MEDICAL-ECOLOGICAL ASPECTS OF RESISTANCE MICROFLORA IN CHILDREN WITH ACUTE INFLAMMATORY DISEASES OF THE UPPER RESPIRATORY TRACT [№ 12 ' 2017]
Inflammatory diseases of the upper respiratory tract bacterial nature of the disease, which most often otolaryngologists in modern conditions are becoming increasingly epidemiological, economic and social significance. The trend in recent years has been the changing epidemiology of causative agents of this disease, the properties of the pathogens, resistance to drugs. Along with this, there are regional differences of indicators of resistance of microorganisms, which complicates the selection of antimicrobial agents in starting empirical therapy of acute rhinosinusitis in children. A monitoring study of the species composition of microflora of nasal cavity showed that, along with the leading (80.3%) etiologically significant representatives of pathogenic flora — gram-positive cocci (mainly Staphylococcus ureus and Staphylococcus haemolyticus), the microflora was represented by gram-negative rods bacteria of the genus Klebsiella (Klebsiella pneumonicae) — 1.6%. Among non-fermenting gram-negative bacteria in 0.8% of cases were allocated to members of the genus Pseudomonas. According to the study, the selected isolates of Staphylococcus haemolyticus were not sensitive to ampicillin/sulbactam in 75% of cases, ceftazidime — 73.3%, the highest activity possessed antimicrobial agents ceftriaxone (87.5%) and azithromycin (89.1% of cases). In turn, Staphylococcus ureus in 54.5% of cases were sensitive to ceftazidime, 45.4% to oxacillin. Observed high sensitivity of the pathogen to erythromycin (100%), gentamycin (100%), ofloxacin and ceftriaxone — 90.9% of cases. The results obtained, taking into account regional differences in the indicators of resistance of microorganisms and their sensitivity to antibiotics, can be used in starting the empirical therapy of acute rhinosinusitis in children.

APPLICATION OF PROBIOTIC PREPARATIONS BASED ON BACILLUS OF THE GENUS BACILLUS IN THE IRON AND ZINC SYSTEM OF DELIVERY IN THE ORGANISM OF LABORATORY ANIMALS [№ 9 ' 2017]
Studies in the field of iron and zinc deficiency are caused by the high prevalence of iron deficiency and deficient zinc states according to official statistics of the Ministry of Health of the Russian Federation. It is known that metals in comparison with other elements have the ability to bioaccumulate. Microorganisms are able to extract and concentrate metals, in particular, this ability is possessed by microorganisms that are part of probiotic preparations based on bacteria of the genus Bacillus.
The results of the study of the possibility of delivering iron and zinc to the organism of laboratory animals using probiotic preparations based on bacteria of the genus Bacillus are presented. The probiotic strains were the living and inactivated bacteria of the genus Bacillus: B.subtilis 534, B.cereus 5832, B.licheniformis 7038 and B.subtilis 7048. The data obtained indicate that in the iron delivery system, the most effective probiotic strains studied are inactivated with B.licheniformis 7038 and B.subtilis 7048 (increase in iron in the skin of laboratory animals by 31.7%, in bone tissue — 80.8%, in muscle tissue — 75.9%). In the zinc delivery system, the B.subtilis strain 534 proved to be the most effective, while the zinc content in the skin of laboratory animals increased by 60%, in bone tissue by 78.5%, and in muscle tissue by 43.6%.

In the iron delivery system, the most effective of the drugs being tested is “Vetom-2”, and the least “Sporobacterin”. In the zinc delivery system, the most effective is “Sporobacterin”, and the least effective is “Bactisubtil”.

OUTLOOK RECYCLING SPENT TYPE ZEOLITE NAX ORENBURG GAS CHEMICAL COMPLEX [№ 10 ' 2015]
NaH type zeolites used in industry for drying and deep fine purification of gases and liquids, for the separation of gaseous and liquid mixtures, separation of a mixture of hydrocarbons in a cryogenic air separation plant. Used zeolites Orenburg gas chemical complex is placed on authorized landfill gas production management and refers to the IV and Vclasses of hazard. Zeolites are unusable production waste. The paper presents experimental data on the reuse of waste zeolites. Laboratory studies were carried out on the basis of a branch of Gubkin Russian State University of Oil and Gas in Orenburg. A variant of asphalt production with the introduction of the grain portion of these zeolites. On the basis of the experiments selected the optimal component composition of the experimental asphalt. A variant of the use of waste zeolites — putting them in the concrete mix as a placeholder. It was found optimal amount of spent zeolite added to the composition of the resulting samples. A technique for obtaining samples of concrete mixtures and their composition. Determine their strength properties, such as water saturation, swelling, tensile strength, and coefficient of frost-grade asphalt and concrete strength. Depending on the strength of the samples revealed the content of the waste in their composition zeolite the possibility of using zeolites in agriculture. The developed technology allows to relieve the landfill and reduce the environmental burden on the region. Implementation of the proposed technologies in production will be accompanied by extra profit.

OPTIMIZATION OF PARAMETERS OF COMPOSITE COVERINGS DRY COMPARTMENTS OF AIRCRAFT BY MEANS OF NASTRAN [№ 9 ' 2015]
The researches devoted to minimization of mass of aircraft will never stop being the actual. Decrease in weight allows to lower costs of production of the aircraft, to reduce the dynamic loadings arising when transporting and in the course of its flight and also to reduce amount of fuel, necessary for flight. The purpose of receiving the covering providing the greatest coefficient of a stock of the general stability and the maximum durability of a compartment on condition of minimization of its weight was set. Researches were conducted by modeling of the intense deformed condition of coverings by means of a method of final elements in Nastran. For research the layered model consisting of variously reinforced layers of composite material of the set thickness was used. As a result of calculation on durability and stability of various coverings it was established that optimum schemes of laying of four-layer coverings are the schemes having the inside layers (the closest to a longitudinal axis of a compartment) reinforced under angles and the external layer reinforced at an angle. Lack of distinction in stability and durability of coverings in case of mutual change of places of the layers reinforced under angles provides possibility of replacement of these two layers with one orthotropic layer. When modeling dry compartments of aircraft the preference needs to be given to the four-layer coverings having the scheme of an arrangement of layers (45, –45, 0, 90). Influence of change of quantity of four-layer packages of layers of a covering on its durability and stability was investigated, thus thickness of a covering was accepted by the invariable. It was established that distributions of tension and the maximum tension arising in coverings are identical, and the coefficient of a stock of the general stability increases with increase in number of packages of layers. And, the essential increase in coefficient of a stock of stability occurs only when using two packages of layers therefore when modeling coverings from bigger quantity of packages of layers it is recommended to use technical and economic calculations.

METHOD OF CALCULATION OF NATURAL FREQUENCY FOR CRANE BEAMS [№ 1 ' 2015]
This article describes a developed method analytical calculation of natural frequencies of suspended overhead cranes taking into account the changes of the middle surface of the bending and restrained torsion. Accounting changes the middle surface leads to the calculation scheme less rigid design and brings it to the real object. The analytical expressions for determining the values of the natural oscillation frequencies of one– and two-span crane beams. Compared the values of natural frequencies obtained by the developed method, with the finite element analysis using APM WinMachine and Autodesk Inventor. It was revealed that the discrepancy between the results of the calculations do not exceed 3% for the flexural vibrations and 10% for torsion, due to the lack of consideration of internal friction. It was found that the frequency of forced oscillations crane beams are quite close to their natural frequency. This allows the use of the resulting technique to eliminate the possibility of resonance in the construction crane beams and their elements.
