The effect of some elements of cultivation in stubble on the glycine max performance
Статья научная
In the irrigation conditions of Azerbaijan, the cultivation of Glycine max in stubble fields after harvesting the barley crop along with spring sowing is also economically very important. Sowing in stubble fields makes it possible to obtain additional grain yield and fodder from a single area, and to use reclamation facilities efficiently. At this time, the soil is provided with organic matter for autumn planting, and at the same time salinization is prevented, soil erosion and weed control issues are fully resolved. Cultivation of stubble field crops in large farms increases the possibilities of more efficient use of labor force, irrigation networks, agricultural machinery and equipment. During the conducted research, different results were obtained regarding the effect of different irrigation regimes and fertilizer rates on soybean grain yield. The resulting productivity depended on the plant coverage factor, leaf surface area, changes in wet and dry biomass. The smallest indicator of the yield was 10.0 centners in the variant with soil moisture of 60% before irrigation, and the highest indicator was 25.8 cwt/ha in the variant of the fertilizer rate calculated when the soil moisture was 80%, which is the same as the yield obtained from the autumn sowing of barley of the previous year (39 cwt/ha) together, it is equal to the yield of 67.9 cwt/ha from 1 hectare of land in one year.

Pneumothorax is a pathological condition characterized by the accumulation of air in the pleural cavity, which leads to loss of negative pressure and collapse of the lung. Traditionally, pneumothorax is divided into traumatic and spontaneous, if in the first case the cause is clear, then in the second case, the diagnosis is sometimes difficult. Particular interest to thoracic physicians is spontaneous pneumothorax (SP), which often develops as a result of rupture of a bulla or bleb. Drainage of the pleural cavity is an effective method of treatment, it allows to stop respiratory failure and straighten the lung in the shortest possible time. The problem remains the high recurrence rate, which, according to the literature, ranges from 20 to 40% after the first episode of pneumothorax. Describe the main causes of pneumothorax. Describe the possibility of using chemical pleurodesis (CP) to prevent relapse. Evaluation the efficacy and safety of CP with iodpovidone. The study was made on the basis of the clinic named after I.K. Akhunbaev National Hospital of the Ministry of Health of the Kyrgyz Republic in the Department of Thoracic Surgery. The study included 115 patients with pneumothorax of various etiologies who were treated in the department from September 2015 to February 2023. The control group included 62 patients, here traditional treatment was carried out by drainage of the pleural cavity. The number of people in the test group was 53, here, after complete expansion of the lung, a CP procedure was performed in order to prevent recurrence. If the patient underwent only drainage of the pleural cavity, then the recurrence rate was compared. If the patient underwent thoracotomy with bullectomy, then the frequency of postoperative air leaking was assessed. The safety of the technique was assessed by the main indicators of hemodynamics, temperature and pain response. CP with iodpovidone after drainage of the pleural cavity, as well as as the final stage of open thoracotomy, turned out to be 100% effective in preventing recurrences, as well as postoperative air leaking. Statistical processing showed the safety of CP with iodpovidone. CP with iodpovidone can be successfully used as a prevention of relapse, as well as the prevention of postoperative air leakage. The positive effect was in 100% of cases with minimal side effects.

The soil condition on the slopes used for the cocoa crops has been analyzed. The investigated territory lies in the equatorial plains of South America at the Pacific Coast. The field investigations and the soil samples were taken in the cocoa crops zones. The sites with 3° and 8° inclination angle of slopes were chosen for the analysis. It was found that the higher inclination angle provokes more intensive soil degradation processes and the organic content loss. The organic matter content range in the plow layer decreases from 9.74% to 3.26%. The main degradation factor is the erosion, namely, the sheet erosion of the surface soil. The linear erosion forms are insignificant. The slopes with no more than 3° inclination angle are charachterised by less organic content loss caused by the sheet erosion and appear to be more suitable for the cocoa crops in the investigated zone.

The grape skins and seed polyphenolic extracts
Статья научная
The paper dwells on identification of phenolic compounds and anthocyanins from newly-squeezed grape skins and seed ethanol extracts of Zeibeli and Izabela color grape varieties cultivated in viticulture-winemaking micro-zone of western Georgia, by combined gas chromatography mass-spectrometry, and their determination by method of high-pressure liquid chromatography, but antioxidant activity has been assessed by DPPH method. For the experiment, we used newly-squeezed grape skins and seed without drying, mechanical and thermal treatment. Total phenolic compounds content in grape skins and seed ethanol extracts of Zeibeli variety (>423 mg/100 ml) was greater than in grape skins and seed extracts of Izabela variety (>394.2 mg/100 ml). The same results have been registered when assessing antioxidant activity of extracts. In particular, in the conditions of the same dissolution of extracts, grape skins and seed ethanol extracts of Zeibeli variety had higher antioxidant activity (up to 67-79,4%) than grape skins and seed extracts of Izabela variety (49.5-63.9%). Studies have shown that total phenols and anthocyanins quantitative content correlates with antioxidant activity of extracts. The polyphenolic contents and the antioxidant activity of the skins and pulps of different grape cultivars were estimated using HPLC and DPPH antioxidant assay, respectively. The phenolics and flavonoids identified were quercetin, kaempferol, caffeic acid, p-coumaric acid, cinnamic acid, and (-)-epicatechin. The total phenolic contents were found to be the highest in the grape skin of Flouxa (> 400 mg/100 g), followed by Campbell Early and Tamnara (> 300 mg/100 g), and then by Red Globe and Ruby Seedless (> 250 mg/100 g), and the total phenolic content was the lowest in Italia and Delaware (
