Determinación de cadmio, plomo y ocratoxina en la harina proveniente de las cascarillas de dos variedades de cacao en Ecuador
Authors: El Salous Ahmed , Pascual Alina 
Published: January 2019

En la presente investigación, se evaluó la presencia de cadmio, plomo y ocratoxina en la harina proveniente de las cascarillas de las variedades de cacao Nacional Arriba (cacao nativo, fino o de aroma) y el cacao Colección Castro Naranjal (CCN 51) en Ecuador, para su uso en los procesos de elaboración de galletas y panes.
Se tomaron cinco muestras de 2000 g cada una, de 5 lotes diferentes para cada variedad de cacao en dos industrias cacaoteras en la provincia del Guayas. Se realizó la molienda con un molino marca Oster, se homogenizaron las muestras y se empacaron 700 g de las cáscaras molidas de cada variedad de cacao en fundas de polietileno de baja densidad, para poder realizar la determinación de cadmio, plomo y ocratoxina. Las muestras fueron enviadas a un laboratorio certificado para realizar los análisis correspondientes. Debido a que en Ecuador no existe alguna norma de calidad para la harina proveniente de las cascarillas de cacao, se aplicaron las normas INEN 616 e INEN 621, las cuales definen los requisitos que debe cumplir la harina de trigo y los chocolates respetivamente para que sean aptos para el consumo humano. Los resultados comprueban que la harina proveniente de las cascarillas de ambas variedades cumple con los criterios establecidos en la norma INEN 621 y por consiguiente se garantiza su uso para la elaboración de panes, pasteles o galletas de chocolate como alternativa del uso del cacao en polvo.
On the Maximum Pair Multiplicity of Pulsar Cascades
Authors: Timokhin A. N. , Harding A. K. 
Published: January 2019

Abstract
We study electron–positron pair production in polar caps of energetic pulsars to determine the maximum multiplicity of pair plasma a pulsar can produce under the most favorable conditions. This paper complements and updates our study of pair cascades presented in Timokhin & Harding (2015) with a more accurate treatment of the effects of ultrastrong

G magnetic fields and emission processes of primary and secondary particles. We include pairs produced by curvature and synchrotron radiation photons as well as resonant Compton-scattered photons. We develop a semianalytical model of electron–positron cascades that can efficiently simulate pair cascades with an arbitrary number of microphysical processes and use it to explore cascade properties for a wide range of pulsar parameters. We argue that the maximum cascade multiplicity cannot exceed

and that the multiplicity has a rather weak dependence on pulsar period. The highest multiplicity is achieved in pulsars with magnetic field

and hot surfaces, with T ≳ 106 K. We also derive analytical expressions for several physical quantities relevant for electromagnetic cascade in pulsars, which may be useful in future works on pulsar cascades, including the upper limit on cascade multiplicity and various approximations for the parameter χ, the exponential factor in the expression for photon attenuation in strong magnetic fields.
Dust Pileup at the Dead-zone Inner Edge and Implications for the Disk Shadow
Authors: Ueda Takahiro , Flock Mario , Okuzumi Satoshi 
Published: January 2019

Abstract
We perform simulations of the dust and gas disk evolution to investigate the observational features of a dust pileup at the dead-zone inner edge. We show that the total mass of accumulated dust particles is sensitive to the turbulence strength in the dead zone, α
dead, because of the combined effect of turbulence-induced particle fragmentation (which suppresses particle radial drift) and turbulent diffusion. For a typical critical fragmentation velocity of silicate dust particles of 1 m s−1, the stress-to-pressure ratio α
dead needs to be lower than 3 × 10−4 for dust trapping to operate. The obtained dust distribution is postprocessed using the radiative transfer code RADMC-3D to simulate infrared scattered-light images of the inner part of protoplanetary disks with a dust pileup. We find that a dust pileup at the dead-zone inner edge, if present, casts a shadow extending out to ∼10 au. In the shadowed region the temperature significantly drops, which in some cases yields even multiple water snow lines. We also find that even without a dust pileup at the dead-zone inner edge, the disk surface can become thermally unstable, and the excited waves can naturally produce shadows and ring-like structures in observed images. This mechanism might account for the ring-like structures seen in the scattered-light images of some disks, such as the TW Hya disk.
A Model-independent Mass and Moderate Eccentricity for β Pic b
Authors: Dupuy Trent J. , Brandt Timothy D. , Kratter Kaitlin M. , Bowler Brendan P. 
Published: January 2019

Abstract
We use a cross-calibration of Hipparcos and Gaia second data release astrometry for β Pic to measure the mass of the giant planet β Pic b (13 ± 3

) in a comprehensive joint orbit analysis that includes published relative astrometry and radial velocities. Our mass uncertainty is somewhat higher than previous work because our astrometry from the Hipparcos–Gaia Catalog of Accelerations accounts for the error inflation and systematic terms that are required to bring the two data sets onto a common astrometric reference frame, and because we fit freely for the host-star mass (1.84 ± 0.05 M
⊙). This first model-independent mass for a directly imaged planet is inconsistent with cold-start models given the age of the β Pic moving group (22 ± 6 Myr) but consistent with hot- and warm-start models, concordant with past work. We find a higher eccentricity (0.24 ± 0.06) for β Pic b compared to previous orbital fits. If confirmed by future observations, this eccentricity may help explain inner edge, scale height, and brightness asymmetry of β Pic’s disk. It could also potentially signal that β Pic b has migrated inward to its current location, acquiring its eccentricity from interaction with the 3:1 outer Lindblad resonance in the disk.

