"Sebastian Bachs Choralbuch" in Rochester, NY?
Authors: Schulze Hans-Joachim
Published: September 2020

Drei Manuskripte aus der Sammlung des Thomasschul-Alumnus und späteren -Rektors Karl August Thieme (1721-1795) werden in Bezug zu Bach gesetzt. Sie enthalten das Pedal-Exercitium BWV 598, ein Handbuch mit Generalbassübungen von 1738 und ein Choralbuch, das sich heute in Rochester, N. Y. befindet. Alle drei Quellen sind von zweifelhafter Authentizität. Die Darstellung ihrer Herkunft führt zu einer Gruppe von Dresdner Vertretern der romantischen Bewegung im Zusammenhang mit dem Freischütz-Librettisten Johann Friedrich Kind.

"Nun ist das Heil und die Kraft" BWV 50: Doppelchörigkeit, Datierung und Bestimmung
Authors: Scheide William H.
Published: September 2020

Der einzelne Kantatensatz BWV 50, der nur in Kopien nach 1750 erhalten blieb, war wahrscheinlich in einer Michaeliskantate für 1723 enthalten. Die Doppelchorstruktur ist offensichtlich das Ergebnis einer Revision aus einer anderen Hand; die Originalbesetzung lässt sich als Sopran, Alt I und II, Tenor und Bass bestimmen.

Eine Michaeliskantate als Parodievorlage für den sechsten Teil des Bachschen Weihnachts-Oratoriums?
Authors: Glöckner Andreas
Published: September 2020

Johann Sebastian Bachs 'Weihnachts-Oratorium' gehört zu den Werken, die überwiegend weltliche Gelegenheitsmusiken zur Vorlage haben. Der sechste Teil basiert mit Ausnahme von vier neu komponierten Sätzen hingegen auf einer vollständigen Kirchenkantate. Von dieser verschollenen Kantate sind vier Stimmendubletten (Violine I, II, Continuo, Organo) erhalten, da sie Bach mit geringfügigen Änderungen im Aufführungsmaterial des 'Weihnachts-Oratoriums' wieder verwendete. Die offensichtlich im Herbst 1734 geschriebenen Stimmen gehören allem Anschein nach zu einer am 29. September 1734 aufgeführten Michaeliskantate, die dem hypothetischen 5. Kantatenjahrgang Bachs zuzuordnen ist. (Autor, Quelle: Bibliographie des Musikschrifttums online)
Johann Sebastian Bachs dritter Leipziger Kantatenjahrgang und die Meininger "Sonntags- und Fest-Andachten" von 1719
Authors: Schulze Hans-Joachim
Published: September 2020

Sieben Kirchenkantaten Johann Sebastian Bachs von 1726 gehen auf Texte zurück, die erstmals 1704 in Meiningen als 'Sonn- und Fest-Andachten' im Druck erschienen waren. Einige Textvarianten belegen, dass dem Thomaskantor offenbar die dritte Auflage von 1719 zur Verfügung stand. (Autor, Quelle: Bibliographie des Musikschrifttums online)
Schooling, work and house life: women’s triple shifts in times of a global health crisis
Authors: Joiko Sara
Published: September 2020

This contribution aims to reflect from first-person accounts the impact that the school closure mitigation policy in England and Chile have had on women. The main motivation for writing this reflective piece is to present the views of women who are experiencing this educational policy in times of a global health crisis. This is important because their views have been apparently ignored by the two governments.
Gender differences in research samples of family carers of adults with cancer: a systematic review
Authors: Young Jenny , Kyle Richard G. , Sun Angela
Published: September 2020

Rising global demand for informal care makes it increasingly important to have a comprehensive understanding of carers’ experiences. However, research is thought to be skewed towards women’s experience, leading some to call men ‘forgotten carers’. A systematic review following Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines was conducted to assess the gender balance of study samples of family carers of someone living with cancer. A total of 82 articles involving 14,352 participants were reviewed. Overall, 35.5 per cent of participants were men and 64.5 per cent were women. Researchers should seek to overcome barriers to men’s participation in carer research in order to ensure the experiences of male and female carers are recognised through research.

