Baled silage has become one of the most important conservation methods in Sweden. Because we take our grass as silage we get the quality and the good hygenic that we would like to have. Silage has become a big buisiness also in the horse feeding where many of the breeders have changed from the hay to the hay-silage. The difference between regular silage and haysilage is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands on machinery and wrapping material since the grass gets sharper and harder to press together real hard. The main reason for the test was to compare two different systems for wrapping, the new Cross Pac and conventional.

Medborgarnas Förtroende för EU : En fråga om gemensam europeisk identitet?

Den Europeiska Unionen är en mångfacetterad samling länder med ett brett spektra av historisk bakgrund, geografisk placering och ekonomiska förhållanden. I denna uppsats undersöks huruvida en gemensam europeisk identitet kan bidra till en ökad tillit från medborgarna i unionen till EU som institution.Uppsatsens teoretiska underlag består av tidigare forskning. Denna forskning skapar ett fundament för den statistiska modell som används för att besvara frågeställningen.Med hjälp av data samlad ur bland annat Eurobarometerrapporter tar uppsatsen, via multipel linjär regression, fram en modell som förklarar förhållandet mellan den beroende variabeln ?förtroende för EU? och de oberoende variablerna ?uppfattning av gemensam europeisk identitet?, ?avstånd till Bryssel?, ?BNP per capita? och ?antal år som medlem i EU?.Resultatet visar en koppling mellan en högre grad av upplevd gemensam identitet hos medborgarna i ett land och ett ökat förtroende för EU.Vidare visar modellen ett negativt samband mellan förtroendet för EU och ett stigande värde på var och en av de övriga förklaringsvariablerna. Med andra ord: ju längre avstånd till Bryssel, ju högre BNP per capita och ju längre medlemskap i unionen desto lägre förtroende känner den genomsnittlige medborgaren för EU..

Högskolebibliotekens synlighet i lärosätenas strategidokument: En innehållsanalys av högskolornas strategiska dokument och bibliotekens strategiska planer

The aim of this master's thesis is to describe the visibility of the university libraries in the strategic documents from the actual universities to which they belong. And also, the image of themselves they send out, are examined. By examining different kinds of descriptions we want to get a clearer picture of how and in what amount the libraries are mentioned in highest level strategies. By doing this we expect to find out the libraries' strategic role in higher education and research. The research questions are: What role and function are assigned to the university libraries in strategies created by the schools' highest administrative levels? How do the libraries present themselves in their own strategies? The approach is cross sectional and the time frame is year 2008.
