In this research, CaO (calcium oxide) nanoparticles were synthesized by Co-Precipitation method in the absence and presence of Polyvinylpyrrolidone (PVP) via using calcium (II) nitrate. The Polyvinylpyrrolidone (PVP) was used as a capping agent to control the agglomeration of the nanoparticles. The synthesized samples were characterized via SEM, XRD and FTIR techniques. The average sizes of nan...

A 2-chloroethyl ethyl sulfide (2-CEES) gas sensor based on WO 3 /graphite nanocomposite with high selectivity and fast response-recovery properties was successfully developed.

Telematics applications play an essential role in the dissemination of environmental information and environmental measures. This contribution gives an overview of the applications of environment telematics in Europe as a result of two projects which were performed on an international level. The analysis covers the situation in EC countries as well as in CEE countries, with an emphasis on regio...

Professor Cees van der Vleuten has been awarded the 2012 Karolinska Insitutet Prize for Research in Medical Education for his research in evaluation and assessment of medical competences.

Does the use of in-stream structures and woody debris increase the abundance of salmonids? CEE review 05-006 (SR12).

11-Chloro-3-methoxy-2-undecenal was synthesized from 8-bromooctanol, and an annelation reaction with this aldehyde and ethyl acetoacetate proceeded to give the ethyl 6-(8-chlorooctyl)salicylate. Ethyl 6-(8-chlorooctyl)salicylate was converted to ethyl 6-(7-formylheptyl)-2-methoxybenzoate through the iodide after protection of the phenolic hydroxyl group. Finally, the Wittig reaction with the al...

In the present study, ethyl acetate, butanol and aqueous fractions derived from total methanol extract of Butea monosperma flowers were evaluated for radical scavenging activities using different in vitro models like reducing power assay, scavenging of 2,2 diphenyl-1-picrylhydrazyl (DPPH) radical, nitric oxide radical, superoxide anion radical, hydroxyl radical and inhibition of erythrocyte hem...

The antioxidant property of the 70% aqueous ethanol extract of Phyllanthus amarus roots and its ether-soluble, ethyl acetate-soluble, and aqueous fractions were investigated by various in vitro assays. The root extracts showed higher DPPH, hydroxyl, superoxide, and nitric oxide radical scavenging and reducing power activity. Among all the samples, the ethyl acetate-soluble fraction demonstrated...
