Punctuation patterns in a 17th-century medical manuscript: A corpus-based study of G.U.L. MS 303, Treatise on the Diseases of Women
Authors: Bernal Soluna Salles
Published: May 2019

The regularization of punctuation and spelling is one of the distinctive features of Early Modern English (Lass 1999: 8), although in the case of handwritten material punctuation depended greatly on the scribe’s preference, and it was considered to be rather unpredictable. However, recent studies have demonstrated that punctuation followed particular patterns depending on the typology of the text (Calle-Martín 2004, Calle-Martín & Miranda-García 2005). In this line, this paper investigates the punctuation system in a 17th century medical manuscript, entitled Treatise on the Diseases of Women (Glasgow University Library, MS Hunter 303), following the theoretical framework proposed by Lucas (1971).
Exploring EFL teachers’ use of written instructions and their subsequent verbal instructions for the same tasks
Authors: Ha Chau Bao , Wanphet Phalangchok
Published: May 2019

Instructions are what English as a Foreign Language (EFL) teachers use in order to draw students’ attention to a task, engage them in the task, run classroom activities, and prompt them to provide a product for the purposes of assessment. The focus of this descriptive, naturalistic, and observational study is to explore how the teachers use written instructions and their subsequent spoken instructions given by the same EFL teachers for the same tasks. The data were gathered from two classroom teaching episodes of two EFL teachers to see how verbal instructions compliment written instructions. An analysis of the features of the EFL teachers’ written instructions and their subsequent spoken instructions reveals that there are many different spoken instruction features used to enhance written instructions. These features result ultimately in the students understanding the task requirements. The findings can be useful for lesson preparation and for raising teachers’ awareness that spoken instructions provide features which enhance students’ understanding of the written instructions for a task.
‘I have every reason to love England’: Black neo- Victorianism and transatlantic radicalism in Belinda Starling’s The Journal of Dora Damage (2007)
Authors: Martín-González Juan-José
Published: May 2019

This paper provides a close reading on post-colonial engagements with American slavery in Belinda Starling’s neo-Victorian novel The Journal of Dora Damage (2007), particularly on the transoceanic links between Antebellum America and Victorian Britain. Firstly, this article engages with previous feminist criticism on the novel in order to analyse Starling’s stimulating revision of Victorian female abolitionism and interracial relations. Secondly, drawing on recent historical reconstructions on the presence of American slaves in Victorian England and seeking to open new avenues of research within this novel, this paper considers the transatlantic context inherent in Starling’s narration, particularly the interplay between nineteenth-century radical discourses and African-American discourses of liberation.

Introduction
Authors: Walker Terry , Kytö Merja
Published: May 2019

This Special Issue of the Nordic Journal of English Studies is devoted to historical linguistics, and focuses on ‘speech’ from past periods. As the title suggests, we are interested in not only the language of speech-based or, in a wider sense, speech-related texts but also the (re)presentation of speech in other types of historical texts.
Periphrastic do in English Witness Depositions 1560– 1760
Authors: Söderlund Anders
Published: May 2019

This paper exploits the genre of witness depositions for an examination of the development of periphrastic do in the Early Modern English period. Depositions are speech-related texts, reports of authentic speech events related to a court case. Periphrastic do (in contrast to simple V, i.e., without an auxiliary) is investigated in terms of the parameters of time, and sentence type (affirmative, negative, interrogative, and imperative) against the background of previous research. Further potential linguistic and extra-linguistics factors influencing usage that are taken into account include type of verb, and region. The development in the use of the do-construction across time, and as regards the parameter of region, was found to be generally in line with previous research; however, monosyllabic verbs were found to encourage do-periphrasis, which is in contrast to previous findings.
‘The Man Who Would Be King’ (1888): Rudyard Kipling’s Last Imperial Story
Authors: Ambrosini Richard
Published: May 2019

With its complex, metafictional narrative-frame structure and ironic, detached treatment of imperial history and mythology, Rudyard Kipling’s 14,000-word short story ‘The Man Who Would Be King’ (1888), is a privileged site in the study of the ‘imperial short story’—a cultural phenomenon which, when viewed in its historical and geopolitical context, can be defined as ‘imperial short story’ and, in the history of colonial and colonialist fiction, as a specific literary subgenre: the ‘imperial short story’. Returning to ‘The Man’ through the literary-historical perspective opened up by the subgenre of the imperial short story casts new light on the mechanisms that regulate the text’s several transitions: from the section narrated by a journalist-narrator (who shares many traits with the author himself), to the tragicomic adventure story which the ‘man who would be king’ has previously related to the journalist. This new light offers a way to understand both how Kipling’s text represents and comments upon a shift in geographical perspective on British India and the implications of the latter for his art.
“This is an age for news”: A corpus-based analysis of the word NEW(E)S in the spoken discourse of Early Modern English society (1560-1760)
Authors: Cecconi Elisabetta
Published: May 2019

