Published: December 2024

Gymnastics is one of the most popular sports. It occupies one of the most important places in the system of physical education of various categories of the population. This discipline is included in the training programs of school and preschool children, students of higher educational institutions, therefore it has great practical importance. Such a discipline as “Gymnastics with teaching methods” is presented in the State Assessment Tests for Physical Fitness of Various Categories of the Population. Physical fitness tests for schoolchildren are based on athletics exercises and gymnastics exercises. Thanks to gymnastics, we can widely and versatilely give loads from different types of exercises, and this gives us the opportunity to offer and use gymnastic exercises with people of different categories and ages. Performing many gymnastic exercises does not require special facilities and opportunities. The convenience of dosing the load and the positive effect on the entire body have allowed many gymnastic exercises to be included in the programs of secondary schools, in the curricula of colleges, universities, as well as in the programs of youth sports schools and even in exercise therapy - classes with the elderly.

Authors: Nadjar Sarra Ismahane  , Mazouz Said
Published: December 2024

The aim of this article is to study the influence of urban form in different collective housing programs across three neighborhoods in the city of Oum El Bouaghi on user practices and social interactions. To understand the complex relationships and socio-spatial structure of neighborhoods, it is important to use mixed methods. This research is based on a combi-nation of two approaches: qualitative and quantitative. The latter is based on the space syn-tax method, using dedicated software called DepthMap©, specifically applying the visibility graph analysis (VGA). The qualitative approach is based on in-situ observation (static snap-shot method). The observation data from three neighborhoods were collected and synthesized on a map to superimpose them on that of the VGA. The results obtained from correlating observed social activities with syntactic measures show that urban form affects the use of outdoor spaces and can be considered a determining factor in social practices and interactions.

Authors: Ali Fathilah binti , Mohamad Firdaus Omar
Published: December 2024

Sulfur element has been highly sought by many industries everywhere around the world for various applications. This exceptionally useful element has been largely manufactured especially in its powder form each year by different countries and regions with a tremendously increasing manner â€“ reflecting its increase in demand in line with technological advancement and uses for various product applications. The manufacturing processes include mining as well as chemical reactions in Claus Process. Rubber industries normally use abundance of sulfur in their latex compound to introduce vulcanization. Often issues associated with rubber vulcanization specifically includes its dispersibility in the rubber matrix due to improper optimization of its preparation process prior to latex compounding. Another crucial issue is crystallization of soluble sulfur from its insoluble origin, either during or post-rubber vulcanization that constitutes to formation of sulfur bloom that grows on the surface of the rubber articles. It is know that both issues are related to the process conditions and compounding recipe that not impossible to be solved. Various studies have been conducted to at least minimize such occurences â€“ from process optimization to sulfur chemistry itself â€“ and of continuous improvement and innovation to solve various threats in sulfur applications.

Published: December 2024

This project focused on the development of polysaccharides hydrogels from Konjac Glucomannan (KGM) and Xanthan gum in removing the bacterial load on wound. This new therapy design is due to the traditional wound care methods using antibiotic and normal hydrogel cannot adequately treat biofilm infected wounds to healing process. For the treatment of bacterial infected wound, bacterial removal need to be done physically and manually by debridement, which is very painful and require the use of general anesthesia. Therefore, to reduce the formation of slough and necrotic tissue by the formation of bacterial biofilm, there is a need of specific hydrogels that will able to remove bacterial from the wounded site so it will prevent further infection and enhance the healing process. This study focused on the design and optimization of polysaccharide based hydrogels for the wound treatment. Polysaccharide based hydrogels from Konjac Glucomannan (KGM) and Xanthan gum were developed at  different ratio to optimize the physical and chemical properties of the hydrogel that relate to the effectiveness of bacterial removal. Film casting technique was used in the development of the hydrogel film. Konjac Glucomannan (KGM) and Xanthan gum were selected because of their natural polymers properties which are non – toxic, biocompatible and safe to be used. The hydrogels were tested in vitro for bacterial removal efficacy, using E.coli species colonies cultured on a gel inside a petri dish to represent the condition of bacteria infested wound bed. Hydrogel with 50 : 50 % composition blend of KGM-XG was found to be the most effective in the removal of E.coli colonies with 13x103 CFU/mL at 95% water content. Morphological studies of hydrogels showed flat interfacial morphologies, except the sample with 100% of Xanthan without KGM. The results present in this study suggested that the biological activities and adhesion of the hydrogels were not controlled only by the chemical structure but also the composition of compound and the amount of water present in the hydrogels.

