Main Trends in the Change in the Age and Sex Composition of the Volga Vyatka Region in 1939–1945

The article identifies the main trends in the change in the age and sex composition of the population of the Volga-Vyatka region in 1939–1945. In modern historical and demographic research, the transformation of the age and sex composition in 1939–1945 is insufficiently studied both for the USSR and its union republics and their territorial units, despite the fact that this period accounts for the most significant imbalance in the sex ratio in general and in individual age groups in the entire history of the Russian state. The paper aims to highlight the main trends in the change in the age and sex composition of the Volga-Vyatka region during the Second World War. The study was carried out based on an interdisciplinary approach using general scientific, specifically historical and statistical methods. It was concluded that the greatest distortion of the age and sex composition of the population of the Volga-Vyatka region falls on 1941–1945, which is a consequence of military and labour mobilizations: significantly among the younger generation of the villagers (aged 14 to 27 years), with the greatest variation among the generation born in 1919–1923.В статье определены основные тенденции изменения возрастно-полового состава населения Волго-Вятского региона в 1939–1945 гг. В современных историко-демографических исследованиях трансформация возрастно-полового состава населения в 1939–1945 гг. изучена недостаточно как по стране в целом, так и по союзным республикам и их территориальным единицам, несмотря на то, что на этот период приходится наиболее значительное за всю историю российского государства разбалансирование соотношения полов в целом и в отдельных возрастных группах. Цель статьи — выделить основные тенденции изменения возрастно-полового состава населения Волго-Вятского региона в годы Второй мировой войны. Исследование выполнено на основе междисциплинарного подхода с использованием общенаучных, специально исторических и статистических методов. В ходе анализа сделан вывод, что наибольшее искажение возрастно-полового состава населения Волго-Вятского региона приходится на 1941–1945 гг. и является следствием воинских и трудовых мобилизаций: существенно среди молодого поколения сельчан (от 14 до 27 лет), с наибольшей вариацией среди поколения 1919–1923 г.р

Effect of agrochemical AminoPlus brand: Amino ZN on growth and production processes, corn plant yields

Corn is one of the most widespread and popular grain crops in the world, which is due to its widespread use in the food industry, forage production and for technical purposes. In the world, the largest acreage of corn is concentrated in the USA and China; in the Russian Federation – in the Krasnodar Territory, in which more than 500 thousand hectares are sown with corn annually. The problem of increasing corn production can be solved, first of all, by increasing its yield. Given the high responsiveness of corn plants to organomineral fertilizers, an increase in yield and gross grain yields can be achieved by optimizing the nutrition regime. The tested agrochemical AminoPlus brand: Amino Zn is an organomineral fertilizer, which provides systemic and dosed foliar fertilization of corn plants (in phases 4-6 and 8-10 leaves), optimally providing the plant with nutrients, enhanced plant growth, the process of formation of reproductive organs and, ultimately, corn yield. The maximum yield of corn in grain – 53.5 centners per hectare (in the control – 44.4 centners per hectare) was obtained during foliar fertilizing of corn plants with the agrochemical AminoPlus brand: Amino Zn at a dose of 2.0 l/ha; the consumption of the spray material – 300 l/ha

Features of modern therapy of lupus nephritis

Kidney damage is one of the most serious problems of systemic lupus erythematosus (SLE). More than two thirds of SLE patients identified certain clinical and laboratory signs of lupus nephropathy from an isolated proteinuria to rapidly progressive lupus glomerulonephritis. Despite significant advances in the treatment of patients with SLE, lupus nephritis (LN) therapy remains one of the most difficult tasks. This article discusses the pros and cons of modern therapy LN and shows the data of our research.Поражение почек является одной из наиболее серьезных проблем системной красной волчанки (СКВ). Более чем у 2/3 больных СКВ выявляются те или иные клинические и лабораторные признаки волчаночной нефропатии от изолированной протеинурии до быстропрогрессирующего волчаночного гломерулонефрита. Несмотря на значительные успехи в лечении больных СКВ, терапия волчаночного нефрита (ВН) остается одной из труднейших задач. В данной статье рассмотрены плюсы и минусы современной терапии ВН и приведены данные наших исследований

Diffuse versus square-well confining potentials in modelling AA@C60_{60} atoms

Attention: this version-$2$ of the manuscript differs from its previously uploaded version-$1$ (arXiv:1112.6158v1) and subsequently published in 2012 J. Phys. B \textbf{45} 105102 only by a removed typo in Eq.(2) of version-$1$; there was the erroneous factor "2" in both terms in the right-hand-side of the Eq.(2) of version-$1$. Now that the typo is removed, Eq.(2) is correct. A perceived advantage for the replacement of a discontinuous square-well pseudo-potential, which is often used by various researchers as an approximation to the actual C$_{60}$ cage potential in calculations of endohedral atoms $A$@C$_{60}$, by a more realistic diffuse potential is explored. The photoionization of endohedral H@C$_{60}$ and Xe@C$_{60}$ is chosen as the case study. The diffuse potential is modelled by a combination of two Woods-Saxon potentials. It is demonstrated that photoionization spectra of $A$@C$_{60}$ atoms are largely insensitive to the degree $\eta$ of diffuseness of the potential borders, in a reasonably broad range of $\eta$'s. Alternatively, these spectra are found to be insensitive to discontinuity of the square-well potential either. Both potentials result in practically identical calculated spectra. New numerical values for the set of square-well parameters, which lead to a better agreement between experimental and theoretical data for $A$@C$_{60}$ spectra, are recommended for future studies.Comment: 11 pages, 4 figure

