La formación docente inicial del profesor de Historia en Brasil: temas, reflexiones y desafíos
Authors: Cavalcanti Erinaldo
Published: March 2021

Existe un consenso relativo en la bibliografía especializada sobre el hecho de que el libro de texto sigue siendo una poderosa herramienta de trabajo de los docentes de la educación primaria y secundaria enBrasil. Debido a las dimensiones geográficas de Brasil, este artículo hace un recorte y analiza los diseños curriculares de las carreras de grado en Historia ofrecidos en universidades federales en la región amazónica de Brasil para comprender cómo los libros de texto son analizados durante el período de formación inicial de los docentes. Como opción metodológica, se procedió al análisis cuantitativo y cualitativo de las matrices curriculares de los cursos ofrecidos en las universidades federales de la región amazónica de Brasil. Se analizó el lugar que ocupa la enseñanza de la historia en estas universidades y, de manera específica, el papel que juega el debate sobre el libro de texto de historia en las referidas carreras de grado. Para ello, fueron analizadas las asignaturas obligatorias dedicadas al estudio de la enseñanza de historia: los libros de texto, sus objetivos y sus cargas horarias. El análisis muestra que, en los grados estudiados, la división clásica de temas prevalece en el modelo eurocéntrico cuadripartito y que no hay consenso sobre el lugar que ocupa el debate sobre la enseñanza de la historia. Además, se identifica una ausencia casi completa de estudios sobre libros de texto.

Identidade, uma memória a ser enfrentada
Authors: Bulhões Maria Amélia
Published: March 2021

O artigo analisa a tarefa da arte e da psicanálise nos agenciamentos da memória e das identidades. Reconhece a globalização como um regime cuja temporalidade e forma de comunicação rompe com as territorialidades, funcionando, por sua vez, contrariamente à produção de identidades mais críticas e pluralistas. Analisa o trabalho de três artistas contemporâneos que elaboram problemáticas relacionadas à memória, história, silenciamentos e colonialismo.  Abstract The article analyzes the task of art and psychoanalysis in the agency of memory and identities. It recognizes globalization as a regime whose temporality and form of communication breaks out territorialities, functioning, in turn, contrary to the production of more critical and pluralistic identities. It analyzes the work of three contemporary artists who elaborate issues related to memory, history, silences and colonialism.
POSSIBILIDADES DO EQUÍVOCO: A TRADUÇÃO DO PASSADO NO TEXTO AUTOBIOGRÁFICO
Authors: Dias Leandro De Bona , Bressan Júnior Mário Abel
Published: March 2021

A partir do conceito de equivocidade controlada (VIVEIROS DE CASTRO, 2018), o artigo apresenta a tese de que na escrita literária autobiográfica ocorre uma tradução via equívoco de memória. Há, portanto, o que ocorreu, o que é enunciado sobre isso, e o resultado é uma terceira coisa que surge da diferença entre esses dois movimentos: o equívoco de memória. Partindo desse pressuposto e compreendendo a literatura e a ficção como elementos que compõem a realidade (CANDIDO, 2011, 2006; HALL, 2003, BAKHTIN, 2011), propõe-se uma discussão acerca do entrelaçamento entre a linguagem literária e a memória (LE BRETON, 2009; HALBWACHS, 1990) a fim de apresentar as bases para o desenvolvimento do equívoco de memória, conceito ainda em construção.
A METAMORFOSE DE CLARICE LISPECTOR
Authors: Ferreira Ermelinda Maria Araújo
Published: March 2021

A obra de Clarice Lispector sofre uma guinada a partir dos anos 1960, com o livro de contos Laços de família, escrito durante sua experiência profissional como jornalista responsável pelas colunas femininas publicadas na imprensa carioca nesta década. A menção obsessiva à receita “Como matar baratas” nessas páginas, que vem a dar origem ao conto “A quinta história”, e posteriormente ao romance A paixão segundo G. H., revela que a autora terá vislumbrado na figura do inseto um potencial capaz de deflagar uma reflexão metalinguística sobre o processo de metamorfose de seu estilo, após a sua prática como cronista.
PERTO DO CORAÇÃO DA ÁGUA VIVA
Authors: Sobral Ayanne , Castello Branco Lucia
Published: March 2021

