The Importance of Ecological Redundancy for Ecosystems Restoration
Authors: Londe Vinícius
Published: May 2021

Restoration ecology is a multidisciplinary science that exchanges several concepts with other scientific fields to improve its practices. In this article, I discuss the ecological redundancy concept and its implications and applications on ecological restoration. Ecological redundancy was coined in the early 1990s to characterize those species that play similar (equivalent) functions in the ecosystem. The concept made it possible to segregate species into functional groups that operate in maintaining the system. I searched the literature and found that although some restoration models naturally consider this concept, studies in areas undergoing restoration which directly measure and test the ecological redundancy are still rare (n = 14). I provide evidence that distinguishing redundant species and identifying key species is feasible for ecological restoration. Additionally, I suggest that redundancy should also be part of the restoration monitoring, for example, by checking if functional groups have been recovered. Theory predicts that if ecological redundancy is correctly incorporated in restoration, projects with more chances of success will be created because redundancy tends to increase ecosystem resilience. Resilience is a crucial factor for restoration sustainability in a changing environment.

Neonatal Late-Onset Sepsis (LOS) is a leading cause of mortality in the Neonatal Intensive Care Unit (NICU). The microbial characteristics of LOS are of primary importance in guiding clinical antisepsis practice, and strategies to prevent and treat neonatal LOS, in turn, influence the pattern of LOS pathogens. This study is a retrospective descriptive study with a cross-sectional approach conducted between 2016 until 2020 in the neonatal ward (level II-III) of the Sanglah General Hospital, Bali. Data collected consists of demography, clinical characteristics, laboratory results, and outcomes. Subjects in this study dominated by male (64%), gestational age > 37 weeks (56%), born ≥ 2.500 grams (54%), last mother education mostly in Senior High School (56%), spontaneous delivery method (54%) and 31 (62%) subjects were referral from other hospital and primary health care. Most of the subjects were lethargic (68%) and 15 (30%) subjects were died. Laboratory finding normal leukocyte, neutrophil, lymphocyte, hemoglobin, thrombocyte and IT ratio but have higher procalcitonin result. Poor outcome group were dominated by male, smaller gestational age, VLBW, and neonates who experience lethargy, temperature instability, respiratory distress and got positive blood culture.

Candida spp., are saprophytic yeasts capable of creating a favorable environment for bacterial infection, amplifying or inhibiting their activity. On the other hand, bacteria produce molecules that reduce the proliferation of Candida spp or promote their adherence to surfaces. The resurgence of typhoid and paratyphoid fevers in endemic individuals and the relative effectiveness of contemporary conventional therapies arouse curiosity to explore other factors that may influence, the re-emergence of infection in patients. We carried out a cross-sectional study of 2500 patients in four hospitals in the city of Douala, Cameroon, from January to December 2019, to determine the influence of Candida spp., on the onset of these infections in patients. Widal and Felix test was used to form the sample, culture on specific media and microscopy confirmed the identity of Salmonella typhi, Salmonella paratyphi and Candida spp. Biochemical tests on a classic tube gallery revealed the biochemical characteristics of bacteria. The results showed that infection with S. typhi is predominant, 32.76 % versus 18.4 % of S. paratyphi infection. Infection with Candida spp., would increase 4-5 times the frequency of infection with S. typhi and S. paratyphi, respectively from 3.08 % to 26.03 %, and from 7.08 % to 32.76 %. The presence of Candida spp increases the risk of reoccurrence of S. typhi and S. paratyphi in patients.
Community knowledge towards electric vehicles and policy part II: A pilot study of Edmonton Height underserved neighborhood in Huntsville, Alabama
Authors: Jacob Oluwoye
Published: May 2021

