Populärvetenskaplig sammanfattning: Rapakivigraniter är en speciell typ av graniter som uppträder minst hundra miljoner år efter det att orogena jordskorpebildande processer i det aktuella området har avslutats. De definierades först av finska geologer. Flera massiv har identifierats i Sverige och nu är rapakivigraniter kända från alla kontinenter. Märkligt är att de flesta har bildats under en beThe three principal mafic minerals, augite, ferro-edenite and ferrohornblende, show a progressive chemical evolution during the crystallisation of the Nordingrå rapakivi granite magma. Some crystals of augite have reacted with the liquid forming ferroedenite. Some ferroedenite is in turn altered into ferrohornblende. This order of mineral evolution has been determined from observations under the p

By use of a batch microcalorimeter of the thermopile type, heat production was measured in isolated populations of human peripheral blood cells exposed to defined immune complexes formed in vitro. It was found that most of the heat production recorded in whole blood after admixture of immune complexes occurs in the granulocytes. Under these conditions small but constantly higher activation values

Objective: To determine the circulation of poliovirus in three municipalities considered as transitory points for migrants in Colombia. Material and Method: Wastewater samples (n = 36) were collected from border municipalities, selected for greater transit of regular and irregular migrants, in the period between 2017-2019. The samples were concentrated and cultured following the World Health Organ

Abstract in Spanish El documento analiza la evolución que ha tenido la cooperación internacional con Centro América e identifica los retos futuros que enfrentarán las agencias bilaterales en el marco de la era global y el cumplimiento de los Objetivos de Desarrollo del Milenio. Para ello se describen las características principales de cuatro etapas por las cuales ha transitado dicha cooperación en

It has long been debated whether second language learning activities that contain authentic materials are more effective than their constructed and more grammatical counterparts, and there is still no clear consensus on whether one is more efficient than the other. This research paper investigated the writing proficiency of four students learning French at Lund University in Sweden, where one stud

This paper investigates the lexical immigration of “arabismos” (Arabic loanwords) in the Spanish language. It compares the differences between old arabismos (integrated during the Middle Ages) and modern arabismos (integrated in contemporary time) in terms of their adaptation to the Spanish norms of spelling, phonetics, semantics and morphosyntactic. It also analyses the use of the arabismos and t

This dissertation deals with conversational practices through which interactants manage issues of intersubjectivity, i.e. mutual understanding for all practical purposes. Intersubjectivity is understood in a procedural sense, and as built into the infrastructure of interaction, where each next action embodies aspects of how the previous action was understood. This understanding can be inspected by

This dissertation deals with the morphological development in written L2 French by Swedish learners. The thesis presents a detailed analysis of number marking and agreement in NPs and VPs, focusing mainly on the production of the morphemes –s (in NP) and the third person plural –nt (in VP). These agreements are particularly interesting in French where number morphology is often silent in the oral

Artikeln diskuterar möjligheterna och begränsningarna i äldres tillgänglighet till i IT-samhället under senare delen av 1990-talet. Resultatet från en intervjuundersökning (n=186)visar att äldre IT-användare kan kategoriseras i beroende, akriva och avancerade användare och att detta formas av tillgången, förmågan, förväntningarna, självbilden och dagliga restriktioner (sociala kontexten.
