background: heavy metals (hms) are one of the most important polluting substances emitted to the environment during cement production. tehran cement factory located in the southeastern of tehran, iran, closer to agricultural lands cultivates alfalfa, barley, and maize as feed. the objective of the study was to determine the concentration of hms in agricultural soils. methods: thirty six soil sa...

The effects on the environment and health of the operation of a chromate compounds factory and tanneries in the León valley in central México are discussed. Sampling and analysis of chromium were performed in water, soil, and human urine. Groundwater has been polluted in an area of about 5 km2 by the leaching of a solid factory waste, which results in concentrations up to 50 mg/l of hexavalent ...

Software factory technology and practice -In the USA has recently accelerated rapidly with the boom in the CASE (Computer Aided Software Engineering) market. Concerns about long-range international competitiveness caused most large USA corporations to focus on corporate restructuring to achieve leaner, more adaptive modes of operation. Concerns with Federal deficits caused similar pressures on ...

The whole “package” InnoSteel consists of a group of projects which contain support for product development of innovative companies an...

background: long term exposure to hazards at the work place is injurious to health and usually leads to diseased conditions. the objective of this study was to determine the occupational health problems associated with driving among the professional drivers in sagamu, ogun state, nigeria. methods: this study is a cross‑sectional study. total sample of all the consenting professional drivers in ...

This paper discusses a methodology for quickly investigating problem areas in semiconductor wafer fabrication factories by creating a model for the production area of interest only (as opposed to a model of the complete factory operation). All other factory operations are treated as “black boxes“. Specific assumptions are made to capture the effect of reentrant flow. This approach allows a rapi...

The breeding soundness evaluation (BSE) is a practical method to identify bulls with less than satis­ factory breeding potential. This evalu­ ation should be conducted on every bull at least 30 to 60 days before each breeding season to allow enough time for replacement of deferred or unsatis­ factory bulls. The first step in a BSE is to select a veterinarian in your area who is competent in con...
