Authors:   Chernivtsi Institute of Trade and Economics of KNUTE, Chornovol Аlla , Tomniuk Tetіana
Published: May 2022

The global pandemic of 2020-2021, caused by COVID-19, brought the greatest global crisis in the world economy since the Great Depression of 1929-1933. In such circumstances, the issue of financial support for business is extremely acute. The purpose of the article is to investigate the modern tools of the state financial policy of Ukraine under the conditions of a pandemic, to determine the necessary corrective measures to increase its efficiency. In the process of research the general scientific theoretical methods were used: methods of structural-logical, conceptual analysis, synthesis - for the implementation of theoretical generalizations and conclusions about the instruments of state financial support of the Ukrainian economy against the impact of the pandemic; graphic method - for visual presentation of theoretical and analytical material on the research topic; inductions and deductions - when setting priorities and restrictions in using financial instruments for eliminating the negative impact of the pandemic on the Ukrainian economy. The work identifies unsatisfactory factors that accompany business processes in modern conditions of the distorted business model caused by the pandemic. The instruments of state financial support to the economy against the impact of the pandemic, which are used in the EU countries, are systematized. The types of direct (cash payments) and indirect (tax STA T E FI NA NC E Issue III (83), 2021 29 and credit preferences) financial support of business entities in Ukraine are described. Corrective elements are proposed in the mechanism of preferential lending to small and medium-sized businesses through increasing the loan amount by providing appropriate government guarantees to banks and covering credit risks by the state, provided that loans are invested in production, processing or innovation. The authors define a promising area of research as the development of anti-crisis measures to realize the innovative potential in the Ukrainian economy.
PATRONES DE FASEOLINAS Y ANÁLISIS RAPD EN ESPECIES DOMESTICADAS DE PHASEOLUS
Authors: Legaria-Solano Juan Porfirio
Published: May 2022

En este estudio se comparó la eficiencia de dos marcadores, uno bioquímico (proteínas faseolinas) y otro genético (RAPD, polimorfismos en el ADN amplificados al azar) para evaluar la diversidad genética y establecer relaciones filogenéticas entre P. vulgaris, P. lunatus y P. coccineus. El análisis de los patrones de faseolinas permitió detectar polimorfismo entre las especies evaluadas, pero no entre variedades de frijol o individuos de una variedad. Las especies más relacionadas, con base en el patrón de faseolinas, son P. coccineus y P. vulgaris, en comparación con P. lunatus. Los RAPD resultaron adecuados para la detección de polimorfismo entre variedades de P. vulgaris y entre individuos de P. coccineus. El polimorfismo entre cinco individuos de una variedad de P. coccineus fue de 24 %, y entre las ocho variedades de P. vulgaris fue de 27 %. Los RAPD también permitieron establecer relaciones entre individuos derivados de semillas con color diferente de testa en P. coccineus. Los frijoles negros fueron similares a los cafés y los pintos a los blancos, los morados fueron diferentes a los demás. Para P. vulgaris, un subgrupo se constituyó por frijoles tipo “Ojo de Cabra”, “Negro Americano”, “Pinto”, “Bayo”, “Garbancillo”, “Negro Bola” y “Peruano”, mientras que “Flor de Mayo” formó un subgrupo aparte. Los resultados concuerdan con la clasificación en razas de los frijoles de México establecida por otros autores. Según esta clasificación y las relaciones genéticas entre cultivares de frijol determinadas en el presente trabajo, “Negro Bola”, “Negro Americano” y “Peruano”, son variedades que están relacionadas con variedades de la raza Durango (“Ojo de Cabra”, “Pinto”, “Bayo” y “Garbancillo”), mientras que “Flor de Mayo” pertenece a la raza Jalisco.

