There is a constant change in the world of school, new curricula and syllabi are made and the view of teaching and learning is changing. The desire to improve maths teaching in Swedish schools is strong, especially by laboratory work. How is it then that several teachers in our schools are still using the traditional way of teaching mathematics, which I consider to be relying a lot on the textbook and work for an automated approach?The purpose of my study is to investigate how three different math teachers on an F-5 school in the southern Stockholm area, choose to work with mathematics and why they choose to work according to a special approach. In order to obtain the information I seek, I have chosen to use the qualitative method to get a better understanding of my results.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

SammanfattningSyftet med studien är att undersöka ungdomars upplevelse av trygghet respektive otrygghet i det offentliga rummet i Skärholmen, samt vilka strategier de har för att öka trygghetskänslan. Studien intar ett genusperspektiv och bygger på forskning och teorier om trygghet, otrygghet, genus och offentliga rum. Genom ett bekvämlighetsurval kontaktades sex respondenter och semistrukturerade, kvalitativa intervjuer genomfördes. Resultatet visar att ungdomarna generellt är trygga i det offentliga rummet i Skärholmen, särskilt på välbekanta platser, på platser där de känner många människor, samt på dagtid. De mest framträdande faktorerna som ligger till grund för upplevelsen av trygghet är kunskap och erfarenheter, kontroll och samhörighet.

Currently there is a tendency in the EU to adjust the minimum-capital requirement. In France and Germany the requirement for private limited liabilities has been totally abolished, whilst other countries have chosen to reduce their requirement. The Swedish law concerning the minimum-capital requirement is from 1st of April 2010 being lowered to 50 000 SEK. In common law jurisdictions such as United Kingdom and USA a minimum-capital requirement does not exist. The european main argument to keep such a requirement is that it accomplishes a creditor protection.

The purpose of this examination was to find how supervisors interpreted the termsvocational identity and vocational culture, found in the diploma goals in workplace-based learning at the Child- and Recreation Programme. To reach the purpose, I formulated questions that I answered through a qualitative study. I made six interviews with pre-school teachers who had been supervisors for students at the Child- and Recreation Programme. The informants answered the same questions and the answers were recorded. The result of the study showed that the supervisors made a fairly consistent interpretation of the terms.

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.
