ABSTRACT Copper is an essential element for beet; however, it needs to be made available in adequate quantities since this nutrient, which is a heavy metal, can cause toxicity to plants and/or humans. This study aimed to evaluate the agronomic performance of beet fertigated with copper in a semi-arid region of Brazil. Two experiments were carried out in complete randomized blocks, with five treatments (0, 1.5, 3.0, 4.0, and 6.0 kg ha-1 of copper) and four replicates. In 2019, the copper content was within the adequate range for beet. In 2021, fertigation with copper above 0.8 kg ha-1 led to contents in the phytotoxicity range, which may explain the reduction in total and tuberous root dry mass accumulation. Fertilization with copper increased marketable yield in 2019 (17.32 t ha-1 at the dose of 3.9 kg ha-1 of copper), while, in 2021, there was no fit of the equations. Copper fertilization altered the tuberous root pH but did not influence the other tuberous root quality components. Plants fertilized with copper accumulated more copper in the leaves than in the tuberous root, with a maximum accumulation of 6.0 kg ha-1 of copper in 2019 and 2021. Fertilization with 3.9 kg ha-1 suits soils with low copper content.

RESUMO O cobre é um elemento essencial à beterraba, no entanto, é necessário disponibilizá-lo em quantidade adequada uma vez que esse nutriente, que é um metal pesado, pode causar toxicidade às plantas e, ou, ao ser humano. Esta pesquisa teve como objetivo avaliar o desempenho agronômico de beterraba fertirrigada com cobre em uma região semiárida do Brasil. Foram conduzidos dois experimentos em delineados em blocos casualizados ao acaso, com cinco tratamentos (0, 1.5, 3.0, 4.5 e 6.0 kg ha-1 de cobre) e quatro repetições. Em 2019, o teor de cobre estava dentro da faixa adequada para a beterraba. Em 2021, a fertirrigação com cobre acima de 0.8 kg ha-1 proporcionou teores na faixa de fitotoxicidade, o que pode explicar a redução no acúmulo de massa seca total e de raízes tuberosas. A adubação com cobre aumentou a produtividade comercial em 2019 (17.32 t ha-1 na dose de 3.9 kg ha-1 de cobre) enquanto que, em 2021, não houve modelo ajustado. A adubação alterou o pH da raiz tuberosa, mas não influenciou nos demais atributos de qualidade pós-colheita da raiz tuberosa. Plantas adubadas com cobre acumularam mais cobre nas folhas do que na raiz tuberosa, com máxima acumulada em 2019 e em 2021, na dose 6.0 kg ha-1 de cobre. A adubação com 3.9 kg ha-1 é adequada para solos com baixo teor de cobre.

ABSTRACT The collapse of the Fundão Dam in Mariana, MG, in 2015 introduced the challenge of using Technosol, a soil type formed by deposition of iron mining waste along the Doce River banks, for agricultural purposes. This study aimed to determine the optimal water depth for enhancing production of tropical forage, Megathyrsus maximus cv. Mombasa, when grown on iron ore tailings. Additionally, it sought to establish a crop coefficient applicable to the edaphoclimatic conditions of Viçosa, MG, Brazil. The experiment was conducted throughout the summer, fall, and winter of 2022, employing 21 drainage lysimeters. A completely randomized experimental design was adopted, featuring six treatment groups (plants in Technosol receiving water depths ranging from 20 to 120% of the crop’s evapotranspiration, as derived from the control treatment), along with a control group (plants in Latosol with a depth of 100%), each with three repetitions. Our findings showed that irrigation must replace 40% of the crop evapotranspiration. Moreover, cultivating in Technosol resulted in a reduction of productive capacity by 37.39% during the summer/fall and fall seasons. For Mombasa grass grown in Oxisol, crop coefficients of 1.2 during the summer and 1.5 during the fall and winter are advised.

