Authors: Da Silva Teixeira Gibran , Drevnovicz Silveira Gabriela , Halmenschlager Vinícius
Published: October 2024

O presente estudo tem por objetivo avaliar a relação entre os gastos alocados em educação e índices educacionais em nível municipal no estado do Rio Grande do Sul, no período de 2005 a 2015. Nessa perspectiva, busca-se analisar a relação do gasto com métricas específicas de infraestrutura da educação e de qualidade educacional no município.  Para tanto foi construído um painel de dados municipais de gastos direcionados à Educação, do Índice FIRJAN de Desenvolvimento Municipal (IFDM - Educação) e do Índice de Desenvolvimento Socioeconômico (IDESE), dentre outras variáveis de controle. A partir dos resultados estimados foi possível identificar uma relação estatisticamente positiva entre a proporção de gastos em educação e melhores índices educacionais, medido através do índice IFDM-Educação. Além disso, se verifica que o gasto está positivamente relacionado com a infraestrutura educacional e não apresenta relação estatisticamente significativa com a qualidade da educação no município, medidos através de indicadores do IDESE.

Authors: Carniello Monica Franchi , Dos Santos Moacir José , Calderaro da Silva Nelson Marcos
Published: October 2024

A Região Metropolitana do Vale do Paraíba   (RMVPLN), formada por 39 municípios, foi criada em 2012. A pesquisa tem como objetivo avaliar a sustentabilidade da RMVPLN, por meio da aplicação da ferramenta Barômetro da Sustentabilidade (BS) em duas fases distintas, antes e depois da criação da região metropolitana por lei. Quanto ao método, a pesquisa caracteriza-se como documental, com modelagem descritiva e uma abordagem quantitativa nas análises. Foi possível demonstrar que os municípios da RMVPLN são heterogêneos quanto às suas características e, como região, não atendem plenamente aos requisitos de formação das regiões metropolitanas. Quanto à sustentabilidade da região, embora tenha avançado um pouco, ainda se encontra na escala de quase insustentabilidade. Conclui-se que, na primeira década de metropolização, não houve avanços significativos no consolidado dos índices do bem-estar do ecossistema e no bem-estar humano na perspectiva regional. Quando analisados individualmente, os municípios apresentam resultados distintos quanto à sustentabilidade.
O Rural nos instrumentos de planejamento territorial: o caso dos municípios do COREDE Norte do RS
Authors: Oliveira Daniela , Alexandre Bariviera Cassio
Published: October 2024

Mesmo sendo maioria no território brasileiro, as regiões rurais e os municípios de pequeno porte populacional são frequentemente desassistidos pelo poder público no que se refere ao planejamento territorial, ficando à mercê de instrumentos básicos e generalistas, normalmente direcionados as áreas urbanas, ou elaborados para grandes centros urbanos. Dadas as mudanças ocorridas na trajetória do planejamento territorial no Brasil, principalmente no que se refere ao período pós Constituição Federal de 1988, e ao Estatuto da Cidade, este trabalho se propõe a investigar se e como o rural tem sido tratado pelos instrumentos de planejamento territorial dos 32 municípios do Corede Norte-RS. Para isso realizou-se  uma pesquisa documental nos instrumentos de planejamento e  leis orgânicas dos municípios em análise (obtidos em sítios digitais das prefeituras municipais e em repositórios de legislações disponíveis na internet). Os documentos foram catalogados e posteriormente analisados, a fim de identificar elementos relacionados com as questões e hipóteses previamente estabelecidas. Observou-se a predominância de instrumentos básicos da política urbana em praticamente todos os municípios analisados, os quais, além de perpetuarem noções exclusivamente urbanas para o planejamento, e exclusivamente agrícolas para o espaço rural, relegam o espaço rural a outras normativas federais, por vezes, orientadas por instituições diversas (Incra, Conama, Código Tributário, etc.) e que não chegam na escala local do planejamento. Nos casos onde o rural foi incluído pelos instrumentos de planejamento dos municípios, estes seguem atrelando-o a ótica de oposição à cidade e atribuindo-lhe apenas uma destinação agro-silvo-pastoril.
Desigualdades regionais na Alemanha: evolução e fatores associados ao processo de convergência
Authors: Cavalcante Luiz Ricardo
Published: October 2024

