The problem of engines in statistical physics
(2021-08-22)
Engines are open systems that can generate work cyclically at the expense of an external disequilibrium. They are ubiquitous in nature and technology, but the course of mathematical physics over the last 300 years has ...
Effects of drying/rewetting on soil aggregate dynamics and implications for organic matter turnover
(Springer, 2020)
Drying and rewetting (D/W) of soil have significant impacts on soil organic matter (SOM) turnover. We hypothesised that frequent D/W cycles would release the labile organic matter locked away in soil aggregates, increasing ...
Leaking elastic capacitor as model for active matter
(2021-05-24)
We introduce the “leaking elastic capacitor” (LEC) model, a nonconservative dynamical system that combines simple electrical and mechanical degrees of freedom. We show that an LEC connected to an external voltage source ...
Tidal time-scale variation of inorganic nutrients and organic matter in Bahia Blanca mesotidal estuary, Argentina
(Taylor & Francis, 2009-12)
Land-derived materials are regulated by coastal and shelf environmental conditions before being transported to the open sea. It is of great concern to understand the processes and to establish the extent in which they ...
Organic matter-phosphorus associations as a sink in P-fixation processes in allophanic soils of Chile
(Pergamon Press Ltd, 1983)
In fertilized and unfertilized plots of ten Chilean allophanic soils the fraction of total-P associated with organic matter and the organic carbon content were determined. Cultivation with P fertilization for 40 yr or ...
Effects of stratospheric ozone depletion, solar UV radiation, and climate change on biogeochemical cycling: interactions and feedbacks
(Royal Society of Chemistry, 2015-01)
Climate change modulates the effects of solar UV radiation on biogeochemical cycles in terrestrial and aquatic ecosystems, particularly for carbon cycling, resulting in UV-mediated positive or negative feedbacks on climate. ...
