Dynamics of a single predator multiple prey model with stochastic perturbation and seasonal variation
Authors: Hui Hong-Wen , Nie Lin-Fei
Published: November 2021

Considering various factors are stochastic rather than deterministic in the
evolution of populations growth, in this paper, we propose a single predator
multiple prey stochastic model with seasonal variation. By using the method
of solving an explicit solution, the existence of global positive solution
of this model are obtained. The method is more convenient than Lyapunov
analysis method for some population models. Moreover, the stochastically
ultimate boundedness are considered by using the comparison theorem of
stochastic differential equation. Further, some sufficient conditions for the
extinction and strong persistence in the mean of populations are discussed,
respectively. In addition, by constructing some suitable Lyapunov functions,
we show that this model admits at least one periodic solution. Finally,
numerical simulations clearly illustrate the main theoretical results and
the effects of white noise and seasonal variation for the persistence and
extinction of populations.

Terminals obtained from spent lead-acid batteries in Mexico contain around 2 wt% Sb. The terminals were melted in an electric furnace and then oxygen was injected at 750 ?C with a gas flow rate of 2 L/min to produce high purity Sb2O3. The antimony trioxide obtained was treated with a mixture of Na2CO3-SiC at 1000 ?C to obtain metallic antimony. The antimony trioxide was reduced by C present in reagents while silicon and sodium formed a slag phase. The amounts of Sb2O3 and SiC were held constant while the Na2CO3 was evaluated in the range from 30 to 42 wt%. The produced antimony and slag were characterized by the X-ray diffraction and SEM-EDS techniques. The addition of 34 wt% Na2CO3 led to the recovery of antimony up to 90.16 wt% (99.57 wt% purity) and the lowest antimony losses in the slag (2 wt%). In addition, the compounds Na2SiO3 and Na2Si2O5 formed in the slag indicated a more stable slag. Na2CO3 contents higher than 38 wt% decreased the antimony recovery since Na2Sb4O7 compound was promoted in the slag. The oxidation and reduction process was modeled in FactSage 7.3 software for a better understanding of the Na2CO3 and SiC additions on the antimony recovery rates and compounds formed in the slag.
On the mountain-river-desert relation
Authors: Mei Ying , Liu Yu-Qi , He Ji-Huan
Published: November 2021

When the Yellow River flows through Togtoh, north China, a puzzling phenome-non occurs, one side is the Hobq desert, and the other side of the river is a lush landscape of gardens. No theory can explain the desertification beside a river. Especially the river might be the main factor in the desertification. We address this challenge by establishing a mathematical model that can depict the different effects of the river and mountain on the river's both sides. The model herein takes into account the different meteorological parameters and soil parameters of the river?s both sides and Earth surface's morphology. Moreover, though our focus is put on the Hobq desert, the present theory on mountain-river-desert relation can also be used for combating desertification. We anticipate that the mountain-river-desert relation is much more important than vegetation restoration and human activity.

Published: November 2021

Objective: To evaluate the effect of multi-grip myoelectric prosthetic hands on performance of daily activities, pain-related disability and prosthesis use, in comparison with single-grip myoelectric prosthetic hands.
Design: Single-case AB design.
Patients: Nine adults with upper-limb loss participated in the study. All had previous experience of single-grip myoelectric prostheses and were prescribed a prosthesis with multi-grip functions.
Methods: To assess the changes in daily activities, pain-related disability and prosthesis use between single-grip and multi-grip myoelectric prosthetic hands, the Canadian Occupational Performance Measure, Pain Disability Index, and prosthesis wearing time were measured at multiple time-points. Visual assessment of graphs and multi-level linear regression were used to assess changes in the outcome measures.
Results: At 6 months’ follow-up self-perceived performance and satisfaction scores had increased, prosthesis wearing time had increased, and pain-related disability had reduced in participants with musculoskeletal pain at baseline. On average, 8 of the 11 available grip types were used. Most useful were the power grip, tripod pinch and lateral pinch.
Conclusion: The multi-grip myoelectric prosthetic hand has favourable effects on performance of, and satisfaction with, individually chosen activities, prostheses use and pain-related disability. A durable single-grip myoelectric prosthetic hand may still be needed for heavier physical activities. With structured training, a standard 2-site electrode control system can be used to operate a multi-grip myoelectric prosthetic hand.
Uneven hardness mechanism and related fracture characteristics in laser-MIG hybrid welded Al–Mg–Si alloy butt
Authors: Zhu Minqi , Yang Shanglei , Bai Yishan , Fan Cong
Published: November 2021