Introduction: Electric Vehicles (EV) are fast emerging globally as a viable alternative to traditional fossil fuel burning cars and are now being presented as a resolution for the problem of dependence of fossil fuels, increasing emissions, and other environmental issues. Purpose and Objective: The study explores the neighborhood knowledge toward green mobility and the objective of this paper is to investigate and examine neighborhood perceptions and understand their knowledge towards the electric vehicle. The research paper goal necessitated the knowledge of the underserved community towards green mobility. Methods: Following the literature review research phase, the researcher conducted several semi structured interviews with underserved community. To best augment the quantitative, data were gathered from underserved Edmonton Height community, through the design of questionnaire survey. Data collection took place during the last two weeks of October 2018. Neighborhood households were approached during the day and evening in their residents using a structured questionnaire. Results: The analysis reveals that that 60% of the respondents not aware of plug-in EV incentives (such as tax credit, rebate, high occupancy lane access, reduced tolls, lower vehicle registration rates, or discounted electricity rates) offered by the federal government; their state government; local community; their electricity provider; their employer, while 10% indicated federal government and 10% local community and 5% indicated electric providers, 5% employers and 5% state government. However, the pilot results are a useful estimate of the number of households residents residing in Edmonton Heights don’t know that plug-in EVs can be recharged from a regular home outlet. Conclusion: The paper concludes that the progress that the electric vehicle industry has seen in recent years is not only extremely welcomed, but highly necessary considering the increasing global greenhouse gas levels and it should be noted that a range of technology options is being aggressively explored to facilitate the transition to a more sustainable transport system. Near term, technologies such as EVs can provide sustainable mobility and help alleviate some of the problems created by conventional vehicle powered by fossil fuels. Notwithstanding, the pilot results are a useful estimate of the number of households residents residing in Edmonton Heights don’t know that plug-in EVs can be recharged from a regular home outlet.
How do medical doctors respond to the inappropriate patient request?

Published: May 2021

Medical doctors need the skill to acquire how they are responding to inappropriate patient's requests. The FAVER approach starts with recognizing inner uncomfortable feelings, which signals that the patient's request is inappropriate. Assuming that the patient doesn't know that their demands are "immoral." The medical doctors need to say "NO" in an explicit state and give excuses such as inadequate medical care, illegal, dishonest, or against policy and avoid lengthy explanations.

Preconception care is the provision of biomedical, behavioral and social health interventions to women and couples before conception occurs. This study aimed to assess women’s knowledge, practice, perceived views and ideas and associated factors in preconception care amongst women attending antenatal care at Nnamdi Azikiwe University Teaching Hospital, Nnewi, Anambra state, Nigeria. A facility based cross-sectional study conducted among 150 randomly selected reproductive age group women who attended antenatal clinic from September 9 to September 26, 2020.The data were collected using self-administered and interviewer-administered questionnaires. The data were analyzed using Statistical Package for Social Sciences version 20.0. The study revealed 31.3% overall knowledge of preconception care. The knowledge level on preconception care was significantly associated with occupation, level of education, residence, number of pregnancies and past obstetrics complications. Age has no association with the level of knowledge. Only about one-fifth of the participants have good knowledge of the importance of folic acid use prior to and during pregnancy (17.3%), 32% had wrong knowledge and the rest had no knowledge (50.7%). Majority of the participants (87.7%) had prospective views concerning preconception care encouraging every woman to partake in it. In this finding, the level of women’s knowledge on preconception care was very low. Having a high level of education, living in urban area and having an obstetrics history were associated with good knowledge. The finding also showed positive views on the uptake and practice preconception care. This finding suggests that there is a need to give more emphasis on educating women on preconception care with the sole aim of achieving a sound maternal and child health.

Published: May 2021

This review paper looked at some of the most relevant material on senior citizens' issues. The study aimed to use secondary data analysis to determine the most pressing needs of senior citizens. The essay examined their current situation, problems, and needs. Nepal's elderly population is growing every year. They have not received adequate care from the government. The private sector made a considerable contribution to this endeavor. Both the government and the private sector have made efforts in this regard. They are currently battling to meet their basic requirements. Senior citizens not receiving adequate food and has disability mental illnesses are two of the several misfortunes listed in the research papers, both of which are public health concerns. They are in dire need of proper nutrition as well as mental health promotion. That is an area where both the government and the private sector can focus. COVID-19 has the highest Case Fatality Rate among elderly adults, and Nepalese senior citizens have a high mortality rate. The high mortality and fatality rates of COVID among the elderly have prompted policymakers to focus on senior citizens' health and living conditions. There are three tiers of government in Nepal. If they understand the issue, they will develop strategies and services to aid senior citizens. In this changing environment, the public and private sectors at various levels must enhance cooperation to improve the dreadful situation of senior citizens. Also, the importance of family in senior citizen care has grown in recent years.

