A general formula for noncohesive suspended sediment transport

A simple and robust suspended load transport formula for noncohesive sediment is presented for application to river, estuarine, and coastal environments with the use of depth-averaged models. The formula is based on an exponential profile for the concentration and assumes a constant velocity over depth to simplify the calculations. These assumptions were validated with a large data set, including

Is the commercialization of European academic R&D weak?-A critical assessment of a dominant belief and associated policy responses

There is a widespread belief that EU underperforms in the commercialization of publicly funded research and that the appropriate policy response is to transfer the ownership of intellectual property rights to Universities. This paper assesses the validity of these twin beliefs. In addressing the first, we limit ourselves to Sweden which still retains its "Teacher's Exemption" model. In spite of co

Terrestrial organic matter support of lake food webs : evidence from lake metabolism and stable hydrogen isotopes of consumers

We quantified the utilization of terrestrial organic matter (OM) in the food web of a humic lake by analyzing the metabolism and the consumers' stable isotopic (C, H, N) composition in benthic and pelagic habitats. Terrestrial OM inputs (3 g C m(-2) d(-1)) to the lake greatly exceeded autochthonous OM production (3 mg C m(-2) d(-1)) in the lake. Heterotrophic bacterial growth (19 mg C m(-2) d(-1))

MOVPE Growth and Structural Characterization of Extremely Lattice-Mismatched InP-InSB Nanowire Heterostructures

We present a growth study and structural characterization of InP-InSb nanowire heterostructures. In contrast to planar epitaxy, this heterostructure can be realized in nanowires without the formation of dislocations, despite an extreme lattice-mismatch (10.4%). We obtain high crystal quality in the InSb nanowires, confirmed by a narrow 111 reflection peak measured by XRD. Additionally, the diamete

Umbilical cord plasma levels of growth-arrest specific protein 6 in intrauterine growth restriction

Objective. Growth arrest specific protein 6 (GAS6) is a newly discovered antiapoptotic protein related to cell survival. We hypothesized that GAS6 might be involved in the fetal adaptation to intrauterine growth restriction (IUGR). Design. A nested case-control study. Setting. A retrospective study of 25 small-for-gestational age and 36 appropriate-for-gestational age pregnancies. Sample. Frozen s

Climatology of the Iberia coastal low-level wind jet: weather research forecasting model high-resolution results

Coastal low-level jets (CLLJ) are a low-tropospheric wind feature driven by the pressure gradient produced by a sharp contrast between high temperatures over land and lower temperatures over the sea. This contrast between the cold ocean and the warm land in the summer is intensified by the impact of the coastal parallel winds on the ocean generating upwelling currents, sharpening the temperature g

Presence of High-Risk HPV mRNA in Relation to Future High-Grade Lesions among High-Risk HPV DNA Positive Women with Minor Cytological Abnormalities.

Continuous expression of E6- and E7-oncogenes of high-risk human papillomavirus (HPV) types is necessary for the development and maintenance of the dysplastic phenotype. The aim of the study was to determine the sensitivity and specificity of the APTIMA HPV mRNA assay (Hologic) in predicting future development of high-grade cervical intraepithelial neoplasia (CIN) among high-risk HPV-DNA-positive

Contributions to the knowledge of Caloplaca in the Nordic countries

The genus Caloplaca in the Nordic countries is currently under revision and this work has resulted in a number of new records for the Nordic countries or provinces within the countries. These records are presented here. Caloplaca arnoldii subsp. arnoldii is reported new to Sweden, C. conciliascens new to Norway and Sweden, C. castellana new to Finland, C. hungarica new to Norway and Sweden, C. isi

Temporal and spatial effects inside a compact and CEP stabilized, few-cycle OPCPA system at high repetition rates

We present a compact and ultra-stable few-cycle OPCPA system. In two non-collinear parametric amplification stages pulse energies up to 17 mu J at 200 kHz repetition rate are obtained. Recompression of the broadband pulses down to 6.3 fs is performed with chirped mirrors leading to peak powers above 800 MW. The parametric amplification processes were studied in detail employing (2 + 1) dimensional

Electromagnetic field enhancement in TERS configurations

We use three-dimensional finite-difference time domain (3D-FDTD) simulations to investigate the field enhancement properties of tip-enhanced Raman scattering (TIERS) in order to find optimal geometric parameters of the metal tip and the metal substrate under certain excitation wavelengths with side illumination. The simulation results show that plasmon coupling effects between the metal tip and th

Design and technical construction of a tactile display for sensory feedback in a hand prosthesis system

Background: The users of today's commercial prosthetic hands are not given any conscious sensory feedback. To overcome this deficiency in prosthetic hands we have recently proposed a sensory feedback system utilising a "tactile display" on the remaining amputation residual limb acting as man-machine interface. Our system uses the recorded pressure in a hand prosthesis and feeds back this pressure
