the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Structure and Arrangement of Salivary Gland Chromosomes in Drosophila Species.

goes a profound change in electronic structure on attachment to hemoglobin. The magnetic susceptibility of hemoglobin itself (ferrohemoglobin) corresponds to an effective magnetic moment of 5.46 Bohr magnetons per heme, calculated for independent hemes. This shows the presence of four unpaired electrons per heme, and indicates that the heme-heme interaction tends to stabilize to some extent the...

Cytoplasmic Fine Structure of Sciara Salivary Glands

Cells from the anterior segment of the salivary glands of Sciara coprophila were found to synthesize and secrete into the gland lumen three morphologically distinct types of granule: 1) A large, electron-lucid granule, up to 1 micro in diameter, staining only faintly with pH 2 fast green and the PAS reaction; 2) an ellipsoid granule of moderate density, strongly fast green and PAS positive; and...
