Linné glacier has retreated approximately 1.8 km since 1936 and 1 km between 1995 and 2019. Linné glacier is following the same trend as other glaciers around Svalbard. Linné glacier is a well-monitored glacier with a time series of air temperature, incoming solar radiation and snow height data since 2003. Annual recordings of the glacier margin from 2007, allows for an accurate reconstruction of

Finite-volume corrections to the Lattice Quantum Chromo Dynamics (LQCD) calculation of the hadronic vacuum polarization are here considered to one loop, for the simplified case of one and two propagators of equal mass. Simplifications in the calculations are sought for by comparing computations in momentum space, time-momentum space and position space. The derivation of the finite-volume correctio

Archaeobotany and GIS are closely linked with archaeology, it is hard to imagine a modern archaeological investigation without them. The two appear to complement each other. GIS links highly complex sets of data with space, and offers a range of analytical tools. Archaeobotanists look for patterns in data over time and space to interpret human behaviour. Yet GIS is underused in archaeobotany. Ther

The sustainability benefits of car sharing have attracted many city governments. The Seoul Metropolitan Government introduced a car sharing (CS) scheme in 2013 and has been hailed as a pioneer metropolitan city in terms of CS diffusion. However, there was limited understanding of how CS advocates engaged in institutionalizing CS in Seoul. Addressing this, the aim of this study is to describe key s

In this thesis, Twitter data is used to predict the intraday stock return for Tesla, Inc. We present two different methods to extract the tweets’ sentiment: A dictionary-based approach (VADER) and a machine learning approach (SVM). Additionally, we control for other dimensions as the user and discussion dimension. Then a Granger causality test and a lasso regression are conducted on a one- and fiv

Sverige har över tid mött kritik för långa häktningstider och omfattande användning av restriktioner, främst isolering. Uppsatsens syfte är att undersöka vad det är som gör att just Sverige sticker ut jämfört med våra grannländer. För att uppfylla uppsatsen syfte har gällande rätt sammanställts för de tre länderna, Sverige, Danmark och Norge, med hjälp av den rättsdogmatiska metoden. Dessa har seSweden has over time faced criticism for its use of restrictions, such as isolation, for remand prisoners and also the long times that suspects are being held awaiting trial. The purpose of this paper is to investigate what makes the Swedish justice system stand out when compared to fellow Nordic countries. To fullfil the purpose of this paper Sweden’s, Norway’s and Denmark’s legislations have b

Current methods for analysing cellular content require lysing the cells. This can be a drawback when there is a desire to study dynamic processes in the cell as the cells die during the lysis process, and a study over time is not possible. One such example exist inthe field of molecular biology, where diabetes researchers desire to study the insulin geneexpression of beta cells over time, and its d

I en värld där koldioxidutsläppen ständigt ökar är solenergi en av de mest lovande möjligheterna till omställning. Solceller använder sig av kemiska föreningar som till följd av absorption av UV- och synligt ljus kan överföra elektroner till sina grannmolekyler. Elektronöverföringen sker genom att molekylen exciteras till ett så kallat laddningsöverföringstillstånd (CT-tillstånd, från engelskans cMolecular properties of spin crossover complexes [Fe(CN)6]4-, [Fe(CN)6]3-, [Co(CN)6]3- and [Co(CN)6]2- were computed using quantum chemical computations at Density Functional Theory (DFT) level of theory to examine how nuclear charge, oxidation state and electron configuration influence energy levels of MC and CT states of the compounds. Across the series, the MC states of the compounds were found

The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. In connection to the inlet lies an elongating sand spit which causes erosion and destruction of residential areas on one side of the

Föreställ dig att du kunde producera vatten från luft, eller ha arean av en fotbollsplan i ett gram pulver. Det är två utav många fenomen som syntetiska metall-organiska ramverk (MOF) kan åstadkomma eftersom de ofta besitter kristallporer i storlek av nanometrar. Denna studie fokuserar på att kapsla in katalysatorer i MOF:ars porer. Sådana ramverk kan kallas catalyst@MOF och syftet är att lätt kunMetal-organic frameworks (MOF) are hybrid organic-inorganic porous materials with a crystalline framework. The MOF frameworks contain specific nano-sized pores that can be used for gas storage, gas separation, drug storage, luminescence sensoring, artificial photosynthesis, drug delivery, catalysis etc. The aim of this study was to encapsulate three diiron hexacarbonyl and one Ni(II) catalysts in

Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int

Vi har i vår studie undersökt hur chefer talar om och beskriver motivation i arbetssammanhang. Vi har även studerat hur den egna förståelsen av motivation återspeglas i hur chefer resonerar kring och arbetar med andras motivation. Våra forskningsfrågor var följande: Hur reflekterar och talar chefer kring motivation i arbetssammanhang? och Har den egna uppfattningen av motivation någon betydelse el

The low-carbon benefits and emissions savings from circular economy (CE) strategies are not yet well understood, yet are crucial for global development within Planetary Boundaries. Using the mineral fraction of waste incinerator bottom ash (MIBA) as construction material in road construction is one application of a CE strategy that could lead to environmental gains by substituting energy-intensive

This explorative case-study examines the dynamics of operationalizing climate change adaptation (CCA) measures in the aftermath of climate change induced natural disaster at the community level in a low-lying coastal Nation State with fragile institutional capacity. It explores the roles and responsibilities different stakeholder groups take and identifies constraints and facilitators for operatio

This thesis focuses on the case study over the Kävlinge catchment located in the south of Sweden, and mainly in the Kävlinge river. This river, which is the mainstream of the catchment, has been subject to modifications due to agricultural activities. Such modifications, like straightening or increasing the depth and channeling sections of the river, will affect the river’s hydrodynamics. These in

Denna avhandling beskriver syntes av en fem-koordinerande ligand och järnkomplex av denna nya ligand. Järnkomplexen har syntetiserats med syftet att framställa katalysatorer som kan härma reaktiviteten hos järnoxygenas-enzymer. Denna typ av enzymer katalyserar mängder med viktiga oxidationsreaktioner. För att enzymerna ska kunna utföra dessa essentiella oxidationer har ett högvalent Fe(IV)-oxo intThe pentadentate ligand 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine was isolated and characterized. Mononuclear iron(II) complexes of the ligand have been synthesized and characterized.

The concept of industrial symbiosis (IS) provides practical solutions for resource efficiency and low-carbon development. The IS represents a collective, multi-industrial approach for companies to improve their economic and environmental performance through the sharing of heat, electricity, water, by-products, information, and reuse of waste. The main challenges to IS emergence include a long dura

Dibenzo[a,e]cyclooctatetraene or dbCOT is a commonly used ligand in transition metal catalysis. Moreover, the Strand group has been using its properties to change shape (from tub-shaped to planar and vice versa upon reduction/oxidation) to develop novel molecular machines. However, the use of dbCOT in both transition metal catalysis and as a building block for molecular machines has been limited b

Denna uppsats utreder huruvida det går att identifiera en särskild rättsordning vad gäller fördelningen av internationellt ansvar mellan EU och dess medlemsstater under blandade avtal, det vill säga internationella avtal som undertecknats av EU och vissa eller alla dess medlemsstater på ena sidan, och en tredje stat eller internationell organisation på den andra. Uppsatsen presenterar slutsatsen This thesis examines whether there exists a special legal regime for the apportionment of international responsibility between the EU and its Member States under mixed agreements. The thesis argues that the sui generis aspects of the EU, such as its constitutional order, its international legal personality, its extensive treaty-making powers, legislative powers, its executive federalist construct,
