MHD Simulation for Investigating the Dynamic State Transition Responsible for a Solar Eruption in Active Region 12158
Authors: Lee Hwanhee , Magara Tetsuya 
Published: June 2018

Abstract
We present a magnetohydrodynamic model of solar eruption based on the dynamic state transition from the quasi-static state to the eruptive state of an active region (AR) magnetic field. For the quasi-static state before an eruption, we consider the existence of a slow solar wind originating from an AR, which may continuously make the AR magnetic field deviate from mechanical equilibrium. In this model, we perform a three-dimensional magnetohydrodynamic simulation of AR 12158 producing a coronal mass ejection, where the initial magnetic structure of the simulation is given by a nonlinear force-free field derived from an observed photospheric vector magnetic field. We then apply a pressure-driven outflow to the upper part of the magnetic structure to achieve a quasi-static pre-eruptive state. The simulation shows that the eruptive process observed in this AR may be caused by the dynamic state transition of an AR magnetic field, which is essentially different from the destabilization of a static magnetic field. The dynamic state transition is determined from the shape evolution of the magnetic field line according to the
κH-mechanism. This work demonstrates how the mechanism works to produce a solar eruption in the dynamic solar corona governed by the gravitational field and the continuous outflows of solar wind.

Abstract
The Kepler mission has provided exquisite data to perform an ensemble asteroseismic analysis on evolved stars. In this work we systematically characterize solar-like oscillations and granulation for 16,094 oscillating red giants, using end-of-mission long-cadence data. We produced a homogeneous catalog of the frequency of maximum power (typical uncertainty

), the mean large frequency separation (

), oscillation amplitude (

), granulation power (

), power excess width (

), seismically derived stellar mass (

), radius (

), and thus surface gravity (

dex). Thanks to the large red giant sample, we confirm that red-giant-branch (RGB) and helium-core-burning (HeB) stars collectively differ in the distribution of oscillation amplitude, granulation power, and width of power excess, which is mainly due to the mass difference. The distribution of oscillation amplitudes shows an extremely sharp upper edge at fixed

, which might hold clues for understanding the excitation and damping mechanisms of the oscillation modes. We find that both oscillation amplitude and granulation power depend on metallicity, causing a spread of 15% in oscillation amplitudes and a spread of 25% in granulation power from [Fe/H] = −0.7 to 0.5 dex. Our asteroseismic stellar properties can be used as reliable distance indicators and age proxies for mapping and dating galactic stellar populations observed by Kepler. They will also provide an excellent opportunity to test asteroseismology using Gaia parallaxes, and lift degeneracies in deriving atmospheric parameters in large spectroscopic surveys such as APOGEE and LAMOST.
HCN J = 4–3, HNC J = 1–0, H13CN J = 1–0, and HC3N J = 10–9 Maps of the Galactic Center Region. I. Spatially Resolved Measurements of Physical Conditions and Chemical Composition

Abstract
This supplement paper presents the maps of HCN J = 4–3, HNC J = 1–0,

J = 1–0, and HC3N J = 10–9 for the Galactic central molecular zone (CMZ), which have been obtained using the Atacama Submillimeter Telescope Experiment and Nobeyama Radio Observatory 45 m telescope. Three-dimensional maps (2D in space and 1D in velocity) of the gas kinetic temperature (T
kin), hydrogen volume density (

), and fractional abundances of eight molecules (HCN, HNC,

, HCO+,

, SiO, CS, and

) have been constructed from our and archival data. We have developed a method with hierarchical Bayesian inference for this analysis, which has successfully suppressed the artificial correlations among the parameters created by systematic errors due to the deficiency in the simple one-zone excitation analysis and the calibration uncertainty. The typical values of T
kin and

are

and

, respectively, and the presence of an additional cold, low-density component is also indicated. The distribution of high-temperature regions is poorly correlated with known active star-forming regions, while a few of them coincide with shocked clouds. Principal component analysis has identified two distinct groups in the eight analyzed molecules: one group with large PC1 and PC2 scores, and the other with a large T
kin dependence, which could be explained using two regimes of shock chemistry with fast (

) and slow (

) velocity shocks, respectively. This supports the idea that the mechanical sputtering of dust grains and the mechanical heating play primary roles in the chemical and thermal processes in CMZ clouds.

