Influence of seasonality on macroinvertebrate diversity associated with the aquatic fern Salvinia biloba Raddi
Authors: Coutinho Rennan Leite Martins , Lancellotti Isabella Rodrigues , Flores Arthur Ribeiro , Santos Marcelo Guerra
Published: April 2020

Abstract. The genus Salvinia is composed of fast-growing floating ferns, capable of surviving in different environmental conditions. Some authors suggest that the relationships between this genus and macroinvertebrates may serve as water quality indicators. The present study aimed to determine the influence of seasonality and water quality on macroinvertebrate diversity associated with the Salvinia biloba Raddi. Water and fern were collected in rainy and dry seasons and was conducted a microbiological analysis of the water, as well as, the area of fern cover on the water, richness, and density of macroinvertebrates. Microbiological analysis of the water detected > 5,700 CFU/mL (rainy season) and 175 CFU/mL (dry season) of heterotrophic bacteria and was positive for total thermotolerant coliforms. The S. biloba cover on the water surface was 100% in the rainy and 30% in the dry season. In the rainy season, 142 macroinvertebrates were identified, divided into 12 morphospecies, with a density of 434 individuals/m3. In the dry season, there were 419 individuals in 14 morphospecies, with a density of 2,076 individuals/m3 exhibited. The highest species density recorded in the rainy season was for Chironomidae sp.1 (Diptera) (57.71%) and Odonata Zygoptera sp.1 (17.44%), and in the dry season, Chironomidae sp.2 (73.98%) followed by Gerromorpha sp.1 (Hemiptera), with 9.54%. The Sørensen similarity index between the two seasons was 53.84%. The higher density of Gerromorpha sp.1 in the dry season may indicate an increase in environmental integrity.
"Naszą filologiczną ojczyzną jest ziemia…" Jak "amerykańska" komparatystyka wyobraża sobie obywatelstwo w nowym świecie?

"Our Philological Home Is the Earth…" How Do “American” Comparative Studies Imagine Citizenship?
In 1952, Erich Auerbach, an exile and author of a seminal comparative project, announced that our philological home is the earth: it can no longer be the nation. His words seem both valid and timely in the contemporary global rise of neo-nationalism, anti-democratic movements, as well as the backlash against women’s and minorities’ emancipation. Since its beginnings, the comparative literature has been envisioned not only as an academic discipline that studies literature beyond national borders, but also a remedy against xenophobia and intolerance. This paper presents how the contemporary comparative theories depict citizenship, one of central identities in modern multicultural societies. Adopting a postcolonial approach, I examine three projects developed within “American” Comparative Studies: Mary Louise Pratt’s “comparative cultural practice”, Gayatri Spivak’s “planetarism”, and Jessica Berman’s “trans critical optic”.

Primate Stefan Wyszyński’s Attitude towards the Apparent Normalization of State-church Relations in the First Years of Edward Gierek’s Rule (1971-1974)
The article describes primate Wyszyński’s view on the political situation in the Polish People’s Republic during the period of 1971-1974. It contains his attitude to the political system, communist ideology, and negotiations between the Holy See and the government of the Polish People’s Republic. Primate Wyszyński was a political visionary, who had a very realistic view on the political situation in Poland. It was visible in his relation to the normalization, which the authorities declared in the first part of Edward Gierek’s decade.
Specter of Globalization: Marx, Gramsci and Disjointed Time
Authors: Bina Cyrus
Published: April 2020

This paper aims to combine a critique of political economy with that of transnational polity in a unified theoretical foundation. It begins by (1) exploring the development of capitalism into stages, (2) showing that this should necessarily lead to globalization, and (3) validating that in the epoch of globalization no hierarchical interstate (hegemonic or not) political order may stand a chance for survival. These highly abstract theoretical queries, on the one hand, follow Karl Marx's critique of capitalism, and on the other hand obtain further theoretical and historical concretization in Antonio gramsci's hegemony, before their realization at observable levels via the rise and fall of the postwar Pax Americana (1945–1979). Marx's “conquest of mode of production” and gramsci's hegemony set the context for a synthetic approach to the rise and fall of American power. Finally, the force of globalization is the arbiter of time, despite the declining power syndrome, in this disjointed polity.
The topology of welfare–migration–asylum: Britain’s outsiders inside
Authors: Morris Lydia D.
Published: April 2020

