Authors: Utebaeva Aidana , Gabrilyants Eleonora , Abish Zhansaya , Yevlash Viktoriia
Published: May 2024

Functional foods containing probiotics and/or prebiotics are of scientific and practical importance. The method of pre-activating bifidobacteria before their use in the production of fermented milk products has a profound impact on enhancing the quality of the resulting products. Finding ways to shorten the activation time of bifidobacteria in the production of functional foods with probiotics is an urgent task.
Shortening the activation time and optimizing enzyme systems of bifidobacteria with antioxidants are crucial for innovative probiotic fermented milk technology. The object of this research is the technology of fermented acidophilic products enriched with bifidobacteria activated using Prunus padus (bird cherry) extract, known for its antioxidant properties. The finished product showed a significant increase in bifidobacteria count, reaching 1×109 CFU, and a 25.7 % boost in L. acidophilus after 7 days.
Furthermore, the activation of bifidobacteria by Prunus padus extract resulted in a threefold increase in the histidine content and increased the content of oleic, eicosanoic, linoleic, arachidonic, and docosahexaenoic acids by 10.0 %, 26.4 %, 14.4 %, 22.6 %, and 66.6 % in the experimental sample compared to the control sample, respectively.  Moreover, pentadecanoic, selacholeic, eicosatrienoic acids and tyrosine were present in the experimental but not in the control sample. Microbiological safety tests found no pathogenic microorganisms in the fermented acidophilic product, yet lactic acid microorganism levels exceeded norms in the experimental sample, confirming the product's probiotic properties and high physiological value. Thus, the developed product is characterized by better taste, a longer shelf life, and the preservation of bacterial titers

Published: May 2024

This paper examines the working process of a belt conveyor with a working drive that can change the length of transportation. The conveyor can be used for tunneling, development of minerals in mines and quarries, transportation of materials in warehouses. The use of such a conveyor makes it possible to reduce the time for operations to increase or decrease the length of transportation, to exclude reloaders between the working equipment and conveyor itself from the transport chain.
It was established that when changing the length of transportation of a working conveyor, the static and dynamic load on the belt increases. The change in the static load of the belt on the drum of the mobile station depends on the speed of the mobile station and the speed of the beltgenerated by the conveyor drive. The dynamic loading on the belt depends on the acceleration of the belt, which is related to the acceleration of the mobile station during the change in the length of the conveyor.
For a working conveyor that changes the length of transportation, the static tension of the belt on the drum of the mobile station can increase by 1.1–1.4 times from the initial one. The dynamic loading of the belt can have a significant increase if the acceleration of the mobile station is not stretched over time and acquires large values.
Based on the dependencesderived in the current work, a calculation procedure is proposed for the design of a belt conveyor with a working drive that can change the length of transportation.
The Mathcad software was applied to verify the designcalculation procedure.
The results make it possible to employ new design methods in the construction of competitive machines equipped with a belt conveyor with a variable length of transportation

The object of this study is the financing mechanism for the development of local communities. The paper addressed the problem of improving this mechanism under conditions of limited resources through the use of digital technologies. The structure of the mechanism is represented as interconnected subjects, sources, methods, objectives, and technical infrastructure of financing. Local self-government bodies are the managing entity. Factors affecting the availability of financial resources, depending on the financing method, are the volume of resources, the orderliness of legislation and legal models, financial capabilities, and interests of financing entities. They also include legal restrictions on application, requirements of resource holders, their cost and duration of receipt. The crisis was recognized as a significant limiting factor. Identification of factors of accessibility and complexity makes it possible to identify weak points in the entire funding mechanism. The description of the theoretical concept of the financing mechanism due to its universality, the factors of the availability of financial resources and the shortcomings of the technical infrastructure, identified on this basis, made it possible to solve the investigated problem. As a result, directions for improving the financing mechanism for the development of local communities have been determined in terms of technical infrastructure. They consist in creating unified technical systems for managing financing processes and expanding training and support for financing entities. The use of artificial intelligence, big data, blockchain and tokenization technologies for decision-making, forecasting the needs of local communities and the development of crowdfunding is also proposed. Owing to this, it will be possible to achieve practical expectations for improving the effectiveness of the existing financing mechanism, which consists in reducing transaction costs, attracting additional financial resources, increasing public participation and transparency of financial processes

