    The areas referred to the areas of sulfate karst are related to the areas of exclusive distribution of gypsum and anhydrite karst, as well as joint occurrence with carbonate rocks and salts. Based on the field study data, generalization of archive materials and publications, as well as the results of monitoring of exogenous geological processes carried out by the authors of the article, the data on sulfate karst of the Perm Territory not updated since the 90s of the last century were analyzed. This made it possible to clarify the boundaries of the previously identified areas of sulfate karst in the Perm region.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ ΠΊ Ρ€Π°ΠΉΠΎΠ½Π°ΠΌ ΡΡƒΠ»ΡŒΡ„Π°Ρ‚Π½ΠΎΠ³ΠΎ карста отнСсСны Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ, Π³Π΄Π΅ закарстованы Ρ‚ΠΎΠ»ΡŒΠΊΠΎ гипсы ΠΈ Π°Π½Π³ΠΈΠ΄Ρ€ΠΈΡ‚Ρ‹, Π° Ρ‚Π°ΠΊΠΆΠ΅ совмСстно с ΠΊΠ°Ρ€Π±ΠΎΠ½Π°Ρ‚Π½Ρ‹ΠΌΠΈ ΠΏΠΎΡ€ΠΎΠ΄Π°ΠΌΠΈ ΠΈ солями.

    Microorganisms are widespread in soils of different genesis and can have a significant effect on their properties. The influence of the vital activity of aboriginal bacteria of different physiological groups on the mineral and chemical composition of clay soil was investigated using methods of X-ray diffraction spectroscopy, X-ray fluorescence spectroscopy, and electron microscopic analyzes. The activation of the vital activity of the soil microflora led both to the destruction of rock-forming minerals and to the new formation of minerals - calcite and iron-containing minerals. During electron microscopic studies, mineral new formations were recorded in soil samples. Newly-formed connections between soil microaggregates were also observed.ΠœΠΈΠΊΡ€ΠΎΠΎΡ€Π³Π°Π½ΠΈΠ·ΠΌΡ‹ ΡˆΠΈΡ€ΠΎΠΊΠΎ распространСны Π² Π³Ρ€ΡƒΠ½Ρ‚Π°Ρ… Ρ€Π°Π·Π½ΠΎΠ³ΠΎ гСнСзиса ΠΈ ΠΌΠΎΠ³ΡƒΡ‚ ΠΎΠΊΠ°Π·Ρ‹Π²Π°Ρ‚ΡŒ Π·Π½Π°Ρ‡ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ΅ влияниС Π½Π° ΠΈΡ… свойства.

    The priority in the oil industry is to reduce the technogenic load on environmental components. Modern technologies allow minimizing the negative impact on water bodies, soils, vegetation, etc. However, the development of effective technical solutions aimed at purification of underground water from oil products is still in progress. There are mechanical, physical-chemical, and biological methods of oil pollution control. Each method has advantages and limitations and can be used in different situations. The technology of groundwater treatment based on biotechnological method and dosed oxygen supply is proposed. The recommended solution can be used as an independent environmental protection measure or in addition to existing ones.ΠŸΡ€ΠΈΠΎΡ€ΠΈΡ‚Π΅Ρ‚ΠΎΠΌ Π² нСфтяной ΠΏΡ€ΠΎΠΌΡ‹ΡˆΠ»Π΅Π½Π½ΠΎΡΡ‚ΠΈ являСтся сниТСниС Ρ‚Π΅Ρ…Π½ΠΎΠ³Π΅Π½Π½ΠΎΠΉ Π½Π°Π³Ρ€ΡƒΠ·ΠΊΠΈ Π½Π° ΠΊΠΎΠΌΠΏΠΎΠ½Π΅Π½Ρ‚Ρ‹ ΠΎΠΊΡ€ΡƒΠΆΠ°ΡŽΡ‰Π΅ΠΉ срСды.

    Research of weight and linear wear from resource indicators of cultivator paws hardened by combined method

    The article presents the results of theoretical and experimental studies of weight and linear wear from resource indicators of cultivator paws hardened by the combined method. It is established that in order to achieve an increased resource of cultivator legs, world manufacturers use special alloying materials, design features and technological methods of hardening, namely heat treatment, application of wear-resistant materials. The most commonly used methods for strengthening the working surfaces of parts are conventional hardening of medium-carbon, highcarbon and alloy steels. The hardness of the metal can be obtained in the range of 45 HRC for steel 45 and up to 65 HRC for steel 65G and alloy steels. To determine the change in the geometric parameters of the blades of cultivator legs during production tests recorded linear wear, weight wear and the radius of rounding of the cutting edge of the working bodies with an operating time of 8, 23, 42 and 54 ha. According to the results of linear wear of the wings of experimental cultivator paws during production tests, the materials that provide the best performance against abrasive wear were determined. As a result of the analysis of cultivator paws with a yield of 54 ha, it was found that the working bodies do not have visible damage and extreme wear and are suitable for further use. At the same time, measurements showed that the amount of wear on the width of the blade is 5.3–11.9 mm

    Background. Clear-cell renal-cell carcinoma (CCRCC) is the most common histological type of cancer of this localization. Changes in 16 genes were identified as significant in carcinogenesis of CCRCC. After VHL suppressor gene, PBRM1 gene is the second by frequency of genetic abnormalities in CCRCC and it is mutated in 40β€”50 % cases of CCRCC.The study objectiveis to analyze the effect of abnormalities in PBRM1 protein expression on survival of patients with CCRCC.Materials and methods. The study included 137patients with newly diagnosed and histologically confirmed CCRCC. For all study participant, detailed medical history and questionnaire data were acquired. Prior to treatment, blood samples and tumor tissue removed during surgery were obtainedfrom all patients. All patients are annually followed up for current information on their life status, disease dynamics, treatment. Minimalfollow-up time is 22 months, maximal is 128 months, mean is 61.8 months, median is 48 months. Immunohistochemical (IHC) testing of PBRM1 expression was performed using standard technique with polyclonal rabbit antibodies PB1[N1N2] N-term (GeneTex 100781) with 1:50 dilution, DAB staining. Normally, protein product of the wild type PBRM1 gene is functioning and can be detected in the nucleus. Absence of nuclear expression of PBRM1 points to genetic or epigenetic abnormalities.Results.Renal cancer-specific survival is significantly lower in patients without expression of the PRBM1 protein in tumor cells. The longest 5- (84 %) and 10-year (84 %) survival was observed in patients with diffuse nuclear expression of the PBRM1 protein. Difference in survival of these patients compared to patients without PRBM1 protein expression is statistically significant (p = 0.004). We have performed an analysis of the association between survival of patients with CCRCC andfocal nuclear PBRM1 expression. In these patients, survival is lower than in patients with diffuse expression but higher than in patients without nuclear expression of PBRM1 (p = 0.02). Cytoplasmic expression of PBRM1 doesn’t affect survival.Conclusion.The obtained results point to prognostic value of PBRM1 gene activity which is abnormal in almost half of all CCRCC cases. IHC testing is an appropriate, reliable and affordable method for determination of PBRM1 protein expression and therefore can be used in practice. Favorable course and prognosis in patients with stage Iβ€”II CCRCC and preserved nuclear expression of the PBRM1 protein should be noted: 5-year survival for these patients is 100 %. This observation is crucial for making decisions on treatment of these patients.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.
