Som minst är alltid 5% av jordens yta täckt av havsis. Det gör att isen har en avgörande roll i klimatet, särskilt vid polerna, då den påverkar utbytet av värme, massa och rörelse mellan havet och atmosfären. Ett snötäcke ovanpå isen förstärker ytterligare effekterna av isolering och reflektion. Havsisen och snön är av stor betydelse för det globala klimatsystemet. Dock är det svårt att inhämta dThe sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. Sea ice and snow is of significant

This essay should be regarded as an artifact study and as a foundation for continued research. As very little has been written about younger blackware, the focal point of this study is on key problems such as dating, function and production. The material of the study is from the excavation of Kv. Apotekaren 4, carried out 1979-1980. The stratigraphy of the site was well dated with dendrochronology

Målet för hälso- och sjukvård i Sverige är en god hälsa och en vård på lika villkor för hela befolkningen. Hälsovården för barn påverkas av i vilken utsträckning deras föräldrar kan tillgodose sig den information, hjälp och råd de får i barnhälsovården. Syftet med denna studie var att belysa barnhälsovårdssjuksköterskans upplevelse av att främja barnets hälsa i familjer där språket är en barriär.

Somatostatin cells survive in resistant epilepsy Epilepsy is a neurological disorder affecting approximately 1% of the world population annually. It is characterized by persistent episodes of seizures affecting either the whole brain or some parts of it. Secondary epilepsy can be resolved by treating the primary causes but idiopathic (unknown cause) epilepsy has no cure. The treatment in this cas

This Bachelor’s thesis is an anthropological study of the child witch phenomenon in Akwa Ibom State, Nigeria. Children experience extreme forms of violence and neglect of basic human rights, when they are suspected of being witches. As a result of poverty, families experience hardship in everyday life and in trying to understand and explain this, they blame it on the children possessing witchcraft

Developing security regardless of its format is a constant cat and mouse game were adversaries are either in the midst of trying to crack your solution, or they may have already cracked it. A cryptographic algorithm may be unfeasible to crack from a mathematical perspective but as long as a human being is the one developing the solution, a human error is always possible. A large quantity of the

There is a long tradition, especially in phycology, of using 18S rDNA sequences in inferring phylogenies, in particular for higher taxonomic level analysis. 18S like ITS2 displays a conserved RNA secondary structure which could be used simultaneously with the sequence to increase the amount of information available when inferring phylogenetic relationships. In ITS2 research sequence-structure phyl

This essay explores Swedish micro-breweries and their relation to the home market as well as international markets. The Swedish retail market for alcoholic products is heavily taxed and monopolized, affecting the smaller breweries in ways in which to get their products distributed. These micro-breweries have certain geographically relevant rules to follow in order to be allowed to sell their produ

Science fiction and feminist theory have a lot in common. They are both grounded in contemporary times, but envisions another. This essay looks at how women writers have used science fiction to talk about central themes in feminism, namely motherhood and pregnancy. These two are interesting because they are experiences based in the cis-female body. With the assumption that these experiences are pa

Denna uppsats fokuserar på frågan om varför gated communities sprider sig till lägre inkomstgrupper i metropolområdet i São Paulo i Brasilien. För att besvara frågan har fältstudier gjorts och primärdata har samlats in genom att genomföra totalt 57 strukturerade intervjuer och 10 semistrukturerade intervjuer med boende i gated communityt Alphaville 1 i Barueri och Condominio da Sucupira i CarapicuThis thesis focuses on the question of why gated communities are spreading to lower income groups in the metropolitan area of São Paulo, Brazil. To answer the question, fieldwork was done and primary data was collected by conducting in total 57 structured and 10 semi-structured interviews with residents in a the gated communities Alphaville 1 in Barueri and Condominio da Sucupira in Carapicuiba. S

Bhutan is one of the highest per capita users of firewood in the world. Firewood and electricity are the most common methods for heating in Bhutan and both methods suffer from drawbacks. Bhutan’s capitol, Thimphu, lies some 2500 meters above sea level and has cold winters with clear skies. These facts are the base for this report’s investigation of the potential to use solar thermal energy to miti

MAX IV kommer bli världens första ultrabriljanta synkrotronljusring. Ringen använder magneter för att böja elektroners bana på ett helt nytt sätt och kommer därför producera röntgenljus i strålar som blir finare och mer fokuserade än vad någon annan anläggning i världen kan göra. Röntgenstrålarna leds ut i långa rör för att kunna användas till experiment. Ett av strålrören heter NanoMAX och det koX-rays have been used for imaging for over 100 years due to their unique interaction properties with matter that allow them to penetrate samples and reveal detailed structural information on the atomic scale. NanoMAX is one of the first beamlines to be developed at the new Swedish synchrotron radiation source MAX IV. It will use high brilliance, coherent X-radiation to utilize these properties ful

Detta examensarbete undersöker styvhetsegenskaperna för tre armeringsmaterial: ferrocement, glasfiber- och kolfibertextilarmering, tillämpade för skalkonstruktioner. En av de strategier som användes för undersökningen var ett mekaniskt försök med kompositarmerade betongbalkar. Det mekaniska försöket skulle sedan verifieras med numeriska och analytiska modeller. Jämförelser mellan de mekaniska och The purpose of this master’s thesis is to investigate the stiffness properties of three reinforcement materials for concrete shell structures: ferrocement, glass-fibre textile and carbon-fibre textile. Three types of strategies were used to analyse the properties of the materials, an analytical model, experimental beam prototypes and a numerical analysis. Immediate comparison of the mechanical exp

Considering numerical competency in the animal kingdom, primates are thought to be the most advanced ones. Many different studies have showed that also other species such as birds, fishes and amphibians are capable of counting objects and that this ability may be one of the most sophisticated key features for survival. Some lab experiments have revealed that given sufficient amount of training man

The purpose of this essay is to describe the way the prepositions from and från work, both semantically and syntactically. However, the focus is on the translation from from into Swedish. The question this essay aims at answering is: “is there any mutual correspondence between English and Swedish use of their respective prepositions”? The question is relevant since a large amount of the literature

The HIE-ISOLDE post accelerator at CERN has recently come online, en- abling the use of radioactive ion beams with energies of up to 10 MeV/u. An active target gaseous detector is under development for use in some of the experiments. The first investigation of the electron amplification stage with gas electron multipliers has been performed. To this end, a small prototype GEM detector was built an

Zooplankton effects on dinoflagellates vertical migration Diel vertical migration (DVM) is the term used to describe the vertical migration of living organisms up and down along the water column and is common in freshwater and marine environments. This movement is associated to, but not limited to organisms such as: phytoplankton, meso-zooplankton and zooplankton (Bollens et al., 2011). This can b

Syftet med den här uppsatsen är att genom intervjuer med 11 ungdomar i åldern 16- 25, som är födda i Sverige men vars de flesta mor- och farföräldrar kom till Sverige som arbetskraftsinvandrare under 1960- och 1970-talet från forna Jugoslavien (Serbien, Makedonien och Kroatien), undersöka hur de ser på sina identiteter samt sin tillhörighet till det svenska samhället. Ungdomarnas mor- och farförä
