To address this issue, our team is now developing an Intelligent Center Pivot (ICP) by integrating sensor-based irrigation scheduling with variable rate irrigation technology. However, before this technology can be applied in commercial production, it is necessary to educate growers about its practicality and potential benefits. The objective of this study was to develop a portable tabletop intelligent center pivot model (ICPDemo) to demonstrate and promote adoption of the ICP technology. This paper describes an ICPDemo constructed in 2014, including the design specifications, electro-mechanical design, control strategy, and performance. The ICPDemo has performed according to design specifications and is successfully being used to demonstrate the benefits and effectiveness of ICP technology for irrigation scheduling.展开更多

"Who to train, how to train people and for whom to train people" is the fundamental problem of education. Moral education is the contemporary answer of our party. "Cultivating socialist builders and successors with all-round development of morality, intelligence, physique, beauty and labor" is the goal and mission of education in the new era. School physical education is a basic project to realize the fundamental task of cultivating people by virtue and improving students' comprehensive quality. It is also an important work to accelerate the modernization of education and build a strong country in education and sports. It has a unique function to carry forward the socialist core values, cultivate students' patriotism, collectivism, socialist spirit and the will to strive for progress and tenacious struggle, and realize sports intelligence and sports heart. The ideological and political education in secondary vocational school physical education should proceed from the characteristics of its own industry and give full play to the moral education function of physical education in secondary vocational health schools.展开更多

文摘Center pivot irrigation systems usually apply a relatively uniform amount of water to fields that are often inherently variable, which could lead to significant waste of water and energy. To address this issue, our team is now developing an Intelligent Center Pivot (ICP) by integrating sensor-based irrigation scheduling with variable rate irrigation technology. However, before this technology can be applied in commercial production, it is necessary to educate growers about its practicality and potential benefits. The objective of this study was to develop a portable tabletop intelligent center pivot model (ICPDemo) to demonstrate and promote adoption of the ICP technology. This paper describes an ICPDemo constructed in 2014, including the design specifications, electro-mechanical design, control strategy, and performance. The ICPDemo has performed according to design specifications and is successfully being used to demonstrate the benefits and effectiveness of ICP technology for irrigation scheduling.

文摘BACKGROUND Thermal damage may lead to inflammation of the peeled mucosal surface during endoscopic submucosal dissection(ESD).AIM To determine the effect of Joule heat on the onset of post-ESD electrocoagulation syndrome(PECS).METHODS In this prospective study,PECS was characterized by in-hospital fever(white blood cell count:≥10000μ/L or body temperature≥37.5℃)and abdominal pain(visual analog scale score≥30 mm during hospitalization or increased by≥20 mm from baseline at admission).High Joule heat was defined as 15390 J.Between April 2020 and April 2024,209 patients underwent colorectal ESD;those with intraoperative perforation or penetration were excluded.The remaining 202 patients were divided into the PECS and non-PECS groups.RESULTS PECS occurred in 30(14.9%)patients.Multivariate analysis revealed high Joule heat as an independent factor associated with PECS(odds ratio=7.96;95%confidence interval:2.91-21.8,P<0.01).The procedure time and presence of lesions in the right colon were not associated with PECS.CONCLUSION Accumulated thermal damage on the peeled mucosal surface should be considered during PECS onset.This thermal damage is likely a major component of the mechanism underlying PECS.
