The European species of Foersterella Dalla Torre (Hymenoptera : Tetracampidae), including the description of two new species

The European species of Foersterella Dalla Torre 1897 (Hymenoptera: Tetracampidae) are treated, including two previ-ously described species, F. erdoesi Bouček and F. reptans (Nees), and two new species, F. angusticornis sp. nov. and F. fuscicornis sp. nov. Morphological concepts of the species are based mainly on characters in the male antenna, which fe-males lack, and with the exception of F. erd

Tundra meets atmosphere : Seasonal dynamics of trace gas exchange in the High Arctic

Arktiska miljöer har de senaste decennierna upplevt en stark temperaturökning, vilket påverkar tundrans kolcykel.Smältande permafrost, minskande snötäcke och förändringar i hydrologiska mönster är exempel på pågående processer som förändrar samspelet mellan mark och atmosfär samt ekosystemens säsongsdynamik.Då ett antal av dessa processer involverar utbyte av växthusgaser, såsom spårgaserna metan Arctic environments have experienced strong warming in recent decades, which is affecting the carbon cycle of tundra ecosystems.Degrading permafrost, diminishing snow cover, and changing hydrology are examples of ongoing processes that affect the land-atmosphere interactions and seasonal ecosystem dynamics.Since a number of the affected processes involve the exchange of atmospheric greenhouse gase

Sponges of the family Axinellidae (Porifera : Demospongiae) in Indonesia

Nine species in five genera of the family Axinellidae, including three new species, Axinella badungensis sp. nov., A. ba-linensis sp. nov. and Phycopsis pesgalli sp. nov. are recorded from Indonesian waters within the limits of the Western Coral Triangle province. Descriptions and discussion of those species are presented here. Four new combinations, Pha-kettia arbora (Sim, Kim & Byeon, 1990)

Water-Mediated Ion Pairing : Occurrence and Relevance

We present an overview of the studies of ion pairing in aqueous media of the past decade. In these studies, interactions between ions, and between ions and water, are investigated with relatively novel approaches, including dielectric relaxation spectroscopy, far-infrared (terahertz) absorption spectroscopy, femtosecond mid-infrared spectroscopy, and X-ray spectroscopy and scattering, as well as m

Type and quantity of organic amendments determine the amount of carbon stabilized in particle-size fractions of a semiarid degraded soil

A 9-month lab experiment was carried out with three different amendments (vine pruning wastes, PW; composted vine pruning wastes, cPW; and sewage sludge, SS) added at three different rates (90, 180, and 240 t ha−1, dry weight) in order to test whether the type or the quantity of the amendments applied to a semiarid, degraded soil determined the Corg accumulation in its particle-size fractions (coa

Cardiometabolic biomarkers are predictors of readmission and death in patients hospitalized for acute dyspnea

BACKGROUND: Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.PURPOSE: To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.METHODS: 65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission

Two years with extreme and little snowfall : Effects on energy partitioning and surface energy exchange in a high-Arctic tundra ecosystem

Snow cover is one of the key factors controlling Arctic ecosystem functioning and productivity. In this study we assess the impact of strong variability in snow accumulation during 2 subsequent years (2013-2014) on the land-atmosphere interactions and surface energy exchange in two high-Arctic tundra ecosystems (wet fen and dry heath) in Zackenberg, Northeast Greenland. We observed that record-low

Surface Partitioning in Organic-Inorganic Mixtures Contributes to the Size-Dependence of the Phase-State of Atmospheric Nanoparticles

Atmospheric particulate matter is one of the main factors governing the Earth's radiative budget, but its exact effects on the global climate are still uncertain. Knowledge on the molecular-scale surface phenomena as well as interactions between atmospheric organic and inorganic compounds is necessary for understanding the role of airborne nanoparticles in the Earth system. In this work, surface c

Amylin alters human brain pericyte viability and NG2 expression

Amylin, a pancreatic β-cell-derived peptide hormone, forms inclusions in brain microvessels of patients with dementia who have been diagnosed with type 2 diabetes and Alzheimer's disease. The cellular localization of these inclusions and the consequences thereof are not yet known. Using immunohistochemical staining of hippocampus and parahippocampal cortex from patients with Alzheimer's disease an

Risk assessment of oil price from static and dynamic modelling approaches

The price gap between West Texas Intermediate (WTI) and Brent crude oil markets has been completely changed in the past several years. The price of WTI was always a little larger than that of Brent for a long time. However, the price of WTI has been surpassed by that of Brent since 2011. The new market circumstances and volatility of oil price require a comprehensive re-estimation of risk. Therefo

Measuring motivation using the transtheoretical (stages of change) model : A follow-up study of people who failed an online hearing screening

Abstract: Objective: Acceptance and readiness to seek professional help have shown to be important factors for favourable audiological rehabilitation outcomes. Theories from health psychology such as the transtheoretical (stages-of-change) model could help understand behavioural change in people with hearing impairment. In recent studies, the University of Rhode Island change assessment (URICA) ha

Comparison of risk assessment based on clinical judgement and Cariogram in addition to patient perceived treatment need

Background: Predicting future risk for oral diseases, treatment need and prognosis are tasks performed daily in clinical practice. A large variety of methods have been reported, ranging from clinical judgement or "gut feeling" or even patient interviewing, to complex assessments of combinations of known risk factors. In clinical practice, there is an ongoing continuous search for less complicated

Dissemination of research results from Lund University to industry and society

Sweden is top ranked as the third most innovative nation in the world according to Global Innovation Index 2015. The academic staff at Swedish universities has the right to their inventions (research-ownership of patent rights) as opposed to far more diffuse university-ownership. Since 1977 the Swedish Higher Education Act imposes Swedish universities a so-called Third task. In addition to educati

Engaging local industry in the development of basic research infrastructure and instrumentation - The case of HIE-ISOLDE and ESS Scandinavia

Two world-class research facilities, the European Spallation Source, ESS, and the light-source facility MAX-IV, are being built in southern Sweden. They will primarily, when completed, be used for research in the fields of material sciences, life sciences, medicine and pharmacology. Their construction and the operation and maintenance of them for many years will create new business opportunities f

Portal Stability Controls Dynamics of DNA Ejection from Phage

Through a unique combination of time-resolved single-molecule (cryo-TEM) and bulk measurements (light scattering and small-angle X-ray scattering), we provide a detailed study of the dynamics of stochastic DNA ejection events from phage λ. We reveal that both binding with the specific phage receptor, LamB, and thermo-mechanical destabilization of the portal vertex on the capsid are required for in

Exclusive vector meson production with a leading neutron in photon-hadron interactions at hadronic colliders

In this paper, we study leading neutron production in photon-hadron interactions that take place in pp and pA collisions at large impact parameters. Using a model that describes the recent leading neutron data at HERA, we consider exclusive vector meson production in association with a leading neutron in pp/pA collisions at RHIC and LHC energies. The total cross sections and rapidity distributions