In this paper, a 6082-T6 high-strength aluminum alloy with 5 mm thickness was taken as the research object. The TRUMP Trudisk 10002 disc laser and the Transpils synergic 4000 welder were used to weld it by laser-Metal-Inert-Gas composite welding. The property transition and uneven hardness of the base metal (BM), the heat affected zone (HAZ), and the partially melting zone (PMZ) were analyzed by a transmission electron microscope, a scanning electron microscope, and an energy dispersive spectrometer. The results showed that: grain coarsening was not the main reason for softening in the HAZ but the evolution of precipitates is the main reason. Precipitates annexation in HAZ was the main reason for hardness decrease in the HAZ. Solid diffusion occurred in PMZ, and the enrichment of main strengthening elements at grain boundary played a positive role in hardness recovery. A large number of spherical GP zones and the β″ phase had been found in the PMZ, which played a major role in strengthening and increased the hardness of the PMZ. The tensile results showed that the BM had the highest elongation and tensile strength. The strength and plasticity of the HAZ were lower than those of the BM. A lamellar second phase with lamellar tearing was found at the bottom of the fracture in HAZ. The softening fracture morphology was different from that of the BM. This paper mainly focuses on the softening of HAZ of welded joints and the hardness bump in PMZ. The distribution of precipitates, grain size, alloy element diffusion distribution, and mechanical properties were analyzed. The uneven hardness behavior of the joint and its influence on mechanical properties were further revealed.

Highly efficient welding of pure copper was achieved using a hybrid laser system, which combined a blue diode laser and a single-mode fiber laser. Pure copper is used as a motor coil for electric vehicles (EVs). However, the processing efficiency of laser welding for pure copper is low since it has a low light absorption rate for the wavelength of the fiber laser. In this study, a hybrid laser system, which combined coaxially with a blue diode laser and a high-power single-mode fiber laser, was developed to realize highly efficient laser welding for pure copper. The beam profile of hybrid laser was alimented to set a stair-shape beam at the processing point. To investigate the effect of the beam profile, the hybrid laser was irradiated onto a 3 × 3 × 20 mm3 copper wire for welding, and the molten volume of copper wire was evaluated. As a result, it was found that the molten volume with a blue diode laser became 1.8 times larger than that without it. Moreover, the welding efficiency of the hybrid laser was 1.45 times higher than that of the fiber laser only.

The article considers the basic principles of professional ethics of educational experts in conducting institutional audits of educational institutions, including the rule of law, public interest as the main criteria of professional activity of an expert, professional competence, exclusion of self-profit actions, objectivity and independence, confidentiality of information, etc. The rules of interaction with representatives of educational institutions engaged in educational activities are presented. Emphasis is placed on the psychological aspects of business relations and relationships with colleagues. It is noted, that the work of an educational expert does not only require comprehensive knowledge of legislation in the field of education, but also includes certain moral obligations based on generally accepted norms, which guide the expert in conducting institutional audits in educational institutions. The Code of Professional Ethics of an institutional audit expert in educational institutions is a set of moral and ethical obligations and requirements based on generally accepted norms, which experts have to follow during the institutional audit procedure in educational institutions. The following theoretical research methods were used to solve certain problems: systematic analysis, comparison, systematization, classification and generalization of scientific and methodological literature on the problem; method of systematic analysis of philosophical, psychological-pedagogical, sociological literature for theoretical generalization of leading scientific approaches; interpretation of key provisions of the study.
EVOLUTION OF PSYCHOLINGUISTIC THEORIES IN WORD-MAKING PROCESSES
Authors: Diukar Kateryna
Published: November 2021

This article analyzes the evolution of linguists' views on the psycholinguistic nature of the grammatical structure of language, in particular the word-formation system, from single observations and individual thoughts of scientists to specialized studies of monograph and dissertation level. The question of singling out grammar, including word-formation, as a self-sufficient object of research in the context of the formation of psycholinguistics as an autonomous scientific branch is considered. Attention is drawn to the fact that Ukrainian academic community is less interested in psycholinguistic aspects of word-creation of an individual than their foreign colleagues. The problem of analysis of word-formation innovations from the point of view of modern psycholinguistic concepts is touched upon. A special interest of psycholinguists to consider children's speech word-creation, as well as derivational features of an individual's speech during ontogenesis is highlighted. Mention is made of the empirical side of considering word-formation as a complex psycholinguistic process of verbal unit generation and reception. It is indicated on the remarkable promise and importance of this scientific field for further research, especially in the aspect of expanding the theoretical and methodological basis for further empirical study and description of the psycholinguistic nature of wordsmithing.
PARADIGM TRANSFORMATIONS OF THE VAMPIRIAD OF THE END OF THE XX – THE BEGINNING OF THE XXI CENTURY IN THE DILOGY “EMPIRE‘’V’” – “BATMAN APOLLO” BY VICTOR PELEVIN
Authors: Gurduz Andriy
Published: November 2021

