The research goal was to study how selective media with zinc at high concentrations influenced the survival rate and fertility of pollen grains in common buckwheat. The research object was the regenerated plants (common buckwheat variety Izumrud) created at the Laboratory of Agricultural Biotechnology of the Federal Scientific Center of Agricultural Biotechnology of the Far East named after A. K. Chaika and tolerant to CuSO4×5H2O at concentrations of 161 and 184 mg/l. The plants were cultivated on selective media with ZnSO4×7H2O at concentrations of
808–1 313 mg/l and subcultured on MS nutrient media without the toxicant. The isolated in vitro objects were cultivated in test tubes with cotton gauze plugs at 4,000 lx, 22–25 оС, and 16-h
photoperiod under culture room condition. The test-tube plants were transferred into pots under
controlled conditions in a light room. The fertility of the pollen in the regenerated plants was tested according to the methodology of Z. P. Pausheva using Gram’s iodine solution. The buckwheat
genotypes obtained by sequentially using selective media with copper and zinc showed high stress
resistance and survivability. The studied plants demonstrated a high rate of regeneration after exposure to high doses of zinc. The percentage of fertile pollen grains ranged from 92.6 to 100.0%
among the experimental variants. The fertility of the plants obtained using the copper salt at a concentration of 161 mg/l was 98.6% on the selective media with zinc, which was higher than in the
variant with the use of zinc and copper (184 mg/l, 95.0%). The artificial pollination among plants
in the experimental variants allowed us to obtain underdeveloped seeds due to illegitimate pollination because the obtained in vivo plants were short-columnar. In general, buckwheat demonstrated
high tolerance to heavy metals as evidenced by the high fertility of its pollen grains.
Research on the efficiency of using milking machines

Dairy farms use various technological lines for primary milk processing. The task
is to identify the most rational line that does not require manual labour. Dairy production belongs
to the food industries with their pronounced specifics: non-stationary quality indicators of raw
materials, biological activity of raw materials (perishable) and processed products, strict sanitary
and hygienic standards of production, seasonality of loads, etc. An analysis of the various stages
of dairy production shows that ensuring the required quality of finished products and their release
in the required range are difficult and often fail. This problem can be solved if we create flexible
technological schemes for the production of products, which would take into account the changing
indicators of the quality of raw materials, and express methods for determining the latter. One of the reasons for the decrease in the efficiency of using milking machines is a violation of their vacuum mode. The degree of tension of the drive belts also affects the decrease in pump performance.
Weak tension leads to slipping in the pulleys and, as a consequence, to wear and loss of pump
performance. The article describes a study of increasing the efficiency of using milking machines,
and evaluates this efficiency.

Published: February 2025

A conceptual model of a diagnostic system for assessing the technical condition
is proposed, on the basis of which it is possible to determine the ways of implementing a new
approach in the design of integrated information measuring systems for monitoring the functional
characteristics of the internal combustion engine (hereinafter referred to as ICE). With the help
of established functional connections, it is possible to make a transition to the algorithmization of the diagnostic system under study for further development of the scientific and technological
foundations of its application. Approbation of the proposed conceptual model was carried out by
experimental studies of changes in the parameters of the free run-out of the YAMZ-53445-22 engine. As a result, it was found that the engine run-out time is on average 3,2 seconds, during which
time the crankshaft rotation speed changes from 2 751 min-1 to 709 min-1. The engine crankshaft
acceleration ranges from minus 138 s2 to 0 s2. The magnitude of the reactions of the supports
during the run-out changes from 402 Н at a speed of rotation of the crankshaft 2 663 min-1 to 0 H
at 709 min-1. The maximum value of the torque during the run-out is minus 234 Hm at a speed of
rotation of the crankshaft 2 663 min-1. The power of mechanical losses calculated relative to the
current value of the torque on the supports and the corresponding value of the crankshaft rotation frequency varies from minus 63 kW to zero with a similar change in the crankshaft rotation
frequency. The developed conceptual model takes into account the totality of input effects on the
system, the states of the system elements and the relationship of the system elements, which is
confirmed by the experimental data obtained.

