ABSTRACT Objective: To compare the outcomes of surgical stabilization of pediatric supracondylar humeral fractures with the use of crossed Kirschner wires versus divergent lateral pinning wires. Methods: This is a systematic review with meta-analysis carried out by searching the MEDLINE/PubMed, Science Direct and Scielo databases. In these, the search for journals was carried out between January and August 2023, where 695 studies were found. To assess the quality of the studies, the Jadad and the MINORS scales were used.. The selection and reading of relevant articles were carried out by the researchers and 11 studies met the selection criteria. Results: From the 11 selected studies, 963 patients who met the criteria for the surgical treatment of these fractures were grouped. After the statistical analysis, we found that the ulnar nerve injury had a higher incidence when the crossed-K wire technique was used; and the lateral fixation is safer for the ulnar nerve. Conclusion: Both fixation techniques determine good functional results. However, fixation with lateral Kirschner wires proves to be safer considering the risk of iatrogenic injury to the ulnar nerve. Crossed-K wire fixation is more effective in terms of stability and maintenance of fracture reduction. Level of Evidence II, Systematic Review of Level II or Level I Studies with discrepant results.

Abstract Sealing systems that provide greater permeability to gasses can favor plant development in vitro. This study aimed to evaluate the effectiveness of a low-cost sealing system that allows different CO2-exchange rates [CO2-ER] to promote the in vitro growth of mother-of-millions (Kalanchoe delagoensis). Nodal segments of K. delagoensis were surface sterilized with sodium hypochlorite (2.5% active chlorine) and inoculated in culture vessels with Murashige and Skoog (MS) medium, sealed with rigid polypropylene lids with one (code: 1M; CO2-ER 21 μL L−1s−1) or two (code: 2M; CO2-ER 25 μL L−1s−1) gas-permeable membranes. In the control, the culture vessels were sealed with rigid polypropylene lids without membrane (code: 0M; CO2-ER 14 μL L−1s−1). After 45 days of culture, growth parameters were measured. Plants kept in culture vessels with 0M and 1M lids had a significant increase in the total plant length, main root, aerial part, and number of nodes when compared to the 2M sealing system. The number of leaves and plantlets along the leaf margin was 35.52% and 43.69% higher in plants grown in culture vessels with a 1M sealing system. In conclusion, sealing systems that allow gas exchange rates of up to 21 μL L−1s−1 (0M and 1M) provided the greatest in vitro development of mother-of-millions. lowcost low cost CO2exchange COexchange CO2 CO CO2ER COER ER [CO2-ER motherofmillions mother millions Kalanchoe delagoensis. . delagoensis) K 2.5% 2 5 (2.5 chlorine MS (MS medium code (code M L1s1 Ls L 1s 1 s gaspermeable permeable membranes control L−1s−1. 4 measured length root part 3552 35 52 35.52 4369 43 69 43.69 conclusion L−1s− motherofmillions. millions. 2.5 (2.

Resumo Este artigo discute o comportamento político dos empresários industriais brasileiros durante o Governo Dilma Rousseff (2011-16), a partir de dois estudos de caso de importantes setores: Construção Civil e Autopeças. Fundamentado na hipótese de que houve um deslocamento político do empresariado industrial desde o apoio em 2011 até a conformação de uma “unidade burguesa antidesenvolvimentista” em oposição ao governo, realizamos entrevistas semiestruturadas, levantamento de dados e de posicionamentos públicos. A análise corrobora a hipótese de deslocamento político no período, e aponta como uma das explicações o acirramento dos conflitos distributivos entre capital e trabalho, expresso nas declarações empresariais e nos aumentos da participação das remunerações no valor adicionado bruto e do número de greves. 201116, 201116 16 , (2011-16) setores Autopeças 201 unidade antidesenvolvimentista governo semiestruturadas públicos período trabalho greves 20111 1 (2011-16 20 (2011-1 2 (2011- (2011 (201 (20 (2 (

Abstract This article discusses the political behavior of Brazilian industrial entrepreneurs during Rousseff’s Government (2011-16), based on two case studies of important sectors: Civil Construction and auto parts industry. Following the hypothesis that there was a political displacement from the industrial entrepreneurs support in 2011, towards the shaping of an “anti-development bourgeois unity” in opposition to the government, we conducted semi-structured interviews and data collection. The analysis confirms the hypotheses of the industrials political displacement in the period, and points as one of the explanations the intensification of distributive conflicts between capital and labor, expressed in the businesspeople statements and in the increase of the wage-share in the Gross Value Added (GVA) and of the number of strikes.

