Authors: - Prafull A. Kose , - Abhijit R. Aney
Published: February 2023

The purpose of this paper is to provide instructional material on purpose, approaches, and strategies and some essential techniques of utilizing English Novels in a language classroom. As far as the rationale for focusing on novels for teaching purposes is concerned, Chen (2006) has explained that regardless of culture or background, while communicating, be it explaining a thought or making an argument, and the narrative is one of the two modes of thinking. Also, because of the engaging and true to life nature of characters/relationships/events, long fiction is emotionally evocative and very effective in teaching language. A novel study allows those students to develop their reading comprehension and thinking skills through high-quality literature. It lets them practice and refine their skills related to the standards in a much more engaging format than the typical reading textbook. A novel study is an opportunity to build a love of reading.

With  the  growing modern  civilization, the  ever  increasing role  of plants to  human  life has  placed  before  us  many  fold tasks  for  understanding intimately the  world  of the  plants  and their relationships with  human  being.Demographic analysis of  a plant  community is the  first and foremost basis  for  study of any  piece  of  vegetation. The floristic studies based  on  demography data  present a complete picture of the  vegetation i.  e. distribution-pattern and seasonal  changes  of  the   plant   communities  inhabiting a  particular  area   or  region.   The  dependence  of  man  on medicinal  plants  is next to food  for  life sustenance. Continuous exploitation of  medicinal plants has  also  been  causing extinction of certain  species.  There  is, therefore, need  for  intensive agricultural studies leading  to  genetic improvement and cultivation methods for  expansion of area under  medicinal  and  aromatic plants.In the  present investigation a fact was  established by long  observations that the  vegetation of  a region  or a locality,  in general,  follows a certain  well-defined distribution pattern.  Authors have  studied the  vegetation of Mainpuri  district of Uttar  Pradesh. This area  is located  in tropical zone  between 26°53'  to  2734' North  latitude  and  7827' to 7926' East longitude  and covers an  area  of nearly  4343  s. km. The  climate  of the  district is  markedly  periodic and  of semi-arid nature  which  is characterized by  a dry  and  hot  summer,  a warm monsoon and  a bracing cold  winter.  The  soil  of the district is divisible  into three  types  i.e. Matiyar,  Bhur and Dumat within this  there is a vast  area of wasteland known as 'usar' is available,  which  is not fit for  irrigation. Here 66752 hectares of land is usar land therefore the  vegetation of this land  is  scarce and  only  few  restricted plants  flourish,  therefore,  understanding of  natural ecosystem is  important for their conservation. During  the  present ecological investigations it was  found  that  the  medicinal herbs  viz:  Adhatoda  vasica,  Achyrantes aspera,  Argemone mexicana. Bacopa monnierri,   Centella  asiatica, Datura  stramonium, Calotropis procera, Euphorbia hirta,  Plantago ovata,  Solanum xanthocarpum, Trianthema portulacastrum,  Tribulus  terrestris,  Withania  somnifera were   abundant.  Medicinal grasses viz.  Cynodon dactylon,  Cymbopogon nardus showed  the  dynamics regeneration process by suckers  and  rhizomes  and  medicinal trees  like  Acacia nilotica, Pongamia pinnata, Syzygium  cuminii, Terminalia arjuna,  Ficus bonghalensis, were  most  popular.

Utility of dimethylsulfoxide to preserve synovial fluid samples for microcrystal detection and identification
Authors: Pérez-Ruiz Fernando , Lopez-Bardón Elsa , Lioté Frédéric , Schlesinger Naomi , Uhlig Till , Mateos-Mazón Juan J.
Published: February 2023

