Abstract
Unexpected power supply interruptions in the Shushufindi-Aguarico field represent a major issue for production and logistics. Although these interruptions are not frequent, they can severely affect operations, and because of the remote well locations, mobilization and security coordination, and HSE exposure starting-up the wells can be a challenge. To overcome these constraints, a solution was required that would enable remote well startups, reducing downtime and deferred production by 72%.
A process has been setup where a surveillance service identifies an interruption, proceeds with remote start-up, and finally confirms restarting. Using this service one can monitor operations and quickly take action in the event of a power supply interruption. After one such interruption, the control room received confirmation from the local engineering team to proceed with the remote well startup. The team used the surveillance service to confirm remote access to each well and identify when each well had started up. After restarting all the wells, the surveillance service was used to monitor performance during the stabilization period.
Use of the real-time surveillance service, together with support from the Artificial Lift Surveillance Centre, enables the engineering team to monitor operations prior to the interruption, remotely restart the wells, and confirm the wells had successfully restarted after the interruption. As a result, the 42 wells were started up in a record time of just 2.8 hours, instead of the estimated 16.8 hours if they were started up without the remote intervention of the engineering team.
This paper explains how the real-time surveillance helps improve the run life and uptime of Electrical Submersible Pumps (ESP) and so reduces production deferment in the Shushufindi-Aguarico wells of the Ecuadorian Oriental basin. The implementation of a robust surveillance workflow, together with real-time surveillance and an alarm notification system, has been shown to be effective in increasing ESP run life. It does by classification of alarms and the fast diagnostics of main root causes that helps to promptly identify remedial actions and/or recommendations. This workflow prevents the ESP from being operated outside its recommended operating conditions and experiencing excessive stress, reducing start/stops and downtime, and improving the downhole chemical injection program for scale inhibition.
Collapse Analysis of Perforated Pipes Under External Pressure

Published: March 2017

Abstract
This work is a numerical, analytical and experimental study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure. These types of pipes are a simple and economical technology widely used in our days as sand control meshes or perforated liners. In this work was considered a variation of geometric configurations (relation diameter/pipe thickness (OD/t)), distance between perforations, number of perforation on the circumferential and longitudinal directions and hole diameter.
First, was evaluated the reduction of the radial resistance to the external pressure through the real collapse of 12 pipes of 151 mm of diameter (8 with holes and 4 without). For the analytical part was calculated the collapse pressures using the API equations (API 1999), DNV equation (DNV, 2010) and four-hinge mechanism (ABBASSIAN & PARFITT 1998). For the numerical part was developed a tridimensional model on finite elements using ABAQUS, to obtain the pipe collapse pressure and validate the numerical model through the experimental results. The experimental and numerical results shows that the D/t relationship, initial imperfections (like ovalization) and material properties have important influence on the pipes resistance, although the perforation diameter and the axial space between them are the variables with most influence on the collapse resistance of perforated tubes. In general terms, when we compared the collapse pressures of pipes with holes and pipes without holes with similar properties was found a reduction of collapse pressure close to 10%, but some geometrical parameters of holes could reduce or increase this difference.

“Somebody is thinking about it”: Women as household managers in dual-earner families
Authors: Alby Francesca , Fatigante Marilena , Zucchermaglio Cristina 
Published: March 2017

In this work we focus, through a multi-method approach, on the managerial practices used by working mothers to deal with complex schedules and family needs in domestic life. We know, from previous studies, that dual earner families face substantial reorganizations of their domestic life, but there has been little research on how such reorganizations are accomplished within families. Findings draw on different data sets (focus groups, self-report charts, naturally occurring interactions) and, overall, show the centrality of managerial practices in the everyday domestic life of this kind of families. Results also show that housework is an arena for practical reasoning and thinking, making visible, through a detailed analysis of the sequential unfolding of actions, the managerial practices used by mothers to exploit and interactively coordinate different and competing activities. Finally, we suggest that managerial practices may constitute a form of care work through which mothers guarantee family members’ well-being.
Zusammenfassung
In dieser Arbeit nehmen wir mithilfe eines Multimethodenansatzes die Managementpraxis erwerbstätiger Mütter, die diese zur Bewältigung komplexer Zeitpläne und der Bedürfnisse der Familie anwenden, in den Blick. Aus vorausgegangenen Studien wissen wir, dass Doppelverdienerfamilien einer grundlegenden Umgestaltung des häuslichen Familienlebens gegenüberstehen, wobei bisher kaum darüber geforscht wurde, wie eine solche Reorganisation innerhalb der Familien erreicht wird. Die Erkenntnisse beruhen auf verschiedenen Datensätzen (Fokusgruppen, Zeitverwendungstagebücher, Aufzeichnung von Alltagsgesprächen) und verweisen auf die zentrale Bedeutung dieser Managementpraktiken im häuslichen Alltagsleben dieser Familien. Die Ergebnisse zeigen zudem, dass die Hausarbeit eine Arena praktischer Überlegungen und Denkmuster ist. Mithilfe einer detaillierten Analyse der sequentiellen Handlungsabfolgen in der Hausarbeit werden die Managementpraktiken sichtbar, die die Mütter nutzen, um unterschiedliche und miteinander in Wettstreit stehende Aktivitäten für sich zu verwerten und zu koordinieren. Abschließend schlagen wir vor, dass diese Managementpraktiken eine Form von Care- Arbeit darstellt, durch die Mütter das Wohlergehen der Familienmitglieder sicherstellen.

