Mass attenuation coefficient is a fundamental parameter of radiation interaction, from which the other radiological parameters like half Value Layer [HVL], tenth Value Layer [TVL], total atomic and electronic cross-sections, mass energy absorption coeffic... see more

This paper presents an investigation on the thermal characteristics of a single-effect absorption chiller subjected to the input steam fluctuation for an air-conditioning purpose. The absorption chiller driven by waste steam is utilized with the total cap... see more

A typical planar structure is the most feasible conceptual design of betavoltaic battery due to its simplicity. The self-absorption of beta source, however, causes a limitation to the geometrical efficiency.  Herein, we tried to investigate the self-... see more

This paper sets out to examine a small absorption chiller that uses the pair LiBr/ H2O with a 4.5 kW nominal capacity, using theoretical modeling and the characteristic equation method. The idea is to compare two ways of simulating and evaluating absorpti... see more

The mass attenuation coefficients of graphene, MWNTs and, SWNTs have been measured for gamma energy range 356 to 1332 keV from the radioactive sources 60Co, 133Ba and 137Cs using a well calibrated gamma ray spectrometer consisting of a 3 ´ ´x 3 ´ ´ NaI(Tl... see more

Enhanced X-ray absorption property of single wall carbon nanotube (SWCNT) through gold (Au) doping (Au@SWCNT) has been studied. Mass attenuation coefficient of SWCNT increased 5.2-fold after Au doping treatment. The use of ethanol in the liquid phase adso... see more

A 42-day feeding trial was conducted on 120, day-old ROSS 308 chicks assigned to 4 (C; E1; E2; E3) groups. The broilers were housed in three-tier digestibility cages (5 broilers/cage) which allowed the daily recording of the feed intake and excreta locate... see more

In this study, we attempted to quantify light absorption by insoluble light-absorbing particles (ILAPs) such as black carbon (BC), organic carbon (OC) and iron oxides in snow using an optical method directly and compared the results with those obtained us... see more

In this work, the problem of hydrodynamic, heat and mass transfer and stability in a salt gradient solar pond has been numerically studied by means of computational fluid dynamics in transient regime. The body of the simulated pond is an enclosure of heig... see more
