This article presents a brief overview of the research performed at the Human Factors Division of The University of Michigan Transportation Research Institute between 1977 and 1986. The focus of the research has been on human factors (ergonomics) aspects of road safety. Specifically, the research has dealt with the following issues: vehicle headlighting, vehicle rear lighting and signalling, ve...
Studies carried out in Moscow residents have revealed that the prevalence of chronic toxoplasmosis is very close to those in countries of Eastern and Central Europe. Our findings also demonstrated a statistically significant relationship between the rate of traffic accidents and the seroprevalence of chronic toxoplasmosis in drivers who were held responsible for accidents. The latter was 2.37 t...
The empirical basis for legislation to limit cell phones while driving is addressed. A comprehensive meta-analysis of the effects of cell phones on driving performance was performed. A total of 33 studies collected through 2007 that met inclusion criteria yielded 94 effect size estimates, with a total sample size of approximately 2000 participants. The dependent variables of reaction time, late...
background and aims: sexually transmitted infections (stis) are of major concern to clinicians and researchers in the field of reproductive medicine. many sti pathogens cause incurable and often fatal diseases, and have been transmitted through insemination procedures. the role of herpes simplex virus in male infertility has been investigated using the sensitive methods. the aim of this study w...
In earlier work, a driver model incorporating sensory dynamics was identified from driving simulator experiments involving random disturbances, target paths and linear vehicle dynamics. the present paper, are extended to include transient discrete nonlinear The predictions of compared with measurements experiments. Simulator motion is found have significant beneficial effect on drivers' respons...
car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...
purpose the purpose of the present study was to evaluate the ergogenic effect of caffeine ingestion on mood state, simple reaction time, and muscle power during the wingate test recorded in the morning on elite judoists. methods twelve elite judoists (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ±6.57 m) participated in this study. mood states, simple reaction time, and mus...
هدف: لوسمی لنفوسیتی مزمن یکی از انواع سرطان های خون است که با تکثیر بیش ازحد سلول های b همراه می باشد. این بیماری به طور تقریبی در مردان بالای 50 سال شایع تر است . cll با نقص آپوپتوز در سلول های b همراه است. هدف ما در این مطالعه بررسی بیان پروتئین survivin به عنوان پروتئین مهارکننده آپوپتوز در سلول های تک هسته ای خون محیطی بیماران cll و افراد نرمال تحت تأثیر داروی بربرین در محیط in vitro است. م...
background: dna isolation procedure can significantly influence the quantification of dna by real time pcr specially when cell free dna (cfdna) is the subject. to assess the extraction efficiency, linearity of the extraction yield, presence of co-purified inhibitors and to avoid problems with fragment size relevant to cfdna, development of appropriate external dna control (edc) is challenging. ...
conclusions according to this research and prevalence of hhv-6 in children, evaluation of csf (detecting the hhv-6 dna by pcr) is recommended in patients younger than 13 months with possible encephalitis. results from a total of 114 patients, hhv-6 was detected in 10 (8.8%), 90% of which were boys with mean age 7.7 months and median of 7.5 months. no significant differences were found in clinic...
