Ferro's El otro Joyce: Originals and Copies
Authors: Peña Kathleen
Published: February 2018

This article explores Roberto Ferro’s novel El otro Joyce (2011), a work of translational literature that straddles two languages and two literary traditions. Its protagonist, Jorge Cáceres, runs a small business researching patents, missing books, and missing persons. The novel’s plot follows him as he works to solve two mysteries: one related to the search for a first edition of Joyce’s Finnegans Wake, annotated by Jorge Luis Borges, and the second related to the suspicious death of Marcos Almeida, a prominent financier. Much like Finnegans Wake, El otro Joyce is a highly self-conscious narrative teeming with digressions and literary allusions. Cáceres’s work is constantly hindered and confused by the appearance of doubles, a theme that relates to the act of translation and also to betrayal, present throughout the novel. Part detective narrative and part historical metafiction, Ferro’s novel is a reflection on the continuing role of Joyce in the Argentine literary tradition—a tradition inseparable from the act of translation.
Intervenciones contaminantes y profilaxis cinemática en la vecindad de Pepe El Toro: la trilogía del mexicano Ismael Rodríguez (1948-1953)
Authors: Juliana Rocha Dallos Silvia
Published: February 2018

Uno de los retos del director mexicano Ismael Rodríguez es yuxtaponer una estética escenográfica que dé cuenta de las tribulaciones resultantes de la vida en el medio urbano, junto a un discurso de benevolencia, capaz de subrayar los problemas que, en materia de salud pública, simbolizaban los sectores marginados. Largometrajes como Nosotros los pobres (1948), Ustedes los ricos (1948) y Pepe El Toro (1953), ofrecen una entrada al tema de la higiene en sus sentidos médico, pedagógico y arquitectónico de principios del siglo XX en la Ciudad de México. Por un lado, marcan la separación de sujetos y grupos ajenos a la estética oficial en el diseño urbano, enfatizando la representación de locaciones como la vecindad, el hospital o la cárcel; y por otro, demuestran un vínculo entre el discurso de la higiene de los edificios y la de los cuerpos, insistiendo en escenas que indican un proceso de profilaxis (cinemática), en el cual se previene al espectador sobre los riesgos que algunos sujetos pueden acarrear a la sociedad. En la trilogía estudiada, se destacan personajes que representan a mujeres alcohólicas, ladrones, enfermos de tuberculosis, prostitutas, así como campesinos que emigraron a los Estados Unidos, por motivo del programa Bracero (1942-1964). Las estrategias visuales empleadas por Rodríguez —los encuadres a la tisis, el acto de lavar y reconstruir la vecindad, la dislocación discursiva del Bracero, y los close-up a rostros desaliñados— trazan una radiografía melodramática y problemática del nacionalismo mexicano.
,“A Collision of Disparate Historical Timescales in Ignácio de Loyola Brandão’s And Still the Earth.”
Authors: Gouveia Saulo
Published: February 2018

This essay offers an eco-critical reading of Ignacio de Loyola Brandão 's 1981 novel Não verás país nenhum. (Trans. And Still the Earth, 1985). I examine in detail the novel's unconventional and multi-layered conceptualizations of history while also focusing on aesthetic aspects of Brandão’s depiction of social, political, and environmental degradation. My analysis expands on the contextual timeframe of the Military Dictatorship years (1964-1985) with which the novel is conventionally associated. I propose instead to approach Brandão’s text through wider historical and spatial perspectives. I show how the novel articulates unconventional conceptualizations of history that challenge long-standing humanistic approaches. Though closely related to specific historical and political contexts in Brazil, this decades-old narrative anticipated many of the anxieties that became part of current global debates on the Anthropocene and its impact on humanistic precepts in the Humanities and in the Social Sciences.

