COLHEITA MECANIZADA DE SOJA EM FUNÇÃO DA PLATAFORMA DE CORTE EM ÁREA COM E SEM DESSECAÇÃO

Soyabean harvest is the most importante step of the production cicle, practice that influences directly on the final crop yield, in a operation wich is accomplished on machines that has advanced tecnology. The objective of this presente work was evaluated the losts of grain in the mecanize soyabean harvest in area with and without desiccation, and harvesters with platforms cutting conventional and "draper". The experiment ws accomplished in the minicipality of Uirapuru - Goiás, in complety casualized design, 2x2 factorial scheme, being two harvesters with differents types of cutting plataform (conventional and “draper”) in two area treatments (desiccated and not desiccated) with 10 repetition in each treatment. Cutting platform losses,internal losses, total losses of the harvester were measured, harvester speed, grain moisture and fuel consumption of the machine. The harvesting operation in a desiccated area allowed for lower fuel consumption, making it possible to maintain the harvesting operation at a more uniform speed, in addition to providing lower internal losses in the harvester. Average losses on the platform, internals, and totals harvest of 13.09 kg ha-1, 5.30 kg ha-1 and 18.38 kg ha-1 were obtained, respectively. The harvesting operation in a desiccated area allowed for lower fuel consumption, making it possible to maintain the harvesting operation at a more uniform speed, in addition to providing lower internal losses in the harvester.A colheita da soja é uma das etapas de maior importância durante o ciclo de produção, prática que influencia diretamente no rendimento final da lavoura, numa operação que é realizada em máquinas onde se dispõe de avançada tecnologia. O objetivo do presente trabalho foi avaliar as perdas de grãos na colheita mecanizada de soja em área com e sem dessecação, e colhedoras com plataformas de corte convencional e “draper”. O experimento foi realizado no município de Uirapuru - GO, em delineamento inteiramente casualisado, esquema fatorial 2x2, sendo duas colhedoras com diferentes tipos de plataforma de corte (convencional e “draper”) e dois tratamentos da área (dessecada e não dessecada) com 10 repetições por tratamento. Foram mensuradas as perdas na plataforma de corte, perdas internas, perdas totais da colhedora, velocidade da colhedora, umidade dos grãos e consumo de combustível da máquina. Obteve-se perdas médias na plataforma, internas e totais de colheita de 13,09 kg ha-1, 5,30 kg ha-1 e 18,38 kg ha-1, respectivamente. A operação de colheita em área dessecada permitiu um menor consumo de combustível, possibilitando manter a operação de colheita em velocidade mais uniforme, além de propiciar menores perdas internas na colhedora

PERDAS QUANTITATIVAS NA COLHEITA MECANIZADA DE SOJA EM FUNÇÃO DAS REGULAGENS INTERNAS DA MÁQUINA

The increase in agricultural production began to demand greater quality and speed in the harvest, since the soybean harvest is a process that directly influences the final yield, and must be carried out with minimal losses. The objective of this work was to evaluate soybean harvest losses in concave opening and rotor rotation settings. The trial was conducted in March 2022, at the Segredo farm, in Nova Crixás. The design used was completely randomized in a 2x2 factorial scheme, with 2 concave settings (12 mm and 14 mm) and two threshing rotor rotations (526 rpm and 620 rpm), with ten replications per treatment. Natural losses (PN), platform losses (PP), internal losses (PI), total machine losses (PTM), total harvest losses (PTC) and grain moisture were evaluated. The data were submitted to statistical process control with the creation of control charts by variables. The natural losses were 9.26 kg ha-1, totaling 58.03% of total harvest losses. The platform losses were on average 4.22 kg ha-1, representing 62.99% of the machine's total losses, which were still composed of internal losses, with 2.48 kg ha-1, with no differences between treatments, falling below acceptable limits.O aumento da produção agrícola passou a exigir maior qualidade e rapidez na colheita, já que a colheita da soja é um processo que influencia diretamente no rendimento final, devendo ser executada com o mínimo de perdas. O objetivo deste trabalho foi avaliar as perdas na colheita de soja em regulagens de abertura de côncavo e rotação do rotor. O ensaio foi conduzido em março de 2022, na fazenda Segredo, em Nova Crixás. O delineamento utilizado foi o inteiramente casualizado em esquema fatorial 2x2, sendo 2 regulagens de côncavo (12 mm e 14 mm) e duas rotações do rotor de trilha (526 rpm e 620 rpm), com dez repetições por tratamento. Foram avaliadas as perdas naturais (PN), perdas de plataforma (PP), perdas internas (PI), perdas totais da máquina (PTM), perdas totais da colheita (PTC) e umidade dos grãos. Os dados foram submetidos ao controle estatístico de processo com a confecção de cartas de controle por variáveis. As perdas naturais foram de 9,26 kg ha-1, totalizando 58,03% das perdas totais na colheita. As perdas da plataforma foram em média 4,22 kg ha-1, representando 62,99% das perdas totais da máquina, que ainda foram compostas pelas perdas internas, com 2,48 kg ha-1, não havendo diferenças entre os tratamentos, ficando abaixo dos limites aceitáveis

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