Starting from the observation that recent immigration controls seem ‘hewn from the same rock’ as the welfare reforms, this article seeks to identify commonalities of approach, technique and effect across both fields. These can usefully be viewed through the concept of topology – a process of folding and filtering that challenges clear distinctions between inclusion and exclusion. Alongside a stratified system of rights based on conceptions of desert and apparent in both the welfare and migration/asylum systems, we find overlapping features that emerge from a harnessing of rights in the name of controls, and increasingly affect both citizens and non-citizens alike.

Experimental investigation of a time-power transformation method for flash-pulse thermographic testing
Authors: Muzika L. , Švantner M. , Moskal D.
Published: April 2020

The paper deals with flash-pulse thermography, which is one of the most used thermographic inspection methods. The method is based on flash excitation of an inspected object and an analysis of its thermal response recorded by an infrared camera. This paper deals with a time-power transformation method (P-function) for an evaluation of the flash-pulse thermography measurement. The method is based on a transformation of the measured thermal response using a power function of time. An adaptation of the method is introduced, and an experimental investigation of the method is presented. The method and the evaluation procedure are described. A flash-pulse inspection of an experimental sample is performed, and the results of the inspection obtained by the P-function method and by a fast Fourier transform evaluation are compared using a contrast-to-noise ratio ranking. Advantages of the P-function method resulting from its numerical outputs for an estimation of the depth of defects are described. An influence of noise reduction and data preprocessing is discussed.

The CA-DMFSH-assisted structure shows great potential for enlarging the effective index difference, and the proposed fiber targets applications in the short-reach space-division multiplexing optical networking while eliminating the complex multi-input/multi-output digital signal processing.
Label-free assessment of hemodynamics in individual cortical brain vessels using third harmonic generation microscopy
Authors: Ahn Sung Ji , Ruiz-Uribe Nancy E. , Li Baoqiang , Porter Jason , Sakadzic Sava , Schaffer Chris B.
Published: April 2020

We show that third harmonic generation (THG) microscopy using a 1-MHz train of 1,300-nm femtosecond duration laser pulses enabled visualization of the structure and quantification of flow speed in the cortical microvascular network of mice to a depth of > 1 mm. Simultaneous three-photon imaging of an intravascular fluorescent tracer enabled us to quantify the cell free layer thickness. Using the label-free imaging capability of THG, we measured flow speed in different types of vessels with and without the presence of an intravascular tracer conjugated to a high molecular weight dextran (2 MDa FITC-dextran, 5% w/v in saline, 100 µl). We found a ∼20% decrease in flow speeds in arterioles and venules due to the dextran-conjugated FITC, which we confirmed with Doppler optical coherence tomography. Capillary flow speeds did not change, although we saw a ∼7% decrease in red blood cell flux with dextran-conjugated FITC injection.

Nonlinear wavefront reconstruction with convolutional neural networks for Fourier-based wavefront sensors
Authors: Landman R. , Haffert S. Y.
Published: April 2020

Fourier-based wavefront sensors, such as the Pyramid Wavefront Sensor (PWFS), are the current preference for high contrast imaging due to their high sensitivity. However, these wavefront sensors have intrinsic nonlinearities that constrain the range where conventional linear reconstruction methods can be used to accurately estimate the incoming wavefront aberrations. We propose to use Convolutional Neural Networks (CNNs) for the nonlinear reconstruction of the wavefront sensor measurements. It is demonstrated that a CNN can be used to accurately reconstruct the nonlinearities in both simulations and a lab implementation. We show that solely using a CNN for the reconstruction leads to suboptimal closed loop performance under simulated atmospheric turbulence. However, it is demonstrated that using a CNN to estimate the nonlinear error term on top of a linear model results in an improved effective dynamic range of a simulated adaptive optics system. The larger effective dynamic range results in a higher Strehl ratio under conditions where the nonlinear error is relevant. This will allow the current and future generation of large astronomical telescopes to work in a wider range of atmospheric conditions and therefore reduce costly downtime of such facilities.

