The sub-surface damage in ground and subsequently annealed alumina/silicon carbide nanocomposite has been studied by analysis of the x-ray diffraction line width as a function of incidence angle. Bragg peak broadening fell as the depth of penetration of the x-ray beam increased. Despite substantial anisotropy in the uniform compressional strain in the surface of the ground material, no signific...

In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar  systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , p...

Students’ residence halls have been studied repeatedly during the last decades from various perspectives (eg satisfaction). However, our knowledge is very limited in terms of students’ emotions towards various residence hall interior and exterior spaces. Besides, very little study exists on the impact of homelike furniture on students’ emotions. The question driving this research is whether the...

The Modified Newtonian Dynamics (MOND) has been formulated as a modification of the Poisson equation for the Newtonian gravitational field. This theory generically predicts a violation of the strong version of the equivalence principle, and as a result the gravitational dynamics of a system depends on the external gravitational field in which the system is embedded. This so-called external fiel...

Abstract In this work, structural parameters of lanthanum cobaltites doped with cerium atomic concentration 1%, 3%, and 5 %, synthesized using the sol-gel method considering calcination temperature 900 °C, were estimated from modeling X-ray diffraction patterns samples. Modeling experimental is carried out Rietveld refinement implemented Fullprof-Suite program. Estimation crystallite sizes obta...

I do not propose this evening to delve into the age-old argument concerning the discoverer of anesthesia. It is doubtful if any here assembled have, to any very great extent, witnessed surgery without anesthesia, yet only 100 years ago the screams of agony issuing from the operating room would have chilled the blood of the hardiest among us. The important point of this contribution is not which...

Pristine and chromium-doped ZnO nanowires were prepared following the traditional co-precipitation method. X-ray diffraction data identified a pure wurtzite hexagonal crystal structure characteristic for ZnO, irrespective of doping level. The particle size, as deduced form Williamson–Hall plots, was found to be 45–55 nm all samples. Scanning electron microscopy revealed clear morphology doped s...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...
