Corporate Carbon Footprint Environmental Quality and Combating the Covid-19 Pandemic (US Example)
Authors: KARACAN Rıdvan
Published: February 2022

Objective: Developed countries with high use of fossil fuels in production can harm the environment by contributing more to the formation of greenhouse gases on a global scale. In this context, it has been emphasized that they have caused an increase in Covid-19 cases. Thus, it was desired to present a different perspective to policymakers in the fight against the virus.

Methods: This research comprises the United States. The relationship between Coal Industry CO2 (CCO), Natural Gas Industry CO2 (NCO), Power Industry CO2 (ECO), Petroleum Industry CO2 (OCO), and Covid-19 cases (COV) variables is discussed. Monthly data for the period 2019-2021 were used. The data were compiled from World Health Organization and Our World in Data web resources. In the analyses, the ARDL Boundary Test model was used to capture long and short term causality relationships.

Results: In general, it shows that fossil energy sources such as coal, oil, electricity and natural gas used in industries play an important role in the increase of Covid-19 cases. Among these energy sources, coal is the one that causes the most effect. Coal is followed by oil, electricity and natural gas, respectively. Accordingly, a 1% change in the US economy due to coal used in production leads to a 1.03% change in Covid-19 cases. Similarly, the effect of oil on Covid-19 cases is 0.61%. The impact of industries using electrical energy based on fossil fuels in their production in Covid-19 cases is 0.26%. It has been determined that the fossil fuel energy source with the least effect with a change of 0.069% in Covid-19 cases is natural gas.

Conclusions: The findings revealed that the increase in fossil fuels used in industries during the relevant period adversely affected air quality and Covid-19 cases. The increase in the number of cases affects the health sector more than other sectors. If these data are associated with energy sources used in industries (fossil fuels) in the future, they will contribute to the creation of public policies that encourage a new generation of energy sources in production.

The widespread use of antibacterial drugs for the treatment of respiratory diseases causes antimicrobial resistance in opportunistic microorganisms, which leads to the chronic forms of respiratory diseases and contributes to the risk of repeated respiratory infections. One of the new therapeutic solutions is the use of multicomponent water-soluble plant extracts. The goal of this study was to evaluate the antibacterial efficacy of the extracts of multicomponent herbal remedies versus the synthetic antiseptic for the treatment of the oropharyngeal and gut opportunistic microflora in children with chronic tonsillitis.

In a retrospective study, we compared the effectiveness of the plant extract Tonzinal (experimental group, 100 patients) versus the Miramistin antiseptic agent (control group, 40 patients) for the treatment of chronic tonsillitis in children 5 to 15 years old using various treatment regimens.

The oropharyngeal microbiocenosis was investigated by the bacteriological analysis of smears from the posterior wall of the pharynx and tonsils. Bacterial strains were isolated by inoculation on liquid agar media with the subsequent identification of Staphylococcus aureus, Streptococcus pyogenes, Candida spp., Moraxela cataralis, and Mycoplasma pneumonie according to the morphological and biochemical characteristics. For the bacteriological analysis of gut microbiocenosis, Staphylococcus aureus, Streptococcus spp., Candida spp., Klebsiella spp., Clostridiums spp., and Proteus spp. were isolated from the fecal filtrate and then identified by the same methods. The occurrence rate of microorganisms in patients of the experimental and control groups was compared before and after the 10-day course of therapy.

A statistically significant decrease in the occurrence rate of Staphylococcus aureus (from 25% to 0%, p<0.01) and Candida spp. (from 18% to 0%, p<0.01) in the oropharynx of patients in the experimental group and from 20% to 7.5% and from 5% to 0% (p<0.05), respectively, in the control group was observed. A statistically significant decrease in the occurrence rate of Streptococcus pyogenes was only observed in the experimental group (from 30% to 0%, p<0.01). Treatment with Tonzinal or Miramistin did not lead to the statistically significant changes in the occurrence rate of opportunistic microorganisms in the gut microflora of the patients in both groups.

