Authors: Caballero Sharlie , Vera John De , Mangubat Randy , Calasang Veronica
Published: February 2025

This study determined the influence of teacher’s classroom strategy on learners’ mathematics performance in Zapatera Elementary School in the school year 2024-2025. The descriptive-correlational research methodology was utilized to examine the effectiveness of differentiated instruction, student engagement strategies, contextualized learning materials, and the integration of real-world scenarios, as well as their potential influence on students' academic performance The learners' profile revealed that most were 11 years old, with a nearly equal distribution of males and females. Families generally had moderate incomes, with parents predominantly holding at least a bachelor’s degree. Most learners came from small families with one or two siblings, though some were only children. Findings indicated that teachers effectively implemented a variety of strategies to enhance learning. Differentiated instruction and student engagement strategies fostered personalized and active learning experiences, while contextualized learning materials and real-world scenarios helped students connect mathematics to practical applications. Despite the positive perceptions of these strategies, the learners’ academic performance, rated as very satisfactory across all assessed topics, showed no statistically significant correlation with the classroom strategies employed. These results suggest that while the strategies create an inclusive and engaging learning environment, their direct impact on specific academic performance may be limited. Other factors, such as student motivation, prior knowledge, and assessment design, may influence academic performance. The study recommends a Teacher Support and Development Program to refine instructional practices and address these gaps.

O extrato de pólen é adquirido a partir do pólen granulado, resultando em uma substância sem constituintes alergênicos. Devido a essa característica, o pólen vem alcançando mercado como suplementação nutricional e também na área de cosmética. No entanto, a literatura quanto à atividade antimicrobiana do produto ainda é bastante escassa. Assim, o presente estudo objetivou avaliar a atividade antimicrobiana de extratos de pólen da Melipona fasciculata, retirados de meliponários nos municípios da Baixada maranhense, no Estado do Maranhão. Para constatar tal efeito, realizou-se as técnicas de microdiluição e perfuração em ágar frente às seguintes cepas: Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Klebsiella pneumoniae (ATCC 700603), Staphylococcus aureus (ATCC 29923), Enterococcus faecalis (ATCC 29121), Streptococcus pneumoniae (ATCC 49619). Dentre as duas técnicas realizadas, evidenciou-se que apenas na perfuração em ágar foi possível constatar efeito antibacteriano frente a duas cepas, Pseudomonas aeruginosa e Enterococcus faecalis. Na técnica de microdiluição o extrato de pólen não demostrou atividade contra nenhuma cepa utilizada. Com base nesses resultados, conclui-se que o extrato de pólen possui potencial antibacteriano, no entanto, estudos mais detalhados são recomendáveis.
How to Facilitate the Comprehension and Creative Interpretation of Literary Texts through Interactive Maps: Igiaba Scego's Prestami le ali and ArcGIS StoryMaps
Authors: D'Eugenio Daniela
Published: February 2025

A digital project that has been implemented in an advanced Italian grammar class during the 2023 Spring semester aimed to enhance the students’ comprehension of a literary text, provide them with an opportunity to creatively expand on it, and, simultaneously, offer a multimedia learning experience. Students applied ArcGIS StoryMaps to the content of Somali-Italian writer Igiaba Scego's Prestami le ali (2020). The software supported their understanding of the cultural, social, and historical components of the text by making its storyline and global geography easier to pinpoint and visualize. Moreover, it stimulated the students’ creativity by connecting the text to resources (textual, visual, digital) that made the story more accessible and in alignment with their own interests and/or areas of study. Students worked primarily in the target language (Italian) as they completed scaffolded and collaborative activities, both inside and outside of the classroom, and explored aspects of Italian history and culture.

