Altruistiska handlingar hos extroverta: en studie om extraversion och motivation

Denna studie undersökte sambandet mellan altruism, extraversion och motivation. Ett av personlighetsdragen i femfaktorsmodellen är extraversion. Detta personlighetsdrag testades som en möjlig prediktor för altruistiskt beteende. Dessutom undersöktes motivation som en ytterligare faktor bakom altruism. Deltagarna (N = 68) besvarade en enkät från online bestående av tre självskattningsskalor. ExtravThis study examined the relationship between altruism, extraversion, and motivation. One of the personality traits in the five-factor model is extraversion. This personality trait was tested as a potential predictor of altruistic behavior. Additionally, motivation was investigated as another factor contributing to altruism. Participants (N = 68) completed a questionnaire from online consisting of

Prenatal Psychosocial Determinants of Neonatal Brain Structure

Accumulating research shows that maternal mental health during pregnancy is linked to early neurodevelopmental changes in the offspring. Yet, there is a gap in examining how multiple prenatal risk and resilience factors are associated with early brain development. Therefore, this study explored multiple maternal and paternal psychosocial factors during pregnancy, and their link to neonatal brain s

The developmental trajectory of rhythmic abilities in humans and singing primates

Rhythmicity is a composite competence that spans perceptual, motor, and socio-cognitive abilities. This is highly salient when adopting a developmental perspective, as we do in this chapter that reviews data from humans and other singing primate taxa with a close (gibbons) or remote (indri lemurs) phylogenetic relatedness to our species. The findings we review show that rhythmicity develops as an

Morphology development during single droplet drying of mixed component formulations and milk

We report on the influence of selected components and their mixtures on the development of the morphology during drying of single droplets and extend the results to the morphology of whole milk powder particles. Sessile single droplet drying and acoustic levitation methods were employed to study single droplet drying. The influence of carbohydrates (lactose and maltodextrin DE12) and proteins (mic

Freeze-dried and re-hydrated liquid crystalline nanoparticles stabilized with disaccharides for drug-delivery of the plectasin derivative AP114 antimicrobial peptide

Liquid crystalline nanoparticles (LCNPs), e.g. cubosomes and hexosomes, are receiving more and more attraction as drug delivery vehicles. Dry powder formulation that forms LCNPs upon hydration can be advantageous to make new routes of administration accessible. In this work, we investigate use of three disaccharides (lactose, trehalose and sucrose) as protective matrices for glycerol monooleate ba

Milling induced amorphisation and recrystallization of α-lactose monohydrate

Preprocessing of pharmaceutical powders is a common procedure to condition the materials for a better manufacturing performance. However, such operations may induce undesired material properties modifications when conditioning particle size through milling, for example. Modification of both surface and bulk material structure will change the material properties, thus affecting the processability o

The Impact of Variable DOC Concentrations on Acidification Assessments

Dissolved organic carbon (DOC) affects the acidity in soil and lake waters and buffers both against acidification and against recovery from acidification. Current acidification assessments, based on the widely used MAGIC (Model of Acidification of Groundwater In Catchments) model, often assume constant DOC concentrations through time, but observations suggest this assumption may not be warranted.

AFM Colloidal Probe Measurements Implicate Capillary Condensation in Punch-Particle Surface Interactions during Tableting

Adhesion of the powders to the punches is a common issue during tableting. This phenomenon is known as sticking and affects the quality of the manufactured tablets. Defective tablets increase the cost of the manufacturing process. Thus, the ability to predict the tableting performance of the formulation blend before the process is scaled-up is important. The adhesive propensity of the powder to th

Porous calcium carbonate as a carrier material to increase the dissolution rate of poorly soluble flavouring compounds

Two different food grade functionalised porous calcium carbonates (FCC), with different pore size and pore size distributions, were characterised and used as carrier materials to increase the dissolution rate of poorly soluble flavouring compounds in aqueous solution. The loading level was varied between 1.3% by weight (wt%) and 35 wt%, where the upper limit of 35 wt% was the total maximum loading

Determination of interfacial amorphicity in functional powders

The nature of the surfaces of particles of pharmaceutical ingredients, food powders, and polymers is a determining factor for their performance in for example tableting, powder handling, or mixing. Changes on the surface structure of the material will impact the flow properties, dissolution rate, and tabletability of the powder blend. For crystalline materials, surface amorphization is a phenomeno

Effect of shell microstructure on oil migration and fat bloom development in model pralines

This study investigated the influence of shell microstructure on oil migration and fat bloom development in chocolate model systems. The microstructure of the model shells was varied by means of tempering or seeding cocoa butter and the addition of non-fat particles. Further, the impact of different storage conditions was studied. By using a set of novel analytical techniques the migration rate co

Databasskydd

The capacity to assemble, store, and make available information in databases is ever growing. This development has accelerated in recent decades, driven by the advent and increased use of digital networks. Already at an early stage, it led to demands for legal protection of databases. In most countries databases have been protected in national legislation based on copyright principles. However, th

On Uncertainty, Decision Values and Innovation

This paper contains a description, an alignment and a joint approach for technology readiness development with a three phases support of decision value analyses. The three phases are separated into the decision value forecasting, decision value analysis and the technology value quantification supporting the technological concept formulation and experimental testing, the prototype development and t

Reconstructing Stress Resultants in Wind Turbine Towers Based on Strain Measurements

Support structures of offshore wind turbines are subject to cyclic stresses generated by different time-variant random loadings such as wind, waves, and currents in combination with the excitation by the rotor. In the design phase, the cyclic demand on wind turbine support structure is calculated and forecasted with semi or fully probabilistic engineering models. In some cases, additional cyclic s

Combined Analysis-L1 and Total Variation ADMM with Applications to MEG Brain Imaging and Signal Reconstruction

In this article, we propose an efficient method for solving analysis-l1-TV regularization problems with a multi-step alternating direction method of multipliers (ADMM) approach as the fast solver. Additionally, we apply it to a real-data magnetoen-cephalography (MEG) brain imaging problem as well as to signal reconstruction. In our approach, the inverse problem arising in MEG or signal reconstruct

On the evolution of floral traits : Variation in complex floral phenotypes across pollination environments

Pollinators play a central role in shaping the astounding diversity of angiosperm flowers. Flowers are complex, multidimensional, genetically and functionally integrated phenotypes, rendering it a challenge to quantify and interpret observed trait variation. Even variation in simpler trait measurements is a challenge to interpret, because of the multitude of selective agents and evolutionary proce
