La educación en contextos de diversidad cultural: un estudio sobre educadores brasileños
Authors: Martínez-Otero Pérez Valentín 
Published: March 2021

Este artículo se interesa por la educación en contextos de diversidad cultural y por la perspectiva de los educadores sobre sus necesidades formativas. Se utilizó un cuestionario diseñado ad hoc y se opta por un método mixto, cuantitativo y cualitativo, mediante un diseño complementario de fases paralelas (diseño anidado) Cuan-cual. El cuestionario se aplicó a una muestra de 237 educadores brasileños. Los resultados revelan que la atención a la diversidad cultural ocupa un papel importante en la actividad educativa. Los educadores, en su conjunto, son sensibles a la diversidad cultural y a su fomento, pero la formación intercultural recibida es insuficiente. Se fomenta poco la participación familiar, los recursos escasean y la dimensión intercultural carece de sistematización pedagógica

The true teenager is the hope of a nation, the country will become strong if it has teenagers who are spiritually intelligent, intellectually and have a strong emotional. As the rapid development of the world makes changes in behavior in adolescents, but these changes are more likely to lead to negative activities rather than positive activities. Problems that often arise are usually related to sexuality issues, such as unwanted pregnancy, abortion, HIV / AIDS, and drug abuse. Adolescents with these behavioral deviations need a treatment and also get information about reproductive health for young women and men, need to organize a good future by leaving unwholesome behavior that can damage the future of adolescents. Going through adolescence far from deviant behavior would certainly be our common concern. Teenagers will not be able to walk on their own without the assistance of parents, the school, home and etc. Realizing this, the Community Service Study Program of the Midwifery Study Program at the Faculty of Health, Ngudi Waluyo University, felt responsible for facilitating adolescents to learn to understand and be able to practice healthy behaviors to become adolescents who had strong hopes for the nation. Community Service is carried out in 5 stages, namely the first phase of selecting active groups of students who are willing to be agents of change for GenRe / willing to be peer educators, the second stage of counseling and training of peer educators. The third stage of mentoring is increasing peer group skills in providing information to peers. Stage four peer educators independently socialize GenRe to peers. The Fifth stage evaluates the delivery of information from peer educators to their peers, explores the usefulness of the existence of peer educators, limitations and new things that arise when becoming a peer educator.Keywords: Generation planning, peer educators

The stage of growth and development of school-age children and preschoolers is a golden age stage. This age stage all development systems including the brain work optimally. Children receive sensory and motoric responses well and are interested in new things. But unfortunately there are some exposure that is not good that should not be done at this age, such as gadgets. Access to using a mobile phone that is felt to be increasingly easy to obtain, in fact it will hamper children's development. Children become lazy to move and just like to play mobile. Although on the other hand, not all applications on mobile phones have a bad impact on children, there are also learning applications that can be used by children. Parents need to be wise in dealing with this situation, so that children do not experience addiction to play mobile phones. The impact of gadget addiction on children can vary from unstable emotions or disturbances to social interaction damage. A variety of outdoor and indoor physical activities can be used to divert the attention of children on mobile phones, one of them by doing brain gymnastics or brain gym. Brain gymnastics is a simple exercise that can stimulate brain work activities and is easily done by children. This activity was introduced in the preschool and school age groups by the service team in the community of children who joined the Domus Dei prayer meeting. The children explained that this was their first experience and was an exciting and exciting activity. The children also explained that they would repeat it again at home with both their parents and their caregivers. The purpose of this activity is to increase the interaction of children with the same age as parents and caregivers, and to introduce brain exercise skills to children. The method of activities carried out is counseling and brain exercise training in children. The results of this activity are all children appear active and happy to do brain exercise activities together. Conclusion: Brain gym activity can improve children's interactions with peer groups, and also with parents and caregivers Keywords: Children, Brain Gymnastics

Published: March 2021

Abstract
Most ultrasound contrast agents used in ultrasonic imaging comprise shell-encapsulated microbubbles, whose ingredients have been associated with adverse bioeffects. In this study, we investigated the nucleation behaviour of carbon black dispersion, whose hydrophobic nanoparticles are used intradermally. For a hypothetical, perfectly spherical carbon black particle surrounded by a perfectly spherical gaseous void, we derived a theoretical nucleation threshold of only 1.3× the resting radius. Carbon black particles and aggregates thereof were investigated using high-speed photography during 1.0 MHz sonication. The nucleation threshold found experimentally is lower than the Blake cavitation threshold of 2.0× the resting radius of free, unencapsulated microbubbles. Therefore, carbon black dispersion may be a promising ultrasound contrast agent.

