Abstract: FIELD: medicine, surgery. 
     SUBSTANCE: one should apply microsurgical anastomosis between a spermatic duct and epididymis in area of isolated loop of epididymal duct. Moreover, at first, one should form a posterior "lip" of anastomosis, then it is necessary to form a free loop of coiled epididymal duct of 2 cm length. One should invaginate a loop with a button-type probe into the lumen of spermatic duct in urethro-loop direction. Above the loop invaginated into the lumen of spermatic duct one should form anterior "lip" of anastomosis. The innovation enables to simplify the technique to form vasoepididymoanastomosis at treating male sterility.

Abstract: FIELD: mechanical engineering; air conditioning and ventilation. 
     SUBSTANCE: invention relates to heat exchange devices used in air conditioning and ventilating plants, namely, to methods of evaporating cooling to dew point and to plate devices for evaporative cooling.  According to invention, plates of plate device are made so that channels and perforation to pass from dry side to wet side can be at least partially wetted with evaporating liquid.  Chute is provided made in part of plates which temporarily holds evaporating liquid in contact with wick material on surface of wet side of plate.  Evaporating liquid flows along chute through perforation for liquid into following chute.  When chute of plate from wet side is from above, perforation for liquid is on side forming reservoir for wetting opposite wick materials.  When flow move along dry side, heat is conveyed to plate.  In proposed method several heat transfer plates are used.  Said plates have wet and dry sides and they form chutes.  Plates are wetted form wet sides with evaporating liquid and they pass separately two flows, namely, working and product ones through dry sides.  Flow of working gas passes along dry side and gets through perforation into channels on wet side which is cooled owing to evaporation, thermal conductivity of plate and its heat radiation. 
     EFFECT: provision of more effective air flow and heat transfer owing to evaporative cooling with intermediate coolant.
