To overcome large deformation of deep phosphate rock roadways and pillar damage,a new type of constant-resistance large-deformation negative Poisson’s ratio(NPR)bolt that can withstand a high prestress of at least 130 KN was *** the conducted tests,the amount of deformation was 200-2000 mm,the breaking force reached 350 KN,and a high constant-resistance pre-stress was maintained during the deformation process.A stress compensation theory of phosphate rock excavation based on NPR bolts is proposed together with a balance system for bolt compensation of the time-space effect and high NPR *** split-set rock bolts are unable to maintain the stability of roadway roofs and *** verify the support effect of the proposed bolt,field tests were conducted using both the proposed NPR bolts and split-set rock bolts as support systems on the same mining *** addition,the stress compensation mechanism of roadway mining was simulated using the particle flow code in three dimensions(PFC^(3D))-fast Lagrangian analysis of continua(FLAC^(3D))particle-flow coupling numerical ***-site monitoring and numerical simulations showed that the NPR excavation compensation support scheme effectively improves the stress state of the bolts and reduces the deformation of the surrounding *** to the original support scheme,the final deformation of the surrounding rock was reduced by approximately 70%.These results significantly contribute to domestic and foreign research on phosphate-rock NPR compensation support technology,theoretical systems,and engineering practices,and further promote technological innovation in the phosphate rock mining industry.

Analysis of the COVID-19, Outbreak in Brazil Using Topological Weighted Centroid: An Intelligent Geographic Information system Approach

引用

Journal of Data Analysis and Information Processing 2024年第2期12卷 248-266页

作者： Masoud Asadi-Zeydabadi Marina Mizukoshi massimo Buscema Giulia Massini Weldon Lodwick Department of Physics University of Colorado Denver Colorado USA Institute of Mathematics and statistics Federal University of Goi&#225s Goiania Goi&#225s Brazil semeion Research Center Rome Italy Department of Mathematical and statistical sciences University of Colorado Denver Colorado USA

This study used Topological Weighted Centroid (TWC) to analyze the Coronavirus outbreak in Brazil. This analysis only uses latitude and longitude in formation of the capitals with the confirmed cases on May 24, 2020 to illustrate the usefulness of TWC though any date could have been used. There are three types of TWC analyses, each type having five associated algorithms that produce fifteen maps, TWC-Original, TWC-Frequency and TWC-Windowing. We focus on TWC-Original to illustrate our approach. The TWC method without using the transportation information predicts the network for COVID-19 outbreak that matches very well with the main radial transportation routes network in Brazil.

Vulvar Crohn’s disease (VCD) is a rare complication of Crohn’s disease, especially in pediatric population. An early diagnosis can result difficult if the complication does not present in conjunction with the classic gastrointestinal symptoms that characterize this disease. In this study we present the case of a 12-year-old girl whose initial symptom of Crohn’s disease was a symptomatic vulvar swelling promoted by a rectovaginal fistula. We also provide an overview of Crohn’s disease and the vulvar changes found in the course of this disease.

近来的研究表明,由于围术期神经肌肉阻滞管理不当,肌肉松弛药(肌松药)残留阻滞及其术后并发症的发生率居高不下。需要重视神经肌肉功能监测仪、肌松药及其拮抗剂的合理应用,以利于改善神经肌肉阻滞管理。欧洲麻醉和重症监护学会(European society of Anaesthesiology and Intensive Care,EsAIC)首次发布围术期神经肌肉阻滞管理临床指南,旨在为临床医生提供最佳医疗管理的循证建议,以提高围术期患者安全。本指南主要聚焦在3个临床问题:肌松药是否有助于成人气管插管?神经肌肉阻滞深度是否影响腹部手术患者的预后?肌松药残留阻滞的诊断和治疗策略有哪些?根据PICO原则(患者、干预、对照、结局;patient,intervention,comparator,outcome;PICO)构建临床问题并进行文献检索。初始纳入的临床研究为24 000篇,采用逐步筛选策略,最终临床研究88篇纳入指南分析。应用GRADE方法学(Grading of Recommendations,Assessment,Development and Evaluation,GRADE)对结局指标证据、质量等级进行评价。运用两轮德尔菲法收集专家组建议并形成统一推荐:R1推荐应用肌松药辅助气管插管(1A)。R2推荐应用肌松药以减少气管插管导致的咽部和(或)喉部损伤(1C)。R3推荐在快速顺序诱导插管(rapid sequence induction intubation,RsII)时使用短效肌松药,例如琥珀胆碱1 mg/kg或罗库溴铵0.9~1.2 mg/kg(1B)。R4推荐在需要改善外科手术条件时,加深神经肌肉阻滞深度(1B)。R5尚无足够的证据推荐深度神经肌肉阻滞可减轻术后疼痛或降低围术期并发症的发生率(2C)。R6推荐在拇内收肌处刺激尺神经,定量监测神经肌肉阻滞深度以排除肌松药残留阻滞(1B)。R7推荐应用舒更葡糖钠逆转甾体类肌松药(罗库溴铵、维库溴铵)诱导的深、中及浅度神经肌肉阻滞(1A)。R8推荐在使用新斯的明前,TOFr自行恢复至>0.2,并继续定量监测神经肌肉功能,直至TOFr超过0.9(1C)。
