Abstract Background Hepatic vein embolization in double vein embolization (DVE) can be performed with transhepatic, transjugular or transfemoral access. This study evaluates the feasibility and technical success of using a transfemoral access for the

Powder metallurgy (PM) steel with enhanced density is essential for meeting the demands on high strength and high-performance applications. In this study, cold isostatic pressing (CIP) is applied for consolidating water-atomised iron and Cr-alloyed s

In this paper, we use Oven Desorption followed by Karl Fischer Titration (KF), to measure moisture content in metal powder. In a PBF-LB Hastelloy X powder, from a newly opened container, we found 28.8 ppm (or µg/g). In a stored PBF-EB powder we foun

Carbon is a key element for powder metallurgy. For example, carbon is the basic alloying element in PM sintered steel, and carbon powders are used as a carbon source for the production of hard metals. However, there are only a few studies about the m

Water atomised steel particles are covered by heterogeneous surface oxide, formed by thin (~6 to 8 nm) iron oxide layer covering most of the powder surface, and particulate features formed by thermodynamically stable oxides containing e.g. Cr and Mn

Reaching high density in PM steels is important for high-performance applications. In this study, liquid phase sintering of PM steels by adding gas-atomized Ni-Mn-B master alloy was investigated for enhancing the density levels of Fe- and Mo- preallo

Recent studies have reported that components of the renin-angiotensin system (RAS) are expressed in venous malformations by embryonic stem cell-like subpopulations. It has been hypothesized that these cells are sustained by the RAS and, therefore, co
