions worldwide that currently is without cure. Researchers have increasingly focused on the importance of the beta-amyloid (Aβ) oligomer as this extracellular protein enters neuronal cells and subsequently causes cellular toxicity. Our hypothesis is that a key plasma membrane constituent, the detergent-resistant membrane construct called “lipid raft” plays an important role in controlling Aβ oligomers’ docking and subsequently assembling and disrupting the membrane structure, thus providing access for toxic species of Aβ to enter the cell. Our platform is a supported-lipid-bilayer construct that mimics the raft structure. Using ultrasensitive, dual-channel paired surface plasmon wave detection method (Su, Chang et al. 2012) capable of detecting ~pM protein concentration, we detected changes in lipid structures upon their interaction with the introduction of Aβ monomers and oligomers at physiological concentrations (nM).

Analytical Chemistry 84(9): 3914-3920. ID: 40103 Title: Binding-Coupled Domain Oligomerization: Structural and Functional Insights into BS69 Name: Jikui Song Affiliation: University of California E-mail: [email protected] ABSTRACT Eukaryotic gene transcription is tightly regulated by an intricate network of protein-protein interactions, which often involves substantial changes of chromatin structure. A number of transcription corepressors, such as BS69, play an important role in mediating gene expression through formation of gene silencing complexes. However, their molecular mechanisms remain poorly understood. To illustrate how BS69 interacts with other cellular or viral proteins, we have investigated the structure of the BS69 MYND domain bound to a peptide derived from the oncogenic protein EBNA2. The structure reveals that the EBNA2 peptide binds to the BS69 MYND domain in a stoichiometry of one to two. Such an interaction mode is distinct from what previously observed for other MYND domains, and suggests that the BS69 MYND domain-mediated protein interaction potentially help dimerize two BS69 molecules. Our biochemical analysis further indicates that such binding-coupled domain oligomerization is facilitated by the preceding coiled-coil domain in BS69. Together, our study established that the oligomerization state of BS69 is enhanced by its MYND domain-mediated interaction with EBNA2. The functional implication of this binding-coupled domain oligomerization will be discussed. ID: 40128 Title: Increasing Protein Stability with Simulated Honey Sugar Cocktail Name: Saad Tayyab Affiliation: University of Malaya


E-mail: [email protected]

ABSTRACT Increasing protein stability is an important subject for both basic and applied researches. Honey may act as a protein stabilizer due to the presence of high sugar content in it. The protein stabilizing potential of honey was elucidated using simulated honey sugar cocktail (SHSC) on three model proteins, namely, serum albumin, ovalbumin and lysozyme against chemical and thermal denaturations. Urea-, GdnHCl- and thermal-induced transition curves of these proteins were shifted towards higher denaturant concentrations or temperature in the presence of different SHSC concentrations (8–30%, w/v), when studied by far-UV CD, intrinsic fluorescence and UV difference absorption spectroscopy as well as differential scanning calorimetry. The shift in the denaturation transition curves was found to be concentration dependent, being more pronounced in the presence of higher SHSC concentration. The stabilizing potential of SHSC was further evaluated by equilibrating the partially-denatured protein (at the mid-point of the transition) with SHSC and studying the structural changes by far- and near-UV CD spectra, UV difference spectra, tryptophan fluorescence and three-dimensional fluorescence spectroscopy as well as ANS binding. These results suggested significant retention of the globular conformation of partially-denatured protein in the presence of SHSC. Taken together, all these results suggested significant stabilization of native protein conformation in the presence of SHSC against chemical and thermal denaturations. ID: 40130 Title: Monitoring Structural Integrity in Biotherapeutic Development Using SPR, DSC and 2D-DIGE Name: Ewa Pol Affiliation: GE Healthcare Bio-Sciences E-mail: [email protected] ABSTRACT The three dimensional conformation of biotherapeutic drugs is an important factor for the biological function and has an impact on safety and efficacy. To ensure 3D structural similarity and comparability of these complex molecules, analysis of important quality attributes throughout the entire development process as well as of the final product is essential. Here we report on an approach to antibody testing, in which the structural integrity of humanized monoclonal antibody of IgG1 class was examined by analyzing the binding characteristics of the interaction with structure-sensitive reagents. We selected a panel of molecules covering the constant domains of IgG1 and analyzed their binding to the wild-type and several stressed variants of an antibody, using a Surface Plasmon Resonance (SPR) assay. We were able to detect significant differences in binding patterns between the wild-type and the stressed variants, which could be connected to the stress-induced modifications at molecular level. A correlation was found between the results from the binding assay and Differential Scanning Calorimetry (DSC) data. In addition, the properties of biotherapeutic variant, such as molecular weight and isoelectric point, were revealed by Two-Dimensional Difference Gel Electrophoresis (2D-DIGE). The presented method might be an interesting tool for monitoring structural integrity of therapeutic antibodies during up and downstream processing. ID: 04120 Title: Nitrile-synthetic enzyme: Structure and characterization Name: Michihiko Kobayashi Affiliation: University of Tsukuba ABSTRACT


The microbial degradation of nitriles proceeds through two enzymatic pathways: nitrile hydratase (NHase) catalyzes hydration of nitrile to amide, whereas nitrilase catalyzes hydrolysis of nitrile to acid and ammonium. The industrial Pseudomonas chlororaphis B23 strain is able to grow on the medium containing nitrile as the sole carbon and nitrogen sources. We clarified the NHase gene cluster, which consists of seven genes (i.e. oxdA, amiA, nhpA, nhpB, nhpC, nhpS and acsA); e,g, OxdA is aldoxime dehydratase; AmiA is amidase; NhpA is NHase alpha-subunit; NhpB is NHase beta-subunit; AcsA is acyl-CoA synthetase)[1-3]. Particularly, OxdA is very unique and intriguing in the following aspects. This enzyme is a new hemoprotein that catalyzes the synthesis of nitrile with a highly toxic functional group (carbon-nitrogen triple bond). OxdA catalyzes dehydration of aldoxime to nitrile even in the presence of water in the reaction mixture. Unlike the utilization of H2O2 or O2 as a mediator of catalysis by other heme-containing enzymes (e.g., P450), OxdA is notable for the direct binding of a substrate to the heme iron [4,5]. Therefore, the reaction mechanism of this enzyme would be attractive. This enzyme is not only academically interesting, but is also expected to be applicable to the practical production of nitriles, because the enzyme reaction occurs under mild conditions, in contrast to the chemical dehydration of aldoximes under harsh conditions. We here determined the crystal structure of OxdA [6]. We next constructed mutant enzymes, in which each of the amino acids lying around the iron atom of the heme was converted to alanine by site-directed mutagenesis. Among the purified mutant enzymes, S219A had completely lost and R178A exhibited a reduction in the activity. Together with this finding, the structural analysis of OxdA and spectroscopic analyses of the wild-type and mutant enzymes indicate that S219 plays a essential role in the catalysis, forming a hydrogen bond with the substrate. Based on the spatial arrangement of the OxdA active site and the results of a series of mutagenesis experiments, we have succeeded in clarifying the reaction mechanism of aldoxime dehydratase. ID: 40169 Title: Least Action Trajectory in Neural Networks Name: Bhazel Anne Pelicano Affiliation: University of the Philippines Baguio E-mail: [email protected] ABSTRACT The study of complex networks had developed over the years to include systems such as traffic, predator-prey interactions, financial market, and even the world wide web. Complex network studies encompasses biology, chemistry, physics, and even engineering and economics. However, the dynamics of such complex networks are yet to be understood fully. In this paper, we will be focusing mostly on the possible learning ability in a complex network. To do this, an optimization process is used via Wiener process. It is apparent from the sample lattice shown that the final position was not a basis of the transition probability, or it was never used to calculate the probability, since the transition probability only considers the current position. The final point is reached because of the orientation of the edges, where each edge is facing the final point, an aspect of the nervous system (afferent and efferent nerves). No matter how random the orientation of the neurons, each directs to the central nervous system for processing and is transmitted away for reaction.

