The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

Inom undervisning av Objekt-Orienterad Programmering (OOP) blir metaforer ett allt viktigare redskap. En av anledningarna till detta är bland annat metaforers kapacitet till att underlätta undervisning av ämnesrelaterade koncept. Den här rapporten syftar till att synliggöra och analysera lärares bruk av metaforer som redskap och stöd i undervisning av OOP. För att möjliggöra det här har jag genomfört ett antal intervjuer på ett gymnasium i Skåne. Intervjuerna har skett med lärare som undervisar i OOP-relaterade ämnen.

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

Syftet är att utveckla och dokumentera en metod för användarnära utveckling av terränganalysmoduler inom ramen för försvarsmaktens GeoPres-koncept. Dessutom skall det utifrån denna metod utvecklas ett siktfältsanalystillägg med brett användningsområde. Siktfältsanalystillägget skall förenkla arbetet med siktfältsanalyser och skall kunna användas i Norra Militärområdesstabens nätverk. En metod för utveckling av terränganalysmoduler inom ramen för försvarsmaktens GeoPres-koncept togs fram med tio olika steg. Den utvecklade systemutvecklingsmetoden användes sedan för att utveckla ett siktfältsanalystillägg till ArcView.

The main purpose of this essay was to study whether niche parties that were represented in municipal councils in Sweden during the 2007-2010 term of office were politically relevant. Furthermore, factors that might facilitate political relevance for niche parties were studied. Political relevance was studied using two theoretical perspectives. The objective model of political relevance presents four categories of relevance based on the relations between political parties in a political assembly; governing parties, coalition parties, blackmail parties and isolated parties. The subjective model of political relevance relies on the party representatives? own judgments of the relevance of their parties.

Today`s society requires that municipalities focus must be more on effectivity and quality. Because of this it is important for municipalities to look after the controlling systems. Many municipalities choose to adopt models that reflect the efficacy. The municipality of Vellinge has chosen to implement balanced scorecard in all their efficacies. We found it interesting when it was exposed that 70 % of all implementations of balanced scorecard fails.

The aim of this Masters thesis is to, through user studies, analyse whether Carol C. Kuhlthaus information search model is applicable in a Swedish school. Furthermore, the guidance that the students may receive from the teacher and/or school librarian is analysed. Answers are sought to the following questions: · How do the students perceive their information seeking? · How do the librarian and/or teacher support the students during their information seeking process? The study is based on a qualitative method of approach, through interviews with four informants: a librarian, a teacher and two pupils.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

Målet med examensarbetet var att skapa ett verktyg för insamling av erfarenhetsdata för produktutvecklingsprocessen. Den skall vara användbar för att bidra till ett systematiskt arbetssätt för produktionsanpassad konstruktion på Volvo Aero Corporation. Det skapade verktyget för insamlande av erfarenhetsdata skall bidra till att produktivitet och producerbarhet kan förbättras på kommande koncept och konstruktioner. En förstudie har genomförts på företaget under hösten 2010 vilket ligger till grund för det beskrivna problemet i examensarbetet.Arbetet avgränsades till att utveckla en struktur för hur metod och erfarenhet skall struktureras och en testversion av verktyget togs fram för utvärdering. Efter samråd med den handledande Verksamhetsutvecklingsgruppen, VU-gruppen, från avdelning 9931 Projekt-, Koncept- och Tillverkningsledning, beslutades att examensarbetet skulle avgränsas ytterligare till insamling av diametermått på komponenten Diffuser Case på Volvo Aero.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

The use of subscription services directed towards customers has become a common phenomenon in a vast number of different industries. We have noticed a clear trend of new businesses emerging solely offering subscriptions, and existing companies altering sales of their products to become parts of subscriptions. But research has not caught up with this trend yet, especially regarding why it occurs and how it affects existing businesses internally. The purpose of this study is to examine the driving forces for change and examine how existing businesses have to change parts of their business models to offer subscription services. The premise of this study has been Vargo & Luschs (2004) Service Dominant Logic with their foundational premises and Business Model Canvas by Osterwalder et.
