Adopting the concept of mental accounting, the paper analyzes loss-aversion retailer’s optimal order quantity under buy-back contract in the two-stage supply chain, and proves the existence and uniqueness of the optimal order quantity. Conclusions show: under the certain degree of loss aversion, there exists a unique repurchase price to achieve supply chain coordination; meanwhile, the system’s...

medication errors and adverse drug events can bring about hospitalization, permanent injury, or death. patients due to lack of adequate understanding of instruction may unintentionally misuse a prescribed medicine. the aims of the study were to examine whether patients with low back pain were correctly able to understand physician's instructions regarding drug use and also to identify influenci...

purpose: in order to evaluate the frequency of clinical syndromes and the way of nurses, medical students and teachers in shiraz was studied.   method : subjects completed pms forms for one hundred days continuously. in order to avoid misdiagnosis, these syndromes should be seen at least in two consecutive menstrual periods. of 180 subjects who were given these questionnaire, only 72 subjects r...

Protein internal motions influence observables of NMR experiments. The effect of internal motions occurring at the sub-nanosecond timescale can be described by NMR order parameters. Here, we report that the use of order parameters derived from Molecular Dynamics (MD) simulations of two holo-structures of Protein Kinase A increase the discrimination power of INPHARMA, an NMR based methodology th...

High order modulation nonlinear effects has been appointed as the main limitation in coherent optical fiber transmission. Digital back-propagation algorithms are one of the current studied methods to cope with such impairment and extend the systems maximum reach. In this article, we analyzed the digital back-propagation performance in a 224 Gb/s dual polarization 16QAM optical coherent system. ...

The narrow operating window between pore pressure and fracture pressure makes drilling difficult in some operations. A feasibility study of managed pressure drilling (MPD) is carried out on Iran Darquain oil field. The previous wells drilled in this field showed that mud returns were lost during drilling Gadvan formation. The present work addresses this problem by means of surface back pressure...
