This is the result of a 10 week long study about if player behaviors and choices are affectedby the surrounding colors in their environment. A number of players are asked to movethrough a virtual environment, while being clocked, where they have to make left and rightdecisions based on different colors (red, green, blue and gray). While most choices consist oftwo different colors, some use the same color. The result shows that the players most likelyprefer one color over another, and that they most likely prefer a non-neutral color over aneutral color. With these results and the interviews that are conducted the conclusion is madethat it is very likely the players choices are affected by the colors in the environment, but it isnot clear to say how they are affected..

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.

During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.

The aim with this thesis, based on five childrens librarians statements, is to highlight their view of their work, and what they deem to be of importance when working with small children within the library sphere. My main question is as follows: What motive compels childrens librarians in their work with small children, and will Vygotskys theories be recognised in their statements. I have two questions as a base for this main question: How do childrens librarians work with small children, and do they utilise any special methods in their work? How do childrens librarians view their work tasks, and what do they deem to be of importance regarding small children and libraries? The thesis is based on qualitative interviews. As a theory I have decided to concentrate on Vygotskys thoughts on imagination and creativity, the Zone of Proximal Development, and childrens language development.

Härdighet för vedartade växter förknippas oftast med zonkartans zonangivelser. Det är dock inte enbart härdighetsiffran som bestämmer om en växt är härdig eller inte. Klimatet på platsen är en avgörande faktor för hur en växt klarar sig eller inte. Via en enkät tog jag reda på vad odlare i Norr- och Västerbottens län tycker om zonkartan och hur de använder sig av den när de väljer vedartat växtmaterial. Nästan alla odlare ställer sig positiva till zonkartans zonangivelser. De påpekade dock brister med användandet av den då den inte tar hänsyn till växtens proveniens, lokalt klimat eller växters krav på odlingsplats vilket är viktiga faktorer som påverkar härdigheten hos växten.

Sarah Kane?s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one?s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

With climate change, the temperature and relative humidity in Sweden are increasing. The majority of historical environments lack protection against this increase, which also increases the risk of mold infestation in these environments. One of these environments is N??s Slott, in which several rooms have recurring mold growth on objects and furniture. By examining one of the rooms in the castle that is in the risk zone or has mold growth, factors behind the mold growth can be investigated in order to create a basis for future actions against mold.

The purpose of this essay is to investigate how parents of children with ADHD or autism experience the transition between preschool and preschool classes. To get answers to my questions, I interviewed five parents representing three different schools in one municipality. I have chosen to use a qualitative research interview inspired by phenomenology. The results of this study show that parents perceptions differ, in terms of how well the transition work for children, and how support and treatment are at a transition. For children with a documented diagnosis, schools have an action plan for those in the gray area there are no procedures.

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.