ID: 40023 Title: Capacity Worth of Energy Storage System in Renewable Power Generation Plant Name: Li Jinbin Affiliation: Hubei Electric Power Research Institute E-mail: [email protected] ABSTRACT With the advance in renewable generation technologies, the cost of renewable energy becomes increasingly competitive when compared to fossil fuel-based generation resources. It is economically beneficial to integrate large amounts of renewable capacity in power systems. Unlike traditional generation facilities, however, using renewable resources for generation presents technical challenges in producing continuous power. In this report, an Energy Storage System (ESS) is integrated to smooth the variations in renewable power production and ensure the output power more controllable. Since it requires capital investment for the storage devices, it is important to obtain reasonable estimate of the storage capacities. This project is therefore formulated as an optimization problem in determining the two dominating factors of the capital cost for the ESS: the power capacity and the energy capacity. The objective is to make the renewable power more reliable and simultaneously maximize the economic benefits that can be obtained from the scheme. To make the results more convincing, analyses in this report starts with wind generation, for wind has greater variability and unpredictability than other renewable sources. Selection of ESS type is narrowed down to battery energy storage system (BESS) in the scheme. However, the methods presented here are


suitable for any type of energy storage methods and are also useful for intermittent renewable energy resources other than wind. ID: 40084 Title: A Method for Assessing Customer Harmonic Emission Level Based on the Iterative Algorithm for Least Square Estimation Name: Fan Run-rong Affiliation: Wuhan University E-mail: [email protected] ABSTRACT With the power system harmonic pollution problems become more serious, how to distinguish the harmonic responsibility accurately, solute the grid harmonics simply and effectively, has become the main development direction in harmonic control subjects. This paper based on linear regression analysis of basic equation and improvement equation. Deduced the least squares estimation (LSE) iterative algorithm and obtained the real-time estimates of regression coefficients, and then calculated the level of the harmonic impedance and emission estimates in real time. This paper use power system simulation software Matlab / Simulink as analysis tool, analyzed the user side of the harmonic amplitude and phase fluctuations PCC (point of common coupling) at the harmonic emission level, the research has a certain theoretical significance. The development of this algorithm combined with the instrument can be used in practical engineering. ID: 40086 Title: Maintenance Scheduling of Distribution System with Optimal Economy and Reliability Name: Hong Siyuan Affiliation: South China University of Technology E-mail: [email protected] ABSTRACT With the continuous expansion of power grid, the number of power equipments has become larger and larger. In order to make sure that all the equipments can operate reliably, a large amount of maintenance tasks should be conducted. Therefore, maintenance scheduling of distribution network is an important content, which not only has significant influence on reliability and economy of distribution network operation, but also is related to the vital interests of grid department and users. This paper proposes a new model for maintenance scheduling which considers load loss, grid active power loss and system risk as objective functions. On this basis, adopt Differential Evolution algorithm to optimize equipment maintenance time and load transfer path. Finally, the general distribution network of 33 nodes is taken for example which shows the maintenance scheduling model’s effectiveness and validity. ID: 40088 Title: Analysis of Switching Overvoltage in Regional Grid with Small Hydropower Plants Name: Chen Juan Affiliation: South China Univ. of Technology E-mail: [email protected] ABSTRACT


Present-day small hydropower plants (SHPs) have a large development potential because of the increasing interest in renewable resources and distributed energy generation, therefore, there are many SHPs in places of China where is rich in water resources. However, it has caused overvoltages in the distribution network, and which is even more worse for the switching overvoltage such as isolated network operation, changing power supply path. The simple network model is used to analyze the reasons of the switching overvoltage, and the simulation software DIgSILENT/PowerFactory is used to check out the results of the theoretical analysis. ID: 40105 Title: Load Cluster Characteristic Analysis and Modeling of Electric Vehicles Name: Zeng Dan Affiliation: China Electric Power Research Institute E-mail: [email protected] ABSTRACT Electric vehicle as a clean energy industry is an important branch. Electric vehicles not only are the energy of the elec-tric user, but also can be used as mobile, distributed energy storage unit to the grid. As a precondition of safety opera-tion for power grid, studies of EVs’ charging load characteristics is also the theoretical basis of intelligent scheduling EVs charging orderly. This paper assesses the future the development prospects electric vehicles, and secondly establishes a charging model of a single EV. Then, considering stochastic distribution of the initial state-of-charge (SOC0) and the arriving time of the vehicles, a cluster model of the charging station is proposed. Meanwhile, the paper from the types and charging mode of electric vehicles analyzes the behavior of EV. Finally, an example simulation is validated. ID: 40137 Title: The Reliability Evaluation Method Study of Power System Communication Networks in Case of Ice Storm Name: Yang Jianghua Affiliation: Sichuan University E-mail: [email protected] ABSTRACT This paper is divided into two cases to study the communication transmission equipment reliability in the state of the ice storm, according to the huge losses of power system communication caused by the ice storm. For the nodes or links which are not affected by the ice storm, using the calculation with ‘the mean time between failures(MTBF)’ and ‘the mean time to repair’(MTTR) to put forward the calculation methods; for the OPGW cable which influenced greater in ice storm, using the fiber excess length and the elongation of fiber optic cable. It obtains all the paths of the network through improved adjacency matrix method, and then it uses binary decision diagram to obtain the overall reliability of the network. Test the network nodes and links using “N-1” inspection, the key nodes and key links can be obtained; finally, considering the importance degree of network transmission business, the reliability evaluation method of power system communication network based on the risk theory in the case of the ice storm has been put forward, and example to verify that the method can provide the basis for the reliability assessment of the power system communication in the case of the ice storm.

Title: High-Impedance Bus Differential Protection Modeling in ATP/MODELS Name: Alvarenga Mardennia Tarsis Silva Affiliation: University of Brasilia E-mail: [email protected] ABSTRACT This paper presents a modeling of a high-impedance bus differential protection logic using the ATP (Alternative Transients Program) MODELS language. The model is validated using ATP simulations on an electrical system consisting of a sectionalized bus arrangement with four transmission lines (TLs) and two autotransformers. The obtained results validate the model and present some of the advantages of using this type of bus protection, such as fast and safe operation, even when under adverse conditions such as current transformers (CTs) magnetic core saturation upon the occurrence of external faults. ID: 40173 Title: PI-MPC Frequency Control of Power System in the Presence of DFIG Wind Turbines Name: Bernard Michael Affiliation: Kyushu Institute of Technology E-mail: [email protected] ABSTRACT For the recent expansion of renewable energy applications, Wind Energy System (WES) is receiving much interest all over the world. However, area load change and abnormal conditions lead to mismatches in frequency and scheduled power interchanges between areas. These mismatches have to be corrected by the LFC system. This paper therefore, proposes a new robust frequency control technique involving the combination of conventional Proportional-Integral (PI) and Model Predictive Control (MPC) controllers in the presence of wind turbines (WT). The PI-MPC technique has been designed such that the effect of the uncertainty due to governor and turbine parameters variation and load disturbance is reduced. A frequency response dynamic model of a single-area power system with an aggregated generator unit is introduced, and physical constraints of the governors and turbines are considered. The proposed technique is tested on the single-area power system, for enhancement of the network frequency quality. The validity of the proposed method is evaluated by computer simulation analyses using Matlab Simulink. The results show that, with the proposed PI-MPC combination technique, the overall closed loop system performance demonstrated robustness regardless of the presence of uncertainties due to variations of the parameters of governors and turbines, and loads disturbances. A performance comparison between the proposed control scheme, the classical PI control scheme and the MPC is carried out confirming the superiority of the proposed technique in presence of doubly fed induction generator (DFIG) WT. ID: 40176 Title: Analysis of Cooperation between Wind Power and Load Side Resources Name: Xiao-rui Guo Affiliation: China Electric Power Research Institute E-mail: [email protected]