The modern vector of transformations of the artistic image of a vampire is of special interest and agrees with what we have seen since the end of the XX century – the tendencies of consistent sympathy of writers to legendary-mythological images with traditionally negative symbolic meaning. V. Pelevin’s dilogy “Empire ‘V’” – “Batman Apollo” is organic to the tendencies of the modern world vampiriad and reflects the paradigmatic changes of this corpus of interpretations. The purpose of our article is for the first time to define the paradigmatic transformations of the artistic vampiriad of the end of the XX – the beginning of the XXI century and to determing of their reflection in the dilogy “Empire ‘V’” – “Batman Apollo” by V. Pelevin. Also we identify two interrelated basic clusters in the evolution of the vampire image for the first time: the justification and exaltation of this image in the literature, and the embodiment of aspects of national identity in it. V. Pelevin combines artistic and documentary discourses, in his fantasy world he paradoxically synthesizes historiosophical reflections on the fate of the people and appeals to various moments in the history and modernity of his country. The novelty and politicization of the Pelevin’ text is an innovation for the vampiriad, although in the fantasy genre the reception of national social realities is now becoming typical.
EVOLUTION OF ALDOUS HUXLEY'S OUTLOOK
Authors: Karaeva Irina
Published: November 2021

The evolution of Aldous Huxley's outlook is considered in terms of cultural studies. The metaanthropological approach traces how the artist's attitude to the human personality and its place in the universe was changing. A comparative analysis of the artist's works from different periods of creative activity shows that along with the evolution of the artist’s outlook, the outlook of his characters was changing. It is shown how the spiritual searches of A. Huxley and his characters developed from the ordinary level of outlook in early novels, through personal one in novels that offer an anti-utopian model of culture, to the philosophical level of outlook in the Island novel. It was found that the outlook of his characters from the early period of the artist's work is limited by the framework of ordinary being and outlook, which leads to the lack of self-confidence, the impossibility to make decisions, the inability to think creatively. In those novels which offer an anti-utopian model of culture the characters' outlook gains the features of independence, critical thinking, creativity, self-knowledge and self-improvement, which means achieving a personal level of both outlook and being. In the Island novel the outlook of A. Huxley’s characters gains the hallmarks of philosophical outlook, which inner integrity, harmony and creative character are typical for. This analysis embraces A. Huxley's early novels from the 1920s and 1930s, philosophical novels offering anti-utopian models of culture, and the last philosophical novel Island.

Published: November 2021

Features of preparation of future teachers for carrying out of interactive training technologies in the course of the organization of leisure activity in the conditions of rest in summer camps are examined. It is noted that various forms of leisure activities in the summer camp can support the emotional health of children, overcome their own shortcomings, form the will and character. Advice and methods for conducting the case method are given: selection of material (material should be selected in such a way as to reflect the problems that participants may face in real life); the availability of alternatives (the situation around which the discussion takes place should have been sufficiently diverse and have several solutions). The advantages of the case method are described: realism (the use of this method significantly complemented the theoretical aspects of the problem); pressure reduction (case method gave a unique opportunity to study complex or emotionally significant issues in a safe training atmosphere, not in real life, with real threats and risks in case of making the wrong decision); active interaction (communicative nature of the method provided an opportunity to provide a quick but very important assessment of the issues under discussion and the proposed solution). It is proved that interactive pedagogical technology in the process of organizing leisure activities of a person (as a set of a series of consecutive actions aimed at achieving a result) was based on the principles of voluntariness, positivity, responsibility, partnership.
AESTHETIC ASPECT OF EMOTIVENESS OF POETIC TEXT
Authors: Redka Inna
Published: November 2021

The study looks for ways of analyzing the aesthetic aspect of emotiveness in a poem. To accomplish the aim, the author undertakes an attempt to study the essence of the image of aesthetic feeling. Since a poetic text appears to be a complex unity of notional, emotive, and aesthetic codes, the methods of cognitive analysis are employed to formalize deep cognitive and emotive constructs that give rise to aesthetic senses within a poetic text. The study relies on the statement that an image of aesthetic feeling has an emergent nature which means that it appears in the process of poetic text writing as a result of a creative impulse of the author (O. Mandelstam). In the study, the image of aesthetic feeling is regarded as an emotive image of the highest level. On the one hand, it is directed at some well-established aesthetic categories, and on the other, it reveals the author’s attitude to them which is manifested through a sophisticated network of images. A step-by-step analysis of Shel Silverstine’s poem “A Light in the Attic” has been suggested to illustrate a possible way of uncovering image(s) of aesthetic feelings inscribed in the text.
STRUCTURAL AND FUNCTIONAL ORGANIZATION OF PERSONALITY REFLEXIVE COMPETENCE IN MODERN PSYCHOLOGY
Authors: Illiuschenko Serhii
Published: November 2021

