This report is a study in fireworks safety with emphasis on the safety issues considering multiple tube devices. The report was produced in order to facilitate the examination of the risks of firework cakes tipping over during firing, as well as providing support for future studies. The availability of detailed Swedish statistics regarding accidents involving fireworks has proven to be deficient,

The ageing population in Europe has created a demographic shift, especially in the number of pension beneficiaries, which has increased inversely proportional compared to the number of economically active individuals. With the aim of minimizing future pension problems within the EU Member States, the occupational pension system was proposed by the European Commission to integrate the internal pens

Mellan cirka 30-50 procent av den mat som produceras i världen årligen kommer aldrig människan tillgodo som föda. Att mat slängs eller på annat sätt går förlorad i livsmedelskedjan är ett stort problem, framför allt för att många människor i världen inte har tillgång till mat men också för att produktionen av livsmedel medför en betydande miljöpåverkan. Vad gäller statistiken över matsvinnet är deIt is estimated that between 30 and 50 percent of the food produced in the world annually will never be consumed by humans. The fact that significant amounts of food are lost or thrown away in the food supply chain is not just an environmental issue; above all it is a huge problem because many people in the world do not have access to food. Lost food and waste appears throughout the whole food sup

Aktieägaravtalet är ett populärt komplement till de vanliga aktiebolagsrättsliga styrdokumenten. Det syftar till att ytterligare reglera aktieägarnas mellanhavanden och associeras med en rad kommersiella fördelar så som avtalsfrihet och konfidentialitet. Däremot har aktieägaravtalets bolagsrättsliga verkningar under många år varit föremål för diskussioner. Den gängse uppfattningen har länge variThe shareholders’ agreement is a popular complement to the articles of association. It seeks to further regulate shareholders' dealings and is associated with a range of commercial advantages such as freedom of contract and confidentiality. However, the company law implications on the shareholders' agreement are still subject for discussions. The prevailing view has long been that the sha

Can it still be theatre? By building my own experimental theatre production containing flash mobs and invisible theater and then analyzing the results I hope to find a way how to aggrandize and help the invisible theatre to take more space. Also by comparing and analyzing the concepts of art and anti-art, acting and not-acting with my own theatre production I hope to find some clarity in the conce

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

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

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
