Flooding is a fundamental and effective data dissemination mechanism for route discovery, address resolution and many other network services in MANET, cause redundant rebroadcasts, which in result leads to the broadcast storm problem. Although many approaches have been proposed to solve the broadcast storm problem, none have been regarded as the satisfying(More)

In this study, an improved cover angle-based broadcasting algorithms is proposed for Mobile Ad hoc Networks (MANETs) to minimize redundancy, contention and collision known as broadcast storm problem in the literature. The propose technique uses only cover angle concept for rebroadcast decision without using neighbors knowledge information’s or(More)
Objective: To study the acute effects of compound ambient air pollution on small airway lung functions among school children in Shanghai. Method: A longitudinal survey on lung functions was conducted among 233 school-children from three schools (A, B and C, located in innerring, mid-ring and outer-ring areas). Lung function test was performed once a week(More)
Using a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) approach we analyzed 18 human colorectal adenocarcinomas for mutations in exons 5, 6, 7, 8 of p53 gene. At the same time, p53 gene product expression was studied immunohistochemically in these 18 cases in frozen sections. The expression of p53 protein was also(More)
