Objective
	To determine decision to delivery interval in crash caesarean sections .
	To review the risks and benefits associated with crash caesarean section, and ways to achieve swift and safe delivery.
	To know the maternal and fetal outcome of crash caesarean section.
. Methods
This is a 30 month retrospective cross-sectional study at Yenepoya medical college studying Category 1(Crash Cesarean sections) of RCOG cesarean section between July 2017 to December 2019 .A total 509 Crash cesarean sections were analyzed out of 6169 deliveries for decision to delivery interval (DDI) and maternal and fetal outcomes
Results
During the study period there were total of 6169 deliveries of which cesarean section comprised of 1852(30.03%) and 509(8.25%) crash cesarean sections. 82 (16.1%) of crash cesarean sections had DDI of less than 30 min. Neonatal out comes compared as NICU admission in groups with DDI less than 30 min and greater than 30 min had significant p value of 0.0002.Fresh still births(n=2) were present with DDI greater than 30 min. Maternal complications such as bladder injury, traumatic PPH, postoperative wound infections, ICU admissions, negative birth experience were noted.
Conclusion
Monitoring decision to delivery intervals remains essential in assessing quality of obstetric Caesarean section units. For swift and safe C sections, periodic simulation drills are valuable to improve team work, readiness and enhance communication skills.

The Design of the Vehicle Tracker tools using Raspberry
Authors: Hamdani Mohammad 
Published: October 2020

In this paper, it is explained about the design of the Vehicle Tracker tool which is useful in tracking the location of movable assets, by utilizing a GPS receiver USB receiver with a built in antenna, to get coordinates, a Raspberry as a controller and a cellular modem as a media information channel connected to the internet. The controller combines these coordinate information with digital maps obtained from Google Map servers on the internet. When the client accesses the Vehicle Tracker unit via the internet, the controller (Raspberry) provides 'real time' coordinate data along with a digital map. Testing is done by comparing it with GPS Standards with results that are still within the tolerance limit required by GPS International. Latency / delay testing to find out how long the information is sent from the device to the client results in latency / delay under 1 second.

Exoplanet Sciences with Nulling Interferometers and a Single-mode Fiber-fed Spectrograph
Authors: Wang 王 Ji 吉 , Jurgenson Colby 
Published: October 2020

Abstract
Understanding the atmospheres of exoplanets is a milestone to decipher their formation history and potential habitability. High-contrast imaging and spectroscopy of exoplanets is the major pathway toward the goal. Direct imaging of an exoplanet requires high spatial resolution. Interferometry has proven to be an effective way of improving spatial resolution. However, means of combining interferometry, high-contrast imaging, and high-resolution spectroscopy have been rarely explored. To fill in the gap, we present the dual-aperture fiber nuller (FN) for current-generation 8–10 m telescopes, which provides the necessary spatial and spectral resolution to (1) conduct follow-up spectroscopy of known exoplanets and (2) detect planets in debris-disk systems. The concept of feeding an FN to a high-resolution spectrograph can also be used for future space and ground-based missions. We present a case study of using the dual-aperture FN to search for biosignatures in rocky planets around M stars for a future space interferometry mission. Moreover, we discuss how an FN can be equipped on future extremely large telescopes by using the Giant Magellan Telescope as an example.
Lyapunov and Clearing Timescales in Planetary Chaotic Zones
Authors: Shevchenko Ivan I. 
Published: October 2020

Abstract
Debris disks in planetary systems are known to possess gaps “opened” by planets in their close-to-coorbital neighborhoods; the gaps are free from low-mass material such as planetesimals. We consider the escape process of the initially zero-eccentric particles from the gap zone in a scenario consisting of two basic consequent stages: (1) the particle orbit's eccentricity is inflated, while its specific energy is relatively constant, and (2) the particle orbit's semimajor axis is inflated, while its specific angular momentum is relatively constant. During the first stage, the chaotic transport (diffusion) proceeds along the “staircase” of (p + 1):p (with integer p ≫ 1) overlapping particle–planet resonances, and during the second stage, it proceeds along the p:1 particle–planet resonance staircase. A specialized two-dimensional area-preserving map (a “tokamap” version) is derived to describe the first stage, while a multiharmonic Kepler map theory is used to describe the second stage. We derive the μ (mass parameter) scaling for the clearing timescale in the planetary chaotic zone. At small μ, it turns out to be inverse-quadratic in μ. The μ scaling for the Lyapunov timescale inside the gap is also derived. The derived scalings are in qualitative agreement with available numerical-experimental data.
Mitigating Shear-dependent Object Detection Biases with Metacalibration
Authors: Sheldon Erin S. , Becker Matthew R. , MacCrann Niall , Jarvis Michael 
Published: October 2020

