Perioperative management of a patient with multiple drug hypersensitivity syndrome: Anesthesia perspective
Authors: Sany Salina , Leow Voon Meng , Abdul Ghaffar Zainab , Lim Jo Anne , Chong Soon Eu 
Published: December 2020

Patients with multiple drug hypersensitivity often pose significant challenge during surgery because of the greater risk of developing anaphylactic shock that could be fatal. The use of novel pharmaceutical agents such as anesthetic drugs and medical devices made from a wide range of chemicals and materials with unknown antigenicity potentially predisposes this subset of patients to hypersensitivity reactions in the perioperative period.
The authors encountered a 20-year-old patient with a history of multiple drug hypersensitivities, who had been diagnosed with a huge ovarian tumor. She underwent surgery successfully but faced a rather difficult recovery. Herein, we discuss the management of unexpected perioperative outcomes with the support of literature review. This article also highlights the use of drug provocation tests and the necessary precautions to be taken in the absence of standardized preoperative guidelines for patients with multiple drug hypersensitivity syndrome undergoing major surgical procedures.

Authors: EL AMRI Ayoub , EL ABDI Fahd , ELHASNAOUI Mohammed Amine , EL KOUNDI Abdelghafour 
Published: December 2020

Neurofibromatosis type 1 is a rare neurocutaneous condition that can have widespread and deleterious effects on various organ systems, including the spine with implications for the choice of anesthetic technique.
We report the case of a parturient, who was received in the emergency room of the maternity ward of our hospital during the active phase of labor, without neuraxial imaging, in whom a cesarean section was indicated and performed under general anesthesia.
Anesthesia for the parturient with neurofibromatosis is still not well documented, its management needs to be multidisciplinary, with a careful pre-conception planning.
Key words: Neurofibromatosis, imaging, neuraxial anesthesia, pregnancy.

ANALYSIS OF APPLICATION OF CONTEMPORARY NIGHT VISION GOGGLES ON THE BASIS OF ELECTRONIC-OPTICAL CONVERTER BY THE HELICOPTER CREWS. PROSPECTIVE HELICOPTER OPTOELECTRONIC SYSTEMS OF AERIAL RECONNAISSANCE/SURVEILLANCE

Published: December 2020

The paper studies the matters of using of night vision goggles by the helicopter crews of the State Aviation of Ukraine. The analysis of the perspective systems that can replace night vision goggles based on electronic-optical converter and provide round-the-clock and all-weather flights, landing of the helicopter on unprepared and unlit areas in poor visibility was treated.
Currently, the practice of using combat and transport helicopters involves their wider use in the night-time conditions (air warfare, delivery of goods, search-and-rescue operations). Due to low light levels, until recently, most night-time target acquisition tasks have been related with the necessities of providing the artificial target illumination, but in certain instances such illumination deteriorates visibility through an lighttight, phosphorescent atmospheric shells or it just can‟t be carried out.
The need for a large number of channels included in the optoelectronic system, caused by the variety of tasks that are solved by it, as well as the imperfection of each individual channel. This forces them to be combined to improve the efficiency of the optoelectronic systems themselves, so that the disadvantages of one channel are offset by the advantages of another.
In fact, it is only possible way to ensure the fulfilment of combat task by combining channels operating in different spectral bands in one scheme and by combining detection devices.
It can be stated that, despite the undisputed advantages of optoelectronic systems as compared to night-vision goggles, in case of the selecting for installing on a helicopter of optoelectronic systems, it should take into account the much higher cost of optoelectronic systems compared with night-vision goggles. Therefore, the rationale for installing optoelectronic systems must be determined based on the scope of the executing tasks, which are to be conducted by a specific helicopter.
RECOMMENDATIONS GENERALIZATION FOR IMPROVING THE METHODOLOGY OF SUBSTANTIATION OF REQUIREMENTS FOR THE VALUES OF QUANTITATIVE INDICATORS OF ARMAMENT AND MILITARY EQUIPMENT UNIFICATION
Authors: Shaporenko V. , Dmytriiev V. 
Published: December 2020

