Fattening indicators of young rabbits when feeding Prebiolact-Kr
Authors: Tsyhanchuk O. B.
Published: December 2021

Measures to increase production are used to address the issue of providing the population with food. During the peak of the industry (1975–1985), Ukraine annually produced 120–165 thousand tons of rabbit meat, 30–45 million skins, and its share in world rabbit production reached 8 %. In the national volume of meat production, the share of highly dietary rabbit accounted for 8–10 %. Rabbit breeding in Ukraine was a very lucrative industry, which employed more than 600 thousand rabbit breeders. However, in recent years, rabbit breeding has declined due to the lack of modern scientific developments on the issues of complete feeding, rabbit keeping technology, low level of breeding and veterinary support. The development of the industry and the lack of coordinating bodies, both in the center and on the ground, are holding back. At present, the rabbit population of Ukraine is 97–98 % concentrated in individual farms and is 1.2–1.3 million breeding and repair livestock, and the rest in farms and breeding entities of various forms of ownership and management. According to the results of state certification, the breeding base of the industry in Ukraine today consists of 1 breeding plant and 7 breeding breeders of rabbit breeds. For feeding young rabbits used complete ration granular feed, the structure of which had different prebiotic content: I control group – the drug was not received, 2 experimental – 1.5, 3 – 2.0, 4 – 2.5 g/goal. per day. The studies were conducted on four groups of young rabbits, selected on the principle of groups of analogues, 25 heads in each. Thus, the total amount of feed increased from 80 g/goal. per day (35–41 days), up to 100 g (42–48 days), 120 g (49–55 days), up to 140 g (56–62 days), up to 160 g (63–69 days) up to 180 g (70–76 days). Feeding of young rabbits when reared for meat Prebiolact-Kr in animals of the second group at 43.1 g, the third 44.6 g and 45.0 g. The use of Prebiolact-Kr in the feeding of young rabbits when fed meat contributes to an increase in fattening performance, which may be the basis for the practical application of this supplement. Perebiolakt-KR showed the best results in feeding fattening and repair young animals at a dose of 2.0 g/goal per day.

The research was conducted on cattle of Black-and-White breed (Holstein and Ukrainian Black-and-White dairy breed) at LLC “Veleten” Glukhiv district of Sumy region (n = 1956) and PJSC “Breeding Plant “Stepnoy” of Kamyansko-Dniprovsk district of Zaporizhzhia region (n = 1981). Based on retrospective data analysis (“Uniform-Agri” – program of dairy herd management) for the period from 2004 to 2017 it was studied the live weight of cows in growing period (newborns, 6, 12; 18 months, at first insemination and after the first calving), body measurements of heifers (height at shoulders, chest depth, chest width, chest girth behind the shoulder blades, oblique body length, width of hips, wrist girth) and traits of reproducibility (age at first insemination, age at first calving, duration of service period, insemination index, fertility index) and milk productivity of cows (milk yields for 305 days, fat and protein content in milk for the first, second and third lactation). Based on our previously obtained data by correlation analysis method it was studied the relative variability of phenotypic traits and indicators of dairy productivity of cows. It is established that the connections of live weight of cows during their rearing with traits of milk productivity were multidirectional and ranged from slightly improbable to moderately significant values. At the same time, in both farms, the most significant highly probable connection was noted between the live weight of animals at the age of 12 months and the milk yield of first-borns that indicates the possibility of selecting heifers at the specified age to provide them future high milk productivity. There was significant variability of the relationship between body measurements and the amount of milk yield of cows for the first, second and third lactation. However, cows of both farms, had direct connection, but a bit weaker in animals at PJSC “Breeding Plant “Stepnoy”. Positive correlation coefficients between indicators of exterior and milk yields of cows give reasons to claim the efficiency of indirect selection of heifers by body measurements. Rational management of dairy farming and high profits depend a lot on knowledge of regularities of correlative variability of productive traits of cows and indicators of reproductive capacity. It is established that the connections between the traits of milk productivity and reproductive capacity of animals were different and ranged from weak to medium and from reliable to improbable. The most significant highly reliable, however, with negative correlation coefficients were observed between milk yield of cows for all studied lactations and their age at the first insemination and the first calving

