Microbial substances introduced into the body of animals increase radio stability and reduce the mortality rate. The greatest significance can be obtained by using vaccines based on bacteria of the intestinal-typhoid group, which in the process of life produce antibacterial substances, enzymes, antigens, entero-and exotoxins, and cytokines with radioprotective properties. The tests revealed a complex mechanism of interaction between bifidobacteria and Escherichia in their joint cultivation. The biomass accumulation of E.coli strain «PL-6» and B.bifidum 1 during co-cultivation depended on the ratio of live bacteria E.coli strain «PL-6» and B.bifidum 1. Microcopy of smears made on days 1-4 from monocultures showed that the grown microbes in morphology corresponded to these cultures. The concentration of microorganisms, determined by tenfold dilution by the above method, was 1x109 CFU/ml - E.coli and 1x107 CFU/ml B.bifidum, with a sowing dose of each type of microbe 1x108 CFU/ml. Microcopy of smears made from a mixture of cultures showed that a dilution of 0,9:1,1-1,0:1,0 is most optimal for co-growing bifidum and Escherichia coli, since with a relatively equal number of monocultures on the 1st day Escherichiae multiply intensely, splitting the components of the Blaurock medium and inhibiting the growth of bifidum, but from the 3rd day B.bifidum begins to prevail, splitting E.coli and assimilating substances cleaved by E.coli.

INFLUENCE OF VARIOUS TYPES OF ORGANIC WASTE OF AGROINDUSTRIAL COMPLEX ON PRODUCTIVITY OF ROW CROPS IN THE CONDITIONS OF THE NIZHNY NOVGOROD REGION
Authors:   Nizhny Novgorod state agricultural Academy, Mikhalev E.V. , Khilov D.D
Published: March 2021

The introduction of unprocessed organic waste into the soil leads to the accumulation of nutrition elements for their subsequent assimilation by plants in the land-use system from the organomineral complexes of the soil, which will significantly increase the yield of agricultural crops. However, for 2- 3 years with constant introduction of "raw" manure, soil degradation occurs. So, with the constant introduction of "fresh" litter will be the oppression of cultivated plants by "osmosis" and the subsequent destruction of their root rot due to its high content of raw litter of pathogenic organisms and high level of Pro-infectious potential, which reduces fungistasis soil, leading to lower yields. The cardinal way out of this situation is to add composted manure to the soil. In addition to increasing the content of organic matter in the soil, including humus. Due to this, there is a decrease in osmosis and phytopathogenic load. The biological activity of the soil when composting will be slightly lower than when applying " raw " manure. However, due to this fact, in the following years, when using complex compost, the soil will contain more organic matter compared to the control. In addition," full "composting reduces "osmosis", kills weed seeds and destroys potentially dangerous pathogens of agricultural crops. Based on the above, it can be assumed that the introduction of new organic fertilizers should have a multi-sided effect on the agronomic properties of the soil, which in the end, with the correct use of complex compost, dramatically increases the yield of crops, including cereals.

The article presents the results of a study of the peculiarities of transformation of soilreclamation processes in agricultural landscapes of the Lower Volga region under the influence of changes in the water balance during irrigation and subsequent cessation of irrigation. The increase of the income part of water balance due to irrigation in an adverse combination of poor drainability, weak filtration capacity waterbearing rocks and mineralization of ground waters leads to the development of adverse processes in soils, like a rise of groundwater and salinization. It is proved that the changes in the water supply from automorphic type to hydromorphic type and the changes in the composition of the soil-absorbing ratio significantly transform the main hydrophysical characteristic and moisture conductivity functions of zonal soils, which are required for forecasting water and salt regimes of soils. It is proved that the nature of changes in the salt regime of long-irrigated soils degraded as a result of secondary salinization after being removed from agricultural use is determined by the drainage of territories. It is established that self-reclamation of soils of saline fallow areas occurs if drainage ensures the exclusion of groundwater participation in the water regime of the root layer, which is important to take into account for the involvement of abandoned areas in agriculture.

