Patent number: 8916118Abstract: The invention relates to a CO2 y SO2 capture method comprising the following steps consisting in: a) introducing an aqueous stream of a hydroxide of an alkali or alkaline-earth metal and another gas stream of CO2 into a bubble column purifier/reactor, in order to form a carbonate of the alkali or alkaline-earth metal; b) introducing the carbonate of the alkali or alkaline-earth metal into a bubble column purifier/reactor, into which a stream of a gas mixture of CO2 and SO2 is introduced in order to form sulphite of an alkali or alkaline-earth metal and carbon dioxide; c) transforming the sulphite from step (b) into sulphate of said metal by means of oxidation with air; and d) re-circulating the unreacted CO2 produced during step (b) by reacting the slurry with the SO2, in the reactor from step (a).Type: GrantFiled: May 9, 2012Date of Patent: December 23, 2014Assignees: Consejo Superior De Investigaciones Cientificas, Universidad De Sevilla, Universidad De CadizInventors: Cristian Cardenas Escudero, Luis Maria Esquivias Fedriani, Victor Morales Florez, Alberto Santos Sanchez

Patent number: 8097307Abstract: The invention relates to a method of strengthening stone and other construction materials. The inventive method is performed on the monument, building or statue in question or on any other object that has undergone deterioration. It achieves the formation of a mesoporous molecular sieve with an ordered topology in the pores of the altered substrate. The invention is advantageous in that: by considerably increasing the radius of the pores of the gel in relation to that of commercial binders, capillary pressure is significantly reduced and, with it, the risk of fractures in the material; by obtaining a binder having a uniform pore radius, the risk of fracture is prevented since it impedes the occurrence of stresses caused by pores of different sizes; by obtaining a mesoporous material with a given pore volume, the pores of the altered substrate are prevented from being blocked and, consequently, the damp-proofing of the building is impeded.Type: GrantFiled: July 5, 2006Date of Patent: January 17, 2012Assignee: Universidad de CádizInventors: María Jesús Mosquera Díaz, Antonio Montes Herrera, Desiree De Los Santos Martínez

Publication number: 20110059850Abstract: The invention relates to phytotoxic halogenated derivatives of benzoxazinones. The aim of the invention relates to the production of novel phytosanitary products that are suitable for agricultural weed control, based on natural chemical substances. The invention comprises novel chemical compounds having high levels of phytotoxic activity and the preparation methods thereof. Said substances are derived from natural products with the 1,4-benzoxazin-3-one skeleton involved in different chemical defense interactions in plants. The inventive compounds have suitable phytotoxic activity levels for use in weed control and for use as stable models for the development of novel phytosanitary products based on the 1,4-benzoxazin-3-one skeleton.Type: ApplicationFiled: July 17, 2007Publication date: March 10, 2011Applicant: UNIVERSIDAD DE CÁDIZInventors: Francisco Antonio Macias Dominguez, Jose Maria Gonzalez Molinillo, Rosa Maria Varela Montolla, Nuria Chinchilla Salcedo, Joao Maximo De Siqueira, David Marin Mateos

Publication number: 20100256413Abstract: Method for the chemical synthesis of capsinoids, natural compounds with proven biological activity, from vanillin, comprising the protection of the alcohol group thereof, reduction of the aldehyde to alcohol, esterification of same and deprotection of the first protected alcohol group. In this way, the desired compounds are generated with high purity and said compounds can be easily separated with no mixing owing to the competitive esterification on the aromatic ring.Type: ApplicationFiled: April 11, 2008Publication date: October 7, 2010Applicant: UNIVERSIDAD DE CÁDIZInventors: José María González Molinillo, Francisco Antonio Macías Dominguez, Rosa María Varela Montoya, Miguel Palma Lovillo, Carmelo García Barroso, Gerardo Fernández Barbero

Publication number: 20100094108Abstract: Determining and monitoring desaturation indices and instantaneous respiratory rate, based on extracting components from the blood oxygen saturation (SpO2) signal captured by an oximeter, obtaining and processing the data in the frequency domain in order to detect respiratory events and determine values such as respiratory rate and deviations therefrom (tachypnea/bradypnea) and desaturation indices. Bioengineering applications in the field of medicine include monitoring and assisting with the diagnosis of respiratory disorders for its use in anesthesia, intensive care units and healthcare emergencies and assisting in the diagnosis of sleep apnea/hypopnea syndrome (SAHS).Type: ApplicationFiled: April 26, 2007Publication date: April 15, 2010Applicant: Universidad de CadizInventors: Juan Luis Rojas Ojeda, Antonio Leon Jimenez, Luis Felipe Crespo Foix, Nicole Gross, Daniel Sanchez Morillo

Publication number: 20100030085Abstract: Extraction of components of the a signal captured by an accelerometer, obtaining information about physiological data such as cardiac, respiratory and snoring activity. The extracted signal components are useful for the diagnosis of different types of abnormal respiratory phenomena during sleep (apneas, hypopneas and respiratory efforts associated to micro-arousals).Type: ApplicationFiled: April 26, 2007Publication date: February 4, 2010Applicant: Universidad de CadizInventors: Juan Luis Rojas Ojeda, Antonio Leon Jimenez, Luis Felipe Crespo Foix, Nicole Gross, Daniel Sanchez Morillo
