Popular science summary Complex I, let me see your true color Every day of our lives our body performs many different tasks to let us survive, such as brain activity, muscle contractions or smaller tasks like cell- repair or -division. All those tasks require energy. The energy currency of our body is called ATP (adenosintriphosphate), a molecule that lets us perform many reactions in our body.
This study investigates the possibility of intentional forgetting of congruent and incongruent stereotypes belonging to either the in-group or an out-group. Previous research has shown that we perceive people differently depending on whether they belong to our in-group or an out-group. Differences have also been shown in how we process information that is congruent or incongruent to a stereotype.
Populärvetenskaplig sammanfattning Ska du flyga långt med de där vingarna? Vissa fåglar flyger långt, andra inte. Silvertärnorna flaxar med vingarna från Arktis till Antarktis medan pingvinerna använder vingarna för att simma och inte flyger alls. Eftersom att olika fåglar använder sina vingar på så olika sätt så har nämnda vingar anpassats efter vingbärarnas behov. Vissa studier har visat sambaAbstract Bird wings are adapted to the needs of the birds and bird wings therefore differ between species, but also between ages and sexes. In this thesis, an interspecific analysis investigating relations between measurements of wing shape for birds within the Sylviidae-family, revealed strong connections between morphologically unrelated measurements. Long distances (compared to the wing length
This thesis was conducted to assess how the broadening of trade, through Internet-enabled businesses and commerce, was affecting economic, social, and environmental sustainability. It identifies the threats and opportunities associated with the expansion of trade online, in addition to evaluating some of the implications a changing trade and commerce landscape could have on trade rules and policy.
Problem/Bakgrund: Den afrikanska växtdrogen khat används främst av folkslag från Afrikas Horn samt den arabiska halvön. Med en utökad flyktingström från dessa områden, främst Somalia, till bland annat Europa, så har även khatbruket spridits på liknande sätt i världen. Den somaliska folkgruppen upplevs som svårintegrerade som en minoritetsgrupp, och khatbruk ges delvis skuld för detta. De vetenskap
This thesis is about time-frequency analysis of the brainstem auditory evoked potential (BAEP). The work can be divided into two parts. One part where a model is built up from a very simple example to a more complex model resulting in a model consisting of a sum of sinusoids with stochastic starting points and amplitudes. Dierent time-frequency methods have been evaluated for these models and the
To inpaint a digital image is to fill in unwanted pixels in an image with other, plausible, content. One use of this is to remove unwanted objects in a photograph. A user marks the unwanted objects, and then the objects should automatically disappear. There are many ways to inpaint images, and one of them is so called exemplar-based. This means that other parts of the image is copied into the area
The purpose of this thesis is to investigate the relationship between trade diversity and growth in the East African Community. This was done by measuring different levels of diversification in exports and further test if they could contribute to explaining the different growth levels between member countries. Using data collected for the five member countries; Burundi, Kenya, Rwanda, Tanzania and
Syftet med studien var att få en fördjupad förståelse för bondage/disciplin/dominans/underkastelse/sadomasochism (BDSM) gällande vad BDSM-utövande fyller för psykologiska behov, vilka psykologiska processer som sker i relationen till utövarnas sexpartners samt hur utövarna påverkas av att ha en normbrytande sexualitet. Fem självdefinierade BDSM-utövare, kvinnor och queerpersoner, som utövar sexuelThe aim of the study was to gain a deeper understanding of bondage / discipline / domination / submission / sadomasochism (BDSM) regarding psychological needs, psychological processes in relation to practitioners' sexual partners and how practitioners are affected by having a non-normative sexuality. Five self-defined female or queer BDSM-practitioners who practice sexual dominance in a BDSM c
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
