WHAT ARE EDTECHS? A SYSTEMATIC LITERATURE REVIEW
Authors: Lopes Yan Miguel , Silva e Meirelles Dimária
Published: September 2024

ABSTRACT In contrast to the recurring drop of demand in traditional education institutions, it is noticed a rapid expansion of Edtechs. Considered as educational startups with alternative learning models and innovative methodologies based on multidisciplinary collaboration, we do not know much from a theoretical point of view about their specific characteristics, which contrasts with traditional teaching modalities. This article aims to evaluate the literature about Edtechs, assessing both the adopted concept and the challenges and trends regarding the future of these new educational institutions. The methodology used was a literature review divided into two stages. The first stage was quantitative, focusing on the volume of publications by author, journal, and other descriptive information. The second stage was qualitative, focusing on the content of the published articles. The quantitative analysis allowed us to conclude that studies on the topic are recent and have a growing publication trend, but there is no publication concentration in journals. The qualitative analysis concluded that Edtechs have a social mission to mobilize new technologies to transform and improve the reach and quality of education and student's life and career prospects. This research is relevant for the academic and corporate community interested in the topic, as it consolidates all the scientific knowledge about Edtechs.

ABSTRACT Regions with semi-arid climates have environmental conditions that result in abiotic stress to plants. The largest melon (Cucumis melo L.) production area in Brazil, the state of Rio Grande do Norte, has these climatic characteristics. Use of biostimulants in these production systems can mitigate effects of abiotic stress and increase yield and fruit quality. The objective in this study was to evaluate the physiological and production characteristics of melon, under the application of biostimulants. The biostimulants Acadian®, Folicist® and Nov@® were applied and compared to the control treatment (no biostimulants), in ‘Goldex’ and ‘McLaren’ melons. Nov@® led to higher CO2 assimilation, transpiration and stomatal conductance, as well as ascorbate peroxidase, in ‘Goldex’ and ‘McLaren’. Greater catalase was obtained with the application of Nov@®, while the use of Folicist® resulted in higher malondialdehyde content. The cultivar ‘McLaren’ exhibited the best physiological and biochemical performance, and ‘Goldex’ the best yield. Folicist® promotes physiological adaptations to stress without impairing photosynthetic activity. The biostimulants increased yield and number of fruits per plant and promoted physiological adaptations to semi-arid conditions.

ABSTRACT The thermal modification of wood is a process that alters its chemical composition, aiming to improve technological properties such as dimensional stability, reduction of equilibrium moisture content, homogeneity, or color. In this context, this study aimed to evaluate the colorimetry and chemical properties of the wood of Parkia pendula (angelim-saia) and Simarouba amara (marupá) that was thermally modified by different methods. Three treatments were evaluated: T1 (pre-treatment in an oven for one hour at 120 °C and treatment in an oven at 180 °C for three hours); T2 (pre-treatment in an autoclave at 125 °C for three hours under 1.2 kgf cm-2 and treatment in an oven at 180 °C for three hours); and T3 (without pre-treatment, with sample treatment in vegetable oil). The thermally modified wood was evaluated in relation to untreated wood for structural chemical composition (extractives, lignin, holocellulose and ash content), colorimetric parameters defined through the CIELAB (Commission Internationale de l´Eclairage) system and total color variation. We detected a significant increase in extractives content and a decrease in holocellulose and lignin content in T3 for both species, which can be explained by the impregnation of oil in the wood samples. The thermal modification caused the surface darkening of the wood of both species, which was more pronounced in P. pendula. Despite the colorimetric change, there was no chemical damage to the wood.

