Published: November 2021

Исследование проводилось в 20142017 годах на опытном поле ФГБОУ ВО Казанский государственный аграрный университет. В сельском хозяйстве Российской Федерации в последние годы происходят позитивные изменения, связанные с переходом на ресурсосберегающие технологии возделывания культур. В кормопроизводстве в их основе лежит оптимизация системы удобрений, а также расширение посевных площадей и ассортимента многолетних трав. Например, результаты наших исследований показывают перспективность интродукции в сельскохозяйственное производство райграса многоукосного и его смесей с другими злаковыми многолетними травами. Наиболее выгодным приёмом ресурсосбережения в технологии возделывания многолетних трав с участием райграса многоукосного является ежегодное применение некорневых подкормок в виде современных комплексных питательных растворов, таких как Изагри NPK и Биокомпозит Коррект в объёме 6 л/га. Данные препараты стимулируют рост и развитие под и надземной массы растений, обеспечивая дополнительное получение от 0,65 до 1,17 т/га корм. ед., что превосходит вариант без удобрений на 3134. Важно отметить, что некорневая подкормка многолетних трав концентрированными питательными растворами позволяет заменить до 44 дорогостоящих гранулированных минеральных удобрений.
The field experiment took place in 20142017 at the Kazan State Agrarian University. Agriculture of the Russian Federation experiences positive changes in the sphere of resourcesaving cultivation technologies. Forage production undergoes optimization of fertilization systems, increase in farmlands and variability of perennial grasses. This paper points out the potential of Italian ryegrass and its mixtures with other perennial gramineous in agriculture. Annual application of modern foliar preparations such as Izagri NPK and Biokompozit Korrekt (6 l ha1) was shown to be the most effective practice. These preparations stimulated growth and development of roots and tops, providing additional yield of 0.651.17 t ha1 of feed units and exceeding the nonfertilized control by 3134. Topdressing of perennial grasses with concentrated nutrient solutions could substitute up to 44 of expensive granular mineral fertilizers.

Исследования проводись на Полевой опытной станции РГАУМСХА им. К. А. Тимирязева в 20162017 годах. В работе представлены результаты полевых опытов по внесению аммиачной селитры в различных сочетаниях с целью изучения эффективности применения азотной подкормки на озимой тритикале сорта Тимирязевская 150. В ходе проведения опытов определена количественная зависимость между урожаем зерна и внесением азота в возрастающих дозах в виде: Y 13,89 ln x 46,54. По величине максимальной урожайности (8,5 т/га) и показателям эффективности использования азота определена оптимальная доза удобрений (N120) для дерновоподзолистых среднесуглинистых почв. Применение азотной подкормки в виде разового внесения (N120), двукратного внесения (N6060) и трёхкратного внесения (N603030 N306030 и Nкр (70 20 10)) не выявило преимущества какоголибо варианта в сборе урожая. Очевидно экономическое преимущество разового внесения азота.

