Partial detachment

Irradiation for 60 min caused more damage. Partial detachment and desquamation of endotheUocytes from the basal membrane took place (Fig. 30.1c). Thrombocytes, fibrin threads and erythrocytes were found on the surfaces of denudated zones. 

Fig. 18 The model of elementary steps as used in the rate equation and Monte Carlo simulation treatments that reproduced the self-poisoning minimum. A cross-section (row of stems) normal to the growth face is shown. There are three elementary steps differing in their barrier and driving force attachment (rate A) and detachment (rate B) of segments equal to half the chain length, and partial detachment of an extended chain (rate C). The key self-poisoning condition is that attachment of the second half of an extended chain is allowed only if m = 1, i.e. an extended chain cannot deposit onto a folded chain (from [49] by permission of the American Institute of Physics)...

A prosthetic mitral valve (St Jude Medical Silzone) that had been implanted in a 72-year-old woman became partially detached 4 months later, causing acute cardiac failure. The mitral annulus was ulcerated and there were multiple erosions in the tissues in contact with the valve. Histology showed chronic inflammation. 

The yield stress was estimated by assuming that the effective load-bearing cross section decreased as a result of interfacial debonding. For a cubic array of spherical PS particles that are partially detached from the LLDPE matrix (Figure 4), the effective load-bearing cross-sectional area (Aeff) is given by... 

Figure 6.9 shows a scanning electron micrograph of a compound that had poor compression properties. Notice how the top of the compact has partially detached (capping) and how the compact has separated into layers (lamination).

Examination of micrographs of the ridges shows that, from the present viewpoint, some of them might be described as tracks with features partially detached. 

Morphological instability of polymethylmethacrylate (PMMA) film on silicone substrate was reported by B. Jing et al. [10] who found partial detachment of PMMA film from the supporting substrate as a result of formation of PMMA micro- and nanobubbles after immersion in water (Fig. 12.4). 

When modified bitumens are tested, the test is repeated when (a) the difference between the two measurements is >2°C, (b) the metal ball breaks the surrounding bitumen film before touching the lower platform or (c) a partial detachment of the bitumen from the metal ball is observed. 

For pulp manufacture, the PPTA yarn is chopped into short fibers, which are then suspended in water. The suspension passes through a refiner mill similar to the kind used in paper manufacture from wood pulp. In the mill aramid fibers are chopped even further, whereby the cutting action of the rotors gives rise to a random distribution of fiber length. At the same time, some crystalline domains partially detach themselves from the main... 

Scab. (1) A fault in the base-metal for vitreous enamelling the scab is a partially detached piece of metal (which may subsequently have been rolled into the metal surface) and is liable to cause faults in the applied enamel coating. 

Similar mechanisms implying at least two steps with partial detachment of a ligand molecule have been proposed in the literature for other bidentate ligands , ... 

During the fifth phase, partial detachment of the biofilm occurs. Due to continuous growth, the thickness reaches a limit at which, e.g., the biofilm s resistance to shearing forces, is exceeded. Flakes of the biofilm may thus be detached and washed away. If the flakes find new sites for adhesion, they may grow again. In closed systems, this causes spreading of the biofilm.

Figure 1 Low-power (200X) micrograph of human adult skin showing the dermis (A) and epidermis (B). The nucleated basal keratinocytes define the beginning of the viable epidermis which is composed of five to six cell layers. As the basal keratinocytes migrate to the surface of the skin, they flatten and lose their nucleus until they resemble thin sheets. At this point, the keratinocytes are called comeocytes and this layer is called the stratum comeum (C). In this sample, the stratum comeum is partially detached due to tissue processing. However, note the onionskin-like appearance of the stratum comeum. Beneath the basal keratinocytes is the dermis (A). The dermis is composed of a pale-staining papillary (PD) layer and dense reticular (RD) layer. Note the prominent collagen bundles (arrows) within the reticular layer.

S. Bahadur (Iowa State University) Did you estimate the error involved that results due to ignoring the stretching of the highly elastic thin rubber filament that gets partially detached from the bulk material due to abrasion ... 

However, if the specimen is bent at 90°, a partial detaching was noticed (see Figure 19) suggesting the presence of a thin oxide layer that hinders the direct contact between A1 and Ni deposit.