Desde a reunificação do país no início da década de 1990, a Alemanha vem adotando uma série de políticas públicas para equalizar os padrões de vida em seu território. Neste trabalho, descreve-se a evolução das desigualdades regionais na Alemanha e discutem-se, com base em documentos oficiais e em artigos acadêmicos, os fatores associados ao processo de convergência observado ao longo dos últimos trinta anos. Os documentos analisados indicam que, nesse período: i) houve um processo de convergência entre as regiões correspondentes às antigas Alemanha Ocidental e Alemanha Oriental; ii) ainda persistem desigualdades regionais na Alemanha; e iii) o processo de convergência, embora contínuo ao longo de todo o intervalo, foi mais acelerado nos primeiros anos após a reunificação. Em um primeiro momento, a eliminação de barreiras aos fluxos de capital e de pessoas e os subsídios aos investimentos na antiga Alemanha Oriental motivaram uma acentuada redução das desigualdades. A partir de então, políticas de abrangência nacional com impactos regionais assimétricos e políticas regionais explícitas contribuíram para a redução das desigualdades regionais. Argumenta-se que alguns elementos observados na Alemanha podem servir de referência para o Brasil, onde os níveis de desigualdades regionais são elevados e resilientes há muitas décadas.
Rayleigh Quotient and Surjectivity of Nonlinear Operators in Hilbert space
Authors: Raffaele Chiappinelli
Published: October 2024

We consider continuous operators acting in a real Hilbert space and indicate conditions ensuring their continuous invertibility and/or surjectivity. In the case of bounded linear operators, these facts are well-known from basic Functional Analysis. The objective of this work is to indicate how similar properties can be proved also when the operators are not necessarily linear, using as a main tool their Rayleigh quotient and especially its lower and upper bound. In particular, we focus our attention on gradient operators and show a quantitative criterion that ensures their surjectivity through the positivity of an additional constant related to the measure of noncompactness.

Published: October 2024

This study protocol outlines a research project aimed at investigating the two assessment tools for post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) based on the ICD-11 framework: the International Trauma Interview (ITI) and the International Trauma Questionnaire (ITQ). The study is conducted at two specialized outpatient clinics in Denmark, focusing on trauma-affected civilians and refugees. With a sample size of 100 participants, equally divided between the two clinics, the study has three primary objectives: (1) to assess the feasibility of implementing the ITI in clinical settings by evaluating clinician time expenditure and clinical utility; (2) to determine the prevalence and diagnostic consistency of ICD-11 PTSD and CPTSD as measured by the ITI and ITQ; and (3) to compare the two study populations on various sociodemographic and clinical variables, including trauma history, mental health symptoms, and functional outcomes. This study employs a mixed-methods approach, integrating quantitative data collection through standardized measures and qualitative insights from clinician focus groups. Results will contribute to the growing body of evidence on PTSD and CPTSD diagnosis, providing insights into the clinical utility of the ITI and the ITQ for diverse trauma-affected populations.
A Classification of Features for Interpersonal Disconnectivity in Digital Media: Block, Unfriend, Unfollow, Mute, Withhold, and Eject
Authors: John Nicholas
Published: October 2024

This article presents for the first time a classification of, and lexicon for, features for dissolving interpersonal ties in digital environments: blocking, unfriending, unfollowing, muting, withholding, and ejecting. There are two main motivations and two main contributions. The first motivation is that analyses of social media features have not included treatment of features for interpersonal disconnectivity; the second is that analyses of interpersonal disconnectivity have not included reference to the features that enable it. The two main contributions are the disambiguation of a confusing terminological field, thus making it possible to analytically distinguish between types of feature, and an intervention in the question of whether the features described in the article concern filtering information or avoiding people. Data were collected from 37 social media platforms and other services that enable digitally-mediated communication. Features for interpersonal disconnectivity were documented and then the features were grouped based on five questions about their use, where A is the person using the feature, and B is the target of A’s use of the feature: (a) Does it affect A’s feed?; (b) does it affect B’s feed?; (c) is A still connected to B?; (d) is B still connected to A?; (e) can A and B see each other’s profile?

