Hypervelocity stars, på svenska hyperhastighetsstjärnor, är stjärnor som observerats med så hög hastighet att de kan lämna vår galax, Vintergatan. Den första hyperhastighetsstjärnan upptäcktes av R. Brown m. fl. (2005), och sedan dess har många fler upptäckts. J. G.Hills presenterade (1988) en teori om att hyperhastighetsstjärnor härstammar från binära stjärnor (två stjärnor som kretsar varandra) In this thesis, I investigate if the binaries that are being tidally disrupted by means of the Hills mechanism, producing hypervelocity stars, could have been transported to the galactic centre by two-body scattering. To survive a scattering event, the binary must be hard, meaning that the binding energy of the binary is higher than the kinetic energy of the collider. If the binary is soft, the bi

Maskar och ärrvävnad - Hur påverkar det färgen hos fisk? För att överleva olika typer av infektioner är det viktigt att immunförsvaret fungerar. Det kan dock också vara kostsamt att ha ett immunförsvar. Ett exempel är feber. Kroppen slår tillbaka mot en infektion, men själv känner en sig inte direkt manad till mycket annat än att sova. Kroppen måste avväga vad som är viktigt att lägga energi på vTo understand why immune traits affect the fitness of its host is an important part of understanding why and how immune responses evolve. In threespine stickleback (Gasterosteus aculeatus), fibrosis is an immune response evolved to combat infection of the tapeworm parasite Schistocephalus solidus. Already known is that fibrosis leads to a reduced mating success for males. Here I investigated wheth

Konsignation är ett handelsupplägg som i näringslivet främst används i avtalsrelationen mellan leverantörer och återförsäljare. Upplägget går ut på att leverantören, konsignanten, deponerar varor med bibehållen äganderätt för förvaring i ett varulager hos återförsäljaren, konsignatarien. Konsignatarien har därefter en rätt att göra uttag från lagret på kredit, som ofta sker i samband med vidareförConsignment is a form of trade arrangement most frequently used between suppliers and retailers. The point of the arrangement is that the supplier, the consignor, places goods with contained ownership for storage at the possession of the retailer, the consignee. The consignee then has a right to withdraw goods on credit, often in connection to the sale to a third party. The capability of the arran

Surrogatskap är en aktuell och omdebatterad fråga. Varken altruistiska eller kommersiella surrogatskap är tillåtna i Sverige. Surrogatskap är en relativt ny företeelse och diskuterades för första gången på 1980-talet i riksdagen. Till en början var de flesta partier restriktivt inställda och talade om surrogatskap som en främmande och osedlig företeelse. Med åren öppnades det dock upp för en diskuSurrogacy is a current and often debated issue. Neither altruistic nor commercial surrogacy is allowed in Sweden. When surrogacy was first discussed in the 1980s most parties were restrictive and spoke of surrogacy as a foreign and immoral phenomenon. Over the years, however, more parties have opened up for discussing the matter. In SOU 2016: 11, the possibility of surrogacy in Sweden was investi

I Sverige dör cirka 90 000 personer varje år. Dessa 90 000 personer har vanligtvis tillgångar och skulder som inte upphör i samband med dödsfallet. Skulder måste betalas och tillgångar fördelas i enlighet med den legala arvsordningen, eller i förekommande fall, i enlighet med ett testamente. Utgångspunkten är att det är de som har rätt till tillgångarna och som påverkas av förvaltningen som ska taEvery year about 90,000 people die in Sweden. These 90,000 people normally all have assets and liabilities that do not cease to exist by reason of demise. Debts must be paid, and assets distributed in accordance with legal succession or, when applicable, in accordance with a last will and testament. The general rule is that it is those who are entitled to the assets and, who are also affected by t

In association with the refugee crisis in 2015, more people sought asylum in Sweden than ever before. The Swedish government initially pursued a relatively welcoming asylum policy with open borders and with a vision of maintaining the right to asylum. This moral attitude towards refugees would subsequently take a turn. On December 9 in 2015, the Bill "Specific measures during serious danger t

Uppsatsen behandlar det adopterade barnets ställning inom adoptionsinstitutet genom dess förändring över tid. Adoptionsinstitutet har förändrats i takt med samhällsutvecklingen och lagstiftaren har tidvis försökt lösa samhällsproblem med hjälp av lagstiftningen. Uppsatsens syfte är att undersöka hur barnets ställning har förändrats tillsammans med adoptionslagstiftningen. Adoption som ett institThis thesis examines an adopted child’s status within the adoption institute through time. The adoption institute has changed in line with the development of society and the legislator have occasionally tried to solve problems occurring in the society with the help of legislation. The child’s status is dependent on society’s perception of children and the reign values in the general public. The