Published: September 2024

Abstract Salmonella spp. is one of the leading causes of gastroenteritis worldwide. Salmonella Heidelberg is an emergent pathogen associated with multidrug-resistant outbreaks linked to poultry products. Their high persistence in the environment may be associated with their ability to adhere to different surfaces and form biofilms. Owing to increased antimicrobial resistance worldwide, researchers have investigated the use of lactic acid bacteria (LAB) as a biological control against pathogenic microorganisms. This study aimed to evaluate the ability of LAB to control the formation of S. Heidelberg biofilms on polystyrene surfaces. The antibiofilm activity of nine LAB strains, all belonging to Lactobacillus genera, related to the inhibition of biofilms produced by S. Heidelberg was evaluated in vitro. All treatments, except LAB1 (Lactobacillus salivaris), showed antibiofilm activity. However, LAB did not reduce bacterial counts. Our results show that LAB can avoid or delay biofilm formation by S. Heidelberg on polystyrene surfaces and may be used for in vivo studies as a potential alternative to help control this pathogen in food industries.

Resumo Salmonella spp. é uma das principais causas de gastroenterite em todo o mundo. Salmonella Heidelberg é um patógeno emergente associado com surtos com multirresistência antimicrobiana vinculados aos produtos avícolas. A sua alta persistência no ambiente pode estar associada com sua habilidade de aderir a diferentes superfícies e formar biofilmes. Devido ao aumento da resistência antimicrobiana em todo o mundo, os pesquisadores têm investigado o uso de bactérias acido láticas (BAL) como um controle biológico e de microrganismos patogênicos. O objetivo deste estudo foi avaliar a habilidade de BAL no controle de biofilmes produzidos por S. Heidelberg em placas de poliestireno. Foi avaliada a atividade antimicrobiana in vitro de nove BAL, todas pertencentes ao gênero Lactobacillus, na inibição e na remoção de biofilmes produzidos por S. Heidelberg. A formação de biofilme só ocorreu quando a BAL1 (Lactobacillus salivaris) foi utilizada. Todos os outros tratamentos demonstraram atividade antimicrobiana. Entretanto, a BAL não foi capaz de reduzir a contagem bacteriana. Os resultados obtidos demonstram que BAL são capazes de prevenir ou retardar a formação de biofilme por S. Heidelberg em superfícies de poliestireno e podem ser utilizadas em estudos in vivo para determinar o seu potencial alternativo no controle deste patógeno na indústria de alimentos.

Abstract This study aimed to evaluate the effects of mineral sources and rosemary oil levels in the diet of commercial layers on the qualitative and quantitative characteristics of the waste generated. Manure was obtained from 288 commercial laying hens of the HyLine Brown lineage (semi-heavy layers) at 30 weeks of age over a period of 112 d (four cycles of 28 d). A completely randomized design was used with a 2×3 factorial scheme with repeated measures over time (16 repetitions), with two mineral sources (inorganic and organic) and three levels of rosemary oil (0, 100, and 200 mg kg-1). The waste was collected weekly, weighed, and the calculations of waste production, residue coefficient (RC) were performed. Also analyses of total solids (TS), volatile solids (VS), pH, macro-, and micro-minerals were performed. Mineral sources affect the quality characteristics of the manure. The amount of rosemary oil affected the quantitative and qualitative characteristics of the waste generated. It was concluded that diets containing organic minerals resulted in waste with less polluting power, as it had a lower TS, pH, total N, and total P values. Rosemary oil increased manure production in natural matter (NM) and increased the TS and VS values in the manure layer, causing a greater environmental impact.

Abstract The aim of this study was to characterize the production and anaerobic digestion of manure from finishing pigs subjected to feed restriction or supplemented with ractopamine or chromium (Cr). The waste came from 50 barrows in the finishing phase, aged ± 154 days, with a starting weight of 99.0 ± 4.4 kg and a final weight of 117.2 ± 5.8 kg. The experimental diets were as follows: control (conventional diet), qualitative restriction (7.5% reduction in net energy compared to the control diet), quantitative restriction (15% reduction in feed supply), Cr (0.8 mg), and ractopamine (10 ppm). The data were subjected to an analysis of variance using a randomized block design, in which the weeks of analysis were considered blocks (cofactors). There were no differences in manure production between the diets regarding natural matter (NM), dry matter (DM), mineral matter (MM), or organic matter (OM). Animals fed the control diet had the highest residue coefficient, and there was no difference among the other diets. No differences were observed among the diets regarding total solids, pH, or total nitrogen in the tributaries or effluents. The highest biogas yield (574 mL g-1) of added volatile solids (VS) was obtained in the digesters supplied with manure from animals fed a qualitatively restricted diet. It can be concluded that a qualitatively restricted diet results in higher manure production but with lower nitrogen and phosphorus excretion and higher biogas yields.