In my paper, I shall be examining how the voracity for news which characterises Tudor and―to a larger extent―Stuart England can be mapped on the spoken discourse of society in Early Modern England. To do so I shall analyse the Corpus of English Dialogues 1560-1760 as representative of the spoken interaction of the past in the categories of authentic and constructed dialogues. By applying tools of corpus-assisted discourse analysis (Partington 2004, 2009), I shall provide a quantitative and qualitative investigation of the word NEWS in the attempt to grasp the impact of news on people’s everyday life. While quantitative evidence will help us establish possible patterns of news vocabulary distribution from 1560 to 1760, the qualitative analysis of keywords in context will allow us to uncover collocational sets which can be interpreted in light of the evolving relationship between society and news in the historical period examined. The paper will also aim to provide an example of how corpus-assisted research in historical sociolinguistics can help us trace relations between language practices and context.
Editor’s Preface
Authors: Lipski Jakub
Published: May 2019

the Image’ gradually realising Marshall McLuhan’s prophecy of ‘postliterate societies’, we find ourselves in the position to re-assess the co-existence of words and images in literary discourse and the ways in which the paradigm of ‘vision’ informs our understanding of texts. This is the implied agenda behind the present collection of articles that address the complexity of what might be termed ‘visual poetics’. This being our incentive, the essays making up this special issue discuss a variety of literary works, from Shakespeare to the present day, and persuasively demonstrate the irresolvable connection between seeing and reading.
Early Modern visual-verbal esoteric imagery and the theatre: Julius Caesar 1.3
Authors: Myklebost Svenn-Arve
Published: May 2019

Adopting a method which combines close readings of iconography and playtext with broader historicist and cultural investigations, this article attempts to contribute to the field of visual-verbal Shakespeare studies through outlining how polysemous images and imagery are recombined within circular designs (wheels, spheres, globes, playhouses) upon which ‘actors’ are ‘staged’, in order to facilitate spiritual and practical insight into the micro- and the macrocosm. All these elements—or equivalents thereof—are present in the Renaissance theatre also, and Act 1 Scene 3 of William Shakespeare’s Julius Caesar contains a striking range of esoteric verbal-visual imagery offering an opportunity to analyse its compositional design and to assess its effects. This article argues that the esoteric visual tradition plays a major role in the composition and generation of meaning within that play, and that studying these aspects of Julius Caesar and the stage upon which it was performed aids us in seeing how it approached societal and political issues in Elizabethan England.
Urban(e) visualization and Early Modern drama: Ben Jonson’s ‘Spectral Cities’
Authors: Johnson Anthony W.
Published: May 2019

This paper explores urbanization, and the impact of new technologies on early modern dramatic visualization. It demonstrates how the frontispiece to Ben Jonson’s 1616 Folio summons up spectres of antiquity, high renaissance culture, and the renovatio urbis: reconfiguring them as models for new negotiations of the urban and urbane. It reveals how the Folio’s opening play, Every Man in his Humour, powerfully maps Florentine urban geography and practice onto its revised London setting. And, equally, how its closing masque, The Golden Age Restor’d, formally complements the programme of Jonson’s collaborator, Inigo Jones, for the new Whitehall Banqueting House (1622).
The perils of aesthetic pleasure in Ann Radcliffe’s The Romance of the Forest and The Mysteries of Udolpho
Authors: Lipski Jakub
Published: May 2019

In her works, Ann Radcliffe continually expressed an unwavering appreciation of aesthetic pleasure. Accordingly, one significant level of character evaluation in her fictional worlds is the characters’ sensitivity to aesthetic experience, which typically functions as an indicator of virtue. In line with the recent revisionist tendencies in Radcliffe criticism, problematising things that so far have been taken for granted, this article is concerned with a negative, or at least dialectical, evaluation of aesthetic pleasure, which is offered in The Romance of the Forest (1791) and The Mysteries of Udolpho (1794). In particular, by concentrating on a reconciliation of villainy and aestheticism that is indicated in the narratives, the article shows how the seemingly antithetical arrangement of characters becomes destabilised; whereas by problematising the female sensitivity to art, it argues that aesthetic experience may pose a threat to the stability of selfhood. The heroines’ reactions are read as illustrative of an implied dialectic between vulnerability and empowerment, which arguably underpins Radcliffe’s handling of aesthetic pleasure in general.

