Abstract
High-mass stars have generally been assumed to accrete most of their mass while already contracted onto the main sequence, but this hypothesis has not been observationally tested. We present ALMA observations of a

pc area in the W51 high-mass star-forming complex. We identify dust continuum sources and measure the gas and dust temperature through both rotational diagram modeling of

and brightness-temperature-based limits. The observed region contains three high-mass YSOs that appear to be at the earliest stages of their formation, with no signs of ionizing radiation from their central sources. The data reveal high gas and dust temperatures (

K) extending out to about 5000 au from each of these sources. There are no clear signs of disks or rotating structures down to our 1000 au resolution. The extended warm gas provides evidence that, during the process of forming, these high-mass stars heat a large volume and correspondingly large mass of gas in their surroundings, inhibiting fragmentation and therefore keeping a large reservoir available to feed from. By contrast, the more mature massive stars that illuminate compact

regions have little effect on their surrounding dense gas, suggesting that these main-sequence stars have completed most or all of their accretion. The high luminosity of the massive protostars (

), combined with a lack of centimeter continuum emission from these sources, implies that they are not on the main sequence while they accrete the majority of their mass; instead, they may be bloated and cool.
Isotropic–Nematic Phase Transitions in Gravitational Systems
Authors: Roupas Zacharias , Kocsis Bence , Tremaine Scott 
Published: June 2017

Abstract
We examine dense self-gravitating stellar systems dominated by a central potential, such as nuclear star clusters hosting a central supermassive black hole. Different dynamical properties of these systems evolve on vastly different timescales. In particular, the orbital-plane orientations are typically driven into internal thermodynamic equilibrium by vector resonant relaxation before the orbital eccentricities or semimajor axes relax. We show that the statistical mechanics of such systems exhibit a striking resemblance to liquid crystals, with analogous ordered-nematic and disordered-isotropic phases. The ordered phase consists of bodies orbiting in a disk in both directions, with the disk thickness depending on temperature, while the disordered phase corresponds to a nearly isotropic distribution of the orbit normals. We show that below a critical value of the total angular momentum, the system undergoes a first-order phase transition between the ordered and disordered phases. At a critical point, the phase transition becomes second order, while for higher angular momenta there is a smooth crossover. We also find metastable equilibria containing two identical disks with mutual inclinations between 90° and 180°.

Published: June 2017

Abstract
We present the radio luminosity function (LF) of flat-spectrum radio quasars (FSRQ), using the the largest and most complete sample to date. Cross-matching between the FIRST 20 cm and GB6 6 cm radio surveys, we find 638 flat-spectrum radio sources above 220 mJy at 1.4 GHz; of these, 327 are are classified and verified using optical spectroscopy data, mainly from Sloan Digital Sky Survey Data Release 12. We also considered flat-spectrum radio sources that lack both literature references and optical spectroscopy, and we identified 12 out of the 43 such sources to potentially be FSRQs, using their WISE colors. From the fully identified sample of 242 FSRQs, we derived the radio LF and cosmic evolution of blazars at 1.4 GHz, finding good agreement with previous work at 5 GHz. The number density of FSRQs increases dramatically to a redshift of z ∼ 2 and then declines for higher redshifts. Furthermore, the redshift at which the quasar density peaks is clearly dependent on luminosity, with more luminous sources peaking at higher redshifts. The approximate best-fit LF for a luminosity-dependent evolutionary model is a broken power-law with slopes ∼0.7 and ∼1.7 below and above the break luminosity,

erg s−1, respectively.
Magnetohydrodynamic Simulations for Studying Solar Flare Trigger Mechanism
Authors: Muhamad J. , Kusano K. , Inoue S. , Shiota D. 
Published: June 2017

Abstract
In order to understand the flare trigger mechanism, we conduct three-dimensional magnetohydrodynamic simulations using a coronal magnetic field model derived from data observed by the Hinode satellite. Several types of magnetic bipoles are imposed into the photospheric boundary of the Nonlinear Force-free Field model of Active Region (AR) NOAA 10930 on 2006 December 13, to investigate what kind of magnetic disturbance may trigger the flare. As a result, we confirm that certain small bipole fields, which emerge into the highly sheared global magnetic field of an AR, can effectively trigger a flare. These bipole fields can be classified into two groups based on their orientation relative to the polarity inversion line: the so-called opposite polarity, and reversed shear structures, as suggested by Kusano et al. We also investigate the structure of the footpoints of reconnected field lines. By comparing the distribution of reconstructed field lines and observed flare ribbons, the trigger structure of the flare can be inferred. Our simulation suggests that the data-constrained simulation, taking into account both the large-scale magnetic structure and small-scale magnetic disturbance (such as emerging fluxes), is a good way to discover a flare-producing AR, which can be applied to space weather prediction.