Published: May 2024

The object of this study is the process of estimation and control of an IT project.
During the study, the problem of increasing the accuracy of estimating the efforts of an IT project to build an information system (IS) was solved. Research in this area is aimed at simplifying the original assessment methods or at applying elements of artificial intelligence to these methods. The task of the impact of the features of IS development methodology on effort assessment remains unexplored.
During the study, the method of functional point analysis was modified. The proposed modification makes it possible to increase the accuracy of estimating efforts to build an IS under the conditions of re-using its individual functions. These conditions allow the construction of new system functions by reusing a previously developed function of the same system.
The developed method was tested during the evaluation of efforts of an IT project to form the functional task "Forming and executing an individual plan for a research and teaching staff member of the department." The option of re-using one of the functions of a task during the construction of two other functions of the same task is considered. For this option, the estimate was 72 function points (the estimate using the standard method was 144 function points).
The use of the results allows us to increase the accuracy in assessing the efforts of IT projects to construct IS under the conditions of applying the methodology of reuse of previously developed system elements. This, in turn, makes it possible to improve the accuracy of estimating time costs, personnel requirements, and financial costs for the implementation of IT projects for constructing IS.
The results obtained are used to solve the task of estimating efforts during the planning of IT projects for developing information systems and their software

The object of the study is the process of treatment of sunflower phosphatide concentrate using sodium chloride solution.
Hydration is a stage of oil refining. The waste of the process is a phosphatide concentrate, the disposal of which is dangerous to the environment. The concentrate contains valuable components – oil and phosphatides. An important task is to separate these components for effective use in various industries.
The process of extracting oil from phosphatide concentrate by hydration in the presence of sodium chloride solution was investigated. The influence of the concentrate treatment conditions on the oil yield was determined.
A sample of concentrate according to SOU 15.4-37-212:2004 (CAS 3436-44-0) was used: mass fraction of moisture and volatile substances – 2.8 %, mass fraction of phosphatides – 41.5 %. The concentrate was treated with sodium chloride solution with a concentration of (5–20) %. The hydration time was 25 min., the temperature was 45 °C, and the mass ratio of the sodium chloride solution to the concentrate was 1:1.
Conditions for the concentrate treatment were determined: the concentration of sodium chloride solution was 15 %, settling time was 5 hours. At the same time, the yield of oil was 86.9 %.
The parameters of the extracted oil were determined: acid value 2.8 mg KOH/g, peroxide value 3.2 ½ O mmol/kg, mass fraction of moisture and volatile substances 0.12 %. According to these indicators, the extracted oil corresponds to first-grade unrefined unfrozen sunflower oil according to DSTU 4492. The mass fraction of phosphorus-containing substances in terms of stearooleolecithin was 1.7 %, which slightly exceeds the standard value.
The research results make it possible to process hydration waste and obtain oil, which is a raw material for the products of many industries. This will help solve the problem of disposal of environmentally hazardous waste and improve the state of the environment

Authors: Mizanbekov Ilyas , Kalym Kabdyrahim
Published: May 2024

The study focuses on the grain-product subcomplex within the Republic of Kazakhstan, aiming to dissect and address the prevalent issues plaguing this sector. It identifies several challenges, including technological deficiencies, inefficiencies, and increased production risks.
There was a notable decrease in fixed capital investment in the agricultural sector in 2023, suggesting a shift in investment strategies or priorities, particularly with a significant reduction in food production investments. Agricultural exports in 2023, while showing a decrease compared to 2022, still represent a substantial economic activity. The capacity and utilization of grain storage facilities indicate a robust infrastructure capable of supporting the nation's grain production, with a considerable portion of storage capacity currently utilized and a significant amount of grain released in 2023.
Furthermore, the research delves into cross-border rail transport of crops, with Uzbekistan emerging as a regional leader in exports. This analysis, along with the examination of export activities and grain storage capacities, emphasizes the role of innovation and technological advancements in enhancing the agroindustrial sector's efficiency and competitiveness.
Optimization methods for modeling transport processes in agribusiness, such as digital technologies and intermodal transport, are proposed to address existing shortcomings.
The study's findings are distinguished by their complex approach to addressing the problems within the grain-product subcomplex. This approach, highlighting the practical application under local conditions, makes the results uniquely tailored to Kazakhstan's context, offering a pathway towards improved agricultural practices and sectoral growth