Exploring if/whether variation in subordinate interrogatives1
Authors: Lastres-López Cristina
Published: May 2019

This paper investigates the variation between if and whether (e.g. I don’t know if/whether you are right), on the grounds that prior studies on complementation in English have not sufficiently addressed the variation between these two complementizers. Based on data extracted from the British component of the International Corpus of English, the results from the study show that although if and whether are mostly interchangeable complementizers, there are grammatical, semantic and stylistic constraints governing the choice of conjunction. The results suggest that a number of factors can influence the choice of complementizer, such as the matrix verb or the presence of an explicit alternative in clauses introduced by the conjunction or. In addition, extralinguistic factors such as age and sex are also revealed as playing a role in the choice of complementizer.
At the interface between Contrastive Analysis and Learner Corpus Research: A parallel contrastive approach1
Authors: Hasselgård Hilde , Oksefjell Ebeling Signe
Published: May 2019

This paper presents a model for combining contrastive analysis and interlanguage analysis. It can be seen as an extension of Granger’s (1996) Integrated Contrastive Model, but it explicitly requires a bidirectional parallel corpus for the contrastive analysis and matching learner corpora for the (multiple) interlaguage analysis. Thus, the model operates at the interface between Contrastive Analysis and Learner Corpus Research. Within the model, the contrastive, cross-linguistic analysis produces hypotheses for learner behaviour in the languages examined. Hence the learner corpus study of L2 data includes a cross-linguistic interlanguage analysis, based on comparable data produced by (at least) two learner groups (with different L1s and different L2s). As an illustration of the model, the English noun people and its typical Norwegian translation correspondences (FOLK and MENNESKE) are studied, with particular attention to postmodification patterns. The proposed Parallel Contrastive Model is shown to have the potential to throw new light on the cross-linguistic relationship between languages and interlanguages in a common framework.
Live, Moribund, and Dead Metaphors
Authors: Alm-Arvius Christina
Published: May 2019

The term ‘dead metaphor’ is an established one, and it denotes vocabulary items that have lost their metaphorical character. The question is however what this means more exactly. In other words: how can members of this category be identified, and distinguished especially from uses that potentially retain their metaphorical quality, even if it is ordinarily not so obvious? The latter can be termed ‘dying’ or ‘moribund metaphors’, and the main aim of this article is to establish how they are different from dead metaphors. Moreover, both dead metaphors and moribund ones are different from ‘live metaphors’, and a further, more general aim is to analyse and describe what definitional characteristics prototypical examples of each of these three categories exhibit, and how they are different from each other.

Freudian Economies and Constructions of Love in Poe's Tales
Authors: Sørensen Bent
Published: May 2019

A clean, Freudian-inspired reading of Poe's texts is hard to come by. A major reason for writing this paper is the very basic claim that Poe's literary constructs are perfectly intelligible to the modern reader without needing what most critics regardless of theoretical persuasion have offered for decades: a psycho-biographical apparatus as introduction. In fact, this paper argues that donning allegorical glasses in order to find correspondences between Poe's life and Poe's work is at best a futile exercise and at worst a blinding of the reader/analyst to the signification of Poe's tales. Paradoxically, the exercise is not futile because correspondences cannot be found, but on the contrary because so many and so comprehensive correspondences can be construed that one should immediately suspect that this is not entirely without auctorial design in itself.

Acontecimientos del Plan Ceibal. Una compleja trama de mediaciones soportando la apuesta inclusiva
Authors: Kachinovsky Melgar Alicia María , Paredes-Labra Joaquín , Dibarboure Reynes Michel
Published: May 2019

En el marco de un proyecto sobre el impacto del Plan CEIBAL en los procesos de inclusión social de familias beneficiadas por el modelo 1 a 1 de integración de tecnología, se procura ilustrar la multicausalidad del fenómeno estudiado. Para ello se detallan algunas vicisitudes de la relación con el saber de una escolar con la que se trabajó. En ella se pone de manifiesto la pluralidad de determinantes de las modificaciones operadas en su subjetividad y posicionamiento frente a lo escolar. La potencia de la dimensión subjetiva para producir cambios educativos se articula con el deseo de saber y éste con el deseo de saber del otro significativo.Se trata de un estudio de casos de tipo instrumental, de una investigación cualitativa afiliada al enfoque clínico de investigación en ciencias humanas, que privilegia como instrumentos de indagación los dispositivos conversacionales. El análisis del material discursivo recogido pone de relieve el impacto del Plan CEIBAL en la vida escolar del caso en cuestión y el conjunto de condicionantes personales e institucionales que lo han hecho posible. Entre los hallazgos se destaca la detección de una cadena de mediadores humanos, solidarios entre sí, que hacen posible la accesibilidad a la tecnología.
Inclusão digital em uma escola do campo: movimentos provocados a partir da implantação de uma política pública no modelo 1:1
Authors: Pescador Cristina Maria , Valentini Carla Beatris
Published: May 2019

