The SCI standard describes the interconnection of computing nodes by a ring structure. Although the SCIringlet has the bene t of facilitating small con gurations without requiring switches, there are weaknesses with respect to scalability and fault tolerance. We propose to use a wormhole routed switching fabric, such as the Rcube, as a building block for constructing scalable and fault tolerant...

The potential feasibility of layered double hydroxides for removal of sunset yellow dye FCF from aqueous solution was investigated. The effects of various experimental parameters such as contact time, solution pH, dye concentrations and adsorbent dosage were investigated. The extent of sunset yellow FCF dye removal increased with the increased in contact time and amount of layered double hydrox...

spinal cord injury (sci) is a devastating condition with enormous personal and social costs. to develop preventive strategies, the determination of epidemiological features and causes is required. due to iran's high incidence of road traffic crash (rtc) injuries, epidemiologic data concerning specific causes of sci may assist in reducing this national health dilemma. in a retrospective stu...

polyphenols have been shown to have some of the neuroprotective effects against neurodegenerative diseases. these effects are attributed to a variety of biological activities, including free radical scavenging/antioxidant and anti-inflammatory and anti-apoptotic activities. in this regard, many efforts have been made to study the effects of various well-known dietary polyphenols on spinal cord ...

background: spinal cord injury (sci) occurs most often to young men at the peak of their reproductive health. only 10% of sci men can father children without medical assistance due to potential impairments in ejaculation and sperm quality. objective: the main objective of this experimental study was to evaluate the epididymal necrospermia- sperm death, after chronic sci in rat. materials and me...

objective: spinal cord injury (sci) causes infertility in male patients through erectile dysfunction, ejaculatory dysfunction, semen and hormone abnormalities. oxidative stress (os) is involved in poor semen quality and subsequent infertility in males with sci. the aim of this study is to examine the effects of sci on the level of testosterone hormone. materials and methods: in this experimenta...
