Abstract
High-precision proper motions of the globular cluster 47 Tuc have allowed us to measure for the first time the cluster rotation in the plane of the sky and the velocity anisotropy profile from the cluster core out to about 13′. These profiles are coupled with prior measurements along the line of sight (LOS) and the surface brightness profile and fit all together with self-consistent models specifically constructed to describe quasi-relaxed stellar systems with realistic differential rotation, axisymmetry, and pressure anisotropy. The best-fit model provides an inclination angle i between the rotation axis and the LOS direction of 30° and is able to simultaneously reproduce the full three-dimensional kinematics and structure of the cluster, while preserving a good agreement with the projected morphology. Literature models based solely on LOS measurements imply a significantly different inclination angle (i = 45°), demonstrating that proper motions play a key role in constraining the intrinsic structure of 47 Tuc. Our best-fit global dynamical model implies an internal rotation higher than previous studies have shown and suggests a peak of the intrinsic V/σ ratio of ∼0.9 at around two half-light radii, with a nonmonotonic intrinsic ellipticity profile reaching values up to 0.45. Our study unveils a new degree of dynamical complexity in 47 Tuc, which may be leveraged to provide new insights into the formation and evolution of globular clusters.

Abstract
We have characterized the spectroscopic orbit of the TWA 3A binary and provide preliminary families of probable solutions for the TWA 3A visual orbit, as well as for the wide TWA 3A–B orbit. TWA 3 is a hierarchical triple located at 34 pc in the ∼10 Myr old TW Hya association. The wide component separation is 1.″55; the close pair was first identified as a possible binary almost 20 years ago. We initially identified the 35-day period orbital solution using high-resolution infrared spectroscopy that angularly resolved the A and B components. We then refined the preliminary orbit by combining the infrared data with a reanalysis of our high-resolution optical spectroscopy. The orbital period from the combined spectroscopic solution is ∼35 days, the eccentricity is ∼0.63, and the mass ratio is ∼0.84; although this high mass ratio would suggest that optical spectroscopy alone should be sufficient to identify the orbital solution, the presence of the tertiary B component likely introduced confusion in the blended optical spectra. Using millimeter imaging from the literature, we also estimate the inclinations of the stellar orbital planes with respect to the TWA 3A circumbinary disk inclination and find that all three planes are likely misaligned by at least ∼30°. The TWA 3A spectroscopic binary components have spectral types of M4.0 and M4.5; TWA 3B is an M3. We speculate that the system formed as a triple, is bound, and that its properties were shaped by dynamical interactions between the inclined orbits and disk.
Lyα Profile, Dust, and Prediction of Lyα Escape Fraction in Green Pea Galaxies

Published: August 2017

Abstract
We studied Lyman-α (Lyα) escape in a statistical sample of 43 Green Peas with HST/COS Lyα spectra. Green Peas are nearby star-forming galaxies with strong [O iii]λ5007 emission lines. Our sample is four times larger than the previous sample and covers a much more complete range of Green Pea properties. We found that about two-thirds of Green Peas are strong Lyα line emitters with rest-frame Lyα equivalent width

. The Lyα profiles of Green Peas are diverse. The Lyα escape fraction, defined as the ratio of observed Lyα flux to intrinsic Lyα flux, shows anti-correlations with a few Lyα kinematic features—both the blue peak and red peak velocities, the peak separations, and the FWHM of the red portion of the Lyα profile. Using properties measured from Sloan Digital Sky Survey optical spectra, we found many correlations—the Lyα escape fraction generally increases at lower dust reddening, lower metallicity, lower stellar mass, and higher [O iii]/[O ii] ratio. We fit their Lyα profiles with the H i shell radiative transfer model and found that the Lyα escape fraction is anti-correlated with the best-fit N
H i
. Finally, we fit an empirical linear relation to predict

from the dust extinction and Lyα red peak velocity. The standard deviation of this relation is about 0.3 dex. This relation can be used to isolate the effect of intergalactic medium (IGM) scatterings from Lyα escape and to probe the IGM optical depth along the line of sight of each

