It is interesting to find the equivalent resistance between two nodes of an infinite electrical network. In this paper, we consider network that can be described as a series squares whose edges are resistors with $R$ and corresponding vertices joined successively by well. Our major work diagonal base square First, apply techniques balanced bridges symmetry voltages convert each iteration para...

We study the quantum transport through networks of diffusive wires connected to reservoirs in the Landauer-Büttiker formalism. The elements of the conductance matrix are computed by the diagrammatic method. We recover the combination of classical resistances and obtain the weak localization corrections. For arbitrary networks, we show how the Cooperon must be properly weighted over the differen...

High-power operation of AlGaN/GaN highelectron-mobility transistors (HEMTs) requires efficient heat removal through the substrate. GaN composite substrates including high-thermal-conductivity substrates such as SiC and diamond are promising, but these composite substrates require careful attention to thermal resistances at GaN-substrate interfaces. We report on thermal characterization of GaN-o...

This paper discusses the influence and content of Typha Australis fibers on thermal mechanical properties clay composites. The objective is to find a better combination length percentage fibers. will allow have good compromise between properties. results found at end this study are conclusive. Indeed, increase percentages fibres improve but values compressive resistances decrease.

certain potato cultivars such as native potato species (nps) from the andes are known to have resistances to different pests and diseases. some accessions are also interesting from a nutritional and culinary perspective. a collection of 35 nps and 11 old spanish accessions were analysed for streptomyces scabies, rhizoctonia solani and globodera rostochiensis, as well as dry matter, reducing sug...

The legal mandate to mainstream gender equality in Spain’s universities has led the establishment of units and adoption policy plans protocols against sexual harassment. This research looks at how policies have been implemented within what resisting facilitating factors hindered promoted their implementation. These questions are addressed by studying implementation ‘Protocol sexist harassment’ ...

Mycorrhizal soybean (Glycine max L. Merr. var. Harosoy-63) plants have lower resistances to water transport than nonmy-corrhizal plants after 4.5 weeks of growth. Although resistances of whole plants differ by 40%, there were no differences in the resistances of stems plus leaves, indicating that the major effect of the mycorrhizae was to reduce the resistance of the roots. Since the fungitoxic...