Published: October 2024

Early-onset neonatal sepsis (EОNS) is one of the most severe diseases of the neonatal period and is often coupled to extremely unfavorable outcomes. In many ways, the severity of the condition and the results of newborn nursing depend on the etiology of the bacterial process. The major EОNS pathogens are traditionally considered to be Streptococcus group B and E. coli, much less common are other Gram-negative bacteria including casuistic cases caused by caused by Proteus mirabilis (P. mirabilis). The article provides a review on the P. mirabilis role in developing neonatal sepsis with pathogen-specific disease course and outcomes. In addition, we describe a clinical case of P. mirabilis-caused EОNS not only primarily characterized by the rarity of its causative agent, but also that it proceeded with a more favorable brain damage in contrast to similar cases described worldwide and because the neonatal EОNS developed in one of triplets, with two other babies being asymptomatic despite that P. mirabilis was also detected.

Published: October 2024

Considering evacuation from cramped interiors with aisle seats, the initial seating positions of pedestrians represent a non-negligible source of variance in total evacuation time. By means of Pathfinder simulations, this uncertainty is quantitatively investigated for a train and lecture hall geometry with homogeneous and heterogeneous groups of agents. Furthermore, an energy-inspired description of the occupation configuration is introduced that enables a proper numerical representation of the configuration space of the initial seating positions.

Authors: Vyrupaeva Ekaterina V. , Semenova Natalya V. , Kolesnikova Lubov I.
Published: October 2024

Pregnancy and menopause are critical periods in a woman’s life. Due to physiological changes in the neuroendocrine system regulation, susceptibility to respiratory viral infections increases in these periods, while affecting all organs and systems of the human body.
The aim of this review was to analyze the literature data on the effect of acute respiratory viral infections on neuroendocrine regulation in women during pregnancy and menopause. We reviewed full-text publications in the public domain from the PubMed, eLibrary.ru, and Google Scholar databases with a coverage period of more than twenty years (2000–2023).
Disruptions of the progesterone and estrogen production during infection with the influenza A (H1N1) and influenza B viruses have been shown in experimental studies. Hormonal status changes in pregnant women are detected during infection with the influenza A virus (H3N2) and depend on antiviral antibody titers and the presence of fetoplacental insufficiency. Pregnant women with COVID-19 may experience changes in the brain structure activities, as indicated by a high frequency of those in olfactory sensitivity and psychoemotional disorders. During menopause, infection with the SARS-CoV-2 virus leads to changes in the production of thyroxine, prolactin, estradiol, testosterone, cortisol, 17-hydroxyprogesterone, and dehydroepiandrosterone sulfate.
Retinoic acid receptor alpha expression in endometrioid heterotopias and the endometrium of patients with endometriosis
Authors: Seyidova Chimnaz I. kyzy , Yarmolinskaya Maria I.
Published: October 2024