RESUMO O gerenciamento automático de produtividade (APM) presente no trator agrícola é uma ferramenta importante que auxilia na operação, aumentando a eficiência e rendimento energético. O objetivo do experimento foi comparar o desempenho operacional e energético de um trator articulado de 373 kW equipado com APM e com o modo manual da transmissão e rotação do motor, sob diferentes velocidades reais. O experimento foi conduzido no delineamento de blocos casualizados em esquema de parcelas subdivididas, sendo as parcelas constituídas de dois modos de transmissão (manual e automático) e as subparcelas de quatro velocidades reais (4, 6, 8 e 10 km h-1), com cinco repetições, totalizando 40 unidades experimentais. Foram monitorados a patinagem dos rodados, rotação do motor, consumo horário e específico de combustível, força, potência e rendimento na barra de tração, velocidade operacional e eficiência térmica do motor. Os dados coletados foram submetidos à análise de variância, sendo o primeiro fator analisado pelo teste de Tukey, e o segundo fator e as interações por análise de regressão. No modo automático a rotação do motor e a patinagem dos rodados foram menores sem comprometer as demais variáveis. Além disso, este modo, a 4 e 6 km h-1, demonstrou uma vantagem energética, que requer menor consumo de combustível por hora. Além disso, o modo manual apresentou maior eficiência térmica em velocidades mais baixas quando comparado com o modo automático, que apresentou um aumento linear.

ABSTRACT Automatic production management (APM) is a tool that assists in the operations of agricultural tractors, increasing yield and energy efficiency. The objective of the experiment was to compare the energy and operational performance of a 373-kW articulated tractor equipped with APM and manual mode of engine transmission and rotation, across different real-world speeds. The experiment was conducted in a randomized block design with five replicates, using a split-plot arrangement with two system modes (manual and automatic) in the plots and four real-world speeds (4, 6, 8, and 10 km h-1) in the subplots, totaling 40 experimental units. The evaluated variables were: wheel slippage; engine rotation; hourly and specific fuel consumptions; drawbar force, power, and yield; operating speed; and engine thermal efficiency. The variance of the data was analyzed using Tukey’s test for the first factor, and regression analysis for the second factor and interactions. The automatic mode showed lower engine rotation and wheel slippage without compromising the other variables. The use of this mode showed energy advantages at 4 and 6 km h-1 by resulting in less fuel consumption per hour. In addition, the manual mode presented higher thermal efficiency at lower speeds than the automatic mode, which showed a linear increase.

Resumo Introdução: A deiscência anastomótica (DA) é uma complicação grave no pós-operatório precoce da esofagectomia e gastrectomia total, pela sua elevada mortalidade. As próteses metálicas autoexpansíveis (PMAE) desempenham um papel fundamental no tratamento das DA. Na literatura, há apenas um caso descrito sobre a utilização de um Mega-Stent no contexto de DA, que não complicação bariátrica. Os autores reportam uma série de dois casos com diferente aplicação do Mega-Stent esofágico no tratamento de DA. Descrição do caso: Caso 1: Homem de 67 anos, submetido a esofagectomia por carcinoma epidermóide do esófago distal. O período pós-operatório precoce foi complicado de DA com fístula gastro-pleural. Inicialmente foi colocado um clip OTSC no orifício da deiscência com insucesso técnico e clínico, sendo posteriormente utilizado o Mega-Stent, posicionado desde o esófago até ao bulbo duodenal. Estudos contrastados posteriores confirmaram resolução da DA. Caso 2: Mulher de 86 anos, submetida a gastrectomia total com reconstrução em Y-Roux e esofagojejunostomia por adenocarcinoma gástrico, complicada de DA. Neste contexto foi colocada uma PMAE parcialmente coberta (PMAE-PC) sobre a área da anastomose. A tomografia computorizada subsequente demonstrou persistência de extravasamento. Foi colocada uma segunda PMAE-PC, com posterior resolução da DA. Semanas depois, ambas as PMAE-PC apresentavam tecido de granulação nos topos, tendo sido colocado o Mega-Stent (técnica stent-in-stent) e decorridas duas semanas, todas as próteses foram facilmente extraídas, confirmando-se sucesso no tratamento da DA. Discussão/conclusão: A utilização de PMAE nas DA constitui uma técnica terapêutica segura e bem estabelecida, contudo passível de apresentar limitações tais como a migração ou incapacidade de cobrir totalmente DA de maiores dimensões. O Mega-Stent esofágico pode constituir uma ferramenta útil na terapêutica endoscópica destes doentes.

