Melissa M. Brown, MD, MN, MBA Gary C. Brown, MD, MBA Peter Kertes, MD It is the philosophy of Evidence-Based Ophthalmology that the best evidencebased medicine should provide the foundation for knowledge, which will allow practitioners to provide the highest quality of medicine for our patients. Although the knowledge of a numerical or statistical change is critical, this information must be ta...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
Background Pediatric acute lymphoblastic leukemia (ALL) is the most common, yet curable childhood malignancy within the pediatric cancers; but in most developed and developing countries cost of cancer treatment in children with ALL is high. So, we specified the range of expenses for the treatment of pediatric cancer and compared the results in devel...
An efficient and sustainable method was developed for electrocatalytic multicomponent synthesis of spirooxindole-chromene derivatives via a green one-pot, three component condensations of cyclic-1,3-diones, malononitrile and isatins inside an undivided cell where potassium bromide was applied as electrolyte in ethanol/DMSO (95/5 v/v) media, and a practical Fe-Mn-O composit...
Mixed model two-sided assembly lines (MM2SAL) are applied to assemble large product models, which is produced in high-volume. So, the sequence planning of products to reduce cost and increase productivity in this kind of lines is imperative. The presented problem is tackled in two steps. In step 1, a framework is developed to select and prioritize customer orders under the finite capacity of th...
one of the most important issues in the management of production is select the best option for each production activity, so that the time and cost of production is minimal and quality is the maximum. considering to the large number of activities and options for each activity, usually, this choice does not have a unique solution and can be used the utility function and assign weights to time, co...
Today's manufacturers face increasingly intense competition and to remain profitable they needed to design, develop and produce high reliable products. One way by which manufacturers attract consumers to their products is by providing warranties on the products. Consumers are willing to purchase a longer warranty period product.

This research reviews and tests two contradicting notions in cost stickiness literature by empirical recognition of the consequences of cost stickiness. Cost stickiness is consistent with both rational resource planning and opportunistic incentives of manager to increase personal benefits arising from status and power. Although both mechanisms involve asymmetric retention of slack, some of the ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
