AbstractObjective: The aim of this study was to investigate the statistical properties of a self-assessment instrument for depression, Känsloläge, with regard to validity, reliability and factor structure. Method: The data collection method used for the study was mail questionnaires. The sample consisted of patients who had received treatment for heart failure, arrhythmic disorders or coronary heart disease at a hospital in Uppsala, Sweden. The study population consisted of 53 patients. The self assessment form?s validity was analyzed by measuring the criterion validity.
Analys av spänningsstabilitetsberäkningar i det svenska elsystemet
Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
Clash of Civilizations Myt eller verklighet?
In 1989 the Cold War ended and in 1991 the Soviet Union ceased to exist, over night the ruling paradigm of International Relations was obsolete. What would happen now? Samuel Huntingtons answer was that in the future, cultural identity would be the most important factor behind international conflict. And that the threat of world war would come from clashes between civilizations instead of clashes between ideologies like during the cold war. Was he correct? This thesis is an attempt to find out if Huntingtons theory was right in its predictions of the world to come.
Är egenföretagande en riskfaktor för alkoholmissbruk?: en studie om egenföretagande och dess villkor kan vara riskfaktorer för alkoholmissbruk
The aim of this essay was to obtain an understanding about company owners thinking about the connection between having an own company, and the risks for an alcoholic abuse. The risk factor I was researching was stress, alcoholic culture, accessibility and rehabilitation.I have interviewed five owners of small companies, two women and three men, which represents four different kinds of branches. The theories I used in analysing the empirical findings where the theories of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and culture perspective.I have found that the main stress factors for company owners where the economical stress and great load of work. The stress was also related to the fact that company owners of small companies often were alone with all the responsibility and problems.Women did not use alcohol very often as a tool to reduce stress. If individuals were using alcohol to reduce their stress, it also had to deal with their ability of coping and also what channels they had for coping..
Buntning av grot med lastbilsmonterad utrustning :
During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.
Motivationsfaktorer : - Vad påverkar motivationsnivån hos telefonförsäljare?
Through an examination on a Telemarketing company this paper aim to investigate which relations there is between the level of motivation and performance and how these are related to the factors that are included in Herzbergs two-factor-theory.In this essay we have been using a questionnaire and interview. We have also been able to collect statistics on employees from the Telemarketing company we examine. On the basis of these data we have analyzed which relations there is.The examination shows on relations who mean that the factors Performance and Acknowledgement are the ones that affect the motivation the most, and therefore the level of Performance. The rest of the Motivation factors don?t show any clear relations.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.
Eurokoder : en jämförelse mot BKR
In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.
Nyandlig personlighet
Denna studie syftar till att undersöka sambandet mellan personlighetsdimensionerna enligt Five Factor-modellen och attityder till andlighet och livsåskådningar enligt New Age. Även eventuella skillnader mellan könen och åldersgrupper i relation till New Age studeras. Studien utfördes som en kvantitativ undersökning i form av en enkät, bestående av en svensk översättning av Big Five Inventory (BFI) för att mäta personlighet och New Age Orientation Scale (NAOS) för att mäta attityder till andlighet och de livsåskådningar som karaktäriserar New Age. Resultatet visade ett signifikant positivt samband mellan personlighetsfaktorn Öppenhet och människor som tilltalas av andlighet och livsåskådningar enligt New Age. Inga relationer till de andra personlighetsfaktorerna inom Five Factor-modellen och New Age konstaterades.
Självscanningssystemet : Dess för- och nackdelar
The purpose with our thesis is to understand and explain the advantages and disadvantages there is with the self scanning system. The advantages and disadvantages we will highlight from three different angels; the store management perspective, the staff perspective and the customer perspective. These three perspectives will together form an overall perspective over the advantages and disadvantages as the self scanning system has contributed with. Finally we will highlight the differences and resemblances we have found between the perspectives.Through a qualitative approach we have gathered data to our thesis. Furthermore we have based our theory chapter and our empirical chapter on the base of Grounded Theory.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.
Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm
The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
Utmattning av vägbroar i armerad betong enligt eurokoder
Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.
?Du kan göra skillnad i människors liv utan att ha en aning om det? : En kvalitativ studie om några socialsekreterares syn på suicidalitet
During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.
