nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...

OBJECTIVES To validate externally the performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model and compare this model with other frequently used models in the differentiation between benign and malignant adnexal masses. METHODS In this retrospective diagnostic accuracy study, we assessed data collected prospectively from patients with adnexal pathology who underwent r...

Computing machines are getting superior by the day, especially, in terms of their processor efficiencies and speeds. This enhanced capability of the processors needs to be matched by an appropriate betterment of memory performance, which can be brought about by improving the hit ratio (hit ratio is the total number of cache hits divided by the total number of cache lookups) of cache memory. Thi...

To provide performant access to data from high energy physics experiments such as the Large Hadron Collider (LHC), controlled replication of files among grid sites is required. Dynamic replication in response to jobs may also be useful, and has been investigated using the grid simulator OptorSim. In this paper, results from simulation of the LHC Computing Grid in 2008, in a physics analysis sce...

Earlier research has shown that adaptive routing can help in improving network performance. However, it has not received adequate attention in commercial routers mainly due to the additional hardware complexity, and the perceived cost and performance degradation that may result from this complexity. These concerns can be mitigated if one can design a cost-effective router that can support adapt...

This paper describes the design and use of a synthetic Web proxy workload generator called ProWGen to investigate the sensitivity of Web proxy cache replacement policies to five selected Web workload characteristics. Three representative cache replacement policies are considered in the simulation study: a recency-based policy called Least-Recently-Used (LRU), a frequency-based policy called Lea...

Memory hierarchy is used to compete the processors speed. Cache memory is the fast memory which is used to conduit the speed difference of memory and processor. The access patterns of Level 1 cache (L1) and Level 2 cache (L2) are different, when CPU not gets the desired data in L1 then it accesses L2. Thus the replacement algorithm which works efficiently on L1 may not be as efficient on L2. Si...
