The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.

Sammanfattning Eftsom kalla Sverige blir mörkt ganska tidigt på kvällen på höst, vinter och vår ville jag se hur man kunde förlänga användandet av det lilla trädgårdsrummet både i tid på dygnet och i tid på säsongen. Jag tycker att ljussättning är en viktig del av gestaltningen, belysningen gör trädgården levande. Mitt syfte med arbetet var att skaffa mig grundläggande kunskap om ljussättning och ljuskällor, för att sedan skissa på koncept för det lilla trädgårdsrummet. För att lyckas med detta behövde jag ta reda vad ljus är och hur det fungerar. Ljuset har många olika egenskaper, t ex olika våglängder, och färger.

Följande rapport beskriver teori, metod och resultat av ett examensarbete vid Luleå Tekniska Universitet utfört i samarbete med Light My Fire AB. Företaget tillverkar produkter som används av människor i hela världen och som ger användaren ett leende på läpparna. En produkt som har saknats i sortimentet är en vätskebehållare och flera återförsäljare världen över har frågat efter just detta. Målet har varit att ta fram en multifunktionell vätskebehållare som ska passa in i Light My Fires befintliga sortiment och få plats i företagets produkt, LunchBox. Projektet började med en grundlig benchmarking för att ta reda på vilka olika typer av vätskebehållare som finns.

The master thesis deals with three completely different areas: the place, the light and the design, which all are parts of the subject landscape architecture. The Place in this paper is the graveyard, the Light is the artificial and the Design is an illumination. The common denominator is the graveyard at Galärvarvet in Stockholm, Galärvarvskyrkogården, where the three parts meet in a clear and outspoken need of new lighting. The problem formulation is: Is it possible for a graveyard to be looked upon and used as a park? How do the administrators and the designers reason in this matter and what are the consequences for example the illumination at a graveyard? This is being investigated and discussed in general and thereafter the thesis is specifically focussed on the needs and solutions for the graveyard at Galärvarvet. The thesis, which is mainly based on facts from litterature, location studies and interviews, contains of pure parts of fact, discussion parts, different types of analyses, reflections of the author, illustrations and photos from the graveyard at Galärvarvet and also a lighting proposal for the graveyard and its close environment. The purpose of this work is to show the connection between the usage of the graveyard and its illumination. All to simplify for the administrators, planners and designers. Hopefully this thesis will be of use in the deciscion making process for future lighting projects for the graveyard administration in Stockholm as a basis for their discussion and decision process for future lighting projects..

Cyanobacteria belong to the oldest organisms of our planet. They use photosynthesis to produce ATP and gain biomass from carbon dioxide. The cyanobacteria Nostoc punctiforme is a filamentous bacterium that consists of two different types of cells, vegetative cells and heterocysts. The type of cell it differentiates into depends on the media they grow in. In an ammonium-rich medium, the N.punctiforme consists of vegetative cells that differentiate into heterocysts when in the medium is changed to a low-concentration ammonium medium.

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.

The question of euthanasia has kept pre-occupying and agitating the minds of thinkers, sweeping the globe, pummelling pedagogy, assailing assumptions, and bludgeoning biases. Both the moralist, ethicist, theologian, psychologist, educationist, anthropologist, politician, physician, patient as well as the common man in the street are interested in it. This pervading interest simply arises out of the fact that euthanasia involves the question of life, and life is something that is a common denominator to all men.The controversy hinges on the fact that, there are divergent views on the moral question of euthanasia. While some would unflinchingly opt for euthanasia others would prefer to oppose it to the best of their strength, yet others will remain agnostic about it. But the issue here remains: is euthanasia in any way morally justified? Has human life an intrinsic value? Or is human life valuable only when it is healthy? Are we the ones who decide when to die? Has the physician any right to either assist or terminate the life of the patient simply on account of suffering? Has the patient any right to end his/her life? Are there some conditions in which euthanasia could be allowed? Is suffering meaningless?The topic of my project is: THE MORALITY OF EUTHANASIA IN THE LIGHT OF THE CATHOLIC CHURCH?S TEACHING.

Jag skall i mitt projekt först och främst få erfarenhet av hur det är att samarbeta som designer med ett företag och även få ut en produkt som är klar att använda och som skall kunna säljas i butiker runt om i landet. Den skall följa företagets riktlinjer, vara energisnål och vara funktionell men samtidigt tilltalande..

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.

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.

Badminton är en inomhussport som människor i alla åldrar och på alla nivåer kan utöva. Ju högre nivå sporten utövas på ju mer krav ställs på belysningen. I många badmintonhallar används idag armaturer som bidrar till bländning och som inte ger en god synkomfort. Badminton är världens snabbaste racketsport vilket gör att kraven på belysningen är hög. Utan tillräckliga riktlinjer gällande belysningsanläggningens utformning som ska säkerställa en god belysning för spelarna kan det bli svårt för dessa att hinna uppfatta fjäderbollen, då spelet går väldigt snabbt och mycket rörelser sker på badmintonplanen.Syftet är att öka förståelsen för vilka faktorer som är viktiga att ta hänsyn till vid planering av ny belysning i badmintonhallar.Metoderna som användes i studien var observationer, ljusmätningar, intervjuer och enkätundersökningar.

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.

This thesis describes how the development of a mechanical enclosure to an alarmsystem proceeded. The project was made on behalf of Inferno Light Indusec AB.The goal set to this housing would offer a home alarm in which Indusec?s uniquesound system would give the customer a new alternative on the market. They wantedto, among other things, create an aesthetically but at the same time affordable alarm.The aesthetic theme is something that is missing in today?s market.

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.

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.
