The objective of this study was the detection and assessment of nutrient entry pathways in a complex mesoscale lowland catchment. The central aim was the development of a transferable method for an efficient estimation of instream water quality in rural environments. The investigated Kielstau catchment with a size of approximately 50 km2 is located in the North German lowlands. Land use is domi...

Control of balance is complex and involves maintaining postures, facilitating movement, and recovering equilibrium. Balance control consists of controlling the body center of mass over its limits of stability. Clinical balance assessment can help to assess fall risk and/or determine the underlying reasons for balance disorders. Most functional balance assessment scales assess fall risk and the ...

Comparative analysis of trophic networks was carried out to evaluate environmental management actions aimed at countering an environmental crisis in Orbetello Lagoon, Italy. Two mass-balance models of this shallow water coastal system were constructed, for 1995 and 1996. During this period, there was an observed change in the composition of the submerged vegetation that indicated a significant ...

Total body water and tonicity is tightly regulated by renal action of antidiuretic hormone (ADH), reninangiotensin-aldosterone system, norepinephrine and by the thirst mechanism. Abnormalities in water balance are manifested as sodium disturbances--hyponatremia and hypernatremia. Hyponatremia ([Na+ < 136 meq/ l]) is a common abnormality in hospitalized patients and is associated with increased ...

This paper addresses the current imperative to develop and test urban ET algorithms, incorporate these into urban water balance models, and develop these into tools to underpin and guide Water Sensitive Urban Design (WSUD) and integrated urban water management. Two approaches to modelling the urban water balance focusing specifically on urban evapotranspiration are presented: i) SUES (Single-so...

Possible cleaner production (CP) opportunities for a milk processing facility were examined in this study. The CP concept and its key tools of implementation were used to assess the potential CP opportunities in the facility studied. The general production process and its resulting environmental loads were investigated by taking possible CP opportunities as the basis of study. The methodology d...

Classical homogeneous nucleation theory is extended to nonisothermal conditions through simultaneous cluster mass and energy balances. The transient nucleation of water vapor following a sudden increase in saturation ratio is studied by numerically solving the coupled mass and energy balance equations. The ultimate steady state nucleation rate, considering nonisothermal effects, is found to be ...

Assessing the future effects of climate change on water availability requires an understanding of how precipitation and evapotranspiration rates will respond to changes in atmospheric forcing. Use of simplified hydrological models is required because of lack of meteorological forcings with the high space and time resolutions required to model hydrological processes in mountains river basins, an...
