The purpose of this study was to examine safety observance when spraying pesticide and pesticide related symptoms among Korean farmers. As a cross-sectional study, a questionnaire survey was conducted in rural communities and an investigation carried out by a structured survey of 135 farmers. The results are as follows: The mean of safety observance when spraying pesticides was 3.05±0.58 (range...

The image of thermal spray splats is difficult to collect due to its high velocity of droplets. Especial in High Velocity Oxy-Fuel (HVOF) process, the process present higher velocity of flame jet correlated to other thermal spray process. The system presents at this article describes a useful splats catching method to obtaining splats during thermal spray deposited. Capabilities and advantages ...

BACKGROUND Rapid population growth in Africa requires an urgent expansion and improvement of housing options. Improving housing presents a promising opportunity for malaria control by reducing indoor exposure to mosquitoes. We measured recent changes in house design in rural Uganda and evaluated their association with malaria in relation to a mass scale-up of control efforts. METHODS This ana...

Tuberculosis of the tonsils is by no means a common condition, Mullin (1923), for example, in analysing 400 tonsillectomies found only 4.25 per cent cases of tuberculous tonsils. The present study is based on 2,477 tonsillectomies in the Madras General Hospital. This series covers a period of five years from January 1928 to December 1932. We, however, feel that this investigation is incomplete ...

Mussel growers in Prince Edward Island (PEI), Canada, currently use high-pressure water spraying (~700 psi) to mortally injure or dislodge invasive tunicates from mussel product and gear. An added benefit of this process may be the stimulation of byssal thread production, leading to improved mussel attachment. This study measured byssal thread abundance and thickness in cultured blue mussel Myt...

Data on the operational efficacy of DDT indoor residual spraying against Phlebotomus argentipes, the vector of kala-azar in India, are scarce. We therefore undertook a study of the impact on kala-azar and its vector of DDT indoor residual spraying in the Varanasi district of eastern Uttar Pradesh. Preliminary results indicate that after two rounds of DDT spraying in one village no P. argentipes...