En este estudio se abordan las ventajas biológicas y económicas que se generan con el establecimiento del sistema agroforestal “árboles en terrenos de cultivo” en Vicente Guerrero, Tlaxcala. Se determinó la estructura y composición de la vegetación y su rentabilidad financiera; para ello se colectó, identificó y muestreó la vegetación de nueve parcelas en tres zonas: terrazas con cultivo, bordos con cultivo más vegetación nativa y vegetación nativa, al emplear unidades de 10, 4 y 1 m2 para árboles, arbustos y herbáceas, respectivamente. Se registraron la composición botánica, densidad, diámetro normal, diámetro del dosel y altura de los individuos, para representar los perfiles de vegetación, estimar los valores de importancia y comparar las parcelas por medio de los índices de riqueza (Margalef) y diversidad (Simpson, Shannon-Wiener), así como a través de coeficientes de semejanza (Jaccard, Sørensen) y análisis estadístico multivariable (media aritmética no ponderada-UPGMA, componentes principales). En la evaluación financiera se utilizaron la relación beneficio costo (B/C) y el valor actual neto (VAN). De un total de 153 especies, colectadas, las familias mejor representadas fueron: Asteraceae, Poaceae y Fabaceae; el grupo funcional mejor representado fue el de las herbáceas con 119 especies. Cenchrus multiflorus Presl., Chloris submutica H.B.K. y Pennisetum clandestinum Hochst. ex Chioy fueron las herbáceas que tuvieron los mayores índices del valor de importancia; en el caso de los arbustos fueron para Agave salmiana Otto ex Salm-Dick y Haplopappus venetus (HBK.) Blake, así como Juniperus deppeana Steud. y Prunus persica (L.) Sieb. & Zucc. en los árboles. El índice de diversidad de Shannon-Wiener fue de 3.55 (parcela seis) a 3.89 (parcela uno) y la mayor afinidad florística se presentó en las parcelas ocho y nueve (81 a 89 %), tanto con los índices de semejanza como en el análisis multivariable. La relación B/C (2.3-7.1) y el VAN ($47,002.24-$176,761.65) establecen que el sistema agroforestal es rentable.

Published: May 2022

En este trabajo se evaluó la calidad pozolera de 21 colectas de maíz (Zea mays L) Cacahuacintle, representativas de la diversidad que existe en esta raza, en términos de tiempo de cocimiento para reventado (TCR), tanto en grano entero como despuntado, volumen de expansión del grano reventado (VE), porcentaje de granos reventados (PGR), y pérdida de sólidos y viscosidad en caldo de cocimiento. También se evaluaron los caracteres morfológicos y físicos de mazorca y grano, así como algunos caracteres anatómicos del grano. Las formas dominantes de mazorca entre las colectas fueron cónicas y cilíndricas. En el grano se identificaron cuatro formas básicas que fueron: redondeada, redondeada globosa, triangulada apastillada y alargada apastillada. Hubo una relación entre la forma del grano y el TCR, ya que los granos de forma redondeada globosa presentaron los menores TCR. El despunte del grano redujo de manera importante el TCR y mejoró tanto el VE como el PGR. La viscosidad y pérdida de sólidos en el caldo de cocimiento de los granos enteros mostraron una correlación positiva, comportamiento que no se observó en el grano despuntado.

Published: May 2022

La vida de anaquel de nopal verdura (Opuntia ficus-indica) mínimamente procesado es de 1 a 2 d a temperatura ambiente y de 7 d a 5 °C. Los principales problemas que limitan esta vida de anaquel son el oscurecimiento y la secreción de mucílago. En este trabajo se evaluó el efecto de la adición de ácido ascórbico solo o con ácido cítrico en la reducción del oscurecimiento y calidad del nopal verdura mínimamente procesado y envasado en bolsas de polietileno durante el almacenamiento a 5 ° y 10 °C. El material vegetal usado consistió de cladodios tiernos de apariencia fresca que se seleccionaron, se lavaron con agua clorada, se desespinaron y se cortaron en cuadros. Se formaron cuatro fracciones que se asignaron a tratamientos con ácido ascórbico (AA), ácido cítrico (AC), una mezcla de AA y AC, y agua clorada como testigo; todas estas soluciones contenían sorbato de potasio. El producto de cada fracción se envasó en bolsas de polietileno, con 250 g cada una; y se almacenaron por 21 d a 5 °C y por 14 d a 10 °C. Con base en la evaluación de la composición de la atmósfera (O2 y CO2) dentro del envase, apariencia (oscurecimiento y secreción de mucílago), firmeza, color y calidad microbiológica (cuenta total de mesófilos aerobios, coliformes totales y fecales, hongos y levaduras), se concluyó que no es recomendable utilizar ácido cítrico como inhibidor del oscurecimiento. No obstante, con la aplicación de ácido ascórbico es factible extender la vida de anaquel de nopal verdura mínimamente procesado a 11 d a 10 °C y 20 d a 5 °C con una calidad microbiológica aceptable, de acuerdo con la Norma Oficial Mexicana NOM-093-SSA1-1994.