It is shown that the value of the average radius of friction surfaces of friction discs can be used as a variation parameter when the feedback gain value is automatically adjusted. It was found that the average radius of the friction surfaces of the friction discs as a parameter of variation in the adaptive friction clutches are possible, according to design-layout considerations in a limited range of changes of values of friction coefficient. It is proved that using the value of the radius of the circle on which the sensitive elements of the control unit, as a parameter regulating the coupling is possible in a very limited range of changes of values of the coefficient of friction, since there is a directly proportional relationship of the first parameter from the second.

Features of the velocity structure of the mantle under the Precambrian structures on the example of the Indian platform (according to seismic tomography)

Published: March 2021

The paper presents additional data, approaching to understanding the driving forces in the formation of geological structures and the development of the Indian platform. The results of seismic tomography are attracted here and their analysis is presented. A 3-dimensional P-velocity model of the mantle of the Indian platform was obtained according to the Taylor approximation method developed by V. Geyko. The undeniable advantages of the method are independence from the initial approximation (reference model) and the best approximation of nonlinearity. According to the data, the mantle under the Indian platform is influenced by both plumes and fluid systems. The influence of plumes is observed in the form of low-velocity subvertical exits from the lower mantle to the transition zone; fluids — in the form of interbedding of high and low velocity anomalies from the lower mantle (or from the transition zone of the upper mantle) to the upper mantle. An analysis is presented of both general velocity structure of the platform mantle and the velocity structure of the mantle under individual cratons (Bandelkand, Singhbum, Bastar and Darvar), the totality of which forms the Indian platform and the trap provinces. At lower velocity, an area is distinguished in the mantle that corresponds to the surface of the Narmada-Son lineament moving into the Central Indian Tectonic Zone. The mantle high-velocity structures under the Deccan trap province, together with their spreading area in the transitional zone of the mantle, subdivide the platform into two parts at depths of 375 km. Areas in the mantle with inclined layers were identified and analyzed: under the cratons Bandelkand and Singbum, the Rajmahal traps and the northern border of the Deccan traps. According to the model, an area bordering the Himalayas is well distinguished in the mantle. It is shown how, when the Indian platform collides with the Eurasian margin, the upper mantle stratifies into plates capable of independent motions, including subduction.

Complete correction of Class II malocclusion in an adult patient is not an easy task. In a case with large skeletal discrepancy, orthognathic surgery is the treatment of choice. However, in case of slight or borderline discrepancy, other treatment options are available, such as tooth extractions and miniscrews. Intermediate cases can also be treated with Class II correctors and elastics. This clinical report presents the orthodontic treatment of a 25-year-old female patient with Class II malocclusion. Clinically, the maxilla was well positioned, and the mandible was slightly retruded. The patient presented vestibularized upper incisors, well-positioned lower incisors and opted for a more aesthetically attractive orthodontic appliance. The treatment plan included teeth leveling and aligning in both arches, Class II correction, establishment of Class I molar and canine relationships, correction of overjet and overbite, midline correction, and improvement of facial and dental aesthetics. The orthodontic treatment consisted of removable Invisalign aligners and Class II elastics.

The aim of this pilot study was to test the hypothesis that temporary anchoring devices (TADs) made of 316L steel are more resistant to corrosion even in fluorine environment than DATs manufactured in addition to titanium alloys, for this Potentiostat electrochemical measurements were performed. Materials and Methods: Four pieces of each material were tested in each test set, an application of Fusayama artificial saliva was used as an electrolytic solution in this study of in vitro corrosion, without fluorine in its composition and in a second moment with 1500ppM of fluorine in its composition. In the test, a cathodic polarization was performed by increasing this voltage for 5 minutes or until the corrosion pins were obtained. In artificial saliva containing up to 1500ppmF- this test was repeated with new samples of each material in artificial saliva solution without fluorine. Results: The results of the induction current scale were inserted into OriginPro8 software for making value graphs. As there was a small number of samples, in order not to violate the study’s reliability no statistical test was performed. Among all metal alloys currently used the Ti6Al4V alloy showed good resistance to corrosion in artificial saliva. However, the corrosion of these alloys occurs in contact with high fluorine concentration, unlike 316L steel alloy, which in addition to corrosion makes surface passivation.
