BaSeFood aims to promote sustainable development and exploitation of Traditional Foods containing emerging bioactive compounds with putative health effects in the Black Sea Region (BSR). The Consortium includes 13 partners covering the BSR, EuroFIR partners with experience on traditional foods and bioactive compounds at the pan-European level, and one representing 11 European Food and Drink Federations. The objectives of BaSeFood are: (1) To investigate the knowledge base of traditional foods of the BSR in order to identify those foods to be collected and analysed. (WP1). (2) To define, characterise and collect nutrient and bioactive data for a subset of about 30 prioritised traditional foods using previously developed and validated EuroFIR guidelines and bioactive databases, with appropriate analyses (WP2). (3) To carry out case human intervention studies (priority: cardiovascular disease protection), supported by intensive in vitro and in vivo laboratory tests, to address the requirement for supporting evidence in nutrition and health claims (WP3). (4) To accurately map and describe the flow charts of BSR traditional foods preparation and processing, and determine bioactive retention at both laboratory and pilot plant scale in close collaboration with industry partners (WP4). (5) To evaluate attitudes of processors and consumers in order to optimise and enhance the whole food chain for improved availability and health benefits of BSR traditional foods (WP5). (6) To widely disseminate results and findings in order to enhance awareness and sustainable development of traditional foods of the BSR for improved health (WP6). The project objectives are entirely congruent with those of the call, and will serve to (a) make a significant contribution to the substantiation of nutrition/health claims for traditional foods (b) enhance the cooperation between researchers and stakeholders, and (c) promote sustainable economic development for European SMEs and the BSR

Sandwiched structures of open-porous and solid polymer dielectrics reveal a strong piezoelectric response after proper charging by high electric fields. Here, the electrical properties of corona-poled three-layer FEP/ePTFE/FEP sandwiches are studied theoretically and experimentally with the objective of its possible optimization for the highest piezoelectric activity. Modelling of the charging properties is performed for different sandwich geometries. It is shown that the maximum value of the remanent interface charge density accumulated during poling depends mainly on the ratio of the solid and porous layers thicknesses and on parameter E B, which characterizes the electric breakdown strength of air in the porous layer. E B exhibits specific dependences on porosity and thickness of the porous layer. For a given porous layer E B is independent of the solid film thickness. The obtained results can be utilized to further optimize the sandwich structure as an electromechanically active device. © 2011 IOP Publishing Ltd.

Benchmarking | Year: 2011

Purpose: The paper aims to focus on improving the methodology and developing the model of choice of optimal investment object using benchmarking tools that eliminate the drawbacks of existing approaches. Design/methodology/approach: The methodological basis of the proposed model is frontier analysis, namely the nonparametric data envelopment analysis. Using this and other benchmarking tools, the author introduces the concept and mathematical model for evaluation of super-attractiveness for investors that allows a full ranking of potential objects for investment. Findings: The concept of variable investment decision that combines various periods, varying degrees of risk and other decision characteristics with a common purpose of maximizing the benefits from investments is defined. The model for the making of variable investment decisions is developed. Practical implications: The proposed model enables strategic and portfolio investors to implement the optimal choice of investment object. It is demonstrated on a case of the food production of Ukraine. Originality/value: This paper adopts benchmarking tools to the decision-making process to optimal choice of investment object. © Emerald Group Publishing Limited.

Physics of Metals and Metallography | Year: 2015

The three-particle interaction of protons in metallic hydrogen has been investigated in detail for the first time. It has been shown that this interaction is determined by the third-order perturbation-theory term in the potential of the electron-proton interaction for the energy of conduction electrons in the field of protons. It has been shown that the three-particle interaction for the majority of configurations of protons is small compared to the effective pairwise interaction, but for some configurations, it significantly exceeds the latter. It follows from the calculations performed that the three-particle interaction tends to compress hydrogen to larger densities than those produced by the pairwise effective interaction. The maximum depth of the potential well for the three-particle interaction of protons corresponds to the location of protons on a common straight line, which can be interpreted as a tendency to the formation of a cubic lattice in the metallic state. The liquid-metal state of hydrogen can be stable at temperatures that significantly exceed room temperature. The three-particle interaction also favors the transition of hydrogen into an atomic state as an intermediate state between its molecular and metallic phases. © 2015, Pleiades Publishing, Ltd.

