Published: December 2022

Purpose. Substantiation of the stress-strain parameters of a rock mass state to identify potential mine methane accumulation in the roof rocks of the extraction pillar. Methodology. Characterization of stratification cavity in rock mass for mine methane extraction relied upon analytical studies. The research is based on a method by Professor O.V. Savostyanov to calculate a stress-strain state of rocks. The method has been implemented in GeoDenamics Lite software. The use of the method helps obtain both geometrical and physical parameters of load characteristics for typical rock layers from the coal seam up to the surface. The abovementioned makes it possible to identify areas of rock stratification, coal bench being flaked away, and the number of rock layers after stratification. Mining and geological conditions of the coal seam occurrence and mining technology are the output data for the research. Findings. Analysis of geometrical and physical parameters of load characteristics on the roof rocks of a coal seam has supported the fact that abnormal pressure areas propagate within the rock mass. The listed parameters vary from a seam up to the surface normally both towards the rock mass and towards the mined-out area along with the stope advance. The abovementioned helps define parameters of stratification cavity formation within the roof rocks of an extraction pillar since the cavities may accumulate mine methane. Originality. Dependencies of the changes in rock layer subsidence height have been derived based upon formation dynamics of the mined-out longwall volume. Regularities of changes in volumes of rock formation stratification cavities have been identified depending upon the strength and thickness of the rock layers; closeness to mining area; and stope advance velocity as well as its length. Practical value. Based upon the method by Professor O.V.Savostyanov, an algorithm has been proposed to define possible mine methane accumulations after mining operations within the extraction pillar are completed. Hence, the areas of methane accumulation will be considered in future as extra sources of fuel material. At the same time, it has been proposed to complement operation mode of a mining enterprise with biogas plants if the produced mine mixture is poor. A technological scheme for the combined mine methane-biogas extraction has been provided.

Purpose. To experimentally determine the main design and operational parameters of the influence of rock mass properties on the Roller Crusher performance when processing basalt rock mass. Methodology. The crushing and grinding of basalts are studied by the methods of mathematical statistics in order to identify the results obtained and determine the dependences of technological parameters on the mechanical impact factors. Experimental studies are carried out on the example of basalts from the Rafalivskyi quarry in the Rivne region. Findings. It has been revealed that the elemental composition of rocks in the benches of basalt quarries has a different mineral composition. Experimental studies of the rock crushing results have determined the efficiency of using screening for crushing basalts. The experimental dependences of the roller crusher performance in crushing and grinding modes on the properties of the rock mass have been obtained. Originality. The value of crushed rock fractal joints has been found, when using cone and centrifugal crushers, which is characterized by the shape factor and fractal dimension D. For cone crusher Kf=2.15.0 and D=1.4. For centrifugal crusher Kf=1.51.8 and D=1.17. These parameters testify to the energy feasibility of using centrifugal crushers. The high value of the multiple correlation coefficients R2 and Fisher criterion F, whose value at a significance level of 0.05 is higher than the critical one, indicates a sufficient convergence between the experimental and theoretical results and the accuracy of the obtained analytical dependences. Practical value. The generalized models for determining the Roller Crusher performance, obtained for each rock type, based on significant factors, greatly facilitate the choice of parameters for crushing and grinding processes, and also allow choosing a rational mode of crusher operation.

Authors: Bialobrzheskyi O , Nozhenko V , Todorov O
Published: December 2022

Purpose. To identify the vibration power components caused by misalignment of electrical machine shafts in the instantaneous power of the induction motor. Methodology. The power components of the induction motor are analytically determined taking into account the power caused by torque vibrations on the shaft. Based on this, using the methods of mathematical modelling in the visual programming environment, the known model of a three-phase induction motor with a short-circuited rotor has been made. In addition, elements and connections are introduced which realize the formation of the moment caused by the imbalance of rotating masses. Using Fourier transform of the electric power of the induction motor, we determine its discrete spectrum. Experimental research is conducted on the electric power of the induction motor with a short-circuited rotor, in similar model conditions, on laboratory equipment. With the use of a virtual device synthesized in the LabVIEW package, the wavelet analysis of stator electric power of the motor of laboratory electrotechnical complex is performed. Findings. Differential equations of the induction motor with a short-circuited rotor in abc coordinate system are obtained, which reflect the distribution of instantaneous power in the machine taking into account the vibration moment. As a result of modelling according to the specified equations of the induction machine, in the conditions of full symmetry of parameters of the scheme and the mode with eccentricity of rotating masses, low-frequency vibrations of electric power of a stator with frequency of 25 Hz have been found. Similar results were obtained as a result of wavelet analysis of the electric power of an induction motor of a laboratory electrotechnical complex. Originality. Rationality of use of instantaneous electrical power of induction motor stator for detection of vibration caused by misalignment between its shaft and the shaft of another machine has been substantiated, which allows detecting vibration without complex methods of measuring vibration displacement and its derivatives. Practical value. Detecting vibration by measuring the electrical parameters of the stator circuit of the induction motor and determining the vibrations of its instantaneous power without the use of specialized equipment significantly simplify the procedure of vibration diagnostics at its early stages.

