This work presents a comparative luminescence study of Pr3+ doped phase-pure BaLuF5 and mixed-phase BaLu2F8 – BaLuF5 materials synthesized via a hydrothermal route. The spectroscopic studies were mainly performed for phase-pure BaLuF5 and two mixed-phase materials, which, according to structural and phase compositional analysis, contained 90 or 70 wt% of orthorhombic BaLu2F8 and 10 or 30 wt% of cu

Lignin is one of the three predominant biopolymers that make up plants together with cellulose and hemicellulose, and it is the only plant component that is based on aromatic units. The industrial kraft pulping process generates large amounts of lignin, which is currently used to generate heat for the process. The subject of this thesis is the valorization of kraft lignin into valuable chemicals.

The Last Hour is one of plan b's series of works with spontaneous, real time text. Like How Do You Keep Talking, what we say is not rehearsed or set but happens in the moment. We set ourselves the task of saying everything we have left out of our relationship until now, as if we had one last hour together. We sit behind a long table with two microphones, dressed formally as if attending a press co

ObjectivesThe formation of episodic memories is critically determined by how we visually sample the world over time via sequences of eye movements. Nonetheless, in the neuroscience of human memory, memory encoding has almost exclusively been studied in experimental paradigms where the study material is presented in a single fixed location on the screen, and where eye movements are treated as artif

Understanding the mechanisms that regulate the dynamics of spatially structured populations (SSP) is a critical challenge for ecologists and conservation managers. Internal population processes such as births and deaths occur at a local level, while external processes such as dispersal take place at an inter-population level. At both levels, density dependence is expected to play a critical role.

Hur många roller ska skogen ta sig an? Skogen kan ta an många olika roller. Den kan vara en vacker vandringsmiljö. Kanske ett förvaringsutrymme för koldioxid? Eller till och med en viktig källa för bioenergi. Skogens förmåga att bidra med flera funktioner är fantastiskt men precis som andra naturresurser är förrådet begränsad. Dessutom är skogen en central del i klimatarbetet där dess funktion soThe land use, land-use change, and forestry sector (LULUCF) has historically been rather unregulated. Recent political developments have put pressure on countries to implement practices that increase net greenhouse gas (GHG) removals and improve the state of carbon sinks. One of these political developments is the European Union’s (EU) LULUCF Regulation, which as of now obligates Member States (MS

Background Approximately one-third-of patients with transient new-onset atrial fibrillation (AF) during hospitalization for noncardiac surgery or medical illness will have recurrent AF within 1 year when assessed using two 14-day ECG monitors. The proportion of patients that would be diagnosed with recurrent AF with less monitoring is unknown. Methods We used data from a prospective cohort of part

Chondrocytes isolated from the Swarm rat chondrosarcoma were incubated in culture with [1-3H]glucose for 30 min to 8 h. Labeled proteoglycans were isolated, treated with borohydride under alkaline conditions, and the three complex sugar structures purified: N- and O-linked oligosaccharides and chondroitin sulfate chains. The amount of incorporated radioactivity into each component sugar was analyz

Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have several limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically. Exp

Background: Women who deliver pre-term have been reported to have increased future risks of cardiometabolic disorders. However, their long-term risks of ischemic heart disease (IHD) and whether such risks are due to shared familial factors are unclear. A better understanding of these risks may help improve long-term clinical follow-up and interventions to prevent IHD in women. Objectives: The purp

Objective. The effects of a promising new appetite suppressor named "thylakoids" (membrane proteins derived from spinach leaves) were examined in a single meal in man. Thylakoids inhibit the lipase/colipase hydrolysis of triacylglycerols in vitro and suppress food intake, decrease body-weight gain and raise the satiety hormone cholecystokinin (CCK) in rats, but their effects in man remain unclear.

