Women’s experience of divorce. Acta biomedica scientifica

The article is devoted to the problem of studying the experience of women going through the situation of divorce at different stages of the divorce and post-divorce period.Methods. The study was carried out at the intersection of idiographic and nomothetic approaches. At the first stage, the specifics of the experience of experiencing divorce in the online space are described, revealed through an interpretive-phenomenological analysis of the content of a closed Internet forum (n = 297). On the second – the specifics of emotional perception, cognitive assessment and coping with the situation of divorce, depending on the post-divorce experience (n = 50).Results. The experience of divorce by women is accompanied by ambivalent emotions, activates the understanding of the situation and coping with it. Online communication is an effective strategy focused on getting support, self-change, designing the future, allowing you to experience a sense of community in a life situation while maintaining psychological safety. The assessment of the divorce situation and coping strategies are specific: women who have gone through a divorce less than 3 years ago are more likely to seek social support; from 3 to 10 years – prefer the strategy of “flight-avoidance”; more than 10 years ago – “positive revaluation”. Conclusion. The experience of women experiencing the situation of divorce, including emotional, cognitive and conative components, is specific depending on the stage of the divorce and post-divorce period. An effective mechanism for shaping the experience of experiencing a divorce is network communication in a closed group of people who have similar problems

Влияние минимизации обработки на баланс углерода в почве в лесостепи новосибирского Приобья

The study aimed to assess the carbon balance in leached chernozem when used in a long-term field experiment in 2 variants: with annual ploughing to a depth of 25 – 27 cm and surface treatment by 6 – 8 cm. In the experiment, spring wheat was grown using intensive technology in a crop rotation, pure fallow - wheat - wheat. The variants of the experiment differed in the number of plant residues: straw was removed from half of the fields, and on the other half, it was planted and crushed into the soil after harvesting. The authors estimated the carbon balance based on the element’s input into the ground with plant residues (straw and roots) and its losses in the form of CO2  from the soil’s organic matter during the growing season. The total loss of С–СО2 for the period May – September was calculated based on the average daily rate of production of СО2 , which was determined in the field of pure fallow once a week by the absorption method. Minimization, the transition from ploughing to surface tillage, did not significantly impact the average annual wheat yield (2.49 – 2.60 t/ha) and the number of plant residues (1670 – 1818 kg C/ha of arable land). Also, between these treatment backgrounds, no significant differences were found in the average annual mineralization of organic matter and the carbon balance in the soil. These indicators depended only on the amount of plant matter (straw and roots) entering the ground. The poor credit of carbon in the land (-752 kg C/ha of arable land) was registered when straw was alienated from the field. When it was left on the field, the balance of the element became much more favourable (-88 kg C/ha of arable land), approaching a deficit-free state. The authors concluded that a carbon balance close to a deficit-free one was ensured, regardless of the primary tillage with an average annual wheat yield in a 3-field grain-fallow crop rotation of about 2.5 t/ha of grain and the incorporation of the entire non-marketable part of the crop into the soil in the leached chernozem.Цель исследования заключалась в оценке баланса углерода в черноземе выщелоченном при использовании его в многолетнем полевом опыте в двух вариантах: при ежегодной вспашке на глубину 25–27 см и поверхностной обработке на 6–8 см. В опыте выращивали яровую пшеницу по интенсивной технологии в севообороте «чистый пар – пшеница – пшеница». Варианты опыта различались количеством растительных остатков: с половины полей солому удаляли, на другой – заделывали измельченной в почву после уборки урожая. Баланс углерода оценивали на основе учета прихода элемента в почву с растительными остатками (соломой и корнями) и его потерь в виде СО2 из органического вещества почвы за вегетационный период. Суммарные потери С–СО2  за период май – сентябрь рассчитывали на основании среднесуточной скорости продуцирования СО2 , которую определяли на поле чистого пара один раз в неделю абсорбционным методом. Минимизация, переход от вспашки к поверхностной обработке почвы, не оказала существенного влияния на среднегодовую урожайность пшеницы (2,49–2,60 т/га) и количество растительных остатков (1670–1818 кг С/га пашни). Между этими фонами обработки не обнаружено также значительных различий в среднегодовой минерализации органического вещества и балансе углерода в почве. Оба эти показателя существенно зависели только от количества поступавшего в почву растительного вещества (соломы и корней). Наиболее дефицитный баланс углерода в почве (-752 кг С/га пашни) зарегистрирован при отчуждении соломы с поля. При ее оставлении на поле баланс элемента становился значительно более благоприятным (-88 кг С/га пашни), приближаясь к бездефицитному состоянию. Сделан вывод, что при среднегодовой урожайности пшеницы в трехпольном зернопаровом севообороте около 2,5 т/га зерна и заделке в почву всей нетоварной части урожая в черноземе выщелоченном обеспечивался близкий к бездефицитному баланс углерода независимо от приема основной обработки