Authors: Ivanytsky Valentyn , Meshko Roman , Chychura Igor , Rjaboschuk Myhajlo , Tiutiunnykov Serhii
Published: May 2024

The control system for terrestrial two-axis devices for orientation to the Sun has been improved with a high-speed microcontroller operation algorithm. A geomagnetic sensor was introduced into the system to increase the reliability of monitoring the positioning of solar cells. The basis of the algorithm is a simplified astronomical and geographical model of the movement of the Sun in the celestial sphere. The control system automatically tracks the trajectory of the Sun and calculates its angular coordinates for the current moment of time on any day of the year and for any point on the globe. The derived equations of the simplified mathematical model are suitable for calculations of orientation angles to the Sun in real time on 8-bit microcontrollers with low computing power. The control system by AVR-328 microcontrollers was studied. It was established that the use of the algorithm when programming microcontrollers for two-axis orientation systems ensures high stability and reliability of the tracker`s functioning process. The technical parameters of the AVR-328 microcontrollers in the case of using the developed algorithm ensure that the control system performs one reorientation step in a time interval of less than 2 seconds, which ensures the minimum technical period of the reorientation process by the tracker drive mechanisms which is about 5 seconds. Deviations of the calculated orientation angle from the exact value do not exceed 3°, which corresponds to the relative accuracy of recording the solar radiation intensity, which is less than 0.3 %. The microcontroller program written according to the developed simplified algorithm occupies about 35 % of its memory. Therefore, the use of the developed algorithm frees up the resources of AVR-328 microcontrollers for performing additional data processing operations and automatic control over various additional devices related to the process of orientation to the Sun. In the case of solar energy, the algorithm ensures the use of about 98 % of the power of solar radiation
Evaluation of the operational curve for heat storage technology using n-octacosane/low-density as a binding material

Published: May 2024

Heat storage technology has a critical role for a number of applications involving renewable thermal energy (such as solar water heater). The application of wax (n-octacosane/OCT) as a medium for storing heat brings many positive influences for the system. However, the operational curve is undesirable for the OCT-based energy storage, which makes it necessary to use a binding material. The present work employed LD-class polymer (LDPE) and linear-LDPE as binding materials for OCT. The mixture is prepared through mechanical hot stirring, which comes into two categories: SOCT1 (OCT/LD) and SOCT2 (OCT/LLD). The assessment through the calorimetry method shows an increment in transition temperature for SOCT with a value of 2.1 °C and 5.5 °C. This contributes to the variation of fusion energy for solid-liquid change for both materials, which amounted to 132.05 J/g (SOCT1) and 113.4 J/g (SOCT2). Another assessment related to its chemical and structural phase demonstrates that SOCT has an identical structure to OCT, indicating that SOCT is mixed physically. At the operational level, SOCT is more optimal than OCT according to the indicator related to charge and discharge duration for energy exchange. SOCT1 demonstrates a short plateau line as the indication of a steady transition between 65.4–67.9 °C, while SOCT2 indicates the average heating rate, which is higher than for single OCT. The heat releasing curve for SOCT1 varies at a lower value between 1.92 °C/min and 0.77 °C/min, while SOCT2 has the lowest variation, which is only 0.17 °C/min. Moreover, the self-insulation for SOCT2 has the lowest rate, which is only 0.3 °C/min. The evaluation and analysis from this work show that SOCT is reliable to increase the operational curve of OCT and can be implemented for thermal systems

Published: May 2024

Probiotics have multiple beneficial effects on human health, including modulation of the immune system, inhibition of enteric pathogens, and prevention of metabolic disorders. Lactic acid bacteria (LAB) are the most common bacterial strains used for probiotic production. Among those, species belonging to the Lactobacillus acidophilus complex, especially L. gasseri, were well characterized and reported for probiotics. This study evaluated the potential probiotic characteristics of two L. gasseri strains (designed as VTCC 12791 and VTCC 12792) isolated from a pair of mother's breast milk and infant's feces. Both strains completely survived in the simulated gastric juice, highly tolerated the simulated intestinal juice (81-84%), strongly adhered to the HT-29 cell (23.5% for VTCC 12791 strain and 5.5% for VTCC 12792 strain), and had antagonistic activity against food-borne pathogens of Aeromonas dhakensis, Vibrio vulnificus, and Listeria monocytogenes, which demonstrated better beneficial properties than those of the commercial reference Lacticaseibacillus casei Shirota (LcS) strain. Additionally, both strains exhibited xanthine oxidase inhibitory activity (approximately 24%), which can lead to reducing serum uric acid. Regarding the safety aspect, the strains were sensitive to several antibiotics of ampicillin, vancomycin, tetracycline, chloramphenicol, erythromycin, and possessed alpha-hemolytic activity, which were similar to those of LcS strain. Our results suggested that L. gasseri VTCC 12791 and VTCC 12792 are potential candidates for producing probiotics and functional foods. Further in vivo studies are needed to prove their potential health benefits, especially in the treatment of hyperuricemia.

