Turbomotorn har funnits med oss i många år nu. Den har länge förknippats med kraftfulla och dyra sportbilar. Men eftersom utvecklingen har gått framåt och priserna på turbotekniken sjunkit har de letat sig in i vanliga personbilar. Detta är inte bara för att höja statusen, utan också för att turbon faktiskt ger en effektivare motor. Turbon utnyttjar spillvärmen i avgaserna för att driva en kompressor som i sin tur tvinga in mer luft i förbränningsrummen.

Stock lending is primarily a professional activity. The supply of stocks in the lending market comes mainly from pension funds and insurance companies, while intermediaries provide valuable services by taking positions as borrowers as well as lenders. Borrowers use stock lending for various reasons. For instance, hedge funds usually borrow stocks to cover a short position. There has been a lot of controversy in the stock lending industry and the debate has mainly concerned its effects for the stock markets.

Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

The aim of this studie is to describe, analyse and understand the benefits and disadvantages with using digital tools in education. In my qualitative method three primary school teachers were interviewed about how digital tools should be used in educational purposes, also what benefits/disadvantages they could see with the investment of digital tools in their school. I also did observations in two classrooms and interviewed a school politican to get a wider perspective. The collected information identifies that some benefits of using digital tools is the contribution to a more equivalent education, more opportunites for cooperations and that fewer pupils have to struggle with their fine motor skills when producing a text. Some of the disadvantages with using the tools is that they breaks sometimes, it´s easy to get dependent and if something happens (like power outage) it´s unusual that schools have a good an action plan.

When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.

AbstractDuring the last decade the public sector has been influenced by new ways of measuring performance and governing, taking inspiration from the private sector. The Swedish municipal community Vellinge has since 2004 adopted ?The Balanced Scorecard? by Kaplan & Norton, measuring not only the financial parts but also other, important factors. The adoption took place since the Swedish government applied new demands on county councils and municipal communities through ?God ekonomisk hushållning?.

För att kunna styra en motor krävs bland annat ett tändsystem. Detta tändsystem måste klara av att ge rätt energimängd vid rätt tidpunkt. Mekaniska och tidiga elektroniska tändsystem som konstruerats är inte tillräckligt effektiva. För att få möjlighet till enkel men bättre optimering av effektivitet konstruerades ett kapacitivt tändsystem. Detta system använder en mikrokontroller som beräknar tändfördröjningen.

The aim of this study was to gain understanding and knowledge about first line manager?s need for support in their leadership and to get more insight into how they handle and perceives their work.The research method is based on studies of relevant theories and qualitative interviews. Eight respondents were interviewed with a structured 40 question questionnaire about how they experience their work and the support they get. The study shows that there are three important categories of people that are most significant to the managers in their need of support. They are their own manager, colleagues and co-workers.The conclusion is that it is important to create conditions for leaders to have good relationships with their closest manager, colleagues and co ?workers.

AimTo validate the STOPP-8-questionnaire (S8Q), containing items from the SIH-questionnaire, against the criterion method accelerometry to estimate its capacity to assess 8 year old Swedish children?s physical activity (PA). Can it assess children?s physical activity? Can it differentiate the active children from the sedentary? If the answer is yes, how well can it do so? MethodData was collected during fall and winter the school year of 2008 - 2009 via the project STOPP-8. Out of 676 children at 12 schools in Stockholm area, 155 (boys n=72, girls n=83) provided complete questionnaire data and wore an accelerometer (Actiwatch 4) during 7 consecutive days which provided data for mean and median activity, time spent sedentary, in moderate to vigorous PA and vigorous PA.

Målet med detta examensarbete var att utveckla en fungerande prototyp för styrning av ett portabelt filter med varvtalsreglering och tidräkning. Om möjlighet fanns, skulle även tillval som tryckstyrning, gasindikering och flödesmätning göras. Dessa tillval kunde regleras med hjälp av fyra knappar. För att allt skulle vara lättare att hålla under uppsikt, kunde alla inställningar och värden ses på en LCD-display. Konstruktionen består av en mikrokontrollerstyrd elektronikkoppling med extern realtidsklocka för drifttidsräkning.

Purpose: The aim of this thesis has been to study and obtain greater understanding of the consequences of active social media use. Specifically, in terms of social identity, social life and the sense of belonging. Secondly, the thesis studies the consequences of disconnecting and for a limited amount of time opt out of the social media context.Method/material:  The study is based on an explorative, cultural ethnographically-inspired method, in which four respondents were studied: two men and two women, all frequent users of social media. This was done in three steps: initial interviews, followed by social media diaries and finally a focus group. By allowing these methods to complement each other, the goal was to create an overall picture of the importance of social media in their everyday lives.The study's focus lies on the week in which the respondents kept social media diaries.

In this work, I have studied whether if one can detect AD / HD in preschool. I have read some literature and searched on the Internet. I have also tried to get to interview people who are familiar with this topic, which has not been easy. I have questioned 13 persons if they would participate in an interview, but most have refused because they do not have time. I succeeded anyhow to get three persons, two special educators and a nurse on the BVC.
