The main function of a membrane is to control the exchange of matter between the surrounding regions. As such, accurate modeling of membranes is important to properly describe their properties. In many cases in both biological systems and technical applications, the membranes are composite structures where transport properties may vary between the different sub-regions of the membrane. In this wor

Grounded in social exchange theory (SET) this paper presents research on non-collaborative behaviour among accommodation businesses within their spatial context. The study adopts semi-structured interviews of 14 co-located accommodation businesses in Christchurch, New Zealand. The findings reveal three categories of non-collaborative factors that influence business behaviour, namely (1) resource-b

For the class of de Branges-Rovnyak spaces H(b) of the unit disk D defined by extreme points b of the unit ball of H∞, we study the problem of approximation of a general function in H(b) by a function with an extension to the unit circle T of some degree of smoothness, for instance satisfying Hölder estimates or being differentiable. We will exhibit connections between this question and the theory

1. Challenging calibration of complex models can be approached by using prior knowledge on the parameters. However, the natural choice of Bayesian inference can be computationally heavy when relying on Markov Chain Monte Carlo (MCMC) sampling. When the likelihood of the data is intractable, alternative Bayesian methods have been proposed. Approximate Bayesian Computation (ABC) only requires sampli

It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. With each additional increment of warming, climate change is impacting ecosystems through changes in average conditions, climate variability, coupled with other associated changes such as biodiversity loss an

Transition metals such as copper and zinc are essential elements required for the survival of most organisms, from bacteria to humans. Yet, elevated levels of these elements are highly toxic. The Copper TRansporter protein family (CTRs) represents the only identified copper uptake proteins in eukaryotes and hence serves as key components for the maintenance of appropriate levels of the metal.

This open access book offers a detailed study of the foundation and expansion of the Dutch Cape Colony to ask why certain regions in the global south became European settler societies from the 16th century onwards.Examining the different factors that led to the creation of the Cape Colony, Erik Green reveals it was a gradual process, made up of ad hoc decisions, in which the agency of indigenous p

Migratory birds must make complex decisions to use wind to their advantage during flight and increasing flight performance is particularly important while crossing ecological barriers. Age-related differences in how birds deal with wind have suggested experience improves necessary skills in gaining positive wind support. However, differences in wind support between age groups over ecological barri

Aim: The aim of this study was to explore the relevance of asking young psychiatric patients about childhood symptoms of attention deficit hyperactivity disorder (ADHD).Method: A total of 180 young adults (18-25 years of age) from a general psychiatric out-patient clinic in Uppsala filled in the Child and Adolescent Psychiatric Screening Inventory-Retrospect (CAPSI-R) as part of the diagnostic pro

Adipose-derived mesenchymal stem cells (ADSCs) are promising candidates for novel cell therapeutic applications. Hibernating brown bears sustain tissue integrity and function via unknown mechanisms, which might be plasma borne. We hypothesized that plasma from hibernating bears may increase the expression of favorable factors from human ADSCs. In an experimental study, ADSCs from patients with isc

Femtosecond two-dimensional Fourier transform spectroscopy is used to determine the static bandgap inhomogeneity of a colloidal quantum dot ensemble. The excited states of quantum dots absorb light, so their absorptive two-dimensional (2D) spectra will typically have positive and negative peaks. It is shown that the absorption bandgap inhomogeneity is robustly determined by the slope of the nodal

This thesis examines the perception of hierarchy and how student activists have challenged hierarchy in the youth-led protests through attacking symbols of hierarchy and authority. Hereby, the research is based on in-depth interviews with student activists form Bangkok, linking it to the contemporary and historical development of the Thai social order. The findings are analysed through meaning-mak

The replacement of plastic microbeads with biodegradable alternatives is essential due to the environmental persistence of plastics and their accumulation within the human food chain. Hypothesis: Cellulose microbeads could be such alternative, but their production is hindered by the high viscosity of cellulose solutions. It is expected that this viscosity can be harnessed to induce filament thinni

Understanding how and why soil microbial communities respond to temperature changes is important for understanding the drivers of microbial distribution and abundance. Studying soil microbe responses to warming is often made difficult by concurrent warming effects on soil and vegetation and by a limited number of warming levels preventing the detection of non-linear effects. A unique area in Icela

Nanometric cutting of a single crystal copper workpiece of different crystallographic orientations by a stiff cylindrical cubic diamond tool has been investigated by MD simulations using the freeware LAMMPS. The chip evolves during the cutting process and forms depending on crystal orientation, cutting velocity and tool geometry. It was found that no significant difference in the cutting force mag

Building on the base of the existing telescopes of the Event Horizon Telescope (EHT) and ALMA, the next-generation EHT (ngEHT) aspires to deploy ∼10 more stations. The ngEHT targets an angular resolution of ∼15 microarcseconds. This resolution is achieved using Very Long Baseline Interferometry (VLBI) at the shortest radio wavelengths ∼1 mm. The Submillimeter Array (SMA) is both a standalone radio

Medborgarskap är en viktig status för individen. Medborgarskap innebär både rättigheter och skyldigheter för staten och för individen. Att byta och förvärva ett nytt medborgarskap är en stor ockasion i en persons liv. Denna uppsats kommer att granska kriteriet hederligt levnadssätt som återfinns i 11 § femte punkten MedbL. Intressant nog har detta kriterium utvecklats främst genom praxis. Denna uCitizenship is an essential status for an individual. It entails both rights and obligations for both the state and the individual. To change and gain new citi-zenship is a monumental occasion in an individual’s life. This essay will ex-plore the criterium of honorable living within the 11 § fifth point in the Swe-dish citizenship law. Interestingly enough, this one has chiefly developed through

Bakgrund Handhållen dynamometer (HHD) är ett instrument som inom fysioterapi används för att mäta muskelstyrka. Mätinstrumentets reliabilitet och validitet har undersökts och fastställts under de senaste decennierna, men få studier har jämfört olika typer och modeller med varandra. Syfte och frågeställningar Syftet med denna studie är att jämföra en tryck-HHD (Echo Wireless Muscle Tester) med en d