Authors: Pairon Mohammad Shahrizad , Ali Fathilah binti , Anuar Hazleen
Published: December 2024

Plastic composites are suitable materials in the production of a cosmetic patch. It can be used as a matrix to hold the fiber in the composites. The fiber used in the cosmetic patch is an active ingredient that has a good reaction in the skin. However, the plastic material gives irritation and allergic when contacting the skin. Hence, the usage of biodegradable plastic such as Polylactic acid (PLA) replaces the conventional plastic in the plastic composites of the cosmetic patch. PLA has a slow degradation rate, therefore the natural fiber (spirulina and alginate) were used to increase the degradation rate of PLA. The objectives of this project were to study the mechanical properties of the PLA composites, the degradation rate of the PLA composites and to characterize the surface morphology and surface properties of the degraded PLA composites. The selection of the best PLA composites is by the highest Young’s Modulus and Elongation at break value. The samples were then left for microbial degradation. The biodegradability results showed that the spirulina enhanced microbial degradation. However, microbial degradation was not the best degradation method since the disturbance of alginate as a binding agent in the soil give an inconsistent result. Scanning Electron Microscopy images showed that the fiber initiates the degradation in the PLA composites.

Published: December 2024

Lactic acid has been a great interest to many industries such as food and beverages, cosmetic, chemical and pharmaceutical due to its various functions. Lactic acid can be produced by fermentation of Rhizopus sp from various substrates such as glucose, starch and lignocellulosic materials. To our knowledge, classification of studies according to the substrates used in the fermentation medium has never been conducted. The main objective of this study is to classify the earlier works on lactic acid production by Rhizopus sp on the most studied substrates. This study also to identify the location or country that focuses on lactic acid production from raw starchy-materials. In this study, a mapping literature study was conducted to classify and structure relevant empirical studies into the types of substrates used. Network visualization based on keywords co-occurrences from selected bibliographic databases is included in this study as well. Eleven (11) substrates were identified from 171 empirical studies. Thirty-two (32) studies were discovered to use starch as substrates in lactic acid production by Rhizopus sp. Out of 32 studies, only twelve (12) studies reported of using raw starchy-materials in their studies where most of the studies were reported from United states. This study redounds to the researchers to uncover critical areas in the production of lactic acid especially in the use of substrates for novel approaches thus, a new hypothesis can be made.

Propolis produced by stingless bees has a high economic value in Indonesia. Bukit Sandy is a plantation area in Cimenyan, Bandung which is famous for citrus picking tourism and has the potential to be developed for meliponiculture. Currently, there are stingless bee colonies in Bukit Sandy, but the colonies are not growing well. This research aimed to examine environmental conditions and techno-economic analysis of meliponiculture in Bukit Sandy. This research used descriptive analysis, vegetation analysis, colony carrying capacity analysis, and techno-economic analysis methods. Based on the environmental description, conditions of the environmental in Bukit Sandy are suitable for meliponiculture. Dominant forage vegetation potential for stingless bees in Bukit Sandy are mahogany (tree), pine (pole), lemon (sapling), and paspalum (seedling). The estimated potential for production of honey in Bukit Sandy ranges from 2.25-30.21 kg/month and the carrying capacity of stingless bee colonies in Bukit Sandy is 4-54 colonies. This study proposed several scenarios for techno-economic analysis for cultivation of Heterotrigona itama; i) 4 colonies with raw propolis and honey as products, ii) 4 colonies with propolis extract, honey and propolis residue as products, iii) 4 colonies with raw propolis and honey as products, ii) 54 colonies with propolis extract, honey and propolis residue as products. Based on the techno-economic analysis, meliponiculture in Bukit Sandy is technically feasible and profitable for scenario 2 and 3, while scenario 1 is not profitable. Scenatio 2 is proposed for early stages of meliponiculture in Bukit Sandy and later transformed to scenario 3 for higher profit and benefits to the society

