The purpose of this study was to compare normal electroretinographies (ERGs) from three different canine breeds in order to evaluate if there were any marked similarities or differences between these breeds as to ERG responses. It is known that healthy dogs from different breeds but also dogs within the same breed but in different age categories may have different appearances of their ERG responses. This may be a problem when evaluating if an ERG is normal or not from a dog within a breed not previously examined. Because of this it is important to obtain normal values for each breed and age group in order to be able to use these for later comparisons of ERGs obtained from individuals affected with various retinal diseases. In this study we have chosen to examine dogs within the three breeds: Labrador Retriever (LR), English Springer Spaniel (ESS) and Chinese Crested Dog (CCD). All of these breeds may be affected with hereditary retinal diseases such as Progressive Retinal Atrophy (PRA). It is possible that ERG-responses vary due to a number of different factors.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).

ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

Aim and questionsThe purpose for this study was to investigate how marks and mark settings are formed in physical training at some compulsory schools. We also wanted to see how the criteria for marks are formed. These were the main questions during this study.? How do the students find the evaluation and the making in physical training?? Are there differences between different student groups when it comes to their experience around estimation and marking in physical training? (gender, marks, schools etc.)? How do the teachers motivate their marking in physical training?? Are there any differences between the criteria for marking between different schools?MethodThe study was carried out during the spring 2005 at eight schools in a municipality in the middle of Sweden. The study involved 339 students opinion polls and 12 teacher opinion polls.

The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

This study focuses the gendered relations of the Military Academy of Karlberg. More specific the study is investigating the experiences among young women and men cadets of suppression techniques. The purpose of the study is to get more knowledge about the work climate and suppression techniques at the officers? training program 2007/2010. The research questions employed for the study were:- Do the women and men officer students/cadets have any experiences of master suppressiontechniques at the officers? training program?- What kind of master suppression techniques occur at the officer?s training program?- What kind of master suppression techniques do women experience?- What kind of master suppression techniques do men experience?The study is a survey and data were retrieved by a questionnaire sent out to the participants.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

In 1990 the education training program for teachers working with children with special needs was changed. One major difference in the new program compared with the former one is that the specialized teacher is now mainly supposed to supervise teachers instead of teaching pupils who have learning difficulties. The aim of this qualitative interview study has been to find out what the specialized teachers think about there education, and how this could influence children with cognitive disabilities in special schools. I have interviewed six teachers who specialized in teaching pupils with cognitive disabilities. Three of them where educated prior to 1990 and the others were educated after 1990.

Fysisk träning för barn har alltid varit ett kontroversiellt ämne som berör såväl etiska och fysiologiska som medicinska frågor. Styrketräning är den form av träning som ställer dessa frågor på sin spets. De svenska officiella organen Idrottens Forskningsråd (IFR) och Riksidrottsförbundet (RF) har genom åren lagt fram rekommendationer och riktlinjer som ska fungera som underlag vid utformning av den träningsverksamhet som bedrivs i idrottens föreningsliv. Eftersom forskningsrön har förändrats i takt med forskningsframsteg har också rekommendationer och riktlinjer från officiellt håll varierat över tid. Syftet med föreliggande studie var att undersöka om fotbollsledare har kännedom om de senaste rekommendationerna vad gäller styrketräning för barn.

Sweden is the country that has got the largest amount of elderly in the adult population in the world. The physical activity level decreases as we grow old and we experience muscle mass loss and a bone density reduction. This leads to an increased risk for falls and subsequent fractures. The purpose of this study was to investigate whether an exercise program could affect muscle function and balance ability to prevent falls. 17 women (age 64-79) participated in this study and was assigned to a control group (n=7) and an intervention group (n=10).

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

The Intensive Care Unit (ICU) is a special unit for patients who is in the need for emergency life-sustaining measures and every patient has complex medical- technical equipment. The experiences of a critical illness and the needs of critical care are experienced in different ways. The purpose of this study was to describe the experiences from patients in the ICU and how this experience has an influence on the patients. The method was a study of literature with a qualitative inception based on eight scientific articles and the analysis of content has been inspired by Graneheim and Lundman (2003). The result of the study is presented by four categories: to loose the ability to make themselves understood, to be forced to adjust to the environment of caring, to have the lack of connection with reality and to be in an intensive care environment, The results showed that patients in the ICU are affected by the attitude from the staff, the equipment around them as well as the sounds and lights in the environment there.

Vid Volvo construction equipment AB, Component division i Eskilstuna, har nedväxling i förpackningsstorlekar genomförts som en del i en omfattande omställning mot Volvo Production System och Lean. Genom att producera med mindre satsstorlekar och hemtagningskvantiteter, vill Component division sänka sin kapitalbindning och bli flexiblare mot variationer i produktionen. Dessvärre påverkar nedväxlingen förpackningskostnaden till följd av ytterligare hantering, transport och administration. För Component division är det viktigt att få en god uppfattning om hur alla förpackningskostnader utvecklas med tiden. De vill i framtiden följa ett lämpligt nyckeltal för att se hur effektiva de är inom förpackningslogistik samt hur beslut och förändringar påverkar kostnaden.
