The cow eye-Function and effect of light on milk yield

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.

A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.

Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :

Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA. This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads. Cumulative effects include both direct and indirect effects.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Hållbarhetsredovisning enligt GRI:s riktlinjer ? En studie om noterade bolags redovisning

I dagens samhälle finns ett stort fokus på miljö och att företag ska arbeta med hållbarhet. Efter flera uppmärksammade skandaler har kraven på företagens hållbarhetsarbete ökat. Corporate Social Responsibility (CSR) är ett av de mest förekommande begreppen inom hållbar utveckling och består av tre perspektiv ekonomiskt, socialt och miljömässigt. Hållbarhetsredovisning är frivillig och det finns flertalet organisationer som tagit fram principer och riktlinjer till företagen. En av de större organisationerna är Global Reporting Initiative (GRI) som tagit fram ett ramverk för hållbarhetsredovisning.

Exponera mera : ett arbete om skyltning på bibliotek

This Master s thesis deals with the display of library media, whether it is conceivable and desirable to draw inspiration from the retail business when displaying articles. The questions asked are: are there, in the retail sector, well established display ideas and - if so - what do they look like? Are the similarities in conditions, between the branches, sufficient? In conveying the ideas to libraries, are the potential differences not obstructive? Is there, among librarians, a positive attitude towards further development of library display techniques? The results were achieved by interviewing shop window dressers and librarians. In addition, a survey was sent to the library managers of 65 public libraries in southern Sweden. The results show that there are established ideas and methods of displaying materials, and that the ideas are manifested in frequently used techniques.

Miljöpartiet - ett parti i förändring : En komparativ textanalys av Miljöpartietspartiprogram mellan 1994 och 2005

Following changes in society and other influences, the ideology of political parties can evolveover time. For example, theories exist claiming that all parties in Sweden strive towards the"middle".A good example of a political party in Sweden which recently has gained entry toparliament is the Swedish Green Party (Miljöpartiet, MP).MP was initially influenced by a green ideology (ecologism) which started as a globalmovement stating that no other ideologies shared their concerns about the environment. Thegoal of the ideology was to, via an increased influence within the political system and throughsmall-scale production, increases both natural values and people's well being. By becomingelected into parliament it is plausible that the ideology of MP could have changed due to theinfluence of for example, the realities that parliamentary every day represent.The aim with this essay was to study the changes in MP's party program from the yearof 1994 and the most recent, to see if any changes have occurred related to MP's officialideology. The study was conducted using a comparative text analysis.

Kontraomvändelse - blivandet av en ateist : en religionspsykologisk undersökning av byte från religiöst orienteringssystem till ateistiskt

The purpose of this study in the psychology of religion is to explore the process of an individual?s shift in orienting system, from a religious to an atheistic. The materials used are autobiographical accounts obtained from two books. One that has been used as a primary source and one as a secondary. By using Rambo?s process oriented theory of religious conversion relevant themes and categories were chosen and later subjected to further analysis using Pargament?s theory of religion and coping.

Tolerans eller normkritik? : och en analys av användning av lärarhandledningen Någonstans går gränsen

This study deals with how the Swedish school system handles questions concerning sexuality and normality. It is also an analysis of how the guidance material Någonstans går gränsen from RFSL Stockholm is used and could be used in teaching.The study consists of two parts. The first part is a study of literature that portrays how teaching concerning these issues is performed in schools, what methods that are recommended and what methods are actually used in teaching. The second part consists of interviews with people dealing with these issues in school and in organizations.My results show that schools often use a ?pedagogy of tolerance? while the guidance material and the research and theories concerning sexuality and normality advocate a more ?queer pedagogy?.

Bortom ?könet?? : om Simones förvandling, avslöjande och återställande i Ulf Starks Dårfinkar & dönickar (1984)

The aim of this paper is to analyse how subject, gender and sexuality is constructed in the book Dårfinkar & dönickar (1984), by Ulf Stark. In relation to this I have also analysed how the main character, Simone, develops from being a child into becoming a teenager.Queertheory is the theoretical basis of this paper. Queer theory questions heteronormativity and aims to dissolve conceptions and notions that function in an excluding and limiting way. Queer theory also questions conceptions that seem obvious and/or natural, for example ?woman?/?man? and ?homo-/heterosexuality?.I have chosen to focus the analysis on a number key events in the book and they are categorised according to Tiina Rosenberg`s three dramaturgic concepts: transformation, unveiling and restoration.

En granskning av det internationellt använda frågeformuläret International Outcome Inventory for Hearing Aids (IOI-HA).

Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.

OS i Kina, oberoende idrott eller politisk propaganda? : A Study of the Chinese Regime?s Political involvement, in the Beijing 2008 Olympic Games

The aim of this paper is to describe which view the Chinese government in connection with the Olympics wants to display for the natural world and analyze if this view coincide with China?s foreign-policy goals. A qualitative content analysis is used. By using the theory of rational choice and a model with three different political approaches I want to examine whether or not the foreign-policy goals of the Chinese regime comport with the view that displays in two major newspapers in China. Since the runoff voting in Moscow in 2001 for the 2008 Olympics the Chinese government has been able to act rational and to compose different strategies to use the Games in Beijing for political propaganda.

E-böcker och bibliotek. En diskussion kring den digitala beståndsutvecklingens möte med en gryende e-boksmarknad

In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.
