Installation of percutaneous endoscopic gastrostomy for children. The tactics of a nurse
Authors: Ivashchenko N. M.
Published: October 2024

The article is based on the data and experience of the Blokhin National Medical Research Center of Oncology of the Ministry of Health of the Russian Federation, obtained during endoscopic practice. Currently, the number of pediatric patients requiring installation of a percutaneous endoscopic gastrostomy is significantly increasing, due to the increase in treatment regimens and the expansion of the range of indications for its installation. PEG combines endoscopic and surgical stages. The nurse must know the difference and differences of each stage, as well as have all the basic and advanced knowledge about all indications, contraindications and any complications during and after surgery. Compliance by the nurse with all the rules of asepsis and antisepsis, knowledge of SANPIN, is the foundation of her professionalism. Interest in the process will undoubtedly influence the quality of medical care provided. The nurse must study and know all the instruments, consumables and additional materials for performing endoscopic surgery. Her clear actions and orientation in what is happening guarantees the speed and success of the manipulation. The purpose of this work will be to emphasize the importance of professional development for nurses. To achieve the goal, we use all facets of a nurse’s work: knowledge of the concept of «sterility», orientation in all stages of manipulation from preparing the room to its complete routine cleaning after the intervention, all theoretical knowledge about the reasons for installing a gastrostomy tube and free orientation in any types of complications, etc. All of the above guarantees that the operating room endoscopic nurse is interested in the process, which will undoubtedly affect the quality and convenience of the doctor’s work, and subsequently the patient’s quality of life. The main goal of the entire operating team is to improve the patient’s quality of life. Understanding the meaning of all surgical endoscopic interventions obliges the nurse to constantly improve their skills and engage in self-education.
Political Efficacy
Authors: Oser Jennifer
Published: October 2024

A fundamental question asked in early survey-based political communication research is whether people feel that their political actions can affect political processes. Research has consistently shown the centrality of this political attitude, known as “political efficacy,” for democratic functioning. In recent research, political communication scholars have asked whether the rise of digital media may transform the public’s sense of political efficacy for good (due to improved information access and interactive possibilities with decision-makers) or for ill (due to information overload and a globalized sense of powerlessness). The best available cross-national evidence to date indicates, however, that digital media use and political efficacy are positively associated, and that political efficacy has a similar positive relationship with online and offline political participation. Next-step research is needed to clarify more nuanced contextual effects, particularly for lower-status individuals who tend to have lower levels of political efficacy.
Relations among the Trifurcated Narcissistic Domains at Trait and State Level: Two of a Kind?
Authors: Bauditz Sophie Charlotte , Wright Aidan G.C. , Hess Ursula , Ziegler Matthias
Published: October 2024

This study explored narcissistic states using a hierarchical, trifurcated structure, examining state variability and trait-state associations of agentic extraversion, self-centered antagonism, and narcissistic neuroticism. The primary objective was to investigate whether the structural composition of narcissism, well-established in trait data, could be replicated in state data. We examined this structure at both between- and within-person levels in state data, including situation-specific compositions of narcissism. The study used data from an experimental study where participants (N = 189) met in groups of up to four people weekly over six weeks. Multilevel confirmatory factor analyses revealed that the narcissism structure was largely the same at both levels. However, within-person compositions of narcissism differed across affiliative versus controversial situations. In affiliative contexts, grandiosity manifested exclusively through agentic extraversion, with no expression through self-centered antagonism. In controversial settings, agentic extraversion and narcissistic neuroticism exhibited a slight negative association, contrasting the positive association observed across all group meetings. Our results show that narcissistic states exhibited less variability compared to the Big Five and rarely varied above their corresponding trait levels. This research contributes to a refined understanding of narcissism, highlighting the interplay between trait tendencies and situational factors in shaping narcissistic state expressions.