Published: February 2025

Background: Pilonidal sinus disease is a common condition that requires surgical intervention, with primary closure and open techniques being the two main approaches. While both methods aim to manage the disease and promote healing, they differ regarding postoperative recovery, complication rates, and overall outcomes. In many cases, primary closure offers benefits in terms of reduced recovery time and fewer complications, but the comparison between these two techniques remains underexplored in specific settings. This study aims to compare the clinical outcomes of primary closure and open techniques in the surgical management of pilonidal sinus. Objective: To compare the clinical outcomes of primary closure and open techniques in the surgical management of pilonidal sinus, focusing on wound healing time, hospitalisation duration, return to work, and postoperative complications. Study Design: Randomized controlled trial. Settings: The study was conducted at a tertiary care hospital. Duration of Study: April 2024 to November 2024 Methods: A total of 60 patients with pilonidal sinus were randomly assigned into two equal groups. Group A underwent excision with primary closure, while Group B underwent excision with the wound left open to heal by secondary intention. Primary outcomes included hospitalization duration, wound healing time, and time to return to work. Secondary outcomes included complications such as wound infection and recurrence. Statistical analysis was performed using appropriate tests, including t-tests and chi-square tests, with p-values ≤ 0.05 considered significant. Results: Group A (primary closure) demonstrated significantly shorter hospitalization (4.37 ± 0.999 vs. 5.80 ± 1.27 days, p < 0.0001), faster wound healing (17.57 ± 1.72 vs. 44.73 ± 3.34 days, p < 0.0001), and earlier return to work (13.60 ± 2.47 vs. 30.43 ± 2.86 days, p < 0.0001) compared to Group B (open technique). Wound infection rates were lower in Group A (6.7%) compared to Group B (23.3%), with a statistically significant difference (p = 0.01). Recurrence rates were also lower in Group A (10.0%) compared to Group B (30.0%). Conclusion: Primary closure is more effective than the open technique in the surgical management of pilonidal sinus, offering faster recovery times, fewer complications, and better overall patient outcomes. When performed appropriately, this technique should be considered the preferred approach for pilonidal sinus surgery.

Authors: Caraçato Viviane de Oliveira Berloffa , Machado Maria Cristina Gomes , Huss Silvana Rodrigues Malheiro
Published: February 2025

Este texto tem por finalidade promover reflexões acerca do livro didático em uma perspectiva histórica e sua relação com a indústria cultural. Para fundamentar o estudo, recorremos aos trabalhos desenvolvidos por Adorno e Horkheimer (1985), Benjamin (1989), Bittencourt (2001, 2020), entre outros autores que discutem a temática proposta. Por entender que os livros didáticos são elementos da cultura escolar, e o meio educacional está entrelaçado a um contexto social mais amplo, logo, compreendemos que os livros didáticos possuem relação com tal estrutura. Nesse contexto, é possível enfatizar que o livro didático é uma mercadoria da indústria cultural, o qual reproduz as ideologias dominantes e gera lucros aos seus produtores. Assim sendo, é necessária uma avaliação rigorosa para a utilização deste material no processo de ensino e aprendizagem, tendo em vista a formação crítica e emancipatória dos sujeitos.
Atribuição docente e controle do ofício de professoras primárias rurais sob a ótica de Foucault (Londrina, PR, 1961-1969)
Authors: Faria Thais Bento , Mariano Jéssica Mayara Ariza
Published: February 2025

O estudo tem como objetivo conhecer as atribuições docentes e os mecanismos de controle do ofício de professoras primárias rurais de Londrina entre 1961 e 1969, sob a ótica de Michel Foucault (2014). Trata-se de uma pesquisa bibliográfica e documental, que articula as contribuições da produção historiográfica e toma como fonte documental as atas de reuniões pedagógicas e extraordinárias do Departamento de Educação do município de Londrina com o professorado da época. Conclui-se que as vocacionadas, missionárias e abnegadas professoras primárias leigas, palavras que as adjetivavam, era esperado que tivessem boa vontade, fossem conscientes de seus deveres e se sujeitassem às normas do departamento. Nos anos 1960, inúmeros trabalhos compunham o rol de atribuições docentes para além do estritamente pedagógico. À luz de Foucault, a pesquisa aponta a disciplina, o controle da atividade, a vigilância hierárquica e as sanções normalizadoras como mecanismos para forjar a professora desejada e controlar seu ofício. Todavia, o estudo considera que a insistência e a constância do controle indicam a correlação de forças, a contraconduta, a indisciplina e a resistência do professorado primário rural londrinense na década de 1960.

