severe plastic deformation (spd) methods were developed for producing of metals and alloys with ultrafine grained (ufg) microstructures having high strength. parallel tabular channel angular pressing (ptcap) as a noble severe plastic deformation (spd) method was used to produce ultrafine grained (ufg) and nanostructured cu-30%zn tubes. in this paper, the effect of ptcap process temperature on t...

This research presents the numerical and empirical efforts to investigate effect of friction stir welding (FSW) parameters on weld temperature, strength, hardness for novel brass known as yellow 405-20. The approaches used measure temperature strength were studied first time 405-20 their validations via studies. Two models simulated including transient thermal analysis static structural analysi...

BACKGROUND [123I]FP-CIT is a well-established radiotracer for the diagnosis of dopaminergic degenerative disorders. The European Normal Control Database of DaTSCAN (ENC-DAT) of healthy controls has provided age and gender-specific reference values for the [123I]FP-CIT specific binding ratio (SBR) under optimised protocols for image acquisition and processing. Simpler reconstruction methods, how...

The Brass project aims to deliver software virtual musical instruments (trumpet, trombone, tenor saxophone) based on physical modelling. This requires to work on some aspects of the playability of the models so that they can be played in real time through a simple keyboard : better control of the attacks, automatic tuning, humanization.

Wire electric discharge machining (WEDM) is one amongst the unconventional processes which might cut all kinds of shapes with an accuracy +/?0.001mm. It will materials that conduct electricity and can even exotic metals like tungsten carbide, Hastelloy, Inconel etc. In present work, on 600 by wire EDM cryogenically treated brass performed. Brass 0.25mm diameter has been at ?90 ° C, ?100 C ?110 ...

Electrical Discharge Machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). Inconel 718, which is widely used in the Medical, Marine, Architectural and food processing industries, is used as a work material. The tool electrode materials used are brass. Experiments are conducted using face centered central comp...

Abstract The Foyemiaowan-Xindiantai cemetery, with more than 10,000 tombs, is located in north-west Gansu Province. cemetery was active during the Sixteen-State Period of Western Jin Dynasty (265–439 CE). As largest ancient tomb group Dunhuang region, its cultural core still mainly based on tradition Central Plains. Metal objects were texturally and chemically analyzed by optical microscopy (OM...

Abstract Surface analysis of 2-mercaptobenzothiazole (MBTH) adsorbed on brass from 3 wt.% NaCl solution was performed by means X-ray photoelectron spectroscopy and tandem (MS/MS) time-of-flight secondary ion mass spectrometry (ToF-SIMS). These surface analytical techniques were used in association with the gas cluster beam (GCIB) sputtering method at various acceleration energies sizes, which s...

PURPOSE The goal was to establish an accurate method for measuring intraocular pressure (IOP) in living adult zebrafish and to determine the average IOPs of genetically different strains and mutants. The overall purpose was to develop the zebrafish system for studies of IOP and glaucoma. Elevated IOP and anterior segment dysgenesis are two known risk factors for glaucoma. Because albino mammals...
