The Nature of the Secondary Star in the Black Hole X-Ray Transient V616 Mon (=A0620-00)
We have used NIRSPEC on Keck II to obtain -band spectroscopy of the low
mass X-ray binary V616 Mon (= A062000). V616 Mon is the proto-typical soft
x-ray transient containing a black hole primary. As such it is important to
constrain the masses of the binary components. The modeling of the infrared
observations of ellipsoidal variations in this system lead to a derived mass of
11.0 M_{\sun} for the black hole. The validity of this derivation has been
called into question due to the possiblity that the secondary star's spectral
energy distribution is contaminated by accretion disk emission (acting to
dilute the variations). Our new -band spectrum of V616 Mon reveals a
late-type K dwarf secondary star, but one that has very weak CO
absorption features. Comparison of V616 Mon with SS Cyg leads us to estimate
that the accretion disk supplies only a small amount of -band flux, and the
ellipsoidal variations are not seriously contaminated. If true, the derived
orbital inclination of V616 Mon is not greatly altered, and the mass of the
black hole remains large. A preliminary stellar atmosphere model for the
-band spectrum of V616 Mon reveals that the carbon abundance is
approximately 50% of the solar value. We conclude that the secondary star in
V616 Mon has either suffered serious contamination from the accretion of
supernova ejecta that created the black hole primary, or it is the stripped
remains of a formerly more massive secondary star, one in which the CNO cycle
had been active.Comment: 20 pages, 5 figure
Il Percorso Diagnostico Terapeutico Assistenziale del paziente con melanoma metastatico presso l\u2019Azienda Ospedaliera Universitaria Policlinico Paolo Giaccone di Palermo come strumento applicativo della clinical governance
L\u2019evoluzione dello scenario internazionale relativo alla sanit\ue0
identifica cinque specifiche dimensioni come driver del
cambiamento: il sistema, la finanza, le persone, i processi e
la tecnologia. In linea con tali elementi, il patto per la salute
2014-2016 esplicita la necessit\ue0 di una rivisitazione a tutti i
livelli del sistema salute, sia organizzativo che gestionale, con
l\u2019intento di aumentare l\u2019efficienza e l\u2019efficacia, sviluppando
nuovi modelli assistenziali, anche nella logica delle reti
cliniche, dove tra gli \u201cstrumenti\u201d viene identificata l\u2019attivazione
di Percorsi Diagnostico Terapeutico Assistenziali (PDTA). I
percorsi condivisi e codificati per i vari stadi di patologia,
con un sistema di raccolta dei dati clinici che possa
generare gli indicatori di processo e di esito, sono ritenuti
indispensabili per innescare il miglioramento della qualit\ue0
e valutare l\u2019efficacia e l\u2019efficienza. Tenendo conto di queste
premesse, nell\u2019ambito dell\u2019Azienda Ospedaliera Universitaria
Policlinico Paolo Giaccone di Palermo \ue8 stata sviluppata
una progettualit\ue0 al fine di formalizzare e studiare il PDTA
del paziente con melanoma metastatico, identificando il
percorso ideale e descrivendo il percorso applicabile con le
relative leve del cambiamento. Il progetto ha reso evidente
come la gestione consapevole del \u201cprofondo cambiamento\u201d
in essere nelle organizzazioni clinico assistenziali pu\uf2 essere
\u201cgovernata\u201d grazie anche alla \u201cdocumentazione\u201d del proprio
modo di operare in riferimento alle Linee Guida di riferimento
e alle relative raccomandazioni. Il progetto ha reso evidente
inoltre come la sostenibilit\ue0 dei percorsi passa anche
attraverso la definizione di opportuni indicatori, correlati alle
diverse fasi ed attivit\ue0 chiave, da poter monitorare nella \u201cvita
corrente dell\u2019organizzazione\u201d
Resonance line-profile calculations based on hydrodynamical models of cataclysmic variable winds
We present synthetic line profiles as predicted by the models of 2-D line-
driven disk winds due to Proga, Stone & Drew. We compare the model line
profiles with HST observations of the cataclysmic variable IX Vel. The model
wind consists of a slow outflow that is bounded on the polar side by a fast
stream. We find that these two components of the wind produce distinct spectral
features. The fast stream produces profiles which show features consistent with
observations. These include the appearance of the P-Cygni shape for a range of
inclinations, the location of the maximum depth of the absorption component at
velocities less than the terminal velocity, and the transition from absorption
to emission with increasing inclination. However the model profiles have too
little absorption or emission equivalent width. This quantitative difference
between our models and observations is not a surprise because the line-driven
wind models predict a mass loss rate that is lower than the rate required by
the observations. We note that the model profiles exhibit a double-humped
structure near the line center which is not echoed in observations. We identify
this structure with a non-negligible redshifted absorption which is formed in
the slow component of the wind where the rotational velocity dominates over
expansion velocity. We conclude that the next generation of disk wind models,
developed for application to CVs, needs to yield stronger wind driving out to
larger disk radii than do the present models.Comment: LaTeX, 19 pages, to appear in Ap
Uso de Levaduras Activas en Nutrición de Camarón
La acuacultura de camarón es una industria que usa harina de pescado en las dietas, el cual es un ingrediente difícil de obtener a bajo costo y es cada vez más escaso. Es importante encontrar estrategias que ayuden a la nutrición del camarón mediante el uso de ingredientes alternativos que reemplacen o complementen a la harina de pescado y ayuden a desarrollar una industria más amigable para el medio ambiente. Las levaduras se pueden añadir a las dietas para los organismos acuáticos y son un producto microbiano generado por sistemas biotecnológicos o un subproducto de las industrias agroalimentarias. Este estudio determinó el uso potencial de levaduras activas (Candida insectorum, C. parapsilosis, C. sake, C. utilis, Debaryomyces hansenii, Rhodosporidium paludigenum, Saccharomyces cerevisiae, Schizosaccharomyces pombe, y Yarrowia lipolytica) en camarones juveniles y postlarvas de Litopenaeus schmitt, Fenneropenaeus indicus y L. vannamei. Los resultados muestran que las levaduras activas pueden ser empleadas a diferentes dosis como un sustituto parcial de la harina de pescado y/o harina de soya e incorporarse a dietas de camarones juveniles o usarse directamente en dietas para postlarvas. Sin embargo, es necesario realizar estudios que determinen las estrategias más eficientes para que la levadura activa sea ingerida por el camarón
On 4d rank-one N=3 superconformal field theories
We study the properties of 4d N=3 superconformal field theories whose rank is
one, i.e. those that reduce to a single vector multiplet on their moduli space
of vacua. We find that the moduli space can only be of the form C^3/Z_k for
k=1,2,3,4,6, and that the supersymmetry automatically enhances to N=4 for
k=1,2. In addition, we determine the central charges a and c in terms of k, and
construct the associated 2d chiral algebras, which turn out to be exotic N=2
supersymmetric W-algebras.Comment: 24 page
