The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. Therefore it is of great importance to predict the consequences that can appear in the surroundings due to a declining groundwater surface.The aim of the study was to investigate different methods for predicting leakage and changes in groundwater level due to tunnelling excavations in rock. This thesis was performed by comparing mathematical methods, actual groundwater changes and results from preliminary investigations.Investigations were made for three railway tunnels planned by Botniabanan AB.

Kadmiumkällor och risker med exponering för kadmium beskrivs. Svenska nationella och Stockholms kommunala miljömål som rör kadmium gås igenom och analyseras ur olika aspekter. Två olika modeller för flödesanalyser beskrivs och jämförs. Beräkningar för kadmiumflöden i Stockholm 1995 genomförs enligt den ena flödesmodellen. Beräkningarna redovisas i ett Microsoft Excelark tillsammans med några enkla analysverktyg.

På Riddarholmen idag finns ett mycket begränsat utbud på publikt tillgängliga byggnader. Tots ett centralt läge och en attraktiv kulturmiljö, är det få Stockholmare som hittar till ön. Genom att bygga ett Musikens hus för amatörmusik intill Riddarholmskyrkan, förbättras Riddarholmens publika miljö, samtidigt som det skapas en god plattform för amatörmusiken i Stockholm. Satsas det idag på den marginaliserade amatörmusiken, ges förutsättningar för att i morgon ha en livskraftig och kompetent muikscen i Stockholm..

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm.

Urban planning is not only a matter of architectural trends; it is first and foremost political. This thesis seeks to understand the links between political ideas and visions for the city and the physical structure of the city. The study aims to construct a model to help understand these links, a helpful tool in analysing a city, focusing on the one hand at the physical structure of what I call "The City as a Welfare Provider" and on the other hand at "The City as a Growth Engine". It also sets out to test this model in an empirical study of Stockholm and the soon-to-be built district of Norra Station in the same city.The analysis shows that Stockholm has ambitions to be a welfare provider to its citizens, but have also adopted to a discourse of interurban competition which stresses the importance for the city to enhance economical growth. What is interesting is that the physical structures promoted in the planning documents of Stockholm are nearly exclusively those associated with the model of "The City as a Growth Engine"..

In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

Purpose: The aim of this paper is to investigate whether there are differences between big cities and small cities in adventure tourism. The cities that are studied are Stockholm and Visby.Methodology: The study is based on a qualitative method. We have done interviews and observation. We also used books and internet when collecting information.        Conclusions: The study has shown that differences exist between large and small cities. People seek out the opposite, whether you're from a big city or small town.

In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Uppsatsens syfte är att problemidentifiera hur en musikfestival, som drivs ideellt jobbar med organisation, information och kommunikation för att överleva.För att kunna ta reda på vad en festival kan göra för att överleva valde jag en deduktiv ansats. Teorin har sedan jämförts med fallstudien Arvikafestivalen. Förutom respondenternas reflektioner kommer även mina reflektioner redovisas då jag har varit observerande deltagare under Arvikafestivalen 2009 och 2010.Kommunikation är en viktig faktor vid planering av ett evenemang. Det måste finnas en tydlig kommunikation till intressenterna, funktionärerna och även inom ledningen. Att ha en välgenomtänkt planering är även viktigt.

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.