Published: October 2024

The Association of Public and Land-grant Universities (APLU) and The Pew Charitable Trusts (Pew) convened a cross-sector workshop to explore how to collectively foster the Public Impact Research (PIR) ecosystem. The workshop was supported by the National Science Foundation and the Burroughs Wellcome Fund. The workshop aimed to develop shared understanding and language, identify opportunities to partner productively, and co-create strategic approaches that span sectors to help faculty's public impact research (PIR) flourish.From the workshop discussions, a central theme emerged: the responsibility for facilitating a more robust PIR ecosystem must be shared equitably among all actors in the research enterprise. It is incumbent upon the entire ecosystem to align efforts, supports, and incentives to empower researchers in this crucial work.Workshop participants identified priorities for action across the PIR ecosystem. We identify the top five areas here:•Prioritize PIR: Advocate for national and international policies that recognize and incentivize Public Impact Research as a critical component of the research enterprise.•Develop Shared Understanding: Co-develop a core set of PIR values that can be interpreted and applied by disciplinary societies, institutions of higher education, college and university departments, publishers, funders, and policymakers.•Envision New Funding Practices: Strengthen innovative funding models to support PIR sustainably across the entire research cycle, including longer grant periods, targeted programs, and resources for both researchers and community partners.•Create Quality Standards: Develop rubrics, definitions, and ethical standards for quality PIR that are adaptable across sectors and disciplines, broadening the definition of research excellence to include public use and community engagement.•Align Research Incentives: Develop a shared vision for aligning research incentives across sectors and institutions, including recognizing PIR projects and scholars. Establish systems to track and evaluate PIR impact over time using quantitative and qualitative metrics.

Sanitary housing is one of the basic requirements for healthy living, for safety also included as fundamental right. Housing situation of households and structure reflects the socio economic and cultural identity of people. It is also determined by environmental condition. Athpahariya Rai community is a rare community found especially at Dhankuta. A self-administered structured and unstructured questionnaire in Nepali language was used to obtain information from household head, observation, discussion with key informant are used in this study. Most of the traditional households are in insanitary condition with cattle shed. The structure of household has been slightly changed with improving socio economic status and support of Dhankuta municipality but there is not any significant change in living standard of people with low productivity of land, lack of safe drinking water, low level of literacy etc. Roof is changed from straw to zinc sheet and bamboo wall has been changed into stone and mud wall, there are very few household with concrete structure. Modernity towards shelter is just started in terms of shelter in the study area.
Trend and Determinants of Early Postnatal Care in Nepal with a Focus on Women’s Autonomy
Authors: Aryal Yeshoda
Published: October 2024

Nepal has made significant strides in improving maternal and child health, notably reducing mortality rates over recent decades. However, challenges persist in meeting the maternal and newborn health targets outlined in the Sustainable Development Goals. Postnatal care is essential for the survival and well-being of both mothers and newborns, yet there is limited research on this topic in Nepal. This study aims to assess trends in early postnatal care coverage and analyze the factors influencing service uptake focusing on women’s autonomy. Using data from the Nepal Demographic and Health Surveys for 2011, 2016, and 2022, which included 10,991 mothers aged 15-49 with at least one live birth, the study revealed significant improvements in postnatal care coverage. The percentage of mothers receiving care within 48 hours increased from 43% in 2011 to 56% in 2016, reaching 72% in 2022. Despite this progress, 28% of mothers and newborns still lack timely postnatal care, which is crucial for their survival and well-being. Regression analysis indicated that women with greater decision-making autonomy are significantly more likely to receive postnatal care (adjusted OR 1.216, P < 0.01), even when accounting for socio-demographic factors. The study highlighted disparities in postnatal care coverage based on age, caste/ethnicity, education, occupation, province, urbanrural residence, wealth, and family size. These findings emphasize the need for targeted interventions to empower women and tailor maternal health programs to address the specific needs. Future research should focus on evaluating complete postnatal care coverage, assessing care quality, and exploring interventions to strengthen maternal health care.

Introduction: Adolescence is the period of transition and opportunity in which physical, psychological, and social changes occur. Adolescents have various sexual and reproductive health problems like teenage pregnancy, abortions, sexually transmitted infections, etc. This study was designed to investigate the adolescence’s knowledge and perspective towards sexual and reproductive health in Birendranagar Municipality of Surkhet, Nepal.   
Methods: A descriptive cross-sectional study was designed to investigate the adolescence’s knowledge and perspective towards sexual and reproductive health in Birendranagar Municipality of Surkhet, Nepal. Structured questionnaires were developed in close-ended form and administered to a selected sample population. The questionnaire contained questions in five domains: social-demographic data, knowledge regarding adolescents’ sexual life, knowledge on reproductive health and safe sexual behavior, practices of sexual behaviors, and other contextual factors. In this study, a total of 328 respondent’s questionnaires were issued, and 312 were valid. The response rate was 95%. 
Results: There were a total of 312 participants, 174 boys, 137 girls, and 1 third gender involved in the study. Around 80% of adolescents were from secondary level education, and only 20% were from basic level education. Nearly half of the adolescents had inadequate knowledge of adolescents’s sexual and reproductive health. Sexual abuse, unwanted pregnancy, early marriage, and STIs were the common reproductive health problems faced by adolescents.
Conclusion: So, based on the above findings, government of Nepal should make different plans and policies to solve the adolescent’s sexual and reproductive health problems.

