Vanadium-doped magnesium nanostructures are fabricated by an oblique angle co-deposition method and hydrogenated/dehydrogenated for 21 cycles. The effective thermal conductivity and density of the MgH2 nanostructures is measured by using a photothermal system. A multilayer physical model is used to fit the experimental data. Our results show that the effective thermal conductivity of the hydrog...

background and aims. cad/cam systems facilitate the use of zirconia substructure materials for all-ceramic copings. this in vitro study investigated the marginal and internal fit of zirconia copings made with cad/cam system and slip-casting method. materials and methods. sixteen cad/cam made zirconia copings and 16 slip-cast made zirconia copings were fabricated and cemented with glass-ionomer ...

I N B R I E F We are used to thinking of intelligence as largely a matter of genetic inheritance, but that is not the whole picture. What we do aff ects our mental wellbeing: staying physically and mentally active helps us stay sharp as we age. Nevertheless, our personal eff orts to bolster cognitive enhancement cannot forestall all declines in our cognitive performance. What is especially surp...

Prior research indicates that managers’ dark personality traits increase their tendency to engage in disruptive and unethical organizational behaviors including accounting earnings management. Other suggests the prevalence of personalities management may represent an accidental byproduct selecting managers with accompanying desirable attributes fit stereotype a “strong leader.” Our paper posits...

objective: depression is a growing public health problem, which needs more consideration in primary care settings. by focusing primarily on developmental psychology, attachment style is one of the most influential variables on the risk of internalized disorders. although attachment styles have strong effects on emotional aspect of human mental life, emotional turbulence and dysfunction are cons...

A statistical approach was applied to select those models that best fit each individual mitochondrial (mt) protein at different taxonomic levels of metazoans. The existing mitochondrial replacement matrices, MtREV and MtMam, were found to be the best-fit models for the mt-proteins of vertebrates, with the exception of Nd6, at different taxonomic levels. Remarkably, existing mitochondrial matric...

background: gastric cancer is the fourth common malignancy and the second prevalent cause of cancer death in the world. genetic and environmental factors play an important role in the development of this cancer. nutritional and epidemiological studies have indicated that folate status modulates the risk of developing cancer and apoptosis has been reported to play a decisive role in precancerous...

In order to probe the order parameter symmetry of the heavy-fermion superconductor (HFS) CeCoIn5, we employ point-contact spectroscopy, where dynamic conductance spectra are taken from a nano-scale junction between a normal-metal (N) Au tip and a single crystal of CeCoIn5. The point-contact junction (PCJ) is formed on a single crystal surface with two crystallographic orientations, (001) and (1...
