Authors: Nguyen-Huy Dung 
Published: June 2019

Le tétrafluoroséléniure de cérium Ce₂SeF₄ est rhomboédrique, de groupe spatial R[-3]m. La maille hexagonale triple, de paramètres ah = 4,144 Å, ch = 23,09 Å contient trois masses formulaires.
La structure cristalline a été établie sur un monocristal et les positions des atomes ont été affinées par la méthode des moindres carrés, avec un facteur d'incertitude R égal à 0,045.
Cette structure peut être considérée comme formée d'une alternance de couches d'anions sélénium et de couches de groupements Ce₂F₄ dans lesquels les anions fluor forment un empilement rhomboédrique compact à quatre couches.

Hasil belajar peserta didik merupakan salah satu indikator dalam keberhasilan pendidikan, hasil belajar peserta didik merupakan nilai ahir dari pencapaian peseta didik dalam memehami materi yang disampaikan pada saat belajar mengajar. Banyak sekali faktor yang dapat berpengaruh pada tinggi rendahnya nilai hasil belajar peserta didik dan salah satunya adalah metode yang digunakan dalam proses pembelajaran. Dalam upaya meningkatkan hasil belajar peserta didik dapat diberikan metode hipnotiching kepada peserta didik dan dapat diberikan pula kepada anak sekolah dasar. Pada dasarnya mengajarkan dengan beberapa metode pada anak SD itu sangat dianjurkan dimana anak pada usia ini masih tergolong masa kanak-kanak yang karakteristiknya cepat bosan sehingga metode yang diberikan harus menarik bagi anak. Metode hipnotiching ini sangat bagus untuk diberikan kepada anak SD dimana metode-metode lama membosankan dan metode ini cukup merangsang konsentrasi bagi anak, dengan menggunakan metode ini diharapkan ada perkembangan yang baik dalam proses belajar sehingga mencapai hasil yang optimal.

Abstract
Protoplanetary disks orbiting intermediate-mass stars, Herbig Ae/Be stars, that have formed in a metal-poor environment may evolve differently than their Galactic cousins. A study of the planet-formation process in such an environment requires identification and characterization of a sample of candidates. We have observed several stars in the Small Magellanic Cloud, a nearby metal-poor dwarf galaxy, that have optical spectral properties of Herbig Ae/Be stars, including strong Hα emission, blue continuum excess, and spectral types ranging from early G to B. Infrared spectra of these sources from the Spitzer Space Telescope show strong excess emission indicating the presence of silicate dust, molecular and atomic gas, and polycyclic aromatic hydrocarbons. We present an analysis of the likelihood that these candidates are Herbig Ae/Be stars. This identification is the necessary first step to future investigations that will examine the role of metallicity in the evolution of protoplanetary disks.
ALMA Observations of a Massive and Dense Cold Clump: G305.137+0.069
Authors: Servajean Elise , Garay Guido , Rathborne Jill , Contreras Yanett , Gomez Laura 
Published: June 2019

Abstract
We report observations, made with the Atacama Large Millimeter/submillimeter Array, of 3 mm dust continuum emission and molecular line emission in HCO+, CS, and N2H+, toward G305.137+0.069, a massive, dense, and cold clump, in order to characterize its small-scale (∼2000 au) structure. The dust continuum observations reveal the presence of twelve compact structures (cores) with masses ranging from 3.3 to 50.6 M
⊙, radii from 1800 to 5300 au, and densities from 3.1 × 106 to 3.1 × 107 cm−3. The line observations show that the molecular emission arises from a bright central region, with an angular size of ∼12″, and an extended, weaker envelope best seen in the HCO+ line. The N2H+ emission is best correlated with the continuum emission and hence with the cores. For cores with single line profiles, the line widths range from 1.9 to 3.1 km s−1 with an average value of 2.6 km s−1, indicating that they are dominated by nonthermal motions, either due to random turbulence or core-scale motions. The virial parameter of the three most massive cores are smaller than one, suggesting that they are undergoing collapse. We find that in the regime of masses probed by our observations (M > 3 M
⊙) the shape of the core-mass function is notably different from the initial mass function, showing an overpopulation of high-mass cores. We suggest that the formation and mass distribution of the dense cores within G305.137+0.069 can be explained as the result of hierarchical or turbulent fragmentation in a gravitationally collapsing clump.
The Correlated Variations of Absorption Lines and Quasar Continuum

Published: June 2019

Abstract
Using the quasar spectra from the Sloan Digital Sky Survey and with variable C iv absorption line systems, we measure the Si iv and N v absorption line systems. We obtain 50 variable Si iv absorption line systems and 39 variable N v absorption line systems. We find that the variations in most of the C iv, Si iv, and N v absorption lines are correlated with the changes in quasar continuum. In addition, a significant portion of the variable absorption lines are the consistent variations of multiple systems with large velocity separations. Therefore, the variations of the C iv, Si iv, and N v absorption lines could be mainly driven by the changes in quasar radiations, which cause changes in ionization states or column densities of absorbing gas. We also find that the variable C iv, Si iv, and N v absorption line systems can be divided into low-ionization systems and high-ionization systems. The former positively responds to the changes in the quasar’s brightness, and the later is the oppositive case.
Association of Retinal Inner Layer Disorganization With Ultra-Widefield Fluorescein Angiographic Features and Visual Acuity in Branch Retinal Vein Occlusion
Authors: Yu Jeannette J. , Thomas Akshay S. , Berry Duncan , Yoon Stephen , Fekrat Sharon , Grewal Dilraj S. 
Published: June 2019

BACKGROUND AND OBJECTIVE:
To assess the impact of the disorganization of retinal inner layers (DRIL) on visual acuity (VA) and its correlation with ischemic index (IsI) on ultra-widefield fluorescein angiography (UWFFA) in eyes with acute, treatment-naïve branch retinal vein occlusion (BRVO).

