background: in the steel industry, coke-fueled furnaces are used for smelting iron ore to produce cast iron are considered as sources of annoying noise.this study aims to evaluate the noise pollution blast furnace and sound source characteristics in order to present noise control measures in the steel industry. methods: measurement of noise level and its frequency analysis was performed using s...

Toluene is known to be the most popular solvent for industrial use,1,2) and attention has been paid on the possibility of biological monitoring of toluene exposure by urinalysis for metabolites such as hippuric acid and o-creso1.3-5) In a previous study6) on possible ethnic difference in toluene metabolism, it was disclosed that Chinese toluene workers excrete less hippuric acid in urine than t...

In Thailand and in many parts of the world, the annoyances and potential health hazards of mosquitoes1 have led to the development of many devices designed to kill them.2 The electric fly-swatter (Yongtong,Yongtong Electronics Co, Ltd, China) is thought by many to be a safe antimosquito device that is used widely for killing mosquitoes in tropical countries (Figure 1). It is free of toxic chemi...

is well-known in the Operational Research community for his path-breaking contributions to graph theory. He received several awards for his scientific achievements, including the EURO Gold Medal (1989) and the Euler Prize (1995, jointly with R.L. Graham). The name of Claude Berge is likely to remain in history for several other reasons. For instance he was an expert in the Asmat art from New-Gu...

Decades from now, when we fully understand the biologic basis for the clinical heterogeneity of prostate cancer, we will think of the current era as the Golden Age of Prostate Nomograms. Driven by the paucity of randomized data to guide treatment decisions, particularly in localized disease, nomograms have proliferated. Currently, there are more than 40 published prostate cancer nomograms to he...

In 1972 a total of 112 workers exposed to toluene diisocyanate (TDI) were examined for acute pulmonary function changes during a work shift on the first day of the working week. A dose-response relationship was demonstrated for the acute effects of TDI in this population. The cohort was restudied in 1974 to determine whether there was excessive loss of pulmonary function, and if so, whether the...

In 1967 two cohorts of 343 men each were formed and matched with respect to age, district of birth, and similarity of work. One cohort comprised viscose rayon workers with at least five years' exposure to carbon disulphide during any period between 1942 and 1967, and the other cohort consisted of workers from a paper-mill with no such exposure. The concentrations of carbon disulphide and hydrog...

Y pull into the hospital parking lot just before dawn — one of the first cars in, one of the last out. As a first-year resident, you make up in hours what you lack in experience. You speedwalk to the hospital’s back entrance through the January fog. You wonder if you left the iron on in your apartment. No matter how often you iron and bleach your white coat, it never looks or feels clean. You n...