Este trabalho apresenta os movimentos provocados em uma comunidade escolar após a implantação de uma política pública educacional: Programa Nacional de Educação no Campo (Pronacampo). O estudo qualitativo de cunho exploratório acompanha o processo desde a distribuição de laptops no modelo 1:1 em uma escola do campo, em regime de classe multisseriada - da Educação Infantil ao 5º ano, localizada no interior do Rio Grande do Sul (Brasil). A Cartografia, segundo Kastrup (2008), serve de inspiração para o método de investigação cujo objetivo é identificar e analisar as mudanças provocadas nas práticas dentro e fora da sala de aula nessa comunidade escolar a partir da inserção dos laptops. Os dados permitem perceber alguns movimentos significativos de mudança nas ações dos professores, estudantes e seus familiares.  A análise desses dados é feita à luz de alguns conceitos construtivistas e de letramento digital. Percebeu-se que o longo período sem conectividade na escola não impediu que a comunidade escolar, em um esforço mútuo, com engajamento das famílias, encontrasse soluções criativas para explorar os recursos disponíveis como uma oportunidade de construção de conhecimento do mundo dentro e fora da escola.
Mediações de leitura visual na educação básica: em foco as narrativas das crianças
Authors: Francez Letícia , Neitzel Adair De Aguiar
Published: May 2019

Este artigo tem por objetivo discutir sobre a mediação de leitura de imagem no ensino da arte que considera as narrativas das crianças como elemento mediador. Por meio da metodologia da Pesquisa Educacional Baseada em Arte (PEBA) e do método da a/r/tografia, foram realizadas mediações de leitura de obras de arte com alunos de uma turma de 1º ano do Ensino Fundamental, crianças com seis anos de idade, de uma escola municipal de Balneário Camboriú, Santa Catarina, Brasil. O instrumento de produção de dados foi o diário de campo do pesquisador. O aporte teórico principal foi Martins, Picosque, e Guerra (2009), Pillar (2014) e Rossi (2009) sobre leitura de imagem e Neitzel, Ferri, e Borba (2018), Martins (2014) e Uriarte, Neitzel, Carvalho, e Kupiec (2016) sobre mediação. Como resultado, sinalizamos que quando as aulas de arte na educação formal também têm como responsabilidade a educação estética das crianças, o uso das narrativas é uma das possibilidades para estabelecer-se uma mediação. Quando a narrativa do professor é suspensa para dar lugar à narrativa das crianças, quando a apreciação da obra possui espaço e é percebida como conteúdo curricular, amplia-se a possibilidade de fazer-se experiência. Por meio das intervenções foi possível perceber que quando a mediação permite encontros entre obra e fruidor, quando se pode partilhar com o outro as narrativas construídas a partir das obras, a escola torna-se espaço de educação estética e as aulas de leitura visual podem agregar na formação cultural das crianças.
CRISPR/Cas9-Mediated Gene Knockout of ARID1A Promotes Primary Progesterone Resistance by Downregulating Progesterone Receptor B in Endometrial Cancer Cells
Authors: Wang Haizhen , Tang Zhenghua , Li Ting , Liu Menglu , Li Yong , Xing Baoling
Published: May 2019

Medroxyprogesterone (MPA) is used for the conservative treatment of endometrial cancer. Unfortunately, progesterone resistance seriously affects its therapeutic effect. The purpose of the current study was to investigate the influence of deletion of AT-rich interactive domain 1A (ARID1A)
in progesterone resistance in Ishikawa cells. Ablation of ARID1A was conducted through the CRISPR/Cas9 technology. Acquired progesterone-resistant Ishikawa (Ishikawa-PR) cells were generated by chronic exposure of Ishikawa cells to MPA. The sensitivity of the parental Ishikawa, Ishikawa-PR,
and ARID1A-deficient cells to MPA and/or LY294002 was determined using the Cell Counting Kit-8 (CCK-8) assay and flow cytometry analysis. In addition, Western blot analysis and reverse transcription-polymerase chain reaction was performed to evaluate the mRNA and protein expression levels
of ARID1A, progesterone receptor B (PRB), and P-AKT. Both Ishikawa-PR and ARID1A knockout cells showed insensitivity to MPA, downregulation of PRB, and hyperphosphorylation of AKT compared to the parental Ishikawa cells. Pretreatment with LY294002 significantly enhanced the ability of MPA
to suppress proliferation and to induce apoptosis in the parental and Ishikawa-PR cells via the inhibition of AKT activation and upregulation of PRB transcriptional activity. However, the PRB transcriptional activity and insensitivity to MPA were irreversible by LY294002 in ARID1A-deficient
cells. Ablation of ARID1A is associated with low PRB expression, which serves an important role in primary progesterone resistance. Akt inhibition cannot rescue PRB or sensitize to MPA in ARID1A knockout cells. These findings suggest that ARID1A may act as a reliable biomarker to predict the
response for the combination of AKT inhibitor and MPA treatment.
Visiting Scuttled Ships: An Examination of the Important Elements of the Wreck Diving Experience
Authors: Seaman Alana N. , Depper Gina L.
Published: May 2019