A solidly mounted, high frequency, thickness shear mode bulk acoustic wave resonator using X-LiTaO3 thin plate and SiO2/Ta multilayer acoustic films
Authors: Kadota Michio , Ishii Yoshimi , Tanaka Shuji 
Published: March 2021

Abstract
This paper describes a bulk acoustic wave (BAW) high-frequency resonator with a solidly mounted structure using a single crystal LiTaO3 (LT) thin plate. A Bragg reflector solidly supports the LT thin plate, which is fragile if self-suspended. The BAW resonator uses a thickness shear mode in 1.5 μm thick X-LT. The Bragg reflector is made of four pairs of SiO2 and Ta films, i.e. eight layers in total. The fabricated device works at a resonance frequency of 1.14 GHz and an antiresonance frequency of 1.23 GHz, showing a bandwidth of 7.9% and a low-temperature coefficient of frequency of −16 ppm °C−1 and −26 ppm °C−1 at the maximum and minimum admittances, respectively. The measured impedance ratio is 61 dB, although the structure and fabrication process are not optimized yet, suggesting a high potential for this device.

A feeding trial was conducted to determine the growth performance and carcass characteristics of Japanese quails fed diets containing sorghum. A total of ninety of one-week old Japanese quail chicks were used for the experiment. Five diets were formulated in which sorghum was included at graded levels 0, 15, 30, 45 and 60% dietary levels designated as treatment 1, 2, 3, 4 and 5 respectively. The experimental period was five weeks when the birds reach six weeks of age. The results of the growth performance showed significant differences (P<0.05) in the final body weight (161.70 – 180.10 g) and daily feed intake (21.34–25.12 g). Significant (P<0.05) differences was also observed in all carcass parameters measured except for dressing percentage. Liver weight and large intestine with T5 (65% total replacement) recorded the highest means value of 6.00 g and 6.66 g. Non-significant high values of feed conversion ratio were also obtained among the treatments. Treatment 1 (0%) and Treatment 5 (60%) showed better results in all parameters measured compared to other treatments. In conclusions, sorghum grain can play a significant role in formulating quail feed and can completely (60%) be used to replace maize without affecting the performance and carcass yield of the quails.
EXPERTOS EN FISIOLOGÍA: RESUMEN DE LO QUE DEBES SABER DE LAS HORMONAS TIROIDEAS
Authors: Lam de Calvo Oris , Castillero de Santos Lilibeth 
Published: March 2021

La glándula tiroides secreta dos hormonas importantes, la tiroxina y triyodotironina. Se conoce ahora, una regulación más selectiva de la síntesis de triyodotironina a partir de la desyodación de tiroxina en los tejidos blanco; esto permite una mayor disponibilidad de hormona en un determinado tejido, de acuerdo con sus necesidades fisiológicas, o lo protege de los niveles exageradamente altos. La glándula tiroides tiene la capacidad de almacenar y autorregular el ingreso de yodo a la misma y de desviar la síntesis hormonal hacia la triyodotironina ante escasa ingesta de yodo. Además de los receptores nucleares, se conocen otros receptores para las hormonas tiroideas, localizados en las mitocondrias y en la superficie de la membrana plasmática, y sus efectos son esenciales en el desarrollo, crecimiento y metabolismo.
"El volante" de César Aira o cómo no escribir una novela

Published: March 2021

En este artículo pretendemos analizar las implicaciones que se derivan de enunciaciones autoficcionales de carácter fantástico y su relación con el humor en la obra El volante (1992) del autor argentino César Aira. En ella, la parodia y lo inverosímil promueven una lectura fantástica y absurda en una historia saturada de elementos humorísticos y paródicos, donde diferentes niveles diegéticos complejizan las nociones de realidad a través de juegos metalépticos en los que el autor se autonarra “actuando” como personaje caricaturizado.
Investigación artística en música

