Small RNAs and a diverse array of protein partners control gene expression in eukaryotes through a variety of mechanisms. By combining siRNA affinity chromatography and mass spectrometry, we have identified the double-stranded RNA-binding domain protein Blanks to be an siRNA- and dsRNA-binding protein from Drosophila S2 cells. We find that Blanks is a nuclear factor that contributes to the effi...

Abstract In this study, in order to obtain the maximum possible formability tailor-welded blank AA6061 sheets connected by friction stir welding (FSW) procedure, incremental sheet forming process has been utilized. The results are presented both numerically and experimentally. To limit angle, base FSWed were formed different angles with conical geometry, ultimately, angle for metal is estimated...

Abstract This article is focused main problem during and after FSW especially when joining blanks AA2024 embedded with interlayer strip widths AA7075, in microstructure of the welded zone, that will turn affect its mechanical properties joints. So, a number interlock AA7075 as 1, 1.5, 2, 2.5 3 mm were added between two substrates base metal technique then followed heating cooling procedures to ...

Formability of automotive friction stir welded TWB (tailor welded blank) sheets isnumerically investigated in biaxial stretching based on hemispherical dome stretch (HDS) test infour automotive sheets of Aluminum alloy 6111-T4, 5083-H18, 5083-O and DP590 steel, havingdifferent thicknesses. The effects of the weld zone modeling and the thickness ratio on formabilityare evaluated. In order to car...

Within the manufacturing process planning, blanks are either selected or designed, respectively forms of input material for the manufacture of products. Reviewed in this paper are three types of group blanks: group castings, group forgings manufactured by closed die forging and free forging, and group blanks manufactured by pressing melted metal in casts. The paper also presents requisites for ...
