The bacterium Lactobacillus reuteri, which natural habitat is in the intestine of mammals and birds, uses glycerol as a substrate for production of the antimicrobial compound reuterin. Glycerol has been shown to decrease the number of Escherichia coli in human feces and it is believed to be due to in situ production of reuterin. E. coli belongs to the large family of Enterobacteriaceae, naturally occurring in the intestine, and pathogenic strains of E. coli have been shown to be one of several bacteria causing diarrhoea in calves.

The farming system is the basis of human existence through its production of provisions for man. By a continuous exchange of information, energy and material, between the ecosystems and the social systems, the farming system becomes an emergent property. The system's own properties, in the sense of farming methods, circulations and institutions, evolve through an adaptive process. Understanding this process and constantly learn from it, is the starting point for creating a sustainable development within farming systems. Thus, future farming system has to develop strategies that produce food provisions while at the same time takes into consideration the ecosystem's resilience and its integrity, but which also enables an ethical discussion. The institutions within the farming system are understood as links between the ecosystems and the social systems.

Since the beginning of the 1900s Sweden has had laws and rules governing the ownership of agricultural and forest land. The foundations of the current Land Ownership Law, ?Jordförvärvslagen 1979:230(JFL)?, are from 1979. The most recent review and adaptation of the law occurred in 2005. Its main purpose is to prevent a passive ownership of land in Sweden and to ensure that the land is actively worked.

[ An abstract in English will follow]Denna uppsats handlar om på vilket sätt användarinvolvering påverkar acceptansen av ett affärssystem. I studien redogörs varför acceptansen påverkas av användarinvolveringen, samt hur påverkan sker och vad som leder till den.IT genomsyrar idag så gott som alla former av företagsamhet. Affärssystem stödjer affärsprocesser i flera branscher, från tillverkande företag till renodlade tjänsteföretag. Ett företag behöver exempelvis anpassa både sina affärsprocesser och det nya affärssystem för allt som sker inom företaget. På grund av komplexiteten som detta för med sig är implementeringen ofta ett stort steg för företaget och dess anställda.

I denna studie analyseras skriftspråksutvecklingen hos sex elever i riskzonen för läs- och skrivsvårigheter. Syftet med studien är att klarlägga vilken roll specialpedagogiska insatser spelar för elevers skrift-språkliga utveckling. Har innehållet i stödet någon betydelse för elevernas utveckling och vad händer när stödet uteblir? Studien fokuserar på tidig kontra sen identifiering av elevernas läs- och skrivsvårigheter samt påföljande insatser. I detta sammanhang analyseras också hur dessa insatser påverkar elevernas självförtroende och motivation för skolarbetet.