Experimental study on solidification of Cu(II)-contaminated soil using red mud with cement and Ca(OH)2
Authors: Song Zhiwei , Suo Chongxian , Dong Xiaoqiang , Chen Y. Frank
Published: February 2018

Red mud is a waste product generated by the aluminum industry and its presence has significantly damaged the environment. Interestingly, red mud has some desirable adsorptive properties and can solidify heavy metal ions. Moreover, after processing, red mud has certain cementing properties that have a positive influence on the curing effect of red mud cement-treated soil. This study examined different ratios of red mud, cement and Ca(OH)2 by testing the electrical resistivity and unconfined compressive strength of various soils. The resistivity test indicates that the electrical current frequency has a great influence on the test results. It is recommended that a current frequency between 1 and 50 kHz is used in a resistivity test. The study also indicates that, with increasing Cu2+ content, conductive tunnel effect occurs. However, when the ratio of curing agent and content of Cu2+ are different, the time causing the conductive tunnel effect varies. The unconfined compressive strength of different cement-to-soil ratios decreases with increasing Cu2+ content and the reduction extent is related to that ratio. Lastly, the study results suggest a good linear relationship between unconfined compressive strength and electrical resistivity, which is dependent on the specific ratio of contaminating materials.

Published: February 2018

Purpose: The Guelph Family Health Study (GFHS) pilot was designed to examine the feasibility and effectiveness of a home-based obesity prevention intervention on health behaviours and obesity risk. The objective of this analysis was to determine the effect of the 6-month intervention on preschool-aged children’s dietary intakes.

Methods: Families with children aged 1.5–5 years old were randomized to receive one of the following: 4 home visits with a health educator as well as tailored emails and mailed incentives (4HV; n = 19 children); 2 home visits with a health educator as well as tailored emails and mailed incentives (2HV; n = 14 children); or general health advice through emails (control; n = 12 children). Three-day food records were completed by parents for their children before and after the 6-month intervention and analyzed for 3-day average intakes of energy, nutrients, and MyPlate food groups.

Results: After the 6-month intervention, the 4HV group had significantly higher fibre intake and the 4HV and 2HV groups had significantly higher fruit intake, both compared with the control group.

Conclusions: This study provides support for a home-based intervention approach to improve the diet quality of preschool-aged children.
Synthesis of Cholestan -3-One Derivatives Possessing a C-2 Spiro-Oxindole Substituent
Authors: Tao Hongwen , Yuan Yinan , Chen Jian , Yu Xianyong , Yi Pinggui
Published: February 2018

A series of C-2 cholestan-3-one spiro-oxindole derivatives were prepared by the 1:3 dipolar cycloaddition reaction between the cholestan-3-one substituted by a C-2 arylidene and the azomethine ylid derived from isatin and sarcosine. The dipolarophiles were efficiently obtained by a Claisen-Schmidt reaction of cholestan-3-one and aromatic aldehydes. The structures of the products were established by a combination of NMR, high-resolution mass spectrometry (HRMS) and X-ray data analysis.
Synthesis of 3-Aryl-1-Indanones via CsF-Promoted Coupling of Arylboronic Acids with N-Tosylhydrazones

Published: February 2018

In the paper, use of stylus profilometry technique in measurements of surface roughness parameters of technological equipment used in the food industry has been demonstrated. The assessment of internal surfaces of the vertical conical mixing unit and its components was carried out by the use of stylus instrument Hommel-Tester T-8000 supported bythe HommelMap Basic 3.1 software. The obtained values of selected roughness (profile) parameters (Ra, Rq, Rp, Rv and Rz) as well as results of the others carried out analysis (Abbott-Firestone curves, graphical studies of Sk parameters) confirmed the correctness of machining process of the assessed surfaces, despite fact, that measurement process were complicated dueto their large size and weight.
INFLUENCE OF MATERIAL HARDNESS AND PARTICLE VELOCITY ON EROSIVE WEAR RATE
Authors: Kosa Ergin , Göksenli Ali
Published: February 2018

Many parameters such as medium conditions and material properties are effective on erosiveabrasive wear rate. In this study, effect of particle impact velocity and hardness of material on wear rate and wear mechanism was investigated. All tests were carried out in 20% sand-water mixture. Impact velocities of the particles were ranking between 2.04 m/s and 4.76 m/s. Hardness values of St 37 and Ck 45 steels were changed by applying different heat treatments. After wear tests it was concluded that by an increase of impact velocity and decrease of material hardness, wear rate increased. This increase was by soft materials more dominant than by hard materials. After morphological investigations it is concludedthat by an increase of material hardness, number and size of craters on the surface after erosion tests decreased. By using experimental test results, a new mathematical formulation was developed to emphasize the relation between impact velocity and material hardness on wear rate.

