An Innovatively Woven Totemic Ewe Kete with Lace Effects for Unity and Identity in the Volta Region, Ghana
Authors: Dr. Abdul Fatahi Ibrahim  , George Akoto  , Issahaku Boyong Gbene
Published: December 2024

The purpose of this study was to identify and generate motifs from Ewe totems to be used in the design and construction of Ewe kete with "lace effect'' (or breathable) to symbolise the unity and identity of the Ewe people in Ghana. As an art studio-based practice, the study employs Adobe Photoshop, the computer graphics software that aids in easily manipulating images for textile designs, as a main design tool for generating the designs. Motifs were developed from various clan totems in the Anlo state and finally used to weave the Ewe kete with a Traditional loom. The research was based on a qualitative approach using studio-based practice and descriptive research methods. A purposive sampling technique was used to determine the sample population of chiefs, linguists, kete weavers and kete sellers. Observation and unstructured interview guides were the main instruments used for data collection. The study revealed that clan totems from Agbozume, Klikor, Anloga, Keta and Anlo-Afiadenyigba and the adjoined communities from Ketu South Municipality and Anlo-Keta Municipality could be fused or embedded into Ewe Kete. This study concluded that totems and other traditional symbols can be used for textile design (weaving) with relevant computer-aided software. It emerged from the study that the woven Kete fabric can educate the youth and identify and unite clans and the weaving industry in the region. The researchers, therefore, recommended that a chart of the traditional Ewe totems, as well as the abstracted ones made by the researchers, should be displayed in museums, libraries, and cultural and social centres for identification and education.

Authors: Osmunda Ndunguru  , Dr. Catherine Muteti  , Evans Ogoti Okendo
Published: December 2024

The study examined how school committees at Mbinga Town Council contributed to the enrolment of students with special needs in public primary schools by using a community awareness strategy. The study employed concurrent design under a mixed-methods research approach, and the Social Theory of Disability guided it. The study population comprised 42 public primary schools (PPSs), 42 head teachers (HTs), 1203 students, 546 school committee members (SCMs), 553 teachers (Ts), and 19 Ward Education Officers (WEOs). Probability and non-probability sampling techniques were deployed to sample 12 PPSs, 120 students, 64 Ts, 12 HTs, 55 SCMs, and 2 WEOs, making 253 respondents. Quantitative data were collected through questionnaires, while qualitative data were collected through interview guides and focus group discussion guides validated by education research experts. The reliability coefficients of 0.891 and 0.861 for Ts and SCMs questionnaires one at a time were attained following Likert-type items using Cronbach's Alpha. The trustworthiness of qualitative data was ensured through peer debriefing and triangulation methods. Quantitative data were analyzed descriptively and presented in tabular form, while qualitative data were thematically deduced. The study found that school committees highly engage the community awareness strategy in varying ways to boost pupils with special needs enrolment through positive initiatives and partnerships with support services. This approach includes addressing parents' concerns, fostering inclusivity, and collaborating with educators and government for better resources and support. The study concludes that initiatives like school activities and barazas help students' perceptions be positive and that a comprehensive approach to inclusivity is shown by collaborations with outside support agencies and efforts to make information available to all parents. The study recommends prioritizing communication with parents and increasing government funding to ensure accessibility and foster a genuinely inclusive educational environment.
Effect of NGO Activities on Living Conditions of Informal Settlements in Kisumu City: An Empirical Literature Review Approach
Authors: Wicklife Odhiambo Okinda  , Dr. Ondiwa Simon Oluoch
Published: December 2024

Living conditions refer to circumstances regarding how people live. How people live is quite broad; it implies the quality of food people eat, the type and quality of houses people live in, the clothes people put on, access to health care, and access to quality education and sanitation. Living conditions define the overall well-being of a human being and, at times, are related to self-esteem and dignity. Besides, quality of living may dictate life expectancy and affect the nation's overall productivity. Living conditions have been a worldwide concern to non-governmental organizations, various local governments, and stakeholders. The study, therefore, investigated the effect of NGO activities on living conditions in informal settlements in Kisumu City. The study used a literature review method; the inclusion criteria were that the study only reviewed literature done in Kisumu related to living conditions, NGOs, and informal settlements in Kisumu. The key search words were living conditions, NGO activities, and informal settlements in Kisumu County, and the study used Google Scholar as the database source of the articles reviewed. Results of the study revealed that despite NGO activities in informal settlements in Kisumu City, the effects of such activities on living conditions are dismal and not quantified. The study recommends a joint effort by stakeholders such as the County Government, the Central Government, the private sector, local development finance institutions, international development finance institutions, and individual philanthropists to help salvage the poor living conditions in informal settlements in Kisumu City. This study is essential to the citizens living in informal settlements, central and County Governments, NGOs, private sector firms, and all the stakeholders.
Internal Controls and Customer Satisfaction in the Telecommunications Industry in Uganda: A Case of MTN Uganda
Authors: James Kawuki Stephen  , Robert Mindila  , Rita Nakaferro
Published: December 2024

