Visste ni att teknologi som används för avgasrening kan användas i framtidens elbilar? I den katalytiska avgasrenaren i bensin- och dieselbilar finns partiklar som driver kemiska reaktioner i avgasflödet som omvandlar föroreningar till ofarliga ämnen utan att själva förbrukas. Det är samma partiklar som också används i bränsleceller, en lovande teknologi för framtidens fordonsdrift. Trots att dessStudying catalysts under such non-equilibrium conditions is a step towards approaching more realistic reaction conditions for working catalysts. Reactivity during phase changes of ultra-thin FeO2 films grown on Pt(111) are studied in situ with Ambient Pressure X-ray Photo Emission Spectroscopy and Quadrupole Mass Spectrometry, while running the CO oxidation reaction at 160°C and 0:6 mbar. These ph

Vatten är en nödvändighet för ett funktionellt samhälle. Grundvatten är, förutom yt- och havsvatten, en av de stora resurser som vi använder för att tillgodose vårt vattenbehov. Globalt varierar världens vattenanvändning och tillgängligheten av dricksvatten, där en stor andel har någon form av problem med att upprätthålla en god vattenstatus med avseende på vattenkvalitet och kvantitet. Även i SveWater is a necessary resource for a sustainable society. Groundwater is one of our supplies for potable water, other than surface- and seawater. Around the world the usage and accessibility of potable water varies, and many in places there are problems with maintaining a good water situation regarding both water quality and quantity. Even in Sweden, the water situation is not ideal. Even though we

Love, witches and magic has attracted the attention of humans since the dawn of time – clearly, during some periods more than others. This essay concentrates on one period of time when such an interest peaked, namely the Augustan era, when a wave of witch representations emerged in Roman literature. By discussing texts written by the famous poets Horace, Vergil and Ovid, alongside the less well-kn

Young adult novels about suicide are questioned pieces of literature. Fears of suicide contagion and the perceived unsuitability of such narratives for adolescents lie at the centre of this conflict, which has resulted in the banning of books and other censorship moves. Suicide in literature has been the focus of relatively scarce previous research, and there is a need for further literary critici

Background: Trust is a main issue in supply chain collaboration. Since the Blockchain technology has received lots of attention, researchers and industries started to ask what the impact of BCT on supply chain collaboration is, and how they can benefit from BCT in supply chain relationships. This research is about exploring the impact of Blockchain technology on trust in supply chain relationships

This master thesis report is an analysis of upstream supply chain of spare parts of an engineering equipment manufacturing company. The report follows a case study approach to come up with a joint replenishment strategy in order to reduce logistics costs and also meet the customer’s demand, by analysing the current logistics cost for the upstream of supply chain where the spare parts are shipped f

For a coating to withstand scratches, and have good abrasion resistance are extra important for some applications. PVC floors for example are often exposed to extensive wear, and it is therefore important to coat it with a coating that can withstand the hard use. One type of UV coating that have good scratch and abrasion resistance is a coating containing urethane acrylate resin. This type of re

Research aim: The thesis aims to research how higher education professionals perceive internal communication as a mean for knowledge-sharing within their workplace, and how it can support organizational learning. Theoretical framework and literature review: The theoretical framework applied, address and discuss the connection between internal communication, organizational learning, single- and do

Internenet och humor är något som historiker sällan undersöker. Detta främst då dessa skapar problem med hur man bör ta sig an dem. Frågor om detta skapar ett avvaktande från professionella historiker vilket i sin tur skapar ett problem då många intressanta frågor väcks om man som historiker verkar på internet. Det går att se en typ av material på internet med en tydlig koppling till både humor ocThis master’s thesis examines the use of History Didactics and Humour in Internet memes. Memes with historical references combined with Barack Obama, former US president and current president Donald Trump were used to narrow down the vast number of memes available. The memes could be put into two groups; memes that created a more political point through the use of History, and those that created H

This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. Latency statistics were then created using the time it took for th

In order to be able to fold packaging material into good looking packages with maintained barrier properties, the material is first provided with folding indications. This process is called creasing and it is carried out by passing the paperboard between two rollers holding tools which create a permanent deformation in the paperboard, according to a predetermined pattern. These tools have looked

When an automatic swing door is used in an entrance, the energy consumption increases. This is because the door cannot detect when the user has passed and therefore, for safety reasons, stands in the open position for too long. To make automatic swing doors more sustainable one needs smarter sensors that can cover a larger area and communicate with the door. In this thesis 11 different concepts of

This paper analyzes the reactions of two forests, located in the same region, to drought conditions that occurred in 2018. Both locations experienced similar conditions including higher temperature and less precipitation than the previous four years. Both experienced drought that would be categorized as moderate according to standard precipitation index calculations and soil moisture values were v

The purpose of this project is to examine if the existence of a credit rating and if the level of credit rating for the acquirer and target influences which financing source is used in cross-border and domestic M&As. The empirical methods used are the probit and GLM logit models. The dependent variables are the binary, payment method, and the fraction of cash. The main explanatory variables ar

Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. The characterization of ultrashort laser pThe human eye can clearly observe movements as fast as around 0.1 seconds long, but how can we observe the movement that is way too fast for the human eye? For example, you can barely read any labels from a really fast moving formula 1 car. However, if we use a camera which can act faster than the human eye, we can capture the images of the moving object. When a camera takes a picture, it records

Studie av aggregeringstendenser hos en homolog serie peptider med NMR-spektroskopi Examensarbetet utvärderar tillämpningen av 1H NMR-spektroskopi med vattenundertryckning vid en första undersökning av aggregeringsbeteende hos fyra närbesläktade läkemedelsmolekyler. Utveckling av peptidläkemedel står inför många svårigheter. För det första är de är relativt nya på marknaden. LäkemedelsutvecklareThe aggregation propensity of four GnRH analogues, namely D-Phe6-GnRH, ozarelix, cetrorelix and degarelix has been studied with 1H NMR spectroscopy in 100 % H2O, while tracking changes in pH. A method was developed to study aggregation propensities by variations in absolute integral values over time and with concentration. The method provided an intuitive visual comparison of the aggregation prope
