The photodegradation of isoproturon (IP) was performed using TiO2 supported on glass rings in a 1.5 l coaxial rector. After 60 min of phototreatment, IP was completely eliminated and about 80% of dissolved organic carbon (DOC) remained in solution. This ef ...
Global data sets of the stable carbon isotope composition of plant leaves, of CO2 in canopy air, and of CO2 in the background atmosphere were compiled and compared to results of a global vegetation model (BIOME4) that simulated, at these three scales, the ...
The terrestrial biosphere model Carbon Assimilation in the Biosphere (CARAIB) was improved by introducing two vegetation storeys and implementing a new module which simulates the equilibrium distribution of the vegetation inferred from physiological proces ...
The photocatalyst for the use in the production of hydrogen from water or aqueous solutions of organic compounds by using light energy, comprises carbon, in addition to a semiconducting photocatalytic material. The photocatalytic apparatus for the producti ...

Sustainable management of natural water resources should include environmentally sound dam construction and operation with respect to both upstream and downstream management, Because of slowly evolving alterations in riverine ecosystems following the const ...
The concurrent effects of increasing atmospheric CO2 concentration, climate variability, and cropland establishment and abandonment on terrestrial carbon storage between 1920 and 1992 were assessed using a standard simulation protocol with four process-bas ...
5-amino-6-methyl-2-benzimidazolone (AMBI), used in the manufacture of dyes, was characterised as a biorecalcitrant compound by means of different biodegradability tests. In order to enhance the biodegradability of this important pollutant, the application ...
We analyzed seasonally aggregated observations of temperature, conductivity, dissolved oxygen and dissolved inorganic carbon from Soppensee (District of Lucerne, Switzerland) for the yrs 1980 to 1993. Holomictic Soppensee is characterized by a strong summe ...
This paper focuses on the impact of an oscillating low-speed current on the structure and dynamics of the bottom-boundary layer (BBL) in a small stratified basin. A set of high-resolution current profile measurements in combination with temperature-microst ...
The goal of this paper is to put the issue of preserving Soil Organic Matter (SOM) into a regional, urban-rural, context. In doing so, we apply the method of material flux analysis to a watershed in Boyacá in Colombia. We estimate the order of magnitude of ...
