Inclusive measurements of the K+- and p / anti-p production in hadronic Z0 decays
1995
This analysis, based on a sample of 170000 hadronic Z0 decays, provides a measurement of the K± and p/View the MathML source differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K± and p/View the MathML source per hadronic event were found to be: NK = 2.26 ± 0.18 and Np = 1.07 ± 0.14. The positions ξ* of the maxima of the differential cross sections as a function of ξ = ln(1/xp) for K± and p/View the MathML source were determined to be 2.63 ± 0.07 and 2.96 ± 0.16 respectively. A comparison of the ξ* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation wit…
Production of charged particles, K0(s), K+-, p and Lambda in Z --> b anti-b events and in the decay of b hadrons
1995
sample of events enriched in bb̄ quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of Ks0, K±, p(p̄), Λ(View the MathML source) and of charged particles in bb̄ events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in bb̄ events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between bb̄ events and light quark (uū, …
Measurement of CP asymmetry in D 0 → K - K + and D 0 → π - πdecays
2014
Time-integrated $CP$ asymmetries in $D^0$ decays to the final states $K^- K^+$ and $\pi^- \pi^+$ are measured using proton-proton collisions corresponding to $3\mathrm{\,fb}^{-1}$ of integrated luminosity collected at centre-of-mass energies of $7\mathrm{\,Te\kern -0.1em V}$ and $8\mathrm{\,Te\kern -0.1em V}$. The $D^0$ mesons are produced in semileptonic $b$-hadron decays, where the charge of the accompanying muon is used to determine the initial flavour of the charm meson. The difference in $CP$ asymmetries between the two final states is measured to be \begin{align} \Delta A_{CP} = A_{CP}(K^-K^+)-A_{CP}(\pi^-\pi^+) = (+0.14 \pm 0.16\mathrm{\,(stat)} \pm 0.08\mathrm{\,(syst)})\% \ . \nonu…
Síndrome de déficit de testosterona y disfunción eréctil
2010
OBJETIVOS Analizar la relacion entre el sindrome de deficit de testosterona (SDT) y la disfuncion erectil y sus implicaciones diagnosticas y terapeuticas. METODOS Revision bibliografica mediante la base de datos de Pubmed de la US National Library of Medicine. RESULTADOS La real prevalencia del SDT es desconocida, debido a la falta de criterios diagnosticos uniformes en cuanto a que fraccion de testosterona debe medirse (total, libre o biodisponible) y cuales deben ser los valores diagnosticos. A pesar de ello, se estima que entre un 5-15% de varones con disfuncion erectil presentan niveles sericos disminuidos de testosterona. Existe una solida base experimental que demuestra que la testost…
Bartomeu de Tresbens, metge i astròleg de Pere el Cerimomiós : aproximació biogràfica i diplomatari
2019
Aproximació biogràfica a Bartomeu de Tresbens, físic i astròleg al servei del rei Pere el Cerimoniós i del seu fill l'infant Joan, futur Joan I el Caçador. Ho fem a partir del conjunt de la documentació sobre aquest personatge que fins ara ha estat descoberta als arxius, fonamentalment a l'Arxiu de la Corona d'Aragó, i també a partir de les notícies que apareixen en el conjunt de les seves obres sobre astrologia. Hem situat Tresbens en els seus orígens occitans, així com en el context de les activitats econòmiques, polítiques i socials durant el temps que el tenim documentat en terres de la Corona d'Aragó, mostrant l'home que hi ha al darrere de la més important obra astrològica en català. …
Gennadios Scholarios and the Church of the Holy Apostles
2020
The article tests the established view that Gennadios Scholarios, the first patriarch of Constantinople after the 1453 Conquest, used the church of the Holy Apostles in Constantinople as the seat of the Patriarchate for a few months in 1454 before moving to the building complex of the Pammakaristos monastery. After pointing out that all the sources that narrate the story of the installation of the Patriarchate in the famous Byzantine church date from the 16th century or later, the author examines sources contemporary with the events, including texts written by Scholarios himself. The aim of the article is to show that Scholarios officiated occasionally in the Holy Apostles and managed to sa…
La diplomacia de la Corona de Aragón durante la Guerra de los Dos Pedros (1356-1362): Granada y Fez
2020
El presente trabajo ofrece nuevos datos para el estudio de las relaciones diplomáticas de la Corona de Aragón con los países musulmanes en un período de tiempo concreto, de 1356 a 1362, en el marco de la Guerra de los Dos Pedros. En concreto, este estudio centra su atención en Granada y Fez, las principales potencias musulmanas del Mediterráneo occidental, cuyo apoyo trató de lograr el rey Pedro de Aragón a fin de combatir al rey de Castilla.

Return Visits: The European Background of Transcultural Life Writing
2013
In this article I read autobiographies by East Europeans who immigrated to Canada in connection with the Second World War as examples of transcultural life writing. My focus on the representation of return visits of these loyal Canadian citizens to their country of origin after 1989 reveals the underlying intention of relating the experience of life in a multicultural democratic society to the emergence of a new political consciousness in Eastern Europe. In my analysis I distinguish four types of concerns which try to bridge the past of their childhood experiences with the formation of a transcultural life in the 21st century: 1. Anna Porter’s return visit to Hungary for family reunion and …
Capilaridad de la manufactura textil en la Plana de Castelló. El caso de Onda en el siglo XV
2010
Onda, a locality with an oscillating population between 300 and 600 dwellings in the 15th century and with Moslems and Jews in the local work, becomes a new piece of the puzzle that lets us see the capillarity of the wool textile manufacture in “La Plana de Castelló”. This capillarity can be seen in the production of clothes, just like in the raw material trade or in the movement of craftsmen. To approach this situation we have basically used the series of documents of the judge of the village kept in the “Archivo del Reino de Valencia”.<br><br>Onda, localidad con un volumen demográfico oscilante entre 300-600 fuegos en el transcurso del siglo XV, con presencia de mudéjares y ju…
Ultrastructure and Organization of the Cytoskeleton in Oxymonas, an Intestinal Flagellate of Termites
1997
ABSTRACT. Oxymonas has the characteristic structures and organization of other oxymonads including two separated pairs of basal bodies/flagella, a preaxostylar lamina, a paracrystalline axostyle, and an absence of mitochondria and Golgi. Like other Oxymonadinae genera it possesses a long proboscis, the rostellum which is terminated by the holdfast. Like the genera Pyrsonympha and Streblomastix, Oxymonas possesses a holdfast which permits it to attach to the cuticle of the termite hind-gut. This holdfast is subdivided into rhizoids and is filled with microfilaments. The rostellum is variable in length and contains two distinct microtubular bundles. One bundle is composed of convoluted microt…