RESUMO O rompimento da Barragem do Fundão em Mariana, MG, ocorrida em 2015, trouxe o desafio de usar o Tecnossolo (tipo de solo) formado pela deposição do rejeito de mineração de ferro nas margens do Rio Doce para agricultura. O objetivo desta pesquisa foi obter a lâmina de água para otimizar a produção da forragem tropical Megathyrsus maximum cv. Mombaça, cultivada em rejeito de mineração de ferro e determinar seu coeficiente de cultura para as condições edafoclimáticas de Viçosa, MG. O experimento foi realizado durante as estações de verão, outono e inverno do ano de 2022, com a utilização de 21 lisímetros de drenagem. O experimento foi distribuído em delineamento inteiramente casualizado com 6 tratamentos (plantas em Tecnossolo com lâminas variando de 20 a 120% da evapotranspiração da cultura, obtida do tratamento-testemunha) e adição de uma testemunha (plantas em Latossolo com lâmina de 100%) com três repetições. Recomenda-se irrigação com reposição de 40% da evapotranspiração da cultura. O cultivo em Tecnossolo diminuiu a capacidade produtiva em 37,39% nos ciclos das estações do verão/outono e outono. Recomenda-se os coeficientes de cultura de 1,2 no verão e 1,5 no outono e no inverno, para o capim-Mombaça cultivado em um Latossolo.

ABSTRACT The consumption of potassium (K) fertilizers in Brazilian agriculture exceeds the national production of this input by more than ten times, indicating the need for alternatives to reduce imports of these products. The objective of this study was to evaluate the performance of the remineralizing rocks phonolite and olivine melilitite as sources of K and other nutrients, as well as the effects of inoculation with Bacillus subtilis and Bacillus megaterium on the solubilization of these rocks in the soil. A greenhouse experiment was conducted using a randomized block design, with four replications, in a factorial arrangement consisting of three K sources (potassium chloride, phonolite, and olivine melilitite), three rates (150, 300, and 600 kg ha-1 K2O), with and without inoculant, and two controls without K (one with and one without inoculant). The experimental units consisted of pots containing 3 kg of soil and a strawberry plant grown for eight months. The treatment with olivine melilitite inoculated with rhizobacteria favored phosphate solubilization when applied the highest rate. Olivine melilitite remineralizer, alone or inoculated with rhizobacteria, increased K+ and Ca2+ contents in the soil when applied at the intermediate and highest rates (300 and 600 kg ha-1 K2O), highlighting this remineralizer as an alternative potassium source for plants.

RESUMO O consumo de fertilizante potássico pela agricultura brasileira supera em mais de dez vezes a produção nacional desse insumo, fato que indica a necessidade de alternativas para diminuir a dependência de sua importação. Diante disso, o objetivo deste trabalho foi avaliar o desempenho dos remineralizadores fonolito e olivina melilitito, como fonte de potássio e outros nutrientes, bem como o efeito da inoculação dessas rochas com as rizobactérias Bacillus subtilis e Bacillus megaterium, no incremento da solubilização destes materiais. O experimento foi realizado em casa de vegetação, sendo conduzido em delineamento blocos casualizados em arranjo fatorial, sendo três fontes (cloreto de potássio, fonolito e olivina melilitito), três doses (150, 300 e 600 kg ha-1 de K2O) com a presença ou ausência da inoculação, além de dois controles, sem adição de potássio, um com e outro sem inoculação, aplicados em 4 repetições. Foram avaliados os teores de potássio e outros nutrientes no solo. O tratamento com olivina melilitito inoculado com rizobactérias favorece a solubilização de fosfato na maior dose. O remineralizador olivina melilitito, isolado ou inoculado com rizobactérias aumentou os teores de K+ e Ca2+ no solo nas doses intermediária e máxima (300 e 600 kg ha-1 de K2O), destacando esse remineralizador como fonte alternativa de potássio para as plantas.

