Dynamics and interactions of ibuprofen in cyclodextrin nanosponges by solid-state NMR spectroscopy
Authors: Ferro Monica , Castiglione Franca , Pastori Nadia , Punta Carlo , Melone Lucio , Panzeri Walter , Rossi Barbara , Trotta Francesco , Mele Andrea
Published: January 2017

Two different formulations of cyclodextrin nanosponges (CDNS), obtained by polycondensation of β-cyclodextrin with ethylenediaminetetraacetic acid dianhydride (EDTAn), were treated with aqueous solutions of ibuprofen sodium salt (IbuNa) affording hydrogels that, after lyophilisation, gave two solid CDNS-drug formulations. 1H fast MAS NMR and 13C CP-MAS NMR spectra showed that IbuNa was converted in situ into its acidic and dimeric form (IbuH) after freeze-drying. 13C CP-MAS NMR spectra also indicated that the structure of the nanosponge did not undergo changes upon drug loading compared to the unloaded system. However, the 13C NMR spectra collected under variable contact time cross-polarization (VCT-CP) conditions showed that the polymeric scaffold CDNS changed significantly its dynamic regime on passing from the empty CDNS to the drug-loaded CDNS, thus showing that the drug encapsulation can be seen as the formation of a real supramolecular aggregate rather than a conglomerate of two solid components. Finally, the structural features obtained from the different solid-state NMR approaches reported matched the information from powder X-ray diffraction profiles.
Mémoire et oubli dans l’institution : pertinence du travail de supervision
Authors: Bianchera Luciana , Cavicchioli Giorgio , Milano Fiorenza
Published: January 2017

Les auteurs présentent la dynamique inter-transférentielle dans un groupe de travail composé de travailleurs sociaux. Le contexte est observé lors d’interventions de supervision. Au cours d’une séance de supervision, une professionnelle présente une situation clinique à travers un récit. Le travail groupal de supervision a permis l’élaboration d’une série de processus psychiques et des vécus émotionnels correspondants chez les soignants. La situation groupale a été examinée à l’intérieur du contexte institutionnel, à travers le schéma de référence de la psychanalyse appliquée, en utilisant plus particulièrement la théorie de J. Bleger.
Narcissisme de couple et espace intermédiaire à l’épreuve de la psychose juvénile
Authors: Boudarse Khalid
Published: January 2017

Comment penser la psychose de l’adolescent en lien avec le narcissisme du couple parental ? L’auteur suppose que plus le narcissisme de couple (ou transnarcissisme) est assuré, plus l’espace intermédiaire est riche et moins le portage narcissique de l’adolescent est défaillant. Aborder le couple comme formation psychique nous amène à penser en termes de transnarcissisme et d’espace intermédiaire. En mettant l’accent sur le fonctionnement psychique du couple, l’auteur s’appuie sur deux cas cliniques pour aborder ces questions.
Le militantisme révolutionnaire à l’heure de la clandestinité dans les années 1968
Authors: Melchior Hugo
Published: January 2017

Désireux de voir l’ordre public restauré, après plus de dix jours de paralysie du pays, le général de Gaulle décida d’imposer par décret la dissolution de onze organisations d’extrême gauche. Or, contrairement à toutes les autres organisations révolutionnaires rendues illégales, la direction nationale du Parti communiste marxiste-léniniste de France fit le choix de ne pas renoncer au sigle PCMLF. Dès lors, commença pour l’organisation marxiste-léniniste et ses militants une période de clandestinité, au sens de maintien prolongé dans l’illégalité, qui provoqua la nécessaire dissimulation par les militants d’une partie ou de la totalité des activités politiques régulières maintenues, afin de se protéger de la répression étatique.
Des intellectuels français à la rencontre du Duce et du Führer
Authors: Saintin Alexandre
Published: January 2017

Au gré de leurs circulations dans l’Europe brune et noire, les intellectuels français produisent des récits variés où la rencontre de l’altérité politique interroge. Incarnant les nouveaux régimes, la figure du dictateur s’impose dans les narrations des voyageurs au point d’en devenir un incontournable. Voir cette figure, comprendre les raisons d’un succès, les déraisons d’une mystique nationale, mesurer les intentions d’un régime à l’égard de la France en s’adressant à sa tête « pensante », confier son admiration, faire valoir son expertise, devenir à son tour auteur, figure d’autorité pour avoir rencontré l’autorité en personne : telles sont les ambitions des intellectuels français partis à la rencontre des dictateurs fasciste et nazi.
Person-Centered Primary Care Strategies for Assessment of and Intervention for Aggressive Behaviors in Dementia
Authors: Desai Anand , Wharton Tracy , Struble Laura , Blazek Mary
Published: January 2017