We demonstrate sub-micrometer processing of two kinds of thin films, polymethyl methacrylate (PMMA) and metal nano-particle resist, by focusing high-order harmonics of near-IR femtosecond laser pulses in the extreme ultraviolet (XUV) wavelength region (27.2–34.3 nm) on the thin film samples using an ellipsoidal focusing mirror. The ablation threshold fluences for the PMMA sample and the metal nano-particle resist per XUV pulse obtained by the accumulation of 200 XUV pulses were determined to be

Disclosing transverse spin angular momentum of surface plasmon polaritons through independent spatiotemporal imaging of its in-plane and out-of-plane electric field components
Authors: Qin Yulu , Ji Boyu , Song Xiaowei , Lin Jingquan
Published: April 2020

The comprehensive capture of near-field spatiotemporal information of surface plasmon polaritons (SPPs) is a prerequisite for revealing their physical nature. In this study, we first performed an independent, spatiotemporal imaging of the out-of-plane and in-plane components of SPP near-fields in a femtosecond light-excited trench using an obliquely incident time-resolved photoemission electron microscopy (TR-PEEM). We did the capture by imaging of the interference patterns induced by a superposition of the

-polarized probe light, with the out-plane or in-plane components of SPP near-fields, under the noncollinear excitation mode. The method may be used to reconstruct a 3D SPP spatiotemporal field. Moreover, we demonstrated that the fringe shift of the interference patterns between the captured in-plane and out-of-plane components of the SPP field in PEEM images corresponds to the 1/4 fringe period, which is attributed to

out of phase of the out-of-plane and in-plane near-field components of SPP. The resulting TR-PEEM images are supported by a classical wave mode and FDTD simulations. Essentially, the measured

phase difference between the in-plane and out-of-plane components of the SPP indicated a rotating field component in the propagation plane, i.e., that the SPP exhibits an elliptically polarized electric field in the propagation plane. The experimental results presented herein provide direct evidence of SPP having the inherent attributes of transverse spin angular momentum.

With the recent development of the metasurface, generating an optical vortex in optical far or near fields is realized in various ways. However, to generate vortices in both the near and far fields simultaneously is still a challenge, although it has great potential in the future compact and versatile photonic system. Here, a bi-channel optical vortex generator in both the near and far fields is proposed and demonstrated within a single metasurface, where the surface plasmon vortex and the far-field optical vortex can be simultaneously generated under circularly polarized light. The ability of generating vortices with arbitrary topological charges is experimentally demonstrated, which agrees well with simulations. This approach provides great freedom to integrate different vortex generators in a single device and offers new opportunities for integrated optical communications, trapping, and other related fields.

Published: April 2020

Eine große Bedrohung für die Informationssicherheit geht von Mitarbeitern aus, die absichtlich der eigenen Organisation schaden wollen. Mitarbeiter besitzen Zugriffsrechte für sensible Informationen und genießen das Vertrauen des Unternehmens. Werden sie allerdings aufgrund persönlicher Motive oder äußerer Umstände zu Whistleblowern, Spionen, Betrügern, Saboteuren, Malicious Enablern oder Datendieben, können sie großen Schaden anrichten. Dieser Artikel untersucht die Motive sogenannter Malicious Insider und stellt die sechs verschiedenen Typen anhand von realen Beispielen der jüngeren Vergangenheit vor. Er zeigt, welche erkennenden, präventiven und reaktiven Maßnahmen Organisationen ergreifen sollten, um die Risiken durch Attacken von böswilligen Insidern zu minimieren. Der Fokus liegt auf den erkennenden Maßnahmen. Durch frühzeitiges Eingreifen werden Mitarbeiter gar nicht erst zu Malicious Insidern. Eine Kombination aus persönlicher Veranlagung (z. B. Introversion, Gier, Kritikunfähigkeit), Stressfaktoren (z. B. Frustration, Unzufriedenheit) und auffälligem Verhalten (z. B. außergewöhnliche Arbeitszeiten oder Reiseziele) weist häufig auf potentielle Täter hin.
Digital interventions in drama therapy offer a virtual playspace but also raise concern