Published: December 2024

The hybrid system of microbial electrolysis cell (MEC) and anaerobic digester (AD) has been a promising approach for sustainable energy production and waste treatment. The integration of MEC and into the AD digester offers multiple advantages over conventional AD systems. The study was conducted on the modification of carbon felt (CF) anode, and stainless-steel mesh (SSTM) cathode with multi-wall carbon nanotubes (MWCNT), to facilitate the biomethane production and upgrade within the hybrid system. The microbial attachment to the electrodes was analyzed, the substrate concentration, current density, and biogas composition and volume were monitored. The SEM imaging of the electrodes showed that the microbes followed a different growth behaviour in modified and unmodified electrodes. In addition, MWCNT modified SSTM showed a potential hydrogenotrophic growth selectivity, unlike unmodified SSTM, which had a more syntrophic microbial community. Stainless steel mesh-modified cathode showed the highest biogas and methane production with a value of 14.4 ml CH4/g glucose. In addition, the carbon-felt modified electrodes showed a maximum substrate degradation value of 93% and a current density of 4.5 mA/m2.

Published: December 2024

Malaria cases have increased globally, which is due to the emergence of zoonotic malaria parasites that infect human, along with the existence of artemisinin-resistant parasites. Hence, there is an urgent need to find new therapeutics to counter these issues. As a vital enzyme in the glycolytic pathway that serves as the parasite's primary energy source during its intraerythrocytic stage in human, lactate dehydrogenase from Plasmodium knowlesi (Pk-LDH) can be a potential drug target. This project aims to screen for existing natural products that have progressed to preclinical or advanced drug development phases against Pk-LDH via ligand-based virtual screening (LBVS) and to evaluate the potentials of these bioactives as repurposed drugs by binding energy estimation through structure-based virtual screening (SBVS). The LBVS method, which was conducted via LiSiCA and ChemMine, are based on shape-based molecular similarity calculations to screen for analogues of the query molecules, which are lactate and pyruvate. Subsequently, PyRx simulation software were utilised for docking studies with the aid of PyMOL and PLIP software. This study discovered that Compound 7, ?-hydroxyisovaleric acid, and Compound 2, alpha-ketoisovalerate are structurally similar to compounds that directly involved in the metabolic pathways of P. knowlesi, lactate and pyruvate, with a similarity score of 0.75. Both compounds also formed strong interactions with Pk-LDH, resulting in strong binding affinities of -4.6 kcal mol–1 and -4.3 kcal mol–1, respectively. These findings open possibilities for using natural products in drug repurposing as anti-malarial agents.

Published: December 2024

Selangor, like many other Malaysian states, experienced various disruptions due to the pandemic. In addition to health and economic challenges, the populous state also faced notable issues regarding waste production. The COVID-19 pandemic has led to a dramatic rise in solid waste generation especially in its two largest sources, municipal solid waste (MSW) and clinical solid waste (CSW). The pandemic resulted in people staying at home and relying on home deliveries, which led to an escalation in MSW. Healthcare workers also faced longer hours due to the growing number of COVID-19 patients, causing increased production of CSW. Though, it is unclear which waste source is more affected by the pandemic. In the present study, the trend of solid waste generation in Selangor during the pandemic was investigated. A comparison was also made between the annual generation rates of both MSW and CSW, particularly spanning the period from 2019 to 2021. After collecting relevant numeric data from respective resources, the data is recorded into Microsoft Excel to generate graphs. The findings showed that in 2019, Selangor witnessed a generation of 1,358,786 tonnes of MSW, which increased to 1,426,551 tonnes in 2020, and further escalated to 1,484,282 tonnes in 2021. As for CSW, Selangor generated a total of 7,343 tonnes in 2019, 9,703 tonnes in 2020, and 12,993 tonnes in 2021. The analysis uncovered that MSW exhibited an average annual generation rate of 4.5%, whereas CSW demonstrated a higher average generation rate of 33%. An upward trend was seen in both MSW and CSW generation in Selangor from 2019 to 2021, with CSW demonstrating a significantly higher generation rate.