Establishing the optimal values of quantitative indicators of the level of unification for armaments and military equipment (AME) samples during the elaborating of technical development requirements (TDR) for research and development work (R&D) on their creation (modernization) is still an urgent task, as they (values) directly affect technical and economical evaluation of AME samples.
It is stipulated in the normative documents that quantitative indicators of the unification level of the sample are determined by the factors of applicability and repeatability of the standard sizes of assembly units and parts of the sample. In addition, the formulas for their calculation are also specified in these documents. It makes possible to assess only the actually achieved level of unification, while the question of a methodological approach to establishing the values of indicators in the requirements of the TDR remains open.
In previous studies, the author has consistently developed recommendations for establishing optimal values of quantitative indicators of the level of unification for AME samples. This paper summarizes the recommendations on the method of substantiation of requirements for the values of quantitative indicators of AME unification.
The author proposes to replace the factor of repeatability with a relative factor of repeatability, which allows determining the indicators in single units (in percent) and, accordingly, applying a single method of their establishment.
The proposed general methodological approach to substantiation of quantitative indicators of the unification level consists of four stages:

determination of the basic level of quantitative indicators of the unification level;
determination of the list of factors that affect the level of unification, differentiation of factors by the nature of the impact and determining the rating of their significance;
determination of coefficients of factors that influence the unification level;
calculation of quantitative indicators of the unification

The paper provides a clear algorithm and recommendations for sequential execution of stages.
Taking into account the positive results of previous studies, generalized recommendations for improving the methodology of substantiation of requirements for the values of quantitative indicators of unification were developed. These recommendations can be practically applied in the process of setting requirements in the TDR for R&D on the development of AME samples.
A Volume-limited Sample of Ultracool Dwarfs. I. Construction, Space Density, and a Gap in the L/T Transition
Authors: Best William M. J. , Liu Michael C. , Magnier Eugene A. , Dupuy Trent J. 
Published: December 2020

Abstract
We present a new volume-limited sample of L0–T8 dwarfs out to 25 pc defined entirely by parallaxes, using our recent measurements from UKIRT/WFCAM along with Gaia DR2 and literature parallaxes. With 369 members, our sample is the largest parallax-defined volume-limited sample of L and T dwarfs to date, yielding the most precise space densities for such objects. We find the local L0–T8 dwarf population includes

young objects (≲200 Myr) and

subdwarfs, as expected from recent studies favoring representative ages ≲4 Gyr for the ultracool field population. This is also the first volume-limited sample to comprehensively map the transition from L to T dwarfs (spectral types ≈L8–T4). After removing binaries, we identify a previously unrecognized, statistically significant (>4.4σ) gap ≈0.5 mag wide in

colors in the L/T transition, i.e., a lack of such objects in our volume-limited sample, implying a rapid phase of atmospheric evolution. In contrast, the most successful models of the L/T transition to date—the “hybrid” models of Saumon & Marley—predict a pileup of objects at the same colors where we find a deficit, demonstrating the challenge of modeling the atmospheres of cooling brown dwarfs. Our sample illustrates the insights to come from even larger parallax-selected samples from the upcoming Legacy Survey of Space and Time by the Vera Rubin Obsevatory.