Purpose. To develop an algorithm for choosing alternative routes with dynamic changes in the risks of cargo transportation. To propose a structure of the management system of logistics departments and an enterprise in general to neutralize risks. Methodology. The method of mathematical formalization was used to form a mathematical model of management of transportation routes with changes in threats in real time; the method of a system approach to the enterprises business processes was used to take into account their impact on logistics processes; risk stratification method for evaluating the efficiency of logistics operations; the method of using the matrix of vectors made it possible to form a mathematical approach to solving a dynamic logistic problem and to considering it as a time-dispersed system; the method for dividing parameters by measurement scales allowed using a unified mathematical approach to the formalization of the problem; the method of sequential approximation made it possible to choose the most acceptable options for making management decisions. Findings. It is established that the level of risks can change from minimal to unacceptable in real time, which proves the importance of assessing both the degree of risk and the rate of its change. An approach is proposed to coordinate the proposed alternative routes, taking into account the requirements of various structural departments, achieving both risk reduction, and ranking of goals, ensuring less time for transportation. The formation of a decision tree on logistics chains and continuous monitoring of risks is substantiated. Originality. An algorithm for selecting alternative routes with dynamic changes in cargo transportation risks is developed. Astructure of the management system for logistics departments and enterprises to neutralize risks is proposed. Practical value. The proposed approach makes it possible to predict risks in the face of their dynamic changes and to ensure their effective management.

Published: December 2022

Various factors have been reported that affect the growth performance of layers, such as genetics, nutrition, environment, and disease. Attaining appropriate growth is essential to ensure profit. The present study was conducted to make comparative analyses of the growth performance of four commonly available layer strains in Bangladesh. A total number of 400-layer day-old chicks (DOCs), 100 from each of NOVOgen brown, ISA brown, Hy-Line brown and Bovans brown were used for the experiment. The birds were equally divided and randomly assigned to 4 treatments having 4 replications in each treatment comprising 25 birds per replication. All birds fed diet with similar composition and provided with the identical care and management up to 16 weeks of age. The results from this study revealed that there were no significant differences among the growth performances (weekly body weight, feed intake, uniformity and survivability) of four commonly available layer strains and all the strains followed the standard very closely. There were also no statistical differences based on the economic parameters of the strains compared in this study. Taken together, it may be concluded that the layer strains available in Bangladesh are highly competitive and suitable for local climatic conditions and the farmers can rely any of them.

Published: December 2022

Reproductive anatomy is vital for successful reproductive management and has significance for application of assisted reproductive biotechnology. This study was carried out to characterize biometrically and histologically reproductive organs of 50 slaughtered female cattle (<3 years; n=25, 3 to ≤5 years; n=25). The measurements (length, weight and width) of the right segment of the studied reproductive organs were greater compared to the left segment. No significant difference (p>0.05) was observed between left and right ovary length, width and weight within and between age groups. The length of ovaries were 1.92±0.19 cm and 1.95±0.04 cm at <3 years; 2.16±0.21 cm and 2.17±0.19 cm at 3 to ≤5 years; width were 1.09±0.14 cm and 1.17±0.10 cm at <3 years and 1.31±0.10 cm and 1.46±0.11 cm at 3 to ≤5 years and the weight were 1.77±0.41 gm and 2.20±0.57 gm at <3 years; 1.79±0.45 gm and 2.54±0.14 gm at 3 to ≤5 years in the left and right ovaries, respectively. Oviduct length, width and weight did not differ significantly (p>0.05) between the left and right oviducts within and between the age groups. Oviduct length (16.36±0.78 and 17.58±0.97 cm), width (0.21±0.02 and 0.26±0.33 cm) and weight (0.72±0.03 and 0.81±0.11 gm) was found for the right oviduct at <3 years and 3 to ≤5 years and for left oviduct length, width and weight were 16.20±0.65 and 16.64±0.86 cm; 0.19±0.02 and 0.23±0.03 cm; and 0.69±0.04 and 0.79±0.13 gm, at <3 years and 3 to ≤5 years, respectively. However, uterine horn length differed significantly (p<0.05) between age groups in the left (16.18±1.18 vs 27.45±2.98 cm) and the right horn of the uterus (17.45±1.40 cm vs 28.35±2.88 cm). On the other hand, uterine horn width and weight were not differed significantly between the left and right segments within and between the age groups. Uterus body length and weight were significantly (p<0.05) higher at 3 to ≤5 years compared to <3 years old cow. The average weight, length and width of uterine body were 44.40±7.33 gm vs 21.49±5.91 gm; 7.89±0.61 cm vs 5.87±0.43 cm; 3.46±0.27 cm vs 2.76±0.34 cm at <3 years and 3 to ≤5 years, respectively The whole uterus weight was also differed significantly (p<0.05) at <3 years (47.18±14.92 gm) and 3 to ≤5 years (86.07±11.98 gm). Histological studies showed ideal characteristics of cattle oviduct and uterus. In nutshell, the right ovary was larger in length, wider in diameter, and heavier in weight as compared to left one in indigenous cattle of Bangladesh.

