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

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.

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

In this thesis we investigate the effect that weak measurement has on a quantum harmonic oscillator. By implementing a measurement process described by density matrices and positive operator valued-measures, we establish a model where the position eigenstates of a quantum harmonic oscillator in an initially pure state, are measured with a specific measurement strength. The results show that by inc

Det är mycket fokus på hållbarhet och målet att uppnå Agenda 2030 inom byggbranschen. Studien ska därför undersöka hur och om detta går att uppnå med hjälp av kravställning vid upphandling enligt LOU. Går det att använda upphandlingar som ett verktyg och hur gör upphandlarna detta? Finns det några utmaningar för de mindre kommunerna och kommunala fastighetsbolagen? Uppsatsens syfte är att undersökThere is a strong focus on sustainability and goal of achieving Agenda 2030 within the construction industry. The study will therefore investigate how and if this can be achieved through the use of requirements in public procurement under the Public Procurement Act (LOU). Can procurement be used as a tool, and how do procurement officers approach this? Are there challenges for smaller municipaliti

This thesis project explores the significance of public spaces in shaping society, culture, and individual identity, emphasizing their role in promoting democratic values and self-realization. Public spaces, such as squares and marketplaces, serve as platforms for social interaction, economic activity, and cultural continuity. The design of these spaces reflects societal values and historical cont

Hummeln-strukturen har varit föremål för geologiska undersökningar under nästan två hundra år. Den udda förekomsten av paleozoiska block och en cirkulär djupanomali i den i övrigt förkastningsdominerade sjön har gett upphov till många teorier. Det var faktiskt inte förrän 2015 som fynd av chockad kvarts kunde bekräfta att den märkliga formen skapades av ett meteoritnedslag. Den här studien är den The Hummeln structure has been subject to geological investigations for nearly two centuries. The odd occurrence of Paleozoic blocks and a circular depth-anomaly in the otherwise fault dominated lake sparked plenty of theories. It was however not until 2015 that findings of shocked quartz could confirm that the structure originat- ed from a hypervelocity impact event. The present study is the firs
