Authors: Kurniawan Guruh Kristiadi , Devita Citra , Akbar Muhammad Arya Guna
Published: July 2024

Abstract: Public spaces are often considered merely as facilities that provide space for user activities/interactions, resulting in minimal awareness regarding the maintenance and supervision of the available space. In its formation, public spaces must also support sustainability in each of its elements that link environmental aspects (space) with social aspects (users) to fulfill needs and complement each other. In response to this, PKOR Way Halim as a provider of public space needs to be analyzed to make adjustments in accordance with sustainable public space criteria. The method employed is a qualitative descriptive method focusing on behavior patterns through behavior mapping, which is then analyzed by elaborating on the understanding related to sustainability. Thus, the results indicate that PKOR Way Halim as a provider of public space does not yet meet the "sustainability" criteria. This is due to the social aspect, namely user behavior patterns, which significantly influence a space. User awareness is crucial to encourage movement patterns in activities that shape sustainable public spaces.Keyword: behaviour mapping, sustainability, behavior patterns, public spaceAbstrak: Ruang publik sering kali dianggap hanya sebatas fasilitas yang menyediakan ruang untuk suatu aktivitas/interaksi pengguna, sehingga minim sekali kesadaran dalam hal pemeliharaan dan pengawasan terhadap ruang yang tersedia. Dalam pembentukannya, ruang publik pun harus mendukung adanya keberlanjutan pada setiap elemennya yang mengaitkan antara aspek lingkungan (ruang) dengan aspek sosial (pengguna) agar kebutuhan terpenuhi dan saling melengkapi. Untuk menanggapi hal tersebut, PKOR Way Halim sebagai penyedia ruang publik perlu dianalisis agar memenuhi penyesuaian dengan kriteria ruang publik berkelanjutan. Metode yang dilakukan berupa metode kualitatif deskriptif terhadap pola perilaku melalui behaviour mapping yang kemudian dianalisis dengan penjabaran mengenai pemahaman terkait keberlanjutan. Sehingga, hasil yang didapat bahwa PKOR Way Halim sebagai penyedia ruang publik masih belum memenuhi keriteria “keberlanjutan”. Hal tersebut didapat karena adanya aspek sosial berupa pola perilaku pengguna yang sangat berpengaruh terhadap suatu ruang. Kesadaran pengguna sangat dibutuhkan untuk mendorong pola pergerakan dalam berkegiatan yang membentuk ruang publik yang berkelanjutan.Kata Kunci: behaviour mapping, keberlanjutan, pola perilaku, ruang publik

Published: July 2024

A new occurrence of phosphate mineralization – named Shankinka – has been explored in the mouth of the Fed’kovskaya river in the Ruza District of the Moscow region, of which, the most common mineral phases include delvauxite, mitridatite, fluorapatite and crandallite. It has been established that all the Fe-Ca-Al phosphates occurrences in the region are associated with the Bajocian-Bathonian paleovalleys embedded in the Carboniferous rocks and partially filled with Callovian sediments. The structural features of the phosphatization zone as well as its enrichment with Co, Ni, Zn, Cu, and REE indicate a possible link between the Oxfordian organic-rich sediment and phosphate mineralization. It can be assumed that epigenetic phosphate mineralization was a result of the seepage of phosphorus-rich pore waters released from the Oxfordian organic-rich sediment into the underlying Callovian permeable rocks rich in iron minerals.

This article presents results of the comprehensive study (composition, reservoir properties, geophysical parameters and age) of altered felsic volcanic rocks (rhyolites, dacites) associated with the Permian-Triassic intermediate structural level of the West Siberian. As a result of secondary alteration, oil and gas reservoirs can form in these volcanic rocks. Taking into account their occurrence depth (more than 2 km), they are available for study only from core and geophysical data. Based on the results of core studies, 25 petrographic varieties of felsic volcanics were established. The combination of such features as 1) structural and textural features, 2) degree of secondary alteration, and 3) peculiarities of logging curves made it possible to group these numerous petrographic varieties into six key rock types. At the same time, the distinguished rock types are characterized by different reservoir properties (porosity, permeability). All 443 samples representing various rock types are characterized by similar geochemical composition, and the U-Pb ages obtained by the zircons (254 ± 2–248.2 ± 1.3 Ma) indicate that the studied felsic volcanics belong to a single tectonic-magmatic stage at the Permian-Triassic boundary. According to seismic data, it was revealed that within the Frolovskaya megadepression (the central part of Western Siberia), the studied volcanic rocks are distributed within grabens. In particular, the boundaries of a relatively large (70 km wide and 200 km long) graben-like Rogozhnikov-Nazym structure were adjusted, and several similar, but smaller structures were identified. A comprehensive analysis of core, log and seismic data made it possible to determine the morphology and spatial relationships of volcanic bodies composed of various types of felsic volcanic rocks, providing the basis for predicting intervals of the section with the best reservoir properties.
FERROMAGNETIC RESPONSE OF THIN NiI2 FLAKES UP TO ROOM TEMPERATURES

