ORBITAL EVOLUTION OF MASS-TRANSFERRING ECCENTRIC BINARY SYSTEMS. I. PHASE-DEPENDENT EVOLUTION
Authors: Dosopoulou Fani , Kalogera Vicky
Published: June 2016

Observations reveal that mass-transferring binary systems may have non-zero orbital eccentricities. The time evolution of the orbital semimajor axis and eccentricity of mass-transferring eccentric binary systems is an important part of binary evolution theory and has been widely studied. However, various different approaches to and assumptions on the subject have made the literature difficult to comprehend and comparisons between different orbital element time evolution equations not easy to make. Consequently, no self-consistent treatment of this phase has ever been included in binary population synthesis codes. In this paper, we present a general formalism to derive the time evolution equations of the binary orbital elements, treating mass loss and mass transfer as perturbations of the general two-body problem. We present the self-consistent form of the perturbing acceleration and phase-dependent time evolution equations for the orbital elements under different mass loss/transfer processes. First, we study the cases of isotropic and anisotropic wind mass loss. Then, we proceed with non-isotropic ejection and accretion in a conservative as well as a non-conservative manner for both point masses and extended bodies. We compare the derived equations with similar work in the literature and explain the existing discrepancies.
ORBITAL EVOLUTION OF MASS-TRANSFERRING ECCENTRIC BINARY SYSTEMS. II. SECULAR EVOLUTION
Authors: Dosopoulou Fani , Kalogera Vicky
Published: June 2016

Finite eccentricities in mass-transferring eccentric binary systems can be explained by taking into account the mass loss and mass transfer processes that often occur in these systems. These processes can be treated as perturbations of the general two-body problem. The time-evolution equations for the semimajor axis and the eccentricity derived from perturbative methods are generally phase-dependent. The osculating semimajor axis and eccentricity change over the orbital timescale and are not easy to implement in binary evolution codes like MESA. However, the secular orbital element evolution equations can be simplified by averaging over the rapidly varying true anomalies. In this paper, we derive the secular time-evolution equations for the semimajor axis and the eccentricity for various mass loss/transfer processes using either the adiabatic approximation or the assumption of delta-function mass loss/transfer at periastron. We begin with the cases of isotropic and anisotropic wind mass loss. We continue with conservative and non-conservative non-isotropic mass ejection/accretion (including Roche-Lobe-Overflow) for both point-masses and extended bodies. We conclude with the case of phase-dependent mass accretion. Comparison of the derived equations with similar work in the literature is included and an explanation of the existing discrepancies is provided.
De la révolution à la réforme : chiisme et politique en Arabie saoudite
Authors: Louër Laurence
Published: June 2016

Le printemps arabe a marqué un nouveau tournant dans les relations entre le régime saoudien et sa minorité chiite, marqué par un double processus de radicalisation. Radicalisation d’une partie des leaders d’opinion chiites d’une part, dont l’ampleur doit cependant être relativisée. En effet, les émeutes, si elles persistent dans la région de Qatif, sont le fait d’une minorité et sont ouvertement condamnées par le Mouvement de la réforme et la majorité des leaders d’opinion chiites. Par ailleurs, si la position du Mouvement de la réforme est fragilisée, elle n’a pas été fondamentalement remise en cause et les dissidents, s’ils sont influents, ne disposent pas de larges bases politiques. C’est vrai y compris de Nimr al-Nimr. Radicalisation au sein du régime d’autre part. Avant 2012, la politique de la reconnaissance du Mouvement de la réforme avait fait les frais des luttes de factions internes à la dynastie Al Saoud, qui opposaient notamment le Roi Abdallah et le Prince héritier Nayef. Soutiens du Roi, les chiites étaient devenus une des cibles favorites du puissant prince Nayef lorsqu’il souhaitait signifier à Abdallah les limites de son pouvoir.
Le Liban et l’Iran à l’ombre du conflit entre l’Iran et l’Arabie saoudite
Authors: Khatchadourian Anaïs-Trissa
Published: June 2016

En Iran, plus grand pays chiite du monde, la victoire de la Révolution islamique en 1979 a créé un appel pour les populations chiites – souvent minoritaires – vivant dans les pays du Golfe. Outre que cela a suscité les inquiétudes des gouvernements sunnites en place, la révolution islamique de 1979 a également galvanisé les populations chiites ailleurs dans le monde arabe, et notamment au Liban, où l’Etat iranien essaie d’utiliser le facteur du chiisme pour étendre son influence. Mais que représente le terrain libanais dans la rivalité entre ces deux puissances régionales ? Nous étudions ici les relations entre le Liban et l’Iran, analysées à travers le prisme du conflit régional entre l’Arabie saoudite et l’Iran.

