Background and Aim: In recent years, the family physician plan has been implemented as a main strategy of health system in Iran. Therefore, the necessity to reform organizational structure based on experiences of other countries is felt more than before. The aim of this study was to explore required structures of Family Physician Program to achieve service quality dimensions in Primary Health c...
Despite their notorious vulnerability, traditional passwords remain important for security. In this paper we describe a method for strengthening passwords. Our method does not require users to memorize or to write down long passwords, and does not rely on smart-cards or other auxiliary hardware. The main cost of our method is that it lengthens the process of checking a password.
Abstract A dislocation density-based model for alloy 718 in the annealed state is proposed order to accurately describe deformation behavior of this a wide range thermo-mechanical loadings. The accounts numerous microstructural mechanisms, including strain hardening, grain size effect, dynamic aging (DSA), solid solution strengthening, as well phonon and electron drag which affects movements at...
Loss of one type of sensory input can cause improved functionality of other sensory systems. Whereas this form of plasticity, cross-modal plasticity, is well established, the molecular and cellular mechanisms underlying it are still unclear. Here, we show that visual deprivation (VD) increases extracellular serotonin in the juvenile rat barrel cortex. This increase in serotonin levels facilitat...
In this work, graphene nanoplatelets (GNPs) reinforced magnesium (Mg) matrix composites were synthesised using the multi-step dispersion route. Well-dispersed but inhomogeneously distributed GNPs were obtained in the matrix. Compared with the monolithic alloy, the nanocomposites exhibited dramatically enhanced Young's modulus, yield strength and ultimate tensile strength and relatively high pla...
When a response word bearing an orthographic, acoustic, or semantic relation to a stimulus word is generated rather than read, later recall is enhanced. Such "generation effects" have been attributed to the activation or strengthening of response-specific features in memory and to the activation or strengthening of the relation between a stimulus and response. This series of experiments yields ...
Presynaptic I(h) channels become activated during a tetanus through membrane hyperpolarization resulting from Na(+) accumulation and electrogenic Na(+)/K(+) exchange. I(h) activation is obligatory for inducing long-term facilitation (LTF), a long-lasting synaptic strengthening. cAMP-induced synaptic enhancement also requires I(h) activation, and both processes are sensitive to actin depolymeriz...
