Suppressing chaos in damped driven systems by non-harmonic excitations: experimental robustness against potential’s mismatches

The robustness of a chaos-suppressing scenario against potential mismatches is experimentally studied through the universal model of a damped, harmonically driven two-well Duffing oscillator subject to non-harmonic chaos-suppressing excitations. We consider a second order analogous electrical circuit having an extremely simple two-well potential that differs from that of the standard two-well Duffing model, and compare the main theoretical predictions regarding the chaos-suppressing scenario from the latter with experimental results from the former. Our experimental results prove the high robustness of the chaos-suppressing scenario against potential mismatches regardless of the (constant) values of the remaining parameters. Specifically, the predictions of an inverse dependence of the regularization area in the control parameter plane on the impulse of the chaos-suppressing excitation as well as of a minimal effective amplitude of the chaos-suppressing excitation when the impulse transmitted is maximum were experimentally confirmed.Ministerio de Ciencia, Innovación y Universidades (MICIU, Spain) and FEDER funds Project No. PID2019-108508GB-100/AEI/10.13039/501100011033Junta de Extremadura (JEx, Spain) and FEDER funds Project No. GR1808

Bowel obstruction in adults due to ascariasis

In the world the most frequent and cosmopolitan parasitosis of all human helminthiasis is that caused by ascaris lumbricoides this sickness affects 1.5 billion people around the world, and approximately 60,000 people die annually as the result, about of complications, the intestinal obstruction being the most frequent complication from 38 to 87.5%, the humans become infected by ingesting the larvated eggs of the parasite. OPS report a prevalence of 46 million children between 1-year-old and 14 years old, the most importance prevalence occurs in children between 2 years old and 10 years old, decreasing significantly from the 15 years old. Mexico report through SINAVE (SEMARNAT 2020) a national incidence of 24,203 cases, the State of Sinaloa a total of 690 cases (2.8%). Lack of sanitation, drinking water and precariousness are risk factors for complications such as obstruction a complication that can progress to death

Evaluation of the rights and obligations of the teachers and the education community by families

El presente trabajo tiene como objetivo principal conocer el grado de aceptación que tienen los deberes y derechos docentes y de la comunidad educativa entre las madres y padres que tienen hijos escolarizados en institutos y colegios. Se trata de una investigación descriptiva. Como instrumento de evaluación se ha empleado el cuestionario “Deberes y derechos del profesorado en la comunidad educativa”. En los resultados se demuestra que las madres y los padres consideran muy importantes los deberes y derechos presentados, sin que se observen diferencias significativas en función de la titularidad de los centros educativos, el cargo que ostentan en la asociación, la edad o el género de los participantes.The main objective of this study was to determine the extent to which the rights and obligations of teachers and the educational community are accepted by the parents of children enrolled in primary and high schools. This was a descriptive study. The questionnaire “Duties and obligations of teachers in the educational community” was used as the assessment instrument. The results show that parents considered the rights and obligations presented to be of great importance, with no significant differences observed in terms of ownership of schools, the post parents held in the association, or the age or sex of the participants

Perceptions of families and Primary and Secondary Education teachers concerning teachers’ rights and obligations: opportunities for collaboration

Los autores realizan una investigación descriptiva para comprobar si existen diferencias significativas en las percepciones que madres, padres y profesorado tienen de los deberes y derechos docentes y las posibilidades de colaboración. En la recolección de datos se utiliza el cuestionario “Deberes y derechos del profesorado en la comunidad educativa”. Participan 394 docentes y 348 madres y padres de alumnos de toda España. Los resultados corroboran la hipótesis en Educación Primaria pero no en Secundaria, donde se deben introducir cambios sustanciales para que los institutos puedan beneficiarse de la colaboración de madres y padres. Se concluye que los deberes y derechos docentes pueden servir para promover la colaboración entre la escuela y las familias y ayudar a conseguir el equilibrio entre el derecho de los padres a participar y la autonomía de los docentes como profesionales.We conducted a descriptive study to determine whether there are significant differences in the perceptions that mothers, fathers and teachers have of teachers’ rights and obligations and of the possibilities for collaboration. To collect the data, we used a questionnaire entitled "Rights and obligations of teachers in the educational community" (Larrosa, 2009). 394 teachers and 348 parents of students throughout Spain participated. The results support the hypothesis in Primary but not in Secondary Education, where substantial changes would be required in order for schools to benefit from parental collaboration. We conclude that teachers’ rights and obligations could serve to promote collaboration between schools and families and to help achieve a balance between the rights of parents to participate and teachers’ professional autonomy

The Therapeutic and Educational Unit at Villabona prison, a new penal model of social rehabilitation

La societat estructura les relacions socials a través del risc. La por de la possible pèrdua dels nostres béns socials protegits ens ha portat a un canvi de paradigma en la intervenció penal. Passem de models de responsabilitat a models de seguretat ciutadana i a la identificació del delinqüent com a enemic social. Tanmateix, la gestió eficient del risc per part de l’administració penitenciària passa per possibilitar processos de reeducació i reinserció efectius. La Unitat Terapèutica i Educativa del Centre Penitenciari de Villabona s’ha erigit com un dels models penals que permeten aconseguir els ideals constitucionals. La seva tasca de reeducació efectiva i el disseny de propostes de reinserció, tenint com a eix de l’acció el mateix intern en tant que subjecte actiu del seu procés resocialitzador, asseguren un model penal que redueix la taxa de reincidència i construeix una societat més cohesionada i participativa.Nuestra sociedad estructura las relaciones sociales a través del riesgo. El miedo a la posible pérdida de nuestros bienes sociales protegidos nos ha llevado a un cambio en el paradigma de la intervención penal.

Sin embargo, la gestión eficiente del riesgo por parte de la administración penitenciaria pasa por posibilitar procesos de reeducación y reinserción efectivos. La Unidad Terapéutica y Educativa del Centro Penitenciario de Villabona se ha erigido como uno de los modelos penales que permiten conseguir los ideales constitucionales. Su trabajo de reeducación efectiva y el diseño de propuestas de reinserción, teniendo como eje de la acción al propio interno como sujeto activo de su proceso resocializador, aseguran un modelo penal que reduce la tasa de reincidencia y construye una sociedad más cohesionada y participativaOur society structures social relations by way of risk. Fear of the possible loss of our protectedssocial assets has resulted in a change of paradigmsin the nature of penal intervention. There has been a shift from models of responsibility to models of public safety and the identification of the offender as social enemy. However, efficient risk management by the prison administration enables processes effective rehabilitation and rehabilitation. The Therapeutic and Educational Unit at Villabona prison has emerged as one of the penal models that is managing to achieve constitutional ideals. The Unit’s work of effective re-education and design of rehabilitation proposals, with the axis of the action being the prisoners themselves as active subjects of their process of re-socialization, ensure a penal model that significantly reduces recidivism and builds a more cohesive and participative society

Influence of initial power stabilization over PV modules maximum power

Measurements that suppliers offer in flash lists, unfortunately do not always fit the actual power measured in independent laboratories like CIEMAT. In fact, independent measurements usually appear lower than those printed in the label and sometimes a value beyond the allowed tolerance pointed by the manufacturer in the same label. In addition, a valuable power reduction has been reported when Standard IEC - EN 50380 is applied (according to this, PV module must be exposed to sunlight more than 20kWh/m2 previously to performing the measurement), crystalline PV modules usually decrease its power around 1%, but descends greater than 4 % have also been reported. These power losses are only detected after the mentioned power stabilization
