Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel
The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

Matematik och ingenjören : Utveckling av en aktivitet för att öka elevers motivation för matematik
This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.
Miljöarkeologi i Umeå stads hamn och slagfältsarkeologi på Krutbrånet : Två fallstudier inom historisk arkeologi i Umeås 1800-tal
This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.
Kompetensbegreppet i kommunal verksamhet : En kritisk diskursanalys
Large retirement numbers and fierce competition of available labour, results in municipalities have to be more attractive as an employer. One way for the municipalities to fulfil their staffing requirement is partly to increase their recruitment efforts, and partly to educate their existing employees. Discussions about the supply of competence are therefore pressing within municipal activity. The aim of the study was to investigate how the concept of competence is used within a municipal administration. The method that has been used is Norman Fairclough?s critical discourse analysis, a method that allows multi dimensional analysis.
Karaktärisering av hund TK1 för användning som tumörmarkör :
Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.
Undersökningsmetodik för klorerade lösningsmedel i marken
Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.
Television i allmänhetens tjänst : en studie av public service-begreppet
Title: Television in the Service of the Public - a Study of the Public Service Concept(Television i allmänhetens tjänst - en studie av public service-begreppet).Author: Daniel FärnstrandAim: To describe the ideals, or principles, that the Public Service Ideology or concept of Public Service is based upon. The two main questions the paper aims to answer are thus:· Which principles should, according to the theoretical norm, guide Public Service activity?· Which principles guide Public Service television in Sweden today, according to the actual guidelines for the Public Service organization SVT? Method / Material: A study of relevant literature is carried out. Further, the actual guidelines for SVT are summarized. The normative guidelines are then also summarized, and a comparison is made between this summary and the actual guidelines for SVT.Main results: Although a comprehensive definition is hard to find within the theoretical framework, a summary of the theoretical ideal is carried out.
Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige
Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
Statistisk analys av partiella urladdningar
This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.
Vad besökarna gör på ett folkbibliotek. En användarstudie på Borås stadsbibliotek
The purpose of this study was to find out what different groups of visitors do when they are at Borås City Library. Three issues were formulated from the purpose and they were: What do users do when they visit the City Library in Borås? What occupations do those who visit the library have? What similarities and differences are there in the use of the library depending on the visitors? occupations? To answer these questions a questionnaire was handed out among the visitors at Borås City Library. The theory that was used when the material was analyzed comes from the book?Gør biblioteket en forskel?? and the book is written by Henrik Jochumsen and Casper Hveneegaard Rasmussen.
Apputveckling : En studie av motsättningar mellan design- och användningspraktiker ur ett verksamhetsteoretiskt perspektiv
We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

Motivation is a key factor for maintaining a healthy lifestyle and together with the help of today?s modern technology, facilitating new innovative approaches has made it easier to motivate people towards regular physical activity. This study aims to examine how a training application can increase motivation and how behavioral change occurs when using a training application. Qualitative data collection methods such as interviews and observations have been used in this study.
Lönearbetet, Arbetslösheten och Möllevången : En studie i arbetslöshetens vardag och dess platser
The study is divided into three parts ? the development of wage labour towards becoming the dominant norm in society, how this norm is challenged in a specific geographical context, and lastly a study of two unemployed individuals and their everyday activities, what and especially why certain behaviour occurs. The main purpose with the text is to study unemployed people in a specific geographical context in a overall society where wage labour is thought to be the norm. Questions that is being asked is how the unemployed individual works in a society where wage labour is the dominant activity for the day. This is connected to a study of Möllevången, a district of Malmö, where the wage labour norm can be thought of as being challenged.
Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)
Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to
impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in
deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate
deciduous forest.