Nesse ano de 2020, em que Clarice Lispector faria 100 anos, partimos de seu primeiro romance, Perto do coração selvagem, publicado em 1943. Neste romance, é possível pensar o feminino não como uma referência simétrica e complementar ao masculino, mas como um “mais além” do falo e do próprio masculino,  já se delineando aí o que, para nós, na Literatura e na Psicanálise, é ainda uma novidade: o feminino de ninguém, que se abre a um outro campo, terceiro campo, terceira via, terceira margem do rio: ao terceiro sexo da paisagem. Neste artigo, o terceiro sexo é localizado sobretudo em Água viva, livro de 1973, em que A mulher, aquela que não existe, pode enfim ex-sistir como substantivo feminino de ninguém. Assim, entre as criaturas humanas, vegetais e animais, pudemos enfim nos aproximar do lugar de onde Clarice sempre escreveu: perto do coração da água viva.
MULHERES INVISÍVEIS EM A HORA DA ESTRELA, DE CLARICE LISPECTOR E EM DOIS IRMÃOS, DE MILTON HATOUM: MACABÉA E DOMINGAS
Authors: Brito Santana Josué , Fonseca Andrade Maria das Graças
Published: March 2021

Este artigo pretende aproximar as personagens Macabéa, da novela A hora da estrela (1977), de Clarice Lispector, e Domingas, do romance Dois irmãos (2000), de Milton Hatoum, tendo em vista a emergência da discussão sobre a invisibilidade da mulher enquanto construção social. Macabéa é mulher nordestina, pobre, feia, retirante, semianalfabeta, virgem e datilógrafa, que migra para o Rio de Janeiro e lá sofre preconceito e violência por estar fora dos atributos requeridos pela cidade grande. Domingas é mulher indígena, vítima de vários tipos de violência e ignorada em sua singularidade. Duas histórias que atravessam o tempo e o espaço e que refletem a desigualdade social brasileira e os desafios para a superação da condição de subalternidade da mulher. Alguns pensadores como: Michelle Perrot (2007), Alfredo Bosi (1981), Ecléa Bosi (2006), Antônio Cândido (2011), Stuart Mill (2006), Quijano (2005) e outros nos ajudarão a refletir sobre essas questões.

Authors: Almeida Gislene Lima , Soares Cláudia Vivien Carvalho de Oliveira
Published: March 2021

Neste artigo, analisamos um estudo de caso em que o objetivo principal foi investigar se/como as tecnologias digitais aliadas à música podem contribuir e/ou potencializar a aprendizagem de Língua Inglesa (LI) de alunos do ensino médio da rede pública de ensino, no que se refere à compreensão auditiva de inglês. Desse modo, neste estudo, a qual se insere nos pressupostos da linguística aplicada, e cujos arcabouços metodológicos estão pautados na pesquisa qualitativa, propusemos aos sujeitos uma sequência didática (DOLZ; SCHNEUWLY, 2013) com o gênero música, com vistas à prática da compreensão auditiva através do Lyrics Training, interface digital voltada para a aquisição de línguas por meio da convergência de mídias. Como arcabouço teórico, nos baseamos, principalmente, em Berk (2008), Braga (2007), Leffa (2016), Santaella (2011 e 2014) e Santos e Rossini, (2011).Nessa perspectiva, a análise dos resultados e das observações empreendidas durante todo o período de desenvolvimento do estudo indica que as tecnologias digitais alinhadas a atividades com músicas podem trazer contribuições relevantes para a aprendizagem de inglês ao passo que propiciam a prática de habilidades linguísticas, principalmente no que diz respeito à compreensão auditiva. Ademais, as experiências vivenciadas mostraram que a utilização desses recursos no fazer pedagógico pode significar importantes mudanças para o processo de aprendizagem de LI.

Photoelastic Stress Response of Complex 3D-Printed Particle Shapes
Authors: Amini Negin , Tuohey Joshua , Long John , Zhang Jun , Morton David , Daniels Karen , Fazelpour Farnaz , Hapgood Karen
Published: March 2021

Stress visualization within 3-dimensional particles undergoing dynamic
processes can greatly advance our understanding of complex particle
behaviors. Traditional photoelastic stress visualization methods suffer
inherent limitations from lack of available technology for complex
particle production. Recently, 3D-printing has created new possibilities
for enhancing the scope of stress analysis within physically
representative granules. Here, we investigate opportunities offered by
3D-printing a granular material with photoelastic properties. We report
the results of X-ray computed tomography and 3D-printing, combined with
traditional photoelastic analysis, to visualize strain exhibited within
simple discs to reproduced coffee beans. We find that the choice of
print layer orientation with respect to the force load affects the
optical properties of the discs, without a significant difference in
their mechanical properties. Furthermore, we present a first,
semi-quantified, measurement of stresses within 3D-printed particles of
complex shape. The promising data shows potential for applying this
method to complex assemblies of 3-dimensional particles.

