Problem/Bakgrund: I dagens moderna samhälle tillbringas allt mer tid till att vara verksam inom sociala medier. Bloggar som dagligen besöks av unga flickor är ett sätt att se hur andra har det vilket influerar dem till att vilja leva ett problemfritt liv och därför är det intressant att titta närmare på om det påverkar deras identitetsskapande. Syfte: Syftet är att undersöka om unga flickors ident

The world is currently facing a number of large environmental challenges, and cleantech is pointed at to be one of the best potential answers. However, in the winds of a financial crisis, shifting capital markets and rapidly growing information technology sector, the cleantech segment currently finds itself in a disadvantaged situation where the direly needed early-stage capital is not finding its

In this master's thesis, a copula approach is used to model the number of claims made by a customer holding three insurances. It is important for insurance companies to have good models for the risk proles of their customers, and the number of claims is a key element in calculating the expected cost for the company. Using copulas, multivariate distribution functions are allowed to have any des

The nanowires technology has proved itself to be fairly promising in order to develop more ecient optoelectronic devices such as solar cells and LEDs. It becomes therefore interesting to be able to characterize nanowires samples with a high precision, so that the light emitted from each single nanowire can be detected and analyzed. The purpose of this thesis project was to test if solid immersion

Populärvetenskaplig sammanfattning Metallorganisk kemi är en gren av kemin som fokuserar på att utveckla nya reaktioner med hjälp av övergångsmetaller som t.ex. järn, kobolt och guld. Genom att använda övergångsmetaller i kemi är det möjligt att bilda nya reaktioner som man med konventionell organisk kemi inte kan få tillgång till. Dessutom är selektivitet, avfallsminskning, minimering av biprodukSeveral N-heterocyclic gold (I) complexes were synthesized featuring both the bis-(2,4,6-trimethylphenyl)imidazolium carbene (IMes) ligand and the bis-(1,3-diisopropylphenyl)imidazolium carbene(IPr) ligand. Complexes of the form LAuCl, LAuOtBu, and LAuPh (L = IMes, IPr) were synthesized and characterized using 1H-NMR. Two updated crystal structures of IMesAuPh and chloro(dimethylsulfide)gold(I) we

Popular science summary: What the zebra finches did not see There is more out there than what we can see; that is something that most people would agree on. And I am not talking about ghosts from the beyond or aliens from space; I am talking about all those things that we know exist but that we are not able to see with our own eyes or feel with our own senses. I am not talking science fiction, I

Bart Streumer utilizes the principle “R: We do not have reasons to do what we cannot do” in order to justify that ‘ought’ implies ‘can’. This thesis questions Streumer’s assumption and instead argues that we have reasons to do what is psychologically-, physically and maybe even metaphysically impossible but not conceptually or logically impossible. As is shown in the thesis we do not have reasons

Concerns about the decline in knowledge concerning food growing stemming stem from the Green Revolution, as well as the rapid urbanization since the beginning of the 20th Century. There is a gap in the literature about community gardening in industrialized English-speaking countries, and since sharing of knowledge is a well-documented achievement of community gardens, the aim of this thesis is to

In February 2013, the United States and the European Union announced to start negotiations on a comprehensive Transatlantic Trade and Investment Partnership. If these negotiations lead to a free trade agreement between the United States and the European Union, the two markets together will form the largest trading bloc in the world. The US and EU are already each other’s main trading partners and

Populärvetenskaplig sammanfattning Protein-protein växelverkan för det globulära proteinet laktoferrin har studerats vid låg elektrolythalt (5 mM) med hjälp av statisk ljusspridning och mätningar av andra virial koefficienten, B2 som innehåller information om protein-protein växelverkan. Växelverkan mellan proteinmolekyler är mycket komplex vilket beror på de ingående aminosyrornas egenskaper. DesIn this work the effect of pH and ionic strength on interactions for the globular protein lactoferrin has been studied using static and dynamic light scattering. The interactions were investigated in terms of the second virial coefficient, B2, and the collective diffusion coefficient, Dcoll, at different concentrations of electrolyte. The conditions investigated in this work will serve as a stable

Idag tillhör persondatorerna våra käraste prylar, men så har det inte alltid varit. Kring 1980, då persondatorerna slog igenom i Sverige, sågs "datafrågorna" istället tillhöra samhällets stora utmaningar, tillsammans med bland annat energiförsörjningen och miljöfrågorna. Dessa datafrågor debatterades häftigt, och i fackpressen kritiserades särskilt Sveriges Television för att ge en allde

In times of increased environmental awareness, there exists a desire to not only build new environmentally friendly and renewable power generating units, but also to increase the efficiency of all existing technology. Wind power is such a renewable and environmentally friendly technology. Wind turbines and wind power have made giant leaps in the world in the past years, with an almost exponential

The purpose of this study is to explore if and how the situation for women in India and Bangladesh changes through microloans. In this thesis I describe what microloans are about, what empowerment is and how Grameen Bank works. The data for this study consist of anthropological research and field studies as well as statistical data, which have been analyzed using from a perspective of applied ant

Bakgrund Att ha rätt mängd varor, vid rätt tid och på rätt plats är ett centralt problem i färskvarubranschen. För att ta itu med denna problematik har författarna undersökt i vilken utsträckning avancerade prognosmodeller kan hjälpa branschen med detta problem. I arbetet undersöks effekterna av både enkla och avancerade modeller och jämförs med manuella prognoser som görs av säljarna på Pågen AB.

FTRTIL is rapidly expanding on the Indian market after initiatives by the Indian government to increase the number of rolling trains. FTRTIL is today experiencing a greater demand for their products. Meanwhile are they also planning to expand their product range with new introductions. After trying to respond to the prevailing market demand for the E70 brake panel without any success made FTRTIL r

Ekosystemtjänster är ekosystemens direkta och indirekta bidrag till människors välbefinnande. Ekosystemtjänster är ett forskningsområde som får en allt större uppmärksamhet internationellt, men också i Sverige. År 2006 gav regeringen Naturvårdsverket i uppdrag att ta fram en vägledning för tillämpningen av ekosystemansatsen i Sverige och regeringen fastslog 2012 att betydelsen av biologisk mångfal

Popular science summary Is the European hake “shrinking” under the current fishing practices? Did you know that the current fishing practices have caused significant declines in body size of many exploited fishing stocks? This effect of fishing management has become one of the major threats for commercially exploited fish species and it can have severe negative consequences for the offspring of

Popular science summary Are aerial drones the future for wild boar crop damage surveys? The wild boars are back, and they have returned in force. This is a rather recent trend since wild boars were extinct in Sweden until the 1970s and since then they have multiplied explosively, spreading all over central and southern Sweden. Their re-appearance has led to conflicts with human interests, namel