Abstract
Coronal waves exist ubiquitously in the solar atmosphere. They are important not only because of their rich physics but also because they are essential candidates for triggering remote magnetic eruptions. However, the latter mechanism has never been directly confirmed. By revisiting the successive eruptions on 2012 March 7, fast-mode shocks are identified to account for the X5.4 flare-related Extreme UltraViolet wave with a velocity of 550 km s−1, and appeared faster than 2060 ± 270 km s−1 at the front of the corresponding coronal mass ejection in the slow-rising phase. They not only propagated much faster than the local Alfvén speed of about 260 km s−1, but also were simultaneously accompanied by a type II radio burst, i.e., a typical feature of a shock wave. The observations show that the shock wave disturbs the coronal loops C1 connecting active regions (ARs) 11429 and 11430, which neighbor a null point region. Following a 40 minute oscillation, an external magnetic reconnection (EMR) occurred in the null point region. About 10 minutes later, a large-scale magnetic flux rope overlaid by C1 became unstable and erupted quickly. It is thought that the fast-mode shock triggered EMR in the null point region and caused the subsequent eruptions. This scenario is directly observed for the first time, and provides new hints for understanding the physics of solar activities and eruptions.
[N ii] Fine-structure Emission at 122 and 205 μm in a Galaxy at z = 2.6: A Globally Dense Star-forming Interstellar Medium

Published: December 2020

Abstract
We present new observations with the Atacama Large Millimeter/submillimeter Array of the 122 and 205 μm fine-structure line emission of singly ionized nitrogen in a strongly lensed starburst galaxy at z = 2.6. The 122/205 μm [N ii] line ratio is sensitive to electron density,

, in the ionized interstellar medium, and we use this to measure n
e ≈ 300 cm−3, averaged across the galaxy. This is over an order of magnitude higher than the Milky Way average, comparable to localized Galactic star-forming regions. Combined with observations of the atomic carbon (C i) and carbon monoxide (CO J = 4–3) in the same system, we reveal the conditions in this intensely star-forming system. The majority of the molecular interstellar medium has been driven to high density, and the resultant conflagration of star formation produces a correspondingly dense ionized phase, presumably colocated with myriad H ii regions that litter the gas-rich disk.
Measuring Solar Differential Rotation with an Iterative Phase Correlation Method
Authors: Hrazdíra Zdeněk , Druckmüller Miloslav , Habbal Shadia 
Published: December 2020

Abstract
A reliable inference of the differential rotation rate of the solar photosphere is essential for models of the solar interior. The work presented here is based on a novel iterative phase correlation technique, which relies on the measurement of the local shift, at the central meridian, between two images separated by a given time interval. Consequently, it does not require any specific reference features, such as sunspots or supergranules, nor extended observations spanning several months. The reliability of the method is demonstrated by applying it to high spatial and temporal resolution continuum images of the solar photosphere, at 6173 Å, acquired by the Solar Dynamics Observatory Helioseismic and Magnetic Imager over one complete Carrington rotation. The data selected covers the time period of 2020 January 1 to February 2. The method was applied to one day, and to the full time interval. The differential rotation rate derived using this feature-independent technique yields values that fall in the middle of the range of those published to date. Most importantly, the method is suited for the production of detailed rotation maps of the solar photosphere. It also enables the visual and quantitative identification of the north–south asymmetry in the solar differential rotation rate, when present.
Intensity Distribution in the Heads of Comets
Authors: Haser L. , Oset Shawn , Bodewits D. 
Published: December 2020

Abstract
In optical wavelengths, the light emitted by comets consists of sunlight, reflected by dust, and the emission features of atoms and molecules. In his paper from 1957, L. Haser develops the mathematical framework to describe the density distribution of cometary comas. When comet scientists refer to the Haser model , they mostly point to the density distribution of parent and fragment molecules in the coma. However, in his paper, Haser (1957) presented the analytic solution over the line of sight (column density) and considers two particular observation configurations of a nonhomogeneous coma. This translation of the paper, originally in French, stays as close to the source as possible, including using the original figures. Minor typesetting corrections were introduced and are annotated in the text. The Haser model is foundational in cometary atmosphere science, but Haser’s paper was not widely read due to language barriers and a lack of digital availability. This translation is presented in an effort to make Haser’s work accessible to the wider community. We would like to thank Drs Emmanuel Jehin (Univ. Liège) and Kumar Venkataramani (Auburn Univ.) for critically reading this translation.

