In situ mechanical testing procedures for small scale samples in the μm range are rare. For many biological materials sizes in the μm range are typical, such as airflow sensors on crickets and individual components of the hairy attachment systems in insects and geckos (Kiel, 1998; Gorb, 2000). A variety of methods and devices exist for the mechanical testing and analysis of conventional bulk sa...

This article reviews the historical evolution of hepatic vascular clamping and their indications. The anatomic basis for partial and complete vascular clamping will be discussed, as will the rationales of continuous and intermittent vascular clamping.Specific techniques discussed and described include inflow clamping (Pringle maneuver, extra-hepatic selective clamping and intraglissonian clampi...

The large diameter-thickness-ratio KDP crystals are the main optical element in Inertial Confinement Fusion (ICF) device to realize the harmonic generation, thus they need to maintain high quality surface figure, and therefore, research on the influence of force environment (including clamping force and gravity) on harmonic loss is quite necessary. In this paper, grinding mount surface topograp...

A mechanical clamp is presented which clamps one of the actuators of the MEMS-based TEM sample manipulator. The clamp incorporates a relatively large clamp force of 0.5 mN and is able to maintain the clamp force without external power. Although compliant mechanism design in MEMS design requires extra attention because of the relatively large deflections, small actuations forces and relatively l...

Hepatectomy without portal triad clamping may decrease the incidence of liver injury; however, the effects of hepatectomy without portal triad clamping in the treatment of spontaneous rupture of hepatocellular carcinoma (SRHCC) remain unclear. The aims of the present study were to evaluate the therapeutic value of hepatectomy without portal triad clamping in the treatment of patients with SRHCC...

BACKGROUND During total hip arthroplasty (THA) drainage is used by most surgeons. However, the optimal drainage strategy remains controversial. The aim of this prospective cohort study was to determine the safety and efficacy of a four-hour drainage clamping technique in patients undergoing THA. MATERIAL AND METHODS There were 64 patients who underwent THA from March 2012 to December 2015 who w...

Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC) is an item of active management of the third stage of labor (AMTSL). Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC) of preterm neonates results in be...

In this study, the clamping stress and force involved in centering of optical glass lens were evaluated quantified. On basis key design parameters examined clamps, finite element method was applied to predict under various parameter combinations. Support vector regression, Gaussian process adaptive neuro fuzzy inference system algorithm surrogate models established using results obtained throug...
