0740-7475/01/$10.00 © 2001 IEEE March–April 2001 THE ACTIVITY OF SEVERAL COMPONENTS in a computing system is event-driven. For example, the activity of display servers, communication interfaces, and user interface functions is triggered by external events, and it is often interleaved with long, idle periods. An intuitive way to reduce average power dissipated by the whole system consists of shu...

The present research was designed to explore the anxiolytic-like activity of a novel 5-HT3 receptor antagonist (60) in experimental mouse models of anxiety. The anxiolytic activity of '6o' at (1 and 2 mg/kg, ip) was evaluated in mice by using a battery of behavioural tests of anxiety such as elevated plus maze (EPM), light/dark aversion test, hole board (HB) and open field test (OFT) with diaze...

It is notoriously difficult to measure the causal impact of foreign aid on the economy. The “micro-macro paradox” (Paul Mosley 1986) renders it impossible to add up the effects of individual aid projects, since foreign aid is fungible. Thus, researchers are left to conduct cross-country analyses to capture the effect of aid on economic growth and other outcomes net of the recipient governments’...

Several dietary alternatives to feed withdrawal have been proposed to induce a molt in laying hens. This study compared the behavior of laying hens on an alfalfa crumble diet (ALC) to hens that were either on a conventional layer diet (FF) or hens that had feed withdrawn (FW) during a 9-d trial. Each treatment consisted of 24 hens (3 hens per battery cage), and treatment began after a 2-week ac...

In this paper we present Open Battery, a tool for collecting data on mobile phone battery usage, describe the data we have collected so far and make some observations. We then introduce the fluid queue model which we hope may prove a useful tool in future work to describe mobile phone battery traces. 1998 ACM Subject Classification D.4.8 Queueing theory

Ingestion of batteries by children became more frequent in recent years, due to the increasing accessibility of electronic toys and devices to children. We report a fatal evolution of battery ingestion in a 2-month-old boy.Lithium battery ingestion is a serious condition with high risk of life-threatening complications in childhood and it can be fatal especially in extreme age, under 6 months. ...

BACKGROUND Chewing fresh leaves of the khat plant (Catha edulis forsk) is a deep rooted and widespread habit in East Africa and the Middle East. Although a body of knowledge exists about the adverse effects of khat on health, data are sparse with regard to the consequences of long-term khat chewing in resulting schizophrenic like symptoms. METHODS A crude extract of khat at different doses (1...

Today's society relies on energy storage a day-to-day basis, e.g. match production and demand from renewable sources, power variety of electronics, enable emerging technologies. As result, vast range technologies has emerged in the last decades. Among them, rechargeable Zn–Air batteries have held great promises for long time. However, severe challenges related to reversible O2 reactions poor cy...

since time immemorial, iranian women have played a pivotal role in agriculture, the largest industry contributing to rural livelihoods. hence, the present study was conducted in tafresh area of iran to examine factors influencing participation of rural women in mixed farming activities in 1999.this was a descriptive- correlation research project in which a total number of 300 rural women were s...
