BACKGROUND HIV prevention programmes for truck drivers form part of the HIV control efforts, but systematic data on the outputs and cost of providing such services in India are not readily available for further planning and use of resources. METHODS Detailed cost and output data were collected from written records and interviews for 2005-2006 fiscal year using standardized methods at six samp...

This paper presents an online method for the assessment of the dynamic performance of the chassis frame in a heavy-duty dump truck based on a novel stochastic subspace identification (SSI) method. It introduces the use of an average correlation signal as the input data to conventional SSI methods in order to reduce the noisy and nonstationary contents in the vibration signals from the frame, al...

Abstract A major part of the European Union’s (EU) project Sustainable Intelligent Mining System (SIMS) is investigating development diesel-free/carbon–neutral underground mines in order to ensure sustainable mining future. Replacing diesel machines with electric vehicles hard rock has been widely acknowledged by industry worldwide as a critical step improve working conditions reducing exhaust–...

background: long distance truck drivers (ldtds) and their sexual health risk behaviors have been associated with greater prevalence of sexually transmitted infections (stis), hiv and hepatitis virus transmission. however, there is no information about iranian ldtds' high-risk behaviors. the aim of this investigation was to estimate the prevalence of high-risk behaviors in iranian ldtds. methods...

In this paper, we present an innovative decision support system that simultaneously provides predictive analytics to logistic nodes as well as to collaborating truck companies. Logistic nodes, such as container terminals, container depots or container loading facilities, face heavy workloads through a large number of truck arrivals during peak times. At the same time, truck companies suffer fro...

PROBLEM An average of three workers a year are killed in surface mining operations when a piece of haulage equipment collides with another smaller vehicle or a worker on foot. Another three workers are killed each year when haulage equipment backs over the edge of a dump point or stockpile. Devices to monitor the blind areas of mining equipment are needed to provide a warning to operators when ...

This paper presents a novel approach, referred to as the WordTree design-by-analogy method, for identifying distant-domain analogies as part of the ideation process. The WordTree method derives its effectiveness through a design team’s knowledge and readily available information sources (e.g., patent databases, Google) and does not require specialized computational knowledge bases. A controlled...

This paper presents the design of a low cost voltage controller of a single phase Self-Excited Induction Generator (SEIG). The control scheme is based on the measurement of users load voltage and controlling the dump load power using an Analogue Input Power Controller (AIPC). The controller output varies from 2 -10V and it controls the output AC power going to a resistive dump load. A PI type c...

Mouse thymidylate synthase R209K (a mutation corresponding to R218K in Lactobacillus casei), overexpressed in thymidylate synthase-deficient Escherichia coli strain, was poorly soluble and with only feeble enzyme activity. The mutated protein, incubated with FdUMP and N(5,10)-methylenetetrahydrofolate, did not form a complex stable under conditions of SDS/polyacrylamide gel electrophoresis. The...