Abstract
Metacalibration is a new technique for measuring weak gravitational lensing shear that is unbiased for isolated galaxy images. In this work we test metacalibration with overlapping, or “blended” galaxy images. Using standard metacalibration, we find a few percent shear measurement bias for galaxy densities relevant for current surveys, and that this bias increases with increasing galaxy number density. We show that this bias is not due to blending itself, but rather to shear-dependent object detection. If object detection is shear-independent, no deblending of images is needed, in principle. We demonstrate that detection biases are accurately removed when including object detection in the metacalibration process, a technique we call metadetection. This process involves applying an artificial shear to images of small regions of sky and performing detection on the sheared images, as well as measurements that are used to calculate a shear response. We demonstrate that the method can accurately recover weak shear signals even in highly blended scenes. In the metacalibration process, the space between objects is sheared coherently, which does not perfectly match the real universe in which some, but not all, galaxy images are sheared coherently. We find that even for the worst case scenario, in which the space between objects is completely unsheared, the resulting shear bias is at most a few tenths of a percent for future surveys. We discuss additional technical challenges that must be met in order to implement metadetection for real surveys.

Published: October 2020

Abstract
We report the temporal evolution of the excess brightness temperature ΔT
b above solar active regions (ARs) observed with the Solar Submillimeter Telescope (SST) at 212 (λ = 1.4 mm) and 405 GHz (λ = 0.7 mm) during Cycles 23 and 24. Comparison with the sunspot number (SSN) yields a Pearson’s correlation coefficient R = 0.88 and 0.74 for 212 and 405 GHz, respectively. Moreover, when only Cycle 24 is taken into account the correlation coefficients go to 0.93 and 0.81 for each frequency. We derive the spectral index α between SST frequencies and find a slight anticorrelation with the SSN (R = −0.25); however, since the amplitude of the variation is lower than the standard deviation we cannot draw a definite conclusion. Indeed, α remains almost constant within the uncertainties with a median value of ≈0 characteristic of an optically thick thermal source. Since the origin of the AR submillimeter radiation is thermal continuum produced at chromospheric heights, the strong correlation between ΔT
b and the magnetic cycle evolution could be related to the available free magnetic energy to be released in reconnection events.
The Dynamics, Destruction, and Survival of Supernova-formed Dust Grains
Authors: Slavin Jonathan D. , Dwek Eli , Mac Low Mordecai-Mark , Hill Alex S. 
Published: October 2020

Abstract
Observations have demonstrated that supernovae efficiently produce dust. This is consistent with the hypothesis that supernovae and asymptotic giant branch stars are the primary producers of dust in the universe. However, there has been a longstanding question of how much of the dust detected in the interiors of young supernova remnants can escape into the interstellar medium. We present new hydrodynamical calculations of the evolution of dust grains that were formed in dense ejecta clumps within a Cas A–like remnant. We follow the dynamics of the grains as they decouple from the gas after their clump is hit by the reverse shock. They are subsequently subject to destruction by thermal and kinetic sputtering as they traverse the remnant. Grains that are large enough (∼0.25 μm for silicates and ∼0.1 μm for carbonaceous grains) escape into the interstellar medium while smaller grains get trapped and destroyed. However, grains that reach the interstellar medium still have high velocities, and are subject to further destruction as they are slowed down. We find that for initial grain size distributions that include large (∼0.25–0.5 μm) grains, 10%–20% of silicate grains can survive, while 30–50% of carbonaceous grains survive even when the initial size distribution cuts off at smaller (0.25 μm) sizes. For a 19 M
⊙ star similar to the progenitor of Cas A, up to 0.1 M
⊙ of dust can survive if the dust grains formed are large. Thus we show that supernovae under the right conditions can be significant sources of interstellar dust.
Monte Carlo Calculations of Helium Escape on Mars via Energy Transfer from Hot Oxygen Atoms