YV-plasty in the treatment of patients with recurrent bladder neck stenosis

Introduction. Bladder neck stenosis (BNS) is a late complication of surgical treatment for benign prostatic hyperplasia. Available methods of endoscopic correction in primary BNS have limited effectiveness, while in recurrent cases their use does not lead to satisfactory results at all. YV-plasty of the bladder neck (BN) is one of the available methods of treatment for recurrent BNS.Purpose of the study. To evaluate the treatment results of patients with recurrent BNS using endovideoscopic YV-plasty of the BN.Materials and methods. We retrospectively analyzed the treatment results of 8 patients with recurrent BNS who underwent endovideoscopic YV-plasty of the BN in the Urology Division No.1 of the St. Luke St. Petersburg Clinical Hospital from 2019 to 2021.Results. Endovideoscopic YV-plasty of the bladder neck was successfully performed in all 8 patients. The mean preoperative Qmax was 3.7 ml/s (1.8 – 5.7). At 6 months after surgery, the mean Qmax was 21.4 mL/s (16.7 – 24.1). The mean preoperative I-PSS score was 20.5 (17 – 24). The mean I-PSS score 6 months after surgery was 7.1 (5.0 – 9.0). No cases of de-novo stress urinary incontinence were registered.Conclusions. Endovideoscopic YV-plasty of the BN may be an effective and safe method of treatment of patients with recurrent BNS. However, further studies are needed to obtain long-term results

NbS3_{3}: A unique quasi one-dimensional conductor with three charge density wave transitions

Through transport, compositional and structural studies, we review the features of the charge-density wave (CDW) conductor of NbS$_{3}$ (phase II). We highlight three central results: 1) In addition to the previously reported CDW transitions at $T_{P1}$ = 360\,K and $T_{P2}$ = 150\,K, another CDW transition occurs at a much higher temperature $T_{P0}$ = 620-650\,K; evidence for the non-linear conductivity of this CDW is presented. 2) We show that CDW associated with the $T_{P2}$ - transition arises from S vacancies acting as donors. Such a CDW transition has not been observed before. 3) We show exceptional coherence of the $T_{P1}$-CDW at room-temperature. Additionally, we report on the effects of uniaxial strain on the CDW transition temperatures and transport.Comment: 16 pages, 18 figure

Influence immunosuppressive therapy with prednisolone and cyclophosphamide on the distant weather in kidney lupus nephrotic syndrome

In order to evaluate the effectiveness of treatment with different doses of prednisolone and cyclophosphamide and the duration of immunosuppressive therapy (1ST) on renal survival in patients with lupus nephritis (LN) with nephrotic syndrome (NS) were retrospectively studied 35 patients (3 men and 32 women). For verification SLE determined LE-cell antibodies to single-stranded DNA and anti-nuclear antibody. In 12 patients with LN was verified morphologically. With the development of NS all patients received corticosteroids (prednisolone) per os. In addition, 26 patients entered in addition to corticosteroids and cyclophosphamide. The study revealed that the preserved renal function at the onset of NS and rapid remission denied a positive impact on remote renal prognosis. Active therapy with prednisolone in the first 3 months of maintenance therapy contribute to long-term preservation of glomerular filtration rate, and cyclophosphamide has a positive effect on the course of LN with NS allows to preserve renal function for 20 years.С целью оценки эффективности лечения различными дозами преднизолона и циклофосфамида и продолжительности иммуносупрессивной терапии (ИСТ) на почечную выживаемость у больных волчаночным нефритом (ВН) с нефротическим синдромом (НС) было ретроспективного исследовано 35 пациентов (3 мужчин и 32 женщины). Для верификации СКВ определялись LE-клетки, антитела к односпиральной ДНК и антинуклеарные а/т. У 12 пациентов с ВН был верифицирован морфологически. При развитии НС все пациенты получали ГКС (преднизолон) per os. Кроме того, у 26 пациентов дополнительно к ГКС входил также циклофосфамид. В результате исследования было выявлено, что сохраненная функция почек в дебюте НС и быстрое достижение ремиссии отказывают положительное влияние на отдаленный почечный прогноз. Активная терапия преднизолоном в первые 3 месяца поддерживающей терапии способствуют длительному сохранению СКФ, и циклофосфамид оказывает положительное влияние на течение ВН с НС позволяет в течение 20 лет сохранять функцию почек