Published: October 2024

This study analyses the global experience of introducing innovations in the energy sector to identify effective solutions that can be applied to improve the energy system of Ukraine. The research methods included a comparative analysis of international experience in the energy sector, an assessment of the possibilities of adapting innovative technologies to Ukrainian conditions, and an examination of technical and economic aspects of integrating new solutions. The study analysed the experience of countries such as Germany, Denmark, the United States, Finland, the Netherlands, Sweden, Japan, China, France, and South Korea, which have succeeded in implementing innovative solutions in the energy sector, in particular, in the integration of renewable energy sources (RES), the development of smart networks, energy decentralisation, energy storage technologies, and energy efficiency improvement. It is identified that the most efficient approaches include the integrated use of renewable energy sources in combination with energy storage, which ensures the stability of energy supply even in conditions of uneven electricity production. The importance of smart networks for optimising energy distribution and reducing losses is also emphasised. The decentralisation of energy and the development of energy cooperatives contribute to improving energy security and community engagement. The study also showed that the introduction of smart energy management systems at the consumer level helps to increase the flexibility of the energy system and effectively respond to fluctuations in demand. In addition, it is determined that the successful implementation of innovative projects in the energy sector requires state support through subsidies and regulatory incentives. Based on international experience, it is concluded that combining technical solutions with effective management and political initiatives is key to ensuring the sustainable development of the Ukrainian energy system
Research and improvement of the design of a sedimentation tank for hydropower and irrigation
Authors: Abilov Rashad Saffan
Published: October 2024

The study is devoted to the analysis and optimisation of the design of the sedimentation tank to increase the efficiency of settling solid particles in hydropower and irrigation systems. Both experimental and numerical methods were used to analyse and optimise the design of sedimentation tanks to increase their efficiency in hydropower and irrigation systems. The study examined and analysed various types of sedimentation tanks according to design schemes, flow regime, deposition dynamics and sediment flushing methods, and also considered recommended improvements for hydropower and irrigation of various types of sedimentation tanks. During the study, it was revealed that optimising the geometry of the sedimentation tank significantly increases the efficiency of solid particle deposition. Experimental data have shown that changing the angle of inclination of the walls and increasing the area of the bottom of the sedimentation tank contribute to improving the deposition of silt and sand. It has also been found that the use of special turbulent inserts reduces the particle deposition time and improves the quality of treated water. Hydraulic flow modelling has confirmed that a more uniform velocity distribution in the sedimentation tank reduces turbulence and promotes more efficient particle deposition. The introduction of automated systems for monitoring and controlling the cleaning process has made it possible to increase the reliability and stability of the sedimentation tank. As a result, it was proved that the proposed design and technological changes can significantly increase the efficiency and durability of sedimentation tanks in hydropower and irrigation. The study provides practical recommendations for improving the design of sedimentation tanks, which helps to increase their efficiency and reliability in hydropower and irrigation, thereby improving water management

Objectives: The study aims to investigate the relationship between external audit quality and its factors (i.e., auditor characteristics, audit firm attributes, and effectiveness of municipal internal control), as well as the moderation effect of supreme audit institutions between external audit quality and its selected factors, as perceived by accountants and internal auditors in Palestinian municipalities. Methods: To achieve the objectives, questionnaires were distributed to 309 accountants and internal auditors in 155 Palestinian municipalities. They have firsthand knowledge of the financial statements under audit and are in constant communication with external auditors. Smart PLS 3 was used for statistical analysis. Results: The results revealed that the direct relationships between audit quality, auditor characteristics, and effectiveness of municipal internal control were positive. These relationships were also positively moderated by supreme audit institutions. The relationship between audit quality and audit firm attributes was also positive, but it was negatively moderated by supreme audit institutions. Conclusion: Audit firms, audit profession regulators, and municipality administrators can use these findings as useful guidelines in determining the factors of audit quality required in municipal audit engagements. This study encourages future research to examine other moderators, such as politics and public elections.

