background: simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. the aim of this study was to contextualize and assess the validity and reliability of the interprofessional collaborative assessment tool (icar) in an iranian context using simulation.   methods: in this descriptive study, contextualization of the icar was assessed through severa...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...

  Introduction: Several studies have discussed to the electron contamination caused by the air column between the head of linac and patient for photon beams. Since it is not possible to measure the electron contamination with practical dosimetry, the Monte Carlo technique is an appropriate and accurate choice to calculate particle flounce in radiation therapy. The purpose of t...

abstract land surface hydrological models has importance in the determination of soil moisture and temperature, the rate of evapotranspiration, stream flow by emphasis on the land surface physical and dynamic process descriptions. in this research, vic land surface hydrological model has been used for the land surface temperature and stream flow determination. the vic runoff simulation in each ...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

serum albumin is the most abundant protein in blood plasma. its two major roles are maintaining osmoticpressure and depositing and transporting compounds. in this paper albumin-ethanol/water solutionssimulations are carried out by three techniques including monte carlo (mc), molecular dynamic (md) andlangevin dynamic (ld) simulations in aqueous solutions. investigation the energy changes with t...

surfactant molecules are used as interesting tools to study the structure, function and stability of proteins. protonation states of amino acids may be changed in the presence of surfactants. in this work, using experimental observations and molecular dynamic simulation, the effects of sodium dodecyl sulfate on the acid dissociation constants of tryptophan was examined. the acid–base equilibriu...

introduction: the aim of this innovative study was to regenerate a condition that makes it possible to carry out researches in the field on a variety of resorption. materials and methods: in order to develop apical resorption, the root canals of selected teeth were instrumented and then drilled with #4 gates glidden drills. in the next stage, the teeth were submerged in melted rose wax up to 3 ...
