The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

Background: Schizophrenia is a serious disease with potential to implicate consequences on both the family and the sick. Nurses have a fundamental responsibility to relieve suffering, and also to offer support to both the individual and the family.Aim: To illuminate experiences of being a family member to a person with schizophrenia.Method: A systematic literature review was chosen. Nine articles were included. After having analyzed the results six categories were found.Result: The family members experienced the disease as fluctuating and stressful. Some felt ashamed for their sick family member and withdrew from the rest of the society.

Bakgrund: Sjuksköterskor skattar sig att bli stressade av tidsbrist och resursbrist. Moralisk stress uppstår ur dilemman. Dilemmat uppstår när det finns begränsningar i organisationen, konflikter med bedömningar som andra har gjort hindrar en att göra det som egentligen anses riktigt och tankar uppkommer om vad som ska göras istället. Syfte: Att undersöka distriktssköterskans erfarenhet av stress i sitt arbete på vårdcentral med fokus på moralisk stress. Metod: En kvalitativ studie med semistrukturerade intervjuer har genomförts med åtta distriktssköterskor och analyserades med manifest kvalitativ innehållsanalys. Resultat: Distriktssköterskorna erfor stress i många olika situationer och det som var mest framträdande var tidsbrist samt situationer i telefonrådgivningen. Det fanns ett större vårdbehov än vad det fanns läkartider och då kunde inte distriktssköterskorna ge den vård som de önskade. Regler och rutiner kunde upplevas som hindrande i mötet med patienten vilket gav uttryck som frustation och tankar om vad som var rätt att göra. Slutsats: Distriktssköterskorna upplever stress, oro och frustration vid stor vårdtyngd, lite personal, brist på läkartider och när kommunikationen mellan kollegor och patienter brister.

Background Swedish nurses are required by law to document nursing care. Studies have proved scarce in nursing documentation with regard to written language, the nursing process and the nurse´s caring perspective. Educating nurses in using the VIPS model have improved nursing documentation. Few studies have included nursing documentation of psychiatric care.Aim The aim of this study was to describe nursing documentation within psychiatric care of inpatient settings.Method A quantitative, retrospective descriptive research design was applied. A total of 60 nursing journals from a psychiatric department of six wards were studied.

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.

Every year an avorage of 40 000 Swedes fall ill with different forms of cancer. Chemotheraphy has an effect on the tumour cells as well as the healthy cells in the body, this causes many side effects which can be very problematic for the patient. The study was carried out in order to indicate the care measures that are taken to deal with the side effects i. e stomatit, loss of hair and sickness/vomiting, that are connected with chemotheraphy so that the outpatients will experience a quality of life. The method used was a qualitative interview with six nurses from the South if Sweden, all of whom are working with chemotheraphy patients.

Background.Telephone advice increases the accessibility to health care and the streamlined work at primary health care centres. The goal of telephone advice nursing is to give the caller a correct advice, adapted to the caller?s situation, in order to reach correct care level. However, registered nurse?s telephone advice includes risks for misjudgement.

The purpose of this master?s thesis is to study resource allocation among district libraries within Stockholm?s City Library (SSB) on three different occasions ? 1996, 2001 and 2005 ? and to examine whether there exist any inconsistency between the state of the allocation of resources and what might be considered reasonable. During the course of the study, it became apparent that some measurements are more relevant than others when determining whether the allocation of resources is reasonably fair. The most relevant ratio is the share of net cost per capita in relation to population and the population?s composition of children, youngsters and persons with foreign background as a result of relevant political governing documents giving priority to these three groups.

Vattenfall district Heating power plant in Uppsala produces district cooling with absorption heat pumps which leads to a large amount of waste heat that has to be cooled with evaporative cooling towers. The Environmental Court has ordered Vattenfall to survey the possibilities to recover the heat, which is the focus of this thesis.The study begins with an overview of the system, and conditions and limitations for waste heat recovery is examined. In the next step alternatives to recycle the heat is evaluated, either by direct recovering or by upgrading.First, the technical possibility of each alternative is discussed, and then the operation time and the amount of recovered heat is calculated. Those alternatives which are possible are brought further to an economic analysis.The cost of investment for each alternative constitutes the basis for a present value analysis. The results are put together in a table where the total amount of recovered heat is compared with the present value for the different alternatives.

The aim of this study was to investigate leadership in public health care. The methods used were shadowing and semi-structured interviews. The shadowing involved observing the shared leadership of two head nurses in an administrative management position of a ward in their daily work during two weeks. The observation was supplemented by ten semi-structured interviews. A thematic analysis of the data was carried out and the result indicated that shared leadership is a form of leadership well suited for an organisation as big and complex as the clinic where the study took place.

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.

The aim with this master thesis is to study which ambitions and strategic aims Gothenburg?s district libraries have regarding their music sections. I have utilized my theory from Sanna Talja, a Finnish researcher in Library and Information Science. She identifies three perspectives in maintaining a music library. She calls them, general education, alternative and demand.
