In this article, we consider a two level supply chain to evaluate the impact ofpostponement strategy on the retailer. Here the cost parameters are *** distance method is used to defuzzify and to obtain the estimation of thetotal cost in the fuzzy sense. The common variable production cost, commonfixed cost and the common unit holding cost per unit time are assumed to befuzzy in nature. Inventory models are formulated for postponement system andindependent system such that the total average inventory cost function per unittime is minimized. Algorithms are given to derive the optimal solutions of theproposed model. Theoretical analysis and the computational procedure helps tostudy the impact of deterioration rate on the optimal inventory policies. Acomparative study between the postponement system and independent systemconsidering fuzzy costs is also made.

Coral bleaching, which is defined as the loss of colour in corals due to the loss of their symbiotic algae (commonly called zooxanthellae) or pigments or both, is oc-curring globally at increasing rates, and its harm becomes more and more serious during these two decades. The sig-nificance of these bleaching events to the health of coral reef ecosystems is extreme, as bleached corals exhibited high mortality, reduced fecundity and productivity and increased susceptibility to diseases. This decreased coral fitness is easily to lead to reef degradation and ultimately to the breakdown of the coral reef ecosystems. recently, the reasons leading to coral bleaching are thought to be as follows: too high or too low temperature, excess ultraviolet exposure, heavy metal pollution, cyanide poison and seasonal cycle. To date there has been little knowledge of whether mariculture can result in coral bleaching and which substance has the worst effect on corals. And no research was conducted on the effect of hypoxia on corals. To address these questions, effects of tem-perature, hypoxia, ammonia and nitrate on bleaching of three coral species were studied through examination of morphology and the measurement of the number of symbi-otic algae of three coral species Acropora nobilis, Palythoa sp. and Alveopora verrilliana. results showed that increase in temperature and decrease in dissolved oxygen could lead to increasing number of symbiotic algae and more serious bleaching. In addition, the concentration of 0.001 mmol/L ammonia or nitrate could increase significantly the expulsion of the symbiotic algae of the three coral species. Except for Acropora nobilis, the numbers of symbiotic algae of other two corals did not significantly increase with the increasing con-centration of ammonia and nitrate. Furthermore, different hosts have different stress susceptibilities on coral bleaching.

Antibiotics, often supplemented in feed, used as a growth promoter, may cause their residual effect in animal produce and also trigger antibiotic resistance in bacteria, which is of serious concern among swine farming entrepreneurs. As an alternative, supplementing probiotics gained interest in recent *** being the most commonly used probiotic agent improves growth performance, feed conversion efficiency, nutrient utilization, intestinal microbiota, gut health and regulates immune system in pigs. The characteristics of Lactobacillus spp. and their probiotic effects in swine production are reviewed here under.

传统的走时地震层析方法都是建立在射线理论的基础上，而实际地震信号的能量是来自一个连接激发点和接收点的菲涅耳体，并非单纯地来自于一条假想的射线。本文的目的是把菲涅耳体的概念引入到层析成像中去，其优点是；①菲涅耳体层析成像会保持数据本身的分辨率；②增强射线覆盖量；③抗误差（在层析正演过程中由于初始速度场的不准确性造成的射线误差）能力强。理论模型测试证实了菲涅耳体层析成像的这些优点。在理论模型的制作中，我们发现了从理论记录上拾取的走时和直接计算的走时存在着差异：当射线穿过高速异常时，理论模型的走时往往小于计算的走时；反之，当射线穿过低速异常时，理论记录的走时又大于直接计算的走时。对于任何一种以射线走时为基础的层析方法，都将会受到这种走时异常的影响。
