Abstract: Nanofluids have heat transfer more than typical fluids that causes they used in cooling systems and performance their efficiency. They usually supplied by dispersing metallic and oxide nanoparticles in fluids. Heat transfer performance of nanofluid depends on viscosity, thermal conductivity, specific heat and density. Viscosity affects the pressure and the pumping power of fluids. When nanofluids are circulated in a closed loop for transfer of heat in cooling systems, they can affect the thermal conductivity due to the phenomenon of convection. In the present research, an empirical viscosity assessment of nanofluids comprising CuO nanoparticles (NPs) Propylene Glycol-based in different concentrations and various temperatures of nanofluids has been carried out in this paper. For viscosity investigation of nanofluid, CuO NPs dispersed within propylene glycol (PG). CuO nanoparticles suspended in PG with volume fractions ranging from 0.3, 0.7, 1.1, 1.5, 1.9 and 2.3 % were prepared. So viscosity measured by stabinger viscometer (SVM3000) in various temperatures such as 770F=250C, 400C and 500C. It seems that the sample with 0.3 % and temperature of 250C has maximum viscosity and 1.9 % with temperature of 500C shown minimum viscosity. It shows that there is an almost decrease in viscosity of propylene glycol-based nanofluids with increase in CuO nanoparticles concentration. The viscosity results thus obtained are compared with the Einstein’s model. Keywords: nanofluids, propylene glycol, viscosity.

Abstract: The aim of this study was to synthesize silver nanoparticle from the crude extracts of Brucea antidysenterica leaves in order to find possible sources for future novel antibacterial activity in pharmaceutical formulations. Silver nanoparticles were prepared by chemical reduction method and it was confirmed with the help of UV-Vis absorption spectroscopy and compared its antibacterial activity with 80%methanol crude extract. The synthesis of nanoparticles was confirmed by change in colour from yellowish to dark brown. Further, it was confirmed by UV-Vis spectrometer which the biosynthesis of silver nanoparticles. The peak is clearly visible around 438 nm which indicate the reduction of silver ions occurred due to the water-soluble phytochemicals present in the leaf extract. The synthesized silver nanoparticles have strong antibacterial activity against E.coli and S.aureus than standard and 80%methanol extract. A very low concentration of silver nanoparticle (0.008mg/mL) gave antibacterial performance. Applications of Ag nanoparticle based on these finding may lead to valuable discoveries in various fields such as medical devices and antimicrobial systems. Leaf of Brucea antidysenterica can be used as source of silver nanoparticle to prevent diseases associated with antibacterial activity.

Abstract: Natural radionuclides, such as, Uranium (U-238), Thorium (Th-236), Radium (Ra-226) and Potassium (K-40) are present in the soil. In this study the detection of natural radioactive materials in the soil of bauxite mining areas in Kuantan was determined. Soil samples were collected from three different places. Advanced Nuclear Spectroscopy System with UCS 30 Universal Computer Spectrometer Software and High Sensitivity Gamma Spectroscopy Model SE-9764 with WinDas Software were used. Background radiation energy spectra and soil samples were obtained and compared. The spectra obtained by measuring all samples show the similar pattern as recorded from the background radiation measurement. Therefore, this study evidenced the absence of radioactive elements in the collected soil samples of bauxite mining areas. However, results cannot be generalized for all bauxite mining areas of Kuantan district. Keywords: Natural radioactivity, Bauxite, Gamma spectroscopy, Soil.

Abstract: Determining efficient solutions for large scale transportation problems is an important task in operations research. In this paper a transportation algorithm is applied to determine the minimum cost. The algorithm determines the initial Basic Feasible Solution of Transportation problems to minimize the cost. Numerical example are provided to illustrate the proposed algorithm. It can be seen that the proposed algorithm gives a better solution to the given transportation problem. At first the Decision Making Indicators (DMI) are calculated from the difference of the greatest unit cost and the nearest-to-the-greatest unit cost. The least entry of the DMI along the highest DMI is taken as the basic cell. Finally, loads have been imposed on the original TT corresponding to the basic cells of the DMI. Herein the cost minimizing least entries (CMLE) table called Cost Minimizing Small Table (CMST) is formed. So CPU time will become small. Also it discussed how to satisfying the supply and demand restrictions, minimize the total transportation cost. Keywords: IBFS, TT, DMI, CMST.

Abstract: By employing the DMC method, we investigate the performance of eight DFT exchange-correlation functionals for the ground and excited states of some rare-earths. The functionals to which we investigate are CAM-B3LYP, PBELYP, B3PW91, PBEOP, BMK, M06-2X, M06-L, and M06-HF. The present study shows that M06-2X functional with a large fraction of HF exchange is more preferable than M06 for lanthanides; however, the same is not true for actinides. On the other hand, the full HF exchange functional, M06-HF, is not recommended for both lanthanides and actinides. Furthermore, the calculations find that BMK is the best performers for both the ground and excited states of actinides. Our results also suggest not using functionals containing LYP correlation for systems involving lanthanides. Keywords: Diffusion Monte Carlo; Density functional theory; Lanthanides; Actinides.

Abstract: We introduce the term “grey matter” to the mass involved in Special Relativity, similar to our mind, which has no inertia, although it generates energy; this mass, derived from electric charge, is electromagnetic and virtual in nature and assumable by Quantum Theory, but not by Classical Mechanics. The matter itself, ie, that which corresponds to a real or inertial mass, is produced under the strong, weak an electromagnetic interactions, based on coupling constants (charges) and potencials; thus, tangible objects with constant mass acquire the consistency they need to generate inertial forces, in accordance with the laws of Chemistry and Classical Mechanics. The Universe contains two kinds of matter: a) the grey one, which is the only information we have of stars, galaxies and other objects through the radiation we receive and it may also account for the so-called “dark matter”; b) the true matter, originated in stars and responsible for gravitation, whose extremely small intensity (relative to the other three forces) only allows having a similar scope of our Planetary System. The failure in the unification of the Special Relativity with Classical Dynamics, makes the General Theory like a set of definitions and identities, converted into laws by imperative of mathematical rules based on differential geometry (tensors or manifolds), where the curvature of spacetime becomes an “absolute”, pretending generate interaction governing the world as a whole, but supported by some experimental evidence of little or no reliability.

Abstract: The aim of this study is to test and distinguish which of ARIMA and VAR models performs best in forecasting inflation in Rwanda. In order to fulfil this objective observed quarterly data from 2000Q1 to 2015Q1 on economic variables such as the Consumer Price Index, Money Supply, Gross Domestic Product, T-bills Rate and Exchange Rate are used to build models. Box-Jenkins approach is used to build ARIMA model on Consumer Price Index data and it has been found that ARIMA (3, 1, 4) perform better. In VAR analysis Johansen’s Cointegration approach is applied and the results showed that there is long run and short run relationship between dependent variable (inflation) and independent variables. The performance of these models in forecasting inflation is evaluated using Root Mean Squared Errors (RMSE), Mean Absolute Errors (MAE), Mean Absolute Percentage Errors (MAPE) and the results showed that ARIMA (3, 1, 4) perform better than VAR model in forecasting inflation in Rwanda.