Abstract Calcareous seaweed (Lithothamnium calcareum) is a source of organic minerals and has been used as an alternative food in poultry nutrition. The objective is to evaluate the levels of calcareous algae in the diet of chickens during the rearing and pre-laying phases, as also on the performance and thermoregulation variables. One hundred and forty-four semi-heavy Hisex Brown hens, aged 12 to 18 weeks, were used in the rearing and pre-laying stages. They were fed with four levels of calcareous algae (0%, 10%, 20%, 30%), which were used in place of the calcitic limestone. Six replications and six birds were used per experimental unit, distributed in a completely randomized design. Feed intake, weight gain, feed conversion, body weight, viability, and thermoregulation through cloacal temperature (°C), mean body temperature (°C), and mean skin temperature (°C) were evaluated. There was no significant difference (P > 0.05) in the thermoregulation of the birds. There was a difference (P < 0.05) in the feed intake during the pre-laying phase, however, the other parameters showed no difference (P > 0.05). The inclusion of up to 30% calcareous algae in the diet of semi-heavy laying hens in the rearing and pre-laying phases did not affect the performance or thermoregulation of the birds. Therefore, it is possible to substitute calcitic limestone with up to 30% of the calcareous algae in the diet of semi-heavy laying hens.

Resumo A alga calcária (Lithothamnium calcareum) é fonte de minerais orgânicos e tem sido utilizada como alimento alternativo na nutrição de aves. O objetivo foi avaliar níveis de alga calcária na dieta de poedeiras semipesadas nas fases de recria e pré-postura sobre variáveis de desempenho e termorregulação. Foram utilizadas 144 galinhas semipesadas da linhagem Hisex Brown, com idade entre 12 a 18 semanas, nas fases de recria e pré-postura, alimentadas com 4 níveis de alga calcária (0%, 10%, 20%, 30%) em substituição ao calcário calcítico, seis repetições e seis aves por unidade experimental, distribuídas em delineamento inteiramente casualizado. Foram avaliados consumo de ração, ganho de peso, conversão alimentar, peso corporal e viabilidade, termorregulação através da temperatura cloacal (°C), temperatura corporal média (°C) e temperatura média da pele (°C). Não houve diferença significativa (P>0,05) na termorregulação das aves. Houve diferença (P<0,05) para o consumo de ração na fase de pré-postura, os demais parâmetros não apresentaram diferença (P>0,05). A inclusão de até 30% de alga calcária na dieta de poedeiras semipesadas nas fases de recria e pré-postura não afetou o desempenho e a termorregulação das aves. Portanto, é possível substituir até 30% de alga calcária por calcário calcítico na dieta de poedeiras semipesadas.

Abstract The aim of this study was to evaluate the effect of substituting virginiamycin with yeastbased products in high-energy diets containing monensin on the nutrient digestibility and ruminal parameters of cattle. Five crossbred Nellore × Holstein steers (initial body weight 281 kg ± 9.2 kg) were allotted to a 5 × 5 Latin square design. The diets were composed in dry matter basis of corn silage (355 g kg-1), and concentrate composed of ground corn, soybean meal, soybean hulls,mineral mix, limestone, salt and urea (645 g kg-1). The treatments were: 1 - control, 18 mg kg-1 dry matter (DM) virginiamycin (VM); 2 - enriched yeast culture (Saccharomyces cerevisiae) at 7 g animal day-1 (EYC 7); 3 - enriched yeast culture (S. cerevisiae) at 14 g animal day-1 (EYC 14); 4 - autolyzed yeast (S. cerevisiae) at 7 g animal day-1 (AY 7); and 5 - autolyzed yeast (S. cerevisiae) at 14 g animal day-1 (AY 14). Monensin (18 mg kg-1 DM) was added to the mineral mix in all treatments. No significant differences (P > 0.05) were found for DM intake (mean 8.36 kg DM), organic matter (OM) digestibility (average of 58.39%), or mean ruminal pH (mean 6.75) among treatments. Moreover, the treatment did not have a significant effect on the short-chain fatty acid or ammonia nitrogen concentrations. These results indicated the possibility of replacing virginiamycin with yeast-based products at the lowest level (7 g of enriched yeast culture or autolyzed yeast per animal day-1) in high-energy diets containing monensin.

