Sambanden mellan inandningsbara, grova och fina partiklar i luften och strokeanfall i Malmö

In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.

Alternativa dagvattenlösningar för nyexploateringsområden med avseende på substansflöden

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Från A till Ö : Vilka grepp kan tillämpas för att minska intrycket av en linjär miljö? Reflektioner kring arbetsprocessen bakom Electron.

Rapporten är en reflekterande text som behandlar arbetsprocessen och omkringliggande mål för ett examensarbete inom medier som bedrivits mot Högskolan Skövde. Syftet med examensarbetet har varit att finna grepp som maskerar spels linjaritet, det vill säga vilka knep som används i dataspelsindustrin (medvetet eller omedvetet) för att få ett spel med linjär level-design till att framstå som mindre linjär.Min analysmetod är hämtad från Espen Aarseths, Forskning på spel: Metodologiska ansatser till spelanalys (2007), där en av de totalt tre analysmetoder är vald; nämligen att själv spela igenom analysobjektet. De två återstående analysmetoderna presenteras kort under metodavsnittet. Därefter jämförs greppens betydelse i en rad spel för att därefter slutligen tillämpas i en egenskapad modul. Jämförelser görs med The Legend of Zelda ? a Link to the Past (Nintendo, 1991), Grand Theft Auto ? Vice City (Rockstar North, 2002) och World of Warcraft (Blizzard, 2001).

Bilden av Spelvärlden : Gravitationen som hjälp för mentala kartor

Alla spelutvecklare har någonting att vinna på att kunna ge spelaren tydligare minnen av spelvärldar. I denna uppsats undersöks hur plattformsmoment kan användas för att förstärka mentala kartor. Respondenter har letat sig igenom en labyrint baserad på spelet Brain Fudge med olika grader av gravitation, och resultatet tyder på att besvärligare plattformsutmaningar gör det svårare för spelare att få en bild av spelvärlden som helhet..

Modeflugor inom transportsektorn

During the time I've attended the programme to become a Transportation manager, I've been presented with quite a large number of different words. My purpose with this paper is to take a closer look at them, and see if they're sustainable concepts. This paper will be a literary study, and be on a wholly theoretical level. After a thorough examination of the various words, I've come to the conclusion that these words that I've chosen aren't just fad-words. They're going to be around for quite a while, this due to the fact that they're based on good ideas from the get-go.

Med idrotten in i kunskapssamhället

Abstract.In Sweden today, a collaboration was formed between the Swedish Sport Confederation andthe Swedish upper secondary school education. While this process was taking place, theSwedish Sport Confederation also tried to collaborate with the Swedish Academy. However,at the time the Academy did not have any involvement with the former.The purpose of the study was to research when and how the Swedish Sport Confederationcreated a collaboration with the Swedish Education Systems both on a National and Locallevel. I have also done a research on both the Knowledge Society and Elite sport talents tofind out if Elite sport will be affected in any way because of the existence of Knowledge Society,and also the reactions of the sports talents if any. My final pursuit was also to find out ifthe Knowledge Society can bring about a quick change to this silent conflict between theSwedish Sport Confederation and the Swedish Academy.For my study, I have used two different theories.

Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation graphs are compared between traditional cow traffic and Feed First? cow traffic.

Den byggda utemiljöns betydelse för människors motionsvanor : -Sett ur ett hälsopedagogisk perspektiv

AbstractIn order to investigate whether people living in Linköping city feel that the built environment affects their exercise habits, a quantitative cross-sectional study with qualitative elements was conducted. A questionnaire was the chosen approach in which information about exercise habits, education level, built environment was requested. The selected group was people working at Skatteverket in Linköping where many people work and where age, gender and education level varies. The built environment does affect the exercise habits, where major proportions choose to exercise in areas considered inviting. The majority of the respondents had a tertiary education, and many lived in the city of Linköping.

AimOur aim with this study was to examine how outdoor education is designed and experienced in three upper (senior) levels of compulsory school in Stockholm, and to compare it with the Norwegian equivalence.MethodOur method has been interviews with ten teachers, of whom six are Swedish teachers and four are Norwegian teachers. Two Swedish teachers are teaching in other subjects than Physical Education, four are teachers in Physical Education, two are teachers in Norway in Physical Education at and two are teachers in Norway at university level. Questionnaires were used to examine the Swedish pupils? attitudes towards outdoor education. 90 questionnaires were delivered, and 70 answered them.

Diskretionärt handlingsutrymme : en kvalitativ studie av socialsekreterares bedömningsgrunder vid ansökan om ekonomiskt bistånd

With this study, our purpose has been to achieve profounded knowledge and understanding regarding the use of discretion among social workers specialized in social allowance issues. The Social Services Act, structured as a framework law in the Swedish context, provides the social worker with a certain degree of discretion, in order to enable accommodated decisions depending on client case specifics. This study problematizes these aspects of legal security, and our intention has been to examine which factors impact the assessments social workers carry out in statutory decisions of social allowance applications. To attain this, we narrowed down our intention into a number of distinct and delimitated research questions: (1) Which elements of the client case impact the social worker?s assessment? (2) Which external aspects influence the social worker?s assessments and decisions? (3) How do social workers decide the client?s credibility? In order to establish answers to our research questions, we have utilized a qualitative approach of research by exerting qualitative interviews in addition to a vignette study.

Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

Estimation of heterosis and performance of crossbred Swedish dairy cows

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.

Neurointensivvårdspatientens förutsättningar för ett optimalt neurologiskt wake-up test : en observationsstudie

Background: Examinations with the intent to assess neurological functions and level of conciousness are common in neurocritical care, but the effect on the patient is not entirely researched.Aim: The purpose of this study was to describe the patient?s situation at the neurological wake-up test concerning the environment, nursing interventions and the possibility given the patient to become awake, and if these conditions affect the outcome of the wake-up test.Methods: A quantitative observational study took place at a neurocritical care unit, where 20 patients were observed from interruption of sedation to the neurological assessment, which was performed by a neurosurgeon or a specialized critical care registered nurse. Nursing interventions, environmental factors and physiological parameters were documented.Result: Twelve intervention varieties to control patients? physiological parameters were used. CPP > 80 mmHg was found in 90 % of observations.

Lindex - vägen till en tydligare logotyp

Lindex has a strong fashion position and is one of northern Europe's leading fashion retailers. Unfortunately their logotype no longer measures up to the fashion level that is required. Surveys and interviews have been conducted with employees at Lindex, disscusing their logotype. I have come to the conclusion that what is needed from Lindex side is strict guidlines for the employees to follow so that all information from Lindex to their customers is made with a great touch of fashion to it and in a coherent way..

Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