A Study on Shield Design Aspects of a Semi-Industrial Co-60 Gamma Irradiation Facility at Gamma Source Division of Institute of Food and Radiation Biology of the Bangladesh Atomic Energy Commission
Authors: Ahmed S , Khan MJH , Nahar A , Mortuza MF , Hosan MI
Published: December 2022

The aim of this work is to investigate the existing shield design aspects of a semi-industrial Cobalt- 60 Gamma Irradiation Facility for 100 kCi, designed for irradiation of pharmaceutical products and daily foodstuffs as well as for research and development purposes at the Institute of Food and Radiation Biology (IFRB) of the Bangladesh Atomic Energy Commission. Earlier, the initial activity of this facility was 65 kCi and stone based reinforced concrete (SBRC) of density 2.60 g/cc and specific thicknesses were used to shield the facility for safety to operational personnel and outside public. Due to a large demand for irradiation of pharmaceutical products as well as of daily foodstuffs, IFRB has decided to increase the initial activity up to 100 kCi for this facility. For this reason, the shielding design aspects of this facility were needed to be recalculated and checked for safety. This analysis was done using the Point-kernel Shielding Code Micro-Shield 5.05 and public domain Point-kernel Shielding code QAD-CGGP2 respectively considering the radiation worker dose limit of 10 μSv/hr of the International Commission on Radiological Protection, ICRP-60, 1990. The corresponding dose limit for public at large is 0.5 μSv/hr. The calculated dose rates at different locations around the facility are far below 10 μSv/hr except in one area. This location is inside the source room. No one is allowed to enter the room when the facility is in the ON mode. However, except one location, positions outside the facility have dose rates about 3 time higher than 0.5 μSv/hr, the dose limit for public at large. Therefore, this analysis shows that the existing shield design aspects of IFRB’s Co-60 gamma source room is safe for a 100 kCi source from the viewpoint of radiation safety to operating personnel but not for public at large within proximity of the facility.

Published: December 2022

This research was conducted with the aim to detect schizophrenia automatically from EEG signals using machine learning algorithms. The 16 electrode EEG data were collected from the online repository where 43 schizophrenic and 39 healthy persons’ dataset is available. By applying Low Pass Filter and Total Variation Denoising method, raw EEG signals were denoised and were decomposed into beta, alpha, theta and delta waves by using Dual Tree Complex Wavelet Transform. To apply machine learning algorithms, five features: mean, median, standard deviation, energy and kurtosis were considered for all the four wave bands. With Linear Support Vector Machine and Random Forest classifier machine learning algorithms, 12 out of 16 channels were classified with test accuracy above 95% and F1 score above 90%. Among them, 7 channels were predicted with 100% test accuracy. This research thus has the potential to detect schizophrenia unsupervised and within a noticeably short period of time giving the opportunity to real time monitoring of patients. Hence, people living in remote areas or deprived of adequate healthcare professionals can be benefitted through the outcome of this research.

Strategic Perturb and Observe Algorithm for Partial Shading Conditions
Authors: Awan Muhammad Mateen Afzal
Published: December 2022

Solar photovoltaic (PV) is the cheapest renewable resource of electrical energy. Its dependence on the connected load bounds its production capability. To deliver the determined power, it is required to operate at the maximum power point (MPP) in the characteristic curve of the PV array. Tracking the MPP requires electronic circuits govern by MPP tracking (MPPT) algorithms. The most simple, cheap, and softly implementable MPPT algorithm is “Perturb and Observe (P&O)”. It efficiently performs under uniform weather conditions (UWC) but fails under partial shading conditions (PSC) due to the formation of multiple peaks in the P-V characteristic curve of a PV cell. In this paper, weaknesses of the P&O algorithm are studied and overcome by structural modifications. The proposed structure is named the “strategic P&O algorithm”. Performance of the conventional and proposed algorithms is evaluated at the following standard benchmarks, tracking speed, tracking time, efficiency, and ability to track the GMPP under PSC. Results have shown that the proposed SP&O algorithm has outperformed the conventional P&O algorithm under numerous weather conditions. Simulations are performed in MATLAB/Simulink.
Technological Innovation and Environment Degradation in South Asian Countries
Authors: Ayesha Naz  , Muhammad Ejaz
Published: December 2022