Kazimierza Kłósaka odczytanie i ocena stanowiska Pierre’a Teilharda de Chardin w kwestii powstania człowieka i jego natury
Authors: Maziarka Tomasz
Published: May 2024

Artykuł jest próbą odpowiedzi na pytanie, w jaki sposób Kazimierz Kłósak odczytywał i interpretował poglądy Pierre’a Teilharda de Chardin w kwestii powstania człowieka i jego natury. Ukazuje on, że chociaż krakowski filozof popularyzował w Polsce twórczość francuskiego przyrodnika, to jednak niekiedy z nim polemizował i swoiście go interpretował. Kluczowym zagadnieniem była próba zrozumienia aktu stworzenia przez Boga duszy ludzkiej w kontekście ewolucji. Odpowiedź Teilharda brzmiała, że dusza ludzka wykształciła się na drodze ewolucji, gdyż duch egzystował w pramaterii; odpowiednie złożenie materii wygenerowało zjawiska duchowe. Chociaż Kłósak próbuje obronić Teilharda przed zarzutem o materializm, ostatecznie nie udaje mu się ocalić go dla ortodoksji. Zgodnie bowiem z klasycznym twierdzeniem, określonym przez św. Tomasza z Akwinu i popieranym przez Kłósaka, dusza ludzka została stworzona z nicości własnej i nicości podmiotu (ex nihilo sui et subiecti). W ujęciu Teilharda dusza ludzka powstała z duszy zwierzęcej, a więc powstała z nicości własnej, ale nie z nicości podmiotu. Rozwiązanie Teilharda nie jest więc „stworzeniem” w ścisłym tego słowa znaczeniu. Na kanwie głównego wątku artykuł podejmuje ważne kwestie metodologiczne dotyczące badania problemu początków człowieka i stworzenia duszy ludzkiej.

Published: May 2024

Based on a sociological survey conducted within the framework of the Swiss-Ukrainian project, the article analyses the state of citizenship of Ukrainians through the prism of developing their patriotic attitudes. The authors make a theoretical attempt to combine the notions of «citizenship » and «patriotism» with a view to their mutual informative reinforcement in the new model of citizenship patriotism. It is determined that the most integrative potential for the successful completion of democratic transit in Ukraine is a model of citizenship patriotism, based on a high level of citizenship competence of individuals (which implies a well-grounded positive assessment of the national realities, the attitude of conscious fulfilment of civil duties and active position of citizens in the field of protection of public interest).

Abstract Objective: To compare information on highly complex radiological procedures—computed tomography (CT) and magnetic resonance imaging (MRI)—between the public and private health care systems, across the five regions of Brazil, in terms of the numbers of radiological devices and examinations performed, between 2015 and 2021. Materials and Methods: This was a descriptive time series analysis of secondary data in the public domain, available from the Information Technology Department of the Brazilian Unified Health Care System, an entity of the Brazilian National Ministry of Health (NMH) that is responsible for collecting and storing health-related information in Brazil. The analysis included the numbers of CT and MRI scanners; the volumes and types of examinations; the type of institution (public or private); the regions of the country; and the years (2015 to 2021). Results: Progressive increases in the numbers of CT and MRI devices, as well as in the volumes of examinations, were observed over the years in all regions of the country. The private sector showed higher rates of equipment acquisition and of growth in the number of examinations. However, the public health care system did not reach the equipment targets set by the NMH, whereas the private health care system surpassed those targets. A greater number of examinations were performed in the private sector than in the public sector. Conclusion: During the period evaluated, the public health care system did not meet the equipment or examination targets recommended by the NMH, in any of the regions of the country, unlike the private health care system, which exceeded both in all of the regions.

