in this paper, we consider locally graded groups in which every non-permutable subgroup is soluble of bounded derived length.

Passive cooling of electronics systems requires the use fins and spines. Improved heat transfer enhancements in have been achieved through porosity, magnetic field, functionally graded materials, etc. However, space time-dependent analysis passive device with inherent nonlinearities explorations conditions at tip not fully presented. Therefore, this work presents an application hybrid computati...

This paper presents an overview on applications of HFS-FEM to functionally graded materials. Recent developments on the hybrid fundamental solution (HFS) based finite element model (FEM) of steady-state heat transfer, transient heat conduction, nonlinear heat transfer, and elastic problems of functionally graded materials (FGMs) are described. Formulations for all cases are derived by means of ...

In this paper, the influence of the constituent volume fractions by changing the values of the power-law exponent with uniform pressure on the vibration frequencies of reinforced functionally graded cylindrical shells is studied. The FGM shell with ring is developed in accordance to the volume fraction law from two constituents namely stainless steel and nickel. These constituents are graded th...

A series of 100 patients with rheumatoid arthritis (RA), first seen in the early months of their disease, have now been followed up for 18 years, and 43 have died. Rheumatoid disease directly caused death in 9, and the disease or its treatment contributed to death in 7. These 16 patients were younger at onset and younger at death than the 27 in whom death was unrelated to RA. Of clinical featur...

Functionally graded materials (FGMs) are compositionally gradient materials. They can achieve the controlled distribution of the desired characteristics within the same bulk material. We describe a functionally graded (FG) metal-phosphor adapting the concept of the FGM; copper (Cu) is selected as a metal and Cu- and Cl-doped ZnS (ZnS:Cu,Cl) is selected as a phosphor and FG [Cu]-[ZnS:Cu,Cl] is f...

Studies of semantic dementia, imaging, and repetitive TMS have suggested that the bilateral anterior temporal lobes (ATLs) underpin a modality-invariant representational hub within the semantic system. Questions remain, however, regarding functional specialization across a variety of knowledge domains within the ATL region. We investigated direct evidence for the functional relevance of the sup...
