Study on synthesis and biological activities of novel water-soluble metalloporphyrins

The synthesis and characterization of a series of metal porphyrins, M^II(Por), {Por=dianionic of 5, 10, 15, 20-tetrakis [4-(4′-bromobutyloxy) phenyl]porphyrinato and 5, 10, 15, 20-tetrakis [4-(4′-butyloxypyridine bromide)phenyl]porphyrinato, M=Zn, Cu, Mn, Co, Ni, Ru-CO} were described. The complexes 3a-3e were prepared from the reactions of compound 2 with metal acetates in chloroform, and the treatment of 3a-3f with excess of pyridine gave corresponding complexes 4a-4f. These new compounds were identified by absorption spectroscopies,¹H-NMR and elemental analyses. The results of biological activity testing for 4a-4f revealed that 4a and 4c had stronger inhibiting action on the growth metabolism ofEsche richia coli.

新疆野生郁金香生物学特性及种子发芽特性的研究

对阿尔泰郁金香,伊犁郁金香进行了物侯期及形态学的观测,结果表明,阿尔泰郁金香物候期较伊犁郁金香迟,株形,花形也比伊犁郁金香大。这两种郁金香在石河子地区生长良好。分室温和低温两种发芽环境对伊郁金香种子进行了药剂浸种催芽试验,结果表明,低温是野郁金香种子种处理后,发芽率较对照显著提高,发芽日期也缩短。

Effect of Splice Marking on Fabric Roll Planning

Minimising the fabric loss during spreading can reduce the total production costs of garment manufacturing. Although marker planning is a major determinant of material utilisation, considerable savings on materials also will be made from the area of spreading loss. In the spreading process, it is general to have variance on the fabric yardage between each fabric roll, and the number of splice markings on each cutting lay is also varied. This paper aim to study how the fabric roll planning and the number of splice marks of a cutting lay will affect the material usage in the spreading process. By using a genetic algorithm approach, the amount of fabric to be saved by optimising the fabric roll sequence was derived by comparing the best arrangement and the worst arrangement of the fabric roll sequences of a cutting lay. The result of the study showed that both fabric roll planning and the number of splice marking have effect on the fabric loss. The findings could help the apparel manufacturer to reduce the
