BACKGROUND During military escalations emergency departments provide treatment both to victims of conflict-related injuries and to routine admissions. This requires special deployment by the hospitals to optimize utilization of resources. OBJECTIVES To evaluate routine visits to the ED during Operation Cast Lead in Israel in 2008-2009. METHODS We obtained data regarding routine visits to th...
BACKGROUND Biomass burning is an important source of ambient fine particulate air pollution (PM2.5) in many regions of the world. METHODS We conducted a time-stratified case-crossover study of ambient PM2.5 and hospital admissions for myocardial infarction (MI) in three regions of British Columbia, Canada. Daily hospital admission data were collected between 2008 and 2015 and PM2.5 data were ...
Radiotelemetry is used extensively in zoographic studies of wildlife species, including northern bobwhite (Colinus virginianus). These studies assume that radiomarking does not affect survival of marked individuals. However, most researchers implicitly acknowledge that capture, handling, and radiomarking may have short-term deleterious effects on individuals and, therefore, include in analyses ...
The aim of this study was to show the effect of four feeding regimes on thyroid hormones concentrations, growth performance and food coefficient in Rainbow Trout applied through 4 treatments and 3 replications in winter 2006. In this research, samples of rainbow trout with an initial mean weight (SO) 47.19±0.42 used in each rearing unite. Fish were fed twice a day ad libitum as follows: Treatme...
Two photosynthetic periods and photosynthetic photon flux densities (PPFD) were used to study the relationship between the rate of photosynthesis and starch accumulation in vegetative soybean leaves (Merr. cv Amsoy 71). Plants grown in short daily photosynthetic periods (7 hours) had higher rates of CO(2) fixation per unit leaf dry weight and of leaf starch accumulation than plants grown in lon...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
PURPOSE To characterize the temporal integration properties of the emmetropization process, the authors investigated the effects of brief daily interruptions of lens wear on the ocular compensation for negative lenses in infant rhesus monkeys. METHODS Eighteen monkeys wore -3 D lenses binocularly starting from approximately 3 weeks of age. Six of these monkeys wore the lenses continuously. Fo...
After immobilisation of muscle in a shortened position there is a reduction of muscle fibre length due to a loss of serial sarcomeres. Experiments have been carried out to determine whether short, daily periods of stretch prevent sarcomere loss and the resultant loss of range of joint motion. It was found that periods of stretch as short as 1/2 h daily were sufficient not only to prevent loss o...
