Submerged arc welding also known as sub arc welding has become a chief welding process because of its ability to deposit large amounts of metal with high penetration. The quality of weld depends on bead geometry of the weld which in turn depends on the process variables. This paper deals with the application of factorial design approach for optimising four submerged arc welding parameters viz. ...

The purpose of this paper is to test the feasibility and affectivity of Bragg breakwaters on increasing wave energy by using wave conditions. The Bragg reflection phenomena will depend on the wavelength of surface waves and the spacing of the submerged breakwater. The spacing of the submerged breakwater is the most important parameter for designing a series of submerged breakwaters. In this pap...

In the present paper, the solution of a singular integral equation with logarithmic kernel in two disjoint intervals (0, a)4(b, ∞), (a, b are finite) is obtained by using function theoretic method. The two cases are considered when the unknown function satisfying the integral equation is unbounded or bounded at both nonzero finite end points of the interval. In the latter case, two solvability ...

Macroconidiation in Neurospora crassa is influenced by a number of environmental cues, including the nutritional status of the growing organism. Conidia formation is normally observed when the fungus is exposed to air. However, carbon limitation can induce conidiation in mycclia submerged in an aerated liquid medium. A mutant was previously isolated that could conidiate in submerged culture wit...

A wild-type strain of Streptomyces griseus forms spores both on solid media (aerial spores) and in liquid culture (submerged spores). Both spore types are highly resistant to sonication, but only aerial spores are resistant to lysozyme digestion. Electron micrographs suggest that lysozyme sensitivity may result from the thinner walls of the submerged spores. Studies of the life cycle indicate t...

We investigated the anticancer effects of Antrodia cinnamomea, a medicinal mushroom from Taiwan, on A549 human lung cancer cells using the ethyl acetate extract from submerged culture filtrates. Our results showed that 2,3-dimethoxy-5-methyl-1,4-benzoquinone (coenzyme Q0; CoQ0) derived from A. cinnamomea submerged culture filtrates has anticancer activity. CoQ0 treatment reduced the viability o...

This paper describes the evolution in time and space of wigeongrass (Ruppia maritima) meadows in the Orbetello lagoon, in central Italy, where the control of the submerged vegetation, with a critical coexistence between macroalgae and macrophytes, is the key management problem. While macroalgae are liable to cause dystrophic crises, macrophytes oxygenate and stabilise the sediment and thus cont...

The metabolism of swimming in the platypus Ornithorhynchus anatinus Shaw was studied by measurement of oxygen consumption in a recirculating water flume. Platypuses swam against a constant water current of 0.45-1.0 ms-1. Animals used a rowing stroke and alternated bouts of surface and submerged swimming. Metabolic rate remained constant over the range of swimming speeds tested. The cost of tran...

The submerged, floating, and emergent vascular flora of Lake East Okoboji, Dickenson County, Iowa, was surveyed by the senior author in the summer of 1961, with collections made at 21 stations. Emergent species and one hybrid, and 7 submerged or floating species were found. A comparison is made with a 1915 survey in which a very rich flora of about 18 emergents and 26 submerged or floating spec...

Ganoderma applanatum belongs to the group of white-rot fungi, due to a well-developed ligninolytic enzyme system. White-rot fungi have attracted great scientific attention in recent years, especially with respect to their enzymatic potential for the bioremediation of persistent pollutants. Contrary to G. lucidum, which medicinal properties, as well as ligninolytic enzyme system have been extens...
