Portuguese Adaptation of Students Engagement in Schools International Scale (SE...

The importance of student’s engagement has been recently pointed out in research. However, there has been a lack of engagement assessment instrument, pertaining psychometric qualities. Objective: This paper presents the Portuguese adaptation of the “Student’s Engagement in School International Scale” (SESIS), drawn up from a12 countries international study (Lam et al., 2012; Lam et al., in press). Method: Psych...

Emociones y salud actividades propiciadoras de emociones positivas

Se parte del concepto de emoción positiva, vivida en contextos, cuya experiencia subjetiva, es auto-percibida como bienestar (Seligman & Csikszentmihalyi, 2000), razón por la que se considera aquí como promotora de Salud. Así, este estudio de carácter cualitativo organiza, con una “teoría basada en los datos”, las entrevistas semi-estructuradas, en una muestra intencional de 60 profesores. Los contenidos discur...

Bragg Gratings with Enhanced Temperature Sustainability Written in a High- Germ...

In this contribution we report the achievement offiber Bragg gratings exhibiting high temperaturesustainability, resultant from type IIA and a new abnormalexposition regimes, and compare their thermal stability withother gratings obtained from different growth mechanisms,namely type I and IA. It is expected that type IIA and thedesignated as abnormal gratings improve the reliability ofhigh-temperature grating-s...

Dispersion modeling a dynamic chromatic dispersion compensator based on Bragg g...

We report a method to realize tunable chromatic dispersion compensation based on chirped fiber Bragg gratings (CFBG). The changes on the CFBG dispersion are achieved by controlling a temperature gradient applied to the grating. A thermodynamic model is presented enabling us to simulate the temperature distribution along the grating lenght. Furthermore, a theoretical approach was de...

Phenolic composition and antioxidant activity of Rocha pear and other pear cult...

The phenolic profile and the antioxidant activity of Rocha pear, a Portuguese pear cultivar, were determined and compared with the commercially available pear varieties Cornice, Abate, General Leclerc and Passe Crassane. Phenolic composition of the methanolic extracts of these pears was determined by high performance liquid chromatography with diode array detection (HPLC-DAD), while antioxidant activities were ...

Phytochemical profile and anticholinesterase and antimicobial activities of sup...

Winter savory Satureja montana is a medicinal herb used in traditional gastronomy for seasoning meats and salads. This study reports a comparison between conventional (hydrodistillation, HID, and Soxhlet extraction, SE) and alternative (supercritical fluid extraction, SFE) extraction methods to assess the best option to obtain bioactive compounds. Two different types of extracts were tested, the volatile (SFE-9...
