Abstract: The invention relates to a THC-free cannabinoid concentrate, method of obtaining the same and use thereof. The method of obtaining comprises an alkaline wash to purify lipid extracts.

Abstract: The present invention relates to a method and a control unit for avoiding condensation of humidity in an intake system of an internal combustion engine after engine switch off. Condensed liquid in the intake system of the stopped engine can lead to icing, corrosion and a hydrostatic lock at the next engine start. To prevent such an engine damage, it is necessary to determine if and in which amount condensed liquid occurs in the cooled intake system and to initiate appropriate actions to eliminate the liquid therefrom. The present invention predicts the occurrence of condensation in the intake system of the cooled engine and initiates corrective measures at engine switch off and during the cooling down period.

Abstract: A method for extracting a subset of data from an ordered set of bi-dimensional matrices (data arrays) such as a sequence of pictures or a multi-dimensional matrix, for instance, is implemented by dedicated hardware that may be used each time it is necessary to extract a subset of data from a data array. For each matrix of data, the method calculates very quickly row and column indices of border data of the portion to be extracted, which are obtained by arithmetical operations among row and column indices of vertices of a closed area of interest. The method is implemented in a device for selectively transferring a data stream sampled at a certain bit-rate to a microprocessor unit or to a memory receiving the data stream at a different rate.

Abstract: The invention relates to the preparation of complexes of 99m-technetium, 186-rhenium or 188-rhenium usable as radiopharmaceutical products.For this preparation, an oxidized compound of .sup.99m Tc, .sup.186 Re or .sup.188 Re, e.g. an alkali metal or ammonium perrhenate or pertechnetate, is reacted with a first ligand chosen from the group of substituted or unsubstituted, aliphatic and aromatic phosphenes and polyphosphenes and a second nitrogenous ligand constituted by an ammonium nitride or a pharmaceutically acceptable metal or by a nitrogenous compound having a >N--N< unit, such as hydrazine, a hydrazine derivative, dithiocarbazic acid and dithiocarbazic acid derivatives.The product obtained can be used as it is as a radiopharmaceutical product or can serve as an intermediate for the preparation of other radiopharmaceutical products by exchange reaction with a third ligand, a monoclonal antibody or an antibody fragment.

Abstract: The invention relates to a radiopharmaceutical product more particularly having a cardiac tropism, incorporating a nitride complex of a transition metal and the process for the preparation thereof.This complex complies with the formula:(M.ident.N)L.sup.1 L.sup.2 (I)in which M is a transition metal, e.g. Tc99m, Re 186 or Re 188 and L1 and L2, which can be the same or different, comply with the formula: ##STR1## in which R.sup.1 and R.sup.2 can be alkyl radicals, V and W can be O, S or Se, n=0 or 1, m=0 or 1, and Y represents N, P or As.
