Flipped classroom in primary education teacher’s degree: strength and weakness

[EN] This article presents the results of an innovation experience carried out with first year students of the Primary Education Teacher’s Degree. Based on global trends in favour of curricular methodologies to encourage the development of autonomous and collaborative learning capacities in students, a group of teacher’s members of the Educational Innovation Group EIEGID, who teach in the subject School Organization and Resources in Education, has sought a progressive graduation in the difficulty and prominence to be assumed by the students in the learning tasks. The aim was to overcome the dichotomy of theoretical classes and practical classes, contemplating different methodologies, but sharing their features: foster student autonomy, seek motivation, take risks and develop alternative responses, promoting responsibility, with options to experiment and encourage the development of an attitude of permanent improvement. To do this, tasks are proposed that allowed to face unforeseen events, t[ES] Este artículo presenta los resultados de una experiencia de innovación realizada con alumnos de primer curso del Grado de Maestro de Educación Primaria. Partiendo de las tendencias globales a favor del fomento de capacidades de aprendizaje autónomo y colaborativo, un grupo de profesores miembros del Grupo de Innovación Docente EIE-GID, ha buscado una graduación progresiva en la dificultad y protagonismo a asumir por el alumnado en las tareas de aprendizaje. Se busca superar la dicotomía de clases teóricas y clases prácticas, empleando metodologías diversas, pero que comparten entre sus rasgos: fomentar la autonomía del alumno, procurar la motivación, adopción de riesgos y elaboración de respuestas alternativas, promoviendo responsabilidad, con opciones de experimentar y estimular el desarrollo de una actitud de superación permanente. Para ello, se plantean tareas que permiten hacer frente a acontecimientos imprevistos, tomar iniciativas, ser responsables y autónomos, movilizar recursosGarcía Hernández, M.; Porto Currás, M.; Hernández Valverde, F.

ISOLAMENTO DO Ureaplasma diversum EM MUCO VULVOVAGINAL DE VACAS LEITEIRAS REPETIDORAS DE ESTRO NO ESTADO DE ALAGOAS BRASIL

Ureaplasma diversum is an opportunistic bacteria of the bovine genital tract and an important agent in granular vulvovaginitis, abortion, low fertility herd rate and respiratory problems in calves. The aim of this work was to study the relationship between positive cultures for Ureaplasma diversum and the extension and severity of the lesions in the vaginal mucosa of repeat breeders dairy cows in Alagoas State, Brazil. Visual evaluation were performed in 93 cows to evaluate the vaginal lesion score (VLS), classified according the lesion severity and extension (0 to 4, with 0= no lesions, 4= severe inflammation and local necrosis). The VLS 1 was the most frequent (51,61%). VLS 0 was present in 17,2% of the females, while 29,03% and 2,16% showed VLS 2 and 3, respectively. None of the cows showed VLS 4. Vaginal swab samples were obtained from 24 females (25%). Of them, 41,7% were positive for U. diversum. The presence of U. diversum was associated positively to VLS, especially to those cows showing vaginal lesion score 1. The present results indicated that Ureaplasma diversum should be considered responsible for low reproductive efficiency, carrying out to repeat breeding, probably because of embryo mortality.O Ureaplasma diversum é um patógeno oportunista do trato genital dos bovinos que causa surtos de vulvovaginite granular, seguidos de abortamento e redução da eficiência reprodutiva do rebanho. O presente estudo foi desenvolvido com o objetivo de avaliar a relação entre a extensão e a gravidade das lesões de vulvovaginite observadas com o isolamento de Ureaplasma diversum em amostras colhidas diretamente da mucosa vulvovaginal, em fêmeas de aptidão leiteira repetidoras de estro no estado de Alagoas, Brasil. A avaliação da extensão e severidade das lesões foi feita em 93 vacas com histórico de repetição regular de estro após três ou mais inseminações artificiais, seguindo-se a seguinte metodologia de classificação: graus de 0 a 4, sendo 0=sem lesões; 4=lesões severas, com hemorragia e necrose. Dos 93 animais avaliados, 17,2% apresentavam lesão grau 0; 51,61% grau 1; 29,03% grau 2; 2,16% grau 3 e nenhum animal mostrou lesão de grau 4. Foi colhido muco vulvovaginal de 24 vacas, escolhidas aleatoriamente, para processamento bacteriológico, encontrando-se 41,67% das amostras positivas para Ureaplasma diversum. O isolamento do agente esteve positivamente relacionado à presença de lesões na mucosa vulvovaginal, especialmente àquelas de grau 1. Os resultados deste estudo indicam que o Ureaplasma diversum deve ser considerado como agente responsável por queda na eficiência reprodutiva, promovendo retorno ao estro, provavelmente em conseqüência de mortalidade embrionária

Light scattering from disordered overlayers of metallic nanoparticles

We develop a theory for light scattering from a disordered layer of metal nanoparticles resting on a sample. Averaging over different disorder realizations is done by a coherent potential approximation. The calculational scheme takes into account effects of retardation, multipole excitations, and interactions with the sample. We apply the theory to a system similar to the one studied experimentally by Stuart and Hall [Phys. Rev. Lett. {\bf 80}, 5663 (1998)] who used a layered Si/SiO$_2$/Si sample. The calculated results agree rather well with the experimental ones. In particular we find conspicuous maxima in the scattering intensity at long wavelengths (much longer than those corresponding to plasmon resonances in the particles). We show that these maxima have their origin in interference phenomena in the layered sample.Comment: 19 pages, 12 figure

Local mean-field study of capillary condensation in silica aerogels

We apply local mean-field (i.e. density functional) theory to a lattice model of a fluid in contact with a dilute, disordered gel network. The gel structure is described by a diffusion-limited cluster aggregation model. We focus on the influence of porosity on both the hysteretic and the equilibrium behavior of the fluid as one varies the chemical potential at low temperature. We show that the shape of the hysteresis loop changes from smooth to rectangular as the porosity increases and that this change is associated to disorder-induced out-of-equilibrium phase transitions that differ on adsorption and on desorption. Our results provide insight in the behavior of $^4$He in silica aerogels.Comment: 19 figure

Mass and charge identification of fragments detected with the Chimera Silicon-CsI(Tl) telescopes

Mass and charge identification of charged products detected with Silicon-CsI(Tl) telescopes of the Chimera apparatus is presented. An identification function, based on the Bethe-Bloch formula, is used to fit empirical correlation between Delta E and E ADC readings, in order to determine, event by event, the atomic and mass numbers of the detected charged reaction products prior to energy calibration.Comment: 24 pages, 7 .jpg figures, submitted to Nucl.Instr.

Status and perspectives of the 4 pi charged particles multidetector CHIMERA

The construction of the multidetector CHIMERA designed to detect and identify charged particles and fragments emitted in heavy ion reactions at intermediate energy is in progress and is coming to an end. The construction of this multidetector is presented in this paper as well as the status of the project
