background: the iranian healthcare system is primarily an insurance based system. this structure has an important influence on the efficiency and equity of the provision of healthcare in iran. this paper reviews the history of the iranian healthcare system and the impact of the iranian health insurance system on healthcare performance based on the results of interviews with key opinion leaders ...
investigation the archetype of mother can help the reader to understand poes works, especially his fiction, better, if not fully. motivated by internal and external drives to get into the universe in its manifold form poe was impelled to art and, from various modes of art, to symbolism. how much was poe successful to produce works of art has been a matter of dispute among critics. however, ther...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
Most economists would concur that an important role of economic theory is to influence the direction of empirical research, either by posing new questions or by suggesting new answers to old questions. Whether or not modern theory should be judged to be a success on that metric is a frequently debated question, but one on which there has been little systematic investigation. In this paper, we p...
So far many case-study researches have been undertaken to propose suitable models for hull optimization of planning high-speed crafts. In this paper a systematic and generic method is illustrated for the first time to introduce the optimized hull form of craft considering the desired speed and weight. Using semi-empirical Savitsky's method, optimal geometrical parameters of planning high-speed ...
the critical properties of a solute are required for modeling of the solubility by the equation of state. for many compounds, the critical properties are not available. so, group contribution method is utilized as a common method to estimate these properties. but, it leads to the consecutive errors in calculations of the solubility modeling. in this study, soave-redlish-kowang (srk) and peng-ro...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
context:in this review, we discuss empirical and stoichiometric models, which have been developed recently in ssf processes and the influence of environmental conditions on the variables of these models. additionally, new studies on modeling of product formation are also mentioned. evidence acquisition:solid-state fermentation (ssf) is recognized as a cheap process for producing many valuable p...
