Abstract: FIELD: oil extractive industry. 
     SUBSTANCE: method includes feeding of water along pipeline through mouth locking armature to input of single pump, pumping of water into force well along tubing pipes by said single pump while providing for necessary pressure, and extraction of oil through product wells. Firstly, extraction is performed with pumping of working agent in cyclical mode from pump station until finding sectors with low bed pressures. At deposit portion with lowered bed pressure a single pump is placed on day surface on mouth of force well. Effectiveness of single pump is selected to be enough for providing for maximum well acceleration. Working agent is pumped by said pump in individual mode through force well until restoring bed pressure and increasing debits in all surrounding product wells. Product wells are stopped in turns starting from first reacted to last reacted on operation of said pump.

Abstract: FIELD: medicine. 
     SUBSTANCE: method involves removing full-layer segment of lower eyelid and suturing skin with along defect wound boundary from lateral and medial side. The sutured defect edges are taken on holders. Horizontal flaps are cut along defect edge from conjunctiva. The flaps correspond to defect in size. Upper boundary of each flap passes along conjunctiva and tarsus boundary, the lower one is 1 mm far from eyeball. Each flap is sutured. Each flap is stretched by pulling all flaps towards each other using the holders, establishing in this way flap mobility degree. Primary defect suturing being found impossible, additional undercutting of horizontal flaps is carried out on each side. Conjunctiva is sutured and the defect is covered next to it with skin flaps according to local conditions. The method is applied when defect is localized in the lower eyelid region taking 1/4 to 1/3 of eyelid area. 
     EFFECT: accelerated treatment course; reduced risk of injuries and lower eyelid ectropion complications.

Abstract: FIELD: medical engineering. 
     SUBSTANCE: method involves manufacturing lens from material capable of photopolymerization, forming one or several lenses with required focal distance by introducing required quantity of the lens material in liquid state into cylindrical holder which material possesses required wetting angle for given liquid. The holder is placed on centrifuge and rotated together with the lens material to achieve uniformity under preset rotation frequency condition. Then, when rotating, the lens material is transformed into solid state due to light source radiation flow being applied. Rotation is stopped and lens is assembled in the holder. Oligomer composition, capable of frontal free radical photopolymerization with monomer corresponding to it, and reaction photoinitiator, is taken as the lens material. Working temperature is to be not less than on 30-40°C higher than polymer glass-transition temperature during polymerization. The lens material transformation into solid state by applying rotation is carried out by means of frontal photopolymerization method with polymerization front moving along the lens axis from below upwards or along the lens radius. 
     EFFECT: enhanced effectiveness in producing x-ray lenses having paraboloid-of-revolution refraction structure and having aperture increased to several millimeters without microroughnesses available on the surface.