Published: December 2024

The relevance of this study was to investigate the impact of abiotic stress, specifically fullerene C60 and drought, on the morphometric characteristics of pea microgreens. Drought negatively affects the growth and development of agricultural plants, leading to reduced yields. Carbon nanoparticles, particularly fullerene C60, due to their unique physical, chemical, and biological properties, may serve as modulators of resistance to stressful conditions such as drought, enhancing the physiological and biochemical processes at both the cellular and whole plant levels. This research aimed to investigate the effect of fullerene C60 on the morphometric parameters of microgreen peas (Pisum sativum) of the ECO variety under water deficit conditions. Structured water-soluble carbon nanoparticles of fullerene C60 were employed. C60 molecules were transferred from an organic solution into the aqueous phase, followed by ultrasonic treatment. The morphometric indicators evaluated in the microgreen peas included shoot height, shoot diameter, number of leaves, leaf weight, plant weight, and root length. The experiment was conducted on the 14th day after treating pea seeds with an aqueous solution of fullerene C60 at concentrations of 0.1, 0.2, 0.5, and 1.0 g/mL with planting in substrates of both linen mats and a soil mixture. Chemical, physical, and physiological methods were employed. Fullerene C60 at the given concentration range (0.1-1.0 g/mL) did not exhibit negative phytotoxic effects on pea microgreens. Moreover, the drought-induced physiological state of the microgreens was restored by pre treatment of the seeds with the fullerene C60. The results demonstrated the absence of phytotoxic effects and confirmed the protective effects of fullerene C60 against drought stress in pea microgreens, suggesting the potential of using structured carbon nanoparticles in agrobiotechnologies to regulate stress resistance mechanisms in crops

The aim of this article is to explore the features of the educational process in the Kyiv Theological Seminary during the second half of the 19th century and the early 20th century. The authors examine the fundamental principles of the functioning of a secondary educational institution of the Russian Orthodox Church. The research methodology is based on the principles of historicism, objectivity, and systematics. First of all, general scientific methods of historical knowledge—analysis, synthesis, and systematic analysis—are employed. Scientific novelty. The educational process at the Kyiv Theological Seminary during the late 19th and early 20th centuries is analyzed as an integral part of the spiritual education system of the Russian Empire on the Ukrainian lands. The study demonstrates the Russification-oriented nature of this process. Conclusions. The theological seminaries were a significant component of spiritual education in the Russian Empire, designed to train clergy as leaders of the imperial ideology within society. The Kyiv Theological Seminary was an integral part of this system, without any particular distinguishing features compared to other seminaries across the Empire. In the second half of the 19th century, a deliberate process of unification and centralization in the educational sphere was underway, with the 1867 and 1884 Seminary Statutes playing a crucial role. The educational process, as well as the overall activities of the Kyiv Theological Seminary, were strictly controlled by the Educational Committee of the Holy Synod. The curriculum was highly regulated and structured. Seminary students were under constant supervision by their instructors, ensuring their loyalty, if not devotion, to the Russian imperial regime. Graduation from the Kyiv Theological Seminary provided access to admission to the Kyiv Theological Academy, but only 1% of seminarians  chose to continue their studies there.

