Cultivation of “Roxo de Valinhos” Fig Tree in Different Plant Densities for Production of Green Figs for Industry in the Region of Campo Das Vertentes-MG

引用

Agricultural Sciences 2018年第9期9卷 1097-1106页

作者： Paulo Márcio Norberto Angelo Albérico Alvarenga JoséClelio de Andrade filipe Almendagna Rodrigues Lair Victor Pereira Emerson Dias Goncalves Company of Farming Research of Minas Gerais—EPAMIG LavrasBrazil Federal University of Lavras—UFLA LavrasBrazil

The objective of this work was to study the effect of different planting densities on the development and production of “Roxo de Valinhos” green figs for industry, in the Campo das Vertentes-MG region. The experiment was installed at the Risoleta Neves Experimental Field—CERN/EPAMIG. The plants used were three years old and were arranged in three randomized blocks, subject to three different planting densities, with spacings ranging from 1 m (4000 plants·ha-1), 1.5 m (2666 plants·ha-1), and 2 m (2000 plants·ha-1) between plants in the planting line and 2.5 m between row for all planting densities. The average length of the branches (m), average number of fruits per branch, average number of fruits per plant, average weight of fruits, average yield per plant and the average yield per hectare (kg) were evaluated. It was verified that, there were no significant differences in the length of branch and in the average weight of fruit, in the three densities of fig tree planting. (4000 plants·ha-1), the average number of fruits per branch (7.5), per plant (55.87) and yield per plant (878.93 kg) were lower, however. The average yield per hectare (3515.73 kg) was higher than in other growing densities. It is concluded that, the higher density of plants (4000 plants·ha-1), provides the highest productivity per area, without damages to the quality of the fruits.

Adenocarcinoma of the third and fourth portions of the duodenum: The capsule endoscopy value

引用

World Journal of Gastroenterology 2015年第31期21卷 9437-9441页

作者： Feliciano Chanana Paquissi Ana Henriqueta filipe Bunga Pimentel Lima Maria de Fátima do Nascimento Vieira Lopes Francisco Viamontes Diaz Department of Medicine Clínica GirassolLuanda 1215Angola Service of Clinical Pathology Clínica GirassolLuanda 1215Angola Service of Gastroenterology Clínica GirassolLuanda 1215Angola Department of General Surgery Clínica GirassolLuanda 1215Angola

Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However,its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions,emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man,40 years old,with no medical history,with abdominal discomfort and progressive fatigue,presented four months ago with one episode o f m o d e ra t e m e l e n a. T h e p hy s i c a l e x a m i n a t i o n was normal,except for mucosal pallor. Blood tests were consistent with microcytic,hypochromic iron deficiency anemia with 7.8 g/d L hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions o f t h e d u o d e n u m. B i o p s y s h o w e d a m o d e ra t e l y differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum,without distant metastasis. The patient underwent segmental resection(distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis,with transmural infiltration,without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value.

本文报道了伊帕廷加的米纳斯钢铁公司170t转炉应用后搅技术的结果。试验基本上由氧气吹炼结束后通过喷吹氩气使金属熔池搅拌组成，收集后搅期间前后大约2min的钢水化学分析、熔池温度及其氧含量结果。结果表明在喷吹气体时期中，钢水中的磷、氧和碳含量均呈现下降趋势，而且出钢前各成分减少的结果存在不同差异，证明后搅技术在优化工艺中有效，这些结果也证实后搅影响了脱磷和脱氧反应平衡条件的方法。该工艺的优点是为减少脱氧材料消耗提供了大量机会，因此降低了生产成本，提高了钢水洁净度。同时探讨了后搅过程中脱磷和脱氧反应的相关机理。

The adipose body of cheek is the tissue located in the buccal space. In the past, the partial removal of this tissue, called jugal lipectomy, was indicated to fill defects resulting from buccosinusal communications and/or maxillary resections. Recently, such technique became popular in facial aesthetics as it gives patients the feel of a more delicate face, in which the zygomatic bone appears to be more prominent due to the reduction in the volume of the cheeks. However, many professionals are unaware of how to establish the correct diagnosis of facial volume alterations, as well as in performing and treating the complications that may arise from jugal lipectomy. The aim of this paper is to present three clinical cases with different applications of jugal lipectomy, discussing some relevant aspects of surgical planning that involve the request for imaging exams and a previous study of this tissue's anatomical features.