Si, depuis quelques années, militants et chercheurs commencent à compter les morts sur les routes migratoires, ils ont tendance à se focaliser sur l’arc méditerranéen, négligeant la frontière franco-britannique que l’on pourrait qualifier de nasse calaisienne. Accords européens, traités bilatéraux et leurs corollaires sécuritaires font en effet de cette frontière un mur meurtrier. Et les migrants n’ont d’autre choix que de prendre toujours plus de risques pour le franchir… au péril de leur vie.

Quelles options pour réduire la dépendance à la croissance du système de retraite français ?
Authors: Blanchet Didier , Bozio Antoine , Rabaté Simon
Published: June 2016

Le système de retraite français a été beaucoup réformé au cours des dernières décennies et ces réformes devraient avoir des effets financiers extrêmement significatifs. Mais deux questions restent ouvertes. La première est celle de la simplification d’un système peu lisible et non harmonisé. La seconde est que les réformes passées ne gèrent pas bien l’incertitude économique et démographique à laquelle le système est exposé. Sa sensibilité aux aléas de la croissance économique a même été accrue par les règles d’indexation sur les prix mises en place dès la fin des années 1980. Cet article utilise le modèle Pensipp pour explorer trois réponses possibles à ce dernier problème : deux réformes structurelles (comptes notionnels ou généralisation de la retraite par points) et un scénario paramétrique se contentant de rationaliser les règles d’indexation du système actuel.
Combien ont coûté les réformes de l’impôt sur les successions mises en place en France depuis 2000 ?
Authors: Goupille-Lebret Jonathan
Published: June 2016

Cet article évalue l’effet des réformes de l’impôt sur les successions intervenues depuis 2000 dont l’emblématique Loi en faveur du travail, de l’emploi et du pouvoir d’achat de 2007 (loi TEPA). Il s’appuie pour cela sur le modèle de microsimulation TaxR qui simule, au niveau microéconomique, les droits de succession en l’absence ou en présence des différentes réformes. Les réformes d’avant 2007 ont permis de maintenir le taux d’imposition et le nombre de successions imposables à leur niveau de 2000. La loi TEPA de 2007 a au contraire bénéficié quasi exclusivement aux héritiers en ligne directe et aux conjoints survivants des 10 % des successions les plus élevées, les autres successions étant déjà presque exonérées. L’ensemble des réformes a constitué un manque à gagner pour l’État de 3,9 milliards d’euros en 2010, dont 2,4 milliards imputables aux dispositifs de la loi TEPA de 2007 sur les successions. Nous estimons ensuite l’impact à long terme que la loi TEPA aurait pu avoir en présence ou en l’absence de réponses comportementales. La proportion d’héritiers en ligne directe imposables est passée de 20 % en 2000-2006 à 10 % en 2007-2010. Ce chiffre serait tombé à moins de 1 % en 2040 en cas d’utilisation optimale des allégements fiscaux. Les réformes de 2011 et 2012 ont toutefois limité le recours à de telles stratégies d’optimisation.
Communautés et entreprises : un nouveau rôle à jouer pour le gestionnaire
Authors: Cohendet Patrick , Simon Laurent , Sarazin Benoît
Published: June 2016

L’innovation dans les entreprises connaît aujourd’hui un bouleversement profond et irréversible. Il y a quelques années encore, elle était stimulée selon des méthodes formelles, du laboratoire de R&D jusqu’à la mise sur le marché. Toutefois, de nos jours, l’innovation tire sa source principale des communautés, c’est-à-dire des groupes sociaux informels constitués de représentants des métiers exercés au sein de l’entreprise ou d’utilisateurs de ses produits et services. Ces nouvelles sources d’innovation requièrent de la part des gestionnaires qu’ils s’adaptent à une réalité informelle et chaotique, donc difficile à contrôler et à reproduire.