Nonvolatile magneto-optical switches integrated with a magnet stripe array
Authors: Murai Toshiya , Shoji Yuya , Nishiyama Nobuhiko , Mizumoto Tetsuya
Published: September 2020

Nonvolatile optical switches are promising components for low-power photonic integrated circuits with multiple functionalities. In this study, we experimentally demonstrate magneto-optical switches integrated with a magnet array. Optical switches in both microring and Mach–Zehnder configurations are fabricated on a high-quality single-crystalline magneto-optical material Ce:YIG. The switched state is alternated by a current-induced magnetic field from an integrated electromagnet and remained without any external power supply owing to the nonvolatile magnetization of thin-film magnets. Subsequently, the arbitrary level control of optical transmission is demonstrated by changing the magnetization state of integrated thin-film magnets with a current applied in the microring gate switch, and a maximum switching ratio over 25 dB is achieved in the Mach–Zehnder switch. The latching operation is presented with a 1-µs pulsed voltage.
Tunable dual plasmon-induced transparency based on a monolayer graphene metamaterial and its terahertz sensing performance
Authors: Ge JiaHao , You Chenglong , Feng He , Li Xiaoman , Wang Mei , Dong Lifeng , Veronis Georgios , Yun Maojin
Published: September 2020

In this paper, tunable dual plasmon-induced transparency (PIT) is achieved by using a monolayer graphene metamaterial in the terahertz region, which consists of two graphene strips of different sizes and a graphene ring. As the dual PIT effect is induced by the destructive interference between the two quasi-dark modes and the bright mode, we propose a four-level plasmonic system based on the linearly coupled Lorentzian oscillators to explain the mechanism behind the dual PIT. It is proved that the theoretical results agree well with the simulation results. Most importantly, the sensing properties of the designed device have been investigated in detail and we found that it can exhibit high sensitivities and figure of merit (FOM). Furthermore, the dual PIT windows can be effectively modulated by changing the Fermi energy of the graphene layer and the angle of incidence. Thus, the proposed graphene-based metamaterial can hold wide applications for switches, modulators, and multi-band refractive index sensors in the terahertz region.
Details of the topological state transition induced by gradually increased disorder in photonic Chern insulators
Authors: Yang Bing , Zhang Hongfang , Shi Qiang , Wu Tong , Ma Yong , Lv Zengtao , Xiao Xia , Dong Ruixin , Yan Xunling , Zhang Xiangdong
Published: September 2020

Using two well-defined empirical parameters, we numerically investigate the details of the disorder-induced topological state transition (TST) in photonic Chern insulators composed of two-dimensional magnetic photonic crystals (MPCs). The TST undergoes a gradual process, accompanied with some interesting phenomena as the disorder of rod positions in MPCs increases gradually. This kind of TST is determined by the competition among the topologically protected edge state, disorder-induced wave localizations and bulk states in the system. More interestingly, the disorder-induced wave localizations almost have no influence on the one-way propagation of the original photonic topological states (PTSs), and the unidirectional nature of the PTSs at the edge area can survive even when the bulk states arise at stronger disorders. Our results provide detailed demonstrations for the deep understanding of fundamental physics underlying topology and disorder and are also of practical significance in device fabrication with PTSs.
Toy model of second harmonic generation due to structuring of centrosymmetric films
Authors: Xu Jie , Plum Eric , Savinov Vassili
Published: September 2020

We show how structuring of matter can lead to second order optical nonlinearity. Coulomb interactions involving bound electrons cause a nonlinear optical response at boundaries. We demonstrate that second order nonlinearity is proportional to the perimeter of a planar structure cut from a centrosymmetric lattice of harmonic oscillators. This proportionality and our model can instruct the design of dielectric nonlinear particles, surfaces and metamaterials for optical second harmonic generation.
Flexible tuning of nonlinear non-diffracting array beams using wavelengths and angles
Authors: Liu Dongmei , Zhang Yong , Hu Xiaopeng , Han Peng , Gu Min , Xiao Min
Published: September 2020

We present a simple method to enable flexible tuning of non-diffracting beams in a two-dimensional nonlinear photonic crystal, based on the interference of two or more non-collinear second-harmonic beams. By manipulating the wavelengths of the beams and the angle of incidence of the fundamental wave, the arbitrary period and propagation length, as well as the wavelength of the generated nonlinear non-diffracting array beams, can be tuned flexibly. These light beams can trap and manipulate multiple particles, create new forms of optical imaging systems, and act within nonlinear devices to bring novel functionalities to integrated optics.

Authors: Singh Amit Kumar , Bhakat Champak , Kumari Tripti , Mandal Dilip Kumar , Chatterjee Anupam , Karunakaran Muthupalani , Dutta Tapas Kumar
Published: September 2020

Background and Aim: Alpha-tocopherol supplementation influences milk yield, milk quality, and udder health of dairy cows, which needs to be investigated for Jersey crossbred cows at hot-humid climate. Therefore, the present study was framed with an objective to study the effect of pre and postpartum Alpha-tocopherol supplementation on milk yield, milk quality, and udder health status of Jersey crossbred cows at tropical climate.