Published: June 2018

Objective.Ankylosing spondylitis (AS) is associated with increased risk for cardiovascular disease (CVD). Left ventricular (LV) hypertrophy is a strong precursor for clinical CVD. The aim of our study was to assess whether having AS was associated with increased prevalence of LV hypertrophy.Methods.Clinical and echocardiographic data from 139 AS patients and 126 age- and sex-matched controls was used. LV mass was calculated according to guidelines and indexed to height2.7. LV hypertrophy was considered present if LV mass index was > 49.2 g/m2.7 in men and > 46.7 g/m2.7 in women.Results.Patients with AS were on average 49 ± 12 years old, and 60% were men. The prevalence of hypertension (HTN; 35% vs 41%) and diabetes (5% vs 2%) was similar among patients and controls, while patients with AS had higher serum C-reactive protein level (CRP; p < 0.001). The prevalence of LV hypertrophy was higher in patients with AS compared to controls (15% vs 6%, p = 0.01). In multivariable logistic regression analysis, having AS was associated with OR 6.3 (95% CI 2.1–19.3, p = 0.001) of having LV hypertrophy independent of the presence of HTN, diabetes, and obesity. In multivariable linear regression analyses, having AS was also associated with higher LV mass (β 0.15, p = 0.007) after adjusting for CVD risk factors including sex, body mass index, systolic blood pressure, diabetes, and serum CRP (multiple R2 = 0.41, p < 0.001).Conclusion.Having AS was associated with increased prevalence of LV hypertrophy independent of CVD risk factors. This finding strengthens the indication for thorough CVD risk assessment in patients with AS.
Rio + 20 : un sommet délétère ? Les désillusions de la conférence des Nations unies sur le développement durable des 20-22 juin 2012
Authors: Guillot Philippe Ch.-A. 
Published: June 2018

Les réactions « à chaud » à la publication de la déclaration finale de la Conférence des Nations unies sur le développement durable ont fait étalage de profondes désillusions et déceptions. Après avoir rappelé comment est apparu le concept de développement durable, présenté son interprétation par le sommet de la Terre, réuni à Rio de Janeiro en 1992, et interprété son évolution jusqu’au sommet Rio + 20, cet article analyse la déclaration finale qui confère aux principes juridiques sur lesquels s’appuie le développement durable le caractère de principes du droit international général et comporte quelques avancées. En revanche, la notion d’économie verte destinée à revitaliser le concept de développement durable a été vidée de sa substance et les progrès attendus en matière de gouvernance ne sont pas au rendez-vous car la déclaration revient à des schémas classiques de coopération intergouvernementale. Enfin, il traite de certaines omissions de la déclaration (protection du milieu marin, accès à l’eau, déplacés environnementaux).
Les discours sur l’hérédité et la reproduction
Authors: Brandt Christina 
Published: June 2018

Ernst Haeckel fait partie d’un groupe de biologistes qui, au xixe siècle, ont développé une conception de l’hérédité en réaction à la théorie darwinienne de l’évolution. Déjà dans sa Generelle Morphologie (1866), Haeckel avait élaboré des lois de l’hérédité qu’il continua à discuter dans sa Natürliche Schöpfungsgeschichte (1868) ainsi que dans sa Perigenesis der Plastidule (1876). Cet article analyse l’approche de Haeckel dans le contexte des théories de l’évolution émergentes vers la fin du xixe siècle. On suit ici les différentes pistes de l’approche haeckelienne : des perspectives évolutionnaires s’étendant de Lamarck jusqu’à Darwin ont été mêlées à des concepts de la reproduction et de la croissance et s’enrichirent aussi de nombreuses métaphores culturelles et littéraires.

Ce papier peint est analysé en fonction du contexte de sa découverte et mis en relation avec les collections archéologiques retrouvées dans le sous-sol de la résidence. Se rencontrent ainsi ethnologie, histoire et archéologie afin d’ouvrir une fenêtre sur l’univers domestique du milieu du xviiie siècle à Québec.
L’art délicat du raffinage du sucre : la discrète évolution des techniques (France, fin xviie-fin xviiie siècle)
Authors: Villeret Maud 
Published: June 2018

Alors qu’à la fin du xviie siècle, le royaume de France importait du sucre raffiné en provenance d’Europe du Nord, en particulier des Provinces-Unies, à la fin du xviiie siècle, les raffineurs sont parvenus à satisfaire les besoins des consommateurs français. Grâce aux encouragements de l’État, à l’arrivée d’ouvriers étrangers qualifiés et à l’audace de certains négociants, le royaume de France est désormais auto-suffisant et la technique du raffinage maîtrisée. L’objectif de cette contribution est de comprendre comment le savoir-faire a été assimilé par les entrepreneurs français et comment les techniques ont évolué pour répondre à la demande croissante.
La pirogue et le grenier
Authors: Darmangeat Christophe 
Published: June 2018

