INTRODUCTION Necrotizing enterocolitis (NEC) is a common in neonatal intensive care unit (NICU) patients; especially in premature and low birth weight ones. Surgery is indicated when there is pneumoperitoneum. Other therapies include conservative observation or primary peritoneal drain (PPD). This study was conceived to evaluate peritoneal tapping, rather than primary peritoneal drain (PPD) as ...

In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. In this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-drai...

We demonstrate an alternative path for achieving high transconductance organic transistors in spite of relatively large source to drain distances. The improvement of the electronic characteristic of such a scheme is equivalent to a 60-fold increase in mobility of the underlying organic semiconductor. The method is based on percolating networks, which we create from a dispersion of individual si...

background and aims: infectious bronchitis virus (ibv) is the etiological agent of infectious bronchitis (ib), which is an acute and highly contagious disease of the respiratory and sometimes the urogenital tracts of chickens. in iran, the disease has been identified in chicken flocks with serological and virus isolation methods. gene 3c (e) encode envelop (small membrane) protein. for envelope...

To meet the gate leakage specifications in the International Technology Roadmap for Semiconductors (ITRS), an intensive search is being conducted for alternative gate stack materials. Most of the studies have focused on basic material properties, but very little effort has been directed towards quantifying and understanding the effect of post metallization annealing (PMA) on the electrical prop...

OBJECTIVE To compare the perioperative results between Transperitoneal Laparoscopic Radical Prostatectomy (T-LRP) and Extraperitoneal Endoscopic Radical Prostatectomy (E-LRP). MATERIAL AND METHOD Retrospective reviews of 125 patients who underwent laparoscopic radical prostatectomy by single surgeon (C.N) for stage T2-T3 adenocarcinoma of the prostate between May 2001 and July 2006 at Siriraj...

Egg envelope or otherwise called zona radiata (ZR) is an acellular area that originates next to oolemma externally. It grows and thickens gradually from oolemma and follicular epithelium both. Microscopic studies on the tissue sections hava shown that during developmental stages of oocytes, ZR could not be observed at stage I (Primary growth stage) in Acipenser persicus. It appeared in stage ...

A 12-week laboratory study was conducted to assess the minimum initial moisture content of compost bulking (envelope) materials necessary to sustain desired heat production and completion of carcass decomposition during emergency composting of swine carcasses. During full-scale field testing of a semi-enclosed emergency composting procedure, first developed and used by the Canadian Food Inspect...

This paper presents both analytical modeling and simulations based on finite element method of Pentacene Thin Film Transistors or Organic Thin Film transistors (PTFTs/OTFTs). Analytical modeling approach is introduced by using conventional transistor equations and finite element method using ATLAS two dimensional numerical device simulators. Both the methods shows a good agreement of output cha...
