Rice in the U.S. is frequently seeded at low rates and treated before sowing with neonicotinoid or anthranilic diamide insecticides to target the rice water weevil. A previous study of the influence of seeding rate on rice water weevil densities showed an inverse relationship between seeding rates and immature weevil densities. This study investigated interactive effects of seeding rate and see...

BACKGROUND Tissue engineering with cell seeded biodegradable material has attracted attention as a novel means of treating the severely impaired heart. Here, we consider optimal preparation of a durable biograft using dynamic and static cultures. METHODS Vascular smooth muscle cells (VSMCs) derived from the rat aorta were seeded onto biodegradable material P (LA/CL) (poly-L-lactide-ε-caprolac...

Streamline seeding algorithms have a long and rich history dating back over two decades. And in recent years algorithms for stream surface placement have been developed. However, stream ribbons have been generally overlooked. We present, to our knowledge, the first stream ribbon seeding strategy. Stream ribbons are a tool for visualizing vector fields and are a common extension of streamlines w...

In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

Seeding strategies have a major influence on the success of viral marketing campaigns, but previous studies using computer simulations and analytical models produced conflicting recommendations about the optimal seeding strategy. We therefore compare four different seeding strategies in two complementary small-scale field experiments as well as in one real-life viral marketing campaign that inv...

With the popularity of BitTorrent-like P2P applications, improving its performance has been an active research area. Super-seeding, a special upload policy for the initial seeder, improves the efficiency in producing multiple seeds and reduces the uploading bytes of content initiators, thus being highly expected as a promising solution for improving downloading performance while decreasing uplo...

This research studies the optimal seeding of a network of consumers who are potential adopters of a technology. This problem has a wide range of applications which include launching a network good, inducing network-based marketing, igniting collaboration in organizations, and stimulating R&D with local spillovers. I have two main results so far. The first result shows that when a firm is unawar...

to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...
