    The work studies the rational concentration of meals of soya, sunflower and milk thistle in a sandy dough semi-product for improving healthy properties of ready products (biological value, stomach peristalsis, metabolism, saturation with vitamins and mineral substances). Analytic studies were conducted and advantages of using meals in dough products were determined. The chemical composition of meals was determined, and the optimal composition for satisfying the human need that is in ratio 3:4:3 was calculated. The quality of meals was estimated, and their organoleptic parameters were analyzed. The sensor analysis of sandy semi-products of oilseed crops meals was realized. It was established, that adding of the meal composition instead of flour in amount 20 % is an optimal solution for using in a sandy dough semi-product.There was established the influence of meals of oilseed crops on organoleptic parameters of developed sandy semi-products. Advantages and defects of using the aforesaid meals were established. Ways of improving the outlook and consistence of shortcakes were offered. Ways of further studies were established

    Electron-phonon interaction and spectral weight transfer in Fe1x_{1-x}Cox_{x}Si

    A comprehensive ellipsometric study was performed on Fe1x_{1-x}Cox_{x}Si single crystals in the spectral range from 0.01 eV to 6.2 eV. Direct and indirect band gaps of 73 meV and 10 meV, respectively, were observed in FeSi at 7 K. One of four infrared-active phonons that is energetically close to the direct absorption edge is coupled both to the electrons and to the low-energy phonon. This is evident from asymmetry in the phonon line shape and a reduction of its frequency when the absorption edge shifts across the phonon energy due to the temperature dependence of the direct band gap. As the temperature increases, the indirect gap changes sign, which manifests as a transition from a semiconductor to a semimetal. The corresponding gain of the spectral weight at low energies was recovered within an energy range of several eV. The present findings strongly support the model indicating that Fe1x_{1-x}Cox_{x}Si can be well described in an itinerant picture, taking into account self-energy corrections.Comment: 12 pages, 12 figure

    Range of the t--J model parameters for CuO2_{2} plane: experimental data constraints

    Full text link
    The t-J model effective hopping integral is determined from the three-band Hubbard model for the charge carriers in CuO2_{2} plane. For this purpose the values of the superexchange constant JJ and the charge-transfer gap EgapE_{gap} are calculated in the framework of the three-band model. Fitting values of JJ and EgapE_{gap} to the experimental data allows to narrow the uncertainty region of the three-band model parameters. As a result, the t/Jt/J ratio of the t-J model is fixed in the range 2.4÷2.72.4 \div 2.7 for holes and 2.5÷3.02.5 \div 3.0 for electrons. Formation of the Frenkel exciton is justified and the main features of the charge-transfer spectrum are correctly described in the framework of this approach.Comment: 20pp., REVTEX 3.0, (11 figures), report 66

    Characteristics of insulin therapy of diabetes mellitus type 1 in children and adolescents receiving glucocorticoids

    BACKGROUND: In coexistence of diabetes mellitus type 1 (DM1) with severe autoimmune and inflammatory diseases some patients need simultaneous administration of insulin and glucocorticoids (GC). GC therapy in patients with DM1 can worsen glycemic control. AIM: To determine characteristics of insulin therapy of DM1 in children and adolescents receiving GC. DESCRIPTION OF CLINICAL CASES: We observed 5 patients with DM1 receiving GC for juvenile idiopathic arthritis (JIA), juvenile systemic sclerosis (JSS), juvenile dermatomyositis (JDM), ulcerative colitis (UC), and reactive arthritis (RA). Intra-articular administration of GC did not significantly influence glycemic control. In case of GC pulse therapy hyperglycemia and increased insulin requirements were recognized in 3–6 hours after GC receipt, persisted from few hours up to 3 days after each administration. While therapy with oral GC in high doses the worst glycemic control was registered in daylight hours. To overcome insulin resistance change of time of injection and 10%-increase of long-acting insulin analogue, additional injections of ultrashort-acting insulin analogues, temporal prescription of short-acting human insulin were used. While GC therapy insulin daily dose was individual and could reach 2.0 U/kg. After transition to maintaining doses of GC or discontinuation of GC therapy patients returned to standard or relatively low insulin requirements. Levels of glycosylated hemoglobin differed significantly among patients at different stages of treatment, were maximal while long-term therapy with high doses of oral GC, but mostly depended on patient’s compliance. CONCLUSION: Bettering of glycemic control while receiving GC can be reached by timely dose correction of insulin therapy, selection of individual schemes, taking into account time of receipt and pharmacokinetic characteristics of GC. Adherence of the patient and his family to treatment of DM1 plays an important role in glycemic control

    Charge Transport in Manganites: Hopping Conduction, the Anomalous Hall Effect and Universal Scaling

    Full text link
    The low-temperature Hall resistivity \rho_{xy} of La_{2/3}A_{1/3}MnO_3 single crystals (where A stands for Ca, Pb and Ca, or Sr) can be separated into Ordinary and Anomalous contributions, giving rise to Ordinary and Anomalous Hall effects, respectively. However, no such decomposition is possible near the Curie temperature which, in these systems, is close to metal-to-insulator transition. Rather, for all of these compounds and to a good approximation, the \rho_{xy} data at various temperatures and magnetic fields collapse (up to an overall scale), on to a single function of the reduced magnetization m=M/M_{sat}, the extremum of this function lying at m~0.4. A new mechanism for the Anomalous Hall Effect in the inelastic hopping regime, which reproduces these scaling curves, is identified. This mechanism, which is an extension of Holstein's model for the Ordinary Hall effect in the hopping regime, arises from the combined effects of the double-exchange-induced quantal phase in triads of Mn ions and spin-orbit interactions. We identify processes that lead to the Anomalous Hall Effect for localized carriers and, along the way, analyze issues of quantum interference in the presence of phonon-assisted hopping. Our results suggest that, near the ferromagnet-to-paramagnet transition, it is appropriate to describe transport in manganites in terms of carrier hopping between states that are localized due to combined effect of magnetic and non-magnetic disorder. We attribute the qualitative variations in resistivity characteristics across manganite compounds to the differing strengths of their carrier self-trapping, and conclude that both disorder-induced localization and self-trapping effects are important for transport.Comment: 29 pages, 20 figure

    Objectives: immunohistochemical study of the expression of molecular and biological markers (p53, bcl-2 and ki-67) in esophageal tumors of various stages and grades, and evaluation of the markers in the disease prognosis. Material and methods: the study included 30 patients of a retrospective group with stage II-III squamous cell carcinoma of the esophagus. Immunohistochemical study of paraffi n sections was performed using primary mouse monoclonal antibodies against p53, bcl-2 and ki67, and Reveal Polyvalent HRP-DAB Detection System. Results: diff erences in the rates and expression of molecular and biological markers (p53, bcl-2 and ki-67), controlling apoptosis and proliferation, depended on the tumor stage and grade. Conclusions: fdvanced cancer of the esophagus demonstrated an increase in rates and expression of p53+ and ki-67, as well as in the proliferative activity of tumor cells. Bcl-2 expression was more frequent and intensive in stage II tumors, compared to stage III. Esophageal tumors of higher grades were characterized with higher rates and expression of p53 and ki-67, and conversely for the bcl-2 expression. Th e revealed diff erences can be used in the disease prognosis
