Termisk hantering av litium-jon- batterier i elektriska drivsystem
The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Ledare & team utan rätt förutsättningar kan aldrig nå maximal framgång : En studie om tre olika produktionsverksamheter inom Volvo Group
This thesis has been conducted at Volvo Bussar ABunder a period of ten weeks. Within the organizationVolvo, the work is conducted with leaders and teamson every level; from production to top management.They have three tasks, besides executing their dailywork, they are expected to actively work on improvingtheir individual work as well as themselves as persons.The two latter are future value adding activities for theorganization. When doing so, however, it has beennoticed that they often lose the grasp of their dailywork. The question that consequently arises is whythis happens. Is it because of lack of time or it isbecause the co-workers do not have the competenceand simply do not know how they are to execute thethree tasks? Or, is it because the motivation to executethe three tasks is not enough? With this in regard, thestatement of issues for this bachelor thesis were thefollowing: how can the conditions for leaders and theteam be improved, in order for them to execute thesethree tasks.To find out why the execution of these threeassigments did not always succeed, the decision wastaken to conduct a survey and interview study in reallife and at the plants.
Omvårdnad för kalvar med lunginflammation
Pneumonia is a common disease in calves. There are several causes behind the disease.
The main purpose of this litterary study was to estimate what kind of nursing calves with pneumonia could benefit from, especially the evidence-based nursing recommendations for the sick calves. A further purpose was to gain knowledge of different treatments of sick calves and what kind of practical measurements that are most suitable to use in the preventive work.
The results in this study shows that there are only suggestions of nursing, rather than some actual evidence-based actions. The most important nursing actions is to isolate the calves with dyspnea, prevent or treatment of hypothermia, potential dehydration and malnutrition. It is also important to make sure to place the calf on soft and dry bedding.

En kvantitativ studie om lärares inställning till och arbete med Nationella Prov : En enkätstudie i syfte att beskriva lärares uppfattning av huruvida NP bidrar till likvärdig bedömning och ökad måluppfyllelse i mellan ? och högstadiet.
The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.