Factors affecting the development remission in lupus nephritis with nephrotic syndrome

In order to identify the factors affecting the timing of remission of nephrotic syndrome (NS) with lupus nephritis (LN), 35 patients (31 women and 4 men) were studied retrospectively. All of them underwent clinical examination and all patients received immunosuppressive therapy (1ST). As a result of this study, it was found that the 1ST, influencing the activity of LN is not allowed to reveal the impact of individual factors on the timing of immune inflammation remission NS, but the timing depends on the remission of initial doses of corticosteroids and at a dose of 0.8 mg I kg I day was significantly lower than at lower doses of corticosteroids.С целью выявления факторов влияющих на сроки достижения ремиссии нефротического синдрома (НС) при волчаночном нефрите (ВН), было ретроспективного исследовано 35 пациентов (31 женщина и 4 мужчин) ВН с НС. Всем проводилось общеклиническое обследование и все пациенты получали иммуносупрессивную терапию (ИСТ). В результате проведённого исследования было обнаружено, что ИСТ, воздействуя на активность ВН, не позволила выявить влияние отдельных факторов иммунного воспаления на сроки достижения ремиссии НС, но сроки достижения ремиссии зависят от инициальной дозы глюкокортикоидов (ГКС) и при дозе более 0,8 мг/кг/сутки достоверно ниже, чем при меньших дозах ГКС

Продуктивность и питательность зеленой массы сортов и гибридов ярового рапса в условиях Северо-Запада РФ

Scientific research was carried out on the experimental field of the North-Western Scientific Research Institute of Dairy and Grassland Farming, a separate subdivision of the VolRC RAS (Vologda Research Center of the Russian Academy of Sciences), located in the village of Dityatyevo, Vologda region. The soil under the field experiment is soddy-podzolic, medium loamy, and medium cultivated. Spring rapeseed is a valuable oilseed, fodder and industrial crop. It can be successfully grown in most regions of the Russian Federation, including the Vologda region. In the field experiment, we studied the cultivation of two varieties of domestic breeding - Yubileiny and Nabat and three hybrids of spring rapeseed of foreign breeding - Smilla, Salsa KL and Mirakl. The authors studied the productivity and nutritional value of spring rape varieties in the conditions of the North-West of the Russian Federation for 2020 and 2021. In the current unfavourable weather conditions in 2020, the development phases were delayed due to insufficient heat supply and insufficient moisture in 2021, which negatively affected the spring rapeseed crops. Harvesting for green mass was carried out in the recommended phases of plant development - the end of the newborn stage and the beginning of flowering. The high yield of the green group in 2020 was provided by the domestic varieties Yubileiny and Nabat (14.1 and 12,3 t/ha), and in 2021 - hybrids of foreign selection Salsa KL and Mirakl (10.9 and 10.2 t/ha). In terms of protein and fat content in the green mass, the best indicators for two years of research are in the varieties Salsa Kl and Miracle (in 2020, protein - 14.1%, fat - 3.1-3.3%; in 2021, protein 14.4- 15.9%, fat - 2.6-2.9%).Научные исследования выполнены на опытном поле Северо-Западного научно-исследовательского института молочного и лугопастбищного хозяйства – обособленного подразделения ФГБУН ВолНЦ РАН, расположенном в д. Дитятьево Вологодского района. Почва под полевым опытом – дерновоподзолистая среднесуглинистая среднеокультуренная. Яровой рапс является ценной масличной, кормовой и технической культурой. Его успешно можно выращивать в большинстве регионов Российской Федерации, в том числе и в Вологодской области. В полевом опыте изучали выращивание двух сортов отечественной селекции – Юбилейный и Набат и трёх гибридов ярового рапса зарубежной селекции – Смилла, Сальса КЛ и Миракль. Изучалась продуктивность и питательность сортов ярового рапса в условиях Севера-Запада РФ за 2020 и 2021 гг. В сложившихся неблагоприятных погодных условиях: в 2020 г. из-за недостаточного обеспечения теплом, а в 2021 г. вследствие недостаточного увлажнения – задерживалось прохождение фаз развития, что негативно сказалось на урожайности ярового рапса. Уборку на зелёную массу проводили в рекомендованные фазы развития растений – конца фазы бутонизации и начала цветения. Высокую урожайность зеленой массы в 2020 г. обеспечили отечественные сорта Юбилейный и Набат (14,1 и 12,3 т/га), в 2021 г. – гибриды иностранной селекции Сальса КЛ и Миракль (10,9 и 10,2 т/га). По содержанию протеина и жира в зеленой массе наилучшие показатели за 2 года исследований получены у сортов Сальса КЛ и Миракль (в 2020 г. протеина – 14,1%, жира – 3,1–3,3%; в 2021 г. – 14,4–15,9,и 2,6–2,9% соответственно)