Published: June 2016

Aneurysmal bone cyst originating from the surface of the bone, either within the cortex or subperiosteally, is an uncommon anatomic subtype. This article reports the clinical and radiologic evaluations and treatment outcomes of 10 patients with surface aneurysmal bone cysts that were surgically treated between 1982 and 2014. Mean age at the time of surgery was 22.4 years (range, 11–44 years). According to Capanna's radiographic evaluation criteria, 6 of the lesions were classified as type V and 4 were classified as type IV. Radiographically, periosteal shell formation was observed to be complete in 4 patients, partial in 3, and absent in 3, and 6 patients had Codman's angle or buttress formation. In 1 patient, computed tomography scan showed birdcage-like ossification attached to the surface of bone. Magnetic resonance imaging showed fluid-fluid levels in 5 patients. All of the patients had standard curettage and high-speed burr application as an adjuvant. No patient had local recurrence at the end of the follow-up period of 98.4 months (range, 13–288 months). These findings show the importance of careful radiologic evaluation and biopsy to better plan a treatment strategy when surface aneurysmal bone cyst is included in the differential diagnosis. The finding of fluid-fluid levels on magnetic resonance imaging or computed tomography is not pathognomonic for primary aneurysmal bone cyst; however, the absence of this finding does not rule out the diagnosis. The rate of local recurrence after curettage plus high-speed burr is reasonably low, and other adjuvant procedures should be used whenever needed. [

Definitive Treatment of Infected Shoulder Arthroplasty With a Cement Spacer
Authors: Mahure Siddharth A. , Mollon Brent , Yu Stephen , Kwon Young W. , Zuckerman Joseph D.
Published: June 2016

Infection in the setting of shoulder arthroplasty can result in significant pain, loss of function, and the need for additional surgery. As the use of shoulder arthroplasty increases, the medical and economic burdens of periprosthetic joint infection increase as well. The ideal management of infected shoulder prostheses has not been established. This report describes 9 patients from a single institution who had an infected shoulder arthroplasty that was definitively managed with a cement spacer. All patients had a minimum of 2 years of follow-up. Of the 9 patients in this study, 6 were men. Mean age was 73±9 years. Of the study patients, 1 had diabetes, 2 presented with Parkinson's disease, and 5 had a history of tobacco use. Average body mass index was 27.9±7 kg/m
2
. After mean follow-up of 4 years, none of the patients had clinical or radiographic evidence of infection. Functional outcomes, as measured by American Shoulder and Elbow Surgeons scores, were good or fair in 89% of patients, and the average American Shoulder and Elbow Surgeons score was 57. A review of recent literature suggested that the current findings were similar to those in studies reporting 1- or 2-stage revision procedures. Although cement spacers are typically used as part of a 2-stage revision procedure, the current findings suggest that cement spacers can be used effectively to eradicate infection and allow for acceptable functional recovery and range of motion in patients who have severe medical comorbidities and cannot tolerate additional surgery.

Intramedullary Nailing of Open Tibial Fractures: Provisional Plate Fixation
Authors: Ludwig Meryl , Hymes Robert A. , Schulman Jeff , Pitta Michael , Ramsey Lolita
Published: June 2016

