Isolation of Gram-positive n-alkane degraders from a hydrocarbon-contaminated Mediterranean shoreline.
2007
Aims: To investigate the petroleum hydrocarbon (HC)-degrading potential of indigenous micro-organisms in a sandy Mediterranean coast, accidentally contaminated with petroleum-derived HCs. Methods and Results: Using culturable methods, a population of Gram-positive n-alkane degraders was detected in the contaminated soil. Five isolates, identified as one Nocardia, two Rhodococcus and two Gordonia strains, were able to degrade medium- and long-chain n-alkanes up to C36 as assessed by growth assays and gas chromatography-mass spectrometry analysis. Diverging alkane hydroxylase-encoding genes (alkB) were detected by PCR, using degenerated primers, in all the strains; multiple sequences were obt…
Effect of cytochrome P450 inhibitors (diethyl dithiocarbamate, ketoconazole and grapefruit juice) on the pharmacokinetics of all-trans-retinoic acid.
2004
Diethyl dithiocarbamate (DEDTC) has been reported to be a more powerful inhibitor of all-trans-retinoic acid (ATRA) in vitro metabolism than the well-established cytochrome P450 (CYP) inhibitor ketoconazole (KC). In recent years grapefruit juice (GJ) has been shown to be able to increase the oral bioavailability of several drugs by inhibiting intestinal CYP. This study investigated the in vivo effect of these CYP inhibitors on the pharmacokinetics of ATRA. The latter was administered to rats as a constant-rate intravenous (i.v.) infusion (0.48 mg h(-1) kg(-1)) during 10 h and orally (1.6 mg kg(-1)). DEDTC (320 mg kg(-1) x 2 i.v., 6.4 and 32 mg kg(-1) per os (p.o.)) did not change the ATRA c…
Effect of the Game Design, the Goal Type and the Number of Players on Intensity of Play in Small-Sided Soccer Games in Youth Elite Players
2015
Abstract The aim of this study was to compare the effects of game design modification, the type of the goal and the number of players on the intensity of play in small-sided soccer games (SSGs) in youth elite players. Twenty young soccer players (age 13.7 ± 0.5 years, body mass 57.4 ± 7.8 kg, body height 1.67 ± 7.8 m, maximal heart rate 201.1 ± 8.2 beats/min) performed three types of SSGs (possession play (PP) vs. regular goals (RG) vs. small goals (SG)) in both four-a-side and six-a-side formats. The heart rate responses were recorded and analysed as an indicator of the intensity of play. The four-a-side format obtained higher intensity of play than six-a-side for PP (p<0.05), but not f…
High-energy monitoring of NGC 4593 II. Broad-band spectral analysis: testing the two-corona model
2019
It is widely believed that the primary X-ray emission of AGN is due to the Comptonisation of optical-UV photons from a hot electron corona, while the origin of the 'soft-excess' is still uncertain and matter of debate. A second Comptonisation component, called warm corona, was therefore proposed to account for the soft-excess, and found in agreement with the optical-UV to X-ray emission of a sample of Seyfert galaxies. In this context, we exploit the broadband XMM-Newton and NuSTAR simultaneous observations of the Seyfert galaxy NGC 4593 to further test the so called "two corona model". The NGC 4593 spectra are well reproduced by the model, from the optical/UV to the hard X-rays. Moreover, …
El fracaso de los proyectos de reforma en el virreinato peruano de principios del siglo XVIII. Las propuestas de Carmine Nicola Caracciolo, príncipe …
2021
Desde hace algunas décadas, una nueva corriente historiográfica ha dirigido su atención a las transformaciones que, en los ámbitos social, político y militar, impulsó el gobierno borbónico en las primeras décadas del siglo XVIII. Aunque en gran medida no tuvieron éxito, las reformas promovidas en las dos primeras décadas entre la Península Ibérica, Sicilia, Nueva España y Perú ponen de relieve un importante primer intento de hacer más funcional el gobierno de la Monarquía. Este artículo tiene como objetivo analizar las propuestas de las reformas que Carmine Nicola Caracciolo elaboró durante su mandato como Virrey del Perú (1716-1721). En particular, se reflexionará sobre aquellas propuestas…
«Viva el señor San Antonio, pues que tanto nos ampara»: los santos y su representación en la literatura popular de los siglos XVIII y XIX
2016
En la Edad Moderna la religión impregnaba la vida cotidiana, y los santos eran personajes comunes a los que recurrir en caso de necesidad. Las hagiografías, desde el ámbito oficial, difundían la fama de estas figuras, pero también había una notable circulación oral y escrita de literatura popular religiosa (sobre todo pliegos de cordel y gozos) que los daba a conocer en todos los ámbitos sociales. Primero, esbozaremos las características generales de la santidad en la literatura popular valenciana del XVIII, y después nos centraremos en el caso de la Beata Inés de Benigànim, de devoción local y prolongada en el tiempo (siglos XVII a XX). A través de estos textos podremos comprender la conce…

Les syndicalistes confédérées et la guerre d’Espagne
2022
En juillet 1936, au moment du coup d’État franquiste, la France vit au rythme des dernières grèves victorieuses et des premiers départs en congés payés. Malgré cette ambiance joyeuse, de nombreuses similitudes contribuent à faire de la tragédie espagnole une affaire française. Au niveau syndical, l’Unión General de Trabajadores (UGT) espagnole et la Confédération générale du travail (CGT) française (réunifiée depuis mars 1936) ont connu des évolutions parallèles. Elles ont toutes deux contrib...
Effects of an eccentric training programme on hamstring strain injuries in women football players
2015
Summary Study aim: to test the hypothesis that an eccentric training programme applied on women football players would reduce the hamstring injury rate by improving thigh muscle balance and, particularly, hamstring strength. Material and methods: three football teams were recruited for this randomised controlled trial. They played in the first and second divisions in Spain. Players were randomised within clubs either to the intervention (eccentric exercises, n = 22) or control (control exercises, n = 21) groups, and randomisation was stratified according to previous history of thigh strains. The eccentric programme was divided into 3 phases, and each phase was composed of 7 weeks. Complianc…
IEEE Std. 1459 power quantities ratio approaches for simplified harmonic emissions assessment
2018
The paper investigates the suitability of using power ratio parameters for harmonic emissions assessment at the point of common coupling (PCC). The study is carried out starting from the IEEE Std. 1459-2010 apparent power decomposition, where power factors are defined for evaluating line utilization and harmonic pollution levels. In addition, the study investigates the behavior of new parameters, which are expressed in terms of ratio between IEEE Std. 1459-2010 power quantities. The study is carried out for both single-phase and three-phase case, also considering the presence of capacitors. ? 2018 IEEE.
