    We present chemical abundances in the photosphere of δ\delta Scuti -- the prototype of the class of pulsating variables -- determined from the analysis of a spectrum obtained at Terskol observatory 2 meter telescope with resolution R=52,000R=52,000, signal to noise ratio 250. VLT and IUE spectra were used also . Abundance pattern of \dsct consists of 49 chemical elements. The abundances of Be, P, Ge, Nb, Mo, Ru, Er, Tb, Dy, Tm, Yb, Lu, Hf, Ta, Os, Pt, Th were not investigated previously. The lines of third spectra of Pr and Nd also are investigated for the first time. The abundances of heavy elements show the overabundances with respect to the Sun up to 1 dex. The abundance pattern of \dsct is similar to that of Am-Fm stars.Comment: 8 pages, 2 figures, subm. to Proc. of IAU Symp. 22

    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