Aims: To study whether the addition of dimethylsulfoxide (DMSO) to synovial fluid (SF) samples could be helpful to store frozen samples to improve the rates of detection and identification of crystals.
Methods: Cross-sectional study of samples of SF consecutively obtained. Three aliquots were generated: one for immediate observation by a senior observer, and 2 to be frozen, one with 10% DMSO (DMSO+) and one without DMSO (DMSO–). Each aliquot was randomly allocated and blinded for further observation when once the samples were unfrozen 3 months afterward. Variables included for analysis were total leucocyte count,
detection of crystals, identification of present crystals as monosodium urate (MSU) or calcium pyrophosphate (CPP), number of fields to the first crystal observation, and number of crystals per field. The vitality of leucocytes was evaluated using a trypan blue stain. All samples were examined using ordinary light and polarized light with a red compensator, and unfrozen samples by both senior and junior observers.
Results: In the 30 reference samples of SF studied, the mean leucocyte count was 13.1 × 109/L, and 18/30 samples showed crystals (8 MSU, 10 CPP). Once unfrozen, leucocyte counts were 58% lower in DMSO aliquots vs. 22% in DMSO+ aliquots, with vitality (> 50% cells) reduced from 100% in the reference sample to 76.6% in the DMSO+ aliquots to none in the DMSO– aliquots. Agreement in the detection of crystals was much better
in DMSO+ aliquots than DMSO– (kappa 1.00 vs. 0.69 and 0.65 vs. 0.11 for the senior and junior observers respectively). Moreover, 4/5 false-negative crystal detection in DMSO– aliquots showed CPP in the reference simple, even though a high density of crystals was observed in the reference sample.
Conclusions: The addition of 10% DMSO to SF samples allows freezing and storage with a small loss of leucocyte counts and excellent agreement in the detection and identification of crystals. Cellular lysis may account for the false negative results in aliquots without DMSO, especially in the case of CPP, non-refringent crystals.

Published: February 2023

The abundance of drinking water is necessary for daily needs, but recently it has become a worrying obsession worldwide, as it requires the use of fossil fuels for its production, and since the whole world is moving to reduce greenhouse gases emissions, it was necessary to think about using alternative renewable energy in the production of drinking water and that was through desalination of salty water. Solar energy has been widely used. The methods that use solar power are divided into direct and indirect, which include several steps, and the solar energy systems used are varied. In the present study, desalination methods and some types of solar energy systems used are mentioned with a comparison of the amount of production and costs, in addition to the improvement resulting from the use of PCM. It was found that the solar Fresnel lens system is the most effective in producing fresh water compared with its cost. The solar desalination stations in Jordan are 29 and only 1 solar-powered desalination plant out of them, but the universities and independent factories have their solar deamination systems.

SYSTEM CHARACTERISTICS OF MARKETING AND ITS IMPACT ON THE ACTIVITIES OF INTERNATIONAL COMPANIES
Authors: Kolisnyk Vladyslav , Zharova L.
Published: February 2023

The paper focused on marketing influence of international economic relations. Te based on the assumption that in the context of the modern development of a market economy and entrepreneurship, the issue of studying marketing activities at an enterprise is becoming increasingly relevant. This is primarily due to the high growth rates of entrepreneurship in the country's economy. Most are small enterprises or the sphere of small business as it is also called. The simplicity explains this in organizing their small business, and their greater adaptability to the changing market conditions. They respond faster to market needs, and can therefore adapt more quickly. However, it is in the sphere of small business that a very high degree of competition is observed, and in order to survive in the market and make a profit, enterprises need to position themselves. This is necessary precisely so that consumers, among a wide variety of identical products, choose what we produce. And here, of course, a competent marketing policy is the main tool and assistant.

The productive use of the marketing approach in the production, business, marketing and commercial activities of an enterprise depends, first of all, on how flexible and quick it is to respond to all changes occurring in the market and respond to new consumer needs through the development of new products and technologies; its consumer demand; from creating an appropriate economic and legal environment that would ensure real economic independence of the enterprise in all respects in the market.

We grounded that the better the marketing mix is developed at the enterprise, the more efficient its activities will be. With the help of marketing activities, there is a constant search for new markets, consumers, new types of products and services that contribute to ensure the company the highest level of profit. The marketing mix acts as a tool for regulating production and marketing.

