Photometry of the Uranian Satellites with Keck and the Search for Mab

Published: October 2019

Abstract
We present photometric properties of six small (radii <100 km) satellites of Uranus based on 32 H-band (1.49–1.78μm) images taken on 2015 August 29 from the Keck II Telescope on Maunakea, Hawaii with the near-infrared camera NIRC2 coupled to the adaptive optics system. The sub-observer latitude of our observations was 32°, i.e., we view much of the satellites’ north poles, in contrast to the 1986 Voyager measurements. We derive reflectivities based on mean-stacking measurements of these six minor moons of Uranus. We find that the small satellites are significantly brighter than in previous observations, which we attribute to albedo variations between hemispheres. We also search for Mab, a small satellite with an unknown surface composition, orbiting between Puck and Miranda. Despite the significantly improved signal-to-noise ratio we achieved, we could not detect Mab. We suggest that Mab is more similar to Miranda, an icy body, than to the inner rocky moons. Assuming Mab is spherical with a radius of 6 km, as derived from Hubble Space Telescope (HST) observations if its reflectivity is ∼0.46, we derive a 3σ upper limit to its reflectivity [I/F] of 0.14 at 1.6 μm.

Abstract
Here we present new ALMA observations of polarized dust emission from six of the most massive clumps in W43-Main. The clumps MM2, MM3, MM4, MM6, MM7, and MM8, have been resolved into two populations of fragmented filaments. From these two populations we extracted 81 cores (96 with the MM1 cores) with masses between 0.9 M
⊙ to 425 M
⊙ and a mass sensitivity of 0.08 M
⊙. The MM6, MM7, and MM8 clumps show significant fragmentation, but the polarized intensity appears to be sparse and compact. The MM2, MM3, and MM4 population shows less fragmentation, but with a single protostellar core dominating the emission at each clump. Also, the polarized intensity is more extended and significantly stronger in this population. From the polarized emission, we derived detailed magnetic field patterns throughout the filaments that we used to estimate field strengths for four out of the six clumps. The average field strength estimates were found to lie between 500 μG to 1.8 mG. Additionally, we detected and modeled infalling motions toward MM2 and MM3 from single-dish

and

data, resulting in mass infall rates of

M
⊙ yr−1 and

M
⊙ yr−1. Using our estimations, we evaluated the dynamical equilibrium of our cores by computing the total virial parameter α
total. For the cores with reliable field estimates, we found that 71% appear to be gravitationally bound while the remaining 29% are not. We conclude that these unbound cores, which are also less massive, are still accreting and have not yet reached a critical mass. This also implies different evolutionary timescales, which essentially suggests that star formation in high-mass filaments is not uniform.
Cooling+Heating Flows in Galaxy Clusters: Turbulent Heating, Spectral Modeling, and Cooling Efficiency
Authors: Zhoolideh Haghighi Mohammad H. , Afshordi Niayesh , Khosroshahi Habib. G. 
Published: October 2019

Abstract
The discrepancy between expected and observed cooling rates of X-ray emitting gas has led to the cooling-flow problem at the cores of clusters of galaxies. A variety of models have been proposed to model the observed X-ray spectra and resolve the cooling-flow problem, which involves heating the cold gas through different mechanisms. As a result, realistic models of X-ray spectra of galaxy clusters need to involve both heating and cooling mechanisms. In this paper, we argue that the heating timescale is set by the magnetohydrodynamic (MHD) turbulent viscous heating for the Intracluster plasma, parameterized by the Shakura–Sunyaev viscosity parameter, α. Using a cooling+heating flow model, we show that a value of α ≃ 0.05 (with 10% scatter) provides improved fits to the X-ray spectra of cooling flow, while at the same time, predicting reasonable cooling efficiency,

