摘要： In order to evaluate the roles of the vestibular system in controlling arterial pressure (AP) during exposure to a short period of microgravity (mu G), the AP was measured in conscious free-moving rats having intact vestibular systems and those having vestibular lesions (FM-Intact and FM-VL groups, respectively). During free drop-induced mu G, the AP increased in the FM-Intact group;it was 38 +/- 4 mmHg more than the AP observed during I G. However, the increase in AP was significantly lower in the FM-VL group (20 2 mmHg). Further, to examine the sudden effect of a body floating in the midair in response to the AP during exposure to mu G a body stabilizer was placed on the back of rats having intact vestibular systems and those having vestibular lesions (STAB-Intact and STAB-VL groups, respectively). The increase in the AP was significantly depressed in the STAB-Intact group;when compared with that in the FM-Intact group, but the increase was still significant (27 +/- 2 mmHg). On the other hand, the increase in the AP was completely eliminated in the STAB-VL group (7 +/- 5 mmHg). These results indicate that the AP increases during exposure to mu G in conscious rats, and the vestibular system and body stability are significantly involved in this response.

摘要： “焚书令”字里行间体现出来的是一种精密的专制主义知识分类体系。在它所包括的政治法律、历史典籍、人文价值和实用技术这四种知识中,前三种皆属于意识形态知识范畴,也可以视为广义的价值知识。这说明,“焚书令”所依托的是一个价值理性和工具理性都同样发达的意识形态秩序。正因为价值理性发达,所以它能对区分各种价值知识制定出明确的判断标准;正因为工具理性发达,所以它能对控制各种价值知识制定出严格的操作规则。

摘要： 本论文对在不同环境下抑制混凝土碱骨料反应的措施进行了一系列调查研究，同时还研究了混凝土的特性、操作方法、抑制效果、以及通过社会成本体现对环境的影响。提出了具有环境意识的控制碱骨料反应的设计理念，而且开发了一种相应的计算机辅助设计系统。该系统可以帮助设计者选择一种有效控制碱骨料反应的措施。根据特定的条件（例如：环境条件、活性骨料的特性等）对新混凝土及旧混凝土给出有效地控制碱骨料反应的措施，同时也给出了这些措施的操作性、成本及其社会成本。本文详细介绍了这种控制碱骨料反应措施的设计理念及计算机辅助设计系统，同时列举了一个控制混凝土中碱骨料反应的应用实例。

摘要： Ramchandra, Rohit, Carolyn J. Barrett, Sarah-Jane Guild, and Simon C. Malpas. Evidence of differential control of renal and lumbar sympathetic nerve activity in conscious rabbits. Am J Physiol Regul Integr Comp Physiol 290: R701-R708, 2006. First published October 20, 2005;doi:10.1152/ajpregu.00504.2005.-We have explored the possibility that renal sympathetic nerve activity (RSNA) and vasomotor sympathetic nerve activity are differentially regulated. We measured sympathetic nerve activity (SNA) to the kidney and the hind limb vasculature in seven conscious rabbits 6-8 days after the implantation of recording electrodes. Acute infusion of N-G-nitro-Larginine methyl ester (L-NAME) (6 mg (.) kg(-1) (.) min(-1) for 5 min) led to an increase in blood pressure ( from 66 +/- 1 to 82 +/- 3 mmHg) and a decrease in heart rate (from 214 +/- 15 to 160 +/- 13 bpm). L-NAME administration caused a significantly greater decrease in RSNA than lumbar sympathetic nerve activity (LSNA) ( to 68 +/- 14% vs. 84 +/- 4% of control values, respectively). Volume expansion (1.5 ml (.) kg(-1) (.) min(-1)) resulted in a significant decrease in RSNA to 66 +/- 7% of control levels but no change in LSNA ( 127 +/- 20%). There was no difference in the gain of the baroreflex curves between the LSNA and RSNA [maximum gain of -7.6 +/- 0.4 normalized units (nu)/ mmHg for LSNA vs. -7.9 +/- 0.75 nu/mmHg for RSNA]. A hypoxic stimulus (10% O-2 and 3% CO2) led to identical increases in both RSNA and LSNA ( 195 +/- 40% and 158 +/- 21% of control values, respectively). Our results indicate tailored differential control of RSNA and LSNA in response to acute stimuli.

摘要： 钢琴学习应该是对钢琴技术和思维意识控制的综合培养,其中思维意识控制的训练更为重要。一般而言,钢琴学习中思维意识控制能力的发展要经历四个阶段。而在思维能力中,注意力无疑是弹奏控制的核心问题,能否用思维意识合理调整好注意力决定着弹奏的成败。

摘要： The aim of the present study was to assess several biochemical and physiological endpoint parameters alongside controlled hemorrhagic and recovery phases of chronically instrumented, conscious and unrestrained healthy rats. Male Sprague-Dawley rats (12-14weeks;430 +/- 20g;n=2218) were instrumented with a saline-perfused femoral arterial catheter and placed individually in a metabolic cage for up to 20 days, allowing instant assessments of the hemodynamic profile and blood and urine sampling for hematological profile and biochemical measurements to assess hepatic, renal and metabolic functions. In addition, body weight, food and water intake, and diuresis were monitored daily. After a 7-day stabilization period, the rats underwent severe and acute hemorrhagic shock (HS) (removal of 50% of total circulating blood volume), kept in hypovolemic shock for an ischemic period of 50 min and then resuscitated over 10 min. Gr. I was re-infused with autologous shed blood (AB;n = 10) whereas Gr. 2 was infused 1:1 with a solution of sterile saline-albumin (SA;7% w/v) (n =8-12). Ischemic rats recovered much more rapidly following AB re-infusion than those receiving SA. Normal hemodynamic and biochemical profiles were re-established after 24 It. Depressed blood pressure lasted 4-5 days in SA rats. The hematological profile in the SA resuscitated rats was even more drastically affected. Circulating plasma concentrations of hemoglobin (-40%), hematocrit (-50%), RBC (-40%) and platelets (- 41%) counts were still severely decreased 24 h after the acute ischemic event whereas WBC counts increased 2.2-fold by day 4. It took 5 - 9 days for these profiles to normalize after ischemia-reperfusion with SA. Diuresis increased in both groups (by 45 7% on day 1) but presented distinct electrolytic profiles. Hepatic and renal functions were normal in AB rats whereas altered in SA rats. The present set of experiments enabled us to validate a model of HS in conscious rats and the use of an integrat