This article is a theoretical study of the “reflexive competence” concept and other related notions in the context of psychological science. Reflexive competence is viewed as an important component of professional competence and a separate formation of mind that determines the resultant aspect of reflexive activity. The study is based on the analysis of non-fiction works on the subject matter written by Ukrainian and foreign authors. It shows the diversity of approaches to definition of the “reflexive competence” concept and to detailing of the aspects of its structure. The article describes the types of reflection and examines every single component of reflexive competence, including cooperative, communicative, personal and intellectual reflection. It also looks at the models of reflexive competence and its individual structural components, such as informational, instrumental, judgmental and motivational, and behavioral. The article explains why we need to study reflexive competence as a complex formation – a meta-concept, a personal meta-competence that integrates knowledge, abilities and skills acquired in the course of personal growth and associated with the realization of why people do what they do, with identification and resolution of problems that arise in the course of our primary activity, and with the setting of goals and prioritization of personal growth areas. The work also proves the importance of reflexive competence as a professional growth driver for the officers of Ukraine armed forces and an aspect that facilitates development of other kinds of personality competence.
OVERCOMING SOCIAL ALIENATION IN MARXIZM AND POST-INDUSTRIAL THEORY: A COMPARATIVE ANALYSIS
Authors: Putin George
Published: November 2021

The article is devoted to the reflection of processes in the economy associated with intangible capital on social development. The author focuses on the problem of social alienation, formulated by Marx, and the possibilities of overcoming it, which are opening up in connection with the transition of the economy to the production of intellectual values. Using the method of comparison, the author explores how this problem is solved by representatives of two philosophical trends – post-industrialism (D. Bell, V.L. Inozemtsev, A. Toffler) and neo-Marxism (V.V. Orlov, J. Baudrillard, A.V. Buzgalin, A. Gorz). Both of them believe that the production of knowledge is incompatible with the commodity nature of the industrial economy. However, supporters of the post-industrial concept believe that overcoming the commodity form is possible within the framework of reforming capitalism, while Marxists argue that the «knowledge economy» is achieved only by transforming of social relations. In addition to the actual economic aspects of this issue, the article examines the problems of creative labor, consumer society, relations between people, conflict of values through the prism of alienation.
FEATURES OF ARTERIAL HYPERTENSION COMBINED WITH OBESITY ACCORDING TO NON-ALCOHOLIC FATTY LIVER DISEASE (STEATOSIS AND STEATOHEPATITIS)
Authors: Bochar Olesia , Bochar Volodymyr
Published: November 2021

This research was aimed to estimate the course of hypertension on the background of obesity and nonalcoholic fatty liver disease according to its stages (steatosis and steatohepatitis). Ninety patients were evaluated for anthropometric, general-clinical, laboratory, instrumental and immune-enzymatic research methods. With USG, the most characteristic features of fatty liver infiltration and the criteria for the distinction of steatosis from steatohepatitis were revealed, and on the basis of them 2 groups were formed. Thus, the progression of nonalcoholic fatty liver disease to the stage of steatohepatitis was accompanied by a more pronounced increase in blood pressure larger in comparison with steatosis of mass index of myocardium and anterior-posterior size of the left atrium, indicating the progression of structural myocardial disorders. Therefore, the presence of non-alcoholic steatohepatitis in patients with hypertension can be regarded as unfavorable prognostic criteria for the development of heart failure. In the presence of steatohepatitis, more marked changes in lipidograms were noticed for Low-Density Lipoprotein and Triglyceride values and a violation of the functional state of the liver with a cytolytic syndrome on the activity of AST and ALT and the total bilirubin, which may contribute to the progression of liver damage.