Abstract This study aims to determine and compare the metabolizable energy values and metabolizability coefficients of three types of corn oil (crude, semi-refined, and acid) for broiler chickens. 240 Cobb500™ chickens were randomly allocated into metabolic cages, resulting in four treatments, ten replicates, and six birds per experimental unit. The birds fed on diets specific to each treatment. Total excreta was collected from the day 23rd to the 27th. Gross energy (GE), apparent metabolizable energy (AME), and nitrogen-corrected apparent metabolizable energy (AMEn) were calculated for each oil type. The metabolizability coefficient values of ether extracts (MCEE) were also determined. Statistical analysis was performed using Tukey test at a 5% probability. There was a significant difference in AME and MCEE values (P<0.05). Crude corn oil showed higher AME and MCEE values than acid corn oil. The findings are crude corn oil - GE: 9,330 kcal/kg, AME: 8,916.84 kcal/kg, AMEn: 8,905.60 kcal/kg, MCEE: 97.14%; semi-refined corn oil - GE: 9,480 kcal/kg, AME: 8,547.99 kcal/kg, AMEn: 8,303.46 kcal/kg, MCEE: 96.64%; acid corn oil - GE: 9,114 kcal/kg, AME: 7,197.73 kcal/kg, AMEn: 7,515.68 kcal/kg, MCEE: 96.17%.

Published: September 2024

Abstract This study aimed to verify the influence of wave size on the performance of surfers in the main division of the World Surf League (WSL) Tour. The study included 31 surfers from the top division of the 2019 tour of the WSL. The two best waves of each surfer per heat were evaluated, separated, and combined, from round one to the final, totaling 1749 waves and 847 combinations. The study variables were related or associated with the number of victories and ranking. Spearman's correlation coefficient was used in all correlations in the study and Binary Logistic Regression to verify possible associations and estimate the odds ratio (OR) between the variable wave size and the result. Through the evidence, it was concluded that: 1) those surfers who during the season caught the biggest waves of the heats more often were more likely to win their heats and achieve better rankings in the season; 2) all surfers had to catch a portion of just no bigger waves and the best classifieds took advantage of them better; 3) the biggest waves had the greatest influence on the tubes, then on the turning maneuvers and lastly on the aerials; 4) the three groups of maneuvers were decisive for the good performance in the season, being the tubes the most decisive.

Authors: Mundim Gabriela Duarte Almeida , Pires Maria Raquel Gomes Maia , Torres Maria Verônica Sousa , Silveira Aline Oliveira
Published: September 2024

ABSTRACT Objective: To map evidence about care and gender stereotypes in nursing scientific research. Method: A scoping review developed under the JBI framework with analysis of gender perspective in care approaches. The searches were carried out on January 31, 2023 in SciELO, Scopus, CINAHL, PubMed, BDENF. Results: Of the 3,743 studies located, 25 were included. Evidence was grouped into categories: essentially female care (n = 9; 36%); calling and service of love (n = 3; 12%); erasure of gender inequalities (n = 2; 8%); “inadequate and harmful” care (n = 5; 20%); neutralization of gender and bodies (n = 3; 12%); and reporting oppression in care work (n = 3; 12%). Conclusion: Most scientific research on care reproduces gender stereotypes that reinforce the oppression of women in nursing. In contrast, resistance denounces naturalization of care as “inadequate and harmful”, for perpetuating gender oppression in care work.