With an increase in the number of individuals affected by dementia, it is imperative for health care providers to be well versed in the most effective ways to manage neuropsychiatric symptoms, such as aggression. Aggression can be particularly hard to manage because it creates risk of harm for formal and informal caregivers, and options for medical intervention are complex and situation dependent. Although multiple guidelines for management of aggression in dementia are available in the literature, their scope is widespread and suggested treatments often vary, making decision making difficult to navigate for busy clinicians. Using a composite case as a model, the current article provides guidelines that take outpatient providers through the steps needed to provide effective treatment for aggression in individuals with dementia. Shifting the current focal point of health care for aggressive dementia patients toward a more person-centered approach will have a positive impact on patient care. [

Context as Action in the Teaching of Statistical Concepts
Authors: Harth Helen
Published: February 2017

The teaching of statistics at university to non-majors is an under-research area of statistics education. This chapter investigates what characterizes the context of teaching statistics at tertiary level. To do this, the chapter takes an activity theory perspective to situate the teaching of statistics within the activity of learning. The data consists of observations of statistics lectures from one statistics for Psychologists module and interviews with the lecturer. The data was analyzed using activity theory as an analytical tool and theoretical perspective. As expected, context in this statistical module was about the scenario or story relating to a dataset used in problems, exercises or examples. In addition, the lecturer moved between multiple (or parallel) contexts with different, possibly conflicting rules, tools and communities. The findings add to the work on understanding context in learning statistics and provide insights into its complexity and multi-faceted nature.
Statistics in Journalism Practice and Higher Education
Authors: Lugo-Ocando Jairo A.
Published: February 2017

Drawing from comparative experiences in the United Kingdom and the United States, this chapter examines the issues and challenges of trying to teach statistics to journalism students. In so doing, it discusses the epistemological reasons why should journalism studies as a field incorporate statistics while arguing in favour of a re-examination of the overall curricula in British universities. The chapter deals with issues of resource, competences and abilities of those called to teach statistics in this area as well as the limitations and constrains in terms of resources and teaching materials. The chapter finally calls for an integrated approach in which statistics is not taught as a silo but instead embedded into the wider syllabus.
The FC Rad Diag(SA): Stretched, but still in step – Report on a Royal College observership
Authors: Pitcher Richard , De Vries Coert , Lockhat Zarina
Published: January 2017

A delegation of the College of Radiologists of the overarching Colleges of Medicine of South Africa observed the spring sitting of the Part 2B Examination of the Fellowship of the Royal College of Radiologists (FRCR) in London, in April 2016. Although the principal focus of the Observership was the Part 2B examination, the delegates also assessed broader aspects of the FRCR. This report presents an overview of current FRCR practices, including the findings of an independent review of the FRCR, and reflects on the implications for the South African Fellowship examination. The report is based on discussions with key Royal College role players, direct observation of the Part 2B examination and web-based documentation. It allows appreciation of the continued close alignment of the FC Rad Diag(SA) (Fellowship of the College of Radiologists of the Colleges of Medicine of South Africa) with the FRCR and highlights expected trends in the FC Rad Diag(SA). It also documents the increasing human resources required for successful conduct of examinations. It is hoped that the report will be of interest and relevance to the broad South African radiological community and to those contemplating specialist training in the discipline. It is trusted that it will encourage wider involvement of radiological and medical physics colleagues in the various FC Rad Diag(SA) examination processes.
Experiencing Hektor
Authors: Kozak Lynn
Published: January 2017

At the Iliad's climax, the great Trojan hero Hektor falls at the hands of Achilles. But who is Hektor? He has resonated with audiences as a tragic hero, great warrior, loyal husband and father, protector of a doomed city. Yet never has a major work sought to discover how these different aspects of Hektor’s character accumulate over the course of the narrative to create the devastating effect of his death.

This book documents the experience of Hektor through the Iliad’s serial narrative. Drawing on diverse tools from narratology, to cognitive science, but with a special focus on film character, television poetics, and performance practice, it examines how the mechanics of serial narrative construct the character of Hektor. How do we experience Hektor as the performer makes his way through the epic? How does the juxtaposition of scenes in multiple storylines contribute to character? How does the narrative work to manipulate our emotional response? How does our relationship to Hektor change over the course of the performance?