Lyα emission-line galaxy in the James Webb Space Telescope era.
L’art de la fugue : les droits des femmes à l’Assemblée générale de l’ONU
Authors: Tordjman Simon 
Published: August 2017

Depuis 1946, date du vote unanime de la première résolution sur « les droits politiques de la femme », la question des droits des femmes s’est maintenue quasiment sans interruption à l’ordre du jour de l’Assemblée générale des Nations unies. Jusqu’en 2016, elle a donné lieu à l’adoption régulière et largement consensuelle de près de 350 résolutions. Cette banalisation permet-elle pour autant d’établir la dépolitisation de cet organe principal de l’Organisation ? Assiste-t-on à la limitation de son « pouvoir de débattre » au profit d’une fonction essentiellement procédurale, limitée à la reconnaissance et à la validation de principes préalablement débattus dans d’autres espaces ? L’apparente neutralisation de l’Assemblée générale n’est pas pour autant synonyme d’évacuation de toute dimension politique. À rebours de l’idée selon laquelle la politisation de l’Assemblée générale se réduit essentiellement aux clivages qui s’y donnent publiquement à voir, cette analyse entend montrer que ladite politisation s’y déploie également « par décentrement », selon des registres spécifiques, dans le cadre et en relation avec d’autres espaces institutionnels (conférences mondiales, ECOSOC, Conseil de sécurité).
Une représentation dépolitisée ? L’Organisation internationale du travail de 1919 à nos jours
Authors: Louis Marieke 
Published: August 2017

Le but de cette analyse est de dévoiler, dans une perspective socio-historique, les logiques séculières de dépolitisation à l’œuvre au sein de l’Organisation internationale du travail autour d’une question en apparence très politique : la représentation tripartite des gouvernements, des travailleurs et des employeurs. Nous distinguons une dépolitisation positive de la représentation, découlant d’une adhésion historique de l’institution au paradigme fonctionnaliste, et une dépolitisation négative, qui vise à discréditer le débat sur la représentation. Souvent complémentaires, ces deux logiques enserrent, voire étouffent, les séquences de politisation de la représentation, qui se manifestent sur un mode principalement contestataire, notamment au sujet de la composition du Conseil d’administration de l’OIT. Dans les deux cas, tout est entrepris pour faire de la représentation une question d’ordre technique et administratif et non l’objet d’un débat politique, jugé néfaste au bon fonctionnement de l’organisation.
Sécurité et transformations du système productif : application à l’industrie française du charbon (1817-1988)
Authors: Conus Marie-France , Escudier Jean-Louis 
Published: August 2017

Cet article s’inscrit dans la vérification de l’hypothèse du développement des hommes en liaison avec le mouvement long de l’économie. Les données relatives au nombre de tués dans l’industrie houillère publiées par la Statistique de l’Industrie Minérale ont été choisies comme mesure des transformations de la sécurité minière. Dans les périodes d’extraction intensive, l’accumulation du capital combinée à l’insuffisance du processus innovatif et à une surexploitation des hommes favoriserait la recrudescence des accidents. En revanche, les périodes de dépression seraient favorables à une amélioration de la sécurité. Après l’extraction intensive du premier tiers du XIX e siècle, caractérisée par un très fort taux de dangerosité, dès 1840 le niveau de qualification s’élève et la nature est mieux maîtrisée. L’extension de la production durant le Second Empire remet partiellement en cause ces avancées. Entre 1871 et 1894, le nombre d’accidents mortels diminue et la protection s’organise. Avec le retour à la prospérité économique, la nouvelle structure des forces productives est propice à des accidents dévastateurs telle l’explosion de Courrières en 1906. Dans la dépression de l’entre-deux-guerres, l’introduction de la mécanisation et de l’électrification améliore la sécurité. L’intensification de la production après 1945 ne s’accompagne plus d’une recrudescence des accidents mortels : désormais savoir, sécurité et développement des hommes sont au cœur de l’efficacité des houillères.
« Ceux des plages » et « Ceux des collines » : les « paysans » des villages littoraux dans le Japon prémoderne
Authors: Gotô Masatoshi 
Published: August 2017

