Krytyczne zdarzenia życiowe jako przedmiot badań
Authors: Lalak Danuta
Published: January 2025

Przedmiotem rozważań jest biografia postrzegana jako źródło wiedzy o człowieku, jego życiu i środowisku, potencjale edukacyjnym i rozwojowym. W strukturę rozważań nad biografią wpisane są takie kategorie teoretyczne jak punkty zwrotne, zmiany statusowe, kryzysy, transgresje i transformacje tożsamości. Przedstawiam dwie  perspektywy badawcze – badania biegu życia (perspektywa obiektywna, badania ilościowe) stricte socjologiczne oraz badania jakościowe zogniskowane na indywidualnym doświadczeniu biograficznym (perspektywa subiektywna, badana jakościowe)  z akcentem na samorozwój, pokonywanie kryzysów, edukację. Proces zmiany życiowej przedstawiam na podstawie  studium przypadku ofiary przemocy domowej. Wykorzystuję zaczerpnięte od Gabriele Rosenthal (Erlebte und erzählte Lebensgeschichte, Frankfurt–New York, 1995)  wybrane aspekty analizy takie jak: punkty zwrotne istotne z punktu widzenia psychologii rozwojowej, przejścia statusowe, punkty interpretacyjne czyli  ważne punkty zwrotne,  rozumiane jako rekonstrukcje/ reinterpretcję przeszłości, teraźniejszości i przyszłości.
Podsumowując, to nie  zdarzenia kryzysowe same w sobie powodują zmianę, raczej wyzwalają one proces zmiany za którym kryje się wiele czynników podmiotowych. Te czynniki i ich doświadczeniowy charakter, mają szczególną wartość. Na ich wydobyciu i interpretacji  opiera się proces analityczny. Stosowane procedury badawcze,  zarówno te ugruntowane w istniejących praktykach jak i stosowane ad hoc przez badacza mogą być elastyczne i uwzględniać wszelkie nietypowe zjawiska i zdarzenia, które mają szansę pojawić się w polu badawczym.

Tekst skupia się na dwóch ważnych aspektach w biografii jednej z najsłynniejszych polskich projektantek form przemysłowych – Marii Chomentowskiej. Pierwszym zwrotem, definiującym całą jej przyszłą karierę zawodową, była decyzja o rezygnacji ze studiów malarskich i podjęcie nauki w pracowni prof. Jana Kurzątkowskiego na Wydziale Architektury Wnętrz Akademii Sztuk Pięknych w Warszawie. Podyktowana została w dużej mierze niezgodą na metody dydaktyczne stosowane wówczas na wydziale. Za drugi punkt zwrotny artykuł przyjmuje zainteresowanie projektantki kwestiami projektów dla dzieci i młodzieży. Sama idea designu skupionego na młodym użytkowniku stanowiła wówczas novum i wpisywała się w badania nad psychologią rozwoju dzieci i młodzieży, której wyniki dowodziły związków pomiędzy dobrostanem i rozwojem intelektualnym, a środowiskiem nauki i pracy. Pozwoliło to Chomentowskiej na stworzenie licznych projektów o innowacyjnej formie, które wpisywały się w nowy nurt tworzenia przestrzeni przyjaznej pracy i nauce. Przykładami realizacji utrzymanych w tym duchu są m.in. meble do pokoi dziecięcych, ławy szkolne, a w szerszym kontekście unikatowy na skalę kraju projekt wnętrz Katolickiego Uniwersytetu Lubelskiego. w tekście analizuję biografię Chomentowskiej pod kątem dwóch decydujących momentów, które stanowiły przełom w jej karierze oraz miały wpływ na kolejne pokolenia projektantów form przemysłowych.