Lynn Kozak demonstrates this novel approach through a careful scene-by-scene breakdown and analysis of the Iliad, focusing especially on Hektor. In doing so, she challenges and destabilises popular and scholarly assumptions about both ancient epic and the Iliad’s ‘other’ hero.
Amplifying Islam in the European Soundscape
Authors: Arab Pooyan Tamimi
Published: January 2017

Public manifestations of Islam remain fiercely contested across the Global West. Studies to date have focused on the visual presence of Islam - the construction of mosques or the veiling of Muslim women. Amplifying Islam in the European Soundscape is the first book to add a sonic dimension to analyses of the politics of Islamic aesthetics in Europe.

Sound does not respect public/private boundaries, and people experience sound viscerally. As such, the public amplification of the azan, the call to prayer, offers a unique opportunity to understand what is at stake in debates over religious toleration and secularism. The Netherlands were among the first European countries to allow the amplification of the azan in the 1980s, and Pooyan Tamimi Arab explores this as a case study embedded in a broader history of Dutch religious pluralism.

The book offers a pointed critique of social theories that regard secularism as all-encompassing. While cultural forms of secularism exclude Muslim rights to public worship, Amplifying Islam in the European Soundscape argues that political and constitutional secularism also enables Muslim demands for amplifying calls to prayer. It traces how these exclusions and inclusions are effected through proposals for mosques, media debates, law and policy, but also in negotiations on the ground between residents, municipalities and mosques.
Corpus Linguistics and 17th-Century Prostitution
Authors: McEnery Anthony , Baker Helen
Published: January 2017

Corpus linguistics has much to offer history, being as both disciplines engage so heavily in analysis of large amounts of textual material.

This book demonstrates the opportunities for exploring corpus linguistics as a method in historiography and the humanities and social sciences more generally. Focussing on the topic of prostitution in 17th-century England, it shows how corpus methods can assist in social research, and can be used to deepen our understanding and comprehension.

McEnery and Baker draw principally on two sources – the newsbook Mercurius Fumigosis and the Early English Books Online Corpus. This scholarship on prostitution and the sex trade offers insight into the social position of women in history.
Menéndez contra Menéndez. Represión y resistencia de los discípulos de Menéndez Pidal ante la ofensiva intelectual tradicionalista de posguerra en la universidad española
Authors: Pallol Trigueros Rubén
Published: February 2017

A la altura de la década de 1930 Menéndez Pidal había logrado crear una sólida escuela de Filología e Historia en España que las nuevas autoridades académicas de la dictadura trataron de destruir a partir de 1939. Usando como bandera al otro Menéndez (Pelayo) trataron de controlar los puestos académicos claves y destruir los cimientos de una tradición liberal de pensamiento. Analizando las oposiciones a cátedras de posguerra, el texto retratará la represión a la que fueron sometidos los discípulos de Menéndez Pidal y las estrategias de las que se valieron para sobrevivir en el campo académico.
Medical Allocations to Persons with Special Needs during a Bioterrorism Event
Authors: Brannen Donald E , Branum Melissa , Pawani Sejal , Miller Sandy , Bowman Jeanne , Clare Tracy
Published: January 2017

After the bioterrorism-anthrax attacks of 2001, individual public health officials were tasked with planning population-wide medicine dispensing. This planning started with assumptions and then evaluations of seasonal immunization clinics. Research of the 2009 H1N1 pandemic-vaccination campaign showed that an adequately prepared public health system could have prevented over 16% of flu-associated hospitalizations. The 2011 ice storms revealed difficulties with sheltering medically fragile persons with disabilities. Later research showed that training and preparedness levels increased responders’ willingness to serve. Also, when triaging disaster survivors to general shelters, medical shelters, or mental health services; sorting to community mass care services improved up to 15% when past traumatic effects, personal care assistance, or service methodology were accounted for. The number of persons who are disabled and dependent on electric medical equipment are increasing. This current study compared the time it takes to dispense medication to two different cohorts: a general-population cohort (n=31) and a special-needs cohort (n=30). The cohort comprised entirely of persons with special needs took 4.1 compared to 2.48 minutes per person in a general population cohort (p=.057). A person with any special needs took 3.73 versus 2.43 minutes for a person with no special needs (p=.082). Modeling of service times per station and cohort type found significant delays at the medical station among persons in the general population who are pregnant (840 seconds, p=.002) and persons in the special needs cohort with a language barrier (750 seconds, p=.001).
Mobile Access to Clinical Information at the Point of Care
Authors: Mncube-Barnes Fatima M , Lee Ben , Esuruoso Olumuyiwa , Gona Phil N , Daphnis Stephane
Published: January 2017