Scuba diving is an increasingly popular recreational and tourist pastime. Diving enthusiasts are recognized for their dedication to the sport and willingness to both travel to and spend money on new and unique experiences. Subsequently dive tourism has become a multibillion dollar industry.
In turn, many coastal (and other diveable) destinations are investing in the development of local dive sites. However, many popular dive attractions such as naturally occurring coral reefs and historic wrecks are fragile, easily damaged, and/or adversely impacted by visitors. Artificial reefs,
or structures purposely sunk to create habitats for marine life and infrastructure for unique diving experiences (often stripped-down large scale pieces of machinery), can draw tourists away from fragile natural ecosystems. Ideally, artificial reefs could also be utilized as underwater cultural
heritage management tools similarly drawing visitors away from aging, delicate historic wrecks. However, little is known about wreck divers and/or the wreck diving experience. Thus, the purpose of this study was to examine the specific aspects of the popular purposely scuttled wreck, the
USS Spiegel Grove (off the coast of Key Largo) that contributed to visitors' dive experiences. A total of 100 TripAdvisor reviews about the Spiegel Grove were collected and analyzed as data. The majority of reviews were positive and revealed that the size of the ship, the challenge
of the dive, the ability to penetrate the ship, the chance to check the dive off a bucket list, and the opportunity to see marine life contributed to divers' experiences. Historic ties were surprisingly of little importance. Although more research is needed, these findings should help destinations
to better plan for and design artificial reefs aimed at attracting wreck divers.
Correlation of surface-enhanced Raman scattering (SERS) with the surface density of gold nanoparticles: evaluation of the critical number of SERS tags for a detectable signal
Authors: Amendola Vincenzo
Published: May 2019

The use of plasmonic nanotags based on the surface-enhanced Raman scattering (SERS) effect is highly promising for several applications in analytical chemistry, biotechnological assays and nanomedicine. To this end, a crucial parameter is the minimum number of SERS tags that allows for the collection of intense Raman signals under real operating conditions. Here, SERS Au nanotags (AuNTs) based on clustered gold nanoparticles are deposited on a substrate and analyzed in the same region using Raman spectroscopy and transmission electron microscopy. In this way, the Raman spectra and the surface density of the SERS tags are correlated directly, showing that 1 tag/µm2 is enough to generate an intense signal above the noise level at 633 nm with an excitation power of only 0.65 mW and an acquisition time of just 1 s with a 50× objective. The AuNT density can be even lower than 1 tag/µm2 when the acquisition time is extended to 10 s, but must be increased to 3 tags/µm2 when a 20× objective is employed under the same excitation conditions. In addition, in order to observe a linear response, it was found that 10 SERS AuNTs inside the probed area are required. These findings indicate that a better signal-to-noise ratio requires high-magnification optics, while linearity versus tag number can be improved by using low-magnification optics or a high tag density. In general the suitability of plasmonic SERS labels for ultrasensitive analytical and biomedical applications is evident.
Ficus pongumphaii (Moraceae), a new species from Thailand, compared with the ambiguous species F. talbotii
Authors: Chantarasuwan B. , Sungkaew S. , Pruesapan K. , Baas P. , van Welzen P.C.
Published: May 2019

A deciduous shrub previously included in Ficus talbotii for many years, is now regarded as a new species, Ficus pongumphaii. It is morphologically distinct from F. talbotii with as typical characters the densely brown pubescent to tomentose or villous on leafy twig;
the elliptic, suborbicular to obovate leaf blades that are brown tomentellous on the upper surface and brown floccose tomentose to villous underneath; the pedunculate figs are obovate, brown floccose or villous outside and have internal hairs. The leaf anatomy shows a multiple epidermis on
both surfaces; enlarged lithocysts on both sides of the lamina, which are more abundant adaxially and with very few abaxially. The species, endemic to Thailand, is named after the great Thai dendrologist, Associate Professor Somnuek Pongumphai.
The Pulsating Eclipsing Binary TIC 309658221 in a 7.59-day Orbit
Authors: Lee Jae Woo , Kristiansen Martti H. , Hong Kyeongsoo
Published: May 2019

