Analysis of the critical moments in the League ACB 2007-2008

The aim of this paper was to identify the variables that determine winning or losing in the critical moments of the basketball games. A total of forty one critical moments were analyzed, corresponding to 30 games of the regular season from the Spanish Professional League (ACB, season 2007-2008). Games were selected according to the definition of critical moments (described in the available literature), which corresponded to overtime and the last 5 minutes of games with score differences equal or below to six points. The results revealed better values in the winners in defensive rebounds and successful free-throws

Análisis de las estadísticas discriminantes en jugadores de baloncesto según su puesto específico, en las finales de las competiciones europeas (1988-2006). Diferencias entre jugadores titulares y suplentes

El objetivo del presente estudio ha sido identificar las diferencias que se observan en jugadores de baloncesto, en situación de juego, en función del puesto específico (bases, aleros y pivots), diferenciando entre jugadores titulares y suplentes. Los datos utilizados para el análisis fueron las variables estadísticas individuales de todas las finales de las tres competiciones europeas de clubes  celebradas entre las temporadas 1987-88 y 2005-06. El análisis de los resultados se realizó a través de un análisis discriminante, obteniendo una función discriminante y unos coeficientes canónicos (CCE). Los jugadores titulares se diferenciaron por posición en los rebotes ofensivos (CCE = –0,57), tapones (CCE = –0,52), lanzamientos de 3 puntos convertidos (CCE = 0,51) y fallados (CCE = 0,37). Estos resultados señalan a los bases titulares como los jugadores titulares más importantes dentro de la  estructura colectiva de un equipo. En el caso de los jugadores suplentes, las variables discriminantes encontradas fueron los tapones (CCE = 0,36), los rebotes defensivos (CCE = 0,31) y los lanzamientos de 2 puntos convertidos (CCE = 0,31). Dichos resultados permiten identificar a los pivots suplentes como los suplentes más importantes en la estructura colectiva del equipo. Los resultados presentados pueden ser utilizados como datos a tener en cuenta en el proceso de selección de jugadores en la formación de los equipos o bien en la dirección de los jugadores durante los entrenamientos y la competición

Anàlisi de les estadístiques discriminants en jugadors de bàsquet segons el seu lloc específic, a les finals de les competicions europees (1988-2006). Diferències entre jugadors titulars i suplents

L’objectiu del nostre estudi ha estat identificar les diferències que s’observen en jugadors de bàsquet, en situació de joc, en funció del lloc específic (bases, alers i pivots), tot diferenciant entre jugadors titulars i suplents. Les dades utilitzades per a l’anàlisi van ser les variables estadístiques individuals de totes les finals de les tres competicions europees de clubs celebrades entre les temporades 1987-88 i 2005-06. L’anàlisi dels resultats es va realitzar a través d’una anàlisi discriminant, que va obtenir una funció discriminant i uns coeficients canònics (CCE). Els jugadors titulars es van diferenciar per posició en els rebots ofensius (CCE = –0,57), taps (CCE = –0,52), llançaments de 3 punts convertits (CCE = 0,51) i fallats (CCE = 0,37). Aquests resultats assenyalen els bases titulars com els jugadors titulars més importants dins l’estructura col·lectiva d’un equip. En el cas dels jugadors suplents, les variables discriminants trobades van ser els taps (CCE = 0,36), els rebots defensius (CCE = 0,31) i els llançaments de 2 punts convertits (CCE = 0,31). Aquests resultats permeten identificar els pivots suplents com els suplents més importants en l’estructura col·lectiva de l’equip. Els resultats presentats poden ser utilitzats com a dades a tenir en compte en el procés de selecció de jugadors en la formació dels equips o bé en la direcció dels jugadors durant els entrenaments i la competició

Initial screening of poly(ethylene glycol) amino ligands for affinity purification of plasmid DNA in aqueous two-phase systems

