Zebra stripes

Postmortem findings include necrotic lesions in the mouth and nose, congestion of the ileocecal valve, engorgement and blackening of the folds in the cecum, colon, and rectum with "zebra striping," enlarged spleen, edematous lymph nodes, and bronchopneumonia. 

Zebra mussel (Dreissena polymorpha) is a freshwater bivalve belonging to the Dreissenidae family. The common name, zebra, refers to the zebra stripes pattern on the shell and the scientific name, polymorpha, is derived from the many morphs or forms which occur in the shell color pattern, including albino and solid black or... 

The nautilus. Nautilus pompUius, has changed little since its ancestors were around several million years ago. It is found at a depth of about 250 metres in warm seas of the Indo-Padfic region. It has a shell that is spirally coiled, with a creamy coloured periostracum with brown, zebra stripes. The centre of the whorl is a nacreous silver-blue which, when used in jewellery, is known as the coque-de-perle (Fig. 10.8). 

A biochemical switch) Zebra stripes and butterfly wing patterns are two of the most spectacular examples of biological pattern formation. Explaining the development of these patterns is one of the outstanding problems of biology see Murray (1989) for an excellent review of our current knowledge.

The molar entropy corresponds to the change of entropy required by the addition of a small amount of the component in order to keep the temperature constant at a given pressure, extrapolated linearly to 1 mol. Statements of this type can make things difficult at first, but actually come up a lot in everyday life. An example when a car traveling at 50 km/h crosses some zebra stripes, it might take 1 s to do so. If we linearly extrapolate the width of the stripes by a factor of 3,600, we obtain a distance of 50 km. That s the meaning of traveling at 50 km/h. ... 

Endosulfan does not bioaccumulate to high concentrations in terrestrial or aquatic ecosystems. In aquatic ecosystems, residue levels in fish generally peak within 7 days to 2 weeks of continuous exposure to endosulfan. Maximum bioconcentration factors (BCFs) are usually less than 3,000, and residues are eliminated within 2 weeks of transfer to clean water (NRCC 1975). A maximum BCE of 600 was reported for a-endosulfan in mussel tissue (Ernst 1977). In a similar study, endosulfan, isomers not specified, had a measured BCE of 22.5 in mussel tissue (Roberts 1972). Tissue concentrations of a-endosulfan fell rapidly upon transfer of the organisms to fresh seawater for example, a depuration half-life of 34 hours (Ernst 1977). Higher BCFs were reported for whole-body and edible tissues of striped mullet (maximum BCF=2,755) after 28 days of exposure to endosulfan in seawater (Schimmel et al. 1977). However, tissue concentrations decreased to undetectable levels 48 hours after the organisms were transferred to uncontaminated seawater. Similarly, a BCE of 2,650 was obtained for zebra fish exposed to 0.3 pg/L of endosulfan for 21 days in a flow-through aquarium (Toledo and Jonsson 1992). It was noted that endosulfan depuration by fish was rapid, with approximately 81% total endosulfan eliminated within 120 hours when the fish were placed in a tank of water containing no endosulfan. 

The zebra blenny (Istiblennius zebra), which is about 6 inches (15.3 cm) long at maturity, makes its home in the intertidal zone of the Hawaiian Islands. The body color varies from blue to yellow, but it is the distinctive dark, vertical stripes along the fish s side that account for its common name. The zebra blenny uses its pelvic fins as props to support its head high in the water, a position that enables the animal to watch for predators and prey. Distinctive, tentacle-like cirri extend down over its eyes. This tiny fish can curl its tail to one side like a coiled spring, then forcefully unfurl it to jump into a nearby tide pool. 

The same patterns, stripes and hexagons, appear in completely different physical systems and on different spatial scales. For instance, stripe patterns are observed in human fingerprints, on zebra s skin and in the visual cortex... 

Zebra Roof. A type of roof for basic Open Hearth steel furnaces, the feature being alternate rings of chrome-magnesite and of silica refractories, hence the name from the dark and light stripes across the roof. The Zebra Roof was introduced in 1947 with a view to combining the merits of the two types of refractory. By 1952 there were 300 such roofs in service in USA alone, but the Zebra Roof was later displaced by the all-basic roof. 

Figure 1.B Zebra mudstone from Argyle Downs Station, East Kimberley, Western Australia. See [ 21al. The dark bands are portions of the mudstone containing 5-6 chemically-precipitated hematite. The light bands ( mm thick) contain only 1% hematite. In other places in the area the rock is not banded but spotted As one moves farther south-west these spots become more mnnerous and coalesce. Most stages can be found between the spotted rock and the well known striped red and white rock." [21a, p. 5 ] Sample provided by A.F. Trendall, Department of Mines, Perth, Western Australia.

Figure 4.2 The stress state of a polymer melt is essential for any computation. A cartoon showing a zebra losing its stripes is a good analogue for the computation of a polymer melt with the wrong model.
