Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

The purpose of this study was to examine how the social services are applying the sections of the law concerning custody transfer within foster care. More specifically the aim was to find out what circumstances are underlying the social services decision to go through with a custody transfer within the foster care, and to find out which difficulties and possibilities the law offers when it comes to this process. The study was based on interviews with six respondents, within the social services, who have great experiences working with these issues. The study concluded that there are several factors which affects the decision whether to implement at custody transfer or not, and some of these are the child?s attachment, the child?s fundamental needs and consent from the involving parties in the case.

A large number of children and teenagers are placed in foster care for various reasons. Social services have a responsibility to follow up youths and ensure that they have the same opportunity for positive development as other young people. A qualitative study was conducted with an abductive perspective by gathering material from social workers in this particular field. The research design of this study is an interview study. The theoretical premise was Bronfenbrenners ecosystem theory and Maslows hierarchy of needs theory.

Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns..

Pappersmakulatur uppstår i tryckpressarna, men orsakerna finns i företagets alla funktioner. För ett framgångsrikt förbättringsarbete med att minska makulaturen krävs därför att all personal är engagerad.Examensarbetet utfördes på Bobergs Tryckeri AB i Falun, ett familjeägt företag med 60 anställda, som producerar personifierad direktreklam och blanketter. Syftet var att undersöka hur pappersmakulaturen kan minska och målet var att hitta orsaker samt ge förslag på åtgärder för att minska den.Genom intervjuer med personalen kartlades produktionssprocessen och utifrån det utarbetades förbättringsförslag. Exempel på förbättringsförslag är att kontinuerligt mäta och rapportera makulaturen, förbättra kommunikationen mellan avdelningarna och utveckla färgstyrningen. Litteraturstudier och kontakter med nyckelpersoner inom branschorganisationer och andra liknande företag, var till stor hjälp i arbetet.

Lean has been studied intensely since the 1980s and it has been tested and successfully implemented in a wide variety of businesses. This thesis aims to examine the potential effects of a Lean implementation on meeting efficiency, a topic that has gotten little attention in the research community. First, a number of meeting problems are introduced, as they are perceived from the company that is the subject of the study. Second, the potential of introducing Lean in a meeting process is evaluated using the Lean Thinking principles. Third, the wastes that are generated from the meeting problems are identified.

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

In this thesis I have done a discourse analysis of the documentary movie A Jihad for Love. A Jihad for Love came out 2007 and is directed by Parvez Sharma. The documentary movie is about homosexual Muslims and their jihad, struggle, for love and to be accepted in a world where they are barely recognized as a group. My aim of the thesis was to see how the movie portrays the persons who are in the film and their relationship to Islam and who gets access to the religion. I have also analyzed if Islam can be used to strengthen the sexual identity or if it works in the opposite way.

This study is based on the feminist belief in the importance of a reorganization of the existing gender hierarchy, where women have less power than men. Since news media reflect as well as contribute to create the reality we live in has the purpose with this study been to shed some light on how the gender structure is expressed in Sweden?s most popular television news program. I chose to examine one broadcast per day from the Public Service SVT news program Rapport during January 2010 using quantitative content analysis and the result was as follows:65 % of the news programs was presented by a woman news anchor 36 % of the news reports was carried through by a women journalist 31 % of the interviews contained a female participant The representation of female participants in interviews did not depend onif the journalist was a woman or a manThe representation of female participants in interviews did not depend on if the report was from Sweden or abroadWomen were more often than men interviewed in the role as nursing staff, development aid worker, teacher or principal, parent of a son, retired and sick or sick leaveOnly men were interviewed in the role as rescue worker, custom staff, member of the armed forces, house owner and tourist..

The purpose of this essay is to illustrate the ideas that have influenced parents' choice of a Christian private school and how parents justify their choices. The essay also aims to examine the expectations that parents have in the schools, as well as the pros and cons as they consider private school compared to other schools.My study is based on qualitative data collected through interviews with parents who have chosen to place one or more of their children in a specific Christian private school. Using a qualitative approach has made it possible for me to get a deeper understanding of this investigation. I have also used the previous research on this field and theoretical starting points to explain and connect to my inquiry as Maslow's hierarchy of needs and the school Weber document types and identity in a multicultural society.The study shows that parents seek to or from the public school due to various reasons. To seek out a Christian private school depends on different reasons.

I takt med att medvetenheten för miljön ökar så ökar även återvinningen på många håll i samhället. Förut har återvinning alltid skett närhelst det varit ekonomiskt lönsamt, nu finns det dock en allmän uppfattning i samhället att återvinningen är alldeles för låg för att vi skall kunna ha en ?hållbar utveckling?. Denna ökade miljömedvetenhet har lett till förändringar i vissa kommuner i Sverige där man infört att hushållen måste betala en avgift för varje kilo sopor de genererar. Denna uppsats ämnar försöka utvärdera detta ekonomiska styrmedel ur en effektivitetssynpunkt.

Aim: The aim of this qualitative interview study was to describe the nurse's professional role and the role as a patient during different time periods. Data were collected through semi-structured interviews, where respondents had a link to the nursing profession, either as a student, now working nurse or retired nurse. Method: The data were analyzed using a content analysis. Result: The older nurses believe that nurses today has a high status and is seen as a well-read and well informed person. Most respondents believe that collaboration between nurses and doctors has improved since past.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .
