The disordered plant dehydrin Lti30 protects the membrane during water-related stress by cross-linking lipids
No full textDehydrins are intrinsically disordered proteins, generally expressed in plants as a response to embryogenesis and waterrelated stress. Their suggested functions are in membrane stabilization and cell protection. All dehydrins contain at least one copy of the highly conserved K-segment, proposed to be a membrane- binding motif. The dehydrin Lti30 (Arabidopsis thaliana) is up-regulated during cold and drought stress conditions and comprises six K-segments, each with two adjacent histidines. Lti30 interacts with the membrane electrostatically via pH-dependent protonation of the histidines. In this work, we seek a molecular understanding of the membrane interaction mechanism of Lti30 by determining the diffusion and molecular organization of Lti30 on model membrane systems by imaging total internal reflection- fluorescence correlation spectroscopy (ITIR-FCS) and molecular dynamics (MD) simulations. The dependence of the diffusion coefficient explored by ITIR-FCS together withMDsimulations yields insights into Lti30 binding, domain partitioning, and aggregation. The effect of Lti30 on membrane lipid diffusion was studied on fluorescently labeled supported lipid bilayers of different lipid compositions at mechanistically important pH conditions. In parallel, we compared the mode of diffusion for short individual K-segment peptides. The results indicate that Lti30 binds the lipid bilayer via electrostatics, which restricts the mobility of lipids and bound protein molecules. At low pH, Lti30 binding induced lipid microdomain formation as well as protein aggregation, which could be correlated with one another. Moreover, at physiological pH, Lti30 forms nanoscale aggregates when proximal to the membrane suggesting that Lti30 may protect the cell by "cross-linking" the membrane lipids.</p

E-store management using bell-lapadula access control security model
No full textGenerally, the existing store management system does not provide any access control mechanism in order to manage resources. All levels of user have the same right to access the store and borrow the equipment. Therefore, the E-Store management system using Bell- LaPadula access control model was proposed. The prototyping methodology was used to develop the system because methodology model is quickly constructed to test or illustrate design features and ideas, in order to gather user feedback. Moreover, the system is built using hypertext processor (PHP) language. The E-Store system has three types of users, which are known as top management of Welding Department, lecturers and students. The user’s access control is divided by high-level privilege to lower-level privilege. Therefore, each user will have different login interface according to their role and access right to the system. Through the system, high-level user manages in and out equipment flow, manages authorization, view history log in activity and verify complaint report. Lower-level user can view list of equipment, report complaint and damage equipment and borrow equipment. The E-Store management system is expected to manage the store effectively and reduced redundancy issues of equipment requested. The user access right has been assigned based on their access leve
Efficient routing for P2P systems
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2004.Includes bibliographical references (p. 51-55).This thesis examines the problem of locating and accessing an item stored in a large and volatile peer-to-peer system, and presents new ways of organizing items and peers to make this operation fast and efficient. Current structured peer-to-peer routing schemes keep routing information about only a small number of peers in the system, typically logarithmic in the size of the system. They do this under the assumption that it is infeasible to keep more routing information up-to-date since the system is highly volatile. As a result, when a node wants to locate an item, several peers have to be contacted in sequence before enough information is available to determine the location of the item. This makes routing a very long operation. In this thesis, we question this assumption and present two fast peer-to-peer routing algorithms. First, we present a "one hop" routing scheme. We show how to disseminate information about membership changes quickly enough so that peers maintain accurate routing tables with information about all peers in the system. Further, we demonstrate the feasibility of the system with analytical results and simulations. Second, we propose a "two hop" routing scheme for large scale systems of more than a few million peers, where the bandwidth requirements of one hop routing can become too large. This scheme keeps a fixed fraction of the total routing state on each peer, chosen such that the additional delay of routing is minimal.by Anjali Gupta.S.M