ABSTRACT There is presently no disease-modifying therapy for Alzheimer’s Disease (AD), which is the most prevalent cause of dementia. Objective: This study aspires to estimate the efficacy and safety of cell-based treatments in AD. Methods: Observing the Joanna Briggs Institute (JBI) methods and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, a systematic search was accomplished in PubMed, Medical Literature Analysis and Retrieval System Online (Medline, via Ovid), Embase; Cochrane, and Cumulative Index of Nursing and Allied Health Literature — CINAHL (via EBSCO) databases up to June 2023. The relevant clinical studies in which cell-based therapies were utilized to manage AD were included. The risk of bias was evaluated using the JBI checklists, based on the study designs. Results: Out of 1,014 screened records, a total of five studies with 70 individuals (including 59 patients receiving stem cells and 11 placebo controls) were included. In all these studies, despite the discrepancy in the origin of stem cells, cell density, and transplant site, safety goals were obtained. The intracerebroventricular injection of adipose-derived stromal vascular fraction (ADSVF) and umbilical cord-derived mesenchymal stem cells (UC-MSCs), the intravenous injection of Lomecel-B, and the bilateral hippocampi and right precuneus injection of UC-MSCs are not linked to any significant safety concerns, according to the five included studies. Studies also revealed improvements in biomarkers and clinical outcomes as a secondary outcome. Three studies had no control groups and there are concerns regarding the similarity of the groups in others. Also, there is considerable risk of bias regarding the outcome assessment scales. Conclusion: Cell-based therapies are well tolerated by AD patients, which emphasizes the need for further, carefully planned randomized studies to reach evidence-based clinical recommendations in this respect.
Ato de magia: a questão da naturalização na obra de Abdelmalek Sayad
Authors: Braga Mariana Moron Saes , Braga Antonio Mendes da Costa
Published: September 2024

Resumo Do ponto de vista jurídico, a naturalização é um modo secundário de se obter a nacionalidade de um Estado, resultante da manifestação de vontade. Mas é possível tratar a questão da naturalização apenas como uma questão jurídica e como uma manifestação de vontade individual? Este artigo procura responder esta indagação dialogando com as contribuições de Abdelmalek Sayad, desenvolvendo dois argumentos: (1) para Sayad a naturalização não deve ser encarada como uma simples operação administrativa, que como num ato de magia transforma, por exemplo, um argelino em um francês, através duma publicação no diário oficial. Para Sayad a naturalização envolve muito mais do que apenas sua dimensão jurídica; (2) a questão da naturalização em Sayad deve ser compreendida dentro de sua crítica ao mundo pós-colonial, hegemonicamente organizado em Estados-nação. Mundo onde migrantes internacionais estão entre aqueles que, por excelência, vivenciam e revelam os paradoxos - as contradições, incoerências do mundo contemporâneo.
Una banda sonora para el respeto: drill, estigma y trayectorias sociales de los hijos de inmigrantes
Authors: Pedreño Cánovas Andrés , Cutillas Fernández Isabel , Sánchez-García Miguel Ángel
Published: September 2024

Resumen Este artículo analiza la relación entre el drill como género musical y el protagonismo que tienen en él las franjas más desafiliadas de los jóvenes de origen inmigrante. Nos servimos de las herramientas teóricas de Abdelmalek Sayad para pensar: de un lado, el estrechamiento de las posibilidades vitales de los hijos e hijas de la migración; y de otro, entender el drill como una estrategia subversiva contra los procesos de estigmatización que experimentan los jóvenes de origen migrante que residen en barrios segregados. Para ello analizamos la propuesta musical de Key 21, uno de los mayores exponentes del drill, residente en una zona de trabajadores jornaleros de la agricultura intensiva en el sur de España. El análisis de las canciones de Key 21 muestra las estrategias de los jóvenes hijos de la migración para transformar el estigma en emblema de la propia identidad y de la identidad de sus barrios.
Las experiencias de trabajo en la confección de indumentaria vistas desde los aportes de Sayad
Authors: Delmonte Allasia Antonella
Published: September 2024

