Features of Russian Agribusiness Grape-winery Subcomplex Modernization

The article devotes to the analysis of the Russian agribusiness grape-winery subcomplex current state and to its development features description. The problems of viticulture and winery, that impede the subcomplex development and modernization, are highlighted. These problems are the inability of viticulture farms to satisfy the wineries need for raw materials fully, the high cost of growing grapes, cheap imported wine materials, the lack of competitiveness towards foreign producers, and necessary financial support absence. To develop the wine and wine industry in our country, it is necessary to implement a set of measures at the federal and regional levels. At the federal level, it is necessary to create an appropriate legal framework for high-quality winemaking, which would equally protect the interests of grapes and wine producers, wine trading and consumers. At the regional level, it is relevant to improve the material and technical base state of the viticulture of Russia, because nowadays the industry development does not meet the existing agro technical requirements and lags significantly behind the development of Western countries. Since 2001, the state policy of supporting agricultural production conducted in the last decade and the agroindustrial policy in Russia in general has tended to create a developed wine-growing sub-complex. Over the past few years, when modernizing this subcomplex, vineyards have been renovated, new highly productive varieties have been laid. These measures positively affect the grape production and yield and generally give hope for the grape industry development. Emphasis is placed on key areas, features and prospects for the modernization of the wine and wine subcomplex of Russian agroindustrial complex. This is the implementation of a set of measures at the federal and regional levels. The article describes vectors and stages of the implementation of state policy and financial support in the field of this subcomplex modernization, proposed by the Concept of the Development of Viticulture and Winemaking in the Russian Federation for the period 2016–2020 and the planning period until 2025

FATTY ACID COMPOSITION OF LAMB MEAT FROM ITALIAN AND GERMAN LOCAL BREEDS

The aim of this study was to evaluate and compare the quality characteristics, chemical composition and lipid profile of lamb meat from Italian (Biellese and Sambucana) and German (Texel-Merino-Blackhead-Charollais [TMBC]) breeds reared in extensive and semi-extensive production systems. Meat samples from 89 animals were analysed. The meat of the lambs from semi-intensively reared Biellese, and extensively reared Sambucana and TMBC breeds produced lean meat, with slightly higher intramuscular fat content in TMBC. The latter also produced meat of darker colour (P<0.05) and higher protein content (P<0.05). The meat of Sambucana lambs presented the lowest total cholesterol content (P<0.05). The fatty acid profile of the meat showed a clear advantage of both extensively reared breeds, which had substantially lower proportion of saturated (SFA) but higher of polyunsaturated fatty acids (PUFA), particularly n-3 (P<0.05). The beneficial effect of the extensive rearing conditions was associated with lower n-6/n3 ratio, and atherogenic (AI) and thrombogenic (TI) indices, thereby suggesting that production system can be used successfully to modify the fatty acid profile to achieve a positive effect for the human health

Low energy excitations and dynamic Dzyaloshinskii-Moriya interaction in α′\alpha'-NaV2_2O5_5 studied by far infrared spectroscopy

We have studied far infrared transmission spectra of alpha'-NaV2O5 between 3 and 200cm-1 in polarizations of incident light parallel to a, b, and c crystallographic axes in magnetic fields up to 33T. The triplet origin of an excitation at 65.4cm-1 is revealed by splitting in the magnetic field. The magnitude of the spin gap at low temperatures is found to be magnetic field independent at least up to 33T. All other infrared-active transitions appearing below Tc are ascribed to zone-folded phonons. Two different dynamic Dzyaloshinskii-Moriya (DM) mechanisms have been discovered that contribute to the oscillator strength of the otherwise forbidden singlet to triplet transition. 1. The strongest singlet to triplet transition is an electric dipole transition where the polarization of the incident light's electric field is parallel to the ladder rungs, and is allowed by the dynamic DM interaction created by a high frequency optical a-axis phonon. 2. In the incident light polarization perpendicular to the ladder planes an enhancement of the singlet to triplet transition is observed when the applied magnetic field shifts the singlet to triplet resonance frequency to match the 68cm-1 c-axis phonon energy. The origin of this mechanism is the dynamic DM interaction created by the 68cm-1 c-axis optical phonon. The strength of the dynamic DM is calculated for both mechanisms using the presented theory.Comment: 21 pages, 22 figures. Version 2 with replaced fig. 18 were labels had been los