Purpose: Librarians partnered with the Chief Resident and coordinators of the Internal Medicine residency program to assess how a formalized approach of introducing mobile access to clinical knowledge at the point of care enhanced medical practice. This three-year long study demonstrated that over time residents were able to adapt handheld computing with support on how the technology could facilitate successful completion of their work role-related tasks. Methods: Three cohorts of internal medicine residents were issued iPads at the beginning of their second year and trained in accessing institutional resources from the digital library. Pre- and post-intervention surveys were respectively administered at the beginning of the second year and end of the third year of training. Institutional technical and resource support were made available for each cohort. Pre- and post-intervention responses were compared using two sample methods and summarized through descriptive statistics. Results: 68 residents (38% women, mean age = 35.1, SD = 5.1 years) completed the pre-intervention survey questionnaires and 45 completed the post-intervention surveys. There were significant improvements in the residents’ level of computer experience, familiarity with medical information Apps, and appreciation for the electronic medical record. Additionally, residents preferred a highly capable computer system for clinical purposes and positively perceived the potential effects of computers and electronic medical record on medicine. Conclusion: Study findings suggested that institutions played a critical role in providing technology training to their resident physicians, especially in mobile access to clinical information at the point of care. The residents showed appreciation of iPads and library support that facilitated successful completion of their work role-related tasks. Replicating this study with a larger sample size derived from multiple sites is suggested for future studies that should also include mid-level healthcare professionals such as Physician Assistants and Advanced Nurse Practitioners.

A média de utilização do cateter totalmente implantado foi 303 dias, enquanto do cateter epicutâneo foi 55 dias, o término do tratamento é o principal motivo de retirada de ambos. A falta de preenchimento de informações nas fichas foi limitador desta pesquisa. Concluímos que estes dispositivos são eficazes e seguros para tratamento quimioterápico.
A importância da articulação teoria e prática nos percursos formativos dos professores de história
Authors: Marques Janote Pires , Miranda Augusto Ridson De Araújo
Published: February 2017

Este artigo visa problematizar possibilidades para relações entre teoria e prática na formação e nas práticas dos professores de História, suscitadas a partir de reflexões acerca de nossas experiências docentes de professores do ensino básico e superior, além de pesquisadores do Ensino de História. A metodologia empregada é de análise bibliográfica e documental, visando articular os percursos formativos, saberes e práticas na formação do historiador-professor. Partimos da compreensão de formação docente como percurso formativo (TARDIF (2014)), em que os saberes docentes mobilizados na profissão docente são adquiridos ao longo de uma trajetória de vida. Com base nesta compreensão, partimos dos estudos em Educação Histórica (LEE, 2001; BARCA, 2001) e das reflexões historiográficas da Didática da História (RÜSEN, 2006) como possibilidades de constituição de saberes que articulem teoria e prática (saberes da ação pedagógica, nos dizeres de Gauthier et al (1998)). Além dos saberes da ação pedagógica, questionamos o papel das legislações educacionais na promoção da articulação teoria-prática da formação dos professores de História, almejada nos discursos das políticas educacionais. Entendemos a relevância deste esforço reflexivo nos estudos em Educação, com ênfase nos de Formação de Professores de História (FONSECA, 2012)), mas igualmente nos estudos históricos, em que a articulação teoria-prática faça parte do métier do historiador (CERTEAU, 2009), também professor.
Beckett’s Cruel Lover
Authors: Mohammed Mustafa Ahmad
Published: January 2017

Samuel Beckett wrote Eh Joe for television production in 1965. He wrote this bleak play, for his friend the actor Jack MacGowran. The first production of the play was in Germany at Suddenscher Rundfunk Stuttgart on 13 April 1966, and was directed by Samuel Beckett. In both his novels and plays, Beckett paid special attention to human relationships. In his major plays cruelty is the pivot theme. In Eh Joe, Joe a solitary figure is trying to secure himself in his room in an attempt to run away from Voice who keeps reminding him of his cruelty to the girl who loves him. But the past comes to him in a form of Woman’s Voice to remind him of his selfishness and cruelty. Voice focuses on Joe’s cruelty in his relationships and continues hammering him till the end of the play. In less than fifteen minutes Beckett successfully portrays Joe’s selfishness, indifference and cruelty to women who love him.

