Authors: H Adamu, , M Jabbi, A. , N Aliyu, H.
Published: May 2023

Two hydrazone Schiff base was synthesized by the interaction of ethanolic solution of antiglyoxime hydrazine with 2-acetyl-5-methylfuran to obtain the Schiff base. The complexes of Mn(II), Fe(II), Ni(II) and Cu(II) and their Schiff base were synthesized and characterized based on solubility, percentage yield, elemental analysis, melting point and decomposition temperature, infra-red spectra (FT-IR), conductivity measurement, magnetic susceptibility and water of crystallisation. The ligand and the complexes were coloured and stable at room temperature. They were soluble in acetone, DMSO, ethanol, methanol, hexane, chloroform, carbontetrachloride, benzene and DMF but insoluble in distilled water. The melting point temperature of the ligand was 118oC while the decomposition temperatures for the complexes were found to be between 295-312oC. The molar magnetic susceptibility of the complexes were in the range of 3.55 x 10-3 – 1.42 x 10-2erg.G-2mol-1. Molar conductance values of 2.17 – 2.87Ω-1cm2mol-1 show non electrolytic nature of the complexes. The spectral data of the ligand showed bands in the range 1581–1607cm-1 revealing the formation of the azomethine group. A band between 760-795cm-1 indicates the metal nitrogen bonds. The elemental analysis of the complexes showed the metal ligand ratio of 1:2 (M:2L). The antibacterial and antifungal studies showed that the complexes exhibited higher antibacterial and antifungal activities than the ligand but lower than the reference drugs.
Global Conflict Escalation during the Pandemic, Climate, and Economic Dilemmas: Healthcare Sustainability Challenges in Conflict Zones and Elsewhere
Authors: Mohiuddin Abdul Kader
Published: May 2023

Religion, governance, and politics—as well as related topics such as human rights, justice, and so on—have historically caused many of the world's most significant conflicts, and they continue to do so because these issues are often the most fundamental in the structure of a society. To gain a military advantage, parties to armed conflicts have polluted water, burned crops, cut down forests, poisoned soils, and killed animals over the years. A variety of context factors, particularly socioeconomic conditions, governance, and political factors, interact and play a key role in translating climate change into conflict risks. The present unrest all over the world risks putting more than half of the countries into a crisis of health, economy, and social safety, which is the biggest threat to human civilization. The security and safety of healthcare facilities, workers, and supply lines remain paramount concerns along with access to health services, technology, and innovation.
Cultural Tension and Artistic Mediation in Uwemedimo Atakpo’s Return to the Sun-god.
Authors: Akpan Kufre A.
Published: May 2023

This paper examines cultural tension as pervasive thematic thrust in Uwemedimo Atakpo’s Return to the Sun-god and also extrapolates the playwright’s creative tool for conciliation of the socio-cultural crisis that pervades the sphere of this enactment. The paper notes that religious and other socio-political upheaval are inevitable in almost every society that witnesses cross-cultural influences. This usually arises when there is a deliberate intention to downplay an extant culture of a particular community in preference for the cultural values of a predatory power, thereby causing fundamental modifications of natural condition that lends a valid identity to a particular community. This development, most times, impinges on the socio-political and religious wellbeing of the people whose culture is being suppressed. It is against this backdrop that this paper examines some threads of cultural tension in the play under examination. Through the analysis of the text, this paper does not only isolate instances of cultural tension in the text, but also explores some possible avenues through which the playwright diffuses the unwarranted consequences of the inter-cultural contact. The paper concludes that change and other social eruptions are natural imperatives of man and should not be viewed as destructive but should rather be harnessed towards meeting the myriad challenges of life. Keywords: Culture, Tension, Playwright, Change, Mediation.
Molecular Mechanistic Insight Spirulina as Anti-stress Agent
Authors: Mishra Priyank , Kumar Sunil , Malik Jitender K.
Published: May 2023

When under stress, our body reacts by releasing hormones and triggering the nervous system. The hypothalamic-pituitary-adrenal axis, which transmits the stress response, is in charge of the neuroendocrine adaptation of the stress response. Corticotrophin releasing hormone neurons control hypothalamic-pituitary-adrenal function Increased. Many metabolic and neurological problems linked to stress are associated with the synthesis of corticotrophin releasing hormone. Gamma-aminobutyric acid (GABA) and GABAergic inhibition both play a significant role in controlling the activity of CRH neurons. Several synthetic medicines that target the GABAa receptor and activate GABAa activity are used to lessen the effects of stress. These treatments have relaxing effects but also come with a variety of negative effects. As they have no adverse effects and are harmless, anti-stress herbs are utilised as an alternative therapy to help the adrenal system. Spirulina platensis (commonly referred to as ‘Spirulina’), are well for their Immune system modulation; anti-viral activity; cancer preventive properties, and cardiovascular benefits. In present work an attempt had been made to evaluate the anti-stress potential of active constituent of spirulina by molecular docking.
Ageing and Insulin: Inter Alia Diabetes, Obesity and Fitness Concerns
Authors: Sr Chrysanthus Chukwuma
Published: May 2023