Published: March 2021

En un contexto en el que la investigación artística en música (artistic research) se abre camino cada vez más rápido en el panorama educativo y en el que los estudiantes demandan nuevas propuestas centradas en la investigación en las artes musicales, este artículo explora la oferta educativa a nivel de doctorado que, en la actualidad, está vigente en universidades y conservatorios superiores de música en Europa.
Con un objetivo fundamentalmente práctico, se ofrece un estado de la cuestión que reflexiona sobre los parámetros fundamentales que todo estudiante que desee adentrarse en esta vía de investigación artística debe considerar. Asimismo, se recoge en una tabla adjunta la diversidad de títulos que contemplan este enfoque y se desglosan diversos parámetros que abarcan desde requisitos de admisión, hasta idiomas en los que se imparten estos estudios, créditos, duración, instituciones colaboradoras, formato de presencialidad, mecanismos de seguimiento, cuestiones relacionadas con la defensa de la tesis, áreas de estudio, precios y modalidades de financiación, entre otros aspectos. De esta manera, quienes se acerquen a este trabajo podrán seleccionar el centro que mejor se adecúe a sus necesidades, al mismo tiempo que obtendrán una visión global en torno al programa seleccionado.
En suma, este artículo ofrece respuestas a la demanda actual de los músicos en la búsqueda de programas doctorales que unifiquen tanto la vía interpretativa/compositiva como la de investigación, y que se alejen de los enfoques tradicionales que, a veces únicos hace poco tiempo, ofertaban los centros de enseñanza superior. No dudamos que, con el tiempo, tanto esta tabla como el artículo se ampliarán, en paralelo a la difusión y adaptación que los centros hagan con este nuevo enfoque de estudios que se abre paso de forma lenta pero segura.

Cometary Activity Begins at Kuiper Belt Distances: Evidence from C/2017 K2
Authors: Jewitt David , Kim Yoonyoung , Mutchler Max , Agarwal Jessica , Li Jing , Weaver Harold 
Published: March 2021

Abstract
We study the development of activity in the incoming long-period comet C/2017 K2 over the heliocentric distance range 9 ≲ r

H
≲ 16 au. The comet continues to be characterized by a coma of submillimeter-sized and larger particles ejected at low velocity. In a fixed co-moving volume around the nucleus we find that the scattering cross section of the coma, C, is related to the heliocentric distance by a power law,

, with heliocentric index s = 1.14 ± 0.05. This dependence is significantly weaker than the r

H

−2 variation of the insolation as a result of two effects. These are, first, the heliocentric dependence of the dust velocity and, second, a lag effect due to very slow-moving particles ejected long before the observations were taken. A Monte Carlo model of the photometry shows that dust production beginning at r

H
∼ 35 au is needed to match the measured heliocentric index, with only a slight dependence on the particle size distribution. Mass-loss rates in dust at 10 au are of order 103 kg s−1, while loss rates in gas may be much smaller, depending on the unknown dust to gas ratio. Consequently, the ratio of the nongravitational acceleration to the local solar gravity, α′, may, depending on the nucleus size, attain values of ∼10−7 ≲ α′ ≲ 10−5, comparable to values found in short-period comets at much smaller distances. Nongravitational acceleration in C/2017 K2 and similarly distant comets, while presently unmeasured, may limit the accuracy with which we can infer the properties of the Oort cloud from the orbits of long-period comets.
Gyro-kinematic Ages for around 30,000 Kepler Stars

Published: March 2021

Abstract
Estimating stellar ages is important for advancing our understanding of stellar and exoplanet evolution and investigating the history of the Milky Way. However, ages for low-mass stars are hard to infer as they evolve slowly on the main sequence. In addition, empirical dating methods are difficult to calibrate for low-mass stars as they are faint. In this work, we calculate ages for Kepler F, G, and crucially K and M dwarfs, using their rotation and kinematic properties. We apply the simple assumption that the velocity dispersion of stars increases over time and adopt an age–velocity-dispersion relation (AVR) to estimate average stellar ages for groupings of coeval stars. We calculate the vertical velocity dispersion of stars in bins of absolute magnitude, temperature, rotation period, and Rossby number and then convert velocity dispersion to kinematic age via an AVR. Using this method, we estimate gyro-kinematic ages for 29,949 Kepler stars with measured rotation periods. We are able to estimate ages for clusters and asteroseismic stars with an rms of 1.22 Gyr and 0.26 Gyr respectively. With our Astraea machine-learning algorithm, which predicts rotation periods, we suggest a new selection criterion (a weight of 0.15) to increase the size of the McQuillan et al. catalog of Kepler rotation periods by up to 25%. Using predicted rotation periods, we estimated gyro-kinematic ages for stars without measured rotation periods and found promising results by comparing 12 detailed age–element abundance trends with literature values.
