Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.

The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

Oxytocin is a hormone which plays a crucial role in many reproductive and behavioural functions. It affects many organs and the classical peripheral targets are the mammary glands during lactation and uterus during labour. Oxytocin receptors have recently been described in a variety of normal tissues and primary cell cultures, but also in neoplastic tissues and established neoplastic cell lines, as breast cancer cell lines. The signalling pathways and biological effects of the oxytocin/oxytocin receptor system seem to depend on species, type of tissue, physiological versus neoplastic state and receptor location within the cell membrane.The aim of this project was to find out if the cell proliferation in the canine mammary carcinoma cell line CMT-U27 was affected upon stimulation of oxytocin, and to investigate the presence of oxytocin receptors in these cells. The cell proliferation was examined by using an ELISA-kit, where the absorbance measured is relative to the amount of living cells.

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

AbstractThe aim of this study was to illuminate and collect existing research from the beginning of the 21 st century about nurses work environment in institutional and elderly care in Sweden.A literature review was made by analyzing eleven scientific articles. The result showed mainly information about nurses work load. The information dealt with high work demands, too much responsibility, shortage of staff, time press and stress. Furthermore nurses reported a lack of co-operation between staff and management. An important part in nurses? work was appreciation from colleagues, management, patients and relatives.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

We must all take our responsibility to our common environment, we have to make sure that the following generation is guaranteed a healthy and good environment. Swedens universities have a significant role too achieve this. Environment questions have to integrate in the educa¬tion as a compulsory element, then more people will have an increased comprehension for the influence we have ion the environment. . My degree project have I decided to do about the environmental work at Halmstad University.

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

In this report we make an attempt to analyze where Swedish Twitter users believe the line is drawn between the private and public. Our goal is to find out what the factors are that determine what they decide to write on Twitter and what not. A survey was sent out and spread amongst Swedish Twitter users during one week to provide us with the data to answer our question formulation. The results do not draw an exact line between the private and the public but it nevertheless provides us with an idea of what users think is inappropriate to write about on Twitter. Through the study we found out that our respondents believe that it is inappropriate to write private information about others than them self.

The outdoor environment is the first thing you notices when you come to a pre-school and it also plays an important part in the development of children, their play and meeting their large motor needs. It is important that the outdoor playground is stimulating and inviting.My goal is to examine if the outdoor environment plays any role in the development of children and their interest in nature. What kind of thoughts do teachers and parents have about outdoor play, and is there a developmental goal for the children as well as what role do the teachers play in reaching these goals. In my work I want to show how an outdoor environment should be formed to help educationally as well as be safe and not least of all fun to be in..

Abstract:Ambulance nurses have in their everyday work a varied work environment, the pace of work can quickly shift from being calm and structured to be a severe acute situation.Objective: The aim of the study was to describe how professional nurses in the ambulance operations experience their physical and mental work environment in daily practice.Method: A qualitative interview study with semi structured questions was used. The study group consisted of two women and three men, ages between 27?42 years. The study was carried out on an ambulance station in central Sweden. Based on collected data, a qualitativecontent analysis was performed that resulted in three categories.Results: The result showed that the ambulance nurses regarded that it was a lot of heavy lifting.

This paper discuss the possibilities to improve the Swedish political nomination system. It brings up some of the values and norms that can be used to change the existing system. Values as openness, the demand of responsibility and also if there is values from the American spoils system that can be used in the Swedish system. A minor purpose is to discuss the part of the parliament within the nomination process. To investigate this I have some theoretical starting points and a self constructed analysis tool.

Difficult calvings and stillbirths are problems in Swedish dairy production that result in large expenses for the farmers and welfare issues concerning the animals. A common opinion is that the live weight of SRB and SLB is increasing, and whether increased weights have caused the increase in calving problems has been discussed. The aim of this study was to investigate the relationship between the relative birth weight (calf/cow) and calving difficulty and stillbirth, respectively. The importance of breed and parity for the relative weight has been investigated, and comparisons with previous studies have been made to evaluate whether the relative weight has changed over the last decades or not. The study was based on 807 calvings, registered during the period 1993-2003 in the experimental dairy herd of the Swedish University of Agricultural Sciences (Jälla).

This study is about how eurhythmic teachers create a comfortable and educational environment in their classrooms. In other words how they create a healthy working environment. Four teachers were chosen for the study, one of them male. I?ve used qualitative interviews because I believe it's the best method to collect information that illustrates what a teacher's working situation looks like and what he/she does to realize their own ideas.
