Ιn medium voltage cables, the stress control layers play an important part in controlling the electric field distribution around the medium voltage underground cable terminations. Underground cable accessories, used in medium voltage cable systems, need a stress control tube in order to maintain and control the insulation level which is designed for long life times. The term “electrical stress control” refers to the cable termination analysis of optimizing the electrical stress in the area of insulation shield cutback to reduce the electrical field concentration at this point in order to reduc

Abstract Abstract 1001 Introduction: SCT occurs in 8% of African Americans and is not commonly associated with clinical disease. Nonetheless, the United States Armed Forces has reported that SCT conveys a 30-fold risk of sudden cardiac arrest and a 200-fold risk from exertional rhabdomyolysis. In fact, rhabdomyolysis in athletes with SCT has been the principal cause of death in NCAA football players in the last decade, leading to recently mandated SCT testing in all Division-1 players. In SCT, RBC sickle only under extreme conditions and with slow kinetics. Therefore, rhabdomyolysis most likel

Duplex α + β’ brasses are widely used in drinking water distribution systems for tube fittings, valves, and ancillaries because they are low cost, easy to fabricate, and exhibit high mechanical strength. However, depending on application conditions and alloy composition, they may undergo dealloying and stress corrosion cracking. In this research, three different brass types, two leaded (CW617N and CW602N) alloys and one lead-free brass (CW724R), were investigated to assess their corrosion behavior and susceptibility to stress corrosion cracking (SCC) in simulated drinking water (SDW) solutions

Abstract Abstract 899 Sickle cell disease (SCD) results from mutations in the β chain of hemoglobin and is associated with a complex pathophysiological process that involves endothelial activation, inflammation and oxidative stress. Several clinical aspects of SCD such as pulmonary hypertension, moyamoya vasculopathy, proliferative retinopathy and leg ulcers suggest the involvement of an unbalanced angiogenesis. Plasma levels of vascular endothelial growth factor, placenta growth factor, angiopoietin-1 and angiopoietin-2 are reportedly elevated in SCD, although the effects of these alterations

Abstract Background: Heme oxygenase-1 (HO-1) is highly inducible in vitro and in vivo and appears to confer protection to cells and tissues from oxidative stress and inflammation. Marked oxidative stress and vascular inflammation are hallmarks of sickle cell disease (SCD). We have previously shown that enhanced expression of HO-1 inhibits vascular inflammation and hypoxia-induced vaso-occlusion in murine models of SCD. To further these observations, we constructed transgene forms of rat HO-1 for gene therapy in murine models of SCD. The high degree of interspecies sequence conservation makes e

This may cause or contribute to adverse outcomes. The best way to prevent and treat malnutrition and optimize nutritional status in these patients, remains unknown.

Tube flaring process involves a conical tool of a certain length which is displaced to get an end flared tube, which is utilized to form a tight seal between pipes or tubes. Tube flaring refers to a kind of forging which is often a cold working operation. The tube forming process is widely used in several industries to form condenser pipes, car seat structures, exhaust piping, etc. Thin-walled tubes were used in automobiles to reduce the total weight for better performance. A conical tool is used for tube end forming in which the tool is moved into the tube known as conventional tube flaring.
