Sorption heat engines: simple inanimate negative entropy generators [PDF]
, 2005 The name 'sorption heat engines' is proposed for simple negative entropy generators that are driven by thermal cycling and work on alternating adsorption and desorption. These generators are in general not explicitly recognized as heat engines. Their mechanism is applicable to the fields of engineering, physics, chemistry, geology, and biology, in ...

Fast reaction limit of reaction-diffusion systems [PDF]
arXiv, 2019 Singular limit problems of reaction-diffusion systems have been studied in cases where the effects of the reaction terms are very large compared with those of the other terms. Such problems appear in literature in various fields such as chemistry, ecology, biology, geology and approximation theory.

The Mediterranean deep-sea fauna: historical evolution, bathymetric variations and geographical changes [PDF]
Carnets de G\'{e}ologie / Notebooks on Geology Article 2004/01
(CG2004_A01_CCE-PG) (2004) 10 p., 4 fig., 3 tabl, 2005 The deep-water fauna of the Mediterranean is characterized by an absence of distinctive characteristics and by a relative impoverishment. Both are a result of events after the Messinian salinity crisis (Late Miocene). The three main classes of phenomena involved in producing or recording these effects are analysed and discussed: - Historical ...