ABSTRACT Development of the intermittent energy is greatly promoted by change in energy, while consumption of large-scale intermittent energy is becoming a problem. With the development of smart grid technology, controllability of load


side resources is more important. Based on the wave characteristics of wind power, this paper indicates that wind energy have continuous output characteristics on the hour-time scale. Through analysis on loads characteristic of industry, public facility and resident, this paper gets comprehensive response of load side resources. Considering characteristics of wind power output, combined with different load side resources and DR program, this paper suggests cooperation between wind power and load side resources on different time scales.

Speaker: Prof. Wei-Chang Yeh, National Tsing Hua University, Chinese Taipei Time: 08:30-09:10, September 21, 2013 Location: ORCHID ROOM (雅兰厅) 2nd Floor, Beijing Yanshan Hotel Abstract In the traditional flow network reliability problem, it is assumed that the flow is fixed in each arc. However, the flow may

experience gain after transmission via arcs because of the learning effect in many real-life networks. Hence, a novel network model

called the arc-based learning-effect multi-state flow network (ALMFN) is proposed to meet the real world problem. A

straightforward and simple algorithm based on minimal path (MP) set is presented here to evaluate ALMFN reliability,which is

defined as the probability that dunits of data can be sent from the source node to the sink node through the ALMFN. The

computational complexity of the proposed algorithm is also analyzed. Finally, an example is given to illustrate how the ALMFN

reliability is calculated using the proposed algorithm.

Two different types of natural fibers reinforced plastics (NFRP) laminate were incorporated into the new sandwich panel as an intermediate layer. The significance analysis in this research has been carried out using analysis of variance (ANOVA). As the aim of the analysis is to select the most appropriate natu-ral fiber composites for the intermediate layer, the experiments were arranged as a single factor experiment in which 3 levels of a factor have been examined. The factor refers to the type of intermediate layer used in the sandwich panel. The result of this study shows that the incorporation of intermediate layer has significantly enhanced the load carrying capacity of the sandwich panels. ID: 40074 Title: Intrinsic Compression Behavior of Remolded and Reconstituted Clays-Reappraisal Name: Jie Yin Affiliation: Jiangsu University E-mail: [email protected] ABSTRACT Evaluating the impacts of soil structure on mechanical behavior for natural sedimentary clays is an important issue in geotechnical engineering. Burland introduced void index for normalizing the compression curves of various remolded and reconstituted clays to obtain the intrinsic compression line, which provides a reference framework to assess the in-situ compression behavior. However, it does not quantitatively account for the effects of initial water content on compressive behavior of remolded and reconstituted clays and the initial water contents of clays are not always limited to 1.0~1.5 times the liquid limits defined by Burland. A modification based on collected tests data was presented on the expressions of e*100 and C*c defined by Burland. Extensive oedometer test data were also collected on various remolded and reconstituted soils with distinct liquid limits and initial water contents to verify the validity of modified expressions. A normalized compression line deduced by intrinsic compression line is proposed in the e-log p plot, which can be used to evaluate the effects of soil structure quantitatively on the intact compressive behavior for natural sedimentary clays. ID: 40133 Title: 3-D Modelling of the Confederation Bridge Using Data of Full Scale Tests Name: Lin Lan Affiliation: Concordia University E-mail: [email protected] ABSTRACT Long-span bridges are special structures that require advanced analysis techniques to examine their performance. This paper presents a procedure developed to model the Confederation Bridge using 3-D beam elements. The model was


validated using the data collected before the opening of the bridge to the public. The bridge was instrumented to con-duct full-scale static and dynamic tests. The static tests were to measure the deflection of the bridge pier while the dy-namic tests to measure the free vibrations of the pier due to a sudden release of the static load. Confederation Bridge is one of the longest reinforced concrete bridges in the world. It connects the province of Prince Edward Island and the province of New Brunswick in Canada. Due to its strategic location and vital role as a transportation link between these two provinces, it was designed using higher safety factors than those for typical highway bridges. After validating the present numerical model, a procedure was developed to evaluate the performance of similar bridges subjected to traffic and seismic loads. It is of interest to note that the foundation stiffness and the modulus of elasticity of the concrete have significant effects on the structural responses of the Confederation Bridge. ID: 40168 Title: Experimental Behavior of Partially Prestressed High Strength Concrete Beams Name: Shady Salem Affiliation: The British University in Egypt E-mail: [email protected] ABSTRACT In the last few decades, prestressed concrete has been rapidly used in bridge engineering due to the enormous development in the construction techniques and the increasing need for long span bridges. High strength concrete has been also more widely spread than the past. It currently becomes more desirable as it has better mechanical properties and durability performance. Major defect of fully prestressed concrete is its low ductility; it may produce less alarming signs than ordinary reinforced concrete via smaller deflection and limited cracking. Therefore, partially prestressing is considered an intermediate design between the two extremes. So, combining high strength concrete with partial prestressing will result in a considerable development in the use of prestressed concrete structures regarding the economical and durability view points. This study presents the results of seven partially prestressed high strength concrete beams in flexure. The tested beams used to investigate the influence of concrete compressive strength, prestressing steel ratio and flange width on the behavior of partially prestressed beams. The experimentally observed behaviors of all beams were presented in terms of the cracking load, ultimate load, deflection, cracking behavior and failure modes. ID: 40170 Title: Safety Assurance for Challenging Geotechnical Civil Engineering Constructions in Urban Areas Name: Katzenbach Rolf Affiliation: Technische Universität Darmstadt E-mail: [email protected] ABSTRACT Safety is the most important aspect during design, construction and service time of any structure, especially for chal-lenging projects like high-rise buildings and tunnels in urban areas. A high level design considering the soil-structure-interaction, based on a qualified soil investigation is required for a safe and optimised design. Due to the complexity of geotechnical constructions the safety assurance guaranteed by the 4-eye-principle is essential. The 4-eye-principle consists of an independent peer review by publicly certified experts combined with the observational method. The paper presents the fundamental aspects of safety assurance by the 4-eye-principle. The application is ex-plained on several examples, as deep excavations, complex foundation systems for high-rise buildings and tunnel