Published: January 2025

The purpose of the study is to establish the direction of mobilization processes and quantitative changes in soil biota during long-term use of resource-saving treatments of meadow chernozem soil. The study was carried out in a long-term (established in 1973) stationary experiment in grain-fallow crop rotation (fallow – wheat – wheat – wheat – barley) under wheat (third after fallow) in the Omsk Agrarian Research Center in the southern forest-steppe of Western Siberia. The parameters of changes in the number of individual physiological groups of microorganisms and indicators of the biological activity of the meadow-chernozem soil under the third wheat after fallow under agricultural technologies with different levels of intensification, including the minimum-zero tillage system in crop rotation, were established. In separate periods of 2020 and 2021 with good soil moisture, the presence of a significant amount of plant residues in the variant with minimal-zero tillage, the number of oligonitrophils, phosphate-mobilizing bacteria increased to 200.0–451.0 million CFU/g. The use of complex chemicals significantly affected the number of nitrifying bacteria in the soil. The share of influence of the intensification factor in this case was 62.7 %. The largest amount of nitrifiers was observed when using complex chemicals (1.46–2.02 thousand CFU/g), as the intensity of tillage decreased, it decreased. The long-term minimization of the cultivation of the meadow-chernozem soil contributed to the accumulation of plant residues in the arable layer, which had a decisive influence on its biological properties. The total cumulative number of detected microorganisms on average for 2019–2021 was the highest with minimal tillage, exceeding plowing by 68.5 %. Over the years of research on the options for the use of means of intensification and against the control background, the highest grain yield was obtained with a moldboard tillage system, exceeding the minimum-zero one by 0.27 t/ha (9 %).

The purpose of research is to study the effect of organic forms of microelements in combination with and without phytase on the productive indicators of broiler chickens, intestinal microbiocenosis and its histoarchitectonics. As a result of an experiment conducted in 2021 in the vivarium of the Federal Scientific Center VNITIP of the Russian Academy of Sciences on 4 groups of broiler chickens of the Ross-308 cross, it was found that the use of organic forms of microelements in compound feeds in the form of L-asparaginates in an amount of 7.5 % of guaranteed norms contributed to better assimilation of metals, this had a positive effect on the physiological, productive and production indicators of poultry. In broilers, the diet of which contained a complex of organic forms of microelements in combination with phytase, the productivity indicators were higher in comparison with chickens of other groups, which was a confirmation of the better assimilation of feed nutrients by the bird under the influence of the enzyme introduced into the diet. In the study of the intestinal microbiome of broiler chickens that consumed feed with the addition of organic forms of trace elements in the form of L-asparaginates, both with and without phytase, already at the level of phyla, shifts were noted both in the composition of the microbiome and in the level of its biodiversity, which is also indirectly could affect the productive performance of poultry. Cluster analysis made it possible to establish a great similarity of the microbiome of the caecum of the intestines in poultry of groups III and IV, the diet of which included 7.5 % of trace elements in the form of L-asparaginates from the accepted norms, both with the addition of phytase (group III) and without it (group IV)). Histological studies have shown that the organic form of trace elements (OMEK-broiler) in the form of L-asparaginates did not significantly affect the change in the histoarchitectonics of the intestine, and the addition of phytase against the background of asparaginates contributed to the smoothing of mild mononuclear infiltration.

The purpose of research is to study the helminth fauna, distribution, seasonal and age dynamics of helminthiases in cattle. Objectives: to study the species composition of causative agents of helminthiases in cattle, their distribution in the Trans-Baikal Region, the degree of infestation of animals (EI, AI) for further development of a plan of treatment and preventive measures. Helminthiases of cattle in the Trans-Baikal Region are widespread, and they should be divided into gastrointestinal, which consist of 3 species of trematodes, one species of cestodes and 13 species of nematodes: fascioliasis (EI – 11.0 %), paramphistomatosis (EI – 7 .0 %), monieziosis (EI – 12.1 %), bunostomiasis (EI – 48.6 %), cooperiosis (EI – 20.5 %), ostertagiosis (EI – 11.7 %) and nematodirosis (EI – 6.1 %); pulmonary: dictyocaulosis (EI – 11.5 %); organs of vision: thelaziosis (EI – 25.0 %). Adult animals are infested with cestodes by 2.5 % with IS on average 2 ind., and strongylates – by 46.3 % with AI on average 183 ind. Monieziosis infects mainly young animals up to a year old with AI from 1 to 4 specimens. on an animal. In the forest-steppe zone, EI and AI by helminthiases of the digestive tract are much higher than in the steppe zone, and dictyocaulosis and thelaziosis, regardless of zones, are widespread. Among animals older than two years, dictyocaulosis is extremely rare and does not pose a serious danger as a source of invasion. When infested with telazia, the species Th. prevails in young animals. skryabini, and in adults – Th. gulosa. Animals of the steppe and forest-steppe zones were affected by thelaziosis by 14.7 and 11.2 %, respectively. With thelaziosis of cattle, the intermediate host is field flies of the species Musca autumnalis, which appear in the 2nd half of May and disappear at the end of September.

