background: the ultimate goal of diabetes control is hba 1c improvement. the purpose of this study was to assess the effect of empowerment model on hba 1c among adolescents with type 1 diabetes. methods: the present semi-experimental study was carried out on some 47 diabetic adolescents in order to investigate the effect of an educational program based on the empowerment model on hba 1c among a...

background: despite their simplicity and the low-cost, the conventional non-contact uv systems have low efficiency in water disinfection. the purpose of this study was to examine the possibility of upgrading these systems by some modifications in order to maximize the water contact with the uv radiation and as a result a better disinfection.    methods: in this study, two enhanced models of non...

Using the quasi-linear viscoelastic model proposed by Fung for the description of the viscoelastic properties of soft biological tissues, the parameters governing their time-dependent behavior are commonly estimated from relaxation experiments. Exact quantification is possible from the response to a step change in the strain. Since it is physically impossible to realize a true step change in th...
