Method for regeneration of mesenchymal tissue from mesenchymal cells on a porous sheet composed of bioabsorbable polymer material. The device includes an adjustable bracket and a positioning unit adapted to position the cable management arm with respect to the adjustable bracket between a rack and a chassis. The monitoring of the animal’s reproductive cycle consists of daily measurements of admittance or small AC current generated by time-varying voltage of small amplitude and sufficiently high frequency. The user device is linked to a user.
