1运动方向的线状指示物与斑变晶中叶理交切轴(FIAs)的比较及其与板块相对运动方向的关系(英文)显示文摘过去还无人指出过板块相对运动的方向与缓倾斜叶理、逆断层和断层上的线状指示物有直接关系,这是因为缓倾斜构造上的运动方向只和变厚了的造山地层的重力塌陷有关,它们和俯冲板块传递给仰冲板块的推力没有关系。缓倾斜叶理上的运动方向的线状指示物和斑状变晶中的叶理弯曲或叶理交切轴(FIA)并无直接关系,这是因为FIA的指向受缓倾斜叶理和斑状变晶边缘上产生的、近乎垂直的叶理之间的交切面控制。在班状变晶边缘上形成的、近乎垂直的叶理在基质中的方位可能在较大范围内变动,因为它们会在稍早期间形成的叶理再活化作用影响下发生转动或遭到破坏。斑状变晶边缘上近乎垂直的叶理,与形成于早期或晚期的缓倾斜叶理的交线,在后期的生长中被圈闭在班状变晶里,此交线规定出了FIA的方位,而与叶理上的运动方向无关。从美国佛蒙特州阿巴拉契亚山脉采集的FIA资料指出,在125km×35km的一片地区内,在该地岩层所发生的多次变形中,从未曾使早期形成的FIA组的方位发生变动。这种情况要求:后来的每一代褶皱都是由于渐进的。总体不均匀缩短作用造成的。这种情况表明:FIA保存着原始的运动方向,此方向未因以后的变形而转动。Tim H.

2Performance of tacrolimus in hospitalized patients with steroid-refractory acute severe ulcerative colitis显示文摘BACKGROUND Acute severe ulcerative colitis unresponsive to systemic steroid treatment is a lifethreatening medical condition requiring hospitalization and often colectomy.Despite the increasing choice of medical therapy options for ulcerative colitis, the condition remains a great challenge in the field of inflammatory bowel diseases(IBD). The performance of the calcineurin inhibitor tacrolimus in this clinical setting is insufficiently elucidated.AIM To evaluate the short and long-term outcomes of tacrolimus therapy in adult inpatients with steroid-refractory acute severe ulcerative colitis.METHODS We conducted a retrospective monocentric study enrolling 22 patients at a tertiary care center for the treatment of IBD. All patients who were admitted to one of the wards of the Department of Gastroenterology and Hepatology of the Heidelberg University Hospital with acute severe ulcerative colitis between 2007 and 2018, and who received oral or intravenous tacrolimus for steroid-refractory disease were included. Baseline characteristics and data on the disease courses were retrieved from entirely computerized patient charts. The primary study endpoint was clinical response to tacrolimus therapy, resulting in discharge from the hospital. Secondary study endpoints were colectomy rate and time to colectomy, achievement of clinical remission under tacrolimus therapy, and the occurrence of side effects.RESULTSIn the majority of the 22 included patients(68.2%), tacrolimus therapy was initiated intravenously and subsequently converted to oral administration. The treatment duration was 128 ± 28.5 d(mean ± SEM), and the patients were followed up for 705 ± 110 d after treatment initiation. Among all patients, 86.4%were discharged from the hospital under continued oral tacrolimus therapy. In36.4% of the patients, the administration of tacrolimus resulted in clinical remission at some point during the treatment. Thirty-two percent of the patients underwent colectomy between 5 and 194 d after the initiation of tacrolimus treatment(mean: 97.4 ± 20.8 d). Colectomy-free survival rates at 1, 3, 6 and 12 mo after the initiation of tacrolimus therapy were 90.9%, 86.4%, 77.3% and 68.2%,respectively. The safety profile of tacrolimus was overall favorable. Only two patients discontinued the treatment due to side effects.CONCLUSION The short-term outcome of tacrolimus in steroid-refractory acute severe ulcerative colitis was beneficial, and side effects were rare. In all, tacrolimus therapy appears to be a viable option for short-term treatment of steroidrefractory acute severe ulcerative colitis besides ciclosporin and anti-tumor necrosis factor α treatment.Peter Hoffmann Cyrill Wehling Johannes Krisam Jan Pfeiffenberger Nina Belling Annika Gauss Department of 2019World Journal of Gastroenterology2019,25,13:2

5Analysis and Simulation for Capacity of Time Division-Synchronous Code Division Multiple Access System显示文摘Capacity both in uplink and downlink of TD-SCDMA (time division-synchronous code division multiple access)system is studied in a multi-cell environment. The theoretical expressions of the mean of intercell interference in uplinkand the mean of sum of power allocation in downlink are given, by which uplink and downlink capacity is analyzed.Furthermore, we give the simulation models for both uplink and downlink capacity. The results from theoretical analysisand simulation fit very well. In the end, the maximum number of users that TD-SCDMA system can serve for 12.2kspeech service is given.Sun Chengjun, Zhang Zhongzhao, Ba Yong2 & Cao Pengzhi (Communication Research ('enter, Harbin Institute of Technology, Harbin 150001, P.

8旧梦新生 纽约肯尼迪机场TWA酒店显示文摘建于20世纪60年代、由沙里宁设计的美国纽约肯尼迪机场第五航站楼一度是这里的地标性建筑。建筑师的设计方案打破了当时世人对混凝土材料过于厚重、死板的固有印象。工程采用特殊的手法,浇筑出轻盈的航站楼主体,建成后的航站楼如同一只大鸟,时刻准备振翅高飞。极具雕塑感的外形,柔美又不失力道的曲线,充满想象力的内部空间,这些元素都曾经让无数乘客体会到建筑艺术无与伦比的魅力。然而随着时代的发展,该航站楼已经不能适应肯尼迪机场巨大的吞吐量,再加上环球航空公司因为经营不善导致的一系列问题,最终使得TWA航站楼被迫关闭。 苏西(编译) Beyer Blinder Belle Architects Planners,INC Architecture Design,Turner Construction Company Courtesy of Stonehill Taylor(摄影) 2020室内设计与装修2020,,9:1

16A Numerical Tele-service System and its Realization on a PC-PLC Network显示文摘Modern telecommunication methods have many impacts on manufacturing, and tele service has become one of the strategic approaches to realize the ideas of a flexible manufacturing system. Monitoring and maintenance of production lines from the remote monitor center is an important application of such techniques. This paper presents a typical model of tele service systems and discusses the underlying challenges. RMMST (remote monitoring and maintenance system testbed), based on PC PLC and their networks which are used widely in production lines, is presented in detail as a concrete example. With the support of digital technique, RMMST can be used in the monitoring and maintenance of remote production lines conveniently.YUAN Chi 1, LU Tian sheng 1, GU Xing cai 2, SONG Li bo 1 1 School of Mechanical Engineering, Shanghai Jiaotong University, Shanghai 200030, P.R.China 2 Shanghai Bell Company Ltd., Shanghai 201206, P.R.China 2002International Journal of Plant Engineering and Management2002,7,1:0