The genetic features of the variety are manifested in the responsiveness of plants to environmental conditions. This reaction is expressed in the change in yield and the level of adaptability to growing conditions, therefore, the selection of high-yielding, stress-resistant and plastic varieties well adapted to the soil and hydrothermal conditions of the growing zone is a promising direction for stabilizing and increasing productivity without large economic costs. The objects of the study were statistical data on the yield of spring oats in the production of the Yashkinsky district (forest-steppe), as well as data on the yield of six filmy varieties: Creole, Mustang, Orion, Sig, Coeval, Poseidon and four naked ones: Taydon, Pomor, Progress and Gavrosh. Agrotechnics is generally accepted for the south-east of Western Siberia. Observations and counts were carried out according to the VIR methodology for studying the collection of barley and oats. The area of the plot is 25 m 2 , the repetition is four times. The sowing rate of oat seeds is 4 million viable seeds per 1 ha. Sowing in the second and third decade of May. Cleaning – the first decade of August. All varieties of oats turned out to be resistant to lodging: filmy forms – Sig, Creole, Mustang, Orion, Coeval, Poseidon, naked forms – Pomor, Taydon, Progress and Levsha (5 points). A high degree of yield stability was characterized by the filmy variety Kreol S1 2 = –0.83 (S1 2 < 1). The variety was distinguished by high stability and responsiveness to the improvement of environmental conditions bi = 1.38 (bi > 1, S1 2 < 1). In terms of responsiveness to growing conditions, the filmy varieties Mustang and Poseidon were the best (bi = 3.2÷4.8). Filmy varieties Rovesnik and Poseidon (Ymin – Ymax = (–12.4)÷(–13.2)), naked Pomor, Gavrosh and Taydon (Ymin – Ymax = (–5.8)÷(–6.4)) were distinguished by high stress tolerance. The high compensatory ability is characterized by filmy varieties of spring oats Sig, Poseidon (Ymin + Ymax)/2 =39.0÷39.5). Filmy varieties Kreol (100 %) and Sig (113.4 %), naked Pomor (100 %), Taydon (102.5 %) and Progress (158 %) in terms of the level of plasticity (Puss) are plastic. According to the sum of ranks, the filmy varieties of oats Sig, Poseidon (∑ranks = 251÷286), as well as the naked cultivar Progress (∑ranks = 253) showed themselves.

Published: October 2024

Most often, for electrocontact welding when restoring worn parts of machines, a steel tape with a thickness of 0.5...1.0 mm is used as a filler material. Powder filler materials for electric welding are rarely used due to the loss of expensive powder during welding and the difficulty in cooling the welding zone. However, the use of powder materials makes it possible to obtain a variety of coating properties and increase the adhesion strength of the powder coating to the base metal of the part. The paper presents the properties of coatings obtained by electrocontact welding of metal powders, namely, the adhesion strength of the powder coating to the base metal of the part, the surface hardness of the powder coatings and wear resistance. The purpose of the research: to evaluate the effect of the composition of the powder and powder compositions on the hardness, adhesion strength and wear resistance of coatings obtained by electrocontact welding. For electrocontact welding, metal powders of grades FBH-6-2, PG-С1, PG-С27М, "Sormite", PGR3.200.28, PRNH17СR4, PG1С were used. The adhesion strength was determined by the shear method on a P-125 press. The hardness was determined by the standard Rockwell method on a TK-2 hardness tester. Wear resistance was determined using an SMC-2 friction machine. It was found that the highest adhesion strength with the base metal of the part (steel 45) is observed in the powder coating of powder grade PG-С27М during electric contact welding in "hard" modes. The highest hardness was recorded for the powder coating from the Sormite powder. The least wear was observed for coatings obtained by electrocontact welding of powder compositions: PGR3.200.28+Sormite and PGR3.200.28+ВК8, however, wear of the counterbody (pads made of gray cast iron) when working with a coating of PGR3.200.28+VK8 had catastrophic wear after 3 hours wear tests. The use of powder filler materials for obtaining coatings on machine parts by electrocontact welding makes it possible to obtain coatings that are superior to coatings obtained by electrocontact welding of steel tapes. Thus, the adhesion strength of steel strips welded by electrocontact welding in "soft modes" is about 100...200 MPa, which is 1.2...1.4 times less than the adhesion strength of powder coatings. The hardness of steel tape and wire coatings reaches HRC60, and powder coatings up to HRC65.

