Time Lapse (4d) Seismic Signal Detectability Improvement Using Co-Processing Technique On Carbonate Reservoirs
(2023-11)
Mohamed Mahgoub, Mohamed Abdelghany
4D seismic studies are used to monitor the performance of hydrocarbon reservoirs during production or injection phases. Repeated 3D seismic surveys must be able to measure a 4D signal that can detect fluids substitution or pressure changes that may take place during reservoir production or injection of water or gas over a period of time. In practice, the seismic signal allied with such changes could be perceptible in clastic reservoirs whereas it could be negligible in heterogeneous carbonate reservoirs. Repeating 3D seismic surveys with the same acquisition geometry is usually difficult in the Middle East due to environmental changes (e.g., rough terrain, water currents, seasonal changes, and field production installations). Therefore, three oil and gas fields of offshore Abu Dhabi in the United Arab Emirates with scarce seismic acquisition repeatability have been selected for this study. In this study, the 4D seismic co-processing for the three case studies differs from the input data, whether it starts from the seismic field data or from different pre-processing and deconvolution, or whether it starts after the same deconvolution on base and monitor seismic surveys.

Effects Of Road Geometry And Roadside Trees On Urban Road Thermal Performance In Penang
(2016-06)
Mirzaei, Nasibeh Faghih
This research investigates the effects of the physical road characteristics and roadside tree features on the road thermal performance in Penang, Malaysia; located in tropical region where there is high solar radiation intensity. The variables of urban road features studied include road width and road orientation. Accordingly, the effects of physical properties of roadside tree takes to accounts, including tree position, tree height, canopy density and tree distance from the road edges. The research methodology is quantitative in nature via fieldwork measurements to assess the road thermal performance. The study measures road surface temperature and air temperature above road surface in accordance with research objectives and hypotheses. The research findings illustrated the significant effects of road and tree characteristics on road surface temperature and air temperature. Based on road orientation and width, North West-South East wide roads had the highest average surface temperatures. However, North-South oriented narrow roads provide a better urban road microclimate. Moreover, tall trees with dense canopy had the most significant effect on road surface temperature reduction by providing high quality shade. The results also revealed remarkable differences of road thermal performance between road with trees and without trees. Finally, the conclusion from the potential cooling effects of roadside trees and road characteristics on the road thermal performance can be implemented as a guideline of urban road design in modification road microclimate in urban tropical region.
A Study Of The Relationship Between The Big Five Personality Dimensions And Job Involvement In A Foreign Based Bank/Financial Institution Institution In Penang
(2008)
Eswaran, Sivaram
The relationship between the Big Five Personality Dimensions and job involvement was examined in a questionnaire study with a sample of one hundred and five (105) sales/customer service staff of a foreign based banking/financial institution in the Northern Region of Malaysia. Hypotheses were tested by means of hierarchical regression with the inclusion of a few moderating factors.

Conventional Organic Solvents And Ionic Liquid Mediated Synthesis Of New Azomethine Compounds As Potent Cholinesterase Inhibitors
(Universiti Sains Malaysia, 2016-01)
M. Abd Razik, Basma
Five new series of azomethine derivatives were synthesized by condensation of substituted benzaldehydes and amino derivatives in ethanol a conventional organic solvents and a green ionic solvent, 1-butyl-3-methylimidazolium bromide ([bmim]Br), respectively. The green ionic solvent [bmim]Br, due to its remarkable catalytic effect has several remarkable advantages over ethanol in terms of high product yields and short reaction time. Condensation reactions performed in an ionic solvent had resulted in a significant increase in product yields ranging from 18 to 29 % and 6-15 times decrease in reaction time as compared to similar reactions performed in ethanol. The azomethines were characterized using elemental analysis, FT-IR, 1-D and 2-D NMR spectroscopy as well as X-Ray crystallography. The synthesized compounds were also evaluated for their potency against Alzheimer’s disease using the Ellman’s colorimetric assay. In this assay, the cholinesterase inhibitory activities of the aforementioned compounds were screened in vitro against acetylcholinesterase (AChE) of electric eel and butyrylcholinesterase (BChE) extracted from equine serum, both of which play a major role in the manifestation and progression of Alzheimer’s disease. The results revealed that azomethine derivatives in series 9 displayed relatively better AChE inhibitory activities than those in series 3, 5, 7 and 11. This observation is presumably due to the presence of three aromatic cores in compounds series 9, which may facilitate the insertion and accommodation of these compounds in the AChE active site gorge. However, compounds of series 5 are also composed of three aromatic cores, but the presence of a carbonyl moiety in the structure of these molecules plausibly hinders their insertion and positioning in the active site gorge of the AChE enzyme. Besides, in term of AChE inhibition compounds 3g, 3j, 5j, 7f, 7g, 7j, 9f, 9h, and 11h showed high inhibitory activities which are comparable to the inhibitory activity of the standard drug, galanthamine. A similar observation was seen for compounds 3j, 5j, 7j, 9h and 11j in BChE inhibition. An in-silico molecular modeling analysis was also employed by using the crystal structure of Torpedo californica AChE (TcAChE) and human BChE (hBChE) to disclose the orientation and binding interaction mechanism of the active compounds inside the active site gorge of AChE and BChE receptors, respectively. Molecular dynamics (MD) simulation on silicon were used to obtain information in order to characterize the interactions between the active compounds and the related protein AChE and BChE, respectively. The stability of the ligand-protein complexes was evaluated based on their root mean square deviation (RMSD). In this study, the RMSD values of the active compounds, which complexed with AChE and BChE, respectively are less than those of the uncomplexed cholinesterase enzymes. This result indicates that the conformations of the ligand-protein complexes had achieved equilibrium and exhibit low fluctuation due to strongly tied up and binding with related proteins, thus leading to the inhibition of the cholinesterase enzymes. All these results are consistent with the observation in the biological assays.
Mineral characterization study of gold deposit in tawau, sabah focusing on mineralogy and geochemistry
(2022-08-19)
Maijin, Richell
Tawau gold mine is included in the low sulfidation epithermal gold deposit system. The gold deposit is within the Tawau Peninsular. The Tawau Peninsular is underlain by the Oligocene to Middle Miocene sediments of the Kalumpang formation that consist predominantly of mudstone and shale with inter-bedded sandstone, conglomerate, limestone, and rare chert. The research purpose is to analyze the mineralogy and geochemistry of gold vein deposits and determine the system of the ore deposits. The mineral characterization study is an important stage in the development and operation of mining and mineral processing systems. The minerals' chemical composition, size, morphology, and association are all factors influencing the attraction of the deposit or products produced from it, and therefore their success as a commercial venture. The method employed in this study is a combination of X-Ray Fluorescent (XRF), Micro X-ray Fluorescence (µXRF), Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), Scanning Electron Microscopy (SEM) and X-Ray Diffractometry (XRD). The study of the sample revealed the presence of pyrite, chalcopyrite, bornite, sphalerite, galena, and quartz as the main gangue mineral. Gold is not observed as free gold and possibly occurs as a sub-micron scale or solid solution. Based on those characteristics of the mineralogy and geochemistry this study showed that low sulfidation epithermal gold ore deposit in this area is refractory ore with high base metals.