The Long-Run Performance of U.S. Bidding Firms in the Post M&A Period: The Impact of Bid Type, Payment Method and Industry Specialisation
Authors: Giannopoulos George , Holt Andrew , Khansalar Ehsan , Mogoya Patrick
Published: January 2017

This study investigates how mergers and acquisitions (M&A) affect the wealth of shareholders of public firms in the United States (U.S). More specifically, it investigates whether the nature of the bid, the payment method used, and the type of M&A have implications for shareholders of U.S bidding firms. The study analyses 352 mergers and acquisitions in the U.S during the period 1999-2008, and its results indicate that bidding firms suffer significant negative buy-and-hold abnormal returns in the three years period after a M&A announcement. The results also suggest that, in the long-run, hostile bids and cash-financed bidders outperform friendly bids and stock-funded bidders, respectively. Furthermore, the study also finds that in the long-run bidder firms that focus on industry specialisation within their M&A targets significantly outperform firms that adopt a more diversified strategy. The analysis also investigates the effects of M&A specialisation/diversification in six different sectors, and finds that specialised bidders outperform diversified bidders in four sectors: consumer & basic materials, energy & utilities, communications and technology. Furthermore, bidder firms in the financial services sector perform significantly better when diversifying into other sectors, while the performance of bidder firms in the industrial sector appears unaffected by the degree of M&A specialisation or diversification.
Methods and Tools to Reorganise the Governance in the Italian Healthcare Companies
Authors: Gervasio Daniele , Amaduzzi Andrea , Montani Damiano
Published: January 2017

This paper is a first analysis of the tools required to convert the fiscal data gathered from the management control systems into official guidelines for a long-lasting healthcare governance.This paper proposes some reflections about the peculiarity of the cost monitoring and management systems whose configuration and effectiveness must take into consideration the nature of the information requirement of the management processes addressee.The innovative aspect is to convey all the potential information contained in the cost monitoring systems. In fact, the information represents the subjective aspect, in other words what the reader ‘understands’ and perceives.These tools may not be analysed from a mere technical point of view, instead they must be considered as essential means to manage complex corporate systems.Using Amaduzzi’s theories and following an exploratory approach, this paper proposes some considerations about the tools required to convert the acts of management into (economic) values. Then, these values will convert into acts of management thanks to their capability to meet the information requirement of the governance stakeholders.The analysis carried out highlights the information requirement to satisfy through a series of monitoring and management tools, in order to find organisational and management solutions that are able to combine the need to rationalise the healthcare expenditure and to improve the quality and pertinence of health care services.
Wheat Bran Dietary Fiber: Promising Source of Prebiotics with Antioxidant Potential
Authors: Gunenc Aynur , Alswiti Christina , Hosseinian Farah
Published: January 2017

The potential of wheat bran (WB) addition as a prebiotic source were demonstrated using yogurt with probiotics (Lactobacillus acidophilus and Bifidobacterium lactis). Yogurts (with 4% WB) were significantly (P < 0.05) different in total bacterial counts (9.1 log CFU/mL), and total titratable acidity % (TTA, 1.4%) compared to controls during 28 days cold storage (4°C). Additionally, WB-total dietary fiber contents and their bound phenolic profiles were investigated as well as the antioxidant activity of WB-water extractable polysaccharides (WEP) was studied. HPLC analysis of alkaline hydrolyzed DF fractions showed that insoluble DF had higher phenolic acids (84.2%) content than soluble DF (15.8%). Also, crude-WEP showed stronger antioxidant activity compared to purified-WEP with an ORAC of 71.88 and 52.48 µmol TE/g, respectively. Here we demonstrate WB has potentials as a source of prebiotics, which may have the potentials for functional foods and nutraceutical applications.
The Significance of an Antenna for Jamming Resistance of a GPS Receiver
Authors: Felski Andrzej , Gortad Marta
Published: January 2017

At present jamming is considered one of the main threats to a GPS receiver’s user, both in dynamic and stationary conditions, and especially regarding telecommunication synchronization. Threats stemming from the use of cheap jammers, more and more commonly referred to as Personal Protecting Devices, available on the Internet, are especially dangerous. Despite the formal ban on using them, there is evidence that they are in common use. Therefore the problem which has hitherto been considered marginal needs to be urgently investigated. Reports dealing with investigations on jamming focus mostly on analyses of effects of various jammers on receivers. This article presents part of the results of experiments focused on the effects and it shows that the effects of jamming when the same device is used depend on both the receiver and the antenna it employs.

