Different aspects are reviewed of the management of emulsified petroleum products in mechanical engineering industries with reference to the waste problem. Poor quality of make-up water, poor hygienic conditions, inadequate design of feed systems and failure to use a suitable bactericide influence the volume that has to be discarded and then subjected to waste treatment. The inadequacy of the f...

Abstract The problems of providing the population with high-quality water for territories where sources are absent or do not meet hygienic requirements presented. It is shown that there no proper relationship between quality drinking and investments directed modernization treatment transportation technologies. it practically impossible to justify in supply within current tariffs water. possibil...

A wide spectrum of the biological effects of lead and aluminum ions is noted during short-term and long-term oral administration to laboratory animals. The general toxic and gonadotoxic effects of these metals during a short-term experiment appeared to be identical, and the correlation of these effects was preserved during chronic experiments. Lead (0.03 mg/l.) and aluminum (0.5 mg/l.) concentr...

The exceptional flood of the river Odra in July/August 1997 caused severe damage, especially on the Polish side of the Odra valley. An additional 5 km3 of water were discharged during the flood. This represents about a third of the normal annual Odra discharge of 17 km3. Large agricultural and industrial areas were submerged, as well as towns and villages. However, as regards the Odra lagoon an...

Hygienic macro systems, such as Scheme’s, automatically rename variables to prevent unintentional variable capture—in short, they “just work.” Yet hygiene has never been formally presented as a specification rather than an algorithm. According to folklore, the definition of hygienic macro expansion hinges on the preservation of alphaequivalence. But the only known notion of alpha-equivalence fo...

Misalignment of quality incentives along value chains may limit and therefore function as a barrier to smallholder participation in modern chains. This article uses survey administrative data study how individual provided by private actors can help smallholders improve milk quality. By matching farmers on baseline characteristics, I find that increased the compositional quickly after its introd...