Published: December 2021

Reservoirs and ponds belong to specific objects of water resources. Most reservoirs and ponds are of anthropogenic origin. They are of special importance for the Lviv region due to its terrestrial properties. In modern conditions, the importance of reservoirs and ponds is growing significantly. This is due to the fact that in many areas they form nuclei around which recreational complexes are formed. Reservoirs and ponds play an important role in the health and recreation of people. They are created by man to regulate runoff for commercial use of surface waters. The use of artificial reservoirs – reservoirs and ponds is carried out mainly depending on the water content and economic specialization of the regions. Therefore, it is very important to determine the quality of water in the ponds of Lviv region to establish ways of its further use. Recently, the problem of water enrichment with nutrients due to anthropogenic activity, which contributes to the growth of bioproducts of algae and other mass forms of aquatic organisms, has become especially acute. The article considers the rates of Lviv district of Krotoshyn village (№ 1, № 2) and Zhyrivka village (№ 3). The aim of the work was to determine the qualitative assessment of pond waters of Lviv region and the study of phytoplankton biomass and to determine the prospects for its use. The experimental part of the research was performed in the production laboratory at vul. Stryjska, 18a. The material for the research was water samples. The results of the analysis were compared with the list of maximum permissible concentrations (MPC) of harmful substances in water bodies in accordance with Order № 400 of 12.05.2010 on approval of State Sanitary Norms and Rules “Hygienic requirements for drinking water intended for human consumption” DSanPiN 2.2. 4-171-10). According to research, the water in the pond in the village of Zhyrivka turned out to be very dirty. Dirty water was in pond № 2 in the village of Krotoshin and polluted in the same village in pond № 1. The water in the ponds in the village of Krotoshin was pure in color. The water in the pond in the village of Zhyrivka was polluted, green and yellow. The highest pH level with a value of 8.8 was in the water pond in the village of Zhirivka, although it should be noted that this figure was quite high in the other two studied ponds. The lowest concentration of oxygen was in the pond in the village of Zhyrivka, the phosphate content was normal only in the water of the pond № 1 in the village of Krotoshyn. The largest amount of phytoplankton biomass was found in the village of Zhyrivka (pond № 3), which indicates pollution and “blooming” of the reservoir. This biomass can be used directly as an effective organo-mineral fertilizer.

Published: December 2021

The most common problem among ready-made foods is the adulteration of butter, which is replaced by margarine or vegetable spreads. Milk and other dairy products made from raw milk are not left out. The production and sale of low-quality, counterfeit products poses a direct threat to human health and affects the competitive environment among producers. As a result of research, it should be noted that the raw milk market is not fully saturated, so improving the quality of cream production and processing of milk products, namely butter, competition for suppliers, microbiological improvements, as well as improvements to plants and systems – remains relevant. During the analysis, some physicochemical parameters of butter were studied, namely: acidity of the fat phase, mass fraction of moisture and fat. The acidity index was within the norm, although it differed in all samples: the lowest was found in sample № 1 (1.1 °K), and the highest was in sample № 2 (1.6 °K). As for such an indicator as the content of table salt and the content of fat and pH of plasma, the oils Sweet cream “Selyanske”, 72,6 % TM “Svoya Liniya”, Sweet cream, 73.0 % LLC “Eney”, “Poltavske”, 62.5 % LLC “Techmolprom” do not meet the requirements of DSTU 4399:2005. The mass fraction of fat in butter brands PJSC “Dubnomoloko” and “Pryvat-Fud” – was lower than indicated on the package, by 1.4 % and 2.6 %, respectively, and brands “Svoya Liniya”, LLC “Eney” and Techmolprom LLC on the contrary – by 18.0 %, 18.4 % and 12.5 % more. According to the results of microbiological studies, it was found that the number of mesophilic aerobic and facultatively anaerobic microorganisms, yeasts, fungi and bacteria of the Escherichia coli group in the studied samples of butter of all brands does not exceed the permissible norms. This fact testifies to the relative “purity” of the raw material from which the butter was made, as well as to the observance of veterinary and sanitary and hygienic norms during the production and storage of butter. Summing up the research, it should be noted that, despite the identified physical and chemical shortcomings of all samples of butter, preference should be given to sour cream butter “Selyanske”, 73.0 % of PJSC “Dubnomoloko” and “Selyanske” sweet cream, 73.0 % “Privat- Fud”, as none of them exceeded such indicators as fat content and plasma pH of oil, which may indicate the absence of impurities in vegetable fats in this product.

