Bestializados y oprimidos: figuraciones del chiclero en la cuentística campechana del siglo XX
Authors:   Universidad Autónoma de Campeche, Vadillo Buenfil Carlos
Published: September 2024

La extracción de la resina del chicozapote en las selvas de Campeche fue boyante en la primera mitad del siglo XX. Sus protagonistas fueron, por un lado, trabajadores de la península de Yucatán y de estados limítrofes; por el otro, contratistas nacionales y compañías norteamericanas. Los comportamientos de los chicleros han sido ficcionados por cuatro cuentistas campechanos, en igual número de relatos, entre 1952 y 1978: Fausto Vallado Berrón, Joaquín Santella, Juan de la Cabada y Enrique Escalante Escalante. Por las tematizaciones, tramas y representaciones de seres salvajes y sometidos, este artículo analiza los cuentos bajo ciertos aspectos del naturalismo y del criollismo. Estos enfoques teóricos bosquejan el tópico civilización y barbarie, enfatizan la denuncia de la explotación del resinero y visualizan argumentos de combate contra la despiadada selva y la endeble condición humana. La paradoja de los chicleros fue que aportaron mano de obra barata para que unos cuantos se enriquecieran, pero pasaron a la memoria colectiva y a la prosa de ficción como individuos marcados por la ignominia; en suma, como sujetos degradados, temerarios y torvos.

Hyperglycemia and insulin resistance are the two major hallmarks of T2DM, a metabolic disorder that is widely spread and severely threatening global public health. Of interest, treatment options for T2DM are also under significant advancements in the recent past, including medication, bariatric surgery, and lifestyle modifications. In addition, lifestyle therapies, including changes in eating and additional physical activities, substantially improve glycemic control, while pharmacotherapy provides a large number of drugs focusing on different components of the pathophysiology of type 2 diabetes. Besides, over the past years, bariatric surgery has also been proposed as a possible alternative for intractable diabetics with extreme obesity. This paper seeks to shed some light on the changing roles in type 2 DM therapy by now revisiting the current modifications; ultimately, it is targeted at reducing the burden of the disease for improved patient outcomes and enlightening policymakers and healthcare professionals on the same.

Authors: Sedhain Nesuma , Adhikari Shree Prasad , Pradhan Hema Kumari , Parajuli Rakshya
Published: September 2024

Persistent Müllerian duct syndrome is a rare autosomal recessive disorder of sex development characterized by the presence of Müllerian duct derived structures in a normally virilized, genotypical (46, XY) and phenotypical male. Here we describe a case of male partner of the couple who presented with primary subfertility and was diagnosed with persistent müllerian duct syndrome during investigations. Persistent Müllerian duct syndrome is a rare disease and in developing countries like Nepal, because of unaware of the disease condition and lack of proper health care facilities, such cases are diagnosed later in adult males. Therefore, this case highlights the importance of awareness and knowledge for early detection and treatment of such conditions to conserve fertility and prevent malignancy of testis and other remnant mullerian structures.

Authors: Pokharel Sangam , Silwal Shirish , Shrestha Prakash , Neupane Kabin
Published: September 2024

Carpal tunnel syndrome is an entrapment neuropathy of median nerve in wrist presenting with symptoms like pain, numbness, and paresthesia in hand and lateral three fingers. Conservative treatments are effective for mild to moderate cases, whereas severe or refractory carpal tunnel syndrome may require surgical intervention. Hydrodissection, a technique involving the separation of the nerve from surrounding tissues, has emerged as a minimally invasive and effective treatment option for carpal tunnel syndrome, leading to faster recovery and lower complication.In this case report, a 48 years female with two years history of severe pain and paresthesia in right hand, underwent ultrasound-guided hydrodissection of median nerve with 5% dextrose. Following intervention, the patient reported decreased symptoms and expressed satisfaction with the treatment during subsequent follow-up after 2 weeks. Ultrasound-guided hydrodissection of median nerve with 5% dextrose is effective treatment modality for patients with failed conservative management of carpal tunnel syndrome.