Abstract
We present a search for very high-energy gamma-ray emission from the Northern Fermi Bubble region using data collected with the High Altitude Water Cherenkov gamma-ray observatory. The size of the data set is 290 days. No significant excess is observed in the Northern Fermi Bubble region, so upper limits above 1 TeV are calculated. The upper limits are between

and

. The upper limits disfavor a proton injection spectrum that extends beyond 100 TeV without being suppressed. They also disfavor a hadronic injection spectrum derived from neutrino measurements.

Par quels chemins identificatoires passe le jeune garçon dans la construction de son masculin ? A rester uniquement du côté de la rivalité œdipienne et de l’angoisse de castration, on ne comprend pas le « manque à être homme » de certains hommes en analyse. Explorer les positions homosexuelles passives du garçon envers l’image paternelle et ses identifications féminines ouvre des possibilités d’écoute clinique et de compréhension du masculin.
Créativité transitionnelle et différence des sexes
Authors: Arènes Jacques 
Published: June 2017

Quand les espaces du masculin et du féminin ne sont plus gravés dans le marbre culturel, le genre – au sens psycho-dynamique du terme – se joue d’abord au cœur du psychisme des sujets, mais il est aussi tissé dans l’intersubjectivité. Il ne peut pas se penser de manière substantielle, mais comme un champ de forces complexe, se déployant dans et entre les personnes, tissé par de multiples liens et différences. Ce tissage du genre s’élabore dans l’espace transitionnel généré par le couple, en un « savoir » du corps de l’autre – et de son propre corps – s’accompagnant de contacts psychiques sectoriels. Les « frontières » de la différence des sexes constituent alors le reflet virtuel de l’énigme mutuelle constituée par deux types d’expériences, pour une part intraduisibles, sauf peut-être quand le temps favorable le permet, toujours ponctuellement. Comme dans cette expérience de mécanique quantique dans laquelle deux particules, aussi éloignées soient elles dans l’espace, demeurent mystérieusement liées.
The Filling Station as a Fresh Expression of church for consideration in the local congregational context: A practical-theological investigation
Authors: Nell Ian A. , Mellows Susan 
Published: June 2017

The findings of the Archbishop’s Council in their 2004 report, to the effect that traditional forms of church in Britain are under threat because of changing cultural patterns, emphasise the need to re-think church for our contemporary contexts. The ‘Fresh Expressions of church’ movement is one such initiative identified and approved of by the Archbishop’s Council. This article reports on research undertaken in a practical theological interpretation of The Filling Station, a Christian ministry that has grown significantly in its 10-year history and was formed as a missional endeavour in recognition of declining church attendance in traditional churches in Britain. This work explores whether The Filling Station is a Fresh Expression of church and whether it meets the values of authentic missional churches. In examining whether The Filling Station ought to be considered for import into appropriate local congregational contexts, it enquires whether it satisfactorily addresses prevailing social trends affecting churches, including consumerism and the need for identity.
Cotrimoxazole, a wonder drug in the era of multiresistance: Case report and review of literature
Authors: Batra Priyam , Deo Vishant , Mathur Purva , Gupta Amit Kumar 
Published: June 2017

AbstractAntimicrobial resistance is one of the greatest threats to human health worldwide. The rate of development of newer antibiotics is much slower than the rate of development of antibiotic resistance. A survey reported that it takes 15 years and US$800 million (including preclinical and clinical costs) to bring a single drug to the market, whereas the reuse of the older drugs for antimicrobial use takes $17 million, thereby circumventing 40% of the overall cost. The first case is a patient with nosocomial pyrexia of unknown origin who was given treatment with tigecycline and cefepime/tazobactam but failed to respond to the same. However, the patient responded to the treatment with cotrimoxazole. The second case is a patient with meningitis caused by an atypical zoonotic pathogen, Staphylococcus chromogenes. This is the first report of human infection with S. chromogenes, this being a common cause of bovine mastitis. The isolate was obtained from a patient of neurotrauma who developed meningitis after decompressive craniotomy. The strain was obtained from cerebrospinal fluid, blood, and shunt chamber pus. Cotrimoxazole was given for the treatment, and the patient improved after the treatment. Although the newer antibiotics have replaced sulfonamides in the treatment of many infections, they are still of great value and are the agents of choice in many infections. Sulfonamides have wide antimicrobial activity against both Gram-positive and Gram-negative bacteria, but their usefulness has diminished with the emergence of resistant strains. This paper reports cases of two different kinds of infections from a level 1 trauma center, who failed to respond to the newer antibiotics but showed a response to administration of cotrimoxazole.

