Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

Många äldre personer med kronisk sjukdom vårdas i det egna hemmet och behöver ofta insatser från öppenvården. Syftet var att belysa upplevelser av kommunikation för den äldre personen med kronisk sjukdom i mötet med öppenvården. Studien genomfördes som en litteraturstudie med 10 vetenskapliga artiklar. Betydelsen av att få tid och av att vårdpersonal lyssnar aktivt framstod som viktigt. Vidare vill de äldre personerna med kronisk sjukdom känna medkänsla genom att få uppmärksamhet och vänligt bemötande.

Background: Multiple Sclerosis (MS) is a chronic disease that mainly strikes young people in working age, twice as many women than men falls ill. Approximately 85 % suffers from MS-related fatigue that divides itself from common fatigue in that way that it is persistent and does not disappear in spite of sleep. This fatigue is experienced of many as one of the most difficult symptoms, which has considerable impact on the everyday life. Aim: The aim with the study was to elucidate how MS-related fatigue was experienced by persons with MS. Method: The study has been implemented as a literature study through systematic review of scientific articles.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Syftet med examensarbetet är att göra en trådlös version av det elektriska lås som tillverkas av Electec System AB.För att göra ett trådlöst elektriskt lås måste ett batteri monteras i låset. Batteriet måste hållas uppladdat hela tiden för att kunna driva motorn och ge strömförsörjning till elektroniken i låset. Alla signaler mellan låset och styrenheten ska dessutom överföras trådlöst istället för med kabel. Signalerna måste kodas innan sändning så att ingen obehörig kan läsa signalen och sedan öppna dörren.Det svåraste i ett trådlöst elektriskt lås är att överföra effekt från dörrkarmen till låset eftersom utrymmet är begränsat och avståndet mellan låsblecket i karmen och låset i dörren kan uppgå till 10 mm. För att överföra effekt från dörrkarmen till låset konstruerades en transformator.

The aim of this study is to examine social workers' and social work students' attitudes towards people living with hiv in Sweden. I will also examine if there is a connection between knowledge and attitudes. The questions at issue are how social workers' and social work students' attitudes can assume to influence on their professional practice and what causes can affect their attitudes towards people living with hiv. The study is based on a qualitative method. The methods have been: conversational interviews with five social workers, who work with family issues and integration, and a focused group interview with four social work students.

Schur AB är ett företag i Eksjö som erbjuder sina kunder lösningar inom post- och tidningshantering. Bland dessa lösningar ingår ett transportsystem kallat Gripper TGG 3200 vilket transporterar tidningar från exempelvis pressen till olika enheter i packsalen. Transportsystemet drivs av ett antal asynkronmotorer, antalet motorer variera med avseende på hur lång transportsträckan är. Då drivstationer och motorer är de dyraste komponenterna i transportsystemet vill man minimera antalet av dessaSystemet är uppbyggt av aluminiumprofiler som gör att det kan skräddarsys efter kundens behov. I profilerna rullar enheterna som transporterar tidningen i en sammanlänkad kedja.

Det här examensarbetet går ut på att utreda vilken påverkan oljeval och inkörningsmetod har på tätning mellan kolvring och cylindervägg i en fyrtaktsmotor. Arbetet har utförts på en motorcykel av märket Honda och modellen heter CBR 954 RR årsmodell 2003. Det diskuteras dagligen i tidningar, på internet och i garage runt om i världen om vilken typ av inkörning som är effektivast för att få en motor att gå bra och hålla länge. Vissa bil- och mctillverkare har helt tagit bort sina inkörningsrekommendationer medan andra fortfarande har kvar rekommendationen att man ska köra lugnt och på låga varvtal under ett visst antal mil. Eftersom att inkörningen påverkar väldigt många parametrar så finns inte möjlighet att testa hur olika oljeval och inkörningsmetoder påverkar alla dessa parametrar.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Inflammatory airway disease (IAD) is a respiratory disorder that most commonly affects young horses performing at a high level. The clinical signs are often mild but the disorder can cause a marked decrease in performance to a point where the horse has to be taken of training and competing. The aetiology underlying IAD is not yet fully understood. One current theory is that a type I-hypersensitivity reaction due to allergens in the environment is the cause in some horses. The most reliable diagnostic method is a bronchoalveolar lavage (BAL) since it reflects the inflammatory status in the most distal parts of the lungs, which are affected in IAD.
