in data envelopment analyze (dea) the scale efficiency in the input-oriented ccr model is less than or equal to the scale efficiency in dea based on the fractional analysis (dea-r). also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in dea and dea-r. in this paper, first, dea-r model with weight restrictions when there is relativ...

The growth-inhibitory effect of cyclocreatine (CCr) and the kinetics of CCr and Na+ cotransport were investigated in MCF7 human breast cancer cells and its adriamycin-resistant subline with use of 31P- and23Na-NMR spectroscopy. The growth-inhibitory effect in the resistant line occurred at a lower CCr concentration and was more pronounced than in the wild-type line. This correlated with an ∼10-...

Abstract The growth of online shopping is rapidly changing the buying behaviour consumers. Today, there are challenges facing buyers in selection a preferred item from numerous choices available market. To improve consumer experience, recommender systems have been developed to reduce information overload. In this paper, cognitive comparison-enhanced hierarchical clustering (CCEHC) system propos...

In this work, the mechanisms of cadmium (Cd2+) adsorption on residual biomasses from husks yam (Dioscorea rotundata), cassava (Manihor esculenta), cocoa (Theobroma cacao), corn (Zea mays) and oil palm bagasse (Elaeis guineensis) were studied in order to evaluate effect temperature, adsorbent dose particle size a batch system. Isotherms kinetics determined adjusted different models. The biomater...

recently, lotfi et al. [10] established an equivalence model between the output-oriented dual ccr model and multiple objective linear programming (molp) and used an interactive method for finding target unit on efficiency frontier such that the decision maker preferences can be taken into account. however their method is not applicable for situations in which some outputs are undesirable and ne...

Aim of this study was to evaluate, in Renal Transplant Recipients (RTR), a new method to predict Creatinine Clearance (Ccr) from Plasma Creatinine (Pcr) and from the value of Body Cell Mass (BCM). The values of BCM were obtained, from body impedance analysis (BIA) using an impedance plethysmograph, in 87 RTR with different graft function. The ratios of 24-hour Urinary Creatinine Excretion (Ucr)...

In order to rationalize material selection in green design, this study presents an attempt combine the methods of generalized Data Envelopment Analysis (DEA) and Technique for Order Preference by Similarity Ideal Solution (TOPSIS). By establishing a index system, G-CCR model DEA was first used select effective materials from candidate samples, TOPSIS then sort suppliers. The combined DEA/TOPSIS...

AIM Nerve entrapment syndromes are the most common causes of neuropathic pain. Surgical decompression is the preferred method of treatment. The aim of this study was to compare the efficacy of curcumin, tramadol and chronic constriction release treatment (CCR), individually or together, in a rat model of sciatic nerve injury. MATERIAL AND METHODS Eighty male rats were divided into eight study...