Tibia fracture is the most common type of long bone fracture, and intramedullary nailing is the preferred treatment. In open fractures, a provisional plate is often used to maintain reduction. It is unknown whether this practice increases the risk of infection or other complications. This study retrospectively compared patients who were treated at a level 1 trauma center with intramedullary nailing of an open tibia fracture. Patients who were included: (1) were 18 years or older; (2) were treated between January 1, 2005, and June 30, 2013; (3) had an open fracture of the tibia; and (4) were treated operatively with intramedullary nailing, with or without provisional plate fixation. Patient sex, history of diabetes, history of smoking, mechanism of injury, and side of injury were analyzed. Postoperative complications included infection, delayed union or non-union, compartment syndrome, and death. After the authors controlled for age, Gustilo-Anderson type, and AO/Orthopaedic Trauma Association classification, they found that provisional plate use did not significantly increase the risk of infection (adjusted odds ratio, 1.64; 95% confidence interval, 0.51–5.32;
P
=.41) or any other complications (adjusted odds ratio, 1.24; 95% confidence interval, 0.46–3.35;
P
=.67). In the subgroup of patients who had a provisional plate (n=35), removal of the plate did not significantly decrease the risk of infection (adjusted odds ratio, 0.43; 95% confidence interval, 0.07–2.69;
P
=.36) or other complications (adjusted odds ratio, 0.55; 95% confidence interval, 0.12–2.46;
P
=.44). In open tibia fractures treated with intramedullary nailing, provisional plate stabilization, a valuable reduction aid, did not increase the risk of infection or other complications. Because of the small subgroup size, however, definitive conclusions cannot be drawn about removal of these provisional plates. [

Published: June 2016

Obtaining new knowledge accepted and used by practitioners remains a slow process. A dearth of knowledge translation research exists that explores how to effectively move knowledge to practice in the field of older adult mental health. The current article reports findings of a knowledge translation study that examined what factors enabled the adoption of a new clinical assessment framework, P.I.E.C.E.S.™, into practice in an older adult tertiary mental health unit. Theoretical insights of appreciative inquiry were used to guide the study. Qualitative methods were used, including focus groups with 20 staff and individual interviews with three leaders. The appreciative inquiry approach helped researchers successfully facilitate knowledge translation. Enabling factors included: (a) fostering positive energy to make continuous improvement, (b) working with team members across disciplines at all levels, and (c) using knowledge translation tools to enable and sustain the new practice.

Psychiatric Inpatient Bedside Handoff: Implementation of a Quality Improvement Project and Nurses' Responses
Authors: Givens Sarah E. , Skully Cathy , Bromley Gail
Published: June 2016

Psychiatric inpatient unit nurses implemented a quality improvement project to explore strategies to enhance the effectiveness of the change of shift communication between nurses and patients and obtain goals of care information. Three nurses championed a 6-month project to implement more efficient, patient-centered communication; influence patient outcomes; and assess nurses' perceptions about patient satisfaction. A survey established the level of nurse satisfaction regarding the length of time spent at change of shift obtaining patient information. Following a literature review, nurses used a standardized approach for their change of shift report, which they called patient bedside handoff. Nurses reported increased satisfaction with the length of time spent with the patient bedside handoff from a pre-implementation average score of 5.7 (somewhat satisfied) to a post-implementation score of 8.3 (very satisfied). This nurse-led quality improvement project helped illuminate perceived barriers to the implementation of patient bedside handoff and the changes in nurses' perceptions over time. [

Restauro storico y sacrae imagines en Évora bajo el gobierno del arzobispo don Teotonio de Braganza (1578-1602)
Authors: Serrão Vitor
Published: June 2016

En este ensayo se aborda la figura de don Teotonio de Braganza (arzobispo de Évora entre 1578 y 1602) y su legado en los programas de decoración artística y en el modo como adaptó los principios tridentinos del restauro storico y la revitalización de las sacra imagines en lugares de culto paleocristiano de su archidiócesis. Durante su munus se desarrolló un nuevo tipo de arquitectura sacra gracias a la participación de artistas con formación romana, como era el caso del arquitecto y escultor Pero Vaz Pereira. El arte que vio la luz en Évora a finales del siglo XVI, bajo el signo de la Contramaniera, alcanzó un esplendor que rivalizaría con el del reinado de Juan III y del humanista André de Resende. Con don Teotonio emergen nuevos temas y cultos, como los de los santos Mancio, Jordán, Comba y otros mártires considerados ‘eborenses’. El arzobispo encargó trabajos en Madrid, Roma y Florencia para dignificar la catedral de la ciudad y el monasterio de la Cartuja, fundado por él mismo. Su gobierno coincide, pues, con un capítulo principal del arte portugués bajo las orientaciones de Trento que merece ser debidamente analizado.
Hacia una estética del dónde
Authors: Bernabeu Larena Jorge , Aguiló Alonso Miguel
Published: June 2016

