Four layers of stainless-steel mesh wick are mounted into the tube. The cell was operated at the second longitudinal resonance with one maximum at the cell center and two maxima at the Brewster windows. The microphone is placed at one maximum near one of the Brewster windows. During operation...
OXYCAPT™ consists of three layers. The drug contact layer and the outer layer are made of cyclo-olefin polymer (COP), and the oxygen barrier layer is made of MGC's novel polyester. The oxygen & carbon dioxide barrier of OXYCAPT™ vial is about 20 times better than that of COP mono...
1. Method of producing bags from paper tube sections (1) with one or more layers, in the case of which at least one end of each tube section (1) in the flat state is drawn open to give a bottom square formation (2), and the resulting sid... F Achelpohl - EP 被引量: 4发表:...
Finally, the release profiles of the layers with two distinct types of release kinetics were measured. The results indicated that the drug release from the interlayer and electrospun membrane showed separate and distinct profiles. Most of the OPC was released rapidly during the 1.5?h of the trial...
The Genalex Gold Lion PX300B combines traditional construction styling with upgraded materials. Gold plated grids, and contact pins afford these tubes extended life by eliminating opportunities for tone-destroying oxide layers to develop. This tube is the highest quality 300B type available and is cons...
with bare-metal stents would close up again, usually within about 6months. Stents are normally made of a metal liketantalumor an alloy such as 316L stainless steel. While these materials typically show reasonable biocompatibility, coating stents with polymer orceramic layershas the potential to ...
Preparation of Web Stock: Sheets of laminate web stock, which consist of various polymers and barrier layers, are prepared in rolls. Printing: The laminate web stock is pre-printed using offset/letterpress, flexographic, or digital methods. ...
heat transfer coefficient of the tube and consequently the overall heat exchange capacity of a condenser using the tubes. Some suitable coatings are referred to as enhanced boiling layers (EBLs), which are known in the art for their applicability to heat transfer surfaces on which boiling occurs,...
Some measurements performed with low air contents (e.g.RAJARATNAM 1965) showed some analogy with a wall-jet flow. The velocity profiles presented the same shape as those in developing shear layers of vertical plunging jets. However the quantitative parameters were different (seetable 6-4). For ...
Over the 8 h running process, the generated solid layers (blue zones in Figure 13) grow faster as the HTF temperature declines. This effect is more noticeable at the lower sections of the domain due to the relatively higher heat removal rates by heat conduction. This is due to the fact ...