A “Close” Look at Linear Approximations
Authors: Kerrigan John
Published: January 2017

Approximation is a concept that underpins many big ideas in calculus. Students approximate the slope of a tangent line using secant-line slopes and eventually evaluate limits of those approximations. Linear approximation has uses in differential calculus. To help my students understand linear approximation, I adapted an activity from the Instructor's Guide for Stewart's Calculus (Shaw 2015). Students construct multiple representations of four functions and analyze each function's behavior near the origin using Desmos® (Desmos Graphing Calculator 2016) or similar technology, for better visualization.
Thank You for the Music: Musical Activities as Therapy for Autistic Children
Authors: Gawlick Natasza
Published: January 2017

Music therapy, developed over the years by numerous musicians and educators, such as Carl Orff, Jacques-Dalcroze, and Kodaly, have proven to stimulate social interaction, improve selective attention and aid in numerous other developmental milestones. These findings are not only important for parents and school curricula, but also have profound meaning for children with autism. Numerous studies, including work done by Koelsch, as well as Winsler, Ducenne, and Koury, found that children who participated in a music and movement program developed greater self-regulation skills, such as private speech, showed greater improvement in coordination, and fostered positive social interaction between researcher and subject. Autistic children who were exposed to music therapy held eye contact longer, engaged in dialogue, and reduced negative behaviors such as head-banging, avoidance, or self-stimulatory behaviors. Diverse methods of music therapy, including playing instruments, listening to sounds, and other musical activities, could greatly improve the social, emotional, and educational development of autistic children.
Size of Sclerosing Foams Prepared by Ultrasound, Mechanical Agitation, and the Handmade Tessari Method for Treatment of Varicose Veins
Authors: Critello Costantino Davide , Fiorillo Antonino S. , Matula Thomas J.
Published: January 2017

Objectives

Sclerotherapy is a therapeutic method used in the treatment of varicose veins and works by occluding damaged blood vessels with a chemical solution. Foam sclerotherapy is an attractive treatment because the results are more effective than those obtained by using liquid sclerosants. However, serious neurologic complications, which are likely related to air embolism, have been reported after treatment with foams generated by the handmade method (Tessari technique) most often used clinically. We present an alternative ultrasonic technique for preparation of sclerosing foams to treat varicose veins.

Methods

Three methods of foam generation were compared: ultrasound, mechanical agitation, and Tessari techniques.

Results

Optical microscopic analyses showed that low‐frequency ultrasound can generate foams with smaller bubble distributions compared to those produced by handmade and mechanical agitation methods: 98% of the bubble population was less than 55 ± 10 μm for sonicated foams (mean ± SD, 19 ± 1.8 μm; maximum bubble size, <138.3 ± 32.5 μm), 196.7 ± 38.2 μm for mechanically agitated foams (mean, 37.1 ± 10.6 μm; maximum bubble size, <350 ± 70.9 μm), and 211.7 ± 20.8 μm for handmade foams (mean, 30.8 ± 3.8 μm; maximum bubble size, <445 ± 32.8 μm).

Conclusions

Low‐frequency ultrasonic foam generation yields smaller bubbles and more uniform size distributions than other investigated methods. These properties may reduce serious adverse events reported for sclerotherapy of varicose veins, increasing the safety of foam treatment.
The role of plasma slowdown in the generation of Rhea's Alfvén wings
Authors: Khurana Krishan K. , Fatemi Shahab , Lindkvist Jesper , Roussos Elias , Krupp Norbert , Holmström Mats , Russell Christopher T. , Dougherty Michele K.
Published: February 2017

