The present work provides a new perspective on super adiabatic combustion (SAC) of fuel/air mixtures involving methane, ethane, propane, butane, heptane, iso-octane, 1-hexene, toluene, ammonia, and hydrogen. The simulations cover the temperature range of 1200–2000 K, initial pressures of 1–50 atm, and equivalence ratios of 0.5–2.0. The detailed chemical kinetic mechanism C3MechV3.5 has been used f
This thesis consists of three essays on VIX futures and options, and deals with issues highly relevant to all financial markets, such as understanding the operation of markets and developing flexible and tractable pricing models for contracts traded in them. It consists of four chapters. Chapter 1 provides a short introduction to the VIX and a brief explanation of how the old and new VIX are cons
Barnhandel är rekrytering, transport, överföring, inhysande eller mottagande av ett barn i syfte att exploatera hen. I Sverige, som i första hand är ett destinationsland för barnhandel, identifieras ett 50-tal barn per år som offer för människohandel. Antalet okända fall uppges dock vara betydligt högre. Med barn re-trafficking avses varje situation där ett barn som har brutit sig loss från en mänChild trafficking is the recruitment, transportation, transfer, harbouring, or receipt of a child for the purpose of exploitation. In Sweden, which primarily is a country of destination for child trafficking, around 50 children per year are identified as child victims of human trafficking. However, the number of unknown cases is said to be significantly higher. Child re-trafficking means any situa
Att byggsektorn står inför ett rådande klimatnödläge är ett faktum. Idag investeras hundratals miljarder kronor för att i framtiden kunna producera fossilfritt stål; trots det läggs lite fokus på miljöoptimering av konstruktioner. Syftet med arbetet är att utvärdera hur parametrisk design kan användas som verktyg för att miljöoptimera stålstommar i industritrapptorn samt undersöka vilken profiltypThe fact that the construction sector faces a prevailing climate emergency is undeniable. Today, hundreds of billions of kronor are being invested to develop fossil-free steel; yet little focus is placed on environmental optimization of constructions. The purpose of this work is to evaluate how parametric design can be used as a tool for environmental optimization of steel staircase towers, as wel
I ett samhälle där bilismen ökar blir en mer hållbar bilism allt viktigare. Sverige har satt upp som mål att ha en fossiloberoende fordonsflotta till 2030 och en helt fossilfri fordonsflotta till 2050. För att kunna uppnå detta spelar elbilen en viktig roll. Genom intervjuer med olika aktörer på den svenska marknaden visas i detta examensarbete att en stor tilltro sätts till elbilen, vid sidan av In a society with growing car mobility, sustainable motorism becomes increasingly important. Sweden has set targets of having a fossil fuel independent vehicle fleet by 2030 and a fossil free vehicle fleet by 2050.In order to reach these targets the electric car plays an important role. Through interviews with different actors on the Swedish market, this thesis shows that much confidence is put in
Godstransporter på väg står för ungefär 7 % av Sveriges totala växthusgasutsläpp och godstransportarbetet förväntas öka med drygt 65 % till år 2040, delvis till följd av ökad globalisering. Enligt IPCC:s senaste rapport är transportsektorn ett prioriterat område för att begränsa miljöpåverkan och den statliga utredningen om fossilfri fordonstrafik pekar ut minskad användning av fossila bränslen ocHeavy transport accounts for about 7 % of total Swedish greenhouse gas emissions and freight activity is expected to increase by more than 65 % in 2040, partly as a result of globalization. According to the latest report from IPCC, the transport sector is a priority to limit the environmental impact and the government report on fossil fuel independence proposes reduced use of fossil fuels and incr
All buildings need a foundation that supports the structure. Since a layer of soil is most often in between a structure and the bedrock, a soil-structure interaction between the foundation and the soil beneath occurs. This interaction is of great importance when it comes to predicting the sectional forces that will arise in a structure, along with the settlement that occurs. Therefore the need to
Den fria bevisprövningen är den mest grundläggande principen i svensk bevisrätt. Det finns därför inget principiellt hinder mot så kallad karaktärsbevisning. Trots det är karaktärsbevisning alltjämt föremål för diskussion i den bevisrättsliga litteraturen. Den här uppsatsens syfte är att undersöka tillåtligheten och värdet av karaktärsbevisning i svensk rätt, både genom en deskriptiv undersökning The principle of free presentation and evaluation of evidence is the most fundamental principle in Swedish evidence law. Consequently, there are no general prohibitions against so called character evidence. Despite this, character evidence is a frequent object of discussion in evidence law literature. The purpose of this thesis is to examine the admissibility and value of character evidence in Swe
