Silicon (Si) is an essential macronutrient for diatoms, an important component of lacustrine primary productivity that represents a link between the carbon and silicon cycles. Reconstructions of lake silicon cycling thus provide an underexploited window onto lake and catchment biogeochemistry. Silicon isotope geochemistry has potential to provide these reconstructions, given the competing source a
Background: This study investigates gaze behaviour in child dialogues. In earlier studies the authors have investigated the use of requests for clarification and responses in order to study the co-creation of understanding in a referential communication task. By adding eye tracking, this line of research is now expanded to include non-verbal contributions in conversation. Aims: To investigate
The European Union (EU) has laid down very clear objectives for the reduction of greenhouse gases in the hope that it will prevent or mitigate climate change. Political incentives are used to make the power industry adopt changes in order to reach these EU targets. In this thesis, some solutions that could help power companies meet the EU objectives are evaluated. Thermodynamic models have been de
Förutsägande om klimatförändringar och nederbördsmönster i den närmaste framtiden samt urbanisering leder till högre volymer av avrinning, vilket i sin tur utmanar hållbarheten och funktionaliteten hos stadsdräneringsnät. För att förstå hur dessa förändringar kommer att påverka den befintliga infrastrukturen i stadsområden behövs integrerad programvara för urban vattenmodell för att identifiera efThe predictions on climate change and precipitation patterns in the near future, as well as urbanization, lead to higher volumes of runoff, which in turn challenge the sustainability and functionality of urban drainage pipe networks. In order to understand how these changes will affect the existing infrastructure in urban areas, integrated urban water model software are needed to identify effectiv
Title: Swedish Private Equity - A Reliable Source for IPO Pricing? Seminar date: 03/05/2020 Course: FEKH89, Bachelor Degree Project in Financial Management Undergraduate Level, 15 credits Authors: Johan Brown, Patrik Nilsson, Filip Wallersköld Supervisor: Anamaria Cociorva Key words: Underpricing, Information Asymmetry, Private Equity, IPO, Sweden Purpose: To explore if and why Private Equit
Avskiljning, transport och lagring av koldioxid (CCS) är en intressant teknologi med förmågan att minska klimatpåverkande utsläpp inom industrisektorn. Denna teknik framhävs regelbundet på både internationell och nationell nivå som ett nyckelbidrag i kampen mot klimatförändringarna, bland annat förespråkas CCS-teknikens nödvändighet av både EU och IPCC. Användningen av CCS har även uppmärksammats Carbon capture and storage (CCS) is an interesting technology with the ability to reduce carbon dioxide emissions within the industry sector. It is constantly highlighted within the international community as a vital tool in the fight against climate change. Some of those who strongly advocate for the use of CCS include the EU and the IPCC. This technology has also been deemed useful by Swedish au
In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio
This 30 credits master degree project focused on creating a product design with the aim to expand Arduino’s maker community to reach young girls. The goal was to design a wearable merchandise for Arduino #include, which would inspire girls to explore STEM and learn about technology and programming. Arduino is a open source hardware company and Arduino #include is an inclusivity programme to celebr
Popular AbstractAvhandlingen presenterar, från ett fenomenologiskt perspektiv, interaktionen mellan naturvetenskapens kunskap och annan kunskap, här kallad "vardagskunskap". Utgångspunkten i presentationen är människans existens. Två aspekter av denna lyfts fram som centrala - att människan är kroppsligt utsatt för, berörd av, något hon inte har full kontroll över, samt att hon alltid agerar utifrThe dissertation presents a phenomenological view on the interaction between science knowledge and prescientific knowledge. Drawing on Husserl, Merleau-Ponty and Lévinas the human bodily grounded existence is described, the central feature of this existence being its responsivity to the Other. This responsivity is presented as the starting point for the production of science knowledge, thus making
For some time, directional antennas have been considered to solve connectivity and interference issues in wireless networks. Several scenarios have been presented and often the conclusions drawn are positive, showing increase in capacity. However, to date there has been no effort to assess a holistic picture of the benefit/cost tradeoff and previous work mainly concerns either link scheduling or a
The 2008–2009 global financial crisis triggered ‘Green Energy Economy’ (GEE) policy packages to stimulate green growth in many countries. China soon became a leader and, supported by its 11th Five-Year Plan (2006–2010), devoted approximately one-third of its US$ 647 billion stimulus package to green energy technologies. Since then, numerous policy instruments have been implemented to encourage ‘Gr
Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. The electrification of construction equipment creates new possibilities to replace previous hydraulic- with ele
A method is presented for estimating the long exposure point spreadfunction (PSF) degradation due to tilt anisoplanatism in alaser-guide-star-based multiconjugate adaptive optics systems fromcontrol loop data. The algorithm is tested in numerical Monte Carlosimulations of the separately driven low-order null-mode system, and isshown to be robust and accurate with less than 10 relative error inboth
This thesis has contributed to the methodological development in the field of assistive technology and has generated new knowledge about the effectiveness and the service delivery process when powered mobility devices are provided to adult first time users in a Nordic context. Some of the results have been used to investigate the relationship between the three key elements of Donabedian’s conceptu
The cysteine proteases are enzymes found in every kingdom of life. Clan CA is the largest of the cysteine protease clans, with members all displaying a Cys/His/Asn(Asp) catalytic triad responsible for hydrolysing the peptide bond within the substrate. To regulate the activity of the proteases, another group of proteins act as natural inhibitors (cysteine protease inhibitors) and bind to the protea
Popular Abstract in Swedish Avhandlingen består av fyra uppsatser som handlar om individers hälsorelaterade beteende och investeringar i högre utbildning. Tre av uppsatserna fokuserar på olika aspekter av läkemedelsanvändning och syftar till att förklara varför individer med liknande medicinska behov är olika benägna att använda receptbelagda läkemedel. Den fjärde uppsatsen studerar hälsans betydeThis thesis consists of four essays on individual health behaviour and investment in higher education. Three of them consider different aspects of pharmaceutical utilization and aim at explaining some of the observed individual variation in access and adherence to treatment regimens. The fourth explores the potential link from health in young adulthood to subsequent university education. The firs
In 2013, the Large Hadron Collider provided proton-lead and lead-proton collisions at the center-of-mass energy per nucleon pair root s(NN) = 5.02 TeV. Van der Meer scans were performed for both configurations of colliding beams, and the cross section was measured for two reference processes, based on particle detection by the T0 and V0 detectors, with pseudo-rapidity coverage 4.6 < eta < 4.9, -3.
The mutational mechanism underlying the striking diversity in MHC (major histocompatibility complex) genes in vertebrates is still controversial. In order to evaluate the role of inter- and intragenic recombination in MHC gene diversification, we examined patterns of nucleotide polymorphism across an exon/intron boundary in a sample of 31 MHC class IIB sequences of three-spined stickleback (Gaster