Every business organization's success depends on the satisfaction of the customers. Whenever a business is about to start, customers always come “first” and then the profit. Those companies that succeed in fully satisfying their customers will remain in the top position in the market. Today's business company has known that customer satisfaction is the key component for the success of the business, and at the same time, it plays a vital role in expanding the market value. In general, customers are those people who buy goods and services from the market or business that meet their needs and wants. Customers purchase products to meet their expectations in terms of money.
The study sought to explain the extent to which Customer Satisfaction in the telecommunications industry is driven by internal controls, using MTN Uganda as a case study. Many in Uganda recognize the importance of customer satisfaction and so have tried to streamline internal controls. However, customer complaints still persist despite efforts to address areas of dissatisfaction. This may be because the majority of them do not effectively operate their internal processes and are not using appropriate strategies to address the challenges. The study was guided by three objectives:

To examine the effect of administrative policies on customer satisfaction in the telecommunications industry,
To examine the effect of accounting procedures on customer satisfaction in the telecommunications industry and
To examine the effect of auditing procedures on customer satisfaction in the telecommunications industry.

The study was based on a cross-sectional research design. 230 staff of the company were selected as respondents using a simple random sampling approach, and data was collected using a questionnaire. Findings show that there is a strong, positive relationship between administrative policies and customer satisfaction, there is a strong and positive relationship between accounting procedures and customer satisfaction in the telecommunications industry, and there is a strong and positive relationship between audit procedures and customer satisfaction in the telecommunications industry. The variables entered in the regression model explain an overall 65 percent variance in customer satisfaction at the company.
It was recommended that MTN Uganda conduct regular surveys of customers (current and potential) to assess their standing in expectations and satisfaction and identify areas that need critical attention. MTN Uganda should adopt the international customer quality guidelines, and all staff should undergo regular (every three months) refresher training regarding how to handle internal operations in their areas of speciality.
Harnessing Data Analytics and Artificial Intelligence in Healthcare: A New Dawn in Patient Care
Authors: Jinesh Kumar Chinnathambi
Published: December 2024

Healthcare solutions driven by artificial intelligence (AI) can offer more personalized, precise treatment options and better health outcomes; however, implementing AI in clinical settings can be complex due to cultural, economic, and regulatory factors. Leaders must overcome challenges, including data quality and bias, algorithmic trust, and skills deficits, while focusing on patient-centricity and treatment options. [1] The fast-paced digital revolution in the healthcare sector has generated a wealth of data, leading to significant opportunities for healthcare advancements through the utilization of Data Analytics and Artificial Intelligence (AI). This article delves into the incorporation of these technologies in healthcare and their transformative influence on patient care. Advanced computational methods and data analytics can scrutinize and interpret intricate datasets, uncover patterns, and establish meaningful correlations. When combined with AI's adaptive and predictive capabilities, this has the potential to significantly revolutionize diagnoses, treatment plans, and healthcare operations. AI's proficiency in machine learning equips healthcare professionals with foresight, enabling the prediction of potential health risks and proactive interventions. AI and Data Analytics also lay the groundwork for personalized medicine, tailoring medical treatments to individual patient profiles. They enhance patient monitoring, pharmaceutical development, and risk management while improving the effectiveness of telemedicine and robotic surgery. Embracing these technologies can enhance patient outcomes, lower healthcare costs, and transform traditional healthcare paradigms into more patient-centered and data-driven approaches. Despite the associated regulatory, privacy, and implementation challenges, the intersection of Data Analytics and AI shows excellent promise in reshaping the future of healthcare.
Soledades marxistas. Teoría, Literatura e Historia en Juan Carlos Rodríguez
Authors: García Miguel Ángel
Published: December 2024

