Authors: Pramanik Tapas , Sur Tapas Kumar
Published: January 2022

Novel corona virus disease (COVID-19), since its emergence in November 2019, took the toll of a huge number of human lives. It is a β-corona-virus also known as SARS-CoV2. The safest and most effective way to prevent the disease is definitely vaccination amongst the large population. To the best of our knowledge, more than 200 vaccine candidates for COVID-19 were developed by the scientists of research institutions and pharmaceutical companies and nearly 52 candidates were in human trials. Till now, only 15 vaccines are being offered to the general population in the world, out of which 2 vaccines are RNA, 6 are conventional inactivated, 5 viral vector and 2 protein subunit. Here, we tried to unfold the events and efforts behind the successes of new innovations of COVID-19 vaccines, the world has achieved yet.
Variation of bleeding time and clotting time in the ABO blood groups
Authors: Adhikari Manandhar Seerina , Amatya Mrigendra
Published: January 2022

Introduction: Blood grouping, bleeding time (BT) and clotting time (CT) are important hematological parameters investigated before any surgical procedure. The association of blood groups with many diseases are established, such as epistaxis with blood group “O”. This study aimed to assess the relationship of BT and CT among different blood groups and to find any gender difference in these parameters.

Materials and methods: A cross-sectional observational study was conducted among healthy medical students. Blood grouping was done by agglutination method, BT by Duke’s method, and CT by capillary tube method. Mean bleeding and clotting times (seconds) were compared among groups.

Results: The study was completed in 351 students (160 males, 191 females), with age ranging from 19-23 years. Both BT and CT values were highest in the blood type O, BT was lowest in type B, and CT was lowest in type AB, although the differences were statistically not significant (p>0.15). Females had higher values of BT as well as CT than males (p values <0.001). A very highly significant correlation between the bleeding and clotting times was also noticed (Pearson’s correlation coefficient, P = 0.495, p<0.001).

Conclusions: The study hinted a tendency for higher risk for hemorrhagic condition and lower risk for thrombotic event in blood group O compared to groups A, B or AB. Multicentric study including larger population with the emphasis on finding plasma vWF level may be helpful to verify findings, identify the risk groups, and take prior preventive measures.
On Karol Wojtyła’s Aristotelian Method Part II Induction and Reduction as Aristotelian Induction (ἐπαγωγή) and Division (διαίρεσις)
Authors: Wagner Daniel C.
Published: January 2022

This is the second of a two-part study treating Karol Wojtyła’s Aristotelian methodology. Having presented Aristotle’s method of induction (ἐπαγωγή/epagoge) and analysis (ἀνάλῠσις/analusis) or division (διαίρεσις/diairesis) in Part I, Part II discloses the logical form and force of Wojtyła’s method of induction and reduction as Aristotelian induction and division. Looking primarily to the introduction to The Acting Person, it is shown that Wojtyła utilizes the logical forms of reductio ad impossibile and reasoning on the hypothesis of the end, or effect-cause reasoning, which is special to the life sciences and the power-object model of definition as set down by Aristotle. By use of this Aristotelian methodology, Wojtyła obtains definitive knowledge of the human person that is necessary and undeniable: he discloses the εἶδος (eidos) or species of the person in the Aristotelian, Thomistic, and Phenomenological sense of the term.
Human Person in the Code of Canon Law of John Paul II
Authors: Přibyl Stanislav
Published: January 2022

The Code of Canon Law, promulgated by John Paul II in 1983, is a synthesis of the earlier 1917 Code and the doctrine of the Second Vatican Council. The Code contains norms which go well beyond a reform of the inner legal relations within the Catholic Church. A lot of them deal with the value and dignity of the human person, which shows a clear impact of the pontificate of John Paul II, who put a lot of emphasis on the given issue. The article discusses the fields of legal regulations in the Code which touch upon the issue of the human person, esp. freedom of religion, protection of unborn life, social rights, legal standing of women and the education of future generations. It points out the main difference between civil law (which also serves the dignity of the human person) and canon law, namely, the latter aims at the salvation of souls.