Les habitants de villages de l’époque d’Edo, même s’ils étaient indistinctement désignés par le terme hyakushō , n’étaient pas tous des agriculteurs. Dans les zones côtières, on trouvait ainsi parmi ces « paysans » des pêcheurs, qui pouvaient constituer leurs propres villages, où coexister avec des agriculteurs au sein des mêmes communautés. À partir de l’exemple de la péninsule de Bōsō, l’article illustre les tensions autour du contrôle des ressources entre populations liées à l’agriculture (« ceux des collines ») et groupes tirant leur subsistance de la mer (« ceux des plages »). Au sein du monde rural, les populations de pêcheurs apparaissent à la fois marginalisées par les représentations dominantes de la paysannerie, mais aussi soucieuses d’affirmer une identité originale, distincte de celle des agriculteurs, afin de garder le monopole de certaines activités, et surtout de l’espace maritime.
Réflexions sur le statut de bourgeois à Edo et Ōsaka au XVII e siècle
Authors: Yoshida Nobuyuki , Tsukada Takashi 
Published: August 2017

Le statut de « bourgeois » ( chōnin ) dans le Japon de l’époque prémoderne est le produit de la construction, au tournant des xvi e et xvii e siècles, d’une multitude de villes nouvelles où se concentra la population des marchands et des artisans. Selon les principes d’organisation sociale et politique de cette époque, le statut de bourgeois garantissait aux citadins un droit de propriété foncière en échange de l’accomplissement d’un « service » ( yaku ) envers l’autorité publique seigneuriale, imposé au bourgeois dans le cadre de communautés autonomes de rue ou de quartier. À partir de l’exemple des deux grandes métropoles shogounales d’Edo et d’Ōsaka au xvii e siècle, l’article se penche sur l’évolution de quelques rues, en montrant les changements rapides qui affectèrent le statut de bourgeois, du fait des modifications de la structure de la propriété dues aux transactions foncières, mais aussi de la montée de la population locative.
Le marché des paris sportifs dans le football : le cas de la Belgique de 1922 à 1980
Authors: Breuil Xavier 
Published: August 2017

Au cours du dernier Euro de football, disputé en France en 2016, le montant des sommes misées en ligne par les parieurs a battu un nouveau record dans l’Hexagone : 156 millions d’euros pour les seuls matches du premier tour, soit davantage que pour tous les matches de la dernière coupe du monde au Brésil en 2014. L’importance prise par les paris sportifs dans de nombreux pays du monde invite à interroger les origines de cette pratique dans les différents pays de football. Appuyé sur des sources variées, cet article se propose d’étudier la construction et le fonctionnement du marché des pronostics en Belgique, de 1922 à 1980. Il souligne l’originalité du modèle développé dans ce pays, tant du point de vue de la nature des sociétés de paris, que du rôle joué par la fédération nationale de football.
The Ability of an Aftermarket Helmet Add-On Device to Reduce Impact-Force Accelerations During Drop Tests
Authors: Breedlove Katherine M. , Breedlove Evan , Nauman Eric , Bowman Thomas G. , Lininger Monica R. 
Published: August 2017

Context:
The Guardian Cap provides a soft covering intended to mitigate energy transfer to the head during football contact. Yet how well it attenuates impacts remains unknown.

Objective:
To evaluate the changes in the Gadd Severity Index (GSI) and linear acceleration during drop tests on helmeted headforms with or without Guardian Caps.

Design:
Crossover study.

Setting:
Laboratory.

Patients or Other Participants:
Nine new football helmets sent directly from the manufacturer.

Intervention(s):
We dropped the helmets at 3 velocities on 6 helmet locations (front, side, right front boss, top, rear right boss, and rear) as prescribed by the National Operating Committee on Standards for Athletic Equipment. Helmets were tested with facemasks in place but no Guardian Cap and then retested with the facemasks in place and the Guardian Cap affixed.

Main Outcome Measure(s):
The GSI scores and linear accelerations measured in g forces.

