Introduction: It is believed that injury potential has a regulatory role in wound healing process and the application of exogenous electrical stimulation may serve to mimic the natural endogenous bioelectric current so that can improve the wound healing. Up to now, this hypothesis has not been researched in surgically acute wounds. Materials and Methods: Thirty nine male guinea pigs were random...

Novel low-energy structures are found on the potential energy surfaces of the neutral, cationic and anionic gold clusters Au5≤n≤8(Z = 0,±1) and on the neutral potential energy surface of Au9. These structures provide new insights on the 2D ⇒ 3D transition in small neutral and charged gold clusters. It is demonstrated that the size threshold for the 2D 3D coexistence is lower for cationic than n...

The growing realization that electrical coupling is present in the mammalian brain has sparked renewed interest in determining its functional significance and contrasting it with chemical transmission. One question of interest is whether the two types of transmission can be selectively regulated, e.g., if a cell makes both types of connections can electrical transmission occur in the absence of...

A new, global analytical potential energy surface is constructed for the X A8 electronic ground state of HOCl that accurately includes the HClO isomer. The potential is obtained by using accurate ab initio data from a previously published surface @Skokov et al., J. Chem. Phys. 109, 2662 ~1998!#, as well as a significant number of new data for the HClO region of the surface at the same multirefe...

the goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. the effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. this is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...
