The thermodynamic properties of the Fe-Mn-C system were investigated by using an analytical model constructed by a CALPHAD approach. The stacking fault energy (SFE) of the fcc structure with respect to the hcp phase was always constant at T0, independent of the composition and temperature when other related parameters were assumed to be constant. Experimental limits for the thermal hcp formatio...

We have carried out a comprehensive survey of the isotopic compositions (H, B, C, N, O, and S) of a suite of interplanetary dust particles (IDPs), including both cluster and individual particles. Isotopic imaging with the NanoSIMS shows the presence of numerous discrete hotspots that are strongly enriched in N, up to 1300&. A number of the IDPs also contain larger regions with more modest enric...

In the present study, the seeds of two date palm (phoenix dactylifera L.) cultivars, Mazafati and Kalutah, were analyzed for their physical properties and chemical composition. Studies were also conducted on properties of oil extracted from the seeds and its fatty acid composition. The seeds constituted about 6-10% of the fruit weight. They, on the average, contained 4.84% protein, 12.22% fat, ...

We claim that a key component of effective Web service composition, and one that has largely been ignored, is the consideration of user preferences. In this paper we propose a means of specifying and intergrating user preferences into Web service composition. To this end, we propose a means of performing automated Web service composition by exploiting generic procedures together with rich quali...

21 kilometres north of Stewart (Figure 2-IZ-l), on the east The Silbak Premier mine is in northwest British Columbia, side of the Salmon River Valley. The original discovery of a that from 1918 to 1953 produced 4.3 million tonnes of ore high-grade vein in 1910 culminated in an underground mine grading 14.6 grams gold and 304 grams silver per tonne from sulphide-bearing stockworkveins and brecci...

Palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. Texture is one of the most important features extracted from low resolution images. In this paper, a new local descriptor, Local Composition Derivative Pattern (LCDP) is proposed to extract smartly stronger...