Published: May 2021

Diabetes mellitus type 2/ DM2/ - is increasing in incidence in United states and throughout the world mostly due to increasing Obesity epidemy- around 40 % of adult people in USA. Two are the major defects of the disease- insulin resistance which sets up the stage 4-7 years before DM type 2 is diagnosed and relative to the increased resistance insulin deficiency. After the diagnosis of DM type 2 the Insulin resistance stays usually constant while the Insulin deficiency progresses necessitating the intensification of the therapy and eventually the need of Insulin . Initially the insulin is started usually as a basal and eventually as the DM type 2- progresses we add bolus rapid acting insulin to major meal- basal plus regimen/BP/ and eventually to every meal- basal- bolus /BB/ insulin. This intensification of the therapy is frequently able to control DM type 2 , but leads to significant 3-4 kg weight gain with risk of hypoglycemia. Other option of intensification of the therapy of DM type 2 is to add to the oral anti - diabetic medications only basal Insulin and GLP1- RAs. GLP1-RAs decrease post prandial blood sugar as the rapid acting insulin does and the long acting GLP1-RAs also decrease fasting blood sugar. GLP1- RAs suppress the appetite and theoretically might lead to weight loss and less incidence of hypoglycemia compare to BP/BB Insulin regimens, because they act on glucose dependent manner- increase the endogenous insulin production only if the blood sugar is elevated . In our meta- analysis we concentrated our efforts into looking at the side effect of GLP 1- RAs and basal- Insulin combination compare to BP/BB insulin combination like weight loss/gain, incidence of hypoglycemia, adverse events- mainly the gastrointestinal ones. Our secondary end point was the change in HbA1c between GLP1-RAs and basal insulin group compare to BP/BB insulin group in patients with HbA1c 7-11%. This is the first meta- analysis as far as we now comparing those 2- combinations – BB/BP insulin to GLP1-RAs and basal insulin in the terms of looking as a primary end point at the side effects of those combinations.

Three patients were presented in order to make differential diagnosis between affective disorder and dementia. All patients have diagnosis of affective disorder and they were in stable remission under antidepressive therapy. When pathological stealing occurred, there was a diagnostic dilemma: is it a new manifestation of affective disorder, rare side effect of serotonergic antidepressants or symptom of dementia. Neuroimaging methods, as well as neuropsychological testing identified that in these patients other symptoms of prefrontal dementia also existed. Frontotemporal dementia (FTD) is frequently misdiagnosed with depression, and so far, inadequately treated with higher doses of antidepressants. Such therapy could worsen clinical feature. These patients were successfully treated with combination of memantine and low doses of serotonergic antidepressants. In the future, multicentric investigation should be conducted to confirm effective therapeutic combination of psychopharmacs in cases of pathological stealing in FTD.
BLOCH NA AMÉRICA LATINA AS RAÍZES ÉTICAS DA FILOSOFIA DA ESPERANÇA
Authors: Lorenzoni Anna Maria
Published: May 2021

No presente artigo, busca-se fazer uma breve reconstrução dos percursos históricos e teóricos que permitiram o acolhimento e a apropriação de conceitos fundamentais da filosofia blochiana no interior das inquietações sociais latino-americanas, bem como destacar as particularidades das interpretações difundidas no Brasil. Tendo como fio condutor a busca dos elementos éticos da filosofia blochiana, o percurso se inicia com uma contraposição entre as literaturas secundárias a respeito do autor disponíveis no Brasil e na Alemanha. A ambiguidade entre a manifesta importância dos pressupostos éticos da filosofia da esperança enfatizada pelos comentadores brasileiros contraposta ao papel secundário atribuídos pelos comentadores alemães é, então, explorada a partir de um rastreamento dos caminhos que trouxeram a filosofia blochiana até o continente latino-americano. A despeito do ateísmo do filósofo alemão, na América Latina, a filosofia da esperança aliou-se à “herética” teologia da libertação, sendo essa a sua porta de entrada principal. Aqui, a filosofia de Bloch se confunde e entrecruza com a própria história do marxismo e do cristianismo no continente, repercutindo na originalidade dos movimentos sociais e das bases éticas que os orientam. A utopia, tal qual concebida pelo autor, revela-se como ponto de encontro fundamental entre a fé e a política.
RELIGIÃO DO ÊXODO. SOBRE O ATEÍSMO NO CRISTIANISMO DE ERNST BLOCH
Authors: Dietschy Beat
Published: May 2021

