Astrophysics - Solar and Stellar Astrophysics - Abstract
Threads are the building blocks of solar prominences and very often show longitudinal oscillatory motions that are strongly attenuated with time. The damping mechanism responsible for the reported oscillations is not fully understood yet. To understand the oscillations and damping of prominence threads it is mandatory to investigate first the nature of the equilibrium solutions that arise under static conditions and under the presence of radiative losses, thermal conduction and background heating. This provides the basis to calculate the eigenmodes of the thread models. The nonlinear ordinary differential equations for hydrostatic and thermal equilibrium under the presence of gravity are solved using standard numerical techniques and simple analytical expressions are derived under certain approximations. The solutions to the equations represent a prominence thread, i.e., a dense and cold plasma region of a certain length that connects with the corona through a prominence corona transition region (PCTR). The solutions can also match with a chromospheric-like layer if a spatially dependent heating function localised around the footpoints is considered. We have obtained static solutions representing prominence threads and have investigated in detail the dependence of these solutions on the different parameters of the model. Among other results, we have shown that multiple condensations along a magnetic field line are possible, and that the effect of partial ionisation in the model can significantly modify the thermal balance in the thread and therefore their length. This last parameter is also shown to be comparable to that reported in the observations when the radiative losses are reduced for typical thread temperatures., Comment: Accepted for publication in A&A more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Prominence threads are dense and cold structures lying on curved magnetic fields that can be suspended in the solar atmosphere against gravity. The gravitational stability of threads, in the absence of non-ideal effects, is comprehensively investigated in the present work by means of an elementary but effective model. Based on purely hydrodynamic equations in one spatial dimension and applying line-tying conditions at the footpoints of the magnetic field lines, we derive analytical expressions for the different feasible equilibria and the corresponding frequencies of oscillation. We find that the system allows for stable and unstable equilibrium solutions subject to the initial position of the thread, its density contrast and length, and the total length of the magnetic field lines. The transition between the two types of solutions is produced at specific bifurcation points that have been determined analytically in some particular cases. When the thread is initially at the top of the concave magnetic field, that is at the apex, we find a supercritical pitchfork bifurcation, while for a shifted initial thread position with respect to this point the symmetry is broken and the system is characterised by an S-shaped bifurcation. The plain results presented in this paper shed new light on the behaviour of threads in curved magnetic fields under the presence of gravity and help to interpret more complex numerical magnetohydrodynamics (MHD) simulations about similar structures., Comment: 13 pages, 9 figures more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Long-term records of sunspot number and concentrations of cosmogenic radionuclides (10Be and 14C) on the Earth reveal the variation of the Sun's magnetic activity over hundreds and thousands of years. We identify several clear periods in sunspot, 10Be, and 14C data as 1000, 500, 350, 200 and 100 years. We found that the periods of the first five spherical harmonics of the slow magnetic Rossby mode in the presence of a steady toroidal magnetic field of 1200-1300 G in the lower tachocline are in perfect agreement with the time scales of observed variations. The steady toroidal magnetic field can be generated in the lower tachocline either due to the steady dynamo magnetic field for low magnetic diffusivity or due to the action of the latitudinal differential rotation on the weak poloidal primordial magnetic field, which penetrates from the radiative interior. The slow magnetic Rossby waves lead to variations of the steady toroidal magnetic field in the lower tachocline, which modulate the dynamo magnetic field and consequently the solar cycle strength. This result constitutes a key point for long-term prediction of the cycle strength. According to our model, the next deep minimum in solar activity is expected during the first half of this century., Comment: 4 pages, 4 figures, accepted in ApJL more...

- Abstract
Introduction: Gastric cancer continues to be a universal health problem. Their survival rate remains poor despite improvements in diagnosis and treatment. Lymphatic metastases are the most common route of spread of gastric cancer. This lymph node spread being one of the most important prognostic factors. The aim was to assess prognostic capacity based on the survival of the Lymph node ratio (LNR). Methods: A retrospective and single-center observational study on 85 patients who underwent gastric cancer between 2013 and 2021. A descriptive analysis of all study variables was performed and the overall survival rates were compared by the ROC test. Results: The variables that showed a statistically significant relationship with LNR were: lymphadenectomy grade (p = 0.01), radicality (p = 0.01), all TNM categories (pT: p = 0.03; pN: p = < 0.001; pM: p = 0.01) and perineural invasions(p = 0.04), venous invasions (p = 0.01) and lymphovascular invasions(p = < 0.001). A statistically significant relationship (p = 0.039) was found between the LNR and the survival of patients who underwent gastric cancer. All three systems behaved a good predictors. Conclusion: Nodal involvement determined by LNR has been shown as an independent prognostic factor for estimating survival in our cohort, especially in cases with suboptimal lymphadenectomies.

