Effects of Red Shifts on the Distribution of Nebulae.
نویسنده
چکیده
Two new surveys of nebulae, to wpg= 18.47 aQd 21.03,are described which, together w ith three earlier surveys to wpg= 19, 19.4, and 20, indicate the apparent distribution in depth. The numbers of nebulae per square degree, N , to limiting magnitudes m, are represented b y the relation lo g iV = o .6 (m— Am) — 9.052 + 0.005 ,

Spatial and temporal distribution of larvae of coral reef fishes in northern Red Sea, Egypt
The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...

متن کاملChemical composition and origin of nebulae around Luminous Blue Variables
We use the analysis of the heavy element abundances (C, N, O, S) in circumstellar nebulae around Luminous Blue Variables to infer the evolutionary phase in which the material has been ejected. We concentrate on four aspects. (1) We discuss the different effects that may have changed the gas composition of the nebula since it was ejected: mixing with the swept up gas from the windblown bubble, m...
متن کاملDetermination of the Minimum Inhibitory Concentration of the Barberry Extract and the Dried Residue of Red Grape and Their Effects on the Growth Inhibition of Sausage Bacteria by Using Response Surface Methodology (RSM)
Background and Objectives: With regard to the hazards of nitrite, application of natural preservatives in order to reduce the microbial load of meat and meat products is increasing. Owing to their anti-bacterial properties, red barberry and the dried residue of red grape could be suitable replacers for nitrite. Materials and Methods: Agar dilution method was employed in order to determine th...

Based on the nonlocal Timoshenko beam theory, the dynamic stability of functionally gradded (FG) nanoeams under axial load is studied in thermal environment, with considering surface effect. It is used power law distribution for FGM and the surface stress effects are considered based on Gurtin-Murdoch continuum theory. Using Von Karman geometric nonlinearity, governing equations are derived bas...