Published: December 2024

The purpose of the article is to determine, based on the analysis of the statistical materials of the 1926 population census, the ethnic composition of village councils and the rural population of Eastern Podillia, namely Vinnytsia, Mogilev, and Tulchyn districts, and to establish the proportionality of the representation of ethnic groups in village councils to their overall share among the rural population. The research methodology is based on a combination of general scientific (analysis, synthesis, deduction) and special-historical (historiographical scientific analysis, structural-systemic) methods with the principles of historicism, objectivity, scientificity, evidence, and the statistical method of research is also involved. The scientific novelty of the work lies in the fact that on the basis of archival materials and the analysis of statistical data of the 1926 census, a comparative analysis of the ethnic composition of the rural population in all three districts of Eastern Podillia was carried out, and on the basis of the obtained statistical data, common features and differences in the ratio of the share of Ukrainians and ethnic minorities were established among the rural population as a whole and members of village councils in Vinnytsia, Mogilev and Tulchyn districts. Conclusions. According to the population census in 1926, the ethnic composition of the rural population and village councils of Vinnytsia, Mogilev and Tulchyn districts had a number of common characteristics. In particular, Ukrainians made up the absolute majority both in village councils and among the rural population, and the indicators in all three districts are almost identical. As for the ethnic minorities living on the territory of Eastern Podillia, their share was insignificant, both among the population and in village councils. As for the ratio between the share of each ethnic group among the rural population and village councils, the data are almost identical, the difference between them is small and fluctuates within the limits of statistical error.
Релігійна політика нацистів на теренах окупованого Поділля

Published: December 2024

The purpose of the article is is a reproduction based on the analysis of a number of sources of the real picture of religious life in Podillia during the Nazi occupation of the region during World War II, highlighting the problem of the situation of the church and believers in the German occupation zone, revealing the true essence of the occupation authorities' use of religion as an effective mechanism for implementing their own occupation policy.The methodologe of the research is based on a combination of general scientific (chronological, problem-historical, analytical, synthesis, generalization) and special-historical (historical-topological, historical-systemic) methods with the principles of historicism, objectivity, systematicity, scientificity, and verification. Scientific novelty of the work is that, using these methods, based on the publication of a number of little-known archival and other sources, the author reveals the real essence of the religious policy of the Hitlerite invaders in the Ukrainian regions occupied by them, in particular, in Podillia. Conclusions. To implement the occupation policy in the occupied territories of Ukraine (Podillia) in order to strengthen the influence on the local population, the Nazis used the religious factor. The Nazis considered the church an important weapon in the fight against Bolshevism, since the restoration of religion, which was actually illegal in Soviet times, was supposed to demonstrate to the local population the "adherence" of the new government to it. The invaders tried to prove that with their arrival, Ukrainians had gained the religious freedom lost during the communist regime. By legalizing the church, the occupation authorities contributed to its split into the Ukrainian Autocephalous Orthodox Church and the Autonomous Orthodox Church. The struggle between the church camps only played into the hands of the occupation authorities. The occupation authorities also had a biased view and influence on other religious denominations. Relative freedom of religion soon became a thing of the past. Control over religious organizations was noticeably strengthened. During 1941-1944, the religious policy of the occupiers focused on securing the interests of the Third Reich and was one of the most speculative in their propaganda and agitation work. At the same time, the spiritual needs of the population were practically not taken into account.
Effect of nano-calcium carbonate on mechanical properties of interfacial transition zone between fiber surface and concrete
Authors: Phi Dang Van , Thuong Ngo Tri
Published: December 2024

