Research ArticleOpen accessIn the abstractBeef Productivity of Limousine Cattle at Stable KeepingIrina Vlasova, Inna Ventsova, Alexander Vostroilov et al.The regularities of the post-embryonic development of farm animals have been studied by numerous researchers. Their ontogenesis is a result of the complex interaction of animal genotype with those conditions of the external environment in which their hereditary basis is realized. In Russia, the stable keeping system of the cattle is highly relevant as many farms do not have large … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 23 Oct 2020 · 6,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and Oil Contamination by Biological IndicatorsSergey Ilyich Kolesnikov, Natalya Aleksandrovna Petrova, Kamil Shagidullovich Kazeev et al.Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 5 Aug 2016 · 7,888 accessesView PDFCite
Review ArticleOpen accessIn the abstractAnalysis of Benzo[a]Pyrene Contamination from an Long-Term Contaminated SoilSvetlana Sushkova, Tatiana Minkina, Abdulmalik Batukaev et al.Analysis of benzo[a]pyrene contamination from an aged contaminated chernozemic, meadow-chernozemic and alluvial soils under the effect of aerotechnogenic emissions from the Novocherkassk regional power plant have been revealed on the basis of annual monitoring studies from 2008 to 2012. A new ecologically clean highly-effective express-method of subcritical water extraction has been developed for determination of benzo[a]pyrene from soils of the … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 16 Nov 2015 · 7,873 accessesView PDFCite
