… solvents are mobile in soils. Chlorinated solvents can be harmful at low concentrations. Complete degradation can only occur under specific conditions. Because of the properties of these substances, investigation and analysis methodology are extra important for determining …
… of halogenated substances (AOX) and the heavy metals nickel and copper. High concentrations of contaminants were reduced better than low concentrations in the two treatment steps. The carbon and peat filter material also caused an increase of the arsenic content in the leachate …
påverkande faktorer och metodik för statistisk modellering
… variance of the residence time distribution, the hydraulic efficiency and the concentration of incoming metals and suspended solids. The specific pond area is a factor which is defined as the pond area divided by the reduced run off area. The results from the multiple regression …
… with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine. An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly. The …
… user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent. Carbon dioxide is fed into the system from a tank by a mass flow regulator. The supply of carbon dioxide can be set according to a constant flow to simulate a …
… A modification of the model was made in order to handle changes in agent concentration. The carbon dioxide production was implemented by dosing carbon dioxide from a gas tank through a mass flow controller. The carbon dioxide in the system can be set to a constant flow to …
… agreed that ideas develop from consistent practicing. Consistent practicing, concentration and purposefulness are some of the keys with which the informants find the positive spiral. It requires a balance in practicing between fixed goals that are both short-term and long-term …
-En idrottslärares berättelse om specialgymnastik i skolan
… to theoretical learning exists. Kadesjö describes how difficulties in concentration can arise as a result of problems with mobility and perception, and according to Piaget very young children develop cogitation through physical movements. These connections are not news but …
en studie om sambandet mellan ägandet och utdelningar i Sverige
… in our study show that there is a significant positive relationship with owner concentration and dividends. Comparing to other studies in the field this is a rather controversy conclusion. According to Schooley and Barney (1994) and Farinha (2003) our results confirm the …
… Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles …
… which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow …
… Mechanism which gives a relation to calculate the NO formation rate using the concentration of different gas species involved in the process. All the most important phenomena involved in the Diesel combustion have been modelled. A special attention is then paid to the …
… in this study where we have analyzed plasma estradiol and progesterone concentrations before and after a single intramuscular injection of the GnRH agonist buserelin (Receptal?). The results showed that there is a difference in the response to GnRH stimulation between intact and …
hantering av klimatförändringar och extrema väderhändelser i MKB
… wave radiation in the earth's atmosphere. The problem today is that the global concentration of green house gases has significantly increased since the 1750's as a result of human activity. Today's values widely exceed the preindustrial values. Scientists have established the …
… samples were collected each day before the treatment and analyzed for plasma concentrations of meloxicam, hematocrit, cortisol, progesterone and glucose. We also treated four other kids, born without horns, with meloxicam to analyze the concentration of the drug during six hours …
