In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.

A study of southern pudu (Pudu puda) was performed at the zoo Nordens Ark in Bohuslän, Sweden during twelve days in Mars and April 2014. Observations were performed during twilight. Time budget and enclosure use was examined, when the animals had access to the whole enclosure of 1000 m2 or a smaller part of the enclosure of 200 m2. There was almost no difference in time budget between the two enclosure sizes. At both enclosure sizes the animals spent most of the time at a place that was hidden from outside the enclosure. The hidden place was situated in the house.

Camera surveillance can provide good protection against certain types of crime, but it can also invade our privacy. The County Administrative Board monitors compliance with the rules by visiting those places to which the general public has access. They have to issue permits before general camera surveillance to those places which the general public has access. In certain cases, in stores for example, general camera surveillance is permitted only if the Country Administrative Board is notified in advance. The Data Inspection Board is a public authority and responsible for the camera surveillance for those places to which the public not has access.

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

BCFP (BarnCancerFöreningsProgrammet) är ett verktyg som ska användas till att hantera information om insamlingsbössor samt kringliggande information åt Barncancerföreningen Norra. Tidigare användes Microsoft Excel för att hantera dessa uppgifter. Detta var inte en långsiktigt hållbar lösning därför att informationen inte går att överblicka och önskvärd information är svår att hitta. Det finns också en annan lösning utvecklad i Microsoft Access men denna lösning var inte anpassad till Norra föreningens behov och skulle vara tidskrävande att vidareutveckla/omarbeta. Detta medförde att målet med det här projektet blev att ta fram ett nytt system för hantering av ovanstående uppgifter.

The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.

SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.

Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time. I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

This Master's thesis aims at pinpointing the political arguments that appear in the recent debate on scientific publication. There is a widely spread opinion that prices on digital resources are far too high, thus taking up a major part of the University libraries budget, while publishing companies make high profits. It is also a common opinion that the current publishing method does not take full advantage of the possibilities of electronic publishing. Lately a number of alternative ways of publishing have been initiated and discussed, generally referred to as open access. Open access published material is available free of charge and free of most copyright and licensing restrictions on the public internet.In this thesis the minutes from four hearings held by the UK House of Commons in the spring of 2004 are examined.

This report is presenting an approach that can be used to measure water surfaces in difficult conditions caused by dense vegetation and lack of nearby known points. The objective was to make a contribution to necessary measures for adaptation against floods in Grums Municipality along the stream Karlbergsån, which may occur when persistent rain raises the level of the stream. Along the river there are low-lying areas prone to flooding. According to Grums Municipality, the stream may widen where the water level differences are large, to create a better flow path and to counteract flooding. Grums Municipality was also interested in survey stormwater discharges which may affect the water level in the stream.

Being able to know how use the rules about how taxes works, allows a shareholder with qualified holding in a closely held company, to pay less taxes. When the owner of the share makes an agreement, which the ownership rights transfers later than the actual date for when legal contract is written. The question is therefore who can consider being the new owner at the beginning of the year and taking part of the benefits. Do the ownership rights transfer on the contract date or the date of access?When a buyer purchase a share during the year, he may not partake of any threshold amount, then the expected time is for those who are owners at the beginning of the year.