The article discusses the effectiveness of the use of potassium sorbate and a mixture of formic and propionic acids as preservatives for liquid vitamin and mineral feed additives. Preservatives must meet the following requirements: 1) do not cause the formation of insoluble products when interacting with other components of feed additives; 2) be soluble at the pH values that the feed additive has; 3) effectively suppress the growth of microorganisms and ensure long-term storage of the feed additive. Liquid feed additives Active Mix VMG-500, Active Mix VMG-600, Active Mix VM 10 and Active Mix VM 20 were used, to which these preservatives were added in concentrations from 0.05 % to 0.8 %. When adding a mixture of formic and propionic acids, the pH was adjusted (by adding NaOH) to the desired values (for Active Mix VMG-500 and VM 10, pH = 6.2, and for Active Mix VMG-600 and VM 20, pH = 3.2). At the same time, their salts were formed. It was found that potassium sorbate is incompatible with Active Mix VMG-600 and VM 20, but can be applied to Active Mix VMG-500 and VM 10. A mixture of formic and propionic acids (or rather, their salts) turned out to be chemically compatible with all of these feed additives. The effect of these preservatives on laboratory strains of St. aureus, B. subtilis and E. coli was studied. It was found that a mixture of formic and propionic acids has a bacteriostatic and bactericidal effect in lower concentrations compared to potassium sorbate. The storage periods of feed additives in non-sterile containers at room temperature and at +37 °C and the addition of a mixture of formic and propionic acids in concentrations from 0.2 to 0.7 % were estimated. At a concentration of 0.5 %, there were no signs of microbial growth during the year.

Objective: Coffee consumption is a prevalent habit with potential implications for ocular health. This study investigated the short-term effect of caffeine in coffee beverages on healthy subjects’ intraocular pressure (IOP).Material and Methods: Thirty subjects (10 males, 23.40±1.33 years) attended three visits at similar times. During each visit, subjects were asked to ingest either 250 ml of water, 250 ml of caffeinated coffee, or 250 ml of decaffeinated coffee within five minutes. The initial drink set was randomised. IOP was measured before ingestion (baseline) and at 0-, 5-, 10-, 15-, 20-, 30, 45-, and 60 minutes after each beverage consumption. Repeated measures of ANOVA and pairwise analysis were utilised to analyse the IOP difference within and between groups. Results: Baseline IOP across beverage groups were not significantly different (p-value>0.05). Water and caffeinated coffee groups showed a significant increase in IOP over time (p-value<0.0005), whereas decaffeinated coffee did not (p-value=0.437). The highest IOP values recorded were 16.09±2.41 mmHg for water and 15.22±2.26 mmHg for caffeinated coffee, 10 minutes and 15 minutes post-consumption, respectively. IOP spiked until minute 45 for the caffeinated coffee group but only until minute 20 for the water group. IOP in the water and caffeinated coffee groups returned to baseline levels by minute 30 and 60, respectively.Conclusion: Caffeinated coffee has a prolonged effect on increasing IOP compared to water. Additionally, low doses of caffeine, such as those found in decaffeinated coffee, may protect against IOP spikes. Further study is needed to investigate the long-term effect of coffee and caffeine consumption on ocular health.

