Abstract A radar study was performed to compare flight parameters between sparrowhawks and common buzzards during autumn migration at the Falsterbo peninsula, Sweden. Common buzzards had higher flight altitudes and were more selective for wind, yet their air - and cross-country speeds were lower than those of sparrowhawks. Furthermore, common buzzards had higher glide ratio, but lower airspeed w
Popular science The eddy-covariance (EC) method is one of the most important methods to measure gas and energy fluxes between biosphere and atmosphere at ecosystem level. This method was applied above the floor of a boreal forest in Norunda, central Sweden, at 1.5 m height. The objective was to measure the energy and carbon dioxide (CO2) fluxes from the soil and the understory vegetation to the at
Forests are critical carbon sinks that mitigate anthropogenic carbon dioxide emissions, a primary driver of climate change. However, the impact that forest management methods have on the ecosystem carbon exchange is under debate and the potential carbon sink strength of forests is still uncertain. In this study, annual net ecosystem productivity (NEP) and forest age data from rotation forests (RFs
In this master thesis work, the effect of polarization, at the Base Station (BS) side, on the performance of multi-user Coordinated Multipoint (CoMP) systems is studied. This study was performed using synchronous multi-link measurements that took place at the campus of the faculty of Engineering, LTH, Lund University, Lund, Sweden, where two different BS setups were studied. In the first setup, on
For long, it has been popular to change the appearance of your hair by making it straight or curly. This change can be made more lasting by doing a perming treatment. These treatments were very popular a few decades ago, but the interest is not as big anymore. A perming treatment makes the hair curly or straight by using formulations with strong chemicals, such as reducing and oxidizing agents.
Policy instruments are used to support the introduction and diffusion of renewable energy technologies as the cost of renewable energy is generally higher than fossil-based energy. The commonly used policy instruments for supporting renewable electricity are quota-based system and the price based feed-in system. While quota based systems specify minimum targets for renewable electricity procuremen
Sisal (Agave sisalana) is a climate-resilient crop grown on large-scale farms in semi-arid areas. However, no studies have investigated soil greenhouse gas (GHGs: CO2, N2O and CH4) fluxes from these plantations and how they relate to other land cover types. We examined GHG fluxes (Fs) in a sisal chronosequence at Teita Sisal Estatein southern Kenya. The effects of stand age on Fs were examined usi
Various benthic mapping methods exist but financing and technical capacity limit the choice of technology available to developing states to aid with natural resource management. Therefore, we assessed the efficacy of using a single-beam echosounder (SBES), satellite images (GeoEye-1 and WorldView-2) and different image (pixel-based Maximum Likelihood Classifier (MLC), and an objectbased image anal
Energy intensive industries are one of the fields in which strong increases of energy efficiency and deep decarbonisation strategies are particularly challenging. Although European energy intensive industries have already achieved significant energy and greenhouse gas reductions in the past, much remains to be done to make a significant contribution to achieving European as well as national climat
Purpose: To analyse if patients with diabetic retinopathy (DR) subjected to cataract surgery differ in outcome compared to patients without DR with regard to best-corrected visual acuity (BCVA), deviation from target refraction, intraoperative difficulties and risk of complications. Methods: A register-based study from the Swedish National Cataract Register (NCR) during the years 2015–2017 includi
Imbalances of blood biomarkers are associated with disease, and biomarkers may also vary non-pathologically across population groups. We described variation in concentrations of biomarkers of one-carbon metabolism, vitamin status, inflammation including tryptophan metabolism, and endothelial and renal function among cancer-free older adults. We analyzed 5167 cancer-free controls aged 40–80 years f
According to the Global Burden of Disease study, occupational exposures to particulates, gases and fumes were responsible for 0.36 million deaths and 8.8 million disability-adjusted life years globally in 2015. This thesis focuses on two occupational groups that are at risk for developing adverse health effects from the time they spend in their working environments: cleaning workers and workers in
While urbanisation contributes to global biodiversity declines, flower-rich urban habitats may provide beneficial pollinator habitats. We investigated the potential of urban residential areas to contribute to pollinator diversity by analysing wild bee and hoverfly species richness and composition of species assemblages of summer-active species, sampled in 53 gardens across urban and rural landscap
Background and purpose — Many countries implemented strict lockdown policies to control the COVID-19 pandemic during March 2020. The impacts of lockdown policies on joint surgeries are unknown. Therefore, we assessed the effects of COVID-19 pandemic lockdown restrictions on the number of emergency and elective hip joint surgeries, and explored whether these procedures are more/less affected by loc
At the heart of this research are relational encounters between people and textile materials. As the title, Crafting Material Bodies, indicates, the research explores how human bodies are crafted by material bodies (costume) and vice versa. In the research textile materials and people are my co-creators and as co-creators they are invited to relate to, affect and become affected by other human bod
BACKGROUND: The knowledge about the prevalence of schizophrenia among people with intellectual disabilities (ID) is sparse, particularly concerning the distribution in different age groups.AIMS: To investigate the prevalence of diagnoses in the schizophrenia spectrum among people with ID compared with the general population (gPop).METHODS: This was an 8-year longitudinal register study. The partic
The field of linguistic relativity has its origin in the thoughts of the German philosopher Humboldt. He considered the language to be the formative organ of thought, the thought becomes externalized through sound in speech and thus perceptible to the senses. Thought and language are therefore one and inseparable from each other. Other prominent names in the field of linguistic relativity are Sapi