Materials and Methods: For this study, 19 similar parity, body condition score, and production level dairy animals were separated randomly into three groups, namely, Control, T1 and T2. Control group (no supplementation) was compared with two treatment groups, namely, T1 and T2. Supplementation of Alpha-tocopherol was done in concentrate fed to the animals (at 1 g/cow/day) 30 days prepartum to 30 days postpartum in T1 and 30 days prepartum to 60 days postpartum in T2 groups. Observations were taken for different parameters up to 5 months of lactation.

Results: Statistically analyzed data revealed that overall significantly (p<0.01) more milk production was found in T2, followed by T1 than the control group. Overall significantly (p<0.01) lower somatic cell counts and modified California mastitis tests were recorded in T2, followed by T1 than the control group. Overall significantly (p<0.01), better milk quality in terms of methylene blue reduction test was found in T2, followed by T1 than control groups. Differences in the milk composition of all three groups were non-significant (p>0.05).

Conclusion: Supplementation of Alpha-tocopherol during prepartum to initial lactation period may enhance milk yield, milk quality, and udder health status of Jersey crossbred cows at the tropical lower Gangetic region.
Reflexiones sobre la dimensión transnacional de la literatura contemporánea en Italia y en Europa
Authors: Sinopoli Franca , Ansó Valeria , Franzoso Marco
Published: September 2020

El objetivo de este artículo es reflejar la dimensión transnacional de muchos autores contemporáneos en Italia y dentro del marco del contexto europeo. El transnacionalismo asigna un rol fundamental a la construcción de una imaginación transfronteriza o híbrida, en diferentes niveles culturales y counicacionales, por ejemplo alentando la atención a aquellas producciones en campos literarios, cinematográfico, artísticos que serían impensables si confiamos en el concepto tradicional de espacio donde la geografía física, cultural, política y social coinciden perfectamente. El paradigma del transnacionalismo también echa luz a las producciones de autores literarios contemporáneos que tienen backgrounds multiculturales y multilingüísticos, viven y operan en un contexto nacional específico o, en diferentes períodos, se mueven de una nación a otra, o incluso siguen trayectorias intercontinentales.
Tipos y lugares de la enfermedad en la obra de Giuseppe Bonaviri
Authors: González Martín Vicente
Published: September 2020

La temática de la enfermedad en la historia de la literatura en general e italiana en particular tiene una larga historia, porque está radicada en la parte más profunda del ser humano desde el nacimiento hasta la muerte y condiciona, en muchos casos el recorrido vital de un escritor. Es el caso de Giuseppe Bonaviri, nacido en Mineo en 1924 y muerto en Frosinone en el 2009. Escritor siciliano amante de su tierra, de su familia y de sus amigos, fue una persona de frágil constitución física. Quizá por esta razón y por su profesión de médico, la enfermedad acompaña siempre al escritor siciliano en su vida y en su literatura y su lenguaje poético se nutrirá abundantemente de los materiales que la enfermedad y la medicina le ofrecen.
Emigrar a Europa y escribir ficción. Los casos de Amara Lakhous y Gunter Silva Passuni
Authors: Magnani Ilaria
Published: September 2020

El trabajo se propone observar las obras de Amara Lakhous y Gunter Silva Passuni, intelectuales —argelino el primero y peruano el segundo— que comparten la decisión de vivir fuera de su propio país, habiendo elegido Europa, Italia y Gran Bretaña respectivamente. Su producción encara la experiencia del desarraigo y la condición del migrante volviéndola un espacio desde donde mirar a la nación de llegada, sus habitantes y capas sociales, haciendo hincapié en las múltiples contradicciones de este mundo. Una operación que subvierte —al menos simbólica, si no materialmente— la marginalidad del migrante y pone en entredicho la doble ausencia que el sociólogo franco–argelino indicó como dramática condición de todo trabajador migrante.

No se ve nada
Authors: Dubor Françoise , Zenarruza de Clément Silvia
Published: September 2020

El texto del escritor francés Pierre Michon, titulado Les Onze (Los once) permite considerar cómo se cruzan los regímenes de representación en ese texto, que son tan variados como ricos: literario, teatral, pictórico, museístico, histórico. Se trata de un cuadro que representa el Comité de Salvación Pública, bajo el Terror, durante la Revolución francesa. Pero el principio de este texto es su confrontación a lo irrepresentable, de allí una multiplicidad de estrategias para perfilar esta representación aporética. La manera en que los diversos regímenes de representación se responden, se completan, compiten entre sí, o se repiten, conduce a una reflexión sobre la manera en que el sentido se construye y evoluciona según el régimen de representación elegido, es decir, según su soporte. En definitiva, parecería que la representación fuese una imagen separada de todo objeto, de la que se trata de comprender el sentido y la función.
La transposición de códigos cinematográficos al cuento: un ejemplo de Ignacio Aldecoa
Authors: Hermosilla Álvarez Maria Ángeles
Published: September 2020