con-structions in urban areas. The experiences made in the planning, design and construction phases are explained and for new inner urban projects recommendations are given. ID: 40200 Title: Pedestrian Countdown Signals: What Impact on Safe Crossing? Name: Janusz Supernak Affiliation: San Diego State University E-mail: [email protected] ABSTRACT This paper examines safety impacts of a Pedestrian Countdown Signal (PCS) installed on a busy downtown intersection in San Diego, California. Crossing episodes of over 5000 pedestrians were videotaped and analyzed using multivariate statistical methods. Details of timing of pedestrian crossing as well as information about vehicular traffic and signal timing were carefully coded for each pedestrian. Significant safety benefits of the PCS system were found on the long crossings over a street with high vehicular volumes: most pedestrians were able to effectively increase their walking speed to complete their crossing without committing the exit violation—even if they have already committed the entry violation. However, on the short crossing with light vehicular traffic, PCS was generally ineffective in preventing the entry violations from becoming exit violations. Over there, many pedestrians felt safe enough to walk over a short crossing with no apparent vehicular traffic in sight instead of waiting for a green signal. The length of crossing and volume of interfering vehicular traffic were consistently found the most significant variables affecting the crossing violation rates of different categories of pedestrians. Crossing violation rates were the highest for runners, bicyclists and older males. Crossing violation characteristics were found to be consistent over time.

ID: 40002 Title: Nurturing creativity – whose wisdom is of most worth? Name: Huzaina Abdul Halim Affiliation: University of Malaya E-mail: [email protected] ABSTRACT Researchers and practitioners interested in creativity have explored the concept at length. Wehner, Csikszentmihalyi and Magyari-Beck (1991) examined 100 doctoral dissertations on creativity and found a “parochial isolation” of various studies concerning creativity. There were relevant dissertations from psychology, education, business, history, sociology and other fields. However, different fields tended to use different terms and to focus on different aspects of what seemed to be a basic phenomenon. As instances of creativity are located in multiple domains and home, one of the learning outcomes in ‘The Malaysian Curriculum Specification for English language’ requires that students be able to express themselves creatively and imaginatively. A discussion about what we might call real creativity, and how we might develop pedagogies in fostering this, is long overdue. In this presentation, the researcher will also highlight on how creativity might be conceptualized and how creativity within education in particular might respond to this rapidly shifting world. I hope then to problematize creativity, and to propose ways in which pedagogies may be meaningfully developed or resurrected in the twenty-first century education. ID: 40003 Title: Differences between In-Field and Out-Of-Field History Teachers Influence on Students' Learning Experiences Name: Umi Kalsum Mohd Salleh Affiliation: University of Malaya E-mail: [email protected] ABSTRACT The focus of this study was to investigate whether there were differences between the way in-field and out-of-field teachers in Malaysian secondary schools perceived and practised History education, and the way their students perceived the teaching and learning of History. Both, teacher and student data were examined. A multivariate statistical analysis was conducted to validate the survey and test the relationships between variables. The results showed that there were significant differences between in-field and out-of-field teachers in the teacher characteristics of experience and student variables of classroom climate and History learning outcomes, but not on teaching approaches and methods. ID: 40053 Title: Measuring the Effect the Partners Dialogic Reading Program has on Preschool Children’ s Expressive Language Name: Brannon Diana


Affiliation: Elmhurst College E-mail: [email protected] ABSTRACT The effect the Parents as Reading Partners Nightly Encouraging Reading Success (PARTNERS) Dialogic Reading Program had on preschool children’s expressive language was studied. Researchers found that the videotaped training and materials were successful at increasing the expressive language skills of preschool children with developmental delays. Other program benefits such as increased time spent reading and talking between parents and their children were also found. ID: 40056 Title: The Effect of a New Placement Process on Student Success in First Semester Calculus Name: Fuller Edgar Affiliation: West Virginia University E-mail: [email protected] ABSTRACT In this work we describe the placement testing and student intake process at a large, land-grant university and show that long-standing general assessment exams administered during secondary schooling are not accurate predictors of success in university level mathematics courses. We then present results indicating that a placement exam administered during arrival as a first-year student provides a strong indicator of potential for student success in first-semester calculus. ID: 40094 Title: Small Group Dynamics in Cross-Cultural Collaborative Field Research: Voices from the Field Name: Karen Freeman Affiliation: Chicago State University E-mail: [email protected] ABSTRACT During the summer of 2010, researchers and student interns from Ghana Education Service, Chicago State University (CSU-USA), Winneba University of Education, and Cape Coast University took part in a collaborative field study to assess the extent of use and impact of CSU Teaching and Learning Materials Program (TLMP) in Ghana. Mixed teams of Ghanaian and US researchers visited 14 districts where the TLMP materials were distributed. They observed classrooms, interviewed parents and teachers, and collected end-of-year assessments. Before the fieldwork began, researchers attended a 9-day workshop on interview and observation techniques specific to cross-cultural teamwork. CSU students also took an orientation course during the spring semester. Every evening, after fieldwork, teams shared their experiences by telephone. Student interns kept a journal of their experiences. Both team leaders and student interns submitted reflections on the assessment, along with cross-cultural and methodological challenges encountered. After the field work, the program put together a one-day post-project forum when researchers shared the difficulties they faced and the opportunities they had while working together. The factors that influenced positive and harmonious group dynamics in cross-cultural collaboration included careful composition of teams, adherence to clear research procedures, and assignment of research tasks reflective of researchers’ backgrounds.


ID: 40095 Title: Evaluating Cultural and Technical Obstacles in School based ICT Programs: An Analysis of Two Case Studies Name: Judge Miriam Affiliation: Dublin City University E-mail: [email protected] ABSTRACT The emergence of a knowledge based economy has been identified as a central trend in modern economies as a result of the increasingly important role of information technology and learning in economic performance. In recognition of this most governments throughout the developed world have responded with a series of policy initiatives since the late 1990’s to either introduce or significantly increase information technology provision in schools to prepare students for life in the twenty first century. Ireland, with its growing reliance on the knowledge economy sector for employment and continued economic prosperity, developed its own policy initiative for computerising the nations’ schools known as ‘Schools IT 2000: A Policy Framework for the New Millennium’. It was an ambitious programme with high expectations for the integration of ICT (Information and Communications Technology) in education. This paper examines two longitudinal educational ICT projects in Ireland in the first decade of the new millennium to query how far schools have travelled along the information superhighway and to ponder how well the catalytic capabilities of ICT have become embedded in the realities of classroom life and teachers pedagogic practices, with attendant implications for Ireland’s economic development. ID: 40139 Title: Electronic Mentoring: What is it? Name: Gentry Roberta Affiliation: University of Mary Washington E-mail: [email protected] ABSTRACT Electronic mentoring is defined as a relationship between a mentor and a mentee using computer mediated communication (CMC) that is intended to develop and improve mentee’s skills, confidence, and cultural understanding. In the past, emphasis has been placed on the importance of a face-to-face community of professionals in producing maximum career success (Wellington, 2001), but changes in career patterns have opened the door to alternative mentoring approaches. Given the millions of worldwide Internet users and the increasing reliance on technology for personal and professional connectivity, individuals are utilizing email and CMC for relationship development (Sproull & Kiesler, 1999). E-mentoring offers distinct advantages including flexibility whereby mentors and mentees can connect when needed, regardless of geographical location and time constraints, in a format that mimics and expands traditional face to face interaction and in a way that increases solutions while simultaneously reducing costs of implementation and access (Smith & Israel, 2010). Additionally, trained mentors can be drawn from a much larger pool than that typically available locally. The online forum represents a complex learning environment in which collaboration is practiced in a technologically mediated environment and holds potential for new forms of collaborative work, study, and community that reduce barriers of time and distance (Kanuka & Anderson, 1998). This session will increase knowledge about electronic mentoring, its uses, and outcomes. This session will share the research behind electronic mentoring as well as descriptions of existing programs.


