Methicillin resistant Staphylococcus aureus is one of the major bacterial disease in humans and animals worldwide. It causes opportunistic infections acquired from different sources like patients and hospital staff mainly through their hands besides from their normal flora. The present investigation deals with the prevalence and molecular aspects of 50 Staphylococcus aureus isolates collected f...

Classically, regular homomorphisms have been defined as a replacement for Abel--Jacobi maps smooth varieties over an algebraically closed field. In this work, we interpret morphisms from the functor of families trivial cycles to abelian and thereby define in relative setting, e.g., schemes parameterized by variety given that general establish existence initial homomorphism, going name algebraic...

background and aims. the present study evaluated the most common reasons for replacing amalgam restorations in a university clinic. materials and methods. a total of 217 restorations which needed to be replaced were clinically and radiographically evaluated in a period of 4 months. the frequencies of reasons for replacing amalgam restorations were calculated: the assessed items included recurre...

age replacement policy is concerned with finding an optional time tominimize the cost, at which time the unit is replaced even if itdoes not fail. so far, age replacement policy involving random agehas been proposed. this paper will assume the age of the unit is anuncertain variable, and find the optimal time to replace the unit.

predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. so, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

background & aim: repair or replacement of restorations is one of the main necessities for health promotion. however, it has its own physical, psychological and economical side effects. the aim of this study was to investigate the prevalence of factors causing restoration replacement or repair. methods & materials: a non probable sampling was used for this cross – sectional observational descri...

a greenhouse experiment was conducted to evaluate the competitive effects of different densities of wild mustardas against rapeseed. the experiment was performed in a randomized complete block design with four replicationsusing replacement series in which wild mustard and rapeseed were respectively planted in different ratios of 4:0, 3:1,2:2, 1:3 and 0:4 plants per pot. results indicated that t...