El precio por arriesgar a cada línea, a cada nuevo libro, a cada golpe de pensa- miento distinto, es sin embargo la soledad teórica. Hablo de soledad en el duro campo de la teoría, con independencia de la compañía más o menos numerosa que, con posterioridad, pueda arrastrar un pensamiento distinto como el del maestro. Pero esto ya serían los efectos de ese pensamiento, su continuación o su prolongación en quienes lo leen y no pueden sino quedarse pensativos, no el acto mismo en que el pensamiento es pensado y se arriesga al pensarlo y al escribirlo, y mucho más al publicarlo. Me refiero entonces a ese tipo de soledad advertida por Althusser en el Maquiavelo que teoriza las condiciones políticas de la constitución del Estado nacional, el Maquiavelo que defiende escandalo- samente, contra todas las verdades establecidas en su tiempo, que la lucha de clases es de todo punto indispensable para el reforzamiento y engrandecimiento de ese Estado. Naturalmente, Althusser glosa al Maquiavelo que habla de la soledad del Príncipe: hay que estar solo para fundar un Estado. Esta soledad es aislamiento, pero por ella pasa la libertad: hay que estar solo para ser libre a la hora de cumplir con la tarea histórica de la constitución del Estado. Es decir, y como sigue glosando Althusser (1977: 317), que había que encontrarse, por fortuna y virtud, arrancado radicalmente y sin retorno de las formas políticas de la Italia de entonces, porque todas eran viejas, marcadas por el feudalismo y nada se podía esperar de ellas. El Príncipe solo podía ser nuevo si estaba dotado de esta soledad, de esta libertad para fundar el Estado moderno.

Introduction. The processes of storing petroleum products in tanks are accompanied
by operational losses of the stored product. As a result, various emergency situations
may occur, which causes a high fire hazard of tank farms. One of the main parameters
determining the level of fire danger of "large" breaths during storage of
petroleum products in tanks of vertical steel tank type is the amount of pressure of
their saturated vapors, which has a decisive influence on the size of zones of explosive
concentrations formed in tank farms when the vapor-air mixture is displaced during
pumping tanks. This leads to explosions and fires at production facilities, which can
have catastrophic consequences. Currently, new brands of petroleum products with
insufficiently studied physico-chemical and fire-hazardous properties are emerging,
which makes it difficult to assess the fire and explosion hazard of the object of
protection. The values of saturated vapor pressure of petroleum products presented in
regulatory documents and reference literature differ significantly from each other and
do not allow an objective assessment of the fire hazard of the protected object. Goals
and objectives. Experimentally determine the saturated vapor pressure of modern diesel
fuel brands for further use of this indicator in assessing fire danger and determining
the magnitude of fire risk at industrial facilities. Methods. In the course of the
study, analytical and experimental methods for determining the pressure of saturated
diesel fuel vapors were used. Results and their discussion. The pressure of saturated
diesel fuel vapors was determined experimentally. It is established that the values of
the saturated vapor pressure of diesel fuel are different and vary in a wide range. The
analysis of the data on the pressure of saturated diesel fuel vapors obtained by
analytical and experimental methods was carried out, as a result of which it was found
that the calculated value of the investigated indicator of the fire and explosion hazard
of diesel fuel is approximately 9 times less than the value obtained experimentally.
Conclusion. The analytical method does not require large material costs. The
experimental method is more expensive and time-consuming, however, it allows us to
obtain more reliable values of the pressure of saturated vapors of petroleum products.
Therefore, the experimental method for determining this indicator of the fire and
explosion hazard of petroleum products is more preferable. Keywords: saturated vapor