Published: January 2025

The purpose of research is to study the active and passive monitoring of African swine fever (ASF) carried out in the Russian Federation, as well as to carry out a retrospective analysis of reported outbreaks of the disease in the wild boar population to determine the most effective control measures. The objects of the study are data on notified outbreaks of ASF in the wild boar population of disadvantaged subjects of Russia, collected in a single database adapted for GIS analysis. A retrospective analysis of ASF outbreaks and zoning of the territories of subjects according to the level of risk of infection for the wild boar population was carried out in terms of the distribution of animals found dead or their remains, as well as hunted with a confirmed diagnosis. Outbreak data was obtained from the regional veterinary services of the constituent entities of Russia. As a result of a retrospective analysis of ASF outbreaks among the wild boar population, it was found that the effectiveness of monitoring activities is due to a greater extent to the detection of positive carcasses and remains of wild boars, this is in good agreement with the literature data on the importance of passive monitoring of this infection in European countries. Also, as a result of the GIS analysis, the subjects of the Russian Federation were identified, on the territory of which zones of high risk of new ASF epizootics are formed. These territories include the subjects of the Far East Region, the center of the European part of Russia – Ryazan, Orel, Tula, Yaroslavl, Nizhny Novgorod and Moscow Regions, also the Kaliningrad Region, and some subjects of the southeast of the European part of the country – Samara, Saratov and Rostov Regions. Thus, in order to increase the effectiveness of the anti-epizootic measures applied, especially in those regions where the main task is the elimination of ASF, it is necessary to focus the main efforts on carrying out special measures to search for corpses and remains of wild boars – passive monitoring.

Authors: Guseva Ekaterina
Published: January 2025

The purpose of research is to study the possibility of using a complex food additive (CFA) Konstanta and Konstanta MIX as a preservative to ensure microbiological safety and increase the shelf life of antler hydrolyzate. Objectives: to determine the optimal concentration of Konstanta and Konstanta MIX CFAs to reduce bacterial contamination in velvet antler hydrolysate; to determine the shelf life of antler hydrolyzate when using efficiency. The study was carried out in the laboratory for the processing and certification of antler products of the All-Russian Research Institute of Antler Reindeer Breeding department of the FSBSI Federal Altai Scientific Center for Agrobiotechnologies (Barnaul, Altai Region) in 2022. To disinfect and increase the shelf life of finished products, antler hydrolyzate with a volume of 300 ml was added with an efficiency factor of 1.5; 3.0; 4.0 % in accordance with the instructions on the allowable rates. Microbiological indicators were determined 1 month after the samples were made. After determining the optimal CFA, which made it possible to obtain a prototype that meets all the standards of TR TS 021/2011, an experiment was carried out to determine the shelf life. To do this, samples were prepared, packed in a glass container with a sealed lid, and put on display. Next, a microbiological evaluation of the product was carried out. When using the Konstanta CFA, it was possible to achieve a decrease in microbiological indicators for the groups QMAFAnM and yeast, mold and fungi, BGKP – to the complete absence of representatives of this group. But the prototypes did not meet the requirements of TR TS 021/2011 and were not suitable for further use. When testing the efficiency of Konstanta MIX in the amount of 4 % of the specified volume, a clean sample was obtained according to microbiological indicators. When determining the expiration date using the efficiency factor Konstanta MIX of 4 %, it was found that the hydrolyzate remains sterile for 6 months, and on the 7th month there is a growth of microorganisms in the QMAFAnM group.