La manera de construir propia de la ingeniería ha sido considerada por el arte a partir de su carácter técnico y a menudo referida a la dialéctica utilidad-belleza, tanto por los propios ingenieros como por los historiadores del arte. En un mundo donde todo es técnico, se introducen algunos conceptos para precisar ese carácter, como forma, tipo, proceso y ciertas pautas o metas específicas, relacionadas con lo ligero, lo estricto y lo superfluo. Se considera después la gran dimensión de esas obras, que supera la escala del hombre, y su relación con el territorio resumida en paisaje. A continuación se introduce la confrontación con lo natural y la aportación de lo sublime y lo pintoresco como vías de interpretación y valoración de lo construido. Con la introducción de los significados y del paisaje cultural se concluye la conveniencia de considerar la ingeniería desde una perspectiva fenomenológica, subrayando la importancia del ‘donde’ para entender sus peculiaridades.

Published: June 2016

With the development and application of Biological chips and sensors, the demand for high-precision broadband driving power is increasingly rigorous. In order to improve the precision and reliability of the driving power, a high precision broadband closed-loop signal generator has been designed. It works by the high-accuracy amplitude detection circuit, the broadband voltage controlled amplifier and a micro-controller. The principles of amplitude detection circuit and amplifier circuit have been elaborated. Within 1 MHz ~ 200 MHz band, within 1 ~ 10 VPP amplitude range, under 50 Ω output impedance, the error of output signal amplitude can be controlled effectively. Precision is up to 0.15%. It meets the index and scientific research’s requirement.
Research on Energy Efficiency vs. Cooperative BSs’ Number of Coordinated Multi-Point Transmission
Authors: Liu Shuai , Dai Jianxin , Qi Jie
Published: June 2016

This paper focus on energy efficiency (EE) in Coordinated Multi-Point (CoMP) transmission with perfect feedback under single-user scenario. Considering the power consumed by cooperative BSs, an energy-efficient optimization function is established. This optimization goal is simplified after analyzing capacity of non-CoMP and CoMP. Then the relationship between energy efficiency and cooperative BSs’ number is analyzed. Simulation results show that when the selected number of cooperative BSs is smaller than a threshold, EE increases with the increasing of the number of cooperative BSs and when it exceeds the threshold, EE decreases with the increasing of the number of cooperative BSs.

A Portable PID Control Learning Tool by means of a Mobile Robot
Authors: Chia Kim Seng , Yap Xien Yin
Published: June 2016

A proportional-integral-derivative (PID) controller is a classical controller that has been applied in numerous applications. One learning lesson of PID control theory is to tune its proportional, integral, and derivative parameters so that the performance of system is optimal. Besides, teaching PID control theory verbally is challenging especially when transient response characteristics e.g. overshoot, rise time, and settling time are introduced. Thus, this study investigates the feasibility of a low cost mobile robot in conveying the knowledge of PID control theory. First, an inexpensive open-source mobile robot was modified so that the position of the robot can be recorded and visualized wirelessly. Second, a graphical user interface was built to visualize the movement of the robot. Lastly, the PID parameters were tuned and their effects were recorded and analyzed quantitatively. Findings show that the proposed method is capable of demonstrating the effects of P and D parameters correctly.

Authors: Watson Roger James , Lin Chih-Wei , Buschle Bill David , Gibbins Jon , Lucquiaud Mathieu Serge
Published: June 2016

Abstract—ACTTROM (Advanced Capture Testing in a Transportable Remotely-Operated Minilab) is a transportable test facility for bench-scale evaluation of post-combustion CO2 capture technologies using real industrial flue gases. It is designed to be remote-operable, requiring visits only once per month for maintenance and sample collection. ACTTROM is the first facility of its kind, owned and operated by academia for collaborative research in an industrial environment, and this has resulted in a number of unique developments to facilitate remote operation at an industrial host site. Specifically, it has been necessary to design the unit to automatically correct or mitigate the effects of fault conditions, and to be remotely-monitored via a user interface at 24 hour intervals.

