Percivall Pott (1714-1788) and chimney sweepers' cancer of the scrotum.
including incidentally an excellent account of the toxicology of dinitro-ortho-cresol. Once the reader has mastered this different approach he will find that the authors have considered many aspects of industrial toxicology from the essential angle of their biochemical origin, an approach which must surely form the fundamental basis of this subject in future. At present there is just sufficient...
متن کاملExcess of cancer in Swedish chimney sweeps.
The incidence of cancer was investigated among 5266 Swedish chimney sweeps employed for any period between 1918 and 1980. An analysis of the mortality has been reported earlier and showed an increased number of deaths from coronary heart disease, respiratory diseases, and lung, oesophageal, and liver cancer. Excess risks for cancer of the lung and oesophagus were confirmed in this analysis. Amo...
متن کاملSweepers: Swept deformation defined by gesture
Sweepers is a framework for defining space deformation operations for interactive shape modeling. The artist describes a basic deformation as a path through which a tool is moved. Our tools are simply shapes. So we can use shapes already created as customized tools to make more complex shapes or to simplify the modeling process. When a tool is moved, it causes a deformation of the working shape...
متن کاملBasic Solar Chimney Flow Improvements
Preliminary note This paper deals with the numerical analysis procedure and results of flow simulation through solar chimney. Because of relatively low Reynolds numbers, some aerodynamic improvements could be obtained. The paper links input heat energy with geometry or air flow parameters. Basic solar chimney geometry is carried out and analyzed with CFD application in three dimensional domain....
متن کاملAcute lung function response to dust in street sweepers.
BACKGROUND Sweepers are chronically exposed to dust raised during sweeping. Dust is regarded as the most influential agent and it is perceived as a frequent cause of respiratory system illness and may cause acute and chronic lung function impairment. AIMS The aim of this study was to determine the acute lung function changes in sweepers exposed to dust generated from street sweeping. MATERI...
