När föremål blir tillräckligt små börjar de bete sig annorlunda från hur de vanligtvis beter sig. Effekter, som att föremål kan vara på flera ställen samtidigt eller vara osynligt sammankopplade över stora avstånd, börjar istället att ske. Inom fysiken brukar dessa effekter beskrivas av kvantmekanik, en teori som har varit väldigt framgångsrik med att förklara vår värld. En annan effekt som dyker In this thesis, an experimental scheme to probe deformations to Heisenberg's uncertainty relation between position and momentum for an object of mass similar to the Planck mass is designed. This will allow experimental bounds to be put on deformation parameters for three different models proposed to explain quantum gravity. The scheme is based on existing ideas to couple a micron-sized harmoni

Fracture-mechanics-based avalanche failure modeling offers a promising approach for predicting slope-specific snow stability, as opposed to broader regional avalanche danger levels. Understanding slab avalanche failure through weak layer collapse, governed by both material strength and toughness, is rooted in the coupled criterion proposed by Leguillion. This thesis implements a novel algorithm to

Through the tight link between plants and their pollinators, plant species often decline when their pollinators decline and vice versa. These nominal declines are well studied for many plant-pollinator networks. Less well known is the effect that the decline of a plant species has on the behaviour of its pollinators, and how potential changes in pollinator behaviour affect the reproductive success

Kan vi rädda bina (och långhorningarna) i skogen? Det första du tänker på när du hör ”skogslandskap” kanske inte är pollinatörer? Pollinatörer bidrar dock med viktiga funktioner och ekosystemtjänster i skogen. Bin och långhorningar pollinerar växter när de samlar pollen och nektar. Långhorningar bryter även ner ved. Dagens skogsbruk resulterar dock sällan i tillräckliga livsmiljöer för bin och låLand-use change is one of the main drivers of pollinator declines. However, studies on land-use changes in forest landscapes and their effects on pollinators are underrepresented. Canopy openings with flowering resources and old-growth forest structures can provide sufficient habitats for pollinating insects such as bees (Apiformes) and longhorn beetles (Cerambycidae). However, managed forests are

In this study, the lanthanide complexes Sm(HMDS)2 (1), Yb(HMDS)2 (2), Sm(Cp*)2 (3), and Yb(Cp*)2 (4) were synthesized, and a new polymorph of 2 was identified via single- crystal X-ray diffraction (sc-XRD). Additionally, the previously unreported Yb(III) compound [YbI2(OPPh3)4]I was discovered as a probable disproportionation product of YbI2(OPPh3)4 and characterized via 31P{1H} NMR spectroscopy a

The chemical industry is particularly resource-intensive, consuming a substantial portion of petroleum resources and significantly contributing to greenhouse gas emissions. Consequently, there is an urgent need to explore sustainable alternatives. Biomass has emerged as a promising renewable resource. The dehydration of biomass-derived carbohydrates has proven to be an effective method, producing

Med 2024 officiellt uppmätt som det varmaste året hitills är klimatförändringarna och behovet av att minska utsläppen är mer aktuella än någonsin. Sveriges viktigaste uppgift i denna utmaning är att effektivt elektrifiera sina två största källor till koldioxidutsläpp: industrin och transportsektorn. Dessa två sektorer står tillsammans för hela 65 % av landets utsläpp. Elektrifieringen förväntas leThere is an urgent need to reduce CO2 emissions in Sweden, primarily caused by industry and the transport sector, which together accounted for nearly 65% of the country's total CO2 emissions in 2023. A key solution to this challenge is the rapid and effective implementation of green electrification, which involves transitioning industry and transportation to electricity and electricity-based f

Denna studie syftar till att undersöka sambandet mellan könsmångfald i styrelsen och utdelningsnivåer, med hjälp av data från 70 icke-finansiella börsnoterade företag i Danmark, Finland och Sverige mellan 2014 och 2023. Studien använder en dynamisk fixed effects-regressionsmodell med ett till två års släpande effekter. Data om styrelsesammansättning samt företagsspecifika variabler för 70 icke-finThis study aims to investigate the relationship between board gender diversity and dividend payouts, using data from 70 non-financial companies in Denmark, Finland and Sweden from 2014 to 2023. Using a dynamic fixed effects regression model with one and two lags, we analyze whether board gender diversity significantly affects dividend payout. We collect board- and firm-specific data from Eikon for

Statistik visar att diskriminering på arbetsplatser och på arbetsmarknaden är ett vanligt förekommande fenomen. HR-yrket präglas av låg representation av personer födda utanför Norden och är dessutom starkt kvinnodominerat. Syftet med denna uppsats är att undersöka hur HR-professionella med etnisk minoritetsstatus, i kombination med andra identitetsaspekter, upplever och hanterar utmaningar i sitt

Prefabricated buildings were popularized in Eastern Europe due to a high demand for new housing after the World War II. They were based on the principles of modernism and are characterized by their large scale and being made of manufactured, concrete elements. In addition, the buildings were deprived of artistic elements, altogether resulting in them being monotonous and repetitive. They are locat

This project was completed in collaboration with the graph database company Neo4j with the aim of developing a new algorithm for automatic detection of software bugs that degrade system performance, commonly referred to as performance regressions in the industry. Due to the large number of benchmarks used to monitor different aspects of the product environment, a flexible and robust solution was n

Digitization has not only changed the way societies store and share information, but also the view of media. With increasingly portable and accessible technologies, the conditions for the production and distribution of media are changing. The digital has been interpreted in many ways, both as a loss and as something new. A recurring question is what visibility and freedom the digital gives individ

This thesis examines the behavior of a single-qubit quantum system controlled by feedback. Key parameters such as coupling strength, dissipation, and detuning are explored to improve quantum coherence and stability. Based on the results, practical methods for controlling quantum systems are proposed to better understand quantum control techniques and then improve the performance and stability of q

Detta är en komparativ översättningsundersökning som tar sin utgångspunkt i den engelska vetenskapliga texten "From Etic to Emic Units in the Structural Study of Folktales" av Alan Dundes och dess svenska översättning av uppsatsförfattaren. Syftet är att undersöka skillnaden i ordantal mellan de två språken. Först analyseras den engelska källtexten enligt Hellspong & Ledins (1997) anThis is a comparative translation study based around the English scientific text "From Etic to Emic Units in the Structural Study of Folktales" by Alan Dundes, as well as its Swedish translation by the study author. The aim of the study is to compare the differences in word count between the two languages. First, the English source text is analyzed with the model presented by Hellspong &

This thesis explores the design and prototyping of a common platform for controlling Power over Ethernet (PoE) based peripheral devices. The new IEEE 802.3bt standard, which allows for higher power delivery (90W) over Ethernet cables, is investigated for its potential to power and control various devices such as LED lighting. The study aims to design a common software platform for PoE-powered devi

This bachelor thesis explores the intersection of Christian identity and postmodern critique through the concept of profilicity and related concepts. By examining the perspectives of theologians and philosophers, particularly with the help of the works of Medi Ann Volpe and her sources and synthesizing them with the works of Hans-Georg Moeller and Paul J. D’Ambrosio and their sources, various conc
