Mögel på Textil -vid import av textila varor

Under lagring och transport av textila varor från Asien kan risken för mögelangrepp vara stor, något som sedan vid uppackning kan vara skadligt för hälsan. Situationen så som det ser ut idag kan medföra stora problem och kostnader hos textilföretag och att hitta möjliga åtgärder för att förebygga skador är därför av stort intresse. För att kartlägga problemen med mögelangrepp på textila material har både informationssökning och praktiskt arbete genomförts. Mögeltillväxt sker då det är gynnsamma betingelser med hänsyn till klimat, näring och syretillgång. För att mögeltillväxt inte ska angripa textila varor finns en rad förebyggande åtgärder som kan vidtas, åtgärder som alla handlar om att göra förutsättningarna på ett eller annat sätt ogynnsamma.

Comparison of real-time PCR assays for screening of meticillin-resistant Staphylococcus aureus

Staphylococcus aureus belongs to the normal flora. Many healthy people are colonized by the bacterium mainly in the nose but also on the skin and on other mucous membranes without showing symptoms. After damage to the skin, the bacterium can enter the wound and cause infections. Methicillin-resistant S. aureus (MRSA) is resistant to b-lactam antibiotics such as penicillin and methicillin.

Biogaspotential hos våtmarksgräs

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

Snus och dosor - Förpackningsdesign, märke och identitet

The purpose of this essay was to examine the packaging design´s communications related to the colloquially brand's symbolic capital and how they became meaningful through experience and perceptions that led to the identification processes in the consumer society. There were eight interviews of snuff users who became my main collections materials. My theoretical framework was discourse psychology´s emphasis on language and Bourdieu´s concept provided important tools in the analysis of the material.I could highlight that packaging design and the brand had influenced the informants and given them symbolic beliefs and what it meant to sniff a certain brand. Color, brand awareness and price were crucial in choosing where the informants attributed themselves the cans symbolic values to their identity. It could be inferred high and low status perceptions based on stereotypes in the design itself..

IT och flerspråkighet i gymnasieskolan

The purpose of the study is to examine the multilingual student?s use of IT in school.The study also highlights the teacher?s view of development and how they use IT in their own teaching.A qualitative approach study was conducted to acquire a deeper understanding of students' language learning by using IT. In the study, it was assumed socio-cultural perspective in which learning takes place through interaction with others.The result shows that multilingual students have difficulty understanding information available on the internet and they are either waiting to meet a teacher to get a clearer picture of what to do or doing tasks even though in some cases misunderstand the task. Language teachers also confirm student?s impression and at the same time express the concern that students are reading less.This study shows that there may be correlation between students' learning motivation and an understanding of instructions online.

Evaluation of ELISA and rapid test for the analysis of fecal Calprotectin

ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.

Kapacitetsberäkningsmodell för materialhanteringsflödet på Ericsson i Kumla

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

Itrakonazol till häst : en farmakokinetisk möjlighet?

Itraconazole is a third generation azol, a fungicide which acts by inhibiting ergerosterol synthesis in the fungal cell membrane, and thereby disturbing fungal regeneration. It has proven to be less toxic, to have a broader spectrum of activity and to be more potent than its predecessor ketoconazole. Itraconazole is only available in therapheutics approved for human use. Pharmacokinetic studies has been performed in humans, dogs, cats and laboratory animals. Although itraconazole has been used tentatively with good effect against fungal infections in horses, no pharmacokinetic studies have yet been done.
