Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

ADHD (attention deficit hyperactivity disorder) is a phenomena that is much talked about in both schools and in communities. Today, there is a conflict surrounding the diagnosis ADHD. A part of the conflict takes part between the sociologist Eva Kärfve and Christopher Gillberg, professor in child- and teenage psychology. The roots of this conflict surrounds the much debated line of what is seen as normal and ?too? different, basically how many children that actually should have the diagnosis.

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.

This essay is about the European union freetrade treaty negations with Mercosur. I have in this essay used a qualitative content analysis, to study from the EU perspective the reasons to why, the EU and Mercosur suspended the free trade treaty negations 2004, and after several years resumed the negotiations again in 2010. The purpose of this study is to gain a deeper understanding from the EU perspective of why free trade negotiations were suspended and then resumed. In order to achieve a deeper understanding of this event, I have applied neorealism and neoliberalism on the explicit statements and the implied actions, as these theories may provide different explanatory power of implied causes of negotiations.I have come to the conclusion that the theoretical perspectives can indeed explain explicit statements and implicit actions for suspended and resumed negotiations with Mercosur. The implicit reasons for suspended negotiations are among others that the EU has an egoist thinking concerning a free trade treaty.

The first kindergarten focuses on mathematics, science and technology.

SAMMANFATTNINGPia Carlsson & Carina Lindström"- Hoppsan, här fick jag en timme, vad ska jag göra då?"En undersökning om hur förskollärare tar tillvara tiden med och utan barn."- Oops, here I was given an hour, what should I do?"A study of how teachers in pre-school are taking advantage of the time with and without children.Antal sidor: 39Vi har båda varit verksamma inom barnomsorgen sedan cirka tjugo år och i vår profession samt på våra praktikplatser under utbildningen har vi ofta hört andra pedagoger uttrycka en tveksam-het, inför hur tiden ska räcka till. Tid anses vara en bristvara, arbetsuppgifterna något som stän-digt ökar och vi tycker oss ana en viss oro bland förskollärare för att kvaliteten för barnen ska bli lidande. De uttrycker även oro för uppdragets allt mer administrativa inslag, där "kring"-uppgifter, som inte upplevs som relevanta för arbetet med barnen, betraktas som "tidstjuvar". Därför ville vi undersöka hur förskollärare förhåller sig till tid och deras syn på syftet med pla-neringstid och kvalitetsarbete.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.

In order to stay competitive and to be the first choice for customers in a world driven by a high level of competitive advantage, it is important for companies to stay ahead of the competition by conducting thorough market research. Even if this tends to be the case, many products still fail when reaching the market, leaving companies with great losses. The reason for this could be that the development of existing research methods has stagnated, or that they simply lack the ability to find the true answer as to what intentions underlie consumer?s decision making when shopping. Many believe that a new method is desired in order to get a better picture of what customers really think.