Réflexions autour d'un modèle géométrique pour la morphogénèse de la galle induite par Neuroterus numismalis (Olivier) ♂♀ (Hymenoptera Cynipidae) aux dépens du limbe des feuilles de chênes
Authors: Béguinot Jean 
Published: March 2017

Le dispositif de vascularisation des galles végétales induites par les arthropodes cécidogènes apparaît jouer un rôle essentiel dans la réalisation de leurs fonctionnalités, tant protectrice que nourricière, au profit de leurs locataires.
Selon que les galles proviennent d'une déformation locale de leur support végétal ou au contraire résultent d'une néo-formation, le schéma de vascularisation originel du sup¬ port est ordinairement globalement conservé dans le premier cas mais habituellement profondément modifié dans le second.
La galle induite sur feuilles de chênes par la génération printanière, sexuée, de Neuroterus numismalis paraît faire exception à cette tendance générale : bien que n'apparaissant pas résulter d'une néoformation, cette galle présente en effet un système de vascularisation profondément altéré tant dans l'aspect de ses modalités de branchement que dans sa symétrie de disposition radiale qui tranche sur le dispositif réticulé polygonal isotrope propre au limbe foliaire. Corrélativement, cette profonde altération paraît contredire la classique règle de conservation topologique des connexions au cours des évolutions morphologiques (Geoffroy Saint-Hilaire).
On suggère qu'il serait possible de lever ces contradictions en considérant qu'au delà des apparences, le système de vascularisation radial de cette galle peut se déduire naturellement d'une anamorphose géométrique appliquée au dispositif réticulé polygonal originel du limbe foliaire, respectant ainsi la topologie de vascularisation initiale propre au support, et ce, malgré la profonde transformation d'aspect qui en résulte. Cette hypothèse s'inscrit naturellement dans la façon de voir proposée par d'Arcy-Thompson. D'autre part, il est argumenté que les mécanismes d'induction susceptibles de générer une telle anamorphose s'inscrivent bien dans la gamme des capacités reconnues et modes d'action habituels des insectes cécidogènes.
An Infrared Study of the Dust Properties and Geometry of the Arched Filaments H ii Region with SOFIA/FORCAST
Authors: Hankins M. J. , Lau R. M. , Morris M. R. , Herter T. L. 
Published: March 2017

Abstract
Massive stellar clusters provide radiation (

) and winds (∼1000 km s−1) that act to heat dust and shape their surrounding environment. In this paper, the Arched Filaments in the Galactic center were studied to better understand the influence of the Arches cluster on its nearby interstellar medium (ISM). The Arched Filaments were observed with the Faint Object InfraRed CAMera for the SOFIA Telescope at 19.7, 25.2, 31.5, and 37.1 μm. Color–temperature maps of the region created with the 25.2 and 37.1 μm data reveal relatively uniform dust temperatures (70–100 K) over the extent of the filaments (∼25 pc). Distances between the cluster and the filaments were calculated assuming equilibrium heating of standard-size ISM dust grains (∼0.1 μm). The distances inferred by this method are in conflict with the projected distance between the filaments and the cluster, although this inconsistency can be explained if the characteristic grain size in the filaments is smaller (∼0.01 μm) than typical values. DustEM models of selected locations within the filaments show evidence of depleted abundances of polycyclic aromatic hydrocarbons (PAHs) by factors of ∼1.6–10 by mass compared to the diffuse ISM. The evidence for both PAH depletion and a smaller characteristic grain size points to processing of the ISM within the filaments. We argue that the eroding of dust grains within the filaments is not likely attributable to the radiation or winds from the Arches cluster, but may be related to the physical conditions in the Galactic center.
Efficiency of Synchrotron Radiation from Rotation-powered Pulsars
Authors: Kisaka Shota , Tanaka Shuta J. 
Published: March 2017