Lattice vibrations of alpha'-NaV2O5

We have measured far infrared reflectance and transmittance spectra as well as Raman scattering spectra of \alpha'-NaV2O5 single crystals for all the principal polarizations. The temperature range above the phase transition temperature T_c=35 K was investigated, mainly. On the basis of this experimental study and of the lattice dynamics calculations we conclude that the symmetry of NaV2O5 in the high temperature phase is described by the centrosymmetric D_{2h}^{13} space group. The assignment of the observed phonons is given. Values of dielectric constants are obtained from the infrared data. Asymmetric shapes of several infrared lines as well as higher order infrared vibrational spectra are discussed. The crystal field energy levels of the 3d electron localized at the V^{4+} site have been calculated in the framework of the exchange charge model using the values of effective charges obtained from the lattice dynamics calculations. According to the results of these calculations, the earlier observed broad optical bands in the region of 1 eV can be interpreted as phonon assisted d-d transitions.Comment: 12 pages, 8 figures, 5 tables; submitted to PR

Protuupalno i analgetsko djelovanje ekstrakta cijele biljke Fumaria indica na eksperimentalnim životinjama

The 50% ethanolic extract of Fumaria indica was investigated for its anti-inflammatory and antinociceptive potential in animal models. Oral administration of F. indica dry extract (100, 200 and 400 mg kg1) exhibited dose dependent and significant anti-inflammatory activity in acute (carrageenean and histamine induced hind paw oedema – p < 0.05) and chronic (cotton pellet granuloma models of inflammation – p < 0.01). The extract (400 mg kg1) exhibited maximum anti-inflammatory effects of 42.2 and 42.1% after 3 h with carrageenean and histamine respectively. The same dose of extract showed 38.9% reduction in granuloma mass in a chronic condition. A significant anti-nociceptive activity was evidenced in mice; 6.6–67.7% (p < 0.01) protection in mechanical, 33.9–125.1% (p < 0.05) protection in thermal induced pain and 22.2–73.9% (p < 0.05) protection in acetic acid-induced writhing.Na animalnom modelu ispitivano je protuupalno i analgetsko djelovanje ekstrakta biljke Fumaria indica sa 50%-tnim etanolnom.

Performance of the first prototype of the CALICE scintillator strip electromagnetic calorimeter

A first prototype of a scintillator strip-based electromagnetic calorimeter was built, consisting of 26 layers of tungsten absorber plates interleaved with planes of 45x10x3 mm3 plastic scintillator strips. Data were collected using a positron test beam at DESY with momenta between 1 and 6 GeV/c. The prototype's performance is presented in terms of the linearity and resolution of the energy measurement. These results represent an important milestone in the development of highly granular calorimeters using scintillator strip technology. This technology is being developed for a future linear collider experiment, aiming at the precise measurement of jet energies using particle flow techniques

Shower development of particles with momenta from 15 GeV to 150 GeV in the CALICE scintillator-tungsten hadronic calorimeter

We present a study of showers initiated by electrons, pions, kaons, and protons with momenta from 15 GeV to 150 GeV in the highly granular CALICE scintillator-tungsten analogue hadronic calorimeter. The data were recorded at the CERN Super Proton Synchrotron in 2011. The analysis includes measurements of the calorimeter response to each particle type as well as measurements of the energy resolution and studies of the longitudinal and radial shower development for selected particles. The results are compared to Geant4 simulations (version 9.6.p02). In the study of the energy resolution we include previously published data with beam momenta from 1 GeV to 10 GeV recorded at the CERN Proton Synchrotron in 2010.Comment: 35 pages, 21 figures, 8 table