As plantas estão sujeitas a estresses abióticos a qualquer momento, e estes afetam negativamente o crescimento e a produção de espécies de interesse agronômico, como o feijão-caupi. Neste contexto, o Silício (Si) surge como uma alternativa estratégica de manejo visando melhorar o desempenho das plantas em condições adequadas de cultivo, e principalmente, sob condições com restrições, devido a sua atuação potencializadora no desenvolvimento das plantas. No entanto, estudos em campo sob sequeiro que englobem elementos minerais benéficos no feijão-caupi ainda são incipientes. Nesse sentido, o objetivo do estudo foi avaliar a ação de diferentes doses de silício nos parâmetros de crescimento e produtividade de grãos de duas cultivares do feijão-caupi.  O estudo foi conduzido em campo sob condições de sequeiro, na Fazenda Experimental do IFPI- campus Uruçuí, no delineamento experimental de blocos ao acaso com quatro repetições, em esquema de parcelas subsubdivididas 2 x 4, as parcelas correspondendo as duas cultivares de feijão-caupi (BRS Novaera e BRS Tumucumaque) e as subparcelas constituídas por quatro doses de Si (0, 5, 10, 20 g ha-1). Foram avaliados os seguintes caracteres: altura da planta, massa seca da parte aérea, número de vagens por planta, número de grãos por vagem, massa de 100 grãos e a produtividade média de grãos. A aplicação de silício influenciou positivamente a altura de plantas e a produtividade média das cultivares. A cultivar BRS Tumucumaque apresentou um incremento de 59,97% na produtividade de grãos quando o Si foi fornecido na dose de 10 g ha-1, e a BRS Novaera teve um melhor comportamento quanto a produtividade de grãos na dose de 20 g ha-1, com incremento de 46,93%. Conclui-se que a suplementação com silício é uma estratégia promissora para melhorar o desempenho agronômico do feijão-caupi.

Avaliou-se as características fermentativas e a estabilidade aeróbica da silagem de sorgo granífero após a colheita dos grãos. A pesquisa foi desenvolvida na Universidade Federal Rural de Pernambuco – Unidade Acadêmica de Serra Talhada (UFRPE-UAST), sendo o sorgo plantado na área da Empresa Pernambucana de Pesquisa – IPA. O delineamento experimental foi inteiramente casualizado, com três tratamentos, sorgo 1G100 adubado com NPK, 1G100 sem adubo e XS9454 com adubo NPK e três repetições. Para a produção da silagem foram utilizadas mini silos experimentais de cano de PVC 0,10 x 0,50 cm e sacolas de 20 L.  Após 35 dias, os silos foram abertos e realizadas as seguintes análises: sensoriais (cor, odor e textura); MS, pH, perdas fermentativas e estabilidade aeróbica e submetidos à análise de variância e teste de média. As características sensoriais foram realizadas no momento da abertura dos silos, sendo a cor, odor e textura de todas as silagens caracterizadas entre boa e média. Houve efeito (P<0,05) para o teor de MS e pH da silagem.  A perda de gases e MS não diferiram (P>0,05) e foram consideradas adequadas ao padrão processo fermentativo. Após período de 240h (10 dias) de exposição ao ar os valores de pH entre as silagens não se diferiram (P>0,05), apresentando valores de 4,51, 4,40, 4,36 para 1G100 s/adubo, 1G100 c/adubo e XS9454/adubo, respectivamente, porém já era possível visualizar o crescimento de fungos. Conclui-se que as silagens foram classificadas como de boa a média qualidade em termos de teor de matéria seca, características sensoriais e fermentação. Nenhuma das silagens apresentou deterioração completa durante o período de estabilidade aeróbica de 240 horas observadas, mantendo-se, grandes partes estáveis ao longo desse período, o que permite melhor utilização da silagem.

A agricultura de precisão, a passos lentos, vem conquistando espaço no mercado agrícola, já que ela é capaz de tratar uma mesma lavoura conforme suas necessidades pontuais, e trazer melhor qualidade ao produto final, além de possibilitar o monitoramento, a todo instante, do processo produtivo. Entretanto, sua não adesão pelo produtor é, principalmente, em função do alto investimento inicial, no caso, com amostragens e mapeamentos para posterior tomada de decisão. Nesse sentido, o mapeamento da condutividade elétrica do solo vem com o intuito de reduzir os custos com os elementos citados acima, já que ela tem boa correlação com aspectos do tipo químico e físico do solo, permitindo que haja a subdivisão da lavoura em unidades de manejo, possibilitando análises mais acuradas, que, por consequência, diminui a quantidade de produtos necessários para o cuidado da lavoura. Dentro de todo esse escopo, objetivou-se com esse trabalho, validar o sistema portátil de coleta de dados de condutividade elétrica do solo diretamente em campo, desenvolvido pelo laboratório de Geoprocessamento e Agricultura de Precisão do IFMS (campus Nova Andradina) comparando dados com um equipamento comercial, além de levantar dados de uma área de pesquisa irrigada nas dependências do mesmo. Esse processo foi realizado por meio de modelagem e impressão 3D, realizados no Centro de Idiomas e Tecnologias (CIT), teste a campo com o intuito de verificar possíveis instabilidades no sistema, teste de validação do código, que gerou a equação de calibração e conversão dos dados obtidos em campo, e, por fim, o depósito da patente no INPI. Processos os quais foram concluídos, e como resultado foi realizado a solicitação de depósito de patente do software e do conjunto que a ele confere proteção e ergonomia, das quais estão em análise pelo NIT; foi obtido a equação de calibração, utilizada na correção dos dados obtidos a campo; o mapeamento de uma área de pesquisa do IFMS (campus Nova Andradina), o qual foi realizado juntamente com coleta de dados de NDVI, com a finalidade de analisar uma possível correlação, a qual, no presente trabalho não demonstrou significância. Com o trabalho, concluiu-se ser uma eficiente maneira de subdividir as unidades de manejo, além de ter um baixo custo de aquisição, quando comparado a outros equipamentos disponíveis no mercado, e ser um dos poucos capazes de realizar leitura diretamente em campo.