Published: May 2022

Las piretrinas extraídas del piretro son insecticidas vegetales eficaces contra plagas, y son menos riesgosas para el hombre y ambiente que los insecticidas sintetizados químicamente. Por el potencial económico del cultivo, originario de Irán y Yugoslavia, se realizó esta investigación con la finalidad de cuantificar en México el rendimiento de inflorescencias y tallos florales (escapos) de piretro (Tanacetum coccineum (Willd.) Grierson), así como analizar la variabilidad fenotípica entre plantas. La siembra se hizo en almácigo y las plantas obtenidas se trasplantaron a la intemperie, en Montecillo, Estado de México. Dos años después del trasplante, 84 % de las plantas produjeron tallos con inflorescencia y 16 % sólo follaje. El número promedio de tallos por planta fue de 15, con un valor máximo de 84. El rendimiento obtenido fue de 400 kg ha-1 año-1 de inflorescencias secas y 948 kg ha-año-1 de tallos secos. Se observó alta variabilidad en color de inflorescencias (en rango de blanco a rosa y rojo), número de inflorescencias por planta (C V = 88 %), peso de inflorescencias (C V = 28 %), diámetro de inflorescencias (C V = 15 %), número de tallos por planta (C V = 88 %), peso de tallos (C V = 37 %) y longitud de tallos (C V = 30 %). No se detectó correlación entre número y peso de inflorescencias por planta (r = -0.03), ni entre número y peso de tallos por planta (r = 0.01). Se concluye que el cultivo comercial de piretro es posible en México.

Published: May 2022

The constant growth of the population makes the commitment of means of transportation more than necessary. The objective of this research is to analyze the impact of road networks on the development of the Copargo municipality. To carry out this research, the methodology adopted consisted firstly in designing survey forms, then in carrying out documentary research, and in conducting field surveys with 176 people using questionnaires and interview guides. The collected data were processed using software such as: Excel spreadsheet and ArcView 3.2 and the results were finally analyzed. The results of the research showed that the trails are the most used by the populations to access socio-economic services. They are more numerous (95%) followed by paved roads (5%) represented by RNIE3. It should be noted that the existing infrastructure is not only insufficient but also suffers from poor and regular maintenance. 75% of this infrastructure is in poor condition. 55% of the users surveyed are located near the roads to carry out socio-economic activities. So, to ensure the socio-economic development of the commune, it is necessary to subdivide all the districts, provide them with quality roads and ensure their regular maintenance.

Published: May 2022

The wood resources of classified forests are nowadays subject to accelerated degradation. This research aims to characterize plant groups and their use by anthropogenic activities in the Ouémé-Boukou classified forest (FCOB). The field surveys were carried out among 81 people through a reasoned sampling according to the economic activities having an impact on the study forest. Following the sigmatist method of Braun Blanquet (1932), the floristic inventory was carried out in 31 circular squares of 18 meters radius installed according to the criterion of homogeneity of the vegetation and the topography of the environment. The collected data was submitted to the CAP (Community Analysis Package) software for the realization of the dendrogram. Thus, 27 woody species divided into 14 families and 23 genera have been inventoried and are classified in 3 plant groups. The most dominant families are Combretaceae (35%), Cesalpiniaceae (29.54%), Sapotaceae (20.17%), Papilionaceae (11.11%) and Mimosaceae (6.33%). The most represented life forms are Mesophanophytes (46.27%) and Microphanerophytes (38.53%). In terms of chorological realities, Guineo-Congolese species (43.57%) and Sudanese species are more represented (49.73%). In addition, agriculture, aerial grazing, wildfires, coal production and population growth are among the determining factors in the degradation of the study area. The flora of the study area gives a slight hope by its multiple regenerations despite anthropogenic pressure.

