Träning av lexikal förmåga hos ett svensk-arabisktalande förskolebarn : Utredning och intensiv intervention av det svenska ordförrådet

Sweden has a growing proportion of children living in a multilingual environment. It is thus highly important that caretakers as well as professionals who meet these children have knowledge of multilingualism and its impact on language development. Also, an increase of referrals of multilingual children with suspected language impairment to speech and language pathology clinics is seen.The objective of this study was to investigate the linguistic ability in both Swedish and Arabic in a four year old child with suspected language impairment. A further aim was to implement an intensive intervention and evaluate the efficacy of it. Language testing in both languages showed that the boy?s greatest need was in the lexical domain.

Från digitalt utanförskap till digital gemenskap : En hypotetisk väg till digital gemenskap

We are in an emerging digital society where we are increasingly dependent on the mastery of IT and digital technologies to better carry out our everyday tasks. They cover everything from keeping in touch with family and friends to pay bills and declare. At the same time there are those who have not learned how to use the new technology and live their lives outside of the digital society. What happens to these people, in a society that is becoming increasingly digitized? Do they take harm by being in digital exclusion? It looks like this are issues that will not become less important as digital technology constantly changes.

Blödningsbenägenhet hos bengalkatter :

During the years 2005-2007 several cases of abnormal bleeding were seen after surgery in Bengal cats on veterinary clinics and animal hospitals in Sweden. In this study we have examined if the observed bleedings are due to an inherited defect of the coagulation cascade. Ten Bengal cats were tested for activated partial thromboplastin time (P-APT-time) and one-stage protrombin time (P-PK), and nine of these cats were tested for fibrinogen quantity (P-fibrinogen). Four of the tested cats had shown signs of an abnormal bleeding after surgery, and five of the cats were genetically related to these cats. One cat had a small bleeding wound at the internal base of the right auricle.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

The change of haemoglobin during blood donation, and an assessment of a photometrical method for non-invasive haemoglobin analysis

In Sweden, lowest acceptable haemoglobin levels in blood donators are 125g/L for women and 135g/L for men for a test sample taken in the beginning of the blood donation. Levels, which are 10g/L lower, are accepted if the sample is taken after the blood donation. Earlier studies show that the haemoglobin level decreases for a person that is lying down.The two aims of this study were to examine how much the haemoglobin levels change during blood donation and to examine if the photometrical instrument Pronto-7TM shows equivalent results to that of the established method Cell-Dyn Sapphire.In the study, 120 blood donors participated. Blood samples were taken in the beginning and in the end of the donation. Analyses by Pronto-7TM were done before and after the donation.The haemoglobin level decreased significantly during the blood donation.

Alternativ till fortsatt elektrisk generering i Olidan

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Automatiserad laddning och plundring mellan magasin

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

Den teoretiska utmaningen - En undersökning om nyinstitutionalismens (o)förmåga att förklara förändring.

This thesis aims to examine the possibility of understanding social change by using new institutionalism approaches on a specific case, The case, which describes the implementation of new public management reform in the Swedish health care system, is analysed from two separate new institutionalismperspectives; the tool perspective and the symbol perspective. These approaches differ from one another in the sense that the first relies on a rational choice ontology, while the latter rather refers to a sociological tradition. In the analysis, causal explanations as well as aim related explanations are presented. Formative moments such as economic stagnation, non-socialist governments and ideological isomorfism are presented as important factors behind the reformation. By using the tool perspective, the motives of the idea spreading and reformation of the Swedish health care system, are connected to a strictly rationalbasis such as cost efficiency and quality improvements.

Kulturen bakom kulturen - En komparativ studie av kultursynens inverkan på tyska och svenska kulturpolitiska strukturer

This thesis aims to develop a theory in the under researched field of international comparative cultural policy studies. lt does so by combining theories from the fields of political scienceand cultural studies, researching how and to what extent the concepts of culture of different states have an impact on the way cultural policies are constructed.The thesis uses this theoretical development in order to research a specific problem, namely the perceived possibility that Swedish and German cultural structures are slowly converging. Two recent official policy documents from each country are the objects of study. Through comparative idea analysis and with Michiel S. D Vries theories on decentralization, the thesis explains the convergence between the countries by differing cultural views between them.

Leder icke användarcentrerad systemutveckling till låg användbarhet?

Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.

Spänningsanalys av axel-länkmekanism på borr-rigg

This master thesis is intended to give an increased understanding of the stress state in an axle, which is assembled in one of Atlas Copco?s mountain drilling rigs. The main problems investigated were how the axle is affected when the bearing is worn, when the pretension is varied, and how to dimension the axle. Answers to these questions were found by using hand calculations, practical testing and with Finite Element analyzes. The dimensioning of the axle is currently based on the bending stress, but the author?s opinion is that the axle should be dimensioned considering the equivalent stress.

Förbättrad muskelfunktion och balans hos äldre kvinnor efter sex veckors funktionell träning

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).