Mobilisations politiques dans le monde arabe et nouvelle affirmation de la citoyenneté
Authors: Challand Benoît
Published: June 2016

Ce travail s’intéresse principalement aux liens entre la société et l’État dans le monde arabe avant et après les révolutions, et aborde l’impact que ces dernières ont eu à la fois sur les acteurs individuels et sur les nouvelles pratiques de la citoyenneté. Deux notions, celles de présentisme et d’intersectionnalité, sont mobilisées pour comprendre les nouvelles configurations qui déterminent les rapports horizontaux entre les citoyens et, verticaux, des citoyens avec la sphère du pouvoir. Cette analyse débouche sur l’inscription du processus révolutionnaire dans le long terme, et remonte à la période de la Nahda (Renaissance arabe) pour montrer la solidarité entre certaines dynamiques intellectuelles et politiques initiées à cette période. D’où, à la fin du travail, la tentative d’établir une nouvelle périodisation qui permettrait de lire autrement l’histoire du monde arabe contemporain.

Parti de la discussion de certaines lectures de la révolution syrienne qui la rabaissent à une simple émeute ou l’abordent à travers le prisme du religieux, ce travail montre comment les événements survenus en 2011 dans les différents territoires de ce pays ont eu pour but l’émancipation individuelle et collective, et qu’un tel élan vers la liberté et la dignité ne peut être objectivement décrit qu’à travers la catégorie de la « révolution ». L’article s’attarde sur la vision du politique dans le monde arabe telle qu’elle se reflète dans quelques travaux d’historiens, de sociologues ou de politistes, mais insiste sur l’approche de Michel Seurat (L’État de barbarie) qui mobilise des paradigmes comme le clanisme et le confessionnalisme pour approcher la société syrienne, et qui est encore à l’œuvre dans l’analyse de la phase historique que traverse actuellement ce pays.
Ce qu’atteint l’expérience du vouloir : Hume, Locke, Malebranche
Authors: Bergont Sophie
Published: June 2016

À partir de l’analyse d’un extrait de l’Enquête sur l’entendement humain (septième section, première partie), cet article confronte les conceptions humienne, lockienne et malebranchienne de l’expérience du pouvoir de vouloir. Il montre comment un certain nombre d’arguments directement repris à l’occasionnalisme malebranchien, sont dirigés par Hume contre la thèse lockienne d’une genèse de l’idée de pouvoir dans l’expérience réflexive de la causalité volontaire, et avance que ces constats textuels mettent en lumière l’existence d’une divergence majeure, interne à l’empirisme, quant à la portée de l’expérience que nous faisons du pouvoir de notre volonté.
L’impolitesse linguistique : vers un nouveau paradigme de recherche ?
Authors: Jobert Manuel
Published: June 2016

Cet article interroge la place de la notion d’impolitesse. Si la recherche actuelle s’intéresse de plus en plus aux énoncés impolis, les modèles théoriques utilisés sont encore fortement marqués par le modèle traditionnel de Brown & Levinson [1978], au moins pour un proposer un contrepoint. On s’intéressera principalement aux cadres présentés par Culpeper [1996] et Bousfield [2008].
You See!
Authors: Ranger Graham
Published: June 2016

The segment you see is employed as a parenthetical comment clause in initial, median and final position, where it may be said both to indicate the argumentative status of the clause it targets, as an explanation or justification for a previous representation, and to function as a politeness marker, in associating the cospeaker with propositions endorsed by the speaker, thereby defusing potential discord before it manifests itself. It is, in this second function, a marker of negative politeness (Brown & Levinson [1978]). Quirk et al [1985] also mention an alternative use of stressed you see to express triumph. In this paper I will propose an enunciative characterisation of you see which will, it is hoped, enable us to derive different, sometimes contradictory, interpretations of you see from the metalinguistic operations of which you see is the trace, and from observable differences in contextual configurations, including the identification of the related propositions or the position you see occupies relative to these propositions. From our study it emerges that you see is not in itself a marker of politeness, but that the operations which you see marks lend themselves to strategies including impoliteness (a Face Threatening Act – FTA) as well as negative and positive politeness, in the terms of Brown and Levinson. In some contexts it also appears to allow an uncertain speaker to elicit manifestations of positive politeness (backchannels) from the co-speaker. We are led to consider how the theory of enunciative operations might contribute to research in the fields of politeness and discourse structure.
La métaphore « inappropriée » : échec du partage sentimental et flou résultatif
Authors: Neveux Julie
Published: June 2016