Published: May 2022

The extractivism is an economic growth model based on the exploitation of primary natural resources, little transformed, including oil, to be sold on the world market. Several countries, including Mexico, were inserted into an extractivist model, to obtain the highest possible income, through which their industrialization and development were financed; on the other hand, these resources have also been used to pay for growing public spending. The objective of this research work is to determine the impact of oil extractivism on the economic growth of Mexico. For which an econometric model was developed, by ordinary least squares, analyzing the period of time 1990-2020. The results obtained show negative effects associated with a high dependence on public finances toward oil extractivism, in addition, derived from the lack of transformation and improvements of the Mexican extractivism model, negative impacts are generated in the economy that, if not addressed, can trigger a domino effect with greater losses for the oil sector, which could lead to increasing the country risk, an aggravating the economic and social situation of the country in the medium term.

Authors: ÁLVAREZ-CISTERNAS Marisol del Carmen
Published: May 2022

This academic article addresses the issue of university governance in the 21st century, and the need for ethical leaders in the management of higher education institutions. In this way, some primitive, perfectible and situated guidelines are proposed, which allow progress towards reflection and formalization, of qualities and attributes that management leaders must have, attending to the demands and interpellations that society as a whole makes to The universities, it is not enough that who directs the institutions and the management team that accompanies them, have extraordinary highly qualified professional competences, but they must also have specific competences that allow them to address issues associated with ethics in the institutions they govern. In this way, from a descriptive qualitative methodological approach based on documentary analysis and empirical approaches to successful models, it is revealed what is an ethical leadership, its qualities and attributes, as well as some strength ideas of how a managerial leader can move towards an ethical leadership in its management. As a result, the article proposes some guidelines referring to sensitivities, principles, values, and personal dispositions, which allow the leader to face and live ethical conflicts, even when his own values are put into play.

Published: May 2022

As one of the most hotly debated topics of the twenty-first century, ‘Gene Therapy’ holds the promise of a solution for
most diseases,the controversy surrounding the alteration of human imperfection,and the possibility of a sort of medical
care that most of us would never consider conceivable. Pharmaceuticals aren't always able to treat human disorders. So,
meddling with a person's genes, the blueprints for how biological systems are constructed and operate, is the only way
to fix the majority of diseases. The gene-editing method is being used by some researchers to accurately alter DNA
sequences. Others are changing immune cells genetically to give them the ability to fight diseases. And, in the last few
years, the development of a wide spectrum of therapies in which disease-causing genes are completely changed has
accelerated dramatically. Gene therapy is defined as the treatment of disease by the transfer of genetic material into
cells. This review will look at gene transfer technologies as well as present and potential applications, with a focus on
future development and design.
Link-Layer Retransmission-based Error-Control Protocols in FSO Communications: A Survey
Authors: Le Hoang
Published: May 2022

 Free space optical (FSO) communication has established a reputation for itself capable of delivering high-speed data services over long distances without exhausting radio frequency (RF) resources.

FSO communication can be considered in different network scenarios, including inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, and terrestrial links. It is expected to be one of the key enabling technologies for the next generation of 6G wireless networks. Nevertheless, despite the great potential of FSO communications, its performance suffers from various limitations and challenges: atmospheric turbulence, clouds, weather conditions, and pointing misalignment. The error-control solutions, including physical layer (PHY) and link-layer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on error-control solutions in FSO systems primarily focussed on the PHY methods, we instead provide a review of link-layer solutions. In particular, we conduct an extensive literature survey of state-of-the-art retransmission protocols, both automatic repeat request (ARQ) and hybrid ARQ (HARQ), for various FSO communication scenarios, including point-to-point terrestrial, cooperative, multi-hop relaying, hybrid FSO/RF, satellite/aerial, and deep-space systems. Furthermore, we provide a survey of recent literature and insightful discussion on the cross-layer design frameworks related to link-layer retransmission protocols in FSO communication networks. Finally, the lessons learned, design guidelines, related open issues, and future research directions are exposed.
Gate-Stack Engineered IGZO-based Multi-bit OTP FeTFT with Lifelong Retention for Inference Engine Applications
Authors: De Sourav
Published: May 2022