Alfvén wings are known to form when a conducting or mass‐loading object slows down a flowing plasma in its vicinity. Alfvén wings are not expected to be generated when an inert moon such as Rhea interacts with Saturn's magnetosphere, where the plasma impacting the moon is absorbed and the magnetic flux passes unimpeded through the moon. However, in two close polar passes of Rhea, Cassini clearly observed magnetic field signatures consistent with Alfvén wings. In addition, observations from a high‐inclination flyby (Distance > 100 RRh) of Rhea on 3 June 2010 showed that the Alfvén wings continue to propagate away from Rhea even at this large distance. We have performed three‐dimensional hybrid simulations of Rhea's interaction with Saturn's magnetosphere which show that the wake refilling process generates a plasma density gradient directed in the direction of corotating plasma. The resulting plasma pressure gradient exerts a force directed toward Rhea and slows down the plasma streaming into the wake along field lines. As on the same field lines, outside of the wake, the plasma continues to move close to its full speed, this differential motion of plasma bends the magnetic flux tubes, generating Alfvén wings in the wake. The current system excited by the Alfvén wings transfers momentum to the wake plasma extracting it from plasma outside the wake. Our work demonstrates that Alfvén wings can be excited even when a moon does not possess a conducting exosphere.
F3 layer development during quiet and disturbed periods as observed at conjugate locations in Brazil: The role of the meridional wind
Authors: Batista Inez S. , Candido C. M. N. , Souza J. R. , Abdu M. A. , de Araujo R. C. , Resende L. C. A. , Santos A. M.
Published: February 2017

In this work we use ionospheric data from two low‐latitude stations located north and south of the geomagnetic equator, at approximately the same magnetic longitude, in order to study the occurrence of the F3 layer. The location of the stations being at almost geomagnetically conjugate points is such that the effects of the electric field/vertical plasma drift and diffusion will be almost symmetric around the magnetic equator. Under this configuration it is possible to deduce the effect of meridional wind in the F3 layer occurrence. Our results show that during the December solstice the layer will be present at the Southern Hemisphere (SH) location in 97% of the days and in the Northern Hemisphere (NH) location in only 4% of the days. In the June solstice the situation is reversed with the occurrence in the NH being 82% and 16% in the SH. For the March equinox the occurrence is low at both locations (4% in NH and 7% in SH), being mainly present during magnetically disturbed periods. The analysis of the effective meridional wind based on the Horizontal Wind Model and on the asymmetry of the F layer peak height observed at the two locations confirms the ubiquitous role of the wind in the F3 layer formation and/or persistence during both quiet and disturbed periods. The B0 parameter, that is a measure of the thickness of the bottomside F region profile, revealed to be a good proxy for the F3 layer occurrence.

Recent regulatory policies in East Asia reduce ozone precursors, but these changes are spatially and temporally nonuniform. This study investigates variations in the long‐term trends of tropospheric NO2, HCHO, and HCHO/NO2 ratios to diagnose ozone sensitivity to changes in NOx and volatile organic compound using the Ozone Monitoring Instrument (OMI). Using an adaptive‐degree polynomial filter, we identify extremums of time series of NO2 to determine when and how NO2 change. Due to the regulations in China, trends which were predominantly upward turned downward. The years undergoing these changes primarily happened in 2011 and 2012. OMI column densities, however, suggest that NOx sources in South Korea, the Pearl River Delta (PRD), Taiwan, and Japan have not consistently decreased. Specifically, as Chinese exports of NO2 started subsiding, increasing trends in NO2 columns over several Korean cities, including Seoul, become evident. To quantify the changes in NOx emissions from summertime 2010 to 2014, we conduct a 3D‐Var inverse modeling using a regional model with MIX‐Asia inventory and estimate NOx emissions (in 2010 and 2014) for the PRD (1.6 and 1.5 Gg/d), the Yangtze River Delta (3.9 and 3.0 Gg/d), north China (15.6 and 14.3 Gg/d), South Korea (1.6 and 1.5 Gg/d), and Japan (2.7 and 2.6 Gg/d). OMI HCHO shows upward trends in East Asia resulting from anthropogenic effects; however, the magnitudes are negative in the PRD, Japan, North Korea, and Taiwan. OMI HCHO/NO2 ratios reveal that while South Korea, Japan, and the south of China have undergone toward more NOx‐sensitive regime, areas around the Bohai Sea have become more NOx saturated.

