Preferential oxidation of CO on a La-Co-Ru perovskite-type oxide catalyst
A Ru-containing perovskite-type oxide La(Co,Ru)O3 of nominal composition LaCo0.8Ru0.2O3 was prepared by ultrasonic spray combustion and tested for the preferential oxidation of CO (PROX). EXAFS indicated that Ru adopted the coordination environment of Co in LaCoO3 while Co was present as LaCoO3 and Co3O4. PROX activity was replaced by CO hydrogenation activity above 250 °C. Short oxidation at 500 °C between temperature programmed reaction ramps did not restore the initial La(Co,Ru)O3 structure but generated a catalyst with improved PROX activity compared to the initial La(Co,Ru)O3. Under reductive PROX conditions the material experienced structural changes that improved its overall catalytic activity only if the catalyst was oxidized after each temperature programmed ramp.Spanish Ministry of Research (Project CTQ2014-60524-R)University of Seville for a scholarship for R.P. and the Swiss National Science Foundation (SNF)(Project nr. 200021_159568

En este Trabajo Fin de Grado se ha realizado un estudio teórico sobre el
Síndrome de Down y la motricidad gruesa, en el cual se presenta una aproximación
conceptual que da lugar al paso de las terminologías y a los cuatro tipos de
discapacidades, también se muestran los antecedentes históricos donde se explica el
surgimiento de este síndrome hasta la actualidad, viendo los diferentes tipos de
alteraciones cromosómicas que se puede exteriorizar. Además, se detallan algunas
características del desarrollo evolutivo que presentan los sujetos con este síndrome
dentro de los cuatro ámbitos del desarrollo.
Por otro lado, se presentan algunas teorías generales sobre la conducta motriz y

nacimiento hasta los 6 años y se profundiza en el concepto de las habilidades motrices.
Asimismo, se presentan aspectos importantes acerca del juego, de la actividad física
relacionada con el Síndrome de Down y algunas pautas significativas para poder
plantear las actividades adecuadamente.
Finalmente, se ha realizado una propuesta de intervención con el fin de llegar a
incluir dentro del aula de psicomotricidad al alumnado con Síndrome de Down ya que
trabajaban de manera aislada con respecto a los alumnos que trabajan en el aula
ordinaria. Por lo tanto, se vio la necesidad de crear una propuesta de intervención para
poder ayudar a esas niñas para que pudiesen desarrollar las habilidades motrices básicas
mediante unas actividades más dinámicas que se realizarían conjuntamente con todos
sus compañeros del aula.Es aquest Treball Fi de Grau s’ha realitzat un estudi teòric sobre el Síndrome de

