Refining the history of Younger Dryas and Early Holocene glacier oscillations in the Borgarfjörður region, western Iceland

The lower Borgarfjörður region, western Iceland, has been central to the reconstructions of the dynamics and collapse of the Icelandic Ice Sheet during the deglaciation. Here, extensive stratigraphical sections and landforms provide a rare opportunity to study past glacier dynamics in this part of Iceland. Previous studies reveal that a large outlet glacier in Borgarfjörður advanced during the Lat

Predicted and measured user-related energy usage in newly built low-energy schools in Sweden

Literature and experience show that the differences between calculated and measured building energy performance still exist. The literature shows that user-related parameters are significant with regard to energy performance in low-energy buildings and this means that the choice of parameters is one of the main factors leading to this difference. However, the parameters themselves are associated w

Study of effects of axisymmetric endwall contouring on film cooling/heat transfer and secondary losses in a cascade of first stage nozzle guide vane

The film cooling and heat transfer on the endwall especially in the junction region of a vane/blade which encounters strong vortical flow is of great significance in turbomachinery. Achievement of excellent film cooling and aerodynamic performance by controlling the secondary flow in that region can lead to increased gas turbine efficiency. This study investigates axisymmetric endwall contouring p

Tritium in urine from members of the general public and occupationally exposed workers in Lund, Sweden, prior to operation of the European Spallation Source

A powerful neutron source, the European Spallation Source (ESS), is currently under construction in Lund, Sweden (~90 000 inhabitants). Levels of tritium (3H) in urine were estimated in members of the public in Lund and employees at the ESS using liquid scintillation counting, to obtain baseline levels before the start of operation of the ESS. These were compared with levels in other occupationall

Effect of membrane composition on DivIVA-membrane interaction

DivIVA is a crucial membrane-binding protein that helps to localize other proteins to negatively curved membranes at cellular poles and division septa in Gram-positive bacteria. The N-terminal domain of DivIVA is responsible for membrane binding. However, to which lipids the domain binds or how it recognizes the membrane negative curvature remains elusive. Using computer simulations, we demonstrat

Inclusion of the 3P0 model in PYTHIA 8

The spin effects in the hadronization process have been included for the first time in the PYTHIA 8 event generator. The spin effects are limited to the production of pseudo-scalar mesons and are obtained from the propagation of the quark polarization along the fragmentation chain according to the rules of the so-called 3P0 model. The interface between PYTHIA 8 and the package of the 3P0 model is

Tool wear by dissolution during machining of alloy 718 and Waspaloy : a comparative study using diffusion couples

The wear of metal cutting tools is known to take place by the combined and simultaneous effects of several wear mechanisms. Knowledge of the relative contribution of the individual wear mechanisms is required to understand and predict the tool wear during cutting different workpiece materials and alloys. It has been shown previously that machining two heat resistant superalloys, alloy 718 and Wasp

Innovation by foreign researchers : relative influences of internal versus external human capital

Innovation productivity of expatriate researchers and human capital that empowers them is an important issue; however, with a scarcity of relevant data, formal empirical evidence has been limited. This paper uses a rich dataset of foreign researchers at a leading German research institution to study the drivers of their innovation productivity (measured by patents and invention disclosures). Anoth

Doing the rite thing

Denna artikel, som bygger på min avskedsföreläsning inför pensioneringen, visar lite av den mångfald av ingångar som finns i ritualstudiet. Oavsett om riter ändrar form och kontexter så är de formaliserade handlingarna centrala delar i individens liv eller samhället. Riten som begrepp och att hitta det rituella språket är viktigt i inom religionsämnet, men har oftast bortsetts till förmån för text

“Mocked by the Archon of Lust” : Panarion 1.26 and Epiphanius’ Hyperboles on Sex and Ascetics Read in Light of Fourth Century Ecclesiastical Debates

This article argues that the depictions of Gnostic sects performing horrendous rites in Epiphanius of Cyprus’ work Panarion worked as rhetorical devices to shift focus away from his own position vis-à-vis marriage, sex, and consumptions of good food and wine, a position that was considered liberal in the context of fourth century eccle- siastical debates. It here is shown how Epiphanius’ descripti

Prolargin and matrix metalloproteinase-2 in heart failure after heart transplantation and their association with haemodynamics

AIMS: Remodelling of the extracellular matrix (ECM) is a key mechanism involved in the development and progression of heart failure (HF) but also functional in associated pulmonary hypertension (PH). Our aim was to identify plasma ECM proteins associated to end-stage HF and secondary PH in relation to haemodynamics, before and after heart transplantation (HT).METHODS AND RESULTS: Twenty ECM plasma

Matrix metalloproteinase 7 in diagnosis and differentiation of pulmonary arterial hypertension

Pulmonary arterial hypertension is a severe disease for which diagnosis often is delayed. Matrix metalloproteinases have been suggested to play a role in vascular remodeling and pulmonary hypertension development. Our aim was therefore to investigate the potential role of matrix metalloproteinases as biomarkers in diagnosis and differentiation of pulmonary arterial hypertension in relation to vari

Pervaporation-based hybrid processes for waste water treatment: Does it have a future?

Pervaporation offers solutions for a wide range of applications ranging from the dehydration of organic compounds to the recovery of organic compounds from water and the separation of organic mixtures. While the combination of pervaporation and distillation in a hybrid process to break azeotropes is well established on an industrial scale, successful applications of hydrophobic pervaporation are r
