The superconductivity was discovered in 1911. In the same year, Sumitomo Electric Wire & Cable Works was established (Foundation was in 1897 as Sumitomo Copper Rolling Works), and laid the first Japan-made high-voltage underground cables. In 2011, we will celebrate the centennial anniversary of the discovery of superconductivity, and a high-temperature superconducting (HTS) power cable will be ...

Aluminum is one of the most common deoxidizers; when it used in melt, refractory inclusions alumina are formed. The presence these non-metallic negatively affects purity liquid steel, mechanical properties, makes casting difficult due to tightening steel-pouring fittings. modification with calcium promotes formation aluminates, which leads an acceleration their removal from metal a higher ascen...

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

It is well known that the mechanical properties of materials depend of the rolling direction, which means that the direction of specimen cutting affect the obtained values. This feature also exists in the welded joint, where the anisotropy is caused by direction of the deposit welded layers. One high-carbon steel is surface welded by flux-cored wire and specimens were cut in order to determine ...

in this paper, we discuss the ways that communication accommodation theory (cat) can be a useful framework for understanding and diagnosing interactional issues in interpersonal and intergroup conflict situations. we argue that the theory’s construct of attuning strategies provides a multidimensional view of mutual adjustment, leading to insights relevant to successful versus unsuccessful confl...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

There is a complicated relation between cold flat rolling parameters such as effective input parameters of cold rolling, output cold rolling force and exit thickness of strips. In many mathematical models, the effect of some cold rolling parameters has been ignored and the outputs have not a desirable accuracy. In the other hand, there is a special relation among input thickness of strips, the ...

Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...