BACKGROUND: Vitamin A is a fat-soluble compound, which is a biologically inactive food form and undergoes transformation by cytosolic alcohol dehydrogenases and microsomal retinol dehydrogenases into retinaldehyde, followed by oxidation by retinaldehyde dehydrogenases 1, 2 and 3 into retinoic acid. All-trans-retinoic acid has been identified as an active metabolite of retinoic acid, indirectly participating in various processes: differentiation, proliferation and apoptosis. Based on a number of studies, the role of retinoic acid and its receptors in various diseases has been proven. For example, the destruction of the RAR-β gene by the integration of the hepatitis B virus into its loci can be a factor in the development of human hepatocellular carcinoma. Subsequently, it was described that the characteristic point of interruption of translocation t(15:17), observed in acute promyelocytic leukemia, was located at the locus encoding retinoic acid receptor-α. As a result, in patients with acute promyelocytic leukemia, complete remission of the disease could often be achieved by treatment with high doses of all-trans-retinoic acid. Existing data on the ability of retinol to influence the processes of differentiation, proliferation, and apoptosis indicate that retinol may be involved in the pathogenesis of endometriosis, but the mechanisms of its effect on the disease are subject to further study.
AIM: The aim of this study was to evaluate the retinoic acid receptor alpha expression in endometrioid heterotopias and the endometrium of patients with different endometriosis stages according to the Revised American Society for Reproductive Medicine classification.
MATERIALS AND METHODS: This was a prospective study to determine the retinoic acid receptor alpha expression in the endometrium and endometrioid heterotopias of patients with endometriosis (n = 28) and of the control group (n = 10).
RESULTS: The retinoic acid receptor alpha expression in endometrioid heterotopias was lower compared to the eutopic endometrium of patients with endometriosis and the endometrium of patients in the control group by 3.4 and two times, respectively (p 0.001; the Kruskal – Wallis method).
CONCLUSIONS: The data obtained indicate the involvement of retinol in the pathogenesis of endometriosis. Despite the relative increase in retinol level in the peripheral blood and peritoneal fluid in patients with endometriosis compared to the control group, shown in our previous studies, the reduced retinoic acid receptor alpha expression in endometrioid heterotopias does not allow for full binding of vitamin A to the receptor and is accompanied by its improper metabolism.

Published: October 2024

Pot-pollen, a probiotic processed by stingless bees, has gained attention for its nutraceutical properties and pleasant sour taste. The aim of this editorial is to illustrate the state-of-the-art of pot-pollen research with a bibliometric overview using the Scopus database to value the experimental bioactivity (antimicrobial, antioxidant, anti-inflammatory, and anticancer) of pot-pollen, and the standards for quality control and safety of pot-pollen legislation, considered mandatory for clinical applications of this highly variable natural product. The bibliometric analysis since 2014 revealed a growing interest in pot-pollen research, with a focus on the following academic disciplines: Agricultural and Biological Sciences, Engineering, Biochemistry, Genetics and Molecular Biology, and Environmental Science. Nevertheless, the lack of medicine in subject areas and clinical research in medical journals, indicates a necessity for further studies on the potential applications of pot-pollen in human health. In conclusion, pot-pollen emerges as a bioactive material with health benefits, and a novel synergism with antibiotics reveals its therapeutic anti-antimicrobial-resistance (anti-AMR) potential, deserving further research to fully elucidate its potential in modern medicine.
Depolarization effects when receiving radio waves on a moving object for various types and characteristics of the path
Authors: Bondar P.I.
Published: October 2024

Depolarization is a change in the plane of oscillation of the vector of an electromagnetic wave during its propagation. It is important to take into account the depolarization of electromagnetic waves when designing a radio path, since each component (vertical and horizontal), depending on the propagation conditions, will have its own attenuation coefficient. In this regard, the choice of one or another type of polarization (linear, circular and elliptical) for a specific radio path will have a significant impact on the level of the received signal. In the course of this work, the most significant factors leading to the depolarization of electromagnetic waves along the propagation paths were identified. These factors included: scattering on bodies of suburban terrain (ground, forests, etc.), reflections (in combination with multipath propagation) from bodies of urban terrain, random (inclined) position of the antenna mobile terminal, Faraday rotation and dispersion in precipitation. As a result of the analysis of depolarization factors, mathematical models were formed that, due to their applied nature, made it possible to predict the effect of depolarization on the quality of reception by a subscriber station installed on a moving object, and also showed the relevance of using antenna systems with automated polarization adaptation.

