Thread worms

One revolution of the worm advances the gear teeth in direct proportion to the number of the worm threads. The most commonly used worms have either one, two, three, or four separate threads and are referred to as single-, double-, triple-, and quadruple- thread worms. The number of threads is determined by counting the number of starts or entrances at the end of the worm. 

Infection with parasitic worms in the United Kingdom is usually confined to round worms or thread worms. In tropical and subtropical parts of the world, infection with parasitic worms is common and widespread. There are many drugs available (in the United Kingdom on a named-patient basis) to treat parasitic worm infection. Most anthelmintic drugs work by interfering with neuromuscular transmission causing paralysis of the worm. 

Whipworm (Trichuris trichiurd) adult females are 5 cm long. These worms thread their entire body into the epithelium of the colon, where they feed on tissue juice and small amounts of blood. Infections of several hundred worms may cause irritation and inflammation of the mucosa, with abdominal pain, diarrhea, and gas. Eggs are discharged and passed into the feces. Infections result from the swallowing of eggs that are obtained directly from contaminated soil. Untreated adult worms Hve for years. 

The worm thread is a major factor in worm ratios and is an important feature in worm design. The speed-reduction ratio is equal to the total number of worm-gear teeth divided by the number of worm threads. 

Additional visitors Small white, thread-like enchytraid worms may appear in large numbers in a worm bin. They are harmless, but oan be a sign that the oontents of the bin are rather acidic. 

Body without cilia very elongated, thread-like worms. 

Surfactant solutions with rod-like micelles can have notable viscosities up to six times higher than the water viscosity [37]. This can be explained by the presence of entangled rodlike micelles (often also called worm-like micelles or thread-like micelles) which arrange themselves in a supramolecular transient network [38-41 ]. Such solutions often have elastic properties but they do not show a yield stress. This means that even high viscous solutions flow under the influence of very small shear stress. In this situation they show a zero shear viscosity which is given by ... 

But there was another thread, from von Baer and Haeckel through to Wilson and Conklin, that saw the increase of complexity in each development as the central issue not how the heredity was distributed across the generations, but how that heredity contrived that the offspring developed into that next generation. Barbieri discusses this literature, but from the outside I lived in it. Here organisms with available embryos, particularly sea urchins and marine worms, amphibians and the chick embryo (animals that didn t have genetics)... 

Silk is a fibrous protein produced by several insect species. Commercially, silk is produced from the cocoon stage larvae of the moth caterpillar Bombyx mori, as it has been, in China, for some 4500 years. A single cocoon produces a continuous thread up to 1 km in length, and the protein fibroin contains large amounts of glycine, alanine, tyrosine, proline and serine The peptide chains are arranged in anti-parallel P-sheets which make up the hierarchical structure of the crystalline silk fibres. A number of spiders also produce silk webs, although the fibroin structure is rather different to that from silk worms.

That s when I asked for help. When I got it, you know how much it was It was, and is, seventy-eight dollars a month for the four of us that is all I ever can get. Now you know why there is no soap, no needles and thread, no hot water, no aspirin, no worm medicine, no hand cream, no shampoo. None of these things forever and ever and ever. So that you can see clearly, I pay twenty dollars a month rent, and most of the rest goes for food. For grits and cornmeal, and rice and milk and beans. I try my best to use only the minimum electricity. If I use more, there is that much less for food. 

Fig. 9 is a schematic phase diagram of a dilute aqueous cationic surfactant solution showing temperature and concentration effects on its microstructures. When the temperature is lower than the Krafft point [the temperature at which the solubility equals the critical micelle concentration (CMC)], the surfactant is partially in crystal or in gel form in the solution. At temperatures above the Krafft point and concentrations higher than the CMC, spherical micelles form in the surfactant solution. With further increase in concentration and/or on addition of counterions, the micelles form cylindrical rods or threads or worms with entangled thread-like and sometimes branched threadlike structures. 

The guinea worm infection is a very old parasitic disease caused by Dracuncu-lus medinensis which are enlongated thread-like filarial worms living in the deep connective and subcutaneous tissues of man. The infection has been reported from different parts of Africa, South America and Asia however, it is endemic in Cameroon, Lake Chad, Sudan, Uganda and India. 

The silkworm spins the whole of its cocoon without a stop and the silk therefore is a continuous thread. One cocoon may contain about three thousand yards of silk and about one thousand cocoons would be required to produce 4 oz of useful thread. The spinning of the cocoon takes 3 to 4 days and when it is complete the worm changes into a pupa which may be either male or female. The cocoons producing males are somewhat smaller and more cylindrical in shape than those from which the females emerge (see Fig. 5.24). Although the two glands join at a common orifice they produce separate filaments known as... 

At a concentration close to the CMC, the micelles are generally spherical or close to spherical (see Fig. 2). As the concentration is increased, the micelles may remain spheroidal or grow and become oblate (disk-like) or prolate (rod-like). The giant worm-like or thread-like micelles represent an extreme case of growth into elongated micelles. The worm-like micelles can be linear or branched (see Fig. 2). The hemispherical end caps of thread-like micelles have a larger diameter than the cylindrical body," a result correctly predicted by theory. Micelles can also be ring-like. " ... 

The hob equals a worm, which is divided into single teeth by chip flutes, which are either parallel to the worm s middle axis or helical along the worm. The number of these chip flutes is called number of flutes or number of gashes (nj). The number of threads rai the hob is called number of starts (zo). The heUx angle (yo) of the hob results from the normal pitch (Pn,o) and...
