The paper describes the development of austenitic steel with TWIP effect, which is alloyed chromium to increase corrosion resistance. experimental heat this was cast in an melting furnace and subsequently subjected hot cold rolling. After rolling, appropriate recrystallization annealing temperature applied obtain optimal grain size. X-ray diffraction proved that contains a fully structure. anne...

Leaf rolling occurs in some cereal genotypes in response to drought. We identified and made a phenotypic, cytological and physiological analysis of a leaf-rolling genotype (CMH83) of hexaploid triticale (X Triticosecale Wittmack) that exhibited reduced plant height, rolled and narrow leaves. Gliadin electrophoresis of seed protein showed that CMH83 was genetically stable. Sequential Giems...

In this paper, we compare the effect of rolling resistance at the contacts in granular systems composed of disks with the effect of angularity in granular systems composed of regular polygonal particles. For this purpose, we use contact dynamics simulations. By means of a simple shear numerical device, we investigate the mechanical behavior of these materials in the steady state in terms of she...

Platelets and leukocytes are thought to play a leading role in the pathogenesis of many inflammatory conditions. To recruit flowing blood cells to the inflammatory region, it would be necessary for them to interact with vascular endothelial cells. Recently, many reports have indicated the resistance of spontaneous hypertensive rats (SHR) to endotoxic sepsis. Their resistance might be derived fr...

Rolling resistance is the of a wheel that will roll or rotate due to friction between outer surface and track surface. This study aims determine effect tread patterns on coefficient rolling resistance. The tires be used in this are hard compounds with ratio pattern raised by 2 mm tire hardness 79.5 Ha, using pressure variations at 30 Psi, 40 50 Psi. Coefficient value 1.39% 8.05 N. These results...

This article proposes a simple and convenient method for assessing the subject-specific rolling resistance acting on a manual wheelchair, which could be used during the provision of clinical service. This method, based on a simple mathematical equation, is sensitive to both the total mass and its fore-aft distribution, which changes with the subject, wheelchair properties, and adjustments. The ...