Published: July 2024

We investigate the magnetic response of thin NiI2 flakes for temperatures above 80 K. Since no magnetic ordering is expected for bulk NiI2, we observe clear paramagnetic response for massive NiI2 single crystals. In contrast, thin NiI2 flakes show well-defined ferromagnetic hysteresis loop within ±2 kOe field range. The value of the response does not scale with the sample mass, ferromagnetic hysteresis can be seen for any flake orientation in the external field, so it originates from the sample surface, possibly, due to the anisotropic exchange (Kitaev interaction). The observed ferromagnetism is weakly sensitive to temperature up to 300 K. If a flake is multiply exposed to air, ferromagnetic hysteresis is accompanied by the periodic modulation of the magnetization curves, which is usually a fingerprint of the multiferroic state. While NiI2 flakes can not be considered as multiferroics above 80 K, surface degradation due to the crystallohydrate formation decreases the symmetry of NiI2 surface, which produces the surface ferroelectric polarization in addition to the described above ferromagnetic one.
Efficiency of the BIOSTIM grain drug usage in the cultivating winter soft wheat technology
Authors: Magomedova D. S. , Kurbanov S. A.
Published: July 2024

In the conditions of the Terek-Sulak lowland of the Republic of Dagestan in 2019–2022 studied the effect of biological products on the yield and grain quality of winter soft wheat varieties selected by the National Grain Center by P.P. Lukyanenko (Thunder) and the North Caucasus Federal Scientific Agrarian Center (Carolina 5). An analytical review of literary sources indicates that the use of new varieties and biological products is an important factor in increasing the yield of grain crops, which ensure the profitability of their use at low costs. To determine the effectiveness of biological products, pre-sowing seed treatment and foliar treatment of crops of these varieties of winter soft wheat carried out. Weather conditions during the years of the experiment were generally favorable. The spring-summer development of plants took place in small differences in heat supply with fluctuations in the hydrothermal coefficient from 0.37 to 0.58. As a result, of four years of research, it established that the productivity of crops depends not only on the variety, but also on the scheme of application of biological products and their combinations. The maximum yield is provided by the Carolina variety 5 – 6.44 t/ha, which is 0.87 t/ha higher than that of the Grom variety. The combination of pre-sowing seed soaking with Potassium Humate Prompter and treatment of wheat crops with the biostimulant Biostim grain provided an increase in grain yield of 0.71 t/ha. Calculation of adaptability parameters showed that the Carolina 5 variety is most adapted to specific soil-climatic conditions and the level of technology used, and in this regard, it may be of practical interest in terms of variety replacement of zoned varieties of winter soft wheat for the irrigated zone of the region.

April 26, 2024 marks 38 years since the accident at the Chernobyl nuclear power plant (1986). In the area of the Chernobyl nuclear power plant, Novozybkovsky district of the Bryansk region, field experiments were carried out to study the accumulation of radiocesium in grain in 42 varieties of winter rye and 92 varieties of winter wheat. In total, for the period from 1987 to 1993. In the contaminated zone of the Bryansk region, 1532 varieties were studied from 28 crops of the world gene pool. The Moscow branch of VIR, as the lead institution, and many other research institutions were involved in the research. The results of studies in the contaminated zone of the Chernobyl nuclear power plant showed that the world plant gene pool has a wide variety of forms for the accumulation of radionuclides. The maximum difference (under the conditions of one year and field) between crops in the accumulation of cesium-137 in grain can reach 170 times, and between varieties within the same crop – 9 times. The eniological approaches presented in the book, which take into account information and energy interactions at different biological levels, can and should be taken into account both in breeding work and in assessing the global plant gene pool.

The production of high-quality dairy products is largely influenced by proper provision of optimal conditions for keeping animals. Properly selected conditions for keeping a dairy herd directly affect the strengthening of immunity, productivity and quality of dairy products. The article provides information about pasture and stall conditions for keeping animals with the advantages of pasture keeping in terms of milk productivity and the quality of raw milk. The features of both content systems are briefly summarized. Pasture is most often used in regions with an acceptable climate; stall – mainly in regions with developed agriculture and with limited opportunities for walking livestock on natural pastures. The results of studies of quantitative and qualitative indicators, as well as the nutritional value of milk obtained from Holstein cows kept under pasture and stall systems in two farms in the Volgograd region are presented. From the resulting raw milk, a brief technology for producing samples of a fermented milk product – kefir with lactulose – is shown. Kefir was produced using traditional technology, using a starter culture of kefir grains. The prebiotic carbohydrate lactulose, which has a proven preventive effect, was chosen as an enriching component. Organoleptic, physico-chemical, microbiological parameters, as well as amino acid composition, were studied in samples of the finished product. The results obtained indicate high levels of nutritional and biological value of raw milk and fermented milk products made from it.