This study investigated the effect of nano-CaCO3 content on the hardness (H) and Young’s modulus (E) at the interfacial transition zone (ITZ) surrounding fibers and ultra-high performance concrete (UHPC). Nano-CaCO3 was incorporated at varying contents from 1% to 4% by weight of cement. The nanoindentation (NI) test and scanning electron microscopy (SEM) to examine the mechanical properties and microstructures at the ITZ. The results of the study indicated that UHPC incorporating nano-CaCO3 exhibited an improvement in both H and E at the ITZ compared to UHPC without nano-CaCO3. Specifically, the H and E values for UHPC containing 3% nano-CaCO3 were measured at 3.49 ± 0.15 and 51.47 ± 1.23 GPa, respectively, whereas those values of UHPC without any nano-CaCO3 were 3.10 ± 0.12 and 49.44 ± 1.22 GPa, respectively. This enhancement in H and E at the ITZ is attributed to the toughening effects at the interface caused by the nano-CaCO3, along with improved hydration. Besides, SEM images revealed that UHPC containing nano-CaCO3 displayed a denser and more homogeneous microstructure compared to its counterpart without nano-CaCO3. Furthermore, the addition of nano-CaCO3 increased the compressive strength of UHPC by 1.47% to 9.49% as the content rose from 1% to 4%, attributed to improved particle packing and a more compact microstructure. In contrast, UHPC flowability declined as nano-CaCO3 content increased, as indicated by a reduction in slump flow from 185 ± 15 mm to 160 ± 5 mm, which is associated with increased water absorption by the extensive surface area of the material.

Assessment of individual behavioral characteristics (IBC) of domestic dogs is of both fundamental and practical interest to researchers. The paper presents the results of developing and assessing the reliability of a methodology for assessing IPC based on an online survey of owners who do not have special training. 4530 respondents took part in the survey. The questionnaire included 20 questions, which were rated on a Likert scale. Using the factor analysis method, 6 factors were identified, by which the IPC of different breed groups was compared according to the FCI classification, and the prognostic role of breed in determining differences in the IPC of dogs was assessed. A comparison of the data from our questionnaire with similar ones obtained in the USA and Japan (Q-BARK) showed that the identified factors generally coincided (Cronbach’s Alpha was 0.73, which indicates sufficient reliability of the methodology), although the questions for the Russian audience were formulated differently. Thus, this questionnaire can be used to assess the IPC, the formation of a modern behavioral portrait of a particular breed, its compliance with existing standards, as well as changes that occur as a result of the lack of selection, for example, for working qualities.

The paper explores the possibilities of using data classification methods when forecasting time series of the geomagnetic Kp-index by machine learning methods. To classify categories of the Kp-index based on the degree of disturbance, linear and logistic regression, random forest, gradient boosting on top of decision trees, and artificial neural networks of various architectures are used. The results of these methods are compared with a trivial inertial forecast (the statistical indicators of which for problems of this type are always high) at horizons from 3 h to 1 day in 3-h increments. The problem of choosing a cross-validation scheme for selecting the model hyperparameters, ways to overcome the imbalance of categories, the relative importance of input features, as well as the dependence of the results on the test sample (beginning of the 25th solar activity cycle) on inclusion in the training sample of data from the 23rd and 24th cycles or only the 24th cycles are studied. Based on the results, conclusions are drawn about the preferred methods for classifying values of the Kp-index based on the level of geomagnetic disturbance. Ways for further research and possible improvement of the classification quality are outlined, including for determining the characteristic hidden states of Earth’s magnetosphere as a dynamic system in order to improve the quality of forecasting geomagnetic indices.

The stress diagram of polymer composite material based on PDI-3A rubber filled with thermally expanded graphite or potassium chloride before and after microwave treatment for 300, 600, 900 and 1200 s has been studied. A twofold increase in tensile strength and deformability was found after microwave treatment for 300 c and testing at 223 K. With increasing the test temperature or microwave treatment time, a marked decrease in the deformation and tensile strength characteristics of the obtained composites was observed.

Laser material Y3Al5O12 (YAG), originally known in the form of a single-crystal, has been distributed and widely commercialized in the form of optical ceramics. The desire to expand the functionality of materials made of nanocrystals due to the size effect actualizes the study of the influence of their structure on the optical (vibrational and electronic) and other properties of new promising materials with the YAG base including glass ceramics. In this work, models of crystalline alumina-iodine garnet fragments have been calculated by DFT/uPBEPBE/SDD, DFT/uPBEPBE/lanl2DZ, and DFT/uB3PW91/SDD methods. The IR spectra were calculated by DFT/uPBEPBE/lanl2DZ method and the absorption bands of the calculated wave numbers were correlated with the measured ones. The electronic absorption spectrum and energy levels were calculated by the DFT/RB3PW91/SDD method.

