The total reaction cross section of high-energy nucleus-nucleus collision refects the nuclear density profiles colliding nuclei and has been a standard tool to investigate size properties short-lived unstable nuclei. This basis relies on assumption that is strongly absorptive in sense an optical model. However, this property does not hold completely, while incomplete absorption occurs when over...

Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...

This paper deals with the effect of process parameters on the peak load and the energy absorption of the expansion of thin walled tubes using a die. The energy absorption and peak load during the expansion process were calculated for various punch angles (α) and with different expansion ratios (rp/ro) at different temperatures (T) by finite element analysis where rp is the punch outer radius an...

The main objective of the paper is to demonstrate the computer simulation and energy absorption of tapered tubes under impact load. The study of the impact load includes axial compression, bending and torsion. In general, one could rely on the use of finite element analysis to determine the energy absorption capacity of the energy absorbers. This tool is helpful and accuracy. The parametric var...

In this paper, tetragonal chalcopyrite (CIGS) Cu(InxGa1-x)Se2 with x=0, 0.5, 0.8, 1 are synthesized by heating-up method. These nanoparticle structures differ in morphology and absorption properties due to the synthesis temperatures of 250, 255, 260, 265, 270 and 280 ºC, and gallium molar ratio over the total gallium and indium contents. These features are studied using scanning electron m...

Neutrino absorption cross sections for Ga are calculated for all solar neutrino sources with standard energy spectra, and for laboratory sources of Cr and Ar; the calculations include, where appropriate, the thermal energy of fusing solar ions and use improved nuclear and atomic data. The ratio, R , of measured ~in GALLEX and SAGE! to calculated Cr capture rate is R50.9560.07 ~expt!120.03 10.04...

Climatic conditions have a significant impact on the energy consumption of  buildings. Also check the angle of the solar radiation on buildings and controlling the amount of heat absorbed on building shell during the year have significant impact on building energy efficiency. The aim of this study was to investigate the effect of orientation of the building on the energy consumption and to this...

This work shows that optical switching between the spiro (SP) and merocyanine (MC) states of different photochromes specifically labeled to G-actin can be used to rapidly and reversibly modulate specific dipolar interactions within the conjugate. Members of a common spirobenzopyran photochrome and a related spironaphthoxazine that differ only in the locations of their alkylating groups were sel...
