Vital-Fluorochromization of Microorganisms Using 3′,6′-Diacetylfluorescein to Determine Damages of Cell Membranes and Loss of Metabolic Activity by Ozonation

Cell suspensions of Escherichia coli as a model for bacterial populations in wastewaters were treated with ozone as a disinfectant in a continuously operated pilot plant with a plug flow reactor. Suspensions with an initial number of CFU (colony forming units) of 10⁸ mL^?1 were ozonized with ozone concentrations up to 12 mg/L. Metabolic activities and membrane functions break down with increasing ozone concentrations. The fluorochromization using 3′,6′-diacetylfluorescein (FDA) proved to be a suitable method for the detection of an alteration in permeability of the cell membranes and an inactivation of metabolic activity. By fluorescence microscopic and photometric investigations it could be clearly demonstrated that, in the case of disinfection with ozone, inactivation of the cells includes first of all a damage of the cell membranes. In contrast to the determination of the number of CFU, fluorochromization allows the detection of alteration in metabolic activities.     

4，4＇－二苯醚二甲酸改性PET的热性能研究

采用示差扫描量热和热重分析的方法对合成的不同４，４＇－二苯醚二甲酸（ＯＢＢＡ）含量的共聚酯的热性能进行了研究。结果发现共聚酯的熔点和热结晶温度与ＰＥＴ相比有所降低；而冷结晶温度则升高。随着ＯＢＢＡ添加量的增加，在恒温热重分析中热失重速率常数减小；在升温热重分析中，热失重活化能则增加。所有的实验结果皆表明，芳族醚键的引入对提高共聚酯的热性能有重要作用。

Displacement Discontinuity Method for Fracture Mechanics Analysis of Reissner Plates: Static and Dynamic

This paper is concerned with the displacement discontinuity method applied to the shear deformable plates (Reissner’s and Mindlin’s theories) with cracks subjected to static and dynamic loads. Fundamental solutions of dislocation are derived using the Fourier transform method and the Laplace transformation technique. Boundary integral equations are presented in terms of rotations/displacement on the crack surfaces. The Chebyshev polynomials of the second kind are used to evaluate the integral equations with hypersingular kernels on the crack boundaries and determine the stress intensity factors at the crack tips. Comparisons are made with other numerical solutions to demonstrate the proposed method is accurate both for static and dynamic problems.