Introduction: Reactive oxygen species (ROS) represent molecules of great interest in the field of regenerative biology since several animal models require their production to promote and favor tissue, organ, and appendage regeneration. Recently, it has been shown that the production of ROS such as hydrogen peroxide (H2O2) is required for tail regeneration in Ambystoma mexicanum. However, to date, it is unknown whether ROS production is necessary for limb regeneration in this animal model. Methods: forelimbs of juvenile animals were amputated proximally and the dynamics of ROS production was determined using 2′7- dichlorofluorescein diacetate (DCFDA) during the regeneration process. Inhibition of ROS production was performed using the NADPH oxidase inhibitor apocynin. Subsequently, a rescue assay was performed using exogenous hydrogen peroxide (H2O2). The effect of these treatments on the size and skeletal structures of the regenerated limb was evaluated by staining with alcian blue and alizarin red, as well as the effect on blastema formation, cell proliferation, immune cell recruitment, and expression of genes related to proximal-distal identity. Results: our results show that inhibition of post-amputation limb ROS production in the A. mexicanum salamander model results in the regeneration of a miniature limb with a significant reduction in the size of skeletal elements such as the ulna, radius, and overall autopod. Additionally, other effects such as decrease in the number of carpals, defective joint morphology, and failure of integrity between the regenerated structure and the remaining tissue were identified. In addition, this treatment affected blastema formation and induced a reduction in the levels of cell proliferation in this structure, as well as a reduction in the number of CD45+ and CD11b + immune system cells. On the other hand, blocking ROS production affected the expression of proximo-distal identity genes such as Aldha1a1, Rarβ, Prod1, Meis1, Hoxa13, and other genes such as Agr2 and Yap1 in early/mid blastema. Of great interest, the failure in blastema formation, skeletal alterations, as well as the expression of the genes evaluated were rescued by the application of exogenous H2O2, suggesting that ROS/H2O2 production is necessary from the early stages for proper regeneration and patterning of the limb. more...

- Abstract
MaxSAT is the problem of finding an assignment satisfying the maximum number of clauses in a CNF formula. We consider a natural generalization of this problem to generic sets of polynomials and propose a weighted version of Polynomial Calculus to address this problem. Weighted Polynomial Calculus is a natural generalization of the systems MaxSAT-Resolution and weighted Resolution. Unlike such systems, weighted Polynomial Calculus manipulates polynomials with coefficients in a finite field and either weights in ℕ or ℤ. We show the soundness and completeness of weighted Polynomial Calculus via an algorithmic procedure. Weighted Polynomial Calculus, with weights in ℕ and coefficients in F2, is able to prove efficiently that Tseitin formulas on a connected graph are minimally unsatisfiable. Using weights in ℤ, it also proves efficiently that the Pigeonhole Principle is minimally unsatisfiable., This work was supported by the grant numbers PID2019-109137GB-C21, PID2019-109137GB-C22, IJC2018-035334-I, PID2022138506NB-C21, and PID2022-138506NB-C22 funded by AEI.