This study is an attempt to analyze the impact of technological innovations on Environmental Degradation (ED) in selected South Asian countries over the period 1996 to 2019. The limited and inconclusive result on the association between technological innovation and the environment particularly in South Asia provides an impetus to explicitly reexamine this relationship. The current study is unique in using various greenhouse gases to measure environmental degradation. Moreover, technology is also bifurcated into all other technological innovations and environment-related technology (eco-innovation). Panel robust least square is used to obtain the results. The outcome shows that technological innovations and GDP is contributing to CO2 emissions. It means that these two variables have an unfavorable influence on the environment. However, eco-innovations appeared to be significant in reducing CO2 emissions and other greenhouse gases. Hence, eco-innovations are desirable to lessen the negative consequences on the environment. Low carbon technologies redefine the production and consumption pattern to offset the environmental damaging trend. Carbon emission rates critically depend on the future direction of technological innovations, hence, this study suggests increasing the degree of eco-innovations to protect the environment.
OUN AND UIA DOCUMENTS ON THE CIVILIAN POPULATION RESISTANCE FORMS AND METHODS DURING THE ELECTIONS TO THE SUPREME COUNCILS OF THE USSR, AND LOCAL AUTHORITIES IN THE POST-WAR PERIOD USSR
Authors: STASІUK Oleksandra
Published: December 2022

Based on the analysis of Organization of Ukrainian Nationalists (OUN) and Ukrainian Insurgent Army (UIA) documents, the scale, forms, and methods of the civilian population resistance of the western Ukrainian regions to the Soviet election campaigns in the postwar period are shown. It is noted that most of the OUN and UIA documents, which systematically cover the elections to the UkrianeSSR, USSR Supreme Soviets, and local authorities in western Ukraine, are stored in the Sectoral State Archives of the Security Service of Ukraine. It is investigated that the most informative of them are the reports of OUN leaders at various levels, which carefully record each preparation stage and elections conduction under the government supervision actions and reactions, which allows the author to recreate a holistic government picture, efficiency, and emotional assessments.

It is emphasized that the insurgent reports testify to the mass and general regional protests dimension and outline the reasons that forced Western Ukrainians to protest. As researched, the Western Ukrainian protest position was motivated by political, economic, socio-domestic, as well as moral, and psychological reasons, but political ones remained a priority. It was found that the protests were socially differentiated: the peasantry protested most actively, the workers and intellectuals joined the situation, and women's anti-government protests (both individual and mass), outnumbered men's in number and emotional tension. The civilian population in opposition to the authorities used mainly non-violent forms and resistance methods, which were divided into the mass, group, and individual, overt and covert, aggressive and demonstrative, etc.; widely used and non-traditional.

Statistical data from the reports of OUN leaders at various levels concerning the voting results in the elections to the Ukraine SSR and the USSR Supreme Soviets in 1946-1947 and the election falsification facts results by government officials were analyzed. It is emphasized that these figures confirm the mass western Ukrainian region's population resistance to the planting of Soviet-style democracy in the region and contrast with the official reporting. It is noted that the insurgent reporting, although not devoid of political connotations, covers the processes much more objectively than the Soviet party documents.
THE HUNGARIAN REVOLUTION OF 1956 IN THE KGB DOCUMENTS: THE CASE OF TWO ARCHIVES
Authors: VARADI Natalia
Published: December 2022

The article deals with the general analysis of documents on the history of the 1956 Hungarian Revolution, which are in the Sectoral State Archive of the Security Service of Ukraine and the State Archive of Transcarpathian Oblast. It is the first attempt to show the documents about the deportation of Hungarian citizens to the Soviet Union and to present the reactions of the local Transcarpathian Hungarian nation to the events of the 1956 Hungarian Revolution, and it also highlights the actions of the authorities that were aimed at the purposeful total ideological control and thus influenced the formation of the general public’s opinion about the surrounding events.

The main aim of the study is to show the deportations of the Hungarian revolutionists to the Soviet Union in 1956 through archival documents and to introduce the political leaflet distributor groups in Transcarpathia, which were formed during the Hungarian war of independence in 1956.

There are archival documents containing different data about the behavior of the Hungarian population in Transcarpathia related to the Hungarian events. The documents also provide information about the punishments that concerned the Hungarian groups engaged in politics. These documents reveal that the political general headquarters in Uzhhorod had been operating for a long time after Hungary was invaded by the command of Moscow.