Published: February 2025

A technology of obtaining microbial protein based on yeast fungi Saccharomyces
cerevisiae has been developed. This technology includes preparing of working solution in a form
of 10% yeast suspension, activation of nucleases with sodium chloride (0.1 H) under the condition of an acidity of at least 9.0 pH and a temperature of 40 о
С for 60 minutes; centrifugation of
biomass; separation of culture liquid; introduction of enzymes; drying and grinding. The process
of enzymatic hydrolysis of pressed yeast with proteolytic enzyme preparations Protosubtilin,
Papain and Bromelain in various dosages (1–5%) to the total mass of raw materials and water
has been investigated. The conditions for the fermentation process are as follows: Protosubtilin
(6.5 pH, 40 о
С for 12 hours), Papain (8.75 pH, 40 о
С for 12 hours), Bromelain (5.5 pH, 40 о
С for
12 hours). As a result of enzymatic hydrolysis, a high protein yield of 45.6% is observed at 4%
Bromelain hydrolysis. When Bromelain is applied in a quantity of 5% the content of free amino
acids of proline, cystine and methionine in the resulting protein microbial preparation increases
in comparison with the enzyme Protosubtilin. When Papain is applied in a quantity of 4%, the
content of aspartic acid, lysine, histidine, and methionine increases compared to Protosubtilin
and Bromelain. Consequently, each of the studied enzyme preparations, despite its specificity,
has different fermentation ability.

One of the main factors affecting the efficiency of agricultural enterprises engaged
in crop cultivation technology is the availability of personnel. Over the past years, there has been a
tendency to reduce the population in a number of regions. In the proposed work, an analysis of the
impact of living labor energy costs on the total energy costs associated with the production of agricultural products was carried out. Considering that the main activity of Amur region is agricultural,
it is advisable to assess the energy consumption of living labor, taking into account both the main
and auxiliary personnel involved in the technology of cultivating agricultural crops. The amount
of total energy consumption associated with the production of agricultural products is significantly
influenced by means of mechanization and, in particular, machine-and-tractor units, which are
used in the technology of its cultivation. In recent years, in the region there has been an increase in
sown areas mainly due to previously abandoned in hard-to-reach places and small-contoured peasant farms. Therefore, it is very important to correctly determine the necessary means of mechanization, taking into account the presence of labor, which will ultimately affect the volume of products received and its cost. It was established that the value of productivity of machine-and-tractor
units had a great influence on the value of energy consumption of live labor due to a decrease in
the value of skidding. This is especially important for energy means with a wheel formula 4K2 for
a better implementation of traction and adhesion properties due to the use of specially installed
devices. The conducted studies have shown that reduction of energy consumption of human labor
in the of agricultural crop cultivating technology in the conditions of Amur region is possible by
increasing the traction and adhesion properties of energy means through the rational redistribution
of the adhesion weight within the machine-and-tractor unit itself.

The article discusses arabinogalactan as a source of soluble dietary fiber, produced
in accordance with the requirements of regulatory documentation at the JSC "Ametis" (Amur region). The content of soluble dietary fiber in the amount of 98.8% in arabinogalactan is confirmed
from the testing center of LLC "Expert Bio" (St. Petersburg). In the process of work, the organoleptic indicators of the obtained fortified fermented milk drinks (taste and smell, color, consistency) were determined and described, during the evaluation of which it was established that the
obtained samples met the requirements for fermented milk drinks. Research has been carried out
to determine the optimal conditions for measuring the structural and mechanical characteristics of
fermented milk drinks, such as dynamic viscosity, which depends on the shear stress of viscous
products and the shear rate gradient. Analysis of the data obtained and subsequent interpretation of
the results allows us to develop a technology for the production of fermented milk drink with high
consumer properties. Data on the effect of starter type and dietary fiber used on the structural and
mechanical properties of obtained samples of fermented milk drinks are presented. Mathematical
equations were obtained that reflected the dependence of the viscosity of fermented milk drinks
on the component composition. The correlation coefficient of the obtained dependencies reflects
the existing strong inverse dependence of dynamic viscosity on the type of starter cultures and the
added soluble dietary fiber. More over, the analysis of dependencies showed that the introduction
of soluble dietary fiber into the samples led to a more rapid restoration of the structure of drink
after destruction.

