Rotary vacuum filters (RVFs) with adiatomaceous earth (kieselguhr) coatings as filter aid are the most established technology for the removal of the so-called mud fraction after liquefaction and saccharification in the production of starch-based sweeteners. The RVFs is an open process which is further associated with the use of filters resulting in an increasing disposal challenge. Based on this t
Perovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling. Scientists all over the world are working towards solutions and
Scientific abstract: The study set out to investigate diurnal patterns in methane flux in a fen in Kobbefjord, Southwest Greenland and to link these to physical and biological parameters in the environment. Methane flux was measured using six chambers which recorded the flux every ten minutes from spring to autumn. Methane flux data from 2009 and 2010 were compared to photosynthetically active radA study of diurnal variations in methane flux in a fen in Kobbefjord in Southwest Greenland is presented. Four separate periods, each of one week, from the growing seasons of 2009 and 2010 were chosen. Methane flux data were compared to surface temperature, soil temperature and photosynthetically active radiation (PAR). Regression tests between surface temperature and methane flux produced highly
Studien koncentrerades på den ökade uppmärksamheten kring pokerspel i media. Intresset tycks ha ökat kring detta "fenomen" vilket fört med sig både kommersiell uppmärksamhet och kanske en ökad nyfikenhet för dem som tidigare inte varit spelintresserade. Föreliggande analys diskuterade varför ett sådant intresse plötsligt fått genomslagskraft. Diskussionen inleddes med ett teoriavsnitt dä
Improved management of agricultural soils to sequester carbon from the atmosphere is considered an important climate mitigation measure. Intensive agriculture often leads to degradation of soil organic carbon (SOC), contributing to climate change and loss of soil ecosystem services. Interventions in agricultural management can halt or reverse the loss of SOC. Annual SOC change rates for interventi
The start-up company LEVTEK is launching a new ultralight electric utility vehicle called the LEVKART. The Levkart uses a combination of robotics and AI-technology to offer semi-autonomous or autonomous riding and usage. The purpose of the vehicle is to serve as an alternative to cargo bikes and electric scooters designed for easy usage and as a more sustainable option to fossil-based transport. T
The expected increase in both consumption and production of electricity strains the Swedish electricity grid, necessitating both reinforcement and expansion. Concurrently, the need to decarbonise heavy industry is becoming more urgent to achieve the EU Climate neutrality goal by 2050, with hydrogen anticipated as a key player. Hybrid energy systems that combine the generation of renewable electric
The aim of this thesis is to examine the role of early life environments for a variety of individual-level health and socioeconomic outcomes in contemporary Sweden. Ever-expanding human lifespans have contributed to the emergence of novel socio-health phenomena confronting contemporary Swedish society. A new research framework has emerged in the last 30 years suggesting that individuals’ ability t
This thesis examines brand activism's role in promoting social change through contributing to democratic debates by analyzing Oatly’s environmental brand activist campaigns in a polarized context: the United States. Therefore, the research questions chosen for this thesis examine, firstly, how Oatly discursively constructs their environmental brand activism in the United States; secondly, whet
The coast is an ever-changing environment, and due to climate change, coastal research is becoming more challenging. To detect changes in the coastline, such as erosion, researchers need large amounts of data over long periods of time. Part of the solution could be the citizen science project CoastSnap – a global community beach monitoring program. The aim of this study was to examine factors that
In a new episode of the podcast Ceteris Never Paribus, the host Maria Bach speaks to Evelina Kallträsk, David Larsson Heidenblad, Anna Nilsson Hammar and Johan Östling, all members of the Lund Centre for the History of Knowledge (LUCK). They discuss what is the history of knowledge and how its approaches might be useful for historians of economics.
Recent droughts from 2017 to 2020 induced significant stress on woodland canopies across eastern Australia, resulting in widespread tree browning and mortality. However, the trajectory of post-drought recovery remains unclear, with uncertainty about whether canopy conditions are improving or continuing to decline. Identifying the key local environmental and climatic factors influencing drought-ind
COVID-19 vaccine hesitancy poses a threat to the success of vaccination programmes currently being implemented. Concerns regarding vaccine effectiveness and vaccine-related adverse events are potential barriers to vaccination; however, it remains unclear whether tailored messaging and vaccination programmes can influence uptake. Understanding the preferences of key groups, including students, coul
The building sector, as a major consumer of energy and resources, has been slow to adopt sustainability and digitalization compared to other sectors. This dissertation investigates how digital tools, particularly computational design (CD), can support the reuse of building parts within a circular economy framework, through design for disassembly and reuse-centred design (RCD) strategies. The resea
Storm surges combine the power of two natural hazards, strong winds and flooding, and can have devastating effects on people, infrastructure, and nature in coastal areas. Ongoing global changes, including rising sea levels and shifting storm patterns, are expected to increase both the frequency and amplitude of such events in the future. There are, however, significant regional variations and someStorm surges combine the power of two natural hazards, strong winds and flooding, and can have devastating effects on people, infrastructure, and nature in coastal areas.

Atrial fibrillation (AF) is a prevalent and morbid abnormality of the heart rhythm with a strong genetic component. Here, we meta-analyzed genome and exome sequencing data from 36 studies that included 52,416 AF cases and 277,762 controls. In burden tests of rare coding variation, we identified novel associations between AF and the genes MYBPC3, LMNA, PKP2, FAM189A2 and KDM5B. We further identifie
This essay investigates the need for prioritizing resilience and mindfulness in academia and elaborated on a pragmatic approach to how we as scholars can improve our well-being collectively in today’s demanding academic environment.
Prediktionen av aktieprisutvecklingen har alltid legat i intresse för den finansiella marknadens aktörer. Flera studier har frambringat värdefulla prediktorer för aktieprisutvecklingen. Som en relativt ny prediktor av aktieprisutvecklingen har varians riskpremium rönt uppmärksamhet i forskningsvärlden. Varians riskpremium har i studier visat sig vara träffsäkrare i prognostiseringen av aktieprisut
