Title: The models of structural mechanics in geodesy and geodynamics: a case study of finite element method

Abstract: The methods of structural mechanics play an indispensable role in many branches of the modern world. However, the application of these methods for geodesy and geodynamics was quite modest for the last half-century. The invention of the finite element method (FEM), as a calculus approach, had changed the state crucially. The development of both the FEM and high-productive PCs was going hand in hand. Thanks to it, today, we got a chance to employ the benefits of these advancements and apply them for particular tasks of geodesy and geodynamics. The primary goal of this study is to analyze and embrace the current experience of FEM application. The analysis stems from different employment of the FEM, namely for geodesy (adjustment geodetic computations, coordinates transformation), applied geodesy (accuracy assignment for geospatial monitoring and staking-out of engineering structures, geospatial monitoring results analysis, temperature influence accounting), and geodynamics (stress-strain state simulation for crust movements study and prediction, gravitational field simulation). The solutions to all of those issues were examined using FEM. Based on that, was attempted to develop the general approach of the FEM application for geodesy and geodynamics. The general concept of the FEM application for geodesy and geodynamics was suggested. Finally, the prospective researches of the FEM application in geodesy and geodynamics were determined.

DR. ONG MENG CHUAN

Faculty of Science and Marine Environment, Universiti Malaysia Terengganu

Research Area: Metallic Elements Pollution in Sediment and Biota, Sedimentological Analysis, Sedimentation Rate Analysis


Dr. Ong Meng Chuan is an Associate Professor of marine science at Faculty of Science and Marine Environment, Universiti Malaysia Terengganu (UMT). He holds a doctoral degree in 2012 with a research background in marine pollution from University of South Brittany, France. Recently, he was appointed as coordinator for Marine Science Program and Associate Fellow at the Institute of Oceanography and Environment, one of the Higher Centre of Excellent (HiCOE) under the Ministry of Higher Education of Malaysia. To date, he has published more than 70 research articles in scientific journals, chapter in books and conference papers. He has participated in numbers of international conference and local conference in Malaysia to present his findings. He is currently mentoring 5 postgraduates who are pursuing their Ph.D. and M.Sc. degrees by research. He has also successfully guided 9 postgraduate students (1 Ph.D. and 8 M.Sc.) as main and co-supervisor until project completion and graduation. Besides, he has also supervised 51 undergraduate final year research projects as main supervisor. Dr. Ong areas of expertise include the marine pollution specifically heavy metals pollution. He is actively engaged in research and recently form a research interest group, Ocean Pollution and Ecotoxicology (OPEC) Research Group among UMT researchers and also from other institution in Malaysia. His research focus on the metals content in sediment samples which can act as geo-marker for pollution studies. Apart from the sediment samples, his research also included on biota samples of fishes, crustaceans, bivalves, mollusks and plants such as seaweed and sea grass. Currently, he and OPEC’s researchers is actively gather all data from Malaysian marine aquatic environment related to pollution to be stored in GIS database. With this database, these data can easily referred by other researchers for their studies.


Title: Marine Pollution in Malaysia Aquatic Environment: A Review of Heavy Metals in Sediments and Living Organisms

Abstract: Heavy metals contamination has drawn increasing attention environmental problem including Malaysia through disturbing the normal functions of aquatic system. These pollutants are a worldwide problem because these chemical elements are indestructible and most of them have toxic effects on living organisms, when they exceed a certain concentration. With the rapid industrialization and economic development in the coastal region, these pollutants are continuing to be introduced to estuarine and coastal environment through rivers, runoff and land–based point sources where the chemical elements are produced as a result of metal refinishing by products. Heavy metals concentrations in harbour or estuarine sediments usually are quite high due to significant anthropogenic contaminants loading carried by the upstream of tributary rivers. The sediments serve as a metal pool that can release metals to the overlying water via natural or anthropogenic processes, causing potential adverse health effects to the ecosystems. Therefore, they are widely used as geo–markers for monitoring and identifying the possible sources of pollution in the coastal environments. On the other hand, marine aquatic organisms such as fishes, bivalve and mollusc can accumulate heavy metals from various sources in their surrounding environment. The accumulation of heavy metals in marine aquatic organisms can pose a long–term burden on biogeochemical cycling in the ecosphere. Once the heavy metals enter the food chain, they may accumulate to dangerous levels and be harmful to human health. In order to estimate the human health risk assessment, PTWI were calculated and all the data were compared to Malaysia Food Act and Malaysia Food Regulation.