Authors: Naumov Vladimir Arkadievich , Velikanov Nikolay , Sharkov Oleg
Published: January 2025

The purpose of the study is to form a mathematical model of gas-dynamic processes occurring during vacuum-impulse drying and analyze their dependence on the determining parameters. As an object of study, the operation of a water-ring vacuum pump of domestic production VVN1-1.5 is considered. The influence of leaks on the dependences of the pressure in the receiver and the mass flow rate of gas on time for a given volume of the receiver is studied. With an increase in the intensity of leakage (leaks) from 0.08 to 0.2, the pressure decreases from 20 to 9 kPa. This indicates a noticeable effect of leaks on the process of pumping air. It can be seen how the level of vacuum that can be achieved decreases with an increase in the leakage intensity. This reduces the time to reach it. Similarly, the mass flow rate decreases with increasing leakage intensity. With an increase in the volume of the vacuum chamber, the time to reach a given pressure increases, and with an increase in the diameter of the pipeline, this time decreases. In the time interval from 20 to 180 s, the pressure and mass flow drop by about 5 times. An increase in the leakage intensity by a factor of 2.5 leads to a decrease in pressure and mass flow at the final stage by about a factor of 2. It was established that the nature of the dependence "pressure, mass flow – time" at the initial moment of time from 20 to 40 s is steep, with increasing time it becomes flat. It seems appropriate in the future to improve the proposed model to take into account the effect of temperature and air humidity on the performance of liquid ring vacuum pumps, as well as the evaporation rate of various food products.

Published: January 2025

The purpose of the study is to create a variety of hard spring wheat with high yield, grain quality, pasta properties, resistance to abiotic and biotic factors in the conditions of Western Siberia. The experiments were carried out in pairs at the station of the durum wheat breeding laboratory of the Federal State Budgetary Scientific Institution Omsk ARC (southern forest-steppe) and at the Stepnoy Experiment Station in the Omsk Region. Based on the results of the 2015–2022 study in the nurseries of competitive variety testing, methods of creation, morphological and agrobiological features of the variety are presented. The variety has a high stable yield, resistance to drought, lodging, leaf and stem rust, powdery mildew and hard smut. In terms of grain yield, on average for 2015–2022 the new variety exceeds the Jemthujina Sibiri standard in the conditions of the southern forest-steppe by 0.37 t/ha at a level of 4.22 t/ha. In the steppe zone at the "OP Stepnoy" in 2017–2022 the average yield was 3.50 t/ha, which is 0.38 t/ha higher than the standard. Omskij lazurit exceeds the standard in terms of grain quality: by nature – by 10 g/l, glassiness – by 3.4 %. The content of protein (13.92 %) and gluten (28.3 %) is at the level of the standard, the evaluation of dry pasta by color is 3.6 points, boiled pasta is 3.7 points (the standard has 3.2 points). In the system of the State variety testing, Omskij lazurit was tested in 2021–2022 on variety plots of the steppe and forest-steppe zones of the 9th, 10th, 11th regions of the Russian Federation. It has been included in the State Register of Breeding Achievements since 2023 in the 10th and 11th regions.
DIFFERENT PRECOCITY CORN HYBRIDS REACTION TO SOWING TIME IN THE MIDDLE URALS
Authors: Ovchinnikov Pavel
Published: January 2025

The purpose of the study is to substantiate the optimal timing of sowing corn in the conditions of the Middle Urals. At the Ural Research Institute of Agriculture, the reaction of three corn hybrids with different early maturity to the sowing dates was studied. Sowing was carried out on May 5–9 and May 25. Observations and records were carried out according to the accepted methods of the All-Russian Research Institute of Maize. The results of the study showed that in the conditions of the forest-meadow zone of the Middle Urals, the transfer of the sowing date to the beginning of May leads to an advance in the flowering phase of the cob by 16 days, and the milky ripeness of grain by 15 days relative to sowing at the end of May. This provides additional resources of heat and time for full filling of grain. A stable effect of sowing time on the yield of dry matter was not found. Grain yield, on the contrary, was significantly higher when sown in early May. The maximum grain productivity was noted in the early maturing hybrid Kubansky 102 MB (4.03 t/ha). A positive effect of the early sowing period on the share of grain in the dry matter of all three hybrids and a decrease in the harvesting moisture content of grain by 12.4 percentage points were noted. The increase in the grain component in the structure of the plant had a positive effect on the content of fodder starch in the dry matter. Correlation analysis showed a close positive relationship between the yield of starch and the yield of corn grain and a weak relationship between this indicator and the yield of dry matter. This makes it possible to use the grain yield as an integrated indicator of the productivity and nutritional value of corn grown for feed in the conditions of the Middle Urals.
Eksperymenty z tożsamością w kinie queer
Authors: Radkiewicz Małgorzata
Published: January 2025

