Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

The purpose of this study has been to examine different aspects of the professional role of the high school librarian, especially the educational role, and its delimitations to the teacher's role. The methods that were used were studies of literature within the subject area and qualitative interviews with high school librarians and high school teachers of social studies. Andrew Abbot's theory on the system of professions was used in the analysis of the results of the study. The high school librarians who were interviewed enabled access to information, both intellectually and physically. They helped students develop information seeking skills and they functioned as educators and counselors.

Projektet har undersökt om medveten motorikträning ger några eventuella effekter un-der en sjuveckorsperiod. Projektet ger en bild av hur barns motoriska förmåga kan för-bättras under denna relativt korta tidsperiod. Två barngrupper med 12-15 barn/grupp deltog i projektet, en grupp med fyraåringar och en grupp med femåringar, Under pro-jektets gång hade barngrupperna vars en timme varje vecka under en sjuveckorsperiod som ägnades åt medveten motorikträning med fokus på momenten springa, hoppa och krypa. Vid första och sista tillfället observerades barnen med utgångspunkt i ett obser-vationsschema som skapats med inspiration från MUGI observationsschema (Ericsson, 2005). Projektet visar att medveten motorikträning under en sjuveckorsperiod ger viss utveckling av barns motoriska färdigheter när det gäller att springa och hoppa.

Every year, reports are published that shows how universities fail to meet the demand from companies who are looking to hire students with solid communication skills. At the same time, the importance of communication for effective leadership is constantly increasing. Today, many business schools around the world states that they strive to educate future business leaders and have therefore realized the importance of teaching the skills of communications to its students. The majority of Swedish business schools, however, have not yet made communications an essential part of their curricula. This indicates that most business students in Sweden today, do not receive the toolkit needed to take on leadership roles.

De finmotoriska förmågorna är oerhört viktiga vad det gäller den mänskliga läs- och skrivförmågan, då handen behöver vara tränad för att göra små rörelser och ögonen ska kunna följa dessa rörelser. Barn som har svårigheter med de finmotoriska förmågorna blir beroende av andra, då de kan få svårt att klara av vardagliga bestyr så som att klä på sig själva och använda bestick. Något som försvårar arbetet med de finmotoriska förmågorna utomhus är att barn använder vantar stora delar av året och att tillgång till materiel som utmanar handrörelser plockas fram mer sällan under vinterhalvåret på grund av kylan. Detta gör att barn inom I ur och skur-förskolor som oftast är ute får mindre träning av de finmotoriska förmågorna under kalla årstider. Vi har jämfört I ur och skur-förskolor med förskolor utan den inriktningen, vad det gäller arbetet med de finmotoriska förmågorna.

The aim of this bachelor?s thesis is to develop knowledge about how librarians experience their professional identity, argue for their competence and describe their profession based on their professional skills, tasks, and status. The method that is used to answer the questions of the study is semi-structured interviews with five public librarians. The theory used in this essay is Ørom?s six librarian identities plus Schreiber?s experience intermediate identity.

Syftet med undersökningen var att studera pedagogers upplevelser av barns motorik i förskolemiljö. För att fördjupa samt tydligare beskriva syftet valdes några frågeställningar ut: Hur upplever pedagogerna motorikens betydelse i det sociala samspelet? Hur upplever pedagogerna motorikens betydelse i lärandet? Vad kan pedagogerna göra för att hjälpa barn med den motoriskautvecklingen? För att undersöka studiens syfte användes kvalitativa intervjuer, som genomfördes med fem stycken verksamma pedagoger i två förskolor. Resultatet visade att pedagogerna har olika erfarenheter och upplevelser av begreppet motorik, men att pedagogerna gemensamt lyfter vikten av motorikens betydelse för barns utveckling. Studiens slutsats är att pedagogerna samt tidigare forskning och litteratur lyfter motorikens betydelse för barns fortsatta utveckling.

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.

National and international studies, such as PISA and TIMSS, which are part of the national evaluation system, are carried out continuosly. Skolverket, in collaboration with researchers, are responsible for the implementation, evaluation, and analysis of the studies. National results show an increasing percentage of pupils who do not reach the goals in mathematics. The last completed international studies PISA 2009 and TIMSS 2007 show an impaired trend of knowledge, in international comparison. Moreover, studies also show that the differences between schools and also within the same school in Sweden have increased.
