Abstract: The invention relates to 2-octylcyclopropyl-1-carboxylic acid, in particular in the form of one of the isomers thereof in isolated form or in the form of a mixture of at least two of said isomers. The invention further relates to a method for synthesizing 2-octylcyclopropyl-1-carboxylic acid or at least one of the isomers thereof. Finally, the invention relates to the use of 2-octylcyclopropyl-1-carboxylic acid or of one of said isomers in isolated form or of one of the mixtures of at least two of the isomers thereof, as a perfuming agent. The invention further relates to the compositions including 2-octylcyclopropyl-1-carboxylic acid or one of said isomers in isolated form or one of the mixtures of at least two of the isomers thereof, as a perfuming agent.

Abstract: The invention is a method for exploitation of a sedimentary basin containing hydrocarbons, including optimized scaling of the geological model. Based on categorical property measurements, a first meshed representation of a formation is constructed reflecting the categorical property measurements. At least one second meshed representation having a lower resolution is constructed by assigning a categorical property value to each mesh of the second representation corresponding to a group of meshes of the first representation and storing parameters for changing from the second representation to the first representation with those change parameters enabling reconstitution of the first representation.

Abstract: A differential-logic logic circuit chained with another differential-logic circuit comprises a first logic cell composed of back-gate transistors, the first cell having a first input for receiving a first input signal and having an output for delivering a first output signal, and a second logic cell complementary to the first cell, composed of back-gate transistors, the second cell having as many inputs as the first cell, each input able to receive an input signal complementary to the respective input signal of the first cell, the second cell having an output for delivering a second output signal complementary to the first output signal of the first cell. The first output signal of the first cell is applied to the back gate of each transistor of the second cell, and the second output signal of the second cell is applied to the back gate of each transistor of the first cell.
