This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

In July 2011 the journalists Martin Schibbye and Johan Persson are arrested in Ethiopia when on a mission to report the activities of the oil exploration company Lundin Petroleum. Following a trial, closely observed by media, the two journalists are convicted to a prison sentence of eleven years. The Swedish Minister of Foreign Affairs, Mr. Carl Bildt, is now to act on their behalf to preserve their rights as Swedish citizens. However, doubts are raised as to whether Bildt has a conflict of interest because of his former engagements as a board member in Lundin Petroleum.

The main strategy of gender equality policies has since the 1990s been gender mainstreaming. Many government inquiries show how much the Swedish government, provincial governments and municipalities are working with gender mainstreaming. The purpose of this paper is to investigative how the municipalities within the county of Stockholm handle gender mainstreaming demands in relation to other demands that the municipalities face. This is in order to closer investigate the hidden factors that create barriers to gender mainstreaming efforts. Given the study's purpose and the formulation of research question, qualitative method is the most suitable method to fulfill the purpose.

Att upprätthålla en effektiv konkurrens är något som EG-rätten syftar till. Genom artikel 82 i EG-fördraget förhindras dominerande företag att via ensidiga förfaranden utestänga konkurrenter eller begränsa konkurrensen. Det finns flera sätt, för ett dominerande företag, att påverka konkurrensen negativt och därmed göra sig skyldigt till missbruk enligt artikel 82. Ett förfarande som under vissa omständigheter kan anses som missbruk är att leveransvägra för att stoppa eller begränsa parallellimporten. I denna uppsats diskuteras och analyseras det om under vilka förutsättningar en leveransvägran kan anses som ett missbruk av en dominerande ställning.

A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.

As requested by the company Husqvarna AB, we have developed a prototype of an electrical start device to a chainsaw. This was done through the development of new details in Catia, which has been integrated with existing details. Electrical components have been purchased by HAB electronics. In parallel with the modeling calculations was done, which was the basis for determine dimensions and the choice of an electric motor and gears. Prototype 1 improved gradually and led to prototype number 2, which became the final result.

I have analysed the use of portamenti by violinists Janine Jansen, Itzhak Perlman, Jascha Heifetz and Nathan Milstein in the first 8 bars and the two parallel phrases of the Max Bruch Violin Concerto No. 1 in G minor. I have copied their portamenti and recorded myself performing theese phrases in style of each violinist. By doing this I have learnt new ways to use shifting on the violin for expressive purposes and realized how much there is to learn by imitating your predecessor..

Support group activities for children with mentally ill parent´s, without a parallel parent group, is by far the most common form in Sweden. The activities have primarily focused on increasing the frequency of the protective factors around children. Of course, parents and the families are also influenced of children´s participating in these activities. Most studies examining support group activities for children from the child's perspective. The experiences of parent?s perspective have not been well studied.

Trådlösa nätverk är något som växer och breder ut sig mer och mer i det moderna samhället. Allt fler personer har bärbara enheter som kan ansluta till dessa nät. Därför måste de nätverk som inte skall vara publika skyddas från obehöriga. Viktig information kan annars hamna i fel händer. I denna rapport kommer olika trådlösa nätverk och säkerhetslösningar till dessa att undersökas.Genom att använda olika säkerhetslösningar så som kryptering med hjälp av t.ex .

Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.

IDCT (Inverse Discrete Cosine Transform) is a common algorithm being used with image and sound decompression. The algorithm is a Fourier related transform which can occur in many different types like, one-dimensional, two-dimensional, three-dimensional and many more.The goal with this thesis is to create a fast and low effect version of two-dimensional IDCT algorithm, where techniques as multiple-constant multiplication and subexpression sharing plus bit-serial and bit-parallel arithmetic are used.The result is a hardware implementation with power consumption at 19,56 mW..

In game development, performance is everything and the Playstation 3 provides a unique platform for utilizing parallelization of code to achieve extremely high performance. In this master?s thesis the issue of animation with smooth skinning is migrated from being a GPU process to becoming a parallelized and 358% faster process. This method is incorporated in an existing commercial game engine and integrated in a currently in development title for the Playstation 3. An in-depth study covers parallel processors, the CELL processor, used in the Playstation 3, and how contemporary industry leading game developers are utilizing the same unique architecture to increase their own games? performance..

Background: Heart ischemia is a disease affected by behaviour, lifestyle and heredity. The disease is more common in the western world and the number of those who suffer increases. The mortality has reduced thanks to that medical resources and knowledge have approved. Purpose: The purpose of this study of the literature was to find out what patients experienced emotionally at an acute heart attack. Methods: A study of literature where scientific articles has been refereed and analyzed, then resulted into five categories presented in the result.