Gene therapy and DNA vaccination are among the most expected biotechnological and medical advances for the coming years. However, the lack of cost-effective large-scale production and purification of pharmaceutical-grade plasmid DNA (pDNA) still hampers their wide application. Downstream processing, which is mainly chromatography-based, of pDNA remains the key manufacturing step. Despite its high resolution, the scaling-up of chromatography is usually difficult and presents low capacity, resulting in low yields. Alternative methods that are based on aqueous two-phase systems (ATPSs) have been studied. Although higher yields may be obtained, its selectivity is often low. In this work, modified polymers based on poly(ethylene glycol) (PEG) derivatisation with amino groups (PEGamine) or conjugation with positively charged amino acids (PEGlysine, PEGarginine, and PEGhistidine) were studied to increase the selectivity of PEGdextran systems towards the partition of a model plasmid. A two-step strategy was employed to obtain suitable pure formulations of pDNA. In the first step, a PEGdextran system with the addition of the affinity ligand was used with the recovery of the pDNA in the PEG-rich phase. Then, the pDNA was re-extracted to an ammonium-sulphate-rich phase in the second step. After removing the salt, this method yielded a purified preparation of pDNA without RNA and protein contamination.Thanks are due to the Fundação para a Ciência e Tecnologia (FCT, Portugal) for financial support to the NMR Portuguese network (PTNMR, Bruker Avance III 400-Univ.

Publisher Copyright: © 2022 The Author(s)In this work, we present K- and L- shell fluorescence yield values of the full isonuclear sequence of Fe ions, using a state-of-the-art multiconfiguration Dirac–Fock approach. These results may be of importance for spectral fitting and plasma modeling, both in laboratory and astrophysical studies, where Fe is an important benchmark element. The K-shell fluorescence yields were found to be very similar up to the removal of 14 electrons.publishersversionpublishe

X-ray lines from photon excitation were measured in selected elements from Mg to Cu using a high-resolution double-crystal X-ray spectrometer with a proportional counter, and the (Formula presented.) intensity ratio for each element was obtained, after correcting for self-absorption, detection efficiency, and crystal reflectance. This intensity ratio increases rapidly from Mg to Ca but, in the (Formula presented.) elements region, the increase becomes slower. This is related to the intensity of the (Formula presented.) line involving valence electrons. The slow increase of this ratio in the (Formula presented.) elements region is thought to be due to the correlation between (Formula presented.) and (Formula presented.) electrons. Moreover, the chemical shifts, FWHM, asymmetry indices, and (Formula presented.) intensity ratios of the Cr compounds, due to different valences, were also investigated using the same double-crystal X-ray spectrometer. The chemical effects were clearly observed, and the (Formula presented.) intensity ratio was found to be compound-dependent for Cr.publishersversionpublishe

Structure of Kα1,2 - And Kβ1,3 -emission x-ray spectra for Se, Y, and Zr

UID/FIS/04559/2020 UID/MULTI/04046/2020 Project No. PTDC/FIS-AQM/31969/20 Grant No. 2017/25/B/ST2/00901The Kα and Kβ x-ray spectra of Se, Y, and Zr were studied experimentally and theoretically in order to obtain information on the Kα1 line asymmetry and the spin doublet in Kβ1,3 diagram lines. Using a high-resolution antiparallel double-crystal x-ray spectrometer, we obtained the line shapes, that is, asymmetry index and natural linewidths. We found that the corrected full width at half maximum of the Kα1 and Kα2 lines as a function of Z is in good agreement with the data in the literature. Furthermore, satellite lines arising from shake-off appear in the low-energy side of the Kα1 and Kα2 lines in Se but, in Y and Zr, it was very difficult to identify the contribution of the shake process to the overall lines. The Kβ1,3 natural linewidth of these elements was also corrected using the appropriate instrumental function for this type of x-ray spectrometer, and the spin doublet energies were obtained from the peak positions. The corrected full width at half maximum (FWHM) of the Kβ1 x-ray lines increases linearly with Z, but this tendency was found to be, in general, not linear for Kβ3 x-ray lines. This behavior may be due to the existence of satellite lines originated from shake processes. Simulated line profiles, obtained using the multiconfiguration Dirac-Fock formalism, accounting for radiative and radiationless transitions and shake-off processes, show a very good agreement with the high-resolution experimental spectra.publishersversionpublishe
