… utlovades ger spillvärmen inte den utlovade effekten. Det är främst den högre temperaturen in i växlaren som bidrar till den lägre effekten. Ingående vattentemperatur, d.v.s. returtemperaturen från fjärrvärmenätet, är ca 50°C istället för utlovade 40°C. Vidare är heller inte …
… fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate. In this thesis work, the …
situationen i Sverige och effekter av utetemperaturen. Enkätundersökning och experimentell studie
… and the relevant legislation and, finally, to study how changes in the air temperature and air composition in the car affect the dog. The project consisted of a survey of the literature, a questionnaire part and an experimental part. An important conclusion is the importance of …
… to isolate the faults. The linear state space model is used to estimate the temperature right behind the engine turbines. This is a state space model with two states. This model estimates the temperature well at higher throttle levels, but has a temperature discrepancy of almost …
… if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of …
en åtgärd för ökad TOC-reduktion hos Skoghalls Bruk luftade damm
… This seasonal variation can to a large extent be explained by, that the water temperature in the lagoon decreases wintertime. The low water temperature does that the biological activity in the lagoon is reduced, which reduces the TOC-reduction. A second reason can also be that …
… current which develops heat from battery to glove through a circuit. The temperature is between 32 and 34 degrees. The problem with the existing circuit was to regulate the temperature. There is only on/off switch and there is no way to adjust desirable value of the temperature …
… suitable method to reach and attain a hygienically safe product. Three time-temperature proportions were tested, 55, 70 and 80°C. The results show that a raise in temperature lead to a change in the composition of the dried biowaste, most distinctively for the highest …
… consumption. As a result of increasing engine power, the engine and coolant temperature increases as well due to insufficient cooling performance (because of design issues, cost etc.). Also, emission legislations, both current and future, require more and more measures to be …
… på marknaden. Att egenskaperna hos virke förändras då det utsätts för höga temperaturer har varit känt länge och flera metoder för värmebehandling har utvecklats och industrialiserats. I Sverige har dock värmebehandlat virke inte slagit igenom på marknaden i någon större grad …
… juice. During the project it was found that it is difficult to reach thewanted temperature of above 100°C, when the steam is generated under pressure. When thesteam was released in normal pressure, a decrease in temperature occurred that were so largethat the steam had a …
… hypothermia during general anaesthesia are many and varied. The lowered body temperature causes negative physiological effects and leads to discomfort for the animal during the recovery period. This student report is a combination of field study and literature review. In the …
… that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved …
