Microswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. coli ) and pullers (e.g C. reinhardtii ). The occurrence of jets, eddies and flocking have been observed in systems of dens pusher suspension. This phenomenon is called active turbulence. Th
Studying 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
This 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
Syftet med den här studien är att undersöka vad en musikstudent lär sig i arbetet inför en examenskonsert samt examenskonsertens syfte i en musikhögskoleutbildning. Studien består av två delstudier där delstudie A behandlar en individuell förberedelseprocess inför en examenskonsert inom komposition och arrangering och där delstudie B undersöker tankarna hos tidigare kompositionsstudenter samt hos The purpose of this study is to investigate what a music student learns in the work prior to a degree concert and the purpose of the degree concert in higher music education. The study consists of two sub-studies, sub-study A treats an individual process of preparation prior to a degree concert in composition and arranging and sub-study B examines the thoughts of former composition students as wel
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 p
