PCI is a simple technique and, with the right tool, can thoroughly puncture any skin easily and quickly. Although a single treatment may not give the smoothing that is seen with laser resurfacing, the epidermis remains virtually normal. When the result is not sufficient, treatment can be repeated. The technique can be used on areas that are not suitable for peeling or laser resurfacing.

the present study investigates the effect of e-mail on iranian learners of english and focuses on teaching thewriting skillvia e-mail. more specifically, the study investigates (a) whether using e-mail has any statistically significant effect on improving high school students' writing skill, and (b) whether the proficiency level has any relation with students’ writing improvement through using ...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

In this note, we consider a SK-type model on Zd for d ≥ 1, weighted by a function allowing to any single spin to interact with a small proportion of the other ones. Both mean field and diluted cases are considered, and we compute the replica symmetric solution at high temperature in those two cases. We are also able to study the influence of some boundary conditions on the replica symmetric sol...

in this paper an application of cellular learning automata (cla) to vlsi placement is presented. the cla, which is introduced for the first time in this paper, is different from standard cellular learning automata in two respects. it has input and the cell neighborhood varies during the operation of cla. the proposed cla based algorithm for vlsi placement is tested on number of placement proble...

Edge-localized modes (ELMs) are cyclic disturbances in the outer region of tokamak plasmas that are influential in determining present and future tokamak performance. In this Letter, we outline an approach to modeling ELMs in which we envisage toroidal peeling modes initiating a Taylor relaxation [Phys. Rev. Lett. 33, 1139 (1974)10.1103/PhysRevLett.33.1139] of a tokamak outer region plasma. Rel...

Healthcare-related research is largely regional. Put simply, this is because disease burdens differ between world regions. Even global burdens, such as ischaemic heart disease and cancer, display distinctive characteristics in certain regions that are not seen in others. Regional differences in infrastructure, resources and human capital further compound the differences seen, as they affect the...
