All factors of soil formation can be divided into random ones, which the researcher cannot control when studying soils and ground cover, and non-random ones, which can be studied in detail assessing their contribution to the formation of soil of a particular taxonomic rank. The random soil-forming factors include cryogenic, fluvial, anthropogenic, migratory, denudation, erosion, and solifluction, while the non-random factors comprise climatogenic, biogenic (mainly phytogenic), lithogenic, and chronogenic ones. It is shown that an essential element of randomness is found in the course of erosion processes. However, the established significant methodology for predicting the magnitude of soil erosion and assessing the likelihood of expected damage from soil erosion makes it possible to minimize this random factor.

1200 patients with rosacea, including 525 (43.8%) – with erythematous-telangiectatic subtype were observed during 6 years. An innovative pathogenetic method of treatment of this subtype of rosacea which includes administration of 1% hyaluronic acid in particularly active areas and use of 15% azelic acid in the form of peeling is recognized efficient.

Over the past seven years, the use of long-acting forms of antipsychotic medication has significantly increased in Russia. Specifically, in Moscow, from 2016 to 2021, the proportion of prescribed injectable long-acting antipsychotics had increased more than sevenfold (from 3% to 23%). Studies have shown that the correct selection of target groups for such therapy can reduce the frequency of relapses requiring hospitalization, lower the costs of inpatient care, and shift the focus of therapy from multiple drug administrations to psychosocial work. This study was aimed at evaluating changes over time in psychosocial functioning, as well as clinical and psychopathological manifestations, in patients with schizophrenia during early remission and while on therapy with different forms of paliperidone: oral paliperidone (OP), paliperidone palmitate administered once monthly (PP1M), and paliperidone palmitate administered once every three months (PP3M). The observational study included 155 patients: 54 patients who had been treated with another second-generation antipsychotic received OP, 50 patients who had been treated with another antipsychotic received PP1M injections, and 51 patients who had been in remission for four months after treatment with PP1M received PP3M. The duration of the follow-up period was 12 months. Assessment of personal and social functioning was conducted five times: before the start of treatment, and 3, 6, 9, and 12 months later. Treatment in all groups led to a statistically significant reduction in the severity of positive symptoms (p <0.001). Hallucinations proved more susceptible to therapy (p <0.001), while persistent delusions showed greater treatment resistance. Significantly more patients in the PP1M and PP3M groups had completed the entire program (n=24; 48.0%, and n=30; 58.8%, respectively) compared to the OP group (n=11; 20.4%). The PP3M group demonstrated the highest treatment adherence, with the largest number of patients completing the study, and a similar rate of exacerbations or inadequate efficacy compared to the other groups. Treatment with different forms of paliperidone provides a roughly equal pace reduction in the severity of schizophrenia, including positive and negative symptoms. The PP3M group had better adherence and the highest number of patients who fully completed the study.

The article presents the results of correlation analysis of budget and actual cost data reflecting fleet operational expenses groups and fleet performance quality data.All data is converted to uniform arrays where each element indicates the yearly value of vessel's performance.The initial data comes from corporate accounting and management software of world's leading tanker company having a fleet of more than 100 vessels for the period of 5 years.The correlation analysis concludes with unpredicted expenses impact to the quality of management processes and further necessity to allocate such expenses in OPEX to improve on cost analysis logic, provide justified methods of cost optimization and form rational approach toward asset insurance policy.

Introduction. In recent years, diarrheal syndrome is the most common clinically significant negative effect of the antibiotic therapy (ABT), which constitutes a first-priority medical and social problem. The prescription of any antibiotic for any duration of treatment may cause a potential risk of developing antibiotic-associated diarrhea (AAD). In that regard, there is a need for the systematization of the main pathogenetic aspects of the deveopment of AAD and the rationale for the use of probiotics to prevent its development and treatment. Aim. To conduct a comparative evaluation of the efficacy, adherence and tolerability of a synbiotic Floriosa containing Bifidobacterium lactis Bl-04, Lactobacillus acidophilus La-14, Lactobacillus rhamnosus Lr-32, inulin, B vitamins, and an eubiotic Bifiform containing Enterococcus faecium, Bifidobacterium longum for the prevention of the development of AAD during and after the use of ABT in inpatients. Materials and methods. A total of 60 patients, which was used for the ABT in the hospital settings, were included in the study: the 1st group (30 patients) received a synbiotic, the 2nd group (30 patients) received an eubiotic. The efficacy of the preventive administration of drugs was assessed by Day 12 and 28 of the therapy. The methods included the patients’ assessment of the efficacy and satisfaction with treatment, an assay of short-chain fatty acids (SCFAs) in feces via gas-liquid chromatography and a Clostridium difficile Toxin A + B rapid test. Results. No cases of AAD were detected in both groups. The study drugs were comparable in terms of their efficacy assessment by the doctor and patients. A trend towards a higher assessment of the therapeutic effect and satisfaction with synbiotic therapy was observed. Changes in the absolute and relative content of SCFAs in the patients’ feces from the baseline level were established. More pronounced positive changes in the quantitative and qualitative composition of acids due to the treatment were identified in the patients who received the synbiotic and had more than 3 risk factors. Conclusions. The synbiotic Floriosa and probiotic Bifiform are effective drugs to prevent AAD. The synbiotic has advantages in terms of the overall assessment of the efficacy of the treatment and patient satisfaction, provides a pronounced protective effect on the intestinal microbiocenosis status during and after the ABT (as evidenced by the changes in SCFAs level in the feces), can be the drug of choice for the prevention of AAD, including AAD associated with C. difficile in individuals with more than 3 risk factors for the development of AAD.

Introduction. From the analysis of hop dryers of different systems and designs follows the prospect of hop drying by complex influence of the energy of the electromagnetic field of ultrahigh frequency and convective heat. Aim of the Article. The article aims at developing a small-sized microwave convective hop dryer with justified parameters for intensive drying technology of freshly harvested hops. Materials and Methods. Taking into account the justified criteria for the design of a hop dryer and the analysis of existing resonators, there was proposed a methodology for the development of a hop dryer with an energy supply in an electromagnetic field, including requirements for structural design, operational and economic indicators, and technology. The electrodynamic parameters of the resonator were investigated according to the CST Studio 2017 program. Results. The dielectric parameters of hops are theoretically investigated and functional dependences on humidity at a frequency of 2,450 MHz are obtained. The dynamics of hop heating is investigated when its dielectric loss factor changes during the action of an ultrahigh frequency electromagnetic field. There has been developed a design and technological scheme of a radio-hermetic microwave convective hop dryer of continuous flow action with tiered resonators for low-power agricultural enterprises. Resonators are arranged in tiers in the screening cylindrical housing: the first and third resonators are hemispherical, and the middle one is made in the form of an ellipsoid to ensure a high electric field strength. The transportation of raw materials takes place by rotating the discs in a gentle mode. Discussion and Conclusion. The expected specific energy costs of a hop dryer with a capacity of 12–13 kg/h at the microwave generator power of 4.0 kW for drying freshly harvested hops with a humidity of 76–82% to a humidity of 11–14% are 0.30–0.33 kWh/kg. The required electric field voltage of 2 kV/cm in all three resonators is provided, therefore, disinfection of raw materials occurs at a temperature of 65–70°C for 5–6 minutes of stay in three resonators. The intensity of moisture release from hop cones during endogenous convective heating increases 5–6 times compared to the convective drying method. The introduction of microwave drying technology using a convective method of evaporation and removal of moisture from the drying chamber reduces the duration of the process, saves valuable components of cones for brewing.
