N-糖基化引起葡萄糖淀粉酶不同型的差异

红曲霉葡萄糖淀粉酶具有多型性,在聚丙烯酰胺凝胶电泳(PAGE)上有5条蛋白带(E_1——E_5) E_3,E_4,和E_5均为糖蛋白,含糖量分别为7%和9%.用ConA-Sephafose分高纯化红曲霉葡萄糖淀粉酶时,被α-甲基D-葡萄糖苷依亲和力由小到大的顺序将E_3,E_4和E_5洗脱下来,也说明他们的含糖量E_5>E_4>E_3.糖肽之间的连结方式除O-糖苷键外,还有N-糖苷键、我们试图用内切或外切糖昔酶切去糖链,以查明糖基化对多型性的影响.

Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.     

Modeling and Control of Active Suspensions for MDOF Vehicle

The conventional method for analyzing active suspension control for a vehicle is only to analyze a quarter or half car with a lower order degree-of-freedom (DOF) model, but such models do not actually model practical applications. Accurate models of a suspension control system require a multi-degree-of-freedom (MDOF) vehicle model with a detailed model of the controller. An MDOF model was developed including the influence of factors such as the engine, the seats, and the passengers to describe vehicle motion using a reduced order model of the controller designed by using the H∞ control method. The control system performance has been investigated by comparing the H∞controller with a linear quadratic (LQ) controller.
