Influence of processing conditions on the thermal decomposition of SrTiO3 precursors
(Springer, 2007-03-01)
The present work investigates the influence of milling and calcination atmosphere on the thermal decomposition of SrTiO3 powder precursors. Both pure and neodymium-modified SrTiO3 samples were studied. Milling did not ...
A HIERARCHICAL DECOMPOSITION OF DECISION PROCESS PETRI NETS FOR MODELING COMPLEX SYSTEMS
(International Journal of applied mathematics and computer science, Vol. 20, No. 2, 2010)
We provide a framework for hierarchical specification called Hierarchical Decision Process Petri Nets (HDPPNs). It is an extension of Decision Process Petri Nets (DPPNs) including a hierarchical decomposition process that ...
Decomposition kinetics of iron (III)-diclofenac compound
(Springer, 2009-08-01)
Non-isothermal decomposition of iron (III)-diclofenac anhydrous salt was investigated by thermogravimetry (TG) under different conditions in opened and closed alpha-alumina pans under nitrogen atmosphere. To estimate the ...

(Springer, 2007-03-01)
The present work investigates the influence of milling and calcination atmosphere on the thermal decomposition of SrTiO3 powder precursors. Both pure and neodymium-modified SrTiO3 samples were studied. Milling did not ...
Completeness of beta-phase decomposition reaction in Cu-Al-Ag alloys
(Springer, 2012-08-01)
The completeness of beta-phase decomposition reaction in the Cu-11wt%Al-xwt%Ag alloys (x = 0, 1, 2, and 3) was studied using differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and optical microscopy (OM). ...
Influence of Cu and Cr on the matrix decomposition of quenched Al-Zn-Mg alloy
(Akademie Verlag Gmbh, 1991-03-01)
The Inoue procedure is used to study the influence of Cr and Cu elements, jointly or individually, on the matrix decomposition of quenched Al-Zn-Mg alloys. The addition of copper and copper with chromium does not significantly ...
Thermal decomposition kinetics of Brazilian limestones: effect of CO2 partial pressure
(TAYLOR & FRANCIS LTDABINGDON, 2012)
The influence of the partial pressure of carbon dioxide (CO2) on the thermal decomposition process of a calcite (CI) and a dolomite (DP) is investigated in this paper using a thermogravimetric analyser. The tests were ...
Decomposition and nutrient dynamic of leaf litter and roots from palatable and unpalatable grasses in a semi-arid grassland
(Elsevier Science, 2001-09)
A field experiment was conducted in a temperate semi-arid grassland of central Argentina to test the hypothesis that decomposition of and nutrient release from leaf litter and roots are faster in Poa ligularis and Stipa ...
Combinatorics of binomial primary decomposition
(Springer, 2010-04)
An explicit lattice point realization is provided for the primary components of an arbitrary binomial ideal in characteristic zero. This decomposition is derived from a characteristic-free combinatorial description of ...
Polar decomposition of oblique projections
(Elsevier Science Inc., 2010-10)
The partial isometries and the positive semidefinite operators which appear as factors of polar decompositions of bounded linear idempotent operators in a Hilbert space are characterized.