Ecological balance of soils lies in the ability of self-repairing and purifying. These
properties can be provided by viable microbiological communities inhabiting the soil layers. An
increase in microorganism species diversity indicates the stability of the ecosystem and the provision of plants with necessary nutrients, as well as the soil ability to cleanse itself and maintain
ecological balance. The effective microorganisms of the preparation "EM∙1 microbiological fertilizer "Vostok EM-1" are able to increase the overall soil biogenicity by increasing the beneficial
microbiota. As a result, there is a natural inhibition of pathogens and a decrease in plant immunity
(pathogenic and opportunistic pathogenic microflora). It helps to increase the yield and quality of grown products even in one season of using the preparation. Research studies in different
soil and climatic conditions in short-term and long-term periods confirm the effectiveness of the
preparation "EM∙1 microbiological fertilizer "Vostok EM-1". This preparation contains more than
80 strains of microorganisms and fungi, the main ones of which are lactic acid, photosynthetic and yeast. In addition, the composition includes nitrogen-fixing bacteria, yeast, plant growth
regulators, soil acidity regulators, ammonifiers, oil-oxidizers, nitrifiers, bacterial growth regulators, phosphorus-mobilizing, cellulose-decomposing bacteria, actinomycetes and fungi. Thus, the
principle of consortium is not only to replenish soil microflora, but also to strengthen and direct
microorganisms present in the soil to maintain ecological balance in the soil. When increasing and
stimulating the activity of soil microbiota, the processes of humus formation are accelerated and
intensified as the most important factor in optimization of soil ecological state. Due to this, not
only does the stability of soil biological diversity increase, but it also has a positive effect on the
yield of cultivated crops.

This article discusses the impact of diet adjustments on the milk productivity of
newly calved cows. The results of research conducted on the basis of scientific and economic
experiments are analyzed. The conclusion is made about the importance of introducing feed additives into the diet of newly calved cows to increase milk yield and maintain animal health. The
influence of various factors, such as feed quality, composition and balance, on the lactation process
is discussed. Particular attention is paid to the role of milk productivity in the economics of dairy
production. Nowadays, feed additives are an integral part of newly calved cow feeding. They are
an important tool for maintaining and improving the metabolism of cows, which helps them enter
the lactation stage more easily. The study demonstrated that the introduction of "Cowfresh" feed
concentrate at the beginning of the lactation period in combination with "Active Mix" liquid premix had a positive effect on the productivity and health of cows. This made it possible to reduce
the weight loss of cows and accelerate its recovery, as well as maintain both quantitative and qualitative indicators of dairy products. The results of the study showed that the use of feed additives
not only helped to increase milk yield, but also increased the fat and protein content in milk. It is
especially important for economic efficiency in agricultural production. Thus, proper feeding of
newly calved cows is a key factor determining their productivity and the profitability of dairy production as a whole. Feed additives "Cowfresh" and "Active Mix" can significantly improve these
indicators, providing more efficient feed utilization and reducing milk production costs.The article
is of interest to specialists in the field of livestock farming, as well as to anyone interested in the
issues of proper feeding and maintenance of cattle.

