The effect of Ferralsol mineralogy on the distribution of organic C across aggregate size fractions under native vegetation and no-tillage agriculture
(2017-06-01)
No-tillage management can increase soil surface layer organic C (OC) levels compared with conventional tillage. The mechanisms underlying this increase in highly weathered tropical soils, such as Ferralsols, are not well ...
Sodium dodecyl sulfate (SDS) effect on the thermal stability of oxy-HbGp: Dynamic light scattering (DLS) and small angle X-ray scattering (SAXS) studies
(2013-11-01)
Glossoscolex paulistus (HbGp) hemoglobin is an oligomeric protein, presenting a quaternary structure constituted by 144 globin and 36 non-globin chains (named linkers) with a total molecular mass of 3.6MDa. SDS effects on ...

Constitutive theory for Recycled Aggregate Concretes subjected to high temperature
(Elsevier, 2016-05)
The use of recycled aggregates in concrete to partially substitute the natural ones has strongly increased in the last decades. Due to both, environmental and economical reasons, a relevant and increasing proportion of the ...