The effect of molecular hydrogen during cryopreservation on the ultrastructures of bovine sperm cells has been studied. The study was performed on the sperm production of black-and-white Holstein bulls. The sperm was diluted with a sterile BioXcell medium (France). To study the effect of molecular hydrogen on the sperm cells of bulls, “BioXcell” diluted with hydrogen water was used. Native sperm diluted with the «BioXcell» diluent, sperm after deep freezing and sperm after deep freezing, pretreated with molecular hydrogen, were studied. The study of morphological parameters of spermatozoa after cryopreservation showed an increase in cells with an anomaly in the structure of the head, chromatin is insufficiently condensed, the content of spermatozoa with an altered position of the acrosome is increased, the ultrastructure of the axoneme is changed, irregular laying of mitochondria is noted. The use of molecular hydrogen as a cryoprotector contributed to an increase in the number of spermatozoa with intact heads having normal acrosomes, shape and chromatin of the nucleus. The results obtained indicate a positive effect of molecular hydrogen on morphological parameters of bovine sperm cells.
Immune status of broiler chickens during different times of physiological development

The widespread prevalence of immunodeficiencies in farm animals challenges researchers to develop a sound and evidence-based methodology for early detection of immune system deficiencies for prevention and timely correction. In this regard, the strategy of modern scientific research is primarily aimed at a detailed study of the immune system, the mechanisms of immunosuppression and the search for effective means of correction of disturbed immune homeostasis. The aim of this study was to investigate the immune profile of healthy broiler chickens during physiological development. Immune status was assessed in broiler chickens of Arbor Acres cross at the age of 7, 14, 28 and 42 days, including determination of serum levels of cytokines (IL-2, IL-4, IL-10, IFN-γ), immunoglobulins (IgA, IgY) and lysozyme by enzyme immunoassay. It has been established that during postnatal ontogenesis the immune system of broiler chickens undergoes dynamic changes, which have an age direction and phase character. The results obtained indicate a decrease in the efficiency of functioning of the immune system of birds with increasing age. The most pronounced immunological deficiency in the organism of broiler chickens is observed at the age of 7–14 days, which is associated with the immaturity of the immune system and is characterized by the fact that nonspecific humoral and specific cellular defense factors are at a rather low level – the level of lysozyme, IL-2, IL-10 and IgA in blood serum at this age was minimal; starting from 28 days of age, there is a specific humoral immune insufficiency, which is compensated by strengthening of cellular defense factors – serum level of IgY intensively decreases against the background of increase of lysozyme, IL-2, IL-4, IL-10. Such changes in the immune system can affect immunocompetence, susceptibility to diseases, and as a consequence, meat productivity.

Mobilization of 1876–1877. The first experience of Imperial Russia
Authors: Airapetov Oleg R
Published: July 2024

After the defeat of the Serbian army on October 29, 1876, near Junis, Emperor Alexander II, after much hesitation, decided to begin mobilizing the Russian army in order to force the Ottoman Empire to conclude an armistice with Serbia. Mobilization caught the army in a period of unfinished transformations. In 1874, universal conscription was introduced, in the same year the Empire's armory factories began producing Berdana rifles, their rearmament in 1877 was not completed. During the first mobilization of the mass army, all this affected the condition and combat capability of the troops. A particularly important and difficult problem was the condition of the railways, besides, the Russian command did not yet have the experience of transferring, concentrating, or supplying such a significant mass of troops by rail. All this had an impact on the war plans and the conduct of military operations beyond the Danube.
Kandalaksha direction in Soviet military planning in 1940–1941
Authors: Mironichev Evgeniy P
Published: July 2024

The article, based on archives’ materials, memoirs and scientific literature, shows the role of the Kandalaksha in the soviet military planning in 1940–1941, which has not been deeply considered in the historiography. The problematic nature of military planning on the Kandalaksha direction in 1940–1941 is revealed. An attempt is made to comprehensively characterize the Kandalaksha direction as one of the most important areas of military operations in the North in 1941. The problem of reflecting the role of Kandalaksha during the Great Patriotic War in domestic historiography, which focuses on the events of the Murmansk direction, is raised.
The Red Army and the disruption of the plans of the German command in the Oboyan direction in the summer of 1943

In the history of the 1943 summer campaign on the Soviet-German front, the initial plans of the Wehrmacht and the Kursk defensive operation of the Red Army, as well as the fighting in the Voronezh Front, have been most studied. However, the final version of Operation Citadel is practically not covered in historiography. The idea of this Wehrmacht operation is usually presented only as counterattacks by two groups concentrated at the base of the Kursk salient, with the aim of encircling the Central and Voronezh fronts. But the 2nd Field Army, commanded by Infantry General V. V., was also to take part in the offensive. Weiss, who occupied the defense in the western part of the Kursk Bulge. Its strike from the west in the direction of Kursk, the junction of the Central and Voronezh fronts, could significantly complicate the situation of the Red Army. The documents found in the German Federal Archive confirm that the German command was counting on such a development of events. By the beginning of the general offensive on Kursk, the divisions allocated to break through the defense were brought to the maximum degree of readiness. A comparative analysis of these materials and Soviet documents makes it possible to understand how, thanks to the unparalleled fortitude and courage of the soldiers of the Voronezh Front, it was possible to paralyze the enemy forces in the Oboyansk direction.