Published: March 2021

Aluminum Zinc co-doped Tin Oxide (AZSO) thin film was grown by sol-gel spin
coating techniques onto a glass substrate using various doping
concentrations (0, 2, 4, 6, and 8 wt%) and the effect of doping on each
sample were studied using structural analysis; X-ray Diffraction (XRD)
pattern, gravimetric method; thin film thickness and UV photo-spectrometer;
optical properties. The results of the XRD were revealed that all the peaks
have a tetragonal phase of SnO2, which were oriented at the 110, 101, and
211 planes. The film thickness was observed to vary with doping
concentration. In the visible region, all the film samples were exhibited at
average transmittance. The coefficient of absorption was gradually increased
with an increase in photon energy at a certain level with a decrease in the
absorption coefficient as the photon energy increases further. At 550-800 nm
range of wavelength, a high extinction coefficient (k) was recorded and the
refractive index curves show regular dispersion behavior. The optical
conductivity of the films followed a similar pattern, which showed that
conductivity increased to a peak at 3.60 eV. The energy bandgap of the film
samples (AZSO1 - AZSO5) is 4.095 eV, 4.103 eV, 4.087 eV, 4.114 eV, and 4.106
eV, respectively. The studies show that the properties of Al-Zn co-doped
SnO2 films can be explored for optoelectronic applications.

Moving Hands-On Mechanical Engineering Experiences Online: Course Redesigns and Student Perspectives
Authors: Johnson Jaclyn E , Barr Nancy B
Published: March 2021

Hands-on lab experiences are essential for enabling students to be successful engineers, especially those who identify as kinesthetic learners. This case study describes how a Mechanical Engineering Practice course sequence was redesigned during the COVID-19 emergency transition to remote learning and examines how students responded to these changes. The remote course included videos of Graduate Teaching Assistants conducting data acquisition phases of the practice session to replace hands-on experiments. To understand student perspectives and performance, researchers reviewed approximately 400 reflective essays from Spring 2020, and compared assignment submissions between Fall 2019 and Spring 2020. Results suggest that some students perceived the loss of hands-on activities as detrimental to their learning and it was not comparable to face-to-face counterparts. Furthermore, students felt forced to develop self-directed learning skills. However, in contrast to student comments in reflective essays, comparisons of assignment submissions suggested that students in Spring 2020 did not receive lower grades or have a reduced demonstration of conceptual knowledge obtained in the course.

Authors: Riley Elizabeth , Capps Natalie , Ward Nicole , McCormack Leslie , Staley Judy
Published: March 2021

This study explores the effect of rapidly transitioning an in-person pre-licensure nursing specialty course to remote instruction during the COVID-19 pandemic. The redesign included the following learning technologies: live and recorded whiteboard lectures with Socratic-style questioning, electronic audience response systems, remote simulations, and virtual unfolding case studies to replace didactic and clinical learning experiences. Quantitative results indicate that learning quality was sustained, with no significant difference in students’ course performance or satisfaction. These specific technologies can be utilized in any discipline-specific course during emergency remote instruction to promote essential student-to-student and faculty-to-student interactivity.
Teachers’ Engagement in and Coping with Emergency Remote Instruction During COVID-19-Induced School Closures: A Multinational Contextual Perspective
Authors: Jelińska Magdalena , Paradowski Michał B.
Published: March 2021

The COVID-19 pandemic required educators and learners to shift to emergency remote instruction with little time for preparation. To understand how teachers managed the transition, we surveyed nearly 1,500 teachers from 118 countries from April to September 2020. Using cluster analysis, we detect two readily distinguishable groups of instructors: a group who was more engaged with remote instruction and had better coping in terms of online teaching challenges, and a group who had lower levels of both engagement and coping. We compare the two groups in terms of their sociodemographic characteristics, and also assess the relationship between each sociodemographic marker and teachers’ engagement and coping. Overall, our results suggest that teachers were most engaged and coped best with the transition when they had prior experience with remote instruction, taught in the higher education sector, and taught using real-time synchronous modalities. We also find non-trivial results regarding teachers’ gender, years of teaching experience, and their country’s level of economic development, and observe no relationship between teachers’ age and engagement or coping. The detection of the contextual effects underscores the importance of large multisite research.
Probe on Myth and Hero, A Case Study of Harry Potter: Asserting Harry Potter as a Modern Mythical Hero
Authors: Suresh Devu M
Published: March 2021