Published: February 2018

This study presents an approach to intelligent fault prediction based on time-domain and frequency-domain (FFT phase angle and PSD) statistical analysis, Principal component analysis (PCA) and adaptive Neuro-fuzzy inference system (ANFIS). After vibration data acquisition, the approach consists of three stages is conducted. First, different features, including time-domain statistical characteristics, and frequency-domain statistical characteristics are extracted to get more fault detection information. Second, three components by a principal component analysis are obtained from the original feature set. Finally, these three components are inputted into ANFIS for a development model of identifying different abnormal cases. The proposed approach is applied to fault diagnosis of gearbox's number one gear of MF285 tractor, and the testing results show that the proposed model can reliably predict different fault categories and severities.

Published: February 2018

Low serum vitamin D levels have been associated with various vascular diseases. Very little is known its association with acute stroke in Bangladeshi population. We therefore sought to assess whether low serum 25- hydroxyvitamin D, a marker of vitamin D status is associated with acute stroke. We performed a prospective study in Comilla Medical Collage, Comilla, from November 2016 to November 2017. All the patients diagnosed as acute ischemic stroke on the basis of CT scan or MRI of brain. Patients were eligible for inclusion if they were admitted with onset of symptoms within 24 hours. Estimation of 25(OH)D level was done at presentation. The patients were stratified by vitamin D status, >30 as vitamin D sufficient, vitamin D 20-20.9 as insufficient and finally vitamin D<20 as deficient. Multivariate logistic regression analysis revealed that out of the desired 7 variables, smoking, hypertension and low serum vitamin D were found independent predictors for acute stroke with ORs being 1.44, 4.23 and 2.39 respectively. Vitamin D deficiency represents an important risk factor for acute stroke and it might play a causal role in the development adverse events associated with stroke.Medicine Today 2018 Vol.30(1): 34-37

L'Age du fer dans la dépression permienne, et dans les massifs des Maures et de l'Estérel (Var)
Authors: Bérato Jacques , Borréani Marc , Gébara Chérine , Michel Jean-Marie
Published: February 2018

The geographic area of the Permian depression, the Massif des Maures and the Estérel is heterogeneous. During the Iron Age human implantation basically corresponds to local circumstances. The fortified hill-top habitat remains the principal dwelling place and is no longer occupied after the years 30/20 B. C. It has never been possible to study the internal arrangement of this habitat exhaustively. Non-fortified hill-top habitats are rare. The settlements in the plain, at the foot of a hill, on the slope or on the plateau are always open and exist during practically the entire Iron Age. Those in the plain develop particularly during the Ist century B.C. in the shape of hamlets, when the hill-top habitats are abandoned. Caves are not much used. There are few indigenous places of worship and few cremation tombs. During the entire Iron Age the region studied presents a cultural continuity, an undeniable archaism and a tendency to marginalization.
Vestiges d'un tumulus du premier Age du fer sur la crête de l'Arboussède (Cannes-et-Clairan, Gard)
Authors: Dedet Bernard
Published: February 2018

A much eroded barrow situated on the hill of the Arboussède yielded pottery from the beginning of the Early Iron Age. This discovery is of three-fold interest : it is a small closed unit ; it serves to classify the pottery of the Garrigues de Vidourlenque, in Eastern Languedoc : it makes a link between the tumuli of the Garrigues of the Hérault department and those of the Malgoirès in the Gard department. Concerning the field of funerary archaeology, however, these remains leave many questions open.