Published: November 2021

Background: Occupational exposure to metal dust particles leads to irritation and initiation of inflammatory responses in the respiratory system that subsequently onsets lung diseases. Lathe machine workers have a greater risk of having lung diseases due to continuously conducting metal dust particles. This study aimed to explore the pulmonary health status of lathe machine workers. Methods: In this cross-sectional study, 80 individuals (lathe workers) were adopted from a different area of the Tangail district in Bangladesh. A questionnaire’s survey was accomplished along with oximetry and spirometry. After that, blood was drawn for measuring Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), and Immunoglobulin E (IgE) test to the lung function abnormalities. Results: Among 80 lathe machine workers, 12% had breathing problems, 13.8% had coughing, 16.2% had to sneeze and 8.7% had a chest. In addition, spirometry results including, FVC, FEV1, FEV1%, PEF, PEF%, FEF25, FEF75, and FEF2575 were significantly lower in lathe workers compared to control. Moreover, higher levels of IgE (264.93±141) and ESR (11.5±4.77) were reported in lathe machine workers than in the control group. Not using protective masks and smoking were considered as risk factors for having respiratory diseases in lathe machine workers. Conclusion: This study concludes that exposure to metal dust particles can cause respiratory disease symptoms and lower pulmonary function in lathe machine workers. Furthermore, metal dust might also augment the blood IgE and ESR level.

Aiming at the problem of long signature generation and verification time caused by low operation efficiency in ring signature algorithm based on composite order group, an asymmetric identity based ring signature scheme based on prime order group is proposed. The model definition and specific identity based ring signature scheme design of the proposed scheme are described, and the correctness and security of the proposed scheme are analyzed. Finally, the efficiency of the core operation part of the algorithm is explained. Compared with the correlation signature algorithm based on composite order group, the optimization has a great improvement in operation overhead and performance, and the designed scheme is unforgeable. The designed signature scheme meets the unconditional anonymity and unforgeability of ring signature.
Tietojärjestelmien avulla kerätyn tiedon hyödyntämisen esteet sosiaalialan organisaatioiden tiedolla johtamisessa

Published: November 2021

Tietojärjestelmien avulla kerätyn datan hyödyntämistä tiedolla johtamisessa pidetään tärkeänä sosiaalialan tuottavuuden ja vaikuttavuuden lisäämiseksi. Datan hyödyntämisessä on kuitenkin koettu esteitä, vaikka dataa onkin saatavilla. Datan hyödyntämistä on viime aikoina tuettu valtakunnallisesti strategiatyöllä, hankkeilla, kehittämällä lainsäädäntöä sekä uudistamalla kansallista tietoarkkitehtuuria.
Artikkelissa tarkastellaan datan avulla jalostetun tiedon hyödyntämistä tiedolla johtamisessa. Artikkeli on osa valtakunnallista sosiaali- ja terveydenhuollon tietojärjestelmäpalveluiden seurannan ja arvioinnin hanketta ja siinä tutkittiin sosiaalialalla toimivien julkisten, yksityisten ja kolmannen sektorin organisaatioiden tunnistamia esteitä datan hyödyntämiselle tiedolla johtamisessa. Tutkimusaineisto (n = 356) kerättiin kevään ja syksyn 2020 aikana sähköisellä lomakkeella, joka osoitettiin organisaatioiden sosiaalipalveluista vastaaville henkilöille.
Valtaosassa organisaatioista tunnistettiin yhdestä neljään tiedon hyödyntämisen estettä. Julkisissa organisaatioissa koettiin enemmän esteitä yksityisiin ja kolmannen sektorin organisaatioihin verrattuna ja suurissa organisaatioissa enemmän kuin pienissä. Tyypillisimmät tunnistetut esteet olivat puutteet osaamisessa, resursseissa ja tietojärjestelmissä. Tutkimustulosten perusteella tiedon hyödyntämisen tukea olisi perusteltua suunnata sosiaalialalla myös organisaatiotasolle valtakunnallisen ja alueellisen tuen lisäksi, jotta tiedolla johtamisen tavoitellut hyödyt toteutuisivat.

Published: November 2021

The primary goal of introducing digital information systems in healthcare organisations is to improve care processes and outcomes, however, studies that investigate the impact of digital information systems on the day-to-day operations management from the perspective of workflow and consumer satisfaction in emergency departments are scarce. Therefore, this study aimed to explore the impact of a digital clinical logistics system on the duration of patient care, consumer satisfaction and shift leaders' experience of workload in emergency departments.
A longitudinal prospective design was used. Three units participated in the study; an intervention unit, a control unit A (no implemented system) and a control unit B (system already in use). We collected data on care duration, consumer satisfaction and shift leaders' experience of workload for four weeks at five time points both before system implementation (summer 2015, spring 2016) and after system implementation (summer 2016, autumn 2016, winter 2016).
The average care duration time increased in the postimplementation period in the intervention and control B units (p < 0.001). Duration of care was higher in the intervention unit than control unit B in summer 2016 (p < 0.001) and winter 2016 (p = 0.009). Similarly, duration of care in control unit A was higher than control unit B in spring 2016 (p < 0.001). Consumer satisfaction decreased in the intervention unit, in winter 2016 (p < 0.001) and the experience of workload increased in the intervention unit, in summer 2016 and autumn 2016 (p < 0.05). However, the patients-to-nurses ratio was doubled in the intervention unit in the last time point postimplementation when compared to the first timepoint, while it remained similar in the control units throughout the study period.
This work demonstrated that a digital care logistics system may support in increasing the number of patients treated with the same nursing resources. However, this seems to connect to other outcome variables such as increased care duration, increased experience of workload and decreased consumer satisfaction in some postimplementation time points.
Seasonal and Multilevel Association Based Approach for Market Basket Analysis in Retail Supermarket
Authors: Rana S. , Mondal M. N. I.
Published: November 2021