Kino queer jest obszarem negocjacji sposobów reprezentowania nienormatywnych tożsamości seksualnych i genderowych za pomocą eksperymentów z narracją i środkami filmowego wyrazu. Analiza wybranych filmów pozwala pokazać, czym charakteryzują się postawy poszczególnych twórców wobec queer i jak przekładają się one na narracyjne oraz stylistyczne rozwiązania. Poetyka New Queer Cinema, określana mianem „Homo-Pomo”, zawierająca w nazwie homoseksualizm i postmodernizm, jest tylko jedną z możliwych opcji. Jej inwarianty widoczne są już w twórczości Dereka Jarmana, uznanego za głównego przedstawiciela tego nurtu, ale niedającego się zamknąć – jako „artysta queerowy” – w jednym schemacie twórczym. Dla Isaaca Juliena najważniejsze było włączenie do problematyki queer kwestii związanych z rasowością i wielokulturowością, pozwalających na wieloaspektową reprezentację i reinterpretację zjawiska „czarnej queerowości”. Innym ujęciem tożsamości queer jest kwestia transgenderowości, która powraca w filmie Kimberly Peirce odtwarzającym historię Brandona Teeny i jego/jej genderowych wcieleń. We wszystkich analizowanych filmach obecna jest perspektywa krytyczna pozwalająca stworzyć queerowe reprezentacje alternatywne względem normatywnych wzorców (i obrazów) tożsamości.

Published: January 2025

This article discusses the contributions that the LeME Transforma Project can bring to the professional and citizen formation of undergraduate students. Therefore, the narratives of these students, shared during the training period in which they experienced Statistical Learning Projects, were qualitatively analyzed using the methodology of the Collective Subject Discourse. The undergraduates recognized the tools that Statistics provides for daily and teaching activities, which may be a reflection of the developed pedagogical strategy. Furthermore, they associated Statistics with financial issues and Probability, relating the knowledge derived from these areas to daily tasks. Participation in the project proved to be important in the construction of teaching knowledge, not only of content but also experiential. Therefore, the project and the proposition of an investigative methodology can contribute to a formation focused on critical citizenship, as well as in the constitution of teachers concerned with the social role that Statistics plays in the lives of their students.

Published: January 2025

Industry 4.0 is bringing about a rapid advancement in technology, particularly in the military industry. This robot was designed to reduce danger to TNI members while monitoring military operations more swiftly and safely. The application of IMU sensors for acceleration movements, measurement of control system error values, and trajectory tracking with multiple pathways are the three modes of the robot control system observed in this study. We assess each of these modes using an analytical observational method. In addition to an MPU 6050 ultrasonic and gyro sensor to detect movement using an accelerometer and gyroscope, the robot is equipped with a rotational encoder sensor to link the DC motor rotation. The PID control approach uses inverse kinematics to regulate the DC motor. The exam is administered on a track that has squares, triangles, and circles as obstacles. According to test results, the tachometer's inaccuracy rate in RPM is about 1.2% higher than the rotary encoder. The movement success percentage for the omni-wheel robot is 89.31%. Square trajectories have an average error rate of 11%, circular trajectories of 15%, and triangular trajectories of 4.17%. The motor rotation speed is most stable along the triangle path. Overall, this study demonstrates the accuracy and speed with which a mobile omni-wheel robot equipped with a control system can peek. This could raise military operations' level of efficiency and safety

Published: January 2025

Coal mining activities often produce acid mine drainage characterized by low pH values below 5 and high concentrations of heavy metals including iron (Fe). If the water is not managed properly, it can impact the environment due to the influence of acidity and high concentrations of dissolved metals. This research aims to utilize the combination of activated limestone and fly ash by heating at 110°C for 3 hours for acid mine drainage treatment, namely neutralizing pH and adsorbing heavy metal Fe. The selection of adsorbent materials was based on economic considerations, abundant availability, and utilization of fly ash waste. The method used was batch adsorption experiments with contact times of 30 and 60 minutes. Acid mine drainage from coal mine with initial pH 4.55 and Fe metal concentration 7.58 mg/L. The adsorbent combination of limestone and fly ash in the ratio of 1:1, 1:2, and 2:1. From the experimental results, it was obtained that the adsorbent combination was able to neutralize pH up to 6 and remove Fe up to 1.35 mg/L was the ratio of 1:2 with a stirring time of 30 minutes. So it can be concluded that adding fly ash dose 2 times compared to the dose of limestone is more effective to raise the pH value and remove Fe heavy metal, because the higher the dose given, the more ion adsorption sites will be available

