The Gaia-ESO Survey: Structural and dynamical properties of the young cluster Chamaeleon i
2017
Investigating the physical mechanisms driving the dynamical evolution of young star clusters is fundamental to our understanding of the star formation process and the properties of the Galactic field stars. The young (~2 Myr) and partially embedded cluster Chamaeleon I is one of the closest laboratories for the study of the early stages of star cluster dynamics in a low-density environment. The aim of this work is to study the structural and kinematical properties of this cluster combining parameters from the high-resolution spectroscopic observations of the Gaia-ESO Survey with data from the literature. Our main result is the evidence of a large discrepancy between the velocity dispersion …
Search for cosmic sources in neutrino telescopes and time calibration in the ANTARES neutrino telescope
2018
Aunque la astronomía de neutrinos es una disciplina muy reciente, está resultando ser muy en un estado estimulante. Los diversos resultados publicados por la colaboración IceCube han mostrado la existencia de un flujo de neutrinos cósmicos de altas energías, del cual se desconoce su origen, y del que no se ha observado una dirección privilegiada. El telescopio de neutrinos ANTARES ha sido capaz de excluir la posibilidad de que algunos de los eventos observados por IceCube se hayan producido por una fuente puntual en la región del centro galáctico. Además, el último análisis de flujos difusos de ANTARES muestra un resultado compatible con el flujo observado por IceCube. Actualmente, existen …

Restoring Harmony in the Lifeworld? : Identity, Learning, and Leaving Preelite Sport
2020
Sport provides many youth participants with a central life project, and yet very few eventually fulfill their athletic dreams, which may lead them to disengage from sport entirely. Many studies have explored the processes of athletic retirement, but little is known about how youth athletes actually reconstruct their relationship with sport and embodiment postretirement. The authors explored these issues in the story of “Pilvi,” a Finnish alpine skier who disengaged from sport in her late adolescence. Employing an existential-phenomenological approach, they conducted six low-structured interviews with Pilvi, combined with visual methods, and identified key themes relating to the body, space,…
A study of the atmospherically important reactions between dimethyl selenide (DMSe) and molecular halogens (X2 = Cl2, Br2, and I2) with ab initio cal…
2012
The atmospherically relevant reactions between dimethyl selenide (DMSe) and the molecular halogens (X(2) = Cl(2), Br(2), and I(2)) have been studied with ab initio calculations at the MP2/aug-cc-pVDZ level of theory. Geometry optimization calculations showed that the reactions proceed from the reagents to the products (CH(3)SeCH(2)X + HX) via three minima, a van der Waals adduct (DMSe:X(2)), a covalently bound intermediate (DMSeX(2)), and a product-like complex (CH(3)SeCH(2)X:HX). The computed potential energy surfaces are used to predict what molecular species are likely to be observed in spectroscopic experiments such as gas-phase photoelectron spectroscopy and infrared matrix isolation s…

Comparing tacrolimus ointment and oral cyclosporine in adult patients affected by atopic dermatitis: a randomized study
2004
BACKGROUND: Atopic dermatitis (AD) is a chronic allergic inflammatory disease, which manifests itself with eczematous skin lesions. OBJECTIVE: We compared the clinical efficacy of tacrolimus ointment (0.1%) given twice a day and oral cyclosporine (3 mg/kg) given once daily. Rescue medication for itching included cetirizine 10-20 mg (equal to one or two tables). METHODS: Thirty patients, aged 13-45 years (mean+/-SD 27.1+/-10.9), with a history of moderate-to-severe AD were randomized to treatments, 15 patients for each treatments. Assessment of efficacy was based on SCORAD, on scores of daily itching, erythema, interference with sleep, due to the skin condition and days without use of cetiri…
Inversion of Left Atrial Appendage Will Cause Compressive Stresses in the Tissue: Simulation Study of Potential Therapy
2022
In atrial fibrillation (AF), thromboembolic events can result from the particular conformation of the left atrial appendage (LAA) bearing increased clot formation and accumulation. Current therapies to reduce the risk of adverse events rely on surgical exclusion or percutaneous occlusion, each of which has drawbacks limiting application and efficacy. We sought to quantify the hemodynamic and structural loads of a novel potential procedure to partially invert the “dead” LAA space to eliminate the auricle apex where clots develop. A realistic left atrial geometry was first achieved from the heart anatomy of the Living Heart Human Model (LHHM) and then the left atrial appendage inversion (LAAI…
Jak doskonalić szkolne projekty edukacyjne - od empirii do praktyki
2018
Celem artykułu jest prezentacja badań własnych dotyczących wybranych aspektów realizacji projektów. Autorka, odwołując się do historycznych korzeni metody projektów, przedstawia jej główne cechy, następnie wyniki badań przeprowadzonych na grupie uczniów szkoły średniej. Przedstawiona w tekście analiza odnosi się do takich cech metody projektów, jak interdyscyplinarność, autonomia uczniów oraz procesowość pracy projektowej. Autorka zwraca uwagę zarówno na symptomy negatywne związane z doświadczeniami młodzieży i realizowanymi projektami (np. ograniczony wymiar interdyscyplinarnego podejścia czy procesowości pracy projektowej), jak i pozytywne, odnoszące się do roli nauczycieli jako osób pomo…