La fouille d'une cavité karstique (aven), creusée dans les plateaux de Vaucluse, a permis de découvrir de nombreux vestiges (essentiellement céramiques) de la fin du Néolithique et surtout de l'Age du bronze final (BF 1 et BF 2). L'approche typo-chronologique et spatiale du mobilier permet, malgré l'absence d'une véritable stratigraphie, de mettre en évidence la pluralité des fonctions de cet aven. L'analyse du mobilier apporte quant à elle une contribution non négligeable à la connaissance de la Protohistoire ancienne vauclusienne, mal connue dans ce département.

Depuis la découverte fortuite en 1992 de deux cavités au lieu-dit le Mourre de la Barque à Jouques, des fouilles se déroulent dans la cavité la plus occidentale ayant révélé la présence d'un fort remplissage archéologique protohistorique (Age du fer et Age du bronze) et préhistorique (Néolithique). Une première description de la séquence protohistorique, réalisée à partir de l'analyse du mobilier archéologique, est proposée. Ont été reconnus des niveaux se rapportant au premier Age du fer, au Bronze final IIIb, au Bronze moyen évolué ainsi qu'au Bronze ancien. Cette étude est complétée par une analyse paléoéconomique et un essai de reconstitution paléoenvironnementale qui apportent, à travers une approche pluridisciplinaire, quelques éléments supplémentaires à une documentation encore lacunaire pour cette période.

Published: February 2018

Les fouilles de F. Benoit ont mis au jour une quinzaine de blocs provenant de pressoirs et au moins deux installations de pressurage en place. Celle de l'îlot III, totalement fouillée, fait l'objet d'une publication complète y compris de la totalité du mobilier qui est décrit et dessiné dans le CD-Rom. A partir de cet exemple bien conservé et de l'inventaire de tous les blocs anciennement découverts sur le site (tous les blocs sont décrits, photographiés et dessinés dans le CD-Rom), on tente de déterminer la nature de la production, essentiellement l'huile d'olive. Un recensement des pressoirs préromains de Gaule Transalpine permet d'élargir le champ d'observation à l'ensemble de la Provence et du Languedoc et de conclure à un développement net mais géographiquement limité de l'oléiculture au IIe s. et au début du Ier s. av. J.-C.
Les objets de la vie quotidienne à Entremont chez Fernand Benoit et aujourd'hui
Authors: Willaume Martine
Published: February 2018

Le colloque, organisé à la mémoire de Fernand Benoit pour le cinquantième anniversaire des fouilles d'Entremont, offre l'opportunité d'observer le rôle qu'ont joué les objets de l'artisanat et de la vie quotidienne dans la pensée et l'œuvre de Fernand Benoit. Sa compréhension du développement urbanistique de la ville s'appuie sur la présence des structures artisanales, des objets et des outils qui le pousse à définir, parfois avec réticence, une différence fonctionnelle et sociale entre les deux parties de la ville. Avec l'exemple du fer, on compare ici les apports quantitatifs et qualitatifs des fouilles anciennes et récentes. Une étude de répartition permet de battre en brèche une répartition fonctionnelle trop stricte entre les deux quartiers de la ville. L'occasion est aussi offerte de poursuivre la discussion sur l'identification de la pièce 2 de l'îlot 29, en tant que sanctuaire primitif ou dépotoir domestique et artisanal. L'auteur plaide pour cette dernière interprétation en reprenant dans le détail les indices, parfois inédits, pouvant fonder l'analyse. Enfin, cet anniversaire incite à faire le point des travaux qu'il reste à engager dans ce domaine.
Nouvelles recherches sur le "sanctuaire" de Roquepertuse à Velaux (IIIe s. av. J.-C.). Premiers résultats
Authors: Boissinot Philippe , Lescure Brigitte
Published: February 2018

Recent research on the Roquepertuse " shrine " at Velaux (IIIrd century BC). The first results.

