This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.

The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

The purpose of this study was to identify reading strategies used by high school students when reading textbooks and school-related material. Any differences in reading strategies between Biology and English were also of importance. A study sample of 62 students from three different high schools in Sweden participated in the study and were asked to fill out a survey questionnaire. Eight students from this sample were also interviewed. The findings of this study show that students use a number of different reading strategies of which metacognitive and sociocultural factors play a crucial part.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Abstract- Stress, conformity, groups and self-worth in high-school girlsThe aim of this questionnaire-survey was to investigate the experience of stress and symptomsof stress in high-school girls, and to examine if the experienced symptoms of stress could bepredicted by groups, self-worth and conformity. Another purpose of this study was to describethe girls own thoughts concerning these factors. 80 girls between the ages of 15-18 yearsanswered the questionnaire. The results showed that stress could be predicted by theexperience of conformity, but not by the experience of belonging to a group and self-worth.The most common symptoms of stress were tiredness, problems to concentrate and headache.The girls reported that they thought that girls of their own age were ?slutty and cocky?, andthey thought that it was important to look good, but at the same time many girls were happyabout themselves and they had realised that they had to live with who they are.Keywords: high-scool girls, stress, groups, self-worth, conformity.

In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

Material handling is a term that includes all kinds of handling of material from a raw product to a finished one. ABB is active in the following segments; foundry, packaging and palletizing, metal industry and plastics industry.The demands for efficiency and reliability have been set very high in the industrial sector. Optimizing of the material handling will give the company higher cost-effectiveness. Around the robot there are different kinds of material flows, to optimize the cycle time, consisting of carriages combined in different ways.Motion Control is a complex system with main functions such as; positioning, synchronizing, indexing and more. The products in the system need to cooperate to make these functions possible therefore integration of motor- and servo products are important.

Who would not like a profit of more then 95 % in a day? Investors in Sweden had thatopportunity, if they had bought a certain stock on the primary market and sold it on the firsttradable day at the Stock Exchange. Most of that profit fell into the hands of institutionalinvestors. The reason for this extraordinary profit was the underpricing of that specific stockduring its initial public offering (IPO).Our report aims to analyze the relationship between offer price, underpricing and theownership structure of stocks. Our investigation is based on all IPO?s on the Stockholm stockexchange during the years between 2000 and 2005.
