Hemolin is a member of the immunoglobulin (Ig) superfamily and contains four Ig domainsthat are similar to neural cell adhesion molecules. It has been regarded as a recognition molecule at immune challenge in insects. This study showed that hemolin of Plutella xylostella was expressed during pupal and adult stages but absent in all larval instars without any immune challenge. It is, however, strongly induced by the injection of Escherichia coli or its lipopolysaccharide in hemocytes, fat body and gut. A double-stranded RNA (dsRNA) interference experiment revealedits role in activation of prophenoloxidase (PPO) in the hemolymph during bacterial infection. Also its involvement in cellular defense was investigated in its mediation of the adherence of hemocytes to rat blood erythrocytes which was knocked down by its dsRNA. Finally, its physiological significance in pupal stage was confirmed by using dsRNA, which significantly prevented adult development. Therefore, it is concluded that hemolin plays roles in both immune and adult development in P. xylostella.

As the use of vehicle route application and LBS(location based service) are fast grew, the importance of maintaining road network data is also increased. To maintain road data accuracy, we can collect road data by driving real roads with probe vehicle, or using digital image processing for the extraction of roads from aerial imagery. After compare the new road data to current database, we can update the road database, but that job is mostly time and money consuming or can be inaccurate. In this paper, an updating method of using GPS(global positioning system) enabled cell phone is proposed. By using GPS phone, we can update road database easily and sufficiently accurately.

Cellular metals based on Iron have been intensively investigated during the last two decades. Because of the significant decreasing of the structural density of Iron based cellular structures, numerous technologies have been developed for their manufacturing. Besides the tremendous weight reduction a combination with other properties like energy and noise absorption, heat insulation and mechanical damping can be achieved. This contribution will give an overview about the latest state in Iron based cellular materials, including technologies in manufacturing, properties and potential applications.

This paper proposes the heuristic algorithm for the generalized GT problem to consider the restrictions which are given the number of cell, maximum number of machines and minimum number of machines. This algorithm is classified into two stages. First stage is the course to form machine cells. we use the similarity coefficient which proposed and calculate the similarity values about each pair of all machines and align these values descending order. If any machine which is composed of selected similarity coefficient is possible to link the other machine on the edge of machine cell and have regard to restrictions and different kind relation among machines in the machine cell, then we assign the machine to the machine cell. Next stage is the course to form part families using proposed grouping efficacy. This stage is also completed when every part is assigned to the machine cell. The results of using the proposed algorithm are compared to the Modified p-median model. The computational results show that the proposed algorithm provides a powerful means of solving the machine-part grouping problem.

This paper presents the application of integrated mathematical programming approach for the design of cellular manufacturing. The cores of the proposed approach are two phases; concurrently a dealing with exceptional elements(EEs) and cell formation and facilities layout design. A policy dealing with EEs considers minimizing the total costs of three important costs ; (1) intercellular transfer (2) machine duplication and (3) subcontracting. And important issue is the calculation of the number of machines needed by considering the maximum utilization of machines and the available capacity of a machine that can be transferred for intercell moving is an key. Facilities layout design is considered to reflect the real field data such as the operation sequence of the parts to be manufactured. quadratic. The model is formulated as mixed integer programming that is presented to find the optimal solution.
