Researchers from the National Institute for Occupational Safety and Health(NIOSH)are developing a coal pillar rib rating(CPRR)technique to measure the integrity of coal *** CPRR characterizes the rib composition and evaluates its impact on the inherent stability of the coal *** CPRR utilizes four parameters:rib homogeneity,bedding condition,face cleat orientation with respect to entry direction,and rib *** these parameters are measurable in the field.A rib data collecting procedure and a simple sheet to calculate the CPRR were *** developed CPRR can be used as a rib quality mapping tool in underground coal mines and to determine the potential of local rib instabilities and support requirements associated with overburden *** calculations were conducted for 22 surveyed solid coal ribs,mainly composed of coal *** on this study,the rib performance was classified into four categories.A preliminary minimum primary rib support density(PRSD)line was obtained from these surveyed *** sample cases are presented that illustrate the data collection form and CPRR calculations.

开发烷基技术生产各种化学中间体尽管会遇到很多困难,但开发烷基技术正在成为热点。要对烷基活化技术的发展作出准确的预测并不是一件容易的事,但发展烷基技术却是一种必然。由于全球部分地方天然气资源非常充足,化工技术开发人员希望找到一种使用烷烃直接生产化学中间体的工艺路线,而无需像以前工艺一样进行裂化或脱氢作用得到烯烃。

美国放射学院(American College of Radiology,ACR)偶发病变委员会(Incidental Findings Committee,IFC)发布了CT或MR偶发胰腺囊肿的管理建议。该建议是对美国放射学院杂志(JACR)2010年发布的肾上腺、肾脏、肝脏以及胰腺偶发病变管理白皮书中胰腺部分的更新。该管理方案由多位腹部影像医师、1位胃肠道学医师以及1位胰腺外科医师所组成的胰腺亚组委员会制定。该方案参考已发表的文献和专家意见,经反复协商,最终达成共识。该方案的分支成功地根据患者的临床特点及影像特征将胰腺囊肿进行分类,评估终点为良性和/或进展缓慢病变的诊断(足以结束随访)或具体的管理建议。该方案适用于大多数但非全部的病理及临床情况。该方案旨在通过提供胰腺偶发囊肿的管理指导,来提高患者的管理质量。
