Maintaining energy balance is a challenge shared by all animals which has resulted in an enormous variety of strategies for maintaining this vital balance. One of these is torpor, a mechanism that slows down basic metabolic rate (BMR) which results in a low expenditure of energy otherwise used to maintain …

With increasing world population, more wastewater is produced which all need purification treatment. Removal of pathogenic organisms is important because they can cause problems to human health. This experiment will focus on the removal of human bacterial pathogens. The problem of human bacterial pathogens …

A study on the synthesis and emulsification of alkyd resins was performed in order to find relationships between the vistocisty, molecular weight and oil length. The emulsions were used to study the effect of the viscosity and oil length on the gloss of waterborne alkyd paints. An empyrical relationship …

The aim for this thesis is to set up and develop electroplating technique for depositing gold layers. This gold layer will be used as an thermalisation layer in a cryogenically cooled X-ray detector. Key material parameter for the gold layer is a low thermal resistivity at cryogenic temperatures. Since …

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …

With the increase of offshore activities in the Arctic, the question arises if currently existing oil spill response plans involve effective methods for removing oil slicks in Arctic conditions. The dispersant Corexit9500 is commonly applied as response agent to disperse oil slicks. It has been applied …

The effect of an elevated sample temperature on the growth rate of carbon in the holes of a Multiple Aperture Array (MAA) has been examined. The loss of transmitted electrons through the MAA was measured by taking pictures with a camera of an Yttrium Aluminum Garnet (YAG) scintillation crystal. The growth …

Lyme borreliosis, commonly known as Lyme disease, is a vector-borne disease that is caused by the bacterium Borrelia burgdorferi sensu lato. Infected ticks can transmit this disease and infect humans. Decreasing human Lyme infections could be achieved by vegetation control , since mortality and questing …

Turbine blade cooling has been a topic of significant interest, as increasing turbine entry temperatures result in higher cooling requirements. The present numerical method divides the blade into a finite number of elements in the span and peripheral directions and solves the heat transfer fundamental …

This thesis describes how the abundance of CO2 a ects the porosity of H2O:CO2 ice mixtures deposited at di erent growth temperatures ranging from 30 - 70 K. The mixing ratios of the used ice samples H2O:CO2 = 10:1, 4:1 and 2:1 are of astrophysical relevance. Laser optical interference is used to monitor …