Resumo A cultura da cana-de-açúcar Saccharum spp. (Poales: Poaceae) produz diferentes derivados para o mundo: açúcar, etanol e bioenergia. Apesar da aplicação de pesticidas, os insetos-praga ainda causam prejuízos econômicos, dentre eles a cochonilha rosada da cana-de-açúcar Saccharicoccus sacchari (Cockerell, 1895) (Hemiptera: Pseudococcidae) causando danos diretos e indiretos à planta. Este estudo avaliou a virulência de três espécies de nematoides entomopatogênicos (NEPs) e suas bactérias simbiontes contra a cochonilha rosada da cana-de-açúcar, em condições de laboratório. Quatorze tratamentos representados pelo controle (água destilada), Heterorhabditis bacteriophora Poinar, 1976 (HB EN01) (Rhabditida: Heterorhabditidae), Steinernema rarum (Doucet, 1986) (PAM25) e Steinernema carpocapsae Weiser, 1955 (All) (Rhabditida: Steinermatidae) nas concentrações de 25, 50, 75 e 100 juvenis infectantes (JIs)/inseto, e o produto químico padrão, tiametoxam, foram testados. Em um segundo experimento, a bactéria Photorhabdus luminescens (Thomas e Poinar, 1979), Xenorhabdus szentirmaii Lengyel, 2005 e Xenorhabdus nematophila (Poinar e Thomas, 1965) (Enterobacterales: Morganellaceae) em 3,0 x 109 células/ml foram avaliadas para cada tratamento. Dez repetições foram estabelecidas, cada uma contendo dez fêmeas/cochonilhas dentro de uma placa de Petri de 10 cm, totalizando 100 indivíduos/tratamento. Todos os tratamentos foram mantidos em condições estáveis (25±1 ºC, U 70±10%, no escuro). Todas as espécies de nematoides infectaram S. sacchari. Steinerma rarum (PAM25) proporcionou a maior mortalidade contra a cochonilha rosada da cana-de-açúcar (79,25%), seguida por H. bacteriophora (HB EN01) (58,25%) e S. carpocapsae (All) (42,50%) (P<0,001). As taxas de mortalidade causada por X. szentirmaii, P. luminescens e X. nematophila foram de 40, 45 e 20%, respectivamente. Steinerma rarum (PAM25) tem condições de ser um agente potencial a ser incorporado ao manejo integrado de pragas da cana-de-açúcar.

Abstract Sugarcane crops Saccharum spp. (Poales: Poaceae) produces different derivatives to the world: sugar, ethanol and bioenergy. Despite the application of pesticides, insect pests still cause economic losses, among these the pink sugarcane mealybug Saccharicoccus sacchari (Cockerell, 1895) (Hemiptera: Pseudococcidae) causing direct and indirect damage to the plant. This study assess the virulence of three entomopathogenic nematodes (EPNs) species and their symbiont bacteria against the pink sugarcane mealybug, under laboratory conditions. Fourteen treatments represented by control (distilled water), Heterorhabditis bacteriophora Poinar, 1976 (HB EN01) (Rhabditida: Heterorhabditidae), Steinernema rarum (Doucet, 1986) (PAM25) and Steinernema carpocapsae Weiser, 1955 (All) (Rhabditida: Steinermatidae) at concentrations of 25, 50, 75 and 100 infective juveniles (IJs)/insect, and the standard chemical product, thiamethoxam, were assayed. In a second experiment, the bacteria Photorhabdus luminescens (Thomas and Poinar, 1979), Xenorhabdus szentirmaii Lengyel, 2005 and Xenorhabdus nematophila (Poinar and Thomas, 1965) (Enterobacterales: Morganellaceae) at 3.0 x 109 cells/ml were assessed for each treatment. Ten replications were stablished, each one counting ten females/mealybugs inside a 10 cm Petri dish, amounting 100 individuals/treatment. All treatments were kept under stable conditions (25±1 ºC, H 70±10%, in the dark). All nematodes species infected S. sacchari. Steinerma rarum (PAM25) provided the highest mortality against the pink sugarcane mealybug (79.25%), followed by H. bacteriophora (HB EN01) (58.25%) and S. carpocapsae (All) (42.50%) (P<0.001). The mortality rate caused by X. szentirmaii, P. luminescens and X. nematophila were 40, 45 and 20%, respectively. Steinerma rarum (PAM25) has conditions to be a potential agent to be incorporate into the integrated pest management in sugarcane.

