The Sikora buffer does not mimic the adapted SMP buffer used in Southern Brazil, since the former has a low ability to distinguish soils with different acidity from each other, probably due to the higher buffer capacity than of the adapted SMP solution.SAMIEBilibogr...

Proton and 11 B magnetic resonance studies of the redistribution in the system BR 3 /BT 3 (R = C 3 H 7 , T = OCH 3 , SCH 3 and N(CH 3 ) 2 ) show that equilibria between different species BR n T 3– n ( n = 0, 1, 2, 3) occur. In general it appears that the ...
We have measured the coefficient of viscosityBat 25 °C of HCl, LiCl, NaCl, KCl, RbCl, KI, and KBr in the mixtures of aqueous organic solvents containing from 10 to 40%tert-butyl alcohol by weight (X), the concentration of electrolyte varying from 0.1 to 0.3 M.Plots ofB = f...
Moreover, this method is able to give indications of the life time on different sites. We also give an evaluation of the limits of the method.S. CombrissonB. RoquesP. RignyJ. J. Basseliercanadian journal of chemistry
A cluster is equivalent to a virtual tone, carrying 2 bits of information and ensuring the mandatory bit error rate. By this simple tones aggregation the unused DMT capacity can be reduced up to 75%.Pierrugues, LaurentBibliogr

Finally, we consider continuous models, and more specifically a class of differential systems based on power-Iaws, known as S-systems. Within this framework, we present an iterative algorithm that finds positive equilibria of any dynamical system, giving at the same time a local power-Iaw ...
In part I (this Bulletin 80 (1971) 91-105) the binary systems As-Fe, As-Co and As-Ni were considered. The ternary systems As-Fe-Co and As-Co-Ni, as obtainable by thermal synthesis at 700° or by precipitation with AsH 3 , are now studied. The composition range covered is MeAs ...