Finalment, s’ha realitzat una proposta d’intervenció amb la finalitat d’arribar a
incloure dins de l’aula de psicomotricitat al alumnat amb Síndrome de Down ja que
treballaven de manera aïllada respecte als alumnes que treballaven a l’aula ordinària.
Per tant, es va veure la necessitat de crear una proposta d’intervenció per a poder ajudar
a aquelles xiquetes perquè pogueren desenvolupar les habilitats motrius bàsiques
mitjançant unes activitats més dinàmiques que es realitzarien conjuntament amb tots els
seus companys de l’aula.In this End of Grade Work a theoretical study has been conducted on Down
syndrome and gross motor skills, presenting a conceptual approach that leads to the
passage of terminologies and the four types of disabilities. It also shows the historical
antecedents by explaining the emergence of this syndrome to the present day, seeing the
different types of chromosomal alterations which can be externalized. In addition, some
characteristics of the evolutionary development which are presented by the person with
this syndrome within the four areas of development are detailed.
On the other hand, there are some general theories about motor behavior and
human development, it explains the growth and development of children from birth to
age 6 and deepens the concept of motor skills. There are also important aspects about
the game, about the physical activity related to Down syndrome and some significant
guidelines for being able to raise activities appropriately.
Finally, a proposal for intervention has been made in order to include in the
psychomotricity classroom students with Down syndrome since they have been working
in isolation with respect to students who work in the ordinary classroom. Therefore,
there was a need to create an intervention proposal in order to help these girls so that
they could develop basic motor skills through more dynamic activities that would be
carried out together with all his classmates.Educació
Economic and Humanistic Burden of Moderate and Severe Hemophilia A and B in Spain: Real-World Evidence Insights from the CHESS II Study
Background: Hemophilia is a congenital disorder characterized by deficiency or absence of clotting factor VIII in hemophilia A (HA) or clotting factor IX in hemophilia B (HB), resulting in frequent, repeated, and prolonged spontaneous or traumatic bleeding into joints or soft tissue. Severity is classified by the patient’s baseline level of clotting factor activity as mild (>5%-40%), moderate (1%-5%), or severe (<1%). In Spain, there is limited information on the societal economic burden of disease. Objective: To estimate the economic and humanistic burden of disease in adult patients with non-inhibitor moderate and severe HA and HB in Spain. Methods: Spanish data from the CHESS II study (2018-2020) on patients’ clinical characteristics, health-related quality of life (HRQoL) and hemophilia-related healthcare resource utilization were analyzed. Economic burden was determined by estimating condition-related annual per-patient direct (medical and nonmedical) and indirect costs, stratified according to hemophilia type and severity and presented as 2022 Euros. HRQoL was assessed via the EQ-5D-5L. Results: Of 341 patients in the Spanish CHESS II cohort, 288 patients met the inclusion criteria: 181 had HA (37% [n = 66] moderate and 63% [n=115] severe) and 107 had HB (26% [n = 28] moderate and 74% [n = 79] severe). Mean annual direct cost was higher in HB than in HA, and higher in severe than in moderate patients, resulting in an annual cost/patient of €17 251 (moderate HA), €17 796 (moderate HB), €116 767 (severe HA) and €206 996 (severe HB). The main direct cost component in all groups except moderate HA was factor replacement therapy. Mean per-patient indirect cost was €4089 (moderate HA), €797 (moderate HB), €8633 (severe HA) and €8049 (severe HB). Finally, the mean total cost (direct and indirect) for moderate and severe patients were €91 017 (HA) and €163 924 (HB). EQ-5D-5L [SD] scores were lower in patients with severe HA (0.77 [0.18]) and severe HB (0.70 [0.22]) compared with patients with moderate HA (0.81 [0.15]) and moderate HB (0.86 [0.17]). Conclusions: Independently of the type of hemophilia, greater condition severity was associated with increased costs and a decrease in HRQoL
Superiority of the new sex-adjusted models to remove the female disadvantage restoring equity in liver transplant allocation
Background and Aims: Model for End-stage Liver Disease (MELD) and MELDNa are used worldwide to guide graft allocation in liver transplantation (LT). Evidence exists
that females are penalized in the present allocation systems. Recently, new sex-adjusted
scores have been proposed with improved performance respect to MELD
and MELDNa. GEMA-Na,
MELD 3.0, and sex-adjusted
MELDNa were developed to
improve the 90-day
dropout prediction from the list. The present study aimed at evaluating
the accuracy and calibration of these scores in an Italian setting.
Methods: The primary outcome of the present study was the dropout from the list up to
90 days because of death or clinical deterioration. We retrospectively analysed data from
855 adults enlisted for liver transplantation in the Lazio region (Italy) (2012–2018).
Ninety-day
prediction of GEMA-Na,
MELD 3.0 and sex-adjusted
MELDNa with respect to MELD
and MELDNa was analysed. Brier score and Brier Skill score were used for accuracy, and
the Greenwood-Nam-
D'Agostino
test was used to evaluate the calibration of the models.
Results: GEMA-Na
(concordance = .82, 95% CI = .75–.
89), MELD 3.0 (concordance =
.81, 95% CI = .74–.
87) and sex-adjusted
MELDNa (concordance = .81, 95% CI = .74–.88)
showed the best 90-day
dropout prediction. GEMA-Na
showed a higher increase
in accuracy with respect to MELD (p = .03). No superiority was shown with respect
to MELDNa. All the tested scores showed a good calibration of the models. Using
GEMA-Na
instead of MELD would potentially save one in nine dropouts and could
save one dropout per 285 patients listed
Search for Neutrinoless Double-Beta Decay of Te with CUORE-0
We report the results of a search for neutrinoless double-beta decay in a
9.8~kgyr exposure of Te using a bolometric detector array,
CUORE-0. The characteristic detector energy resolution and background level in
the region of interest are FWHM and ~counts/(keVkgyr), respectively. The
median 90%~C.L. lower-limit sensitivity of the experiment is and surpasses the sensitivity of previous searches. We find
no evidence for neutrinoless double-beta decay of Te and place a
Bayesian lower bound on the decay half-life, ~ at 90%~C.L. Combining CUORE-0 data with the 19.75~kgyr
exposure of Te from the Cuoricino experiment we obtain at 90%~C.L.~(Bayesian), the most stringent
limit to date on this half-life. Using a range of nuclear matrix element
estimates we interpret this as a limit on the effective Majorana neutrino mass,

Analysis Techniques for the Evaluation of the Neutrinoless Double-Beta Decay Lifetime in Te with CUORE-0
We describe in detail the methods used to obtain the lower bound on the
lifetime of neutrinoless double-beta () decay in Te and
the associated limit on the effective Majorana mass of the neutrino using the
CUORE-0 detector. CUORE-0 is a bolometric detector array located at the
Laboratori Nazionali del Gran Sasso that was designed to validate the
background reduction techniques developed for CUORE, a next-generation
experiment scheduled to come online in 2016. CUORE-0 is also a competitive
decay search in its own right and functions as a platform to
further develop the analysis tools and procedures to be used in CUORE. These
include data collection, event selection and processing, as well as an
evaluation of signal efficiency. In particular, we describe the amplitude
evaluation, thermal gain stabilization, energy calibration methods, and the
analysis event selection used to create our final decay search
spectrum. We define our high level analysis procedures, with emphasis on the
new insights gained and challenges encountered. We outline in detail our
fitting methods near the hypothesized decay peak and catalog
the main sources of systematic uncertainty. Finally, we derive the
decay half-life limits previously reported for CUORE-0,
yr, and in combination with the Cuoricino
limit, yr.Comment: 18 pages, 18 figures. (Version 3 reflects only minor changes to the

Measurement of the Two-Neutrino Double Beta Decay Half-life of Te with the CUORE-0 Experiment
We report on the measurement of the two-neutrino double beta decay half-life
of Te with the CUORE-0 detector. From an exposure of 33.4 kgy of
TeO, the half-life is determined to be = [8.2 0.2
(stat.) 0.6 (syst.)] 10y. This result is obtained after a
detailed reconstruction of the sources responsible for the CUORE-0 counting
rate, with a specific study of those contributing to the Te
neutrinoless double beta decay region of interest.Comment: Corrected typo in section 9: 3.43E5 Bq/kg should have read 3.43E-5