We present a new eclipsing binary (EB) showing multiperiodic oscillations using the first three sectors of Transiting Exoplanet Survey Satellite (TESS) photometry. The eclipse and pulsation light curves of TIC 309658221 were modeled using an iterative method to obtain a consistent photometric solution. The TESS target is a circular-orbit, detached binary system with a mass ratio of 0.349, an inclination angle of 80.°42, and a temperature difference of 847 K between the components. The primary component of the system lies near the red edge of the δ Sct instability region on the main-sequence band in the Hertzsprung–Russell diagram. Multiple frequency analyses were applied to the eclipse-subtracted residuals after removing the binary effects in the observed data. These resulted in the detection of 26 frequencies, of which

were independent pulsation frequencies. The 20 other frequencies could be mainly caused by orbital harmonics (f
8 and f
11) or combination frequencies. The period ratios and pulsation constants of the

frequencies are in the ranges of

and Q =0.027–0.036 days, respectively, which are typical of δ Sct type. The results reveal that TIC 309658221 is an eclipsing δ Sct star with an orbital period of 7.5952 days and pulsation frequencies of 9.94–13.01 day−1. This work demonstrates that the two-minute cadence observations of TESS are very useful for the study of pulsating EBs with multiple frequencies and low amplitudes.
Radioactive Heating and Late Time Kilonova Light Curves
Authors: Kasen Daniel , Barnes Jennifer
Published: May 2019

Compact object mergers can produce a thermal electromagnetic counterpart (a “kilonova”) powered by the decay of freshly synthesized radioactive isotopes. The luminosity of kilonova light curves depends on the efficiency with which beta-decay electrons are thermalized in the ejecta. Here we derive a simple analytic solution for thermalization by calculating how accumulate electrons lose energy adiabatically and via plasma interactions. The thermalization efficiency is well described by

where the timescale

is a function of the ejecta mass and velocity and the exponent

depends on the electron energies and the thermalization cross-sections. For a statistical distribution of r-process isotopes with radioactive power

and n = 1, the late time kilonova luminosity asymptotes to

and depends super-linearly on the ejecta mass,

. If a kilonova is instead powered by a single dominate isotope, we show that the late time luminosity can deviate substantially from the underlying exponential decay and the heating from the accumulation of trapped electrons eventually exceeds the instantaneous radioactivity. Applied to the kilonova associated with the gravitational wave source GW170817, these results imply that a possible steepening of the light curve at ≳7 days is unrelated to thermalization effects and instead could mark the onset of translucency in a high opacity component of ejecta. The analytic results should be convenient for estimating the properties of observed kilonovae and assessing the potential late time detectability of future events.

We have searched for short periodicities in the light curves of stars with T
eff cooler than 4000 K made from 2-minute cadence data obtained in Transiting Exoplanet Survey Satellite sectors 1 and 2. Herein we report the discovery of 10 rapidly rotating M dwarfs with highly structured rotational modulation patterns among 371 M dwarfs found to have rotation periods less than 1 day. Starspot models cannot explain the highly structured periodic variations that typically exhibit between 10 and 40 Fourier harmonics. A similar set of objects was previously reported following K2 observations of the Upper Scorpius association. We examine the possibility that the unusual structured light curves could stem from absorption by charged dust particles that are trapped in or near the stellar magnetosphere. We also briefly explore the possibilities that the sharp structured features in the light curves are produced by extinction by coronal gas, by beaming of the radiation emitted from the stellar surface, or by occultations of spots by a dusty ring that surrounds the star. The last is perhaps the most promising of these scenarios. Most of the structured rotators display flaring activity, and we investigate changes in the modulation pattern following the largest flares. As part of this study, we also report the discovery of 17 rapidly rotating M dwarfs with rotational periods below 4 hr, of which the shortest period is 1.63 hr.

Meteoroids largely disintegrate during their entry into the atmosphere, contributing significantly to the input of cosmic material to Earth. Yet, their atmospheric entry is not well understood. Experimental studies on meteoroid material degradation in high-enthalpy facilities are scarce and when the material is recovered after testing, it rarely provides sufficient quantitative data for the validation of simulation tools. In this work, we investigate the thermo-chemical degradation mechanism of a meteorite in a high-enthalpy ground facility able to reproduce atmospheric entry conditions. A testing methodology involving measurement techniques previously used for the characterization of thermal protection systems for spacecraft is adapted for the investigation of ablation of alkali basalt (employed here as meteorite analog) and ordinary chondrite samples. Both materials are exposed to a cold-wall stagnation point heat flux of 1.2 MW m−2. Numerous local pockets that formed on the surface of the samples by the emergence of gas bubbles reveal the frothing phenomenon characteristic of material degradation. Time-resolved optical emission spectroscopy data of ablated species allow us to identify the main radiating atoms and ions of potassium, calcium, magnesium, and iron. Surface temperature measurements provide maximum values of 2280 K for the basalt and 2360 K for the chondrite samples. We also develop a material response model by solving the heat conduction equation and accounting for evaporation and oxidation reaction processes in a 1D Cartesian domain. The simulation results are in good agreement with the data collected during the experiments, highlighting the importance of iron oxidation to the material degradation.
Excitation of Planetary Obliquities through Planet–Disk Interactions
Authors: Millholland Sarah , Batygin Konstantin
Published: May 2019