Current Concepts in the Surgical Management of Elbow Medial Ulnar Collateral Ligament Injuries
Authors: Spears Thomas M. , Luchinni Patrick , Camp Christopher L. , Bowman Eric N.
Published: February 2025

The elbow medial ulnar collateral ligament (UCL) serves as the primary soft tissue restraint to valgus stress and is therefore critical to the stabilization of the elbow in overhead-throwing athletes. Injuries to the UCL present with medial elbow pain and altered performance. Reconstruction of the UCL is the “gold standard” for surgical treatment; however, rehabilitation after reconstruction can take 12 to 18 months. Recent advances in technique have led to an increased interest in augmented UCL repair, which boasts a quicker return to sport at 6 months on average. Appropriate candidates for repair may include athletes with proximal or distal avulsions with otherwise adequate quality UCL tissue. Augmented repair is biomechanically equivalent to reconstruction and clinically demonstrates high rates of return to play (>90%). Recently, augmented reconstruction has emerged as a technique to merge the benefits of reconstruction with repair, although clinical outcomes have yet to be defined.

Published: February 2025

Evaluating large numbers of hackathon submissions quickly, fairly, and at scale is a persistent challenge. Existing automated grading systems often struggle with bias, limited scalability, and a lack of transparency. In this paper, we present a novel hybrid evaluation framework that leverages large language models (LLMs) and a weighted scoring mechanism to address these issues. Our approach classifies hackathon submissions using LLMs, converts Jupyter notebooks to markdown for consistent analysis, and integrates multiple evaluation factors—from technical quality to video presentations—into a single, balanced score. Through dynamic prompt engineering and iterative refinement against manually benchmarked evaluations, we mitigate prompt design biases and ensure stable, fair outcomes. We validate our method in a multi-campus GenAI and Cybersecurity hackathon, demonstrating improved scalability, reduced evaluator workload, and transparent feedback. Our results highlight the potential of hybrid AI-driven frameworks to enhance fairness, adaptability, and efficiency in large-scale educational and competitive environments.
Evaluation of Language Disorder in Children - A Case Study of Gboko Central Primary School Pupils, Benue State, Nigeria
Authors: Shar-Adura Oryina Bestman , Gbaa Emmanuella Nguevese , Asongo Linda Doom , Pilaku Kulenen , Anyam Serumun Solomon
Published: February 2025

Language disorders or language impairments are disorders that involve the processing of linguistic information. Problems that may be experienced can involve grammar (syntax and/or morphology), semantics (meaning), or other aspects of language. These problems may be receptive (involving impaired language comprehension), expressive (involving language production), or a combination of both. The fact that some children fail to acquire language abilities is the central concern of this research and is being identified as the major problem and subject of investigation in this study. The study adopts Chomsky’s theory of Universal Grammar. The interesting principle of this theory that makes it suitable for being a framework for this study is that it posits that children go through stages of language development, and the “mistakes” they make during this time only reveal their development stage, but during their maturation, they are resistant to correction. The evaluation was done in the semantic phonological and syntactic areas of language, including stuttering analysis. The information gathered shows that children are affected by various language disorders and degrees. The research suggests that parents should be sensitized to examine the language acquisition stages of their children so as to identify any disorder early as this is important for intervention and remedy. Although this school is not a special kind for this defect, the study is carried out to ascertain language disorder among these pupils.

