In a recent article in Nature [1], titled Gain-assisted superluminal light propagation, experimentalists reported observing a laser pulse propagating faster than the speed of light through a gas cell which served as a amplifying medium. They state that the "peak of the pulse appears to leave the cell before entering it". This article generated a great deal of press attention around the world. F...

in iran, cheyletid mites (acariformes: cheyletidae) were collected over 15 years (1996–2010) in stored cereal. samples were collected from silos, flour-mills, barn and rice-mills in 12 provinces scattered throughout the north,  centre, east and west of iran. 8 genera and 13 species were recorded: acaropsellina sollers (kuzin, 1940), cheletomorpha lepidopterorum (show, 1794), cheyletus bidentatu...

chamran 2 cultivar with the pedigree attila 50y//attila/bacanora, originated from national cereal breeding program by crossing between chamran cultivar and  attila line in karaj (1996-97). the f1 plants were evaluated and selected in 1997-98 cropping season. the new cultivar was evaluated in six warm and dry southern research stations of the country (2004-2006). chamran cultivar with good adapt...

Between 2005 and 2008 the prices of rice, wheat and maize were more than doubled (von Braun, 2008). The sudden surge in cereal prices led or was led by major uncertainties to secure staple food supplies in many developing countries, especially in Asia. Several economic and social factors collectively appear to have triggered the unstable supplies of cereal crops during the recent food crisis (H...

Rice is one of the most important crops in the world. Although genetic improvement is a key technology for the acceleration of rice breeding, a lack of genome information had restricted efforts in molecular-based breeding until the completion of the high-quality rice genome sequence, which opened new opportunities for research in various areas of genomics. The syntenic relationship of the rice ...

A new product implicated in cereal grain polysaccharide cross-linking has been authenticated by independent synthesis. Saponification of cereal grain fiber releases the RRRS/SSSR-isomer of 2,5-bis-(4-hydroxy-3-methoxyphenyl)-tetrahydrofuran-3,4-dicarboxylic acid. The parent ester logically derives from 8-8-coupling of ferulate followed by water addition to one of the incipient quinone methide m...

Northern countries like Finland, Canada, and Scotland have a long tradition of using oats in a variety of foods. Even in these countries, however, the consumption of oats is low in comparison with that of other cereals. Processing of oats is required to provide edible products that are stable in storage and have good sensory properties. Traditionally, oats are used as whole grains. The developm...