This article argues the essence of insulin sensitivity versus secretion including insulin resistance in the clinical strategy for the treatment, lifestyle changes, prompt interventions and control of diabetes. Progressive decline of glucose tolerance as advanced age occurs has been associated with the pathogenesis of type 2 diabetes due to peripheral insulin resistance and impaired β cell function. In elderly persons, insulin secretion is deranged concomitantly with decreased insulin clearance rate and augmented circulating proinsulin level that ostensibly explicates age-related hyperglycemia. Insulin is associated with numerous pathophysiological processes exhibited during brain function in learning and memory, as well as the regulation of ageing, metabolic syndrome, obesity, diabetes and cardiovascular diseases in Man. Elevated chronic peripheral insulin, decreased insulin action and brain insulin contents are pathognomonic of the insulin resistance syndrome. All these are associated through specific mechanisms in the pathophysiology of ageing and insulin in concert with risk factors and the concomitant complications. Ostensibly, progressive excess insulin induces synchronous elevated levels of oxidative stress and inflammatory impacts which exacerbate or are exacerbated by advancing age, culminating as inimical consequences to healthy lifestyles, longevity or extended lifespan. Therapeutics and other healthcare measures may be beneficial in order to prevent, mitigate or amend insulin aberrations in the elderly and during the ageing process. The mainstay in managing an elderly patient with perturbed insulin action, is control of therapeutic application, as it can reverse acute terminal states. Treatment necessitates stringent and thorough expertise, knowledge and skills for optimum provision and effective cerebral, cardiovascular and skeletal protection for a healthier lifespan and longevity. This article will be of immense contribution in the understanding of the prevention, control and treatment of insulin resistance, metabolic syndrome, diabetes, obesity, cardiovascular and neurological disorders during ageing.
The Power Optimization and an Area Efficient of Static RAM 1-Bit Cell using CMOS Novel Technologies
Authors: Sahruday Gaje , Srikanth Anumula , Harikrishna Karne
Published: May 2023

In order to meet all the expectations of consumers, today's technology is all equipped with large capacity memories. Additional factors include power consumption and delay, all of which are crucial in determining how well a gadget performs. Memory is an important factor of many widgets, and as devices get smaller, their size likewise gets less. Every computerized device, as a result, uses little power, and speed is of utmost importance. Since 6T Static Random Access Memory (SRAM) cells have advantages over other cells, the current scenario suggests that they are frequently employed for SRAM-based memory systems. Today's electronics businesses are primarily concerned with minimizing power consumption, with static and dynamic power dissipation being the two key considerations. Meeting customer demands, high bandwidth, low power, and fast-consuming storages are also required. The major objective of this research is to decrease the power dissipation of the SRAM. The main problem faced by the digital industry is the decrease of power and delay. By connecting two Complementary MOSFET inverters back-to-back, an SRAM cell can be set up in an easy and beneficial manner. This setup offers good noise immunity.

MODEL FOR ASSESSING THE LEVEL OF ECONOMIC PROTECTION OF THE INTERESTS OF A NON-PROFIT ORGANIZATION
Authors:   Graduate student, Russian Presidential Academy of National Economy and Public Administration, Moscow (Russia), Ilyin Petr A.
Published: May 2023

the presence of structural changes in the world economy, the consequences of sanitary and epidemiological restrictions, as well as the increase in international tension with the transition to armed conflicts near the borders of the Russian Federation force us to formulate criteria and possibilities for protecting the economic interests of the population and the state. At the same time. The relevance of the topic is due to the need to study the issues of ensuring the security of the economic interests of non-profit organizations, since in the conditions of rapid changes in the situation, it is these enterprises, including those with state participation, that in many ways allow them to implement the above-mentioned tasks without the purpose of extracting profit from their activities. In the course of research, a general model for assessing the level of economic protection of the interests of non-profit organizations has been proposed, which has the form: Y=β0+β1*X1+β2*X2+β3*X3+β4*X4+ε. The peculiarity of the author's approach to the formation of the model is that as factors affecting the level of economic protection of the interests of a non-profit organization, the model included not only financial indicators, but also indicators showing the personnel and management status. The overall level of economic security, indicated by the dependent variable Y, is influenced by factors X1 (expenditure level), X2 (property security), X3 (personnel) and X4 (managerial) potential. According to the results of the study, during which the analysis of randomly modeled data was carried out, evaluated depending on the specified criteria in the score assessment included in the general model, a private model of the form Ŷ=0,408+0,349∙X1+0,482∙X3 was obtained. A study of the general model, as well as the included variables, was conducted, as a result of which, with a significance level equal to 0.01, the level of expenses and the personnel potential of the organization were significant. The obtained research results can be applied in practice by administrative and statistical services of enterprises and state bodies.