Published: February 2025

The overall objective of this study is to analyze the most effective positioning strategies for the Tropicars lubricator in order to consolidate its presence in the market and improve the customer experience. Through exhaustive research on the positioning strategies of the competition and the current perception of Tropicars, key opportunities to add value were identified. A mixed methodology was applied, combining quantitative and qualitative approaches. Structured surveys were conducted with current and potential customers and complemented by observation and interviews to achieve a deep understanding complemented by observation and interviews to deeply understand consumer expectations and profiles. To ensure data reliability, SPSS version 25 software was used. The results highlight that Tropicars’ main differentiator is service quality, perceived as a key factor for customer satisfaction and loyalty. However, the research also revealed that there is an opportunity to modernise the brand’s visual identity, which would help consolidate its positioning in an increasingly competitive market. Furthermore, a stronger digital presence, especially on social media such as Facebook and WhatsApp, is considered essential to attract new customers and improve engagement with existing ones. The final findings suggest that Tropicars should reinforce its focus on service quality, adopt a modern visual image, and expand its digital presence to increase its visibility and market appeal
Bitumen Pollution and Heavy Metal Concentration in Surface Soil: Implication for Soil Conservation
Authors: Ogunsusi kayode
Published: February 2025

The purpose of this study is to determine the implications for soil conservation of heavy metal concentrations in bitumen-polluted soils. Bitumen-derived heavy metals pose a serious threat to the environment by contaminating soil and harming plants, animals, and ecosystems. The study was carried out at Ode-Irele in Ondo State of Nigeria where there were seepages of bitumen as well as exploratory activities. Composite samples of soils in bitumen seepages and exploratory sites were collected to a depth of 15cm and that of the control was obtained at Ebute-Irele. Heavy metals in soils – Mn, Fe, Cu, Zn, Pb, Cr, Cd, Ni, V, and As were determined using atomic absorption spectrometry. Data were analyzed using descriptive statistics and t-tests of unpaired samples. Results showed that Fe and V were more concentrated statistically in exploratory soil than in control, while only Fe was significantly concentrated in seepage soil than in control soil. Mn (805.00 ± 136.30 mg/kg), Cu (140.00 ± 73.50 mg/kg, 251.00 ± 21.21 mg/kg), and Zn (215.00 ± 105.48 mg/kg, 290 ± 56.57 mg/kg) respectively had statistically lower concentrations in both seepage and exploratory soils than control soil. Mn (805.00 ± 136.30 mg/kg, 870 ± 198.00 mg/kg), Fe (992.50 ± 115.30 mg/kg, 1110.00 ± 141.40 mg/kg), Pb (8.0 ± 3.00 mg/kg, 290 ± 56.60 mg/kg), and As (4.80 ± 1.30 mg/kg, 5.00 ± 0.00 mg/kg) are respectively common to soils where there were bitumen seepages and where exploratory activities have taken place with higher concentrations than corresponding values in bitumen. The values of Mn (805.00 ± 136.30 mg/kg), Cu (140.00 ± 73.50 mg/kg, 251.00 ± 21.21 mg/kg), Zn (215.00 ± 105.48 mg/kg, 290 ± 56.57 mg/kg), Pb (8.0 ± 3.00 mg/kg, 290 ± 56.60 mg/kg), Ni (13.00 ± 8.70mg/kg, 15.00 ± 7.10mg/kg), As (4.80 ± 1.30 mg/kg, 5.00 ± 0.00 mg/kg), Cr (9.75 ± 0.50 mg/kg, ± 10.00 ± 0.00 mg/kg) and Cd (2.50 ± 1.00 mg/kg, 3.50 ± 0.71 mg/kg) respectively in both seepage and exploratory soils exceed FEPA (1991) guidelines. Higher concentrations of heavy metals in bitumen-polluted soil should be continuously monitored during bitumen mining as they may represent significant environmental risks to soil conservation.

Authors: Jethro Michael , Shehu Shaib , Agbalajobi Sunday , Thomas Ayodele
Published: February 2025

It is vital to predict back breaks during blasting operations to avert the undesirable effect it might cause. For this reason, 40 blasting operations were witnessed in the Chinese Government Company (CGC) quarry to obtain the bench height, burden, hole diameter, and spacing. The pertinent equations were employed to compute the stiffness ratio and rock strength. Artificial Neural Network (ANN) methodology was adopted to analyze the impact of the different blasting parameters on the back break. The trained ANN is subsequently applied to predict back-break outcomes for new sets of blasting parameters. The results highlight a robust high correlation of (R2 = 0.9954) between the input blasting parameters and back break, underscoring their substantial influence on the phenomenon. Furthermore, the ANN model exhibits a high level of accuracy in predicting back breaks, suggesting its potential as a valuable tool for optimizing blasting parameters to mitigate back-break occurrences. It was observed that stiffness ratio has a higher effect on backbreak than rock strength. It was deduced that by using the predicted equation, there would be a reduction in back breaks as compared to the usual outcome after blasting.
ESG Perspectives to Investing: Translating ESG into Investment and Scores, and Challenges of Translations
Authors: Hong Dinh Minh Thi
Published: February 2025