Therefore, we have shown a higher antimicrobial efficacy of Tonzinal versus the Miramistin antiseptic for the treatment of the oropharyngeal opportunistic microorganisms in children with chronic tonsillitis.

Published: February 2022

Euphorbia hyssopifolia L. is an annual herb producing toxic latex. To our knowledge, this study is the first one that focuses on accurately identifying the bioactive compounds in E. hyssopifolia and evaluating its antioxidant and anti-breast cancer activities. Phytochemical qualitative screening tests were performed. Total phenolic contents (TPC) and total flavonoid contents (TFC) were determined by Folin Ciocalteu and Aluminum chloride methods, respectively. Bioactive compounds in E. hyssopifolia latex were identified by using GC-MS analysis. Antioxidant activity was evaluated using DPPH and ABTS assays, and anticancer activity of latex against MDA-MB-231 breast cancer cell line was studied using flow cytometry methods. Results revealed the presence of flavonoids, tannins, alkaloids, diterpenes, steroids, and cardiac glycosides in the plant, whereas saponins were absent. Latex outperformed methanolic 70% extract in terms of TPC and TFC (39.52 ± 0.36 mg GAE/g E and 28.66 ± 0.10 mg RE/g E, respectively). GC-MS analysis of E. hyssopifolia latex resulted in the identification of 26 compounds, of which triterpenoids constitute 67.0172%, followed by lupeol (23.7089%) and betulin (14.0098%). According to the reference studies, most of the compounds found in latex have many biological activities. Latex outperformed all extracts and ascorbic acid in terms of antioxidant activity (IC50= 0.029 mg/mL for DPPH, IC50= 0.001 mg/mL for ABTS). Flow cytometry methods revealed that E. hyssopifolia latex induced cell cycle arrest at G1 phase (61%) and apoptosis (21.93%) of MDA-MB-231 cells after treating with latex at 10 µg/mL for 24 hours. However, more studies should be performed to explore bioactive compounds in E. hyssopifolia and determine the underlying mechanism of its latex anti-breast cancer effects.

RESSIGNIFICAÇÕES DO PASSADO PELA LITERATURA HÍBRIDA JUVENIL A Assinatura da Lei Áurea “libertação” dos escravos no Brasil- Oficinas Literárias
Authors: Saldanha Fant Carla Cristina , Oliveira Marcio da Silva , Scopel da Silva Rosângela Margarete
Published: February 2022

A leitura literária possibilita a construção de sentidos sobre o mundo e a interpretação desse universo em determinado contexto. O resultado dessas ações pode ser diferente para cada leitor. Este vai descobrir um sentido para o que lê e uma maneira de desvendar o texto a seu modo, pois a compreensão sobre leitura vai além do que está escrito, é um processo que depende de conhecimentos e interesses prévios ao ato da leitura. Por isso, propomo-nos a estabelecer reflexões sobre a formação do leitor literário nos anos finais do Ensino Fundamental e apresentar uma metodologia que se efetiva por meio de “Oficinas literárias temáticas” que abordam “Ressignificações do Segundo Reinado do Brasil”, mais especificamente no que se refere ao processo de escravidão, refletindo sobre narrativas híbridas de história e ficção. Para alçar tais objetivos, ancoramo-nos em conceitos fundamentais que permeiam abordagens referentes à formação do leitor literário e ao papel humanizador e transformador da literatura, como destacados em Candido (1972; 2011), Jauss (1979), Mendoza Fillola (1994), Fleck (2007; 2017; 2019), Zucki (2015) entre outros. Além disso, com a valorização da leitura literária em sala de aula, procuramos fundamentar uma perspectiva descolonizadora a respeito dos eventos históricos desse contexto acima mencionado, de modo a desconstruir certos conceitos arraigados na sociedade, tais como heroísmo, progresso e desenvolvimento e apontar uma valorização das vozes marginalizadas, vítimas de violência e exploração e ainda hoje vistas de forma discriminatória pela sociedade hegemônica.
MI SIMÓN BOLÍVAR (1930)
Authors: Dorado Mendez Hugo Eliecer , De Jesus Silva Rosangela , Fleck Gilmei Francisco
Published: February 2022