Il porte sur la construction d’un monde intérieur, qui n’est différencié d’un extérieur que de façon précaire. Je mets au jour les élaborations logiques qui vont permettre à mon fils Louis, sujet rétif à la division, de s’extraire des premières sensations massives pour ordonner le chaos des éléments, construire une temporalité, élaborer une pensée, s’identifier comme tel dans une vidéo, réaliser qu’on a une valeur aux yeux de l’autre, reconnaître enfin l’autre comme partenaire, De mon côté, il aura fallu en passer par une chute du Savoir, dont j’ai pu me relever en acceptant d’être non pas « autre » mais « plus Un » pour l’accompagner
La personne autiste et sa machine
Authors: Tordo Frédéric 
Published: January 2019

La personne autiste se sent proche des machines, parfois même plus proche que de l’autre humain. Cette parenté intime implique un « branchement » précoce sur la technologie : la personne se « couple » à la machine. C’est pourquoi l’utilisation des robots en psychothérapie semble particulièrement pertinente : d’une part, le robot réactualise le couplage à la machine de la personne autiste ; d’autre part, l’objet possède des caractéristiques du vivant, et de l’humain, qui prépare à une interaction avec un autre, donc également à la relation transférentielle avec le thérapeute.
Autisme et synchronisations sociales. De la clinique à la thérapie
Authors: Barthélémy Catherine 
Published: January 2019

L’approche clinique neuro-fonctionnelle nous éclaire sur les particularités sensorimotrices et émotionnelles qui altèrent les interactions du très jeune enfant autiste avec autrui et le développement de son répertoire d’activité personnelle et de communication. Cette dyspraxie sociale est liée, nous le savons maintenant, à des troubles du développement des réseaux nerveux intracérébraux dits du « cerveau social ». Les études cellulaires, moléculaires et la génétique orientent vers certaines substances-clés qui pourraient constituer la base de futurs médicaments de la connectivité. À ce jour, il n’existe pas de traitement pharmacologique qui guérisse l’autisme. On sait que les interventions rééducatives et éducatives précoces, ciblées et coordonnées, permettent, grâce à la plasticité cérébrale, de relancer la dynamique du développement des réseaux intracérébraux et d’améliorer les fonctionnements adaptatifs et de communication tout au long de la vie.
Posterior Continuous Curvilinear Capsulorhexis With and Without Optic Capture of the Posterior Chamber Intraocular Lens in the Absence of Vitrectomy
Authors: Raina Usha K , Gupta Vinita , Arora Ritu , Mehta D K 
Published: January 2019

ABSTRACT
Purpose: To evaluate the efficacy of posterior continuous curvilinear capsulorhexis (PCCC) with optic capture of the posterior chamber intraocular lens (PC IOL) in the absence of vitrectomy in preventing secondary opacification of the visual axis following pediatric cataract surgery.
Patients and Methods: Thirty-four eyes of 28 children with congenital or developmental cataract, aged 1.5 to 12 years (mean, 6.39 years), were included in this prospective, randomized study. Anterior continuous curvilinear capsulorhexis (ACCC) with PCCC without optic capture of the PC IOL was performed in group A (18 eyes) and ACCC with PCCC with optic capture of the PC IOL was performed in group B (16 eyes). None of the eyes underwent anterior vitrectomy. Secondary opacification of the visual axis, visual acuity, and possible complications were observed and analyzed.
Results: The follow-up period ranged from 8 to 28 months (mean, 17.5 months). All 16 eyes (100%) in group B had a clear visual axis at the end of followup. Eight eyes (44.4%) in group A had significant opacification of the visual axis. The difference between the two groups was statistically significant (P = .0011). No eye in group B required secondary intervention, whereas all 8 eyes in group A with significant secondary opacification required secondary intervention. There was no statistically significant difference in other complications such as anterior chamber reaction, fibrin formation, lenticular precipitates, and posterior synechiae. The final best-corrected visual acuity at the end of follow-up was comparable in the two groups (P > .05).
Conclusion: PCCC with optic capture of the PC IOL prevents secondary opacification of the visual axis even in the absence of vitrectomy.

Early Surgery for Dysthyroid Orbitomyopathy Based on Magnetic Resonance Imaging Findings
Authors: Yolar Murat , Oguz Velittin , Pazarli Halit , Yetik Hüseyin , Özkan Sehirbay 
Published: January 2019

ABSTRACT
Purpose: To investigate the value of magnetic resonance imaging (MRI) in the determination of lhe fibrotic phase in dysfbyroid orbitopathy, which may be an indication for early surgery.
Patients and Methods: Thirteen patients with dysthyroid orbitopathy who had vertical deviation in excess of 20 PD and associated diplopia in the primary position that did not respond to medical treatment were included in the study. On MRI, the absence of high-intensity foci in the T2 sequence, especially in the coronal planes, indicated that the extraocular muscles were not edematous. These muscles were evaluated as being in the fibrotic phase, and surgery was performed without waiting the recommended 6 months for the stabilization of the angle of deviation.
Results: The complaint of diplopia disappeared after a single operation in 8 patients, and after a second operation in 4. Thus, success was obtained in 1 2 of the 1 3 patients. One patient with persistent vertical diplopia refused a second operation.
Conclusion: Our results indicate that MRI is an effective and reliable method for the determination of the fibrotic phase in patients with dysthyroid orbitopathy who have diplopia in the primary position, and that MRI results have an important role in determining whether early surgery is appropriate.
