This paper presented a new two-stage green supply chain network, in which includes two innovations. Firstly, it presents a new multi-objective model for a two-stage green supply chain problem that considers the amount o...

objective: adaptation of the pharyngeal airway space does occur after different surgical strategies of class iii patients including mandibular setback, maxillary advancement and bimaxillary surgery. the aim of this study is to conduct a detailed cephalometric evaluation of the alterations taking place in the morphology of the pharyngeal airway space after treatment of class iii skeletal deformi...

Based on approximately 25,000 Student Course Evaluation Questionnaires (SCEQ) covering 16 semesters from Spring 2005 through Fall 2012 and publicly available at the University of Maryland, Baltimore County’s website http://www.umbc.edu/oir/sceq/index.html, we analyze the effect of class level and discipline on student responses. We compare the results obtained and conclusions drown with those a...

template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. cadmium oxide (cdo) nanoparticles were synthesized by using sodium dodecyl sulfate (sds), cd(oac)2.2h2o and sodium hydroxide as starting materials. the sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem). the xrd pattern proves that the final produ...

However, despite this clear statement, when considering the implementation of smaller classes, not all research studies carry the same weight. Many of the ambiguous and contradictory findings in this area are due to a large number of poorly designed and inadequate studies. A useful distinction is made by Goldstein and Blatchford (1998) between those studies which seek to answer descriptive ques...

Bowhead whales (Balaena mysticetus) summering in the eastern Beaufort Sea in 1983 were measured through aerial stereophotogrammetry. Photos were taken from a turbine Aerocommander 690 with wingtip-mounted, calibrated 35-mm cameras. Photos were measured on an analytical plotter with scale data provided by radar altimeter and focal length of the lenses. Coefficient of variation of known-sized tar...

Current palliative pharmacotherapy of Alzheimer’s disease based on the cholinergic hypothesisled to the development of four cholinesterase inhibitors. These compounds can bring prolongationof the symptom-free period in some patients. This is the frst report directly comparing donepeziland rivastigmine plasma and brain levels in <span class="font...