A Hero is the one who stands unique as his own, based on the presumption that, he is someone who has given his or her life to something bigger than oneself. Throughout this research paper, there have been undertaken many references and probes to the realm of ‘Hero’, obviously that of ‘Mythical Hero’, as the ideology concerning hero dates back it’s root in ancient myths and legends all over the world. Myriads of attempts have been made to the ‘Hero Myth Cycle’ proposed by Campbell, to assert the novel conception, concerning the well renowned fictional character, Harry Potter as a ‘Modern Mythical Hero’.

Published: March 2021

This contribution evaluated aspects, such as the frequency of reading, formats, and reading preferences, of secondary school students from Poland, Chile, and Portugal. For this, we started with the data obtained from a questionnaire on reading interests and frequencies, answered by 491 schoolchildren from the referred countries (175 Poles, 178 Chileans, and 138 Portuguese), on which a contrastive analysis was carried out with the aim of observing whether the strategies for promoting and consolidating reading habits should follow similar or divergent guidelines in each of the contexts. The comparison of the results indicates low reading frequencies are common to all the countries of the study, highlighting the lack of interest in reading periodicals (newspapers and magazines) and comics, although in leisure time (particularly on holidays) respondents show a greater interest in reading. Their preferences are oriented toward the adventure genre, which is followed by books on romantic themes, science fiction, mystery, terror, and humor. As for specific works and authors, we found a very heterogeneous and diverse panorama for each country. They show, in general terms, a penchant for paper in relation to reading support (e-books, in particular, are not particularly appreciated); however, a large contingent of schoolchildren are indifferent to the format. Digital reading is largely dominant in social networks. The analysis of the results reveals an important confluence in the three contexts analyzed, pointing in general to a low frequency and motivation toward reading, which is why common strategies are proposed to enhance the reading habits of Polish, Chilean, and Portuguese schoolchildren.
La competencia lectora. Una aproximación teórica y práctica para su evaluación en el aula
Authors: Díez Mediavilla Antonio , Clemente Egío Vicente
Published: March 2021

The current investigation shows, in the first place, an analysis and theoretical approach for the concept of Reading competence. This reserach works as a basis to justify that PISA (creator of this concept) doesn’t evaluate what it says to evaluate. So, we propose a new model of evaluation to assess the level of Reading comprehension, getting closer to the concept of Reading competence than Pisa has traditionally done. This research has been carried out with the participation of up to 7 classes of 4ºESO, the realization of two tests- the before mentioned one and a second one corresponding to an excerpt of a PISA test- and the later analysis and statistical comparison between them to find differences (if any) that confirm our statements and theoretical principles. For this purpose, test T has been used for related samples. The statistical analysis let us check that the new Reading approach proposed in the new model of evaluation, through which we intend to approach the concept of Reading competence, hadas a main consequence a better performance of the students in the realization of this test; in comparison with the PISA excerpt that was used. This better efficiency in the carrying out, by the students participating, of the new test, include many investigative implications towards the understanding of different concepts related to Reading that, in many occasions, are easily confused, as well as implications of a practical nature, providing many orientations towards educational interventions in the Reading skill area.
How does CLIL affect the acquisition of reading comprehension in the mother tongue? A comparative study in secondary education
Authors: Nieto Esther
Published: March 2021

