HYDRAULIC DEVICES FOR HYDROSYSTEM TAILRACE PROTECTION
DescriptionBased on the Karman vortex theory, the calculated dependences for velocity induced by profile action in the flow, lifting force and drag force, acting on the profile, are determined. Calculations, performed in MathCAD, allowed, for the given up-stream velocity, to calculate height of mid-section of the bed-formation profile, width of the profile along the chord, span of the profile, angle of attack, velocity of the induced flow. For the calculated profile parameters, the velocity circulation value, drag force and lifting force are determined. As the bed-formation profiles, it is recommended to use flat plates, frame constructions with transverse ribs in the form of arch, fish-like symmetric or slightly curved profiles. Ways of the profile installation in the flow, depending on the angle of attack, are evaluated: three versions - for symmetric profiles, and six versions - for asymmetric profiles. Diagram of the device for the hydrosystem tailrace protection against erosion is developed on the basis of submerged NACA 0302 profile or profile of Zhukovsky, made of flexible materials, including profiles, system of supporting and regulating ropes, and shore or bottom supports. This design is mobile, intended for the periodic regulation of sediment yield

Description
The researches have been conducted for the optimization of culture medium for unique genotipes of Populus tremula L. in vitro. It was found that for induction of proliferation of the arms of Populus tremula in vitro one should use MS culture medium with 0,1 ml / l IBA and 0,1 or 0,5 ml / l BAP. For stimulation of rhizogenesis MS culture medium with 0,3 ml / l IBA should be used