- Abstract
In recent years there has been an increasing interest in studying proof systems stronger than Resolution, with the aim of building more efficient SAT solvers based on them. In defining these proof systems, we try to find a balance between the power of the proof system (the size of the proofs required to refute a formula) and the difficulty of finding the proofs. In this paper we consider the proof systems circular Resolution, Sherali-Adams, Nullstellensatz and Weighted Resolution and we study their relative power from a theoretical perspective. We prove that circular Resolution, Sherali-Adams and Weighted Resolution are polynomially equivalent proof systems. We also prove that Nullstellensatz is polynomially equivalent to a restricted version of Weighted Resolution. The equivalences carry on also for versions of the systems where the coefficients/weights are expressed in unary., This work was supported by the Ministerio de Ciencia e Innovación/Agencia Estatal de Investigación MCIN/AEI/10.13039/501100011033, Spain [grant numbers PID2019-109137GB-C21, PID2019-109137GB-C22, IJC2018-035334-I, PID2022-138506NB-C21], Peer Reviewed, Postprint (published version) more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Alfv\'en waves are a particular class of magnetohydrodynamic waves relevant in many astrophysical and laboratory plasmas. In partially ionized plasmas the dynamics of Alfv\'en waves is affected by the interaction between ionized and neutral species. Here we study Alfv\'en waves in a partially ionized plasma from the theoretical point of view using the two-fluid description. We consider that the plasma is composed of an ion-electron fluid and a neutral fluid, which interact by means of particle collisions. To keep our investigation as general as possible we take the neutral-ion collision frequency and the ionization degree as free parameters. First, we perform a normal mode analysis. We find the modification due to neutral-ion collisions of the wave frequencies and study the temporal and spatial attenuation of the waves. In addition, we discuss the presence of cut-off values of the wavelength that constrain the existence of oscillatory standing waves in weakly ionized plasmas. Later, we go beyond the normal mode approach and solve the initial-value problem in order to study the time-dependent evolution of the wave perturbations in the two fluids. An application to Alfv\'en waves in the low solar atmospheric plasma is performed and the implication of partial ionization for the energy flux is discussed., Comment: Accepted for publication in ApJ more...

Astrophysics - Solar and Stellar Astrophysics ,Physics - Plasma Physics - Abstract
Alfven wave dynamics in partially ionized plasmas of the solar atmosphere shows that there is indeed a cut-off wavenumber, i.e. the Alfven waves with wavenumbers higher than the cut-off value are evanescent. The cut-off wavenumber appears in single-fluid magnetohydrodynamic (MHD) approximation but it is absent in a multi-fluid approach. Up to now, an explanation for the existence of the cut-off wavenumber is still missing. The aim of this paper is to point out the reason for the appearance of a cut-off wavenumber in single-fluid MHD. Beginning with three-fluid equations (with electrons, protons and neutral hydrogen atoms), we performed consecutive approximations until we obtained the usual single-fluid description is obtained. We solved the dispersion relation of linear Alfven waves at each step and sought the approximation responsible of the cut-off wavenumber appearance. We have found that neglecting inertial terms significantly reduces the real part of the Alfven frequency although it never becomes zero. Therefore, the cut-off wavenumber does not exist at this stage. However, when the inertial terms together with the Hall term in the induction equation are neglected, the real part of the Alfven frequency becomes zero. The appearance of a cut-off wavenumber, when Alfven waves in partially ionized regions of the solar atmosphere are studied, is the result of neglecting inertial and Hall terms, therefore it has no physical origin., Comment: 6 pages, 2 figures, accepted in A&A more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Rapidly rotating stars show short-period oscillations in magnetic activity and polar appearance of starspots. The aim of this paper is to study large-scale shallow water waves in the tachoclines of rapidly rotating stars and their connection to the periodicity and the formation of starspots at high latitudes. Shallow-water magnetohydrodynamic equations were used to study the dynamics of large-scale waves at the rapidly rotating stellar tachoclines in the presence of toroidal magnetic field. Dispersion relations and latitudinal distribution of wave modes were derived. We found that low-frequency magnetic Rossby waves tend to be located at poles, but high-frequency magnetic Poincare waves are concentrated near the equator in rapidly rotating stars. These results have important implications for the evolution of the stellar wind in young Sun-like stars. Unstable magnetic Rossby waves may lead to the local enhancement of magnetic flux at high latitudes of tachoclines in rapidly rotating stars. The enhanced magnetic flux may rise upwards owing to the magnetic buoyancy in the form of tubes and appear as starspots at polar regions. Magnetic Rossby waves may also cause observed short-term periodicity in the stellar magnetic activity., Comment: 12 pages, 7 figures, A&A (accepted) more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Quasi-biennial oscillations (QBO) are frequently observed in the solar activity indices. However, no clear physical mechanism for the observed variations has been suggested so far. Here we study the stability of magnetic Rossby waves in the solar tachocline using the shallow water magnetohydrodynamic approximation. Our analysis shows that the combination of typical differential rotation and a toroidal magnetic field with a strength > 10^5 G triggers the instability of the m=1 magnetic Rossby wave harmonic with a period of 2 years. This harmonic is antisymmetric with respect to the equator and its period (and growth rate) depends on the differential rotation parameters and the magnetic field strength. The oscillations may cause a periodic magnetic flux emergence at the solar surface and consequently may lead to the observed QBO in the solar activity features. The period of QBO may change throughout the cycle, and from cycle to cycle, due to variations of the mean magnetic field and differential rotation in the tachocline., Comment: 13 pages, 4 figures, ApJ (in press) more...

