Abstract: Solar/Rankine steam cycle hybrid concentrating solar power (CSP) systems and methods for designing or retrofitting existent natural circulation boilers using saturated or superheated steam produced by direct steam generation (DSG) or Heat Transfer Fluid (HTF) steam generators and CSP solar field technology systems are described. Additionally, methods and processes of retrofitting the existent Heat Recovery Steam Generators (HRSG) or biomass, gas, oil or coal fired boilers to operate integrated to a molten salt/water-steam heat exchangers are disclosed. The hybrid CSP systems are highly efficient due to the increase of steam generated by a heating section comprising either the DSG receiver or the molten salt-water-steam sequential heat exchangers, heaters, boiler/saturated steam generators, super-heaters and re-heaters.

Abstract: A polypeptide sperm bio-stabiliser FB-sp having the following sequence of amino acids: RPGLPVFSPL is provided; the use of the polypeptide bio-stabiliser for preserving the gametes of animals; a composition having the polypeptide bio-stabiliser; a conventional or alternative method for artificial insemination involving the use of the composition in conjunction with extender means to be injected into the females of animal species for commercial use.

Abstract: The present invention is directed to an active agent with contraceptive properties which corresponds to a peptide fragment of the Latrodectus mirabilisi's venom. The peptide generally includes the amino acid sequence of SEQ ID NO 2 or sequences that are at least 85% similar, obtained by chemical synthesis or through recombinant DNA technologies. Furthermore, a pharmaceutical contraceptive composition comprising the peptide fragment and one or more pharmaceutically acceptable vehicles is also described. The peptide fragment and pharmaceutical compositions are useful as a contraceptive and spermicide agent.

Abstract: The present invention is directed to an active agent with contraceptive properties. Said active agent corresponds to a molecular fraction of the venom from the spider Latrodectus mirabilis. The active agent is a peptide with a sequence according to SEQ ID NO 1 or sequences that are at least 85% similar, obtained by chemical synthesis or through recombinant DNA technologies. In a preferred embodiment, the active agent with contraceptive properties is a peptide with 10 to 30 amino acids, preferably 20 amino acids. Said embodiment is exemplified by the sequence identified as SEQ ID NO 2 or sequences that are at least 85% similar, obtained by chemical synthesis or through recombinant DNA technologies. Furthermore, a method to obtain the contraceptive peptide is disclosed, said method comprising cloning the nucleotide sequence in a microorganism.

Abstract: The present invention relates to a kitchen-range (1) and/or an oven (100) with a self-cleaning system, having a cleaning-element spraying assembly (6, 7, 106, 107), preferably water with detergent, arranged at the cooking top (13) and/or cooking chamber (113) for spraying it in a pressurized way and removing the existing dirt. A circuit is coupled to the cooking top (13) and/or cooking chamber (113), formed by conduits (5, 105, 4, 104) and a pump (19), so that the sprayed cleaning-elements can circulate and remove dirt from the surfaces to be cleaned.