This study was devoted to the study of changes in the biochemical composition of
the blood of sows with hepatopathy (acute and chronic hepatosis, liver cirrhosis). Groups of sows
were formed on the basis of macroscopic changes in the liver, identified during their post-mortem
examination. Blood for biochemical research was taken from sows before slaughter. The studied
blood biochemical parameters were grouped into 4 serum biochemical syndromes of liver diseases: inflammatory-mesenchymal, hepatodepressive, cytolytic and cholestatic. Changes in the blood
composition of sows, characterizing the inflammatory-mesenchymal syndrome, were established
in all studied hepatopathy. A positive thymol test, a decrease in the albumin-globulin ratio, an
increase in the concentration of globulins were caused by dysproteinemia. Its development is associated not only with inflammatory, but also with dystrophic, necrobiotic and necrotic changes in
the liver. The most significant decrease in these indicators was found in liver cirrhosis. Cytolytic
changes were established in all studied hepatopathy. To a greater extent, these changes (increased
activities of transaminases, bilirubin concentration) were expressed in the blood of sows with
acute hepatosis. With cholestasis syndrome, a number of typical changes were absent in the blood,
which was due to a decrease in the formation of cholesterol and direct bilirubin in the liver in
chronic hepatosis and cirrhosis. An increase in the activities of γ-glutamyl transpeptidase (higher
than the reference values) and alkaline phosphatase (in comparison with the indicators of sows
without signs of hepatopathy) were more pronounced in the blood of animals with signs of chronic
hepatosis and liver cirrhosis. The data obtained indicate severe metabolic disorders in sows with
the development of chronic hepatopathy. The results of the research can be used in diagnostic work
and in monitoring the effectiveness of ongoing therapeutic and preventive measures.

Objective

Diabetes is a leading cause of death in the USA. Previous studies have found substantial racial and ethnic and geographical disparities in diabetes mortality, however research considering racial and ethnic and geographical disparities simultaneously has been limited. To fill this gap, we estimated trends in diabetes mortality rates from 2000 to 2019 at the county level for five racial and ethnic populations.

Research Design and Methods

We applied small-area estimation methods to death registration data from the US National Vital Statistics System and population data from the US National Center for Health Statistics and corrected for misclassification of race and ethnicity on death certificates.

Results

Age-standardized diabetes mortality rates decreased in the USA from 28.1 (95% uncertainty interval 27.9–28.2) in 2000 to 19.1 (19.0–19.2) deaths per 100,000 population in 2019. In 2019, national-level rates were highest for the AIAN population (35.6 [32.1–39.4]), followed by the Black (31.9 [31.5–32.3]), Latino (19.7 [19.3–20.2]), White (17.6 [17.5–17.8]), and Asian (12.6 [12.1–13.1]) populations. There was substantial heterogeneity in diabetes mortality rates across counties within each racial and ethnic population, with the AIAN population experiencing the greatest heterogeneity in 2019 (IQR 18.7–50.3 [median 31.9]). For each racial and ethnic population, mortality rates declined in most counties from 2000–2019.

Conclusions

Since 2000, progress has been made in reducing diabetes mortality rates. Nonetheless, diabetes mortality remains too high for many Americans. Interventions focusing on communities at highest risk are vital to resolving persistent health inequities.

Fleas are small, wingless insects that feed on animal blood. In addition to being a major annoyance, they could unfold illnesses
and result in allergic reactions or anemia of their hosts. There are more than 2,200 species of fleas recognized worldwide.
Two common species of flea are the cat flea (Ctenocephalides felis) and the dog flea (Ctenocephalides canis). These parasites
can reason enormous pain for both animals and human beings. In greater critical instances, they will make a contribution to
anemia and transmit various illnesses, inclusive of tapeworms, bacterial infections, and rickettsial infections similar to typhus.
This paper discusses the importance of hygiene in order to avoid flea infestation and its related health hazards. It remains
particularly important that owners, health professionals, and the community are made more aware of the flea biology, the
range of pathogens they host, and basic principles of hygiene.