Published: November 2021

В странах ЕС любое негативное изменение продуктивности сельскохозяйственных животных (снижение привеса, удоя, репродуктивных показателей, а также повышение индекса заболеваемости) связывают с влиянием микотоксинов, поступающих, как правило, вместе с кормами. Поэтому основной задачей при диагностике микотоксикозов является выявление возможных продуцентов микотоксинов — «плесневых» грибов — в рационах животных. Имея полную картину выявленных в кормах грибов, можно предугадать виды токсинов, характер их воздействия на организм, возможный синергический эффект и порядок превентивного действия для снижения экономического ущерба от микотоксикозов. В статье отражены наиболее важные характеристики микроскопических грибов и их метаболитов; основные лимитирующие условия природно-климатического характера для токсинообразования в растительных кормах; описаны экстремальные условия введения животноводства в Якутии; приведено краткое описание результатов первых микологических исследований, проведённых в ходе научной экспедиции 1925–1926 годов, и первого случая микотоксикоза лошадей, выявленного научным сотрудником Якутского НИИСХ П. И. Николаевым (1983). Кроме того, проведён анализ официальных данных микологического изучения кормов растительного происхождения; установлена связь скармливания поражённых плеснеобразующими грибами кормов с болезнями микотического характера сельскохозяйственных животных. Для снижения количества плесневых грибов при заготовке сена, снижения чувствительности животных к негативному воздействию недоброкачественных кормов наиболее эффективно использование аэробных спорообразующих микроорганизмов Bacillus subtilis, а также природных сорбентов из местных ресурсов. Вопросы нейтрализации и снижения токсигенного эффекта кормов, контаминированных плесневыми грибами и их микотоксинами, остаются актуальными и требуют дальнейших научных исследований.
European Union correlates low livestock productivity with mycotoxin poisoning through consumed feed (decreased body weight gain, milk yield, reproductivity and increased susceptibility to various diseases). When analyzing mycotoxicoses it is highly important to identify putative toxin-producing strains of fungi in forage. Accurate identification of fungus species provides valuable information on toxin types, their influence on an organism, possible synergistic effects allowing effective application of preventive measures. This paper provides information on the most important characteristics of fungi and their metabolites. Environmental impact on toxin biosynthesis in plants is presented. Special aspects of Animal Husbandry in Yakutia are described. First mycological investigations of 1925–1926 are reviewed. Forage contaminations with fungi are analyzed. The correlation between fungus-infested forage consumption and disease outbreaks was determined. Treatment of fodder with spore-forming bacteria Bacillus subtilis or use of natural sorbents are able to prevent fungus spread in plant material as well as improve livestock health. Toxin poisoning still remains a serious problem in Agriculture.

Исследования по изучению влияния нетрадиционных кормовых добавок на химический состав мяса бычков симментальской породы были проведены на базе крестьянского хозяйства «Лонкур» в Сунтарском районе Республики Саха (Якутия). В статье представлена оценка эффективности кормовых добавок, приготовленных из местного природного сырья (50 и 100 г хвойной муки, 0,7 г/кг живой массы цеолита хонгурина и 35 г кемпендяйской соли). При анализе данных установлено, что опытные группы, получавшие кормовые добавки, имели лучшие показатели по убойному выходу и качеству мяса. Изучение химического состава мяса было проведено в соответствии с общепринятыми методиками. Было показано, что образцы мяса опытных групп превосходили контрольную группу по содержанию белка на 0,64 и 0,24%, жира — на 2,60 (P>0,999) и 1,73% (P>0,99), кальция — на 13,47 и 8,39%, фосфора — на 20,00 и 10,00%, железа — на 5,98 и 3,04%, меди — на 13,33 и 6,67%, магния — на 9,84 и 5,71%, селена — на 12,50 и 10,63%, витамина А — на 10,00 и 5,00%, витамина С — на 50,00 и 25,00%, витамина Е — на 33,33 и 11,11%, витамина В1 — на 6,25 и 3,13%, витамина В2 — на 30,77 и 15,38%, витамина В3 — на 11,43 и 7,14% соответственно. По накоплению цинка, свинца и кадмия в мясе опытных групп наблюдалась противоположная тенденция, связанная с сорбционными свойствами природных цеолитов. Полученные результаты показали перспективность использования нетрадиционных кормовых добавок в кормлении молодняка скота при производстве мяса в условиях Якутии.
The investigation took place at the Krestyanskoe Khozyaystvo “Lonkur” (farm) in the Suntarskiy rayon (district) of the Republic of Sakha (Yakutia). The effect of non-conventional feed additives was analyzed on meat chemical composition of Simmental bull calves. The article reports on the effectiveness of feed additives made from the local natural raw materials (50 and 100 g of conifer flour, 0.7 g per 1 kg of body weight of Hongurin’s zeolite and 35 g Kempendyai salt). The groups consumed feed additives showed the best characteristics of slaughter weight and meat quality. Meat chemical composition was tested according to the Standard techniques. The beef obtained from two experimental groups exceeded the control in protein by 0.64 and 0.24%, fat — by 2.60 (P>0.999) and 1.73% (P>0.99), Ca — by 13.47 and 8.39%, P — by 20.00 and 10.00%, Fe — by 5.98 and 3.04%, Cu — by 13.33% and 6.67%, Mg — by 9.84 and 5.71%, Se — by 12.50 and 10.63%, vitamin A — by 10.00 and 5.00%, vitamin C — by 50.00 and 25.00%, vitamin E — by 33.33 and 11.11%, vitamin B1 — by 6.25 and 3.13%, vitamin B2 — by 30.77 and 15.38%, vitamin B3 — by 11.43 and 7.14%, respectively. Since natural zeolites exhibit good adsorption properties the beef accumulated less Zn, Pb and Cd. The results proved high efficacy of the non-conventional feed additives used in this study.
A Modern-Day Diary: Notes for Future Humans
Authors: Itkonen Matti 
Published: November 2021

