The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

It is important to know what is normal in the wound healing process in order to determine what happens when a wound does not heal as expected. If the amount of bacteria in the wound gets too large the body will not be able to defend itself and it becomes an infection. Colonization and infection are common elements in wound management and it is often the veterinary nurse role to deal with wounds in a proper manner. Antibiotics are drugs that either kill or inhibit the multiplication of bacteria or fungi, and have been in veterinary medicine for approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

Den senaste FN-rapporten som utfo?rdes av IPCC sa?tter punkt pa? faktumet att katastrofala klimatfo?ra?ndringar kan undvikas utan ma?rkbar inverka pa? levnadsstandarden. Det go?r fo?rnybar energi till den billigaste och minst riskabla va?gen till en fossilfri framtid. Detta motiverar intresset fo?r att underso?ka lo?nsamheten i solcellsanla?ggningar fo?r elna?tinmatning.

Vid TCF-blekning av pappersmassa är väteperoxid en av huvudkemikalierna. I dagsläget är det svårt att styra blekstegen. Operatörerna måste ta hänsyn till produktionstakt, blekbarheten på massan varierar och fördröjning i trender. PO-bleksteget på Södra Cell Värö har en ungefärlig uppehållstid på 4 timmar och det är först efter så lång tid som man kan se hur en förändring verkligen slår igenom. Överblekning kostar väldigt mycket i kemikalieåtgång och det är därför efterfrågat ett sätt att kunna styra och optimera peroxidblekningssteget.

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

The aim of this paper was to explain protein degradation in silage and protein quality and biogenic amines in silage and their effects on the health of the dairy cows. After harvest-ing, the plant proteases degrade the proteins in the plant. The protein degrades to different fractions with different digestibilites in the rumen. Fraction A contains non- protein nitro-gen which is peptides, free amino acids and amines. True protein is in the fraction B and is further divided into three subfractions depending on their solubility.

The current debate about environment and climate change has contributed to more andmore investment in alternative energy sources such as wind, solar and biogas. The Swedish Parliament has set the target that wind power should supply 10 TWh in 2015.In Sweden, wind power establishment began in the early 1980s. Since then the development has gained a tremendous momentum. The purpose of this study was to find out what problems wind power brings and what power relations that exists in connection with wind power establishment and how the landscape is affected by windpower construction, focusing on some cases in Falkenberg and Varberg. This study shows that wind power establishment is a very complicated process.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

I en tid med allt mer påtagliga miljöhot, ökande CO2-utsläpp och stigande efterfrågan på el är det viktigt att utvecklingen av billig och effektiv förnyelsebar energi fortsätter runt om i världen för att kunna konkurrera mot billigare, icke förnyelsebara, energikällor. Ett steg i detta är att utveckla och effektivisera solkraft till den nivån att länder och företag väljer att investera i solkraft. Mer konkret kan det ske igenom utveckling av nya, mer effektiva, solcellsmoduler.I denna studie ska en ny typ av solcellsmodul, SmartPlus ? utvecklat av Innotech Solar, jämföras mot deras standardmodul EcoPlus för att undersöka om den nya modulen kan bidra till högre andel solkraftsgenererad el i Sverige och där med minska CO2-utsläppen. Den nya solcellsmodulen är framtagen för att bättre kunna hantera och ta tillvara på solinstrålningen om en del av modulen utsätts för skugga, därför kommer studien simulera de båda moduler i en solpark där det sker intern skuggning mellan modulraderna.

The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

Kroppens organ består av många miljoner celler, som har sin uppgift i det organ de befinner sig i. När en cell dör ersätts den med en ny som har samma uppgift. Cellerna samarbetar och kommunicerar via olika signaler, vilket är en förutsättning för att kroppen ska fungera. Cancercellerna delar på sig snabbt vilket leder till celltillväxt. cancer är den vanligaste dödsorsaken i Sverige, efter hjärt- och kärlsjukdomar.

The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF).