ABSTRACT Purpose: This study investigates the protective effect of cilostazol on the development and evolution of diabetic retinopathy in rats. Methods: Sixty male rats were divided into four groups: untreated nondiabetic rats, untreated diabetic rats, cilostazol-treated nondiabetic rats, and cilostazol-treated diabetic rats. The thickness of the internal limiting membrane to the outer limiting membrane, inner plexiform layer, inner nuclear layer, and outer nuclear layer were measured. The number of cell nuclei per 50-μm length in retinal sections was counted to quantify the degree of retinal cell loss. Results: The number of nuclei in the ganglion cell layer was significantly higher in untreated nondiabetic rats (p<0.05). The mean number of nuclei in the cilostazol-treated nondiabetic rats was significantly higher than that in the cilostazol-treated diabetic rats (p<0.05). The cilostazol-treated nondiabetic rats had a significantly higher mean nuclei count in the inner nuclear layer and inner plexiform layer as compared with the other groups (p<0.05). The total mean retinal thickness of the cilostazol-treated nondiabetic rats was significantly higher than that of cilostazol-treated diabetic rats and untreated diabetic rats (p<0.05). Conclusion: By decreasing the loss of ganglion cells and reducing the sensorineural atrophy in the internal retinal layers, cilostazol had a protective effect against changes caused by diabetic retinopathy in diabetic rats.

RESUMO Objetivo: O objetivo deste estudo foi investigar o efeito protetor do cilostazol no desenvolvimento e na evolução da retinopatia diabética em ratos. Métodos: Sessenta ratos machos foram divididos em 4 grupos: ratos não-diabéticos não-tratados, ratos diabéticos não-tratados, ratos não-diabéticos tratados com cilostazol e ratos diabéticos tratados com cilostazol. A espessura da membrana limitante interna à membrana limitante externa, a camada plexiforme interna, a camada nuclear interna e a camada nuclear externa foram medidas. Para quantificar o grau de perda de células da retina, foi contado o número de núcleos de células por 50 μm de comprimento em secções retinianas. Resultados: O número de núcleos no GCL foi significativamente maior em Ratos não-diabéticos não-tratados com cilostazol (p<0,05). O número médio de núcleos em Ratos não-diabéticos tratados com cilostazol foi significativamente maior do que em Ratos diabéticos tratados com cilostazol (p<0,05). A contagem média de núcleos em camada nuclear interna e camada plexiforme interna de ratos não-diabéticos tratados com cilostazol foi significativamente maior do que nos outros grupos (p<0,05). A espessura retiniana média total de Ratos não-diabéticos tratados com cilostazol foi significativamente maior do que em Ratos diabéticos tratados com cilostazol e Ratos diabéticos não-tratados (p<0,05). Conclusão: Os resultados demonstraram que o cilostazol teve um efeito protetor contra as alterações causadas pela retinopatia diabética em ratos diabéticos, diminuindo a perda de células ganglionares e reduzindo a atrofia neurossensorial nas camadas retinianas internas.

ABSTRACT Zinc is an essential micronutrient for plant metabolism and has been studied in several crops of economic interest. However, there is no evidence of its use in coconut crops. The objective of this study was to evaluate the influence of foliar zinc fertilization with doses of zinc on dwarf green coconut seedlings based on their nutritional status, growth attributes, and gas exchange. The experimental design consisted of randomized blocks, and the treatments consisted of different zinc doses (0, 5, 10, 15, 20, and 25 g per plant) with five replicates. Seedlings were positively influenced by zinc dose, mainly in terms of growth variables and gas exchange. Zinc fertilization reduced iron and manganese content and increased zinc concentrations in the leaf tissue. Zinc fertilization promoted an increase in leaf area, height, shoot dry mass, and total dry mass. Furthermore, zinc fertilization improved photosynthesis, transpiration, stomatal conductance, internal CO2 concentration, instantaneous water use efficiency, and intrinsic water use efficiency. The improvement in these growth indices and gas exchange, in most variables, was up to an estimated dose of approximately 16 g of zinc per plant and decreased with increasing doses.