Neste artigo, buscamos evidenciar como o romance Mi Simón Bolivar ([1930] 2002), do colombiano Fernando González Ochoa, redimensiona a configuração discursiva da personagem histórica Simón Bolívar – consagrada, heroificada e sacralizada tanto na historiografia nacionalista positivista como na literatura romântica do século XIX – a uma ressignificação crítica dessas imagens idealizadas. A hipótese aqui defendida é de que a obra de González Ochoa é a precursora da que viria a ser considerada a segunda fase da trajetória do romance histórico, constituída pelas modalidades do novo romance histórico latino-americano e da metaficção historiográfica. Ancorados nos pressupostos de Aínsa (1991), Menton (1993) e Fleck (2017), destacamos como o romance de González Ochoa antecipa as características da modalidade crítica do novo romance histórico latino-americano, pelo emprego da paródia, da carnavalização, das intertextualidades e dos recursos metanarrativos. Desse modo, podemos afirmar que foi essa a obra que abriu, na América Latina, uma das vias mais profícuas de ressignificação do passado, uma via à descolonização do ser e do saber, assim como à prática efetiva das ações decoloniais.

O presente estudo tenciona uma análise acerca de três personalidades históricas, cuja representatividade foi marcada de forma ex-cêntrica frente ao discurso hegemônico de cunho positivista. As produções escolhidas são: Colón a los ojos de Beatriz (2000), de Pedro Piqueras, Our Lives Are the Rivers (2006), escrita por Jaime Manrique, e A descoberta do Novo Mundo (2013), de Mary Del Priore. Os referidos romances atuam em uma perspectiva mediativa, segundo Fleck (2017), entre as abordagens tradicionais e desconstrucionistas acerca dos modos de perfilar o passado histórico.
RESSIGNIFICAÇÕES DE ANACAONA NA LITERATURA INFANTOJUVENIL HAITIANA:
Authors: Lopes de  Almeida Carlos Henrique , Sant’Ana Michele de Fátima , Becher Tatiane Cristina
Published: February 2022

Neste artigo, pretendemos demonstrar que, apesar de não figurar nos anais da história tradicional como personagem feminina resiliente, a atuação de Anacaona – cacica taína da ilha de Guanahaní – representou significativamente os enfrentamentos indígenas perante a exploração espanhola no período da colonização da América. Para isso, realizamos a análise comparativa de uma das ressignificações de Anacaona na literatura infantojuvenil haitiana: Anacaona, Ayiti's Taino Queen/Anacaona, La Reine Taino D'Ayiti (2012), de Maryse Noël Roumain. A narrativa híbrida foi comparada com registros reconhecidos da historiografia tradicional. Para tanto, baseamo-nos nas teorias de autores como Zilbermann (1985), Coelho (2010), Luft (2010) e Fleck (2017).
In this article, we intend to demonstrate that, despite not appearing in the annals of traditional history as a resilient female character, the actions of Anacaona – taino cacica of the island of Guanahaní – significantly represented indigenous confrontations with Spanish exploitation in the period of colonization of America. For this, we carried out a comparative analysis of one of the re-meanings of Anacaona in Haitian injant-juvenile literature: Anacaona, Ayiti's Taino Queen/Anacaona, La Reine Taino D'Ayiti (2012), by Maryse Noël Roumain. The hybrid narrative was compared with recognized records from traditional historiography. In order to do that, we base ourselves on the theories of authors such as Zilbermann (1985), Coelho (2010), Luft (2010) and Fleck (2017).