Abstract
One of the competencies that became the main goals in the 2013 curriculum was critical thinking. All subjects, including Islamic Religious Education (PAI), should be able to deliver students to be able to think critically. However, critical thinking skills are not given much attention to PAI learning, especially Fiqh. Likewise, in the case of valuation, there are currently not many assessment instruments specifically developed to measure the ability to think in Fiqh learning. Therefore, this article intends to design a concept for assessing critical thinking skills by adopting the critical thinking test model developed by Watson and Glaser or commonly known as the Watson-Glaser Critical Thinking Appraisal (WGCTA). Two problems will be discussed in this paper, namely, how about critical thinking in Fiqh learning, and how is the concept of Critical Thinking Ability Assessment in Fiqh learning with WGCTA. The result of this paper is a sample assessment of critical thinking skills in Fiqh learning based on five indicators in the WGCTA test, namely inference, recognition of assumptions, deduction, interpretation, and evaluation of argument.
 
Abstrak
Salah satu kompetensi yang menjadi tujuan utama dalam kurikulum 2013 adalah berpikir kritis. Semua mata pelajaran, tak terkecuali PAI, hendaknya dapat mengantarkan peserta didik untuk mampu berpikir kritis. Meski demikian, kemampuan berpikir kritis tampaknya tidak banyak menjadi perhatian dalam pembelajaran PAI, khususnya fikih. Begitu pula, dalam hal penilaian, saat ini banyak instrumen penilaian yang secara khusus dikembangkan untuk mengukur kemampuan berpikir dalam bidang fikih. Oleh karena itu, artikel ini bermaksud untuk merancang sebuah konsep penilaian kemampuan berpikir kritis dengan mengadopsi model tes critical thinking yang dikembangkan oleh Watson dan Glaser atau lazim disebut dengan Watson-Glaser Critical Thinking Appraisal (WGCTA). Ada dua permasalahan yang akan dibahas dalam tulisan ini yakni, bagaimana kemampuan berpikir kritis dalam pembelajaran fikih, dan bagaimana penilaian kemampuan berpikir kritis dalam pembelajaran fikih dengan WGCTA. Hasil dari tulisan ini adalah sampel penilaian kemampuan berpikir kritis dalam fikih berdasarkan lima indikator dalam tes WGCTA yaitu penarikan kesimpulan, pengenalan asumsi, deduksi, interpretasi, dan evaluasi argumen.

Abstract
This study discusses the acceptance of the use of e-learning and games in learning Arabic during the COVID-19 pandemic. Arabic learning experienced considerable challenges in learning before the pandemic and now with the pandemic, this process has even greater challenges which ultimately require an Arabic language learning method that adapts to the generation, situation and condition of the people who are experiencing the COVID-19 pandemic so that learning can still be carried out with good and fun outcomes. This research through its five hypotheses which are built based on the Technology Acceptance Model (TAM) theory, shows that with the use of e-learning and games, a positive perception of convenience which then supports usefulness and ultimately affects the attitudes and behaviour of users in learning Arabic can be proven by the acceptance of the five the hypothesis. The consistent use of e-learning and games in learning, especially Arabic learning and the implementation of e-learning and games to support the curriculum are expected to improve student learning experiences for the better and also increase the actual use of both methods.

Published: December 2021

Emotional marketing is consistent with the trend of "product-centered" to "user-centered" marketing. In the past, marketing was more concerned about the function of products. Now, it is based on users’ emotions and humanistic care to achieve marketing purposes. According to data, more than 80% of purchases are based on emotional emotions rather than rational logic, and most purchases are triggered by emotions. Users also have different reactions to marketing information under different emotions. The emotional response degree of female customers is stronger than that of male customers in both positive and negative states. If you can sense whether the user is in a positive or negative emotional state, then consider whether to promote or not, otherwise little effect.

