introduction: to assess efficiency as a relative concept, the difference between real and expected values must be determined by comparing the productivity of economic units of industry and the efficiency in potential production conditions. as economic units, hospitals need to utilize efficiency analysis in order to make optimal use of their available resources. therefore, the present study comp...

The nutritional requirements of the Propionibacteria have long been regarded as complex. It has been shown that amino acids, although beneficial, are not essential (Fromageot and Loroux, 1936; Tatum, Wood and Peterson, 1936a; Wood, Anderson and Werkman, 1938). They may be replaced by (NH4)2SO4, but growth of many species is seriously impaired upon such a medium. Thiamin has been reported by Tat...

One of the most complicated decision making problems for managers in supply chain is the evaluation of supply chain performance which can be done in different ways. Though several studies have been developed on supply chain performance evaluation based on balanced scorecard (BSC), a few studies focused on relationships among four perspectives of BSC. This paper focuses on these relationships, e...

background: this study aimes to evaluate the failure to thrive (ftt) recurrent event over time. methods: this longitudinal study was conducted during february 2007 to july 2009. the primary outcome was growth failure. the analysis was done using 1283 children who had experienced ftt several times, based on recurrent events analysis. results: fifty-nine percent of the children had experienced th...

The two-channel Anderson impurity model serves as a prototype for describing heavy-fermion materials with a possible mixed-valent regime with both quadrupolar and magnetic character. We report on the low-energy physics of the model, using a conformal field theory approach with exact Bethe Ansatz results as input.