Abstract Introduction: Anastomotic leak (AL) is a dangerous complication in the early postoperative period after total gastrectomy or esophagectomy being associated with high mortality. Self-expandable metal stents (SEMS) play a significant role in AL management. Only one case report described the use of Mega-Stent in AL setting. The authors report a two-case series with different applications of a Niti-S esophageal Mega-Stent in AL management. Case Report: Case 1 is a 67-year-old male who underwent an esophagectomy due to a squamous cell carcinoma of the distal esophagus. The early postoperative period was complicated with AL and gastropleural fistula. Initially, an OTSC was deployed in the dehiscence but failed to resolve AL. The esophageal Mega-Stent was further placed in-between the esophagus and the bulbus. Post-stenting contrast studies confirmed no further AL. Case 2 is an 86-year-old woman who underwent total gastrectomy with roux-en-y esophagojejunostomy due to a gastric adenocarcinoma, complicated with AL. A partially covered metal stent (PCMS) was placed to cover the anastomosis. Computed tomography confirmed leakage persistence and a second PCMS was deployed, resolving the AL. Several weeks later, both PCMSs presented ingrowth from granulation tissue. An esophageal Mega-Stent was placed (stent-in-stent technique) and 2 weeks later, all stents were removed, with no AL recurrence. Discussion/Conclusion: SEMS placement for AL is a safe, well-established therapeutic technique. Limitations include stent migration and incomplete cover of large AL. Mega-Stent can be an emerging tool for endoscopic AL management.

ABSTRACT. Knowledge of the relationship between the equilibrium moisture content of the product and the air that involves it is essential to guarantee product quality and preserve its characteristics during storage. This trend can be studied by sorption isotherms. Thus, this study aimed to obtain desorption and adsorption isotherms of soybean grains to determine the mathematical model that best fits the experimental data and analyze the hysteresis phenomenon. Soybean grains with a moisture content of 21.95% (db) were used to verify the desorption process. The grains were dried until 3.50% (db) for the adsorption process. The static-gravimetric method was employed to determine the equilibrium moisture content of the grain at different temperatures (10, 20, 30, 40, and 50°C) and relative humidity levels (0.10 to 0.92%). Eight mathematical models were fitted to the experimental data. The modified Halsey model satisfactorily represented the desorption and adsorption phenomena of soybean grains. The equilibrium moisture content of soybean grains increased along with an increment in water activity. The increase in temperature led to a reduction in the equilibrium moisture content of soybean grains at a constant water activity. The equilibrium moisture content values obtained by desorption are higher than those obtained by adsorption, indicating the hysteresis phenomenon at the studied temperature range. The isotherms obtained for the desorption and adsorption process were classified as type III because of the high oil content in soybean grains.