Resumen Acercarnos a la costura resulta fundamental para conocer las experiencias de vida migrante en tanto la industria de confección se constituye desde hace décadas como uno de los principales nichos laborales disponibles en Buenos Aires para migrantes. En este artículo analizo en profundidad cómo impacta la condición migratoria en las experiencias y relaciones de trabajo en la confección de indumentaria en base a datos cualitativos. Con este fin, incorporo un apoyo sustantivo en las categorías elaboradas por Abdelmalek Sayad desde una lectura situada. Sus ideas sirven a modo de prisma para mirar la especificidad migrante en una fábrica de confección de prendas de vestir y -con la intención de evitar la importación de categorías analíticas de forma lineal y abstracta- ellas se conjugan con las conclusiones de un conjunto de investigadores/as locales que permiten dar un sentido situado espacial y temporalmente a las experiencias obreras observadas.

Published: September 2024

Resumo Esta pesquisa tem como objetivo identificar como o tema das drogas aparece na produção intelectual do Serviço Social registrada na Revista Serviço Social e Sociedade dos anos de 1979 a 2022. Trata-se de pesquisa exploratória, qualitativa cunhada a partir do método materialista histórico-dialético. Os artigos elegíveis para a análise foram levantados por palavras-chave, tendo também como critério de inclusão a publicação por assistentes sociais. Dos 1.279 escritos da Revista Serviço Social e Sociedade pesquisados, apenas quatro artigos abordam a questão das drogas como tema central, incluindo o termo ou termos correlatos em seus títulos. Apesar de notarmos um pequeno número de artigos publicados sobre o tema percebe-se a presença de publicações que incorporam a crítica da economia política para a reflexão acerca da temática diferindo-se de pesquisas baseadas em casos e focadas em análises conservadoras e/ou superficiais.
Como morreu Althusser? Ensaio sobre marxismo e Serviço Social
Authors: Cordeiro Michael Gonçalves
Published: September 2024

Resumo Este artigo objetiva revisitar o processo de crítica às ideias do marxista francês Louis Althusser no âmbito da história do Serviço Social brasileiro, centrando-se na construção da história dos fundamentos teórico-metodológicos da profissão. O recorte metodológico foram as literaturas das décadas de 1980 e 1990 que se tornaram mais influentes nas décadas seguintes na formação teórico-metodológica profissional, das quais coincidem com o período central de crítica das ideias althusserianas no Serviço Social e afirmação do que posteriormente se consolidou como discurso oficial acerca do seu pensamento. Os principais resultados apontam para uma aproximação enviesada das ideias de Althusser e para uma ausência de crítica direta e sistemática ao seu pensamento no âmbito do Serviço So cial brasileiro.

Resumo Introdução: O objetivo deste estudo foi investigar o papel do fenofibrato, um agonista do receptor ativado por proliferadores de peroxissoma-α, na lesão renal induzida por obesidade (lipotoxicidade) em camundongos submetidos à uninefrectomia. Métodos: Camundongos C57BL/6 foram submetidos a uninefrectomia e cirurgias simuladas (sham) e alimentados com dietas normocalóricas ou rica em gordura. Após 10 semanas, os camundongos obesos receberam fenofibrato a 0,02% por 10 semanas. Avaliamos função e morfologia renal, bem como níveis de mediadores inflamatórios e fibróticos e marcadores do metabolismo lipídico. Resultados: Camundongos alimentados com dieta rica em gordura desenvolveram obesidade e hiperlipidemia características, com subsequente acúmulo de lipídios e danos renais, incluindo expansão mesangial, fibrose intersticial, inflamação e proteinúria. Essas alterações foram maiores em camundongos obesos uninefrectomizados do que em camundongos obesos sham. O tratamento com fenofibrato preveniu hiperlipidemia e lesões glomerulares, reduziu o acúmulo de lipídios, melhorou a disfunção renal e atenuou a inflamação e fibrose renal. Além disso, o tratamento com fenofibrato reduziu a expressão no tecido renal do inibidor do ativador do plasminogênio-1, da proteína quimiotática de monócitos-1 e a expressão local do fator de crescimento de fibroblastos-21. Conclusão: A ativação do receptor ativado por proliferadores de peroxissoma-α pelo fenofibrato, com subsequente lipólise, atenuou lesões glomerulares e tubulointersticiais induzidas por lipotoxicidade renal, protegendo, assim, os rins de camundongos uninefrectomizados contra lesões induzidas por obesidade. Os achados do estudo sugerem uma via na ação farmacológica do fenofibrato, fornecendo insights sobre os mecanismos envolvidos no dano renal causado pela obesidade em doadores renais.

