Effects of non-thermal plasma treating wheat kernel on the physicochemical properties of wheat flour and the quality of fresh wet noodles

The effects of non-thermal plasma (NTP) on the physicochemical properties of wheat flour and the quality of fresh wet noodles ( FWN) were investigated. The results showed that NTP effectively decreased the total plate count (TPC), yeast and mould count (YMC) and Bacillus spp. in wheat flour. Wet gluten contents and the stability time reached the maximum when treated for 20 s. The viscosity of starch increased significantly after treatment due to the increased of damaged starch. The contents of secondary structure were altered to some extent, which was because that the ordered network structure of gluten protein broken. Furthermore, compared with the control, texture properties of FWN were enhanced significantly at 20 s, and the darkening rate of FWN was greatly inhibited due to the low polyphenol oxidase (PPO) activity. Consequently, the most suitable treatment was 500 W for 20 s, providing a basis for the application of NTP in flour products.

Analysis of failed nuclear plant components

Argonne National Laboratory has conducted analyses of failed components from nuclear power- gener-ating stations since 1974. The considerations involved in working with and analyzing radioactive compo-nents are reviewed here, and the decontamination of these components is discussed. Analyses of four failed components from nuclear plants are then described to illustrate the kinds of failures seen in serv-ice. The failures discussed are (1) intergranular stress- corrosion cracking of core spray injection piping in a boiling water reactor, (2) failure of canopy seal welds in adapter tube assemblies in the control rod drive head of a pressurized water reactor, (3) thermal fatigue of a recirculation pump shaft in a boiling water reactor, and (4) failure of pump seal wear rings by nickel leaching in a boiling water reactor.

湖荡湿地对输水河道磷的截留净化作用

选取太湖流域望虞河沿线的鹅真荡和漕湖两个湖荡湿地分析湖荡湿地对水体中总磷、总溶解磷、颗粒磷以及正磷酸盐的截留净化作用和影响因子。结果表明:①湖荡湿地对输水河道中磷有不同程度的截留净化作用,对颗粒态磷和正磷酸盐的截留净化作用最为显著。②湖荡的面积、空间结构、河水在湖荡输入、输出点的位置以及水生植物分布在一定程度上影响湿地对磷的截留净化作用;③水温、pH、DO浓度和Chl-a浓度与水体中的磷浓度均呈极显著负相关,水温、pH、DO浓度与Chl-a浓度均呈极显著正相关,因此藻类是影响湖荡净化磷的重要因子。

乏燃料溶解器的去污研究

以后处理主工艺流程离线设备——乏燃料溶解器作为去污对象，采用FL-AP去污工艺，经4步去污后，去污效果达到了去污要求（α污染水平≤4Bq/cm^-2，β污染水平≤40Bq/cm^-2）。该去污工艺对α、β的一步平均去污系数分别为2.2和2.4。溶解器解体检测结果表明，乏燃料溶解器的内表面沾污呈现不均匀分布。将挂片法和解体检测的结果以及FL-AP工艺去污废液的放射性测量结果相结合，可较确切地估算溶解器内表面去污前的放射性污染水平。     

Reprint of: Novel approach to decontaminate food-packaging from pathogens in non-thermal and not chemical way: Chlorophyllin-based photosensitization

This study was focused on the possibility to inactivate main food pathogens, their spores and biofilms on the surface of packaging material polyolefine by Na-chlorophyllin (Na-Chl)-based photosensitization and to compare efficiency of this treatment with conventional antimicrobials.
