The proposed solar dryer (S / D) has a polycarbonate coating, which is actually a combined dryer. By drying an agricultural products in the proposed apparatus, it is possible to get ecologically pure and high quality food. The "greenhouse effect" in S / D ensures the temperature under the glass is 15-25°C, higher than the ambient temperature. In windy weather, the product to be dried cannot be left in the open air due to strong winds, in this device drying in windy weather occurs no less intensively than in hot weather, although the air temperature in S / D is not high. During wind it is recommended to locate the S / D with the inlet towards the wind. The high drying speed occurs due to the increased convective movement. The wind creates a fan effect both at the inlet S / D and at the outlet - at the end of the pipe. In the proposed installation, it is possible to dry various agricultural products, both in direct sunlight and without them.

Statins are the integral medications for the management of patients with acute coronary syndrome including unstable angina (UA) with multiple pleiotropic effects. However, the influence of statins on the coagulation system is controversial. Our study aimed to explore the effects of atorvastatin and rosuvastatin in high doses on some coagulation parameters (prothrombin pool (PP) and soluble fibrin-monomer complexes (SFMC) concentration) after a 7-days follow-up period in patients with UA. We recruited 50 patients aged 55 to 70 years with progressive UA. Standard therapy according to ESC guidelines 2020 was recommended for all patients. Before treatment onset, they were divided into 2 groups: group A – 26 patients were prescribed atorvastatin, group R – 24 patients with rosuvastatin treatment. The blood samples to analyze the concentration of PP and SFMC were collected twice – before the treatment onset and 7 days after. We revealed significant decrease in PP concentration (p=0,02) and increase in SFMC concentration (p=0,01) in group A patients while there were no significant changes of investigated parameters (p=0,94, p=0,57 respectively) in group R. Additionally, we have noted significant negative correlation between baseline PP concentration and direction of PP changes (r=-0,803, p

The energy supply of the body has an energy price, which is paid, in particular, by the myocardium. This price depends on the circulatory conditions, which can also be affected by iatrogenic factors, such as subarachnoid anesthesia (SA) in the prone position. Decreasing of a vascular tone under the influence of SA requires the myocardium to increase energy consumption to maintain an adequate cardiac index (CI). With a resistive type of circulation, autoregulation of blood circulation may become untenable, that requires artificial maintenance of vascular tone with the α1-adrenomimetics, that also contribute to an increase in energy expenditure by the myocardium. All this makes the assessment of blood flow energy relevant.The aim of the study was to study the effect of SA in the prone position on the energy of circulation.65 patients underwent transpedicular stabilization of 1-2 segments under SA in the prone position have been examined. On the eve of the operation, the prognostic index of hemodynamic instability (PIHI) has been determined by the N. Lysohub’s method. At three stages (the position on the back after performing SA, 5 and 20 minutes after turning on the prone position), kinetic (systolic index, ejection fraction, heart rate and SI), dynamic (effective, or average, AP — APe, central venous pressure, the difference between them — systemic perfusion pressure and specific peripheral vascular resistance) and hemic (blood oxygen content) indicators have been determined. Based on these indicators and the energy potential of oxygen (the energy obtained by glucose oxidation by 1 mol of oxygen), the following energy parameters have been calculated: flow power index (FPI), tissue power consumption index (TPCI), oxygen reserve (OR) and circulatory reserve index (CRI). APe was maintained at least 60 mm Hg during anesthesia by infusion and, if necessary, by administration of the α1- adrenomimetic phenylephrine. Patients have been retrospectively divided into 2 groups: patients of the VF1 group (n = 25) needed phenylephrine administration, and patients of the VF2 group (n = 40) did not need it.The following results have been obtained. The minimum PIHI in the VF1 group was 0.1, which made it possible to expect a high probability of hemodynamic instability, while in the VF2 group it was no higher than 0.05. The integral kinetic parameter CI in the groups did not differ significantly, but the energy consumption and their efficiency between the groups significantly differed. FPI in the VF1 group was significantly lower than in the VF2 group, although TPCI did not differ significantly between the groups. TPCI compliance with tissue needs was determined by OR, which was significantly lower in the VF1 group. The final parameter CRI was significantly lower in the VF1 group, although CI did not differ significantly from the VF2 group level. This indicates energy insufficiency of circulation in patients with a resistive type of circulation against the background of SA in the prone position, so with this type, the presence of which is confirmed by a high PIHI, preference should be given to another type of anesthesia.

The study conducted proves that pelvic tilt is one of the root causes of onychocryptosis. Recovering the correct position of pelvic bones via manual methods restores the symmetrical position of the nail edge in the lateral nail fold of a toe, thus preventing any damage to the soft tissues of the lateral nail fold which is what causes onychocryptosis in the first place. By correcting pelvic bone imbalance via manual methods, we can therefore eliminate onychocryptosis without even touching the affected toe.

The results of the treatment of overweight patients under the ERAS program are presented. When comparing different variants of the intensive care protocol, it is best to add colecalciferol and D-fructose-1,6-diphosphate sodium salt hydrate.An increase in the amount of secretory active adipose tissue in the body is accompanied by a decrease in the bioavailability of vitamin D, a decrease in the level of 25 (OH) D in the blood increases the level of parathyroid hormone. The introduction of a planned surgical profile in overweight patients at the screening stage 10 days before surgery to determine the level of 25 (OH) D in the blood is a key point in deciding the possibility of a perioperative period under the ERAS program. Additional use to its classic protocol of colecalciferol (positive effect on long-term effects and is significant in the prediction process) and sodium D-fructose-1,6-diphosphate hydrate solution (directly affects the effect of rapid recovery after elective surgery) improves the quality of motor activity of patients after operations, increases their adaptive capacity by restoring lost muscle function. The optimized classical algorithm of the ERAS program significantly (p

In this article considers the effectiveness of the impact of sports on the functionality of the cardiovascular system of girls 17-21 years old living within the Podolsk region. The function of the cardiovascular system of girls was evaluated by the ability to recover after termination of work (by the parameters of heart rate). Classes cycling and playing sports (performance of muscle work of which is connected with the mixed mode of power supply) and martial arts (performance of muscular work is associated with anaerobic (lactate) mode of power supply) contribute to improvement the functional possibilities of the cardiovascular system. This is manifested by the acceleration of recovery of heart rate after metered physical loads of 1 watts and 2 watts per 1 kg of body weight. The smallest percentage of person with a slow recovery of heart rate were detected among athletes, volleyball players and representatives of complex coordination sports. These individuals are involved in the performing of physical exercise with anaerobic (alactate) processes of metabolism.

Biodegradation of polymers of spatial structure is complicated at the impact of soil destructive microorganisms and biodegradation requires long time. We have implemented target-oriented synthesis of a polymer to receive linear structure polymers where labile peptide bonds are preserved.To implement target-oriented synthesis of a polymer and to determine optimal conditions for reaction mechanism we studied the process of kinetics and its regularities – reaction temperature, duration, components ratio, concentration, reaction speed constant and activation energy. The Arrhenius factor and succession of introduction of initial components to the reaction medium were computed, catalyst nature and other properties were determined.High effect of prolongation was achieved, when carbamide and formaldehyde molar ratio was 1:1. In this case linear structure polymer is formed where peptide -CH2 – NH – are preserved.The simplified structure of linear polymer is expressed as followed: – HNCONHCH2[ NHCONHCH2 ]n – HNCONHCH2 – .
