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) ...
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 ...
The effects of nitrogen nutrition on light interception parameters
(Int Soc Horticultural Science, Leuven 1, 2006)
Parameters of light interception have an important role in plant growth and dry matter production. Those parameters are: leaf area index (LAI), cumulative interception (CI), light interception (I) and light use efficiency ...
Alterations in amount of chlorophyll as indicator of resistance for Chenopodium album L. and Amaranthus retroflexus L. to atrazine
(Springer Heidelberg, Heidelberg, 2006)
Resistance in weeds, as a natural phenomenon or caused by herbicide application, is a major challenge for science and agricultural production. Nevertheless, a small number of plants is naturally resistant or has developed ...
Evaluation of inbred lines as sources of new alleles for improving elite maize hybrid
(Springer Heidelberg, Heidelberg, 2006)
Choice of an appropriate donor of alleles for use in reselection programs of existing inbred lines of maize (Zea mays L.) is crucial to the success of such programs. Well-adapted local inbred lines might be used as donors ...
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 ...
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 ...
Anatomical Injury Induced by the Eriophyid Mite Aceria anthocoptes on the Leaves of Cirsium arvense
(Springer, Dordrecht, 2006)
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, ...