Alain Testart a montré, il y a une trentaine d’années, que l’apparition des inégalités socio-économiques et de la richesse (définie par les paiements de mariage ou la compensation pour meurtre) n’est pas corrélée à l’agriculture, mais au stockage alimentaire. Cet article réexamine cette assertion à la lumière des rares sociétés à paiements qui, en raison de conditions écologiques particulières, ne pratiquent pas un tel stockage, en suggérant que la variable clé de la transition aux paiements est la production d’une catégorie particulière de biens.
La Déclaration Balfour, du « triomphe juif » au réveil du nationalisme arabe (1917-1920). Entre illusions et malentendus ?
Authors: Rota Olivier 
Published: June 2018

Cet article avance que ce sont les circonstances – mais aussi les malentendus – de l’année 1917 qui ont permis au sionisme d’obtenir des garanties du gouvernement britannique ; de la même façon que ce sont d’autres malentendus qui ont conduit à la prise en compte tardive de l’opposition arabe au projet sioniste. Le contexte confus de la Grande Guerre, le manque d’information, mais aussi les illusions, participèrent grandement à l’élaboration de la Déclaration Balfour, tout comme ils expliquent l’effondrement rapide des relations entre sionistes et Arabes après cette date.
Making a Connection: Family Experiences With Bedside Rounds in the Intensive Care Unit
Authors: Cody Shawn E. , Sullivan-Bolyai Susan , Reid-Ponte Patricia 
Published: June 2018

Background
The hospitalization of a family member in an intensive care unit can be stressful for the family. Family bedside rounds is a way for the care team to inform family members, answer questions, and involve them in care decisions. The experiences of family members with intensive care unit bedside rounds have been examined in few studies.

Objectives
To describe (1) the experiences of family members of patients in the intensive care unit who participated in family bedside rounds (ie, view of the illness, role in future management, and long-term consequences on individual and family functioning) and (2) the experiences of families who chose not to participate in family bedside rounds and their perspectives regarding its value, their illness view, and future involvement in care.

Methods
A qualitative descriptive study was done, undergirded by the Family Management Style Framework, examining families that participated and those that did not.

Results
Most families that participated (80%) found the process helpful. One overarching theme, Making a Connection: Comfort and Confidence, emerged from participating families. Two major factors influenced how that connection was made: consistency and preparing families for the future. Three types of consistency were identified: consistency in information being shared, in when rounds were being held, and in informing families of rounding delays. In terms of preparing families for the future, families appeared to feel comfortable with the situation when a connection was present. When any of the factors were missing, families described feelings of anger, frustration, and fear. Family members who did not participate described similar feelings and fear of the unknown because of not having participated.

Conclusion
What health care providers say to patients’ families matters. Families may need to be included in decision-making with honest, consistent, easy-to-understand information.
The art of establishing and maintaining contact with ancestors: A study of Bapedi tradition
Authors: Lebaka Morakeng E.K. 
Published: June 2018

Looking at Bapedi ancestor veneration constructively, one finds it a source of communication that enhances the community’s norms, values and personal well-being. The Bapedi community has a belief system that is based on the spiritual world, and this includes ancestor veneration. Communication with the spiritual world happens through sacrifices, songs and dance. Malopo is a ritual that not only binds the people to their ancestors (the ancestral realm) but also provides a healing therapy. The purpose of this study was to investigate the religious and social functions of ancestor veneration in the Bapedi society, as well as the relationship between culture, music and identity in veneration in the traditional healing Sepedi context. To achieve this aim, the study employed a naturalistic approach and data were collected through video recordings of malopo rituals, interviews and observations. The main questions the study addressed are (1) what are the religious and social functions of ancestor veneration in the Bapedi society? and (2) what is the relationship between culture, music and identity in veneration in Sepedi traditional healing context? The results demonstrated that ancestors are vital to Bapedi society, and the most effective ways of reaching them are through music and dance – malopo rituals, as well as divination bones.

Authors: Bagheri Seyyed Majid , Yadegari Maryam , Behpur Maliheh , Javidmehr Davood 
Published: June 2018

Objective:
In this study, antiurolithiasic and hepatoprotective effects of Ferula assa-foetida oleo-gum-resin (asafoetida) were evaluated in Wistar rats.

Methods:
Negative control rats were provided with ethylene glycol (EG, 1%) in drinking water for 28 days. In treatment group, asafoetida was used simultaneously once daily for 28 days at the dose of 25 mg/kg. 8-h urine was collected from experimental animals at the end of the experiment. Urine level of creatinine, uric acid, urea, K+, Ca2+, Mg2+, Na+, phosphorus, and serum level of transaminase (alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were evaluated. In addition, histopathological changes in kidney and liver were stained in hematoxylin and eosin.