A biologia, diversidade e atividade dos microorganismos do solo está cada vez maior, principalmente com os que cumprem função na ciclagem de nutrientes ou produtividade dos ecossistemas. Esse estudo tem por finalidade caracterizar a variabilidade da colonização micorrízica em raízes coletadas em área de cultivo de mix de cobertura sob sistema de plantio direto, no cerrado Sul-Mato-Grossense e avaliar a influência das propriedades físico-químicas do solo na variabilidade espacial da biomassa microbiana encontrada no solo. O estudo foi realizado no campus do Instituto Federal de Mato Grosso do Sul em Nova Andradina/MS, onde foram coletadas 48 amostras de solo georreferenciadas, para realização da análise química (a matéria orgânica (MO), capacidade de troca de cátion (CTC), saturação de base (V%), fósforo (P), potássio (K)) e microbiológica do solo, para a análise de microbiológica foram utilizando cilindros de 50 mm de diâmetro a 50 mm de profundidade (4 amostras por ponto), sendo a avaliação da porcentagem de colonização pelo método da placa riscada. Os dados foram submetidos à análise estatística descritiva e análise geoestatística sendo realizada a interpolação pelo Inverso do Quadrado da Distância (IQD) e Krigagem, de acordo com a dependência espacial, utilizando o software QGis. Foi possível analisar a distribuição espacial da colonização micorrízica em raízes de plantas em área cultivada com soja e plantas de cobertura em sucessão no cerrado sul-mato-grossense, através dos mapas temáticos gerados. A porcentagem de micorrizas arbusculares no ano de (2022) e (2023) no solo foi considerado significativo, pode ser observado maiores porcentagens no ano de 2023, este fato pode estar relacionado com a diminuição do alumínio (Al) no solo, visualizado em 2023. A redução do alumínio também pode estar ligado ao aumento da concentração de macronutrientes no solo como potássio (K), enxofre (S) e micronutriente ferro (Fe), bem como com a implantação do mix de cobertura no ano de (2023). Nos mapas de variabilidade espacial de distribuição dos atributos analisados também é possível verificar que com a implantação do mix de cobertura, também aumentou a colonização micorrízica e os nutrientes, potássio (K), enxofre (S) e ferro (Fe), melhorando a microbiota do solo, podendo ser comprovado através da análise de correlação entre os atributos analisados.

Published: October 2024

Dieser Beitrag knüpft an Arbeiten aus dem Forschungsfeld Geschlechterverhältnisse und Nachhaltigkeit an und zielt darauf ab, intersektionale Geschlechterperspektiven als Heuristik zur Analyse sozial-ökologischer Transformationen zu formulieren. Dabei wird die in der geschlechterbezogenen Nachhaltigkeitsforschung entwickelte Unterscheidung von Geschlecht als Differenz-, Struktur-, Prozess- und epistemologische Kategorie insbesondere in Bezug auf intersektionale und epistemologische Perspektiven konkretisiert, die zu einem erweiterten, heuristischen Verständnis der Geschlechterperspektiven als Analyseperspektiven beitragen. Am Beispiel der Systematisierung von Forschungsarbeiten an der Schnittstelle von Energiewende, Geschlecht und Macht werden die Potenziale der jeweiligen Perspektiven und ihrer Erweiterungen konkretisiert. Damit wird sowohl die systematisierende als auch die analytische Funktion einer solchen Heuristik für die (empirische) Forschung zu sozial-ökologischen Transformationen verdeutlicht.
