Spatial analysis, playing an essential role in data mining, is applied in a considerable number of fields. It is because of its broad applicability that dealing with the interdisciplinary issues is becoming more prevalent. It aims at exploring the underlying patterns of the data. In this project, we will employ the methodology that we utilize to tackle spatial problems to investigate how the cell

Jakten på fisken i Ringsjön Många vill veta var i sjön fisken finns när man ska fiska och nu finns det en teori som berättar hur fisken sprider ut sig i en sjö. Fiskar sprider ut sig så att områden med mer resurser har fler individer jämfört med delar med mindre resurser. Detta gör att det finns mer individer som konkurrerar om mat i resursrika områden medan i områden där det är svårare att hittaMovements occur among many different organisms and a suggested theory about the pattern of these movements is called the Ideal free distribution. It states that individuals in a complex area with different quality of the habitats will distribute themselves proportionally after resources in the different habitats, so that they can maximize their fitness. Lake Ringsjön is a complex lake, which consi

Surface coatings are used in many applications. An advantage of coating a surface using particles from a dispersion is that a change in, for example, temperature can control the compactness of the surface coverage. In this research the competition between bulk aggregation and surface adsorption of colloidal silica spheres was investigated. The system used contained aqueous dispersions of industria

This master thesis aims to gain an understanding about how managers and members in an organization perceive observed employee silence (intentional withholding ideas at work) and attribute meanings to it. In addition, it aims to reveal, in what situations observers are not able to identify the intentional silence. Organizational culture, sensemaking and power relations and U-turn in criticism are t

This essay's primary purpose is to find out if there are any typical features that can be seen in the expensive homes belonging to the upper class. What makes these homes feel specifically luxurious? Is there something we can call "luxury" that is timeless? I have analysed two interiors from two different eras, both inhabited by the upper class. The concept of luxury and "good

Abstract Bacteria exist everywhere, some of which are harmful to humans. To prevent spread of diseases and contaminants, handling, preparation and production of food are strictly regulated. In the geriatric care, food is served to very sensitive people with diseases or weak health and therefore it is very important that food and hygiene standards are high. In the municipality of Kävlinge some sho

Anaerobic digestion is widely used for the treatment of industrial wastewater for its cost benefits effects and potential production of renewable energy. Therefore, industries/industrial plants are installing and developing their wastewater treatment plant with this method for treating the discharged wastewater to get renewable energy source for the production of heat and electricity. To investiga

In the recent decades, one of the most phenomenal changes in many universities in Western countries is the dramatically increase of students from China. Subsequently, the thesis author mentioned that general view concerning educational tourism associates educational tourists with the international students’ mobility. This has emerged as an important part of the university students’tourism market.

The nitrification process is known to be the most sensitive link in biological nitrogen removal used in many wastewater treatment plants. Many different inhibitory substances can disturb these sensitive bacteria and in that way cause reduced nitrogen removal. The aim of this study was to investigate the nitrification inhibition in a laundry wastewater before and after internal chemical treatment.

Populärvetenskaplig sammanfattning: Hur ska vi fiska torsk i Öresund? Debatten om man ska fiska torsk i Sverige och i så fall hur har pågått under en längre tid. Detta för att torsken har minskat kraftigt efter år av överfiske. I Öresund har torskbeståndet dock klarat sig bättre, då trålfiske i sundet är förbjudet för sjöfartens skull. Här är torsken även ganska stor jämfört med övriga ÖstersjönThe objective of this study was to analyze recreational and commercial fishing and their respective effect on revenue and catches in the cod fishery in Öresund. This was done by including both recreational and commercial fishing in a bio-economic model. The results from the bio-economic model suggest that more fishing effort is being put in on the cod stock than what is most cost effective, by bot

Populärvetenskaplig sammanfattning: Kartläggning av långbensgroda på Öland Amfibier världen över har minskat kraftigt sedan1970-talet. Orsakerna är många men flera är okända. Fem av tretton amfibier i Sverige är hotade och åtgärder genomförs för att öka arters populationer. Biogeografisk uppföljning är ett nationellt program för uppföljning av amfibier som kan upptäcka förändringar i en arts popAs a result of e.g. habitat loss and diseases, a global decline of amphibians is a fact. In order to prevent further declines and to improve the conservation status for amphibians in Europe, the member states have to report the status for amphibians every sixth year to EU. In Sweden, the County Administrative Board in Scania is responsible for coordinating the biogeographic monitoring of amphibian

Syftet med denna rapport är att granska och utvärdera den praxis som finns idag i fråga om hur kommuner hanterar anslutning av industrier och verksamheter till det kommunala, REVAQ-certifierade reningsverket. Anledningen till detta är att det slam som uppstår vid rening av avloppsvatten har ett högt innehåll av närsalter. Detta innebär att slammet kan nytt-jas som gödningsmedel, förutsatt att det

The aim of this thesis is to investigate double taxation treaties impact on intermediate trade. Based on a panel data sample of five partner countries and 39 reporter countries over the period 1990-2012, the impact of signing DTTs on imports of intermediate trade in goods between two countries is analysed through a Gravity model. The main results show that DTT signing is associated with an increas

Agricultural intensification and its effect on spiders and their prey Spiders are abundant predators that can be very useful for biological control, as they eat insects that can damage crops. To study the potential of this group as biocontrol agents it is necessary to understand the trophic relationships and the factors that affect the distribution of both spiders and their prey. For this purpos

Cyanobacteria possess unique and exciting features among photosynthetic microorganisms for energy conversion applications. This thesis project focuses on conversion of solar energy into photocurrent generation comparing three different strains of Cyanobacteria, Leptolyngbia sp. from New Zealand (CYN82), Leptolyngbia sp. from Antarctica (CYN65), Chroococcales sp. from Antarctica (CYN67) and one euk

Development of environmentally friendly and cost-efficient energy sources has been a challenge for modern society since long ago. Sunlight is an infinite and costless source of energy on Earth, so it would be an enormous advantage to efficiently harvest and transform it into electrical energy used in our everyday life. In nature the process, which converts light energy into chemical energy, is cal

Dye sensitized solar cells (DSSCs) recently attracted much attention as a relatively efficient and inexpensive light-to-electricity energy conversion solution. So far the best performing DSSC devices were produced employing ruthenium (RuII) complexes as the active material, nevertheless limited resources of this metal initiated the research of new alternatives. Iron is one of the most abundant ele

This thesis aims to investigate the electrical properties of the organic charge transfer complex Tetrathiafulvalene-7,7,8,8-Tetracyanoquinodimethane, TTF-TCNQ. This is done through two different experimental techniques: Hall characterization and terahertz measurements. Before performing the experiments, suitable devices for these techniques were designed and produced. The layer of TTF-TCNQ was eva