Published: April 2020

This special issue was assembled before the height of the COVID-19 pandemic. Recent measures involving social distancing encouraged by the World Health Organization and national governments have necessitated an unprecedented shift to online platforms for nearly all spheres of social life including work, schooling and healthcare. Drama therapists who have been offering services online have been generous in sharing insights, drama therapy educators have been collaborating on ways of translating training, and digital venues for therapeutic performance have emerged. Necessity is indeed the mother of invention. We have much work ahead of us but the creativity, spontaneity, playfulness and commitment of this community to accessible and effective care will take us forward. It is our hope at DTR that this issue might offer additional insights and resources to meet the needs of these times.

The aim of this paper is estimate the (co)variances components in the genetic parameters to the growth traits in Nelore Mocho cattle, raised in Cerrado biome, using Bayesian statistics. The information obtained from 48,063 cattle, provenient of Nelore Mocho herd, born from 1987 to 2009, participant of Breeder and Research Nacional Association's (ANCP) Nelore Brazil Program. The standard weight in 120 (P120), 210 (P210), 365 (P365), 450 (P450) years old has been evaluated, the weight gain from the birth to the weaning (GPND) and the weight gain from weaning to yearling (GPDS). The (co)variances components and genetic parameters have been estimated under univariate analyses considering the Bayesian statistics animal model by the MTGSAM (Multiple Trait using Gibbs Sampler under Animal Model). The estimated values to direct heritability were from medium to high magnitude in standard weights (0.23 to 0.33) and the weight gain (0.18 and 0.24), in creates and recreates phase, respectively. These results indicate the genetic variability existence in Nelore Mocho herd to growth traits, showing effective genetic growth when using the direct selection of these features in genetic improvement programs.

American Tegumentary Leishmaniasis (ATL) is a widely distributed anthropozoonosis caused by theprotozoa Leishmania spp. and is considered a serious public health problem. We aimed to assessManhuaçu’s burden caused by ATL through the profiling of all ATL case reports during the period from2010 to 2015. A descriptive, ecological and retrospective study of the confirmed cases of ATL wascarried out using data regarding the age, sex, area of residence, type of entry (new case or recurrence),and clinical form of the disease of the existing registered reports provided by the Sistema de Informaçãode Agravos de Notificação (SINAN). We observed that the first quarter of the years showed highernumber of reports. The 58 notifications were classified as a first time occurrence, being 95% of thecutaneous form of the disease, and 76% of the cases in male patients. Regarding the location of theinfection, 86% of the patients belonged to the rural area, and most (60%) were between 20 and 59 yearsold. Thus, the epidemiological profile of infections of ATL in Manhuaçu, MG indicates that maleindividuals aged between 20 and 59 years old and living in rural areas are more likely to get infected.Moreover, it is important to know the epidemiological profile of ATL cases for adequate healthsurveillance and prevention of the disease on this region.
Analysis of Body Posture using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) to Improve the Posture of Sand Paper Machine Operators and Reduce the Risk of Low Back Pain
Authors: Kusuma Trio Yonathan Teja
Published: April 2020

