This study mainly focuses on enhancing the overall efficiency of gas transmission networks. The authors developed a model with detailed characteristics of compressor and pressure reduction stations. Following this, they suggested three different systems with gas turbine including: organic rankine cycle (ORC), air bottoming cycle (ABC), and ABC along with steam injection (SI-ABC). In addition, u...

Introduction: The aim of this study was to investigate whether there is any relationship between the condition of complete dentures and TMDs. Methods: The sample consisted of 61 consecutive patients (35 females and 26 males) who were admitted to the Department of Prosthodontics of Mashhad Faculty of Dentistry for fabrication of new complete dentures.  The age range of the participants was betwe...

TO THE EDITOR—Two systematic reviews and meta-analyses on the efficacy of tigecycline were performed and published in parallel [1–2]. They have reached similar conclusions, that overall mortality was increased in patients given tigecycline. This difference reached significance when all studies were included in our systematic review and meta-analysis [1]. In March 2012, Prasad et al [3] publishe...

Existing plant designs are often conservative and as a consequence the opportunity to achieve full value is lost. Even for well-designed plants, the usage and profitability of mineral processing circuits can change over time, due to a variety of factors from geological variation through processing characteristics to changing market forces. Consequently, plant designs often require optimisation ...

Increased rate of exam failure in mathematics is observed at many educational institutions in the last years. Various approaches have been applied to resolve that problem. Some of them like e-learning methodologies and intelligent tutoring systems are more technologically oriented while others focus on face to face communications and group study techniques. In this work we consider a way to adj...

Background: In this study, we retrospectively reviewed the treatment outcome of 63 patients with T1 early glottic cancer treated with RT alone to determine the treatment outcome and the prognostic factors affecting local control. Materials and Methods: All patients were treated by 6 MV photons with conventional bilateral fields up to a median dose of 66 Gy in 33 fractions. Results: The 5-year l...

The classic overall profit needs precise information of inputs, outputs, inputs and outputs price vectors. In real word, all data are not certain. Therefore, in this case, stochastic and fuzzy methods use for measuring overall profit efficiency. These methods require more information about the data such as probability distribution function or data membership function, which in some cases may no...

The role of non-Archimedean  in the DEA models has been clarified, so that the associatedlinear programs can be infeasible (for the multiplier side) and unbounded (for theenvelopment side) with an unsuitable choice of  . This paper shows that the overallassurance interval for  in DEA models is unique by the concept of extreme directions. Also,it presents an assurance value for  using only s...

An epidemiological study was carried out in the current Nottingham health district to determine changes in both neonatal unit workload and in the infants requiring neonatal care during two study periods. All admissions for 1977 and again for the 12 months 1 April 1983 to 31 March 1984 were reviewed. Total numbers of admissions have shown roughly a 50% reduction because of a more rigorous admiss...