p class="MsoNormal"Environmental, Social, and Governance (ESG) factors have
become integral in investment decision-making. Investors increasingly recognize
their potential impact on financial performance and long-term sustainability.
This article explores the various perspectives surrounding ESG investing,
focusing on the process of translating ESG information into investment
strategies and scores. However, the process of ESG translation is not without
challenges. The article thus addresses the complexities and obstacles inherent
in translating ESG factors into quantifiable scores and investment process. One
of the challenges in translating ESG into investment is the absence of
standardized metrics and inconsistency in reporting practices. Additionally,
the dynamic nature of ESG factors makes it challenging to effectively
incorporate future changes. Moreover, translation challenges arise due to
inadequate disclosure and transparency in ESG reporting. Addressing these
challenges requires collaborative efforts from stakeholders, regulators,
investors, and companies to establish guidelines and frameworks that encourage
consistent reporting and disclosure of ESG information.o:p/o:p
The Distorted View of Tax Neutrality as an Objective of the Robot Tax: A Misleading Desire to Treat Robots and Human Workers as Equals
Authors: Kerinc Narin
Published: February 2025

p class="MsoNormal"In recent years, the
debate surrounding the proposal of a robot tax as a response to the adverse
impacts of accelerated automation on human labour has gained significant
traction. Its increasingly skill-biased substitution with automation processes
is assumed to result in diminishing labour income tax revenues and
simultaneously increasing social transfer costs due to rising unemployment.
This assumption places the historically established role of labour income taxes
as a primary source of public funds under considerable scrutiny. The robot tax
is being discussed as a tool to safeguard the resilience of state transfer
systems and enable a smooth transition of the labour market by decelerating the
pace of automation in businesses that employ human workers. The current debate
is marked by an emphasis on the desire to create tax neutrality between robots
and humans. Further developing previous academic publications, this article
examines the concept of tax neutrality in the context of the robot tax.
Diverging from the focus on the tax neutrality of specified theoretical
frameworks for deploying a robot tax, however, it examines the neutrality
concept based on the nature of robots in comparison to labour. The article
concludes that the aim to equalize automated systems and human workers for tax
purposes is misguided and could ultimately distort tax neutrality.o:p/o:p

Study on the Effect of Biochar, Bentonite and Lignite on the Remediation of Heavy Metal Contaminated Soil
Authors: Shi Lei , Fan Hongjian
Published: February 2025

The in-situ repair of heavy metals in contaminated soil is to change the status of the presence of heavy metals in soil by applying some active passivation repair materials to the soil, and by dissolving precipitation, ion exchange adsorption, redox, organic convergence and other reactions, reducing the effective concentration, migration and biological effectiveness of heavy metals in the soil. This method is low-cost, simple to operate, fast-acting and suitable for large-scale promotion, and plays an irreplaceable role in the restoration of heavy metal contaminated soil. This paper summarizes the effect of passivation repair of biochar, bentonite and lignite on heavy metal contaminated soil. This paper analyzes the current situation of research in this field and the main problems in this field, and in the future, we should focus on the potential environmental risk of passivation repair agent to soil-crop system and the long-term stability evaluation of the field effect of passivation material repair.