Results:
For the GSI, we found a significant interaction among drop location, Guardian Cap presence, and helmet brand at the high velocity (F10,50 = 3.01, P = .005) but not at the low (F3.23,16.15 = 0.84, P = .50) or medium (F10,50 = 1.29, P = .26) velocities. Similarly for linear accelerations, we found a significant interaction among drop location, Guardian Cap presence, and helmet brand at the high velocity (F10,50 = 3.01, P = .002, ω2 = 0.05) but not at the low (F10,50 = 0.49, P = .89, ω2 &lt; 0.01, 1–β = 0.16) or medium (F5.20,26.01 = 2.43, P = .06, ω2 &lt; 0.01, 1–β = 0.68) velocities.

Conclusions:
The Guardian Cap failed to significantly improve the helmets' ability to mitigate impact forces at most locations. Limited evidence indicates how a reduction in GSI would provide clinically relevant benefits beyond reducing the risk of skull fracture or a similar catastrophic event.

Authors: Bhuyan Lipsa , Goutham Balasubramanya , Chinnannavar Sangamesh N , Kundu Madhurima , Jha Kunal , Behura Shyam S 
Published: August 2017

ABSTRACT

Aim
The aim of this study was to evaluate the prevalence of dental anomalies (DAs) in Odisha population using panoramic radiographs.

Materials and methods
In this study, 1,080 panoramic radiographs were evaluated for DAs. Dental records were reviewed for diagnostic confirmation. Anomalies related to the shape, size, position of teeth, and number of roots (supernumerary roots) were evaluated.

Results
The study results showed the prevalence of DAs to be 35.27%. The most prevalent was dilaceration, which was seen in 46.71% cases followed by peg laterals in 20.99%.

Conclusion
Dental anomalies were present in more than one-third of the study group, which was mostly related to shape of the teeth. Early diagnosis of these DAs helps in avoiding complications.

Clinical significance
Identification of DAs requires proper examination and thereby subsequent correct diagnosis. These anomalies can pose complications in normal functioning of orofacial complex. The knowledge of the prevalence of such anomalies aids dental practitioners for a proper treatment plan.

Study on Personality Types of Dentists in different Disciplines of Dentistry
Authors: Anil Sukumaran , Hussein Farouk Ahmed , Alahmari Albatool S , Almubarak Sara H , Alateeq Sahar A 
Published: August 2017

ABSTRACT

Aim
The purpose of this study was to determine the most common personality type among dentists in seven selected clinical dentistry specialties using the Myers–Briggs Type Indicator (MBTI) and to compare between these different types of personalities.

Materials and methods
A survey containing the MBTI and demographic and practice questions was used to assess the personality styles of 243 dental specialists in Riyadh, Saudi Arabia. The survey results were analyzed using descriptive statistics.

Results
The results of the MBTI for 243 specialist dentists revealed, generally, a higher percentage of scoring for introversion (I) with an average of 65% than extroversion (E). The study identified 10 common personality types among these specialists: ISTJ, ISFJ, INFJ, ISTP, INFP, INTP, ENFP, ENTP, ENFJ, and ENTJ (extraversion–introversion (E–I), sensing–intuition (S–N), thinking–feeling (T–F), and judging–perception (J–P)). The dominant personality type in all seven clinical specialties in dentistry was ISTJ, with an average of 54%.

Conclusion
The personality types showed variation among the seven clinical dentistry specialties. However, among these seven clinician's specialties in dentistry, more than 50% of the individuals shared one common type of personality (ISTJ).

Clinical significance
The identification of the personality type might help in their association with coworkers, students, and patients as well as knowing the individual preferences toward different specialties in dentistry.

Current prescribing Practices for Antibiotic Prophylaxis: A Survey of Dental Practitioners
Authors: Rivera-Hidalgo Francisco , Spittle Leah S , Muzzin Kathleen B , Campbell Patricia R , DeWald Janice P 
Published: August 2017

ABSTRACT

Aim
Antibiotic prophylaxis guidelines have been developed for health care and dentistry. The authors examined whether dentists were following the 2007 American Heart Association (AHA) and the 2012 American Association of Orthopaedic Surgeons (AAOS) recommendations for antibiotic prophylaxis.