La métaphore, à la différence de la comparaison, peut être perçue comme un acte de langage impoli. Cette étude donne les raisons linguistiques de cette différence : je définis la métaphore comme un énoncé de langue réappropriée pouvant être reçu comme un énoncé inapproprié, à certaines conditions d’infélicité signant l’échec du partage sentimental visé par la métaphore, et donnant lieu à un flou résultatif.

Authors: Saita Emanuela , Zanini Susanna , Minetti Enrico , Acquati Chiara
Published: June 2016

Increasing evidence has demonstrated that patients' involvement promotes better health care outcomes and cost-effectiveness of services. However, limited literature is available about the experience of living donor kidney transplantation and best practices to promote patients and donors' engagement. Aim of the present chapter is to review the literature about patient engagement in the context of chronic kidney disease, and to introduce an innovative protocol developed to promote potential donors and recipients' participation and adherence to care at the Niguarda Ca' Granda Hospital in Milan (Italy). Results are critical to reflect on the identification of best practices for patients' engagement in the context of chronic kidney disease. Through a better understanding of the emotional and affective dynamics and the relational implications that may influence the elaboration of the information given by health care providers, it will be possible to develop evidence-informed interventions.

Diabesity could be defined as a new global epidemic of obesity and being overweight with many complications and chronic conditions. The financial direct and indirect burden of diabesity is a real challenge in many Western health-care systems. Even if multidisciplinary protocols have been implemented, significant limitations in the chronic care management of obesity with type 2 diabetes concern costs and long-term adherence and efficacy. mHealth approach could overcome limitations linked with the traditional, restricted and highly expensive in-patient treatment of diabesity. The mHealth approach could help clinicians by motivating patients in remote settings to develop healthier lifestyles and could be implemented in the Chronic Care Model. A practical stepped-care model for diabesity, including mhealth approach and psychological treatments with different intensity, is discussed.

Authors: Postolache Gabriela , Oliveira Raul , Moreira Isabel , Postolache Octavian
Published: June 2016

In the last decade, rehabilitation process has shifted from medical management to issues that enhance quality of life, community participation, treatment and cost effectiveness. In this context physiotherapists design and implement new and/or tailored interventions that enhance physical and functional abilities, restore, maintain, and promote optimal physical function, wellness, fitness and quality of life. The aim of this review was to assess the extent, content, and outcomes of in-home physiotherapy interventions. A search was conducted in Medline, PEDro, and Cochrane Library and IEEE Xplore. RE-AIM and GRADE guidelines were used to report this review. The findings suggest that in-home physiotherapy tailored specifically to the people needs, functioning and disability has positive results, including patients' engagement in their healthcare. Integration of information and communication technology in-home physiotherapy has great potential to increase accessibility, quality and effectiveness of various interventions provided by physiotherapists.

Published: June 2016

Waiting for health care services have impact on people from several perspectives. First of all, seen from patients' point of view, due to psychologically and physically burden short waiting times are an indication of quality. Second, seen from health care systems' point of view, short waiting times can be a competitive advantage for health care providers. Finally, short-waiting times can contribute to a more effective system applied in health care. In this chapter, the impact of waiting times of patients are analyzed on all three levels based on quantitative and qualitative study carried out by the authors as well as on the foregoing literature review. The situation of patients and their requirements are shown, strategies to reduce waiting times are presented by also considering the role of information and communication technologies, and several relevant questions raised are answered.
Effect of Cryogenic Treated Electrodes on Sensitization in Resistance Spot Welding of Stainless Steel
Authors: Singh Rupinder , Sharma R.
Published: June 2016

