In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. Planar Lase
Recent global warming trends, particularly in the arctic regions and Himalayas are modifying forest structure and function, notably biogeographical changes in tree species distribution together with alteration in Net Primary Production (NPP), Leaf Area Index (LAI) and Carbon biomass. These alterations are most pronounced in mountain environments, carrying significant impacts on woody species which
Titel: Validering av en handledsburen aktivitetsmätare och en självskattningskala för beräkning av VO2max. Bakgrund: Fysisk aktivitet och god aerob kapacitet är kopplat till god hälsa och lägre risk för livsstilsrelaterade sjukdomar. I dagsläget anses maximalt arbetsprov med ergospirometri och gasanalys för bestämning av VO2max (VO2max-test) vara det mest exakta sättet att mäta aerob kapacitet. Su
Bakgrund: Obesitas och psykisk ohälsa tillhör de största globala hälsoutmaningarna i modern tid och har under de senaste decennierna varit ett växande problem. Människor har fått en mer stillasittande livsstil och större tillgång på kaloririk föda. Faktorerna som påverkar prevalensen är många men att det behöver ske en förändring är säkert. Syfte och frågeställningar: Syftet var att kartlägga BMI,
The transition from animal-based to plant-based proteins is rapidly increasing because of different concerns about meat consumption, some being the nutritional and environmental effects of meat consumption. During this transition, there needs to be a holistic approach to assessing plant-based food. This master thesis is focused on investigating the nutritional and environmental impact of three pla
This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes
Heterologous overexpression of proteins signifies that the encoding gene of a protein in one organism is expressed in another host organism that normally does not have that gene in its genome. In basic biochemical research, this is an important method for studying various protein functions such as activity and interactions in biological processes, as well as obtaining sufficient amounts to determi
Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. The central theme of this study is to understand the dependencies of this SIP mechanism and improve its existing numerical
Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). Currently, the European net land carbon sink is decreasing largely due to forest ageing (Pilli et al., 2022),
Background The two main functional goals of postural control are postural stability (balance) and postural orientation. Postural orientation is the ability to maintain alignment between body segments and the environment during a static or dynamic activity. Nae et al. have evaluated the measurement properties of a clinical test battery for assessing postural orientation errors (POEs) in patients wi
Background: The global plant-based food shift puts high pressure on manufacturing capacity at facilities like Oatly's Landskrona site. This environment faces high combinatorial complexity due to growing product variety and sequence-dependent cleaning requirements. Relying on manual, experience-based planning to navigate these rules limits throughput and introduces organisational risk. Purpose
Biodiversity hotspots are biogeographic regions exceptionally rich in endemic species showing high rates of habitat loss, making them the priority of global conservation efforts. As part of the biodiversity hotspot with the highest density of endemic species, the West Usambara Mountains in Tanzania require an efficient and resourceful monitoring solution. This thesis aimed to model the tree specie
Forest Aboveground biomass (AGB) is an important indicator of forest carbon storage, but long-term, high-resolution, and spatially continuous Aboveground biomass estimation remains challenging. This study produced annual forest Aboveground biomass estimates across mainland Spain and the Balearic Islands from 2000 to 2024 at 30 m resolution by combining Landsat time series, Global Ecosystem Dynamic
Kulturhistoriskt värdefulla byggnader och miljöer utgör en viktig del av samhällets identitet och kulturarv. Genom PBL har kommunerna möjlighet att skydda kulturvärden genom detaljplaner med hjälp av skyddsbestämmelser, rivningsförbud och varsamhetsbestämmelser. Dessa bevarandebestämmelser används för att säkerställa att kulturhistoriskt värdefulla byggnader och miljöer bevaras, värnas och beaktasThis thesis examines how Swedish municipalities apply conservation provisions in detailed development plans and whether these provisions comply with the requirements of the Swedish Planning and Building Act. The study focuses on preservation regulations intended to protect cultural heritage values, including protection provisions, demolition prohibition and caution provisions. It also investigates
BACKGROUND The global prevalence of functional constipation is approximately 12%. It is characterized by infrequent complete spontaneous bowel movements (CSBMs), hard or lumpy stools, straining during defecation, and has a negative impact on quality of life (QoL). The probiotic strain Lactiplantibacillus plantarum (L. plantarum) 299v (Lp299v) has been demonstrated to be efficacious in irritable bo
Background: The COVID-19 pandemic may worsen the mental health of people reporting subjective cognitive decline (SCD) and therefore their clinical prognosis. We aimed to investigate the association between the intensity of SCD and anxious/depressive symptoms during confinement and the underlying mechanisms. Methods: Two hundred fifty cognitively unimpaired participants completed the Hospital Anxie
Background: Benefits of cardiac rehabilitation (CR) programme components on attaining risk factor targets post-myocardial infarction (MI) and their predictive strength relative to patient characteristics remain unclear. We aimed to identify organizational and patient-level predictors of risk factor target attainment at one-year post-MI. Methods: In this observational study data on CR organization
Background: Prostate cancer (PC) survivors may potentially use substances to cope with psychological distress or poorly controlled physical symptoms. Little is known, however, about the long-term risks of alcohol use disorder (AUD) or drug use disorders in men with PC. Methods: A national cohort study was conducted in Sweden of 180-189 men diagnosed with PC between 1998 and 2017 and 1 801 890 age-
