1. THE EFFECT OF CU ON NI/γ-AL2O3 CATALYST FOR THE THERMAL DECOMPOSITION OF METHANE: AN AB INITIO MOLECULAR DYNAMICS INVESTIGATION

Authors: GIAN PAOLO O. BERNARDO , HIROFUMI HINODE , JOSEPH AURESENIA , LEONILA C. ABELLA

Abstract: This study focuses on the catalytic decomposition of CH4 for the production of carbon nanotubes (CNTs). The decomposition of a single CH4 molecule on Ni/γ- Al2O3 catalyst surface with and without Cu was observed via ab initio calculations. The structural model was based on the transformation of metallic Ni and Cu into Ni-Cu alloy on γ- Al2O3 from experimental data. Structural relaxation and decomposition simulations were performed using Materials Studio 2016 DMol3 with the Local Density Approximation – Vosko-Wilk-Nusair (LDA-VWM) exchange correlation functional, Gaussian double zeta plus polarization function basis set (DNP) at 2x2x1 k-point calculation and orbital cut-off of 3.5 Å, with simulation parameters: T = 1300K, time step = 1.9 fs (78.5 a.u.), simulation time of 0.38 ps, with canonical NVT (constant amount (N), volume (V) and temperature (T)) thermodynamic ensemble and Generalized Gaussian Moment (GGM) thermostat. Simulation data suggest lower C deposition at 1:1 Ni-Cu. Simula

2. BASEMENT CAR PARKS: A DOMICILE OF RADON POLLUTION VALIDATED BY DISCOMFORT INDEX

Authors: AH BU-OLAYAN , BV THOMAS

Abstract: Investigation in the public basement car parks from six Governorates of Kuwait showed the influence of radon concentrations and the probable discomfort caused while parking their cars. Radon concentrations in the public semi-closed car parks distributed in the six Governorate sites were analyzed using Rad7 (Durridge, USA).The peak concentration of radon from the six Kuwait Governorate car parks was relatively higher during the winter season (63.15Bq/m3) than during the summer season (41.73Bq/m3).This validated the influence of relative humidity and temperature, the components of discomfort index (DI). The mean annual absorbed dose rate radon (DRn) and annual effective dose (HE) was observed high when the assessment included the car parks and the surrounding residential apartment and office premises. The DRn (0.02mSv/y) and HE 0.06mSv/y) of radon in the car parks alone indicated radon concentrations below the permissible limits. Statistical assessment indicated the significant differenc

Abstract: Radiotherapy plays an important role in the treatment of cancer patients. As part of clinical workflow, patient has to undergo through diagnostic imaging procedures, which are used to identify the tumor location and size. Enormous amounts of data are generated during this procedure. The volume of medical information is so large and complex that it becomes difficult to mine for relevant information. The Digital Imaging and Communications in Medicine (DICOM) standard is widely used in medicine for storing and transmitting medical information. The DICOM-RT is the extension to DICOM standard, and dedicated to radiotherapy. In this paper, we propose a technique to store clinical relevant features from DICOM files using semantic concepts. The proposed technique defines a novel method to delayer the hierarchy of DICOM-RT for storing the clinical relevant information into triples in Resource Description Framework (RDF) repository. The methodology also proposes different combinations for storin

Authors: ANTONIO GARZON , JUAN L. PEREZ , JULIA PECCI , LIBIA PEREZ , MARINO PALACIOS , ROBERTO SAN JOSE , ROSA M. GONZALEZ

Abstract: The impact of future climate scenarios on building energy consumption for ventilation, heating and cooling was investigated using very high spatial resolution urban meteorological data over Madrid and London areas and considering the Representative Concentration Pathway 4.5 and 8.5 IPCC climate scenarios. To quantify the impact, we use very high resolution urban meteorological dataset produced by a dynamical downscaling process. This paper also presents the modeling system to make a dynamical downscaling process for urban climate information. The outputs of the Community Climate System Model (CCSM) provides future climate scenarios, and its coupling with Weather Research and Forecasting and Chemical (WRF/Chem) model. The output from the WRF/Chem model at 1 km resolution is used to drive a micro-scale computational fluid dynamics model, MICROSYS. The final weather data was used in building energy simulations by EnergyPlus model. Sixteen types of buildings were simulated of each of the t

