Med hjälp av laserljus i en kubisk kammare har halten CO2 runt en katalysator studerats. Denna typen av studier är viktiga för att kunna förbättra och effektivisera katalysatorer vilket är väldigt viktigt inom både industri och för miljömål. Använder man laser på det här sättet kan man se hur olika parametrar, så som flöde eller tryck, påverkar effektiviteten av katalysatorn. Andra metoder har intCO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. Some results have been visualised by images showing concentration, given by the PLIF signal, of CO2 inside the

Research on aid is continuously exploring new channels to measure its effectiveness on economic development. The Millennium Development Goals have set the standard for aid policy-making and now, when facing deadline, its partakers have to set a new aid policy-agenda. The European Union is the largest donor of official development assistance (ODA), contributing a total of 50-60 percent of world ODA

sustainability, stakeholder theory, general theory on collaboration as well as identified success factors in the literature are presented. Empirical foundation: The empirical data consists mainly of the responses from 19 interviewees representing 15 different organizations in New York City. Conclusions: The results from this study are an expanded and redesigned framework based on the empirical fin

Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity (SAA) was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. The developed method was found to be

Behandlingsmetoder för medialt tibialt stressyndrom; en litteraturstudie. Bakgrund: Medialt tibialt stressyndrom är en av de vanligaste överbelastningsskadorna bland idrottsmän. Symtomet ses främst bland kvinnor, och grupper med hög prevalens är militärer, löpare och dansare (mellan 4 % och 35 % drabbas). Genom tidigare studier har forskare trott att symtomet beror på en inflammatorisk process i

Young people account for 40% of all new adult infections worldwide. If education can have preventive effects, great opportunities arise considering this demographic structure of the epidemic since young people are dominating educational enrollment. This thesis investigates the impact of education on HIV prevalence. For empirical testing, five multivariate regression models with ordinary least squa

Since 1910, the major income of Venezuela comes, from the oil exploitation industry which is connected to the consolidation of the nation-state. This oil wealth has throughout history influenced its relations with countries in the Americas, United States and the rest of the world. This case-study examines Venezuela as a petro-state and its impacts on Latin American post-liberal regionalism and po

This theory testing study investigates the decision-making of the member states in the Dispute Settlement Body of the WTO, using a game theoretical approach. Game theory has its origins in political philosophy and can thus be valuable when analysing the behaviour of states in international regimes. Through using the specific game theory model Stag Hunt, this study aims to examine if such a model c

This study examines the political discourse concerning access to subsidized health-care for irregular immigrants in Sweden. The discourse is the public one fetched from the two major parliamentary debates that have taken place, one in 2008 and one in 2013. The parliamentary material is studied by way of a critical discourse analysis in which the material is related to two ideologically separate pr

The objective of this essay is to investigate if the performance of an Exchange-Traded Fund (ETF) share has an impact on the probability of closure of the same Exchange-Traded Fund. A great number of ETFs closures occurred in the last two years and the number of these closed ETFs represent a relevant percentage of the total number of ETFs that have been liquidated since this type of shares came to

Stress fractures are problematic type of fractures as they are prone to delayed and nonunions. In order to achieve healing and restore the bones mechanical aspects, invasive treatments such as attaching plates, nails and screws are sometimes needed to stabilize the bone and facilitate healing. These surgical treatments often cause discomfort and pain to the patient. Therefore different options nee

This paper examines the relationship between Big Data and two financial assets. This is achieved through replication of the portfolio method proposed by Preis, Moat and Stanley (2013) which examines and tests the relationship between search engine query volumes and financial markets. Collecting data from 98 different search terms, this paper extends the study by applying the strategy to two new fi

It is not illegal for an undertaking to have dominant position under EU competition law but such undertakings have a special responsibility to ensure that its conduct does not distort competition. Margins squeeze is one of the many different measures that can be construed as an abuse of an undertakings dominant position under Article 102 TFEU. Margin squeeze can be implemented by a vertically-inte

When carton packages are formed in a filling machine, there have to be a certain tension in the material package to keep it stretched, however not so much that the material is damaged. In the Tetra Pak A1 filling machine this is achieved through a \emph{web tension-mechanism} consisting of a number of rollers and a pneumatic cylinder. The aim of the master thesis is to get a simulation model for

A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. This so-called "massive MIMO" promises attractive gains in spectral efficiency with

Self-rated health (SRH) is an internationally known concept in epidemiological research. It is considered as an efficacious way of determining the overall health of individuals and population. While the association between self-rated health and mortality has been well documented, since SRH also encompasses a subjective element where attitudes, perceptions and psychosocial factors are active more r

The ‘policy window hypothesis’ in the context of extreme climate events, refers to a phenomenon whereby adaptation action is facilitated and occurs directly in response to extreme climate events. Despite the intuitive logic that extreme climate events may provide useful opportunities to design and implement successful adaptation policies, the literature suggests that this is not the case. With thi

Spridningsmöjligheterna för fyra arter av hotade eller sårbara trädlevande skalbaggar i Lunds stad är bristfälliga. För att bibehållandet av livskraftiga populationer är det av stor vikt att individerna har möjlighet att sprida sig mellan de livsmiljöer som träden utgör. Därför ökar betydelsen av ett bevarandearbete som integreras med stadens samhälleliga planering så att befintliga träd som är väUrban trees are of great value as habitat and as elements for dispersal of many biological organisms. Hence, tree inventories are an important step for local municipalities in the effort to promote urban biodiversity of organisms dependent of trees for dispersal and survival. Lund is one of the municipalities which have carried out a comprehensive tree inventory. The purpose of this study is, on b

The ray tracing algorithm has long been used to create near photorealistic images and even simple ray tracers can simulate effects such as shadows, reflections and refractions where other methods struggle. Today, the state-of-the-art CPU ray tracers are typically those that are able to efficiently leverage datalevel parallelism at the instruction level by using SIMD extensions to allow the process
