… det trycket där högst effekt kan erhållas från expandern, är beroende av EGR temperaturen. Det innebär att ju högre EGR inloppstemperatur desto högre optimalt ångtryck. EGR temperaturen i punkt 2 i ESC cykeln är 514? C för denna motor, vilket resulterar i ett optimalt tryck på …
… Den viktigaste faktorn för att kunna påverka bakterietillväxt i livsmedel är temperatur. Livsmedelslagstiftningen har inga temperaturkriterier, det är livsmedelsföretagarens ansvar att ingen hälsofara ska kunna uppstå på grund av livsmedel. Hygienkonsulter har sedan tolkat …
Förstudie av förutsättningar för, - och lönsamhet med, solfångare för att värma terapibadet
… heated by a radiator circuit that is being heated by the district heating. The temperature in this circuit is however controlled by the outside temperature. If the outside temperature is increased sufficiently, there is no need to heat the building with the radiators. What …
… electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been …
… the width of the tree rings, a chronology that is representative for July temperature is made over this area. The method is called dendroclimatology and has generally been used to reconstruct past climate for the last 1000 years. The results of this study show that the tree ring …
… is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling …
en studie av trädens effekt på en bostadsgård i Malmö
… introducerats som absorberar värme från solens strålar och höjer stadens temperaturer. Dessa material leder även snabbt bort regnvatten samt hindrar vatten att infiltreras ner i marken. Temperaturskillnader på 12oC jämfört med den omkringliggande landsbygden har kunnat uppmätas …
… there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The …
With climate change, the temperature and relative humidity in Sweden are increasing. The majority of historical environments lack protection against this increase, which also increases the risk of mold infestation in these environments. One of these environments is N??s Slott …
… that have caused climate change. A marine heatwave is when the sea surface temperature rises, which damage many different ecosystems in the sea. One ecosystem that is sensitive to temperature changes is tropical coral reefs, which are at risk of bleaching during marine …
… 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 …
… 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 …
Kan dess förändringar förklaras av funda-mentala faktorer?
… i denna uppsats är priset på utsläppsrätter, nettoexport till Tysk-land, temperatur, nederbörd, priset på kol och villaolja samt konjunkturutveckling i Sve-rige. Undersökningen av faktorerna bestod av en multipel regressionsanalys med undersökta faktorer som oberoende variabler …