Este artigo analisa o romance histórico contemporâneo de mediação Terra Vermelha ([1998], 2013), de Domingos Pellegrini, em contraste com outras narrativas paranaenses –Quatro Gerações (2018), de Ivo Pegoraro, e O trovador (2014), de Rodrigo Garcia Lopes – com o objetivo de evidenciar como a arte literária é capaz de realizar uma releitura crítica sobre a historiografia tradicional, neste caso, sobre o processo de povoamento do norte do Paraná, mais especificamente, de Londrina. Em atenção aos referentes históricos, ancorados na abordagem de Nascimento (2009) e Mendonça (2015), bem como nos pressupostos teóricos de Mata Induráin (1995) e Fleck (2017), buscamos destacar como as narrativas híbridas de história e ficção reatualizam e problematizam o passado perpetuado pela história hegemônica, convidando à reflexão crítica, revisionista e descolonizadora do passado paranaense em especial.
O ROMANCE HISTÓRICO CONTEMPORÂNEO DE MEDIAÇÃO ANA NÉRI, A BRASILEIRA QUE VENCEU A GUERRA (2002)
Authors: Vivian Rosmere Adriana , Fleck Gilmei Francisco
Published: February 2022

As escritas híbridas de história e ficção consideradas romances históricos têm sua trajetória inicial marcada pelos produções do escocês Sir Walter Scott na época do romantismo europeu. Desde sua gênesis esse gênero híbrido vem sofrendo constante mudanças que adaptam essa produção às questões históricas, socias e culturais das diferentes épocas de sua produção. Na atualidade, ela conta com grande êxito de público em uma modalidae específica que Fleck (2007-2008-2011) classifica como romance histórico contemporâneo de mediação. Nosso propósito ao longo deste texto é expor algumas das cararcterístcias dessa modalidade apontadas pelo pesquisador e confirmá-las na leitura do romance Ana Néri, a brasileira que venceu a guerra (2002), de José Louzeiro. Nossa análise dará ênfase ao fato de que essa modalidade de romance histórico mais atual, embora abandone grande parte dos intuitos desconstrucionistas das produções híbridas de história e ficção mais recentes, não deixa de operar uma leitura crítica do passado. No caso da obra de Louzeiro (2002), ela se dá com relação à participação da mulher na Guerra do Paraguai (1864-1870), cuja perspectiva ficcional buscamos compreender.
PALAVRAS-CHAVE: Romance histórico contemporâneo de mediação; Guerra do Paraguai (1864-1870); personagens femininas de extração histórica; José Louzeiro (2002).
A CONSTRUÇÃO DA IDENTIDADE DE ARAMIDES FLORENÇA.
Authors: Fernandes Camilla , Rodella Abriata Vera Lucia
Published: February 2022

“Aramides Florença” (EVARISTO, 2016) relata a história de uma mulher que gradativamente se conscientiza da violência física e psicológica que sofre do companheiro.   Utilizamos o instrumental teórico da semiótica francesa com vistas a apreender as estratégias utilizadas na construção da identidade do ator feminino, por meio da análise de seu percurso. Observamos no nível do enunciado as relações polêmicas que Aramides estabelece com o pai de seu filho e as paixões que a acometem.  No presente da enunciação, por outro lado, já liberta da opressão sofrida, o ator conta sua história à narradora que simula recriá-la em suas escrevivências.
AUTOFAGIA, ENREDO E DESENREDO EM A RAINHA DOS CÁRCERES DA GRÉCIA, DE OSMAN LINS
Authors: Brandão de oliveira Amaral Leonardo
Published: February 2022

Este trabalho, fundamentado nos conceitos propostos por Mikhail Bakhtin, empreende uma leitura de A rainha dos cárceres da Grécia, de Osman Lins, com o objetivo de demonstrar sua construção arquitetônica. Para tal, analisam-se as construções composicionais que realizam a forma arquitetônica, elencando como fundamentais à sua leitura crítica: a teorização estética realizada pela própria narrativa; a configuração do enredo em uma forma dissimuladora de sua literariedade e o processo de desenredo, operado e conceituado pelo próprio narrador. Nota-se que a obra se realiza arquitetonicamente como uma autofagia crítica, um romance que tenta explicar-se, completar-se em todos seus momentos.

En el presente artículo se analizan la “Alocución a la poesía” (1823) y “La agricultura de la zona tórrida” (1826) de Andrés Bello bajo la noción de poema histórico (LÓPEZ; PÉREZ ANZOLA; SAAVEDRA, 2021), modalidad híbrida del género poético entre historia y ficción que funciona discursivamente con las mismas características de la novela histórica crítica/deconstruccionista (FLECK, 2017): ofreciendo resignificaciones alternativas y/o cuestionadoras del discurso historiográfico oficial. El foco del análisis se centra en describir el locus enunciativo del Bello poeta en correspondencia con las versiones historiográficas sobre el Bello histórico como personaje vinculado al proceso de la independencia de América.
Competitive Conditions and Banking Stability in Pakistan: New Evidence from Market Power and Charter Value
Authors: Aleemi Abdur Rahman , Uddin Imam , Kashif Muhammad
Published: February 2022

In this study, we invoke the theoretical notion of different competitive conditions in lending and deposit market power for the banking industry of Pakistan. We find highly monopolistic conditions in lending market whereby majority of the banks are enjoying high market power. On the other hand, the deposit market is found to be highly competitive. Subsequently, we find the effects of the lending and deposit market measures of market power on the riskiness of banks to be asymmetric. In addition, we introduce charter value as a determinant of banks’ risk for the first time in the case of Pakistan and tested for whether or not greater higher valuable charters enhance the risk aversive tendencies of banks to preserve charter value? Our findings suggest that the theoretical link between charter value and market power is sufficiently strong to restrain risky behavior of banks.
Applicant Attraction towards the Organization with the Moderation Effect of Gender: A Perception of Business Students
Authors: Mir Muhammad Masood , Amin Hina , Omar Mohammad , Khan Sahar
Published: February 2022

Talent attraction is contemporarily subject to extensive research due to prevalent gaps which hold significance in the field of human resource management. This article describes how students graduating from a business school in Karachi, Pakistan perceive various organizational factors in terms of their impact on the attractiveness of the firm as a place to work. The framework used in the study included exogenous constructs depicting compensation, both direct and indirect, along with Corporate social responsibility, both internal and external in organizations. The influences of both compensation and CSR on organizational attractiveness were examined in the study. The segregation of respondents in terms of gender was used as a moderator. The moderating influence of gender segregation on the relationship between exogenous and endogenous constructs was also examined in this paper. In the study 130 responses were received and 112 were found suitable for the analysis. The results were analyzed on SMART PLS software by using latest techniques. The findings of the study demonstrated that compensation is the significant factor attracting business school talent, while gender moderated the impact of both compensation and CSR activities on workplace attractiveness. Specifically, males prefer extrinsic direct and indirect compensation and no impact of CSR found to attract them. Extrinsic indirect compensation and internal CSR activities were positively related to workplace attractiveness for women than for men. Implementing these practices appropriately given the context is likely to benefit the firm by attracting talented employees. The study is limited to only business institutes of Karachi which can be extended to other cities and institutes in future for the better results and generalizability.
Factors Affecting Small and Medium-Sized Enterprises’ Accessibility to Institutional Finance in Pakistan: Moderating Role of Government Support
Authors: Khaliq Abubakar , Islam Muhammad Saif Ul , Akram Muhammad , Hussain Aamir , Usman Muhammad
Published: February 2022