Purpose: In this study, we examine the data from Chinese companies to test the relationship between cash flow and investment. While a wide assortment of previous research has examined the relationship between cash flow and investment, they have largely focused on empirical analysis from an US or a Western perspective. But, to date, little attention has been paid to such relationship using empirica
BackgroundShock is a condition with high mortality even with early intervention and treatment. Usual care for shock and hypotension in the Emergency Department (ED) is intravenous fluid resuscitation which can lead to fluid overload and other complications. When fluid therapy fails or risk of complications are high, the next treatment step is the use of vasopressors for stabilisation. Noradrenalin
Introduction: Cardiotocography (CTG) is the main method of intrapartum fetal surveillance. In 2015 a new guideline was introduced by the International Federation of Gynecology and Obstetrics (FIGO), FIGO-15. In Sweden it was adjusted to SWE-17, replacing the previous national template, SWE-09. This study, conducted at one university hospital and one regional hospital in southern Sweden, evaluated
Background: There are two conceptually different surgical treatment options for patients with T1 colorectal cancer (CRC): radical surgical resection and local resection. In addition, adjuvant chemotherapy is recommended in cases with lymph node metastases. However, surgical overtreatment of early CRC is a concern and may be related to limitations in preoperative work-up as well as tumour risk clas
It has been demonstrated that prostate-specific antigen (PSA), in spite of its name, can be detected in body fluids and tumors from a variety of organs. Investigations have shown that human glandular kallikrein 2 (hK2), a related prostate-secreted protease, can activate the zymogen form of PSA, suggesting that the two enzymes might work as a functional unit, with hK2 as the activator molecule and
Popular Abstract in Swedish Medeltemperatur på jorden har stigit med ca 0.6 ºC sedan 1900-talets början. Denna ökning beror mycket sannolikt på människans utsläpp av växthusgaser så som t.ex. koldioxid. Under det kommande århundradet räknar man med att jordens medeltemperatur kommer att stiga ytterligare 1.4-5.8 ºC. Både temperaturhöjningen och koldioxidhaltens ökning i atmosfären kan påverka vegeSome components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground. In this work some of the mechanisms of the below-ground C cycle in subarctic ecosy
This thesis consists of a collection of essays on coordination in games and competition in international oligopolies. The first essay presents a theoretical analysis of a simple coordination game in which players simultaneously choose efforts from a compact interval. The original game has a continuum of Pareto-ranked equilibria. In a noisy variant of the model an error term is added to each player
Popular Abstract in English “We are not free in this area.” This is what the iNduna, a traditional leader at KwaDapha, shared with me when we first met in August 2011. KwaDapha is a small rural community at Bhanga Nek, Kosi Bay, in northern KwaZulu-Natal/Maputaland – one of the most scenic areas on the South African coastline. Kosi Bay falls within the Coastal Forest Reserve section of the iSimaIn the past several decades under a growing influence of ecological modernisation, various assumed ‘win-win’ approaches to protected area conservation and poverty alleviation have been introduced all over the world, especially in resource-rich developing countries. Yet protected area conservation is an inherently political process, and the goals are often not achieved. There are concerns about com
Popular Abstract in Swedish Nematod-fångande svampar är en grupp av filamentösa svampar som lever i jorden. De kan som deras namn antyder fånga och infektera nematoder. Varför är det då viktigt att studera dessa svampar? Svaret är just nematoder. Nematoder, även kända som rundmaskar, kan infektera både människor, djur och växter. Vi i Europa är relativt förskonade mot dessa infektioner om man jämfNematode-trapping fungi are soil-living organisms with the unique ability to capture and infect free-living nematodes. The interest in studying these fungi arises from their potential use as biological control agents for plant- and animal-parasitic nematodes. To enter the parasitic stage, nematode-trapping fungi develop different kinds of trapping structures. In order to understand more about the
This dissertation investigates the relation between aesthetics and politics by interpreting three experimental novels by Virginia Woolf, Djuna Barnes and Gertrude Stein. By theorizing the relation between language, subject, voice and ideology it questions the autonomous subject as a ground for political action and criticality. This is done by challenging language as a vehicle for individual expres
Popular Abstract in Swedish Det finns över 500 kräftarter i världen och vi hittar dem på alla kontinenter utom Antarktis och Arktis. I Sverige finns två arter, den inhemska flodkräftan och den introducerade signalkräftan. Signalkräftan introducerades till stor del för att ersätta förlusten av flodkräfta i många pestdrabbade vatten i södra Sverige. Att det just blev signalkräftan berodde främst på In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis. Overall, the results show that abundance of crayfish is mostly affected by the abundance of predatory