ID: 40140 Title: Electronic Mentoring for Beginning Teachers Name: Gentry Roberta Affiliation: University of Mary Washington E-mail: [email protected] ABSTRACT Beginning teachers need support if they are to become competent professionals (Reynolds, 1990) and induction programs are the critical link between theory learned at the university and application of theory in the school setting. Professional communities are built on teachers who regularly engage in discussions with colleagues about their work; however, teachers, especially novice teachers, often do not have the time and resources within their buildings for these meaningful interactions. Electronic mentoring environments offer these opportunities as well as access to underlying theories of learning (Hebert, Clift, & Wennerdahl, 2008). E-mentoring facilitates a community of learners sharing knowledge, skills, and values while simultaneously building new knowledge, skills, and dispositions within a safe, nurturing, and caring environment. E-mentoring provides an ideal format for bringing together groups of teachers from multiple schools allowing them to interact within a larger community rather than learning in isolation. Additionally, e-mentoring is designed to support novice teachers’ needs through differentiated experiences based on the mentee’s needs and immediate concerns (Smith & Israel, 2010). This presentation includes findings from a qualitative study which examined dialogues between beginning teachers and their mentors in an electronic mentoring site. Conversations were coded to determine the nature of the issues which dyads address, including beginning teachers’ concerns, professional competencies, and key factors identified in teacher development research. ID: 40141 Title: Electronic Mentoring: Do Special Education Mentors and Their Mentees Discuss Standards? Name: Gentry Roberta Affiliation: University of Mary Washington E-mail: [email protected] ABSTRACT The first year of teaching influences teachers’ development and their decision to continuing teaching (Borko, 1996; Nemser, 1983). Beginning teachers need support if they are to become competent professionals (Reynolds, 1990) as well as ongoing support to build their knowledge, skills, and dispositions. Traditionally, novice teachers have been matched with a school-based mentor; however, these relationships are limited to the expertise within their building and for many special educators, it is not possible to be matched with a mentor teaching similar students. Electronic mentoring allows individuals who are geographically separated to be connected, based on the expertise of the mentor. Mentees in a number of studies (Clift, & Cheng, 2005; Single, Muller, Cunmingham, Single, & Carlson, 2005) reported that online environments offer opportunities to connect with similar-minded individuals not readily available in the mentee’s building. Additionally, online environments have been found to be less threatening and more conductive to mentees sharing thoughts, perceived inadequacies, and doubts. This presentation will share an exploratory study that paired 50 novice special educators with 22 online mentors. The Interstate Teacher Assessment and Support Continuum (InTASC) Model Core Standards which outline what teachers should know and be able to do were used to qualitatively code the conversations between novice teachers and their mentors.

Title: Teachers’ Perception towards Total Quality Management Practices in Malaysian Higher Learning Institutions Name: Haque Ahasanul Affiliation: International Islamic University Malaysia E-mail: [email protected] ABSTRACT The service industry is a rapidly changing one and this dynamic culture offers a challenge for the service companies to lead or to actually survive in this competitive environment. As education industry is a part of the overall service industry, this raises the need for a solid base to be developed to reach for high quality service in the education industry. Though, adoption of TQM in the higher educational institutions is of common practices in the Western world, however, the history of TQM adoption in the Malaysian higher educational institutions is not very old. Therefore, the main purpose of this study was to identify the factors influencing the level of TQM practices in the Malaysian higher learning institutions based on the teacher’s perceptions. In doing so, this study was conducted in both types of Malaysian higher educational institutions (public and private). Total 300 questionnaires were distributed randomly, out of which 206 were returned. After collecting the data, statistical tests were performed using SPSS and Amos. This study has got satisfactory results. Results also show identical results with the previous studies. However, this study has pointed out that there are still rooms for improvement that affecting the level of TQM practices in the Malaysian educational institutions. Finally, future directions are provided at the end of the paper. ID: 40146 Title: Language Development: The Effect of Aquatic and On-Land Motor Interventions Name: Ram-Tsur Ronit Affiliation: Bar-Ilan University E-mail: [email protected] ABSTRACT The aim of the current preliminary research was to examine the relationship between aquatic motor activities and language abilities. Our hypothesis suggests that changing the environment to water may improve motor and linguistic abilities. The study included 94 children between the ages of four and six. Thirty-one children who participated in aquatic motor activities were compared to 41 children who participated in on-land motor activities and to 21 children who participated in non-motor activities. Developmental-functionality tests, including gross and fine motor, time estimation and language tests, were used to diagnose participants' abilities before and after six months of intervention. We found significant improvement in gross motor, fine motor and time estimation abilities for the aquatic motor activities group. Moreover, improvement in gross motor and time estimation abilities moderated the association between aquatic motor activities and children’s naming ability, suggesting the positive effect of aquatic motor activities on language abilities. Based on these novel findings, child-development professionals can have a better understanding of relation between language abilities and motor abilities, possibly leading to an improvement of intervention methods with early-childhood patients. Early childhood intervention could aid in reducing primary differences between children in motor abilities, and especially in motor-development disorders, which in turn are thought to lead to additional learning disabilities. ID: 40151 Title: Knowledge Management and Action Learning in Blended Training Activities


Name: Chandavimol Pattama Affiliation: Chulalongkorn University E-mail: [email protected] ABSTRACT The purpose of this study is to propose blended training activities by applying the knowledge manage-ment techniques and action learning into the training process. The proposed data are from study of the theory, documents, surveys, problems, and needs in knowledge Management and Action Learning to develop blended training techniques. The questionnaires were answered by 261 respondents who are personnel development staffs experienced in designing training courses, organizing these courses, and writing up training projects for government units in Thailand. The process development was brought to discussion with 5 field experts in distance learning, training, instructional design and curriculum development, Educational Technology and Communication, and organization development areas. The data were analyzed using basic statistical techniques such as frequency distribution, percentage, descriptive and open-ended surveys, brought to analyze and categorize the information, then propose the findings. The key findings show that organizing the blended training process consists of 3 steps: pre-training, training, end-of-training. In each step, the blended activities, traditional classroom training, online and E-Learning are used with knowledge management activities and action learning. Then using technology to enhance learning processes such as blogging, chat, discussion boards, e-mail, E-learning courseware, and learning management systems. ID: 40155 Title: Bulk Simulation Data in Programming Class Name: Kraikruan Tana Affiliation: Green Cyber Advance Co.,Ltd. E-mail: [email protected] ABSTRACT This paper discusses a few issues related to Development of Learning Environment to solve problem that are commonly found from IT graduated student from college and university, Which cannot solve and manage mega transaction of database from reality business. ID: 40157 Title: Education for Social Responsibility: The use of CSCL in undergraduate service-learning modules Name: Anchana Sooksomchitra Affiliation: Chulalongkorn University E-mail: [email protected] ABSTRACT The purpose of the study was to develop an educational module for undergraduate student that effec-tively supports a project-based learning, and to cultivate a sense of students’ social responsibility. The researcher recognizes computer-supported collaborative learning (CSCL) as a powerful tool in supporting students to share their meaningful learning activity and project. The tool can vastly and conveniently broaden the students’ learning experience and facilitate different learning needs of individual student efficiently. ID: 40159