High-Temperature Regulation of Manganese Oxide Hybrid for Efficient Alkaline Oxygen Evolution Reaction
Authors: Feng Tao , Lu Zonglong
Published: February 2025

Manganese-based oxides with diverse oxidation states, are promising electrochemical catalysts. In this work, we fabricated a novel hybrid electrocatalyst by integrating Mn2O3 and α-MnO2 on carbon paper (CP) using a two-step electrodeposition process, followed by annealing treatments at various temperatures. Notably, the hybrid electrocatalyst demonstrated significant performance enhancements compared to individual manganese oxides. In 1 M KOH electrolyte, the hybrid electrocatalyst displayed superior oxygen evolution reaction (OER) performance, requiring only a low overpotential of 290 mV to reach 10 mA cm-2. This electrocatalyst also exhibited excellent stability, maintaining performance over 12 hours. The results suggest that the synergistic combination of Mn2O3 and MnO2 plays a crucial role in enhancing OER performance.

Authors: Xi Baichuan , Zhang Taiyuan
Published: February 2025

With the growing global energy crisis and environmental pollution, developing sustainable energy technologies is urgent. Hydrogen, a clean energy source with high energy density and water as its only byproduct, is a promising alternative to fossil fuels. Electrolytic water splitting is a green hydrogen production method, but its efficiency is limited by the slow kinetics of the oxygen evolution reaction (OER). Developing efficient OER catalysts is crucial to improving this process. This article reviews the principles of electrolytic water splitting, in-cluding HER and OER mechanisms, and key evaluation parameters such as overpotential, Tafel slope, EIS, ECSA, and stability. It highlights transition met-al-based catalysts, particularly NiFe LDH, which enhances OER performance through the lattice oxygen mechanism (LOM). Future research should focus on optimizing catalyst design to advance electrolytic water splitting technology.

Collaborative writing represents as an integrated technique for tackling students' writing difficulties. Consequently, practising Collaborative Writing (CW) through online technologies, notably Google Docs (GD), can be an innovative model that assists student learning. However, in addition to its credits, this model is not without drawbacks. The current study attempts to demonstrate users' perspectives on the limits of collaborative writing via Google Docs and how they deal with them. The researcher employed a qualitative case-study approach and data collection via a questionnaire at Van Lang University in Ho Chi Minh City. The questionnaire consisted of 17 closed-ended questions to collect data from 9 student participants. The results revealed several advantages of Collaborative Writing as supported by Google Docs (henceforth CWGD), alongside some limitations and challenges to this approach/model.

The purpose of the research is the yield of lentils increase by stabilizing the phytosanitary of the seed material. A number of aspects (the consumer prefers other legumes, a small number of markets, low yield, high demands of the crop for agrotechnical terms, weather conditions and cultivation technologies) reduces the interest of farmers to the cultivation of lentils. Sergievsky area of the Samara region is referred to the risk farming territory, so the production of agricultural crops here is unstable from year to year. Crop losses reach up to 35% annually due to pests, diseases and weeds. The conditions for increasing the yield and improving its quality are the following: control of the phytosani-tary of crops, seed material, as well as the sowing of varieties resistant to diseases. In the last five years, the area of lentil cultivation by the farms of the Sergievsky district of the Samara region includes territory between 320...2109 hectares. The size of the planting acreage is unstable, since the main aspect in solving the need for cultivating a crop is dependence on the market for its sale. The seed material intended for sowing in 2020 was mainly attacked by fungal diseases and only minor part (4%) by bacterial ones, the damage of non-infectious diseases with an unknown etiology was noted amounting to (10%). The highest lentil yield was obtained in 2018 by the management of «KAPK – Invest» LLC – reaching 13.5 c/ha, which is 4.8 c/ha higher than the average yield figure obtained in the Samara region, and 2.2 c/ha higher than the average regional yield obtained in 2018. The use of this experience achievement in agricultural production, namely, the study of stabilizing variants for the phyto-sanitary level of the seed material, will increase gross lentil yield.

