?ÄNTLIGEN!?- En lysrörsarmatur för det egna hemmet
The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.
Betydelsen av taggbuskar, ljus och hävd vid föryngring av ek (Quercus robur)
Many species and hence biodiversity depend on old, large oaks (Quercus robur) with hollow trunks. The populations of oak-living organisms have to migrate to a nearby old oak in order to survive the death of the host. The oak district south of Linköping, Sweden, is unique in area and the number of old oaks. It is anyway doubtful whether regeneration of oak will secure future continuity. Oaks are light-demanding and thrive in open pastures.
Trauma and coping - A study of women that were trafficked for the purpose of sexual exploitation in India
This study was conducted in the red-light area of Pune city, India. The target group of the study is sex workers that are victims of human trafficking for the purpose of sexual exploitation. The purpose of this study was to examine the initial and continuing trauma and its effects, and the coping strategies that these women develop in order to survive. The initial trauma occurs during the trafficking and seasoning process in the brothel. The term continuing trauma refers to violence and psychological trauma that are part of sex workers lives.
Evaluation of the retinal ON- and OFF-responses in the dog ERG
The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from
their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background.
This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response
(Frishman, 2006; Zrenner and Gouras, 1979).
In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones.
These stimuli gave ERGs with both ON- and OFF-responses.
Färgkonnotationer i spel : Hur val av färg påverkar hur vi upplever en spelkaraktär
The purpose of this bachelor thesis is to identify the relationship between color and semiotics and how a person?s opinon, regarding a game character?s different characteristics, can be affected by the use of various colors. Prior to this study people were asked, through an online survey, to write down words that they associated with different colors. The colors were then divided into four different groups depending on whether they had been associated with positive-strong words, positive-weak words, negative-strong words or negative-weak words. In order to further shed light on the effect of colors, the four palettes, consisting of the colors associated with the different words, were then used separately to give color to two characters: a man and a woman.

"Från mörkret stiga vi mot ljuset". Den socialdemokratiska memoaren som retorisk genre: exemplen Palm, Erlander och Persson
Although Social Democratic Memoirs comprise an extensive material, these texts have not attracted any systematic analysis as a distinct and yet varied form of textual genre. The focus in this MA-paper is the Swedish Social Democratic Memoir as a rhetoric genre. The main primary material is memoirs of the pioneer August Palm (1849?1922), the father of the nation Tage Erlander (1901?1985) and the political leader Göran Persson (1949?), published 1905, 1972?82 and 2007, respectively.The general aim is to find out what is the driving power of the memoirs and, more specifically, to shed light on the images of the party history and the history of the welfare state. The method is a comparative analysis of these texts.
Rättigheter och skyldigheter i grundlagarna : I ljuset av den politiska filosofin
The purpose of this essay has been to compare different constitutions, and their outlook on citizenship, rights, obligations and natural duty. This has been done in the light of the political philosophy, in order to give the answer to four questions. These questions are: Which rights and obligations can be seen in the constitutions, and how can it be interpreted. Can there be signs of any political philosophy in the constitutions? Are there any differences between the constitutions regarding citizenship, rights, obligations and natural duty? If so, what are the differences? Can the rights be seen in a further extent than the obligations in the constitutions?I have conducted a qualitative comparision study and analyzed the political philosophers and made a classification scheme of their views.
Det ännu icke sedda : ett undervisningsexempel från äldreomsorg
With examples from a single classroom situation, several educational moments show what goes on between the teacher and the student. The teacher?s responsibility in the learning process is, with a gesture frozen in the air of the moment, to lead and follow the student in her tentative efforts at seeking knowledge. Initially, it is an attempt to shed light upon the "not yet seen" with a certainty that the student herself possesses the capacity and the aptitude to reach greater insight and clarity in her understanding. The Validation/Feil Method presented in this instructional situation illustrates how best to communicate with elderly people suffering from Alzheimer?s dementia.
Parametrar för materialanskaffning
Denna rapport är ett resultat av att System Andersson vill utreda uppbyggnaden av deras materialplaneringssystem. System Andersson har valt att dela upp systemet i ämnesområden till flera olika projektgrupper, där författarna till denna rapport ska ge förslag på parametrar för att genomföra materialanskaffning. Målet med de framtagna parametrarna är att materialplaneringssystemet ska generera inköpsförslag, där det tydligt ska framgå vad som ska köpas och vad som ska tillverkas. Författarna ska ta fram två olika lösningsförslag, Light och Advanced. Syftet med denna uppdelning är att systemet ska anpassas till olika kundsegment. För att ta fram parametrarna har en litteraturstudie och en kundundersökning genomförts. Litteraturen som har använts är tidigare kurslitteratur samt annan litteratur inom ämnesområdet för att validera kurslitteraturen.
Clash of Civilizations Myt eller verklighet?
In 1989 the Cold War ended and in 1991 the Soviet Union ceased to exist, over night the ruling paradigm of International Relations was obsolete. What would happen now? Samuel Huntingtons answer was that in the future, cultural identity would be the most important factor behind international conflict. And that the threat of world war would come from clashes between civilizations instead of clashes between ideologies like during the cold war. Was he correct? This thesis is an attempt to find out if Huntingtons theory was right in its predictions of the world to come.
"Natten är dagens mor": Lars Noréns pjäs tolkad utifrån ett vetenskapligt och systemteoretiskt perspektiv
Our purpose with this essay was to analyse the play "Night Is the Mother of Day" written by Lars Norén, and to investigate how the family members/characters in the play interacted.By analysing the family with help from the system theory and by comparing the family with scientifically proven facts regarding drug abuse complexities, this essay explains the family's behaviour pattern and main dysfunctional problems.This essay explains the similarities and non similarities between the science and the specific theatrical play being used. It also rise the question whether there are advantages with analysing plays in terms of increasing the ability to relate to difficult problems and create a greater empathy and understanding for people involved with social problems..

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med hjälp av UV-ljus och ozon
This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.