Published: February 2025

The low standard deviation in science scores suggests a considerable number of students with below-average performance, highlighting the need for more effective teaching strategies. This situation calls for a re-evaluation of the methods used in science education. This study aims to evaluate the impact of experiential learning approaches (indoor and outdoor) on the academic achievement of elementary school students, especially on the science learning outcomes of fifth grade students. The method used is quantitative with an experimental design, where two control groups are compared: class VA using outdoor learning and class VB using indoor learning. This study involved a pre-test and a post-test to measure the development of students' science learning outcomes after the learning intervention. The results showed a significant correlation between experiential learning strategies and academic achievement. The data indicated that both male and female students showed better grades when learning using the outdoor approach compared to indoor. In conclusion, although there was no interaction effect between learning strategies and gender, there was a significant difference in academic achievement between students who participated in outdoor learning and those who participated in indoor learning. Outdoor learning has been shown to be more effective in improving science learning outcomes than indoor learning.

The rising number of older adults in Indonesia, particularly those living with non-communicable diseases (NCDs) like diabetes mellitus (DM), presents significant challenges in enhancing their quality of life. This study investigates the impact of combining autogenic exercise with Al-Quran murottal on the quality of life among the elderly with DM. Employing a quasi-experimental design with a pre- and post-test approach, the research involved 89 elderly participants who met the inclusion criteria. These participants were divided into two groups: an intervention group, which received regular sessions of autogenic training combined with Al-Quran murottal, and a control group, which practiced self-directed internalization. The WHOQOL-OLD instrument was used to assess quality of life, with data analyzed using paired t-test and independent t-test. The findings revealed a significant improvement in the quality of life for the intervention group, as reflected by an increase in the average score from 49.42 to 74.72 (p < 0.05). Conversely, the control group experienced a minor, statistically insignificant decline in quality of life. These results demonstrate that integrating physical and spiritual elements, such as autogenic exercises and Al-Quran murottal, effectively enhances the quality of life for older adults with DM, offering a holistic approach to improving their well-being.

Introduction

Healthcare workers (HCWs) have reported COVID-19 pandemic-related adverse mental health impacts. We examined the demographic profile of HCWs who self-referred for mental health treatment, how referrals changed over time in relation to waves of COVID-19, what the main problem was for which HCWs sought treatment, and how this changed during the pandemic.

Methods

Five major healthcare institutions provided mental health supports to HCWs across Ontario during the pandemic. Data from May 2020 to March 2022 were collected from 2725 HCW self-referrals regarding referral frequency, main presenting mental health problem and demographic information including ethnicity, gender, age, healthcare setting, profession and whether the HCW had a prior mental health diagnosis or had received prior mental health treatment.

Results

Treatment-seeking HCWs who self-referred predominantly self-identified as female and White. Almost half were nurses, and almost half had received previous mental health treatment; a slightly higher percentage reported a prior mental health diagnosis. Over 60% of the overall sample of HCWs worked in hospitals. The timing of increases and decreases in monthly new referrals roughly aligned with the onset and ending, respectively, of COVID-19 waves. The top five most common presenting problems for treatment-seeking were generalized anxiety/worry symptoms, depression, situational crisis/acute stress response, difficulty with stress/occupational or financial, and posttraumatic stress symptoms.

Conclusion

Ontario HCWs self-referred to access mental health supports during the COVID-19 pandemic. The majority sought treatment for generalized anxiety/worry or depression symptoms. Results of this study may inform system planning for future pandemics, as well as for HCW wellness programs for continued workplace stress in the postpandemic period.

Published: February 2025

This study aims to analyze the implementation of knowledge management systems supported by information technology (IT) in private universities (PTS) in Samarinda. The focus is on the role of IT in managing academic data, fostering learning innovation, and enhancing operational efficiency. The research adopts a mixed-method approach, combining quantitative surveys of students, lecturers, and administrative staff with in-depth interviews with institutional leaders and educators. Survey results reveal that most PTS are still in the early stages of adopting IT-based knowledge management systems, with many relying on manual methods or non-integrated systems. The primary challenges identified include limited technological infrastructure, insufficient digital literacy, and inadequate budget allocation. However, institutions that have implemented web-based IT systems reported significant improvements in academic data management efficiency, such as a 50% reduction in administrative processing time, along with increased user satisfaction. The key recommendations of this study include investing in IT infrastructure, such as upgrading server capacity and internet networks, providing comprehensive training for all users, and strengthening partnerships with technology service providers. These strategic measures are expected to accelerate digital transformation, improve the quality of academic services, and create a more innovative, adaptive, and competitive learning environment. This study highlights the crucial role of IT in enhancing the competitiveness of higher education institutions in the global digital era.