Residents of the Volga Region in the 35th Infantry Division of the Ruschuk Detachment in Bulgaria during the Russian-Turkish war of 1877–1878
Authors: Anshakov Yuriy P.
Published: September 2024

The article is devoted to the combat operations of the regiments formed in the Upper Volga region as part of the 35th Infantry Division of the Ruschuk (Eastern) Detachment in Bulgaria during the Russian-Turkish war of 1877–1878. In Soviet and contemporary Russian historiography, the actions of the Ruschuk Detachment and its military units, with rare exceptions, remained beyond the interest of researchers who focused their attention on the main events of the Russian-Turkish war. The author analyzes the mistakes and miscalculations of the leadership of the Rushchuk detachment, which led to defeats in the battles of Ayazlar and Kara-Khasan-Kioi, as well as the victories of the Russian troops at Chayir-Kioi and Mechka-Trastenik. Attention is drawn to the difficulties in the relationship between Grand Duke Alexander Alexandrovich, who led the Rushchuk detachment, and the leadership of the Danube Army in the person of Commander-in-Chief Nikolai Nikolaevich (senior) and the army headquarters.
Tectonic ledges at the Ladoga Lake bottom
Authors: Anokhin V. M. , Dudakova D. S.
Published: September 2024

For the past few years, the Institute of Limnology of the Russian Academy of Sciences has been conducting geological and geomorphological studies of the bottom of Lake Ladoga. Starting from 2018, underwater photo and video cameras developed at the Institute began to be used in these studies. The use of this new research tool led to the discovery of a number of new facts about the structure of the bottom of Lake Ladoga. In particular, at the bottom of the northern part of Lake Ladoga, three subvertical ledges were found, composed of bedrock, up to 70–100 meters high. According to a number of features, such as the bedrock composition of rocks, morphology and spatial correspondence to known fault zones, these ledges can be recognized as morphological expressions of tectonic objects – faults of presumably fault type. The absence of visible traces of glacial processing on the bedrock blocks suggests the Holocene age of the formation of these ledges and, accordingly, the existence of modern active tectonic movements in the area of Lake Ladoga.

Authors: Bilichenko I. N. , Rasputina E. A.
Published: September 2024

The northern regions of the Irkutsk oblast have been prone to fires in recent decades as a result of oil and gas and infrastructure development, as well as changing climatic conditions. Geoinformation mapping and analysis of the spatial structure of the vegetation cover of two key areas located in the area of the Vershina Khandy village and the village of Tokma for two time slices: 2013–2014 and 2018–2019 (before and after active forest fires, mainly in 2016 and 2017) was carried out. Mapping was done using the Random Rorest supervised classification method, Landsat 8 space images. As a result, 10 classes of vegetation cover were identified on the territory. It is shown that in the territories in 2013–2014 coniferous (light coniferous – pine-larch, larch-pine, less often dark coniferous – cedar and spruce) forests prevailed, as well as mixed coniferous-deciduous and deciduous forests and swamps. From 2013 to 2019, more than 20% of Tokma and more than 5% of Khanda key area was covered by fires. Mostly coniferous forests, as well as ernik bogs in the Tokma area were burning.

Authors: Manakov А. G. , Terenina N. K.
Published: September 2024

The purpose of the study is to identify the features of ethno-demographic processes in Crimea during the first two decades of the 21st century. The work is based on statistical and cartographic research methods. The nature of ethno-demographic processes in the territory of Crimea in the period between the population censuses of 2001 and 2021, which saw a change in the political subjectivity of the peninsula, was determined by the growth in the number and share of the Russian and Crimean Tatar population. At the same time, there was a significant reduction in the size and proportion of the Ukrainian population, caused by both migration outflow and a change in ethnic identity. In addition, the study was able to identify an important spatiotemporal component of ethnodemographic processes in Crimea during this period – the increasing concentration of the main ethnic communities (Russians, Ukrainians and Crimean Tatars) in the southern part of the peninsula.

