KERFIX, a time-series station in the Southern Ocean: a presentation

Between January 1990 and March 1995, the research project KERFIX undertook the first regular noncoastal multiyear acquisition of parameters related to the carbon cycle in the Southern Ocean at a time series station located at 50°40′ S–68°25′ E, 60 miles southwest of the Kerguelen Islands. The objectives of KERFIX are (1) to monitor the ocean/atmosphere CO₂ and O₂ exchanges and to understand which processes govern these exchanges (2) to observe and interpret the seasonal and interannual variability of the production, flux, decomposition and dissolution of carbon and associated elements at this location. In addition, micropaleontological studies describe the present and past flux dynamics in this oceanic area, to improve the knowledge of the transfer functions of some oceanographic proxies. This paper presents a survey of the KERFIX program: scientific objectives, organization of the field operations and some main results obtained since the beginning of KERFIX program, as well as the results of the temporal evolution of hydrological, chemical and biological parameters.

The Variable Linear Transmission for Regenerative Damping in Vehicle Suspension Control

This paper introduces the concept of regenerative damping in vibration control, die storage of energy normally dissipated by a passive viscous damper. A device, the Variable Linear Transmission, is proposed to accomplish this task. Analysis of die proposed device as a damper in a typical passenger vehicle is conducted for die cases in which the device's active component operates ideally and with activation dynamics included. Results indicate that regenerative vibration control is feasible and can provide damping nearly identical to that of a passive viscous damper while storing the damped energy.     

HBV-TF抗原特异性的研究

应用抗原特异性玫瑰花结试验对比研究HBV-TF、N-TF及TMP的生物活性及抗原特异性。实验发现经HBV-TF作用的绵羊淋巴细胞与HBsAg包被的绵羊红血球形成的抗原特异性玫瑰花结阳性率最高,为4.5%,而经N-TF及TMP作用的绵羊淋巴细胞仅形成极少的玫瑰花结,分别为0.35%和0.33%与HBV-TF作用组相比有非常显著的差异(P<0.01)。
