El Mobile Learning en el aula de ELE. Propuestas para el alumnado italófono
Los dispositivos móviles se han convertido en una herramienta irrenunciable en la vida de los seres humanos, principalmente como instrumento para estar en contacto con cualquier persona en cualquier lugar y en cualquier momento. La introducción de los smartphone y las tabletas en las aulas de Educación Secundaria favorece la motivación y la autonomía del alumnado, puesto que las aplicaciones digitales (Apps) son el mundo en el que nace y vive. Sin embargo, el concepto de Mobile Learning se puede aplicar tanto al aula de lengua y literatura para hispanohablantes como al aula de español para extranjeros, empleando el móvil no como sustituto del material en papel, sino como elemento que fomenta las habilidades comunicativas. Teniendo en cuenta la utilidad de las app para dispositivos móviles en las aulas de Español como Lengua Extranjera (ELE), en el presente trabajo se desarrolla una propuesta didáctica desde el área de lengua y literatura española para el alumnado italófono: estos estudiantes constituyen un grupo particular de aprendices de español ya que, como los dos idiomas se parecen, surgen dificultades inesperadas al descubrir las divergencias durante el estudio de la lengua
Climate Mitigation and Adaptation Strategies for Roofs and Pavements. A Case Study at Sapienza University Campus
The progressively emerging concept of urban resilience to climate change highlights the
importance of mitigation and adaptation measures, and the need to integrate urban climatology
in the design process, in order to better understand the multiple effects of combined green and
cool technologies for the transition to climate responsive and thermally comfortable urban open
spaces. This study focuses the attention on selected mitigation and adaptation technologies; two
renovation scenarios were designed and modeled according to the minimal intervention criterion. The
study pays attention to the effect on surface temperature and physiological equivalent temperature
(PET) of vegetation and high albedo materials characterizing the horizontal boundaries of the site.
The Sapienza University campus, a historical site in Rome, is taken as a case study. These results
highlight the importance of treed open spaces and the combination of permeable green pavements
associated with cool roofs as the most effective strategy for the mitigation of summer heatwaves and
the improvement of outdoor thermal comfort

Dynamic changes and prognostic value of pulmonary congestion by lung ultrasound in acute and chronic heart failure: a systematic review
Aims:
Pulmonary congestion is an important finding in patients with heart failure (HF) that can be quantified by lung ultrasound (LUS). We conducted a systematic review to describe dynamic changes in LUS findings of pulmonary congestion (B-lines) in HF and to examine the prognostic utility of B-lines in HF.
Methods and results:
We searched online databases for studies conducted in patients with chronic or acute HF that used LUS to assess dynamic changes or the prognostic value of pulmonary congestion. We included studies in adult populations, published in English, and conducted in ≥25 patients. Of 1327 identified studies, 13 (25–290 patients) met the inclusion criteria: six reported on dynamic changes in LUS findings (438 patients) and seven on the prognostic value of B-lines in HF (953 patients). In acute HF, B-line number changed within as few as 3 h of HF treatment. In acute HF, ≥15 B-lines on 28-zone LUS at discharge identified patients at a more than five-fold risk for HF readmission or death. Similarly, in ambulatory patients with chronic HF, ≥3 B-lines on five- or eight-zone LUS marked those at a nearly four-fold risk for 6-month HF hospitalization or death.
Conclusions:
Lung ultrasound findings change rapidly in response to HF therapy. This technique may represent a useful and non-invasive method to track dynamic changes in pulmonary congestion. Furthermore, residual congestion at the time of discharge in acute HF or in ambulatory patients with chronic HF may identify those at high risk for adverse events
Interferon free antiviral treatment of chronic hepatitis C in patients affected by β-thalassemia major
Chronic hepatitis C (CHC) significantly affects the prognosis
of liver disease [1] and health related quality of life (HRQOL)
in patients with β-thalassemia major [2, 3]. CHC cure is a
crucial event in the prognosis of the disease, since prevents
fibrosis progression, decreases the risk of hepatocellular carcinoma (HCC), and improves survival. Standard antiviral
therapy with Pegylated Interferon (PEG-IFN) and Ribavirin
(RBV) has long been the standard of care, despite its limited
efficacy and increased ribavirin induced hematological adverse events in thalassemic patients [4]. Recently, several novel highly effective direct antiviral agents (DAAs) have been
approved for HCV treatment, with impressive cure rates,
higher than 90%, after 8–12 weeks of therapy and mild adverse events [5], but there are no published reports
documenting the efficacy, safety and impact on QOL of available interferon-free antiviral regimens in patients with βthalassemia majo
Sharp Hardy inequalities in the half space with trace remainder term
In this paper we deal with a class of inequalities which interpolate the
Kato's inequality and the Hardy's inequality in the half space. Starting from
the classical Hardy's inequality in the half space \rnpiu
=\R^{n-1}\times(0,\infty), we show that, if we replace the optimal constant
with a smaller one , , then we can add an extra trace-term equals to that one that appears in the
Kato's inequality. The constant in the trace remainder term is optimal and it
tends to zero when goes to , while it is equal to the optimal
constant in the Kato's inequality when

Evaluation of 4 Outcomes Measures in Microtia Treatment: Exposures, Infections, Aesthetics, and Psychosocial Ramifications.
BackgroundIn craniofacial microsomia, microtia and canal atresia pose formidable reconstructive challenges. We review our institutional experience in treating microtia and atresia to identify variables associated with 4 outcomes measures: complications, surgical revisions, aesthetic outcomes, and psychosocial function.MethodsCraniofacial microsomia patients treated at the University of California Los Angeles Craniofacial Clinic between 2008 and 2014 greater than 13 years of age (n = 68) were reviewed for microtia and atresia treatment and outcomes.ResultsIn total, 91.2% of patients diagnosed with craniofacial microsomia presented with microtia, affecting 75 ears. Both a male and right-sided predominance were observed. Fifty-six patients (90.3%) underwent autologous external ear reconstruction at an average age of 8.5 years. Age, type of incision, and size of cartilage framework did not predict total number of surgeries or complications. Severity of ear anomalies correlated with increased number of surgeries (P < 0.001) and decreased aesthetic outcomes (P < 0.001) but not complications. In total, 87.1% of patients with microtia had documented hearing loss, of which the majority were conductive and 18.5% were mixed sensorineural and conductive. Hearing deficits were addressed in 70.4% of patients with external hearing aids, bone anchored hearing aids, or canaloplasty. Of all variables, improvement of psychosocial function was correlated only to hearing loss treatment of any type (P = 0.01).ConclusionsOn evaluation of surgical and patient characteristics, severity of microtia predicted the total number of surgical revisions performed and aesthetic ratings. In addition, we found that the only factor that correlated with improved patient and parent-reported psychosocial outcomes was treatment of hearing loss