Published: October 2024

Metamaterial structures are currently being used to reduce the mutual influence of antennas and antenna arrays of different frequency ranges. In this work, the authors carried out studies of metamaterial screen designed for a resonant frequency of 900 MHz. The purpose of this work was the synthesis and theoretical studies of the characteristics of a screen made of chiral metamaterial in the cellular radio range. The results of studies were obtained to determine the natural resonant frequency of metamaterial screen when it is excited by a plane wave and a half-wave dipole. Frequency dependences of the isolation between two dipoles in the presence of metamaterial screen and without it were also obtained. It is shown that a metamaterial screen at the established resonant frequency provides an isolation of 25 dB. The screen synthesized and studied in this work can be used to reduce the influence of cellular radio antennas on other antennas present on a complex telecommunications objects.

Published: October 2024

To reduce the radar signature of moving objects, such as cars, boats, manned and unmanned aircraft systems, technologies for creating broadband radio-absorbing materials are being actively developed and improved. Among such materials are composites and chiral metamaterials, which have unique characteristics that make it possible to effectively control the reflection and rotation of the plane of polarization of electromagnetic waves. In addition, devices included in the structure of infocommunication systems are subject to electromagnetic radiation, which can cause undesirable effects and interference. Radio-absorbing coatings based on metamaterials can significantly reduce the reflection of electromagnetic waves and effectively counteract the effects of electromagnetic radiation. The purpose of this study is to solve the scientific and technical problem of determining the reflection coefficients of electromagnetic waves from a radio-absorbing material consisting of a chiral metamaterial located on a conducting surface. The main objective of the work is to study the interaction of a plane electromagnetic wave with the specified layer of metamaterial located on a conducting plane, taking into account the inhomogeneity and dispersion of material parameters.

Analysis of two-dimensional planar gratings and metasurfaces in the quasi-static approximation
Authors: Akhiyarov V.V.
Published: October 2024

Currently, composite materials based on metal gratings with a period D much smaller than the wavelength l are widely used. With the use of such materials, it is possible to control the amplitude, phase and polarization of an electromagnetic wave, which opens wide possibilities for the creation of new types of antennas, radio-absorbing coatings, etc. This paper considers gratings of metallic strip or patches on the surface of a thin metal-backed dielectric slab to control the phase of the reflected wave. In the quasi-static approximation, the input impedance of such materials can be calculated using simple analytical formulas. This paper investigates the accuracy of the quasi-static approximation at different angles of incidence of the electromagnetic wave on two-dimensional gratings. Using the equivalent circuits method, analytical expressions for the input impedance of metasurfaces are obtained. The dispersion properties of composite materials “inductive or capacitive grating on the surface of a thin metal-backed dielectric slab” are investigated, and a technique for determining the resonant frequency, which corresponds to the maximum of the input impedance of the metasurface, is presented. The obtained results show that at any angle of incidence, it is possible to evaluate the condition of the quasi-static approximation applicability for two-dimensional gratings and for metasurfaces based on such gratings. If this condition is satisfied, that simple analytical expressions can be used to calculate the input impedance. The use of these expressions allows us to determine the frequency at which the input impedance reaches its maximum. It is established that for inductive and capacitive gratings the impedance boundary condition of M.A. Leontovich is equivalent to the averaged boundary condition of M.I. Kontorovich. It is obtained that for grating in free space, quasi-static approximation corresponds to the M.A. Leontovich impedance condition. The dispersion properties of composite materials “inductive or capacitive grating on a thin metal-backed dielectric slab” are investigated. It is shown that the phase transition of the reflection coefficient through zero occurs at maximum values of the input impedance. Using the considered method of equivalent circuits, the presented results can be easily generalized to any type of multilayer metasurfaces.