The recent excavations undertaken at the Roquepertuse site have allowed us to estimate the extent of the agglomeration that the developed along the valley and on the hillside at the foot of the oppidum itself. The extensive stripping of the remnants still in situ on terrace 1 -the supposed "shrine" -brought to light the locality of the famous portico, and revealed the massive fortification that dominates the area behind. Finally, the reexamination of the lapidary collections in the light of the evidence from the field and recent discoveries allows us to propose new hypotheses regarding their dating, their situation, and their style.
L'habitat fortifié du Mitronet (Puyloubier, B.-du-Rh.). Un site protohistorique isolé sur le massif Sainte-Victoire
Authors: Mocci Florence , Marty Frédéric , Walsh Kevin
Published: February 2018

Une étude récente sur le petit habitat perché du Mitronet situé à l'extrémité orientale du bassin d'Aix-en-Provence, sur le piémont de Puyloubier, apporte de nouveaux éléments de réflexion sur l'occupation du sol du massif Sainte-Victoire au cours du deuxième âge du Fer. De par sa localisation et par son double système défensif, le site du Mitronet s'apparente à un petit habitat agro-pastoral fortifié dont la fonction sociale et économique devait être relativement importante pour qu'il ait fait l'objet d'aménagements complexes. Durant les deux phases d'occupation reconnues, du milieu du IIIe s. au premier quart du IIe s. av. n. è., ce site apparaît paradoxalement bien isolé sur le versant méridional de la montagne. La présence de cette communauté fonctionnant en relative autarcie prend ainsi une signification toute particulière sur ce massif.
Randomized Controlled Trial Comparing Open versus Laparoscopic Placement of a Peritoneal Dialysis Catheter and Outcomes: The Capd I Trial
Authors: van Laanen Jorinde H.H. , Cornelis Tom , Mees Barend M. , Litjens Elisabeth J. , van Loon Magda M. , Tordoir Jan H.M. , Peppelenbosch Arnoud G.
Published: February 2018

Objective

To determine the best operation technique, open versus laparoscopic, for insertion of a peritoneal dialysis (PD) catheter with regard to clinical success. Clinical success was defined as an adequate function of the catheter 2 – 4 weeks after insertion.

Methods

All patients with end-stage renal disease who were suitable for PD and gave informed consent were randomized for either open surgery or laparoscopic surgery. A previous laparotomy was not considered an exclusion criterion. Laparoscopic placement had the advantage of pre-peritoneal tunneling, the possibility for adhesiolysis, and placement of the catheter under direct vision. Catheter fixation techniques, omentopexy, or other adjunct procedures were not performed. Other measured parameters were in-hospital morbidity and mortality and post-operative infections.

Results

Between 2010 and 2016, 95 patients were randomized to this study protocol. After exclusion of 5 patients for various reasons, 44 patients received an open procedure and 46 patients a laparoscopic procedure. Gender, age, body mass index (BMI), hypertension, current hemodialysis, severe heart failure, and previous an abdominal operation were not significantly different between the groups. However, in the open surgery group, fewer patients had a previous median laparotomy compared with the laparoscopic group (6 vs 16 patients; p = 0.027). There was no statistically significant difference in mean operation time (36 ± 24 vs 38 ± 15 minutes) and hospital stay (2.1 ± 2.7 vs 3.1 ± 7.3 days) between the groups. In the open surgery group 77% of the patients had an adequate functioning catheter 2 – 4 weeks after insertion compared with 70% of patients in the laparoscopic group ( p = not significant [NS]). In the open surgery group there was 1 post- operative death (2%) compared with none in the laparoscopic group ( p = NS). The morbidity in both groups was low and not significantly different. In the open surgery group, 2 patients had an exit-site infection and 1 patient had a paramedian wound infection. In the laparoscopic group, 1 patient had a transient cardiac event, 1 patient had intraabdominal bleeding requiring reoperation, and 1 patient had fluid leakage that could be managed conservatively. The survival curve demonstrated a good long-term function of PD.

