The past few decades have seen an increasing demand for environmental information on which to make more informed decisions, strengthened by several international calls for improving available environmental information. In a democratic South Africa, the involvement of people in policy and decision-making processes has led to an even greater need for accessible information. In response to this deman

Preterm human neonates, contrary to preterm piglets, obtain immunoglobulins from their mothers via the placenta during intrauterine development. However, one should note that the majority of trans-placental transfer of immunoglobulins in humans takes place during the last trimester of pregnancy. It is also known that the feeding of limited amounts of colostrum or systemic infusion of small amounts

The article summarizes the results of work since 2010 to develop non- destructive energy dispersive X-ray fluorescence analysis (EDXRF) as a non-destructive method for determining the provenience of flint in northern Europe. Some 40 localities from Sweden, Denmark, Germany, Poland, and Ukraine have been sampled and analyzed. Trace elements have not proven particularly effective in drawing distinct

RATIONALE: Sepsis-induced acute kidney injury (AKI) is a common condition with high morbidity and mortality. Neutrophil-derived heparin-binding protein (HBP) induces vascular leakage and is a promising biomarker of sepsis-induced organ dysfunction. It remains unknown if HBP is prognostic of AKI in septic shock and if HBP could play a role in the pathophysiology of sepsis-induced AKI.OBJECTIVES: To

The motion of pre-existing edge dislocations in an infinite linear elastic body is studied. Motion is due to a quasi-statically steady-state growing crack. In the model, the dislocations glide if the force on the dislocation exceeds a critical value. Obtained results are changes in dislocation density, the shielding effect on the crack tip and residual stresses. The model is applied to an isotropi

BACKGROUND: Male arginine vasopressin 1a receptor knockout mice (V1aR(-/-)) display a phenotype of low triglycerides and high glucose concentrations and high-fat-diet-induced obesity and diabetes. OBJECTIVE: We investigated whether genetic variation of the human arginine vasopressin 1A (AVPR1A) gene is associated with phenotypic features resembling those of the V1aR(-/-) mouse. DESIGN: In a popula

Automatic detection of five language components, which are all relevant for expressing opinions and for stance taking, was studied: positive sentiment, negative sentiment, speculation, contrast and condition. A resource-aware approach was taken, which included manual annotation of 500 training samples and the use of limited lexical resources. Active learning was compared to random selection of tra

Cancer-associated fibroblasts (CAFs) regulate tumour growth, metastasis and response to treatment. Recent studies indicate the existence of functionally distinct CAF subsets. Suggested mechanisms whereby CAFs can impact on treatment response include paracrine signaling affecting cancer cell drug sensitivity and effects on tumour drug uptake. PDGFRβ is an important regulator of fibroblasts. Experim

We introduce an axiomatization for the coalgebraic fixed point logic which was introduced by Venema as a generalization, based on Moss' coalgebraic modality, of the well-known modal mucalculus. Our axiomatization can be seen as a generalization of Kozen's proof system for the modal mu-calculus to the coalgebraic level of generality. It consists of a complete axiomatization for Moss' modality, exte

Förbränning är både vår största källa till energi och ett stort hot mot miljön i form av föroreningar och växthusgaser. Ett par av de stora bovarna i sammanhanget är koldioxid och kväveoxider och de stora mängderna av dessa i atmosfären. Där bidrar koldioxid till den globala uppvärmningen i egenskap av växthusgas. Kväveoxider påverkar både miljö och människors hälsa negativt genom att bilda marknäCombustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. With some CCS-techniques the CO2 is repurposed in the combustion process together wi

Abstract: This thesis examines the non-dominant and self-subversive aspects of visuality in Roberto Bolaño’s 2666 through the lens of the philosophical discussion on representation, particularly in its post-structuralist context. The present research is grounded in the conviction that 2666 embodies the 20th-century crisis of representation and approaches the novel through an analysis of different

BACKGROUND: Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservative

Manual selection of finger trabecular bone texture regions on hand X-ray images is time-consuming, tedious, and observer-dependent. Therefore, we developed an automated method for the region selection. The method selects square trabecular bone regions of interest above and below the second to fifth distal and proximal interphalangeal joints. Two regions are selected per joint (16 regions per hand)

This work reports new experimental radiative lifetimes of six 3d2(3F)5s levels in singly ionized titanium, with an energy around 63 000 cm-1 and four 3d2(3F)4p odd parity levels where we confirm previous investigations. Combining the new 5s lifetimes with branching fractions measured previously by Pickering et al., we report 57 experimental log gf values for transitions from the 5s levels. The lif

We present results on the implementation of switches for a reconfigurable antenna at 60 GHz. The switches are realized by diodes, which are characterized by measurements on a coplanar waveguide test bed. From the measurements, we extract different circuit models. The models are used as lumped elements in a full wave simulation of a reconfigurable antenna, where it is shown that the different model
