metal spinning as a kind of manufacturing process has capability to shape hollow components. in present work shear spinning process is used to formplates into conical shapes. moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. this approachwas done by experimental and finite elements method. the resul...

Abstract The paper aims to analyse a fiber optic link by using optics (FT1000EMT, FT800UMT, FT200UMT, FT1500UMT), transmitters (M9-A64-0300, VCSEL-1060-SM, TUVE-1060-T-TO) and receivers (SRP00294, LDPF XXXX), Octave.

We have studied the in vitro biological activities and mechanism of action of 1,25-dihydroxyvitamin D3 (1,25D3) and four potent 1,25D3 analogues [20-epi-22oxa-24a,26a,27a-tri-homo-1,25(OH)2D3 (KH 1060); 20-epi-1,25(OH)2D3; 1,25(OH)2-16ene-D3; and 1,25(OH)2-16ene-23yne-D3] on proliferation and differentiation of estrogen receptor-negative (MDA-MB-436, BT-20, SK-BR-3, and MDA-MB-231), estrogen re...

this experimental study investigated the effects of quenching and tempering heat treatment on fatiguebehavior and also tempering temperature and time holding of aisi 1060 steel. at first, the specimenswere austenitized at 800˚c for 1 hour, and then were quenched in the water bath of 25˚c temperature.after that, tempering process was done at the temperature of 250˚c, 450˚c and 650˚c for 1 and 2 ...

OBJECTIVES To examine the feasibility of automatically segmented choroidal vessels in three-dimensional (3D) 1060-nmOCT by testing repeatability in healthy and AMD eyes and by mapping Haller's and Sattler's layer thickness in healthy eyes. METHODS Fifty-five eyes (from 45 healthy subjects and 10 with non-neovascular age-related macular degeneration (AMD) subjects) were imaged by 3D-1060-nmOCT...

silica refractory bricks are used especially in the metallurgical industries, due to desirable properties suchas high melting point, rigidity, and high temperatures strength. in this research, different amount of sicwere added to silica refractory containing different binders such as borax, boric acid, calcium nitride,sodium tri poly phosphate, sodium hexa meta phosphate (shmp) and lime. physic...
