OBJECTIVES This study characterises the prevalence of a broad spectrum of sexually transmitted diseases (STDs) (herpes simplex virus 2, syphilis, chlamydia, gonorrhoea), and examines associations between risk factors and infection in men working in Bangladesh's trucking industry. Given the high risk sexual behaviours of truck drivers and helpers in many contexts, as well as the direct health ef...

INTRODUCTION There is very limited knowledge about sexually transmitted infections (STIs) transmission and prevention present amongst high-risk groups such as truck drivers in Pakistan because of lack of awareness and understanding about barrier techniques. OBJECTIVE The aim of this study was to collect and access the data gathered from truck drivers about symptoms of STIs, their attitude tow...

haphazard and inconclusive. There were other methodologic obstacles to be overcome as well, such as tissue hardening, sectioning, and staining, but imprecise experimentation was the great deterrent. Writing of the nineteenth century, that towering medical historian, Max Neuburger (1868-1955), stressed "In its efforts to attain precision, medical science...has achieved a 'rebuilding from the ver...

A National Animal Traction Survey carried out in South Africa in 1994, indicated that a substantial number of commercial as well as small scale farmers are using or would like to use draught horses on their farms. A major draw back for such farmers is the unavailability of suitable animadrawn implements. As a result, although many farmers would like to use draught horses, few do because of the ...

Considering real-time requests and multiple truck–drone delivery modes, we propose an online problem using a truck some drones, which form hybrid collaboration system comprising independent truck-carried drones. this problem, focus on how to schedule the vehicles serve requests, with objective of minimizing time latest vehicle’s return station. First, proved lower bound be 1.5. Second, designed...

in this paper the effect of braking force error on the dynamic behavior of the truck is investigated. in the previous studies concerning the braking force error on the vehicle lateral deviation, to avoid complexity, researchers have assumed that the vehicle velocity during the braking process remains constant. in the present work, based on the realistic assumption that the vehicle velocity woul...