It is possible to argue that the process of exploring the sources relating to the retaliation after the revolution of 1956 has not been finished yet, there are still hundreds of archival documents, mainly in Ukraine and in the former Soviet Union Archives, which still need to be explored. However, besides getting to know the real facts of the history of the Revolution in 1956, it is important to perceive that, despite the oppression, there were people in Transcarpathia too, who dared to be brave, to believe, and protest. And there were ones who paid with their lives for justice. Because of participating in the revolution, many people were arrested, sentenced, imprisoned, deported, and executed. Their truth and role should be clarified.
«HE WAS NOT A CORRUPT PERSON» (sketches to a political portrait of Marian Melenevskyi)
Authors: PATER Ivan
Published: December 2022

The paper scrutinizes the beginning of Marian Melenevskyi's revolutionary activities, his participation in student movements, peasant strikes, founding the organization of rural workers, and the distribution of campaign pieces among the peasants with a call to defend their economic rights, for which he was exiled. His close cooperation with the Ukrainian Socialist Party, its material support, and recognition of the program are stressed, as well as his quite significant financing of the Revolutionary Ukrainian Party and enthusiastic activity in its Foreign Committee. Differences between the political emigrants-erupists and the Central Committee of the RUP in Naddniprianshchyna region on the issue of the party's status are pointed out: regarding unification with the Russian Social Democratic Workers' Party (RSDWP) or preserving the organization's full party independence.

The negation by M. Melenevskyi's group of the national principle in the Ukrainian labor movement and slogans of the autonomy of Ukraine led to the split of the RUP into two organizations – the Ukrainian Social Democratic Union and the Ukrainian Social Democratic Labor Party. Emphasis is placed on the merging of the Union with the RSDWP, its transition to the class struggle basis, neglecting a national factor by members of the Union, and non-recognition of Ukraine's independence postulate. Additionally, there are noted the Union's activities success during the elections to the II State Duma in 1907, and its defeat during the reaction to provocateurs' denunciation, the arrest of its members, Melenevskyi's unsuccessful attempt to revive the organization's activities abroad and in Ukraine.

Dynamic activities of Melenevskyi in the Union for the Liberation of Ukraine (ULU), created with the outbreak of World War I, are revealed. The author stresses Melenevskyi's co-authorship of ULU's appeals to the European peoples, conducting extensive information and diplomatic work in the Black Sea-Balkan region, in particular in Turkey, in an attempt to use it as a springboard for Ukrainian insurgent actions on the Black Sea coast, his cooperation with Turkish government factors and the recognition of independent state aspirations of Ukrainians.

A negative attitude of the Russian social democrats to Melenevskyi's state ideas is shown, and his focus only on his national forces in achieving the state independence of Ukraine is highlighted. While welcoming the February revolution in Russia, he hoped for the total liberation of the Ukrainian people from Moscow despotism and refused to participate in the work of the Hetman's government. His diplomatic activities and work in various Soviet trade and cooperative offices in London are highlighted. To sum up, the unreasonableness of the first and second arrests of M. Melenevskyi and the shooting execution sentence handed down by the relevant judicial authorities of the USSR are shown.

KYRYLO STUDYNSKYI'S MEMORIES OF THE STRUGGLE FOR THE UKRAINIAN UNIVERSITY IN LVIV AT THE BEGINNING OF THE 20th CENTURY
Authors: MYSAK Nataliia
Published: December 2022

The source study highlights one of the aspects of the Ukrainians' struggle for the opening of a national higher school in Halychyna at the beginning of the 20th century, in particular the events of January 23, 1907, as a result of which more than a hundred students were arrested. The published memoirs of Lviv University professor Kyrylo Studynskyi are an invaluable source for understanding the public attitude to the problem of the Ukrainian university in Lviv. The positions of the teaching staff, the administration of the educational institution, and some representatives of the regional organization are analyzed. Indicated differences in the views of Ukrainian professors – from non-acceptance and ignoring to a clear awareness of the need to continue the struggle. Special attention is focused on the clear position of K. Studynskyi and O. Kolessa, who, despite personal misunderstandings, came to the defense of the students. Based on the analysis of the general meetings of the Lviv University teaching staff, discussions and verbal altercations, it is revealed the negative influence of the chauvinist-tinged rhetoric of the contemporary press on the formation of prejudiced views of the majority of Polish teachers towards Ukrainian youth. The reluctance of those who influenced the formation of students' identity and worldview to understand the nature and motivation of their protest actions and deeds is also indicated. At the same time highlighted the wait-and-see position of the regional administration on this issue.