The purpose of the research is the morpho-chemistry blood value determination of high producing cows depending on the lactation period. The studies were carried out involving Holstein breed with a milk yield of 8500 kg or more. One group of cows-analogues was formed in regard to age, productivity and directional selection. Studies of blood chemical values were carried out during peak and end of lactation. Based on the conducted studies, it was found that milk productivity of cows, depending on the lactation period, affects blood values. During peak lactation of cows, the content of: erythrocytes by 1.061012/l, segmented neutrophils – by 3.80%, monocytes – by 1.06%, stab neutrophils – by 2.95%, hemoglobin – by 22.70 g/l, and in the blood serum: calcium by 0.16 mmol/l, glucose – by 0.48 mmol/l, total protein – by 18.23 g/l more than at the end of lactation. During the period of less intensive milk production and an increase of pregnancy period the content of platelets in blood is higher by 24.49109/l, basophils – by 1.04%, inor-ganic phosphorus – by 0.16% compared to the lactation peak period. The ratio of the albumin-globulin coefficient was higher than the threshold level during the period of peak lactation by 0.24, and at the end of lactation by 0.45. An in-crease of albumin-globulin coefficient confirms a decrease of calcium content in the blood serum. The morpho-chemical blood values of cows, taking into account the lactation period, can serve as base for developing of feeding technology, keeping high producing cows to prevent metabolic disorders by the end of lactation and correction during the dry period.

The aim of the research is to improve the nutritional value in the diet of dairy cows using complex mineral sup-plement – natural Volgograd bischofite. During the organization of scientific and economic experience, the selection of twenty dairy cows of the Red Steppe breed was carried out, of which two groups were formed including equal numbers of animals. Selection of cows into the groups put into comparison was carried out using a method that takes into account the principle of analogue pairs for experimental individuals. The experimental work was performed involving full-grown animals from the beginning of the lactation period. Cows of the 1st control group received feed and supplements of the main diet, and animals of the 2nd experimental group received Volgograd bischofite in addi-tion to the main diet. Blood parameters were studied from 10 individuals taken from each group of animal analogues in equal quantities. The results of the study revealed that the studied blood parameters of cows from both groups corresponded to their physiological norm. The introduction of a complex mineral supplement into the diets of animals of group 2 had a positive effect on the biochemical parameters of blood composition. According to the scientific and economic experiment completed, the blood serum of cows of the 2nd experimental group had more total protein by 1.87%, albumins – by 2.42%, globulins – by 1.46% than in the blood serum of animals from the 1st control group when fed a diet without bischofite. The individuals of group 2 had an advantage in the absolute content of globulin fractions in blood serum, namely alpha and gamma globulins, than of the animals of group 1, respectively, by 0.50 g/l (4.42%) and 0.80 g/l (3.51%). When using a mineral supplement of Volgograd bischofite as part of diets, its positive effect on milch cow productivity, milk quality and profitability of its manufacture was revealed.

The purpose of the research is to increase the yield of spring durum wheat grain depending on the method of tillage in the conditions of the Volga forest–steppe. The methods of tillage were studied – plowing, loosening and without autumn tillage, and quantitative indicators – the completeness of seedlings, field germination, the number of plants before harvesting, the safety and survival of plants, biological yield and grain yield of spring durum wheat, as well as the accumulation of straw mass left on the field in the conditions of the Volga forest-steppe. In the plowing variant, the highest values of germination completeness, field germination, survival and preservation of plants were obtained. In the variants with loosening and without autumn mechanical tillage, the studied indicators had lower values: field ger-mination – by 0.6 and 2.9%, germination completeness – by 0.6 and 3%, plant survival – by 2.35 and 2.21%, plant safety – by 0.7 and 1.1%, biological yield – by 2.6 and 3.9%, grain yield – by 5.2 and 10.9%, straw weight –
by 4.3 and 11.2%, respectively. The studied indicators of the production process, such as the fullness of seedlings, field germination, the number of plants before harvesting, the safety and survival of plants ensured the optimal, for the prevailing weather conditions, values of biological yield and grain yield of spring durum wheat, as well as the ac-cumulation of straw mass left on the field, depending on the tillage systems – plowing by 20-22 cm, loosening
by 10-12 cm and without mechanical processing in the conditions of the forest-steppe of the Volga region. The coeffi-cients of correlation of yield with quantitative indicators – field germination r = 0.63, germination completeness
r = 0.71, number of plants before harvesting r = 0.57, plant survival r = 0.75, safety from germination to harvesting
r = 0.58 showed a close direct relationship of signs.
