    We study the sensitivity of a 500 GeV e+ee^+e^- Linear Collider to CPCP violating anomalous couplings. We find that with 50~fb1^{-1}, and taking only one non-zero coupling at a time, the process e+eW+We^+e^-\to W^+ W^- can be used to place the 95% confidence level bounds κ~γ0.1|\tilde\kappa_\gamma|\leq0.1, κ~Z0.1|\tilde\kappa_Z|\leq 0.1 and g4Z0.1|g_4^Z|\leq 0.1 from CP even observables. By studying certain distributions in the process e+eμ+μννˉe^+e^-\to \mu^+\mu^-\nu\bar{\nu} one of the bounds can be improved to g4Z0.06|g_4^Z| \leq 0.06. This process also allows the construction of a CP odd observable which can be used to place bounds on CP violating new physics. At the 95% confidence level we find κ~γ0.3|\tilde\kappa_\gamma|\leq 0.3, κ~Z0.2|\tilde\kappa_Z|\leq 0.2 and a much weaker bound for g4Z|g_4^Z|.Comment: 18 pages LaTeX, 11 figures using eps

    There was offered and grounded the use of functional technological properties of the soya protein isolate in the technology of oil pasts. It will allows to increase the balance of the oil past composition additionally and will favor the decrease of extracting moisture during the storage term.There was studied the dynamics of a gradient of the limit stress of soya protein: hydrated soya protein, hydrated soya protein with the temperature processing, hydrated soya protein with the preliminary keeping during 24 h, hydrated soya protein with the preliminary keeping during 24 h and temperature processing during 5 min, hydrated soya protein with the preliminary keeping during 24 h and temperature processing during 10 min; hydrated soya protein with the preliminary keeping during 24 h and temperature processing during 15 min.It was established, that the hydrated isolate of soya protein is a plastic system, has enough strength.The limit stress parameter at the variable velocity of deformation of model samples determines optimal technological parameters of preparing the soya isolate: hydromodule – 1: 8, temperature processing – (82±2) °С, process duration 10 min with preliminary keeping during 24 hours.As a result of the studies, there were demonstrated technological parameters of preparing the soya protein isolate for obtaining the oil past by the direct mixing with the oil base

    For forming structural-mechanical properties of sour milk pastes and guaranteeing their stability at storage, it is promising to use non-fried buckwheat in their recipes that allows to raise the food value of products additionally. The aim of the researches was the study of features of the condition of moisture of sour milk pastes, based on sour cream with introducing non-fried buckwheat in the amount 5,0 % of the mixture mass. A sample with modified starch Е 1410 was taken as a control in the amount 1,3 %.The study of the moisture condition was realized by the thermogravimetric method using a derivatograph Q-1500D (Paulik-Erdey) (Hungry). It was established, that the content of adsorptive moisture of the sour milk paste was 34,0 %, whereas in the control – 34,5 %, that confirm the effectiveness of using non-fried buckwheat as a moisture-binding component. Such properties of non-fried buckwheat may be explained by the presence of starch compounds and easily accessible protein in its composition, able to hydration in the process of preparation of a component and to keeping moisture at further storage of a product

    An evaluation of |Vus| and precise tests of the Standard Model from world data on leptonic and semileptonic kaon decays

    Full text link
    We present a global analysis of leptonic and semileptonic kaon decay data, including all recent results published by the BNL-E865, KLOE, KTeV, ISTRA+ and NA48 experiments. This analysis, in conjunction with precise lattice calculations of the hadronic matrix elements now available, leads to a very precise determination of |Vus| and allows us to perform several stringent tests of the Standard Model.Comment: LaTeX, 25 pages, 12 figures, 16 tables.
