  • Patent number: 11981860
    Abstract: The present invention describes a hydraulic cement composition, process and use thereof, wherein the composition comprises a hydraulic cement composition with increased resistance against carbon dioxide (CO2) for application in reservoirs such as oil and gas and carbon capture and storage (CCS) wells; with improved performance of cement paste formulations as a material for application in primary, secondary cementing, recovery and/or plugging operations, of reservoirs/wells that operate with high CO2 content; as a technological alternative to guarantee the integrity of wells in CO2-rich environments for long periods of time, without any additional intervention to the already current operational procedures for cementing wells, and with cost reduction in relation to class G cement (currently, the main raw material); and sufficient chemical resistance to carry out enhanced oil (EOR) and gas (EGR) recovery by injecting high levels of CO2, increasing reservoir pressure throughout the extraction period of hydrocarbo

  • Patent number: 11118789
    Abstract: A monitor for a natural gas-fired appliance is provided. The monitor comprises: a natural gas cycle-monitor interface configured to receive cycling signals from one or more of: the appliance; and a monitoring device located in the appliance and/or proximal to the appliance; a processor, in communication with the interface, configured to monitor cycles of the appliance based on the cycling signals; one or more indicators, in communication with the processor, configured to provide an alarm when the processor determines that the cycles of the appliance meets a threshold value; a first reset device configured to temporarily reset the one or more indicators to turn off the alarm when actuated, the one or more indicators again providing the alarm after a given time period following a temporary reset; and, a second reset device configured to reset monitoring of the cycles at the processor when actuated.

  • Patent number: 10730912
    Abstract: Template-fixed ?-hairpin peptidomimetics of the general formula wherein Z is a template-fixed chain of 12 ?-amino acid residues which, depending on their positions in the chain (counted starting from the N-terminal amino acid) are Gly, or Pro, or of certain types which, as the remaining symbols in the above formula, are defined in the description and the claims, and salts thereof, have the property to selectively inhibit the growth of or to kill microorganisms such as Pseudomonas aeruginosa. They can be used as disinfectants for foodstuffs, cosmetics, medicaments or other nutrient-containing materials, or as medicaments to treat or prevent infections. These ?-hairpin peptidomimetics can be manufactured by processes which are based on a mixed solid- and solution phase synthetic strategy.

  • Patent number: 8850463
    Abstract: A system and method for capturing and recording parameters of events on portable devices with a digital television receiver, a method for remote configuration of service parameters for capturing and recording events on portable devices, as well as a portable device and server. More specifically, a system and method for capturing audience data, the method for remote configuration of audience data capture service, especially adapted for digital TV services on portable devices such as mobile phones, smartphones, and personal digital assistants, among others, that helps in remotely setting up the service. Another aspect of the present architecture is the fact that it is completely based on software, using only resources that are already present in portable devices with an embedded service.

  • Publication number: 20050281836
    Abstract: This invention is related to the field of immunology of protein biotechnology and particularly to the construction of synthetic immunogens which result, where inoculated, in the production by cattle of an immune response capable of lesion to the ticks feeding on the inoculated bovines, reducing their number, their weight and their reproductive capacity to such an extent that the constructed immunogen can be used as an effective vaccine for tick control on bovines. The technical object of the invention consists of the design and construction of two synthetic immunogens constituted of a continuous and defined sequence with forty-three (43) amino acids, found in different positions in the sequence of protein Bm86, their polymerization with cysteine in the N-terminal and in the C-terminal, the medicamentous composition based on said peptide(s) and the synthetic vaccine obtained thereby.
