As crianças e jovens portugueses e a sua perceção da escola em contexto de confinamento social

O presente estudo teve como objetivo analisar o impacto do contexto de confinamento social, causado pela pandemia, nas crianças e jovens portugueses, com idades compreendidas entre os 7 e os 17 anos, ao nível dos seus sentimentos e vivências interpessoais relacionados com a ausência temporária na escola, bem como o enquadramento e relevância das atividades escolares durante a circunstância de confinamento social.Fundos nacionais através da FCT (Fundação para a Ciência e a Tecnologia) no âmbito do projeto do CIEC (Centro de Investigação em Estudos da Criança) da Universidade do Minho, com a referência UIDB/00317/202

Efficacy of pilates in functional body composition : a systematic review

The aim of this review was to collect and systematize results of studies from the last 5 years concerning the influence of the Pilates method (PM) on functional body composition (FBC). Methods: The criteria of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used in this review. We conducted research in three scientific databases: (i) Web of Science Core Collection, (ii) SCOPUS, and (iii) search directory of the library catalog of the Faculty of Sport and Physical Education of the University of Coimbra—EBSCO Discovery Services. We found 334 articles, covering the period between 1 January 2017 and 31 December 2021. After the selection process, we found 33 eligible articles. Results: The main results seem to point to a tendency to get a better body weight and body fat percentage (BFP), hip circumference (HC), waist, and skinfolds from the chest, abdomen, triceps, and supra-iliac in mostly female samples. Available evidence indicates that, in body composition (BC) and FBC, Pilates practice tends to be effective in reducing obesity as a multifactorial condition. Conclusions: It is concluded that there is a marked trend in the benefits of Pilates in FBC, which is in line with other systematic reviews at the BC level (which includes body weight (BW) and body mass index (BMI)) and in the reduction of the percentage of fat mass (FM). It is also concluded that there is a vast lack of studies on the male population, preventing further scientific development in this area. The limitations of this systematic review can be overcome with studies that bring together multidisciplinary aspects of FBC, better designed and methodologically more robust, which will allow more reliable analyses for the implementation of the Pilates method in terms of FBC. In addition, further studies with a male sample or mixed samples (men vs. women) could confirm the trend of no gender differences in the benefits of Pilates practice.info:eu-repo/semantics/publishedVersio

Rapid Communications in Mass Spectrometry published by John Wiley & Sons Ltd.Rationale: 2,4,6-Tris(4-formylphenyl)boroxine (TFPB) is a substituted boroxine containing a benzaldehyde molecule bonded to each boron atom. Boroxine cages are an emerging class of functional nanostructures used in host–guest chemistry, and benzaldehyde is a potential radiosensitizer. Reactions initiated by low-energy electrons with such complexes may dictate and bring new fundamental knowledge for biomedical and pharmaceutical applications. Methods: The electron ionization properties of TFPB are investigated using a gas-phase electron–molecule crossed beam apparatus coupled with a reflectron time-of-flight mass spectrometer in an orthogonal geometry. Ionization and threshold energies are experimentally determined by mass spectra acquisition as a function of the electron energy. Results: The abundance of the molecular precursor cation in the mass spectrum at 70 eV is significantly lower than that of the most abundant fragment C7H5O+. Twenty-nine cationic fragments with relative intensities >2% are detected and identified. The appearance energies of six fragment cations are reported, and the experimental first ionization potential is found at (Formula presented.) eV. Moreover, eight double cations are identified. The present results are supported by quantum chemical calculations based on bound state techniques, electron ionization models and thermodynamic thresholds. Conclusions: According to these results, the TPFB properties may combine the potential radiosensitizer effect of benzaldehyde with the stability of the boroxine ring.publishersversionpublishe

Combining Soft with Hard Condensed Matter for Circular Polarized Light Sensing and Logic Operations

ERC-StG-2014, GA 640598The study shows the incorporation of chiral nematic photonic cellulose nanocrystal (CNC) films, well known for their adaptive character of selective reflection of circular polarized light (CPL), and silicon-based thin-film photodiodes, thus achieving a light sensor capable of discriminating right- from left-handed CPL. The circular polarization (CP) response is maximum for specific wavelengths in the green-to-red region. When subjected to these wavelengths, they produce photocurrents that are over 50% distinct between the two CP states. Proper signal processing, thus, yields a binary output depending on the handedness of the light. Through the addition of monovalent salt to the initial CNC suspension, a blueshift to the photonic band gap is induced, enabling a larger wavelength gamut and application possibilities. The measured results are then used as a basis for electromagnetic simulations that show remarkable consistency with the experimental results, thus defining a new tool that can be used to efficiently optimize the devices’ response. Fast transient responses to CPL are shown with possible logic operations, as well as humidity sensing. The developed devices are, thus, applicable in areas as diverse as imaging, CPL sensing, optoelectronic counterfeiting, and information processing with logic states that depend solely on the handedness of the incident light.publishersversionpublishe

Optoelectronics and Bio Devices on Paper Powered by Solar Cells

The employment of printing techniques as cost-effective methods to fabricate low cost, flexible, disposable and sustainable solar cells is intimately dependent on the substrate properties and the adequate electronic devices to be powered by them. Among such devices, there is currently a growing interest in the development of user-oriented and multipurpose systems for intelligent packaging or on-site medical diagnostics, which would greatly benefit from printable solar cells as their energy source for autonomous operation