. Our inferred values for α based on X-ray spectra are also in line with direct measurements of turbulent pressure in simulations and observations of galaxy clusters. This simple picture unifies astrophysical accretion, as a balance of MHD turbulent heating and cooling, across more than 16 orders of magnitudes in scale, from neutron stars to galaxy clusters.
Fingerprints of the Protosolar Cloud Collapse in the Solar System. II. Nucleosynthetic Anomalies in Meteorites
Authors: Jacquet Emmanuel , Pignatale Francesco C. , Chaussidon Marc , Charnoz Sébastien 
Published: October 2019

Abstract
The isotopic heterogeneity of the solar system shown by meteorite analyses is more pronounced for its earliest objects, the calcium–aluminum-rich inclusions (CAIs). This suggests that it was inherited from spatial variations in stardust populations in the protosolar cloud. We model the formation of the solar protoplanetary disk following its collapse and find that the solid-weighted standard deviation of different nucleosynthetic contributions in the disk is reduced by one order of magnitude compared to the protosolar cloud, whose successive isotopic signatures are fossilized by CAIs. The enrichment of carbonaceous chondrites in r-process components, whose proportions are inferred to have diminished near the end of infall, is consistent with their formation at large heliocentric distances, where the early signatures would have been preferentially preserved after outward advection. We also argue that thermal processing had little effect on the (mass-independent) isotopic composition of bulk meteorites for refractory elements.
Inductive Acceleration of Ions in Poynting-flux-dominated Outflows
Authors: Kirk John G. , Giacinti Gwenael 
Published: October 2019

Abstract
Two-fluid (electron–positron) plasma modeling has shown that inductive acceleration can convert Poynting flux directly into bulk kinetic energy in the relativistic flows driven by rotating magnetized neutron stars and black holes. Here, we generalize this approach by adding an ion fluid. Solutions are presented in which all particles are accelerated as the flow expands, with comparable power channeled into each of the plasma components. In an ion-dominated flow, each species reaches the limiting rigidity, according to Hillas’ criterion, in a distance significantly shorter than in a lepton-dominated flow. These solutions support the hypothesis that newly born magnetars and pulsars are potential sources of ultrahigh energy cosmic rays. The competing process of Poynting flux dissipation by magnetic reconnection is shown to be ineffective in low-density flows in which the conventionally defined electron multiplicity satisfies

, where L
38 × 1038 erg s−1 is the power carried by the flow in a solid angle Ω, and

is the ratio of the ion to lepton power at launch.
Repeated Coronal Condensations Caused by Magnetic Reconnection between Solar Coronal Loops

Published: October 2019

Abstract
We recently presented coronal condensations, caused by magnetic reconnection (MR) between coronal loops from extreme ultraviolet observations, over the course of one day, on 2012 January 19. In this paper, by investigating the loops over an extended period of time from January 16 to 20, we present a case for repeated coronal condensations caused by repeated MR between them. In these five days, MR between higher-lying open loops and lower-lying closed loops occurs repeatedly, forming magnetic dips in the higher-lying open loops. During the MR process, cooling and condensation of coronal plasma occur repeatedly. Early on January 16, cooling, but not condensation, of coronal plasma happens. Later, condensation appears at the edge of the dips and falls down along the loops as coronal rains. On January 17, a similar condensation happens at the edge of the higher-lying dips and falls down along the loops. However, another condensation appears in the lower-lying dips and rains down across them. From January 18 to 19, multiple condensations mostly occur at the edge of the dips and fall down both along the loops and across the dips. On January 20, five condensations sequentially appear and rain down across the dips. Overall, 15 condensation events occur in five days, lasting from 0.5 to 15.6 hr. We suggest that the formation of coronal condensations by MR between loops is common in the solar corona. The repeated MR between loops thus plays an essential role in the mass cycle of coronal plasma by initiating repeated catastrophic cooling and condensation.
Correction of Class II Malocclusion with Skeletal Deep Bite

Published: October 2019

ABSTRACT
Correction of skeletal deformities in adult patients with orthodontics is limited. In adult severe cases, the combined approach, orthodontic and orthognathic surgery, is always the treatment of choice, and the results obtained usually ensure a better esthetics, functionality, and stability. Orthognathic surgery is the best option for cases when camouflage treatment is questionable and growth modulation is not possible. This case report illustrates the benefit of the team approach in correcting mandible retrusion along with class II skeletal deformity with 100% deep bite. Insertion of fixed functional appliance was not possible due to prominent root apices and thin mandible cortical plates. Correction was achieved by anterior repositioning of mandible osteotomy along with orthodontic treatment. The patient's facial appearance was markedly improved along with functional and stable occlusion.

