The invention concerns an enhanced oil recovery process improving the gas sweeping of an oil formation reservoir comprising at least one injection, through at least one injection well, either simultaneously or separately, of a plug of solution, preferably aqueous, of at least one surfactant and of a gas and/or steam plug (or "slug"), so as to form a foam. At least a portion of said reservoir is swept by said foam and the hydrocarbons are recovered through at least one producing well. The surfact...

For the thermal conversion of hydrogen sulfide contained in a gaseous stream, the gaseous stream is introduced into a non-catalytic reactor together with sulfur dioxide obtained from a waste gas purification facility arranged downstream of the reactor. If necessary, the sulfur yield can be regulated by feeding additional fuel gas and/or reducing gas and/or process air into the reactor. The thus-produced vapor-phase sulfur is condensed out by cooling and is obtained as a product; the resultant ga...

Process for the treatment of a hydrocarbon mixture that comprises hydrogen, in which the mixture is separated at pressure P1 into a liquid L1 and a gas G1 that is compressed under a pressure P2>2.times.P1; compressed gas G1** is then brought into contact with at least a portion of L1 so as to recover a liquid L2 and a hydrogen-rich gas G2; at least one stabilized liquid and a light liquid stream LL comprising primarily LPG, of which at least a portion is reduced in pressure and mixed with gas...

The invention relates to a method for determining the concentration of thrombin inhibitors in a non-turbid body liquid or a non-turbid extract from a body liquid. It comprises the following steps. The body liquid is taken from a living body, and the body liquid is subjected to a separation from the turbid matter, if necessary. To the non-turbid body liquid thus obtained are added a coagulation-inhibiting substance not interfering in the transformation prothrombin/active meizothrombin or Mtdesfgl...

Two human MATER proteins as well as their use for fertility disorders, therapy and diagnosis are described.

The invention relates to a polyamide-based thermoplastic composition comprising, by weight: 50 to 98 parts of a polyamide (A1) nondiamine; 0.2 to 40 parts, preferably 0.2 to 9 parts, of a polyamide (A2) diamine, said polyamide (A2) being different from the polyamide (A1) and the ratio by mass (A2)/(A1) being less than 1; 1 to 60 parts, preferably 1 to 30 parts, of a reactive impact modifier (B) or of a blend of modifiers comprising at least one reactive impact modifier (B) or of a blend (B') com...

The invention concerns low-molecular platinum complexes containing cyclobutane-1,1-dicarboxylate ligands that contain a protein-binding group.

Novel compounds of the formula I ##STR00001## in which R, X, n and m are as defined herein are inhibitors of tyrosine kinase and can be employed for the treatment of tumours, for neuroprotection and for protection of the stress proteins of the skin.

This invention relates to pyrimidine derivatives of general formula I ##STR00001## in which R.sup.1, R.sup.2, X, A and B have the meanings that are contained in the description, as inhibitors of the cyclin-dependent kinases, their production as well as their use as medications for treating various diseases.

A process is described for synthesising hydrocarbons from a mixture comprising carbon monoxide and hydrogen and possibly carbon dioxide CO.sub.2, in the presence of a supported catalyst comprising at least one group VIII metal. The support comprises zirconia or a mixed zirconia-alumina oxide and the zirconia is present in the quadratic and/or amorphous form. Said catalyst is used in a liquid phase in a three-phase reactor.
