This study sought to elucidate the changes of nuclear factor kappa B （NF-KB） expression and locomotor function of hind limb after subdural injection of BMS-345541 was applied in rats with acute spinal cord injury. The results indicated that BMS-345541 treatment reduced the expression of NF-kB at 24 hours after injury, compared with normal saline-treated rats. This treatment also led to a significant improvement in locomotor functional recovery at 14 days after injury. Overall, the findings demonstrated that BMS-345541 significantly ameliorated spinal cord injury-induced hind limb dysfunction by inhibiting the expression of NF-kB after spinal cord injury.

In most of fault detection algorithms of distributed system, fault model is restricted to fault of process, and link failure is simply masked, or modeled by process failure. Both methods can soon use up system resource and potentially reduce the availability of system. A fault Detection Protocol based on Heartbeat of multiple Master-nodes (DPHM) is proposed, which can immediately and accurately detect and locate faulty links by adopting voting and electing mechanism among master-nodes. Thus, DPHM can effectively improve availability of system. In addition, in contrast with other detection protocols, DPHM reduces greatly the detection cost due to the structure of master-nodes.

In the past years we carried out further stratigraphy division in field and it is found that rich stone artifacts can be found in fluvial-shallow lake-alluvial sediments on the terrace Ⅱ of Biangou River, in Shuidonggou site, Ningxia and they are SDG1, 2 and 7. More luminescence and AMS 14C dating in laboratory show that Paleolithic culture develops during the Upper Paleolithic period with ages of 35―20 ka. The Paleolithic culture of SDG 1 is a little earlier than that of SDG 2 similar to SDG 7. The sandy sediments on terrace Ⅱ of Biangou River deposits in the past 72―18 ka, corresponding to Last Glacial. SDG2 has a stable sedimentary environment, resulting in the continuous stratigraphy, thickest deposits and rich environment and culture information, which can be regarded as the important and classic paleoanthropological section of Late Pleistocene in this region.

Offshore observation platforms are required to have great ability to resist waves when they are operating at sea. Investigation on the motion characteristics of the platforms in the sea can provide significant reference values during the platform design procedure. In this paper, a series of numerical simulation on the interaction of a triple-hulled offshore observation platform with different incident waves is carried out. All of the simulations are implemented utilizing our own solver naoe-FOAM-SJTU, which is based and developed on the open source tools of OpenFOAM. Duration curves of motion characteristics and loads acting on the platform are obtained, and a comparison between the results of the amplitude in different incident waves is presented. The results show that the solver is competent in the simulation of motion response of platforms in waves.

对岩石风化强度反应敏感的化学风化指标是定量评价岩石风化程度的重要参数。评述了包括帕克风化指数(weathering index of Parker,WIP)、风化势能指数(weathering potential index,WPI)、化学蚀变指数(chemical index of alteration,CIA)等12种在以往研究中被认为适合用于岩浆岩风化程度判定的化学风化指标的优点及其局限性。引入了岩石氧化因数X_(o)(X_(o)=Fe_(2)O_(3)/(FeO+Fe_(2)O_(3)))评价火山岩的风化程度,并使用该指标评价了12种化学风化指标在评价超基性岩和基性岩风化中的适用性。在黔西晚二叠世超基性岩和基性玄武岩的实际应用中,将X_(o)≤0.44和X_(o)≤0.55作为超基性岩和基性玄武岩未遭受风化的下限,结合定性分析结果,按风化程度将两种岩石分为新鲜岩石、微风化岩石、中风化岩石、强风化岩石和全风化岩石。X_(o)与12种化学风化指标散点交会的结果显示:BWI、A-FM、LOI这3种指标既适合于风化初期超基性岩和基性玄武岩风化程度的评价,也适合风化中后期超基性岩和基性玄武岩风化程度的评价,其余9种指标仅对风化中后期超基性岩和基性玄武岩的风化程度反应敏感。研究可为超基性岩和基性玄武岩岩质区的工程地质调查与勘察、潜在地质灾害评价、地质灾害隐患防治等提供新思路、新方法,对相似岩质区的岩体风化程度评价研究提供参考。