United States health care spending consumes nearly a fifth of the GDP [1]. While, in many respects, the U.S. health care system is enviable and highly innovative, it is also characterized by elements of ineffectiveness, inefficiency, and inequity. These aspects, resulting from pre-existing vulnerabilities within the system and interactions between the various stakeholders, were acutely highlighted by the COVID-19 pandemic. As health product manufacturers and innovators (HPMI) took steps to mitigate the immediate crisis and simultaneously begin to develop a longer-term sustainable solution, six common themes arose as areas for transformational change: support for science, data sharing, supply chain resiliency, stockpiling, and surge capacity, regulatory and reimbursement clarity and flexibility, public- and private-sector coordination and communication, and minimizing substandard care offerings. Within these categories, the authors of this paper suggest policy priorities to increase the effectiveness, efficiency, and equity of the HPMI sector and writ large across the U.S. health care system. These priorities call for increased scientific funding to diversify the pipeline for research and development, strengthening the nation’s public health infrastructure, building and maintaining “ever warm” manufacturing capacity and related stockpiles, instituting efficient and effective regulatory and reimbursement frameworks that promote innovation and creativity, devising structures and processes that enable more efficient collaboration and more effective communication to the public, and implementing rewards that incentivize desired behaviors among stakeholders. This assessment draws from the collective experience of the authors to provide a perspective for the diagnostics, hospital supplies and equipment, medical devices, therapeutics, and vaccines segments. While the authors of this paper agree on a common set of key policies, sub-sector-specific nuances are important to consider when putting any action priority into effect. With thoughtful implementation, these policies will enable a quicker, more robust response to future pandemics and enhance the overall performance of the U.S. health care system.

Authors: Cawthorpe David , Cawthorpe David
Published: January 2022

Objective: The study objective was to examine the relationship between dental caries diagnosed before the age of four and ICD diseases over a 16-year period.
Methods: The sample of approximately 33,531 (48% female) individuals having a total of 2,864,790 physician diagnoses over 16 years comprised a the cohort two groups, one with (2.7% of the sample) and one without dental caries (dependent variable) that were under the age of four years in the first two years of the sample data. Categories of dental caries and associated gingivitis and periodontal disease were based on the International Classification of Disease (ICD Version 9) diagnostic codes 521-523. The sample was described. Odds ratios comparing those with and without dental caries and the main ICD classes were calculated. Additionally, the ratio of each ICD diagnosis frequency comparing the cohort groups were calculated and represented the diagnoses assigned over the first 15 physician visits.
Results: Males had proportionally more dental caries diagnosed. Diagnoses were made predominantly by general practitioners. Within the dental caries cohort group, associated ICD diagnoses were over-represented in both odds ratios and within individual ICD diagnoses on the first diagnosis and over the first 15 diagnoses in time.
Conclusion: Dental caries diagnosed in very young children before the age of four are associated with multi-morbidity over subsequent years. Sex differences and patterns of associated morbidity may contribute to a better understanding of early life vulnerability to dental caries and their sequelae.

Authors: Irfan Ashraf Muhammad , Arfan Lodhi Muhammad
Published: January 2022

Within the context of lockdown and pandemic situation, by taking all these conditions in attention, government of Punjab introduced compact and shortened curriculum named as Accelerated learning program for 8th grade students. The accelerated syllabi are usually introduced and implemented to fulfill short term objectives. The current study aimed at investigating how efficient and effective this ALP can be in achieving estimated language proficiency of students. Furthermore, there is some need to get awareness to teachers’ preference and their ALP teaching practices meeting the desired aims. The syllabus has been introduced to minimize the Covid-19-driven learning loss and expedite the teaching and learning procedures to damage control and maximize learning outputs. Therefore, current study was designed as experimental so that researchers can check the impact of ALP on students’ achievements. Moreover, the effect of the independent variable ALP course was checked upon the English proficiency of the learners which is termed as a dependent variable. The 8th grade students at government schools of Bahawalpur district were taken as the population of the study out of which only 60 students were selected by using a random sampling technique and 80 teachers were also selected by using a purposive sampling technique. The findings of the study indicate that there is little or no impact on students’ learning outcomes by the use of ALP course for teaching English language. It is also found that teachers face difficulty while teaching through ALP because it is too compact and it did not include all the language components and skills. In order to obtain the maximum output from ALP, it is suggested to devise comprehensive lesson planning and proper teaching strategies with revised and modified pattern of learning outcomes.