Astrophysics - Solar and Stellar Astrophysics - Abstract
Solar prominences are partially ionised plasmas displaying flows and oscillations. These oscillations show time and spatial damping and, commonly, have been explained in terms of magnetohydrodynamic (MHD) waves. We study the spatial damping of linear non-adiabatic MHD waves in a flowing partially ionised plasma, having prominence-like physical properties. We consider single fluid equations for a partially ionised hydrogen plasma including in the energy equation optically thin radiation, thermal conduction by electrons and neutrals, and heating. Keeping the frequency real and fixed, we have solved the obtained dispersion relations for the complex wavenumber, k, and have analysed the behaviour of the damping length, wavelength and the ratio of the damping length to the wavelength, versus period, for Alfven, fast, slow and thermal waves., Comment: 28 pages, 9 figures more...

Apart from the 11-year solar cycle, another periodicity around 155-160 days was discovered during solar cycle 21 in high energy solar flares, and its presence in sunspot areas and strong magnetic flux has been also reported. This periodicity has an elusive and enigmatic character, since it usually appears only near the maxima of solar cycles, and seems to be related with a periodic emergence of strong magnetic flux at the solar surface. Therefore, it is probably connected with the tachocline, a thin layer located near the base of the solar convection zone, where strong dynamo magnetic field is stored. We study the dynamics of Rossby waves in the tachocline in the presence of a toroidal magnetic field and latitudinal differential rotation. Our analysis shows that the magnetic Rossby waves are generally unstable and that the growth rates are sensitive to the magnetic field strength and to the latitudinal differential rotation parameters. Variation of the differential rotation and the magnetic field strength throughout the solar cycle enhance the growth rate of a particular harmonic in the upper part of the tachocline around the maximum of the solar cycle. This harmonic is symmetric with respect to the equator and has a period of 155-160 days. A rapid increase of the wave amplitude could give place to a magnetic flux emergence leading to observed periodicities in solar activity indicators related with magnetic flux., Comment: 34 pages, 5 figures, accepted in ApJ more...

Astrophysics - Abstract
The main aim of this study is to point out the difficulties found when trying to assess the statistical significance of the North-South asymmetry (hereafter SSNSA) of the most usually considered time series of solar activity. First of all, we distinguish between solar activity time series composed by integer or non-integer and dimensionless data, or composed by non-integer and dimensional data. For each of these cases, we discuss the most suitable statistical tests which can be applied and highlight the difficulties to obtain valid information about the statistical significance of solar activity time series. Our results suggest that, apart from the need to apply the suitable statistical tests, other effects such as the data binning, the considered units and the need, in some tests, to consider groups of data, affect substantially the determination of the statistical significance of the asymmetry. Our main conclusion is that the assessment of the statistical significance of the N-S asymmetry of solar activity is a difficult matter and that an absolute answer cannot be given, since many different effects influence the results given by the statistical tests. In summary, the quantitative results about the statistical significance of the N-S asymmetry of solar activity provided by different authors, as well as the studies about its behaviour, must be considered with care because they depend from the chosen values of different parameters or from the considered units., Comment: Astronomy and Astrophysics Latex, 9 pages, 4 figures more...

