The demand for biofuels is increasing as a result of increased climate mitigation ambitions aiming to replace the use of fossil fuels. To meet the increasing demand, energy crops grown on agricultural land used to produce biofuels is getting more and more attention. Since agricultural land is a scarce resource, conflicts can arise between food production and biomass for biofuels, making it essenti
Working with innovation has become an essential factor in driving firm success in fast-changing industries like the energy sector. As a result, a considerable amount of previous research has focused on the innovation activities of employees working in R&D or similarly. However, a more recent field of research has focused on studying the employees outside these innovation-specific functions and
Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in
I takt med att hållbarhet blir viktigare söker många företag inom jordbrukssektorn lösningar för att fasa ut fossila drivmedel. Utmaningen blir ännu mer komplex när ersättningen ska vara kompatibel med en existerande fordonsflotta, utan investering i nya fordon. Denna studie jämförde fyra kommersiellt tillgängliga och förnybara drivmedel med referensbränslet diesel. De undersökta drivmedlen är HVAs sustainability becomes more important in today's society, many companies in the agricultural sector are looking for new alternatives to fossil fuels. The challenge becomes even more complex when the replacement must be compatible with an existing vehicle fleet, without requiring new investments in vehicles. This report compares four commercially available and renewable fuels, using convent
This thesis investigates the climate impact of a newly constructed residential complex in Oceanhamnen, Helsingborg, through an extended life cycle assessment (LCA) covering both building and non-building elements such as road infrastructure, inner courtyards, external installations, that area often overlooked in conventional assessments. The aim is to develop a replicable method to quantify the gl
Vitamin A deficiency affects approximately 30% of children under 5 years old globally, with Bolivia showing persistent rates despite intervention efforts. High-altitude environments like La Paz present unique challenges for nutrient-rich crop production, mostly due to harsh growing conditions and limited infrastructure. This study investigated wether targeted modifications of hydroponic substrates
The purpose of this study is to investigate the factors determining continuous user-engagement for the elements Avanza Svajper and Milstolpar. By analyzing qualitative insights from both users and Avanza representatives, and interpreting the findings through the lenses of Self-Determination Theory, the Octalysis Framework, and the MDA Framework, this study provides a deeper understanding of the st
This study investigated how acoustical challenges, specifically changes in signal-to-noise ratio (SNR), affect the neural tracking of attended and ignored speech in individuals with hearing impairment. The analysis began with the speech envelope and was progressively extended by incorporating phonetic information as well as outputs from all layers of OpenAI’s Whisper model. The goal was to gain a
Background: Regional myocardial function is typically evaluated by visual assessment by experienced users, or by methods requiring substantial post processing time. Visual assessment is subjective and not quantitative. Therefore, the purpose of this study is to develop and validate a simple method to derive quantitative measures of regional wall function from velocity encoded Cardiovascular Magnet
Chronic hyperglycemia leads to pancreatic beta-cell dysfunction characterized by diminished glucose-stimulated insulin secretion (GSIS), but the precise cellular processes involved are largely unknown. Here we show that pancreatic beta-cells chronically exposed to a high glucose level displayed substantially increased amounts of stress fibers compared with beta-cells cultured at a low glucose leve
Context: Postprandial glucose homeostasis is regulated through the secretion of glucagon-like peptide 1 (GLP-1) through stimulation of insulin secretion and inhibition of glucagon secretion. However, how these processes dynamically adapt to demands created by caloric challenges achieved during daily life is not known. Objective: To explore adaptation of incretin and islet hormones after mixed meal
The reliable detection of neutrons in a harsh gamma-ray environment is an important aspect of establishing non-destructive methods for the characterization of spent nuclear fuel. In this study, we present results from extended in-situ monitoring of detector systems consisting of commercially available components: EJ-426, a 6Li-enriched solid-state scintillator material sensitive to thermal neutron
Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. Understanding the residual stress imparted by machining is an essential aspect of understanding the machining process and overall part quality. Although many investig
Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution
The main objective was to develop a wipe sampling test to measure surface contamination of the most frequently used antineoplastic drugs (ADs) in Swedish healthcare and, furthermore, to develop an analysis method sensitive enough to assess low levels of contamination. Two wipe sampling tests with separate sample processing methods assessing (i) cyclophosphamide (CP), ifosfamide (IF), 5-fluorouraci
Of increasing interest in the field of protein modelling and simulation is the effects of crowding. In a living cell, large molecules can take up 30% of the cell plasma volume, and affects the folding and dynamics of proteins. Computer simulations have so far focused mainly on simple spherical crowders, but recent simulations with protein crowders have shown effects beyond what can be replicated u
Social work with quality? Public Comparisons as show-window and tool Auditing, evaluations, rankings and performance measurements of the public sector are often presented as tools to ensure accountability, improvement, quality and transparancy in publicly funded organizations. One such tool is called "Public Comparisons" (Öppna jämförelser), a Swedish publicly reported measurement of qu
Vad studenter väljer att studera på universitetet påverkas av många olika variabler. Syftet med studien var således att undersöka hur individers olika bakgrundsfaktorer samt personlighetsdrag utifrån Big-five-teorin påverkar deras val av utbildning. Studien undersökte relationen mellan socioekonomisk status, personlighetsegenskaper, kön samt etnicitet och studerades på studenter vid Lunds universiWhat students choose to study is effected by different variables. Thus, the aim of this study is to examine how different background variables and personality traits from the Big-five theory influence students choice of higher education. The study exam-ined the relation between socioeconomic status, personality traits, gender and ethnici-ty and their choice of study was observed on students from L
Aims: To determine the underlying cellular changes and clinical correlates associated with pathology of the hypothalamus in amyotrophic lateral sclerosis (ALS), as hypothalamic atrophy occurs in the preclinical phase of the disease. Methods: The hypothalamus was pathologically examined in nine patients with amyotrophic lateral sclerosis in comparison to eight healthy control subjects. The severity
