The Study of Changes in the Structural and Mechanical Properties of Turkey Fillet During Storage

The method and equipment for the study of changes of structural-mechanical properties of Turkey fillet at storage were offered. The improved express-method of the study allows determine the relaxation effort and time at axial deformation and the firmness limit of meat fibers using penetration.The selection of registering equipment and sensors for the study of structural-mechanical properties of Turkey fillet was grounded. The methods of compensation of axial displacement of sensors at the study of penetration and relaxation were described. The principal scheme, appearance and example of work of setting were given.The changes of firmness and relaxation effort of cooled Turkey fillet at different storage terms were characterized.It was established, that organoleptically perceptible changes of structural-mechanical properties of Turkey fillet take place after 46 hours of storage. In first turn, relaxation is decelerated, the firmness limit is lowered that together with less firmness limit of fibers allows recommend it for formation of natural culinary goods of the given form, for example, rolls.The offered equipment and methodology of getting results of axial relaxation and penetration allows make conclusions about the essence of changes of rheological properties of Turkey fillet and also recommend the studied samples for one or another type of culinary processing

Socially responsible business formation in Ukraine

The paper reviews development process of social responsibility of business in Ukraine during transition of its economy to market. Today social responsibility of business is understood by national entrepreneurs as marketing or PR-technology, this way it is limited to social events. In this interpretation the concept can not support stable development both at micro- and macro level and provide competitive edge for enterprises in the longer term. The author suggests possible scenarios for developing of social responsibility of business in the crisis.Social responsibility, business, formation, negative factors, trends, crisis., Labor and Human Capital, Public Economics, Ðœ14, Ð13,

Particle production at energies available at the CERN Large Hadron Collider within evolutionary model

The particle yields and particle number ratios in Pb+Pb collisions at the LHC energy $\sqrt{s_{NN}}=2.76$ TeV are described within the integrated hydrokinetic model (iHKM) at the two different equations of state (EoS) for the quark-gluon matter and the two corresponding hadronization temperatures, $T=165$ MeV and $T=156$ MeV. The role of particle interactions at the final afterburner stage of the collision in the particle production is investigated by means of comparison of the results of full iHKM simulations with those where the annihilation and other inelastic processes (except for resonance decays) are switched off after hadronization/particlization, similarly as in the thermal models. An analysis supports the picture of continuous chemical freeze-out in the sense that the corrections to the sudden chemical freeze-out results, which arise because of the inelastic reactions at the subsequent evolution times, are noticeable and improve the description of particle and number ratios. An important observation is that although the particle number ratios with switched-off inelastic reactions are quite different at different particlization temperatures which are adopted for different equations of state to reproduce experimental data, the complete iHKM calculations bring very close results in both cases.Comment: 12 pages, 4 figure

Cross-over between diffusion-limited and reaction-limited regimes in the coagulation-diffusion process

The change from the diffusion-limited to the reaction-limited cooperative behaviour in reaction-diffusion systems is analysed by comparing the universal long-time behaviour of the coagulation-diffusion process on a chain and on the Bethe lattice. On a chain, this model is exactly solvable through the empty-interval method. This method can be extended to the Bethe lattice, in the ben-Avraham-Glasser approximation. On the Bethe lattice, the analysis of the Laplace-transformed time-dependent particle-density is analogous to the study of the stationary state, if a stochastic reset to a configuration of uncorrelated particles is added. In this stationary state logarithmic corrections to scaling are found, as expected for systems at the upper critical dimension. Analogous results hold true for the time-integrated particle-density. The crossover scaling functions and the associated effective exponents between the chain and the Bethe lattice are derived.Comment: 21 pages, 5 figures; v3: Scaling arguments at beginning of Section 4 were correcte
