App Grow Green: un instrumento para la innovación docente en la formación ambiental

[ES] Hoy en día, resulta imposible enseñar y educar como antaño a una nueva generación de estudiantes que vive conectada a la tecnología. Una visión moderna del aprendizaje requiere la adaptación de estrategias y métodos clásicos de enseñanza. Este estudio propone la introducción de una aplicación móvil lúdica como recurso tecnológico de apoyo al aprendizaje, que fomente la educación y la conciencia ambiental en los estudiantes del Campus de Vera de la Universitat Politècnica de València. La aplicación Grow Green es una herramienta innovadora, que tiene el potencial de conseguir objetivos educativos y de sostenibilidad, más allá del mero entretenimiento. Este proyecto de gamificación desea ayudar a los estudiantes a conocer elementos de la biodiversidad local mediante diferentes rutas de flora (árboles y arbustos) y fauna (aves) urbana, experimentar la movilidad sostenible, disfrutar de los beneficios suministrados por elementos de infraestructura verde y descubrir estrategias verdes para la resiliencia urbana. El compromiso ambiental es otro contexto prometedor para la gamificación, facilitando la participación de la comunidad universitaria en censos de aves. La implantación de la aplicación Grow Green fomentará la adquisición de competencias específicas y transversales, que proporcionan un valor añadido a los estudiantes y otorgan un mayor atractivo al currículo docente.[EN] Nowadays, it is impossible to teach and educate a new generation of students who lives connected to technology in the same way it was done before.

Raman and infrared spectra of dimethyl ether 13C-isotopologue (CH3O13CH3) from a CCSD(T) potential energy surface

So far, no experimental data of the infrared and Raman spectra of 13C isotopologue of dimethyl ether are available. With the aim of providing some clues of its low-lying vibrational bands and with the hope of contributing in a next spectral analysis, a number of vibrational transition frequencies below 300 cm−1 of the infrared spectrum and around 400 cm−1 of the Raman spectrum have been predicted and their assignments were proposed. Calculations were carried out through an ab initio three dimensional potential energy surface based on a previously reported one for the most abundant dimethyl ether isotopologue (M. Villa et al., J. Phys. Chem. A 115 (2011) 13573). The potential function was vibrationally corrected and computed with a highly correlated CCSD(T) method involving the COC bending angle and the two large amplitude CH3 internal rotation degrees of freedom. Also, the Hamiltonian parameters could represent a support for the spectral characterization of this species. Although the computed vibrational term values are expected to be very accurate, an empirical adjustment of the Hamiltonian has been performed with the purpose of anticipating some workable corrections to any possible divergence of the vibrational frequencies. Also, the symmetry breaking derived from the isotopic substitution of 13C in the dimethyl ether was taken into account when the symmetrization procedure was applied

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.814.4 million) incident T2D cases, representing 70.3% (68.871.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.027.1%)), excess refined rice and wheat intake (24.6% (22.327.2%)) and excess processed meat intake (20.3% (18.323.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.487.7%)) and Latin America and the Caribbean (81.8% (80.183.4%)); and lowest proportional burdens were in South Asia (55.4% (52.160.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally. (c) 2023, The Author(s)

Children's and adolescents' rising animal-source food intakes in 1990-2018 were impacted by age, region, parental education and urbanicity

Animal-source foods (ASF) provide nutrition for children and adolescents physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the worlds child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 1519 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes. (c) 2023, The Author(s)

They are used simultaneously with a previous spectrum of the $\nu_{12}$ band, also recorded in Brussels, to perform the analysis of the $\nu_{10}/\nu_7/\nu_4/\nu_{12}$ region, lying from 600 cm$^{-1}$ to $1500$ cm$^{-1}$. Following our work devoted to the $\nu_{12}$ band considered as isolated, we performed a frequency re-analysis of the $\nu_{10}/\nu_7/\nu_4/\nu_{12}$ infrared tetrad in the $600 - 1500$ cm$^{-1}$ region, thanks to the tensorial formalism developed in Dijon for X$_2$Y$_4$ asymmetric-top molecules, {\bf 217} 239--248 (2003).} and the XTDS software package, {\bf 251} 102--113 (2008). }. Including the strong Coriolis interaction affecting the upper vibrational levels $10^1$, $7^1$, $4^1$ and $12^1$, a total of $11727$ lines have been assigned and fitted as a tetrad with a global root mean square deviation of $0.338 \times 10^{-3}$ cm$^{-1}$

Coupled large amplitude motions: a case study of the dimethylbenzaldehyde isomers.

International audienceThe microwave spectra of the 3,4- (syn and anti), 2,5- (syn), and 3,5-dimethylbenzaldehyde (DMBA) molecules have been recorded for the first time in the 2-26.5 GHz frequency range, using the high resolution COBRA-FTMW spectrometer in Hannover. The experimental assignments and fits are supplemented by ab initio quantum chemical calculations of the conformational energy landscape and dipole moment components. The analysis of the spectra of the four observed isomers, including spectroscopic constants and large amplitude motion parameters, are presented in this paper. The DMBA isomers belong to a series of similar molecules obtained formally by adding one or more methyl group(s) at the aromatic ring. These molecules serve as prototype systems for the development of the theoretical model of asymmetric top molecules having C(s) symmetry while containing in addition two nonequivalent methyl tops (C(3v)), exhibiting different barrier heights and coupling terms. Thus, the DMBA isomers represent good species for testing the recently written two-top internal rotors BELGI program
