this text carries out some ideas about exact and p− exact sequences of transformationsemigroups. some theorems like the short five lemma (lemma 1.3 and lemma 2.3) are valid here as inexact sequences of r − modules.

background: intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. dynamic hip screw (dhs) is still considered the gold standard for treating intertrochanteric fractures by many. not many studies compare the dhs with proximal femoral nail (pfn), in type ii intertrochanteric ...

Medical plants have a great value in traditional knowledge related to human health care both used whole plant or consisting in curative remedies. These valuable uses has been led to commercial use of medicinal plants and their derivatives which makes great benefits. Also there is a growing desire to use of completely natural materials as curative drugs around the world. These facts show up a gr...

Recovering an unknown object from the magnitude of its Fourier transform is a phase retrieval problem. Here, we consider much difficult case, where those observed intensity values are incomplete and contaminated by both salt-and-pepper random-valued impulse noise. To take advantage low-rank property within image object, use regularization term which penalizes high weighted nuclear norm patch gr...

BACKGROUND The cis-acting promoter element responsible for epigenetic silencing of retinoic acid receptor responder 1 (RARRES1) by methylation is unclear. Likewise, how aberrant methylation interplays effectors and thus affects breast neoplastic features remains largely unknown. METHODOLOGY/PRINCIPAL FINDINGS We first compared methylation occurring at the sequences (-664~+420) flanking the RA...

The adenovirus late region 1 (L1) represents an example of an alternatively spliced gene where one 5' splice site is spliced to two alternative 3' splice sites, to produce two mRNAs; the 52,55K and IIIa mRNAs, respectively. Accumulation of the L1 mRNAs is temporally regulated during the infectious cycle. Thus, the proximal 3' splice site (52,55K mRNA) is used at all times during the infectious ...

o bjectives : dental caries are common and have a high incidence among populations. radiographs are essential for detecting proximal caries. the best technique should be recognized for accurate detection of caries. the aim of this study was to compare the accuracy of detection of proximal caries using intra oral bitewing, extra oral bitewing, improved interproximal panoramic, improved orthogona...
