This paper examines the carbon price dynamics in the European Emission Trading System (EU ETS). It seeks to answer whether these can be explained by marginal emission abatement costs, as stated by theoretical propositions. The primary abatement method, fuel switching, and other potential determinants are examined to test their relative importance in carbon price dynamics. The results from the perf
Periodic Shadowing is a software post-processing technique for suppressing stray light. A proof-of-concept was recently published so an analysis of the involved parameters is needed to allow for a deeper understanding of the technique. In this project the three most important parameters in the technique are analyzed and their impact on the results of optical spectroscopy measurements is evaluated
Denna uppsats är skriven vid institutionen för kommunikation och medier vid Lunds Universitet. Den författades av Jakob Lundgren och Adam Mattebo under ämnet media- och kommunikationsvetenskap och den är skriven på en B-nivå. Uppsatsens syfte var att undersöka om användandet av mobilapplikationen Snapchat, som växt väldigt snabbt de senaste åren, skiljde sig åt från andra sociala medier. Uppsatsen
The Japanese language has as any other language been grammaticalized throughout history. Many different aspects regarding the Japanese language has at some point underwent this phenomenon. However, the aspect that will be considered in the following disquisition is the Japanese auxiliary verbs, with consistent focus on the two verbs oku and shimau. These two verbs have when used a grammatical mark
Income inequalities in developed nations are increasing and the issues of cause, effect and long run implications are currently being discussed and explored by economists and policymakers around the world. This thesis adds to the discussion by exploring income growth in Sweden; a country known for its equality and egalitarian society, yet has become one of the countries where income inequality is
Objective: Citrate is widely used in dialysis, either as an acid in dialysis fluids or as a regional anticoagulant. In both cases, the concentration of citrate in the plasma of the patients will increase above physiological levels, up to 5-foldes in some cases. The aim of this study was to investigate the effect of citrate on the transcriptional level, as well as on the metabolic level and elucida
The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2. A ch
På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. Efter en omfattande litteraturstudie har det framkommit att elbehove
Climate change is a people-made crisis which requires a shift in our mindsets. Early studies in the field of mindfulness within sustainability science show the potential of mindfulness to influence consciousness, beliefs, and values for sustainability. However, the field is still at its early stages and scattered over various topics and methods. The aim of this thesis is to assess how the concept
Recently, several academic studies have proposed a theoretical ‘producerist framework’ to address the lack of research and conceptual clarity on the economic dimension of national populism. Essentially, this framework refers to a narrative that pits the producers, understood as citizens that contribute to the nation’s economic wealth, against parasitic takers, who threaten the producers’ well-bein
The main purpose of this project has been to model one steam heated cylinder, which was taken as part of a drying section, moreover the design and structure of an existing process has been taken in consideration.
To develop this work ModelicaTM software has been used. Particular attention has been paid to reproduce the two time constants behavior of the dynamics in the pressure
Interlinked control loops with asynchronous sampling can give rise to a time varying time delay which varies irregularly. Here we examine ways to model these effects for an arbitary number of control loops, and to build up a probability density function, and current delay, before implementing a controller.
Modelling of an industrial control loop for concentration control using Omola, an object-oriented modelling language, is described. The major modelling effort has been made to make a complete nonlinear model of the pneumatic positioner-actuator of the control valve in the loop. A library of several friction models has also been developed. These models have been used to describe friction in the con
Sandvik Coromant is the market leader of producing tools for advanced metal cutting. The tools are produced in cemented carbide, however Sandvik Coromant does not produce tools for machining cemented carbide. The aim of the thesis was to perform cutting tests in cemented carbide with diamond tools to investigate if the binder content affected the machinability of the process. The wear tests were
High-throughput screening is one of the most extensively used methods for the identification of molecules of interest during early stages of drug development projects. It is however subject to many artifacts due to various mechanisms. Aggregation and redox cycling are examples of mechanisms of unspecific inhibition that make a large number of compounds appear as active in several high throughput s
Even though protonemal development of bryophytes has been well studied, it remains unknown whether interspecific competition among mosses species affects their early growth and development. This study evaluated the effects of interspecific competition on in vitro germination and gametophyte development between each pair-wise combination from six common moss species: Atrichum undulatum, Bryum argen
Antalet användare av sociala medier ökar ständigt och dessa blir en del av allt fler individers vardag (IIS, 2015). I takt med detta blir även debatten om hur unga påverkas av denna synlighet och hur de hanterar den uppmärksamhet de ställs inför på sociala medier allt mer aktuell. Sociala medier är inte enbart verktyg för oss att kommunicera med andra, utan även verktyg för oss att forma jaget. De
There has been an increasing interest in wastewater treatment in last decades to reduce human footprint. Primarily, anaerobic technology focused on treatment and stabilization of sludge, but now the tendency is to give it a major role in low cost treatment of high/low strength wastewaters, since anaerobic digestion offers energy generation through gas production. Anaerobic membrane bioreactors (A
The six participants, two in Sweden and four in Denmark, interviewed for this thesis are all organizational outsiders: they consult organizations on how to create diverse workplaces. The empirical, qualitative material is analyzed within an interdisciplinary framework consisting of feminist, queer, anti-racist, affect and critical diversity theories. The focus of the thesis concerns resistance fro
