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, ...
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 ...
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 ...

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) ...
Salt stress
(Physiology and Molecular Biology of Stress Tolerance in Plants, 2006)
Saline water occupies 71% of the Earth area. It is thought that even a quarter of the whole pedosphere is affected by salts (Glenn and O'Leary, 1985), amounting to 950 x 106 ha (Flowers and Yeo, 1995), while 23 % of the ...

(Communications in agricultural and applied biological sciences, 2006)
Aphids and parasitolds on willows and poplars in southeastern Europe (Hornoptera : Aphidoidea; Hymenoptera : Braconidae, Aphidiinae)
(Journal of Plant Diseases and Protection, 2006)
Aphid and aphid parasitoid associations on willows (Salix spp.) and poplars (Populus spp.) in southeastern Europe are reviewed. In total 13 aphid parasitoid species were reared from aphids on these plants. The specific ...
Extraction of useful metals from lead-silver cake in the process of hydrometallurgical zinc production by leaching in calcium-chloride solution
(Bulletin of Electrochemistry, 2006)
This paper shows the result of examining lead, silver cadmium and copper extraction from lead-silver waste cake in the process of hydrometallurgical zinc production. Besides controlling of pH value, the lead-silver cake ...