Published: January 2022

This paper presents an overview of sociolinguistics by examining the fundamental concepts and issues therein. Research efforts in sociolinguistics focus on speakers and their exploration of language to cope with their daily communicative goals in society. The innate potential of language to cope with a wide range of phenomena to be expressed by speakers is incredible. Indeed, the repertoire of language is not exhaustive. Speakers express cultural norms, political issues, legal discourses, religious messages and scientific facts by using a linguistic system of communication – language. Sociolinguistics is the study of language and society. It elucidates the co-existence of different languages in society. Within a social structure, there are varieties of languages which contribute to the linguistic system and facilitate choice-making. Sociolinguistics is about language and society. In this study, we introduce sociolinguistics by examining language (its definition, functions and varieties), society, speech community and other phenomena that are on the front-burner in the literature.

Authors: Mahajan Renuka , Gupta Pragya
Published: January 2022

In recent years, COVID-19 vaccine-related issues and viewpoints have aroused significant anxiety and concern. Several research studies are extracting, tracking, and evaluating prevalent public opinions on social media and making efforts to curb the misinformation spread. But, there is still a large audience that perceives vaccination as a threat, which in turn reduces our ability to fight effectively against the pandemic. This bibliometric study aims to explore the distribution of capabilities of researchers, institutions, and countries, research themes, and frontiers of Covid-19 vaccine-related misinformation trending on social media since the rollout of these vaccines. The Scopus online database was used for analysis. Excel 2016 and VOSViewer (version 1.6.17) software were used to report the visualizations of infodemic literature on COVID Vaccine on social media. Annual publications, top contributing authors, top-cited journals and author affiliation, leading subject areas, the top country in publication, and keyword network were among the key findings. Future researchers can use these findings to create a baseline before studying Covid-19 vaccine misinformation on social media. Furthermore, it may help in compiling crucial knowledge, trends, and lessons from existing researches to provide useful insights to handle similar phenomena in the future.

Published: January 2022

The purpose of this study has been to determine the role of operating subsidies in shaping the economic situation of agricultural farms in the years 2014-2019. Secondary data originating from the database of accounting books of farms aggregated by the Polish FADN were taken for our analysis. The data were processed through an analysis of the dynamics of changes in 2014-2019. The results showed that operating subsidies reached an average of between 41% and 282% of the value of income earned by family-owned farms. It was found that whether or not farms were able to earn a financial surplus without resorting to subsidies depended on the economic size of a farm. The smallest and the largest farms were unable to cover their costs and earn a profit without having access to additional sources of funds.

Uncertainty of data during environmental monitoring prevents with confidently and objectively assessing the current condition of the environment, the influence of factors affecting the fuel consumption of vehicles during operation. In addition, it creates a serious problem in assessing the dynamics of this condition, especially when it comes to relatively small levels of pollution that are on the verge of the sensitivity of systems and devices in the car. It is precisely these tasks that include the determination of atmospheric pollution by emissions from road transport in conditions of variable weather and climatic conditions, carrying out routine maintenance, changing a configuration of an engine or transmission. The article discusses: a) factors related to the characteristics and vehicle systems, with the maintenance of vehicles. This category focuses on fuel consumption and CO2 emissions, which depend on the technical and operational characteristics of the vehicle, its weight and aerodynamics, tires and auxiliary systems, the quality and timeliness of maintenance and repairs; b) factors related to the environment and traffic conditions (weather conditions, road morphology and traffic conditions); c) factors related to a driver of a vehicle (driver qualifications, driving style). Optimization of factors related to vehicle systems and their characteristics has been performed; by using fuel of optimum quality and driving efficiently, you can achieve savings in fuel (financial) consumption and CO2 emissions. The article proposes the solution to a complex problem of managing the transport process while minimizing fuel consumption and CO2 emissions from passenger cars, depending on the road and climatic conditions and the driver's qualifications, based on the theory of fuzzy sets. This approach made it possible to largely compensate for the lack of objective information about the process due to its uncertainty by subjective expert data.
Influence of the position of the center of mass of a trailer category O1 on the stability of the road train