Abstract
Synchrotron radiation is widely considered to be the origin of the pulsed non-thermal emissions from rotation-powered pulsars in optical and X-ray bands. In this paper, we study the synchrotron radiation emitted by the created electron and positron pairs in the pulsar magnetosphere to constrain the energy conversion efficiency from the Poynting flux to the particle energy flux. We model two pair creation processes, two-photon collision, which efficiently works in young γ-ray pulsars (≲106 year), and magnetic pair creation, which is the dominant process to supply pairs in old pulsars (≳106 year). Using the analytical model, we derive the maximum synchrotron luminosity as a function of the energy conversion efficiency. From the comparison with observations, we find that the energy conversion efficiency to the accelerated particles should be an order of unity in the magnetosphere, even though we make a number of the optimistic assumptions to enlarge the synchrotron luminosity. In order to explain the luminosity of the non-thermal X-ray/optical emission from pulsars with low spin-down luminosity L
sd ≲ 1034 erg s−1, non-dipole magnetic field components should be dominant at the emission region. For the γ-ray pulsars with L
sd ≲ 1035 erg s−1, observed γ-ray to X-ray and optical flux ratios are much higher than the flux ratio between curvature and the synchrotron radiations. We discuss some possibilities such as the coexistence of multiple accelerators in the magnetosphere as suggested from the recent numerical simulation results. The obtained maximum luminosity would be useful to select observational targets in X-ray and optical bands.
Surveiller les animaux, conserver l’espèce
Authors: Lainé Nicolas 
Published: March 2017

Prenant pour objet d’étude le dispositif de surveillance de la tuberculose des éléphants mis en place au Laos depuis 2013, cet article vise à rendre compte des enjeux et des défis que représente la surveillance de maladie animale dans un contexte global de conservation des espèces. Il s’appuie sur une enquête ethnographique dont l’intention était de comprendre le rôle des populations locales et la place de leur savoir dans ce dispositif, mais aussi les agencements spécifiques et les transformations – dans le rapport à l’animal et parmi l’ensemble des acteurs concernés – induites par la mise en place de la surveillance. Les enjeux de l’alerte à la maladie sont multiples : aux enjeux sanitaires et économiques s’ajoutent ceux de la conservation de l’espèce. Il s’agit d’abord de brosser le tableau d’ensemble de la construction de la maladie en tant que zoonose globale : retracer la généalogie de l’alerte, faire le point sur les connaissances actuelles chez les pachydermes et sur leur expression au niveau mondial. Sur le plan local, la surveillance modifie le rapport à l’animal et celui de l’ensemble des acteurs concernés. Les résultats de l’enquête soulignent les difficultés rencontrées pour organiser la surveillance, mais aussi, dans le contexte de la patrimonialisation des pachydermes, la possibilité réelle, pour les cornacs, de faire évoluer leur savoir en transformant leur pratique en outil de gestion des crises sanitaires et environnementales.
Evaluating Practice-Based Learning
Authors: Logue Nancy C. 
Published: March 2017

Background:
Practice-based learning is an essential aspect of nursing education, and evaluating this form of learning is vital in determining whether students have the competence required to enter nursing practice. However, limited knowledge exists about the influences that shape how competence development is recognized in nursing programs. The purpose of this study was to explore the evaluation of practice-based learning from the students' standpoint.

Method:
A qualitative design based on institutional ethnography was used to investigate evaluation of practice-based learning with students, preceptors, and faculty in a preceptorship practicum.

Results:
The findings revealed how work associated with evaluation was organized by coexisting and often disparate influences within a nursing program and the workplaces where learning took place.

Conclusion:

The implications and recommendations of the inquiry are intended to encourage dialogue and action among stakeholders from education and practice to improve evaluation practices in preparing new members of the nursing profession. [

Published: March 2017

Background:
The effects of stress on nursing students' health and learning is important to educators. The purpose of this review was to critically integrate the literature related to the stress that nursing students experience regarding high-fidelity simulation (HFS).

Method:

Literature from multiple search engines and databases was systematically searched. Keywords and Boolean combinations included
nursing students
,
simulation
,
stress
,
anxiety
, and
self-efficacy
. Qualitative or quantitative studies published in English between 2010 and 2015 and studies including the effects of simulation on nursing student anxiety and stress were included. Seventeen studies were chosen.

Results:
Overall, students reported either moderate or high stress associated with simulation, but they rated the HFS experience as a valuable learning tool.

Conclusion:

This review demonstrated student acceptance of simulation as a learning strategy. However, more high-quality studies are needed to investigate techniques that can be implemented to decrease the negative effects of simulation stress on nursing students. [

Authors: St-Martin Genevieve , Bedard Angela , Nelmes JoAnne , Bedard James E.J. 
Published: March 2017

Background:
Few studies have focused on the genetic competencies of undergraduate nursing students. The aims of this study include measuring undergraduate nursing students' knowledge, perceived comfort, and attitude toward genetics, and gauging the effectiveness of a brief genetics education session.

Method:

Undergraduate nursing students (
N
= 32) were recruited to participate in a survey. A subset (
n
= 6) then participated in a 1-hour review of basic genetic concepts and activities, with applications to clinical scenarios. Both groups repeated the survey and their results were compared.

Results:
Students attending the education session had higher knowledge scores than the control group and reported higher levels of comfort with genetics-related tasks. No differences in student attitudes exist.

Conclusion:

This pilot study suggests that a brief but focused education session can increase the level of genetics knowledge and comfort in undergraduate nursing students. [
