Rhizosphere priming effects differ between Norway spruce (Picea abies) and Scots pine seedlings cultivated under two levels of light intensity

The rhizosphere priming effect (RPE), which occurs in the presence of growing plant roots, may either stimulate or reduce the decomposition of soil organic matter (SOM). The carbon and nitrogen cycling in forest soils could be more rapid or slower due to the RPE, depending on the tree species and their growing conditions. Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) are two commer

Category-based induction in conceptual spaces

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for categ

Positive impacts of important bird and biodiversity areas on wintering waterbirds under changing temperatures throughout Europe and North Africa

Migratory waterbirds require an effectively conserved cohesive network of wetland areas throughout their range and life-cycle. Under rapid climate change, protected area (PA) networks need to be able to accommodate climate-driven range shifts in wildlife if they are to continue to be effective in the future. Thus, we investigated geographical variation in the relationship between local temperature

Entropy solutions and flux identification of a scalar conservation law modelling centrifugal sedimentation

Centrifugal sedimentation of an ideal suspension in a rotating tube or basket can be modelled by an initial-boundary-value problem for a scalar conservation law with a nonconvex flux function. The sought unknown is the volume fraction of solids as function of radial distance and time for constant initial data. The method of characteristics is used to construct entropy solutions. The qualitatively

The Impact of Anastomotic Leakage on Long-term Function after Anterior Resection for Rectal Cancer

BACKGROUND: It is still not clear whether anastomotic leakage after anterior resection for rectal cancer affects long-term functional outcome. OBJECTIVE: This study aimed to evaluate how anastomotic leakage following anterior resection for rectal cancer influences defecatory, urinary, and sexual function. DESIGN: In this retrospective population-based cohort study, patients were identified through

Lärares användning av digitala resurser i undervisningen : "Kombinationen av ett praktiskt verktyg och en skicklig lärare"

AbstractThis thesis investigates the use of digital resources in education with a 1-1 computer to student ratio. Studies were performed with a sociocultural perspective and in the light of the theory of affordances. The two studies differ methodologically but the shared topic is teachers’ usage of digital resources. Previous studies have shown that using digital resources to promote collaboration,

Tidal Inlets Hydraulics and Morphological Modeling: An application to Mundaú Lagoon, Brazi

Tidal inlets are narrow channels connecting coastal lagoons to the sea and in this way controlling the exchange of water while serving as navigational pathways. These important components of the coast are also very dynamic environments, having their morphology determined by multiple sediment transport processes, making tidal inlets difficult to model. Expected future sea level rise imposes an adde

Essays on Panel Data with Multidimensional Unobserved Heterogeneity

This thesis contributes to econometric methodology in terms of estimation and inference in static panel data models with unobserved multidimensional heterogeneity. When not properly accounted for, unobserved heterogeneity may introduce bias into the parameter estimates associated with covariates of interest, such as treatment indicators or determinants of macroeconomic indicators. A common way of

The psychopharmacology of Huntington disease

Huntington disease (HD) is a hereditary neurodegenerative disorder caused by an expanded cytosine–adenine–guanine triplet repeat in the huntingtin gene. The current diagnosis is based on the presence of typical motor signs in combination with a positive gene test. The motor onset of the disease is usually between 30 and 50 years of age, and the disease then progresses over around 20 more years. No

Hypoxia attenuates trastuzumab uptake and trastuzumab-emtansine (T-DM1) cytotoxicity through redistribution of phosphorylated caveolin-1

The antibody drug conjugate trastuzumab-emtansine (T-DM1) offers an additional treatment option for patients with HER2-amplified tumors. However, primary and acquired resistance is a limiting factor in a significant subset of patients. Hypoxia, a hallmark of cancer, regulates the trafficking of several receptor proteins with potential implications for tumor targeting. Here, we have investigated ho

Reconstructing intragranular strain fields in polycrystalline materials from scanning 3DXRD data

Two methods for reconstructing intragranular strain fields are developed for scanning three-dimensional X-ray diffraction (3DXRD). The methods are compared with a third approach where voxels are reconstructed independently of their neighbours [Hayashi, Setoyama & Seno (2017). Mater. Sci. Forum, 905, 157-164]. The 3D strain field of a tin grain, located within a sample of approximately 70 grain

Genetic and demographic vulnerability of adder populations : Results of a genetic study in mainland Britain

Genetic factors are often overlooked in conservation planning, despite their importance in small isolated populations. We used mitochondrial and microsatellite markers to investigate population genetics of the adder (Vipera berus) in southern Britain, where numbers are declining. We found no evidence for loss of heterozygosity in any of the populations studied. Genetic diversity was comparable acr