The metal casting industry, Nitikan is a micro business whose production process is carried out manually. The equipment used is simple and without considering the user's health. This can be seen in the product finishing process that uses a sanding machine. The equipment is not designed according to the user's posture so the operator bends in doing work movements, of course this is very risky to experience lower back pain injuries. This study aims to analyze the work activities of the finishing process using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) approach and design work tools that can be applied to improve work posture. The results of data processing and analysis obtained a Rapid Entire Body Assessment score on a sandpaper machine single head of 5 and a Rapid Upper Limb Assessment score of 4, the score indicates that the work position has the potential to experience a risk of low back pain, so there must be an improvement in work posture. Work posture improvement is done by designing a tool in the form of a sandpaper machine that takes into account ergonomic dimensions to reduce the risk of lower back injury. The final result after the improvement is obtained Rapid Entire Body Assessment score of 3 and Rapid Upper Limb Assessment score of 4. This shows that the risk of lower back injuries can be minimized.
A (mush)room of one’s own: feminism, posthumanism and race in Sofia Coppola’s The Beguiled
Authors: Brown William
Published: April 2020

The Beguiled (Sofia Coppola, USA, 2017) is one of several recent films to feature mushrooms as a prominent plot device. In this essay, I argue that the use of mushrooms here allows cinema to engage with issues surrounding the Anthropocene, or the period in which capitalist man has shaped the world more than the world has shaped capitalist man. I shall in particular propose that the association between women and fungi suggests that the Anthropocene entails an anthropocentric and patriarchal worldview. That is, The Beguiledsuggests that the Anthropocene is defined specifically by capitalist man – whose world must now be replaced by one that might be deemed feminist and posthuman, not least because of how the women at the film’s all-girls’ private school work with mushrooms to bring down the central male figure, Civil War soldier Corporal John McBurney.
However, The Beguiled also posits the limits of such a feminist and posthuman world. For despite the film’s Civil War setting, and despite its status as a remake-cum-adaptation of both Don Siegel’s 1971 film of the same name and Thomas P. Cullinan’s source novel, the film only deals with race as at best a structuring absence. Coppola’s (characteristic) refusal to deal directly with race nonetheless allows us to identify the whiteness of those wider issues with which the film deals, namely the Anthropocene, posthumanism, (much) feminism and perhaps cinema itself. In particular, we can draw out this latter suggestion by considering the film’s use of the Madewood Plantation House, which also features in music videos for artists like J. Cole and Beyoncé. For if cinema is a force for the white Anthropocene, it is perhaps in supposedly “unruly” media outside of cinema that black and other feminisms can intersect with posthumanism to emerge as a genuine alternative to the Anthropocene.

Nesse sentido, busca-se ler o espaço fílmico em conjunto com esses padrões de movimento e, portanto, em uma consideração histórica e sócio-geográfica da paisagem representada. Desse modo, reconhecendo, em uma materialização fílmica comum, corpo, paisagem e movimento.
A Nova Inglaterra como paisagem para o horror feminino em A Bruxa
Authors: Canepa Laura Loguercio , Carreiro Rodrigo
Published: April 2020

Este artigo tem o objetivo de realizar uma análise do filme A Bruxa (Robert Eggers, EUA, 2015), a fim de demonstrar como o tema da busca de autonomia feminina em uma sociedade cristã fundamentalista, no espaço ao mesmo tempo selvagem e inóspito da Nova Inglaterra, constrói, conduz e modula as convenções do horror dentro dessa narrativa. Para tal, examinaremos, primeiramente, de que maneira o contexto histórico e religioso dos EUA do século XVII produzia famílias incapazes de lidar com a ideia de autonomia feminina, vista como não natural – e, portanto, potencialmente sobrenatural. Também discutiremos brevemente como o processo histórico estadunidense dos séculos XVII e XVIII originou uma longa tradição de narrativas de horror passadas na região da Nova Inglaterra, às quais o filme A Bruxa também está relacionado.

