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.

This study?s purpose was to examine which main forms of teaching methods that occurs in the Swedish nine-year compulsory school and how often learning through social collaboration take place. The study contained literature and interviews with eight teachers.

The aim of this study was to examine the existing discourse of youth robberies from year 2003 to year 2013 in DN and Aftonbladet. By using discourseanalysis as theory and method I have studied newsartikles from these two newspapers.The study shows that the portrayal of youth robberies is focused on the young muggers as a group and not as individuals. The groups that are mentioned are young men and women, children and muggers with another ethnical background than swedish. Girls, children and ethnical background are given more attention in the articles, and are portrayed as more problematic. The youth robberies are described as brutal and are focused on the young muggers as unrestrained, evil individuals with no future.The analysis also shows that a change in the discourse is taking place during the studied period.

Inspection errors are nowadays usually written with pen and paper during building inspections. A company in Stockholm is developing a method by which inspections are made digitally from the beginning and where the inspection attachments shall be stored in a database. The idea of this method is that entrepreneurs can use the database to get an experience feedback from previous surveys so that they can improve their production processes. One problem that occurs is how inspection errors will be sorted into the database. They have to be sorted so that contractors or clients can use and sort out the information in a sensible way when they want to evaluate and make improvements in their production processes.This thesis examines how the inspection errors can be sorted in a structured manner.

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

In the beginning of the 21st century, a number of scandals were pointed out in the US. Enterprises like WorldCom and Enron went into bankruptcy, and inaccuracies in their account were made public. This led to the fact that a new law, SOX 404, was established in the US. The law says in its whole that enterprises must have better control of their internal accounts.The aim with this paper is to examine how the surrounding world of an organization with stakeholders as well as other surrounding elements, affect or force an organization to change, and how a changing process is introduced and accomplished.We carried through a survey as well as interviews at the actual organization. Furthermore, we investigated why the change has come into practice as well as attitudes and opinions towards the change, and lastly, how the changing process has been accomplished.

AbstractThe purpose of this study is to illustrate Serbia?s democratic development on the basis of consolidate democratic perspective. Linz & Stepan´s five arenas (political, civil, economic, legal and bureaucratic) are required for the possibility to become a consolidate democracy. In order to fulfil the aim, I have chosen to focus on the political and civil arenas that are most central in the study of consolidate democracy.The purpose of this study is to process how far Serbia has come towards a consolidate democracy and which obstacles still remain in the transition.The questions in this study are:? What problems has Serbia faced since the democratic transition in the beginning of 1990?? What possibilities are there for Serbia to consolidate the democracy, with focus on the two key arenas of consolidation?By applying the theoretical framework to the data, I have been able to present answers and build up an analysis.

Syftet med det här arbetet var att ta reda på vad jag som lärare kan lyfta fram i exempeltexten The Old Man and the Sea för att främja elevers förmåga att tolka innehållet i en text. Detta har jag framfört i en analys av romanen med hjälp av Peter J. Rabinowitz teori om konventionella regler i hans bok Before Reading (1997) genom att tydliggöra hur romanen kan förstås med hjälp av de konventioner som Hemingway såväl som hans läsare har att förhålla sig till. Vad jag visat är hur dessa konventioner som jag framlagt i analysen, till exempel avvikande detaljer i texten, förhåller sig till ett mera litterärt kompetent sätt att tolka genom att koppla dem till Örjan Torells (2002) teoretiska modell för litterär kompetens..

The construction industry has demands on energy use in permanent buildings. How much energy that is permitted to use during the time the building is produced has no requirements. The purpose with this study is to learn how far Skanska has come with the work of making the building site more energy efficient.A literature study has been performed in the beginning of the study to survey what energy efficient arrangements that can be applied and how they operate. Using site visits and interviews the situations on the building sites have been studied as well as the energy efficient measure that are in use.Skanska has come a long way with the work of energy efficient building sites and they keep improving. They have improved half of their cabins so they use 50 % less energy.

This essay focuses on four different aspects of readability: voice, causality, advanced words and the LIX-value of words. Each of these four facilitates or aggravates reading comprehension for students, which is further defined in the paper. The study is an analysis of textbooks in history for 8th grade from a second language perspective. In terms of voice, causality, advanced words and the LIX-value of words, the study shows that books with higher grades of causality and voice and lower grades of advanced words as well as a low degree of LIX-value are better for students to work with..

Inom disciplinen kognitiv ho?rselvetenskap tilla?mpas en integrerad ansats da?r taluppfattning beskrivs ur ba?de ett auditivt bottom-up-perspektiv och ett kognitivt top-down-perspektiv.

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

This study deals with the compulsory reading of the public announcements in churches during the eighteens century. The focus is on the diocese of Skara. The ambition to make a comparison between the parish of Skara and the parish of Gårdstånga, earlier investigated by Elisabeth Reuterswärd, failed due to few archives from the parish of Skara. My study takes a broader perspective of the signification of the announcements to the reverends and to the churchgoers. It was an obligation to the reverend to read, collect and save the announcements and the churchgoers were by law obligated to go to church every Sunday.