This paper presents the thermodynamic analysis of the cyclic steam and flue gas injection process in application to heavy oil production for Colombian oilfields in order to improve oil recovery as well as reduce the environmental impact. The process comprises two subsystems: the steam generation subsystem and flue gas compression process. Working fluid parameters were selected based on the depth of the producing wells and the experimental data provided for Colombian oilfields. As part of the thermodynamic analysis, exergy losses were calculated for the subsystems operating separately as well as together in the cyclic flue gas-steam alternating injection process. The analysis was conducted for varying ratio between the duration and steam and flue gas injection over a five-day cycle. Is was determined that the efficiency of the subsystems operating together in the process (which is achieved by minimizing the total exergy losses) is drastically different depending on whether centralized power or local power generation is used for energy supply. It was concluded that an economic analysis is required in addition to the thermodynamic analysis. The varying part of the relative costs for the cyclic steam-flue gas injection process was assessed and it was shown that the optimal solution would be steam-flue gas injection with an injection ratio of 4.5:0.5 (for a five-day cycle) that uses a centralized power source.

Authors:   Oil and Gas Research Institute RAS, Svalov A. M.
Published: December 2021

Analytical solutions of one-dimensional equations of poroelasticity, describing the stress distribution in the depression (repression) funnel, are obtained in this work. It is shown that the influence of the boundary conditions on the wellbore wall is significant only in a relatively small (~1 m) vicinity of the wellbore bottom zone. It has been established also that in fractured rocks in cased wells, the compressive angular stresses, which largely determine the filtration conductivity of the bottomhole zones, will be less than in uncased wells. A method is described that makes it possible to increase the tightness of preserved wells in depleted fields. The method consists in cutting out a section of the casing pipe above the productive formation, expanding the wellbore in this section, installing a spring metal centralizer in this section, followed by cementing it. The formation of such a rigid element associated with the casing will prevent rock displacement relative to this pipe and ensure the tightness of the near-wellbore zone of the well.

The change in sensitivity to viral infection of cultures of three species of Black Sea microalgae (Tetraselmis viridis, Dunaliella viridis and Phaeodactylum tricornutum) after exposure to a constant unidirectional magnetic field with a magnetic induction of 600 G is experimentally studied. The studies were carried out with using a developed laboratory installation. With the duration of the experiments 24 h and 48 h, it was recorded that being in a magnetic field resulted in an increase in the resistance to viral lysis in microalgae T. viridis, its decrease in P. tricornutum and no changes in D. viridis. We assume that the revealed changes in the sensitivity of microalgae to viral infection after exposure to a magnetic field are due to their species characteristics and selectivity.

The purpose of this work is to identify individual cases of the occurrence of a critical layer in the system of zonal currents of the Indian Ocean within certain months for the period 1979-2018 aimed at studying the impact of instability of these currents on the Indian Ocean Dipole (IOD) generation. It has been shown that in most cases, the critical layer occurrence coincides with the onset of positive IOD events and takes place one or two months before the onset of these events. This indicates that sporadic instability of the system of zonal currents is one of the main mechanisms for generating IOD events in the region.

The use of water for various human needs can be considered as an anthropogenic factor affecting water resources. The amount of water consumption is determined by the size of the population, the level of development and the state of housing and communal services, climatic conditions and other factors. The agricultural sector plays a significant role in the economy of the South and North Caucasian Federal Districts. The increase in agricultural production, especially in the southern drylands, is largely due to its reliable and high-quality water supply. A large share of the agricultural sector in the structure of water use determines that the water turnover coefficient in the region as a whole is much lower than the national one. The analysis of open sources revealed the key problems of water consumption in the region and enabled to identify specific measures for revising its structure.