Propósito/Contexto: como propuesta transhumanista, los implantes neurales generan un binomio cerebro-dispositivo que, desde la libertad morfológica, se considera como un derecho a ser sujetos y al mismo tiempo medios y protagonistas de las propias transformaciones; sin embargo, se presentan inquietudes de cómo se interpreta la libertad morfológica con el uso de estos dispositivos.
Metodología/Enfoque: con base en cinco casos ficticios, se realiza un análisis de las connotaciones que tienen los implantes neurales desde la libertad morfológica como postura transhumanista, entendida especialmente con base en los planteamientos de Anders Sandberg. Resultados/Hallazgos: la libertad morfológica proporciona una mirada de la autonomía que dota de contenido al uso de los implantes neurales como propuesta transhumanista. Los desafíos que emergen implican reflexiones a situaciones como el hackeo, la privacidad de la información, el rendimiento personal, el uso militar y la misma identidad de las personas.
Discusión/Conclusiones/Contribuciones: como en otras neurotecnologías, los avances con los implantes neurales son progresivos, diversos y parecieran no tener límites, lo que aumenta las posibilidades de exploración en la procura del mejoramiento. Estas innovaciones también interpelan a la libertad morfológica, vistas desde un sujeto que al mismo tiempo se convierte en objeto para lograr el mejoramiento.
The Effects of Health Insurance on Demand for Healthcare Services in Tanzania
Authors: N.E. Kubetta , P.S. Omary , V.J. Mugula,
Published: October 2024

ABSTRACT: Consistent healthcare financing systems within a particular nation or community have been regarded as vital for making universal healthcare access. This study intended to examine the influence of health insurance on the demand for healthcare services and the influence of socio-economic, demographic and hospital-related factors on demand for health care services in Tanzania context. The study employed secondary data, which were analysed by descriptive statistics and the results were presented in tables and percentages. Econometric analysis was also done using binary probit regression model to determine the factors influencing demand for health care services in Tanzania.  The instrumental variable was applied to address the problem of endogeneity of health insurance. The regression results revealed that gender, education level, household size, income, treatment cost, perceived health quality and health insurance type were significant and positively linked with demand for health care services. However, marital status was also significant but negatively associated with the demand for healthcare services. The study concluded that, despite of the efforts made by the government and other stakeholders on emphasis over having health insurance, the enrolment to health insurance schemes is still low although it has been noted to significantly influence the demand for health care services. Lastly, the paper recommends that the government and other stakeholders are required to formulate or strengthen the formulated policy in practice, purposively to improve access, affordability and the quality of health care services. Governmental and non-governmental organizations (NGO`s) and other stakeholders should put more effective strategies to improve coverage but also reduce the financial burden caused by illness. Also, the government needs to subsidize the healthcare sector, especially to the poor and provide subsidies to private healthcare facilities, improvement of insurance type, specifically, the NHIF which needs to increase coverage. Furthermore, health care managers should educate other people and make a clear observation on factors that make individuals demand for health care because they have a great role in the health care sector as well as strategies to improve household`s income to meet the health needs in Tanzania.

Published: October 2024

Museums preserve and present valued historical artifacts, information, and displays to an information-hungry tourism market. As such, they play a crucial role in the tourism industry, serving as pertinent leisure attractions in many destinations. It is therefore important for management to identify the key determinants that lead to tourist satisfaction and to tourists’ intention to return in future. This knowledge could assist management in making the informed strategic decisions for sustaining such attractions. Very little research has been conducted on this aspect in terms of museums in South Africa, leaving numerous unanswered questions about tourists’ experiences, the perceived quality of sites and tourists’ satisfaction with sites, which ultimately impact their intention to return. A quantitative survey was conducted at the Stevenson-Hamilton Knowledge Resource Centre and Museum (Skukuza Museum) in the Kruger National Park, where a total of 164 responses were obtained. Eight hypotheses were formulated and tested by utilizing Spearman’s correlation, investigating visitor expectations, experience, perceived quality, satisfaction, pleasure, confirmation and visitor intent. The results confirm the hypothesis that when tourists’ expectations are met, they experience a positive service experience and perceive the high quality. When tourists derive pleasure and satisfaction from the visit, they usually commit to a follow-up visit. The results of this study provide a basis for museum management, public sector visitor attractions, employees and academia to further develop these museums as successful visitor attractions.
Mismeasurement of the virtual human body: analysing error of landmark acquisition
Authors: Černý Dominik , Urbanová Petra
Published: October 2024