Aunque la relación entre el cine y la literatura ha sido siempre muy estrecha, el estudio comparatista de ambos sistemas de signos, que ha sido muy fructífero en la cuestión de las adaptaciones cinematográficas de novelas o cuentos, apenas se ha desarrollado en el caso de la impronta que el cine ha dejado en obras literarias concretas. Con tal fin, en nuestro trabajo trataremos de mostrar cómo las categorías narratológicas del tiempo, el espacio y los personajes reciben, en el relato de Aldecoa, el influjo del discurso fílmico.
Política y escritura. Más allá de la política de la literatura de Jacques Rancière
Authors: Martínez Olguín Juan José
Published: September 2020

A lo largo del siguiente trabajo intentaremos estudiar la relación entre política y escritura a partir de lo que Rancière denomina en sus textos una política de la literatura. Para ello, postularemos la hipótesis siguiente: que el modo a través del cual el autor concibe esta política de la literatura se mantiene en las fronteras de un pensamiento logocéntrico sobre la dimensión política de la escritura. El planteo de esta hipótesis involucrará, por lo tanto, dos momentos: en una  primera parte desarrollaremos lo que Rancière entiende bajo la expresión «política de la literatura», para luego mostrar los límites de esta fórmula contrastándola con lo que identificaremos, apoyándonos en trabajos previos de nuestra autoría y en algunos textos claves de Nancy y Derrida, como una política de la escritura desde la perspectiva de una política de la sensibilidad.

Comprensión de la representatividad y variabilidad muestral por estudiantes de Educación Secundaria
Authors: Begué Nuria , Batanero Carmen , Gea María Magdalena , Beltrán–Pellicer Pablo
Published: September 2020

El objetivo del trabajo fue analizar la mejora con el curso escolar de la comprensión de la representatividad y variabilidad muestral en estudiantes de secundaria. Para ello se analizan las respuestas dadas por una muestra de 536 estudiantes de tres cursos (segundo y cuarto curso de Educación Secundaria Obligatoria y segundo curso de Bachillerato) a una tarea en que se piden cuatro valores de una distribución binomial. Se analizan la media y rango de dichos valores, que constituyen una muestra de cuatro resultados de la citada distribución, comparando con los valores teóricos de la distribución muestral de la media y el rango. Los resultados sugieren que los estudiantes tienen una percepción aceptable del valor esperado, pero que la percepción de la variabilidad es incorrecta y no mejora con la edad. Se observan también el sesgo de equiprobabilidad y la heurística de la representatividad en una parte de los estudiantes, mejorando los resultados según avanza el curso.
La probabilidad conjunta en un proceso de autovalidación
Authors: Parada Fernando León
Published: September 2020

Este artículo contiene una parte de un informe de investigación sobre los procesos de autovalidación que desarrollaron estudiantes de ingeniería a través de un ambiente virtual de aprendizaje. Trata el análisis de los argumentos que encontraron los estudiantes de ingeniería en esquemas tipo mapa conceptual para tres situaciones problemáticas que, en pruebas de tres instancias distintas, les plantearon preguntas cerradas sobre probabilidad con opciones de respuesta que pretendían incurrirles en sesgos de razonamiento. Las tres situaciones de las instancias pretendían incurrir a los estudiantes en la falacia de la conjunción, alterando la regla de extensión y su independencia del contexto, y la segunda ley de De Morgan, debido a opciones ambiguas en el contexto. Las pruebas consistían en hacer que con los aprendizajes previos sobre el tema y la estrategia del mapa desarrollaran sus procesos de autovalidación de las respuestas que hubieran seleccionado al comienzo. Los resultados de las instancias coincidieron en que quienes desistían de sus respuestas inapropiadas fueron mayoría respecto de quienes insistían en las respuestas correctas. Este fenómeno didáctico hace parte de una disertación doctoral en el Doctorado Interinstitucional en Educación de la Universidad Distrital Francisco José de Caldas de Bogotá, Colombia.
Interfaces entre a literacia estatística e as competências crítica e comportamental
Authors: Ribeiro Campos Celso , Pavan Perin Andréa
Published: September 2020