RESUMO O zinco é um micronutriente de importância essencial para o metabolismo vegetal, é estudado para diversas culturas de interesse econômico, porém sem evidências de estudo para a cultura do coqueiro. Objetivou-se com este estudo avaliar a influência da fertilização com doses de zinco via foliar em mudas de coqueiro anão verde, por meio do estado nutricional, atributos de crescimento e trocas gasosas. O delineamento experimental foi em blocos ao acaso, e os tratamentos foram constituídos por doses de zinco (0, 5, 10, 15, 20 e 25 g por planta), com cinco repetições. As mudas foram influenciadas positivamente pelas doses de zinco principalmente nas variáveis de crescimento e nas trocas gasosas. No estado nutricional afetou de maneira decrescente o ferro e o manganês e aumentou o zinco no tecido foliar. O zinco proporcionou incrementos na área foliar, altura de plantas, massa seca da parte aérea e massa seca total. Além disso, melhorou a fotossíntese, transpiração, condutância estomática, concentração interna de CO2, eficiência instantânea do uso da água e eficiência intrínseca do uso da água. A melhora nesses índices de crescimento e trocas gasosas, na maioria das variáveis, foi até a dose estimada de aproximadamente 16 g de zinco por planta e diminuiu com o aumento das doses.

ABSTRACT Soil erosion studies using rainfall simulators are generally expensive and time consuming. Thus, the aim of this study was to develop a prototype of an automatic runoff collector, capable of real-time quantifying runoff volume and soil loss in field trials using a rainfall simulator. The used sensors were chosen based on the type A uncertainty computed from different volumes of water and concentrations of sediment. Through specific programming, the runoff volume, sediment concentrations and the time of occurrence of the collections corresponding to each 200 cm³ of runoff were recorded on a micro-SD card. The robustness of the calibration and the programming developed were also evaluated in the Arduino Mega® 2560 microcontroller. The pressure (PSI.420) and turbidity (ST100) sensors were selected for developing the prototype, which was evaluated in the field with the InfiAsper rainfall simulator. Then, the data collected automatically by the sensors were compared to those obtained by manual measurement. The automatic runoff collector equipped with the PSI.420 and ST100 sensors has potential to obtain and store runoff data, and it was effective in evaluating the erosion process, generating mean errors of 12.25 and 13.16% for runoff volume and soil loss, respectively. The proposed prototype has a low cost of manufacture, in addition to optimizing the collection of erosion data in studies with rainfall simulators.

RESUMO Estudos relacionados à erosão do solo usando simuladores de chuva são geralmente onerosos e demorados. Assim, o objetivo deste estudo foi desenvolver um protótipo de coletor automático de escoamento superficial, capaz de quantificar em tempo real o volume de escoamento superficial e a perda de solo em ensaios de campo utilizando um simulador de chuva. Os sensores utilizados foram escolhidos com base na incerteza tipo A calculada a partir de diferentes volumes de água e concentrações de sedimentos. Por meio de programação específica, o volume da enxurrada, as concentrações de sedimentos e o tempo de ocorrência das coletas correspondentes a cada 200 cm³ de enxurrada foram registrados em um cartão micro-SD. A robustez da calibração e a programação desenvolvida também foram avaliadas no microcontrolador Arduino Mega® 2560. Os sensores de pressão (PSI.420) e de turbidez (ST100) foram selecionados para o desenvolvimento do protótipo, o qual foi avaliado em campo com o simulador de chuva InfiAsper. Em seguida, os dados coletados automaticamente pelos sensores foram comparados com os obtidos por medição manual. O coletor automático equipado com os sensores PSI.420 e ST100 tem potencial para obter e armazenar dados de escoamento, e foi eficiente na avaliação do processo erosivo, gerando erros médios de 12,25 e 13,16% para volume de escoamento e perda de solo, respectivamente. O protótipo proposto possui baixo custo de fabricação, além de otimizar a obtenção de dados de erosão em estudos com simuladores de chuva.

