Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

Health and convenience trends dominate the food industry and retailing business of today. The health consciousness is spreading while appealing product attributes concerning taste and packaging also are increasingly important. At the same time, the competition is growing fierce in the Swedish market with hard discount formats and niche concepts who also are trying to provide the market with perishables. Therefore, the pressure to lower prices is increasing making economies of scale and rationalization progressively more important. In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently, many stores went from in-store cutting-up and packaging to selling centrally packaged and distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere packages and needs to increase the knowledge about the market and the consumer.

Bakgrund: HIV är ett retrovirus som lagras i kroppens arvsmassa. Utan behandling angriper HIV-viruset kroppens vita blodkroppar och detta resulterar i att immunförsvaret kollapsar. Slutstadiet för sjukdomen är när den smittade har ett så dåligt fungerande immunförsvar att det inte kan skydda kroppen längre, vanliga infektioner blir mycket allvarliga. Slutstadiet kallas AIDS. Syfte: Syftet med denna litteraturstudie är att studera de specifika läkemedlen och hur behandlingen av HIV-1 smittade i Sverige har förändrats från 1980-talet jämfört med idag, 2009.

Bakgrund: Inom förskolan finns det många aktivitetersom utsätter både barnoch personal för risken att bli drabbad av smittsam sjukdom. Detta påverkar inte bara deras hälsa utan även spridningen av infektioner i samhället. Barn i förskola löper två till tre gånger högre risk för att få infektioner än barn som inte vistas på förskola. Tidigare studier visart.ex. att enkla förändringar på förskolan som skrivna riktlinjer för hygienrutiner, följsamhet till hand-och blöjbyteshygien och utbildning av personal och föräldrarkan minska sjukfrånvaron och risken förspridning av smitta.Syfte: 1) Att kartlägga grundläggande kunskaper hos förskolans personal,om hur sjukdomar sprids och hur man kan minska smittspridning.

Sub Saharan Africa has during the last decade become the world?s fastest urbanizing region. This change is concentrated to a few metropolitan areas one of them being Dar es Salaam, the largest city of Tanzania. Since the 1960s Dar es Salaam has grown from being a relatively small coastal city of approximately 300 000 people to become a bustling urban centre of four million inhabitants. This development has had a major impact on the city structure, which in turn has affected people?s welfare and the surrounding environment. One such consequence is the detrimental loss of urban vegetation and open areas in the city.

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Since long, Sweden has had exceptionally low calf mortality compared to most other countries. The tradition has been to keep calves in individual pens. With increasing number of cows per herd there is now a larger interest in more efficient and economical group systems for housing calves. However it has been noticed that bigger herds have more health problems and higher calf mortality than smaller herds. The early signs of disease are harder to detect when the animals are not fed manually.

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society. We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen. Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress? The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.

Subklinisk mastit (juverinflammation utan synliga symtom) är vanligt hos flera mjölkproducerande arter inklusive får. I kött- och pälsfårbesättningar kan subklinisk mastit ge lägre slaktvikt hos lammen till följd av minskad mjölkproduktion hos tackan. Risken att lammen försöker dia en annan tacka ökar om de inte blir mätta av sin mammas mjölk. Eftersom de flesta mastiter är bakteriellt orsakade kan lammens tjuvdiande vara en potentiell smittväg för juverinfektioner. För att förhindra smittspridning behövs snabba och pålitliga fältmetoder för att detektera juverinfektion. Syftet med studien var att kartlägga förekomsten av juverinfektioner hos tackor med kliniskt friska juver i svenska kött- och pälsfårbesättningar.

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

Mastitis, inflammation in the udder tissue, caused by S. aureus is a big problem in dairy cattle production. It causes suffering for the cow and curing or replacing the infected cow is costly for the farmer. It is known that beef cattle also suffer from mastitis caused by S. aureus.

There has always been global warming on earth and it is because of it that the earth is inhabitable. Without global warming the temperature on earth would be around -18 ° C instead of today's + 15 ° C. Global warming is generated by greenhouse gases like carbon dioxide and methane which trap long wave radiation in the earth's atmosphere. The problem today is that the global concentration of green house gases has significantly increased since the 1750's as a result of human activity. Today's values widely exceed the preindustrial values.

Bakgrund:En Central venös kateter (CVK) är en plastkateter som mynnar i ett centralt kärl nära hjärtat och används bland annat för administrering av läkemedel och blodprodukter. Användandet av CVK ökar inom sjukvården och kan förutom på intensivvårdsavdelningarna även ses i hemsjukvården och i den övriga slutenvården. Av alla patienter som får en CVK drabbas tre till sju procent av en infektion i blodbanan och varje infektionstillfälle innebär ett ökat lidande och en förlängd sjukhusvistelse. Dessa infektioner kan förhindras genom att hälso- och sjukvårdspersonal följer evidensbaserade riktlinjer och åtgärder.Syfte: Att beskriva hur sjuksköterskan kan arbeta preventivt för att förhindra uppkomsten av infektioner i blodbanan hos patienter med central venös kateter.Metod: Studien som genomfördes var en systematisk forskningsöversikt. För att finna relevanta artiklar skapades inklusionskriterier och söktermer.