Ernst Bloch tornou-se conhecido na Alemanha como um dos mentores do movimento de 1968. O que é menos conhecido é que ele forneceu impulsos para a teologia política e, em parte, para a teologia da libertação. Seu livro Ateísmo no cristianismo: sobre a religião do êxodo e do reino, surgiu no ano de 1968; porém, como o próprio título já indica, não trata do movimento de protesto da época. O artigo quer mostrar como, mesmo assim, o livro e o seu ateísmo não ortodoxo puderam contribuir para a expressão das motivações centrais da revolta de então contra estruturas autoritárias e por uma nova cultura da vida. O faz partindo do Espírito da utopia, primeiro trabalho de Bloch, o qual há exatamente meio século já procurava fazer da resistência à guerra e ao capitalismo uma questão filosófica central. Na sequência, é perseguido como a revolução no “céu” da linguagem simbólica religiosa se associa com a crítica marxiana à religião e como, no contexto da tradição sócio-revolucionária de uma leitura herética da Bíblia, é trazida para o aquém. Conclui-se que a junção desses elementos possibilita a Bloch uma transformação da religião e sua reinserção em práxis libertadoras em busca do autoencontro humano. Por fim, será interrogado sobre a relevância de uma tal herança da religião para sociedades crescentemente pós-tradicionais. É apropriado se contrapor às fantasias de poder megalômanas de uma religião de mercado sem limites, que se espalhou na esteira das revoltas de 1968?
ERNST BLOCH E A CONVERSÃO UTÓPICA
Authors: Ferraro Gianfranco
Published: May 2021

O artigo tenta investigar a abordagem à utopia de Ernst Bloch, focando-se em particular no Espírito da utopia. A partir da interpretação de Miguel Abensour da utopia como forma de “conversão”, e através das reflexões de Pierre Hadot sobre a história da conversão como fenómeno espiritual que interseta quer a filosofia quer a religião, o artigo estuda a modalidade com que uma conversão utópica se define em Bloch. A consequência desta reflexão consiste na possibilidade de abordar a própria filosofia de Bloch, tal como a tradição utópica no seu todo, dentro do horizonte da filosofia como maneira de viver, conforme a abordagem de Hadot: uma modalidade filosófica esta, característica da Antiguidade, mas também presente na modernidade, caracterizada por técnicas e práticas de escrita que visam, mais do que a uma compreensão teórica dos fenómenos, a uma transformação das práticas de vida. Recuperando esta modalidade filosófica, Bloch abre o caminho para uma espiritualidade política na qual se enraíza, por fim, a potência transformativa da própria utopia.
MARXISMO E RELIGIÃO OU O ATEÍSMO NO CRISTIANISMO: A ANÁLISE DE ERNST BLOCH
Authors: Maciel Marta Maria Aragão , Vieira Antonio Rufino
Published: May 2021

No deslindar da reflexão acerca da relação entre utopia e religião, Ernst Bloch pode ser apontado como um autor segundo o qual o ateísmo é a verdade da religião, tal como pode sugerir o título de seu importante trabalho O ateísmo no cristianismo (1968). De fato, a questão da religião é tão relevante como experiência utópica que várias das obras de Ernst Bloch abordam o tema, encontrando-se também presente em obras como O Espírito da utopia (1918), Thomas Münzer: teólogo da revolução (1921), e na sua mais importante e conhecida obra, O Princípio esperança (1954-1959). Pretendemos refletir o significado da relação entre marxismo e religião no pensamento de Ernst Bloch, relação essa que nos permitirá compreender como é apenas aparente o paradoxo existente ao nos reportarmos ao autor de Herança dessa época como um “marxista cristão”, ou como um pensador “ateu religioso”, ou mesmo “ateu cristão”. Para tanto, necessitamos refletir a relação estabelecida entre utopia e religião, central na obra do autor aqui em questão, cujos lineamentos busca-se vincular diretamente ao marxismo. Como parte da superestrutura, a religião ocupa, com efeito, lugar central na preocupação filosófica de Ernst Bloch, de modo a não podermos desconsiderar essa experiência utópica que ocupa espaço tão relevante em sua produção teórica.
MARXISMO E ESPERANÇA: ERNST BLOCH, PENSADOR REVOLUCIONÁRIO
Authors: Löwy Michael
Published: May 2021

