BACKGROUND Tip-plasty is a particularly challenging stage of aesthetic nose surgery. The diversity of nasal tip deformities has necessitated the development of numerous surgical techniques that can be difficult to master and may yield unpredictable surgical results when combined. OBJECTIVES The authors describe how concomitant overlap steal tip-plasty (COST) can enable surgeons to address all...

Background: The technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the dome or tip defining point. The incision di-vides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. The present study aimed at assessing a new vertic...

In terms of policy, the Ministry of Construction has prepared and issued a Guidelines for Green Ecological Residential Area Construction Elements and Technical, China Ecological Residential Technology Evaluation Manual, Environmental Impact Evaluation Law of the People’s Republic of China and other documents; in practice, economically developed areas combined with their own characteristics have...

Tip clearance inevitably exists in helico-axial flow multiphase pumps, which generates a great impact on characteristics. To select reasonable tip and improve the transporting efficiency, different clearances (Rtc = 0.5, 1.0, 1.5 mm) are chosen to investigate behaviors hydraulic Based shear stress transport k-ω turbulence model, unsteady Reynolds averaged Navier–Stokes equations applied solve f...

We experimentally study the effects of normal stress differences in immiscible radial viscous fingering instability a Hele–Shaw cell. Dilute low molecular weight poly(ethylene oxide) (PEO) solutions are used as displaced fluid to focus on elastic without shear-thinning behavior. The PEO is varied investigate differences. experimental observations reveal that nonmonotonic and opposing evident de...

Regulatory T cells (Tregs) are considered to be key immunomodulatory cells of the immune system and are increased in chronic lymphocytic leukemia (CLL). Rai stage 0 identifies patients with early stage CLL for which there is no effective intervention at the present time and a "wait and see" policy is usually adopted. Some biological and clinical studies have reported that green tea constituents...

We study electronic and topographic properties of the Si(335) surface, containing Au wires parallel to the steps. We use scanning tunneling microscopy (STM) supplemented by reflection of high energy electron diffraction (RHEED) technique. The STM data show the space and voltage dependent oscillations of the distance between STM tip and the surface which can be explained within one band tight bi...

Since the atomic force microscope (AFM) has evolved into a general purpose platform for mechanical experiments at the nanoscale, the need for a simple and generally applicable localization of the AFM cantilever in the reference frame of an optical microscope has grown. Molecular manipulations like in single molecule cut and paste or force spectroscopy as well as tip mediated nanolithography are...
