When different type of programs are developed one wants to make these adjustable to future changes and requirements. It must be done a good design of the program from the beginning to make it possible to continue development of it without having to redo big parts of it to high costs. In the area of object orientation there are design pattern, which can be used to design systems that can be adjusted to new changes in an easier way. I have in this thesis chosen to take a closer look at how to design a program that sends SMS to cell phones through a system of an operator. One requirement on the program is that it has to be possible to change what operator to send though in an easy way.

Background: More focus has been placed towards autonomy when it comes to care and in special towards palliative care. The purpose with palliative care is to relieve and support at the end of the life. When the patient has difficulties to communicate to those around him due to his illness it is hard to preserve the patients right of self-determination. It is very important to consider the patient as autonomous during the course of the illness. Different alternatives have been developed to preserve the patient?s autonomy such as dedicate a deputy or plan the care of the patient in advance.

In 2006 there was a change in LMA (1994:37) that clarified the division of responsibility be-tween the Migration Board and the municipalities, concerning unaccompanied children. The social services should now be utmost responsible for the housing and care of these children, to assure that they gain the same standards and rights as all other children. The aim of this essay has been to examine how the division of responsibility has influenced the work of the social services and how they interpret their responsibility for the unaccompanied children. How do the social services investigate and make decisions concerning these children? Do these chil-dren have the same rights as other children? To answer these questions a legal study was made, followed by qualitative research interviews with four social services that receive unac-companied children.

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

There are several objects of age whose provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.

The purpose of this essay is to raise and discuss children?s problems with concentration in two areas, stress and Adhd, where the symptoms are similar to each other. During recent years I have experienced how "difficult" children increasingly have been diagnosed and "stamped" with various combinations of letters. Because of my own children?s diagnoses, this has raised my interest in studying children´s modes of expression and behavior, and I have come to question whether many children who receive a diagnosis of Adhd really are afflicted by it.

The main purpose of this study is to examine and gain increased knowledge concerning the legal security of children taken into protective care. The purpose is also to enable contemporary social workers to reflect around phenomena in today´s social work, among other things how investigations are carried out surrounding children taken into protective care thought this historical study. To find out how social workers dealt with caretakings I have chosen to examine the personel files that the social workers compiled for each child and also interview a man who worked as a social worker at the time of the investigation. The paper is divided into two part studies were the first one studies legal security through Mattsson´s (2002) further development of KjÆnstad?s way to analyse legal security, namely through investigating the clarity of the law, procedural rules and the comtetenay of the social workers.

In scientific investigations on how organizations can learn from their mistakes the perspective is usually that of the social engineer; the object is to prevent human errors through modeling the system in a certain way. The aim of this paper is to explore the learning process from a different standpoint than those usually applied in organizational learning and error theory. By studying the learning process in Swedish health care I seek to discover how theoretical presumptions affect the outcome in terms of what we actually learn. The theoretical framework draws on two major discussions in contemporary political science; the question of structure and agency and the question of whether to focus on formal or informal structures when explaining organizational behavior.The investigation shows that Swedish health care tend to understand human errors as a result of formal organizational structure. Such a view leads to insufficient explanations to why errors occur but is useful in producing preventative measures.

It takes a very long time for ionizing radiation of used nuclear fuel toreturn to a natural background level, for this reason one of the requirements for theselection of the location of a repository was that the environment as well people'shealth would be protected from the harmful effect of radioactivity. This requirementmeans that the waste must be isolated in a geological formation. In Sweden therepository will be built in the crystalline bedrock. The location for the Swedish nuclearfuel repository at nearly 500 meters depth at Forsmark in Östhammar was decided 3June 2009. The repository will be located at Söderviken, close to the Forsmarknuclear power plant in a 1.90 billion year old bedrock that will accommodate 12,000tons of spent nuclear fuel.

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Researchers in the field of political corruption generally expect voters in democratic states to lose trust in corrupted politicians. However, there are cases where corrupted politicians maintain their popularity, a phenomenon studied in this thesis. Focus lies on three cases of political corruption: the Italian Prime Minister Silvio Berlusconi who has been the subject of several judicial investigations and court cases; the impeached former president of Lithuania, Rolandas Paksas; and the German Christian Democratic Union's (CDU) involvement in a party funding scandal. The cases are chosen based on the method of agreement. Berlusconi, Paksas and CDU have all, in spite of their corrupt behaviour, kept or regained popular support among a large group of their country's citizens.

Heat and power stations are often in need of optimizations. A simulation model is a tool for findingways to optimize the plant. The scope of this diploma work is to develop a simulation model ofBoiler 5 at Mälarenergi AB. Boiler 5 is a circulated fluidized bed boiler that was taken into service inyear 2001. Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

In 1985 the Swedish Association of Local Authorities and Regions published a paper on recommended depreciation time on capital assets for the public sector. This paper should only be seen as guidance, but many municipals use it without any further investigations. Swedish municipals are not like private companies; one very distinguished difference is that they are not allowed to make any profit. The municipals in Sweden are regulated by the constitution law which means that they can not go bankrupt. The public and the private sector have different legislations that result in different ways on how they for example treat depreciations.

This masters thesis shows that the changes in the scientific publishing system have affected the academic libraries. Both technological change and the increased prices on scientific journals have forced academic libraries to take action. Some Swedish academic libraries have started publishing the university s own research material. The issue has in many cases been treated more as a library concern, than as a concern for the university as a whole. Neither has there been a national coordination of these matters in Sweden.
