… 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 …
… 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 …
… som skulle kunna gynnas av denna utveckling då de anses tolerera högre temperaturer än andra växtplankton och modellsimuleringar visar en ökad dominans av cyanobakterier i ett framtida varmare klimat. I denna studie undersöks huruvida tillväxthastigheten vid olika temperaturer …
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 …
… then rubber which can affect the sow’s chance to cool down. Therefore the temperature in the farrowing compartment was measured to see if there was a correlation between the sows lying behaviour and the temperature. In total, the study was performed during five farrowing …
… of the heat exchangers use of energy in Joulin. Even a comparison of temperature efficiencies have been made to see how well the heat recycler is working. To get an economic aspect, the calculation of LCC have been made. This work was in addition to the comparison even to find …

… of the heat exchangers use of energy in Joulin. Even a comparison of temperature efficiencies have been made to see how well the heat recycler is working. To get an economic aspect, the calculation of LCC have been made. This work was in addition to the comparison even to find …
… is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH). Umeå Energi is a district heating company which has noticed these changed customer requirements and are in the need to gain knowledge about the technology of LTDH …
… the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and …
… incoming wastewater can be used in biological phosphorus removal. The sludge temperature, total solids (TS) and retention time are regarded as important parameters for a successful biological phosphorus removal and a laboratory study was set up to investigate these conditions …
… run-time is estimated by measuring the water pipe’s outward vibrations and temperature changes. A test environment was established and a prototype built, using a tilt- and vibration sensor for vibration sensing and a precision temperature sensor to measure temperature changes …
… och motverka ansamlingen av naftalen i tjäroljan gjordes försök att höja temperaturen på naftalenbotten. En höjning av naftalenhalten på fraktioneringskolonnens naftalenavdrag åstadkoms genom en höjning av temperaturen på naftalenbotten. Även en hög temperatur ovan …
… eller vatten ånga till förbränningen åstadkoms genom att sänka den maximala temperaturen i förbränningsrummet och genom att tillsätta inert media med hög värmekapacitet vilket också reducerar syrekoncentrationen. NOx formationen är främst beroende av förbränningstemperaturen men …
… configurations a division of the problem was made, specifically looking at the temperature drop between different parts of the construction as the heat moves from the electronics to the fluid. The maximum effect that the retrofit equipment will lead away is 200W and the air heat …