The study aims to explore the factors influencing the accessibility of small and medium-sized enterprises to institutional finance and moderating role of government supports in the relationship between collateral security, interest rates, financial information, business ownership, and accessibility to finance facilities in Pakistan. The moderation multiple regression analysis was applied for analysis using SMART PLS3.0 software. A fully structured questionnaire is used for gathering data or information from the respondents. The results showed that all the variables are directly and significantly influencing access to finance except interest rates, but interest rates indirectly affect the dependent. The government support does moderate in the interaction between collateral security, interest rate, and financial accessibility. On the other hand, the variable doesn't quite moderate the interaction between financial information, business ownership, and financial accessibility in Pakistan. This research aimed at making access to finance services essentially helpful to the SME industry by knowing what impacts their financial accessibility and helping lending institutions in understanding what effectively prevents the SME industry from accessing finance-related services in Pakistan.

Authors: Gadzhiev Kh. M. , Akimov A. A. , Abdurafikov E. A. , Asaliev R. Sh. , Magomedov A. M.
Published: February 2022

Objective. The aim of the study is to simulate resonators for microwave digital active phased antenna arrays (DFAAR) in the microwave range, which will optimize the parameters of the antenna system for more reliable direction finding with high reliability of any aircraft. Method. The use of one-sided surfaces in the Mobius shape as resonators makes it possible to implement a new type of microwave resonators in the form of an integrated capacitance and a two-turn inductance. The parameters of such a resonator make it possible to realize a traveling or standing wave, depending on the geometric dimensions. Result. The use of innovative resonators for microwave DFAAR with p-i-n diodes to change the area of the capacitor makes it possible to implement a two-frequency method of pulse-code modulation. On the basis of such resonators, it is possible to realize a standing wave at one position of the p-i-n diodes, and a traveling wave at the other. Such electromagnetic waves, transmitted by the DFAAR, can track objects in the stealth mode. Conclusion. The use of traditional resonators for DFAAR of the microwave range allows you to discretely adjust the parameters of these resonators by turning on / off p-i-n diodes with positive and negative voltages to control the frequency properties of the resonators and set the traveling or standing wave modes.

Authors: Murtazaliev G. M. , Paizulaev M. M.
Published: February 2022

Objective. The purpose of the study is to determine the group of the limiting state according to the condition of loss of stability of the equilibrium form of structures. Method. The study is based on the provisions of the theory of stability of equilibrium states of building structures; branching theory of solutions of nonlinear equations; perturbation method; methods of catastrophe theory.Result. The results of the analysis of the post-critical behavior of structures based on the solution of the problem in higher approximations and from the fundamental provisions of the theory of catastrophes are generalized. It is proved that the study of the stability of equilibrium forms of structures using algebraic means and geometric images of the theory of catastrophes makes it possible to unambiguously determine the type of critical bifurcation points, predict the nature of the behavior of the structure, and determine the limit state group to which the state reached by the structure should be attributed. Conclusion. It seems necessary to rename the ordinal numbers of the types of critical points of bifurcations so that they coincide with the numbers of the groups of limit states corresponding to them.

Authors: Salamanova M. Sh.
Published: February 2022

Objective. The problems of the negative impact of the carbonate technology for the production of Portland cement are hotly discussed at many scientific sites and the world community is striving to create more environmentally friendly and less energy-intensive binders. The development of clinker-free technology will allow solving many problems of a global scale, and the use of recycled or substandard material will expand the raw material base and reduce the burden on the environment.Method. When designing formulations for building mortars, it is necessary to take into account the compliance with the requirements for all mortars in general, both for plastering and for masonry, finishing, repair, etc. The study of the compositions of mortars was carried out by standard methods using a verified and certified equipment. Result. The paper presents the results of many years of work on the development of building composites based on binders of alkaline activation. Grades of solutions M75 - 150 were obtained, with the mobility of the mortar mixture Pk 1-2, shelf life of 33-120 minutes, with high adhesive strength of 0.62- 0.71 MPa. Conclusion. The proposed mortar compositions will make it possible to perform plastering, masonry and repair work requiring quick setting, and with proper adherence to the proposed recipes and methods for making mortars, it will be possible to obtain high-quality and durable material.

