Cultivation of granular sludge with hypersaline oily wastewater
2015
The time required to stabilise mature aerobic granules is rather variable. In addition, cultivation time and the structural characteristics of granules seem to be related to the nature of wastewater influent. Granular sludge has been used for the treatment of several industrial wastewaters, but nothing has been reported about wastewater characterized by the simultaneous presence of hydrocarbons and high chloride concentration. In this work, the authors analysed the granulation process and performance as well as the physical characteristics of aerobic granules in two Granular Sequencing Batch Airlift Reactors (GSBARs), fed with acetate-based synthetic wastewater in reactor 1 (R1) and with a …
The genusThymus(Lamiaceae) in Sicily
2015
An update on the taxonomy and geographic distribution of the genus Thymus in Sicily is given. This study is based on literature, herbarium and field investigations. In total, five taxa belonging to Thymus sect. Serpyllum (Th. richardii subsp. nitidus, Th. longicaulis and Th. praecox subsp. parvulus) and Th. sect. Hyphodromi (Th. spinulosus and Th. paronychioides) occur in Sicily. For each one, information about taxonomy, habitat, phenology, chromosome number and distribution are provided. Furthermore, the name Thymus pedicillatus Lojac. is here typified. Finally, an analytical key for the identification of the studied taxa is proposed.
Two heterologously expressed Planobispora rosea proteins cooperatively induce Streptomyces lividans thiostrepton uptake and storage from the extracel…
2010
Abstract Background A bacterial artificial chromosomal library of Planobispora rosea, a genetically intractable actinomycete strain, was constructed using Escherichia coli-Streptomyces artificial chromosome (ESAC) and screened for the presence of genes known to be involved in the biosynthesis of antibiotics. Results One clone with a 40 kb insert showed antimicrobial activity against Gram positive bacteria. Insert sequence analysis and subcloning experiments revealed that the bioactivity was due to a 3.5 kb DNA fragment containing two open reading frames. These orfs encode two proteins with high similarity to a putative membrane protein of Streptomyces coelicolor and to the nogalamycin resis…
Generación de preguntas sobre información no textual : una validación empírica del modelo obstáculo-meta en la comprensión de dispositivos experiment…
2014
RESUMEN: Los mecanismos cognitivos de la generación de preguntas no son aún bien conocidos. Recientemente, se ha propuesto el modelo obstáculo-meta que asimila la comprensión a un proceso de resolución de un problema cognitivo, cuyos obstáculos hacia la meta pretendida dan lugar a las preguntas. Una predicción del modelo es la relación entre tipos de preguntas formuladas y tipos de representación mental que los sujetos manejan durante la comprensión de la información suministrada. Hasta ahora, esta predicción ha sido validada parcialmente y solo con información textual. En este trabajo se presenta un estudio empírico de validación más fiable de esta predicción, desarrollado en dos fases y q…
Measurement of the radiation energy in the radio signal of extensive air showers as a universal estimator of cosmic-ray energy
2016
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8±0.7(stat)±6.7(syst) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principles calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the d…
Performance of jet substructure techniques for large-$R$ jets in proton-proton collisions at $\sqrt{s}$ = 7 TeV using the ATLAS detector
2013
This paper presents the application of a variety of techniques to study jet substructure. The performance of various modified jet algorithms, or jet grooming techniques, for several jet types and event topologies is investigated for jets with transverse momentum larger than 300 GeV. Properties of jets subjected to the mass-drop filtering, trimming, and pruning algorithms are found to have a reduced sensitivity to multiple proton-proton interactions, are more stable at high luminosity and improve the physics potential of searches for heavy boosted objects. Studies of the expected discrimination power of jet mass and jet substructure observables in searches for new physics are also presented.…
Raons essencials i creença
2003
In this paper I defend that what I call modes of denotation are part of one¿s belief content, even if they are not part of the proposition expressed by the sentence one believes to be true. Two people, who believe of the same sentence (not ambiguous) that it is true can have different belief contents that they express by means of this same sentence.
El Concepto de transfinitud en García Bacca
2011
This paper presents the notion of transfinite developed by García Bacca in his «Infinito, transfinito, finito». This concept is a reaction to the Aristotelian concepts of «nature» and «finite», making man a historical being. García Bacca argues that man has lost his nature and his finitude through technology. So, strictly speaking, is not finite, nor infinite.
Corrección: una cuestión de estilo
2009
This paper is devoted to ask if Aesthetics today can be considered in the way of Baumgarten and Kant or it can be considered like a way to produce truth and truthfulness. Opposite to the ontological truth (aletheia) and the logic truth (homoisosis) the writer, from a point of view of Aesthetics, propose considering also truth like correctness, orthotés in classical Greek and rectitudo in Latin.
La filosofía y sus lógicas
2003
It is common use at the end of the century to make retrospectives in all domains: politics, sciences, military, arts... This has also been made in philosophy, and it tries to explain the world from fightings between one another, lists of great men names, the death of the field itself, rhapsodies of schools and philosophers, conceptual exhibitions of external problems (biographic, politic or colonial ones) and so on. In this paper, it is intended to give a criterium internal to the philosophy itself, in order to classify the philosophical thought all along the 20th century. This criterium has to be built as a philosophical idea in which are situated the methods, the ontologies and the ethics…