Ernst Bloch, pensador marxista, dedicou toda a sua vida à ideia de utopia. Esta compõe o coração da reflexão de Bloch desde seus primeiros escritos, O espírito da utopia (de 1918) e Thomas Münzer: teólogo da revolução (de 1921). Referindo-se aos seus primeiros escritos, Bloch os definia como romântico-revolucionários. O romantismo revolucionário do pensador alemão alcança sua mais importante contribuição em O princípio esperança, o livro mais importante de Ernst Bloch e, sem dúvidas, uma das obras mais importantes do pensamento emancipatório do século XX. Tal livro enciclopédico representa uma imensa e fascinante viagem pelo passado, em busca das imagens do desejo e das paisagens da esperança. É válido ressaltar que por “romantismo” entendemos não somente uma escola literária do início do século XIX, mas uma vasta corrente cultural de protesto em nome de certos valores sociais e culturais do passado, contrária à civilização capitalista moderna. Nesse contexto, não se trata de uma nostalgia do passado, mas de resgatá-lo na crítica do presente, e rumo ao futuro possível. Não casualmente a tematização da utopia se vincula a uma ontologia da possibilidade que caminha na direção de um conceito dialético de realidade na direção do marxismo. Assim, pretendemos refletir, no presente texto, como esse resgate da utopia vai de encontro com uma ontologia do ainda-não-ser, na base da qual se afirma que o mundo, tal como existe, é falso. Em suma, pretendemos elucidar alguns dos conceitos centrais da filosofia da esperança e da utopia concreta de Ernst Bloch, no interior de uma contribuição no âmbito do marxismo.
BLOCH – PROCURA POR NÓS MESMOS NO UTÓPICO. O CAMINHO DO ESPÍRITO DA UTOPIA AO CONJUNTO DA OBRA
Authors: Schmied-Kowarzik Wolfdietrich
Published: May 2021

Espírito da utopia, de Ernst Bloch, foi escrito durante os anos da I Guerra Mundial, durante sua emigração na Suíça, e publicado em 1918. Neste livro, Bloch procura contrapor à loucura da guerra a pergunta pelo sentido, a qual, quando existencialmente entendida, há de conduzir a um “autoencontro” conosco mesmos. Bloch concentra-se especialmente em três círculos temáticos: o autoencontro nas artes plásticas, na música e na “questão inconstrutível” para nós mesmos, na filosofia. O movimento dialético interno disso Bloch resume, como lema de seu filosofar, em três frases: “Eu sou. Mas eu não me tenho. Com isso nós primeiramente seremos”. Já no “com isso nós primeiramente seremos”, fica claro que Bloch não compreende seu existencialismo de modo individualista, pois o autoencontro filosófico do ser humano somente pode ser exitoso em uma sociedade humano-social. Portanto, o compromisso com uma sociedade socialista e ecológica não deveria ser degenerado a algo técnico-científico, mas, justamente em relação ao socialismo a ser construído, aquela questão com a qual a filosofia já desde sempre se ocupa deve ser posta da forma ainda mais radical. Nosso engajamento por uma convivência mais humana entre nós e por uma interação responsável com a natureza deve ser capaz de resistir até mesmo diante de um possível fim da nossa história terrena. É nisso que culmina o dramático capítulo final “Karl Marx, a morte e o apocalipse” e nisso consiste o persistente desafio do Espírito da utopia para nós hoje.

Published: May 2021

PURPOSE. Consider the electrochemical technologies used for the production of hydrogen at gas stations and the operation of hybrid electric vehicle engines on storage batteries with fuel cells. Comparative analysis of the production and use of energy by electrochemical and traditional methods in vehicles. METHODS. Based on the analysis of literature data and mathematical calculations. RESULTS. For a light electric vehicle, the calculation of the amount of electricity that can be obtained in a fuel cell by processing 1 kg of hydrogen was carried out. It has been shown that a hydrogen electric car can travel about 100 km for 1 kg of hydrogen. A comparison was made of the fuel costs for different types of automotive engines for the current market conditions in Russia and the EU countries. CONCLUSION. Hydrogen can become the environmentally friendly fuel of the future, reduce global dependence on fossil fuel resources and reduce carbon dioxide emissions from the transportation industry. Today, green technologies have made significant progress, modern vehicles of various classes on hydrogen fuel have been developed and sold around the world, and their price characteristics are already comparable to existing traditional technologies. The advantages of electrochemical technologies for the production and use of hydrogen in the road transport sector are sufficient to make hydrogen a serious energy candidate for modern transportation systems.
Socio-economic problems of hydrogen energy development
Authors: Pletnev M. A. , Kopysov A. N.
Published: May 2021

