“体验”与“改造”--现代中国文艺功能观念的早期建构

文艺功能观念不仅关乎“文艺是什么”的本质探究,还广泛涉及文艺与世界、社会、人生的关系之思,并最终指向“文艺能够做什么”的现实命题。现代中国文艺功能观念的早期建构主要表现为“体验”与“改造”两种倾向,“体验”功能倾向蕴含以个体为观照对象的情感体验倾向和以整体为观照对象的生命体验倾向,“改造”功能倾向则包含以外在实践为宗旨的社会改造倾向和以内在实践为宗旨的人生改造倾向。正是基于对改造社会、美化人生的现实需求,“体验”与“改造”两者相辅相成,共同推动现代中国文艺功能观念的建构进程。

Analysis of semi-solid response under rapid compression tests using multi-scale modelling and experiments

Simulating semi-solid metal forming requires modelling semi-solid behaviour.However, such modelling is difficult because semi-solid behavior is thixotropic and depends on the liquid-solid spatial distribution within the material.In order to better understand and model relationships between microstructure and behavior, a model based on micromechanical approaches and homogenisation techniques is presented.This model is an extension of a previous model established in a pure viscoplastic framework to account for elasticity.Indeed, experimental load-displacement signals reveal the presence of an elastic-type response in the earlier stages of deformation when semi-solids are loaded under rapid compression.This elastic feature of the behaviour is attributed to the response of the porous solid skeleton saturated by incompressible liquid.A good quantitative agreement is found between the elastic-viscoplastic predicted response and the experimental data.More precisely, the strong initial rising part of the load-displacement curve, the peak load and the subsequent fall in load are well captured.The effect of solid fraction on mechanical response is in qualitative agreement with experiments.

Estimating glomerular filtration rate preoperatively for patients undergoing hepatectomy

AIM:To compare creatinine clearance(Ccr) with estimated glomerular filtration rate(eGFR) in preoperative renal function tests in patients undergoing hepatectomy.METHODS:The records of 197 patients undergoing hepatectomy between August 2006 and August 2008 were studied,and preoperative Ccr,a three-variable equation for eGFR(eGFR3) and a five-variable equation for eGFR(eGFR5) were calculated.Abnormal values were defined as Ccr < 50 mL/min,eGFR3 and eGFR5 < 60 mL/min per 1.73 m2.The maximum increases in the postoperative serum creatinine(post Cr) level and postoperative rate of increase in the serum Cr level(post Cr rate) were compared.RESULTS:There were 37 patients(18.8%) with abnormal Ccr,31(15.7%) with abnormal eGFR3,and 40(20.3%) with abnormal eGFR5.Although there were no significant differences in the post Cr rate between patients with normal and abnormal Ccr,eGFR3 and eGFR5 values,the post Cr level was significantly higher in patients with eGFR3 and eGFR5 abnormality than in normal patients(P < 0.0001).Post Cr level tended to be higher in patients with Ccr abnormality(P = 0.0936 and P = 0.0875,respectively).CONCLUSION:eGFR5 and the simpler eGFR3,rather than Ccr,are recommended as a preoperative renal function test in patients undergoing hepatectomy.

In Vitro Study on Virulence Potentials of Burkholderia pseudomallei Isolated from Immunocompromised Patients

Eighty four throat swabs were obtained from Basrah General Hospital inpatients （N = 34）： 17 were suffering from renal failure and the other 17 were diabetics; and from outpatients （N = 50）. Throat swabs were cultured first in the selective media Ashdown＇s broth then subcultured on Ashdown＇s agar to isolate Burkholderia pseudomallei which was recovered from seven cases （8.33%）. Four isolates were from renal failure patients （23.53%）, two from diabetic patients （11.76%） and the seventh isolate was from an outpatient with tonsillitis. All isolates were able to produce capsules, form filament chains, exhibit swarming motility and were arabinose non assimilators （Ara-） indicative of their virulence. Additionally, isolated B. pseudomallei were found to produce protease, lipase, hemolysin, and lecithinase and were able to produce biofilm, the root of many troublesome persistent infections that resist antibiotic treatment. Susceptibility of the seven isolates of B. pseudomallei toward 11 antibiotics was assessed, isolates were found multiply resistant to all antibiotics apart from ciproflaxin. This study confirms for the first time isolation of B. pseudomallei from immunocompromised patients in Basrah city of Iraq and describes their virulence potentials.

Test Bench for Robotics and Autonomy： Overview and Test Results

In this paper, the TAS-I （Thales Alenia Space-Italy） Test Bench for Robotics and Autonomy （TBRA） is presented. It is based on a flexible and modular software architecture （Framework Engine）, in which each functional module （representing the GNC subsystems） implements a key functionality of the GNC （Guidance Navigation and Control）. Modules communicate by means of standardised interfaces designed for exchange of necessary information among the modules composing the entire system. This approach permits the interchange-ability of each subsystem without affecting the overall functionalities of the GNC system. In this paper, the TBRA system, together with the implemented functional modules will be described. Tests results will be reported and future development will be discussed.

To introduce the experience of professor JIA Chun-sheng in rapid analgesia and motor function rehabilitation by subcutaneous penetration needling of auricular acupuncture.Subcutaneous penetration needling of auricular acupuncture plays a role in rapid analgesia and motor function rehabilitation in treatment of pain in limbs and trunk and/or limb dysfunction caused by migraine,cervical spondylosis,acute lumbar sprain,soft tissue injury,scapulohumeral periarthritis,lumbar disc herniation,sciatica,stroke or cerebral trauma,and it is worthy of being widely promoted and applied clinically.

A New Cooperation Mechanism of Kinesin Motors when Extracting Membrane Tube

Membrane tubes are important functional elements for riving cells. Experiments have found that membrane tubes can be extracted from giant lipid vesicles by groups of kinesin. How these motors cooperate in extracting the membrane tube is a very important issue but still unclear so far. In this paper, we propose a cooperation mechanism called two-track-dumbbell model, in which kinesin is regarded as a dumbbell with an end （tail domain） tethered on the fluid-like membrane and the other end （head domain） stepping on the microtubule. Taking account of the elasticity of kinesin molecule and the excluded volume effect of both the head domain and the tail domain of kinesin, which are not considered in previous models, we simulate the growth process of the membrane tube pulled by kinesin motors. Our results indicate that in the case of strong or moderate exclusion of motor tails, the average number of motors pulling the tube can be as high as 9 and thus motors moving along a single microtubule protofilament can generate enough force to extract membrane tubes from vesicles. This result is different from previous studies and may be tested by future experiments.
