BACKGROUND This research examines the specific contribution of occupation and work organization conditions to alcohol use and misuse. It is based on a social-action model that takes into account agent personality, structures of daily life, and macro social structures. METHODS Data come from a representative sample of 10,155 workers in Quebec, Canada. Multinomial regression models corrected fo...

A bacteriophage with a B-3 morphology was detected by electron microscopy in a spirochete isolated from the tick Ixodes dammini. It has a 40- to 50-nm elongated head and a tail 50 to 70 nm in length. It appears devoid of collars or kite-tail structure. The spirochete has been identified as the causative agent of Lyme disease.

background & objectives: tumor diathesis (td) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. it is found in the background of smears of invasive carcinoma but not in all cases. the aim of present study was to determine the prevalence of td in cervicovaginal smears from patients with uterine cervix carcinoma. methods: cytological smears and histologi...

A Riemann surface X $X$ is said to be of parabolic type if it does not support a Green's function. Equivalently, the geodesic flow on unit tangent bundle (equipped with hyperbolic metric) ergodic. Given arbitrary topological and pants decomposition , we obtain sufficient conditions for parabolicity in terms Fenchel–Nielsen parameters decomposition. In particular, initiate study effect twist par...

This research determined the accuracy and precision of Global Positioning System (GPS) enabled devices as a potential tool to automate recording onfarm grazing events, which can be used indicate productivity paddocks (with number grazings per year), or, when combined with other farm data, estimate nergy harvested. Static tests were initially conducted determine devices’ (location error) (Circul...

abstract background: cervical cancer is the most common female genital tract malignancy and is the major cause of death from gynecologic cancer worldwide. the majority of cervical cancers develop through a series of gradual, precancerous lesions. screening asymptomatic women with regular pap smears allows diagnosis of the readily treatable preinvasive phase. we performed this study to determine...

The use of electric shock collars for training dogs is the subject of considerable controversy. Supporters claim that they are a reliable means of eliminating self-rewarding behaviour and that they can be used over greater distances and with less risk of stress and injury than mechanical devices, such as choke chains. Opponents cite the risk of incorrect or abusive use and temptation to use ele...
