In this paper, we consider the L2-gradient flow for modified p-elastic energy defined on planar closed curves. We formulate a notion of weak solution and prove existence global-in-time solutions with p≥2 initial curves in space via minimizing movements. Moreover, unique to p=2 obtain their subconvergence an elastica as t→∞. Nous nous penchons sur le flot de gradient L2 l'équation p-élastique mo...

the emarat pb-zn mine is located at about 80 km south of the city of arak , iran. i the present mine-scale litho geochemical survey 56 hanging wall samples and 37 footwall samples were taken form exploratory tunnels, drillholes and open pit all samples were taken in the range of 0-40 m from pb-zn veins. the relationship between three variables including concentration of zn in wallwork, distance...

The effect of epinephrine on triacylglycerol secretion was investigated in isolated rat hepatocytes. The effect appeared at concentrations of more than 1 µM and reached a plateau at 10 µM. Epinephrine concentration for half of the maximal bioeffect (EC50) was about 1 µM. Epineplrrine at a concentration of 10 µM suppressed triacylglycerol secretion by 33% and increased its cellular content b...

the adsorption of lead (11) and copper (11) in a fixed bed column using activated carbonprepared from nipa palm nut was investigated. thomas model and yoon and nelson kinetic models were used to analyze the column performance. the rate constant for thomas model increased with increase in flow rate and initial ion concentration but remained constant at varying bed height. adsorption capacity for...
