BACKGROUND AND OBJECTIVE The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS Fractional laser treatments using a 1,550-nm erbium-dope...
BACKGROUND Loose, lax skin is a common cosmetic complaint. Previous non-invasive skin tightening devices had modest efficacy and were associated with pain or downtime. New technologies may allow for effective skin tightening with a series of radiofrequency (RF) treatments with no downtime. OBJECTIVE To evaluate the efficacy and safety of a novel bipolar RF device for skin tightening. METHOD...
Skin laxity is an unavoidable consequence of aging and chronic sun exposure. Patients are increasingly turning to non-surgical skin tightening measures for a more youthful look. Non-surgical methods can be effective in treating mild moderate laxity, while offering decreased downtimes fewer serious complications than surgical interventions. This article reviews the major interventions laxity: ab...
Background. Since the misfit of crown has an important role in clinical performance of implant-supported prostheses, and due to the impact of the settling effect on misfit, the aim of this study was to investigate the impact of torque forces on the total lengths of narrow and short implant abutments in different internal implant‒abutment connections. Methods. In four different implant‒abutment ...
the direct torque control (dtc) of interior permanent magnet synchronous motor (ipmsm) offers simple structure and fast torque response. the conventional switching table-based dtc (st-dtc) presents some disadvantages like high torque and flux ripple and also variable switching frequency. this paper investigates the improved st-dtc strategies to reduce both torque and flux ripple in dtc of ipmsm...
BACKGROUND Anecdotally, there have been reports of skin tightening after cryolipolysis, but this has not been studied or reported in the literature. OBJECTIVE This clinical evaluation of patients treated with cryolipolysis in the thighs, abdomen, arms, and back assesses changes to skin texture, laxity, and cellulite at 2 study centers. METHODS From the Vancouver site, a comprehensive review...

since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. in reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. this paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...
