Abstract:Nanostructured Tantalum (Ta) thin films were deposited by plasma assisted chemical vapor deposition (PACVD) at duty cycles of 17%, 25%, and 33%. FESEM and MTT assay indicated that the Ta film deposited at duty cycle of 25% provides the best surface biocompatibility because of its flawless and uniform structure. Furthermore, [...] Read more.

Abstract:There is interest in the study and control of heat affected zone (HAZ) of the weld junctions, which is often regarded as the weakest point of the joints. In the present work, experimental and numerical analyses are used to characterize extension and microstructure of HAZ in friction stir welding (FSW) of 7075 Al alloy (AA) [...] Read more.

Abstract:Background: Low back pain is neither a disease nor a diagnostic entity of any sort. The term refers to pain in an area of the anatomy afflicted so often that it has become a paradigm of responses to external and internal stimuli. The prevalence of low back pain among hospital workers varies between different countries 39% i [...] Read more.

Abstract:The experimentally found small heating of the neutrons after transmission through thin foils can be explained by violation of energy conservation because of finite energy width of the neutron wave packet. The part of the wave packet subcritically transmitted through a foil has energy distribution higher than that of the inc [...] Read more.

Abstract:Propagation and static distribution of light on noncircular orbits are modelled. The space where light embodies is determined with kinematics, such that the perpendicular velocity of the 'material'-space described as a noncircular orbit, is harmonic with amplitude fwre. Light propagation to discrete orbits may occur with a [...] Read more.