ABSTRACT Introduction: burns represent a pivotal component of trauma in Brazil, accounting for 2 million incidents and 2,500 deaths annually. Self-intentional burns are associated with a worse prognosis, larger burned surface area, higher infection rates, and death. The lack of studies on the issue of self-immolation raises epidemiological questions regarding Brazilian victims. This study aimed to investigate the profile of burn events associated with self-injurious behavior among Brazilian victims. Methods: this systematic review was performed according to PRISMA 2020 guidelines and evaluated the correlation between self-injurious behavior as a cause of burns in Brazilian victims and its epidemiological implications in the last 20 years (2003-2023). The MeSH terms “Burns”, “Self-Injurious Behavior”, “Epidemiology” and “Brazil” were queried in the PubMed/MEDLINE, SciELO, and Cochrane Library databases, and, after selection by inclusion/exclusion criteria, the most relevant studies were critically analyzed. Results: From 1,077 pre-selected studies, 92 were potentially eligible, resulting in 7 manuscripts incorporated in this review. From 3,510 burned victims assembled in the pool of selected studies, 311 cases displayed self-injurious behavior. Burned patients who attempted to burn their lives have a higher risk of death (p<0.05; RR=5.1 [3.2-8.1]) and larger burned surface area (p<0.05; MD=19.2 [10-28.2]), compared to accidental cases. Moreover, the female gender was at a higher risk of attempting self-immolation (p<0.05; RR=4.01 [2.9-5.5]). Conclusion: our results show that self-inflicted burn cases were associated with a larger burned surface area and a higher risk of death, and the female gender was identified as a relevant risk factor in Brazil.

Published: May 2024

ABSTRACT Introduction: Abdominal wall hernias encompass both ventral and incisional hernias, often poorly classified regarding complexity in general. This study aims to conduct a review on the primary topics related to defining the complexity of ventral hernias. Methods: this is a scope review conducted following the guidelines recommended by the PRISMA-ScR directive. Searches were carried out in electronic databases including PubMed, LILACS, and EMBASE, using the descriptors: Abdominal Hernia, Hernia, Ventral Hernia, Incisional Hernia, Complex, Classification, Classify, Grade, Scale, and Definition. Combinations of these terms were employed when appropriate. Inclusion criteria encompassed articles with definitions and classifications of complex hernias, as well as those utilizing these classifications to guide treatments and patient allocation. Synonyms and related topics were also considered. Articles outside the scope or lacking the themes in their title or abstract were excluded. The database search was conducted up to July 29, 2023. Results: several hernia classifications were identified as useful in predicting complexity. For this study, we considered six main criteria: size and location, loss of domain, use of abdominal wall relaxation techniques, characteristics of imaging exams, status of the subcutaneous cellular tissue, and likelihood of recurrence. Conclusion: complex abdominal wall hernias can be defined by characteristics analyzed collectively, relating to the patients previous clinical status, size and location of the hernia defect, status of subcutaneous cellular tissue, myofascial release techniques, and other complicating factors.

Published: May 2024

ABSTRACT Introduction: fat embolism syndrome (FES) is an acute respiratory disorder that occurs when an inflammatory response causes the embolization of fat and marrow particles into the bloodstream. The exact incidence of FES is not well defined due to the difficulty of diagnosis. FES is mostly associated with isolated long bone trauma, and it is usually misdiagnosed in other trauma cases. The scope of this study was to identify and search the current literature for cases of FES in nonorthopedic trauma patients with the aim of defining the etiology, incidence, and main clinical manifestations. Methods: we perform a literature search via the PubMed journal to find, summarize, and incorporate reports of fat embolisms in patients presenting with non-orthopedic trauma. Results: the final literature search yielded 23 papers of patients presenting with fat embolism/FES due to non-orthopedic trauma. The presentation and etiology of these fat embolisms is varied and complex, differing from patient to patient. In this review, we highlight the importance of maintaining a clinical suspicion of FES within the trauma and critical care community. Conclusion: to help trauma surgeons and clinicians identify FES cases in trauma patients who do not present with long bone fracture, we also present the main clinical signs of FES as well as the possible treatment and prevention options.