O campo de estudos e pesquisas da Educação Estatística tem se formado com base em um olhar voltado para o desenvolvimento de três competências, a literacia, o raciocínio e o pensamento estatístico. Entre elas, entendemos que a literacia tem uma abrangência mais ampla, de forma que engloba as demais competências, e no contexto brasileiro ela tem ganhado maior ênfase nas pesquisas. Observou-se que diversos pressupostos da Educação Crítica emergem do trabalho com a literacia estatística, por isso já foi mostrado que a competência crítica é outra competência importante para o universo da Educação Estatística. Contudo, em alguns estudos relacionados à competência crítica temos observado detalhes que revelam características próprias do comportamento do indivíduo, evidenciando a necessidade de desenvolvimento de uma competência comportamental. Nessa linha, este artigo tem como objetivo discutir uma articulação entre a competência crítica (como definida nos estudos sobre a Educação Estatística Crítica, que por sua vez é derivada da Educação Matemática Crítica) e a comportamental no contexto da literacia estatística. Trata-se de um estudo de natureza qualitativa e para análise utilizamos a metodologia de Análise Textual Discursiva e os dados coletados são recortes de um trabalho de doutorado. Os resultados indicam que existe uma relação entre essas competências, mas também existem características específicas da competência comportamental para as quais os educadores devem estar atentos.

Authors: Oliveira Camila de Mello Cardoso de , Wolff Mariana Gonçalves de Carvalho
Published: September 2020

Goal: This article aims to present a mathematical modelling study to quantify greenhouse gas emissions in the scope of urban mobility and propose actions for more sustainable cities.

Methodology: This presents an application focused on trips made by cars and motorcycles in some neighborhoods of the City of Rio de Janeiro during 2016 in order to quantify from mathematical equations the greenhouse gas emissions and their proportion to the total greenhouse gases emission of transport in the city, while presenting the capacity of the current bicycle infrastructure to absorb the same displacements with zero carbon trips.

Results: The study reached the result of 127 thousand tons of greenhouse gases emitted by cars and motorcycles, representing 1,64% of the total transport emissions and 2,73% of road transport in this city in 2016.

Limitations of the investigation: The research is limited to the neighborhoods under analysis and the daily travel rate per inhabitant by type of transport.

Practical implications: The study provides environmental impact assessment material able to support proposals for practical applications aimed at mitigating greenhouse gas emissions.

Originality/Value: Measurement of environmental impacts and applications in the transport of the city of Rio de Janeiro, which can be used for comparisons with other neighborhoods in the city and/or other cities.
TINJAUAN PELAKSANAAN ROYA PARTIAL TERHADAP OBJEK HAK TANGGUNGAN
Authors: Anggraeni Lisa , Yunanto Yunanto , Maharani Sukma Novira
Published: September 2020

The mortgage right giver who has paid off his obligations to the mortgage right holder, then cancels the mortgage rights on the object of the mortgage right that is charged. Article 22 paragraph (1) of the Underwriting Right Act "after the mortgage has been written off, the land office has crossed out notes on land rights and certificates". While one of the characteristics inherent in mortgage rights is that the mortgage rights charged cannot be shared, but this provision can be distorted in Article 2 paragraph (2) of the Mortgage Rights Act and implementing regulations issued, namely Regulation of the Minister of Agrarian Number 3 of 1997 which raises the existence of partial roya, which can be done with partial abolition, but the two regulations have differences between one regulation and the other this will certainly lead to legal disputes if there is no general perception about the implementation of partial roya which can ultimately harm the debtor. The purpose of this study is to describe and analyze the partial roya implementation based on the Mortgage Rights Act, Law Number 4 of 1996 and Minister of Agrarian Regulation Number 3 of 1997. Keywords : mortgage rights; partial roya Abstrak Pemberi hak tanggungan yang telah melunasi kewajibannya kepada pemegang hak tanggungan, maka hapuslah hak tanggungan atas obyek hak tanggungan yang dibebankan. Dalam  Pasal 22 ayat (1) UUHT menyebutkan " setelah hak tanggungan hapus, kantor pertanahan mencoret catatan hak atas tanah dan sertipikatnya”. Sementara salah satu sifat yang melekat dalam hak tanggungan yaitu hak tanggungan yang dibebankan tidak dapat dibagi-bagi, tapi ketentuan tersebut dapat disimpangi dalam Pasal Pasal 2 ayat (2) UUHT serta dikeluarkan peraturan pelaksananya yakni Peraturan Menteri Negara Agraria Nomor 3 Tahun 1997 yang memunculkan adanya roya partial yaitu dapat dilakukannya pencoretan oleh sebagian hutang tetapi kedua peraturan tersebut terdapat ketidaksesuaian antara peraturan yang satu dan yang lainnya hal ini tentu menimbulkan adanya sengketa hukum apabila tidak adanya persamaan persepsi mengenai pelaksanaan roya parsial yang pada akhirnya dapat merugikan pihak debitur. Adapun tujuan dilakukannya penelitian ini adalah untuk mendeskripsikan dan menganalisis pelaksanaan roya partial berdasarkan UUHT Nomor 4 Tahun 1996 dan Peraturan Menteri Negara Agraria  Nomor 3 Tahun 1997. Kata kunci : hak tanggungan; roya partial
Multicellular and unicellular responses of microbial biofilms to stress
Authors: Rode Daniel K.H. , Singh Praveen K. , Drescher Knut
Published: September 2020