A model of a cloud-based system for processing environmental monitoring data is proposed. The model takes into account the multi-tier web applications and the heterogeneity of the input flow of applications. As a characteristic of the efficiency of the data processing system, an additive criterion is chosen that takes into account the volume of processed requests and the load on the resources of the cloud infrastructure. The approach under consideration will allow creating a basis for modeling the processes occurring in natural-technical systems (NTS), analyze data processing processes during monitoring of key performance indicators of NТS and ensure that these indicators meet the requirements specified in SLA agreements through the use of alternative data processing strategies.

Developing forward-looking and advanced information systems requires the creation of a unified architecture, with unified hardware and software based on comprehensive integration of components of natural and technical information systems not only at the technical, but also at the functional level, The implementation of the above structure leads to a multiple increase in the volume of calculations on large-bit data arrays carried out in real time, as well as to the complexity of computational algorithms. It results in sharp contradictions between hardware costs, speed, accuracy and fault tolerance. The work is concerned with the formation of a methodology for the probabilistic representation and information transformation and the development on its basis of techniques, methods and algorithms for the synthesis of computing devices and components for advanced and existing information systems built on the domestic element base, which becomes an effective and high-tech means of overcoming these contradictions.

Eco-biological expedition research involves the collection of biotic and abiotic material (samples), which is attached to spatio-temporal location. Researchers often use the geographical name of the place instead of the geographical coordinates to indicate the spatial location of a sample. For this reason, an expedition information system must support work with geographical names. The article describes the structure of the expedition database, where the main emphasis is made on geographical names. A method of presenting the official and unofficial names of land and water bodies in a single table is proposed. This way of presenting geographic information makes working with the information system more people-friendly.

Świadomość funkcjonowania green bonds na polskim rynku obligacji korporacyjnych
Authors: Gemra Kamil
Published: December 2021

Inwestycje związane ze zrównoważonym rozwojem zazwyczaj mają charakter długoterminowy. Zapewnienie odpowiedniego kapitału jest niezbędne, aby móc je realizować. Jednym z ciekawych instrumentów finansowych, zdolnych do sprostania tym oczekiwaniom, są tzw. zielone obligacje (green bonds). Pierwsza zielona obligacja została nazwana „obligacją klimatyczną” i została wyemitowana przez Europejski Bank Inwestycyjny (EBI) w 2007 roku. Od tego momentu rynek ten zaczął się rozwijać, a Polska ma istotny wkład w jego rozwój, ponieważ stała się pierwszym krajem, który wyemitował zielone obligacje państwowe w grudniu 2016 r. Celem artykułu jest zbadanie świadomości funkcjonowania oraz planów dotyczących green bonds wśród emitentów obligacji, którzy wprowadzili do obrotu giełdowego na rynku Catalyst tradycyjne obligacje korporacyjne. Cel ten został osiągnięty za pomocą badania ankietowego emitentów obligacji notowanych na rynku Catalyst. Analiza wskazała, że emitenci coraz częściej spotykają się z zagadnieniem ESG i chcą wdrażać jego założenia do swojej strategii rozwoju, a dodatkowo, większość ankietowanych w przyszłości będzie chciała wyemitować zielone obligacje, co może spopularyzować ten instrument finansowy.

Uszczelnianie podatku od towarów i usług z perspektywy podatnika
Authors: Bełdzikowski Marek
Published: December 2021

Koszty ponoszone przez podatników w wyniku „uszczelniania” podatku od towarów i usług pozostają w cieniu badań nad wzrostem wpływu z podatku VAT. Skala zmian w podatku od towarów i usług, szczególnie po 2015 roku, w sposób bezprecedensowy wpłynęła na sytuację podatników. Znalazło to odbicie w szeregu oficjalnych dokumentach, takich jak np. oceny skutków regulacji projektów aktów prawnych czy analizach przygotowywanych przez organizacje międzynarodowe. Pozwala to sięgnąć po efekty prac organizacji międzynarodowych w tym zakresie i dokonać unikalnego porównania Polski z innymi krajami. Umożliwia to postawienie celu badawczego polegającego na ustaleniu wpływu „uszczelniania podatku” na koszty tego procesu ponoszone przez podatników. Dla jego realizacji posłużono się analizą opracowań i danych statystycznych. Wydają się one jednoznacznie wskazywać na pogorszenie się środowiska regulacyjnego dla podatników VAT w Polsce, co wskazuje na wyraźny wzrost kosztów poboru podatku VAT dla jego płatników.

