background: oral lesions are among the earliest clinical manifestations of human immunodeficiency (hiv) infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (aids). the purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in hiv/aids patients attending an hiv cente...

Objectives. Several groups in Manitoba, Canada, experience early childhood caries (ECC), including Aboriginal, immigrant, and refugee children and those from select rural regions. The purpose of this pilot study was to explore the views of parents and caregivers from four cultural groups on early childhood oral health and ECC. Methods. A qualitative descriptive study design using focus groups r...

Considering the network structure is one of the new approaches in studying stochastic PERT networks (SPN). In this paper, planar networks are studied as a special class of networks. Two structural reducible mechanisms titled arc contraction and deletion are developed to convert any planar network to a series-parallel network structure. In series-parallel SPN, the completion time distribution f...

the probable lack of some arcs and nodes in the stochastic networks is considered in this paper, and its effect is shown as the arrival probability from a given source node to a given sink node. a discrete time markov chain with an absorbing state is established in a directed acyclic network. then, the probability of transition from the initial state to the absorbing state is computed. it is as...

a shortest path problem is a practical issue in networks for real-world situations. this paper addresses the fuzzy shortest path (fsp) problem to obtain the best fuzzy path among fuzzy paths sets. for this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (ifss) in order to determine the fuzzy shortest path. moreover, this algorithm is developed for ...
