Plasmacytos är en kronisk, persistent och progressiv viros med hög dödlighet och allvarliga reproduktionsproblem som ofta kallas Aleutian disease (AD). Sjukdomen drabbar i huvudsak mink och är ett stort problem på minkfarmer, men kan även drabba vilda mård- och hunddjur. Undersökningar för att kartlägga utbredningen av plasmacytos i den vilda minkpopulationen har inte tidigare gjorts i Sverige. Nittio minkar från hela Sverige obducerades och provtogs avseende antikroppar mot ADV (Aleutian disease virus) och av dessa var 41 stycken (46%) seropositiva, vilket är en hög siffra jämfört med våra grannländer. Infektionen visade sig vara spridd över hela Sverige, men det förelåg en tydlig säsongsvariation där en högre andel seropositiva minkar påträffades på våren.

In 1989 the Cold War ended and in 1991 the Soviet Union ceased to exist, over night the ruling paradigm of International Relations was obsolete. What would happen now? Samuel Huntingtons answer was that in the future, cultural identity would be the most important factor behind international conflict. And that the threat of world war would come from clashes between civilizations instead of clashes between ideologies like during the cold war. Was he correct? This thesis is an attempt to find out if Huntingtons theory was right in its predictions of the world to come.

In the Darfur region, located in the West of Sudan, there is a conflict between rebel groups and the government-supported Janjaweed militia. The fighting?s, which started in 2003, has caused the loss of at least 200 000 human life and more than 2 million people have fled their homes. The conflict has been described as a? prolonged Rwanda?.

The aim of the study has been to examine how young men from Stockholm construct "Masculinity". This has been done by examining what men think is an ?ideal man?, what "makes a man a man", which expectations they meet as men and how the life of a man differs from the life of a woman. This has been examined through three semi-structured group interviews with the total of ten men. The results have been analysed with Raewyn Connells Theory of Masculinities, the idea of ?Doing Gender? by Candace West and Don.

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

Den största akuta risken inom dricksvattenförsörjningen är vattenburen smittspridning. Dricksvattenrelaterad smittspridning förekommer i störst utsträckning i utvecklingsländer med dåliga sanitära förhållanden. Under 2000-talet har de nordiska länderna drabbats av flertalet dricksvattenburna sjukdomsutbrott vilket har lett till att mikrobiella föroreningar uppmärksammats som ett problem även i Norden. För att säkerställa att det dricksvatten som distribueras är av god mikrobiologisk kvalitet krävs att säkerhetsbarriärerna i vattenverket är tillräckligt effektiva för alla typer av mikrobiella föroreningar. Vissa mikroorganismer har uppmärksammats som mer tåliga mot olika desinfektionsmetoder, till exempel klorering, än vad som tidigare varit känt.

Modern methods for managing pine (Pinus sylvestris) create homogenized forests. This decreases nature?s potential for biodiversity and might threaten species in need of different types of milieu. The main purpose of this study was to investigate how important older pine trees are for biodiversity. In the Hall-Hangvar Reserve in the north-west part of Gotland, insects collected from traps showed that more species were found in old or dead trees compared to younger pine trees.

Det här arbetet handlar om tambins inverkan på naturligt förekommande pollinatörer. Min frågeställning berör: tillgången på näring, hälsotillståndet och populationsnivån hos naturligt förekommande pollinatörer i förhållande till tambins närvaro. Det som framkommit av den här litteraturstudien är att introducerade tambin leder till att naturligt förekommande pollinatörer minskar i antal kring bikuporna, en del arter söker föda på andra blommor eller senare på dygnet än tidigare. Den minskade tillgången på föda som denna konkurrens innebär har en negativ inverkan på humlors kroppsstorlek och därmed deras överlevnad. Samt att tambin kan föra över patogener så som varroakvalster, nosemasjuka och deformed wing virus till humlor vilket leder till minskad livslängd och sämre fortplantning..

I denna studie har vi undersökt unga kvinnors identitetsskapande i en mansdominerad snowboardkontext, samt deras copingstrategier. Sex semistrukturerade intervjuer analyserades med en deduktiv tematisk ansats. Analysens koder och teman grundas i första hand på göra-kön modellen (West & Zimmerman, 1987), tidigare studier som identifierat en maskulinitetsnorm inom snowboardvärlden samt tidigare beskrivna copingstrategier som kvinnor i minoritet använt sig av. Resultatet delades in i fyra teman: Den typiska snowboardåkaren, Sammanhållning och särhållning, Tjejer i backen samt Copingstrategier. Vår tolkning är att informanterna talade om sig själva som fysiskt och psykiskt avvikande från maskulinitetsnormen.

Japansk encefalit (JE) orsakas av Japansk encefalit virus och är en allvarlig myggburen sjukdom med upp till 50 000 humanfall per år. Kliniskt utvecklad sjukdom har en letalitet på runt 25 % och många som överlever drabbas av svåra neurologiska skador. Sjukdomen har en stor geografisk utbredning i Asien och sjukdomsfall ses främst på landsbygden. Viruset vidmakthålls i en zoonotisk cykel mellan mygg (främst Culex tritaeniorhynchus), vadande fåglar och tamsvin. Människor är accidentella värdar.

The purpose of this paper has been to explore how Internet is perceived, with reference to youth, risk and responsibility, by a section of the population in North-West Skåne in Sweden. The questions central to our area of interest were:- Where does the responsibility for a safe Internet environment lie?- What measures are believed to be able to make Internet safer?- Are the opinions about safety on the Internet affected by an individual'sknowledge and experience of the Internet?- Is there an awareness of which institutions are involved in Internet safety?We compared the results of our survey with earlier surveys done by SAFT and Eurobarometern. Additionally we compared various categories such as gender and age to discover any patterns within the groups.There is a clear conflict in the answers given by the group we studied, between the desire to have access to all the information and experiences Internet has to offer and the desire to protect youth from inappropriate content and/or influences from unknown sources. While we did find concern regarding issues of safety we did not find any indication of "moral panic"..

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.

The aim of this thesis is to describe and analyse the development of libraries on Tjörn, an island on the Swedish west coast. I have divided the thesis in two parts, one in which I will describe the libraries development between the years 1873 to 1952 in the municipality of Stenkyrka and one in which I will describe the libraries development between the years 1976 and 1985 in the municipality of Tjörn. The study is mainly based on written materials and a theoretic model will also be used in which I apply three factors, society, the libraries economy and individual actors on the library activity. The libraries in Stenkyrka during the early period were dependent of public grant from the state for their survival and the libraries were undeveloped. The society around them was poor and hardly any money or assistants came from the municipality.
