Based on multiphase field conception and integrated with the idea of vectorvalued phase field, a phase field model for typical allotropic transformation of solid solution is proposed. The model takes the non-uniform distribution of grain boundaries of parent phase and crystal orientation into account in proper way, as being illustrated by the simulation of austenite to ferrite transformation in lo
Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. In order to study ultrafast phenomena, time-resolved techniques such as pump-probe experiments, involving ultrafast light pulses, are necessary. Fo
Den här avhandlingen berör två olika forskningsområden som är relaterade till fysiken för nanosystem. Det första området rör kvantkorrelationer och sammanflätning mellan elektroner i nanosystem, med ett särskilt fokus på hur man kan generera elektronisk orbital sammanflätning på tidsskalor mycket kortare än dekoherenstiden och hur man kan göra detektionen av sammanflätning enklare experimentellt. This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes. The second topic concerns heat
Particles that are a hundred- to ten thousand times smaller than the width of a hair are commonly referred to as colloidal particles. Colloidal particles occur in a variety of products, like foodstuffs (marmelade and dairy products), construction materials (cement) and stained glass. In water, these particles are strongly affected by the Brownian force: an force that was discovered in 1827 by the Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction. Mixing two microgels that collapse at different

Platinum(II) complexes of the type [Pt(thioether)2Cl]+(thioether = dimethyl sulfide, thioxane) are capable of abstracting a phenyl group from the BPh4 counterion with formation of trans[Pt(thioether)2ClPh] compounds. Thermal reactions proceed both in the solid phase and in nitromethane solution at elevated temperature and have preparative importance. Phenylation of the Pt(II) centre also occurs inPlatinum(II) complexes of the type [Pt(thioether)2Cl]+(thioether = dimethyl sulfide, thioxane) are capable of abstracting a phenyl group from the BPh4 counterion with formation of trans[Pt(thioether)2ClPh] compounds.

A Bayesian assessment of the probability that the defendant in a criminal trial is guilty depends on the presumed base rate for guilt and the estimated likelihoods of the evidence. This article explores how the base rate shall be determined. Bayesian scholars have recommended a base rate of 1/N, where N is the number of ‘possible perpetrators’, but it is unclear how the reference class of possible
Popular Abstract in Swedish Beräkningar med detaljerade kemiska reaktionssytem, med uppemot 1500 kemiska reaktioner, har utförts på HCCI-motorer, en experimentell motortyp som bygger på homogen kompressionsantändning. Resultaten jämfördes med experimentella mätningar och visade att beräkningar med god noggrannhet kan utföras, men att antändingsprocessen är mycket känslig för även små variationer iCalculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. It was found that calculations with good agreement could be accomplished, if using correct temperature, pressure and
Popular Abstract in Swedish Avhandlingen består av tre empiriska uppsatser inom internationell finansiell ekonomi. Den ekonometriska gemensamma nämnaren är att samtliga använda modeller är av komplex multivariat natur. Därför föreslås att de ekonometriska modellerna estimeras med hjälp av simulated annealing, en stokastisk optimeringsalgoritm som potentiellt löser de problem som vanligtvis är förkThis thesis consists of three self-contained empirical studies on international financial economics. The common economic theme is that all three studies deal with international stock market return and risk. The common econometric theme is that all estimations are performed using simulated annealing, a stochastic optimization algorithm in the Markov Chain Monte Carlo family, in an attempt to solve
In this article I explore the different and changing meanings of the concept “privat” in records from the Swedish Riksdag (state assembly) from the sixteenth to the beginning of the eighteenth century. I analyze how the concept was used in different contexts, such as questions concerning e.g. private and public religious practices, relations between individuals and communities, and relations betweIn this article I explore the different and changing meanings of the concept “privat” in records from the Swedish Riksdag (state assembly) from the sixteenth to the beginning of the eighteenth century.

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muniHow does violent conflict affect the spread of Covid-19?

Popular Abstract in Swedish Blodparasiter och blåmesar - en studie i rött och blått Alla har någon gång varit utsatta för parasiter. Man kan nog till och med vara säker på, att just i den stund du läser detta, finn's det någonstan's någon form av parasit som försöker attackera dig. I dom allra flesta fall misslycka's sådana försök tack vare ett mycket starkt och mångfacetterat försvar. Förutom deParasites are ubiquitous and can cause significant fitness reductions to their hosts. Therefore, selection for the evolution of host resistance should be strong. However, resistance may be costly and should be traded-off against other fitness related traits. Parasites could therefore have a significant impact on the evolution of fitness related characters of their hosts. It has been suggested that