The purpose of the research is to study, the effect of N deficiency in irrigation solutions on the structural and functional characteristics of spring barley (Hordeum vulgare L.), the Oplot variety under controlled environmental conditions, in comparison with the structural and functional characteristics of Takmak barley, which has been the standard in all variety testing sites of the Krasnoyarsk Territory since 2022. The plants were grown under light culture conditions using hydroponics on expanded clay with constant environmental conditions at a photoperiod day/night of 17h / 7h, respectively. The basis for the preparation of irrigation solutions was Knop solution (control) and a solution in which, in order to reduce the concentration of N-NO3, the salt content was changed 2 times so as not to change the concentration of other macronutrients. A comparison of the rate of absorption of macronutrients by barley plants of the Oplot and Takmak varieties, depending on the composition of the irrigation solution, shows a higher demand of the barley of the Oplot variety for the presence of mineral nutrition elements in the irrigation solution in comparison with the barley of the Takmak variety. The deficiency of N in the irrigation solution led to a decrease in total tillering by about 2.5 times, but productive tillering in the barley of the Oplot variety decreased to a greater extent than in the barley of the Takmak variety. When growing on Knop solution the barley of the Oplot variety showed higher productivity than the barley of the Takmak variety. When grown on solutions with a deficiency of N, the grain yield of the barley of the Oplot variety decreased by 2.8 times, and in the barley of the Takmak variety, the differences between the control and experimental variants were unreliable. The barley of the Takmak variety showed higher resistance to N deficiency in the irrigation solution, thereby showing higher plasticity compared to the barley of the Oplot variety.

Published: September 2024

To grow high and stable yields with good product quality, it is very important to receive timely, full-fledged and friendly shoots of optimal density. Therefore, the problem of stimulating, or inhibiting, seed germination and the processes occurring in them occupies an important place in modern crop production. The method of pre-sowing seed treatment with rhizobia is one of the promising technological measures that ensure an increase in yield and quality of crop production. The staff of the Laboratory of Biological Research of the Federal State Budgetary Budgetary Institution of the Federal Research Institute of Soy conducted a study of the possibility of stimulating germination and disinfection of soybean seeds, lupin, vigna, wheat, barley using pure Sinorhizobium fredii crops. The work used collectible strains of rhizobia, which showed an abundant growth of bacterial mass on the nutrient medium of the MRC. The standard strain was S. fredii 5851 from the collection of microorganisms and cell cultures of the Leibniz Institute (DSMZ), Germany. In variants with strains, stable stimulating and healing effects were observed. As a result of a scientific experiment, it was found that, on average, in variants with S. fredii strains, germination increased by 37%, the length of seedlings – by 224%, the raw weight of seedlings – by 23% compared with the control (without treatment with strains). S. fredii strains BB-49, SB-39, SB-43, TB-422, TB-488, TB-490, TB-496, 062 maximally stimulated the process of germination of agricultural seeds.

Published: September 2024

While discussing the establishment of scientific school of grapevine genetic resources, breeding and genetics in Russia, its formation is of undoubted scientific importance not by one individual only, but generally by studying and analyzing the contribution of generations of scientists in the country, focusing, as a baseline, on fundamental researches and stated theories of N.I. Vavilov. Analyzing the historical and modern stages of grape breeding methodology in conjunction with source material – genetic resources, and those determined by the specificity of pattern genome manifesting and inheriting genetically determined traits, it is necessary to highlight two aspects: the process of grape gene pool formation, the origin of individual varieties in the process of natural evolution, and task-oriented creation of new cultivars in the process of experimental evolution. Understanding of the methodology of grapevine natural morphogenesis in due course generated the methodology of targeted creation of new cultivars. Natural hybridization, natural mutagenesis and natural selection as initial methods of grapevine morphogenesis for generations of Russian scientists made it possible, using descriptive ampelography, to further move to directed hybridization, induced mutagenesis and induced polyploidization in combination with artificial selection. And only recently the transition from breeding at the organismal level to genome editing at the gene level became possible using modern bioengineering methods and various approaches to gene engineering.

Traditionally, forecasting apple tree yields was carried out on the basis of statistics of already obtained long-term yield dynamics or based on generative formations formed on the tree. The purpose of the work is to identify the most significant soil parameters for the formation of the apple tree varieties yield on the dwarf rootstock 62-396 and to build a mathematical model for predicting fruit yield in the conditions of the Central Chernozem region of the Russian Federation. Field research was carried out in 2004-2022 in industrial apple tree plantations at the age of full fruiting in the Lipetsk (two farms) and Tambov (eight farms) regions. Seven horticultural soil types have been studied. Based on statistical analysis, a mathematical model of apple tree productivity was obtained in the form of an analytical dependence on three factors. A geometric interpretation of the regression model is given using the Mathcad symbolic mathematics system in the form of response surfaces and the corresponding level lines. Practical recommendations are given for choosing rational parameters within selected intervals of factor variation.

