Despite 200 years of efforts to regulate safety in this occupation, chimney sweeps have increased mortality from cancer, ischaemic heart disease, and respiratory disease. Mortality and incidence of cancer were examined in a cohort of 5542 Swedish chimney sweeps employed through their national trade union at any time between 1918 and 1980. Previous studies of this cohort found increased risks of...

The practice of Egyptian psychiatrists emigrating to high-income countries is not a recent phenomenon. Egyptian doctors have long travelled in search of training and education and to better their standards of living. The debate continues. What effective measures can be taken to reduce the brain drain, or at least its effect on Egyptian mental health services?

The height of mechanical mixing layer is one of the parameter of the safety analysis report of any industrial (nuclear) facility due to its relation to the dispersion factor of pollutants. It can provide information about lower atmospheric dispersion, which is usually used to study the pollutants released from nuclear facility, risk analysis and emergency planning. Mixing layer height is diffic...

This study was designed to calibrate and evaluate the subsurface drain flow component of the Root Zone Water Quality Model (RZWQM; Version 2.5) for four tillage-systems: chisel plow (CP), moldboard plow (MB), no-tillage (NT), and ridge-tillage (RT). Measured subsurface drain flow data for 1990 was used for model calibration. Main parameters calibrated were lateral saturated hydraulic conductivi...

INTRODUCTION Though surgical drainage is used as a safety measure, it's not without complications. Migration of various drains has been described, but very little literature refers to the migration of peritoneal drain. PRESENTATION OF CASE A 55-year male underwent anterior Gastro-Jejunostomy for inoperable metastatic carcinoma of the Gastric Pylorus. We found the peritoneal drain missing on t...