Abstract Introduction Low-intensity resistance training combined with blood flow restriction has shown to be effective in musculoskeletal rehabilitation. The appropriate arterial occlusion pressure (AOP) to induce partial blood flow restriction has been suggested through regression equations. Objective This study sough to investigate whether limb fat-free mass and fat mass can be used as predictors of AOP in the upper limbs in young adults. Methods Vascular Doppler ultrasound was performed in the proximal right arm of 49 healthy individuals of both sexes (aged 18-30 years) to determine AOP in the brachial artery. Segmental fat mass and fat-free mass were estimated by multifrequency bioelectrical impedance. The best fit model to predict AOP was tested by including the independent variables one by one in a hierarchical regression analysis. Results Systolic blood pressure (SBP) alone explained 54.6% of the variation in AOP. Included in different models in combination with SBP, arm circumference (8.1%), body mass index (7.9%), and arm fat-free mass (7.1%) composed similar models in terms of goodness of fit. Arm fat mass (1.7%), in turn, did not add predictive strength to the model. Conclusion SBP and arm circumference may be used to estimate the cuff pressure to induce blood flow restriction in blood flow restriction therapy.

Abstract The study conducted a review of the parasitological profile of vegetables from 2001 to 2021, considering the type, consumption, and cultivation, globally. The databases searched included MEDLINE, SciELO, Web of Science, Science Direct, and Scopus using the terms "Detection OR Prevalence OR Incidence OR occurrence OR contamination AND vegetable OR fruit AND Helminth OR egg OR Parasite OR cysts OR protozoa". A total of 16,600 articles were found, 117 of which were reviewed. Of the 391,291 samples, 3.85% (15,095) were contaminated by parasites. Among those positive, 30.10% (4,543/15,095) contained enteroparasites commonly of human origin and 58.78% (8,873/15,095) came from markets. Few articles mentioned the cultivation type, but among those, conventional cultivation showed more contamination (42.34%; 224/529). Herbaceous vegetables were the most contaminated (56.84%; 8,580/15,095. Ascaris lumbricoides was found in 10.16% (1,535/15,095) of the samples. Lettuce was the most contaminated (20.43%; 3,084/15,095).

Abstract Trichinellosis is a zoonotic disease that has been studied mainly in domestic pigs (Sus scrofa domesticus). The cycle involves infection in domestic and wild fauna, which fulfill complex ecological roles, where Trichinella spiralis is reported in wild boar (Sus scrofa). The objective of this study was to determine the prevalence of trichinellosis in wild boar and evaluate the distance of positive animals to the nearest urbanization areas in Argentina Patagonia. Necropsies were carried out on wild boar hunted in the Nahuel Huapi and Lanín National Parks and surrounding areas. Skeletal muscle samples were collected from 1,694 wild boar and artificial digestion was performed on all samples. Trichinella spp. were found in 96 (5.8%) wild boar (0.2 to 424 Larvae/g). Parasitism in wild boar depends on the distribution of the population in natural and urban areas. Infected wild boar were found near peri-urban areas, demonstrating the importance of routine epidemiological surveillance and sanitary measures in and around cities. More research is needed to identify the Trichinella species that infect wild animals. We recommend the application of active and passive epidemiological surveillance in South America on exotic and native fauna that are hunted and consumed by humans.