Published: May 2024

RESUMO Este estudo investiga a interação em serviços entre estudantes universitários e funcionários, explorando seu impacto na identificação do estudante com a universidade e o boca a boca positivo resultante dessa identificação. Utilizando teorias de identidade social, impacto social e a perspectiva de cadeia serviço-lucro, a pesquisa analisa como a percepção do consumidor em relação a um grupo social, ou sua identificação, influencia seu envolvimento voluntário nos serviços. Uma pesquisa descritiva e quantitativa, com 229 estudantes de duas universidades brasileiras, foi conduzida. Os dados foram fundamentados na técnica de modelagem de equações estruturais baseadas na covariância. Os resultados destacam que a interação com funcionários e a percepção de outros clientes têm impacto positivo na relação estudante-universidade. O estudo confirma que o boca a boca é explicado pela identificação do consumidor com a universidade, sustentando essa relação sob uma perspectiva unidimensional. Além disso, os resultados fortalecem as conexões do construto identificação consumidor-empresa no contexto de serviços, enriquecendo a validade externa ao ser avaliado no ambiente de ensino superior.

Por um método materialista, propomos compreender a figuração literária do arquivo não como uma tendência do século XIX que nasce da necessidade de instituir um regime discursivo de verdade na literatura, mas sim como mecanismo propício à representação literária de uma sociabilidade burguesa recém-consolidada. Para isso, colocamo-nos em diálogo com as análises feitas por Codebò em Narrating from the Archive de dois “romances de arquivo” do século XIX: O Coronel Chabert, de Balzac, e Bouvard e Pécuchet, de Flaubert.
The poetic, the prophetic, and the pathetic in “Pelas Tabelas”, by Chico Buarque

Published: May 2024

Abstract This paper presents an analysis of the song “Pelas Tabelas”, by Chico Buarque, and explores its main allusion: the Biblical figure of John the Baptist as a symbol of resistance to tyranny, violence, and irrationality. Buarque uses poetry, irony, and references to Brazilian culture in order to create a story of love and alienation with pathetic intensity. The paper contextualizes the song in the context of Buarque’s musical oeuvre and in that particular political moment in Brazilian history - the 1980s - in which a great movement for the reestablishment of democracy was on its way: the movement called Diretas Já. This analysis proposes a dialogue with the fields of cultural studies, theology, and literature. It shows that Buarque’s song is imbued with the poetic, the prophetic, and the pathetic.

Abstract Purpose: This study aimed to analyze the influence of human values on impulse buying behavior and whether this influence differs between genders. Originality/value: The research contributes to the understanding of the relationship between the values individuals prioritize and their impulsive buying behavior. The results can offer guidance to professionals and business managers in conducting their sales strategies and to researchers when considering human values in investigations of buying behavior, enabling new understandings. Design/methodology/approach: A model with two scales, impulsive buying and human values, consolidated in the Brazilian context, was applied, resulting in 414 responses analyzed through structural equation modeling. Findings: The results demonstrated that human values affect impulsive buying behavior, indicating that the values of pleasure, emotion, and religiosity have a positive relationship, and the values of health and knowledge have a negative relationship. Samples by gender presented significant differences, as survival and emotion have a greater positive influence on impulsive buying in men, while women are more influenced by the pleasure and emotion values and have a negative relationship with the affectivity value.

ABSTRACT Objective To describe and analyze the donor mothers’ profile and variables associated with breast milk donation at Human Milk Bank in the municipality of Guarapuava, Paraná, Brazil. Methods This was a cross-sectional study obtained from information contained in the donor registration form between the period July 2013 (implementation of the service) to December 2019. The collected data were tabulated and descriptive analysis of variables and Chi-square and Fischer’s exact association tests were performed. Results Of 1,491 records analyzed, this research identified that 70.73% of donors were between 20 to 34 years old; 67.69% had prenatal care at public health network and 61.37% have had cesarean delivery. Most mothers (61.44%) remained as donor for 29 days and 53.83% of them donated up to 500 ml of milk. In addition, statistically significant association was observed between milk volume donated and donation time for the following variables: prenatal place care, gestational age, child's birth weight, child age, and smoking. Maternal age was associated with a higher volume of donated milk. Conclusion The study's findings reinforce the approaching importance the possibility of human milk donation during prenatal care, with emphasis on private health service, and throughout the women's and children's health care network, as well as on the community.

