The weakening of the fatigue strength of turbine blades due to local impa caused by foreign objects (Foreign Object Damage FOD) represents i3 safety risk in modern aviation. It is possible to employ deep rolling to courat component weakening in a particularly effective way. In order to derive a possible process parameter-set in advance, fundamental knowledge regarding the elastic and plastic de...

Strip tearing during cold rolling process has always been considered among the main concerns for steel companies, while several works have been done so far regarding the examination of this issue. In this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. Sensors are placed across the cold rolling tandem mill, to collect information on parameters (such a...

P-selectin, found in storage granules of platelets and endothelial cells, can be rapidly expressed upon stimulation. Mice lacking this membrane receptor exhibit a severe impairment of leukocyte rolling. We observed that, in addition to leukocytes, platelets were rolling in mesenteric venules of wild-type mice. To investigate the role of P-selectin in this process, resting or activated platelets...

Background: The immune-mediated responses in vascular cells may include the increased expression of endothelial adhesion molecules, leukocyte rolling and infiltration, cellular lipid dysregulation and vascular smooth muscle cells (VSMCs) differentiation. Investigating the cellular and molecular events involved in the rolling process is useful for treatment or prevention of the vessel stenosis es...

Starting materials used were 99.8% pure nickel, 99.9% pure iron, 99.9% pure tantalum, and 99.9% pure molybdenum. The materials in a total weight of 500g were melted with a high-frequency induction furnace in vacuum. The melt was poured into an iron mold with an opening of 20mm diameter and 150mm length. After forging, the ingot was reduced to a thin plate 0.3mm in thickness by rolling and a wir...