Modern physical anthropology increasingly employs non-invasive methods that use 3D models representing the human body. Frequently, these are 3D models of a person’s physical appearance, i.e., face or body. A traditional approach to analyse these records is to process discrete points (landmarks, feature points) collected manually on the model surface. The digitization of landmarks and associated errors have been sufficiently studied in the context of the human face, due to its functional and aesthetic importance. However, other parts of the human body have not received the same level of attention.
The aim of the present study was to quantify the error of body landmarks when collected in 3D fullbody models and to explore how it relates to other model properties, such as a demographic and somatic indicators.
The study tested two datasets of 10 body landmarks acquired in 60 models (32 males and 28 females). The data acquisition was carried out during the time span of 14 days. The magnitude of the digitization error for each point was acquired and tested between groups defined according to their anatomical location (shoulders, arms, legs; torso and limbs or body side), sex, age, height and body type.
The results of this study showed that the error of digitising landmarks in a 3D model was greater compared to the error reported in the literature when acquiring landmarks on the human body. The digitization error was independent of participants’ age, sex, height, and body type but was correlated with the anatomical location, where the upper chest, neck, and back on the knee yielded the highest digitization errors. In addition, this study showed that landmarks located on the shoulders and arms exhibited an error which was correlated negatively with the volume of the lower and upper half of the body and positively with the body depth.

Authors: . Kamal , Dhaka A.K. , Rana Anjali
Published: October 2024

Oilseeds play a pivotal role in India’s agricultural economy, with oil derived from these crops serving as a fundamental raw material for various industries. Sulphur (S) plays a crucial role in augmenting both the yield and quality of oilseed crops. Achieving a balanced fertilization strategy that incorporates S is imperative for fostering the high-quality growth of oilseed crops. Several researches indicate that S application in the range of 20-60 kg ha-1 substantially influences crop growth, yield, nutrient uptake and the economic aspects of oilseed cultivation. This review offers valuable insights into the latest research endeavors conducted in the realm of oilseed crops, specifically concerning sulphur application.

Background: No published data on two-dimensional echocardiographic quantitation of left ventricular size and function in Indian mongrel dogs is reported till date. Methods: Reference intervals for linear and area measurements of left ventricle size and function was generated in fifty healthy mongrel dogs (25 males, 25 females; mean age=1.59±0.13 yr; mean body weight=16.66±0.73 kg) using two-dimensional echocardiography. Dogs deemed healthy after thorough clinico-physiological, hematological, radiographic, electrocardiographic and echocardiographic evaluation were included in study.Relationship between two-dimensional linear and area measurements of left ventricle and body weight and, between same measurements obtained from different tomographic planes was studied using linear regression analysis. Result: Linear left ventricular measurements, left ventricular internal and external area, mitral valve orifice area showed significant (P less than 0.001) positive correlation with body weight while fractional shortening and ejection fraction showed significant (P less than 0.001) weak negative correlation with body weight. Left ventricular internal length in diastole, interventricular septum thickness and left ventricular internal dimension in systole and left ventricular free wall thickness in diastole were significantly (P less than 0.01) higher in male dogs while mitral valve orifice area was significantly (P less than 0.01) higher in female dogs. All linear measurements of left ventricular size obtained from different tomographic planes displayed significant (P less than 0.001) correlation with each other.

