西秦岭西段早―中三叠世隆务河群沉积相浅析  [PDF]
魏立勇
地质与勘探 , 2014,
Abstract: 区内中―下三叠统隆务河群(T1-2L)属巨厚复理石相,显示出以浊流为主的深海沉积特征;通过沉积相分析,整个隆务河群由下而上呈一个明显的变细、变薄的序列,呈一个较完整的海底扇退积型沉积序列。

电子与信息学报 , 2010,
Abstract: The existing fault-tolerant scheduling algorithms are mainly based on primary/backup copies technology and the utilization of processor decreases greatly with the number of faults increases.In this paper,a real-time fault-tolerant scheduling algorithm is proposed to schedule periodic and aperiodic tasks jointly and tolerate multiple processor faults.The DS(Deferrable Server) algorithm is extended to the multiprocessors system,and several deferrable servers can be set to schedule aperiodic tasks.The faults c...

Abstract: Proposes a structural model of embedded isomerous multi-processor system, and describes the mechanism of communication of such system. Furthermore, in the case that a signal processing device on TMS320C6416 DSP from TI is used as processing node, in the real-time image processing system based on such embedded isomerous multi-processor system model, a new method of high-speed data transmission between the processing node and the host control node is proposed, by which the data transmission speed is greatly improved.

Abstract: 通用高性能计算机需求不断增加,传统多处理系统得到了快速发展,但其成本和功耗也大幅攀升,以嵌入式系统构成群集替代传统平台成为未来焦点。讨论了一种成本低廉的嵌入式多处理器系统的基本结构与实现,利用平台特性实现了一种特殊MIMD结构,在集中式工作池的基础上能够支持混合调度机制以适应不同工作环境、任务条件需要。试验结果分析表明,该系统能够支持多种调度机制的混合调度策略,更能够较大幅度提升系统的运算能力。
Generic multi-processor systems in high performance computing applications such as Intel, NVIDIA Tesla systems have been developing rapidly, but their cost and power consumption were soaring;low-end hardware, especially in embedded systems that make up the cluster as an alternative to traditional platforms got attention and rapid development. We discuss a low cost infrastructure and implementation of embedded multiprocessor systems, take advantage of platform features to implement a special MIMD structure,which is capable of supporting a hybrid scheduling system adaptable to different working environments, tasks, and conditions. Test results and their analysis show preliminarily that the system can support a variety of hybrid scheduling policy for scheduling and can significantly improve the processing power of the system
Urethral duplication.

Acta Medica Okayama , 2003,
Abstract: Urethral duplication is a rare congenital anomaly. Although a number of theories have been proposed to describe the embryology of the condition, the actual mechanism of the disorder is still unclear. We report here a case of urethral duplication in a 11-year-old boy complaining of a double stream, and review the current literature on this rare entity.

Abstract: 目的?开展医院科务公开督查工作,了解全院各科室科务公开工作进展情况,收集员工最在意的问题。方法?2013年11月-12月采用问卷调查为主,结合参与科室各种会议、访谈科室员工、查阅文档资料等其他方式开展督查。结果?科务公开度为(78.39±18.55)%。其中公开较好的科务为政策类科务(>85%),公开度得分较低(<75%)且员工反映较集中的科务为科研及学术任职类、财务收支及酬金分配类、人事安排和培养类科务。结论?科室足够重视、关注员工重视的问题、合理利用公开方式、有力监督和充分利用监督结果是提升科务公开度的有效举措。
Pyloroduodenal Duplication Cyst: The Rarest Alimentary Tract Duplication  [cached]

APSP Journal of Case Reports , 2012,
Abstract: Pyloroduodenal duplication is the rarest alimentary tract duplication known so far. A 1-year-old female patient presented with abdominal pain, lump in the epigastrium and occasional vomiting. On ultrasound and CT scan of abdomen suspicion of duplication cyst was made. Operation revealed a duplication cyst along pylorus and first part of the duodenum. Excision of free part and mucosal stripping of the attached part of the duplication was done.

Rectal duplication.  [cached]

Journal of Postgraduate Medicine , 1995,
Abstract: Duplications of the alimentary tract are of a great rarity, particularly so in the rectum. Because of its rarity, the difficulty of making a correct diagnosis and of selection of proper approach for treatment, this entity bears a special significance. The present case report deals with a female newborn who presented with imperforate anus and a rectovestibular fistula and a mass prolapsing at the introitus. Complete excision of the mass was carried out through the perineal approach and the child then underwent, a PSARP for the correction of the rectal anomaly. Histology confirmed the mass to be a rectal duplication.

Abstract: Duplication of the gallbladder has been reported as an extremly rare congenital anomaly of the hepatobiliary system resulting fromabnormalities in embryogenesis during the fifth and sixth weeks of gestation, with an incidence of 1 in 3800-4000 autopsies. Duplicate gallbladder and its variable anatomy was first described byBoyden in 1926 and there are approximately 210 published cases to date. Variations include duplicate, triplicate and septated gallbladder. This anomaly is important in clinical practicebecause it may cause some clinical, surgical and diagnostic problems, and is important for surgeons because of associated anatomical variations of main bile duct and hepatic artery andincreased risk of common bile duct injury. Ultrasound is the preferred modality of imaging. Several entities may mimic a double gallbladder including a folded gallbladder, choledocal cyst,phrygian cap, pericholecystic fluid, gallbladder diverticulum, vascular band across the gallbladder and focal adenomyomatosis. Laparoscopic cholecistectomy has become a standard operation forthe great majority of benign gallbladder diseases including congenital anomalies of the biliary tree and the gallbladder. We present a case of duplicated gallbladder of 8 years old girl pacient who presented with recurrent upper abdominal pain and diagnosed intraoperatively with double gallbladder and treated during open surgery – cholecystectomy of duplicated gallbladder.