The components of electricity consumption by iron ore enterprises are generalized and studied. On the basis of systematicity, a mathematical model has been built that allows developing a methodology for assessing the efficiency of electricity consumption under a three-zone tariff grid. The mathematical modeling of electricity consumption by iron ore enterprises as a complex object makes it possible to numerically determine the impact of the value of electricity consumption on the cost of electricity consumption by an iron ore enterprise. This approach made it possible to obtain quantitative indicators of the efficiency of electricity consumption at specific iron ore enterprises. The methodology for assessing the efficiency of electricity consumption at iron ore enterprises was further developed. For the first time, a model for assessing the efficiency of electricity consumption under a three-zone tariff grid was formulated and built. The proposed methodology can be used as a basis for unifying the quantitative assessment of electricity consumption efficiency. The analysis of the results makes it possible to conduct a quantitative and qualitative assessment of the efficiency of electricity consumption processes on the basis of system-parametric modeling for iron ore enterprises. The developed methodology can be unified for implementation at iron ore enterprises of the national economy. It is advisable to include the developed model in the practice of relevant calculations of the economic activity of iron ore enterprises.
It has been established that in the current conditions of functioning of iron ore enterprises it is advisable to study the consumption of electricity as a systemic complex object. The carried out analysis made it possible to build an objective function that takes into account the consumption of electricity by ore intake devices depending on the time of day

According to the analysis of the designs of technological machines that have several executive mechanisms that work sequentially according to the technological diagrams and receive movements from the electric drive through chains of mechanical transmission mechanisms consisting of a set of kinematically connected friction pairs and parts, complicated in the design and its production, have reduced reliability in operation.
The authors propose a developed hydraulic system for distributing motion to the working mechanisms of the technological machine, which consists of an original design of a multi-position, multi-line hydraulic apparatus, which can ensure the distribution of motion to several hydro motors of the working mechanisms of the technological machine in accordance with the cyclogram of its operation and replace the chains of mechanical transmission mechanisms and parts.
The originality of the design of the multi-position, multi-line, single-spool hydraulic device is that it combines the properties of a spool- and valve-type hydraulic distributor, and the spool itself has a complex sectional cylindrical shape with cut sectors and makes a rotary, not reverse translational movement. The developed hydraulic device can perform both distribution and control functions and can replace controlled automatic devices.
A math model for calculating the volume of the working cavities of the hydraulic device (hydraulic distributor) was developed.
In order to check the operability of the hydraulic apparatus of the new design, its parametric modeling in the SolidWorks system and a cycle of experimental studies using the FloWorks module were carried out.
The results of the distribution of liquid in the hydraulic apparatus for individual cavities connected to the hydraulic lines of the hydraulic motors of the working mechanisms of the technological machine were obtained.
The principle of designing a new hydraulic device can be used to distribute liquid in technological machines with different cycles of mechanism interaction.

If high-quality water treatment for boilers is not organized, the impurities present in untreated water lead to a number of problems: large colloidal and mechanical impurities in the form of scale, rust, clay or sand quickly clog the pipes, significantly reducing their internal diameter. This causes the failure of shut-off valves and pumping equipment: hardness salts and other poorly soluble salts (carbonates, magnesium and calcium sulfates, silicates, various compounds of copper and manganese) settle, creating a crust on the metal walls of the equipment, which reduces its heat output. This contributes to a reduction in boiler power, increases energy costs, and significantly shortens the life of the equipment. Based on the analysis of the latest research, it is proposed to improve the quality and composition of water that comes from municipal water supply, artesian wells and reservoirs, before filtering and deaerating water, it is proposed to pre-treat it with hydrocavitation and a magnetic field in order to soften and change its properties. The essence of the operation of the proposed equipment is that the effect of sound hydrocavitation and a variable magnetic field on water is reduced to a single process - the splitting of water molecules in the cavitation cavity into active radicals. The essence of various processes, namely hydrocavitation and magnetic influence on the passage of chemical reactions, breaking of hydrogen bonds in water molecules, is considered. The design of the equipment for the incoming magnetic cavitation preparation of water with an additional hydrocavitation effect on water during the reciprocating movement of the liquid through the nozzle is proposed, which combines the effects of breaking hydrogen bonds in water molecules, oxidation of iron and calcium ions, increasing the Рn indicator, and after its after settling, it is fed to the ion exchange and deaeration units, and later to the heating mains.