Abstract
Time and being can be seen as a space. A modern-day diary is a way of exploring that space or state of being. Outlining and shaping it requires word, image and imagination. The question is framed cultural-philosophically, and the mode of writing is poetic essayism. Otherwise, the creative untangling and differentiation of the poetics of lived space is not possible. After all, the goal is to combine science and art and weave them into the same reflective fabric. The essential aspects include thoughts about the fullness and filling of something, about its fulfilment. Then the present moment is not seen as marking a boundary in just one direction: it is not just an endpoint of the past. Nor is it exclusively the starting point of the future. The present must be seen as a boundary in two directions. The researcher’s gaze can simultaneously focus on both the bygone and the future. Consciousness meanders backwards down memory lane and journeys forwards on a trip of anticipation. A moment of insight means the fulfilment of time. Time is right for a deepening of self-understanding. Simultaneously, it also means fulfilling the ideal of self-reflection: an overall picture, clear and enlightened, of the the self’s place in time and being. When humans long for the past or dream of the future, they are living in the impasse of a now-moment. It is not a boundary in any direction. It is, in fact, a dimensionless photographic moment. Its spatial self-containedness results in no more than semi-fulfilment. The present becomes irrelevant. In fulfilment, humans themselves are the boundary facing in all directions. The overall perception of the enlightened subject reveals a reality that includes freedom, space, and human existence. Then it is easy for each and every person to exist as their own self.
A Demographic Study of the Multidimensional Poverty of Women in India
Authors: Ramya Rachel S. 
Published: November 2021

Abstract
Foremost in the Sustainable Development Goals (SGDs) of the 2030 Agenda, is the goal of achieving “No Poverty”. With nearly a decade yet to go, it is imperative to know the true nature and extent of poverty so that steps can be taken to eradicate poverty in all its forms. Multidimensional Poverty is a problem that persists on a larger extent in a developing country such as India, particularly among its women. The study uses the Demographic Health Survey data – India’s National Family Health Survey (NFHS), a nationwide survey conducted with a representative sample of women aged 15 to 49 throughout the country, to shed light on the nature and extent of deprivations faced by them. The deprivations faced by the women are measured along the dimensions of education, health and standard of living as per the global Multidimensional Poverty Index (MPI) jointly developed by UNDP (United Nations Development Program) and Oxford Poverty and Human Development Initiative (OPHI). Findings reveal that one-fifth of women in India are multidimensionally poor. Further subgroup decomposition reveals that higher levels of deprivations are found in women living alone, with higher age, having more number of children, widowed or divorced, husbands having multiple wives, those having more than one union and married before the legal age of marriage. The Government needs to focus its attention on the most deprived groups of women. Based on the nature and the extent of deprivations that they face, appropriate measures must be taken to bring them out of their destitution.

Published: November 2021

Abstract
Numerous studies show that there is a positive correlation between education and the economic development of the country. Strong education systems have a positive impact not only on the success of individuals but also on the economy of the entire country. Graduates equipped with the skills required by the labor market can easily find a place in this market. Knowledge and skills relevant to market demand increase productivity have a positive impact on economic growth and development. Unfortunately, Covid Pandemic has severely damaged the education systems. Governments, scientists, and experts provide us with statistical information daily around the world about both the slowdown in economic growth as a whole and the problems of individual sectors of the economy. These are the problems and numbers that are already visible and it can be said that the losses are easily measurable. However, the damage caused to the economy by education systems affected by the pandemic will be felt by countries and humanity years later, nor will it be easy to calculate. The problem is even more difficult in poor and developing countries. This paper aims to study the impact of the Covid Pandemic on the education system and economy in Georgia. The research examines the reports and studies of various international organizations, analyzing the secondary data obtained from them. Local policy documents, government reports and regulations, and papers of different researchers have also been studied, conclusions have been made and relevant recommendations have been developed.
The Plasmid Differences in Multi-Drug Resistant Opportunistic Pathogenic Soil Strains of Pseudomonas and Stenotrophomonas
Authors: Babayan Bella 
Published: November 2021

