Introduktion: Patientsäkerhet är en viktig fråga inom hälso- och sjukvården. Vårdskadorna kostar inte bara samhället stora summor varje år utan även de drabbade onödigt lidande. Sjuksköterskor är den yrkeskategori som står patienterna närmast och innehar kunskaper om faktorer som påverkar patientsäkerheten. Syfte: Att beskriva sjuksköterskors erfarenheter av vad som påverkar patientsäkerheten på slutenvårdsenheterna på en medicinklinik.Metod: Studien genomfördes i form av semistrukturerade intervjuer som analyserades genom kvalitativ innehållsanalys. Som teoretisk referensram har Jean Watsons omvårdnadsteori använts.

The study was performed in southwest of Colombia in close collaboration with the interna-tional centre of tropical agriculture, CIAT and supervised from the university of Valle, Uni-valle, Cali, Colombia and from the Department of Landscape Management and Horticultural Technology, SLU, Alnarp, Sweden. The main purpose of this thesis was to evaluate six different non-conventional insecticides and their ability to control whitefly Aleurotrachelus socialis in cassava Manihot esculenta. The aim was also to evaluate the most appropriate application technique for these products which were: Agronim, Biomel, Bioneem, EcoSwing, Coco soap + chilli and L´Ecomix. The products are mainly based on vegetable oil, soap and plant extract and cause primarily a physical contact effect which affirm that it is fundamental to obtain a high coverage of the underside of the leaves, where A. socialis is present.

The purpose with this study was to analyze the possibilities to produce organic lambs and to hihglight the most common difficulties in such a production system. A description of current organic and conventional lamb production systems was conducted, both from Sweden and from some other countries. The Department of Animal Environment and Health at SLU in Skara performed the project together with The County Board of Agriculture in Västra Götaland and Värmland and The Swedish Animal Health Service. The project lasted from 2002 to 2004. The student report contains the years 2002 and 2003. In the year of 2003 there were 210 000 adult sheep in Sweden, of which 16 400 adult sheep were certified by KRAV. Of the different countries in Sweden, Västra Götaland and Gotland had the largest number of sheep, 14 and 13 per cent of the total number.