Conclusion

This randomized controlled trial (RCT) comparing open vs laparoscopic placement of PD catheters demonstrates equal clinical success rates between the 2 techniques. Advanced laparoscopic techniques such as catheter fixation techniques and omentopexy might further improve clinical outcome.
Single Daily Icodextrin Exchange as Initial and Solitary Therapy
Authors: Agar Baris U. , Sloand James A.
Published: February 2018

Background

Incremental dialysis utilizes gradually increasing dialysis doses in response to declines in residual kidney function, and it is the preferred renal replacement therapy for patients who have just transitioned to end-stage renal disease (ESRD). Incremental peritoneal dialysis (PD) may impose fewer restrictions on patients’ lifestyle, help attenuate lifetime peritoneal and systemic exposure to glucose and its degradation products, and minimize connections that could compromise the sterile fluid path. In this study, we utilized a 3-pore kinetic model to assess fluid and solute removal during single daily icodextrin treatments for patients with varying glomerular filtration rates (GFR).

Methods

Single icodextrin exchanges of 8 to 16 hours using 2- and 2.5-L bag volumes were simulated for different patient transport types (i.e., high to low) to predict daily peritoneal ultrafiltration (UF), daily peritoneal sodium removal, and weekly total (peritoneal + residual kidney) Kt/V (Kt/VTotal) for patients with residual renal GFRs ranging from 0 to 15 mL/min/1.73 m2.

Results

Daily peritoneal UF varied from 359 to 607 mL, and daily peritoneal Na removal varied from 52 to 87 mEq depending on length of icodextrin exchange and bag volume. Both were effectively independent of patient transport type. All but very large patients (total body water [TBW] > 60 L) were predicted to achieve adequate dialysis (Kt/VTot al ≥ 1.7) with a GFR of 10 mL/min/1.73 m2, and small patients (TBW: 30 L) were predicted to achieve adequate dialysis with a GFR of 6 mL/min/1.73 m2.

Conclusions

A single daily icodextrin exchange can be tailored to augment urea, UF, and Na removal in patients with sufficient residual kidney function (RKF). A solitary icodextrin exchange may therefore be reasonable initial therapy for some incident ESRD patients.

Background

Long-term peritoneal dialysis (PD) is frequently complicated by technique failure preceded by peritoneal remodeling. Vitamin D has potent immunomodulatory characteristics: anti-inflammatory, anti-angiogenic, anti-fibrotic properties, and influences on the macrophage phenotype. Little is known about the relation between pleiotropic effects attributed to vitamin D3 and the peritoneal membrane and what is the most appropriate vitamin D sterol in prevention of peritoneal remodeling in PD patients. Animal studies have suggested that paricalcitol has advantageous effects: decrease in plasma markers of inflammation, less peritoneal fibrosis, less pronounced PD-induced omental angiogenesis, and prevention of loss of ultrafiltration. We investigated whether paricalcitol is advantageous over calcitriol in PD patients.

Method

A multicenter open-label 1:1 randomized non-blinded clinical pilot study enrolled prevalent continous ambulatory PD (CAPD) patients for a period of 6 months comparing paricalcitol with calcitriol. All patients were treated with biocompatible PD fluids. The primary endpoint was peritoneal transport parameters, exploratory endpoints were biomarkers of peritoneal damage and cell analysis (including M1/M2 macrophages), and safety endpoints were metabolic parameters.

Results

Twenty-seven patients were included. Fourteen were randomized to treatment with paricalcitol. There was no difference in peritoneal transport parameters between the groups. We found similar Kt/V, D/P creatinine, D/D0 glucose, ultrafiltration, residual renal function and 24-h urine volume during the study. There was no difference in biomarker concentrations in peritoneal effluents, and no difference in leucocyte differentiation or mesothelial cells between the groups at any time point. Parathyroid hormone (PTH) levels decreased after administration of calcitriol after 12 and 24 weeks compared with baseline ( p = 0.001; p = 0.025). Parathyroid hormone levels in the paricalcitol group did not change significantly.

Conclusion

In this pilot study we investigated the effect of active vitamin D in PD patients. We found no specific benefit of active vitamin D3 in vitamin D3-sufficient PD patients. Additional studies in preferably incident patients, with an adequate PTH suppression in the intervention groups and during a longer period, are required to test the beneficial effects of active vitamin D3 over no treatment and to investigate whether in 25(OH)D3-deficient PD patients the type of active vitamin D3 matters.

Authors: Petrescu Emil , Cirtoaje Cristina , Danila Octavian
Published: February 2018

The dynamic behavior of a mixture consisting of liquid crystalline 4-cyano-4’-pentylbiphenyl (5CB) and CdSe/ZnS quantum dots in electric fields was theoretically studied. The model was based on elastic continuum theory considering the interaction of the nematic molecules with the surrounding molecules, with the quantum dots and with the electric field. Experimental data obtained by dynamic measurements on a sample containing 0.89% (mass fraction) of CdSe/ZnS quantum dots revealed a decrease of the relaxation time compared to pure 5CB.

The Effect of Shadow Economy – Country'S Tax Losses
Authors: Krumplytė Jolita
Published: February 2018

The article analyzes the content of shadow economy through the prism of the tax administration. The author provides the limitations of the study and methodologically based relationship between the shadow economy and the tax revenue not to be received to the national consolidate budget. Country’s tax losses (tax gap) is the amount of the tax revenue that is not received to the country's consolidated budget in the tax non-payment effects: tax avoidance and tax evasion. Tax losses (tax gap) is treated as the difference between the amount of potential taxes and contributions that could be collected if the taxpayers correctly calculated and paid on time in accordance with the provisions of the legislation and actually paid taxes and contributions.

We present a time-variability study of young stellar objects (YSOs) in the Serpens South cluster performed at 3.6 and 4.5 μm with the Spitzer Space Telescope; this study is part of the Young Stellar Object VARiability project. We have collected light curves for more than 1500 sources, including 85 cluster members, over 38 days. This includes 44 class I sources, 19 sources with flat spectral energy distributions (SEDs), 17 class II sources, and five diskless YSO candidates. We find a high variability fraction among embedded cluster members of ∼70%, whereas young stars without a detectable disk display no variability. We detect periodic variability for 32 sources with periods primarily in the range of 0.2–14 days and a subset of fast rotators thought to be field binaries. The timescale for brightness changes are shortest for stars with the most photospheric SEDs and longest for those with flat or rising SEDs. While most variable YSOs become redder when fainter, as would be expected from variable extinction, about 10% get bluer as they get fainter. One source, SSTYSV J183006.13−020108.0, exhibits “cyclical” color changes.
Internal Variations in Empirical Oxygen Abundances for Giant H ii Regions in the Galaxy NGC 2403
Authors: Mao Ye-Wei , Lin Lin , Kong Xu
Published: February 2018

This paper presents a spectroscopic investigation of 11

 regions in the nearby galaxy NGC 2403. The

 regions are observed with a long-slit spectrograph mounted on the 2.16 m telescope at XingLong station of National Astronomical Observatories of China. For each of the

 regions, spectra are extracted at different nebular radii along the slit-coverage. Oxygen abundances are empirically estimated from the strong-line indices R23,

,

, and N2 for each spectrophotometric unit, with both observation- and model-based calibrations adopted into the derivation. Radial profiles of these diversely estimated abundances are drawn for each nebula. In the results, the oxygen abundances separately estimated with the prescriptions on the basis of observations and models, albeit from the same spectral index, systematically deviate from each other; at the same time, the spectral indices R23 and

are distributed with flat profiles, whereas N2 and

exhibit apparent gradients with the nebular radius. Because our study naturally samples various ionization levels, which inherently decline at larger radii within individual

 regions, the radial distributions indicate not only the robustness of R23 and

against ionization variations but also the sensitivity of N2 and

to the ionization parameter. The results in this paper provide observational corroboration of the theoretical prediction about the deviation in the empirical abundance diagnostics. Our future work is planned to investigate metal-poor

 regions with measurable T
e, in an attempt to recalibrate the strong-line indices and consequently disclose the cause of the discrepancies between the empirical oxygen abundances.
Frequency Dependence of Helioseismic Measurements of the Center-to-Limb Effect and Flow-induced Travel-time Shifts
Authors: Chen Ruizhu , Zhao Junwei
Published: February 2018