The publication reveals the author’s position, particularly his emotional states, experiences during speeches and conversations with teachers, court officials, representatives of authorities, concern for the fate of youth, and active participation in supporting arrested students. Reproduced a detailed chronology of events in which K. Studynskyi participated: the general professors meeting of the Lviv University, the arrests of Ukrainian youth, their detention in a pre-trial prison, the discussion of the consequences of student riots at a meeting of the Regional School Council, a personal audience with the Governor, etc. The formation of the reputation of K. Studynskyi as a sincere supporter of Ukrainian students in the youth environment is shown.

«“SOKIL-BATKO” REALLY HAS ENOUGH OF VARIOUS WORRIES ALREADY». FROM THE UNKNOWN CORRESPONDENCE BETWEEN IVAN BOBERSKYI AND THE MANAGEMENT OF THE SOKIL-BATKO SOCIETY IN LVIV
Authors: SOVA Andrii
Published: December 2022

The huge epistolary heritage of a socio-cultural and military-political figure Prof. Ivan Boberskyi has not become the subject of a separate study in Ukrainian science. The author presents 12 letters, which are stored in fund 312 «Ukrainian sports society “Sokil-Batko”, Lviv» of the Central State Historical Archive of Ukraine in Lviv. Dated back to 1937, they highlight I. Boberskyi's relationship with the leadership of the «Sokil-Batko» Ukrainian society in Lviv. Based on them, it was revealed, what kind of efforts I. Boberskyi was made in the diaspora and Halychyna for raising funds for the Sokil movement activities, in particular, for the arrangement of a «Sokil-Batko» square for exercising «Ukrainian City» («Ukrainskyi Horod») in Lviv. The letters also provide information on the professor's editorial work, for instance, regarding the second edition of Edvard Zharskyi's «Osnovy Sokilstva».

Investigated that the letters contain information about the plans of the Ukrainian society in Halychyna, in particular, about preparing the 4th Regional Movement, which was to take place in Lviv in 1938, including new types of sports, etc. In I. Boberskyi's letter to Sokil-Batko from September 10, 1937, the author found his analytical article entitled «Hartovana Stal» published with insignificant changes in the Sokil calendar for 1938.

As stated, the presented epistolary heritage of the 1930s is part of an interesting and unique correspondence that sheds light on the life path of I. Boberskyi and on many events of the Ukrainian history of an interwar period.

LEGAL STATUS OF THE UKRAINIAN LANGUAGE IN THE LOCAL GOVERNMENT BODIES OF INTERWAR HALYCHYNA
Authors: RUDA Oksana
Published: December 2022

The study investigates interwar Poland language legislation, which regulated the legal status of the Ukrainian language in local government bodies of Halychyna. The legal status of the Ukrainian language in the region was determined by the Constitutions of 1921 and 1935, laws, normative acts, and orders of ministries to name a few. An impact of the law «On the state language and the language of governance of the state and administrative authorities» of the Polish Diet from July 31, 1924, on the legal status of the Ukrainian language in self-governing bodies, is analyzed. According to the law, the Polish language was recognized as the state and official language in the administrative institutions of Halychyna, while using Ukrainian was permitted only in the administration of local authorities and local government bodies. As investigated, Ukrainian residents were eligible to apply in their native language and receive a response in the same language from local governing bodies only in Lviv, Stanislaviv, and Ternopil voivodships. In contrast, in the territory of Volyn and Polissia, while being allowed to submit statements or oral appeals in their native language to self-governing bodies, they additionally had to express a request to receive an answer in Ukrainian.
Most of the provisions of the Constitutions of 1921 and 1935, laws, and orders that regulated the use of the Ukrainian language in local government bodies, were not completely implemented, which was primarily because it was Polish officials who headed the local government bodies in Halychyna, and choosing to provide answers in the state or Ukrainian language, was usually decided in favor of the state one.

LVIV STATE ETHNOGRAPHIC MUSEUM DURING THE SOVIET OCCUPATION (1939–1941)
Authors: BANAKH Vasyl
Published: December 2022