Published: December 2024

The radiolysis of liquid and boiling hexafluoroacetylacetone was studied. The structure of the main radiolysis products indicates the predominance of C–CF3 and C–F bond cleavages. Ten compounds are formed, including monoketones, trifluoroacetic acid, keto alcohols, and tautomeric tetraketones. Carbon monoxide is the main gaseous product and its yield increases under boiling conditions. The initial yield of hexafluoroacetylacetone degradation is 0.29 ± 0.2 and 0.32 ± 0.2 µmol J-1 at 293 and 343 K, respectively. No accumulation of free HF is observed at low doses. The products of radiolysis are less diverse than in acetylacetone, which is due to the increased “cage” effect, the increase in the Onsager radius and the ability of trifluoromethyl groups to dissipate excitation energy.

A method has been developed for manufacturing biological microchips on an aluminum substrate with hydrophilic cells from brush copolymers with the formation of a matrix of cells using photolithography. The surface of aluminum substrates was previously coated with a thin, durable, moderately hydrophobic layer of cross-linked polymer to prevent contact with the aluminum surface of the components used in the analysis of nucleic acids. Aluminum biochip substrates have high thermal conductivity and low heat capacity, which is important for the development of methods for multiplex PCR analysis on a chip. Oligonucleotide probes were covalently immobilized in the cells of the biochip. The preservation of the hybridization activity of the immobilized DNA probes was demonstrated in a hybridization analysis with a synthetic DNA target representing a section of the sequence of the 7th exon of the human ABO gene. The developed methods can be used in the development of a technology for parallel multiple rapid microanalysis of nucleic acids “lab on a chip” for the detection of human somatic and infectious diseases

Published: December 2024

We studied the activity of energy and carbohydrate metabolism enzymes (cytochrome c oxidase, lactate dehydrogenase, glucose-6-phosphate dehydrogenase, 1-glycerophosphate dehydrogenase, pyruvate kinase, aldolase) in the muscles and liver of rainbow trout of three size groups aged 5, 10 and 12 months under the influence of two types of commercial feeds with different composition. The levels of activity of the enzymes G6PDH, 1-GPDH and aldolase in the liver were significantly higher in fish from the “Feed №2” group. The identified differences in the activity of enzymes in the liver of fish suggest that feed №2 to a greater extent (compared to feed №1) promotes the use of carbohydrates in lipid biosynthesis. Differences in the activity of the enzymes COX, LDH, aldolase, G6PDH and 1-GPDH in the liver and muscles of fish depending on the month of sampling and belonging to the size group are most likely associated with changes in the metabolism of fish as their weight increases towards generative metabolism.

Published: December 2024

A study was carried out of the yield and elements of the productivity structure of 32 varieties of hexaploid triticale of various origins from the world collection of VIR. The work was carried out at the Dagestan OS – a branch of VIR, located in the southern flat zone of the Republic of Dagestan. For a comparative study, wheat varieties Nika Kubani and Tanya were used. The study showed that the studied triticale varieties exceeded wheat varieties in terms of such characteristics as: yield, ear length, number of spikelets, grains and grain weight per ear and 1000 grains. However, according to some indicators that determine potential yield, triticale is inferior to wheat – the number of productive stems and the number of grain-free flowers per ear. Based on a complex of economically valuable traits, triticale varieties were identified: PRAGi – 494, 415/3, 479, 468, 483/1, 470/1 and 473/2 (Dagestan), Presto 401 (Poland), Newton (France), TSW 2507 (Germany), which can be recommended as a source material in practical breeding work when creating new varieties with high productivity.