This paper reports back-end-of-line (BEoL) compatible indium gallium zinc oxide (IGZO) based multibit one-time programmable (OTP) ferroelectric thin-film transistors (FeTFT) with lifelong retention capability. The maximum temperature of the entire fabrication process was limited to 350oC. The gate-stack engineering by varying the thickness ratio of hafnium zirconium oxide (HZO) and IGZO layer fomented data-retention capability over ten years and OTP property. Further, we have evaluated the performance of IGZO-based OTP FeTFT as synaptic devices for an inference engine. The system-level simulation revealed inference accuracy loss of only 1.5% after ten years without re-training for Modified National Institute of Standards and Technology (MNIST) hand-written digits in a multi-layer perceptron (MLP) neural network with a baseline of 97%. The proposed inference engine also showed superior energy efficiency and cell area of 95.33 TOPS/W (binary) and 8F2, respectively.

Design and testing of a composite pressure hull for deep autonomous underwater vehicles.
Authors: Elkolali Moustafa , alcocer alex
Published: May 2022

 This paper outlines the design and testing process of the hull of a deep small Autonomous Underwater Vehicle (AUV), rated at 2000m depth. Many existing AUV pressure housings use aluminum or other isotropic traditional metals, instead of composites due to the complexities of the design of composites at such big load. The research at hand explains the process of design starting from setting the geometrical constraints for the design to mass production. To the best of the authors’ knowledge, none of the previous studies has presented such detailed description of the work. Carbon fiber reinforced epoxy material was chosen thanks to its high strength-to-weight ratio and similarity of its compressibility to sea water. Material characterization was performed to obtain the material properties under loading conditions using a modified method of the Combined Loading Compression testing technique. A specific fixture was designed and manufactured to test filament-wound tubes. An analytical model was developed using MATLAB, a finite element model was created using ABAQUS, and the results of the two models were compared. A set of recommendations was introduced for the stacking sequence to provide the lowest possible stresses, regardless on the diving depth of the vehicle. Afterwards, a quality control set of tests was conducted, including seawater absorption under high pressure and void analysis using destructive and non-destructive tests. Pilot samples were manufactured and tested in a pressure vessel, where it was cycle-tested and inspected using visual and ultrasonic testing. Other samples were fail-tested and showed a failure at ∼93% of the expected failure load. Such range can be considered good to provide safe operation for the vehicle at the designated depth, given that the factor of safety included covers more than 7% of the failure load. The proposed design methodology has shown that CFRE can be safely used even at such high depths. 
A Detailed Analysis of the Impact of Increasing Inverter-Based Resources on the Oscillatory Behavior of the Western Interconnection

Published: May 2022

The retirement of conventional synchronous generators and the integration of inverter-based renewable energy sources (RESs) are transforming power systems in unprecedented ways. Understanding the impact and consequences of this resource mix transition is crucial to maintaining reliable grid operations. Aiming at this, the paper examines the impact of increasing RESs on the oscillatory behavior of the U.S. Western Interconnection (WI). Two approaches were used in the paper for performing this assessment: measurement- and model-based. In the measurement-based approach, quantile-regression-based correlation analysis was performed using historical data collected from the WI to analyze the impact of increasing RES penetration levels on system modes. In the model-based approach, the 2018 heavy summer operating WI model was used as a base-case to create several use-cases by replacing synchronous machine models with RES machine models in different proportions to analyze the impact of increasing RES penetration levels on the system modes. In this analysis, four scenarios were considered that included system-wide and area-specific increases in RES penetration levels. In the model-based approach, a detailed eigenvalue analysis was also performed to understand the trends observed in the damping ratio of system modes. Our detailed analysis concludes that the increasing RES penetration levels can have a significant impact on system modes. However, no single trend could be identified to correlate the impact of the increasing RES penetration levels on system modes. According to our model-based analysis, this impact was, in fact, dependent on the group of synchronous generators that were replaced by the RES machine models; for instance, replacing synchronous generators in Alberta, that have high participation factors and significantly contribute to the damping of the NS-A mode, had the most impact on the NS-A mode, while the impact on the NS-A mode was little when synchronous generators were replaced in the rest of the WI. Based on this analysis, the authors conclude that the impact of the increasing RES penetration level on a system mode is dependent on the overall dynamics of the evolving system and the damping contribution to that mode by the generators having high participation factors in that mode.