Based on the analysis of previous research and archival sources, the position of key Ukrainian museum institutions in Lviv on the eve of the occupation of Western Ukraine by the Soviet Union in September 1939, is analyzed. In the region, there were many museum institutions, which preserved and popularized the historical and cultural heritage of the peoples who have inhabited the territory of Halychyna. It was investigated that among the Ukrainian museums the most powerful were the National Museum in Lviv which had been founded in 1905 by the initiative of Metropolitan Andrei Sheptytsky and the Museum of the Shevchenko Scientific Society in Lviv (NTSh Museum). For more than three decades, both institutions have replenished their repositories with respectable ethnographic collections and artifacts.
A drastic change in the situation after September 17, 1939, is demonstrated. Soviet occupation authorities conducted a detailed audit of all museums in Lviv and carried out their large-scale reorganization, in particular, of the entire ethnographic collections of the NTSh Museum in Lviv, the Dzieduszycki Museum, the City Ethnographic and Arts and Crafts Museums, and the Lubomyrski Museum. The Lviv State Ethnographic Museum was established based on their ethnographic collections. From now on, all museum institutions in Halychyna had to serve the ideological needs of the totalitarian machine of Soviet propaganda.
Due to the analysis of archival material from the State Archives of Lviv Region (DALO), the main directions of the Ethnographic Museum's activity and its gradual ideologizing, which manifested itself in the priority of Bolshevik propaganda, are analyzed. For instance, exhibitions, lectures, and exposition ensembles forming, organized by the Museum during the end of 1939 and the first half of 1941 strictly corresponded to the so-called «Marxist-Leninist» ideology and a «class» approach. All his public activities were controlled by the relevant party-ideological institutions and party officials. After the Nazi occupation of 1941–1944, the Lviv State Ethnographic Museum returned to the Soviet Bolshevik propaganda reality. Thus, it was stated that the events of the autumn of 1939, related to the occupation of Western Ukraine by the Soviet Union and the implementation of Bolshevism, radically changed the museum landscape of Lviv. Most of the museum collections were disbanded by the new Soviet government and new museums were created on their basis – the main task of which from now on was to promote the so-called «Marxist-Leninist» approach.

A presente pesquisa tem como objetivo o uso da Cannabis integrado ao tratamento convencional do câncer, tendo em vista que o aumento do número de pessoas diagnosticadas com essa patologia levou à busca por novas alternativas para aliviar os sintomas causados pelo tratamento quimioterápico. Diante disso, houve a necessidade de demonstrar a eficácia e os benefícios, bem como os riscos do uso da Cannabis sativa, com base em evidências científicas, a fim de promover com segurança a qualidade de saúde dos indivíduos acometidos por essa condição. Para tanto, foi necessário avaliar esta nova terapêutica, comprovando sua atividade para o alívio de sintomas causados pela quimioterapia em paciente oncológicos, identificando os riscos e benefícios. Realiza-se, então, uma pesquisa bibliográfica pelo método de revisão integrativa. Diante disso, verifica-se a relevância deste composto no controle de náuseas e vômitos e atividade analgésica, além da ação antitumoral e diminuição da insônia, ansiedade e depressão. O que impõe a constatação de que apesar de apresentar atividades terapêuticas comprovadas por pesquisas, há a necessidade de mais estudos para melhorar a compreensão sobre o fármaco, assegurando a eficácia e segurança da utilização da Cannabis.

Biotechnology has been an essential tool in the search for solutions and in the optimization of bioprocesses associated with issues of human, plant, animal, energy and also the balance of ecosystems on planet Earth. The objective of this research was to present an unconventional substrate (cellulose), in abundance on the planet, to be used as a substitute source of carbon and energy for biotechnology processes, with the possibility of increasing industrial production of biomass and energy. As basis for the research, an extensive literature review and quantitative and qualitative analyzes were carried out. Genetic Engineering techniques were used to enable the yeast Saccharomyces cerevisiae for partial cellulose degradation, through the use of genetic transformation methods to insert a plasmid carrying the cellobiohydrolase cDNA. It was found that the recombinant and biologically active cellobiohydrolase protein was expressed and excreted in haploid and diploid laboratory yeast strains. The analyzes allowed the visualization of cellulolysis halos around colonies of recombinant strains grown in solid YPD medium with 1% microgranular cellulose. The recombinant clones derived from the haploid lineage yielded in average of 1.70 mg ART/mL, while recombinant clones derived from the diploid lineage produced in average of 2.05 mg ART/mL.

A degradação do meio ambiente, pela ação do ser humano é um problema complexo, coletivo, amplo e multideterminado. Diante das cobranças legais, comerciais, publicitárias e sociais, as diferentes organizações têm enfrentado o desafio de conciliar desenvolvimento econômico e preservação ambiental. As várias noções e modelos de sustentabilidade fornecem caminhados nessa missão, sobretudo a International Organization for Standardization - Organização Internacional de Normalização - ISO 1400 e o Sistemas de Gestão ambiental (SGA). Nesse âmbito, as Instituições de Ensino Superior (IES) ainda encaram essa questão de maneira incipiente, apesar de sua responsabilidade social, ambiental e acadêmica. Objetivando apresentar um projeto de gestão ambiental numa IES privada da cidade de Piripiri (PI), indaga-se, qual o Impacto ambiental e financeiro do consumo desenfreado de água, energia elétrica e materiais descartáveis, bem como o despejo inadequado de lixo? Como justificativa, observa-se que a implantação do projeto implementou adaptações na estrutura física do local e fomentou campanhas educativas ligadas à gestão de água, energia elétrica, materiais descartáveis e lixo. Para estruturar a proposta, utilizou-se o framework Kaizen para a organização de um panorama sistematizado e acessível na identificação de dificuldades, elaboração de ações e delineamento de metas esperadas das intervenções.

