OBJECTIVE Why is low resting heart rate (HR) associated with antisocial behavior (ASB), i.e., aggression and rule breaking, in adolescence? Theory suggests that personality traits mediate this relationship but differently with age. In the present study this age-effect hypothesis is tested; we expected that the relationship between HR and aggression would be mediated in preadolescence by the per...

We present a detailed study of the evolution of massive stars of masses 15, 20, 25 and 30 M⊙ assuming solar-like initial chemical composition. The stellar sequences were evolved through the advanced burning phases up to the end of core oxygen burning. We present a careful analysis of the physical characteristics of the stellar models. In particular, we investigate the effect of the still unsett...

Here we employ an in situ optical absorbance measurement technique to study the growth of vertically aligned single-walled carbon nanotubes (VA-SWCNTs) synthesized from alcohol. We present a model that describes the growth process of the array in terms of an initial growth rate and a reaction time constant. The growth rate of the array was found to decay exponentially from an initial maximum, r...

statement of the problem burning mouth syndrome (bms) is a condition presented with burning sensation without any pathologic changes of oral mucosa. since there are no accurate diagnostic criteria and because symptoms are so variable the studies have shown different prevalence. limited studies have been performed to estimate prevalence, of bms in iran and worldwide. purpose this research was co...

We consider a system of reaction-diffusion equations with passive advection term and Lewis number Le not equal to one. Such systems are used to describe chemical reactions in a flow in a situation where temperature and material diffusivities are not equal. It is expected that the fluid advection will distort the reaction front, increasing the area of reaction and thus speeding up the reaction p...

Increased rocket motor performance is a major driver in the development of solid rocket propellant formulations for chemical propulsion systems. The use of increased operating pressure is an option to improve performance potentially without the cost of reformulation. A technique has been developed to obtain burning rate data across a range of pressures from ambient to 345 MPa. The technique com...
