An "additive" fluent is a fluent with numerical values such that the effect of several concurrently executed actions on it can be computed by adding the effects of the individual actions. We show how queries about additive fluents can be answered using the Causal Calculator. The examples discussed in this paper involve buying and selling, applying forces and moving groups of objects. The additi...

By an additive action on algebraic variety X we mean a regular effective Gan×X→X with open orbit of the commutative unipotent group Gan. In this paper, give uniqueness criterion for complete toric variety.

in this study six genotypes of upland cotton (g. hirsutum l.) were crossed in a half diallel (6×6) mating fashion. the parents and f1s were planted in a complete randomized block design with three replications at the hashemabad cotton research station (gorgan) in 2005. cotton yield and some agronomic traits were evaluated. analysis of variance showed that differences due to genotypes were signi...

Four single crosses (VG20 x SGE48, SGE48 x SG35II, VG26 x SG35II, and SG35II x VG20) in opium poppy (Papaver somniferum L.) were analyzed to study the gene actions involved in the inheritance of quantitative traits, namely plant height, branches/plant, capsules/plant, peduncle length, capsule index, stigmatic rays, straw yield/plant, and morphine content. Simple additive, dominance, and epistat...

Background: A study was carried out to estimate the general and specific combining abilities, as well heterosis for seed yield associated traits in pea lines. Methods: Twenty-eight cross combinations were generated using half-diallel mating design with eight parental The mean values of its contributing lines their offspring each replication used statistical analysis viz., GCA, SCA Heterosis. Re...

generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[sorghum bicolor (l.) moench. six basic generations, namely p1, p2, f1, f2,bc1p1, bc1p2 of four crosses involving seven diverse parents were evaluated inrainy 2009. the mean performance of the f1 in all the crosses indicated dominantgene effect fo...