Pyeloureteral duplication is a duplication of the excretory system of a renal unit. Renal duplication is a congenital anomaly, estimated in the general population at 1/125. Familial forms have been described and estimated at 1 in 8 in the siblings. Upper urinary tract malformations are not uncommon in adults and can lead to destruction of the renal parenchyma if diagnosis and management are delayed. Recurrent back pain is the most common symptom. It may also be due to infectious complications of the upper pyelo in stasis or due to ectopy. Urinary lithiasis is found in 26% of cases according to some series. Endoscopic incision in the context of ureteral duplicity, completed by ureteroscopy with drainage of the Upper excretory tract, may be the treatment of choice in adults. Simple, minimally invasive and with low morbidity, it allows an efficient drainage.

Femoral shaft fractures are common orthopaedic problems with interesting treatment evolution based on evolving clinical evidence. Though closed reduction and locked intramedullary nailing is the gold standard in adults, this requisite tools and skills for this option may be unavailable in some low income countries necessitating other treatment options. We retrospectively review the presentation pattern and treatment outcomes of 71 femoral shaft fractures in a tertiary center. Records of these patients who meet the inclusion criteria were recruited into the study. Relevant data was extracted for the patients’ folders and supplemented with calls to the patients where needed information was unavailable. Data was presented in frequency table and charts. Femoral shaft fractures represents 7.6% of the total number of patients with musculo-skeletal conditions seen at the studycentre within the study period with a male preponderance. Open reduction and locked Intramedullary nailing and hip Spica cast were was the treatment of choice in adults (62%,n=44/71) and children respectively (11.3%, n=8/71). Bone union rate at 12 weeks post intervention was (57.7%). This increased to 90.1% by the end of the eighteenth post-operative week. The most common complication was wound infection in open fractures (4.2%, n=3/71).

Introduction: Clavicle fractures are common, and account for about 2.6 % of all fractures and nearly 44 % of those in the shoulder girdle. Fractures of the middle third of the clavicle are most common (81%). Surgical operation for displaced clavicle fractures is controversial. Traditionally, these fractures have been treated in non-operative ways. This traditional treatment is not without complications, such as shortening, nonunion, deformity and unsatisfactory patient outcomes. In recent days, operative treatment has proven superior results. Aim of the study: Early union & reliable treatment with predictable outcomes. Methods: This is a prospective study, a total of 15 patients were included and analyzed in this study. This study was carried out from January 2016 to June 2020 at Z. H. Sikder Women’s Medical College Hospital & Northern International Medical College and Hospital. The method of fixation of the clavicular fracture was open reduction and internal fixation with a reconstruction plate in twenty patients, a hook plate and T-plate for distal clavicle fracture.

The value of African traditional education in the impartation of critical skills, competences and values needed for development in the continent cannot be overlooked. Yet, in most cases, the traditional forms of education have not been properly integrated into modern education systems in Africa that are based on western or Euro-American conceptualisations of education. For this reason, important cultural values, such as those of the Bukusu community of western Kenya, are fast going into oblivion. The search for a holistic education cannot be realised without giving regard to education in the traditional African communities. The study therefore sought to establish the influence of youth education on content knowledge of teachers in the Bukusu community of Western Kenya. The research tools were interviews and participant observation. The target population was ninety-eight (98), consisting of twenty-four Bukusu Council of elders, five Bukusu community traditional educators, twenty-four leaders of culture council of Bukusu elders, and forty-five Bukusu community traditional circumcisers. Respondents were selected by purposive sampling and snowballing sampling procedures. The sample size was seventy two (72) respondents consisting of twenty Bukusu council of elders, twenty-one leaders of culture council of Bukusu elders, two Bukusu community traditional educators, and twenty-nine Bukusu community traditional circumcisers. Quantitative data was analysed with the help of the Statistical Package for Social Sciences (SPSS) computer program while qualitative data was analysed thematically. Results of data analysis were presented in the form of tables, frequency counts and percentages. The findings of the study showed that most participants who had acquired adequate knowledge in youth education had been exposed to adequate knowledge in Bukusu culture. This implied that youth education is the most critical stage in Bukusu culture. The study recommends for a compulsory .........