Introduction. The problems of urbanization and growth in the number of chemically
hazardous facilities located in the residential area are urgent. This trend contributes
to the increase of risks of emergencies arising from fires accompanied by the release
(spillage) of various emergency chemically hazardous substances (hereinafter – ECHS). As
a result, a significant part of the population may end up in a zone of chemical
contamination. Such fires are complex, as in addition to extinguishing the fire itself,
it is necessary to organize measures to precipitate a cloud of ECHS by means of water
curtains. The situation may be further aggravated by insufficient water supply. In such
a situation, the senior official at the fire should know the methods and algorithms to
support management decision-making when extinguishing a fire accompanied by the release
(spillage) of ECHS, this will increase the effectiveness of combat operations by fire
and rescue units. Purpose of the study. Determination of new input data for modelling
the actions of fire and rescue units carrying out water curtain deployment during the
deposition of an ECHS cloud. Methods. Analysis, synthesis, modelling, experiment.
Results and discussion. On the basis of a series of experiments on water curtain
installation by hand fire barrels new data on the area, height, width and thickness of
the water curtain obtained from the PROTEK-366 fire barrel have been obtained and
compared with the parameters of the water curtain obtained from the RS-70 fire barrel
with the NRT-10 nozzle. New initial data and the algorithm of calculation justification
of the number and technical equipment of the units, carrying out the water curtain
setting during the deposition of the ECHS cloud expand the possibilities of the software
tools for support of the management decision making when planning the combat operations
at the chemically hazardous facilities. Conclusion. The results obtained are used in the
preliminary planning of combat operations by fire and rescue units of the local Donetsk
fire and rescue garrison, as well as the preparation of plans and conducting command and
staff exercises and training. Keywords: algorithm; emergency chemically hazardous
substance; modelling; support; fire; control; chemically hazardous facility; experiment.

Introduction: Empathy is an important concept in medical disciplines as part of emotional intelligence and effective communication skills. “Be a relative before becoming a doctor” project is intended to be applied to medical school students who do not have contact with the patient at the preclinical stage which will enable students to internalize empathy.
Materyal and method: Students were enabled to meet with the patient and their relatives within ethical rules and to see the diagnosis and treatment processes in the hospital. In the quantitative dimension of the research, a survey form containing the Jefferson Empathy Scale student version and the general empathy scale was applied before the practice, the Jefferson Empathy Scale student version and the general empathy scale were applied again after the practice. In the qualitative dimension of the research, students were asked to write reoprts based on their experiences, and the reports they wrote were treated as documents and analyzed.
Results: The mean age of the students was 20.31±0.85 and 55.7% (n=64) were female students. There was a significant increase in the Jefferson empathy scale score after the empathy practice activity compared to before the empathy practice activity (p=0.0001). Toronto Empathy Scale score increases after the empathy practice activity, although there is no statistically significant difference compared to before the empathy practice activity (p=0.097). When the qualitative reports of students were examined, a total of 354 codes containing the expression of empathy were found. It was observed that empathy was most frequently expressed with waiting time, personal satisfaction and sadness about the disease.
Discussion: As a result of this study, in which we evaluated empathy levels both qualitatively and quantitatively, we found that empathy levels increased and patient satisfaction. Fort his reason, we believe that our project is applicable in the educational curriculum of all medical faculties.

В статье анализируется процесс трансгрессии социальности под влиянием элект­ронных коммуникаций. Выявляются изменения как объективной, так и субъектив­ной сторон социальных явлений. Виртуализация социальных практик и отношений ведет к трансформации атрибутов социального бытия — пространства и време­ни. Происходит социальная рестратификация и маргинализация. Информационное пространство превращается в важную среду человеческого существования, где реа­лизуются различные социальные практики, отношения, возникают новые социальные институты и преобразуются традиционные.

The article analyzes the process of transgression of sociality under the influence of electronic communications. The changes of both objective and subjective sides of social processes are revealed. The virtualization of social practices and relations leads to the transformation of the attributes of social existence — space and time. Social re-stratification and marginalization are taking place. The information space is turning into a significant environment of human existence, where various social practices and relations are realized, new social institutions arise and traditional ones are transformed.

The aim of the study was to analyze the possible impact of iron deficiency (ID) without anemia on physical and sexual development of adolescent boys
Materials and methods. 46 adolescent boys with ID without anemia (serum ferritin (SF) level <15 µg/l in the absence of inflammation defined by normal level of C-reactive protein) and 99 healthy peers were recruited in the study. All the participants were without underlining chronic illness. Average age was 14.8±0.9 years.
Results. Physical development of adolescent boys with ID without anemia did not differ from that of their healthy peers. We found no correlation between anthropometric indicators and SF level. The SF level was significantly higher in overweight or obese children as determined by bioelectrical impedance then in normal weight children (35.15 (20.8; 48.6) vs. 18.8 (16,4; 20,0), p<0.001) and more so in obese children (40.8 (19.4; 56.3) vs. 18.8 (16.4; 20.0), p=0.012). Body fat (rs = 0.210 p = 0.013), visceral fat (rs = 0.208 p = 0.014) and body fat percentage (rs = 0.239 p = 0.005) correlated with SF level. Sexual development of boys with ID without anemia was within the age norm, but it was generally on the earlier stage then in the control group and correlated with the level of SF: for pubic hair rs = 0.186, p = 0.028 and for genitalia development rs = 0.224, p = 0.008.
Conclusion. ID without anemia did not altered physical development of adolescent boys. Obesity or excess weight is associated with a higher level of SF, which should be considered when diagnosing ID. ID is associated with sower sexual development in boys.
Keywords: bioelectrical impedance, iron deficiency, adolescents, sexual development, physical development.

