Understanding the solubility of nitrogen gas in tissues is a crucial aspect of diving physiology, especially for air-breathing tetrapods. Adipose tissue is of particular interest because of the high solubility of nitrogen in lipids. Surprisingly, nothing is known about nitrogen solubility in the blubber of any marine mammal. We tested the hypothesis that N(2) solubility is dependent on the lipi...

The solubility of nitrogen in liquid silicon equilibrated with silicon nitride and its dependence on the composition of the atmosphere has been studied in the temperature region 1428–1542 C. High purity silicon was melted in silicon nitride crucibles under Ar and N2 atmospheres. The equilibrium was observed to be established within minutes, after which no evolution of the nitrogen content with ...

Flours from African breadfruit, corn and defatted soybean were thoroughly mixed in a Hobart_-mixer at three variable, with the following combinations 40:5:55, 55:5:40, 70:5:25, 85:5:10 and 100:0:0% for African breadfruit, corn and soybean, respectively. These combinations were hydrated to moisture contents of 15, 18, 21, 24, and 27% and extruded at screw speed of 100, 120, 140, 160 and ISOrpm i...

L. Guerra-Fuentes, A. Juarez-Hernandez, M.A.L. Hernandez-Rodriguez, University Autonumous of Nuevo León, M. Herrera-Trejo, CINVESTAV Ramos Arizpe Coah., Mexico The eff ects of natural aging on the tensile strength, Rm, in a rod of 1004 steel were studied. Natural aging was performed at 298 K over a period of 126 h and values were recorded at diff erent intervals. Electron microscopy observation...
