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 …
… reda på om det finns en skillnad mellan olika fibervävar och deras effekt på temperatur, luftfuktighet och klimatet under fibervävarna. Försöken är tänkt att utgå från de förhållanden som finns i kulturodlingar av färskpotatis och jordgubbar för att se vilken effekt fibervävarna …
… 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 …
… 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 …
… 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 …
En ändrad styrning av framtemperaturen
… district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers. Typically, the forward temperature is …
… and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate …
… is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish. Cultivated smolt is today bigger than it was before, it is also bigger …
… Syftet med det här examensarbetet var att undersöka hur begreppen värme och temperatur framställs i svenska gymnasieskolans läroböcker och att med utgångspunkt i vanligt förekommande felaktiga föreställningar om värme och temperatur, undersöka om det finns grogrund för dessa …
… types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery …
Investigation of bondning mechanisms at the pressing of metal laminates
… The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure. The materials have been pressed at room temperature or heated in an …
