Chionaeosides A-D, triterpene saponins from Paronychia chionaea
(Amer Chemical Soc, 2007)
Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-o-alpha-L-ar ...
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC
(Amer Physical Soc, 2004)
We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter ...
Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)
We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ...
Determination of malathion and diazinon resistance by sequencing the Md alpha E7 gene from Guatemala, Colombia, Manhattan, and Thailand housefly (Musca domestica L.) strains
(Maik Nauka/Interperiodica/Springer, 2004)
Organophosphate (OP) insecticides (parathion/diazinon) resistance in housefly (Musca domestica L.) is associated with the change in carboxylesterase activity. The product of alphaE7 gene, which is a member of alpha-esterase ...
A comparative study on stability and decay resistance of some environmentally friendly fire-retardant boron compounds
(Springer, 2005)
Environmental concern accelerated development of new wood preservatives having low mammalian toxicity in addition to high protective effectiveness. PHN 130 and PHN 130 G have been developed recently by KOHMIX Ltd. in Japan ...
The usage of a bismuth film electrode as transducer in glucose biosensing
(Springer Wien, 2008)
A second generation glucose biosensor was developed by using neutral red (NR) as a mediator and a bismuth film electrode (BiFE) as a transducer along with immobilized glucose oxidase. The linear range was between 0.2 and ...
Geochronology and stable isotope signature of alteration related to hydrothermal magnetite ores in Central Anatolia, Turkey
(Springer, 2008)
Hydrothermal iron ores at Divrigi, east Central Anatolia, are contained in two orebodies, the magnetite-rich A-kafa and the limonitic B-kafa (resources of 133.8 Mt with 56% Fe and 0.5% Cu). The magnetite ores are hosted ...
Two biosensors for phenolic compounds based on mushroom (Agaricus bisporus) homogenate: Comparison in terms of some important parameters of the biosensors
(Taylor & Francis Inc, 2008)
Interest in molecular imprinted polymer techniques has increased because they allows for the improvement of some stability characteristics of enzymes. The high stability of molecularly imprinted enzymes for a substrate can ...
The relationship between critical thinking skills and in-class questioning behaviours of English language teaching students
(Routledge Journals, Taylor & Francis Ltd, 2008)
It is important that trainee teachers in the faculties of education should develop their critical thinking skills so that they can meet the expectations and needs of their profession. This study aimed at investigating the ...
Anti C-reactive protein immobilization onto poly(glycidyl methacrylate) microspheres and its use for diagnosis
(Sage Publications Ltd, 2008)
A method for a polymeric carrier based test was developed for the diagnosis of C-reactive protein (CRP) as an alternative to commercial kits. Poly(glycidyl methacrylate) (PGMA) particles were synthesized by dispersion ...