Published: February 2022

Objective. The aim of the study is to study the effect of preliminary electrical heating of the concrete mixture on the structure and properties of heat-resistant expanded clay concrete on a composite binder before drying at a temperature of 105°C. Method. It is based on domestic and foreign experience in studying the effect of preliminary electrical heating on the properties and structure of various concretes, including heat-resistant ones. Result. A laboratory stand for preliminary electrical heating of mixtures has been developed and tested. The influence of preliminary electric heating on the process of self-steaming of heat-resistant expanded clay concrete has been studied. A mode of preliminary electric heating of a heat-resistant expanded clay concrete mixture in time has been developed. Stress dependences are obtained due to the difference in the temperature coefficients of linear expansion of coarse and fine aggregates and the mortar part on the heating temperature, as well as the dependences of the ultimate strength of expanded clay concrete on the heating temperature of the expanded clay concrete mixture under various modes of preheating with a composite binder with a ratio of components: Portland cement 70%, mineral additive 30%. Conclusion. Based on the results obtained and the analysis of the studies carried out in the field of preliminary electrical heating of concrete mixtures, it can be concluded that the preliminary electrical heating of a mixture for heatresistant concrete with expanded clay filler based on an activated composite binder will make it possible to obtain concrete with higher physico-thermal and operational characteristics, as well as to reduce the technological process of manufacturing heat-resistant products, the drying period and bringing the thermal unit to the operating mode.

Authors: Hasanov T. G. , Batmanov E. Z. , Guseinov M. R.
Published: February 2022

Objective. The aim of the study is the possibility of obtaining the impedance of the controlled and interfering parameters using the example of a capacitor sensor. Method. The study is based on the determination of the analytical relationship between the change in the impedance of the sensor and the frequency of the current in which the capacitance of the capacitor is excited. Result. Having determined the resistance of individual circuit elements, you can find the impedance of the equivalent circuit at any fixed frequency. An equation for the impedance of the sensor is obtained, reflecting the dependence of the output signal on the change in both the controlled humidity and the interfering parameter - the dielectric constant of oil at any frequency in the studied range. The existence of the frequency parameter for the separation of information contained in the output signal of the measuring circuit has been proved. Conclusion. If the parametric separation of the signal is possible, the output value of the sensor can be automatically corrected for the change in the dielectric constant of the "dry" oil, and continuous measurement of the controlled moisture can be carried out.

Objective.The purpose of the article is to highlight the results of experimental studies, the measurement technique, as well as the design of a laboratory stand for carrying out field tests of a thermoelectric device (TEC) for stopping bleeding by the method of local freezing of the blood flow zone.Method.An experimental stand and a technique for carrying out measurements of a laboratory sample of a TEU for stopping bleeding by the method of local freezing of the blood flow zone are described. The experimental stand is made on the basis of the measuring equipment of the laboratory of semiconductor thermoelectric devices and devices of Daghestan State Technical University.Result.The graphs of the time dependence of the temperature change of the control points of the laboratory sample of TEC for stopping bleeding by the method of local freezing of the blood flow zone at various supply currents of the thermoelectric battery (TEB) were obtained. The control points were cold and hot junctions of TEB, a simulator of a biological object.Conclusion.The data obtained show that with an increase in the area of blood flow, it takes more time to stop it. An increase in the diameter of the hole with blood flow by an average of 1 mm increases the duration of thrombus formation, which stops bleeding by an average of 20 s. During the experiment, it was found that to ensure the efficient operation of the TEU, it is sufficient to use the commercially available TEB brand ICE- 71.