Background: The textile use of llama fiber, achieved through genetic improvement, llama selection and management, shows great potential for producing high-quality clothing and fabrics; providing an alternative income to highland residents who raise llamas. The aim of this research was to determine the fiber medullation of white Ch´aku and Q´ara color varieties of Llamas (Lama glama) from the communities of the Macusani district, Puno Peru. Methods: A total of 88 Llamas from the Ch´aku and Q´ara white color varieties, including males and females, from the age of milk teeth and two teeth, were used. Fiber samples of approximately 10 g were taken from the thigh, middle rib and shoulder, totaling 264 samples. Samples were analyzed at the Fiber Laboratory of the District Municipality of Corani, using the FIBER MED equipment. Data were analyzed in a completely randomized design (CRD) with a 2(variety) × 2 (sex) × 2 (age group) × 3 (body area) factorial arrangement. Result: The percentage of fiber medullation types in Ch´aku and Q´ara Llamas averaged 46.02% and 47.38%, showing no significant difference (p greater than 0.05). In Ch´aku Llamas, a statistical difference was observed by sex (p less than 0.05) for the percentage of medullated, non-medullated and continuous fibers in males and females. In Q´ara variety, there was a significant difference in the percentage of medullated, non-medullated and continuous fibers between milk teeth and two teeth age groups. There was no significant difference (p greater than 0.05) between body area samples.

In addition, the use of the Canva application-based ASSURE model learning design increases the value drastically in the evaluation of Fiqh learning. The ASSURE model learning design in a nutshell is the process of designing a learning model from analyzing the character of students, how to learn, choosing and applying methods, appropriate learning media, and conducting evaluations and revisions during learning. In designing Canva application-based learning, it is necessary to adjust to student interests and the times, so that the learning process is not boring and more interesting.
Ações desenvolvidas com idosos quilombolas de comunidade rural em tempos de pandemia do covid-19: relato de experiência
Authors: Da Silva Josileide Gomes , Oliveira Lúcia Marisy Souza Ribeiro de , Lima Kedma Magalhães
Published: October 2024

Este relato de experiência vem apresentar as vivências com um grupo de idosos durante a pandemia do coronavírus SARS-CoV-2. Trata-se de uma pesquisa do tipo descritivo das ações realizadas no formato de teleatendimento fisioterapêutico em tempos de pandemia, entre junho de 2020 e agosto de 2021. O objetivo do estudo foi descrever as ações extensionistas vivenciadas com idosos quilombolas da zona rural durante a pandemia da covid-19. Com a paralisação de todos os serviços não essenciais pelas medidas restritivas deliberadas por governantes para barrar a contaminação das pessoas, os atendimentos fisioterapêuticos sucederam-se por meio de teleatendimento com uso de aparelhos celulares, ocorrendo em três etapas: reunião online, cinesioterapia recreativa e orientações. A fisioterapia busca, por meio deste novo formato, atuar com comunidades tradicionais, fundo de pastos e quilombolas. O teleatendimento pode ser uma forma de a fisioterapia reinventar sua atuação na população que trabalha na agricultura familiar e que tem pouco acesso aos serviços de saúde.

As redes sociais proporcionam exposição de informações, com potencial para modificar comportamentos. O objetivo deste estudo foi descrever percepções sobre alimentação/nutrição com o uso do Instagram®. Trata-se de um estudo transversal, com amostra por conveniência, constituída por mulheres de 20 a < 60 anos. Foram investigadas variáveis sociodemográficas, hábitos alimentares relacionados com a rede social e antropometria. Os principais resultados foram: 23% das participantes alegaram seguir perfis sobre nutrição/alimentação todo dia, 25,7% toda semana e 32,7% de 2-3 vezes/mês; 89,4% declararam que a leitura desses conteúdos já motivou a realização de mudanças na alimentação (sempre e/ou de vez em quando), sendo o objetivo com maior percentual de respostas a saúde/qualidade de vida (44,2%); entretanto, o percentual que sempre busca conferir a veracidade das informações restringiu-se a 18,6%; 61,9% relataram que receitas influenciaram esporadicamente o preparo de refeições e 49,5% realizam as refeições sempre com distrações. Conclui-se que o Instagram® representa importante ferramenta para a disseminação de conteúdos sobre nutrição, com devida atenção para a veracidade das informações.