The development of cardiovascular diseases inversely depends on the cholesterol level of high density lipoproteins (HDLs). On the other hand, it is known that pathogenesis of many cardiovascular diseases is based on endothelial dysfunction. Such facts indicate a special role of this class of lipoproteins in the functioning of endothelial cells. Upon binding to various receptors on endothelial cells, HDLs initiate the induction of endothelial nitric oxide synthase, enhance the production of NO, and stimulate the synthesis of prostacyclin, thus leading to vasorelaxation. By suppressing the synthesis of intercellular adhesion molecules, HDLs prevent the migration of leucocytes and monocytes/macrophages into the vascular wall, exerting anti-inflammatory action. HDLs inhibit the production of reactive oxygen species, prevent apoptosis, and stimulate the proliferation and migration of endothelial cells. Understanding the mechanisms of the protective action of HDLs on vascular endothelium is a necessary stage in the development of new therapeutic agents with the endothelial protective properties.
Keywords: endothelial cells, high density lipoproteins, apoptosis, angiogenesis, cardiovascular diseases.

Endometrial cancer ranks among the leading malignant diseases of the female reproduc-tive system and remains a pressing issue in oncogynecology. Although endometrial cancer is pre-dominantly a disease of the menopausal period, 10-14% of cases are diagnosed in patients of re-productive age. Most of these women do not yet have children, making fertility-preserving treatment a priority. As such, if a patient wishes to maintain her reproductive function, standalone hormone therapy may be conducted. Hormonal treatment induces atrophy of the tu-mor-altered endometrium, after which estrogen-progestin medications restore its function. The article presents a clinical case of successful realization of generative function following a favora-ble outcome of endometrial cancer treatment. A 41-year-old patient with low ovarian reserve and unrealized reproductive potential was offered fertility-preserving treatment, involving hyster-oscopic resection followed by hormone therapy. In deciding on fertility-preserving treatment, the presence of favorable prognostic factors was considered: positive receptor status of the tumor and tumor differentiation degree. After treatment, follow-up examinations revealed no recur-rence or disease progression, and the patient was advised to plan for pregnancy using assisted reproductive technologies. However, this was not carried out because of the patient’s spontane-ous pregnancy. During gestation, the patient underwent regular oncogynecological examinations according to the established schedule, and no recurrence or disease progression was detected. At 35 weeks of gestation, a surgical delivery was performed, resulting in the birth of a girl weighing 2820 g, with a height of 48 cm and an Apgar score of 8/8 points. This clinical case demonstrated that fertility-preserving treatment for early-stage endometrial cancer not only cured the malignant process but also subsequently fulfilled the generative function, without reducing the effective-ness of the treatment.

Целью проведенных исследований явилась оценка ущерба, нанесенного почвам и землям процессами деградации в Калачёвском муниципальном районе Волгоградской области, при помощи федерального нормативно-методического документа («Методика определения размеров ущерба от деградации почв и земель», 1994). В качестве показателей деградации почв и земель выступили - уменьшение содержания гумуса, подвижного фосфора и обменного калия, изменение значений рН по сравнению со значениями соответствующих свойств не деградированного аналога (эталона), а также осолонцевание (доля почв со щелочной реакцией среды в составе пахотных земель). Свойства эталонной каштановой почвы для муниципального района определялись с использованием монографий «Зонально-провинциальные нормативы изменений агрохимических, физико-химических и физических показателей основных пахотных почв европейской территории России при антропогенных воздействиях» (2010) и «Красная книга почв Волгоградской области» (2017). Наивысшая (4-я) степень деградации исследуемых почв и земель обнаружена для показателей уменьшения содержания гумуса и осолонцевания. Выделение доминирующих показателей деградации позволило определить основные направления и разновидности работ по улучшению состояния почв и земель в этом муниципальном районе - внесение необходимого количества минеральных и органических удобрений, гипсование солонцеватых и солонцовых почв. При этом стоимость указанных работ должна, в целом, соответствовать определенной величине ущерба (19 255 руб./га).

