This paper describes the fabrication process and the method to determine the membrane tension and defects of an inkjet-printed circular diaphragm. The membrane tension is an important parameter to design and fabricate an acoustic sensor and resonator with the highest sensitivity and selectivity over a determined range of frequency. During this work, the diaphragms are fabricated by inkjet print...

It has been hypothesized that a major objective of morphological adaptation in limb-bone diaphyses is the achievement of uniform regional safety factors between discrete cortical locations (e.g. between cranial and caudal cortices at mid-diaphysis). This hypothesis has been tested, and appears to be supported in the diaphyses of ovine and equine radii. The present study more rigorously examined...

Interposed soft tissues can block the anatomical reduction of displaced physeal fractures in children and may necessitate surgical removal. The authors describe a new technique in which they surgically freed the interposed distal-based periosteal flap in an irreducible Salter-Harris type II fracture in a 6-year-old boy and then used this flap in a tension band mode to stabilize the fracture. Th...

Abstract The paper contains the results of an experimental investigation fatigue crack development under mixed-mode I + II and III in heat-treated 42CrMo4 steel. Tests were performed on compact tension shear specimens rectangular cross-section for III. Mixed-mode tests conducted 30 60° loading angle, while test was 45°. Additionally, presents fracture analysis path development.

Clinching technologies are increasingly used to join sheet materials in manufacturing, especially automotive lightweight applications. However, clinched joints have a weak static strength and high protuberance, which influence the application of clinching technology. In order improve decrease protuberance joint, new method aluminum alloy with two-stroke flattening (TFC) was investigated this pa...

In view of the growing tension between dipole anisotropy number counts cosmologically distant sources and cosmic microwave background (CMB), we investigate count induced by primordial perturbations with wavelength comparable to or exceeding Hubble radius today. First, find that neither adiabatic nor isocurvature superhorizon modes can generate an intrinsic dipole. However a mode does induce rel...
