In order to examine the effect of alumite layer on the fatigue behavior, fatigue tests were carried out on aluminum alloy specimens with two different alumite treatments by means of a dual-spindle rotating bending fatigue testing machine.
Why cells use dual pathway spindle assembly is unclear.
Based on LabVIEW and Visual C++ software platform, a real-time control system was developed to control coordinately the dual-feed spindle to drive the tool electrode.
The emphasis is paid on the process control of the 3D SSMEDM based on macro/micro-dual-feed spindle for higher machining accuracy and efficiency.
In this study, an experimental system with a macro/micro-dual-feed spindle was designed to improve the machining performance of servo scanning 3D micro-EDM (3D SSMEDM), which integrates an ultrasonic linear motor as the macro-drive and a piezoelectric (PZT) actuator as micro-feeding mechanism.
Dual-colour imaging, including spindle pole body (SPB) and kinetochore markers, showed that the foci likely represent centromeres, clustered around the SPB, where cohesin is enriched (Supplementary Figure S2) (Guacci et al, 1997; Blat and Kleckner, 1999).
Thus, the dual control of the mitotic spindle and cell morphology by Lis1 Nde1 establishes an intimate coupling between the two important elements of cell division asymmetry determinant.
The restriction of this complex to the lateral cortex in epithelial cells depends on Dlg, and its dual role in apical-basal polarity and spindle positioning therefore provides a mechanism to couple spindle orientation with the overall polarity of the tissue.
This dual localisation was maintained also following the spindle attachment to the oocyte cortex; the cortex-to-spindle signal ratio, however, increased at this stage.
The meiotic chromosomes play dual function in determination of meiosis: 1) organizing a bipolar spindle formation and 2) inducing cortical polarization and assembly of a distinct cortical cytoskeleton structure in the overlying cortex for polar body extrusion.