Authors: AUFA ADEELA ANUAR , NUR AIN YUSOF

Abstract: Mosquito repellent-incorporated fabric softener was produced using geranium oil from Pelargonium Graveolens plant as a potential natural source of repellent agent to provide efficacy against mosquitoes. This paper provides the method of making the mosquito repellentincorporated fabric softener having the geranium oil added during the preparation. 100% cotton fabric was laundered and treated using the fabric softener. The treated samples were tested using the Bioassay Repellence Assessment, WHO Cone Test using Aedes Aegypti mosquito species to ascertain the repellence potential of the fabric softener against mosquitoes. Some physical attributes of the treated fabric, i.e. the fabric weight, fabric stiffness and crease recovery angle, were determined to ensure the main functions of the fabric softener are retained. The Bioassay WHO cone test result showed that the fabric softener incorporated with the geranium oil from the Pelargonium Graveolens plant has the potential to drive away mosq

Authors: MOHAMAD FAIZUL YAHYA , MOHD ROZI AHMAD , NADHIRAH AMRAN

Abstract: Moisture management properties are an important factor that could decide the comfort level of clothing worn by humans. This is largely dependent on the type of fiber and fabric structure of the fabric. In this study, the moisture management properties of untreated and scoured 100% cotton, 100% bamboo and 50/50% bamboo/cotton knitted fabrics were investigated. It was found that the 100% cotton and 100% bamboo fabrics, either untreated or scoured, gave good to excellent overall moisture management capability (OMMC) indicating water penetration fabric with small spreading area. The 50/50% bamboo/cotton fabrics were graded as having poor OMMC which means that fabrics are slow in liquid absorption, drying and spreading of the liquid. It can be said that the moisture management properties depends on the fiber types and ratio of yarn combination.

10. COMPARISON OF PERCENTAGE OF DAYLIGHT FACTOR VALUES (%DF) FROM FIELD WORK TO ALTERNATIVE METHODS OF SIMILAR DERIVATIONS

Authors: ADEL ABDULLAH , SHARIFAH FAIRUZ SYED FADZIL

Abstract: Field work measurement in the East room from previous work were found to be 2.28% with a wall to window ratio (WWR) of 50% and a %DF of 1.23% for a modified WWR of 25%. This paper examines the extent of the field work %DF values compared to the %DF values that could be derived for similar cases while using alternative methods. The alternative methods include Building Research Station (BRS) protractors and three other simulation software including ECOTECT, IES and ReLux. Results found that the %DF differences between field work values and the alternative methods were minimal. This proves that the %DF method is still a very reliable method for daylight assessment

11. DETERMINING SINGLE POINT PERCENTAGE DAYLIGHT FACTOR (%DF) VALUES THROUGH FIELD WORK DATA IN MALAYSIA

Authors: ADEL ABDULLAH , SHARIFAH FAIRUZ SYED FADZIL

Abstract: This paper suggests a way to measure %DF using fieldwork data by taking samples in residential rooms at the University Science Malaysia. The two rooms face east and west for comparison. Two varied window to wall (WWR) and window to floor (WFR) ratios were tested for this experiment. The %DF values calculated from this research were analysed by comparing the east-facing room to the west-facing room and by comparing the different WWR and WFR. The results indicate that given the dynamic and varying sky conditions, east-facing rooms resulted in higher %DF values in both WWR and WFR. It is also found that in Malaysian skies, a 1%DF value is a good estimate for a residential room natural illumination level.

Authors: SITI AMIRA OTHMAN , ZUR AIN AZREEN ZAINUDDIN

Abstract: This review paper describes the immobilization of horseradish peroxidase (HRP) on nanopolyaniline (PANI) by using self-assembly technique. Some chemically synthesized conductive polymers such as PANI were used as support for HRP immobilization. Enzymes immobilized were depend on their properties of immobilize of HRP such as optimum pH, thermal stability and storage stability and all these were investigated. The structure of PANI was characterized by FTIR, FESEM and UV-VIS. The structure of PANI depends on the pH of the phosphate buffer and the type of organic solvent. Thus, the formation of monolayer especially nano-particles of PANI was prepared by using Langmuir-Blodgett technique. The contribution in the development of the biosensor application for hydrogen peroxidase (H2O2) based on the HRP modified electrode was described.

