The search for high-efficiency luminescent compounds (phosphors) which are made from abun- dant elements with less impact on the environment is a research area of increasing importance. In this context, various strategies have been implemented to identify host compounds that can lead to optically active species incorporation, and anticipating good...
La formación de estrellas binarias y múltiples son un resultado frecuente del proceso de formación estelar, el cual tiene origen en el seno de condensaciones (o núcleos) pre-estelares que conforman la estructura de las nubes de gas interestelar. Observaciones de la población estelar muestran que casi la mitad de las...
Los sistemas actuales cada vez se vuelven más difíciles de integrar, instalar, configurar y mantener, además del gran costo que esto conlleva. La computación autonómica busca solucionar estos problemas mediante el desarrollo de sistemas que permita la auto-gestión de ellos mismos. Los sistemas de información para el cuidado de la...
The edible films can extend life and improve food quality by acting as a mechanical protection and a selective barrier to the transmission of gases, fumes, smells, tastes and solutes. Act as a support for carrying active substances such as antibiotics, probiotics, antioxidants, and others. It has been suggested the...
Un reactor nitrificante en continuo en estado estacionario sirvió como fuente de inóculo para realizar cultivos nitrificantes en lote y operar dos reactores de lotes secuenciados (SBR) nitrificantes. En ambos sistemas de estudio, se evaluó el efecto del p-cresol sobre el metabolismo de un consorcio nitrificante, así como la capacidad...
Ionic liquids biocompatibility on the strain Escherichia coli TOP10 pQR239, which expresses the recombinant enzyme cyclohexanone monooxygenase, was studied. Two ionic liquids (Trioctilmetilamonium bis [(trifluoromethyl) sulfonyl] imide, [OMA] [BTA] and Butilmetilpirrolidinium bis [(trifluoromethyl) sulfonyl] imide), [MeBuPyrr] [BTA], were used. [OMA] [BTA] was found to be significantly more biocompatible than [MeBuPyrr]...
In previous work on the production of lovastatin by Aspergillus terreus, we found that the concentration of reactive oxygen species (ROS) increased to high levels precisely at the beginning of the production phase (idiophase) and that these levels were maintained throughout the idiophase. Furthermore, ROS were shown to regulate lovastatin...
The subject of this thesis is oriented to the development of novel beers made 100% with varieties of pigmented corn. The study approaches from two perspectives: the chemical and the sensory approach. From the sensory point of view, this thesis addresses the conceptualization of a ‘corn beer’, the sensory profiling...
