Mere familiarity does not necessarily produce understanding. It is perfectly possible to know something (or someone!) all your life and still never really comprehend what you're dealing with. Like the Irishman in the old joke who received a brand-new toilet from his American cousins: He used the bowl for a foot washer, the lid for a breadboard, and the seat for a frame around the Pope's picture.

By means of two stratifications of experimental days of the Whitetop Project-into categories E and W and into categories air mass and frontal-the effects of cloud seeding on precipitation downwind, upwind, and to the sides, up to 180 miles from the seeding line, were investigated. No significant effects were found for W and frontal days. On the other hand, for E and airmass days, significant an...

Seeding has been critical for obtaining diffraction-quality crystals for many structures. In this article, applications and recommendations for seeding are presented based on examples from our laboratory and other groups. The implementation of seeding in high-throughput crystallization, robotics, and other emerging technologies is also discussed.

Currently, the vast majority of agricultural producers in Southern Federal District with a total area arable land up to 50-70 hectares cultivate three main crops, namely grain ears, usually winter wheat, and row crops – corn for sunflower. Grain ear are sown usual ordinary way, use dotted method. These key agrotechnological features lead need different sowing machines equipped types units. Sinc...

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

Information spreading in complex networks is often modeled as disseminating information with certain probability from nodes that possess it to their neighbors that do not. Information cascades are triggered when the activation of a set of initial nodes – seeds – results in diffusion to large number of nodes. Here, several novel approaches replacing the commonly used strategy of initiating all s...
