Experimental study of interband and intraband crosstalk in WDM networks

The impacts of interband and intraband erosstalk are studied and compared experimentally. Results show that interband crosstalk can be removed with narrow-band filters and has no influence on signal. Intraband crosstalk will result in signal eye diagram close and BER increasing. When the polarization states of signal and crosstalk align, intraband crosstalk seriously decreases signal quality. But when they misalign, it has little influence. Coherent and incoherent crosstalk are studied experimentally. Results show that coherent crosstalk is less harmful to system performance than incoherent crosstalk.

A comparison of biological activities of a new soya biopeptide studied in an in vitro skin equivalent model and human volunteers

During aging, the epidermis and dermis become thin and an efficient anti-aging product should be able to stimulate the metabolism of senescent fibroblast and keratinocytes, in order to increase the quantity of extra-cellular matrix components such as collagen and glycosaminoglycans. A study performed in parallel on an in vitro skin equivalent model, and in vivo, with human volunteers, demonstrated the efficacy of one specific soya biopeptide for anti-aging properties. Such a biopeptide induces a significant increase of glycosaminoglycans synthesis in vitro and in vivo after a one-month treatment. We also showed that this new cosmetic ingredient is able to stimulate favourably the collagen synthesis in vitro and in vivo. This study provided the proof for anti-aging properties of a new soya biopeptide and also validated the skin equivalent model developed for this experimentation as an alternative method to animal or human testing for some cosmetic efficacy evaluations.     

植物乳杆菌G8菌株产细菌素最佳条件的研究

对甘蓝泡菜的一株产细菌素植物乳杆菌ＬａｃｔｏｂａｃｉｌｌｕｓｐｌａｎｔａｒｕｍＧ８进行研究,确定了在ＭＲＳ液体培养其中细菌素产生的条件。通过Ｌ９３＾４正交试验,筛选出其最佳产细菌素的组合为Ｃ２Ｄ２Ａ１Ｂ２即起始ＰＨ值为６．０;培养温度为３０℃,葡萄糖浓度为０．５％,蛋白胨浓度为１％。     

钙强化酱油的研究

本文用几种钙强化剂对酱油进行了钙强化研究。结果表明,三级酱油比较适合进行钙强化;乳酸钙和醋酸钙是比较适合酱油的钙强化剂;当钙强化量在６００ —７５０ｍｇ／１００ｍｌ 时,钙强化的三级酱油具有不沉淀、不分层、不影响原有风味和热稳定性高的特点。     

馒头品质研究

将不同品种小麦粉按拟定的馒头蒸煮试验配方、方法及评分标准进行了馒头外形尺寸及比容、馒头外皮及内芯白度值、馒头评分的研究。结果表明：灰分低、粉色白、面筋含量、筋力及α－淀粉酶活力适中的小麦粉适于制作馒头。小麦粉蛋白质及面筋含量虽不高,但筋力较强,在一定程度上可弥补蛋白质及面筋含量的不足。此外,添加增白剂的小麦粉制作的馒头肉眼看最白,但其白度值度非最高,然而却最不偏黄。这也进一步验证了增白剂的作用机理是氧化小麦粉中的类胡萝卜色素。

Simulation of the Crashing of Sandwich Structures under Impact Loads by Movable Cellular Automata

Movable cellular automata (MCA) method is applied in the analysis of dynamic characters of ceramic armor composite structures under impact loading. As a new approach, MCA is different from the traditional numerical methods such as the finite element method and boundary element method. Based on the theory of particle mechanics, MCA is applied as a powerful tool in relying specific structural analysis of materials loss and penetrating damages. In this paper the method is used to study responses of multi-layered ceramic plates as a base of armor structures under impact loading, thus assisting further investigations in the crashing process and to improve ceramic armor structures.
