Crude oil is the most traded energy commodity in the world, and its price has a large impact on the everyday life of billions. Given the volatility of crude oil prices and its enormous effects on economies worldwide, there has been a growing demand for risk quantification and risk management for the market participants. The measurement known as Value-at-Risk (VaR) has become the industry standard
The purpose of this research is to conduct a critical study which focuses on getting deeper insights into in-application advertising, especially, to understand the details of making in-application advertising, and to develop the existing advertising model for applying to the in-application advertising specifically.
"There is a crack in everything. That's how light gets in." With two simple sentences the famous poet Leonard Cohen describes his perception on how light interacts with matter. This thesis work will try to give a more precise and detailed description of the interaction between light and nano-materials that maybe is going to lose some of the magic that poetry has but this will be com
All industrial facilities and large warehouses require some sort of lighting solution. They have ongoing activities with workers and trucks moving around at various speed, and to avoid accidents these lighting solutions are often very bright and energy consuming. The most common solution is fluorescent light. These lights are energy consuming and not dimmable. Turning these off by night or when th
Abstract European blackberries constitute a polyploid complex of closely related microspecies, which includes species in Rubus sect. Rubus and Rubus sect. Corylifolii of Rubus subgenus Rubus. These species reproduce by facultative agamospermy. New microspecies evolve from time to time by hybridization between Rubus sect. Rubus and R. caesius or R. idaeus, or by sexual reproduction. Because of the
In this study bryophyte species richness, abundance and sexual reproduction was screened in sampling plots in a planted costal Scots pine forest set in a logging system in Southern Sweden, with control plots in the adjacent nature reserve. Data was collected from seven different stands, with equal stand structures in a chronosequence after commercial thinning; data was in the same way collected fr
Dissolved ammonia is often referred to as one of the major contaminants in landfill leachates. Discharge concentration limits for municipal wastewater treatment plants in Sweden have been tightened in order to meet higher water quality standards. Because of REVAQ, a certification system tailored to ensure better sludge quality, wastewater treatment plants may decide whether to accept leachate from
Food trucks provide personalized experiences by eliminating anonymity and allowing the customer to slow down and engage. Their mobility facilitates transformation and a sense of occasion, thus possessing elements of performance, urgency and excitement. Having the ability to define spaces and revive locations, food trucks creates affiliative communities with natural meeting locations. The food truc
In several years after its discovery in the placenta, the human leukocyte antigen (HLA) class lb protein, HLA-G, was not given much attention, nor was it assigned great importance. As time has unraveled, HLA-G has proven to have distinctive functions and an unfore seen and possibly important role in reproduction. HLA-G is characterized mainly by its low polymorphism and restricted tissue distribu
MicroRNAs (miRNAs) are an exciting new field which has been connected to different cancers and cellular imbalances. In previous studies, our group has been able to find a correlation between miR-96 and prostate cancer (PC). Here we studied miR-96’s effect on the cell-cell adhesion protein E-cadherin’s RNA and protein expression levels upon miR-96 inhibition. Furthermore, because the bone is one of
The life stages of the sciarid fly Scatopsciara cunicularius and the effect of 3rd & 4th instar larval feeding on the bryophyte liverwort Marchantia polymorpha were studied in laboratory at two constant temperatures, 12.3 ± 0.6 ºC and 22.6 ± 1.7 ºC. A 14-hour period of light was provided during the 24-hour day/night-cycle. The experiments were carried out inside Petri dishes, at a relative hum
Vårt syfte med detta arbete var att undersöka hur synen på ojämlikheter bland barn och unga ser ut idag och vi valde att göra detta genom att samla in information från verksamma inom barn- och välgörenhetsorganisationer. Vi ville undersöka hur de diskuterar ojämlikheter, deras konsekvenser och i vilka sammanhang de anser att de uppkommer. Vi intervjuade fem personer, från olika organisationer, och
The focus of this work is to investigate and apply the remote sensing method of object-based image analysis (OBIA) for vegetation classification of a permafrost underlain peatland in sub-arctic Sweden, by using aerial imagery of high resolution. Since the northern landscapes are an important source of naturally stored CH4 and CO2, their contribution to the global carbon cycle is a focus in researc
This paper contains a study of the Nobel Peace Prize winner Liu Xiaobo’s texts on the Iraq war, and the implications of the problem representation encompassed in his view on the war. By use of the “What’s the problem represented to be?”- approach by Carol Bacchi, I have found that the problem representation in Liu Xiaobo’s texts on the Iraq war is “lack of democracy and freedom”. Because of the pr
Purpose: The purpose of this paper is to assess the sustainability of the efficient market theorem when accounting for extreme events, which are of the essence in a Black Swan investment philosophy. Methodology: Quantitative approach. Empirical foundation: Historical secondary monthly and daily data of various variables during January 1, 1996 - December 31, 2012. Conclusions: The Black Swan inv
Being the host of an Olympic Game can change the image of a city forever. The games last for only a month but the preparations begin many years before and the legacy lasts many years to come. In order to host the Olympic Games of 2008 Beijing underwent major changes and tore down old neighborhoods and replaced them with brand new buildings. Huge arenas, new landmarks, which will always be connecte
Glaciärer har visat sig vara känsliga för klimatologiska förändringar i sitt närområde och deras känslighet sträcker sig över flera olika tidsskalor. Glaciärerna har därför kommit att användas som indikatorer på både pågående och förhistoriska klimatförändringar. För att glaciärerna ska kunna spegla klimatet så krävs emellertid tillförlitliga mätmetoder av glaciärernas massa. I avsikt att återge gGlaciers integrate variations in climate over several different time scales and are thus used as indicators of both present and past climate change. It is however of importance to be able to correctly measure changes in the glaciers mass over time (the glaciers mass-balance), if one wishes to use the glaciers as climate indicators. The mass-balance of a glacier is a direct result of the glaciers a