- Abstract
Parametric design has demonstrated in recent years its ability to revolutionize the construction world, especially in the design phase, where a large number of changes take place. In this context, a Grasshopper script originally developed by Baptiste Woerli, and later continued by Joel Wahlstein and Andreas Granberg, regarding parametric design of pipe bridges in industry, is further developed. Therefore, the Grasshopper plug-in Parametric FEM Toolbox developed by Diego Apellániz is implemented in the script to export all data related to the pipe bridge to RFEM 5, carry out the corresponding finite element calculations there, and import the desired results back to Grasshopper automatically. In addition, a component able to perform the design of single foundations according to Eurocode and the Swedish national annex developed by Sweco, the company with which the thesis is carried out, is combined with the implementation of a multi-objective optimization process using the Wallacei X plug-in to determine the optimal dimensions of the foundations of the structure that minimize cost and CO2 emissions. The results extracted from the RFEM 5 implementation show that the data exchange with Grasshopper is successfully achieved, allowing the correct export of most of the options and alternatives offered by the script, with the exception only of the presence of different pipe bridge sections running in parallel, and the design of structural members, which are expected to be implemented in future studies. In the case of the foundation design optimization, the penalty functions defined and the absence of null values after the optimization process indicate that this implementation works correctly too. Therefore, it can be concluded that the main objectives of this work have been satisfactorily fulfilled, with both implementations being robust. more...

- Abstract
MaxSAT is the problem of finding an assignment satisfying the maximum number of clauses in a CNF formula. We consider a natural generalization of this problem to generic sets of polynomials and propose a weighted version of Polynomial Calculus to address this problem. Weighted Polynomial Calculus is a natural generalization of MaxSAT-Resolution and weighted Resolution that manipulates polynomials with coefficients in a finite field and either weights in N or Z. We show the soundness and completeness of these systems via an algorithmic procedure. Weighted Polynomial Calculus, with weights in N and coefficients in F2, is able to prove efficiently that Tseitin formulas on a connected graph are minimally unsatisfiable. Using weights in Z, it also proves efficiently that the Pigeonhole Principle is minimally unsatisfiable., This work was supported by the Spanish Agencia Estatal de Investigación with the grant PID2019-109137GB-C21/AEI/10.13039/501100011033 and the grant PID2019-109137GBC22/AEI/10.13039/501100011033.

- Abstract
The discovery and improvements of antimicrobial peptides (AMPs) have become an alternative to conventional antibiotics. They are usually small and heat-stable peptides, exhibiting inhibitory activity against Gram-negative and Gram-positive bacteria. In this way, studies on broad-spectrum AMPs found in amphibians with the remarkable capability to regenerate a wide array of tissues are of particular interest in the search for new strategies to treat multidrug-resistant bacterial strains. In this work, the use of bioinformatic approaches such as sequence alignment with Fasta36 and prediction of antimicrobial activity allowed the identification of the Ramosin peptide from the de novo assembled transcriptome of the plethodontid salamander Bolitoglossa ramosi obtained from post-amputation of the upper limb tissue, heart, and intestine samples. BLAST analysis revealed that the Ramosin peptide sequence is unique in Bolitoglossa ramosi. The peptide was chemically synthesized, and physicochemical properties were characterized. Furthermore, the in vitro antimicrobial activity against relevant Gram-positive and Gram-negative human pathogenic bacteria was demonstrated. Finally, no effect against eukaryotic cells or human red blood cells was evidenced. This is the first antibacterial peptide identified from a Colombian endemic salamander with interesting antimicrobial properties and no hemolytic activity. more...

Entre el 15 y el 17 de noviembre Barcelona acogerá el V Congreso Nacional de Farmacéuticos Comunitarios, organizado por SEFAC y que ha sido reconocido de interés sanitario por el Ministerio de Sanidad, Servicios Sociales e Igualdad. La edición de este año tiene como lema Soluciones para una farmacia necesaria, efectiva y segura y no puede ser más oportuna esta idea en el contexto actual en el que se desenvuelve la profesión. Desde hace años vivimos tiempos de incertidumbre y dificultades, jalonados por continuas rebajas en los precios de los medicamentos y agravados por la actual coyuntura económica, lo que se ha traducido en la puesta en marcha de medidas improvisadas, que están generando mucha incertidumbre en un sector que necesita estabilidad. Últimamente estamos sufriendo el establecimiento de nuevos copagos, la desfinanciación de medicamentos, los cambios periódicos en los precios menores y numerosos impagos que arriesgan la viabilidad de muchas farmacias. El Congreso de noviembre quiere ser el punto de encuentro ideal y un punto de inflexión para que los farmacéuticos comunitarios de toda España compartamos nuestras inquietudes y experiencias en la búsqueda de propuestas que nos permitan encarar el futuro con optimismo. Somos conscientes de que en estos momentos el desánimo abunda entre muchos compañeros farmacéuticos, pero no debemos dejar que ese sentimiento nos arrastre, pues son muchas las actividades que el farmacéutico lleva a cabo en la farmacia comunitaria por la sociedad, los pacientes, la sostenibilidad del sistema sanitario y, en definitiva, por sí misma. Debemos ser capaces de transmitir esto y darle visibilidad y, para ello, es imprescindible que no bajemos los brazos y trabajemos desde la unión y el compromiso en defensa de los valores que aporta la farmacia asistencial y el farmacéutico como verdadero experto en medicamentos. more...

