The impact of catch-and-release on the foraging behaviour of pike (Esox lucius) when released alone or into groups

A commonly practiced method intended to reduce mortality from recreational fisheries is mandatory (e.g., small fish protected by minimum-size limits) or voluntary catch-and-release (C&R), where fish are caught with hook and line and released alive on the assumption that fish survive unharmed. C&R can, however, have both lethal and sub-lethal consequences for fish, with altered behaviour se

Accelerating crystal plasticity simulations using GPU multiprocessors

Crystal plasticity models are often used to model the deformation behavior of polycrystalline materials. One major drawback with such models is that they are computationally very demanding. Adopting the common Taylor assumption requires calculation of the response of several hundreds of individual grains to obtain the stress in a single integration point in the overlying FEM structure. However, a

Smoking and the risk of prostate cancer in the European Prospective Investigation into Cancer and Nutrition

Background: Smoking is not associated with prostate cancer incidence in most studies, but associations between smoking and fatal prostate cancer have been reported. Methods: During 1992 and 2000, lifestyle information was assessed via questionnaires and personal interview in a cohort of 145112 European men. Until 2009, 4623 incident cases of prostate cancer were identified, including 1517 cases of

The role of entrepreneurship education and start-up experience for handling communication and liability of newness

Purpose – The aim of this study is to test the assumption that ability to handle communication and liability of newness (LoN) is enhanced by academic entrepreneurship education and/or previous start‐up experience. Design/methodology/approach – The data collection includes a questionnaire with a total sample of 392 responding entrepreneurs in Sweden. Statistical analyses are made between entrepren

Zero, one, or in between : Evaluation of alternative national and entity-level accounting for bioenergy

Accounting for bioenergy's carbon dioxide (CO2) emissions, as done under the Kyoto Protocol (KP) and European Union (EU) Emissions Trading Scheme, fails to capture the full extent of these emissions. As a consequence, other approaches have been suggested. Both the EU and United States already use value-chain approaches to determine emissions due to biofuels - an approach quite different from that

Near-infrared spectroscopy for intracoronary detection of lipid-rich plaques to understand atherosclerotic plaque biology in man and guide clinical therapy.

Ischaemic heart disease is the leading cause of death worldwide. The common denominator for plaques causing acute coronary syndrome (ACS) is lipid accumulation, either as a lipid core or lipid pools. An intracoronary imaging device to detect lipid-rich plaques (LRPs) could therefore identify most of the plaques causing ACS and sudden death. Near-infrared spectroscopy combined with intravascular ul

High frequency ultrasound of skin involvement in systemic sclerosis - a follow-up study.

High-frequency ultrasound offers a potential for objective and quantitative assessment of skin thickness and skin echogenicity in systemic sclerosis (SSc). Few studies have however assessed the longitudinal changes of skin involvement using ultrasound. The aim of the study was to investigate changes in skin thickness in early SSc using high frequency ultrasound during one year of follow-up in comp

Evaluating the Machinability of Inconel 718 Using Polar Diagrams

Abstract in UndeterminedThe use of a polar diagram method for describing and evaluating the machinability ofInconel 718 was explored. Five key parameters of the work material, representing themechanical and physical properties, which have the strongest influence on its machinability,were employed in the diagrams. These five parameters were integrated into asingle polar diagram, used to describe th

The Influence of Sea Waves on Offshore Wind Turbine Aerodynamics

The impacts of swells on the atmospheric boundary layer (ABL) flows and by this on the standalone offshore wind turbine (WT) performance are investigated by using large eddy simulations (LES) and actuator-line techniques. At high swell to wind speed ratio, the swell-induced stress reduces the total wind stress resulting in higher wind velocity, less wind shear, and lower turbulence intensity level

Moving beyond short-term coping and adaptation

Throughout human history, people have coped with, and adapted to, their environment. This accumulated capacity at local level is increasingly recognized to be critical in improving resilience and transformation. Nevertheless, city dwellers’ coping and adaptive practices are little known, poorly documented and often not taken into account in the work of municipal authorities and aid organizations.

Sorting cells by size, shape and deformability.

While size has been widely used as a parameter in cellular separations, in this communication we show how shape and deformability, a mainly untapped source of specificity in preparative and analytical microfluidic devices can be measured and used to separate cells.

Anaerobic digestion of industrial hemp-Effect of harvest time on methane energy yield per hectare

There is a worldwide emphasis to increase the share of renewable transportation fuels. When using agricultural land for production of renewable transportation fuels, the energy output per hectare for different crops and transportation fuels is a crucial factor. In this study, the gross methane energy yield per hectare from anaerobic digestion of industrial hemp (Cannabis sativa L.), was determined

Traits of a representative welfare model - The Swedish example

The care manager reform and the case manager reform are new reforms in the social care services in Sweden, which are evolving during the 2000s. Together they shape the social care services introducing a new way of decision-making where representatives for the organisation (care manager) and the users (case manager) negotiate. The reforms have been analysed in two studies with results presented in

The Employment Contract Revisited.

This article considers recent legal developments on undocumented migrant workers, finds the acceptance of international legal standards unsatisfactory and argues that the private law rights derived from the "semi-legal" employment contract between the employer and the undocumented migrant worker generates a solid base for significant legal claims. It further monitors the promotion of the position

A longitudinal study of semantic memory impairment in patients with Alzheimer's disease

Introduction: The present study explored the nature of the semantic deterioration normally displayed in the course of Alzheimer's disease (AD). The aim was to disentangle the extent to which semantic memory problems in patients with AD are best characterized as loss of semantic knowledge rather than difficulties in accessing semantic knowledge. Method: A longitudinal approach was applied. The same

Revisiting factors controlling methane emissions from high-Arctic tundra

The northern latitudes are experiencing disproportionate warming relative to the mid-latitudes, and there is growing concern about feedbacks between this warming and methane production and release from high-latitude soils. Studies of methane emissions carried out in the Arctic, particularly those with measurements made outside the growing season, are underrepresented in the literature. Here we pre

MicroRNA changes in human arterial endothelial cells with senescence: Relation to apoptosis, eNOS and inflammation

A senescent phenotype in endothelial cells is associated with increased apoptosis, reduced endothelial nitric oxide synthase (eNOS) and inflammation, which are implicated in arterial dysfunction and disease in humans. We tested the hypothesis that changes in microRNAs are associated with a senescent phenotype in human aortic endothelial cells (HAEC). Compared with early-passage HAEC, late-passage