THE PURPOSE. To consider the features of the socio-economic development of Russia in the context of the fourth energy transition, which is based on the use of renewable energy sources and hydrogen as an energy carrier. To carry out a comparative analysis of approaches to the development and implementation of hydrogen energy programs in developed countries and in Russia. METHODOLOGY. To solve this problem, the method of analyzing the regulatory framework, monographic, scientific and analytical literature, program documents of various levels, real steps of the authorities in the implementation of the fourth energy transition was used. DISCUSSIONS. The current economic model of energy production and consumption is based on an increase in entropy, which leads to irreversible changes in the global ecosystem. The fourth energy transition involves the delocalization of energy production and the use of dissipated energy, which leads to a decrease in entropy. The transition to the use of renewable energy sources carries economic risks associated with the loss of established markets for traditional energy sources, a reduction in the production of products and services for the oil and gas sector of the economy, as well as the introduction of a "carbon tax" on the export products of Russian companies. Russia has achieved certain results in the development of hydrogen energy technologies, which can lead to access to international markets for hydrogen and technologies for its production. It is necessary to work with the public to explain the benefits of green energy. It is important to coordinate the actions of the Government of the Russian Federation and business to reduce costs during the transition to new energy. CONCLUSION. The authors have proposed measures that must be taken into account when implementing the Action Plan ("road map") for the development of hydrogen energy in the Russian Federation until 2024. 1. To supplement the roadmap with a system of measures to inform the population of the need to introduce green energy, including programs of additional, general secondary and higher education. 2. To change the structure of the Federal State Educational Standard of general secondary education in terms of including chemistry and biology in the list of compulsory subjects in order to provide personnel with hydrogen energy. 3. Determine the priority of projects on renewable energy sources and hydrogen energy in the formation of tender documentation by the development institutes of the Russian Federation. 4. Ensure real decarbonization of the country's energy sector to maintain the export positions of raw materials, food and industrial goods of Russian manufacturers.

The temperature was estimated of live steam superheat depending on the temperature of the additional heating of the feed water. The results are presented of the calculation of the generated peak power by the power unit and the efficiency of conversion of the night off-peak power of the NPP into peak power, as well as the efficiency of the power unit of the NPP depending on the temperature of additional heating of the feed water. Main regularities are given for taking into account the fatigue wear of the main equipment of the hydrogen facility, including the rotor of the NPP turbine in the conditions of the stress-cyclic operation. The results are presented of assessing the cost of peak electricity NPP in combination with a hydrogen facility in comparison with a pumped storage power plant (PSPP) both for the current period and for the future until 2035. CONCLUSION. Hydrogen facility efficiency and competitiveness depends significantly on the intensity of the use of the main equipment in the conditions of the intense-cyclic operation. The hydrogen facility will competitiveness noticeably increase in comparison with the PSPP in the future. Efficiency of the NPP power unit and NPV is highest when the feed water is heated to 235 ° C and superheating of live steam in front of the high-pressure cylinder of the C-1000-60/1500 turbine up to 470°C.The hydrogen facility competes with the PSPP with her specific capital investment at the level of 660 USD / kW, provided that the boosting capabilities of the turbine are used with live steam overheating at 300 ° C and additional heating of feed water to 235°C on the current period. The PSPP does not compete with the hydrogen facility both for the current period and in the future with her specific capital investment of $ 1,500 / kW and above.

THE PURPOSE. The study is aimed at studying the effect of fuel gases of various component composition on the environmental performance of the GE 6FA gas turbine unit. Consider using hydrogen as primary sweat to minimize emissions and improve performance of the GE 6FA gas turbine. METHODS. To achieve this goal, the ASGRET (Automated system for gas-dynamic calculations of power turbomachines) software package was used. RESULTS. The article discusses promising directions for the utilization of CO2 using highly efficient technologies with further use or disposal. A mathematical model of a GE 6FA gas turbine unit, diagrams of changes in the main characteristics and the composition of emissions when operating on various types of fuel, including hydrogen, are presented. CONCLUSION. The studies carried out show that a change in the component composition of the gas affects the energy characteristics of the engine. The method for determining the quantitative composition of COx, NOx, SOx in the exhaust gases of a gas turbine plant is presented. The transition to the reserve fuel kerosene leads to an increase in the amount of emissions, which must be taken into account when designing systems for capturing harmful emissions with a dual-fuel fuel gas supply system. The use of hydrogen as a fuel for gas turbines allows to reduce not only the cost of fuel preparation, but also to minimize emissions and improve the performance of the gas turbine plant.