In the last two decades, CLIL (content and language integrated learning) programmes, in which school subjects such as history, geography or mathematics are taught by means of an additional language, have rapidly spread over all the world, since CLIL has been deemed to be an innovative and effective approach for second language learning. Therefore, research on CLIL has precisely focused on the acquisition of the L2, while other aspects, such as the assimilation of the content taught by means of the second language or the impact of CLIL programmes on the mother tongue have received less attention.In this sense, this paper examines how CLIL programmes affect the development of reading comprehension in the mother tongue. To do so, the outcomes in a test of reading comprehension of CLIL (n = 1,119) and non-CLIL students (= 15,984) enrolled in the 2nd year of secondary education (13-14 years-old) were compared. The results indicated that the acquisition of literal reading comprehension and inferential reading comprehension in the mother tongue significantly benefit from CLIL, whereas no significant differences have been detected in critical reading comprehension. The reading skills most benefited by CLIL were global comprehension, lexical comprehension, understanding of space-time relationships, integration of extra-textual information, and identification of extra-textual relations.These data are explained by the critical importance of reading strategies to succeed in CLIL settings, and by the transfer of these strategies between L1 and L2 and vice versa. This hypothesis is supported by previous research on immersion programmes.

Job Satisfaction of Basic Education Teachers in Southeast Asia: Key Issues and Policy Recommendations
Authors: Oblina Anita Clapano , Linh Tran Phuoc , Phuong Ho Thanh My
Published: March 2021

This article is taken from the research study, “Job Satisfaction of Basic Education Teachers in Southeast Asia”, a collaborative endeavor among SEAMEO (Southeast Asian Ministers of Education Organization) Centers.  It presents the key issues affecting the level of job satisfaction among basic education teachers in Southeast Asia and provides policy recommendations to increase teacher job satisfaction and motivation. The study employs Herzberg’s Dual Factor Theory of Motivation: Hygiene factor and motivator factor; online survey, group discussion and forum are instruments used to gather data.  Analysis of responses has demonstrated that the sources of job dissatisfaction are found to be both hygiene factor and motivator factor. The top three sources of job dissatisfaction are (1) job security (salary, chances to be reclassified/ promoted/ transferred to better school, appreciation and rewards, benefits, and overall job security); (2) work environment (accessibility of textbooks, supplies, equipment, copy machine, and others, supervisor assisting teacher to improve instruction, working conditions e.g., lighting, ventilation, working space, dormitory, and others, working relationships among peers, and student’s behavior), and (3) job responsibility (workloads e.g., teaching, administrative, and paper works, instructional materials used in the school, teaching assignment relative to specialization, teacher’s autonomy to improve teaching, and grade level curriculum). Significantly, the results indicate that the greatest source of job dissatisfaction is hygiene factor.  Further research on key issues affecting teacher job satisfaction unexplored in this study is necessary.

Published: March 2021

Library is one of the information facilities that functions to open the knowledge. Currently there are various types of libraries ranging from conventional to digital. The Faculty of Engineering's Reading Room needs to be developed into a Digital Library to make it more effective and efficient in the delivery and search of libraries. Also a repository needs to be made so that the scientific papers are not only in print format. The diversity of devices at this time causes the Digital Library to not be able to be maximally accessed. So that the Digital Library can be accessed maximally, then the Digital Library needs to be developed with a responsive web-based. The method used in this research is a Prototype Method. Reasons to use the prototype method is because during the development process they could not deliver the maximum requirement needs. Wordpress.org is used as a software that builds and manages web interactions. The results of this research are the successful development of the Digital Library with a responsive web-based that makes the delivery and search of libraries effective and efficient.

Efficient quantum circuits for binary elliptic curve arithmetic: reducing $T$-gate complexity
Authors: Amento Brittanney , Rotteler Martin , Steinwalds Rainer
Published: March 2021

Elliptic curves over finite fields ${\mathbb F}_{2^n}$ play a prominent role in modern cryptography. Published quantum algorithms dealing with such curves build on a short Weierstrass form in combination with affine or projective coordinates. In this paper we show that changing the curve representation allows a substantial reduction in the number of $T$-gates needed to implement the curve arithmetic. As a tool, we present a quantum circuit for computing multiplicative inverses in $\mathbb F_{2^n}$ in depth $\bigO(n\log_2 n)$ using a polynomial basis representation, which may be of independent interest.
Gate-efficient discrete simulations of continuous-time quantum query algorithms
Authors: Berry Dominic W. , Cleve Richard , Gharibian Sevag
Published: March 2021

We show how to efficiently simulate continuous-time quantum query algorithms that run in time T in a manner that preserves the query complexity (within a polylogarithmic factor) while also incurring a small overhead cost in the total number of gates between queries. By small overhead, we mean T within a factor that is polylogarithmic in terms of T and a cost measure that reflects the cost of computing the driving Hamiltonian. This permits any continuous-time quantum algorithm based on an efficiently computable driving Hamiltonian to be converted into a gate-efficient algorithm with similar running time.
An improved query for the hidden subbroup problem
Authors: Shakeel Asif
Published: March 2021