PATIENTS AND METHODS:
Retrospective, longitudinal study of BRVO eyes with 1 year of follow-up or more. Area of intraretinal cysts, DRIL length, extent of disruption of external limiting membrane (ELM), and ellipsoid zone (EZ) were graded on the central 1,000 μm of foveal optical coherence tomography (OCT) scan. Baseline IsI was calculated on UWFFA.

RESULTS:

Thirty eyes of 30 patients with a mean follow-up of 25.4 months ± 11.0 months were evaluated. At baseline, 50% had DRIL (mean 443.1 μm ± 460.4 μm). DRIL length at baseline was predictive of worse VA at 12 months (
P
= .029), and DRIL length at 12 months was predictive of worse final VA(
P
= .011). In multivariate analyses, DRIL length was associated with final VA (
P
= .008) after controlling for other OCT parameters. There was no association between baseline IsI on UWFFA and DRIL.

CONCLUSIONS:
DRIL served as an independent OCT biomarker predictive of worse VA during a period of 2 years in acute, treatment-naïve BRVO. Development of DRIL was influenced by presence of CME, intraretinal cyst area, and extent of ELM and EZ disruption, but not by severity of baseline IsI.

Published: June 2019

BACKGROUND AND OBJECTIVE:
To investigate clinical features and surgical outcomes of vitrectomy in posterior or combined persistent fetal vasculature (PFV) in an Asian pediatric population.

PATIENTS AND METHODS:
This study was a retrospective, noncomparative, interventional case series relating the surgical outcome of PFV. Eyes that underwent pars plicata vitrectomy and/or lensectomy for posterior or combined PFV between 2006 and 2015 were included. The main outcome measures were the anatomic and functional results as well as the complications after the vitrectomy with or without lensectomy.

RESULTS:

A total of 25 eyes of 18 patients younger than 8 years of age were included in the study. The mean age of the patients receiving first pars plicata vitrectomy and/or lensectomy was 15.2 months ± 21.7 months (range: 1 month to 83 months). Postoperatively, successful anatomic correction in the posterior segment was observed in 20 eyes (80%). In addition, 19 of the 25 eyes (76%) had visual acuity (VA) better than 20/4000, and the mean logMAR VA of these 19 eyes was 1.74 (range: 0.48 to 2.30). The mean change of axial length of the eyes receiving surgery was 0.7 mm ± 1.4 mm (range: −1.0 mm to 2.4 mm;
P
= .18). None of the patients ended up with phthisis or glaucoma.

CONCLUSIONS:
This study suggests that vitrectomy and/or lensectomy in patients with posterior or combined PFV with macular involvement may result in an acceptable anatomical outcome; however, the functional outcome remained poor despite surgical intervention in these patients.

Livros de leitura e a construção da identidade nacional de crianças italianas e descendentes (São Paulo no início do século XX)
Authors: Panizzolo Claudia 
Published: June 2019

A partir do último quartel do século XIX o imigrante estrangeiro passou a desempenhar um papel cada vez mais relevante na história de São Paulo. O presente texto tem por objetivo investigar as operações de civilidade impressas e impostas nos livros de leitura que alcançaram circulação expressiva nas escolas étnicas italianas e nas escolas primárias paulistas frequentadas pelos imigrantes e/ou seus filhos, entre o final do século XIX e o início do século XX. A partir da perspectiva teórico-metodológica da história cultural toma-se como fonte privilegiada a ‘Série graduada de Puiggari-Barreto’ e o livro de leitura Piccolo mondo. Com base no corpus conceitual constituído por Norbert Elias, os procedimentos, os instrumentos, as fontes e as direções de análise foram definidas, uma vez que interessa examinar práticas e processos de modelação dos sujeitos crianças que viviam o tempo social da infância, pelos quais se constituem como configurações mentais ou psíquicas, e nos quais cognição, sentimento, atitude, comportamento, valor, não são passíveis de abstração. Os autores expressaram em seus livros um projeto civilizatório, em que a formação do cidadão, o amor à pátria, o reconhecimento e a valorização dos heróis, dos valores, da língua, dos grandes feitos, dos monumentos e das paisagens ganharam proeminência. Os autores reivindicaram em seus livros de leitura, produzidos nos dois lados do oceano Atlântico as marcas de uma identidade nacional almejada.
Hepatitis B and HIV co-infection in South Africa: Just treat it!
Authors: Firnhaber Cynthia S , Ive Prue 
Published: June 2019

There are an estimated 350 million hepatitis B carriers worldwide. The prevalence of mono-infection with hepatitis B in South Africa has been estimated at approximately 10% for the rural population and 1% in urban areas. The transmission routes of hepatitis B and HIV are similar, but hepatitis B is more efficient. Co-infection with HIV and hepatitis B is therefore not unusual. Recent studies have shown that the prevalence of HIV/HBV co-infection (using HBV surface antigen (HBsAg) as a marker for HBV) in South Africa ranges from 4.8% to 17%, depending on the population studied.The guidelines for the South African HIV Comprehensive Care, Management and Treatment (CCMT) programme do not include viral hepatitis studies. Hepatitis B serology is usually done only if serum aminotransferases are evaluated in the absence of another known cause (e.g. tuberculosis and concomitant medications). The clinical sequelae of HIV/HBV co-infection are multiple and can cause an increase in morbidity and mortality. Awareness of HBV/HIV co-infection with appropriate diagnosis and management is imperative for improved care of our HIV patients.
