I detta arbete undersöktes och jämfördes begreppskoherens och attityd till fysik bland elever på fysik- respektive naturvetenskapsprogrammet vid gymnasieskolan Polhemskolan i Lund. Begreppskoherensen undersöktes med Force Concept Inventory som är ett omdiskuterat flervalstest från USA som ska mäta studenters begreppskoherens för kraftbegreppet inom den klassiska mekaniken. Eftersom många undersökningar visar att intresset för fysik minskar undersöktes också elevernas attityd till fysik med ett svenskt test av Likertmodell. Undersökningarna gjordes på elever som precis börjat åk 1 och på äldre elever som läst kursen Fysik A inom båda programmen. Resultatet av undersökningarna är att eleverna på fysikprogrammet har större begreppskoherens för kraftbegreppet än eleverna på naturvetenskapsprogrammet och att begreppskoherensen höjs efter Fysik A. Attityden till fysik är dessutom mer positiv på fysikprogrammet men eleverna på naturvetenskapsprogrammet har större spridning i attityd.

Dimensional stability is an important aspect of fuel mechanical design and licensing of new fuel designs for nuclear power plants. Dimensional changes within the reactor can affect the safety margins against overheating of the cladding and the pellets, therefore it is crucial that the dimensional changes are kept to a minimum.The profits per produced kiloWatt hour continue to decrease for the Swedish nuclear power plants. Some reactors are even operated with a calculated loss. To reduce fuel costs and thereby improve the profit some reactors are operated with higher uranium enrichment, so that the assemblies can reach a higher average burnup. This increases the neutron fluence to the pellets, cladding an spacers.

This study reflects on the swedish model and the models future. The swedish modelmeans that legisilation acts with the collective agreements . The wage issue is notregulated by law instead it is managed by the social partners in the form of collectiveagreements. In 2008, a report was presented by the Commission on a joint regulation ofthe minimum wage for all EU countries. The issue has become increasinglycontroversial and was especially disccused for the election of candidates to theEuropean Parlament last spring.

I chose to study how the Swedish Air force carries out their work with setting goals for their work to improve flight safety and compare this with how the Swedish nuclear power plant Forsmark performs their work with improving nuclear safety. The study showed that both organisations have a lot to improve on in their ways of how to work. Especially when it comes to engaging the employees in the process, both in letting the employees be a part of coming up with areas to work on and in letting the employees evaluate which progress that has been made. It also showed that both organisations need to improve their methods for evaluating the work that has been done. This is especially important for the Air Force which evaluates on many levels and locations and did not have a set standard for how to conduct the evaluation.

One of the big challenges for the European Union today lies in finding a common foreign policy for its 27 sovereign member states with their divided interests, experiences and traditions. New objectives set requirements on the Union to develop and intensify its military ability. The European Union´s view on when military force can be utilized sets concepts like sovereignty and intervention in focus. Can sovereignty be limited and if so can an intervention be justified? How did the Union argue regarding its participation in the intervention in Afghanistan, 2001? The Just War Theory gives the essay a normative framework against which to assess the Union´s view and guidelines for the use of military capabilities.

The projects goal is to construct and program a robot that is controlled from a computer but also have an obstacle handling function that allows the robot to navigate around the object by itself.The robot is a simple construction and the number of components and functions is kept at a minimum. A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..

Benchmarking is an established method of working which is often used in order to develop the quality of the organization. However, almost 70% of the organizations with benchmarking fail due to the lack of planning and structuring of the benchmarking exercise. Maintenance sections in the paper and pulp industry are one of those who have decided to conduct benchmarking. Therefore, the purpose of this study is to gain knowledge of how the maintenance sections in the paper and pulp industry deliberately structure and plan to use benchmarking as a driving force for quality development in the maintenance sections.The study is a hermeneutic case study. Telephone interviews and document analysis have been used as data acquisition methods.The results show that there is a lack of both planning and structuring in the benchmarking process, and lack of management commitment for quality improvements within industrial maintenance.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

The technical development is advancing at high speed and now the turn has come for the traditional paper to digitalize into the so called e-paper. The newspaper industry has started to investigate the future possibilities of publishing the traditional newspapers on e-paper. Today?s newspapers are mostly financed by advertisement incomes, which makes the advertisers important players, who must be taken into consideration at an introduction of the e-paper. Since the e-paper does not exist as a finished product in the market today, in this essay we look into what kind of functions or services that can attract advertisers to the e-paper on the basis of the experiences made with the breakthrough of the web-newspapers.

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

Det har inom krigföringen skett en utveckling mot riskfri krigsföring där västliga stater, och då främst USA och Storbritannien är de främsta representanterna. Denna typ av krig är ett resultat av en kombination av (1) minskad inhemsk tolerans för förluster i krig och (2) en teknologisk utveckling inom militären. Denna typ av krigföring har kommit att kallas spektakelkrig och uppvisar en oförmåga att leva upp till kriterierna för att ett krig skall vara rättfärdigt; spektakelkriget har dels svårigheter att startas med en rättfärdig orsak (Jus ad Bellum) och dels att sedan föras rättfärdigt (Jus in Bello) i linje med vad teorin om rättfärdiga krig stipulerar. Jag har funnit bevis för detta genom att undersöka tre sentida, västliga operationer som samtliga har resulterat i krig och där samtliga fallerar på en eller flera av kriterierna för rättfärdiga krig. Operationerna är operation Desert Storm, operation Allied Force, operation Enduring Freedom..

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

The main aim of this thesis is to examine what motivates people to become entrepreneurs and how they are motivated to continue being it. We have decided to focus on four elements: the driving force of being an entrepreneur, the environment, the individual background and important personal characteristics of the entrepreneur. Qualitative interviews were carried out with six information consultants. The theoretical background has its focus on entrepreneurial motivation. A model of entrepreneurial motivation by Naffziger, Hornsby and Kuratko 1994 is presented.