This study aims to assess soil and land degradation of agricultural farmlands of Kalachev district, Volgograd region using “Methodology for determining the extent of damage from soil and land degradation,” 1994. The humus content, mobile phosphorus, exchangeable potassium, and pH and alkalization level were chosen as degradation parameters compared to the non-degraded soil sample (standard soil). Standard soil properties of Kashtanozem in the studied district were taken from «Zonal-provincial standards of changes in agrochemical, psysico-chemical and physical parameters of the main arable soils of the European territory of Russia under anthropogenic influences» (2010) и «Red book of soils of the Volgograd region (2017). The conducted chemical and physical analysis of sampled soils demonstrated the highest level of land degradation (4th) for such parameters as humus content and alkalization level. The identification of dominant degradation parameters allowed to take actions aimed to recultivate soils in the studied area. These actions are mineral and organic fertilization and gypsuming of alkali soils. The cost of recultivation works should be proportional to the damage (19 255 rub/ha).

Применение минеральных удобрений привело к увеличению выноса элементов единицей урожая пшеницы - вынос азота по увеличился на 0,3, фосфора - 1,8, калия - 1,6 кг/т. Вынос азота урожаем ячменя увеличился на 3,0 кг, фосфора и калия - на 3,6 кг/т.

The results of research on the use of lime and fertilizers in grain-fallow crop rotation in 2014-2016 are presented. The assessment of the balance of nutrition elements on grain crops in the conditions of the Trans-Urals was carried out. sapropels from Kurgan and sverdlovsk regions deposits were used at the leached light loam chernozem. Without fertilizers application, the nitrogen balance was -138.1 kg/ha, phosphorus one -48.9 kg/ha. When N30 P30 was applied, the phosphorus balance became positive (+17.3 kg/ha). At the control variant the relative removal of macronutrients by the wheat main products, taking into account the by-products, averaged over two years: N - 29.0, PO - 9.9, KO - 21.0 kg/t, by barley, respectively, N - 22.4, PO - 8.4, KO - 19.1 kg/t. The use of mineral fertilizers led to the increase in the elements removal by the unit of wheat yield - nitrogen removal increased by 0.3, phosphorus by 1.8, potassium by 1.6 kg/t. The removal of nitrogen by the barley yield increased by 3.0 kg, phosphorus and potassium - by 3.6 kg/t.

Препарат «Гумистар универсальный» Грин-ПИКъ обладает антиоксидантной активностью, во много раз превосходящей природные аналоги. В разведенной, в соответствие с рекомендациями производителя, форме гуминовый препарат (ГП) обладал соизмеримым уровнем антиоксидантной активности по сравнению с гуминовыми веществами почвы. Увеличение количества вносимого калийного удобрения (дополнительный К52 на фоне N64P64К64) обеспечило повышение урожайности на 70% (в расчёте на товарную часть) и более более высокое содержание в клубнях картофеля витамина С, калия и фосфора по сравнению с контрольным вариантом. Использование препарата Гумистар при выращивании картофеля на фоне минеральных удобрений в дозе (N32P32K32) способствовало прибавке урожайности картофеля на 16% (с учетом потерь), а также повышению содержания фосфора, общего азота, калия, незначительному повышению витамина С и существенному увеличению содержания крахмала в клубнях картофеля. Двукратное повышение дозы вносимых минеральных удобрений (N64P64K64) увеличивало прибавку урожайности до 20% относительно контроля, способствовало сохранению высокого содержания крахмала и значимому увеличению белкового азота. При этом фактическая окупаемость минеральных удобрений была в 2-3 раза выше при использовании Гумистара.