Title: A Comparative Study of Two Schools: How School Cultures Interplay the Development of Teacher leadership in Mainland China Name: Wang Feiye Affiliation: the University of Georgia E-mail: [email protected] ABSTRACT This article seeks to gain an understanding of the interrelated relationship between school cultures and the teacher leadership development by comparing the experience of teacher leaders’ from two middle schools in China that exhibited different kinds of school culture. The researchers argue that the better the school culture was, the more prospective Teacher leaders would develop and the better Teacher leaders would enact their leadership, which further would reinforce the building of a healthy school culture. ID: 40175 Title: Analysis of Pupils’ Difficulties in Solving Questions Related to Fractions: The Case of Primary School Leaving Examination in Tanzania Name: Ndalichako Joyce Affiliation: National Examinations Council of Tanzania E-mail: [email protected] ABSTRACT In this paper, analysis of the performance of candidates in Mathematics in Primary School Leaving Ex-amination was conducted with the aim of highlighting difficulties encountered in solving fraction related problems. The analysis has indicated that a considerable number of candidates could not perform correctly operations related to fractions. They tended to confuse fraction concepts with whole number concepts. For instance, in questions involving addition of fractions, they were treating numerators and denominators as separate entities. Possible reasons for such difficulties in solving questions related to fractions include lack of understanding of appropriate procedures to apply in solving a problem, the complexity of the task, over-generalization of procedures even in situations which are inappropriate. It is recommended that a protocol analysis be conducted in order to gain a deep understanding of the thought process of candidates when attempting questions related to fractions so that teachers may use relevant teaching methods that would facilitate meaningful learning of fractions. ID: 40017 Title: Metaphors Used by Malaysian Teachers-In-Training: Implications for Language Teacher Education Name: Hasim Zuwati Affiliation: University of Malaya E-mail: [email protected] ABSTRACT Over the past 20 years, there has been increasing interest in exploring what language teachers believe (Borg, 2006). Often these beliefs are expressed in terms of metaphors (Richards, 1998; Woodward, 1991), but there has been little recent research connecting the two strands. The present study is based on the online reflections of a group of 74 trainee teachers in a Malaysian University after a three-month practicum in local high schools. In these reflections, as well as currently fashionable constructs such as facilitator and motivator, these students often described their


perceptions of the role of the language teacher using various metaphors. The wide range of metaphors volunteered by these trainee teachers were coded into various categories, such as terms relating to kinship, other professions, mentorship, and entertaining. This presentation will discuss a number of these, and also quote some of the trainees’ comments in support of their chosen metaphor, which thereby reveal their underlying beliefs about teaching Relating their professional activity to other roles illuminates not only what teachers themselves believe, but also reinvigorates notion of (language) teaching itself. One of the implications of this study is that teacher educators, both in the specific setting and in relatable contexts elsewhere, can incorporate such metaphors into their programmes and in this way reimagine, refine and redefine the role of the language teacher for the benefit of their students, and themselves.

Invited Speech: Discrepancies of Surface Temperature and Precipitation

Trends in the CMIP5 Simulations and Observations on the Global and

Regional Scales

Floor, Beijing Yanshan Hotel Abstract We consider the Arctic and the southwestern US climate and use a multiple regression of regional mean temperature to separate

anthropogenic forcing from natural climate variability. We find that both regions are influenced by increasing concentration of

GHG sand natural climate variability represented by the Atlantic Multi-decadal Oscillation(AMO) and Pacific Decadal Oscillation

(PDO).The early 20thcentury Arctic warming was dominated by the AMO with only minor contributions from the GHGs, solar

variability and volcanic activity. The late (post1975)20thcenturyArctic warming was about equally divided between the

anthropogenic GHG sand natural climate variability (AMO). Any future Arctic climate projection that does not include the AMO is

in a danger to significant layover estimate future warming. This is also true for regional climate where the AMO signal is strong

like in the southwestern US.

Speaker: Prof. Jianjun Xu, George Mason University, USA Time: 09:10-09:50, September 21, 2013 Location: PLUM BLOSSOM ROOM (沁梅厅) 2nd Floor, Beijing Yanshan Hotel Abstract Using the fifth Coupled Model Intercomparison Project (CMIP5) model simulations and observational datasets, the surface

temperature and precipitation trends and their discrepancies have been examined. The temporal-spatial characteristics for the trends

are discussed. Different from a constant estimated linear trend for the simulation period, a dynamical trend using running linear

least squares fitting with the moving 10-year time windows are calculated. The results show that the CMIP5 model simulations are

generally in good agreement with the observational measurements for the global scale warming, but the trends depend on the

temporal change and the regional differences. Generally, contrary to the small discrepancies on the global scale, the large

discrepancies are observed in the south- and north-polar regions and other sub-regions.

ID: 40018 Title: Experimental Study of Invasion and Biofouling of Freshwater Mussel Limnoperna Fortunei Name: Xu Mengzhen Affiliation: Tsinghua University E-mail: [email protected] ABSTRACT Golden mussel Limnoperna fortunei (Dunker 1857) is a filter-collector species of fresh water mussel originating from southern China. In the water transfer tunnels from the East River to Shenzhen and Hong Kong, golden mussels attach to the walls of pipelines and gates, causing serious biofouling, increased flow resistance, and resulted in corrosion of the tunnel wall. Golden mussel has very high environmental adaptability and may colonize habitats with low dissolved oxygen and a wide range of trophic levels. The colonization process of the species on solid surface was studied in the Xizhijiang River, a tributary of the East River and the main water resource of Shenzhen from March 2010 to April 2011. The results showed that the golden mussel completed three generations and reproduced six cohorts per year in the tropic zone. Water temperature was the controlling factor for the growth rate and maturity of each cohort. Based on the results, an ecological method for controlling the invasion of golden mussels in water transfer tunnels was proposed. ID: 40048 Title: Evaluation of Desertification Processes in Serido Region (Ne Brazil) Name: Petta Reinaldo Affiliation: Federal University of Rio Gde do Norte E-mail: [email protected] ABSTRACT This paper outlines procedures to analyze the desertification processes in the semi-arid Seridó Region (NE Brazil). Using the Geosystem theory, the detection of desertification areas was based on environmental indices, digital image pro-cessing in multispectral analysis and Geographic Information System (GIS). In a first step were treated the rainfall data and NDVI satellite Modis, aiming at identifying areas which do not present vegetation cover, even during the rainy seasons. In a second step, were work on a regional scale using Landsat ETM + images (2000-2005) and data collected in the field, as the evaluations of exposed surfaces, that together with MDT / SRTM-NASA and thematic maps, allowed classify the altitude and slope of the relief, soils type, different morphologies and geology, and correlate them with the areas susceptible to desertification process. The integration of the georeferenced data, related to these indicators, allowed the identification of five different levels of susceptibility to desertification (very high, high, moderate, low and very low), and the geographic domain of each class. Based on the analysis of the dynamics of the vegetation cover, we can establish that the main results refer that there is a decrease of the biomass at the region, associated either with the dense caatinga vegetation areas, but more important, with the scrub and degraded areas.