Market Basket Analysis is an observational data mining methodology to investigate the consumer buying behavior patterns in retail Supermarket. It analyzes customer baskets and explores the relationship among products that helps retailers to design store layouts, make various strategic plans and other merchandising decisions that have a big impact on retail marketing and sales. Frequent itemsets mining is the first step for market basket analysis. The association rules mining uncovers the relationship among products by looking what products the customers frequently purchase together. In retail marketing, the transactional database consists of many itemsets that are frequent only in a particular season however not taken into consideration as frequent in general. In some cases, association rules mining at lower data level with uniform support doesn't reflect any significant pattern however there is valuable information hiding behind it. To overcome those problems, we propose a methodology for mining seasonally frequent patterns and association rules with multilevel data environments. Our main contribution is to discover the hidden seasonal itemsets and extract the seasonal associations among products in additionally with the traditional strong regular rules in transactional database that shows the superiority for making season based merchandising decisions. The dataset has been generated from the transaction slips in large supermarket of Bangladesh that discover 442 more seasonal patterns as well as 1032 seasonal association rules in additionally with the regular rules for 0.1% minimum support and 50% minimum confidence.
Indexes of Natural Selection, Migration and Reproductive Characteristics in Lutsk Population, West Ukraine
Authors: Kozak N. , Atramentova L.
Published: November 2021

In human populations natural selection is shifting to the side of prenatal development and appears as negative outcomes of pregnancies such as spontaneous abortions, ectopic pregnancies and stillbirths. Therefore, it is important to study dynamics of changes in reproductive characteristics and selection indexes of the populations in order to predict possible problems and numbers of genetic burden in the populations. Ukraine is poorly studied in this area. The aim of the study was to investigate indicators which characterize the population structure of Lutsk city, the intensity of natural selection, migration and their dynamics in two generations. 583 post-reproductive age females were anonymously questioned. Age, places of birth of the couple, the number of pregnancies and their outcomes were considered. Results show that natural selection indexes (Crow’s indexes) are decreasing from the first generation (0,26) to the second (0,20). Migration coefficients in the population of Lutsk decreased from 0.89 to 0.82 per generation and show intensive urbanization of the city for the studied time. The efficiency of the migration is low, since the biggest number of migrants come from the villages of the Volyn region (45% for first generations and 64% for the second one), or adjacent regions of Ukraine (35% and 27%, respectively). The population of Lutsk has a narrowed type of reproduction, where average number of offspring per female equal 1,86 for the first generation and 1,73 for the second generation.

Authors: Ramaroson Hans Eric , Rakotomanana René , Andriamanohisoa Hery Zo
Published: November 2021

Cosine similarity measure plays a significant role in various fields. Literature consultation confirms that the theory of cosine similarity measure has received a great interest and attention from the researchers in the world. The concept of Interval Valued Bipolar Neutrosophic Hesitant Fuzzy Sets (IVBNHFS) is recently presented and very interesting. Every element in IVBNHFS is characterized by six independent membership functions (three positive and three negative). There is no investigation on the Cosine Similarity Measure (CSM) of IVBNHFS. In this study, we firstly define a CSM and a weighted CSM between two IVBNHFS and their applications to Multi-Attribute Decision Making (MADM) process in the Interval Valued Bipolar Neutrosophic Hesitant Fuzzy (IVBNHF) setting. And, we establish some properties of CSM and a weighted CSM. We use this strategy to find out the best alternative in MADM case. Then, the new approach to clarify MADM problems in IVBNHF setting is presented in algorithmic form. And, we solve an illustrative case of MADM to demonstrate the effectiveness, workability, and appropriateness of the proposed approach. Finally, the main conclusion and future opportunity of research paper are overviewed and compiled.