Fertilizer Gumistar universal "Green-PIK" has an antioxidant activity that is many times superior to natural analogues. In the diluted form, this humic preparation (GP), on the recommendation of the manufacturer, possessed a commensurate amount of this property of humic substances in the soil. An increase for fertilizer (additional K52 against the background of N64P64K64) provided a higher content of vitamin C, potassium and phosphorus in potato tubers compared to the control option, however, the return on mineral fertilizers was about 70% only in terms of marketable yieldThe use of Gumistar when growing potatoes with mineral fertilizers in a low dose (N32P32K32) contributed to an increase in potato yield by 16% (taking into account losses), as well as an increase in the content of phosphorus, total nitrogen, potassium, a slight increase in vitamin C and a significant increase in starch content in potato tubers. A twofold increase in the dose of applied mineral fertilizers (N64P64K64) increased the yield increase up to 20% relative to the control, contributed to the preservation of a high starch content and a significant increase in protein nitrogen. At the same time, the actual payback of mineral fertilizers was 2-3 times higher when using Gumistar.

Рассмотрены особенности действия азотных, фосфорных и азотно-фосфорных минеральных удобрений в восьмой ротации шестипольного зернопарового севооборота. Длительный стационарный опыт расположен на черноземе южном Правобережья Саратовской области. Установлено, что в восьмой ротации севооборота баланс фосфора и калия на всех вариантах опыта сложился остродефицитный. Баланс азота с допустимым уровнем возврата получен при внесении N33,3-46,6 на 1 га севооборотной площади. Одновременно в почве наблюдалось снижение содержания гумуса и валового азота. Минеральные удобрения оказали заметное влияние на подвижность гумуса, фракционный состав азота и минеральных фосфатов чернозема южного. Максимальную среднегодовую продуктивность шестипольного зернопарового севооборота (2,43 т з. е. на 1 га севооборотной площади) получили при внесении N46,6 P31,2.

The features of the action of nitrogen, phosphorus and nitrogen-phosphorus mineral fertilizers in the eighth rotation of a six-field grain-fallow crop rotation are considered. Long-term stationary experience is located on the Southern Chernozem of the Right Bank of the Saratov region. It was found that in the eighth rotation of the crop rotation, the balance of phosphorus and potassium in all variants of the experiment was acutely deficient. The nitrogen balance with an acceptable level of return was obtained when applying N33,3-46,6 per hectare of the crop rotation area. At the same time, a decrease in the content of humus and total nitrogen was observed in the soil. Mineral fertilizers had a noticeable effect on the mobility of humus, the fractional composition of nitrogen and mineral phosphates of the Southern Chernozem. The maximum average annual productivity of a six-field grain-fallow crop rotation (2,43 tons of grain units per hectare of crop rotation area) was obtained with the introduction of N46,6P31,2.

В последние годы использование препаратов с физиологически активными свойствами (биостимуляторов) в устойчивом сельском хозяйстве увеличивается. Биостимуляторы могут быть получены из различных органических материалов и включают, прежде всего, гуминовые вещества (ГВ), а также сложные органические соединения природного происхождения. Применение биостимуляторов приводит к повышению содержания питательных веществ в тканях растений и положительным изменениям обмена веществ. Поэтому разработка новых биостимуляторов стала предметом научного интереса. У растений, обработанных биостимуляторами, часто наблюдается значительное увеличение длины и густоты корневых волосков, и за счет увеличения площади впитывающей поверхности корневой системы эти вещества способствует усвоению питательных веществ растениями. В этой статье представлен обзор современной литературы по двум основным классам биостимуляторов: гуминовые вещества и природные биостимуляторы с антиоксидантными и антистрессовыми свойствами. Подробно описаны характеристики этих биостимуляторов и их действие на растения, обсуждаются особенности химического строения отдельных групп таких соединений, которые определяют их общее влияние на развитие растений

In recent years the use of preparations with physiologically active properties (biostimulants) in sustainable agriculture has been increasing. Biostimulants can be obtained from various organic materials and include, first of all, humic substances (HS), as well as complex organic compounds of natural origin. The application of biostimulants to plants leads to an increase in the content of nutrients in plants’ tissues and positive changes in metabolism. Therefore, the development of new biostimulants has become a subject of scientific interest. A significant increase in the length and density of root hairs is often observed in plants treated with biostimulants, and these substances contribute to the absorption of nutrients by plants due to an increase in the absorbent surface of the root system. In this article, a review of modern literature is presented on two main classes of biostimulants: humic substances and natural biostimulants with antioxidant and anti-stress properties. The characteristics of these biostimulants and their effect on plants are described in detail; the features of the chemical structure of individual groups of such compounds are discussed, which determine their overall effect on plant development.