Published: December 2020

As demandas de integração entre áreas de conhecimento e de vinculação de conteúdos escolares com elementos vivenciais dos sujeitos podem ser compreendidas no escopo de abordagem de temas contemporâneos na Educação Básica. Essa perspectiva pode agregar problematização de relações entre Ciência, Tecnologia, Sociedade e Ambiente (CTSA), o posicionamento e a proposição de alternativas, direcionados a questões controversas. Nessa vertente educativa, apresentam-se, neste relato de experiência, análises concernentes ao desenvolvimento de proposta educacional no âmbito do Programa de Residência Pedagógica de Física, com alunos do terceiro ano de uma instituição pública de Curitiba, Paraná, entre os meses de fevereiro e setembro de 2019. Essas ações foram empreendidas considerando pressupostos de abordagem de relações entre CTSA e engajamento, com tema vinculado à Produção, Distribuição e Uso de Energia Elétrica. Em referência a esse processo, objetiva-se apontar desafios estruturais, curriculares e metodológicos. Entre as atividades educacionais desenvolvidas, destacam-se processos de leitura, discussão, experimentação e elaboração de maquetes. As análises incidiram sobre relatórios elaborados pelos residentes, materiais produzidos pelos alunos da Educação Básica (atividades escritas, entregues em papel e no Google Classroom; maquetes) e questionário. Os materiais escritos foram analisados considerando elementos de Análise de Conteúdo. No processo de análise de dados, foram destacados aspectos de engajamento dos estudantes e correlações com desafios estruturais, curriculares e metodológicos. Evidenciou-se engajamento dos estudantes nas atividades, com reconhecimento, problematização e proposição de alternativas a situações problemáticas contemporâneas. Contudo, identificaram-se dificuldades concernentes à participação de estudantes e utilização de elementos de matemática. Em termos de desafios, houve necessidade de adaptações e articulações, considerando características das instituições e sujeitos envolvidos; estes compreenderam vertente estrutural, organização curricular e abordagem metodológica, concernentes à ruptura com aspectos de ensino tradicional. Salienta-se que o desenvolvimento da referida proposta viabilizou aos residentes a articulação entre teoria e prática, com ação e reflexão direcionadas à própria prática educacional
Demonstração com tecnologia: um estudo sobre o número de diagonais de um prisma
Authors: Pavanelo Elisangela 
Published: December 2020

Este trabalho apresenta uma investigação sobre a maneira pela qual o professor pode compreender uma atividade relativa ao número de diagonais de um prisma, através do uso de tecnologia digital. Inicialmente, apresentam-se considerações teóricas em relação à ideia de demonstração a partir de um trabalho com tecnologias digitais. Entendemos, nesse trabalho, a demonstração em matemática conforme discutido em Mod (2016) e Bicudo, I. (2002), os quais destacam que a riqueza de uma demonstração pode não residir somente na prova da tese nele contida, mas na Matemática que é desenvolvida pelas tentativas de demonstração, além de observar que o caminho para se chegar até ela é tão importante quanto o resultado final. O uso do computador pode levar a descoberta de novas maneiras, tanto para professores e alunos, quanto para os matemáticos, de se desenvolver uma demonstração matemática, mas isso não exime a presença da criatividade e intuição. Trata-se de um trabalho de caráter qualitativo, desenvolvido a partir de um estudo de caso com professores de Matemática, utilizando-se a fenomenologia como metodologia de análise. Propõe-se a análise a partir das transcrições obtidas durante encontros com professores de Matemática de uma escola estadual de Aparecida – SP. Procura-se destacar a contribuição que o software GeoGebra oferece ao processo de demonstração em geometria. A utilização do computador possibilitou a representação de um objeto geométrico, utilizado na avaliação de ideias e hipóteses, as quais permitiram a criação de um contexto abstrato e simbólico. Foi identificado que, no caso discutido, não ocorreu a transposição das hipóteses vistas, ou percebidas, para o mundo simbólico matemático.
