Plant communities as drivers of soil respiration: pathways, mechanisms, and significance for global change

Understanding the impacts of plant community characteristics on soil carbon dioxide efflux (R) is a key prerequisite for accurate prediction of the future carbon (C) balance of terrestrial ecosystems under climate change. However, developing a mechanistic understanding of the determinants of R is complicated by the presence of multiple different sources of respiratory C within soil - such as soil

Mitochondrial bioenergetic alterations after focal traumatic brain injury in the immature brain.

Traumatic brain injury (TBI) is one of the leading causes of death in children worldwide. Emerging evidence suggests that alterations in mitochondrial function are critical components of secondary injury cascade initiated by TBI that propogates neurodegeneration and limits neuroregeneration. Unfortunately, there is very little known about the cerebral mitochondrial bioenergetic response from the i

The Gaia-ESO Survey: properties of newly discovered Li-rich giants

Aims. We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with an evolutionary stage confirmed by CoRoT (Convection, Rotation and planetary Transits) data. We present a detailed overview of the properties of these 20 stars. Methods. Atmospheric parameters and abundances were derived in model atmosphere analyses using medium-resolution GIRAF

Protein Dimensions and Interactions at Immune-Cell Contacts

Immune cells, such as B and T cells, fight pathogens infecting the human body. To fulfil this function the immune cells need to form a contact during which different membrane proteins play an important role. A key event in this contact is the interaction between the T-cell receptor (TCR) and an antigenic peptide-presenting major histocompatibility complex (MHC) protein. If this interaction is suff

This thesis contains two studies focusing on motivation in learning and teaching French as a foreign language in Sweden. In the first study, the effect of three specifically designed pedagogical activities on learners’ Ideal French Self (IFrS) and Intended Effort (IE) was examined in a group of 15-year-old Swedish pupils. No significant difference could be found between the two intervention classe

The Cultural Semiotics of African Encounters : Eighteenth-Century Images of the Other

This a contribution to the cultural semiotics of African cultural encounters seen through the eyes of Swedish naturalists at the end of the eighteenth century. European travellers faced severe problems in understanding the alien African cultures they encountered; they even had difficulty understanding the other culture as a culture. They were not just other cultures that they could relate to, but

Place branding: A Nordic perspective

This paper examines the Nordic as an ideological, cultural, and geographical site from which to examine place branding. Although a number of studies have addressed Nordic place brands and branding, the peculiarity of branding within the Nordic welfare states remains understudied (Lucarelli et al., forthcoming 2019). The unusual open access to the field of practice granted to researchers (at least

Potential yield simulated by global gridded crop models : Using a process-based emulator to explain their differences

How global gridded crop models (GGCMs) differ in their simulation of potential yield and reasons for those differences have never been assessed. The GGCM Intercomparison (GGCMI) offers a good framework for this assessment. Here, we built an emulator (called SMM for simple mechanistic model) of GGCMs based on generic and simplified formalism. The SMM equations describe crop phenology by a sum of gr

Knowledge intensive business services in non-core areas : Preconditions and strategies for value creation and competitiveness

Kunskapsintensiva företagstjänster (KIBS) har en nyckelroll i den ekonomiska utvecklingen. Deras konkurrenskraft och värdeskapande processer bygger på komplexa samarbetsrelationer med kunder och andra aktörer. Av den anledningen har forskningen konventionellt lyft fram att dessa företags konkurrenskraft är starkt beroende av geografisk närhet till stora klient- och arbetsmarknader liksom till avanKnowledge intensive business services (KIBS) play a key role in economic development. Due to the complex and collaborative nature of their value creation processes, it is conventionally argued that they depend strongly on physical proximity to large client-, and labour-markets, as well as on closeness to advanced knowledge infrastructures. This thesis partially questions such conventional assumpti

Bullying, violence and mental distress among young people. Cross-sectional population-based studies in Scania, Sweden.

Aim: The overall aim was to investigate associations between bullying, violence and mental health among young people in Sweden. Specific aims were to investigate differences in exposure to peer victimization among disabled and non-disabled adolescents (Paper I), the influence of social support on the relationship between cyber harassment and mental distress among adolescents (Paper II), the associ

Decision Tree-Based Data Mining and Rule Induction for Identifying High Quality Groundwater Zones to Water Supply Management : a Novel Hybrid Use of Data Mining and GIS

Groundwater is an important source to supply drinking water demands in both arid and semi-arid regions. Nevertheless, locating high quality drinking water is a major challenge in such areas. Against this background, this study proceeds to utilize and compare five decision tree-based data mining algorithms including Ordinary Decision Tree (ODT), Random Forest (RF), Random Tree (RT), Chi-square Auto

Since 1995, agri-environmental support partly funded by the EU has formed the core of Finland’s agri-environmental policy. This system has had a variety of impacts on the relationship between agriculture and the environment. Today’s agri-environmental support is one of the packages included in the Rural Development Programme for Mainland Finland (2007–2013/2014), which both in itself and through t

Synaptic connections formed by grafts of different types of cholinergic neurons in the host hippocampus

The present experiment was performed to determine whether different types of grafted central cholinergic neurons are able to form synaptic contacts with host hippocampal neurons. Grafts from the septal-diagonal band area, which contain the neurons that normally innervate the hippocampal formation, were compared to those from the nucleus basalis magnocellularis region (NBM), the striatum, the ponto