This essay is inspired by the debate in Sweden today, about whether a ban on veiling should be introduced in the Swedish preschools and elementary schools. With a criminal-law perspective, this essay examines motions filed by political advocates for a ban and evaluates the compatibility of their arguments to Nils Jareborg's and Claes Lernestedt's criminalization principles. Simultaneously,

Det är, med tanke på mängden avtal som sluts varje dag, omöjligt att förhandla om villkoren i varje enskilt fall. Istället används standardiserade avtal i allt högre utsträckning. Standardavtalen är ofta ensidigt upprättade av den starkare avtalsparten. Det finns en risk för att villkoren är väldigt förmånliga för den parten. Domstolarna använder dold och öppen avtalskontroll för att motverka sådaThe large amount of agreements in today’s business world makes it impossible to negotiate the terms in every individual case. Instead, the use of standard agreements is increasing. The terms are often dictated by the strongest party. There is a risk that the standard agreements are unilaterally advantageous to that party. Such contracts are counteracted mainly in two ways: open and concealed judic

This paper analyses the Swedish government and the Swedish central bank's measures during the coronavirus pandemic and their effects on the economy in the short run and potential long run effects. By comparing the covid-19 pandemic with the Swedish crisis in the 1990s, and the financial crisis 2008-2009, differences and similarities are combined with previous studies to analyze what effect the

Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita

The purpose of this study is to evaluate what impact the conflict in Afghanistan has had on the democratization process in the country. Almost twenty years have passed since the US-led invasion and the overthrow of the authoritarian Taliban regime in a response to the 9/11 attacks on American soil. The goal with the invasion was not only to catch Usama bin Ladin, but also to replace the religious

The principle aut dedere aut judicare can be found in international cooperation concerning extradition for criminal offences. The meaning of the principle is that if a state refuses to extradite a person, often on the grounds that the person is a citizen of that state, the state can undertake to prosecute the person for the crime he or she is suspected of. The focus of this thesis has been to inve

The aim of this thesis is to describe and explain how meal-box, as a digital device designed to assist households in carrying out eating practices, reconfigure household practices and enable specific behavioural activities, including sustainability. Taking a socio-material and practice theory approach and drawing on an ethnographic study of three meal-box providers – The Seasons, Hello Fresh and L

Since the 1950s, no other material has been developed and used to the same extent as plastic. We have built up a society that has integrated plastics into virtually every aspect of our lives. With low material prices, cheap manufacturing methods and its versatility, plastic has quickly become a commodity in society that is consumed in an unsustainable way. Plastic pollution causes immense social,

When organizations choose between leasing and owning facilities there are benefits and drawbacks associated with both alternatives. If an organisation proceeds with a middle ground solution by leasing using a triple net lease, they will instead face challenges unique for that lease type. The aim of this thesis is to find out how companies can take advantage of triple net leases and what the requ

This thesis studies the impact of the war in Ukraine on stock prices of firms within the European defense industry. While previous studies have examined the effects of war on stock prices of defense firms, fewer studies specifically focus on the war in Ukraine. Furthermore, this thesis focuses solely on European defense firms, offering a new geographical perspective to the topic. Additionally, the

Global investment decisions are increasingly prioritizing sustainability, and this study examines how firm-level practices toward sustainability have the potential to attract foreign ownership. Focusing on the Eastern European and Central Asian (EECA) region, the interaction between foreign direct investment (FDI) and sustainable management practices within the context of middle- to upper-middle-i

Principen jura novit curia är en central och vedertagen princip i svensk processrätt och tillämpas i domstolsprocessen. Principens relevans och tillämpning i skiljeförfarande är dock inte lika självklar mot bakgrund av skiljeförfarandets syften och bakomliggande principer. Frågan om en skiljenämnd kan, bör eller ska tillämpa principen jura novit curia på motsvarande sätt som i domstolsprocessen akThe principle of jura novit curia is a central and well-established tenet in Swedish procedural law, applied within court proceedings. However, its relevance and application in arbitration is not as clear, given the purposes and underlying principles of arbitration. The question of whether an arbitral tribunal can, should, or must apply the principle of jura novit curia in the same manner as in co

ICTR, ICTY och ICC har tolkat rekvisitet ”avsikt att helt eller delvis förgöra en nationell, etnisk, rasmässigt bestämd eller religiös folkgrupp” i artikel II i FN:s folkmordskonvention som dolus specialis. Denna tolkning av upp-såtskravet har kritiserats av många på grund av dess stränga uppsåtskrav. Följaktligen har olika alternativa tolkningar utvecklats i doktrin. I detta avse-ende undersöker The prevailing view in the international case law interprets the “intent to de-stroy, in whole or in part, a national, ethnical, racial or religious group” re-quirement in Article II of the Convention on the Prevention and Punishment of Genocide as a special or specific intent (dolus specialis). This interpretation of genocidal intent has been criticized by many scholars regarding its stringent re