Biofilms are a ubiquitous mode of microbial life and display an increased tolerance to different stresses. Inside biofilms, cells may experience both externally applied stresses and internal stresses that emerge as a result of growth in spatially structured communities. In this review, we discuss the spatial scales of different stresses in the context of biofilms, and if cells in biofilms respond to these stresses as a collection of individual cells, or if there are multicellular properties associated with the response. Understanding the organizational level of stress responses in microbial communities can help to clarify multicellular functions of biofilms.
Cyclic di-GMP signaling controlling the free-living lifestyle of alpha-proteobacterial rhizobia
Authors: Krol Elizaveta , Schäper Simon , Becker Anke
Published: September 2020

Cyclic-di-GMP (c-di-GMP) is a ubiquitous bacterial second messenger which has been associated with a motile to sessile lifestyle switch in many bacteria. Here, we review recent insights into c-di-GMP regulated processes related to environmental adaptations in alphaproteobacterial rhizobia, which are diazotrophic bacteria capable of fixing nitrogen in symbiosis with their leguminous host plants. The review centers onSinorhizobium meliloti, which in the recent years was intensively studied for its c-di-GMP regulatory network.
Recovering a time-dependent potential function in a multi-term time fractional diffusion equation by using a nonlinear condition

Published: September 2020

In the present paper, we devote our effort to a nonlinear inverse problem for recovering a time-dependent potential term in a multi-term time fractional diffusion equation from an additional measurement in the form of an integral over the space domain.
First we study the existence, uniqueness, regularity and stability of the solution for the direct problem by using the fixed point theorem.
And we obtain the uniqueness of the inverse time-dependent potential term problem.
Numerically, we use the Levenberg–Marquardt method to find the approximate potential function.
Four different examples are presented to show the feasibility and efficiency of the proposed method.
WeChat Group of Chest Pain Center for Patients with Acute ST-segment Elevation Myocardial Infarction: Faster Treatment Speed and Better Prognosis
Authors: Yue Liu , Zhu-Yun Qin , Xin Yang , Rong Tang , Ling-Yun Gao
Published: September 2020

Objective: To explore the effect of establishing a WeChat platform for a chest pain center as a medium to increase the treatment speed and improve the prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI).

Methods: The chest pain center, established by the creation of a WeChat group, included primary hospitals in Chongqing that are not able to perform PPCI and the First Affiliated Hospital of Chongqing Medical University, which is the core of the center and which includes medical staff of the catheter laboratory, the cardiology department, the emergency, the vascular surgery department, and the cardiothoracic surgery department. Patients with acute STEMI who underwent PPCI from January 2017 to November 2018 in the First Affiliated Hospital of Chongqing Medical University were enrolled. The patients (including emergency department visitors, 120 callers, and patients transferred from the critical care unit or other departments) were divided into a WeChat pre-admission startup group (n=311) and a non-WeChat pre-admission startup group (control group, n=172). Patients’ door-to-balloon time, standard door-to-balloon time achievement rate, artery puncture to balloon dilation time, heart failure rate, length of stay, and incidence of adverse events (including fatal arrhythmia, cardiogenic shock, and death) during hospitalization were compared between the two groups.

Results: Four hundred eight-three consecutive patients were enrolled. There was no significant difference in patients’ sex, age, length of stay, and cardiovascular events during hospitalization between the two groups (P>0.05). The door-to-balloon time of the patients in the WeChat pre-admission startup group was much shorter than that of patients in the non-WeChat pre-admission startup group (27.35±10.58 min vs. 88.15±53.79 min, P<0.05). The standard door-to-balloon time achievement rate was significantly higher in the WeChat pre-admission startup group than in the non-WeChat pre-admission startup group (100% vs. 72.09%, P<0.05).

Conclusion: The application of a WeChat platform significantly shortened the door-to-balloon time of patients receiving PPCI and increased the standard door-to-balloon time achievement rate for patients with STEMI. In addition, the platform is also conducive to integrating medical resources and sharing medical information. The establishment of the platform increased the treatment speed and improved the prognosis of patients with STEMI.

This introduction examines the growing interest in science diplomacy and the parallel lack of in-depth historical studies on this new concept. In particular, we first show how the recent attention toward science diplomacy has led to a proliferation of hagiographic accounts reflecting the urgency to support its growth rather than truly investigate its ancestry. We then turn to consider how our historical understanding of science diplomacy could be improved, and how this knowledge could equally be of significance to science diplomacy practitioners today.

