In this paper, the removal of phenol by using aqueous solution in a low pressure reverse osmosis membrane was investigated. The effect of feed pressure, feed concentration, feed flow rate and feed pH on phenol rejection was investigated. The results showed that feed pH is the most affective parameter on the phenol rejection. Rejection of phenol increased with increasing pH from 2 to 10 under th...

UNLABELLED "Human error" in anesthesia can be attributed to misleading information from patient monitors or to the physician's failure to recognize a pattern. A graphic representation of monitored data may provide better support for detection, diagnosis, and treatment. We designed a graphic display to show hemodynamic variables. Twenty anesthesiologists were asked to assume care of a simulated ...

We introduce a new parallel programming paradigm namely synchronous parallel critical sections Such parallel critical sections must be seen in the context of switching between synchronous and asynchronous modes of computation Thread farming allows to gen erate bunches of threads to solve independent subprob lems asynchronously and in parallel Opposed to that synchronous parallel critical sectio...

Large-scale disasters, particularly failures of critical infrastructures, are exceptional situations which cannot be solved with standard countermeasures. The crises are complex and the decision makers face acute time pressure to respond to the disaster. IT based decision support systems provide potential solutions and assist the decision making process. Many decision support systems in emergen...

project scheduling inevitably involves uncertainty. The basic inputs (i.e., time, cost, and resources for each activity) are not deterministic and are affected by various sources of uncertainty. Moreover, there is a causal relationship between these uncertainty sources and project parameters; this causality is not modeled in current state-of-the-art project planning techniques {such as simulati...

Introduction  Mechanical ventilation may be lifesaving intervention,It can be associated with complications,Thus,successful weaning is constitutive.One of the factors which is  important in successful weaning is  method of weaning. It is shown that  weaning is conducted successfully by using Spontaneous Breathing Trial (SBT) through T-piece and pressure support (PS) ventilation.But few studies ...

The concept of critical ambient pressure is introduced in this paper. particle escapes from its trap when the becomes comparable with or smaller than a value, even if motion cooled by one feedback cooling (or cavity cooling) schemes realized so far. may be small that it not limiting factor ground-state cooling, but rates, which are also paper, factors. any rates (corresponding to components mot...
