When implementing the tasks of controlling technological processes, finding optimal control actions, and creating algorithms that implement modes it is necessary to present criterion optimality in form a goal function, extremum which best meets purpose this object expressed as - Relevant technical economic indicators. The should be an integral indicator reflects main aspects production. Profit ...

The host-mediated assay was initially conceived as a system for determining the mutagenic potential of mammalian metabolites of foreign compounds for bacteria (1). In practice, a genetically defined indicator microorganism is injected into the peritoneal cavity of mice which are then administered the substance under test, either orally or parenterally. After a specified time -usually 3 hr-the m...

Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination of the source of pollution. The use ...

We assessed short-term ecological and potential human health effects of wastewater treatment plant (WTP) effluent by measuring delta 15N per thousand and microbial concentrations in oysters and suspended particulate matter (SPM). We also tested male-specific bacteriophage (MSB) as an alternative to fecal coliforms, to assess potential influence of wastewater contamination on shellfish. WTP effl...

Persistent microorganisms in endodontically treated teeth produce volatile sulfur compounds (VSC) such as methyl mercaptan, hydrogen sulfide, and thioether. In this retrospective study, we evaluated the ex vivo immune response of peripheral blood mononuclear cells to sulfur compounds in 354 patients with systemic diseases. These systemic findings are correlated with semiquantitative values of a...

The release of quality, safe, and effective non-sterile drugs needs to exclude the presence objectionable microorganisms, which include microorganisms potentially involved in product degradation, or considered as poor hygiene indicator during manufacturing, causing adverse effect on patient's health. In this paper, a method allowing objective verifiable evaluations has been investigated through...

Water erosion leads to the loss of soil, nutrients, organic matter, disruption soil structure, reduction moisture capacity, biodiversity, and is most significant degradation process when growing agricultural crops on sloping terrain. Soil microorganisms are basis functioning ecosystems, circulation substances, soil-forming processes formation structure. Microbiological indicators, such as numbe...