Published: February 2023

The main objective of this paper is to study how firm-specific factors affect the financial performance of tourism-related young small and micro-sized firms located in Algarve, Portugal, that started their activity during the last years of the debt crisis of Europe. The sample included 106 Portuguese small and micro-sized firms in the hospitality sector, established between 2012-2014, which remain active in 2019 and financial data from 2015 to 2018 was analysed. Descriptive statistics, group statistics, correlations, and regression model analyses were applied. The dependent variable representing profitability was the return on assets ratio (ROA). The independent variables were short-term, long-term and total debts, slack resources, sales growth, tangibility and size of the firm. A negative relationship between performance and long-term and short-term debts was found, confirming the theory that the most profitable firms tend to borrow less as they do not need external capital. Also, a negative relationship between ROA and tangibility was found, which means that as the level of tangible assets lessens, more intangible assets there are. These results give some hints to help tourism-related small and micro-sized firms located in Algarve take innovation, flexibility, and digitalisation strategies, particularly important during a pandemic crisis.

Published: February 2023

The Council of Europe is one of the oldest European institutions in operation. This paper aims to examine the impact of economic growth and terrorism on international tourism for 33 Council of Europe countries. The period considered for analysis encompasses data from 1995 to 2018. The Panel Autoregressive Distributed Lag method was selected to gauge the short- and long-term impacts. The effects of globalization and the real effective exchange rate were also considered. The presence of sectional dependence heteroscedasticity and first-order autocorrelation in the models inferred the use of the Driscoll & Kraay (1998) estimator. The results found here support that Council of Europe decision-makers should develop public measures that promote tourism activities. At the same time, they can propose measures aimed at increasingly reducing terrorism and develop measures to encourage the attraction and capture of international tourism through the intrinsic advantages of the globalization phenomenon.

Published: February 2023

The COVID-19 pandemic has brought many fundamental changes. Especially in the tourism sector, where people are in constant communication and interaction, negative effects have been seen excessively. This situation also affected tourism employees economically, psychologically and physically. Therefore, paper is aimed to reveal the relationship among resilience, perceived vulnerability and mental health perceptions within the scope of hotel employees. This study examines the effects of psychological and employee resilience on hotel employees’ mental health perceptions. In this context, “psychological resilience has a signifant positive influence on hotel employees’ mental health perceptions” and “employee resilience has a significant positive influence on hotel employees’ mental health perceptions” have been developed. The study also examines the mediating the role of perceived vulnerability in the effect of individual-level resilience on hotel employees’ mental health perceptions. In this context, “perceived vulnerability mediates the effect of individual-level resilience on mental health perceptions” has been developed. In total, 391 questionnaire forms were analyzed using a structural equations model to test the hypotheses. The results show that hotel employees’ psychological and employee resilience make their mental health perceptions more positive. Perceived vulnerability partially mediates the effect of individual-level resilience on mental health perceptions.
Civil law consequences of object construction on a land provided for construction (superficies)
Authors: Ilkiv Oleh
Published: February 2023

The article is devoted to the analysis of civil consequences of superfidence as a legal category of the Institute of Rights in Ukraine.

The right to build a foreign land should be considered as a legally secured opportunity and ability of a person to carry out all kinds of urban planning activities on a land plot or acquired for such purposes. For construction, the person must have an appropriate legal title (superficies agreement) on the basis of which state registration and determine the boundaries of the area in nature in the terrain. Superficies rights to the land should be recorded in licensing documents for construction or declarations on the start of construction.

Investigated that a new superficies acquirer and the owner of the land have the same rights and responsibilities that were provided for by the conditions of the previous supervisory superfiction. In this case, there is a succession of rights and obligations for a new superfidence, which accounted for the content of the previous agreement between the owner and the user (superficies). It has been found that the transmission of a land that is the subject of a superficies agreement between the owner and the user on the basis of a new agreement to another person should be carried out with the consent of the owner.

Transfer without the consent of the owner of the land, which is subject to a superficial agreement to another person contradicts the basic principles of ownership, regarding the disposal of the object of real rights.

A disadvantage is the fact that in the norms governing the legal consequences of termination of the right to use the land are not regulated by their onset in case of failure to reach an agreement between them, giving a solution to this issue to solve the court taking into account the circumstances of the case.

During the study by the author, it is proposed to complement the norms of civil law on the transition of the right to use a land for construction from the Superficielity, after the start of construction, it is possible to provide permits to the acquirer for the construction of the relevant construction object.

Key words: superficies, ownership, real rights, land, building object.