Published: April 2020

O artigo apresenta um panorama das principais produções cinematográficas realizadas por mulheres negras brasileiras e de como suas obras se constituem no conceito de Cinema Negro no Feminino. Reflete sobre o caráter ideológico de gênero e raça e do processo feminino de identidade negra no cinema. Observa-se que ao produzirem e dirigirem filmes, as mulheres negras edificam o cinema como espaço de pertencimento e de referência da história e da cultura negra. Seus trabalhos têm possibilitado leitura afetiva, política e geográfica, e constroem uma cinematografia fora da estereotipia, descortinando novas visões de mundo, em que o cinema é entendido como espaço de identidades, manifestações, expressões e cidadania. Constata-se que o cinema produzido por mulheres negras tem marcado uma territorialidade sedimentada no desenvolvimento humano, criando e recriando mundos e possibilidades de amor e afetos.

Enabling students to articulate the value of language skills in an ever-changing work environment
Authors: Campbell Caroline
Published: April 2020

This paper shares some of the findings of an evaluative research project funded by the Leeds Institute of Teaching Excellence (Brown et al., 2018). The project explored the value of ‘Broadening’ as part of the Leeds Curriculum and the value of language learning in the context of Institution-Wide Language Provision (IWLP). The paper focuses on the data gathered from interviews with employers and presents the findings around employer expectations of graduates and their perceptions of the value of language skills and cultural awareness. It considers how to enable students to articulate the knowledge, skills, and experience gained during their undergraduate journey. It identifies the value of language skills beyond linguistic competence and maps this to employer expectations. It proposes an end-of-module reflective task for any language module to enable students to articulate their personal ‘brand’ based on their knowledge and social capital, thus evidencing the breadth of their employability.
Barbara Hammer's Jane Brakhage
Authors: Peterson Jennifer
Published: April 2020

This essay analyzes Barbara Hammer's 1974 experimental nonfiction film Jane Brakhage. Both an homage and a rebuttal to the many films of Jane Brakhage made by her husband, Stan Brakhage, Hammer's film gives Jane the voice she never had in Stan's work. The article contextualizes Jane Brakhage's production at a moment when competing strands of feminist thought took different approaches to the fraught topic of nature. Hammer's films were criticized as essentialist by feminists in the 1980s, but this essay argues that Jane Brakhage complicates that reading of Hammer's work. The film documents Jane's creative life in the mountains, but critiques the limitations of her role as a heterosexual wife and mother. By locating this short film within a larger genealogy of feminist and environmental thought, we can better appreciate the extent to which Hammer's films explore the feminist and queer potential of nature.
Social Justice and Critical/Performative Communicative Pedagogy
Authors: Warren John T.
Published: April 2020

Through narratives and critical interrogations of classroom interactions, I sketch an argument for a co-constitutive relationship between qualitative research and pedagogy that imagines a more reflexive and socially just world. Through story, one comes to see an interplay between one's own experiences, one's own desires and one's community — I seek to focus that potential into an embodied pedagogy that highlights power and, as a result, holds all of us accountable for our own situated-ness in systems of power in ways that grant us potential places from which to enact change. Key in this discussion is a careful analytical point of view for seeing the world and a set of practices that work to imagine new ways of talking back.
Collage Journaling with Pre-service Teachers
Authors: Lewis P.J.
Published: April 2020

Students in a B.Ed. program take a Language Arts course and in an effort to suggest “alternative” ways of exploring the ‘content’ students were asked to make collage journals. They were encouraged to explore the process and product of making art, which sees a constant movement between the two, a vacillation between process and product through the creative act. This multi-media presentation uses the storyteller-researcher's voice to knit the narrative together, however, it is the visual and textual voices of the students which emerge, creating a multi-vocal story of meaning-making for all. Readers may view and listen to a performance of the work at: http://education.uregina.ca/web/lewis20p/IRQR/ . In order to view some of the collage journals created by the students in this research project readers will need to use the URL provided.
Narrating Confluent Experiences in a Child Welfare Case
Authors: Latty Christopher R. , Burns-Jager Kathleen
Published: April 2020

