Received: June 12, 2017 Revised: October 24, 2017 Accepted: November 03, 2017 Abstract: Background and Objective: Prestressed high strength concrete pipe pile (PHC) shows brittle fracture when subjected to more than its own bearing capacity. Therefore, the non-prestressed steel bar is added to the PHC pipe pile, that is, the mixed reinforced pipe pile (PRC). The mechanical behavior of PRC group...

This paper describes studies done at HP Labs on the actuator pivot bearing nonlinearity of a small disk drive. Part I of this paper presents a frequency-domain approach, using the sweptsine/describing function method, to obtain a model for this nonlinearity. Part II presents several additional models and discusses a time-domain approach, comparing simulated and lab measured torque versus displa...

Seventy patients who had sustained supracondylar fractures of the humerus as children were examined. Loss of carrying angle of the elbow occurred if the fracture was immobilized in a varus position during healing. Varus malalignment could have been obviated if comparative radiographs of the other elbow had been taken and the Baumann angles compared. Rotation and posterior displacement at the fr...

Two series of benzamides compounds bearing piperidine groups were synthesized and the Gli-luc luciferase activity was screened by Gys-luc luciferase gene detection method. Compound 5q showed promising inhibition of hedgehog (Hh) signaling pathway. To further verify whether the Hh inhibitory activities of the target compounds are derived from their inhibition to the Smoothened (Smo) receptor, th...

Among all kinds of journal bearings, the tilting pad bearing has characteristics high stability. In order to further reduce vibration and improve stability rotor-bearing systems, a novel double layers flexible support (DL-FSTPB) is presented in this paper. The utilizes two springs, which have different functions. offset springs control swing angle ensure formation convergent oil film, symmetric...

The dispersion of torsional wave in transverse and layered one-dimensional component of infinite length is investigated. The study is carried out by treating the one-dimensional component as a cylinder of infinite length firstly, Then put forward a way that the component is divided into a multilayer to analyze torsional wave propagation, the model is constructed in cylindrical coordinates for h...

We investigated the stability of seven Schatzker type II fractures of the lateral tibial plateau treated by subchondral screws and a buttress plate followed by immediate partial weight-bearing. In order to assess the stability of the fracture, weight-bearing inducible displacements of the fracture fragments and their migration over a one-year period were measured by differentially loaded radios...

Electrostatically actuated nanoelectromechanical switches based on intershell displacement mechanisms within batch fabricated, bidirectional multiwalled carbon nanotube MWNT bearings are reported. Multiple devices with a 220 nm pitch are constructed within individual MWNT supermolecules. Experimental results on performance metrics including low switching voltages 0.8 to 6 V , repeatability, hys...

BACKGROUND There is a greater prevalence of lower extremity malalignment in obese children during static posture; however, there has been less examination of dynamic joint function in this cohort. Therefore, the purpose of this study was to determine kinematic differences that exist between obese and non-obese children that would support previously reported static joint malalignment. METHODS ...