Prevalence of Anemia in both Developing and Developed Countries around the World
Authors: Prasanth Rajalakshmy 
Published: October 2019

ABSTRACTAnemia is a major nutritional problem worldwide and is mainly caused due to iron deficiency. Though it is global in occurrence, it is more of a concern in the developing countries where it is always associated with the socioeconomic status of the people. Anemia is very high (ranging between 80 and >90%) in preschool children, adolescent girls, and pregnant and lactating women. There are about 1.2 billion adolescents in the world, which is equal to one-fifth of the world's population and their numbers are increasing. This study deals with the prevalence of anemia in the different nations of the world.How to cite this articlePrasanth R.

A história universal entre a escrita da história e a travessia atlântica: produção e circulação de compêndios escolares franceses e brasileiros (1820-1864)
Authors: Barnabé Luis Ernesto 
Published: October 2019

O Précis de l'Histoire Ancienne, de Charles Cayx e Auguste Poirson, juntamente com outros quatro précis, integrava uma inovadora proposta de um curso de História para os collèges royaux franceses. Essa coleção, concluída em 1830, seria adotada pelo governo brasileiro em 1838, na forma de tradução, para o recém-inaugurado Imperial Colégio de Pedro II. O objetivo deste artigo é fazer uma análise que entrecruze, por um lado, a acomodação entre as perspectivas de História Universal de Bossuet e iluminista de Heeren – resultado do exercício de uma escrita da História sob a especificidade tanto do suporte (o précis) quanto do público para qual se destinava – e, por outro, o fato de esta escrita da História integrar projetos de nação e civilização do Império brasileiro ao atravessar o Atlântico. Desta análise se constatam tensões e disputas pela construção de inteligibilidade da história num campo de batalha que não era exclusivo dos historiadores: o compêndio escolar.
Parceiros em quê? A Aliança para o Progresso e a política editorial de modernização da América Latina no contexto da Guerra Fria
Authors: Ioris Rafael R. , Mozer Josiane 
Published: October 2019

A Aliança para o Progresso, política elaborada pelo governo Kennedy, no início dos anos 1960, com fins de promover o desenvolvimento nos moldes capitalistas na América Latina, assentava-se sob um dilema de difícil conciliação. Por um lado, as demandas da região por desenvolvimento econômico não poderiam mais ser ignoradas; por outro, percebia que um desenvolvimento autônomo da América Latina, nos moldes idealizados pela Aliança, poderia levar a uma diminuição da influência regional dos Estados Unidos. Entre as pressões dos países latino-americanos e os interesses hegemônicos dos Estados Unidos, a Aliança foi rapidamente assumindo contornos coercitivos e ideológicos, esvaziando de sentido a proposta de parceria para o bem comum. Baseando-se em documentação produzida pelo Departamento de Estado e pela Agência de Informação dos Estados Unidos (USIA), o presente artigo tem por objetivo tratar da ação ideológica da Aliança para o Progresso. O foco da reflexão apresentada se centra na análise da política editorial implementada ao longo dos anos 1960, que buscava influenciar os debates sobre desenvolvimentismo travados no Brasil e na América Latina e, assim, promover a defesa de um capitalismo adequado à hegemonia estadunidense. A análise demonstra que, apesar de inovadora e ambiciosa como política externa hemisférica, a implementação da Aliança foi permeada por continuidades ideológicas e preocupações geopolíticas tradicionais do relacionamento dos Estados Unidos com a região latino-americana.