This essay is part of a special issue entitled Science Diplomacy, edited by Giulia Rispoli and Simone Turchetti.
The Philosopher and the Rooster
Authors: Somsen Geert
Published: September 2020

Unlike what is often presumed, scientific internationalism persisted through the First World War and its aftermath. Although many scientists aligned themselves with their belligerent nations after 1914, and although Germany and Austria were excluded from international meetings after 1919, the rhetoric celebrating the universally fraternizing nature of science continued as if no such ruptures existed. In this article I argue that this persistence was rooted in the war itself, and particularly in the massive mobilization of academics in wartime propaganda and diplomacy. In these activities they used internationalist arguments and their own supranational status as scientists to defend their countries’ war causes and defame those of the enemy. I illustrate this by following the diplomatic work of the French philosopher Henri Bergson. From the start of the war Bergson presented himself as a neutral scientific arbiter, developing a philosophy of the war (based on his work on life and evolution) as a battle of German barbarity versus universal (not just French) civilization. His government took note and sent Bergson on several diplomatic tasks, most notably a secret mission to the United States, early 1917, where he was to speak to President Wilson to persuade him to enter the war on the French side. Bergson’s universalism and his stature as a philosopher should appeal to Wilson’s dislike of partisanship and craving for the moral high ground. After the war, Bergson-style universalism continued and was institutionalized in the League of Nations and its International Committee on Intellectual Cooperation—with Bergson as its president.

Early Twentieth-Century Ocean Science Diplomacy
Authors: Robinson Sam
Published: September 2020

This paper is a response to a 2018 call for greater understanding of how previous examples of marine science diplomacy could help shape present day efforts to draft a new law of the sea that protects marine biodiversity and conserves the marine environment. It tackles this through analysis of the various twists, turns, and challenges of early science diplomacy efforts in marine science during the early twentieth century. It looks in turn at questions of defining and agreeing on research objectives, how backchannel science diplomacy can become official government diplomacy, and finally, how careful science diplomacy brought Germany back to the international research arena so as to successfully put in place marine conservation measures during the 1920s. In doing this, it argues that the foundation of the International Council for the Exploration of the Seas in 1902 represented a revolutionary moment where supra-national scientific research, coordination, and conservation politics for the ocean first emerged; with International Council for the Exploration of the Sea becoming a key model for all subsequent marine science diplomacy.

The (Science Diplomacy) Origins of the Cold War
Authors: Turchetti Simone
Published: September 2020

The US monopoly of information regarding nuclear weapons was one of the distinctive features of the early Cold War. It encouraged US officials to bolster their country’s hegemonic role in post-war affairs, something that scholars have previously referred to in terms of “atomic diplomacy.” This paper shows that Cold War atomic diplomacy originated in an ancestral form of what we call today “science diplomacy,” distinctive of wartime allied relations during WW2. It first explores how science became a distinctive feature of wartime diplomacy by looking at agreements regarding exchanges of information and collaboration that shaped the relations between wartime allies (US, UK, and the Soviet Union). It then shows that their signing (and, at times, their rejection) eventually paved the way to conflicting views within allied administrations on what to share, making their officials less inclined to pool more knowledge toward the end of WW2. In conclusion, US monopolistic stances and atomic diplomacy originated in these disagreements, also marking the demise of wartime science diplomacy.

Birds Without Borders
Authors: Camprubí Lino
Published: September 2020

The Spanish Doñana Biological Station, inaugurated in 1964, poses two historiographical puzzles. First, it was the first large project of the World Wildlife Fund, which is usually seen as a response to the very specific post-imperial challenges of African parks. Second, it was the first non-alpine park in Spain, and although it was designed and inaugurated in the midst of Francisco Franco’s nationalist dictatorship, it was an explicitly transnational project. This paper approaches Doñana’s unique story through the concept of ecological diplomacy. It points to the diplomatic strategies mobilized by a small group of ecologists with managerial and financial skills. Promoting Doñana, British ornithologists presented it as an African wilderness, which created tensions with Spanish ecologists, themselves colonial scientists. Ecological diplomacy, moreover, refers to a characteristic period between conservation diplomacy and environmental diplomacy. In it, conservation was understood as the top-down management of foreign territories for research purposes. While this can be partly understood as the globalization of the Swiss model for conservation, it arrived in Spain through the mediation of the French Tour du Valat station and of English ecology. Finally, stressing the ecological dimension of this type of conservation diplomacy helps in studying the role of the science of ecology and its transformations. As Doñana became a national park, the WWF’s early emphasis on research was replaced by a new attention to recreation. Max Nicholson’s participation in the International Biology Program granted him an opportunity to favor this model when Doñana became a national park.

