Green Synthesis and Characterization of Gold and Silver Nanoparticles and their Application for Development of a Third Generation Lactose Biosensor

In this paper we report on a facile, cost effective and environmental friendly green synthesis method of gold and silver nanoparticles (NPs) by using quercetin as reducing agent. The obtained NPs were characterized by transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), dynamic light scattering (DLS) and UV-Vis spectroscopy and parameters such as pH, ionic strength and tem

Monitoring Nanostructure Dynamics and Polymerization in Glycerol Plasticized Wheat Gliadin and Glutenin Films : Relation to Mechanical Properties

Gliadin and glutenin proteins with 10, 20, 30 and 40% of glycerol were compression molded into films (130 °C) and evaluated for protein polymerization, β-sheet structure and nano-structural morphology. Here, for the first time we show how different amounts of glycerol impact the nano-structure and functional properties of the gliadin and glutenin films. Most polymerized protein was found in the gl

Application of full-reference video quality metrics in IPTV

Executing an accurate full-reference metric such as VQM can take minutes in an average computer for just one user. Therefore, it can be unfeasible to analyze all the videos received by users in an IPTV network for example consisting of 10.000 users using a single computer running the VQM metric. One solution can be to use a lightweight no-reference metrics in addition to the full-reference metric

Breit and QED effects on the 3d9 D3/2 2 →2D5/2 transition energy in Co-like ions

The multiconfiguration Dirac-Hartree-Fock theory is used to calculate the 3d9D3/22→2D5/2 transition energy for Co-like ions with Z=28-100. We investigate how electron correlation, frequency-independent and -dependent Breit interactions, as well as QED corrections vary along the sequence. The well-understood frequency-independent Breit contribution has the largest contribution for all ions. Among t

Technical safety barrier management in StatoilHydro

The Norwegian Offshore Regulator requires top executives to confirm the safety of their installations with particular focus on established barriers towards large scale accidents. StatoilHydro has implemented a structured approach for assessing the technical safety condition of its key barriers. Performance Standards (PS's) are defined for each barrier and each PS defines a set of Performance Requi

New Clean Energy Communities in a Changing European Energy System (NEWCOMERS) : Deliverable D3.1 Description of polycentric settings in the partner countries

This deliverable maps the prevailing polycentric settings of six studied countries. The studied countries are the partner countries for the NEWCOMERS project, i.e. Germany, Italy, the Netherlands, Slovenia, Sweden and the United Kingdom. In this report, the countries' polycentric settings will be described in relation to the polycentric framework developed in WP 2, with specific focus on the techn

Food hoarding

Many animals store food outside of their own bodies for later consumption, not only birds and mammals, but also invertebrates such as honeybees. I refer to such food storage as hoarding, to distinguish it from internal storage such as in fat deposits. There are two distinct food-hoarding strategies: larder hoarding (all food is stored in one or a few central larders) and scatter hoarding (storage

Mammogram synthesis using a 3D simulation. II. Evaluation of synthetic mammogram texture

We have evaluated a method for synthesizing mammograms by comparing the texture of clinical and synthetic mammograms. The synthesis algorithm is based upon simulations of breast tissue and the mammographic imaging process. Mammogram texture was synthesized by projections of simulated adipose tissue compartments. It was hypothesized that the synthetic and clinical texture have similar properties, a

Fixed Effects Demeaning in the Presence of Interactive Effects in Treatment Effects Regressions and Elsewhere

The present paper shows that cross‐section demeaning with respect to time fixed effects is more useful than commonly appreciated, in that it enables consistent and asymptotically normal estimation of interactive effects models with heterogeneous slope coefficients when the number of time periods, T , is small and only the number of cross‐sectional units, N , is large. This is important when using

Hybrid FeNiOOH/α-Fe2O3/Graphene Photoelectrodes with Advanced Water Oxidation Performance

In this study, the photoelectrochemical behavior of electrodeposited FeNiOOH/Fe2O3/graphene nanohybrid electrodes is investigated, which has precisely controlled structure and composition. The photoelectrode assembly is designed in a bioinspired manner where each component has its own function: Fe2O3 is responsible for the absorption of light, the graphene framework for proper charge carrier trans

Computational Atomic Structure: Applications to Astrophysics and Nuclear Structure

This thesis deals with the modelling of atoms and ions. In heavy systems, where the effect of the nuclear size must be considered, a fully relativistic treatment based on the Dirac-Coulomb Hamiltonian is needed. Chapter two of the thesis provides an introduction to the basic principles of the fully relativistic multiconfiguration Dirac-Hartree-Fock (MCDHF) method, which is a variational approach f

Quality Improvement Initiatives in Fragility Fracture Care and Prevention

Purpose of Review: This review sought to describe quality improvement initiatives in fragility fracture care and prevention. Recent Findings: A major care gap persists throughout the world in the secondary prevention of fragility fractures. Systematic reviews have confirmed that the Fracture Liaison Service (FLS) model of care is associated with significant improvements in rates of bone mineral de

Statistical model fitting and model selection in pedestrian dynamics research

Pedestrian dynamics is concerned with understanding the movement patterns that arise in places where more than one person walks. Relating theoretical models to data is a crucial goal of research in this field. Statistical model fitting and model selection are a suitable approach to this problem and here we review the concepts and literature related to this methodology in the context of pedestrian

Decision-making process for addressing bottleneck problems in district heating networks

Lower system temperatures in district heating (DH) grids are important factors for system efficiency. Lower system temperatures lead, for example, to lower heat losses and higher production unit efficiency. One obstacle to lower supply temperatures are so-called bottlenecks in DH networks. Bottlenecks are areas in DH networks of very low differential pressure, which makes it difficult to supply th

Photo-reactivity of dissolved organic carbon in the freshwater continuum

The patterns in dissolved organic carbon (DOC) photo-mineralization along the freshwater continuum from land to sea are poorly known. Specifically, it has not been resolved how the photo-degradation of DOC into CO2 (PD) depends on the combination of intrinsic properties of DOC and extrinsic variables that affect the photo-reactions. We measured PD per unit of absorbed ultraviolet light energy (PD-