Neste trabalho, foi desenvolvida uma estação meteorológica automática e de baixo custo utilizando materiais reaproveitados e sensores de baixo custo, conectada ao site de visualização e gerenciamento de dados Ubidots. A estação conta com sensores de temperatura (AHT10), umidade (AHT10), pressão (BMP180), radiação solar (LDR), um pluviômetro e um anemômetro digital, ambos feitos com materiais reaproveitados e de fácil acesso, tendo sido o anemômetro desenvolvido com uma ventoinha (sensor hall) e o pluviômetro baseado num sensor magnético reed switch. Todo o sistema é conectado à placa de prototipagem eletrônica ESP8266, a qual já possui um módulo que permite a conexão com a internet. Todo o dispositivo foi custeado com cerca de 50 reais. Os sensores de temperatura, umidade e o anemômetro foram calibrados utilizando sensores padrão para garantir uma medição precisa. Os valores de umidade e temperatura foram então comparados aos dados obtidos por uma estação profissional próxima. O pluviômetro também passou por uma calibração para medir a quantidade de chuva em milímetros. Além disso, foram implementadas previsões baseadas em modelos para estimar o ponto de orvalho, pressão de vapor d’água, água precipitável e sensação térmica, fornecendo informações adicionais sobre as condições do tempo local.

As doenças cardiovasculares lideram a causa de mortalidade no mundo. O eletrocardiograma é uma das formas de obter o diagnóstico relacionado a doenças cardíacas. O exame consiste no registro da atividade elétrica do músculo cardíaco por meio de eletrodos posicionados nos braços, pernas e tórax do indivíduo. Neste trabalho estudamos o modelo de McSharry, que é capaz de reproduzir os sinais característicos do eletrocardiograma usando três equações diferenciais acopladas. Adicionando ao modelo um ruído e um termo senoidal, verificamos que essas modificações permitem alterar a característica do sinal de eletrocardiograma. Mostramos que é possível gerar sinais semelhantes àqueles que caracterizam anomalias no sistema cardiovascular. Utilizamos exames reais reportados pela Sociedade de Cardiologia do Estado do Rio de Janeiro para comparar com os resultados das simulações.
A charcoal frontier: the steel industry and forest in twentieth-century Minas Gerais (Brazil)

Abstract Focusing on the charcoal-fired steel industry in the Doce River Valley (rural eastern Brazil), this article sets out to understand the relationship between industrial-scale mining and the transition from iron factories to large steel mills. At the same time, it addresses the further destruction of the Atlantic Forest. Studies on the steel industry that highlight the pressure exerted on the Atlantic Forest by charcoal plants are almost nonexistent, however. Turning to technical reports, official statistics, journals, and other media sources and centering attention on Belgo-Mineira company, it highlights a set of data that enables us to measure the impacts of the charcoal-fired steel industry on forests. In order to get a deep insight, the main aim was to estimate the amount of forest extraction to serve the steel industry from 1936 to 1954. The data from this research show that the charcoal-fired steel industry gave a distinctive cast to the phenomenon of the agricultural frontier.

Published: May 2024

Abstract This paper examines the quality of life of organic and conventional soybean farmers in Brazil. We analyzed self-reported symptoms associated with exposure to pesticides and measured life satisfaction levels of the farmers. We applied three models to analyze the data according to the dependent variable distribution - dichotomy, Poisson, and ordinal. Questionnaires were applied to 62 and 139 organic and conventional soybean farmers, respectively. We found that the probability of organic farmers to report symptoms related to pesticides exposure was 59% lower than conventional farmers; and organic farmers had a 68% higher odds ratio for life satisfaction compared to conventional farmers. We conclude that organic soybean production has improved the quality of life for agricultural workers, while also enhancing the sustainability of rural areas.

Abstract This article scrutinizes the National Policy on Solid Waste (PNRS) - Law 12.305/2010 regarding the collective and diffuse rights of collectors of recyclable materials. More than a decade since the enactment of the PNRS, the rights bestowed by this legislation have yet to be actualized. In its analysis, the article highlights public-interest civil actions pertaining to the cities of São Paulo (SP), Rio de Janeiro (RJ), and Brasília (DF). The hypothetical-deductive method was employed within a qualitative framework, utilizing both bibliographic and documentary research tools. It is concluded that, due to governmental neglect, there is an imperative for the ongoing involvement of the Public Prosecutor’s Office and the Public Defender’s Office to advocate for and safeguard the rights of this worker category, which are pivotal in the advancement of a sustainable environment.