Science and Diplomacy around the Earth
Authors: Rispoli Giulia , Olšáková Doubravka
Published: September 2020

In this article we discuss two phases in the evolution of global environmental programs, namely the Man and Biosphere Programme and the International Geosphere-Biosphere Programme, with the aim of showing their hidden diplomatic ambitions from both US and Soviet perspectives. In the 1960s and 1970s, Soviet views on the biosphere prevailed thanks to the influence of Soviet scientists in the International Council of Scientific Unions and the United Nations Educational, Scientific and Cultural Organization. In the 1980s, the domination of this field by US scientists ushered in the establishment of Earth system science as a new research trend based on Earth observation technologies. We argue that despite the influence of Soviet ecologists in directing international coordination of research on the biosphere, Earth system science did not set in a trajectory of environmental cooperation. This outcome can be explained if we take the environmental and ecological turn that arose during the Cold War as being intertwined with political concerns and national interests in both the US and the USSR. Security, scientific diplomacy, and geopolitical issues limited East-West collaboration on the interdisciplinary study of the earth, which instead turned into a sort of cooperative antagonism. The transition from biosphere studies to Earth system science reveals a changing strategy toward environmental problems, which in turn reflects changes in Cold War policy.

Simulation of Flow over a Rotationally Oscillating Square Cylinder at Low Reynolds Numbers
Authors: Singh N.K.
Published: September 2020

Simulation of uniform flow past a square cylinder undergoing rotational oscillations at various frequencies is performed using the ANSYS Fluent CFD package. The frequency ratios FR chosen for the study are 0.4, 0.8 and 1.0. At each frequency ratio, a number of angular amplitudes are selected, and the simulations are performed using a dynamically deforming mesh. The results are obtained from the simulations in terms of the non-dimensional drag and lift forces, vorticity contours, power spectral density plots of lift coefficients and Strouhal number. A general increase in lift and drag coefficients with increasing frequency ratios as well as with increasing amplitudes at a particular frequency ratio, except a few anomalies, is seen. The flow features in the wake and the vicinity of the cylinder are compared for the various parameters. The use of convective boundary condition for the problem is demonstrated.
Mathematical Model of Suspension Seat-Person Exposed to Vertical Vibration for Off-Road Vehicles

Published: September 2020

Off-road drivers are exposed to a high magnitude of vibration at low frequency (0.5-25Hz), that can cause harm and possibly attribute to musculoskeletal disorder, particularly low-back pain. The suspension seat is commonly used on an off-road condition to isolate the vibration transmitted to the human body. Nevertheless, the suspension seat modelling that incorporates the human body is still scarce. The objective of this study is to develop a mathematical modelling to represent the suspension seat-person for off-road vehicles. This paper presents a three degrees-of-freedom lumped parameter model. A curve-fitting method is used for parameter identification, which includes the constraint variable function (fmincon()) from the optimisation toolbox of MATLAB(R2017a). The model parameters are optimised using experimentally measured of suspension seat transmissibility. It was found that the model provides a reasonable fit to the measured suspension seat transmissibility at the first peak of resonance frequency, around 2-3 Hz. The results of the study suggested that the human body forms a coupled system with the suspension seat and thus affects the overall performance of the suspension system.  As a conclusion, the influence of the human body should not be ignored in the modelling, and a three-degrees degree-of-freedom lumped parameter model provides a better prediction of suspension seat transmissibility. This proposed model is recommended to predict vibration transmissibility for off-road suspension seat.

The main disadvantage of the vertical-axis turbine is its low coefficient of performance. The purpose of this work was to propose a method to improve this performance by investigating the hydrodynamic forces and the flow-field of a foil that was modified with a sinusoidal leading-edge tubercle. NACA 63(4)021 was chosen as the original foil since it has a symmetrical profile that is suitable for use on a vertical-axis tidal-current turbine. The study was conducted using a numerical simulation method with ANSYS-CFX Computational Fluid Dynamics (CFD) code to solve the incompressible Reynolds-Averaged Navier-Stokes (RANS) equations. Firstly, the simulation results of the original foil were validated with available experimental data. Secondly, the modified foils, with three configurations of tubercles, were modelled. From the simulation results, the tubercle foils, when compared with the original foil, had similar lift performances at low Angles of Attack (0-8 degrees of AoA), lower lift performances at medium AoA (8-19 degrees) and higher lift performances at high AoA (19-32 degrees). A tubercle foil with Height/Chord (H/C) of 0.05 can maintain the static stall condition until 32 degrees. Therefore, a vertical-axis turbine with tubercle-blades provides an opportunity to increase its performance by extending the operational range for extracting energy in the dynamic stall condition.
