In recent years, lithium production has been increasing as a result of the growing market demand. Salt-lake brines are one of the main sources of raw lithium, which can be concentrated and purified by natural evaporation. This time-consuming production causes a loss of around 85–95 % of the water contained in the extracted brine. In this context, new technologies could replace the current process

Forests are crucial for biodiversity, climate stability, and human well-being, yet rising pressures from climate change and conventional forestry practices threaten their resilience and sustainability. Approximately 30% of global forests are managed intensively, often as monoculture plantations, compromising biodiversity conservation, carbon sequestration, and ecosystem stability. Here, we propose

Construction using timber has seen a resurgence in light of global climate mitigation policies. Wood is a renewable resource, and engineered wood products are proving to be competitive against concrete and steel while having several advantages. However, while the renewable nature of wood in construction is a beneficial property for climate mitigation policies, the process of biodegradation introdu

To develop an innovative information and communication technology (ICT) tool intended to help older people in their search for optimal housing solutions, a first step in the development process is to gain knowledge from the intended users. Thus the aim of this study was to deepen the knowledge about needs and expectations about housing options as expressed and prioritized by older people, people a

The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into lignocellulosic biorefineries they can become a keystone in a future bioeconomy. In order to achieve this, pulp mills have to close their loops and focus on the optimal utilisa

1. IntroductionThe end of the 20th century was marked by the start of the third and so far final wave of biotechnology, the so-called white biotechnology, aiming to substitute chemical processes based on C2/C3 chemistry of oil and gas by biotechnological processes. The standard conversion process in biotechnology is fermentation, which is used to produce a wide range of bulk products such as antib

Some seabirds we encounter only fleetingly, as they fly by as we walk along the beach, or perhaps meet far out at sea when we take a boat trip. Others though we are more familiar with, such as the ‘seagulls’ that many will not even turn their head to appreciate. Yet, all seabirds have remarkable stories to tell, and we are fortunate now to live at a time where we can follow individual birds as theMost seabirds breed colonially, at which time they make central-place foraging trips. Parents must collect food both for themselves and for egg production/chick-rearing. How should they forage? I followed five species across two sites in Sweden in the Baltic Sea using GPS and time-depth recorder (TDR) devices, giving information on both flight and diving activity. I use a movement ecology approach

The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constrained by observations. For this, the fluorine abundance trend with metallicity spanning a wide range is required. Our aim is to determine stellar abundances of fluorine for. We determine the abundances from HF lines in i

Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

The study aims to establish the effectiveness of the Danish destination certification scheme – Destination 21. In order to accomplish this, an analytical framework, based upon current tourism and development theory, was constructed against which the scheme was tested. The analytical framework consists from three analyses examining the schemes framework, substance and applicability. It was found th

A 3D model at microscale by the lattice Boltzmann method (LBM) is proposed for part of an anode of a solid oxide fuel cell (SOFC) to analyze the interaction between the transport and reaction processes and structural parameters. The equations of charge, momentum, heat and mass transport are simulated in the model. The modeling geometry is created with randomly placed spheres to resemble the part o

This dissertation investigates the use of religious terms and symbols in politics. More specifically, it investigates Muslim politics. Its aim is to analyze the role of religious terms and symbols within a non-fundamentalist political party, namely the Sri Lanka Muslim Congress (SLMC), a Muslim political party that has been part of the democratic process in Sri Lanka since the 1980s. I thereby hop

This study attempts to determine how English Language teaching and learning methods in a Vietnamese classroom might affect learning output. A classroom observation using COLT (Communicative Orientation of Language Teaching–part A) and recordings of four Vietnamese children at grade 5 made immediately after the lesson concluded have been analysed. The analysis of the children' transcript is made ba

Popular Abstract in English Nowadays, cutting-edge technologies require devices to be small, ultrafast, and operational in a wide range of regimes. To fulfill these requirements we need to go beyond the traditional materials, i.e. to solids with novel, unconventional and tailorable properties. Great progress in this direction is conjectured to stem from materials in which the effect of inter-partiCutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. "unforeseen" useful properties are expected to be most likely found in systems with comple

Lignocellulose hydrolysate is an abundant substrate for bioethanol production. The ideal microorganism for such a fermentation process should combine rapid and efficient conversion of the available carbon sources to ethanol with high tolerance to ethanol and to inhibitory components in the hydrolysate. A particular biological problem are the pentoses, which are not naturally metabolized by the mai

The effect of varying the fraction of charged monomer units of the polyion in aqueous polyion-oppositely charged surfactant complex salts has been investigated. The complex salts used were based on cetyltrimethylammonium (C(16)TA(+)) with three different polymeric counterions: poly(acrylate) (PA(-)) or poly(acrylate) copolymerized with either dimethylacrylamide (PA(-)/DAM) or N-isopropylamide (PA(

Popular Abstract in Swedish Läkaren har en viktig roll när det gäller att tillförsäkra människor vård på lika villkor. Mötet mellan läkaren och patienten präglas alltid av maktobalans. Studier världen över visar att invandrarpatienter är en sårbar grupp eftersom invandrare generellt har sämre tillgång till vård, sämre förutsättningar för hälsa och sämre hälsotillstånd jämfört med majoritetspopulatPhysician and patient do not meet as equals in the consultation. It is the responsibility of the physician to actively work for better communication in order to provide equitable health care for all individuals. Immigrant patients are a vulnerable group, shown in studies all over the world to have less access to care, fewer opportunities for health, and poorer health compared to majority populatio

The Multi-plume Aerosol dynamics and Transport (MAT) model has been developed to study the dynamics of the particle size distribution in urban environments. The MAT model uses a novel multi-plume scheme for vertical dispersion and routines of the aerodynamics models AERO3. It treats the processes: emission from a near ground source, dilution with background air, deposition, coagulation and condens
