The thesis examines the way that speech and gestures are used together to represent referents in discourse. The starting point is the generally acknowledged observation that gestures are a constitutive part of language (Kendon, 2004; McNeill, 1992). Gestures are used in combination with speech in the production of language, and are integrated with speech in the perception of language. But while th

One of the most robust neurochemical abnormalities reported in patients living with schizophrenia is an increase in dopamine (DA) synthesis and release in the dorsal striatum (DS). Importantly, it appears that this increase progresses as a patient transitions from a prodromal stage to the clinical diagnosis of schizophrenia. Here we have recreated this pathophysiology in an animal model by increas

How insects promote crop pollination remains poorly understood in terms of the contribution of functional trait differences between species. We used meta-analyses to test for correlations between community abundance, species richness and functional trait metrics with oilseed rape yield, a globally important crop. While overall abundance is consistently important in predicting yield, functional div

We report on a hybrid bioelectrochemical system that integrates an energy converting part, viz. a glucose/oxygen enzymatic fuel cell, with a charge-storing component, in which the redox features of the immobilized redox protein cytochrome c (cyt c) were utilized. Bilirubin oxidase and pyrroloquinoline quinone-dependent glucose dehydrogenase (PQQ-GDH) were employed as the biocatalysts for dioxygen

Löst organiskt kol (DOC) är en allmän beteckning på organiskt material upplöst i vatten. DOC är en viktig källa för energi, kol och näring som överförs från markbundna till akvatiska ekosystem. Exporten av DOC till akvatiska ekosystem kan bidra till kolbalansen i markbundna ekosystem och till försämrad vattenkvalitet. Pågående klimat- och markförändringar kommer att påverka både genereringen och tDissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. Ongoing climate and land cover changes will affect both DOC

Chemicals in the environment occur in mixtures rather than as individual entities. Environmental quality monitoring thus faces the challenge to comprehensively assess a multitude of contaminants and potential adverse effects. Effect-based methods have been suggested as complements to chemical analytical characterisation of complex pollution patterns. The regularly observed discrepancy between chem

Some recent studies showed that in vitro bioassays based on fish or human estrogen receptor (ER) activation may have distinct responses to environmental samples, highlighting the need to better understand bioassay-specific ER response to environmental mixtures. For this purpose, we investigated a 12-compound mixture in two mixture ratios (M1 and M2) on zebrafish (zf) liver cells stably expressing

Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. While bioassays have been used for water quality monitoring, there is limited knowledge regarding the effects of individual micropollutants and their relationship to the overall mixture effect in water samples. In this study, a battery of in vitro bioassays based on hum

Surface water can contain countless organic micropollutants, and targeted chemical analysis alone may only detect a small fraction of the chemicals present. Consequently, bioanalytical tools can be applied complementary to chemical analysis to detect the effects of complex chemical mixtures. In this study, bioassays indicative of activation of the aryl hydrocarbon receptor (AhR), activation of the

This study examined an econometric analysis of the macroeconomic determinants of carbon dioxide (CO2) emission in Nigeria, covering the periods between 1981 and 2016, employing both linear and non-linear Autoregressive Distributed Lag (ARDL & NARDL) models. The time series data used were sourced from the database of the World Bank Development Indicators, 2016 and Central Bank of Nigeria Statis

In two event-related potential studies, we investigated the processing of sentences with prefixal negation (unauthorized), sentential negation (not authorized) and no negation (authorized). We asked whether prefixal and sentential negation resulted in delayed processing. In Experiment 1, sentences such as “The White House announced that the new Obama biography was authorized/unauthorized/not autho

Measurement of the burning velocity of unstretched laminar hydrogen/air premixed flames suffers from large uncertainties owing to the highly diffusive nature of hydrogen that can give rise to flame instability. This paper reports on a numerical study of the structures and stability of laminar premixed CH4/O2/CO2 flames and H2/O2/N2 flames anchored to a heat-flux burner using a high-order numerical

This article looks to the philosophy of Gilles Deleuze in order to theorize the crucifixion of Jesus as event in early Christian literature. A Deleuzian view on the event is primarily articulated with the distinction between a sequential and a serial understanding of happenings, where the latter forms the basis for singular events. It is argued that Jesus' death is best considered a singular event

Bokcaféerna spelade en avgörande roll inom den västeuropeiska vänsterns tryck- och mediekultur under 1970-talet. Även i Sverige gjorde bokcaféerna omfattande avtryck inom kultur- och samhällslivet, till exempel genom att etablera den politiska pocketgenren. När fenomenet dog ut under nästa decennium försvann en betydande plattform för den radikala folkbildningen.