Materials and methods
A survey was sent to 600 dentists in the south-central region of the United States. The survey examined dentists’ prescribing practices for patients with cardiac and prosthetic joint replacements, antibiotic regimen prescribed, confidence in their prescription decisions, and dentistry's contribution to antibiotic resistance.

Results
The response rate was 28.7% (n = 172). Dentists followed the 2007 AHA guidelines for patients with a history of infective endocarditis (95%), and cardiac valves repaired with prosthetic materials (76%) or animal/donor tissue (61%). For prosthetic joint replacement, 72% prescribed antibiotic prophylaxis within the first 2 years after placement and 58% continued to prescribe after 2 years. Amoxicillin was the most frequently prescribed antibiotic for cardiac conditions (92%) and prosthetic joint replacements (77%). No significant differences were found in relation to dentists’ gender (p = 0.75), year of graduation (p = 0.71), scope of practice (p = 0.30), and their confidence in their prescription decisions; 73% believed taking multiple doses of antibiotics leads to antibiotic resistance.

Conclusion
The majority of dentists were following the 2007 AHA guidelines. Confusion regarding the 2012 AAOS guidelines for prosthetic joint replacement was evident.

Clinical significance
Keeping current with changing antibiotic prophylaxis guidelines ensures dentists are providing the best evidence-based dentistry for their patients.

Sealing Ability of Esthetic Post and Core Systems
Authors: Almohareb Thamer 
Published: August 2017

ABSTRACT

Aim
To review the literature on the sealing ability of esthetic post systems with different cementation techniques.

Background
An important factor for successful root canal treatment is the development of a coronal seal to the treated root canal system.

Review result
The current literature describes promising results using fiber posts with a dual-cure, self-etch resin cement system. However, none of the published results describe a post system or cementation technique that achieved a homogeneous and tight coronal seal.

Conclusion
Fiber post systems appear to be favorable alternatives to metallic or ceramic post systems. Furthermore, dual-cure, self-etch resin cement systems represent superior alternatives to other cement systems.

Clinical significance
The clinician should be aware of the differences between various post systems and different cement systems to select and apply the most appropriate post and cement in each clinical situation.

Approaches for integrating Ayurveda with Conventional System in a Multispeciality Hospital for Management of Osteoarthritis (Knee)
Authors: Gupta Vikas , Padhi MM , Bhat Sulochana 
Published: August 2017

ABSTRACT

Introduction
Udupa Committee Report 1958, Indian Health Policy 1983, National Population Policy 2000, ISM and H Policy 2002, and the National Rural Health Mission are some of the policy recommendations for mainstreaming of Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy. Based on these recommendations, the physical mainstreaming for patient care and research is established but is not popularized in some hospitals and among health care providers due to various reasons.

Aim
To study the feasibility of integrating Ayurveda with allopathic system in the management of Osteoarthritis (OA) (knee).

Materials and methods
This operational study was conducted at Safdarjung Hospital, New Delhi, India, in collaboration with the World Health Organization, India office. The study covered 252 patients of OA knee, out of which 201 completed the study. For the management of OA, standardized Yogaraja Guggulu, Ashwagandha, and Narayan taila were used along with lifestyle and dietary recommendations.

Results
Among 201 patients who completed the study period of 8 weeks, there was statistically significant improvement in signs and symptoms, King George's Medical College (KGMC)and Visual Analog Scale (VAS) scores (p-value < 0.05). There was statistically significant reduction in the intake of rescue medicines and side effects of oral nonsteroidal anti-inflammatory drug. The study could develop referrals from orthopedics department to Ayurvedic unit for management of OA knee.

Conclusion
It was evident from the study that the Ayurvedic treatment is effective in the management of OA. It also concluded that continued communication and scientific approaches will ascertain actual integration and there is good scope for developing integration model in the management of OA. The Ayurveda health care providers were able to establish functional integration with their allopathic counterparts and were able to manage cross referrals.