Published: February 2017

Fourier analysis is applied to time domain return stroke luminosity signals to calculate the phase and group velocities and the amplitude of the luminosity signals as a function of frequency measured between 4 m and 115 m during 12 triggered lightning strokes. We show that pairs of time domain luminosity signals measured at different heights can be interpreted as the input and the output of a system whose frequency domain transfer function can be determined from the measured time domain signals. From the frequency domain transfer function phase we find the phase and group velocities, and luminosity amplitude as a function of triggered lightning channel height and signal frequency ranging from 50 kHz to 300 kHz. We show that higher‐frequency luminosity components propagate faster than the lower frequency components and that higher‐frequency luminosity components attenuate more rapidly than lower frequency components. Finally, we calculate time domain return stroke velocities as a function of channel height using two time delay techniques: (1) measurement at the 20% amplitude level and (2) cross correlation.

Nanoparticles possess the potential to revolutionize cancer diagnosis and therapy. The ideal theranostic nanoplatform should own long system circulation and active cancer targeting. Additionally, it should be nontoxic and invisible to the immune system. Here, the authors fabricate an all‐in‐one nanoplatform possessed with these properties for personalized cancer theranostics. Platelet‐derived vesicles (PLT‐vesicles) along with their membrane proteins are collected from mice blood and then coated onto Fe3O4 magnetic nanoparticles (MNs). The resulting core–shell PLT‐MNs, which inherit the long circulation and cancer targeting capabilities from the PLT membrane shell and the magnetic and optical absorption properties from the MN core, are finally injected back into the donor mice for enhanced tumor magnetic resonance imaging (MRI) and photothermal therapy (PTT). Meanwhile, it is found that the PTT treatment impels PLT‐MNs targeting to the PTT sites (i.e., tumor sites), and exactly, in turn, the enhanced targeting of PLT‐MNs to tumor sites can improve the PTT effects. In addition, since the PLT membrane coating is obtained from the mice and finally injected into the same mice, PLT‐MNs exhibit stellar immune compatibility. The work presented here provides a new angle on the design of biomimetic nanoparticles for personalized diagnosis and therapy of various diseases.

Developing a feasible way to prepare highly dispersed heterometallic nanoparticles incorporated in porous carbon composites is of significant importance for multifunctional materials. In this work, heterometallic γ‐Fe2O3 and GdPO4 nanoparticles that are incorporated in ordered mesoporous carbon composites are facilely prepared by a one‐pot in situ method using a Wells–Dawson‐like cluster of [Fe6Gd6(μ3‐O)2(CO3)(O3PPh)6(O2C

Carbon‐bridged bis(aminoaryl) oligo(para‐phenylenevinylene)s have been prepared and their optical, electrochemical, and structural properties analyzed. Their radical cations are class III and class II mixed‐valence systems, depending on the molecular size, and they show electronic couplings which are among the largest for the self‐exchange reaction of purely organic molecules. In their dication states, the antiferromagnetic coupling is progressively tuned with size from quinoidal closed‐shell to open‐shell biradicals. The data prove that the electronic coupling in the radical cations and the singlet–triplet gap in the dications show similar small attenuation factors, thus allowing charge/spin transfer over rather large distances.

Published: February 2017

Small‐molecule organic fluorophores spectrally active in the 800–950 nm region are sought‐after for their broad potential in biomedical and material applications. We have developed a new family of brightly fluorescent dyes (ECX) to meet this challenge. ECX dyes are transparent to the visible region, while strongly absorbing in the NIR region at approximately 880 nm. They emit at around 915 nm with a fluorescence quantum yield up to 13.3 %. ECX dyes exhibit high chemostability, high photostability, and low tendency to aggregate. Other merits of ECX dyes include low degree of solvatochromism and facile post‐synthetic derivatization. ECX dyes potentially make available the 800–950 nm region for spectroscopic and microscopic applications and are also expected to find broad material applications.
A Personal Construct Psychology Based Investigation Into A Product Service System For Renting Pushchairs To Consumers
Authors: Catulli Maurizio , Reed Nick
Published: February 2017

This paper explores how consumers construe a product service system (PSS) for the supply of pushchairs. A PSS is a system of products, services, networks of actors and supporting infrastructure designed to be more sustainable than traditional business models. PSSs face an implementation challenge in consumer markets, and this case based research explores some reasons for this. The study applies personal construct psychology (in particular, the repertory grid technique), which has not previously been used in relation to researching PSSs.

Results suggest that a PSS might be difficult to implement in relation to pushchairs. Renting pre‐used equipment may meet resistance because of a perceived risk that acquisition by this means might endanger infants. Participants in the study construed buying new products from specialist infant product shops as being the best way of acquiring them. Accordingly, PSS providers may, for instance, have to implement certified quality assurance processes in order to reassure consumers. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment
