The trophic evolution of Lake Iseo as related to its holomixis
Journal of Limnology, 1999 Lake Iseo is undergoing a progressive deterioration in water quality, mainly due to eutrophication. This paper, based on measurements performed on the main tributaries and the outflow, considers the phosphorus, nitrogen and silica budget of the lake ...

Effects of Soil, Light, and Temperature on Freshwater Tannin Concentrations
HydrobiologyTannins are plant secondary compounds that leach into soil and water. Tannin concentrations can be higher in lentic freshwater than in other aquatic ecosystems, which can result in toxicity to freshwater organisms.

Interstellar water chemistry: from laboratory to observations
, 2013 Water is observed throughout the universe, from diffuse interstellar clouds to protoplanetary disks around young stars, and from comets in our own solar system and exoplanetary atmospheres to galaxies at high redshifts.

Fens of the Sierra Nevada, California, USA: patterns of distribution and vegetation [PDF]
Mires and Peat, 2015 A broad sample of 79 montane fens in the Sierra Nevada revealed that underlying geology and topography exert strong control over the distribution and vegetation of these ecosystems.

Water Treatment Without Chemistry
CHIMIA, 2003 Thin-film boron-doped diamond coatings (BDD/Si) on boron-doped silicon substrates by means of a large-scale hot-filament chemical vapor deposition (HF CVD) process have been developed in order to be used as an innovative and efficient electrode ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

A Geothermal Plant from a Time-Scale Perspective
Energies, 2021 In recent years, geothermal energy use from low-temperature sandstone reservoirs has sharply increased. Nonetheless, the injection of heat-depleted geothermal fluids has not been an easy task because of well/formation damage and operational/economic ...

Forest influence on the surface water chemistry of granitic basins receiving acid precipitation in the Vosges massif, France [PDF]
, 1987 This study shows the influence of acid rain on the chemistry of surface waters in two small basins. The basins present similar altitudes and climates, only one is forested, and the forest decline has been clearly established.