Salah satu komponen paling penting dari upaya penyelamatan sandera adalah kesepakatan tentang pembebesan sandera. Kesalahan petugas dalam mengambil tindakan selama proses negosiasi dapat membahayakan keselamatan personel dan petugas serta korban yang disandera. Kurangnya komunikasi sering menyebabkan konflik yang berbahaya yang dapat menghambat penyanderaan. Untuk mengatasi masalah ini, kami merancang robot negosiasi khusus yang dipersenjatai untuk memastikan keselamatan dan keamanan petugas dalam menjalankan tugas, baik dalam situasi perang maupun operasi pembebasan sandera. Dengan memiliki senjata, petugas yang bertanggung jawab atas keselamatan korban dapat melakukan tugas mereka tanpa mengorbankan keamanan pribadi mereka. Robot militer ini memungkinkan negosiasi dan pemantauan tanpa mengancam nyawa, memberikan pendekatan yang lebih efisien dan aman. One of the most important components of hostage rescue efforts is an agreement on hostage release. Mistakes by officers in taking action during the negotiation process can endanger the safety of personnel and officers as well as victims being held hostage. Lack of communication often leads to dangerous conflicts that can hinder hostage taking. To overcome this problem, we designed a special negotiation robot that is armed to ensure the safety and security of officers in carrying out their duties, both in war situations and hostage release operations. By having a weapon, officers responsible for the safety of victims can carry out their duties without compromising their personal safety. These military robots enable negotiation and monitoring without threatening lives, providing a more efficient and safer approach. Additionally, the robot's ability to operate autonomously with the help of artificial intelligence allows for quicker assessment of the situation and more appropriate responses, thereby increasing the chances of success of a rescue mission without increasing risks for the humans involved. The robot is also equipped with advanced sensors and machine learning algorithms that can detect changes in a hostage taker's behavior and body language, providing valuable information to the negotiation team to devise more effective strategies. Thus, the implementation of this technology not only increases the security and efficiency of military operations, but also paves the way for further innovation in the use of robotics and Artificial Intelligence in various aspects of defense and security

Published: January 2025

Globalization has become the main driver for the wave of information and technological innovation, stimulating the transformation of consumers to become more sensitive to quality standards and the value of the products offered. This research aims not only to explore how quality control utilizes sophisticated statistical tools in curbing the level of product defects in the corporate environment, but also as an important milestone in understanding the dynamics of change in an increasingly connected era of globalization. This research uses the Statistical Process Chart method. In an effort to control quality, statistical analysis becomes the main weapon, with check sheets and histograms acting as navigation that leads to understanding complex data. The control chart p becomes a sentinel that monitors the traces of defective products, keeping them within the desired statistical control limits. However, it is not enough to simply observe; The next step is to explore the root of the problem, which is depicted through a cause-and-effect diagram that details the factors of materials, labor, machines and production methods as the main determinants of the success or failure of a product. The analysis results show that even within control limits, real challenges arise from factors that are the main triggers for product damage, such as remaining pieces which cause damage of 29,160 grams, followed by damage due to crushing of 2,900 grams. From here, conclusions and recommendations develop, guiding improvement steps to ensure quality standards are maintained, in line with increasingly stringent and diverse global market demands

Farmers are forced to water each crop individually or wait to switch off the water pump. to avoid this, water management needs to be optimized—that is, it needs to be done on schedule, in the appropriate quantity, and throughout a wide area in an effective manner. That is hybrid communication between online and offline communication. To run this system will use 3 nodes, for details 1 node in the irrigation section, 1 node in the monitoring section of land and soil quality, and 1 node in the section to control data or can be said to be a semi-server to give commands to 2 nodes offline. To see if the system still communicates with each other and runs according to the block diagram that has been designed, an Android application will be made to monitor the system. Where if there is a failed data update or data change in the results of the automation system, a notification will come out to check the system as a whole. To support this research, several sensor calibrations were carried out which resulted in an average accuracy level above 90 percent. For the overall system test, 10 experiments were carried out at different times to see the reliability of the system