Time–distance helioseismology measures acoustic travel times to infer the structure and flow field of the solar interior; however, both the mean travel times and the travel-time shifts suffer systematic center-to-limb variations, which complicate the interpretation and inversions of the time–distance measurements. In particular, the center-to-limb variation in travel-time shifts (CtoL effect) has a significant impact on the inference of the Sun’s meridional circulation, and needs to be removed from the helioseismic measurements, although the observational properties and the physical cause of the CtoL effect have yet to be investigated. In this study, we measure the CtoL effect in the frequency domain using Doppler-velocity data from the Solar Dynamics Observatory/Helioseismic and Magnetic Imager, and study its properties as a function of disk-centric distance, travel distance, and frequency of acoustic waves. It is found that the CtoL effect has a significant frequency dependence—it reverses sign at a frequency around 5.4 mHz and reaches maximum at around 4.0 mHz before the sign reversal. The tendency of frequency dependence varies with disk-centric distance in a way that both the sign-reversal frequency and the maximum-value frequency decrease closer to the limb. The variation tendency does not change with travel distance, but the variation magnitude is approximately proportional to travel distance. For comparison, the flow-induced travel-time shifts show little frequency dependence. These observational properties provide more clues on the nature of the CtoL effect, and also possibly lead to new ways of effect-removal for a more robust determination of the deep meridional flow.
Suzaku Observations of Heavily Obscured (Compton-thick) Active Galactic Nuclei Selected by the Swift/BAT Hard X-Ray Survey

Published: February 2018

We present a uniform broadband X-ray (0.5–100.0 keV) spectral analysis of 12 Swift/Burst Alert Telescope selected Compton-thick (

) active galactic nuclei (CTAGNs) observed with Suzaku. The Suzaku data of three objects are published here for the first time. We fit the Suzaku and Swift spectra with models utilizing an analytic reflection code and those utilizing the Monte-Carlo-based model from an AGN torus by Ikeda et al. The main results are as follows: (1) The estimated intrinsic luminosity of a CTAGN strongly depends on the model; applying Compton scattering to the transmitted component in an analytic model may largely overestimate the intrinsic luminosity at large column densities. (2) Unabsorbed reflection components are commonly observed, suggesting that the tori are clumpy. (3) Most of CTAGNs show small scattering fractions (<0.5%), implying a buried AGN nature. (4) Comparison with the results obtained for Compton-thin AGNs suggests that the properties of these CTAGNs can be understood as a smooth extension from Compton-thin AGNs with heavier obscuration; we find no evidence that the bulk of the population of hard-X-ray-selected CTAGNs are different from less obscured objects.
Dynamical Properties of Eccentric Nuclear Disks: Stability, Longevity, and Implications for Tidal Disruption Rates in Post-merger Galaxies
Authors: Madigan Ann-Marie , Halle Andrew , Moody Mackenzie , McCourt Michael , Nixon Chris , Wernke Heather
Published: February 2018

In some galaxies, the stars orbiting the supermassive black hole take the form of an eccentric nuclear disk, in which every star is on a coherent, apsidally aligned orbit. The most famous example of an eccentric nuclear disk is the double nucleus of Andromeda, and there is strong evidence for many more in the local universe. Despite their apparent ubiquity, however, a dynamical explanation for their longevity has remained a mystery: differential precession should wipe out large-scale apsidal-alignment on a short timescale. Here we identify a new dynamical mechanism which stabilizes eccentric nuclear disks, and explain for the first time the negative eccentricity gradient seen in the Andromeda nucleus. The stabilizing mechanism drives oscillations of the eccentricity vectors of individual orbits, both in direction (about the mean body of the disk) and in magnitude. Combined with the negative eccentricity gradient, the eccentricity oscillations push some stars near the inner edge of the disk extremely close to the black hole, potentially leading to tidal disruption events (TDEs). Order of magnitude calculations predict extremely high rates in recently formed eccentric nuclear disks (∼0.1–1

). Unless the stellar disks are replenished, these rates should decrease with time as the disk depletes in mass. If eccentric nuclear disks form during gas-rich major mergers, this may explain the preferential occurrence of TDEs in recently merged and post-merger (E+A/K+A) galaxies.