The tilt of a planet’s spin axis off its orbital axis (“obliquity”) is a basic physical characteristic that plays a central role in determining the planet’s global circulation and energy redistribution. Moreover, recent studies have also highlighted the importance of obliquities in sculpting not only the physical features of exoplanets but also their orbital architectures. It is therefore of key importance to identify and characterize the dominant processes of excitation of nonzero axial tilts. Here we highlight a simple mechanism that operates early on and is likely fundamental for many extrasolar planets and perhaps even solar system planets. While planets are still forming in the protoplanetary disk, the gravitational potential of the disk induces nodal recession of the orbits. The frequency of this recession decreases as the disk dissipates, and when it crosses the frequency of a planet’s spin axis precession, large planetary obliquities may be excited through capture into a secular spin–orbit resonance. We study the conditions for encountering this resonance and calculate the resulting obliquity excitation over a wide range of parameter space. Planets with semimajor axes in the range 0.3 au ≲ a ≲ 2 au are the most readily affected, but large-a planets can also be impacted. We present a case study of Uranus and Neptune, and show that this mechanism likely cannot help explain their high obliquities. While it could have played a role if finely tuned and envisioned to operate in isolation, large-scale obliquity excitation was likely inhibited by gravitational planet–planet perturbations.
Divergence rates of subviral pathogens of angiosperms abruptly decreased at the Cretaceous-Paleogene boundary
Authors: Bajdek Piotr
Published: May 2019

Biogeographic distribution of infected plants and the continental drift theory allow a tentative time calibration of the phylogenetic tree of Pospiviroidae. Hypothetically, viroids evolved in the late Early Cretaceous shortly after the appearance of angiosperms, which constitute their only known hosts. No decline in the estimated divergence rates of Pospiviroidae is observed during the Late Cretaceous but it appears that they abruptly decreased at the Cretaceous-Paleogene boundary. However, an adaptive radiation of Pospiviroidae which occurred in the late Paleocene may reflect a recovery from the Cretaceous-Paleogene (K–Pg) mass extinction. It seems that the evolutionary history of viroids has been in part shaped by radiation and extinction events of angiosperms. Herein, for the first time I show the probable impact of a mass extinction event on the divergence rates of subviral pathogens, which are the simplest known “lifeforms”.

An ichthyofaunal list of bycatch species was compiled, the fish captured by bottom gill-nets set at approximately 300 m depth in the Uraga Suido Channel central Japan. Fragmentary ichthyofaunal lists are available for this area; these lists have focused on chondrichthyans or commercial actinopterygians, but voucher specimens have not been prepared for museum storage. An initial list of the fish fauna was compiled with vouchers, and seven species not previously recorded from the channel are reported. Most of these species belong to the Class Actinopterygii; Apristurus platyrhynchus (Tanaka, 1909), Beryx decadactylus Cuvier, 1829, Hoplostethus japonicus Hilgendorf, 1879, Sebastes iracundus (Jordan & Starks, 1904), Scalicus amiscus (Jordan & Starks, 1904), Atrobucca nibe (Jordan & Thompson, 1911), and an unidentified species of the eelpout family Zoarcidae. The taxonomic identity of the eelpout and the biogeography of the Uraga Suido Channel are considered. Further research is required to resolve outstanding faunistic issues, but live collections will likely end when the aging fishers who provide the specimens retire. At that point, existing museum collections will become increasingly important for future research. Examination of a collection that may have been previously deposited in the Chiba Prefectural Museum will be essential.
TEACHING HOW TO USE A REPETITIVE SCHEDULING METHOD WHEN PLANNING A GREEN CONDOMINIUM BUILDING
Authors: Taemthong Wannawit , Chaissard Nattasit
Published: May 2019

This paper aims to present a methodology for use in construction planning named the Repetitive Scheduling Method (RSM). Students on a graduate level construction management program can learn how to create a RSM schedule to be applied to a real project. Typically, the Critical Path Method (CPM) is used to plan general construction projects. This paper presents a case study wherein a CPM diagram is transformed into a RSM schedule for use in the construction of a green condominium. RSM is the most suitable tool for planning repetitive projects like condominium buildings, apartment complexes, or real estate development projects. It utilizes an uninterrupted flow of resource concept in order to eliminate manpower-related resource wastage. As a result, construction productivity can be improved by using the right construction planning tool on the right project. Interested graduate students researching construction engineering can apply RSM on their repetitive projects in the future.

The most urgent task in the construction industry today is energy saving at all stages: from the production of building materials, products and structures to the construction of buildings and their operation. Combining these problems forms one of the directions of innovation policy of the majority of subjects of the Russian Federation – strengthening of local capacity and demonstration of solutions to improve energy and resource saving in construction. Building materials industry-one of the leading sectors of the economy, which is quite effectively uses secondary products of many industries for the production of various building materials. Development of production of building materials in this direction is associated with many aspects: the depletion of natural resources, high energy intensity of a number of technological processes of extraction and processing of raw materials; threat to environmental safety of the Russian Federation; lack of waste disposal sites; negative impact on the air, water and plant environment, human and animal health.

