Abstract: FIELD: shipbuilding. SUBSTANCE: proposed propulsor has body secured in fairing for reciprocating motion of working member mounted on rod of drive. Drive is made in form of hydraulic cylinder and piston-blade is used as working member for performing motion in cylinder secured in propulsor body by means of struts at clearance between body and cylinder forming nozzle directed to side opposite to fairing, thus creating thrust for motion of water craft at forward stroke of piston-blade due to displacement of water from cylinder at simultaneous filling space between fairing and piston-blade through nozzle and clearance between cylinder and body with water due to hydrostatic pressure and pressure of piston-blade. At reverse stroke of piston-blade, water is displaced from cylinder between fairing and piston- blade through clearance and nozzle, thus also creating thrust for motion of water craft.

Abstract: FIELD: search for mineral wealth. SUBSTANCE: seismic vibrations excited by sources and received by detectors are summed up by common points of reception and excitation to obtain time seismic sections of profile in the form of collection of signals of summary routes. Mentioned sections are rectified by way of input of static corrections. Fixed groups ( bases ) are selected from detectors of seismic vibrations uniformly arranged along profile and summation of seismic vibrations received by detectors on corresponding adjacent bases is carried out per each source. Fixed bases of sources are also selected and summation of seismic vibrations excited by sources on corresponding fixed bases is also carried out per each detector. At least two routes belonging to two different fixed bases of summation spaced along profile are obtained per each detector and source in process of summation. Surface anomalies are isolated on time seismic sections by coincidence sign of time distortions of reflections on time seismic sections related to different bases of summation. Boundaries of anomalies and values of time shift of times of arrival of reflected waves within limits of anomaly relative to smoothed lines of time of arrival of reflected waves conducted by points outside of anomalous districts are established. These time shifts averaged by collection of obtained time seismic sections are entered as static corrections into obtained seismic data. EFFECT: raised authenticity of detection of surface anomalies of various extent thanks to surface-timed summation of data of seismic prospecting. 4 cl, 10 dwg

Moreover, marking of skin transplant should be performed in donor's area against the lower edge of orbital-palpebral area of the upper palpebral groove and above the same or paired eye. Area if skin transplant corresponds to that of palpebral defect area and its configuration, as well. After simultaneous transfer of skin transplant into palpebral defect area and its preliminary fixation by edges with directing sutures one should apply successive application of compression flat elastoelastic plates with openings of hexahedral, oval, round or elliptic shape along their whole surface. Then through the above-mentioned openings one should fix skin transplant along its whole area with interrupted suture to underlying and surrounding tissues in palpebral defect area by capturing the surrounding tissues. Antiseptic preparation should be applied onto plates' surface. Plates and sutures should be removed from the wound on the 3-8 th  d after operation, and blepharorrhaphic sutures - on the 10-12 th  d after operation. The method enables to obtain complete adaptation in all cases of color- and structure-homogeneous transplant without its necrosis and detachment, exclude postoperational complications, transplant's wrinkling and secondary deformation of postoperational area.