In a number of operational properties of motor vehicle (ATZ) at the tendency of increase of speeds of movement the most important indicators of the kept quality, in any modes, are stability and controllability. The choice of constructive parameters of ATZ providing these properties increases active safety of operation and reduces probability of road accidents during the execution of transport operations. From the point of view of practical purposes at operation of ATZ not only the reason of infringement of stability becomes important, and reaction of ATZ to it and control actions of the driver which are ambiguous and unstable. Therefore, it is assumed that the stability and controllability of the ATZ movement should be provided by the design parameters of the machine itself. The result of the analysis of the course stability of the road train was the expression of the critical speed of rectilinear motion. According to the developed mathematical model, the critical velocity is determined. Calculations were made for a road train consisting of a VAZ-2107 car and the uniaxial trailer for different loads of the trailer and different location of its center of mass. According to the initial data inherent in the nominal load of the car and the maximum load of the trailer and the location of the center of mass of the trailer on the longitudinal axis and in the center of mass of the loading platform, the critical speed is about 36 m/s (129.6 km/h). In transient modes of movement, such as "entering the circle and moving in a circle", "jerk of the steering wheel", "shift", "snake", displacement of the center of mass of the trailer in both the longitudinal and transverse planes, the critical speed decreases, and more significantly reduction occurs when the transverse displacement of the center of mass. Thus, if at the maximum displacement of the center of mass of the trailer on the x-axis (x = -0.75 m) the rate of oscillation instability decreases by 36.4% (Gn = 350 kg), 38.4% (Gn = 500 kg) and 44.3% (Gn = 750 kg) in comparison with this speed in the absence of displacement, then at the maximum displacement along the y -axis in the rate of oscillation instability decreases by 45.4%, 55.2% and 63.6%, respectively. In the case of such a trailer loading, the center of mass of the trailer shifts along both the x-axis and the y-axis, there is a further decrease in both the critical speed of the road train and the rate of oscillation instability. This must be taken into account when loading the trailer.

Published: January 2022

The efficiency of a car is considered through the amount of energy loss spent on transmission from the engine to the driving wheels of the car. Analytical and experimental methods for assessing mechanical losses are analyzed. The advantages and disadvantages of road and bench tests of a car in free run modes are indicated. A description of the diagnostic equipment - a stand with running drums, used to simulate the movement of a car in laboratory conditions is given. The components of the necessary measuring equipment for recording the speed and torque on the wheels of a car are considered. The list of primary measuring sensors and main transducers is indicated, which transmit information to the computer. The results of the car run-out on the stand are given: the change in the instantaneous speed from time to time. The primary assessment of the regression model is made and the values of the coefficients are obtained by the method of least squares of deviations of the vehicle speed. A mathematical model for the subsequent processing of experimental data has been developed. The purpose of mathematical modeling is to separate mechanical losses by power units separately for the engine, transmission and car wheels. An assessment was made of the amount of energy losses in the stand itself with running drums. The characteristic of the stand has been obtained, which must be taken into account in the measurement procedure. The results of experimental studies for the GAZ-31029 car are presented. The results of the influence of the technical condition of transmission units and vehicle wheels on the value of the power of mechanical losses are presented. Car tire pressure studies have been conducted. The graphical dependences of the power of mechanical losses depending on the speed of the car are obtained. Recommendations have been developed for diagnosing the general condition of the vehicle by the amount of mechanical losses at the stand with running drums. The ways of further improvement of the method are given. The main conclusions based on the research results are formulated.