Published: June 2017

Abstract
INTRODUCTION: The emergence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli has become an important challenge among pediatric patients with community-acquired urinary tract infection (UTI).
OBJECTIVES: The aim of this study was to assess the antimicrobial susceptibility patterns, associated risk factors and to survey the frequency of bla cefotaximase (CTX-M), bla temoneira (TEM), and bla sulfhydryl variable (SHV) genotypes in ESBL-producing E. coli isolated from children with community-acquired UTI.
METHODS: This was a prospective study conducted from November 2012 to March 2016 in a tertiary care center. E. coli isolated in urine cultures from children aged ≤18 years was identified and confirmed for ESBL production. ESBL-positive strains were screened for ESBL encoding genes. Chi-square test and Fisher’s exact test were used to compare the difference in antibiotic susceptibility with respect to ESBL positive and negative, and binary logistic regression was used to identify the risk factors associated with ESBL production.
RESULTS: Among 523 E. coli isolates, 196 (37.5%) were ESBL positive, >90% were resistant to cephalosporins, and 56% were resistant to fluoroquinolones. Least resistance was observed for imipenem, netilmicin, and nitrofurantoin (2%, 8.6%, 15.3%). Association between ESBL production and drug resistance was significant for ceftazidime (P < 0.001), cefixime (P < 0.001), cefotaxime (P = 0.010), ceftazidime-clavulanic acid (P < 0.001), levofloxacin (P = 0.037), and gentamicin (P = 0.047) compared to non-ESBL E. coli. CTX-M gene was the most prevalent (87.5%), followed by TEM (68.4%) and SHV (3.1%). Previous history of UTI and intake of antibiotics were the common risk factors.
CONCLUSION: ESBL-producing E. coli from community-acquired pediatric UTI carries more than one type of beta-lactamase coding genes correlating their increased antibiotic resistance. Aggressive infection control policy, routine screening for detecting ESBL isolates in clinical samples, and antimicrobial stewardship are the keys to prevent their dissemination in community settings.
Acylation-stimulating protein is a surrogate biomarker for acute myocardial infarction: Role of statins
Authors: Al-Kuraishy Hayder M. , Al-Gareeb Ali I. 
Published: June 2017

Abstract
BACKGROUND: Acylation-stimulating protein (ASP) is an adipokine synthesized within adipocytes environment due to adipocyte differentiation.
AIM: The aim of this study was to assess changes in ASP levels in patients with acute myocardial infarction (MI) and to correlate these variations with disease variables.
SUBJECTS AND METHODS: A total number of 111 patients previously and currently treated with rosuvastatin or atorvastatin presented with acute MI in a Coronary Care Unit, were divided into three groups, Group A: Thirty-nine patients treated with atorvastatin, Group B: Thirty patients treated with rosuvastatin, compared to 42 patients presented with MI not previously treated with statins were enrolled in this study. ASP and troponin-I levels and lipid profile were estimated in each group.
RESULTS: The effects of atorvastatin and rosuvastatin compared to nonstatins-treated group on the anthropometric and biochemical variables in patients with acute MI showed significant difference in all biochemical and anthropometric parameters P < 0.05. Serum ASP (nmol/l) levels were higher in control patients 57.25 ± 9.15 compared to atorvastatin-treated patients 48.43 ± 7.42 and rosuvastatin-treated patients 49.33 ± 6.52 P = 0.0124.
CONCLUSION: ASP levels are elevated in patients with acute MI and regarded as surrogate biomarker for acute MI also; therapy with statins leads to significant reduction in ASP levels compared to nonstatins-treated patients that presented with acute MI.
A clinico-pathological study of lupus nephritis based on the International Society of Nephrology-Renal Pathology Society 2003 classification system
Authors: Satish Suchitha , Deka Pallavi , Shetty Manjunath Sanjeev 
Published: June 2017

