Understanding the dynamics of soil organic carbon(SOC) is of fundamental importance in land use and management, whether in the current researches or in future scenarios of agriculture systems considering climate change. In order to evaluate SOC stock of the three districts(Delmiro Gouveia, Pariconha, and Inhapi districts) in the semi-arid region of Brazil in rainfed and irrigated agriculture systems under different climate scenarios using the Century model, we obtained RCP4.5 and RCP8.5 climate scenarios derived from the Eta Regional Climate Model(Eta-Had GEM2-es and Eta-MIROC5) from the National Institute for Space Research, and then input the data of bulk density, p H, soil texture, maximum temperature, minimum temperature, and rainfall into the soil and climate files of the Century model. The results of this study showed that the Eta-Had GEM2-es model was effective in estimating air temperature in the future period. In rainfed agriculture system, SOC stock under the baseline scenario was lower than that under RCP4.5 and RCP8.5 climate scenarios, while in irrigated agriculture system, SOC stock in the almost all climate scenarios(RCP4.5 and RCP8.5) and models(Eta-Had GEM2-es and Eta-MIROC5) will increase by 2100. The results of this study will help producers in the semi-arid region of Brazil adopt specific agriculture systems aimed at mitigating greenhouse gas emissions.

Three-Phase Optimal Power Flow for Study of PV Plant Distributed Impact on Distribution Systems

引用

Journal of Electrical Engineering 2017年第1期5卷 47-56页

作者： Malinwo E. Ayikpa Katia C. de Almeida guilherme C. Danielski GSP-Labspot Department of Electrical Engineering Federal University of Santa Catarina 88040-900 Florianopolis SC Brazil

This paper presents a TOPF （three-phase optimal power flow） model that represents photovoltaic systems. The PV plant is modeled in the TOPF as active and reactive power source. Reactive power can be generated or absorbed using the available capacity and the adjustable power factor of the inverter. The reduction of unbalance voltage and losses in the distribution systems is obtained by actions of reactive power control of the inverter. The TOPF is formulated by current balance equations and the PV systems are modeled via an equivalent circuit. The primal-dual interior point method is used to obtain the optimal operating points for the systems for different scenarios of solar irradiance and temperature, thus providing a detailed view of the impact of photovoltaic distributed generation.

关键词： Three-phase optimal power flow photovoltaic generation unbalance voltage loss primal-dual interior point method.

Endoscopic mucosal resection and endoscopic submucosal dissection in the treatment of sporadic nonampullary duodenal adenomatous polyps

引用

World Journal of Gastrointestinal Endoscopy 2015年第7期7卷 720-727页

作者： Joana Marques Francisco Baldaque-Silva Pedro Pereira Urban Arnelo Naohisa Yahagi guilherme Macedo Faculty of Medicine University of Porto Gastrocentrum Karolinska University Hospital Karolinska Institutet Gastroenterology Department Hospital Sao Joao Department of Clinical Science Intervention and Technology (CLINTEC) Karolinska Institutet and Centre for Digestive Diseases Karolinska University Hospital Division of Research and Development for Minimally Invasive Treatment Cancer Center School of Medicine Keio University

Although uncommon, sporadic nonampullary duodenal adenomas have a growing detection due to the widespread of endoscopy. Endoscopic therapy is being increasingly used for these lesions, since surgery, considered the standard treatment, carries significant morbidity and mortality. However, the knowledge about its risks and benefits is limited, which contributes to the current absence of standardized recommendations. This review aims to discuss the efficacy and safety of endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(esD) in the treatment of these lesions. A literature review was performed, using the Pubmed database with the query: "(duodenum or duodenal)(endoscopy or endoscopic) adenoma resection", in the human species and in English. Of the 189 retrieved articles, and after reading their abstracts, 19 were selected due to their scientific interest. The analysis of their references, led to the inclusion of 23 more articles for their relevance in this subject. The increased use of EMR in the duodenum has shown good results with complete resection rates exceeding 80% and low complication risk(delayed bleeding in less than 12% of the procedures). Although rarely used in the duodenum, esD achieves close to 100% complete resection rates, but is associated with perforation and bleeding risk in up to one third of the cases. Even though literature is insufficient to draw definitive conclusions, studies suggest that EMR and esD are valid options for the treatment of nonampullary adenomas. Thus, strategies to improve these techniques, and consequently increase the effectiveness and safety of the resection of these lesions, should be developed.