The ability to move on different types of soils is one of the main indicators of the efficiency of mobile vehicles in off-road conditions. The movement of such special mobile machines is carried out due to the interaction of the propulsion with the support surface. Therefore, significant reserves to increase productivity and reduce the cost of technological and transport works are laid in reducing energy consumption when the engine interacts with the surface. On the process of interaction of the wheel drive with the deformable support surface it is established that the parameters of this interaction depend on a number of factors: normal load, angular velocity and torque. In the General case, the parameters of interaction of each engine change when changing the mode of movement of the wheeled vehicle, and the ability to change the air pressure in the tires when driving on different support surfaces allows to increase the performance of the wheeled vehicle In the study of the caterpillar, it was found that the pitch of the caterpillar, the stiffness of the caterpillar, the angular stiffness of two adjacent tracks, reducing the pitch of the caterpillar chain, reducing the stiffness of the caterpillar, increasing the angular stiffness of two adjacent tracks, affect the efficiency of the machine. The scientific novelty of the study is to develop a method of choosing the engine of a special mobile machine that works off-road, in the process of its design. Wheel or crawler solutions will mainly determine the performance and efficiency of special purpose vehicles. The choice of engine for special mobile machines is based on a set of criteria. The criteria determine the importance of the implementation of the tasks in relation to the efficiency of functioning. Knowing the sowing capacity of the soil, and taking into account the possibility of movement of a particular special mobile machine depending on the type of soil, you can choose one or another type of engine.

The article considers the architecture of conceptual modeling of the knowledge base, which creates a model of the subject area in the form of many concepts and relationships between them. This approach is based on the concept of a mobile software agent, which is implemented and functions as an independent specialized computer program or an element of artificial intelligence. Ensuring the use of subject area knowledge has become one of the driving forces of the recent surge in the study of artificial intelligence. For example, for models of many different subject areas it is necessary to formulate the concept of time. This representation includes the concepts of time intervals, time points, relative measures of time, etc. If one group of scientists develops a detailed knowledge base, others can simply reuse it in their subject areas using their own database. Creating explicit assumptions in the subject area, which underlie the implementation, makes it easy to change the assumptions when changing our knowledge of the subject area. The process of conceptualization of TO and P, first of all, involves the development of databases in research areas for the formalization and systematization of knowledge about the characteristics of this area of entities and phenomena. That is, the use of concepts in the field of maintenance in a consistent manner in relation to theories of knowledge. Ultimately, the paper updated mathematical modeling, algorithmization and implementation of intelligent systems in the field of maintenance, which will help automate the process of diagnosis and inspection of all car systems, facilitate fault prevention and improve the maintenance process and modernize the maintenance system itself. The approach of algorithmization of the base of knowledge of a condition of the car in each moment of time considered in work gives the chance to reduce time of stay of the car in the service center and to reduce considerably expenses for passing of MOT at service of cars.

World military conflicts show that the armor protection of most light armored vehicles does not meet modern requirements. The constant development and improvement of fire weapons makes it necessary to search for new constructive solutions in this area. Increasing the level of armor protection by increasing the thickness of the armor is a hopeless path, since it will lead to an increase in the mass of the vehicle, and this, in turn, will negatively affect the power plant and chassis. One of the ways to increase the level of protection is the use of new booking schemes using modern armored materials. This article analyzes publications devoted to modern scientific research related to the development and improvement of armor protection for light armored vehicles, as well as an analysis and assessment of options for the use of modern armored materials and various structures to protect vehicle crews and increase the level of tactical and technical characteristics. It is shown that at present, in connection with traditional approaches in the design of armored vehicles, the advantage is given to armored steels, aluminum and titanium alloys. However, there is a trend towards the use of lighter ballistic materials such as ceramics and composites with polymer fibers. The basis for the creation of reliable armor protection for lightly armored vehicles has been determined – the development of new promising structures for combined protection using new armor materials and their various options. Variants of additional armor protection systems of both foreign manufacturers and domestic developments are presented. The new systems include several special materials that differ from each other in a wide range of physical and mechanical properties. The use of such protection, together with the main armor, can reduce the mass performance of the vehicle. It has been determined that the creation of new designs of armored elements using the most modern technologies will lead to a significant increase in the protective characteristics of the armor of light armored vehicles.