Parameterization Intercomparison and Impacts on Aerosol Indirect Effects Name: Xin Zhang Affiliation: North Carolina State University E-mail: [email protected]

ABSTRACT Aerosol activation is a crucial process for aerosol-cloud interactions that yet represents yet another one of the largest uncertainties in climate research. It affects cloud droplet number concentration (Nc) and mass mixing ratio (Qc), which determine cloud radiative forcing, lifetime, and precipitation. To explore the behavior of the National Center for Atmospheric Research’s Community Atmospheric model (CAM5) physics for high-resolution global and regional modeling, PNNL recently coupled the Weather Research and Forecasting (WRF) model with the physics package from CAM5 (i.e., WRF-CAM5). WRF-CAM5 is further improved by parameterizing aerosol effects on deep convection and improving ice nucleation parameterizations for mixed-phase and ice clouds.In this work, WRF-CAM5 is further developed by incorporating an advanced, physically-based aerosol activation parameterization from an extension of Fountoukis and Nenes (2005) (FN05) and includes dry air entrainment, adsorption activation from insoluble CCN, and giant CCN equilibrium timescale (FN05_extended). To study the impact of these parameterizations on aerosol direct and indirect effects (i.e., cloud, radiation, and precipitation), a set of simulations with FN05, FN05_extended, and the default Abdul-Razzak Ghan (2000) parameterization (AR-G00) are being conducted for the years of 2005 and 2010 over East Asia where anthropogenic aerosol emissions are large. Preliminary results for the July 2005 simulation show that FN05 gives 43% and 33% and FN05_extended gives 63% and 9% higher CCN than AR-G00 for non-convective and convective clouds, respectively. The treatments of giant CCN and convective entrainment suppress CCN generation by 9% and 23%, respectively. Under conditions with high emissions of dust and black carbon, 26% more CCN can be generated from insoluble particles through adsorptive activation. Nc and Qc from non-convective clouds increase with increasing CCN. Despite higher water content in cloud, non-convective rain is suppressed by more than 2% with increased CCN because warm rain formation process is less efficient due to reduced droplet size. In addition, more shortwave radiation (on the order of 1.0 W m-2) is reflected back to space, due to increased cloud fraction and cloud albedo resulted from more Nc but smaller droplet size. These results demonstrate that the simulated aerosol indirect effects are sensitive to aerosol activation parameterizations with varying degrees of physical treatments. ID: 40075 Title: Effects of Temperature upon Water Turnover in Fish Ponds in Northern Thailand Name: Patcharawalai Sriyasak Affiliation: Maejo University E-mail: [email protected] ABSTRACT Fish culture in earthen ponds is an important source of income for farmers in northern Thailand. Water quality in ponds has strong impacts on fish production farmers’ return and is sensitive to weather and climate. Low levels of dissolved oxygen in fish ponds are major cause of mass mortality. Stratification with depth in ponds followed by rapid turnover or exchange of surface and bottom water can expose fish to dangerously low dissolved oxygen levels. The main pur-pose of this study was to observe the effects of weather on stratification and subsequent water turnover in fish ponds in northern Thailand, especially in the winter and rainy season, when stratification was expected to be most severe. Temperature and water quality measurements were made in fish ponds at 18 farms with depths ranged from 0.8-2.0 m and size of 0.16-0.64 ha. Measurements were made during January and May 2013. Fish farm pond sites


were divided into two groups based on elevation above sea level: low (< 400 masl) and high (> 400 masl) and categorized into 3 types of farming: commercial, integrated and subsistence. In lower elevation sites, water turnover occurred at night between 22.00 and 02.00 in winter and between 18.00 and 02.00 in rainy season. At higher elevation, turnover oc-curred in ponds between 20.00 and 22.00 in winter and between 14.00 and 18.00 in rainy season. Turnover was slower in the lower elevation than in higher elevation zones and generally occurred earlier during the rainy season than in the winter. Mean DO in winter was significantly higher (P<0.05) than in rainy season, whilst water temperature and amount of ammonia-nitrogen during the rainy season was significantly higher (P<0.05) than in winter. Turnover improves distribution of dissolved oxygen through the water column and minimizes organic matter accumulation. Cloud cover during the rainy season may have contributed to limit oxygen production and thus may have significantly affect water quality in ponds. Fish farmers should consider more explicitly the role of temperature and cloud conditions when managing dissolved oxygen levels in their fish ponds. Therefore, efficient pond aeration or pond mixing strategies for reducing stratification still plays an important component for providing sound pond management in tilapia production ponds. ID: 40079 Title: Geosmin Sorption on Cyclodextrin Polymers Name: Gutierrez Redel Affiliation: Maejo University E-mail: [email protected] ABSTRACT Geosmin is one of the major causative compounds of earthy-musty odor and taste (off-flavor) in drinking water (lakes) and in farmed fish. In this study, the sorption of cyclodextrin polymers (CDPs) towards geosmin in aqueous solution was investigated. Sorption kinetics, the effect of solution pH and contact time on the sorption capability of α, β and γ-cyclodextrin polymers was discussed. Results disclosed that the sorption of geosmin by the CDPs followed the Ho and McKay kinetic mechanism with the liquid film diffusion as the rate-determining step. Both β-CDP and γ-CDP exhibit high removal efficiencies of 93.4% and 96%, respectively, within 240 minutes at 25oC and pH 7, whilst α-CDP was not as effective, removing only 40% geosmin, at an initial concentration of 5 µg L-1 and 5 g L-1 of CDP dose. The cyclodextrin polymers can adapt to a wide range of pH from 3.0 to 11.0 for geosmin adsorption with pH 7.0 as opti-mum. Results indicate that these sorbents demonstrate significant potential in reducing the concentration of geosmin in water that presents taint problems in both drinking water and fish. ID: 40080 Title: Extreme Events Assessment Methodology Coupling Debris Flow, Flooding and Tidal Levels in The Coastal Floodplain of the Sao Paulo North Coast (Brazil) Name: Sakai Rafael Affiliation: Polytechnic School of Sao Paulo University E-mail: [email protected] ABSTRACT The North Coastal Region of the State of Sao Paulo, which comprises the Municipalities of Caraguatatuba, Sao Sebastiao, Ilhabela and Ubatuba, is one of the most prone to flooding and debris flow deposition Brazilian areas, owing to hydrological extreme rainfall events usually coupled with extreme tidal levels. This risk is also high due to human lives and material assets, with increasing population rates and the establishment of large Companies such as


