Time Evolution of the Magnetic Activity Cycle Period. Ii. Results for an Expanded Stellar Sample
We further explore nondimensional relationships between the magnetic dynamo cycle period the Pcyc, rotational period the activity level (as observed in Ca II HK), and other stellar properties by Prot, expanding the stellar sample studied in the Ðrst paper in this series. We do this by adding photometric and other cycles seen in active stars and the secondaries of CV systems and by selectively a...

We further explore our new interpretation of the relationships between the magnetic dynamo cycle period P cyc , the rotational period P rot , the activity level (as observed in Ca ii HK), and other stellar properties by expanding the stellar sample beyond that considered in Paper I (Brandenburg, Saar, & Turpin 1998). We do this by adding photometric cycles of active stars and secondaries of CV ...

15 صفحه اولDESIGNING AN OPTIMIZATION MODEL FOR PREVENTING THE WASTE TIME IN THE ACTIVITY CYCLE OF AN ORGANIZATION
This article proposes an optimization model for preventing the waste of time in the educational and research activities' cycle of an organization such as a university. For this purpose and in order to increase efficiency and prevent the waste of time; the graph theory models have been used. The educational and research activities diagrams of a supposed university is drawn by the use of graphs t...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