Published: October 2020

Abstract
Understanding He escape is crucial for deciphering the evolution of the He budget on Mars. A number of viable mechanisms have been proposed to drive He escape, with energy transfer from hot O generally thought to be the dominant one. This study is devoted to a state-of-the-art evaluation of the above process assuming hot O is exclusively produced from the dissociative recombination of O2
+ in the Martian ionosphere. A Monte Carlo model is constructed, with model inputs optimized by the recent Mars Atmosphere and Volatile Evolution measurements. The model calculations reveal a dayside He escape flux of (1–2) × 106 cm−2 s−1 referred to the surface, for a possible range of H2 mixing ratio at an altitude of 80 km from 0 to 40 ppm. The computed He escape flux increases with increasing nascent O energy and decreasing atmospheric H2 and H abundances. The portion of the atmosphere below the exobase is found to make an exceptionally large contribution of 95% to He escape.
Minutes-delayed Jets from a Neutron Star Companion in Core-collapse Supernovae
Authors: Soker Noam 
Published: October 2020

Abstract
This paper presents cases in which a neutron star (NS; or a black hole) companion to a type-Ib or type-Ic (stripped-envelope) core-collapse supernova (CCSN) accretes mass from the explosion ejecta and launches jets minutes to hours after explosion. The NS orbits at a pre-explosion radius of a ≃ 1−5 R
⊙. When the ejecta velocity drops to

, the ejecta gas that the NS accretes possesses sufficient specific angular momentum to form an accretion disk around the NS. The NS accretes a fraction of

of the ejecta mass through an accretion disk over a time period of

10 minutes–few hr. If the jets carry about 10% of the accretion energy, then their total energy is a fraction of about 0.003−0.03 of the kinetic energy of the ejecta. The implications of these jets from an NS (or a black hole) companion to a CCSN are the shaping of the inner ejecta to have a bipolar morphology, energizing the light curve of the CCSN, and in some cases the possible enrichment of the inner ejecta with r-process elements.

L’auteure fait le récit clinique de son intervention auprès d’un groupe de douze adolescents en pédopsychiatrie. Il s’agit du montage d’une exposition à partir de textes produits lors d’un atelier d’écriture. Cette expérience met en lumière la difficulté de ce type de projet lorsque celui-ci émane d’une commande institutionnelle, en partenariat avec un service culturel de la ville, pour une exposition destinée au grand public. Comment concilier les attentes institutionnelles, les contraintes du lieu accueillant, et la nécessaire préservation de l’intimité des adolescents ? Dans l’après-coup de cette expérience, un travail de mise en sens a émergé, apportant un éclairage théorico-clinique sur le vécu des jeunes et de l’équipe de soin.
Le degré de sécurité d’attachement et les comportements problématiques des enfants présentant un trouble du spectre de l’autisme
Authors: Lapointe Marilyn , Poirier Nathalie , Abouzeid Nadia 
Published: October 2020

La présente étude vise à décrire les liens entre le degré de sécurité d’attachement et les comportements problématiques des enfants présentant un trouble du spectre de l’autisme (TSA) tout en contrôlant l’effet modérateur du stress parental et du niveau de sévérité de l’autisme. Les résultats des questionnaires répondus par 39 parents d’enfants présentant un TSA démontrent que la diminution du degré de sécurité d’attachement des enfants présentant un TSA est significativement liée à la présence de certains comportements problématiques ; tels que les comportements de retrait et les comportements d’inattention. De ce fait, les conclusions de l’étude proposent l’application d’une intervention relationnelle auprès des familles d’enfants présentant un TSA en complémentarité aux autres interventions efficaces dans le domaine du TSA.
La fiction de l’adolescence comme quête du moi et critique du fascisme : Les Indifférents d’Alberto Moravia
Authors: Puel Blandine 
Published: October 2020

