Recently, the concept of proxy re-encryption has been shown very useful in a number of applications, especially in enforcing access control policies. In existing proxy re-encryption schemes, the delegatee can decrypt all ciphertexts for the delegator after re-encryption by the proxy. Consequently, in order to implement fine-grained access control policies, the delegator needs to either use mult...

Protecting existing mangrove forests is a priority for global conservation because of the wide range services that these coastal provide to humankind. Despite recent reduction in rates loss, high historical loss mean there are at least 800,000 ha globally potentially suitable re-establishment. Recently deposited mud banks or intertidal, previously terrestrial, land might additional habitat expa...

In getting software requirement and specification based on existing system, reverse engineering (RE) can be done by creating abstraction views of a system in order to help software engineer maintain and re-engineer it. Requirement engineering and specification in a development of a decision support system (DSS) presented in this paper is replaced by RE approach. Before that, software engineer n...

Many articles over the last two decades have enumerated barriers to and facilitators for evidence use in health systems. Bowen et al’s article “Response to Experience of Health Leadership in Partnering with University-Based Researchers: A Call to ‘Re-imagine Research’” furthers the debate by focusing on an under-explored research area (health system design and health service organization) with ...

Despite extensive research in the domain of requirements engineering (RE), companies still struggle with this discipline. Moreover, practitioners are challenged with developing successful products, services, and systems which address the true needs of their customers. This gives rise to a new research field in the domain of RE, namely artifact orientation. According to the literature, this arti...

wound healing in the skin depends upon the availability of appropriate trace metals as enzyme cofactors and structural components in tissue repair. the present study is a part of a series of experimental investigations to examine the influence of bentonite on skin wound healing. surgically induced skin wounds in 48 young adult male rats were exposed topically to bentonite (12 round wound and 12...

objectives: this study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. materials and methods: class v cavities (4x2x2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. in the control group, single bond (sb) adhesive was applied after etching. in bb+sb...