Objective. The aim of the study is to generalize the accumulated experience of fuzzy situational control based on a compositional hybrid model of a complex technical system in the form of an algorithm and, on this basis, to form recommendations on the methodology for the formation and identification of situations, determining parameters and solutions for managing a complex technical system under conditions incomplete data to improve the accuracy of control decisions. Method. The use of a compositional hybrid model solves the problem of describing and modeling the system in conditions of incomplete data and the impossibility of obtaining information about the entire range of the system's operation. Fuzzy situational control makes it possible to develop control decisions in accordance with the chosen control strategy and take into account the specifics of the system thanks to the compositional model. Result. An algorithm for fuzzy situational control of complex technical systems based on compositional hybrid models is proposed. The stages, features, advantages and disadvantages of fuzzy situational control for this type of systems are considered. The procedure for determining and unambiguously identifying emerging fuzzy situations for the system is given, and a method for analyzing and developing typical control strategies is also considered. The compositional hybrid model of a complex technical system considered in the article describes the operation of the experimental compressor unit ETsK-55. Conclusion. The main advantages of the developed fuzzy situational method for managing complex technical systems include: integration of the control system with existing elements of the system; better use of available resources; adaptability and reliability of a control method based on fuzzy situational networks and a composite hybrid model of the system. Management strategies have been defined to meet the customer's requirements for product quality, as well as the safety of personnel and equipment, trouble-free production and saving resources.

Objective. The existing approach to assessing the publication activity of scientific, higher educational institutions and scientists (including through the Russian Scientific Citation Index) does not reflect the true effectiveness of their scientific activities. Key indicators for assessing publication activity - the citation index and the Hirsch index are formed on the basis of the data provided by the RSCI and cannot reliably establish the authorship of the publication, the contribution of each coauthor, and the methodology for accruing indicators of scientific activity requires serious adjustment and improvement. The existing methodology for assessing publication activity stimulates multiple coauthorship in publications, to which the co-authors are often not directly related, which distorts the science-metric indicators, stimulates immutation science and increases citation indicators due to unjustified self-citation. In this regard, the subject of the study is the state of scientifometry and the methods used to evaluate publication activity. The aim of the study is to develop a methodology for assessing the publication activity of authors and organizations. Method. As a method of research, system analysis, geometric modeling, and mathematical calculations are used. Result. As a result, a methodology for evaluating scientifometric indicators was developed, a methodology for calculating a new index of publication activity was developed, a geometric and mathematical model of the new index was presented. Conclusion. The developed index of publication activity makes it possible to more accurately take into account all indicators of the effectiveness of scientific activity: the credibility of the journal and the author, the total number of citations; co-authorship; publication activity of the last five years, etc.

Objective: The present work aim was “A solubility enhancement of aceclofenac by new crystallization technique.” Aceclofenac is non-steroidal anti-inflammatory drug comes under bio-pharmaceutics classification system Class II with low solubility and high permeability. The aim of the study was to study the solubility and dissolution rate of the pure drug and prepared crystals at different temperature.
Methods: Crystal of aceclofenac was prepared by antisolvent sonocrystallization technique.
Results: A different crystal was prepared by Antisolvent sonocrystallization technique. The effect of solvents, temperature, and sonication was investigated. All the formulation was studied the dissolution behavior, MDT, %DE, and solid state characterization such as differential scanning calorimetry (DSC), X-ray diffraction (XRD), and scanning electron microscopy (SEM).
Conclusion: The solubility and dissolution rate of the prepared crystals were significantly higher than pure drug. The prepared crystals in ethanol at temperature 60°C±1°C showed the highest of the solubility of drug at 60 min. Among the prepared aceclofenac, crystals at 60 were showed better results with respect to MDT and %DE when compared to preparation of crystals at 10°±1°C and 25±1°C. DSC studies showed that there was no appreciable change in the melting endotherm of prepared crystals compared to that of pure drug. Powder XRD of prepared crystals at different temperature shows increases intensity of peaks compared to pure drug. SEM studies indicated that prepared crystals at different temperature using sonication shows are sharp needle in shape with crystalline surface compared to pure drug. The results indicate that antisolvent sonocrystallization serves as a successful strategy for enhancing poorly water soluble drug.
