Peak characteristics of F2 region over Tucumán: Predictions and measurements

Ionosonde measurements obtained at Tucuman are used to check the validity of the International Reference Ionosphere model to predict the maximum electron density of F2 region (NmF2) and its height (hmF2) over this station. Data corresponding to different months and solar activity conditions are considered. CCIR and URSI options are used to model calculations. The results show that, generally, the predictions of hmF2 are better than those of NmF2. Disagreements between predicted and measured NmF2 values are observed and the consequence in the vertical total electron content modeling are stressed.Fil: Ezquer, Rodolfo Gerardo.

The impact of contemplative practices on foreign language anxiety and learning

This study looked at the impact of the integration of contemplative practices on foreign language anxiety, positive and negative affect, self-efficacy, classroom climate, and language learning in students enrolled in an advanced intermediate Spanish language course in the USA. Data included pre- and post-test surveys, exam scores to measure learning outcomes, student interviews, and course evaluations. In the contemplative group, students engaged in brief 10-minute contemplative practices once a week, while the non-contemplative group followed the same syllabus but was not exposed to contemplative practices. Analysis of the data showed no significant differences in foreign language anxiety, self-efficacy or affect between the non-contemplative and contemplative groups at post-test but significantly higher scores on classroom climate measures in the contemplative group. Significantly higher grades were found on course exams for students in the contemplative group. Analysis of the pre-/post-survey data revealed a significant decrease in foreign language anxiety in both groups over the semester but not for affect or self-efficacy. This study extends the existing research on contemplative practices to a new context—affect and learning in foreign language courses

Navigating Stress: Graduate Student Experiences with Contemplative Practices in a Foreign Language Teacher Education Course

The present case study investigates the experience of stress among graduate students, particularly stress related to teaching, their coping strategies, and their experience with contemplative practices integrated into a teacher education course. While there is a significant body of research on contemplative practices in K-12 teacher development, few studies have looked at the integration of contemplative practices in graduate student experiences in higher education. Data for this case study include interviews with 19 graduate students enrolled in foreign language M.A./Ph.D. programs. Results suggest that students’ perceived stress stems from the difficulties of adapting to and balancing new responsibilities and concerns about teaching. To cope with stress, graduate students most commonly rely on emotional support from peers and time management strategies. Students report that participating in contemplative practices together as a class cultivated community, providing them with support, collegiality, interconnectedness, and collaboration as teachers and scholars. The integration of contemplative practices promoted an awareness of the importance of self-care, compassion for self and others, and social and emotional awareness

Un nuovo caso di revisione dopo la sentenza della Corte Costituzionale n. 113 del 2011. Analogie e dissonanze con l'ipotesi tradizionale.

Nella presente tesi partendo da una analisi approfondita del fenomeno del giudicato e delle impugnazioni straordinarie che consentono il suo venire meno e, quindi, la riapertura della sentenza definitiva, si arriva allo studio della sentenza 113 del 2011 della Corte Costituzionale, la quale, nel dichiarare l'illegittimità costituzionale dell'articolo 630 c.p.p., ha introdotto nel nostro ordinamento un nuovo caso di revisione che opere quando il processo già definito con provvedimento di condanna venga impugnato presso e sia ritenuto ingiusto dalla Corte Europea dei diritti dell'uomo, la quale riscontra che vi è stata una violazione di uno dei diritti contenuti nella Convenzione Europea dei diritti dell'uomo, e ritiene che per porre fine a tale violazione e assicurare all'interessato la restituzio in integrum, sia necessaria la riapertura del processo a suo carico

Method for the detection and quantification of analytes using three-dimensional paper-based devices

Described herein are three-dimensional (3-D) paper fluidic devices. The entire 3-D device is fabricated on a support layer formed from a single sheet of material and assembled by folding the support layer. The folded structure may be enclosed in an impermeable cover or package. Chemically sensitive particles may be disposed in the support layer for use in detecting analytes.Board of Regents, University of Texas Syste

Il Registro Regionale Malattie Rare della Toscana

Rare diseases (RDs) are life-threatening or chronically debilitating diseases with a prevalence lower than 5 cases among 10,000. For these conditions there is a lack of scientific information, research, diagnosis, treatment and expert availability. In 2001 the Italian Network for RDs was set up in order to obtain epidemiological information on these diseases. Presidia specifically identified by the Regions for diagnosis/treatment and by the Regional and National Registries are part of the national Network. Some RDs Registries were also created at the regional level. The Tuscany Registry for Rare Diseases (RTMR) is a network of presidia identified by the regional administration. The single presidium refers to a coordination centre for each group of RDs. The "G. Monasterio" Foundation for Medical Research and Public Health, formerly Institute of Clinical Physiology of the CNR, in charge of the Registry management, has produced a protocol, a questionnaire and a software allowing electronic registration of RD cases treated in Tuscany health centres via the Internet. Additionally, the local Register uploads local cases into the National Registry for RDs, coordinated by the Istituto Superiore di Sanit? (ISS). The registration questionnaire is divided in several sections and seeks information on patient, disease, diagnosis, tests performed for diagnosis, besides health condition and treatment. Cases are patients, dead or alive, diagnosed and followed by the Tuscan Presidia of the Regional Health System, including those residing outside the Region, properly diagnosed with one of the RDs included in the 279/2001 Ministerial Decree\u27s list. To ensure privacy, data can only be accessed using a login username and password assigned to each user. Further information is available on the Tuscan Registry for Rare Diseases website: www.rtmr.i

Graphene-Paper-Based Electrodes on Plastic and Textile Supports as New Platforms for Amperometric Biosensing

The possibility of exfoliating graphite into graphene sheets allows the researchers to produce a material, termed “graphene paper” (G-paper), conductive as graphite but more flexible and processable. G-paper is already used for electronic applications, like conductors, antennas, and heaters, outperforming metal conductors thanks to its high flexibility, lightness, chemical stability, and compatibility with polymeric substrates. Here, the effectiveness in the use of G-paper for the realization of electrodes on flexible plastic substrates and textiles, and their applicability as amperometric sensors are demonstrated. The performance of these devices is compared with commercial platforms made of carbon-based inks, finding that they outperform commercial devices in sensing nicotinamide adenine dinucleotide (NADH), a key molecule for enzymatic biosensing; the electrodes can achieve state-of-the-art sensitivity (107.2 μA mm−1 cm−2) and limit of detection (0.6 × 10−6 m) with no need of additional functionalization. Thanks to this property, the stable deposition of a suitable enzyme, namely lactate dehydrogenase, on the electrode surface is used as a proof of concept of the applicability of this new platform for the realization of a biosensor. The possibility of having a single material suitable for antennas, electronics, and now sensing opens new opportunities for smart fabrics in wearable electronic applications