Fluid Phase Equilibria | Year: 2014

The typical treatment of the small-angle X-ray scattering (SAXS) experiment for supercritical fluids contains two interconnected uncertainties. One supposes a priori an unimodal, Gaussian-type distribution of local density for any volumes of observation in spite of its strong fluctuations near and above the actual critical point. Accordingly, the empirical or semitheoretical unified equations of state (EOS) are used to normalize the SAXS-intensities which cannot express the singular behavior of the isothermal compressibility and, as a result, cannot predict adequately the Ornstein-Zernike (OZ) correlation length. On the other hand, the numerical molecular-dynamical (MD) experiment in a combination with the coarse-graining analysis reveals the typically bimodal structure of a compressible fluid regime in the supercritical region if one takes into account not only the aggregates of particles with the augmented average density but also the steady existence of "voids" with its depletion. To reconcile qualitatively laboratory SAXS- and numerical MD-experiments the methodology of global fluid asymmetry (GFA) proposed by authors in the framework of FT-(fluctuational thermodynamics) model has been used in this work. In particular, the known problem of a "ridge" formed by the supposedly Gaussian distributions of the isothermal density fluctuations is reformulated in terms of their presumably bimodal structure. Its location below the critical isochore in the P,. T-diagram found by the traditional SAXS-treatment is independently confirmed only for the liquid like peak of supercritical distribution while the additional, predicted here gas like peak is definitely located at the lower densities. The both peaks of such thin structure revealed in the density fluctuations coincide at the pseudocritical (but non-mean-field) point where the distributions of any thermodynamic densities become indeed Gaussian ones at the higher temperatures and pressures of a ridge. The phenomenological generalization of the OZ-theory based on the FT/GFA-approach is formulated in terms of the finite-range direct and total correlation integrals. © 2014 Published by Elsevier B.V.

Milling is the physical process of converting the endosperm of wheat kernel into flour. The first stage of the modern flour milling process is the break system, in which the wheat kernel is opened up and the contents released so that the endosperm may be separated from the bran. The aim of the study presented in this paper was to investigate effect of various structures of the head break system on the yield and ash content of the streams from the three break systems at the laboratory mill. The conventional milling break system (A), the break system with double high roller mills at B1 and B2 (B), the break system with debranning pre-treatment (C) and the break system with pre-break as a pre-treatment (D), at the similar break release on B1 and B2 were compared. The lower coarse fraction (through 1000-μ and over 630-μ) yield, higher yield of other streams, higher ash content of common streams from three break systems and higher energy requirements for grinding has been obtained using double high roller mill. In the opposite of that grinding with debranning pretreatment led to increase in coarse fraction yield, decrease in small fractions yield (including break flour yield) and decrease in energy requirements for grinding but ash content of common streams was close to the ones using double rollermill and was higher compared to conventional break system. The most effective break system structure was grinding with pre-break system pre-treatment (3-5% break release through 1000-μ) in which yield of all fractions was close to conventional break system, but with insignificantly lower ash content of all fractions and energy requirements for grinding.

The Sturm-Liouville equations on the edges of a metric connected graph together with the boundary and matching conditions at the vertices generate a spectral problem for a self-adjoint operator. It is shown that if the graph is not cyclically connected, then the maximal multiplicity of an eigenvalue of such an operator is μ + gT - pin T, where μ is the cyclomatic number of the graph, and gT and pT in are the number of edges and the number of interior vertices, respectively, for the tree obtained by contracting all the cycles of the graph into vertices. If the graph is cyclically connected, then the maximal multiplicity of an eigenvalue is μ + 1. © 2011 IOP Publishing Ltd.
