A prospective observational cohort study to assess rates of and risk factors for tuberculin skin test (TST) conversion among health care workers (HCWs) was conducted at an urban hospital located in a high tuberculosis-incidence area in 1994-1998. All hospital employees undergoing required testing every 6 months were included. A total of 69 (1.2%) of 5773 susceptible employees had a documented T...
Joint estimation of gene conversion rates and mean conversion tract lengths from population SNP data
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
The aim of this guidance paper of the European Psychiatric Association is to provide evidence-based recommendations on the early detection of a clinical high risk (CHR) for psychosis in patients with mental problems. To this aim, we conducted a meta-analysis of studies reporting on conversion rates to psychosis in non-overlapping samples meeting any at least any one of the main CHR criteria: ul...
Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...
supplementary feed exogenous enzymes have improved the growth rates of various food animals. in thisresearch, the effect of endofeed w, a multienzyme feed supplement, was investigated on the growth of carp.accordingly, 134 fish (33.1 ± 0.8 g) were randomly allocated to 4 experimental groups. during the first stageof the experiment (10 days), groups 1-3 received 1, 2 and 3 g endofeed w per kg di...

The road environment can affect driver speed choice through influencing both the driver’s perception of their current speed, and the speed that they think is appropriate for the road. These influences and their effects on speed can therefore affect crash rates. This report reviews the influence of various factors within the road environment, including the geometry of the road, the roadside envi...