Experimental Substantiation of Feasibility of Using Enzymatic Fibrin Hydrolyzate-Based Medium to Obtain Components of Chemical Cholera Vaccine

The aim of the study was to experimentally substantiate the possibility of using a nutrient medium based on enzymatic fibrin hydrolyzate in order to obtain specific components of chemical cholera vaccine: cholerogen-anatoxin and O-antigen. Materials and methods. We used production strains of Vibrio cholerae 569B and V. cholerae M-41. Submerged low-volume cultivation was carried out in a laboratory fermenter for 8 hours, with automatic maintenance of cultivation parameters and feeding with glucose on the nutrient medium based on enzymatic fibrin hydrolyzate, containing (1.0±0.1) g/l of amine nitrogen, pH being (8.0±0.1). Cholerogen-anatoxin and O-antigens were obtained from detoxified formalin-treated centrifugates of culture liquids. The specific activity of V. cholerae antigens at the stages of cultivation and isolation was determined applying immunochemical methods. The preparation of the finished dosage form of the cholera vaccine and the coating of the tablets with an enteric coating was carried out in accordance with the regulatory documentation. Results and discussion. It has been shown that cultivation on the medium based on enzymatic fibrin hydrolyzate provides a stable growth of the biomass of V. cholerae production strains with a high level of specific activity of antigens. Comparative analysis of the main properties of the finished dosage form of laboratory batches with a commercial batch of chemical cholera vaccine has demonstrated compliance with the requirements of regulatory documentation. The results obtained has led us to conclusion that it is feasible to use the nutrient medium based on enzymatic fibrin hydrolyzate for cultivating production strains and obtaining specific components of the cholera vaccine

Use of bar processing to increase the shelf life of vitaminized sausages and their use for the correction of students' health

One of the priority directions of state policy in the field of healthy food is the development and integration of enriched foodstuffs with an increased expiration date into production. The purpose of researches is the study of effect of bar processing on the periods of storage of boiled sausages enriched with vitamin premix. The test samples of boiled sausages were processed under the pressure of 800 MPa within 3 minutes at a temperature of 0 ... +4 degrees C by means of a hydrostat after the end of the technological process. The control samples of boiled sausages were not processed under pressure. The safety of boiled sausages was estimated by organoleptic and microbiological indicators and pH, the content of vitamins in the product was researched in 8 and 16 days of storage. It has been established that in 16 days of storage the control samples of sausages did not conform to the requirements of regulating documentation; the shift of.. to the alkaline side, the increase in the quantity of mesophilic aerobic and facultative and anaerobic microorganisms has been noted. After 16 days of storage the content of PP and C vitamins in the control samples of sausages authentically decreased by 17.6% and 93.4% while the decrease in the test samples was 4.1% and 12.0%. The antioxidant activity of test samples of sausages is authentically 71.3% higher than that of the control samples (0.12 +/- 0.04 mol equiv/dm(3)). Against a background of use of vitaminized sausages an authentic increase in the antioxidant activity of catalase and ceruloplasmin is noted in the blood of students of the test group. Thus, it is established that the processing of boiled sausages enriched with vitamins, under high pressure has a bactericidal effect on microbic cells, prevents proteolysis, saves vitamins and, respectively, increases the expiration date of a foodstuff. The calculations for design of a high pressure hydrostat for foodstuff processing have been performed