EngiMath is a 3 ECTS online course in engineering mathematics, in seven different languages, and it is the main and practical output of the ERASMUS+ project entitled “Mathematics online learning model in engineering education” in which the authors were participating. The course is integrated with Learning Management Systems such as Moodle and it is compatible with other platforms using Learning Tools Interoperability. Once the project is finished, authors undertake, with the support of the Institute of Education Sciences at the Universitat Politècnica de Catalunya-BarcelonaTECH (UPC), an innovation project, EngiMath@UPC, with three practical objectives: a) to incorporate EngiMath into the teaching activity of the widest as possible range of students at UPC, b) to gather students and faculty feedback regarding the tracking of materials and their performance in the student training process, and c) to statistically analyze the data collected in order to validate and adjust the follow-up of the materials. In connection with the above mentioned objective b) a training course addressed to the math professors has been prepared at UPC. The paper introduces, on the one hand, the EngiMath course as an online open educational resource for the academic community benefit, and on the other hand, analyzes the valuable feedback given by the training activity participants. Details on the online course implementation as well as main conclusions will be presented and discussed throughout the document. more...

Aquest article descriu els resultats del projecte “de las MATES al STEAM”, el qual es va completar durant els anys 2019 a 2021 a la E.T.S. d’Enginyeria de Camins, Canals i Ports. L'objectiu inicial del projecte era desenvolupar i aplicar una sèrie d’activitats per la infusió de continguts de Construcció 4.0 a un grau en Enginyeria Civil. Fent èmfasi en els estudiants de primers cursos i amb una perspectiva d’inclusió, l’acrònim desconstruït MATES-STEAM va donar peu al projecte. Tot i que el desenvolupament del projecte ha coincidit amb les restriccions sanitàries global i no es van poder desenvolupar activitats presencials, es presenten una sèrie de resultats obtinguts. La sèrie d’activitats desenvolupada mostren una perspectiva triple: i) totes estan relacionades amb la construcció 4.0, ii) totes tenen una visió STEAM by-design i iii) totes es conceben amb maquinari i programari de codi obert, accessible i assequible. Projectes inicials i finals (cornerstone i capstone), així com un conjunt de tallers, representen alguns demostradors d'aquestes activitats. En els propers anys, s'espera que un desplegament més sistemàtic millorat d'aquestes activitats permeti avaluar l'evolució entre eines, pedagogies STEAM i les necessitats del sector de la Construcció. more...

- Abstract
BACKGROUND: Information on tuberculosis (TB) and coronavirus disease 2019 (COVID-19) is still limited. The aim of this study was to describe the features of the TB/COVID-19 co-infected individuals from a prospective, anonymised, multicountry register-based cohort with special focus on the determinants of mortality and other outcomes. METHODS: We enrolled all patients of any age with either active TB or previous TB and COVID-19. 172 centres from 34 countries provided individual data on 767 TB-COVID-19 co-infected patients, (>50% population-based). RESULTS: Of 767 patients, 553 (74.0%) out of 747 had TB before COVID-19 (including 234 out of 747 with previous TB), 71 (9.5%) out of 747 had COVID-19 first and 123 (16.5%) out of 747 had both diseases diagnosed within the same week (n=35 (4.6%) on the same day). 85 (11.08%) out of 767 patients died (41 (14.2%) out of 289 in Europe and 44 (9.2%) out of 478 outside Europe; p=0.03): 42 (49.4%) from COVID-19, 31 (36.5%) from COVID-19 and TB, one (1.2%) from TB and 11 from other causes. In the univariate analysis on mortality the following variables reached statistical significance: age, male gender, having more than one comorbidity, diabetes mellitus, cardiovascular disease, chronic respiratory disease, chronic renal disease, presence of key symptoms, invasive ventilation and hospitalisation due to COVID-19. The final multivariable logistic regression model included age, male gender and invasive ventilation as independent contributors to mortality. CONCLUSION: The data suggest that TB and COVID-19 are a "cursed duet" and need immediate attention. TB should be considered a risk factor for severe COVID disease and patients with TB should be prioritised for COVID-19 preventative efforts, including vaccination. more...