Stabilność makroekonomiczna Unii Europejskiej oraz państw członkowskich w latach 2010-2019
Authors: Kulbacki Michał
Published: December 2021

Celem artykułu jest analiza stabilności makroekonomicznej gospodarek UE- 27 przy wykorzystaniu metody PSM. Jak wynika z przeprowadzanych badań, w dekadzie przed wybuchem pandemii COVID-19, stabilność makroekonomiczna krajów Unii Europejskiej w średnim okresie wyraźnie wzrosła, z wyjątkiem Szwecji. Analizy dla poszczególnych gospodarek pokazują, że większości z nich udało się dokonać poprawy, zarówno w obszarze stabilności wewnętrznej jak i zewnętrznej. Otwarte pozostaje pytanie, czy poprawa stabilności mogłaby być bardziej znacząca, gdyby polityka makroekonomiczna w większym stopniu była skoncentrowana na zmniejszeniu bezrobocia oraz przyspieszeniu wzrostu gospodarczego, a w mniejszym stopniu na poprawie salda deficytu budżetowego. Przeprowadzone badania wskazują, że poprawa sytuacji makroekonomicznej będzie długotrwałym procesem, w ramach którego polityka gospodarcza powinna stawiać sobie za cel dążenie do równomiernej poprawy wszystkich tworzących ją czynników.

Authors: Marzec Patrycja , Braun Jan
Published: December 2021

Przedmiotem badań w niniejszym opracowaniu jest aspekt finansowania działalności startupów pod względem źródeł pozyskiwania kapitału. Analizie poddano dostępne dla startupów zewnętrzne źródła finansowania pochodzące ze środków publicznych. Celem opracowania jest identyfikacja najczęściej wykorzystywanych źródeł finansowania działalności startupów oraz ocena, jaką rolę odgrywają dostępne środki publiczne na tle pozostałych występujących źródeł. Artykuł powstał w oparciu o przegląd literatury przedmiotu. Na tej podstawie dokonano charakterystyki specyfiki funkcjonowania startupów oraz zidentyfikowano dostępne źródła finansowania ich działalności w poszczególnych fazach rozwoju. Zastosowano także analizę danych zastanych, pochodzących z raportów Fundacji Startup Poland oraz raportu European Startup Monitor, pod kątem znaczenia środków publicznych w finansowaniu działalności startupów. Z przeprowadzonych badań wynika, że w ostatnich latach coraz popularniejsze staje się w Polsce dofinansowanie działalności startupów z wykorzystaniem Polskiej Agencji Rozwoju Przedsiębiorczości oraz Narodowego Centrum Badań i Rozwoju. Biorąc pod uwagę aspekt pozyskiwania dofinansowania z grantów ze środków publicznych przez startupy, należy zauważyć duży odsetek aplikujących podmiotów, które nie otrzymują wsparcia ze strony państwa. Trzeba jednak podkreślić, że środki publiczne odgrywają kluczową rolę w strukturze zewnętrznych źródeł finansowania tak w polskich, jak i w europejskich startupach.

A CONSTRUCTIVIST APPROACH TO INTEGRATED SCIENCE EDUCATION: TEACHING PROSPECTIVE TEACHERS TO DO SCIENCE
Authors: Lamanauskas Vincentas
Published: December 2021

Learner-centered approaches to teaching and schooling require supportive policies for preparing effective educators. Moving from constructivist philosophy, psychology and epistemology to the characterization of constructivist teaching and learning environments presents a challenge. Constructivist philosophy does not dictate how one should teach; however, it does make it incumbent upon the teacher to deal with each learner as an individual, to value diversity of perspective, and to recognize that the learner's behavior is a direct reflection of his / her life experiences. Bandura (1977, 1986, 1995, 1997), Fullan (1993), and other self-efficacy researchers have concluded that the catalyst for educational reform is the individual teacher and that a teacher's behaviors, values, beliefs, and ambition to act may be enhanced or suppressed during student teaching.