A split-plot field experiment was performed to estimate water stress in maize cultivar PMH-13 which was grown using two different nitrogen levels: N1=150 kg ha-1 and N2=120 kg ha-1, each having four irrigation treatments based on IW/CPE ratios of 2.0 (I1), 1.5 (I2), 1.2 (I3) and 1.0 (I4), respectively. In the present study, three replications for each treatment have been employed to examine the impact of various irrigation treatments and nitrogen application on crop stress and yield. Among the four irrigation treatments, I4 exhibited the highest SDD, whereas I2 had the lowest value. Higher frequency of irrigation in I1 and I2 resulted in a reduction of crop stress due to the maintenance of higher soil moisture. Nitrogen application increased yield and reduced SDD. Thus, the irrigation strategy with IW/CPE ratio of 2.0 with nitrogen application of 150 kg ha-1 is observed to be most appropriate to reduce stress and maximize the yield of PMH-13.

The efficiency of using in situ and ex situ technologies for conserving the gene pool of rare highland Gentiana L species (Gentiana lutea L., Gentiana punctata L., Gentiana acaulis L.) has been studied.
The introduction of the conservation regime does not fully provide the stabilization of specimens in the populations of the given species as well as the restoration of their natural habitat.
This is caused by a number of factors: long pastoral load, recreation, plant gathering (picking and digging up); the recent strengthening of the reserve-generating successions because of highland livestock farming husbandry decay; transformation of miscellaneous-cereal groups into firm bunchgrass secondary cenoses; increased projective shrubs coverage of Duschekia viridis (Chaix) DC, Juniperus sibirica Bugsd and Pinus mugo Turra in highland groups; climatogenic changes causing thermal regime change and shifting of plant zones to higher hypsometric levels.
Viability and reproduction of Gentiana species in ex situ collections depend on thermal and ombro-regimes, chemical composition of soil, intensity of solar insolation and light spectral composition to meet the natural needs of the species. If the mentioned factors are inappropriate for the ecological and physiological needs of the species, it is difficult to get viable collections of plants ex situ.
Using in repatriate projects the planting material obtained in ex situ conditions different from natural habitats of the species causes 50 % loss of the specimens in the first years of their vegetation.

Legacy and modern-day ablation codes typically assume equilibrium pyrolysis gas chemistry. Yet, experimental data suggest that speciation from resin decomposition is far from equilibrium. A thermal and chemical kinetic study was performed on pyrolysis gas advection through a porous char, using the Theoretical Ablative Composite for Open Testing (TACOT) as a demonstrator material. The finite-element tool SIERRA/Aria simulated the ablation of TACOT under various conditions. Temperature and phenolic decomposition rates generated from Aria were applied as inputs to a simulated network of perfectly stirred reactors (PSRs) in the chemical solver Cantera. A high-fidelity combustion mechanism computed the gas composition and thermal properties of the advecting pyrolyzate. The results indicate that pyrolysis gases do not rapidly achieve chemical equilibrium while traveling through the simulated material. Instead, a highly chemically reactive zone exists in the ablator between 1400 and 2500 K, wherein the modeled pyrolysis gases transition from a chemically frozen state to chemical equilibrium. These finite-rate results demonstrate a significant departure in computed pyrolysis gas properties from those derived from equilibrium solvers. Under the same conditions, finite-rate-derived gas is estimated to provide up to 50% less heat absorption than equilibrium-derived gas. This discrepancy suggests that nonequilibrium pyrolysis gas chemistry could substantially impact ablator material response models.

