Photonics and photochemical stability of aromatic molecules, family related in -structure but different in planarity, rigidity and molecule symmetry
(Elsevier Science Ltd. www.elsevier.com/locate/jphotochem, 2008)
Intramolecular processes and fluorescence properties of 32 specially chosen aromatic molecules, different in degrees of planarity and rigidity,
but family related in -structure are experimentally and theoretically (using ...
Antimicrobial activity of the crude extracts and five flavonoids from the twigs of Dorstenia barteri (Moraceae)
(Elsevier Ireland Ltd. http://www.elsevier.com/wps/find/journaldescription.cws_home/506035/description#description, 2008)
The aim of this study was to evaluate the antimicrobial activity of the crude extract of the twigs of Dorstenia barteri (DBT) as well as that
of four of the five flavonoids isolated from this extract. Gram-positive bacteria ...
Natural radioactivity in the soil samples of Botswana
(Elsevier, www.elsevier.com/locate/radmeas, 2008)
Studies on concentrations of primordial radionuclides in soil samples of Botswana were carried out.
Measurements were made by gamma spectrometry employing a 41% relative efficiency HPGe detector.
The activity of 226Ra ...
Inhibitory response of Raphanus sativus on lipid peroxidation in albino rats
(Oxford University Press, Oxford Journals; http://ecam.oxfordjournals.org/, 2008-03)
In the present study, inhibitory effect of the methanol extract of Raphanus sativus root on lipid
peroxidation has been carried out in normal rats. Graded doses of methanol extract of root of
the plant (40, 80 and 120 ...
Stereoselective synthesis of 3,4,5,6-tetrahydroxycyclohexyl b-amino acid derivatives
(Elsevier Ltd. www.elsevier.com/ locate/tetlet, 2008)
Stereoselective syntheses of racemic (1S,2R,3R,4R,5S,6R)- and (1S,2R,3R,4S,5S,6R)-3,4,5,6-tetrahydroxy
derivatives of 2-aminocyclohexanecarboxylic acid have been achieved by a stereospecific Diels–Alder
reaction between ...
The Effects of Soil Cover on Soil Respiration and Microbial Population in the Mopane (Colophospermum mopane) Woodland of North Western Botswana
(Global Science Books http://www.globalsciencebooks.com/index.php?page=shop.product_details&category_id=1&flypage=shop.flypage&product_id=5&option=com_virtuemart&Itemid=56&vmcchk=1&Itemid=56, 2008)
Soil cover influences soil biological and chemical processes in various ways. The effects of soil cover (bare soil without litter, litter cover,
Mopane tree canopy and grass cover) on soil respiration and microbial ...
Thermal analysis and annealing temperature dependence of electrical properties in Sn10Sb20Se70 glassy semiconductor
(Springer Netherlands, 2008)
The melt-quenched Sn10Sb20Se70 sample in the
bulk form was used to prepare films on well-cleaned glass
substrates by thermal evaporation method. The activation
energy for glass transition (apparent) and crystallization
has ...
Investigating evidence for UV-B induced mutagenesis in dimorphotheca sinuata using the 18S rDNA and rbcL gene sequences
(American-Eurasian Network for Scientific Information. http://www.aensi.org/aeb_online.html, 2008)
The nuclear 18S rDNA and chloroplast encoded rbcL gene sequences were used to investigate the evidence of
residual UV-B induced mutagenesis in Dimorphotheca sinuata plants. The probes were generated by the polymerase chain ...
Prenylated arylbenzofuran derivatives from Morus mesozygia with antioxidant activity
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2008)
Five prenylated arylbenzofurans, moracins Q–U, were isolated from Morus mesozygia (Moraceae). Their
structures were elucidated on the basis of spectroscopic evidence. Along with these compounds, 3b-acetoxyurs-
12-en-11-one, ...
