Oxidation of CO over Ru containing perovskite type oxides
(Elsevier Science Bv, Amsterdam, 2006)
Perovskite type catalysts La0.7Sr0.3Cr1-xRuxO3 (0.025 lt = x lt = 0.100) were synthesized by annealing a mixture of metal oxides and carbonates gradually up to 1000 degrees C in air, and characterized by XRPD, XPS, TPD, ...
Room-temperature interaction of n-hexane with ZSM-5 zeolites - Microcalorimetric and temperature-programmed desorption studies
(Springer, Dordrecht, 2006)
In this work, room temperature interaction of n-hexane with HZSM-5 (Si/Al=20) and ion-exchanged samples containing one (CuZSM-5, FeZSM-5 and MnZSM-5) or two transition-metal cations (Fe,CuZSM-5; Cu,MnZSM-5 and Fe,MnZSM-5) ...
Phylogenetic relationships among Praini (Hymenoptera : Braconidae : Aphidiinae) aphid parasitoids, with redescription of two species
(Brill Academic Publishers, Leiden, 2006)
Phylogenetic relationships among four genera and 25 species of the tribe Praini (Braconidae: Aphidimae) were investigated on the basis of 15 characters (13 morphological and two life history characters) using parsimony ...

Anatomical injury of the leaves of the invasive species, Cirsium arvense (L.) Scop., caused by the eriophyid mite Aceria anthocoptes (Nal.), which is the only eriophyid mite that has been recorded on C. arvense worldwide, ...
Impact of the population of spoilage microflora on the growth of Listeria monocytogenes on frankfurters
(Int Assoc Food Protection, Des Moines, 2006)
Approximately 100 CFU/cm(2) of a five-strain mixture of Listeria monocytogenes was coinoculated onto frankfurters with three different concentrations (10(2), 10(4), and 10(6) CFU/cm(2)) of an undefined spoilage microflora ...
Nonlinear dynamics of brewing yeast cell growth in alginate micro-beads
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
The nonlinear dynamics of brewing yeast cell growth in porous Ca-alginate matrices is considered experimentally and theoretically. The applications of alginate matrices include the reduction of internal mass transfer ...

Petroleum pollutant degradation by surface water microorganisms
(Springer Heidelberg, Heidelberg, 2006)
BACKGROUND: , Aims and Scope. It is well known that the composition of petroleum or some of its processing products changes in the environment mostly under the influence of microorganisms. A series of experiments was ...
Temperature-programmed desorption of n-hexane from hydrated HZSM-5 and NH(4)ZSM-5 zeolites
(Springer, Dordrecht, 2006)
Temperature-programmed desorption coupled with mass spectrometer as a detector (TPD), IR and C-13 NMR measurements are used to study the adsorption of n-hexane on hydrated HZSM-5 and NH(4)ZSM-5 zeolites. The C-13 NMR ...