This study investigates how school counsellor’s demographics influence the provision of guidance services in senior high schools in Ghana. The study was underpinned by a positivist philosophical viewpoint where a quantitative approach and the descriptive survey was used to assess how school counsellor’s demographics influence their provision of guidance services. A self-developed questionnaire was used to collect data from respondents. A total of a hundred and thirty-six (136) respondents was selected on a purposive base. The study found out that there was a significant difference between the age, gender, experience and academic qualification of counsellors have an influence in the provision of guidance services in SHSs in Ghana. The study also revealed that orientation, information and counselling services were adequately performed in SHSs, but consultation and follow-up were the least provided services. The study recommended that the Ministry of Education should ensure that the employment criteria for school counsellors should be based mostly on academic qualification and experience. Finally, the Ministry of Education and Ghana Education Service should organise seminars for school counsellors frequently to have rudimentary knowledge and skills to help them in practice.

Our old grey Subaru crept slowly up the dusty gravel road. It was a muggy evening, but you couldn’t turn the air con on or open any windows unless you wanted a car full of dust. I got to sit in the front for this last stretch to Nanny’s, so I oversaw switching out Dad's Prince Tui Teka CDs. Dad went extra slow so as not to scratch the discs, but that was hard on a gravelly road full of potholes.
Secondary Arc Extinction in Extra High Voltage Systems Using Grounding Switches
Authors: Qais M. Alias  , F. Tobia Wafaa
Published: November 2021

Long Extra High Voltage (EHV) transmission systems tend to bring a pronounced state of secondary arcing. Therefore, an essential pre-requisite for single-phase-switching application, is the possibility and speed of secondary arc final extinction during suitably short dead-time. During the past several decades, many techniques had been proposed and implemented in order to ensure fast secondary arc extinction. Among these was the use of High Speed Grounding Switches (HSGS’s). In such technique, the faulted phase is grounded via special switches; one at each end of the EHV line after the fault is cleared by both line ends circuit breakers. The primary advantage of grounding the faulted phase is the reduction of the fault point recovery voltage to a very low value. This, coupled with the circulation of opposite loop currents in the fault path, reduces the secondary arc current and lead to a fast secondary arc extinction. A sample 500kV, 300km transmission system equipped with High Speed Grounding Switches is modeled as a test system. The modified Fourier transform is used to calculate the system response through, fault, fault clearance, HSGS’s operation, and line restoration. The non-linearity of the secondary arcing state is also accounted for. The paper concludes with a presentation of some computational results related to the above mentioned EHV system showing that HSGS’s greatly improves the single-phase-switching performance.

Współcześnie konieczność ograniczania niepożądanych zjawisk i gospodarowania w sposób uwzględniający ochronę zasobów naturalnych środowiska ma szczególne znaczenie również w rozwoju rolnictwa. Wejście Polski do struktur Wspólnoty spowodowało zwiększenie możliwości zarówno wzrostu konkurencyjności i dochodowości działalności rolniczej, jak i realizacji przedsięwzięć mających przyczynić się do poprawy jakości środowiska i zachowania walorów przyrodniczych rodzimej wsi. W pracy przedstawiono wybrane zagadnienia dotyczące presji sektora rolnego wywieranej na środowisko. Zakres czasowy analizy obejmował lata 2004-2012.
Polimorfizm niełupek nagietka lekarskiego (Calendula officinalis L.) jako determinant ich wartości siewnej w warunkach laboratoryjnych
Authors: KIEŁTYKA-DADASIEWICZ ANNA , KRÓL BEATA
Published: November 2021

Badaniom laboratoryjnym poddano materiał siewny 7 odmian nagietka lekarskiego (Calendula officinalis L.): ‘Orange King’, ‘Persimmon Beauty’, ‘Promyk’, ‘Radio’, ‘Santana’, ‘Szlem’ i ‘Tokaj’. Niełupki każdej odmiany podzielono na 3 frakcje w zależności od budowy morfologicznej (typy: larwowate, skrzydełkowate, haczykowate) i określono udział wagowy każdej z nich. Określano: długość, szerokość oraz masę tysiąca niełupek poszczególnych frakcji, a także ich energię i zdolność kiełkowania. Niełupki larwowate stanowiły dominującą frakcję materiału siewnego większości odmian, u odmian ‘Szlem’ i ‘Promyk’ wartość ta sięgała 80%. Największy udział niełupek typu skrzydełkowatego odnotowano w przypadku odmiany ‘Orange King’, haczykowatego zaś u odmiany ‘Tokaj’. We wszystkich badanych odmianach nasiona typu larwowatego charakteryzowały się najmniejszą długością (4,84-5,57 mm), szerokością (1,64- 1,83 mm) oraz MTN (4,20-6,24 g). Najdłuższe były nasiona haczykowate (8,79 do 12,98 mm), najszersze zaś - skrzydełkowate (2,78-4,5 mm). Średnia masa tysiąca niełupek haczykowatych i skrzydełkowatych była zbliżona i wynosiła średnio 9,42 g. Najlepiej kiełkowały niełupki larwowate. Niniejsze wyniki mogą być inspiracją do badań nad frakcjonowaniem materiału siewnego nagietka.
Skład chemiczny bulw ziemniaka nawożonego wsiewkami międzyplonowymi w integrowanym i ekologicznym systemie produkcji
Authors: MAKAREWICZ ARTUR , PŁAZA ANNA , GĄSIOROWSKA BARBARA
Published: November 2021