Authors: Wilk Renata , Kluczewska Ewa , Likus Wirginia 
Published: October 2019

PurposeThe aim of the study was to develop the normative values of linear indices to the diagnosis of changes in size of the subarachnoid space.Material and methodsRetrospective studies were conducted based on 507 head computed tomography (CT) exa­minations in children from 0-18 years of age. In total 381 tests were selected for correct reference values. Patients were divided into age groups. For each group, linear indices were calculated, taking into account the size of the fluid spaces in relation to the size of the skull and then the mean with standard deviation, median, as well as 10th and 90th percentile were calculated. The range between the 10th and the 90th percentiles was defined as the reference value.ResultsObtained normative values, minimum and maximum for all groups: index of basal cistern size to the size of the skull – 0.129-0.197; index of basal cistern transverse dimension to the size of the skull – 0.173-0.255; index of basal cistern sagittal dimension to the size of the skull – 0.086-0.150; index of prepontine cistern – 0.034-0.067; index of interhemispheric fissure width – 0.044-0.127; index of Sylvian fissure – 0.036-0.085; index of insular cistern width – 0.020-0.074; index of subarachnoid space – 0.017-0.081.ConclusionsThe linear indices can be calculated based on images achieved during routine CT examination. The reference values allow us to determine if the size of the subarachnoid space is within the normal range for a given age group. The results from the oldest age group can also be referred to the adults.

Published: October 2019

PurposeTraumatic vertebral artery injury (TVAI) can have a varied clinical presentation and appearance on imaging.
In this review, we present the screening criteria, spectrum of imaging features, grading, and imaging pitfalls of TVAI. Our review focuses on the imaging of TVAI on computed tomography angiography (CTA), magnetic resonance angio­graphy (MRA), and cases of TVAI mimics.ImagingThe imaging spectrum on CTA can range from either focal or long segment luminal stenosis (the most common findings), smooth or tapered narrowing of lumen, string of pearls appearance, concentric intramural haematoma, intimal flap (the most definite sign), and double lumen of the artery. On time-of-flight MRA, the most common findings include loss of flow void within the vessel due to slow flow, thrombosis or occlusion, and hyperintense signal within the vessel wall due to intramural haematoma on T1 fat-saturated images.ConclusionThe reader should be aware of the screening criteria, common and uncommon findings, variant anatomy, artefacts, and mimics of TVAI when evaluating cases of craniocervical trauma, to be competent in calling in or ruling out injury.

Published: October 2019

PurposeThe purpose of this study was to assess the suitability of susceptibility-weighted imaging (SWI) sequences using the 3T MRI-unit for assessment of potential intraarticular pathologies in patients with acute and chronic torsion trauma of the knee joint.Material and methodsSixty-three patients with subacute and chronic rotary knee joint trauma of either the left or right knee were studied using an Achieva MRI 3T device (Philips, Amsterdam, Netherlands). Ground truth was set by two expert radiologists with seven and 10 years of experience in musculoskeletal imaging. Readings were performed separately for meniscus and joint space including synovia, ligaments, and periarticular soft tissue. Haemorrhage was defined as any lesion that was either T1 or SWI positive, without proton density (PD)-hypointensity (calcification). A lesion was defined as any pathology/variant with any signal positivity of either T1, PD, or SWI.ResultsA total of 63 patients were included (F : M = 22 : 41). The median age of the cohort was 29 years (range 13 to 71 years). Thirty-nine patients showed a meniscal tear, and only three of them (7.7%) demonstrated a meniscal haemorrhage. A total of 18 patients suffered from a periarticular injury, and 16 patients (88.9%) demonstrated a concomitant periarticular haemorrhage.ConclusionsThese data suggest that SWI can be used for the diagnosis of intra- or periarticular blood metabolites because their potential have an impact on mechanical conflict with the surface of the knee joints, in particular the cartilage and their effect on malacic lesions, but it performs poorly in the detection of meniscal pathologies.