the Oil industry, with reduced defense/prevention measures and works. The catastrophic scenario of the city of Caraguatatuba, in March 1967, resulting from one of the most serious natural disasters in Brazil, fosters discussions about probabilities of heavy rainfall-caused events and rise in the sea level in coastal areas. Hence, this research is a consequence of this reality. The research is founded on an innovative methodology based on the analysis of past data of rainfall and tidal stations, complemented with debris flow registers in the region of the North coastal zone of the State of Sao Paulo (Brazil). The analysis developed involved the meteorological, hydraulic, geotechnical and statistical knowledge areas. Practical results are intended to be used for urban planning, designs of macro-drainage, fluvial, maritime projects and debris flow retention structures. These practical applications will then associate the probability of occurrence of certain types of heavy rainfall-caused events such as flooding or debris flow coupled with a corresponding increase in tidal levels. ID: 40125 Title: Legal Issues and Scientific Constraints in the Environmental Assessment of the Deepwater Horizon Oil Spill in Mexico Exclusive Economic Zone (EEZ) in the Gulf of Mexico Name: Soto Luis Affiliation: UA-Oceanic and Coastal Processes-Instituto de Cien E-mail: [email protected] ABSTRACT The largest accidental marine oil spill (4.9 million barrels) in the Gulf of Mexico (GoM) seabed (1600 m) caused by the sinking of the Deepwater Horizon oil rig in 2010, put to the test once again the resilient capacity of the pelagic and benthic realms of this Large Marine Ecosystem. Many are the ecological services provided by its waters (fisheries, tourism, aquaculture and fossil fuel reserves) to neighboring countries (US, Mexico and Cuba). However, the unprecedented volumes of hydrocarbons, gas and chemical dispersants (Corexit) introduced in the system, represent ecological stressors whose deleterious effects are still the subject of civil claims and scientific controversy. Presumably, the short scale effects were confined to the Gulf’s northeastern shallow waters, and the combined actions of weathering, biodegradation, and oil recovery left the system almost under pre-spill conditions. Unfortunately, surface and subsurface oil plumes were detected in the spill aftermath, and their dispersion trajectories threatened Mexico EEZ. Surface oil slicks were detected in the pristine waters of northern Yucatán, while subsurface oil plumes from the Macondo’s well blowout were dangerously advancing southwest towards key fishing grounds in the northwestern GoM. This disaster prompted the Mexican government to implement an ambitious ocean monitoring program adopting a bottom-up approach focused on building a base line for more than 42 physicochemical and biological variables for water, sediment and biota from the continental shelf-slope region of the NW GoM.Technological constraints have precluded systematic observations in the vast Mexican EEZ that could discriminate natural variability and oil seep emissions from antropic disturbances. Therefore, preliminary risk analyses relied on seasonal and historical records. Two years of field observations revealed subtle environmental changes in the studied area attributed to antropic disturbances. Waters maintained oligotrophic conditions and zooplankton and benthic infaunal biomass were also poor. Biomarkers in sediments and biota did not exceed EPA’s benchmarks, and sediment’s fingerprinting (δ^13 C) indicated marine carbon sources. Geomarkers revealed an active transport from the Mississippi towards the NW GoM of phyllosilicates bearing a weathered oil coating. Consequently, shelf and slope sediment toxicity begins to show an increasing trend in the region. The complexity of hydrocarbons bioaccumulation and biodegradation processes in deep waters of the GoM seems to indicate that meso- and large-scale observations may prove to be essential in understanding the capacity of the GoM to recover its ecological stability.


ID: 40161 Title: Relationships of Dissolved Oxygen with Chlorophyll-a and Phytoplankton Composition in Tilapia Ponds Name: Kunlasuk Kornkanok Affiliation: Maejo University E-mail: [email protected] ABSTRACT This study investigated the relationships among the parameters of dissolved oxygen, chlorophyll-a and phytoplankton composition in tilapia ponds. Each pond (a total of 18 ponds) was sampled once in the dry, winter season between January and March and again early in the rainy season between May and June. The data were analyzed by examining correlations among parameters as affected by season, altitude and culture system. Observations were made at sites located in 5 selected provinces of northern Thailand: Chiangrai, Chiangmai, Phayao, Lampang and Nakornsawan. Mean elevation of these areas range from 25 to 582 meters above sea level (masl) and were categorized into low (<400 masl) and high (>400 masl) elevation sites. Ponds were 0.8-2.0 m deep, 0.16-0.64 ha in area and could be further cate-gorized into high and low input systems.Mean air temperature in winter ranged between 16.5-35.8˚C while mean water temperature ranged between 25.5-27.1˚C. In rainy season, air temperature ranged between 22.0-37.3˚C and water tem-perature ranged between 29.4-31.8˚C. The amount of chlorophyll-a in both seasons were comparable (p>0.05), but chlorophyll-a in high input system was significantly higher (p<0.05) than in low input ponds. Only weak correlation was found between chlorophyll-a, DO max and DO min. Multifactor-ANOVA was used to analyze the difference of total bac-teria and filamentous cyanobacteria in ponds based upon elevation, culture systems and season. Result shows that there is a significant interaction observed between elevation, culture system and season (p<0.05). Species diversity and composition of phytoplankton in fish ponds in 2 seasons revealed the presence of 90 genera of phytoplankton under all 7 divisions. Divisions Chlorophyta and Cyanophyta had the most number of genera identified in both seasons with Pediastrum spp., and Scendesmus spp., and Anabaena spp. as dominant genera/genus, respectively. ID: 40171 Title: Survey of Climate-Related Risks to Tilapia Pond Farms in Northern Thailand Name: Pimolrat Pornpimol Affiliation: Maejo University E-mail: [email protected] ABSTRACT Climate is an important factor for aquaculture production. This study aimed to understand how farmers that culture tilapia in earthen ponds perceive and respond to climate impacts. Important climate-related risks identified include extreme temperatures (hot and cold), excessive rainfall, prolonged cloud cover, flood and drought. Site visits and data collection using questionnaires were conducted to identify important factors influencing farm profits, losses, decision to increase or decrease ponds. Special attention was given to knowledge about fish markets and weather and the impacts of weather and climate on fish growth, disease outbreaks and water quality in ponds. Altogether 585 fish farms in four provinces in northern part of Thailand selected to cover a range of elevations above sea level and thus climate were surveyed (Nakornsawan< 100 m, Lampang 100-300 m, Phayao 300-500 m and Chiang Mai > 500 m). Fish farms at different elevations reported different climate and weather-related impacts. In the area where elevation above sea level is < 100 m, farmers were affected more by floods and extreme hot weather which caused fish deaths and stress that reduced feeding and growth rates. Conversely, fish farmers in the area where elevation


above sea level is >500 were impacted mainly by drought and cold weather. These conditions also caused disease outbreaks and reduced feeding rates. Farmers responded by reducing the amount of feed supplied and considering non-fish pond or non-farm supplementary occupations as an adaptation strategy. Among non-climate related factors high prices of feed were most commonly identified as a key issue by farmers. The differences among sites at higher and lower elevation provided insights into the kind of changes in risks farmers may face as climate changes that could be helpful in developing adaptation strategies for individual farmers and the sector as a whole. ID: 40177 Title: Microcystin Accumulation in Nile Tilapia, Oreochromis Niloticus and Giant Freshwater Prawns, Macrobrachium Rosenbergii in Green Water System Cultivation Name: Ruangrit Khomsan Affiliation: Chiangmai University E-mail: [email protected] ABSTRACT Phytoplankton including blue-green algal or cyanobacterial blooms frequently occurred in aquaculture ponds. Some cyanobacteria produced cyanotoxins that may accumulate in the food web and eventually in the aquaculture products. In this study, accumulatation of microcystins in Nile tilapia (Oreochromis niloticus) and giant freshwater prawn (Macrobrachium rosenbergii) cultured in green water system was investigated. Nile tilapia was cultured in green water system and fish food; green water system with Microcystis aeruginosa Kützing and fish food and green water system with M. aeruginosa. Giant freshwater prawn was cultured: in green water systems with and without toxic M. aeruginosa. Microcystins of 8.32+0.76 and 9.35+1.45 μg.kg-1 d.w. were detected in fish cultured in green water system with M. aeruginosa and fish food and in green water system with M. aeruginosa, respectively. Microcystins of 14.42+1.63 μg.kg-1 was found in prawn samples. It implied that aquaculture products were likely to be contaminated with microcystins. This finding is useful for aquaculture in terms of food safety.