During the operation of thermal power plants, boilers, incinerators, vehicles, industrial enterprises for the production of synthetic fatty acids, building materials, paints, textiles, cardboard, paper, as well as resins and products based on them – plywood, chipboards, wood-fiber boards, plastics, etc. The environment is contaminated with formaldehyde. Formaldehyde acts climatically and toxically on local, regional and global processes in the environment and contributes to a high level of air pollution (air pollution index > 14) in almost all industrialized regions of Russia. Products containing formaldehyde, getting into residential and non-residential premises, create an environmental risk to public health. The article is devoted to determining the effect of formaldehyde on woody plants by biochemical and electrophysiological methods and developing a method of reducing the concentration of formaldehyde in the environment by introducing into industrial materials aluminosilicate sorbents of different crystal chemical structure, processed thermo-, in a pulsed magnetic field and under the combined effect of a pulsed magnetic field and temperature effects.

Extrahepatic bile ducts are characterized by the presence of peribiliary glands (PBGs), which represent stem cell niches implicated in biliary regeneration. Orthotopic liver transplantation may be complicated by non-anastomotic strictures (NAS) of the bile ducts, which have been associated with ischemic injury of PBGs and occur more frequently in livers obtained from donors after circulatory death than in those from brain-dead donors. The aims of the present study were to investigate the PBG phenotype in bile ducts after transplantation, the integrity of the peribiliary vascular plexus (PVP) around PBGs, and the expression of vascular endothelial growth factor-A (VEGF-A) by PBGs. Transplanted ducts obtained from patients who underwent liver transplantation were studied (N=62). Controls included explanted bile duct samples not used for transplantation (N=10) with normal histology. Samples were processed for histology, immunohistochemistry and immunofluorescence. Surface epithelium is severely injured in transplanted ducts; PBGs are diffusely damaged, particularly in ducts obtained from circulatory-dead compared to brain-dead donors. PVP is reduced in transplanted compared to controls. PBGs in transplanted ducts contain more numerous progenitor and proliferating cells compared to controls, show higher positivity for VEGF-A compared to controls, and express VEGF receptor-2. In conclusion, PBGs and associated PVP are damaged in transplanted extrahepatic bile ducts; however, an activation of the PBG niche takes place and is characterized by proliferation and VEGF-A expression. This response could have a relevant role in reconstituting biliary epithelium and vascular plexus and could be implicated in the genesis of non-anastomotic strictures.
Enhancement of biogenic emissions of VOCs in the semi-arid region of India during
winter to summer transition period: Role of meteorological conditions
Authors: Tripathi Nidhi , Sahu Lokesh Kumar
Published: May 2019

Abstract. Emissions of biogenic volatile organic compounds (BVOCs) play important roles in ecophysiology and atmospheric chemistry at large spatial and temporal scales. Tropical regions are a main global source of BVOCs and magnitude and chemical compositions are highly variable. This study is based on the measurements of monoterpenes using proton transfer reaction-time of flight-mass spectrometer (PTR-TOF-MS) at a semi-arid site in western India during the winter-to-summer transition. Mixing ratio of monoterpenes showed strong diurnal variation with elevated values from evening till midnight and lowest in the afternoon. The daily data does not show clear trends with monthly means of ~ 0.35 ppbv during each month. Exceptionally high levels of 3–6 ppbv were measured during the sporadic biomass burning and bonfire event during Holi festival. The daytime data of monoterpenes do not clearly reflect the impact of biogenic emission due to the competing influences of mixing and OH-reaction loss. In the afternoon, the monoterpenes/benzene ratio of 0.43 ppbv ppbv−1 in second half of March was ~ 3 times higher than that in first half of February. It showed strong response with temperature as it increased from 0.27 ppbv ppbv−1 ( 30 °C). The dependence with wind speed is represented by exponential decay but rate of decline in February was ~ 2 times greater than that in March. The ratios of monoterpenes/isoprene in the night were significant higher than those during the day indicating light independent but temperature dependent emissions of monoterpenes. The nighttime MTs/isoprene ratio increased from 0.25 ppbv ppbv−1 in the first half of February to 0.43 ppbv ppbv−1 in the second half of March. Overall, the ratios of monoterpenes/isoprene agree with the values reported for a topical forest region in SE Asia. The estimated contribution from local biogenic sources to ambient monoterpenes increased from 31 % in first half of February to 67 % in second half of March. This trend suggests the increasing biogenic contribution from February to March. The NW winds and higher ambient temperatures in March favored the local emissions and regional transport of BVOCs.
