Abstract: The invention teaches a method proposing two new indices for evaluating thermal evolution in oils from different basins and organofacies. The first index is based on the distribution ratio of high molecular weight sulfur compounds, belonging to the DBE 6 (benzothiophene) and DBE 9 (dibenzothiophene) series. The second index, called TEI, was created from the profile of aromatic hydrocarbons and molecules containing N, O and S. Both parameters were obtained from the direct characterization of the oils, by using the photoionization at atmospheric pressure (APPI) technique combined with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).

Abstract: A boom assembly for an agricultural applicator includes a frame supporting a boom arm pivotably coupled to the frame and rotatable about a first axis. A first actuation assembly is pivotably coupled to the frame and the boom arm at a first pivot point for rotation about a second axis on a first side of the first axis. A second actuation assembly is pivotably coupled to the frame and the boom arm at a second pivot point for rotation about a third axis on a second side of the first axis. A sensor is configured to detect data indicative of a relative position of the boom arm relative to the frame. A computing system is configured to activate at least one of the first actuation assembly or the second actuation assembly in response to determining that the boom arm has deviated from a predefined angular range.

Abstract: A weasand-ligating clip (10) made as a one-piece molding, the clip comprising two portions (11) hinged together at one end by a film hinge (13), and including a closure system (15, 16) at the other end, the portions (11) having teeth that clamp against the weasand when the clip is closed, the clip being characterized by the fact that a major longitudinal dimension (L) of the clip measured from the film hinge to the closure system is less than 45 mm, or indeed less than 42 mm, and better less than 40 mm.
