China is one of the largest meat producing countries in the wodd. With the growing concern for food safety more attention has been paid to meat quality. The application of conventional test methods for meat quality is limited by many factors, and subjectiveness, such as longer time to prepare samples and to test. A sensor matrix was constructed with several separate air sensors, and tests were conducted to detect the freshness of the beef. The results show that the air sensors TGS2610, TGS2600, TGS2611, TGS2620 and TGS2602 made by Tianjin Figaro Electronic Co, Ltd could be used to determine the degree of freshness but TGS2442 is not suitable. This study provides a foundation for designing and making an economical and practical detector for beef freshness. 相似文献

Transposons are sequence elements widely distributed among genomes of all three kingdoms of life,providing genomic changes and playing significant roles in genome evolution.Trichomonas vaginalis is an excellent model system for transposon study since its genome(~160 Mb) has been sequenced and is composed of~65%transposons and other repetitive elements.In this study,we primarily report the identification of Kolobok-type transposons(termed tvBac) in T.vaginalis and the results of transposase sequence analy... 相似文献