Results:
Asafoetida showed a significant effect on urine volume; water intake and urinary ionic parameters were altered by EG, which elevated the calcium and inorganic phosphate; and asafoetida significantly reduced the elevated levels of these ions. In addition, asafoetida significantly elevated the urinary concentration of magnesium. ALT, AST, LDH, and ALP were elevated by EG and asafoetida significantly reduced the elevated levels of these parameters. The histological findings also showed improvement after treatment with the asafoetida.

Conclusion:
The presented data indicate that administration of asafoetida prevented the growth of urinary stones and also have hepatoprotective effect in experimental EG nephrolithiasis in Wistar rats.
El tratamiento de la información política e institucional en TVE
Authors: Soengas-Pérez Xosé , Elías-Pérez Carlos , López-Cepeda Ana María 
Published: June 2018

Esta investigación analiza la información política e institucional en los telediarios de TVE para conocer el tratamiento de los acontecimientos que protagonizan los partidos políticos, las instituciones y sus representantes. Metodología. Trabajamos con una metodología mixta. El análisis cuantitativo es necesario para determinar el grado de pluralidad formal y el cualitativo sirve para conocer los detalles de los enfoques de las noticias. Además, incluimos un grupo de discusión formado por cinco redactores para averiguar cómo funciona el proceso informativo en la televisión pública. Resultados y conclusiones. Los datos demuestran que el 97% de las noticias tienen un tratamiento formal correcto, pero estas cifras contrastan con los resultados del análisis de contenido. El 74% de los temas de información institucional tienen un enfoque que favorece, refuerza o avala la imagen del Gobierno y de los organismos afines.
A Rapid Method for the Determination of Biotin and Folic Acid in Liquid Milk, Milk Powders, Infant Formula, and Milk-Based Nutritional Products by Liquid Chromatography–Tandem Mass Spectrometry
Authors: Gill Brendon D , Saldo Sheila , Wood Jackie E , Indyk Harvey E 
Published: June 2018

Abstract
Background: Biotin and folate are B-group vitamins that play a critical role in numerous metabolic reactions, and they are supplemented to infant and adult nutritional formulas as free biotin and folic acid. Objective: We describe a rapid method for the analysis of biotin and folic acid that is applicable to liquid milk, milk powders, infant formula, and milk-based nutritional products. Methods: Samples are autoclaved, centrifuged, filtered, and analyzed by HPLC–MS/MS, with quantitation accomplished by the internal standard technique. Results: The method was shown to be accurate, with acceptable spike recovery (biotin: 96.5–108.2%; folic acid: 92.6–104.4%), and no bias (α = 0.05) against either a certified reference material (biotin: P = 0.70; folic acid: P = 0.23) or established analytical method (biotin: P = 0.10; folic acid: P = 0.48) was found. Acceptable precision was confirmed with repeatability relative standard deviation (RSDr) and Horwitz ratio (HorRat) values (biotin: RSDr = 0.5–5.6%, HorRatr = 0.1–0.6; folic acid: RSDr = 2.0–3.1%, HorRatr = 0.3–0.5). Method detection limit and ruggedness experiments further demonstrated the suitability of this method for routine compliance testing. Conclusions: This rapid method is intended for use in high-throughput laboratories as part of the routine product compliance release testing of biotin and folic acid in the manufacturing of infant formulas and adult nutritional products.
The effect of a person-centred and strength-based health intervention on recovery among people with chronic illness
Authors: Heggdal Kristin , Oftedal Bjørg , Hofoss Dag 
Published: June 2018

Background: Strengthening the health capacities of people diagnosed with a chronic illness is an essential part of secondary and tertiary prevention. However, research-based interventions focussed on health and recovery in chronic illness remain scarce. Additionally, these are often designed for specific diagnostic groups while healthcare workers are in need of more broadly applicable interventions that attend to personal resources for health. The aim of the present study was to trace patient recovery during an intervention designed to strengthen their bodily knowledge as an important resource for coping, recovery and health in chronic illness. Design and methods: The Outcome Rating Scale (ORS) was applied, as this instrument repeatedly measures progress in coping and recovery. Four dimensions were assessed: (1) individual (personal or symptomatic distress or wellbeing); (2) interpersonal (relational distress or wellbeing); (3) social (patient satisfaction with work, school and relationships) and (4) overall (general sense of wellbeing).Results: The sample comprised 13 men and 24 women who had been diagnosed with a range of long-term conditions and were attending the person-focussed health intervention in their community. Significant change was identified during the programme period. The findings indicate more improvement on the personal and general wellbeing dimensions than on the interpersonal and social dimensions. The number of participants scoring above the ORS cut-point of 25 increased by a factor of 1.7, demonstrating the programme’s efficiency.Conclusions: The results indicate that The Bodyknowledging Programme had a significant impact on the various forces driving recovery in chronic illness.
