Flyttning hos grågäss enligt återfynd av fåglar märkta med traditionella metallringar i Sverige

Traditional recoveries of ringed Greylag Geese Anser anser from different regions in Sweden have been analyzed to compare the migration patterns from a number of different areas. During the years up to and including 2012, 7210 Greylag Geese were marked with metal rings from the Swedish Ringing Centre, yielding 1398 recoveries. After exclusion of local recoveries in the ringing area, 924 recoveries

Changes in local distribution and numbers of staging and wintering bean geese anser fabalis in scania, south Sweden 1977/1978–2016/2017

Scania in southern Sweden is an important staging and wintering province for the Bean Goose Anser fabalis, especially for the Taiga form A. f. fabalis. Based on counts in October, November and January 1977/1978– 2016/2017, and observations of neck-banded individuals, the changes in local distribution are described. When the counts started, large numbers were counted already in October, but autumn

Green warbler phylloscopus nitidus ringed at blåvand : Molecular confirmation of a Danish first and European eighth vagrant record

On 27 May 2015, a Green Warbler Phylloscopus nitidus was caught and ringed at Blåvand Bird Observatory, the westernmost point in Denmark. The species is challenging to identify on morphological basis alone, and the bird’s identity was confirmed with phylogenetic analyses of mitochondrial DNA sequences. This constitutes the first record of Green Warbler in Denmark, the third record in Fennoscandia

Hypertonic Saline Infusion Acutely Degrades Mood in Healthy Volunteers (P23-014-19)

Objectives: Mild and moderate dehydration adversely affect mood and cognitive function. During dehydration, hypertonic hypovolemia activates both osmo- and baro-receptors but it is not known which physiological pathway is associated with degraded mood state. This study examined the acute effect of osmoreceptor stimulation on mood.Methods: Sixty healthy adults (50% females, 30 ± 1 y; BMI: 26.9 ± 4.

On the proper interpretation of nanofluid convective heat transfer

Technological developments of the last decades allow the production and the dispersion of particles of sizes ranging between 10 and 100 nm in liquids. In a large number of recent studies the resulting nanofluids have been reported to display anomalously high increase in convective heat transfer. The present study compiles experiments from five independent research teams investigating convective he

Simulation of heat transfer in the contact line region of pure pentane and pentane/hexane mixture in a closed microcavity

Understanding the heat transfer characteristics in the three-phase contact line region has great significance in achieving efficient evaporation/condensation. Phase change becomes especially complicated when a fluid mixture is used. The dynamics of phase change heat and mass transfer in the three-phase contact line region of binary fluid is still not clear. Based on the volume of fluid (VOF) model

Pressure fluctuations of liquid-liquid slug flow in cross-junction square microchannels

Microchannels are widely used for heat transfer enhancement. The pressure characteristics are one of the most important factors affecting the heat transfer performance, and the pressure regulation may also control the heat transfer precisely in turn. As a common flow pattern of two-phase flow, slug flow has obvious advantages for heat and mass transfer, like steady flow rate and large interface ar

Investigation of heat transfer and fluid flow in fractal truncated ribbed channels for the internal cooling of turbine blades

Ribs are widely employed in internal cooling passages of turbine blades to enhance heat transfer. From the mathematics, a fractal is an abstract object used to describe naturally occurring objects which exhibits similar properties with increased smaller scales. In a ribbed channel, originating from two sides truncated ribs, fractal truncated ribs are built and the evolving process contains three s

Experimental investigation of heat transfer enhancement on the endwall around an obstacle embedded with a vortex generator pair

Heat transfer enhancement on the endwall around an obstacle embedded with a pair of vortex generators is investigated. Obstacles with cylindrical and square cross sections are experimentally examined and compared with and without vortex generators. The vortex generators employed is a pair of longitudinal winglet vortex generator. Local Nusselt numbers are calculated for both types of obstacles in

Enhancement of HFE-7200 pool boiling heat transfer on copper surfaces with nanoparticle coatings

Saturated pool boiling heat transfer of HFE-7200 is investigated experimentally on copper surfaces with nanoparticle coatings at atmospheric pressure. The coatings are generated by an electrophoretic deposition method. Two modified surfaces are prepared with Cu-Zinc nanoparticles of 0.3 mg and 0.6 mg, respectively. During the deposition, ethanol works as the solvent while the electrical potential

Incretin-based medications (GLP-1 receptor agonists, DPP-4 inhibitors) as a means to avoid hypoglycaemic episodes

Hypoglycaemia is common in both type 1 and type 2 diabetes and has both acute and long-term consequences. Therefore, a key to proper glucose-lowering therapy in diabetes is to avoid or prevent hypoglycaemia. Incretin therapy (DPP-4 inhibitors and GLP-1 receptor agonists) offers an advantage in this respect, because it reduces glucose with a low risk of hypoglycaemia, both in monotherapy and in com

Stabilization of a turbulent premixed flame by a plasma filament

The mechanism of stabilizing a turbulent premixed methane-air flame using warm filamentary plasma is investigated by using laser diagnostics. First, stabilization of a turbulent jet flame is demonstrated in a setup using a pin-to-pin plasma discharge. The coupled plasma-flame structures were visualized utilizing planar laser-induced fluorescence (PLIF) of formaldehyde (CH2O) and methylidyne radica

Heat transfer prediction and critical heat flux mechanism for pool boiling of NOVEC-649 on microporous copper surfaces

Pool boiling performance of NOVEC-649 was experimentally studied on microporous surfaces prepared by an electrochemical deposition method. Microporous structures contribute to large surface roughness values and provide large quantities of cavities ranging from several hundreds of nanometers to several microns for bubble nucleation. The results show that a maximum enhancement of 600% in heat transf

Trends of land surface phenology derived from passive microwave and optical remote sensing systems and associated drivers across the dry tropics 1992–2012

Changes in vegetation phenology are among the most sensitive biological responses to global change. While land surface phenological changes in the Northern Hemisphere have been extensively studied from the widely used long-term AVHRR (Advanced Very High Resolution Radiometer) data, current knowledge on land surface phenological trends and the associated drivers remains uncertain for the tropics. T

Tailored reduced kinetic mechanisms for atmospheric chemistry modeling

Reduced chemical kinetic mechanisms are essential for atmospheric chemistry modeling where the use of explicit kinetic schemes is too computationally demanding. By tailoring mechanisms to specific cases, the size of the mechanism can be kept small, without significant loss of accuracy in predictions of selected species’ concentrations. In the present work, we present small kinetic mechanisms tailo

Most gene fusions in cancer are stochastic events

Cancer-associated gene fusions resulting in chimeric proteins or aberrant expression of one or both partner genes are pathogenetically and clinically important in several hematologic malignancies and solid tumors. Since the advent of different types of massively parallel sequencing (MPS), the number of identified gene fusions has increased dramatically, prompting the question whether they all have