Published: February 2023

The medical field is quite complex and has a high level of conflict, so there are often problems with the peculiarities of the end of life. Thus, the article analyzes the possible options for ending life, taking into account the will of both the immediate person and his relatives. Based on the analysis of the case law of the European Court of Human Rights, the problematic issues related to the ways of ending the lives of individuals are outlined. The definition of «euthanasia» is also given and the appropriate classification is given, the criteria of which are the direct participation and consent of the person in respect of whom they intend to carry out the above procedure. It is established that the «right to life» cannot be interpreted in a negative aspect, the state has a positive obligation to protect human life and health, and this right cannot be interpreted as a death permit. In addition, the issue of stopping treatment that supports vital functions of the body is revealed. It is determined that the use of passive euthanasia is possible in cases provided by law. The factors and criteria that states should be guided by when using passive euthanasia are analyzed. In addition, it is established that the state has an obligation not only to refrain from harming individuals, but also to take all urgent and possible measures to protect persons and provide them with appropriate treatment. The purpose of the article is to get acquainted with the concept, types and methods of euthanasia. The basic decisions of the ECHR in the context of this issue are indicated, and a description of the latter is given. Summing up the study, it should be noted that the problem of interruption of life remains unified. The ECHR stated that the State had no negative obligations in the context of Article 2 of the ECHR and therefore had no right to die. The ECHR, in turn, gives wide discretion to states and only undertakes to monitor the legality of passive euthanasia, which in turn can be enshrined in the law of the country concerned. States, refraining from the introduction of active euthanasia, should take all possible measures to maintain and protect persons and provide them with the necessary treatment.

Key words: European Court of Human Rights, European Convention for the Protection of Human Rights and Fundamental Freedoms, euthanasia, the right to life, the right to adequate and necessary medical services.
Practical implementation of interventional doctrines against illegal trafficking
Authors:   Borys Kindiuk, Mykola Kotsur
Published: February 2023

The article is devoted to the analysis of the problem of application of interventionist doctrines of legal responsibility for illicit drug trafficking. It is noted that the interventionist doctrine is a prerequisite for the creation of legal norms, and is also a source of law that affects the content of regulations.

There are three doctrines of responsibility used in the field of drug trafficking: interventionist, eclectic, liberal.

The main stages of anti-drug legislation are considered and three periods of use of interventionist doctrines are identified: 1) time interval from X to early eighteenth century; 2) the first years of Soviet power in 1917—1921; 3) the stage from 1974 to 1989. The most characteristic features of the interventionist doctrine in the field of responsibility for illicit drug trafficking are singled out: 1) wide use of the norms of the criminal legislation; 2) application of severe penalties; 3) the priority of public interests to the detriment of the interests of the individual. It is stated that in practice, on the basis of such doctrines, legislative acts were adopted, in which the penalties were the death penalty, long terms of imprisonment, confiscation of property. Thus, after the end of the fighting of 1917—1921, a significant number of drug addicts appeared in the country, among former Red Army soldiers who committed crimes in order to obtain money to purchase such substances.

It is shown that the use of interventionist doctrine has not led to a decrease in the number of drug addicts, the number of crimes related to these dangerous substances. These results indicate the need to amend the articles of the Criminal Code of Ukraine, which set long terms of punishment.

Key words: Criminal Code, Ukraine, legal liability, interventionist doctrine, drug trafficking, punishment.

One of the key factors in the country’s GDP growth is reproducible capital, which lays the foundation for the production of products, works and services. Accordingly, the study of the state, structure and dynamics of the dominant component, fixed assets, is one of the priority tasks of statistics and econometrics. This implies the purpose of the study, which is to assess the predictive capabilities of econometric models. To achieve this goal, a pool of mathematical-statistical and econometric methods was used, in particular tabular and graphic, descriptive statistics, correlation-regression, adaptive modeling. The main results include: analysis of the structure of investments did not find new or hidden patterns, so investments are directed to the modernization or renewal of capital-intensive areas – these are buildings, structures and land (about 40% of the total investment), the main industries are industry and transport; visual analysis of the dynamics of the temporary series of investments in fixed assets showed the presence of a long-term, seasonal and situational component; the construction of 6 econometric models reflecting the complex dynamics of the macro indicator in question made it possible to distinguish two adaptive models belonging to the group; thus, the best forecast opportunities for complex dynamics of investments in Russian fixed assets are observed in the three-parameter exponential smoothing model and SARIMA (1,0,0)(1,1,0) [4]. The results obtained in the course of the study will be useful for scientists involved in modeling and predicting complex-structured time series