Authors: ALIREZA PIRAHMADIAN , SHAHRUDIN ABDUL RAZAK

Abstract: Adaptive immunity, with its rearranging immunoglobulin and T-cell receptors, has caught most of the attention of current genetic and immunological research and overshadowed the importance of the receptors expressed by cells of the innate immune system. Natural Killer cells have evolved two main receptor systems to carry out their functions, both of them involving activating and inhibitory receptors include members from the Immunoglobulin-like superfamily as well as lectinlike receptors. Killer Immunoglobulin-like receptors (KIR) are polymorphic cell surface molecules present on Natural Killer (NK) cells which recognize classical HLA class I molecules and in doing so provide an alternative means of modulating the immune response to infected or tumoural cells. In this study we did the Separation of Natural killer cells (NK cells) from rat’s blood with the technique of LS column with the help of CD49 markers and Cultured of harvested NK cells in animal cells media (Dulbecco’s Modified Eag

17. EFFICIENCY MEASUREMENT OF TWO-STAGE PROCESSES WITH SHARED INPUTS AND OUTPUTS BY DEA: AN APPLICATION ON MALAYSIAN PALM OIL REFINERIES

Authors: ALI ASHRAFI

Abstract: In recent years, a great number of Data Envelopment Analysis (DEA) studies have focused on Decision Making Units (DMUs) with two-stage structures, where all outputs from the first stage are intermediate products that are applied as the inputs of the second stage. In many situations, some inputs and outputs are shared between two stages. For this type of two-stage process, the conventional two-stage DEA models have some limitations e.g. efficiency formulation and linearizing transformation. In this paper, we introduce a relational DEA model for the two-stage process with shared inputs and outputs that the overall efficiency is illustrated as a convex combination of efficiencies of its two stages. The linearity of DEA models is preserved in our model. A numerical example of Malaysian Palm Oil refineries is used to explain the model.

Authors: INNOCENT NHAPI , SIMON TAKAWIRA MUSERERE , ZVIKOMBORERO HOKO

Abstract: Activated sludge process control is a major challenge to plant operators given the need for correct balance of parameters to achieve plant optimum conditions. A good example is a correct Mixed Liquor Suspended Solids (MLSS) balance necessary to retain the Food to Microbe (F/M) ratio within the desired range. In this regard, mathematical models play an important role in assisting plant process control. Thus, a research on a full scale activated sludge nutrient removal plant was carried out in Harare, Zimbabwe at Firle Sewage Treatment Works (FSTW) Unit 4. The main objective was to investigate opportunities for optimizing nutrient removal through the use of BioWin Simulator. This paper presents the results of calibration, simulation and validation of the BioWin modeling tool for optimum nutrient removal from a study carried out during the period 2012 to 2015 at FSTW. BioWin Simulator is complex because it attempts to simulate simultaneously biological processes of different organisms in

20. GYROSCOPE’S INTERNAL KINETIC ENERGY AND PROPERTIES

Authors: RYSPEK USUBAMATOV

Abstract: Gyroscope devices are primary units for navigation and control systems that have wide application in aviation, in space, on ships and other industries. The main property of the gyroscope device is maintaining the axis of a spinning rotor. This gyroscope peculiarity is represented in terms of gyroscope effects in which mathematical models have been formulated on the law of kinetic energy conservation and a change in an angular momentum. The known gyroscope theories are represented by numerous publications, which analytical approaches cannot give true results. The nature of gyroscope effects is more complex than represented in known publications. Recent investigations in this area have demonstrated that the external torque acting on a gyroscope generates several inertial torques which are interdependent and simultaneous action. The gyroscope internal torques are generated by the action of several inertial forces as well as a change in an angular momentum. Latter one does not play first r
