Mantelplymer är ett mycket omdebatterat fenomen inom geologiämnet. Existerar de och var har de i så fall sitt ursprung? Detta kandidatarbete behandlar mantelplymens karaktäristika och de för- och motargu-ment för dess existens som finns i litteraturen. Hypotesen om mantelplymer uttrycktes första gången 1971 av Jason Morgan där det föreslogs att hett mantelmaterial förs från Jordens kärna till ytanMantle plumes are subject of a great discussion within the field of Geology. Do they really exist, and in that case, from where do they originate? The scope of this Bachelor thesis is to discuss the characteristics of mantle plumes and the arguments in favor of and against their proposed existence. The mantle plume hypothesis was first presented in 1971 by Jason Morgan, suggesting diapirs of hot r

Perfluoroktansulfonsyra, PFOS en av människan tillverkad organisk syra, vars väteatomer har blivit utbytta mot fluoratomer och är en nyligen upptäckt förorening som tros finnas i 3,6 miljoner svenskars dricksvatten. Den här kandidatuppsatsen är en litteraturstudie i vilken förekomsten av PFOS i grundvattnet studeras. Det är förmågan att bilda ytbeläggningar som är avvisande mot smuts, fett och vatThe manufacture of products containing PFOS started in the 1950s, and has mainly been used as fire-fighting foam, (Aqueous Film Forming Foam), flooring, textiles, leather impregnation, cleaning and in impregnated paper. This has resulted in a global contamination that is widely spread in the hydrosphere, biosphere and the atmosphere; due to long and intensive use without any regulations. PFOS is a

Epilepsy is one of the most common neurological disorders. The most common way to treat epilepsy is by taking antiepileptic drugs, however, still a considerable portion of patients are still suffering from intractable epilepsy so new treatment methods are needed.

Skogsbruket är viktigt för svenskt näringsliv och står för ungefär 20 % av Sveriges totala export. Efterfrågan på virke blir därmed stor vilket resulterar i att avverkning sker ständigt, året om, på all typ av mark under alla olika sorters väderförhållanden. Ett stort problem inom skogsbruket är de markskador som ofta uppstår efter en slutförd avverkning. Markskador ändrar markens textur och egensForestry is important for Swedish industry and accounts for 20% of Sweden’s total export. The endless demand of wood results in logging all year round, but other aspects have to be taken into consideration. The ecology, forest recreation and the outdoor activities that the forest is providing is very important to preserve. A major problem in forestry is the soil damage after a successful harvest.

This thesis analyses the impact of several natural resources on economic growth in the empirically rather poor Sub-Saharan Africa during the time period of 1990-2010. By performing panel regression analyses based on economic and political data from the countries in Sub-Saharan Africa, the conclusion that the production of diamonds promotes economic growth the most could be made. As an example, the

Utrymmet på jordytan håller på att ta slut, vi blir fler och fler och våra städer blir större och större. Istället för att expandera våra städer utåt borde det fokuseras på att göra mer plats i städerna. I en vanlig svensk stad utgörs idag nästan 50 % av vägar och annan transport. Om det mesta av all transport hade kunnat förflyttas ned under marken istället, hade den frigjorda platsen kunnat bli The room for the human race on earth is dwindling. The population is increasing and our cities are expanding every day. Instead of expanding our cities we could focus on creating more room inside our cities. Today close to 50% of the total area of a normal Swedish city consist of transport infrastructure What if we could move most of that 50% down below ground? Imagine all the space it would creat

The prevalence of allergic disease is continuing to increase worldwide, and it has even become a major concern in public health. Allergic reactions are developed to otherwise harmless substances and may be both life-threatening as well as discomforting for patients in their daily life. Therefore, a more detailed knowledge about how antibodies interact with allergens and effector cells in allergic

The purpose of our study is to determine the importance of oil exports in relation to GDP in countries located in Sub-Saharan Africa when it comes to promoting economic growth. Due to the fact that oil accounts for approximately 40 percent of the world’s total energy production, and is predicted to do so for at least 45 more years to come, we found this a highly relevant topic to look into. At th

The encoding-retrieval match has been established as a means to improve memory performance. It has recently been proposed that memory performance is not only explained by the encoding-retrieval match and that the cue overload effect needs to be taken into account when predicting memory performance. In the present study, participants were tested using a cued recall methodology. During a study phase
