The aim of the article is to study and to generalize technological properties of eggplant powder, produced by infrared drying at temperatures 50-60 ºС. The results of the conducted complex of studies reflect main technological and consumption properties of the received puree that plays an important role at creating new culinary products.So, for studying technological properties of food eggplant powder, there was considered the complex of base functional-technological properties of powder, produced by infrared drying.For finding optimal conditions of rehydration of eggplant powders, there was studied the influence of such technological factors as: swelling ability; liquid; powder ratio; influence of the solvent temperature on renovation; renovation duration; degree of comminution of powders.Main parameters that influence the renovation ability of dried eggplants are investigated and studied in the article. The results of the studies of technological properties of eggplant powders prove their high rehydration properties. It gives a possibility to use powders at producing different culinary products not only for enriching them with functional ingredients, but also for giving them new technological properties.Based on the obtained results, there was elaborated and presented the new technological scheme of using renewed powders in food compositions

On the Properties of Two Pulses Propagating Simultaneously in Different Dispersion Regimes in a Nonlinear Planar Waveguide

Properties of two pulses propagating simultaneously in different dispersion regimes, anomalous and normal, in a Kerr-type planar waveguide are studied in the framework of the nonlinear Schroedinger equation. Catastrophic self-focusing and spatio-temporal splitting of the pulses is investigated. For the limiting case when the dispersive term of the pulse propagating in the normal dispersion regime can be neglected an indication of a possibility of a stable self-trapped propagation of both pulses is obtained.Comment: 18 pages (including 15 eps figures

The surface core level shift for lithium at the surface of lithium borate

The shallow Li 1s core level exhibits a surface-to-bulk core level shift for the stoichiometric Li2B4O7(110) surface. Angle-resolved photoemission spectroscopy was used to indentify Li 1s bulk and surface core level components at binding energies -56.5 ± 0.4 and -53.7 ± 0.5 eV, respectively.We find photoemission evidence for surface states of Li2B4O7(110) that exist in the gap of the projected bulk density of states. The existence of surface states is consistent with the large surface-to-bulk core level shift for the Li 1s core

Дополнительное профессиональное образование как фактор развития человеческого капитала: вопросы теории

The paper considers classical models of human capital through the lens of further professional education. We specify the model of individual returns from investment in human capital (G. Becker), offer new tools to retain an employee after training for their subsequent use in a model of firm’s investments in human capital (G. Becker). We supplement M. Spence’s theory of educational signals with new educational stage and expand the scope of application of the model of human capital reproduction over the life cycle (J. Ben-Porat). These modifications allow us to confirm the expediency and profitability of investments of workers in further professional education.В статье рассмотрены классические модели человеческого капитала через призму дополнительного профессионального образования: уточнена модель индивидуальной отдачи от инвестиций в человеческий капитал Г. Беккера, предложены новые инструменты удержания работника после обучения для модели инвестиций фирмы в человеческий капитал Г. Беккера, дополнена новой образовательной ступенью теория образовательных сигналов М. Спенса и расширена область применения модели воспроизводства человеческого капитала в течение жизненного цикла Й. Бен-Пората. Модификации позволили подтвердить целесообразность и выгодность инвестиций работников в дополнительное профессиональное образование

Surface charging at the (1 0 0) surface of Cu doped and undoped Li2B4O7

Wehave compared the photovoltaic charging of the (100) surface termination for Cu doped and undoped Li2B4O7. While the surface charging at the (100) surface of Li2B4O7 is significantly greater than observed at (110) surface, the Cu doping plays a role in reducing the surface photovoltage effects. With Cu doping of Li2B4O7, the surface photovoltaic charging is much diminished at the (100) surface. The density of states observed with combined photoemission and inverse photoemission remains similar to that observed for the undoped material, except in the vicinity of the conduction band edge

The electronic structure of Li2B4O7(110) and Li2B4O7(100)

The band structure of Li2B4O7(100) and Li2B4O7(110) was experimentally determined using a combination of angle-resolved photoemission and angle-resolved inverse photoemission spectroscopies. The experimental band gap depends on crystallographic direction but exceeds 8.8 eV, while the bulk band gap is believed to be in the vicinity of 9.8 eV, in qualitative agreement with expectations. The occupied bulk band structure indicates relatively large values for the hole mass; with the hole mass as significantly larger than that of the electron mass derived from the unoccupied band structure. The Li2B4O7(110) surface is characterized by a very light mass image potential state and a surface state that falls within the band gap of the projected bulk band structure

Hydration interactions: aqueous solvent effects in electric double layers

A model for ionic solutions with an attractive short-range pair interaction between the ions is presented. The short-range interaction is accounted for by adding a quadratic non-local term to the Poisson-Boltzmann free energy. The model is used to study solvent effects in a planar electric double layer. The counter-ion density is found to increase near the charged surface, as compared with the Poisson-Boltzmann theory, and to decrease at larger distances. The ion density profile is studied analytically in the case where the ion distribution near the plate is dominated only by counter-ions. Further away from the plate the density distribution can be described using a Poisson-Boltzmann theory with an effective surface charge that is smaller than the actual one.Comment: 11 Figures in 13 files + LaTex file. 20 pages.
