Biological monitoring of exposure to benzene in traffic policemen of north India.
Occupational health of traffic policemen employed at six major towns of north India was monitored during these investigations. Traffic controllers face the risk of exposure to benzene present in the ambient air as a component of fuel exhaust. Inhaled benzene is metabolized and excreted as phenol. Our observations on urinary phenol show much higher values than prescribed by ACGIH. Furthermore, s...

در این پژوهش مسئله واگذاری ترافیک را از دید سیستم های دینامیکی فرمول بندی می کنیم.فرض کرده ایم که همه فاکتورهای وابسته در طول زمان ثابت باشند و تعادل کاربر را از طریق فرایند منظم روزبه روز پیگیری کنیم.دینامیک ترافیک توسط یک نگاشت بازگشتی نشان داده می شود که تکامل سیستم در طول زمان را نشان می دهد.پایداری تعادل و دامنه جذب را توسط مطالعه ویژگی های توپولوژیکی تکامل سیستم تجزیه و تحلیل می کنیم.پاید...
BIOLOGICAL MONITORING OF MERCURY EXPOSURE IN DENTISTS OF TEHRAN
In order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). Subject data and pertinent health symptoms were asked via a questionnaire. The results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/L, while 27.2 percent of dentists had levels within normal limits (0-19 µg/...
