[1] Estimates of mean residence time (MRT) are increasingly used as simple summary descriptors of the hydrological processes involving storage and mixing of water within catchment systems. Current understanding of the physical controls on MRT remains limited, and various hypotheses have been proposed to explain its variability between catchments. We present a series of virtual experiments to in...

Evaluating biochars for their persistence in soil under field conditions is an important step towards their implementation for carbon sequestration. Current evaluations might be biased because the vast majority of studies are short-term laboratory incubations of biochars produced in laboratory-scale pyrolyzers. Here our objective was to investigate the stability of a biochar produced with a med...

Pyrogenic carbon (PyC) is an important component of the global soil carbon (C) pool, but its fate, persistence, and loss dynamics in contrasting soils and environments under planted field conditions are poorly understood. To fill this knowledge gap, a 13C-labelled biochar, as a surrogate material for PyC, produced from Eucalyptus saligna by slow pyrolysis (450°C; δ13C -36.7‰) was surface (0-10 ...

All academic disciplines include research, and students in research programmes should have a solid understanding about basic principles. Owing to generate perfect graduate, postgraduate teachers must guarantee that gain the ability do using recognised procedures connected with specific educational sub-disciplines. Many factors may affect attitude of college students. A deep probe on location le...

This paper investigates the determinants of female autonomy in Indonesia using the 2000 Indonesian Family Life Survey (IFLS3). We consider the role of kinship norms and the effect of labor force participation on female autonomy. Our measure of autonomy is based on self-reported answers to an array of questions relating to decision making authority in the household. They include economic and chi...