In the work, the movement of the stock market in different countries during the crisis year of 2020 was studied, which did not depend on the decisions made in this country, but obeyed the general trend. In particular, the behavior of sectoral indices of different countries during the first year of the coronavirus was studied and it was concluded that the movement of markets is subject to the global trend. For the analysis, sectoral indices of countries affected to varying degrees by the coronavirus were selected, whose securities markets received various support measures: the United States, Russia, China, Japan and Germany. The impact of the pandemic on industries such as financial services, metallurgy, chemicals, consumer goods and telecommunications is considered. Quotes are considered for the period from 01/01/2020 to 12/31/2020. Graphs of the values of sectoral indices of the Russian Federation and the USA in the specified period are presented and analyzed. Graphs are built in the Jupyter Notebook environment using the Python language and the plotly data visualization library. The concept of hypothesis and criterion is defined and the most important definitions are given. With a decrease in the probability of making a type 1 error, the probability of making a type 2 error increases, so the significance level is chosen so that the power of the criterion is maximum. To test the hypothesis, we used the multivariate KruskalWallis test and its modified version for mediumsized samples with a significance level of α=0.05. The novelty of the study lies in the application of the KruskalWallis criterion to financial data. The study was conducted in Python in the Jupyter Notebook environment using the numpy, pandas, itertools, scipy and plotly libraries.

The applicability of probabilistic methods in various fields of science is due to their universality when considering any problem. First of all, using probabilistic methods in system analysis, we can abstractly evaluate various elements or groups of elements in the system, which ultimately gives us an idea of its functioning and possible deviations that arise during the interaction of many elements. Conditional «objectivity» of the final conclusions allows leading engineers, heads of departments and departments to make important and at the same time rational decisions regarding engineering structures, economic systems and other forms of complex structural systems, on the functioning of which most of human life depends at the present time.

The development of artificial intelligence (AI) technologies opens up broad prospects for solving problems in areas that, until recently, seemed accessible only to humans. This trend is forcing a rethinking of fundamental philosophical questions about the material and the ideal. Improving AIbased measurement systems will lead to mass production of different types of such systems with relatively «weak» AI and with «strong» AI. Together these systems will create changes in society, but they will generate social problems. The article shows the effectiveness of measuring system application based on AI in manufacturing, medicine, transport, for assessing the quality of products and services, as well as determining human abilities, etc. Areas of activities are demonstrated that can accelerate the positive results of the new development stage, delay the emergence of related social problems, and facilitate their resolution.

Bu araştırmada Türkiye’de işaret dili eğitimlerinde yaşanan güncel sorunların betimlenmesi amaçlanmaktadır. Verilerin yarı yapılandırılmış görüşme tekniği ile toplandığı bu araştırmada nitel araştırma yöntemlerinden fenomonoloji deseni kullanılmıştır. Araştırmaya Türkiye’nin çeşitli bölgelerinde yaşayan ve Türk işaret dili kurslarında işaret dili eğitimi veren yetişkin işitme yetersizliğine sahip bireyler katılmıştır. Katılımcılar farklı eğitim düzeylerine sahip, işitme kaybı (90 dB üstü) olan iletişim olarak işaret dilini kullanan ve işaret dili eğitmenleridir. Her bir katılımcı ile görüşme ortalama iki saat sürmüştür. Katılımcılara işitme engellilerin eğitimleri ve işaret dili konularında çeşitli sorular yöneltilmiştir. Görüşmelerde elde edilen veriler, içerik analizi ile çözümlenmiştir. Bulgular, Türkiye’de işaret dili eğitmenliği için yasal bir düzenlemenin olmadığını, işaret dili eğitimlerinin çeşitli kurs ve derneklerce verildiğini, işaret dili eğitmenlerine yönelik kriterlerin oluşturulmadığını, Türk işaret dili eğitim uygulamalarında eksik ya da yanlış öğretime sıklıkla rastlandığını göstermektedir. Araştırma kapsamında Türk işaret dilinin kullanımı ve eğitimine yönelik yönelik Millî Eğitim Bakanlığınca politika geliştirmesi, işitme yetersizliği olan bireylerin eğitimine yönelik yöntem konusundaki tereddütlerinin giderilmesi, işaret/sağır kültürünün geliştirilmesi ve korunması için çalışmaların yapılması önerilmiştir.