The aim of this study is to investigate the effect of cryogenic treated electrodes on the sensitization of ‘304 SS’ in resistance spot welding (RSW). An approach to model sensitization based upon the weld properties like: hardness, tensile-shear strength (T-S), while RSW of 304SS has been proposed and applied. Relationship between hardness, T-S and other parameter has been deduced by using Taguchi L9 orthogonal array (OA). The results indicate that for sensitization; coolant flow rate (CFR), weld time and voltage contributes significantly in RSW of SS.
Investigations on Effect of Electrode Polarity on Machining Performance of Ti-5Al-2.5Sn Alloy Using Electric Discharge Machining Process

Published: June 2016

In electrical discharge machining (EDM) process, electrode polarity plays an important role during machining operation. This paper addresses the issues of EDM utilizing the positive and negative tool-electrode polarity to explore the effects on the performance criteria such as material removal rate (MRR), tool wear rate (TWR), surface roughness (SR) and micro-hardness during machining of Ti–5Al-2.5Sn (GradeVI) Ti alloy. The Ti-5Al-2.5Sn alloy was machined using copper-chromium electrode with positive and negative polarity by varying the peak current and pulse-on-time, while the pulse-off-time was kept constant. The result of study suggests that reverse polarity improves the MRR, TWR, SR while normal polarity improves the surface micro-hardness. The peak current has the maximum affect on machining performance for both types of polarities. Further the migration of different elements and formation of compounds on the machined surface was investigated using EDX and XRD analysis.
Experimental Investigations for Fabrication and Comparison of Fatigue Properties of an Open Cell Porous Regular Metallic Structure and with Inner Solid Core through Rapid Manufacturing
Authors: Singh Jatender Pal , Pandey Pulak M.
Published: June 2016

In this study parts having Open Cell Porous Regular Interconnected Metallic Structure (OCPRIMS) of cubic unit cell and OCPRIMS with inner solid core were fabricated through developed process of Rapid Manufacturing (RM) process. Two approaches were used to fabricate inner solid core i,e one by using metallic phosphor bronze powder and other by using solid phosphor bronze rod. The specimens were fabricated in accordance with ISO 3928: 1999 and subjected to tension-tension and compressive-compressive fatigue testing. The endurance limit of OCPRIMS with solid rod cored structure was found to be on the higher side in comparison to other types of specimens. The results of Scanning Electron Microscopy (SEM) and images of fractured surfaces showed the presence of voids, shrinkage cavities and pointed edges on the designed pores. They acted as stress raisers and facilitated crack initiation and propagation in the specimens.
Resident T Cells Are Unable To Control Herpes Simplex Virus-1 Activity in the Brain Ependymal Region during Latency

Published: June 2016

HSV type 1 (HSV-1) is one of the leading etiologies of sporadic viral encephalitis. Early antiviral intervention is crucial to the survival of herpes simplex encephalitis patients; however, many survivors suffer from long-term neurologic deficits. It is currently understood that HSV-1 establishes a latent infection within sensory peripheral neurons throughout the life of the host. However, the tissue residence of latent virus, other than in sensory neurons, and the potential pathogenic consequences of latency remain enigmatic. In the current study, we characterized the lytic and latent infection of HSV-1 in the CNS in comparison with the peripheral nervous system following ocular infection in mice. We used RT-PCR to detect latency-associated transcripts and HSV-1 lytic cycle genes within the brain stem, the ependyma (EP), containing the limbic and cortical areas, which also harbor neural progenitor cells, in comparison with the trigeminal ganglia. Unexpectedly, HSV-1 lytic genes, usually identified during acute infection, are uniquely expressed in the EP 60 d postinfection when animals are no longer suffering from encephalitis. An inflammatory response was also mounted in the EP by the maintenance of resident memory T cells. However, EP T cells were incapable of controlling HSV-1 infection ex vivo and secreted less IFN-γ, which correlated with expression of a variety of exhaustion-related inhibitory markers. Collectively, our data suggest that the persistent viral lytic gene expression during latency is the cause of the chronic inflammatory response leading to the exhaustion of the resident T cells in the EP.