ABSTRACT The obstacles in Phakopsora pachyrhizi management result especially from susceptible soybean genotypes and resistant fungal strains. The objective of the current study was to evaluate the applicability of the emission of extremely low and specific frequencies by Effatha technology in the soybean Asian rust control, nutrition, and its impact on yield. The in-vivo test followed the detached leaves method, with six treatments: frequencies 1 and 2 individually and in association; the conventional chemical treatment (fungicide azoxystrobin + benzovindiflupyr); and witnesses in presence and absence of the fungus. Frequency 1 relates to inhibition of the enzyme succinate dehydrogenase and 2 to ubiquinone oxidase. In the field, frequencies 1 and 2 associated (with the same fungicidal action of the in-vivo study); nutritional frequency; application of azoxystrobin + benzovindiflupyr + mancozeb, and control without application were evaluated. In vivo, the fungicide provided 85% control of the disease symptoms, against 65% of frequencies 1 and 2 in association, which showed a higher efficiency compared to the isolated frequencies. In the field, the rate of increase of symptoms were reduced by all treatments compared to the control. At the end of the soybean cycle, the conventional fungicide resulted in 33% severity against 56% of frequencies 1 and 2 associated, and 69.2% of the control. The emission of the frequency for increased nutrient efficiency stood out positively on yield in relation to all the other ones. The conventional application provided the highest weight of 1,000 grains, possibly a direct reflection of the better control of the disease. strains nutrition invivo vivo method association benzovindiflupyr) fungus oxidase field study) mancozeb evaluated 85 65 cycle 33 56 692 69 69.2 ones 1000 000 1,00 grains 8 6 3 5 69. 100 00 1,0 10 0 1,

ABSTRACT Laboratory chemical analysis of leaf samples can be costly and time-consuming, making it impractical for assessing crop variability. To address this challenge, researchers have focused on developing non-invasive tools that aid nitrogen (N) management, maximizing profits, minimizing environmental impact, and meeting market demands. This study aimed to develop a computer vision-based classifier system for assessing the N status in bean crops. An experiment was conducted in a greenhouse, involving five treatments (0%, 50%, 100%, 150%, and 200% N of the recommended dose) with six replications, totaling 30 pots containing six seedlings of Phaseolus vulgaris L. beans in four different phenological phases (V4, R5, R6, and R7). Digital RGB images of the bean canopies were captured using a camera at four-week intervals (30, 37, 44, and 51 days after emergence - DAE). The images were manually labeled to create an image database based on N status. Four different computational N status classifiers were developed by training a Convolutional Neural Network (CNN), one for each DAE. The classifiers were evaluated using confusion matrix metrics (accuracy, precision, and recall), resulting in an overall accuracy of about 80% when evaluating nitrogen status at five levels. Improved results were achieved by grouping the saturation classes of the 150% and 200% treatments with the 100% class (>=100% class), yielding an accuracy of 97% for 30 and 44 DAE. Promising results aside, this method opens new possibilities for improvement and application to other treatments, electromagnetic spectrum bands, and crops. timeconsuming, timeconsuming time consuming, consuming time-consuming variability challenge noninvasive non invasive (N management profits impact demands visionbased vision crops greenhouse 0%, 0 (0% 50 50% 100 150 200 dose replications 3 L V4, V4 V (V4 R5 R R6 R7.

ABSTRACT Sandy-textured soils are naturally more vulnerable to the erosion process and their exploitation, although possible, is often performed inappropriately, favoring its degradation. In this context, this study aimed to classify the rainfall erosivity in a region of sandy soils to identify critical situations of soil and water loss and also correlate it with rainfall data to assess whether there is temporal dependence of this variable using geostatistical techniques. The potential for alternative and sustainable production systems to be used in regions with sandy soils was also analyzed. Historical data of precipitation in the study region were analyzed to determine the average monthly and annual erosivity indices, which were classified and its temporal dependence was assessed by applying geostatistics. NDVI data from satellite images were used to investigate the soil cover pattern in different production systems. Geostatistics was adequate for the analysis of rainfall erosivity, which showed moderate to strong temporal dependence. It was classified between strong and very strong and was highly dependent on precipitation, with events of higher erosion potential between October and March in the studied region. The vicious circle of degradation of sandy soils, such as those of the Bolsão region of Mato Grosso do Sul, Brazil, can be modified by adopting alternative and sustainable production systems that value the maximization of soil cover.