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Objectives: To examine drug overdose records in Brazil from 2000 to 2020, analyzing trends over time in overdoses and overall sociodemographic characteristics of the deceased. Methods: Using data from the Brazilian Mortality Information System (Sistema de Informações sobre Mortalidade), we identified records from 2000-2020 in which the underlying cause-of-death was one of the following codes: X40-X45 (accidental poisoning), X60-X65 (intentional poisoning), or Y10-Y15 (undetermined intentionality poisoning). The Brazilian dataset included 21,410 deaths. We used joinpoint regression analysis to assess changes in trends over time. Results: People who died of drug overdoses in Brazil between 2000 and 2020 had a mean age of 38.91 years; 38.45% were women, and 44.01% were identified as White. Of the overdose deaths, 44.70% were classified as intentional and 32.12% were classified as unintentional. Among the identified drugs, stimulants were the most common class. However, most records did not report which drug was responsible for death. Conclusion: Sociodemographic trends in overdose deaths in Brazil must guide country-specific policies. Nevertheless, data collection protocols must be improved, particularly regarding the drug used in overdoses.

Resumo No Brasil, avanços consistentes ocorreram em direção à cobertura universal após a criação do Programa Saúde Família (PSF), principal estratégia para a ampliação do acesso de primeiro contato e de mudança do modelo assistencial no Brasil, fortalecido a partir da criação Piso de Atenção Básica (PAB), com recursos destinados exclusivamente à atenção básica, transferidos aos municípios de forma regular e automática. O cadastramento da população é um dos fundamentos do trabalho na Estratégia Saúde da Família (ESF), objetivando conhecer as famílias adscritas às equipes. A instituição do Programa Previne Brasil em novembro de 2019 estabeleceu um novo modelo de financiamento de custeio da APS, tendo como um de seus componentes a capitação ponderada, cujo modelo de remuneração é calculado com base no número de pessoas cadastradas. O objetivo do estudo foi analisar a evolução da população cadastrada na APS após a criação do incentivo de capitação ponderada, considerando o cadastro nos municípios e o seu comportamento nas diferentes tipologias municipais rural-urbano e o porte populacional. O estudo demonstrou que em 76,1% dos municípios houve aumento de cadastros no período analisado, independentemente da tipologia rural-urbano e do porte populacional dos municípios.

Abstract In Brazil, consistent advances occurred towards universal coverage after the creation of the Family Health Program (FHP), the main strategy for expanding first contact access and changing the care model in Brazil, strengthened from the creation of The Primary Care Floor (PAB), with resources exclusively for Primary Care, transferred to the municipalities on a regular and automatic basis. The registration of the population is one of the fundamentals of work in the Family Health Strategy (ESF), aiming to know the families enrolled in the teams. The institution of the Previne Brasil Program in November 2019 established a new funding model for PHC, with weighted capitation as one of its components, whose remuneration model is calculated based on the number of people registered. The aim of this study was to analyze the evolution of the population registered in PHC after the weighted capitation incentive creation, considering the registration in the municipalities and their behavior in the different rural-urban municipal typologies and the population size. The study showed that in 76.1% of the municipalities there was an increase in registrations in the analyzed period, regardless of the rural-urban typology and population size of the municipalities.

