introduction: health system performance assessment provides appropriate information about the status of health systems for governments and communities. therefore, in the recent decade, many countries have focused on performance assessment and reporting in order to develop methods and tools as a mean to help achieving health goals. the present study tries to design an indicator-based model (incl...

in this work the mathematical model of a spatial pattern inchemical and biological systems is investigated numerically. theproposed model considered as a nonlinear reaction-diffusionequation. a computational approach based on finite difference andrbf-collocation methods is conducted to solve the equation withrespect to the appropriate initial and boundary conditions. theability and robustness o...

to evaluate the interfacial morphology and the bond strength produced by the three-step, two-step and single-step bonding systems in primary teeth.occlusal surfaces of 72 extracted human deciduous teeth were ground to expose the dentin. the teeth were divided into four groups: (a) scotchbond multipurpose (3m, espe), (b) adh se (vivadent), (d) optibond all-in-one (kerr) and (e)futurabond nr (voc...

this article is a commentary of an overview on “medical tourism” submitted by lunt and marrion, which describes a framework for the study of the issues related to medical tourism. the commentary attempts to differentiate between the current interest in medical tourism and the time-honored and well-established treatment abroad from countries with underdeveloped health systems. the commentary als...

scheduling of production in flexible manufacturing systems (fmss) has been extensively investigated over the past years and it continues to attract the interest of both academic researchers and practitioners. the generation of new and modified production schedules is becoming a necessity in today’s complex manufacturing environment. genetic algorithms are used in this paper to obtain an initial...

today, students spend only 10 percent of their time in training centers and the major part of their time is spent in home, society and other places. however, significant events happen in this limited time. in addition to training and learning, they are prepared and educated to interact with society. education is an important issue in global educating and training systems. there are different ap...

in order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of agriculture, shiraz university, shiraz, iran. the study was carried out in a factorial experiment laid out based on a completely randomized block desig...

this paper considers the automatic design of fuzzy rule-basedclassification systems based on labeled data. the classification performance andinterpretability are of major importance in these systems. in this paper, weutilize the distribution of training patterns in decision subspace of each fuzzyrule to improve its initially assigned certainty grade (i.e. rule weight). ourapproach uses a punish...

in previous studies we first concentrated on utilizing crisp simulationto produce discrete event fuzzy systems simulations. then we extendedthis research to the simulation of continuous fuzzy systems models. in this paperwe continue our study of continuous fuzzy systems using crisp continuoussimulation. consider a crisp continuous system whose evolution depends ondifferential equations. such a ...

objective(s): nanoparticles (nps) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. the main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. methods: in this study, mesalamine loaded chitosan nanoparticles were pr...
