Abstract The current study presents a novel Tailored Forming process chain developed for the production of hybrid bearing bushings. In first step, semi-finished products in form locally reinforced hollow profiles were produced using new co-extrusion process. For this purpose, modular tool concept was which steel tube made case-hardening steel, either C15 (AISI 1015) or 20MnCr5 5120), is fed lat...

OBJECTIVE Our objective is to build a model that explains the association between the exposure to trace elements in the soil and the risk of neural tube defects. METHODS We built a function with different parameters to describe the effects of trace elements on neural tube defects. The association between neural tube defects and trace element levels was transformed into an optimization problem...

With using the carbon nano-tube (CNT) of high chemical activity, nano-TiCx particles with different growth shapes were synthesized through the self-propagating high temperature in the 80 wt.% metal (Cu, Al, and Fe)-Ti-CNT systems. The growth shapes of the TiCx particles are mainly octahedron in the Cu- and Al-Ti-CNT systems, while mainly cube- and sphere-like in the Fe-Ti-CNT system.

The present paper deals with the experimental and computational study of axial collapse of the aluminum metallic shells having combined tube-frusta geometry between two parallel plates. Shells were having bottom two third lengths as frusta and remaining top one third lengths as tube. Shells were compressed to recognize their modes of collapse and associated energy absorption capability. An axis...

This paper evaluates three critical plane criteria, namely the Findley, Matake and modified Wöhler curve method compares them to IIW’s implementation of Gough–Pollard criteria. Assessment is conducted on a large set fatigue data thin-walled tube–tube laser beam welded specimens made magnesium aluminum alloys that were tested under proportional/non-proportional constant/variable amplitude loadin...

In this paper, a new geometry has been proposed to increase heat transfer in tubes. The fluid used was water-aluminum oxide (Al2O3) nanofluid. results showed that the study (compared simple tube) addition increasing transfer, reduced flow pressure drop, which is great advantage over previous methods. Reynolds numbers of 2-300 and nanoparticle volume fraction 0-3.5% have investigated. Profile te...

Inadequate drinking water supplies have been cited as a major reason for poor weight gain in broiler production. One of the limiting factors is nipple waterer flow rate. Research demonstrated a constant water flow rate of 25 mL/min impeded BW by approximately 156 g (0.34 lb) at 6 wk of age compared with those having 75 mL/min through the grow out. A device to measure nipple flow rates was devel...