This constructed narrative inquiry illustrates confluent stories of a young mother, Jenny, charged with child abuse and neglect; her foster care case worker, Rachel; and her therapist, Kathleen. As researchers, we discuss the positions of each person: mother, caseworker, therapist through storied fragments representing what is most important in how they came to understand the process of their year-long work together that led to Jenny's releasing her parental rights. Layering interviews and reflexive writings, we focus on decision-making and voice; about what it means to be a parent, a foster care worker, and a therapist in a community context where parent benefit from services and the child's best interest is a privileged societal discourse.
The Veil of Esteem
Authors: Hoffer Melba
Published: April 2020

This essay is the first of a three-part series entitled: The Veil of Esteem: On Seeing Oneself Being Seen. Inspired by Walter Benjamin's “reflection through vignette” method, I inquire into the notions and interconnections between memory and esteem. Esteem is the truth of oneself through the eyes of the other, and any truth of esteem must be told from the perspective of that other, through the spectating other. Thus, I find that any story of esteem is veiled. This first part, Fragment/Never Thinking of Tomorrow, interrogates the role of fiction as a necessary component of the practice of memorialization. The story is narrated not as a representation of a person or of people, but the discourse through which I have been lent her voice. I am the translator through which she is now speaking. The translator is the producer of the discourse that suffocates her and allows her to breathe in gasped breaths, the producer of the discourse that both takes away her voice and gives her voice. The second part of this series, Riddle and Accident, appears in Cultural Studies ⇔ Critical Methodologies Volume 12, Issue 2; the third part, A Loan, appears in Qualitative Inquiry Volume 18, Issue 4.

Published: April 2020

Background: Unexpected events in cardiac surgery may increase morbidity and mortality. We present rare complications related to coronary arteries in non-coronary cardiac surgery in adults and pediatrics.
Patients and Methods: We retrospectively reviewed our surgical left-sided valve procedures and aortic root reconstruction for patients with documented coronary ostial injury or left circumflex artery (LCX) between January 2012 and December 2019.
Preoperative echocardiography was the standard investigation for all cases and other specific work ups were ordered, according to each case. Management by surgical or non-surgical intervention was planned, according to each complication. Postoperative hemodynamics and mortality rate were the outcomes of interest.
Results: Seven patients were found to have coronary artery compromise post left-sided valve procedures and aortic root reconstruction in adults and children. The details are shown in Table 1. The complications were in 2 patients post-mitral valve (MV) repair, 3 patients post-aortic (AV) replacement, 2 pediatric patients, 1 post-aortic homograft, and the other post-repair of anomalous single coronary arising from the pulmonary artery (ASCAPA). Six patients were hemodynamically unstable. Five patients had intraoperative ischemic changes on electrocardiogram and echocardiography, while ventricular arrhythmias were documented in 3 patients. Two patients were treated with percutaneous coronary intervention to LCX and right coronary artery (RCA), while 4 patients required immediate surgery to graft the obtuse marginal branch of the LCX artery (1) and RCA (3). No revision to valvular procedure was done. With the exception of one, all patients survived.
Conclusion: A high index of suspicion is required to diagnose and rescue coronary complications post-valvular surgery and aortic root reconstruction.
The Moderating Effect of Fuel Prices on the Market Value of Fuel Economy, Driving Intensity, and CO2 Emissions
Authors: Pleshcheva Vlada , Klapper Daniel
Published: April 2020

