EXTRACTION OF DNA FROM HERBARIUM LEAVES VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionTwo methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA

EXTRACTION OF DNA FROM LEAVES OF VITIS VINIFERA L.
06.00.00 Agricultural sciences
DescriptionExtraction of the DNA from leaves of genus Vitis is a very difficult task, as a grape has a lot of elements, which make difficult to use it in the genetic manipulation. In that article used the methods of extraction of the DNA with silica (SiO2) particles as the absorbent material for getting better quality DNA

MODELS OF NEURONET INFLATION IN RUSSIA
01.00.00 Physical-mathematical sciences
DescriptionThe article’s conclusion is that for adequate and effective inflation modeling in Russia by means of modern neuronet technologies it is necessary to consider tendencies of economic development. For training and forecast, it is necessary to use only those periods of time within the limits of which identical economic tendencies work. The article uses modern tool means, such as neuronet, which is offered to technology, for approximation and forecasting of rates of inflation