The work is devoted to the study of students' attitude to the use of information technology in the educational process. The results of the survey of students on the perception of teachers and students of the process of information learning and the assimilation of materials for the courses they have mastered are analyzed.

Research is aimed at increasing the scientific mobility of students and teachers in the field of technical education by means of the introduction of distance learning methods and the ability to update the content of education. The main attention is paid to methods of updating information support of students for each type of classes, methods of combining general knowledge in specialties, which help to strengthen interdisciplinary links, methods of tracking course terminology and methods of combining theoretical and practical parts of the discipline.

The analysis of the use of remote technology in the conditions of COVID-19 is carried out. The world experience and the experience of Ukrainian universities are analyzed. The positive and negative aspects of distance learning are characterized from points of view of teachers and students.

The purposes and tasks facing students in the system of technical and physical and mathematical education in the conditions of distance learning are defined. The factors influencing quality of training experts in technical and physical and mathematical specialties in the conditions of distance learning technologies are discussed.

It is determined that the full or partial use of modern distance technologies will allow to achieve a qualitatively new level of higher education, which largely depends on understanding and using the modern information and communication technology. Methods of quality management of continuous technical and physical and mathematical education are defined. These methods will allow to train competitive professionals who will not only meet the current level of development of science and technology, but also ahead of it.

Accurate control of the production process of field crops, performed in the system of precision agriculture, means a spatially differentiated implementation of agrotechnical measures based on spectral measurements. The study of the optical properties of spring wheat crops under changing conditions of agricultural technology was carried out in a multifactorial microfield experiment at the Menkovsky branch of the Agrophysical Research Institute (Leningrad Region, Gatchinsky District). The experimental scheme included the study of the effect of sowing rates (5 and 6 million seeds per ha), doses of nitrogen fertilizers (0, 60 and 120 kg a.s. per ha) and weed infestation of experimental plots (natural background, application of herbicide). According to the research results, it was revealed that the optical properties of spring wheat crops are largely determined by the degree and type of weed infestation (8,5-48,1%), to a lesser extent – by the introduction of nitrogen fertilizers (2,7-21,6%). The influence of the sowing rate on the spectral characteristics of crop is insignificant (0,1-0,8%). Under the influence of herbicidal treatment and disposal of a significant part of the soil surface from weeds, a decrease in the NDVI index is noted (by 0,07-0,34); the introduction of nitrogen fertilizers influences the increase in the NDVI index (by 0,07-0,08 and 0,13-0,14 at N60 and N120, respectively), due to the growth of the aboveground mass of cultivated and weed plants. Against the background of herbicidal treatment, it is possible to correct the nutritional regime using nitrogen fertilizing and a sufficient forecast of the yield of spring wheat, based on the NDVI values for the stemming and earing phases, respectively. The obtained experimental data will become a framework for improving the theoretical and practical basis for using modern monitoring opportunities to substantiate ways to improve the efficiency of managing the state of soil-plant systems and the production process of grain crops in the North-West of the Russian Federation.

Background: University students have specific risk factors for suicide, necessitating targeted prevention programs. This longitudinal study evaluated the efficacy of the Crisis-management, Anti-stigma, Mental health literacy Program for University Students (CAMPUS) for reduction of risk factors and promotion of preventative behaviors. Methods: A total of 136 medical students attended the CAMPUS as a required course at the University of Tsukuba. The CAMPUS consisted of a lecture and two group sessions covering mental health literacy, self-stigma, and gatekeeper efficacy (e.g., identifying and helping at-risk individuals). The students were asked to role-play based on a movie about gatekeepers and scripts about self stigma and suicide-related issues. Participants completed questionnaires on suicidal behavior, depression, help-seeking intentions, self-efficacy as gatekeepers, self-concealment, and self-acceptance. Results: A total of 121 students completed the questionnaires pre- and post-program, and 107 students also responded 6 months later. Higher-risk students demonstrated significantly reduced suicide risk 6 months post-program compared to before the program. In addition, gatekeeper self-efficacy, help-seeking intentions for formal resources, and self-acceptance were improved in both low and higher-risk students 6 month after the program. Limitations: The CAMPUS program was delivered as a mandatory requirement to a group with high scholastic abilities and relatively low suicide risk. Further studies are required to assess its suitability for the general university student population. Conclusions: The CAMPUS proved effective at reducing risk factors for suicide and promoting preventative behaviors among university students.