W pracy przedstawiono wyniki badań z lat 2006–2009 mające na celu określenie wpływu biomasy wsiewek międzyplonowych przyoranych jesienią i pozostawionych do wiosny w formie mulczu na skład chemiczny bulw ziemniaka uprawianego w integrowanym i ekologicznym systemie produkcji. W doświadczeniu badano dwa czynniki. I – nawożenie wsiewką międzyplonową: obiekt kontrolny (bez nawożenia wsiewką międzyplonową), obornik, nostrzyk biały, nostrzyk biały + życica westerwoldzka, życica westerwoldzka, nostrzyk biały – mulcz, nostrzyk biały + życica westewoldzka – mulcz, życica westrwoldzka – mulcz. II – systemy produkcji: integrowany i ekologiczny. Bezpośrednio po zastosowaniu nawożenia wsiewkami międzyplonowymi uprawiano ziemniak na cele jadalne. W bulwach ziemniaka oznaczono zawartość suchej masy, skrobi, witaminy C oraz cukrów redukujących i sumy cukrów. Zawartość suchej masy, skrobi i witaminy C była wyższa, a zawartość cukrów redukujących i sumy cukrów niższa w bulwach ziemniaka nawożonego biomasą wsiewek międzyplonowych. Ziemniaki uprawiane w integrowanym systemie produkcji zawierały więcej suchej masy, skrobi i witaminy C, a mniej cukrów redukujących i sumy cukrów niż ziemniaki uprawiane w ekologicznym systemie produkcji. Najkorzystniejszy skład chemiczny odnotowano w bulwach ziemniaka nawożonego mieszanką nostrzyka białego z życicą westerwoldzką zarówno przyoraną jesienią, jak i pozostawioną do wiosny w formie mulczu w integrowanym systemie produkcji.
Olejki eteryczne z mięty pieprzowej i kminku jako naturalne inhibitory kiełkowania bulw ziemniaka oraz ich wpływ na cechy sensoryczne bulw po ugotowaniu
Authors: GRUDZIŃSKA MAGDALENA , CZERKO ZBIGNIEW
Published: November 2021

Celem pracy było określenie działania naturalnych inhibitorów kiełkowania na bulwy ziemniaka w czasie przechowywania oraz ich wpływ na cechy organoleptyczne ziemniaków po ugotowaniu. Materiałem doświadczalnym było pięć odmian ziemniaka przydatnych do przetwórstwa spożywczego. Ziemniaki po zbiorze umieszczono w doświadczalnej przechowalni, doprowadzając temperaturę w komorze do 8oC. W czasie przechowywania ziemniaki były zaprawiane olejkami eterycznymi z mięty pieprzowej i kminku. W badanym materiale obserwowano początek kiełkowania bulw oraz wzrost kiełków po zabiegach olejkami eterycznymi. Po przechowywaniu ziemniaki gotowano i wykonywano ocenę sensoryczną, w której uwzględniono: rozgotowanie powierzchni, konsystencję, mączystość, strukturę miąższu, smak i zapach. Wykazano, że hamowanie kiełkowania po zastosowaniu preparatu z mięty pieprzowej i kminku zależało istotnie od odmiany. Preparat z mięty pieprzowej najskuteczniej hamował kiełkowanie bulw odmiany Bursztyn (59,3% skuteczności), a z kminku bulw odmiany Stasia (60% skuteczności). Niezależnie od zastosowanego preparatu zapobiegającego kiełkowaniu bulwy odmiany Gwiazda cechowały się podobnym stanem rozgotowania powierzchni co bulwy niezaprawiane. Zastosowane naturalne inhibitory wzrostu kiełków nie zmieniły struktury miąższu oraz mączystości bulw badanych odmian ziemniaka. Zaprawianie naturalnym preparatem z mięty pieprzowej istotnie pogorszyło smak i zapach ziemniaków po ugotowaniu wszystkich ocenianych odmian.
