Pneumoproteins in sewage workers exposed to sewage dust
PURPOSE The association between exposure to bacteria and endotoxins in sewage dust and the serum concentrations of pneumoproteins in sewage treatment plant workers were studied. METHODS Forty-four workers from eight sewage treatment plants and 38 reference workers participated in the study. Microbial aerosol was collected by personal inhalable samplers. The concentrations of bacteria and endo...
متن کاملSurfers against sewage.
We describe a web server for the accurate mapping of experimental tags in serial analysis of gene expression (SAGE). The core of the server relies on a database of genomic virtual tags built by a recently described method that attempts to reduce the amount of ambiguous assignments for those tags that are not unique in the genome. The method provides a complete annotation of potential virtual SA...
متن کاملSanitary Sewage Lift Stations
The lift station is becoming increasingly common as a component of the sewerage systems of Indiana. Cities and towns that have operated for years without the necessity of a lift station (other than one integral with sewage treatment plant) are finding it necessary to include a lift station in plans for extension of sewers. Those cities and towns which have not yet found it necessary to include ...
متن کاملSewage Pump Impeller Selection
Although the mathematics that define the operation of an impeller can be complex (it is the stuff of Bernoulli and Euler), its purpose is straight forward. An impeller is designed to impart energy to a fluid so that it will flow or, if it is already flowing, undergo some increase in its elevation or pressure. It accomplishes this by increasing the fluid’s velocity as it travels through its vane...
متن کاملAntibiotics Removal in Biological Sewage Treatment Plants
This study investigated the occurrence and removal of 12 antibiotics (ciprofloxacin, enrofloxacin, levofloxacin, norfloxacin, nalidixic acid, azithromycin, clarithromycin, roxithromycin, lincomycin, novobiocin, sulfamethoxazole, trimethoprim) at four sewage treatment plants (STPs): two STPs in Kyoto, Japan and two STPs in Beijing, China. The STPs differed in design and operation conditions, uti...
