Abstract: The invention relates to radiographic equipment comprising a height-adjustable board, a C-shaped arch, disposed transversally to the greater dimension of the board, said board being housed within the internal space defined between the two free extremities of the arch. The arch is slidingly mounted on a column by means of a connecting element in such a way that as the arch rotates around an imaginary rotational axis it causes the connecting element to slide or roll throughout the extension of the arch. It further comprises a rail extending parallel to the greater dimension of the board, on which the column rests. The arch features at its lower extremity an x-ray receiver and at its upper extremity an x-ray emission assembly.

Abstract: Embodiments include a x-ray imaging system, apparatus, and method for use thereof. The apparatus comprises a first vertical column attached to a floor surface and configured to support an x-ray source; a second vertical column attached to the floor surface at a first distance opposite the first column and configured to support an x-ray imaging detector; and a positioning system configured to control vertical and angular movement of the x-ray source relative to the first column, wherein prior to image acquisition, the positioning system is configured to move the x-ray source to an initial height determined based on the detector height, and during image acquisition, the positioning system is configured to move the x-ray source to a plurality of positions along a trajectory defined by an upper angular position, a home position, and a lower angular position.

Abstract: The invention relates to radiographic equipment comprising a height-adjustable board (1), a C-shaped arch (3), disposed transversally to the greater dimension (D) of the board (1), said board being housed within the internal space defined between the two free extremities (3?, 3?) of the arch (3). The arch (3) is slidingly mounted on a column (4) by means of a connecting element (5) in such a way that as the arch (3) rotates around an imaginary rotational axis (13) it causes the connecting element (5) to slide or roll throughout the extension of the arch (3). It further comprises a rail (12) extending parallel to the greater dimension of the board (1), on which the column (4) rests. The arch (3) features at its lower extremity (3?) an x-ray receiver (6) and at its upper extremity (3?) an x-ray emission assembly (7).

Abstract: An x-ray imaging system is provided, the system comprising an x-ray source configured to emit an x-ray beam towards an x-ray imaging detector. The x-ray imaging detector is configured to obtain an x-ray image of an object placed adjacent to the x-ray imaging detector and at least partially within a path of the x-ray beam. The system further includes a pre-exposure device positioned between said object and the x-ray source. The pre-exposure device comprises a blocking component having an arrangement of openings across an extent of the component. The pre-exposure device has an active state wherein said blocking component is configured to reside within the path of the x-ray beam, and an inactive state wherein said blocking component is configured to not reside in the path of the x-ray beam.

Abstract: Methods for modifying the wettability of sandstone. Compositions comprising sandstone having a modified wettability. Such wettability modifications may be useful, for instance, in improving the well-deliverability of an oil and/or gas well located in a sandstone formation.

Abstract: Includes at least one floating body (1), and is characterised in that includes a device (2) fitted inside said body (1) for transforming the movement of the floating body (1) into pneumatic or hydraulic energy and means for transmitting the energy to dry land or to a fixed structure. An energy-generation system is obtained thereby with a manufacturing time and cost lower than the systems currently known. Moreover, the fact that the transforming device (2) is fitted inside the floating body (1) means that it is protected against corrosion caused by the water, against sharp movements caused by marine currents and against other possible outside agents which might harm or damage any of the components which make up the device.