The Hidden Subgroup Problem (HSP) is at the forefront of problems in quantum algorithms. In this paper, we introduce a new query, the \textit{character} query, generalizing the well-known phase kickback trick that was first used successfully to efficiently solve Deutsch's problem. An equal superposition query with $\vert 0 \rangle$ in the response register is typically used in the ``standard method" of single-query algorithms for the HSP. The proposed character query improves over this query by maximizing the success probability of subgroup identification under a uniform prior, for the HSP in which the oracle functions take values in a finite abelian group. We apply our results to the case when the subgroups are drawn from a set of conjugate subgroups and obtain a success probability greater than that found by Moore and Russell.
Unentangled Vitrimer Melts: Interplay between Chain Relaxation and Cross-link Exchange Controls Linear Rheology
Authors: RICARTE RALM , Shanbhag Sachin
Published: March 2021

Using this theoretical approach, we explore the influence of molecular structure and temperature on vitrimer linear viscoelasticity. We observe that vitrimers with uniform and random cross-link distributions exhibit larger viscosities and relaxation times than gradient and blocky types. Polydimethylsiloxane vitrimer (which has a flexible backbone) shows an Arrhenius temperature dependence for viscosity, while polystyrene vitrimers (which has rigid backbones) are only Arrhenius at high temperatures. During stress relaxation, the short time dynamics represent monomer friction, while the long time dynamics encompass a combination of network strand relaxation and cross-link exchange. Because of the different temperature dependences of the processes, time-temperature superposition fails. We also show that the effective rheological activation energy can be estimated a priori using only the cross-link exchange activation energy and the backbone Williams-Landel-Ferry parameters.

Authors: Sun Qiang , Mateos Luis M. , Robles Roberto , Lorente Nicolas , Ruffieux Pascal , Bottari Giovanni , Torres Tomás , Fasel Roman
Published: March 2021

Porphyrin nanotapes (Por NTs) have attracted vast interest as potential molecular wires thanks to their exceptional electronic properties. Recently, Por NTs have been synthesized by solution-based methods, demonstrating high versatility and great potential for technological applications. However, their synthesis is tedious and their characterization limited by low solubility and stability. Here, we report the first example of meso-meso triply-fused Por NTs, which are prepared from a readily available Por precursor through a two-step synthesis on Au(111). The structural and electronic properties of individual Por NTs are addressed, both on Au(111) and on a thin insulating NaCl layer, by high-resolution scanning probe microscopy/spectroscopy complemented by density functional theory calculations.
Photoredox Catalysis Using Heterogenized Iridium Complexes
Authors: Materna Kelly L. , Hammarström Leif
Published: March 2021

Heterogenized photoredox catalysts provide a path to generating chemicals in an environmentally friendly way, with facile reuse of catalysts in batch or continuous processes. In this study, heterogenized iridium complexes as photoredox catalysts were assembled via covalent attachment to three metal oxide surfaces (ITO, ZrO2, Al2O3) either in the form of thin films or nanopowders and tested as photoredox catalysts for reductive dehalogenation of bromoacetophenone to acetophenone. All catalysts produced acetophenone with high conversions and yields. The fastest reactions were complete in fifteen minutes under mild conditions using Al2O3 surfaces, which provided the most robust and reusable supports. The catalytic performance was compared on both nanopowder and thin film supports, showing that both constructs could be used for photoredox catalysis. The nanopowder-based catalysts resulted in faster and more efficient catalysis, while the thin film-immobilized catalysts were more robust and easily reused. Importantly, the thin film constructs show promise for future photoelectrochemical and electrochemical photoredox setups. Finally, all catalysts could be reused 2-3 times, performing at least 1000 turnovers with Al2O3 supports, highlighting that heterogenized catalysts can perform photoredox catalysis in an environmentally friendly fashion.
pH-Independent Heat Capacity Changes during Phosphorolysis Catalyzed by the Pyrimidine Nucleoside Phosphorylase from Geobacillus thermoglucosidasius