Abstract
INTRODUCTION: Lupus nephritis (LN) is a major complication of systemic lupus erythematosus (SLE). Renal involvement is a major determinant of the prognosis of SLE. The histological classification of LN is a key factor in determining the renal survival of patients with LN. Prompt recognition and treatment of renal disease are important, as early response to therapy is correlated with better outcome and renal biopsy plays an important role in achieving this.
OBJECTIVES: The objective of this study was to correlate the clinical and laboratory findings with histopathological classes of LN as per the 2003 International Society of Nephrology-Renal Pathology Society (ISN/RPS) classification system.
PATIENTS AND METHODS: Fifty-six patients with SLE, undergoing a renal biopsy for renal dysfunction were studied. The comparison of data from multiple groups was made by Pearson’s Chi-square test and between two groups by independent samples t-test. The values of P < 0.05 were considered statistically significant.
RESULTS: Of the 56 cases studied, 51 (91.1%) were females. The most common presenting symptoms were edema, arthralgia, and hypertension. Class IV (55.4%) was the most common class. Thirty-nine (69.6%) cases showed full house immunostaining. Hypertension, hematuria, proteinuria, and tu	bulo-interstitial disease showed a significant correlation (P < 0.05) with ISN/RPS classification, 2003.
CONCLUSION: Assessment and management of patients with suspected LN are greatly facilitated through information obtained by renal biopsy. Since renal morphology may predict long-term prognosis, and no clinical or laboratory feature uniformly predicts prognosis, it is important to study the constellation of features in LN for better patient management.
Anuṣṭhāna Yōga Vedānta of Yogacharya Raparthi Rama Rao: A comprehensive system of Yōga and Vedānta for the modern age
Authors: Kandi Suneetha 
Published: June 2017

Background:

Anuṣṭhāna Yōga Vedānta (AYV) is a comprehensive system developed by Yogacharya Raparthi Rama Rao, who attained the state of jīvaṇmukti (liberated while living). He was the spiritual head of Yoga Consciousness Trust, Vizinigiri, Andhra Pradesh, India. AYV comprises two integrated parts of yōga and vedānta emphasizing on the applied aspects of both.

Aim:
The aim of the current study was to focus on exploration and analysis of the AYV methodology and techniques.

Method:
Extensive review of five books written by Yogacharya in English represent the AYV method. One of the books was on biographical details of Yogacharya including his selected works and letters. The researcher attended lectures, listened to compact disc recordings, and interacted personally with Yogacharya for clarification and correction of concept and methodology of AYV.

Results:

Anuṣṭhāna Yōga is the amalgamation of Karma, Bhakti, Maṇtra, Kuṇḍalini, Jñāna, and Rāja Yōgas. All these yōgas are practiced in a systematic manner, initially with a focus on attaining the biṇdu or chaitaṇya darśan, and then practicing to be in the awareness of the chaitaṇya. Anuṣṭhāna vedānta deals with imparting knowledge that helps in analyzing and realizing the nature of one's true self.

Conclusion:
Yogacharya developed a systematic methodology of achieving the objectives of yōga and vedānta, which is tailored to the needs and levels of the modern person and is a surest, swiftest, and safest method. The stage-by-stage learning process of AYV guides all types of sādhakas in a phased manner and helps them progress to reach the goal.

Abstract

The strength of ordinary parenthood. Promoting life skills of parents

Parental life skills are proven to have a positive effect on parents’ well-being and on the development of their children. Recent developments in Dutch youth policies are more demanding of parents’ own strength and with that of their life skills. It is therefore important to determine which life skills or “21st century skills” parents indicate to require to strengthen their parenthood. Subsequently, professionals working with parents can connect their interventions to this. The aim of this study was to assess whether, according to parents, life skills effectively contribute to strengthen them. Semi structured interviews were conducted among 110 parents (74 mothers, 36 fathers) in different stages of parenthood, from pregnancy until the child moves out. Questions in the interview covered the five life skills: self- awareness, self- management, social awareness, relationship skills and responsible decision- making. Parents indicated a preference to develop themselves in dealing with stressful situations in the parental workplace and planning of tasks (self-management), dealing with conflicts and effective communication (relational skills), and making the right decisions for their child (responsible decision-making). Besides this, differences exist between parents in different stages of parenthood and their self-confidence as a parent. Parents feel most insecure during their child’s preschool puberty and adolescence periods. To strengthen parents, more attention must be given to what they indicate to require in terms of life skills, when they are feeling vulnerable and in which areas they would like to develop themselves. Then not only will a connection be made to the parents’ needs, a contribution to the well-being of families will be made as well.
