in order to investigate the physiological and morphological traits of seven autumn sugar beet (beta vulgaris l.) cultivars (jolge, palma, giada, monotunno, sbsi1, suprema and pp8), under  freezing stress, a study was carried out as a factorial experiment (7×10) based on randomized complete block design with three replications in college of agriculture of ferdowsi university of mashhad. the plan...

The Caenorhabditis elegans locus lin-15 negatively regulates an intercellular signaling process that induces formation of the hermaphrodite vulva. The lin-15 locus controls two separate genetic activities. Mutants that lack both activities have multiple, ectopic pseudo-vulvae resulting from the overproduction of vulval cells, whereas mutants defective in only one lin-15 activity appear wild-typ...

Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended. Is such progress avoidable? If not to be avoided, can events be guided so that we may survive? These questions are investigated. Some possible answers (and some further dangers) are presented. _What is The Singularity?_ The acceleration of technological progre...