Recent developments in supercapacitor devices have prompted an increasing demand for energy storage devices that operate at a micro-scale. Fabrication of such devices requires environmentally benign, compatible materials derived from waste-food industries. Therefore, this study aims to develop a carbon functional self-dual-doped from waste-food industries of mangosteen peel sources to optimize volumetric level supercapacitor. A simple integrated pyrolysis with ZnCl2 assistance was applied to synthesize the self-dual-doped porous carbon. The precursor was designed as a thin-tubelike additive-free form at a constant density of 1.21 g cm-3. The optimized material (CNR-OZn-5) exhibited a unique morphology from a combination of short nanofibers and a unique reef-like architecture. Furthermore, it had a surface area of 670.569 m2 g-1 with O (6.00%) and Zn (0.31%) doped. In the two-configuration system, the measuring electrodes yielded capacitive properties of 261 F g-1 and 315.81 F cm-3 at 1 A g-1. At 10 A g-1, the coulombic efficiency and rate capability were 98% and 67.56% with an enhanced pseudo-capacitance contribution of 20.9% and low resistance of 0.05 Ω. The specific energy in the symmetrical supercapacitors system was 13.14 and 16.17 Wh L-1 in 1 M H2SO4 electrolyte. This new strategy, coupled with the use of waste-food-derived self-dual-doped carbon materials, holds significant potential for achieving high-level volumetric characteristics in sustainable energy storage system.
Effects of exposure sequence and GGBS cement replacement on performance of concrete subjected to carbonation and chloride ingress

In a variety of applications, such as in tidal zones, abutments of bridges and concrete tunnel linings, reinforced concrete is exposed to both carbonation and chloride ingress. The exposure can be either simultaneous or sequential. However, durability design rarely considers synergistic effects due to carbonation and chloride ingress, even though this may have detrimental consequences for performance. Comparative implications of exposure sequence across different concrete compositions are also unknown. In this study, an experimental investigation on the effects of the sequence of carbonation and chloride ingress was conducted, using two concretes which differ by 50% cement replacement with ground granulated blast furnace slag (GGBS). Specimens were exposed to a combination of 10% CO2 accelerated carbonation and immersion in 3% sodium chloride solution, in either sequence, and compared with companion samples subjected to only one of these aggressive environments. The extent of carbonation was measured using phenolphthalein indicator solution, while silver nitrate and Rapid Chloride Testing provided indicators of the chloride ingress. For both concrete mixes, specimens with prior chloride ingress exhibited a decreased rate of carbonation when compared to specimens with no prior exposure. Conversely, specimens with prior carbonation displayed an increased rate of chloride ingress compared to non-carbonated counterparts and a step in the acid soluble chloride content in the region of the carbonation front. The concrete composition appeared to play a role since a greater increase in chloride diffusion coefficient due to prior carbonation was observed in the mix with 50% GGBS replacement than the mix without. These findings suggest that in concrete structures exposed to air and saline environments, the effects of sequential exposure should be characterised.
Optimal content of bio-fibers in structural ice
Authors: Fantilli Alessandro P. , Frigo Barbara , Dehkordi Farmehr M.
Published: September 2024

The use of ice as structural material has two main concerns: the low strength and the brittle failure of the structures. With the aim of finding a solution to these problems, an experimental campaign, performed on fiber-reinforced ice (FRI) samples, made with plain water and bio-fibers, is presented in this paper. In total, 12 ice prisms were cast at − 18 °C with a different content of fibers, and then tested in three-point bending and uniaxial compression. Test results indicate that the presence of a reinforcement increases both flexural and compressive strength with respect to plain ice. Moreover, FRI is a tougher material, as multiple cracking and deflection hardening behavior can be observed in the flexural tests. However, the mechanical performances of plain ice are not always enhanced by the fiber-reinforcement. Therefore, an empirical model, capable of predicting the optimal content of bio-fibers, is also proposed.
