Abstract: The invention relates to a method for maintaining equipment likely to go through at least a degraded state before failing, this equipment being provided with a data sensor, linked to a recorder, which is in turn associated with a processing unit, which comprises the following steps of: detection of states of the equipment from the recorded data, and by means of a hidden Markov model, determination of an optimal maintenance date as a function of a state of the equipment, of a predetermined aggregate usage time of the equipment, by using an optimal stop on PDMP, which comprises: a substep of calculation of a quantization grid made up of cells with, for each cell, the transition date, the state of the equipment on that transition date, the time spent in the preceding state, the probability of being in said state on said date, a substep of calculation of a discretized grid of remaining usage time for each cell of the quantization grid, a substep of calculation of the maintenance date starting from a state of the

Abstract: The present invention thus concerns a method for treating and/or preventing rickets, osteoporosis, osteomalacia, psoriasis, autoimmune diseases such as multiple sclerosis or type I diabetes, hyperparathyroidism, benign prostate hyperplasia, any type of cancer or any vitamin D relevant disease comprising administering inecalcitol at doses comprised between 1 mg/day and 100 mg/day to a human patient in need thereof.

Abstract: A method and assembly adapted to extract petroleum from a bore hole or well and particularly using steam to release the petroleum from the surrounding underground. These method and assembly include the release of steam at the bottom of a tube section and extraction of petroleum above the steam outlet to provide simple and efficient assembly and method, which allow for simultaneous feeding of steam and pumping out of petroleum. The assembly includes coaxial tube sections wherein steam pipes are placed in the annular space between the tube sections to outwardly feed steam at the bottom of the latter while defining a central passage for pumping the petroleum therefrom.