En 1929 paraît le premier roman d’Alberto Moravia, Gli Indifferenti, alors que la dictature fasciste est à son apogée. Cette fiction, amorale à souhait, interroge effrontément les dérives d’une époque en crise imposant à tous un conformisme identitaire calqué sur l’image glorieuse du « Duce ». Michel et Carla, deux adolescents en quête d’une définition honnête d’eux-mêmes, incarnent ce questionnement par leurs hésitations et leur doute existentiel.
Confusion à la Maison Blanche : la bataille du pouvoir entre Hillary Clinton et Al Gore
Authors: Loizeau Pierre-Marie 
Published: October 2020

Cet article s’attache à analyser la rivalité entre Hillary Clinton et Al Gore durant la présidence Clinton. Les réformes successives de la fonction de vice-président ont permis à celui-ci de tenir progressivement le rang de n° 2 au sein de l’Exécutif. En inversant la tendance au profit de la Première Dame, l’administration Clinton instaura une rivalité de pouvoir entre seconds couteaux. L’échec de la réforme du Système de Santé écarta Mme Clinton et rétablit une collaboration plus traditionnelle entre le président et le vice-président. En fin de mandat, le scandale Lewinsky entraîna le discrédit de toute l’administration y compris du vice-président et de la Première Dame.
Relación entre rendimiento académico y estilos de aprendizaje

Published: October 2020

En el año 2000 la Universidad de San Carlos de Guatemala implemento el Programa Académico Preparatorio -PAP- constituyéndose en un programa permanente, continuo y sistemático, cuyo propósito es nivelar los conocimientos de ciencias básicas de los aspirantes a ingresar a la USAC, que obtienen un resultado insatisfactorio en las Pruebas Básicas. Cada año se inscriben al PAP 1200 estudiantes, de los cuales solo el 25% logra obtener resultado satisfactorio, dejando la inquietud de conocer cuáles son los estilos de aprendizaje de los estudiantes del PAP y sus efectos en el rendimiento académico. El objetivo de la investigación es identificar los estilos de aprendizaje y su relación con el rendimiento académico, la población fue de 418 estudiantes, de 8 secciones entre las edades de 16 a 32 años, de los cuales 104 fueron mujeres y 314 hombres, para conocer los estilos de aprendizaje se aplicó una escala de Likert, con valores de acuerdo y desacuerdo en escala de 1 a 5, dando como resultado que 301 alumnos tiene un aprendizaje visual, 78 un aprendizaje auditivo y 39 un aprendizaje kinestésico. Predominando el aprendizaje visual con el 72% de la población total. Para identificar la relación entre estilos de aprendizaje y rendimiento académico se realizó un análisis correlación lineal, entre la nota obtenida en el curso de matemática y el valor promedio (de 1 a 5) obtenido en la escala de Likert, dando como resultado que ninguno de los estilos de aprendizaje está relacionado con el rendimiento académico.

Published: October 2020

Se investigó el tema de currículo contextualizado, los contenidos, elementos, procesos, sujetos de aprendizaje bajo un contexto real del estudiante, en el departamento de El Progreso. Fundamentando los análisis y propuestas sobre educación, por citar algunos: Elam (1973), Ausubel (1976), Novack (1977) Eisner y Vallancer (1984); quienes consideran, reconstrucción social, estructuración significativa, racionalismo académico y desarrollo de procesos cognitivos. Se diseñó mediante una investigación científica mixta, con datos cuantitativos y cualitativos, y triangulándose los resultados. Justificándose la investigación con los objetivos de la educación para responder a características, necesidades y aspiraciones de un país multicultural, multilingüe y multiétnico; respetando, fortaleciendo y enriqueciendo la identidad personal y la de sus pueblos. Es un estudio analítico sobre currículo contextualizado, por medio de una metodología de investigación descriptiva, diseñada y aplicada mediante tres instrumentos, tomando como muestra a autoridades administrativas, docentes y estudiantes. Los principales resultados recogen información que los programas no proponen experiencias del contexto sociocultural del departamento, los conocimientos y experiencias en los planes de estudio no permiten a los estudiantes tener una visión unificada del conocimiento y un significado de su identidad sociocultural, las actividades no están diseñadas para enriquecer la identidad cultural de los educandos y que su diseño no ha sido elaborado para dicho contexto. En conclusión, el diseño curricular investigado, debe de ser contextualizado y socializado por medio de una planificación de currículo contextualizado a cargo de docentes y supervisado por autoridades del centro universitario.
