Evaluation of tools for analysis and quantification of Fusarium mycotoxins
Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Prevalence of toxin-producing strains and antimicrobial resistance in isolates of Staphylococcus hyicus from pigs with exudative epidermitis and from healthy pigs
Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

Clostridium difficile toxins in meat-producing guinea pigs in the highlands of Peru
The guinea pig is an important meat-producing animal in Peru as well as in several other South American countries. They are held in different kinds of systems, from the small backyard breeders with few animals to the large commercial farms with thousands of guinea pigs. One of the major issues at the farms is animals dying of unknown causes. Salmonellosis is often considered as a major cause, but samples for confirmation are rarely taken. It has been known for a long time that Clostridium difficile (C.
Arbetsterapeutiska interventioner till barn med cerebral pares i samband med Botulinum toxin A
Syftet med studien var att beskriva arbetsterapeutiska interventioner till barn med cerebral pares i samband med Botulinum toxin A (BTX-A). Urvalet bestod av åtta arbetsterapeuter som arbetade på olika barnhabiliteringskliniker i Sverige. Arbetsterapeuterna intervjuades utifrån en intervjuguide innehållande bakgrundsinformation samt öppna frågeställningar. Det insamlade datamaterialet analyserades med en kvalitativ innehållsanalys. Resultatet presenterades med hjälp av tre teman som beskrev de arbetsterapeutiska interventionerna.
Metabolism av mykotoxiner i våmmen
SammanfattningMykotoxiner är sekundära metaboliter som kan bildas av vissa mögelsvampar. Idisslare har generellt ett högre skydd mot mykotoxiner än vad enkelmagade djur har då våmmens mikroorganismer kan fungera som ett extra skydd mot mykotoxikos. Trichotecenerna deoxynivalenol och T-2 toxin bryts ner till de-epoxymetaboliter i våmmen genom att dess toxiska epoxyring spjälkas bort. Deoxynivalenol metaboliseras helt eller delvis av våmmens mikroorganismer, medan T-2 toxinets nedbrytningskapacitet inte är lika hög. Aflatoxin B1 har en låg nedbrytbarhet, och inga metaboliter har kunnat detekteras i våmmen.
Revision av miljöledningssystemen i statliga myndigheter : Utvärdering av ett verktyg i det systematiska miljöarbetet
The Swedish government decided in 1996 that the governmental authorities are to implemementenvironmental management systems. Each year, the Swedish Environmental ProtectionAgency compiles the authorities? reports on their environmental management systems. Thecompilation shows that not more than 20 % of the authorities perform environmental audits.This study aims to investigate the authorities? view of internal environmental audits, the incentivesof performing them.
Case Pöyry Sweden AB : Miljöprestandaindikatorer för ett tjänsteföretag
The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.
Varför miljöredovisning? : en undersökning av lastbilstransportbolag
Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.
Miljöutredning för Bräcke Diakoni
The environmental work in Sweden has developed a lot over the past fifty years. Today, most companies have some kind of environmental work. Environmental activities are regulated by the Environmental Code, which applies in parallel with other laws. This report is an environmental review for Bräcke Diakoni. The report aims to find out how much environmental impact Bräcke Diakoni has.
Ansvarsutkrävande i global miljöstyrning -Möjlighet eller utopi?
Is accountability possible in global environmental governance? The purpose ofthis thesis is to examine if accountability is possible in global environmental governance. From an accountability perspective the thesis tries to illuminate global environmental governance. An investigation about the conceptaccountability is made and the thesis also illuminates the possible problems that exist in global environmental governance which exist of such a large amounts of different and often private actors. By investigating and examine the concept of accountability from different aspects and by using Global Compact as a example of global environmental governance the thesis try to answer if accountability actually exist in global environmental governance and in what way it is possible to demand accountability.
