the effects of rootstocks such as 'sour orange' (citrus aurantium l. var. ‘yerli’), 'carrizo' and 'troyer citranges' (citrus sinensis osb. x poncirus trifoliata raf), 'smooth flat seville sour orange' (citrus spp. hybrid of uncertain origin), 'brazilian sour orange' (citrus aurantiam l. var. ‘brasilian’), 'volkameriana' (citrus volkameriana tan. and pasq.) and 'calamondin' (possibly citrus reti...

although most parts of iran is free of malaria owing to appreciable struggle against this disease by the ministry of public health, in every case of fever of unknown origin (fuo) possibility of malaria should not be neglected. unjustified administration of antibiotics can delay the diagnosis because of diminishing effect in number of malaria parasites in peripheral blood. for this reason freque...

There is a common problem of operating on hash values of elements of some database. In this paper there will be analyzed informational content of such general task and how to practically approach such found lower boundaries. Minimal prefix tree which distinguish elements turns out to require asymptotically only about 2.77544 bits per element, while standard approaches use a few times more. Whil...

We hypothesized that tree form, recorded in historical public land surveys, would provide a valuable proxy record of regeneration patterns during early-European settlement of North America's eastern deciduous forest. To test this hypothesis, we tallied stem form fromwitness trees used in land survey records in the southern Appalachian Mountains from 13 counties spanning four physiographic provi...

Phylogenies describe the origins and history of species. However, they can also help to predict species' fates and so can be useful tools for managing the future of biodiversity. This article starts by sketching how phylogenetic, geographic, and trait information can be combined to elucidate present mammalian diversity patterns and how they arose. Recent diversification rates and standing diver...
