Moodle Reaction Question Generator
(2026) Fernández Marcos, Carlos; Martínez-Caballero, Sonia; Universidad de Extremadura. Departamento de Química Orgánica e Inorgánica; Universidad de Extremadura. Departamento de Didáctica de las Ciencias Experimentales y Matemáticas
This is a Streamlit application designed to generate Moodle-compatible questions for chemical reactions, including embedded images of the reactions. Users can input reactants and products as SMILES strings, select a missing molecule, and generate an XML file for Moodle's question bank. Additionally, it supports searching for canonical SMILES by molecule name using the NCI CIR API and bulk uploading questions via Excel/CSV files.
Moodle Chemistry Question Generator
(2026) Fernández Marcos, Carlos; Martínez-Caballero, Sonia; Universidad de Extremadura. Departamento de Química Orgánica e Inorgánica; Universidad de Extremadura. Departamento de Didáctica de las Ciencias Experimentales y Matemáticas
This Streamlit application is designed to streamline the process of creating Moodle quiz questions of the pmatchjme type. These questions require students to draw a chemical structure using the integrated JSME molecular editor. The application automatically handles the heavy lifting: looking up the canonical SMILES for common compounds via the NCI Chemical Identifier Resolver (CIR) API and standardizing the structure using a hidden JSME component before exporting the final Moodle XML file.
La perspectiva persa y la griega en "Persas" de Esquilo y su función dramática
(Universidade de Coimbra, 2024) Librán Moreno, Míriam; Universidad de Extremadura. Departamento de Ciencias de la Antigüedad
El presente trabajo estudia la imagen de los persas en Persas de Esquilo y propone que Esquilo superpone voluntariamente la perspectiva griega y la persa, en varios casos eco de la propaganda aqueménida, para lograr sus propósitos dramáticos.
Non-Newtonian rheology in inertial suspensions of inelastic rough hard spheres under simple shear flow

Non-Newtonian transport properties of an inertial suspension of inelastic rough hard spheres under simple shear flow are determined by the Boltzmann kinetic equation. The influence of the interstitial gas on rough hard spheres is modeled via a Fokker–Planck generalized equation for rotating spheres accounting for the coupling of both the translational and rotational degrees of freedom of grains with the background viscous gas. The generalized Fokker–Planck term is the sum of two ordinary Fokker–Planck differential operators in linear v and angular ω velocity space. As usual, each Fokker–Planck operator is constituted by a drag force term (proportional to v and/or ω) plus a stochastic Langevin term defined in terms of the background temperature Tex. The Boltzmann equation is solved by two different but complementary approaches: (i) by means of Grad’s moment method and (ii) by using a Bhatnagar–Gross–Krook (BGK)-type kinetic model adapted to inelastic rough hard spheres. As in the case of smooth inelastic hard spheres, our results show that both the temperature and the non-Newtonian viscosity increase drastically with an increase in the shear rate (discontinuous shear thickening effect) while the fourth-degree velocity moments also exhibit an S-shape. In particular, while high levels of roughness may slightly attenuate the jump of the viscosity in comparison to the smooth case, the opposite happens for the rotational temperature. As an application of these results, a linear stability analysis of the steady simple shear flow solution is also carried out showing that there are regions of the parameter space where the steady solution becomes linearly unstable. The present work extends previous theoretical results (H. Hayakawa and S. Takada, “Kinetic theory of discontinuous rheological phase transition for a dilute inertial suspension,” Prog. Theor. Exp. Phys. 2019, 083J01 and R. G. González and V. Garzó, “Simple shear flow in granular suspensions: Inelastic Maxwell models and BGK-type kinetic model,” J. Stat. Mech. 2019, 013206) to rough spheres.
Prevalence and persistence of post-COVID-19 condition after critical care: 32-month follow-up
(MDPI, 2026) Ávila Nieto, Alicia; Infante, Paulo; Barca Durán, Francisco Javier; Universidad de Valaldolid; Universidade de Évora. Portugal; Universidad de Extremadura. Departamento de Enfermería
Background/Objectives: Post-COVID-19 condition (PCC) remains poorly characterized beyond two years, particularly among intensive care unit (ICU) survivors. We aimed to describe the prevalence, persistence, and late consequences of PCC up to 32 months after discharge in an ICU cohort. Methods: This single-center longitudinal cohort included 170 adults with confirmed SARS-CoV-2 infection admitted to an ICU in Cáceres (Spain) between March 2020 and March 2021. 94 survivors entered follow-up at discharge and 3, 6, 12, 18, 24, and 32 months. PCC manifestations were grouped into five organ system domains (respiratory, cardiovascular, renal, infectious, and musculoskeletal/neuromuscular) and recorded only when supported by clinician-confirmed diagnoses or diagnostic tests. Prevalence at each visit, persistence, and new onset of manifestations between 3 and 6 months, and the cumulative incidence of new chronic diseases between 18 and 32 months were estimated with 95% confidence intervals. Results: Any PCC manifestation was almost universal at discharge (96.8% [95% CI, 91.1–98.9]) and remained high at 12 months (85.2% [95% CI, 76.3–91.2]), declining to 48.6% at 24 months and 25.7% at 32 months. Respiratory manifestations predominated early and were largely resolved by 32 months, whereas musculoskeletal/neuromuscular involvement remained relatively stable. From 18 to 32 months, 36.5% (95% CI, 26.4–47.9) of survivors developed at least one chronic condition, most frequently cardiovascular disease (14.9% [95% CI, 8.5–24.7]). Conclusions: Long-term PCC manifestations and incident chronic diseases are common among ICU COVID-19 survivors, underscoring the need for prolonged follow-up and post-ICU care.