Published: February 2023

n the last decade, there has been an active digitalization of industrial production based on rapidly developing information technologies, including artificial intelligence technologies. This is largely due to the development of deep learning methods and their applications in computer vision. Since the mid 2010s convolutional neural networks demonstrate exceptional efficiency in solving problems such as the detection, classification and segmentation of various objects. As a result, computer vision methods are beginning to be actively used in the problems of quality control of raw materials and finished products. All this applies to the mining industry. However, in the Russian scientific literature there are practically no systematic reviews of computer vision applications in this area. The present study aims to fill this gap. The paper provides a systematic review of the history of development and the current state of the methods and technologies of machine vision used in the mining industry for the analysis of solid materials, demonstrates the latest achievements in this area and examples of their application in the mining industry. The authors have analyzed 29 research papers in the field of application of computer vision in the mining industry and classified the stages of technology development from the mid-1980s, when computer vision was used without the use of machine learning, and ending with modern research based on the use of deep convolutional neural networks for solving problems of classification and segmentation. The effectiveness of the methods used is compared, their advantages and disadvantages are discussed, and forecasts are made for the development of computer vision methods in the mining industry in the near future. Examples are given showing that the use of convolutional neural networks made it possible to move to a qualitatively higher level of quality in solving problems of classification and segmentation as applied to the analysis of output volume, particle size distribution, including flakiness, angularity and roughness, dust and clay content, bulk density and emptiness, etc.

Currently, a new type of information security threat is spreading – hidden mining, which uses the computing resources of users through browsers. Malicious software based on WebAssembly files unauthorizedly uses the computing resources of users of computer systems. The existing methods for detecting “hidden miners” in the browser environment are based on: dynamic analysis algorithms, however, they have a number of limitations, for example, it is required that malicious software for hidden mining work for a certain period of time, they are characterized by a large number of false positives; algorithms of browser extensions that use blacklists to prevent unauthorized access to the user’s browser environment, however, attackers often change their domain names, etc. The relevance of using special protection tools against browser-based cryptominers is beyond doubt. The purpose of this study is to increase the level of security of the browser environment of users of computer systems. Achieving this goal is possible by solving the main task - the timely automated detection of “hidden miners” in the browser environment and the prevention of unauthorized mining. The article describes software that does not depend on the browser or operating system used, is resistant to attempts to circumvent protection by intruders, will allow users to reliably recognize “hidden miners”, and increase the level of information security of a computer system. The software is based on classification algorithms implemented on the basis of a convolutional neural network. The results of the study and experimental data showed that as a result of testing the software, the recognition accuracy of “hidden miners” in the browser environment is 91.37%.

Por este motivo surge este trabajo científico que tiene como objetivo analizar el liderazgo docente como apoyo socioemocional en el aula. Por esta razón se desarrolló la investigación bibliográfica y exploratoria, con enfoque cuali-cuantitativo o mixto. Para la obtención de los resultados se aplicaron los métodos de análisis-síntesis, deductivo y estadístico. Además, se aplicó una encuesta semiestructurada con respuesta de selección múltiple a las unidades de análisis de la investigación, se empleó un muestreo al azar simple, donde se seleccionó de forma no aleatoria a 23 docentes de algunas instituciones educativas del cantón Chone. A partir de los resultados obtenidos se concluyó que para lograr un liderazgo docente eficiente y eficaz se debe trabajar en desarrollar de manera adecuada la parte emocional en el aula, ya que éste es una parte fundamental para mejorar los procesos en el contexto educativo.

