Refugia som metod för att minska utvecklingen av anthelmintikaresistens hos får

Anthelmintic resistance is a major problem in sheep husbandry all over the world. One way toslow down the development of anthelmintic resistance is to keep part of the parasitepopulation in refugia (unexposed to drugs) which will maintain the genes for susceptibilitywithin the population. Climate, type of parasite and drenching regimes effect the size of therefugia. Dilution of resistant with susceptible parasites, targeted treatment and targetedselective treatment are all management strategies that employ refugia. Dilution is possible butcomplicated.

Faktorer som påverkar sjuksköterskans omvårdnad av mrsa bärande patienter

Mulitresistent staphylococcus aureus (MRSA) is a bacteria that is resistent against penicillin, this makes it difficulte to treat. MRSA causes woundinfections and other seriouse conditions. If MRSA establishes in an hospital environment it often spreads fast. Common ways of spreading MRSA is through direct or indirect contact. The nurse should work according to guidelines, apply hygienic routines and prevent the spread of infections.

Riskfaktorer för Staphylococcus aureus i mjölk och på has hos mjölkkor :

Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.

Pre-treatment of grain for ethanol production during storage

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

Tala är silver, skriva är guld (?) En studie om bloggars demokratiska potential

The number of blogs, from weblogs, are increasing every day. Blogs are also becoming more visible in the public debate as well as the awareness of their existance is rising among politicians and citizens. The aim of this thesis is to answer the question what democratic potential blogs can have. This question will be answered by initially studying the research that exists today about weblogs and democracy. The second part of the analysis consists of a selection of texts from weblogs that touches this subject.

Kreditkort till en yngre målgrupp : Relationsuppehåll genom vilja eller hinder

This thesis concerns the Swedish credit card market to a younger public and specifically Nordea as a card editor. The purpose is to investigate whether a Swedish bank can, and want to build long term relationships with a young public through credit cards, and if so, how they do this.The theoretical background formulated by researchers Bendapundi and Berry consists of four key factors of relationship maintenance; trust, dependency, dedication and constraint. These key factors are also assembled in an analytical framework. The empirical findings mainly consist of interviews with three employees at Nordea. They describe a recent segmentation of the bank?s customers with the issuing of a new credit card; Mastercard Silver.

Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

IGF II : structure, function and role in disease

Den insulinlika tillväxtfaktorn II (IGF II) är ett proteinhormon som reglerar cellers proliferation, tillväxt, migration, differentiering och överlevnad. Den utövar sin biologiska funktion via IGF I-receptorn. Dess tillgänglighet för bindning till IGF-1R regleras av en familj bestående av sex IGF-bindarproteiner (IGFBPs). IGF II kan också inducera mitos via en alternativt splitsad variant av insulinreceptorn (insulin receptor isoform A (IR-A)). De cirkulerande nivåerna av IGF II kontrolleras genom IGF II-receptorn, som saknar signalfunktion och är homolog med mannos-6- fosfatreceptorn. Tystad prägling av IGF II-genen är en återkommande observation vid en utvecklingsrubbning kallad Beckwith-Wiedemanns syndrom, vilket innefattar okontrollerad tillväxt och i många fall en njurtumör hos barn, Wilms? tumör. Tillväxthämning ses vid mutationer i genlocuset hos IGF II och den närliggande genen H19 vid en annan utvecklingsrubbning, Silver-Russells syndrom.

Effekt av myrsyra och beta-laktamas på penicillin- och S. aureus-halt i mjölk till kalvar :

A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.

Lukt i sporttextil - nödvändigt ont eller möjligt att motverka?

Sporttextil som luktar illa är ett utbrett problem och något som de flesta motionärer är bekanta med. En enkätstudie som genomfördes visade att mer än hälften av respondenterna någon gång upplevt att deras träningskläder luktat illa även efter tvätt. Även om lukt i sig inte är något farligt eller skadligt kan det ändå leda till obehagskänslor hos individen och det finns därför ett önskemål om en lösning på problemet. Lukt i sporttextil kan delvis härledas till bakteriers metabolism av utsöndrad svett. Dessa doftämnen tros kunna ackumuleras i textilen vid tvätt och användning.

Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

Prognostisk betydelse av radiologiskt detekterad gasförekomst i tunntarmen hos katter utsatta för fysiskt trauma :

The aim of this study was to see if an increased amount of gas could be seen in the small bowel of cats subjected to trauma and if measuring the amount of gas could be of any use in the clinical evaluation of the patient. When the peristaltic waves in the small bowel decreases due to neurological damage or chock the microorganisms of the gut grow in number and possibly produce more gas and toxins. When the cat is stressed it can swallow more air then usual, and the air that is in solution with the chyme in the lumen of the gut separates from the ingesta. When the bowel isn?t moving it becomes easier for bacteria and toxins to penetrate the wall of the gut, and then get access to the bloodstream.

Mastcellens funktion vid försvar mot infektioner

The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

Mer för prakten än för nyttans skull. : Statusmarkeringar i bouppteckningar från Virestad socken 1750-1759

Most scientists believe that in the good times the peasant had the opportunity to follow fashion. Virestad parish does not follow fashion. My purpose is to try to understand something of the mechanism that made Virestad do so: that I will do by analyzing the results in relation to the concept of status. My main source is estate inventories. Here I examine the status markers and differences in what they invested in clothes and jewelry in relation to the estate's proceeds.The lower the balance, the more percentage they need to put on clothes.

Den dubbla yrkesrollen : Om yrkeslärares kompetensutveckling inom karaktärsämnet

The Sami people are a national minority in Sweden, but are also considered as native citizens of Sweden, Norway, Finland and Russia. The world has however a very limited knowledge about the Sami?s and their cultural background.The aim of this proposal is to examine six different history schoolbooks which depict the Sami people in Sweden. In addition, one of the key elements of this proposal is to understand how the selected literature represents the Sami people.Lastly, the proposal also seeks to review if the literature in the schoolbooks represents the elementary curriculum goals (Lpo94).The selected method was to do a text analysis of the literature and to illustrate that is presented in the reviewed schoolbooks. The text analysis is completed with an analysis of the illustrations and pictures that are presented in the selected schoolbooks.The key findings were that the review in majority of schoolbooks has stereotypical descriptions of the Sami people. The Sami people are generally depicted with the hut and the reindeer management in majority of the reviewed schoolbooks.The research about the Sami people is inappreciable in majority of the reviewed literature. In addition, the Sami people are often presented in connection with ?other? history, such as the silver ore in the mines or the territory dispute with settlers from the south of Sweden.
