We present algorithmic, complexity and implementation results concerning real root isolation of integer univariate polynomials using the continued fraction expansion of real algebraic numbers. One motivation is to explain the method’s good performance in practice. We improve the previously known bound by a factor of dτ , where d is the polynomial degree and τ bounds the coefficient bitsize, thu...

A review of the publications in traditional medicine indicates that the root of Glycyrrhiza glabra L., Fabaceae, is recommended for treatment of epilepsy. As a renewable source, the leaves of G. glabra var. glandulifera growing in Iran were examined for possible anticonvulsant activity. The anticonvulsant activity of the leaves’ ethanol extract and dichloromethane, f1, n-Hexane, f1A, and methan...

In tobacco (Nicotiana Tabacum) pith, sweet potato (Ipomoea batatas), and carrot (Daucus carota) storage roots, differences were found between cell wall and protoplast peroxidases in their isoenzyme patterns, activity, and reaction to tissue injury.In the pith of elongating tobacco internodes, 90% of total activity was associated with the walls, 80% of which was due to the ionically and covalent...

The antibacterial activity of leaf and root ethanolic extracts as well as crude alkaloids and flavonoids from both the parts of Rhus succedanea were carried against bacterial strains viz. Staphylococcus aureus, Clavibacter michiganensis, Proteus vulgaris and Xanthomonas spp. The antibacterial activity was carried out on nutrient agar medium using disk diffusion method. The flavonoid fraction of...

Euphorbia wallichii a perennial herb growing mainly in Himalayas has been widely used in folk medicines for its medicinal properties. In the present study, the crude methanolic root extract (CME) and its fractions; n-Hexane Fraction (NHF), n-Butanol Fraction (NBF), Chloroform Fraction (CHF), Ethyl acetate Fraction (EAF) and Aqueous Fraction (AQF) of this plant specie were investigated for antio...

Rhizosphere microorganisms play an important role in soil carbon flow, through turnover of root exudates, but there is little information on which organisms are actively involved or on the influence of environmental conditions on active communities. In this study, a 13CO2 pulse labelling field experiment was performed in an upland grassland soil, followed by RNA-stable isotope probing (SIP) ana...

It has been hypothesized that increasing atmospheric CO(2) concentration enhances accumulation of carbon in fine roots, thereby altering soil carbon dynamics and nutrient cycling. To evaluate possible changes to belowground pools of carbon and nitrogen in response to elevated CO(2), an early and a late successional species of pine (Pinus taeda L. and Pinus ponderosa Dougl. ex Laws, respectively...