Abstract
The antibiotic resistance and especially mult-idrug resistance is one of the most important factors for any microorganism survival in nature. In a majority of cases the resistance to antibiotics, as a property is being defined by several genes which are localized in plasmids, transposons and in other mobile genetical elements. As a result, it has been found out that in some native opportunistic pathogenic soil strains of Pseudomonas and Stenotrophomonas, the resistance to different antibiotics is caused by simultaneous presence of different plasmids in cells. Besides, the genes of resistance to various classes of antibiotics of I, II, III generations. They can be localized on one plasmid or in more than one plasmids of current bacterial cell. These plasmids of researched strains of Pseudomonas and Stenotrophomonas are able to stabile replication not only in cells permanently contacting with compatible antibiotic molecules in environment, but also in case of long-term cultivation of bacteria on synthetic media without any antibiotic. The antibiotic resistance of researched Pseudomonas and Stenotrophomonas strains, which is caused by mobile genetical elements, can be transferred among the microorganisms both in frames of one species and in interspecific and intergeneric gene transfer processes. The plasmids with the presence of genes of resistance to different antibiotics can be transferred to different microorganisms independently, with the forming of new resistant strains, which are differing in resistance to natural antimicrobial organic acidcs as well as their synthetic derivatives and it has a significant ecological and medical importance.

Published: November 2021

Abstract
This paper is focused on exploring the learning experiences of students of Faculty of Education Sciences, University of Elbasan, Albania, during the period of sudden movement from teaching in auditorium to the online learning environment due to the COVID-19 pandemic.

The purpose of the study was to identify the positive and negative aspects of online learning as experienced by students, as well as to find out their preference for the most appropriate form of higher education delivery (face-to-face, hybrid, online) for young people of digital age.

The methodology used in this study included an item-based questionnaire to collect data which was developed through a web-based application known as Google Forms and was delivered to students via Internet. Qualitative and quantitative analysis was undertaken for the answers obtained by the open-ended and closed-ended questions.

The results of the study showed that the biggest challenge for all students was the immediate adaptation to the form of distance learning. Most of them had perceived the online learning dominated more by negative experiences than positive ones.
The study concluded that new reality created by COVID-19 tested the current capacity of Higher Education Institutions regarding the ICT integration process in teaching. As this process was progressing very slowly, universities were found unprepared to transfer the teaching process from the auditorium to the online environment with the same quality. In order to meet the demands of the future, it is imperative that every university to plan strategically the increase investment towards its digital transformation.

Abstract
The most medically representative plant in the Apocynaceae family is Vinca minor. Vinca minor is a perennial, herbaceous plant, commonly known as Saschiu. In the present research we aimed to isolate the indole compounds from Vinca minor L. and to carry out some physico-chemical studies on these compounds: UV-VIS spectroscopy and the determination of the polyphenols content using Folin-Ciocâlteu method. The spectrophotometric study of the alcoholic plant extracts obtained from the leaf and stem of Vinca minor was performed using the UV-VIS spectrophotometric method and a VWR UV-630PC double beam spectrophotometer. Both samples of plant alcoholic extracts obtained from the leaf and from the stem of Vinca minor L. had the specific absorption maxima detected in the range 225-350 nm and the absorbance maximum in both cases was 3.5 (u.a- absorbency units). The total content of polyphenols was determined by the Folin-Ciocâlteu method from alcoholic extracts of different concentrations: 40%, 70%, 96% (T40, T70, T96, F40, F70, F96) obtained from the leaf and stem of Vinca minor plant using the spectrophotometer model JASCO- 550 UV VIS. Regarding the alcoholic extracts obtained from the leaf of Vinca minor L., the concentrations of polyphenols were between 812.50 mg / 100g pv and 1737.50 mg / 100g pv and and in the case of alcoholic extracts obtained from the strain, the results were between 1525.00-3962.50 mg GAE / 100 g pv, results that were in accordance with the literature.