Abstract This investigation discusses the relationship between the body culture of movement and two rock art scenes located in the Parque Nacional Serra da Capivara, (Serra da Capivara National Park) - PNSC, in the state of Piauí, Brazil. The scenes depict a flic flac and a human pyramid, which have been accepted in contemporaneity as gymnastics and acrobatics. An interdisciplinary theoretical apparatus based on Physical Education and its relationships with Archeology and Anthropology was used in the analysis. The analysis is based on inferences, as nothing guarantees that the hands that portrayed the scenes had the same intentions as the authors of the research. One of the findings understands that motor skills helped the daily demands of adversity for the survival of the group. In another point of view, based on the Ilinx concept, flic flac satisfies the search for a trance/vertigo vital to ritualistic liturgy, and the human pyramid serves the imperative task of consolidating cooperative bonds and trust between its members in a hostile environment.

RESUMO Introdução: A fratura da diáfise da tíbia é a fratura mais comum dentre os ossos longos, sendo o tratamento padrão a fixação com haste intramedular (HIM). Independentemente do desenvolvimento da técnica cirúrgica, a pseudoartrose continua prevalente. Objetivo: Avaliar a associação entre o tamanho e o desvio da cunha, os desvios dos fragmentos principais do tipo 42B2 e a incidência de pseudoartrose. Métodos: Avaliamos, retrospectivamente, todos os pacientes com fraturas tipo 42B2 tratados com hastes intramedulares entre janeiro de 2015 e dezembro de 2019. Seis parâmetros radiográficos foram definidos para as radiografias pré-operatórias nas incidências anteroposterior (AP) e perfil. Outros seis parâmetros foram definidos para as radiografias pós-operatórias em 3, 6 e 12 meses de acompanhamento pós-operatório. O Escore Radiográfico de União para as Fraturas da Tíbia (RUST) foi o instrumento usado para avaliar a consolidação óssea. Resultados: Dos 355 pacientes com fraturas da diáfise da tíbia, 51 foram incluídos no estudo. Os pacientes incluídos foram 41 (82,0%) do sexo masculino, com idade média de 36,7 anos, 37 (72,5%) com fraturas expostas e 28 (54,9%) com lesões associadas. Após análise estatística, os fatores que se correlacionaram significativamente com a não consolidação foram a altura da cunha > 18 mm, o deslocamento translacional pré-operatório da fratura na incidência AP > 18 mm e a distância final da cunha em relação à sua posição anatômica original após a cravação do MI > 5 mm. Conclusão: Os fatores de risco para a pseudartrose relacionada com a fratura em cunha e42B2 são a altura da cunha > 18 mm, a translação inicial na vista AP da fratura > 18 mm e a distância > 5 mm da cunha em relação à sua posição anatómica após a fixação IM.

ABSTRACT Introduction: Tibial shaft fracture is the most common long-bone fracture, and the standard treatment is intramedullary (IM) nail fixation. Regardless of the development of this technique pseudoarthrosis remains prevalent. Objectives: Evaluate the correlation between wedge fragment size and displacement, displacement of the main fragments of the 42B2 type, and pseudoarthrosis incidence. Methods: We retrospectively assessed all patients with 42B2 type fracture treated with IM nailing between January, 2015 and December, 2019. Six radiographic parameters were defined for preoperative radiographs in the anteroposterior (AP) and lateral views. Another six parameters were defined for postoperative radiographs at three, six, and 12 months. The Radiographic Union Score for Tibial Fractures score was used to assess bone healing. Results: Of 355 patients with tibial shaft fractures, 51 were included in the study. There were 41 (82.0%) male patients, with a mean age of 36.7 years, 37 (72.5%) had open fractures, and 28 (54.9%) had associated injuries. After statistical analysis, the factors that correlated significantly with nonunion were wedge height > 18 mm, preoperative translational displacement of the fracture in the AP view > 18 mm, and final distance of the wedge in relation to its original anatomical position after IM nailing > 5 mm.
