… Bioenergi AS an example of thepossibilities and limitations of a secondary low temperature district heating system. Focus areas arepast and present limitations of plastic pipes and on what temperatures may be used when taking intoconsideration the potential for growth of …
… from start. Physiological parameters (blood pressure, heart frequency and skin temperature) and behaviour/emotional status were registered on horses and humans before and after 2 and 4 minutes after the active treatment and 15, 25 and 45 minutes after the active treatment …
… catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions …

… hours then examined the definition of thermal comfort based on the operating temperature drop that occurs during heating off. The results of the three simulations showed that rapid temperature drops occurs during the first hour, and then a slower decline in temperature over …
Kan man med hjälp av lagrad värme undvika att de uppstår i betonghus?
… hours then examined the definition of thermal comfort based on the operating temperature drop that occurs during heating off. The results of the three simulations showed that rapid temperature drops occurs during the first hour, and then a slower decline in temperature over …
… geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that …
… between Normalised Difference Vegetation Index (NDVI) and radiative surface temperature. A main goal for most studies have been to find the best method for carrying out land cover classifications and to study land cover changes, based on a combination between the two parameters …
… Bioett AB. Problem: How does the distribution of cut flower works regarding temperature, losses, responsibility, complaints, packaging and weak points? Purpose: The purpose is to map the distribution of cut flowers, with focus on losses in the temperature, from farm to store …
… thesis a rough description of aluminium extrusion is made, the importance of temperature of both the raw material and the extruded profile for a good profile quality. The difficulty in controlling these temperatures are discussed and attempts to increase the control are …
… amounts of insulation have been studied for the effect of differences in air temperature, outside the cottage compared to the inside of the hut, ?T. Roof heights between 400 mm and 700 mm have been studied. Roof heights about 700 mm is a common height for the huts that are …
… was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute …
… further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the …
… is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature. In Chapter 3 and 4 …
… becomes. The most important factors are the amount of urea being used and the temperature of the flue gases where the reaction with urea takes place. A model with these two factors as inputs and the content of nitrogen oxides as output is derived. This is done with experiments …