Abstract Visible-light communication (VLC) is a technique that employs light-emitting diodes (LEDs) and photodiodes to enable communication in indoor scenarios. VLC has gathered increasing attention due to its potential for data transmission across a broad unregulated spectrum (430-790 THz). One of VLC’s primary objectives is to utilize pre-existing LED infrastructures as access points. In this investigation, we assess the performance of an indoor VLC link by measuring the illumination characteristics of commercial LED luminaire. The results are utilized to design an electronic transmission and reception circuit. An analysis was conducted to identify the optimal operating point that ensures adequate lighting and reliable communication. The designed circuits exhibited a bandwidth of 50 MHz at -3 dB. Characterization of the luminaire demonstrated that a single luminaire provided the illumination (486 lx) within the recommended range at 1.6 m. For data transmission, the variable pulse position modulation (VPPM) and the orthogonal frequency-division multiplexing (OFDM) were employed in different configurations. The bit error rate (BER) results, with a threshold of ≤ 10-3, revealed that VPPM performed best at a distance of 1.9 m with a rate of 12.5 Mbps. Conversely, OFDM modulation achieved optimal performance at 1.75 m, providing a transmission rate of 30 Mbps.

Research to identify plant bioactive compounds led to the evolution of extraction methods. This study optimized ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) to extract the flavonoids of Croton grewioides Baill. species contributing to characterize the polar extract profile and understand the antioxidant potential of these plant constituents. The use of experimental design and statistical treatments enabled the determination of the ideal conditions for each technique. The extracts of five accessions of C. grewioides were obtained under the optimized extraction conditions and were analyzed using ultra high-resolution mass spectrometry (FT-Orbitrap MS) operating at negative ionization mode for flavonoids detection. The accurate experimental mass obtained to the main compounds was used to attribute the molecular formula. Chemical structures of the main compounds detected were proposed using structure data bases. Chemometric analysis were performed with two FT-Orbitrap MS spectra samples using the identified metabolites and, the antioxidant activity data, showing that for this species the MAE was most effective in extracting the antioxidant compounds. It was possible to propose the structures for forty compounds in the C. grewioides extracts, demonstrating the excellent performance of the FT-Orbitrap MS in providing information on the chemical profile of polar compounds in plant extracts. methods ultrasoundassisted ultrasound assisted UAE (UAE microwaveassisted microwave (MAE Baill constituents technique C highresolution high resolution FTOrbitrap FT Orbitrap detection formula bases

Resumo O presente estudo teve como objetivo comparar por grupo etário, sexo, nível competitivo, posição de jogo e anos de prática de futebol dos futebolistas moçambicanos em função das orientações cognitivas para o ego e tarefa. A amostra foi constituída por 443 praticantes de futebol pertencentes a 32 clubes, sendo 196 (44.2%) femininos e 247 (55.8%) masculinos, com idades compreendidas entre os 16 e os 37 anos. Para a realização do estudo foi aplicada a versão traduzida e validada para a língua portuguesa do Task and Ego Orientation in Sport Questionnaire - TEOSQ. Os resultados evidenciam que os futebolistas obtiveram valores altos quanto à orientação cognitiva para a tarefa (4.01 ± 1.07) e moderadamente baixos quanto à orientação para o ego (2.72 ± 1.17). Face aos resultados, conclui-se que o tipo da orientação cognitiva da prática desportiva é um factor importante que distingue os futebolistas moçambicanos. Há predominância de uma orientação cognitiva voltada para a tarefa nestes futebolistas, favorecendo a uma maior manifestação de atitudes desportivas indo de acordo com as evidências literárias em outros contextos de futebol.

Abstract The present study aimed to compare by age group, sex, competitive level, game position, and years of soccer practice of Mozambican soccer players as a function of cognitive orientations for the ego and task. The sample consisted of 443 soccer players from 32 clubs, 196 (44.2%) female and 247 (55.8%) male, aged between 16 and 37 years. To carry out the study, the version translated and validated into Portuguese of the Task and Ego Orientation in Sport Questionnaire - TEOSQ was applied. The results show that soccer players obtained high values for cognitive task orientation (4.01 ± 1.07) and moderately low values for ego orientation (2.72 ± 1.17). Given the results, it is concluded that the type of cognitive orientation of sports practice is an important factor that distinguishes Mozambican footballers. There is a predominance of a task-oriented cognitive orientation in these footballers, favoring a greater manifestation of sporting attitudes following the literary evidence in other football contexts.