- Abstract
According to the New UNESCO global survey studying the effect of Covid-19 on higher education (2021) the pandemic has had an impact on higher education systems in terms of access and quality of teaching and learning. Covid-19 has caused the suspension and cancellation of teaching activities and its major impact on teaching and learning is the increase in online education. The Engimath - Mathematics on-line learning model in engineering education - was successfully carried out at the very right moment, as in recent two years there has been a significant increase in demand for a 100% online mathematics course with interactive learning materials and largescale practicing opportunities as well as for a mathematics online assessment model. This project has successfully developed a high-level online course as a basis for offering output-oriented education in engineering mathematics. Some of development stages, that led this project – EngiMath - to an outstanding successful end, will be presented in this paper. These go from the educational needs’ analysis to its implementation and use, even allowing an open and live test., Peer Reviewed, Objectius de Desenvolupament Sostenible::4 - Educació de Qualitat, Objectius de Desenvolupament Sostenible::4 - Educació de Qualitat::4.3 - Per a 2030, assegurar l’accés en condicions d’igualtat per a tots els homes i dones a una formació tècnica, professional i superior de qualitat, inclòs l’ensenyament universitari, Objectius de Desenvolupament Sostenible::4 - Educació de Qualitat::4.4 - Per a 2030, augmentar substancialment el nombre de joves i persones adultes que tenen les competències necessàries, en particular tècniques i professionals, per a accedir a l’ocupació, el treball digne i l’emprenedoria, Postprint (published version) more...

- Abstract
EngiMath is a 3 ECTS online course in engineering mathematics, in seven different languages, and it is the main and practical output of the ERASMUS+ project entitled “Mathematics online learning model in engineering education” in which the authors were participating. The course is integrated with Learning Management Systems such as Moodle and it is compatible with other platforms using Learning Tools Interoperability. Once the project is finished, authors undertake, with the support of the Institute of Education Sciences at the Universitat Politècnica de Catalunya-BarcelonaTECH (UPC), an innovation project, EngiMath@UPC, with three practical objectives: a) to incorporate EngiMath into the teaching activity of the widest as possible range of students at UPC, b) to gather students and faculty feedback regarding the tracking of materials and their performance in the student training process, and c) to statistically analyze the data collected in order to validate and adjust the follow-up of the materials. In connection with the above mentioned objective b) a training course addressed to the math professors has been prepared at UPC. The paper introduces, on the one hand, the EngiMath course as an online open educational resource for the academic community benefit, and on the other hand, analyzes the valuable feedback given by the training activity participants. Details on the online course implementation as well as main conclusions will be presented and discussed throughout the document. more...

- Abstract
Desarrollar la educaci��n alimentaria y nutricional es un proceso que requiere el concurso de todos los que de una u otra manera incidimos en la educaci��n de las nuevas generaciones, este trabajo obedece a la necesidad de fortalecer esta concepci��n en los estudiantes. El objetivo fue exponer las experiencias de la asignatura Toxicolog��a de los Alimentos en la educaci��n alimentaria y nutricional de los estudiantes de tercer a��o de la carrera de Ciencias Alimentarias en Facultad de Ciencias Aplicadas. La muestra qued�� conformada por los 34 estudiantes de tercer a��o de la carrera, los que participaron en los seminarios, videos y talleres realizados. Se aplic�� una encuesta en dos momentos, en la que se pudo comprobar que la educaci��n alimentaria y nutricional es una tem��tica conocida por los estudiantes de la carrera, pero no en toda su dimensi��n. Se concluye que la experiencia pedag��gica permiti�� mejorar la integraci��n de los conocimientos de la asignatura con los de la educaci��n alimentaria y nutricional y fue aplicada a situaciones que se pueden encontrar durante el desempe��o profesional de estos, lo que permite ampliar sus argumentos, durante las tareas de informaci��n cient��fico t��cnica y comercializaci��n, relacionadas con su esfera de actuaci��n. Palabras claves: educaci��n alimentaria y nutricional, h��bitos nutricionales, dieta. more...
