Tube structures

The tube structure consists ofsmall tubular formations to represent so-called coils and turns (sec the tubes in Figure 2-124c). 

Intrinsic Steei Quaiity refers to the metallurgical and chemical properties of steel products (plate, pipe, tubes, structurals, castings, forgings) supplied to the fabricator for conversion into process equipment. Factors related to deoxidation, controlled finishing temperatures in rolling, and cleaning up of surface defects are included.

Endothelial cell interaction with ECM and mesenchymal cells is a prerequisite to form a stable vasculature. Therefore, after endothehal cell proliferation and maturation, and the formation of endothehal tube structures, surrounding vessel layers composed of mural cehs... 

A problem is related to the observation that some of the ions of the electrolyte during the anodization enter into the tube structure at different concentration levels. While C104 ions are hardly incorporated, S04 and particularly P04 are incorporated into the entire tube to significant levels (some few atomic It is clear that significant amounts of F (about... 

The appearance of tubular myelin-like structures in swollen lecithin was observed by light microscopy well before the systematic investigation of liposomes [351-352]. Similarly, it was also demonstrated some time ago that the addition of calcium ions converted phospholipid liposomes to cochleate cylinders [353]. Subsequent studies have, however, revealed that the system is extremely complex. For example, examination of the phase-transition behavior of synthetic sodium di-n-dodecyl phosphate [(C12H2sO)2PO2Na+ or NaDDP] and calcium di-n-dodecyl phosphate [Ca(DDP)2] showed the presence of many diverse structures [354]. In particular, hydrated NaDDP crystals were shown to form lyotropic liquid-crystalline phases which transformed, upon heating to 50 °C, to myelin-like tubes. Structures of the tubes formed were found... 

An excimer lamp has dual quartz-tube structure, where a metal electrode is set at the inner side of the inner tube, and a mesh-type metal electrode is placed at the outside of the outer tube as shown in Fig. 5. When we apply ac high voltage between two electrodes, the dielectric barrier discharge ignites between two dielectric materials, and reaches an excimer state instantaneously by the excitation of atoms of a filling gas. Then the excimer light is emitted by the... 

An integral CFB (ICFB) was thus proposed to combine the four major component parts in a single concentric-tube structure the fast bed, a circular V-valve (CV-valve), an internal multi-inlet cyclone and its dipleg (Liu, 1990 Kwauk et al, 1991). 

Figure 2.1 X-ray tube structure. X-ray radiation from the anode is guided by the windows of the tube to produce an X-ray beam for diffraction.

The average layer thickness of the first coating (layer 2) on the tube structures shown in Fig. 6.6 must be at least 30 to 40 gm to cover the substrate completely, i.e. to ensure the absence of substrate surface roughness effects on the defect... 

In this marginally compact state, the number of candidate tube structures is somewhat limited. The ground-state structures of a short tube in the marginally compact phase subject to compaction are shown in the bottom panel of Figure 12.3 below.

(B) Transmission electron microscopic (TEM) image of valine tail and aspartic acid head lipid-like peptide note the tube structure with open and closed ends as well as vesicles.

The above descriptions are pure end-member cementation types. However, most tabular cemented units in the Zia Formation show a mixture of characteristics of these end-members. Units that are closest in appearance to the type 1 end-member have excellent preservation of sedimentary structures, with rare pit and tube structures (type 3)... 

The use of an annular bed, however, has two disadvantages. The mass transfer zone concept, suggested by Michaels (2), indicates that due to a short flow path, breakthrough of the adsorbed species is expected to occur shortly after the start of the adsorption stage. In addition, the concentric tube structure containing the annular bed is more complex than that of a tubular bed and reduces the effective bed volume due to the existence of an empty core.