Objective: Compare perioperative course and long-term mortality after liver resection for colorectal cancer (CRC) metastases between patients who had preoperative treatment with portal vein embolization (PVE) and chemotherapy or chemotherapy alone. Methods: Among patients undergoing liver resection for CRC metastases following preoperative chemotherapy treatment, 17 patients who had received pre

In a society increasingly characterized by cultural heterogeneity and where trust issues are becoming ever more important, new demands and dilemmas arise related to organizations’ strategic communication. This study investigates the struggles of contemporary organizations to achieve credibility and strengthen their social legitimacy as actors in Sweden’s multicultural society. The empirical case c

Popular science Carbon cycle has great importance in all time scales for its inter-connected relation and response with climate system. Increased anthropogenic emission of CO2 is alleged to impact the climate system in the future, which will affect the feedback between carbon cycle and climate change. In this project, a climate-carbon cycle feedback analysis has been conducted by using long simula

Varför minskar Backsippan i Skåne? Backsippa (Pulsatilla vulgaris) är en mycket välkänd och älskad växt, inte minst eftersom den med sina stora lila blommor är så lätt att känna igen. Den blommar i april-maj och växer på torra hedar och näringsfattiga ängar. Det är viktigt att området där backsippan växer betas. Den är fridlyst i hela Sverige och blev nyligen även rödlistad på den nationella rödThe now redlisted P. vulgaris has continuously declined throughout its distribution range. In this project, 72 localities in eastern Scania, southern-most Sweden, were investigated, 19 of them contained viable populations of P. vulgaris and in the remaining 53 it had gone extinct. The localities were assessed as to why the extinction had occurred, and if the locality still appeared to be suitable

I dagens samhälle används stora mängder vatten som måste renas innan det släpps tillbaka ut i naturen. Rening av vattnet sker i avloppsreningsverk som ska minska mängden organiskt material och mängden näringsämnen i vattnet innan det släpps ut. Om vattnet inte renas finns det en risk för negativ påverkan på sjöar och vattendrag, t.ex. övergödning. Fosfor är ett av de näringsämnen som finns i avlWastewater is an excellent source of nutrients and energy. By treating the wastewater in a clever way, it is possible to both recycle nutrients and recover energy, and thereby create opportunities for a sustainable system. In conventional wastewater treatment where the activated sludge process is used, aeration is needed and a lot of biomass is produced. In regions with warmer climate, or if low-v

Datorsimuleringar blir ett allt viktigare verktyg för att förstå, utveckla och effektivisera alla sorters processer och produkter i vårt samhälle. Det är ofta svårt att exakt efterlikna verkligheten, och för att göra simuleringarna möjliga används ofta modeller som förenklar verkligheten.In this master thesis computational fluid dynamic simulations of two plate heat exchanger channels have been performed in Ansys CFX. The full geometry of the channels has not been included, the channels were modeled with a flat geometry instead of a corrugated pattern. To account for the effect of the corrugation on the pressure drop, one-time pressure losses and momentum sources were added in the

Jämförelse av två flugfamiljers mångfald i två olika naturtyper Djurs mångfald är inte bara intressant utan även viktigt för att vår värld ska fungera i harmoni och kretsloppen ska slutas och gå runt. Vissa djur behövs för att bryta ned vissna växter och andra för att hålla insekters antal i schack. Några djur kan även vara tecken på om naturen mår bra eller dåligt. Olika naturtyper är hem för olBiodiversity is a big part of the understanding of our life and its surroundings. Only a fraction of the earth’s species are known and many are yet to be found. When describing new species often both molecular and morphological data is needed to fully resolve cryptic taxa. In this study, the diversity of two Diptera families, soldier flies (Stratiomyidae) and thick-headed flies (Conopidae), have b

I och med införandet av Sällskapsdirektivet (2014/26/EU) lyckades EU:s arbete med att harmonisera området för kollektiv rättighetsförvaltning. Den nya digitala miljön hade skapat ett större behov för EU att reglera området och bidra till att alla medlemsstater utgår från samma regler. Tidigare hade organisationernas förvaltning sett annorlunda ut eftersom det saknades en harmoniserad reglering. DiWith the introduction of the Collective Rights Management Directive (2014/26/EU), the EU's efforts to harmonize the area of collective rights management succeeded. The new digital environment had created a greater need for the EU to regulate the area and to contribute to all Member States based on the same rules. In the past, the management of the organizations had looked different because the