Wydaje się, że dla wielu młodych ludzi i dorosłych Polaków odnajdywany i deklarowany sens życia wiąże się z celami bliższymi, nie dosięga metafizycznej głębi ludzkiej egzystencji. Wartości afiliacyjne i potrzeby samorealizacji poprzez bezpośrednie kontakty z ludźmi w małych grupach nabierają niejednokrotnie charakteru wartości naczelnych. W sytuacji, gdy konkretne wartości wiążą się z wieloma sensami, nie jest łatwo stworzyć spójną strukturę sensu w swoim życiu.

This paper aims to analyse the influence of the demographical factors on the short-term sustainability of the pension system from Romania. The data used for econometric modelling consisted of panel data for the period 2009-2019 for 8 European Union member states, together with time series data for autoregressive modelling. The following econometrical models were used: random-effects GLS regression and Box-Jenkins (ARIMA). The results emphasize an increasing demographical pressure on the Romanian pension system and the need of pension system reform.

Published: January 2022

African American/Black adults are twice as likely to have Alzheimer’s disease (AD) compared to non-Hispanic White adults. Genetics partially contributes to this disparity in AD risk, among other factors, as there are several genetic variants associated with AD that are more prevalent in individuals of African or European ancestry. The phospholipid-transporting ATPase ABCA7 (ABCA7) gene has stronger associations with AD risk in individuals with African ancestry than in individuals with European ancestry. In fact, ABCA7 has been shown to have a stronger effect size than the apolipoprotein E (APOE) ɛ4 allele in African American/Black adults. ABCA7 is a transmembrane protein involved in lipid homeostasis and phagocytosis. ABCA7 dysfunction is associated with increased amyloid-beta production, reduced amyloid-beta clearance, impaired microglial response to inflammation, and endoplasmic reticulum stress. This review explores the impact of ABCA7 mutations that increase AD risk in African American/Black adults on ABCA7 structure and function and their contributions to AD pathogenesis. The combination of biochemical/biophysical and ‘omics-based studies of these variants needed to elucidate their downstream impact and molecular contributions to AD pathogenesis is highlighted.
Assessing most productive scale size with fuzzy stochastic data envelopment analysis

Published: January 2022

Classic data envelopment analysis (DEA) is a linear programming method for evaluating the relative efficiency of decision making units (DMUs) that uses multiple inputs to produce multiple outputs. In the classic DEA model inputs and outputs of DMUs are deterministic, while in the real world, are often fuzzy, random, or fuzzy-random. Many researchers have proposed different approaches to evaluate the relative efficiency with fuzzy and random data in DEA. In many studies, the most productive scale size (mpss) of decision making units has been estimated with fuzzy and random inputs and outputs. Also, the concept of fuzzy random variable is used in the DEA literature to describe events or occurrences in which fuzzy and random changes occur simultaneously. This paper has proposed the fuzzy stochastic DEA model to assess the most productive scale size of DMUs that produce multiple fuzzy random outputs using multiple fuzzy random inputs with respect to the possibility-probability constraints. For solving the fuzzy stochastic DEA model, we obtained a nonlinear deterministic equivalent for the probability constraints using chance constrained programming approaches (CCP). Then, using the possibility theory the possibilities of fuzzy events transformed to the deterministic equivalents with definite data. In the final section, the fuzzy stochastic DEA model, proposed model, has been used to evaluate the most productive scale size of sixteen Iranian hospitals with four fuzzy random inputs and two fuzzy random outputs with symmetrical triangular membership functions.
