The article presents a biological characteristic of
burbots in the waters of Yakutia. We discuss the most
essential features of the ecology of this fish
The results of studies of copperhead (2008-2011) in the Volgograd region are shown, geographical distribution, habitat association, environmental characteristics are examined; morphological characteristics of species in the study territory are given
We have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination
The article presents the data on the chemical elements
content in soils, plant leaves and lichens of three
squares in Rostov-on-Don. The calculation of the total
index of soil contamination by chemical elements finds
that soils of the square are characterized by a low
degree of contamination
The article provides information about phytochemical
investigation, medical and nutritional importance of
fruits of Capparisherbacea L. including
CapparaceaeJuss. family in the area of the Nakhchıvan
Autonomous Republic. Some solvents had been applied,
fruit and leave extracts had been bought. The
purification and identification of content of plant
extracts had been investigated with spectroscopic and
chromotographic methods. The saponins, carotinoids,
chlorophyll pigments and flavonoids had been revealed
in the content of extracts. The extracts have been
acquired from fruits of this species by use of polar and
nonpolar solvents and the composition of extracts have
been studied with different applied methods. The
column and thin layer chromatography carried out in
order to purification of contents and extracts were
fractionation and Rf values were calculated
The features of functioning of the reef modules are studied in the conditions of north and middle parts of the Caspian sea in the district of knocking down of depths. Quantitative descriptions of benthos associations are set in the district of setting of artificial reefs and in their zone of influence. The estimation of efficiency of module constructions is executed. Optimal materials and structural decisions, most suitable for the terms of district of researches are specified
In the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control
This article presents information about the features of biotechnology as the driving force of scientific and technological progress. The national programs of the leading countries of the world, it is one of the priority sectors, reflecting the level of the socio-economic condition of the society. Biotechnology is now successfully solves such vital tasks as providing food, the establishment of effective medicaments, obtaining fuel based on renewable raw materials, maintaining ecological balance, conservation of biological resources of the Earth. The development of agriculture in modern conditions is impossible without agricultural biotechnology. It is directly related to viticulture. Choosing an object of an integrated system (embryos, apical meristem, axillary buds), it is possible to clone plants, i.e. produce plants identical to the original. If the same as the object to use isolated cells or protoplasts, in this case, there will most likely altered versions, creating diversity for the breeder. Genetic engineering – the science of younger, since the establishment of the first chimeric DNA molecule. The origin of genetic engineering is rooted in the development of molecular genetics, biochemistry. These technologies, undoubtedly progressive, but their biological safety is still insufficiently explored and is a danger to all life on Earth. The leading Western powers carried out strict control over the introduction of transgenic crop plants, as they are in agrocenosis new biological risks that may adversely affect the plants, animals and humans. In Russia, as in other countries, have already adopted the law “State regulation of genetic engineering”
This article shows how soil contamination with oil leads to a significant decrease in the values of its biological properties. High levels of induction of the alternating magnetic field intensified oil toxic effects
In the article, the review of the results of the research of blood supply of the thorax of large horned livestock, a pig and a dog is given. Blood supply and outflow of blood from biologically active spots of the thorax are discussed
