rensning av stopp samt uppsamling och attityder
… etc. It was shown that within two years from the installation of the toilets precipitation had accumulated that could block the flow completely. The last study in shis is on methods to clear the blockages. The collected urine solution from Nytorgsgatan contained 2.8 g of …
… using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the …
Strömmars betydelse för lokalisering av odlingslokaler och utformning av kontrollprogram i kustområden
… by factors that are changing during the year such as airpressure, temperature, precipitation etc. Water current measurements can be ofgreat help both when determining how particles from a fish farm is dispersedand also for governing authorities in the processes of both allowing …
… with respect to natural background, variation in time, correlation with precipitation, depth and other measured parameters. Geochemical modelling using the computer code PHREEQC has also been conducted. The waste of the minefields at Gladhammar is constituted of waste rock, slag …
En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
… plating factory inEskilstuna. Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste …
Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
… %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come. The conclusions from this …
… actual need of N is highly affected by current weather such as temperature and precipitation and the strongest correlation value was found in year 2010 (r2=0.68) and the weakest in 2011 (r2=0.26). When the recommendations differ from the actual need they are often too high. In …
… chemical processes in the growing plant. Weather parameters, such as light, precipitation and temperature plays a role for the cadmium uptake. Still, there is relatively limited knowledge about processes contributing to the cadmium uptake and transport in the plant. Through …
påverkande faktorer och metodik för statistisk modellering
Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by …
… The driving data for themodel are 30-year climate data, including data for precipitation, temperature, solar radiation,relative humidity and wind speed, which enables long-term simulations of water andnitrogen flows. Three different simulations were performed, one for present …

Modellutveckling och känslighetsanalys
… parameter, as well as the Kd-value in the embankment, the half-life and the precipitation. As expected, the worst-case analysis showed that a small distance to the groundwater level, a low Kd-value and a short half-life produced even larger concentrations of herbicides in the …
Nederbördsmätning är viktigt inom många områden och en relativt ny teknik är enoptisk distrometer som med hjälp av laserteknik mäter nederbördspartiklarnasdroppstorlek och fallhastighet. Syftet med detta arbete var att undersöka hur välThies distrometer stämmer överens med …