Introdução: Um dos meios mais preventivos para o contágio de doenças é a vacinação. Estas são criadas através da inclusão de agentes patogênicos, tais como as bactérias, vírus ou toxinas. Uma vez instalados no corpo humano, as vacinas geram um estímulo à reação do sistema imunológico e a produção de anticorpos específicos em desfavor do agente patogênico. É fato que ela cura doenças e previne outras milhares. No Brasil, as vacinas são entregues à população em grande parte, por meio do Sistema Único de Saúde (SUS), passando por um controle de qualidade muito detalhado, tendo como base o que preceitua o Instituto Nacional de Controle de Qualidade em Saúde (INCQS). Objetivo: O objetivo deste trabalho é descrever sobre a eficácia, proteção e composição das vacinas do calendário nacional de vacinação. Materiais e métodos: Foi realizada uma revisão de literatura integrativa, onde foram coletados os resultados dos principais estudos contidos nas bases de dados científicas SciELO, LILACS e PubMed nas línguas portuguesa e inglesa. Resultados e discussão: Foram selecionados 11 artigos que se enquadravam nos objetivos e nos critérios de inclusão. Elaborou-se um quadro com o propósito de apresentar de forma objetiva as principais informações coletadas. Considerações finais: Para se garantir a eficácia das vacinas, sua produção passa por um rígido controle de qualidade, e se não obter um manejo adequado quanto ao armazenamento, transporte e manuseio, não surtirá efeitos suficientes aos usuários.

Nas duas últimas décadas tem ocorrido um aumento importante dos estudos na área da saúde sobre a violência, ocorrendo principalmente por conta do reconhecimento dela como um grave problema de saúde pública. Tendo essa realidade em vista, o objetivo deste trabalho foi caracterizar o perfil das notificações causadas por violência física durante o período de 2016 até 2020 no Estado do Pará. Este estudo possui caráter ecológico retrospectivo de abordagem quantitativa, com uso de dados secundários do Sistema de Informação de Agravos de Notificação (SINAN) e Sistema de Informações sobre Mortalidade (SIM). Os resultados estudo demonstraram que foram registradas 16.446 notificações de casos de violência física no Pará, no período de 2016 a 2020. Observou-se que 23,25% (n=3.823) das notificações foram pertencentes ao gênero masculino e 76,73% (n=12.619) ao feminino. Observou-se que a maioria das notificações de violência física no Pará ocorreu em pessoas pardas (73,95%), em seguida por pessoas brancas (12,43%) e por pessoas pretas (8,69%). Dessa forma, os resultados apontaram que as mulheres, pardas e jovens são mais suscetíveis à violência física, com a residência como o principal local de ocorrência. No que tange aos óbitos por causas agressivas, o gênero masculino (92,69%) e pessoas pardas (85, 39%) foram os que se destacaram. Portanto, reforça-se a necessidade de preparar os sistemas de saúde para o atendimento e acompanhamento das vítimas, inclusive com encaminhamentos a serviços específicos garantindo a inclusão em linhas de cuidado e serviços de proteção apropriados para cada indivíduo.

Objetivo: Elucidar sobre fatores de risco, fisiopatologia, complicações, prevenção e tratamento das úlceras de pressão. Metodologia: Realizou-se um levantamento bibliográfico a fim de inteirar-se sobre as lesões por pressão. Resultados e Discussão: As úlceras de pressão (UP) são evitáveis, porém frequentes nos enfermos. Representa o prognóstico do paciente e a qualidade do serviço de saúde ofertado. Os fatores de risco para UP são vários, como idade avançada, imobilidade, debilitação, hospitalização e intervenção cirúrgica. Os principais mecanismos para sua formação são: força de cisalhamento, pressão e fricção. As UP podem causar sérias complicações e até mesmo serem fatais. A prevenção consiste em identificar os pacientes suscetíveis no momento da internação e instituir medidas profiláticas, como superfície de suporte, reposicionamento frequente, nutrição adequada e gerenciamento de umidade. O tratamento das UP baseia-se na educação, otimização do paciente e correção de causas reversíveis. Conclusão: As UP representam um problema de saúde pública e apresentam alta incidência, por isso, deve-se investir em medidas preventivas, pois, além de serem mais efetivas, possuem menor custo quando comparado ao tratamento.
