Accurate control of the defectivity of silicon crystals and wafers is a subject of immense importance to both the silicon and IC industries. Exploding costs of wafer development and production as well as the processing of 300mm wafers means that predictive defect engineering is now, more than ever a requirement for both industries. There is little scope any more for iterative approaches to thes...

In February 2006 the Department of Health introduced a new home oxygen service with the aim of improving the assessment of patients on oxygen and allowing access to newer technologies such as ambulatory oxygen. Oxygen is provided following completion of a home oxygen order form and is allocated a predetermined tariff according to the delivery device and usage. In South East Essex there are curr...

In the treatment of left-sided pulmonary interstitial emphysema (PIE) in a 23-week neonate, we used two ventilatory strategies: selective bronchial intubation from day 10 to 15 and neurally adjusted ventilatory assist (NAVA) from day 18 to 26. We compared the effects and adverse effects of these two strategies. On selective bronchial intubation, desaturation was frequent. Fentanyl infusion was ...

in this research, amount of evaporation and transpiration and water requirement of wheat plant for marvdasht town (representation station: zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using cropwat software. at the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...

OBJECTIVE To evaluate whether N-acetylcysteine (NAC) infusion during the first week of life reduces the risk of death or bronchopulmonary dysplasia (BPD) in infants with extremely low birth weight. Study design In a Nordic multicenter, double-blind trial, infants (n=391) weighing 500 to 999 g and on ventilator or nasal continuous positive airway pressure were randomized before the age of 36 hou...

The response of a cell to integrated stresses was investigated using environmental and/or genetic perturbations that disrupted labile iron homeostasis and increased oxidative stress. The effects of the perturbations were monitored as nutritional requirements, and were traced to specific enzymic targets. A yggX gshA cyaY mutant strain required exogenous thiamine and methionine for growth. The th...

BACKGROUND Hypothermia has been shown to decrease the requirement for inhaled anesthetics in animals, but information in humans is limited. METHODS Thirty-three unpremedicated children with congenital left-to-right shunt heart diseases undergoing open heart surgeries were assigned to one of three groups, with nasopharyngeal temperatures at the time of skin incision of 37, 34, or 31 degrees C....

Handler and Dann (1) suggested that nicotinamide is methylated in viva by methionine and excreted in the urine as N’-methylnicotinamide (NMeN). Perlzweig, Bernheim, and Bernheim (2) demonstrated that NMeN is formed in vitro by rat liver slices. The amounts formed were quite small and the maintenance of aerobic conditions and of cellular integrity was essential; furthermore, the addition of meth...
