U. Neis, T. Blume

Surface waters to be used as resource for drinking water, waste water and sludge produced in treatment processes are very complex media containing soluble, colloidal and particulate matter. Apart from inert or dead matter the colloidal and particulate phase is mainly composed by organic bio-particles (viruses, bacteria, protozoa). Treatment processes like disinfection of potable water, hygienis...

Frustrated Blume-Emery-Griffiths model

A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean < Jij >= J0. Incorporation of a quadrupolar interaction term and a chemical potential leads to a richer phase diagram with transitions of first and second order. The first order transition may be interpreted as a phase...

Enicostema Littorale Blume in Malaria

The amount of cinchona alkaloids and other antimalarials falls far short of India's requirements. The recent introduction of synthetic antimalarials has been a welcome relief. Besides in day-to-day clinical practice it has been observed that patients would like to be treated with indigenous herbs or their decoctions in preference to quinine and its derivatives or the synthetic antimalarials whi...

Antioxidant and antimicrobial properties of Litsea elliptica Blume and Litsea resinosa Blume (Lauraceae).

OBJECTIVE To investigate antioxidant and antimicrobial activities of two plant species, Litsea elliptica (L. elliptica) and Litsea resinosa (L. resinosa). METHODS In vitro method-2,2-diphenyl-1-picrylhydrazyl radical scavenging assay was conducted for antioxidant activity determination while antimicrobial assay consisted of agar well diffusion assay and mycelial radial growth assay.
