Hur påverkar hörselskadan det dagliga livet? En jämförande studie mellan barndomsdöva och vuxendöva.

The study emanates from the national quality registry for persons with severe and profound hearing impairment. The aim was to examine possible differences between signing deaf and adults with acquired severe hearing loss, with reference to self-assessed problems, how the hearing loss influences daily life.In total 234 adults aged 30-90 years were included (128 women, 106 men). In the registry, there are background variables and questions that the patients have answered. The results, indicated on a visual analogue scale (VAS) from 0-100, from a question ?To which extent does your hearing loss at present influence your life?? were analysed.The study was performed by pooling the results of VAS and dividing the patients into signing deaf and those with acquired severe hearing loss, and in age groups 30-60 and 61-90 years.

En studie av evalueringar av webbaserade söktjänsters återvinningseffektivitet

The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Snedställningskrafters påverkan på prefabricerade pelar-balk stommar

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

EU och folkomröstningarna En undersökning om de europeiska ländernas skiftande karaktär och hur dess väljare agerat i förhållande till detta

33 referendum has taken place in european states regarding the European Union since the fall of the Berlin wall. This thesis aims to initialy identify potential patterns in this group of referenda to launch and test a theory/hypothesis anchored in this pattern.The european states are differing in nature and the standard of living is chosen as the factor that can potentially have affected the outcome of the referenda held. The carrying thought here being that the voters in states with considerably lower standard of living than the european average would have a more positive attitude towards a deepened cooperation among european states.To try this connection between standard of living and how european citizens have placed their votes a main and principal quantitative test is undertaken. It is followed by discussion and arguments about the result of the test.The argumentation goes from being hopefull of the strenght of the hypothesis, to a more ciritical view of its' strength. The thesis is wrapped up in some argumentation about how and why it fails to explain what it was initially intended to do.

"The Heart of Sweden" : -profilering av Örebroregionen

Den latinamerikanska befrielseteologin är en kristen teologi som har sitt ursprung i slutet av 1960 och vill befria de fattiga och förtryckta människor i latinamerika. Denna rörelse uppstod på grund av sociola orättvisor, fattigdom och mänskliga rättigheter i utvecklingsländer i Sydamerika och har kritiserats av den romersk-katolska kyrkan.Därför, från ett pedagogiskt perspektiv, är det en intressant fråga om denna teologi är representerad i läroböcker i religionsämnet. Syftet med denna studie är att analysera om den latinamerikanska befrielseteologin är presenterad i läroböckerna.Denna forskning bygger på fem läroböcker som har granskats genom en textanalys och en enkel kvantitativ analys för att besvara studiens frågor.Resultatet visar att latinamerikanska befrielseteologin presenteras i de analyserade läroböckerna, men mämns inte vid namn i de två senast skrivna.   .

Backsourcing : om dess orsaker, syften och alternativ

This paper examines the reasons behind firms considering backsourcing. While firms experience problems with their outsourcing activities, backsourcing emerges as an alternative solution. Firms primarily take cost considerations into account when reconsidering their outsourcing practices, but this only scratches the surface. A deeper analysis is needed, since cost increases arise from issues such as quality defects and cooperation problems. Even though production costs are low, outsourcing always implies transaction costs.

Fysisk träning som hjärtrehabilitering efter en myokardieinfarkt: en litteraturstudie

Background: Myocardial infarction is the most common individual disease among people in the west world. In Sweden there are over 50 000 women and men who get myocardial infarction every year and about 40 % of them dies. Exercise training is one part of cardiac rehabilitation and since 1980 Sweden use the guidelines from that time. Aim: The aim was to review exercise-training modalities in cardiac rehabilitation after myocardial infarction and the physiologic- and psychological effects. Method: Facts were obtained by searching through the database PubMed for articles published from 1994 and ten years forward.

Torasemid vid hjärtsviktsbehandling

Hjärtsvikt är ett tillstånd då hjärtfunktionen försämrats och cirkulationen inte förser kroppens alla organ med tillräckligt stort blodflöde. Vid hjärtsviktsbehandling är loopdiuretika viktigt för att behandla ödem då det verkar vätskedrivande. Torasemid är ett loopdiuretika som har visats vara effektivt och bra tolererat. I flera studier har effekterna jämförts mellan torasemid och furosemid varvid många betydelsefulla och förmånliga effekter har observerats för torasemid. Syftet med litteraturstudien var att ta reda på om torasemid kan vara ett bättre alternativ till furosemid vid hjärtsviktsbehandling, om torasemid bör kombineras med spironolakton, om furosemid borde sluta användas och varför torasemid inte används i större utsträckning vid hjärtsviktsbehandling. Slutsatsen av litteraturstudien är att torasemid borde användas istället för furosemid vid behandling av hjärtsvikt, vilket grundas på de fördelar som har redovisats i genomförda studier.

Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

Livet efter ett hjärtstopp

SAMMANFATTNINGI Sverige drabbas ca 10 000 personer av hjärtstopp utanför sjukhus varje år. Överlevnaden är låg, men på senare år har åtskilliga insatser gjorts för att förbättra dessa siffror. Bland annat har man börjat utbilda brandmän, säkerhetsvakter och taxichaufförer i hjärt-lungräddning med defibrillator och numer är hypotermibehandling en vedertagen metod för att skydda den ischemiskt skadade hjärnan. Trots detta kan dessa patienter drabbas av funktionsnedsättning på grund av den syrebrist i hjärnan som ändå uppstår till följd av hjärtstoppet. Det är viktigt att ha kunskap om hur dessa patienter mår och klarar av sin vardag sedan de lämnat sjukhuset, för att kunna ge det stöd de behöver för att kunna återgå till ett så normalt liv som möjligt.Syftet var att beskriva livssituationen hos patienter som drabbats av hjärtstopp med fokus på livskvalitet, kognitiva funktioner och ADL.Forskningsöversikt valdes som metod för att få en samlad bild över aktuellt kunskapsläge inom detta problemområde.

Sensorfusion för undervattensrobot i kärnteknisk miljö med Kalman filtrering

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

Den psykosociala arbetsmiljöns betydelse och påverkan på ohälsan

This paper is about the psychosocial work environment, and those factors that can be responsible for an employee?s sick leave. We have through our knowledge from working life, on several occasions experienced colleagues becoming ill, the cause being the psychosocial working environment. Private factors, for instance different kinds of life crisis like a divorce or uprooting, have contributed to the sick leave. The psychosocial working environment is complex.

Förvärv och försäljning av fastighet med förorenad mark : Särskilt gällande ansvar och friskrivningsklausuler

Properties are bought and sold daily, which means that it is of great importance with rules that regulate the acquisition. The rules on who should be held liable for a property brought to a head when the acquisition relates to a property that is loaded with contaminated soil. The purpose with this thesis is to investigate who could be held liable for contaminated land and also whether an exclusion clause can affect the separation of responsibilities. Two different liabilities can occur depending on which law that should be applicable, MB or JB.MB's rules apply to anyone who may be subject to decontamination responsibilities, which is regulated in Chapter 10.