El presente artículo tiene como objetivo analizar el surgimiento del Acuerdo Ministerial MDT-2020-223, expedido como una alternativa de oportunidad laboral en época de pandemia a fin de generar nuevas fuentes de trabajo. Al haberse expedido como alternativa, es necesario conocer inicialmente, el significado y alcance de un contrato laboral conjuntamente con sus características y así conocer a quién beneficia este contrato, si a la parte empleadora o a la parte trabajadora. Por lo que se investigarán las características de esta modalidad contractual. Respecto al contrato se considera necesario una explicación acerca de la definición de jóvenes, pues la misma varía dependiendo la ley o el Tratado que se va a tomar en cuenta, reconociendo que esta nueva modalidad se enfoca en un grupo determinado de personas en un rango de 18 y 26 años de edad. Por lo mencionado, el presente trabajo plantea como objetivo general, analizar el Contrato Joven y de Formación para poder conocer quién es el beneficiario real, mismo que se realiza a través de la aplicación de un enfoque metodológico cualitativo a través de análisis de contenido y observación.
La civilización de la atención y la memoria de los inmortales. Revisión de literatura científica 2019 -2023

En las dos últimas décadas hemos podido ser testigos de una situación bastante particular donde muchos estudiantes sufren de un proceso de desmemorización que en muchos casos los lleva a depender de muchos aparatos Smart, son estos aparatos tecnológicos, los que le están brindado una suerte de empoderamiento a la hora de poder recordar fechas tan simples como cumpleaños, inicio de clases, horarios y hasta poder responder a una pregunta tan sencilla como si hoy es sábado o domingo. Esta situación ha llevado a muchos estudios a nivel mundial sobre una suerte de involución de la memoria, que en palabras de Patino (2020) la definió como la civilización de memoria de pez, donde compara la memoria de un pez de tan solo ocho segundos, con el de atención que ha medido Google en los humanos promedio y que es de tan solo nueve segundos. Este escenario nos lleva a pensar que en la actualidad los cambios bruscos que experimentamos en cada segundo nos están conduciendo a compararnos con Joseph Cartaphilus, protagonista de cuento el Inmortal de Jorge Luis Borges, quien en su búsqueda de la inmortalidad llega sin saberlo a una ciudad atrasada en el tiempo, con una civilización a la que el describe como trogloditas, que no hablan, devoran serpientes, que no hacen nada por ayudarle y solo se limitan a observarlo. Estos trogloditas son inmortales aquellos que emprendieron mil proyectos, pero al saberse inmortales dejaron todo para después, jamás concluyeron nada y poco a poco empezaron a olvidar. Esta comparación por exagerada que pueda parecer se asemeja mucho a la nuestra realidad, vivimos en una suerte de civilización de los inmortales, aquellos que solo se limitan a observar las pantallas de su celular, aquellos que evitan emprender y concluir proyectos porque mañana lo pueden hacer y aquellos que poco a poco empiezan a olvidar y que culpan a sus aparatos tecnológicos de no haceres recordar.

La producción de bioles enriquecidos a través de biodigestores semicontinuos es la manera más eficaz y rápida de obtención ya que su ensamble y manejo son sencillos. La digestión anaeróbica es un proceso biológico que utiliza microorganismos para biodegradar la materia orgánica en ausencia de oxígeno, produce energía en forma de biogás y tiene como subproductos el biol y biosol que pueden emplearse en la agricultura como fertilizantes orgánicos. El objetivo de este trabajo fue obtener biofertilizantes enriquecidos en biodigestor semicontinuo para su uso potencial agronómico. Se determinaron dos formulaciones con un período de fermentación de 45 a 75 días en condiciones controladas. Los biofertilizantes obtenidos (F1 y F2) tienen un pH neutro (7.77 y 8.76). La formulación 2 es la que presenta mejores resultados en cuanto a macronutrientes (0.04% N, 0.01 % P, 0.28% K) y la formulación 1 para micronutrientes (21.9 ppm de Fe y 3.96 ppm de Mn).  En ambos bioles, se identificó a través de ensayos de fitotoxicidad el índice de germinación (IG), integrando el porcentaje relativo de germinación y el crecimiento relativo de raíces. Con la obtención y aplicación de biofertilizantes generados a través de residuos orgánicos de los procesos agrícolas y pecuarios se pretende disminuir los impactos ambientales generados por el uso de fertilizantes químicos.
