This paper deals with prehistoric charred organic material, interpreted as bread, found in graves and in the underlying settlement at Kalvshälla, Järfälla parish in Uppland. The aim was to categorize the organic material morphologically and with the help of Fourier transformed Infrared spectroscopy (FT-IR) to see whether it was bread or not. Material from 13 graves (dated to Late Roman Iron Age until Viking Age) and 3 finds from the settlement have been analysed. Differences were noted both in shape, porosity and structure. Some of the material has been interpreted as cereal based foodstuff instead of bread due to morphological discrepancies.

Mobile Arts have a technical platform for handling maps and community-featured Points of Interest in cellular phones, where the users themselves can share locations with other users either in groups or public. Development of the platform regarding network communication has been included in this paper. The work evaluates different feasible business models regarding packaging the platform as a commercial application and also faces issues users have when using the product. Even if users found maps and POI interesting and cool in cellulars, the technical difficulties and lack of product focus during beta testing, were present. Therefore, the writers recommendation is more development of the platform and using a business model where Mobile Arts deliver to existing communities.

Under 2005 och 2008 inventerades förekomsten av större vattensalamander(Triturus cristatus) i Gävleborgs län. Ett till synes isolerat fynd gjordes väster om Hofors. Inventeringarna utfördes med flaskfällor och visuell observation och lokaler valdes via kartblad enligt kriterier på vattenytans areal, rörelse och distans till väg. Syftet med detta arbete var att undersöka huruvida den observerade isoleringen var faktisk eller endast ett resultat av den använda inventeringsmetodiken. Detta arbete baserades på en radie kring en känd population där radien baserades på spridningsdistans, mognadsålder samt tid sedan den förra studien. Lokaler valdes sedan ut inom radien med krav på areal vattenyta och förekomsten av stillastående vatten varpå inventeringar utfördes med flaskfällor.

En av de allra centralaste aspekterna vid investerings- och finansieringsbeslut handlar om den risk som en investering innebär och den avkastning som marknaden kräver. Som kapitalplacerare vill man veta risken i en potentiell investering för att kunna beräkna det avkastningskrav man måste erhålla, och om investeringen motsvarar ens egen riskexponering. Investeringsbeslut på olika marknader innebär att olika typer av risker tas i beaktande och resulterar därigenom i att avkastningskraven skiljer sig åt mellan marknaderna. Området för den här undersökningen ligger i risker och avkastning på Private Equity marknaden där skillnader existerar jämfört med investeringar i börsbolag. Förespråkare för Private Equity industrin menar att Private Equity innebär möjligheter till betydligt högre avkastning än investeringar som görs i noterade instrument och då främst i jämförelse med aktier.

Att "smarta" brädspelande datorprogram har blivit mycket bättre under de senaste årtiondena har väl knappast kunnat undgå någon. Med brädspel menar jag spel såsom Go, Othello, Backgammon och Schack. Idag spelar program, som körs på en reguljär PC, bättre än de flesta människor. Vad är det som gör dessa program så bra? Hur kan man lära en dator att spela ett så pass komplext spel som Othello på en sådan nivå att ingen människa har en chans att vinna? I detta examensarbete kommer jag att försöka förklara mekanismerna bakom ett toppspelande Othelloprogram.

The traditional Swedish way of dealing with browsing damages made by moose, is to reduce the moose population. However, a growing way of dealing with damages made by several ungulate species, including wild boars in particular is to redistribute them with supplementary food sources. Attracting them to settle in habitats less vulnerable to damages made during foraging. This study we tracked collared moose in southern Sweden from January throughout April in the year of 2009. From the tracking data their ?favourite? positions was selected and visited in order to study the features that attracts moose during winter.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

På Island finns många gamla traditioner. Jordbrukare har under lång tid använt sig av allmänningar för att låta djur beta på under sommarmånaderna. Allmänningarna spelar också en stor roll för det isländska kulturarvet. Den viktigaste händelsen i samband med allmänningen är den årliga fårskiljningen. Fårskiljningen äger rum på hösten och då är nästan varenda person i bygden inblandad på ett eller annat sätt. Man delas upp i olika arbetslag för att hämta hem fåren från allmänningarna som är belägna i fjällen. I denna uppsats skriver jag om min hembygd på norra Island, närmare bestämt Deildardal i Skagafjördurs kommun.

Field Horsetail Equisetum arvense L. Colt's-foot Tussilago farfara L. Stationary perennials: Dock Rumex L. Mugwort Artemisia vulgaris L. Dandelion Taraxacum F.

The effects of dexmedetomidine and butorphanol sedation on skin reactivity during intradermal testing in healthy dogs were evaluated. The effects of dexmedetomidine and butorphanol were compared to medetomidine, a sedative agent having scientific proof of not interfering with skin test reactivity, in a randomised, double blind, cross over study performed on 8 adult dogs. The dogs were sedated with medetomidine (Domitor vet.®, 0,01 ml kg-1) intravenously, or dexmedetomidine and butorphanol intramuscularly (Dexdomitor vet.®, 0,01 ml kg-1; Dolorex vet., 0,01 ml kg-1) after which they received intradermal injections of positive control solutions (histamine 0,1 mg ml-1, 0,05 mg ml-1, 0,025 mg ml-1), a negative control solution (0,9 % NaCl) and allergen extract (Dermatophagoides farinae, Cladosporium and Artemisia vulgaris). After a wash out period the trial was repeated with a reversed sedation protocol.Skin reactivity (wheal size, induration and erythema) and quality of sedation (immobilization, response to stimuli and injections as well as over all working conditions) were evaluated. The combination of dexmedetomidine and butorphanol provided reliable, good sedation and analgesia without adverse effects.

This paper is about the new programming language from Microsoft, C# (See Sharp) and the .NET Framework. They are still in beta-version, but will be released on the market in February 2002. This paper presents C#, not in detail but the characteristics that distinguish the language. A comparison is done with C++ and Java, since C# is most resembling to these languages. Both C# and Java have been developed from the mother- language C++.

Uppsatsen behandlar olika aspekter inom integrationsprocessen vid företagsförvärv. Företagsförvärv är synnerligen vanligt förekommande i Sverige idag och inte minst i IT-branschen. Genom denna fallstudie av två förvärv inom IT-branschen ges en överblick över vilka fallgropar och problem som kan finnas med de mjuka aspekterna i en integrationsprocess. Denna magisteruppsats är en kvalitativ studie av integrationsprocessen inom områdena Organisationsstruktur, styrning och ledarskap, Kommunikation, Kulturskillnader samt Kompetensförsörjning. Undersökningen har genomförts genom intervjuer och enkäter vid två IT-företag, Alfa och Beta (dessa företag samt respondenterna är anonyma).
