Abstract Taking into account the statistical data gathered in two previously published papers concerning the pollution sources in the production sector, namely Finishing section, various solutions are proposed for wastewater treatment. Bearing in mind the results obtained through the sampling method on different types of water in the urban sanitary sewer system, the conclusion was that the most convenient alternative, besides the source control is the treatment in wastewater treatment plants...

Human nature constantly tends to place personal interest first, to the detriment of general interest. In this respect, tax and duty payers have always attempted to evade payments on their tax liabilities, resorting to various tactics, as they view such compulsory payments as detrimental to their wealth and income. On the other hand, the state seeks to maximise its receipts from taxes, duties, excises etc. In Romania, after 1990, an entire range of anti-tax reactions occurred in the sphere of pub...

This process results in the selection of the species depending on their tolerances (abiotic filter) and their ability to cope with the interactions among species (biotic filter). In this work, the importance of abiotic filters on the structure of benthic macro-invertebrate guilds was evaluated in a hyperalyne transitional wa...