Published: March 2021

Enzyme-catalyzed reactions sometimes display curvature in their Eyring plots in the absence of denaturation, indicative of a change in activation heat capacity. However, pH and (de)protonation effects on this phenomenon have remained unexplored. Herein, we report a kinetic characterization of the thermophilic pyrimidine nucleoside phosphorylase from Geobacillus thermoglucosidasius across a two-dimensional working space covering 35 °C and 3 pH units with two substrates displaying different pKa values. Our analysis revealed the presence of a measurable activation heat capacity change in this reaction system, which showed no significant dependence on medium pH or substrate charge. Our results further describe the remarkable effects of a single halide substitution which has a minor influence on the heat capacity change but conveys a significant kinetic effect by lowering the activation enthalpy, causing a >10-fold rate increase. Collectively, our results present an important piece in the understanding of enzymatic systems across multidimensional working spaces where the choice of reaction condition can affect rate, affinity and thermodynamic phenomena independently of one another.

Social Interaction and Social Media At Airport Departure Gates
Authors:   1University of Miami / Miller School of Medicine. 2Fielding Graduate University.
Published: March 2021

An observational study was conducted at airline departure gates in several U.S. and European countries. Thirty-second observations were randomly made of 1360 different individuals ranging in age from infants to the elderly, although 79% of the travelers were adults. Most of the individuals were traveling with someone, except for adults who were more often traveling alone (58% vs. 42% time). Of the different types of social interaction and social media observed, cell phone texting/scrolling was significantly more frequently observed (at 53% time) than cell phone talking (13 % time), face-to-face interaction (13% time), on computer (7%) and touching (4%) which was the least frequently observed behavior. Significantly more cell phone texting/scrolling time occurred when adults were traveling alone (58% time). These data suggest that airline travelers are spending significantly more airport departure gate time on social media (specifically cell phone texting/scrolling) than face-to-face interaction or touching. Unfortunately, the observations that were made by professors and students were from too great a distance (10 feet away) in order to be unobtrusive but unable to code the precise type of cell phone texting/scrolling that was occurring.
Ameliorating Accuracy of a Map Navigation When Dealing with Different Altitude Traffics that Share Exact Geolocation
Authors: Patanasakpinyo Thitivatr
Published: March 2021

Many users use a location-based application on a portable device to be a navigator when driving. However, there exists an incident that two roads are located on the same geolocation, i.e., same values of latitude and longitude but different altitude, for very long distance where one road is located on the ground level and another one is elevated. This incident mostly confuses a location-based application to precisely retrieve the actual road that a vehicle is currently on and, consequently, causes the application to either navigate incorrectly or suggest a route that is a detour. Calling an altitude from a GPS sensor might be a possible solution but it came with problems of accuracy, especially for mid-grade GPS sensors that equipped with most smartphone in today’s market. We proposed a concept of implementing a classification model that can classify whether a vehicle is on a ground road or an elevated road regardless of geolocation data. We trained and validated two models using a dataset that we had collected from actual driving on two roads in Thailand that fell under this condition. A data instance that we collected contained measurements related to driving or driving environment such as a real-time speed at any certain interval of time. We reported validation results of both models as well as other important statistics.
Boerhaave syndrome, a rare oesophageal rupture: a case report
Authors: Horrocks Rebecca
Published: March 2021

 Boerhaave syndrome is a disorder mainly unknown among ambulance staff. However, the high mortality and morbidity rates associated with this rare disorder, and the fact that other conditions present with similar symptoms, suggest that this is one
disorder to add to the differential diagnosis list. This case study describes a 17-year-old male complaining of left-sided ‘pressure’-type chest pain and persistent vomiting who on examination was found to have subcutaneous emphysema present. Deceived by a differential diagnosis,
the patient was transferred under the belief that he had suffered a spontaneous pneumothorax as he was tall, young and thin. This case report reviews the literature surrounding Boerhaave syndrome and how it can present.

Published: March 2021

Multi-storey building must be equipped with a reliable building fire extinguishing system. The existing fire extinguishing system design is not equipped with a backup pump and a jockey pump. Based on The DKI Jakarta Governor Regulation No. 92/2014 and the Indonesian National Standard, to solve this problem, a building fire pump system is designed with a combination of the jockey pump, main pump and backup pump that connected in an integrated parallel arrangement. This design allows the backup pump to automatically run due to a pressure drop in the system pipe if the main pump fails or unable to build up pressure. When a fire occurs and a lot of hydrants are used, the backup pump will automatically run to help the main pump with a signal triggered by the pressure switch.
