OBJECTIVE The paper presents a new trend of weight-for-height index of 2397 school children (1268 boys and 1129 girls) aged 6.5-11.5 years by sex in a representative sample from primary schools of Shiraz (Southern Iran) at an interval of 15 years (1988-2003) and its relation to the Center for Disease Control and Prevention (CDC) data (2000). METHODS The data relate to a multi-stage random sam...

The main purpose of this paper is to provide a methodology for discussing the fuzzy. Bayesian system reliability from the fuzzy component reliabilities, actually we discuss on the Fuzzy Bayesian system reliability assessment based on Pascal distribution, because the data sometimes cannot be measured and recorded precisely. In order to apply the Bayesian approach, the fuzzy parameters are assume...

BACKGROUND Upper gastrointestinal bleeding (UGIB) is a major healthcare problem and is the most frequent gastrointestinal reason for admission to hospital. We aimed to investigate the prognosis of patients with UGIB referred to a referral hospital in northern Iran in 2013. METHODS All patients with UGIB who admitted to Sayyad Shirazi Hospital, in Gorgan, northern Iran, in 2013 were enrolled. Th...

The cost and efficiency of fossil fuel based electric power and heat production in remote areas is an important topic, such as in Alaska with more than 250 remote villages, and developing countries such as Mexico, with approximately 85,000 villages, each with populations less than 1000 persons. The operating cost of fossil fuel based generators such as diesel electric generators (DEGs) is prima...

Vitiligo is a common disorder of skin pigmentation. White spots of the skin are due to loss of melanocytes production (1). Multiple causes have been indicated for this issue by the researchers’ with the autoimmunity as the major one (2). The definitive treatment has not been provided so far. Over the past centuries, plants found in the natural habitat of Iran have thus played an important role ...

Selecting the “best” project portfolio out of a given set of investment proposals is a common and often critical management issue. Decision-makers must regularly consider multiple objectives and often have little a priori preference information available to them. In this paper a new approach to prioritize project portfolio in an efficient and reliable way is presented. It is based on strategic ...

Background Vulvovaginal candidiasis (VVC) is an important health problem caused by Candida spp. The aim of this study was molecular identification, phylogenetic analysis, and evaluation of antifungal susceptibility of non-albicans Candida isolates from VVC. Methods Vaginal secretion samples were collected from 550 vaginitis patients at Sayyad Shirazi Medical and Educational Center of Gorgan (...

Reliability of prognostics and health management systems (PHM) relies upon accurate understanding of critical components’ degradation process to predict the remaining useful life (RUL). Traditionally, degradation process is represented in the form of data or expert models. Such models require extensive experimentation and verification that are not always feasible. Another approach that builds u...
