The surface charging behavior as a function of pH and isoelectric points (IEPs) of single-crystal α-Al2O3 (0001) and (1102) and α-Fe2O3 (0001) was determined by streaming potential measurements using an electrokinetic analyzer. The IEPs of α-Al2O3 (0001) and (11-02)$(1\overline1 02)$ and α-Fe2O3 (0001) were found to be 4.5, 5.1, and 6.5, respectively. These IEP values for oriented single crystals
Joint diseases are often characterized by inflammatory processes that result in pathological changes in joint tissues, including cartilage degradation and release of components into the synovial fluid. The complement system plays a central role in promoting the inflammation. Because several cartilage proteins are known to interact with complement, causing either activation or inhibition of the sys
In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or
Lower system temperatures in district heating (DH) grids are important factors for system efficiency. Lower system temperatures lead, for example, to lower heat losses and higher production unit efficiency. One obstacle to lower supply temperatures are so-called bottlenecks in DH networks. Bottlenecks are areas in DH networks of very low differential pressure, which makes it difficult to supply th
Single-chain variable fragments (scFv) are widely used in several fields. However, they can be challenging to purify unless using expensive Protein L-based affinity adsorbents or affinity tags. In this work, a purification process for a scFv using mixed-mode (MM) chromatography was developed by design of experiments (DoE) and proteomics for host cell protein (HCP) quantification. Capture of scFv f
Since the mid 1970's, when Adey discovered that extremely-low-frequency electromagnetic field (ELF EMF) may affect the calcium ions efflux from various cells, bioeffects of non-ionizing radiation (NIR) have become the subject of growing interest and numerous research projects. At present, the fact that NIR exerts both stimulatory and inhibitory effects on different physiological cellular parameter
The Convention on Biological Diversity (CBD) was designed in accordance with the framework protocol approach, which comprises treaty bodies such as Conferences of the Parties (COP) and compliance mechanisms and sets out broad standards to be made more precise through the making of protocols.

Central limit theorems for linear statistics of lattice random fields (including spin models) are usually proven under suitable mixing conditions or quasi-associativity. Many interesting examples of spin models do not satisfy mixing conditions, and on the other hand, it does not seem easy to show central limit theorem for local statistics via quasi-associativity. In this work, we prove general cen
A level crossing predictor or alarm system with prediction horizon k is said to be optimal if it, at time t detects that an upcrossing will occur at time t + k, with a certain high probability and simultaneously gives a minimum number of false alarms. For a Gaussian stationary process, the optimal level crossing predictor can be explicitly specified in terms of the predicted value of the process i
Popular Abstract in English This thesis concerns experiments of heat transfer in a rectangular channel with ribs and an obstacle. Liquid crystal thermography (LCT) is used to record the temperature fields in the experiments. LCT is based on measurement of the color response of a heated surface. When illuminated with a white light, the liquid crystals react to temperature changes by changing color,This thesis presents experimental investigations of local heat transfer in a rectangular channel (aspect ratio AR = 4) with continuous transverse ribs as well as an obstacle. Liquid crystal thermography (LCT) is employed to obtain the temperature fields in the heat transfer experiments. The liquid crystal applied here has a red start at 35°C and a bandwidth of 1°C. The work consists of (1) periodi
Popular Abstract in Swedish Kollektiva substantiv definieras som substantiv som trots att de är singulara till formen betecknar en grupp av individer och som kan uppträda tillsammans med singulara och plurala verb och pronomina ('it'/'they'). Avhandlingen beskriver variation i kongruens vid kollektiva substantiv i amerikansk, brittisk och australiensisk engelska. Denna variation ses i exemplen nedThis thesis concerns agreement with collective nouns in American, British and Australian English. It is based on material from newspaper corpora and spoken corpora. The findings suggest that dialectal, stylistic, diachronic, syntactic and semantic factors interact in the selection of singular and plural agreement. It was shown that there are differences between regional varieties, between speech a
The aim of this report is to establish recommendations for reviewing, reporting, and conducting research during the post-resuscitation period in hospital. It defines data that are needed for research and more specialised registries and therefore supplements the recently updated Utstein template for resuscitation registries. The updated Utstein template and the out-of-hospital "Chain of Survival" d
Purpose The paper proposes a framework for the successful deployment of Industry 4.0 (I4.0) principles in the aerospace industry, based on identified success factors. The paper challenges the perception of I4.0 being aligned with de-skilling and personnel reduction and instead promotes a route to successful deployment centred on upskilling and retaining personnel for future role requirements. Desi
In recent years, social work with migrants and ethnic minorities has developed as a field of research and practice. Further, it is recognised in the literature that the increased processes of human mobility in today’s societies have driven a growing focus on inclusive cities, especially in larger urban areas where ethnic diversity and cultural heterogeneity can be found alongside newly arrived mig
This paper investigates how stakeholders respond to digital feasibility study images to augmented reality (AR), with the purpose to determine if AR could be the right practical application to create Virtual tourism. Based on the visitors’ perspective via qualitative interviews, the goal is to explore whether a digitalization in a realistic way, manages to mediate the concealed time layers and othe
Water related problems are characterized by complexities, uncertainties, and conflicting interests and there is no single “optimal” way to approach these “wicked” problems. Model-assisted participatory processes have been suggested as one way to meet these challenges. However, the use of models as ascenario tools for local planning of mitigation and adaptation strategies addressing environmental c
The energy hub concept is gradually getting popular due to its capability to integrate renewable energy technologies into the energy grid with a minimum impact. Designing distributed energy hubs is a challenging task due to the coupling of optimum dispatch and energy system sizing problems. Operation of the system needs to be considered for 8760 time steps and energy system sizing optimization can

Lead-based perovskite nanocrystals (NCs) have outstanding optical properties and cheap synthesis conferring them a tremendous potential in the field of optoelectronic devices. However, two critical problems are still unresolved and hindering their commercial applications: one is the fact of being lead-based and the other is the poor stability. Lead-free all-inorganic perovskite Cs3Bi2X9 (X=Cl, Br,
Context. The radial metallicity distribution in the Galactic thin disc represents a crucial constraint for modelling disc formation and evolution. Open star clusters allow us to derive both the radial metallicity distribution and its evolution over time. Aims. In this paper we perform the first investigation of the present-day radial metallicity distribution based on [Fe/H] determinations in late
