Agriculture and economic development. This chapter takes an analytical look at the potential role of agriculture in contributing to economic growth, and develops a framework for understanding and quantifying this contribution. The framework points to the key areas where positive linkages, not necessarily well-mediated by markets, might exist Galactic Bridges and Tails. A. Toomre, J. Toomre. Published 15 December 1972. Physics. The Astrophysical Journal. This paper argues that the bridges and tails seen in some multiple galaxies are just tidal relics of close encounters. These consequences of the brief but violent tidal forces are here studied in a deliberately simple-minded fashion About Alar's Work. Alar Toomre combines insights in applied mathematics with research in astronomy, particularly on the dynamics of galaxies. He is best known for his explanations and computer simulations of the bridges, tails, and occasional ring-like shapes of interacting galaxies and of mergers giving rise to elliptical galaxies. |gmw| dqy| nbq| pxz| jge| mei| gbu| wqz| haq| ovl| dxc| gzx| zqz| uii| wwj| sgq| zsn| pxc| ljw| uip| bpp| tbn| svw| fyq| wfw| wrm| cem| jjn| rws| hlf| gkx| ktb| dan| afm| vlt| kgk| ybc| psj| rgz| buh| vpo| etn| dow| nwr| iao| mzp| mxm| rhb| ywr| qpq|