Myofascial Pain Syndromes: Controversies and Suggestions for Improving Diagnosis and Treatment

Myofascial pain syndromes (MPS) affect a significant portion of the population. However, they remain controversial because their etiology, diagnostics, and effect mechanisms rely on theoretical frameworks with limited scientific rigor. This viewpoint highlights three main challenges and proposes solutions: First, diagnosis lacks consistent criteria and they are at risk of verification and incorporation biases. Tightened diagnostic criteria and differentiating myofascial pain syndrome from competing conditions will improve accuracy in research and clinical practice. Second, the etiology/pain mechanisms are poorly understood, with symptoms overlapping other conditions. We recommend recording of standardized assessments in national registries including psychological stress and systemic factors to identify distinct phenotypes. Third, the mechanisms behind treatments such as myofascial release and acupuncture are unclear. We advocate for mechanistic clinical trials to uncover how these treatments exert effects. Addressing these challenges will enhance understanding, diagnosis, and treatment of MPS and guide policymakers to fund appropriate research.
“From Time to Time, Being Drunk, He Committed Petty Thefts”: Crimes of Lower-Ranking Military Men of the Vyborg and Kexholm Garrisons in the 1710–1740
Authors: Proskuryakova M. E.
Published: February 2025

The article examines military law and law enforcement in military courts in Russia during the 18th century. The author compares state legislation with sentences imposed on the garrison personnel of the Vyborg and Kexholm fortresses.

The study spans the period from the 1710s to the 1740s, which represents the early use of two pivotal military law acts from the Petrine era: the Military Procedure Code and the Military Article, both issued in 1715. By analyzing archival documents pertaining to the Vyborg and Kexholm garrisons, the author identifies the most prevalent crimes committed by lower-ranking personnel, assesses the nature of the sentences rendered, compares punishments for similar offenses, and traces the application of military criminal law in routine judicial practice. The findings indicate that the most common offenses among lower-ranking members in Vyborg and Kexholm included escapes and thefts. Military personnel were also frequently charged with poor performance of their duties and excessive alcohol consumption.  In contrast, more serious crimes, such as false denunciation, attempts on life, and sexual violence, were relatively rare. Under the law, even minor military offenses faced severe penalties. However, the revision process introduced significant modifications to the nature of these sentences. The College of War frequently reviewed the decisions made by regimental courts, often opting for lighter punishments. Consequently, alongside the established codified norms, a set of unwritten rules emerged that were implemented in practice and tended to be more lenient.
“The Most Important of Cinema for Us Is Art”: The Social Significance of the Activities of the “Sigma” Film Club in Novosibirsk Akademgorodok (1960s – 1980s)
Authors: Zaporozhchenko G. M.
Published: February 2025

The Soviet cities of science of the 1950s – 1980s are now studied as vibrant environments that encapsulate various social and cultural contexts. The article examines, for the first time, the history of the “Sigma” film club in Novosibirsk Akademgorodok. The club gained considerable fame throughout the USSR and continues to function today, albeit  in a more intimate format.. The methodological approach taken in this analysis combines modernization theory, new political history, and social anthropology. This synthesis enables a comprehensive understanding of the history and socio-political significance of amateur leisure socio-cultural practices in the context of the relationship between power and society during the late Soviet period and conditions that led to its unexpected collapse during the period of Perestroika. The principles guiding the organization and activities of the “Sigma” film club identified it as a gathering of engaged individuals rather than merely a venue for film screenings. In addition to showcasing elite films, the club cultivated a communicative environment that facilitated significant cultural events. By promoting the exchange of information and ideas characterized by a distinct ethical focus, the cinema club subculture contributed to the formation of small but genuine enclaves of a pluralistic society, thereby indirectly contributing to the dismantling of the ideological shell of late socialism.