In this paper, we explore co-movements of the vehicle price sensitivity to fuel economy with changes in fuel prices. Previous literature has investigated the responsiveness of vehicle prices to fuel prices or fuel economy. We are interested in the interaction effect of fuel prices and fuel economy and answer the question of how exactly the market value of fuel economy depends on the fuel price. By looking at the role of fuel prices as a moderator for the market value of fuel economy, we are able to differentiate between consumers’ valuation of fuel economy versus their reaction to changes in fuel prices. We apply a hedonic price model to the German automobile market by using data on detailed technical specifications of high-sales vehicles of three consecutive model years. In contrast to previous research, where the marginal benefits of driving a car with a particular fuel economy remained constant, we allow it to vary with fuel prices. It enables us to investigate two sources of changes in the market value for fuel economy. The first source, as in the previous studies, corresponds to changes in the budget for driving a car, whereas the second source reflects changes in the capital investments in a better fuel economy. The total effect of these two sources may lead to either a decrease or an increase in the vehicle distance traveled. We study the differences in the impact of fuel prices for various car makes of both diesel and gasoline engines. Our results suggest that there are substantial differences in the market values of fuel economy between diesel and gasoline vehicles and their responsiveness to changes in fuel prices. Diesel cars are characterized by the more elastic price gradient of fuel economy to fuel prices compared to gasoline cars. The revealed high responsiveness of the market value of fuel economy to fuel prices results in an optimal annual driving intensity that is an increasing function of fuel prices. It implies that, during the period of investigation, the marginal benefit of driving a car of a specific fuel economy was higher than the corresponding fuel price effect on the budget for driving. Using the quantified impact of fuel prices on the market value of fuel economy, we also assess the implied changes in the kilometers driven with cars and the resulting CO2 emissions. The current study presents an empirical application of statistical analysis to a topic of interest to readers in the areas of quantitative economics and economic policy.

Published: April 2020

As pesquisas clínicas relacionadas a COVID-19 estão acontecendo em todo o mundo, inclusive no Brasil. Os registros públicos de protocolos de pesquisa promovem transparência e atendem às regulamentações. Objetivo: Descrever os protocolos de pesquisa em desenvolvimento no Brasil para investigações de alternativas terapêuticas para a COVID-19, e avaliar o cumprimento da publicação após registro na Plataforma Brasil/CONEP. Método: Uma revisão foi realizada nas bases de registro de protocolos de pesquisa: ClinicalTrials.gov,  ReBEC (base brasileira) e International Clinical Trials Registry Platform, no dia 11 de abril de 2020. O boletim da CONEP do dia 07 de abril de 2020 foi consultado para avaliar estudos de intervenção passíveis de registro. Resultados: Nosso estudo mostrou que há dezesseis estudos de intervenção sobre a COVID-19 em andamento no Brasil e registrados na CONEP, porém somente seis estão disponíveis nas bases de registro de protocolos. Os protocolos brasileiros de acesso aberto incluíram a investigação de intervenções com: hidroxicloroquina associada a azitromicina ou em monoterapia; cloroquina; dexametasona; células tronco mesenquimais. Cinco estudos (83%) são abertos e incluíram pacientes com suspeita ou diagnóstico confirmado da COVID-19. Três estudos são multicêntricos e todos propõe a avaliação de desfechos clinicamente relevantes. Conclusão: O Brasil tem protocolos de pesquisa em andamento de intervenções terapêuticas na COVID-19, porém apenas 1/3 destes estudos têm protocolos públicos.
A general view of the biomass energy potential and its use in Turkey
Authors: Guresci Ertugrul
Published: April 2020

Biomass energy is an important energy source in Turkey. In particular, it is the major source of energy in rural Turkey. Biomass energy is used to meet a variety of energy needs, including heating homes and workplaces, generating electricity, fuelling motor vehicles and heating processes for industrial production. Biomass energy sources include forest production, and animal and plant wastes. Because the output value is rather high in Turkey and about 27.6% of the total share of biomass production, fuel wood is an important source of biomass energy. The total biomass energy potential in Turkey is about 32.4 Mtoe (million tonnes of oil equivalent). The amount of usable biomass potential in Turkey is approximately 17.2 Mtoe. This study describes the situation and importance of biomass energy production, its use and potential in Turkey. The current status of biomass energy and requirements for biomass energy production, which play an important and vital role in human life, the environment and agriculture, have been examined.
