Saúde mitocondrial – implicações de estilo de vida e envelhecimento para a CoViD-19: uma resenha do artigo de Nunn et al.
Authors: JPE REF 
Published: February 2021

Introdução: Como parte da Edição Especial de 2020 I, a Revista de Educação Física / Journal of Physical Education (REF/JPE) está trazendo aspectos científicos da prática de atividade física relacionados à pandemia de CoViD-19.
Objetivo: Apresentar e indicar aos leitores da REF/JPE, a leitura da revisão integrativa de Nunn et al., publicado em um periódico internacional, que analisou a literatura a respeito da relação da saúde mitocondrial nos contextos de estilo de vida e envelhecimento e potenciais associações com desfechos de CoViD-19.
Conclusão: Após a profunda e abrangente discussão sobre o que a literatura apresenta sobre o tema abordado, os autores apontaram que a ideia de que a saúde mitocondrial, induzida por um estilo de vida saudável, pode ser um fator fundamental na resistência ao vírus SARS-CoV2. Além disso, apontaram que, para pessoas que não estejam em ótima saúde, tratamentos que apoiem a função mitocondrial podem ser essenciais para a recuperação a longo prazo.
Letter to the Editor: Strawberries: Facts, Truth, Misinformation, Publication Bias and the Importance of Negative Results.
Authors: Dennis Robert 
Published: February 2021

We commonly make the assumption that information provided in instructions and/or publications is correct and based on proven and unbiased knowledge. In a recent study about strawberry seed germination, which will be reported concurrently with this letter, seed supplier’s instructions (based on accepted wisdom among growers) were actually tested, and the results of that part of the study brought to mind the insidious nature of publication bias. This testing was done because the seed planting in question was a crucial component of a scientific study I recently completed on the effects of electromagnetic fields on seed germination in which more than 7,000 seeds were planted, carefully and individually, and their germination rates were studied closely.
Briefly, the recent study to which I will make reference describes the interaction between three different treatments prior to planting the seeds: pre-freezing, pre-soaking, and the application of PEMF. It is widely held that the first two, especially pre-freezing, is essential for strawberry seed germination. These procedures are also often reported in the methods section as a side note in scientific reports, so I took them as a given. Our goal was to determine the extent to which the application of PEMF interacted with either or both of the widely accepted pre-treatments. But when the data came in, I did not see evidence of any positive effects on germination resulting from either pre-treatment when studied separately or in combination. In fact, both pre-treatments appeared to have a slight negative effect on the germination rate, and neither under any circumstances interacted with PEMF treatment in a positive way at any level of practical importance. These negative results will be submitted for publication in JoSaM, in keeping with our policy to fight against publication bias.
Quality Metric for Spitzer–Braginskii and Grad 8 Moment Heat Flux Closures
Authors: Scudder J. D. 
Published: February 2021

Abstract
Quality metrics for Spitzer–Härm and Grad closures are presented based on the percentage of the heat flux moment supported only by nonnegative, physical, phase space densities

underlying the closure. The Spitzer and Grad qualities exceed 95% for the perturbative regimes where Spitzer’s formulation is analytically known to be convergent. Beyond this regime both heat flux qualities fall about 30% per decade increase of ϵ > 0.01. In the solar corona the first decade’s decrease in quality straddles the radius of the coronal temperature maximum and spans the initial acceleration of the solar wind. By the end of the second decade of increase of ϵ the observer is between 5 and 10R
⊙, already in conditions comparable to those at 1 au with ≃60% degradation of quality. These strong radial decays of closure quality show that integrating the fluid equations using such closures must represent a very poor assay of the role and effects of ∇ · q had the heat flux been described throughout with a uniformly high quality closure procedure. For small ϵ,

occurs for cosine of pitch angle μ < 0 opposed to q at speeds above 2 thermal speeds and are omnipresent (but ignorable) for truly perturbative closures. Above a computed threshold in ϵ unphysical

occurs for speeds below 2 thermal speeds with μ > 0. The present work graphically shows

regimes becoming increasingly pervasive as ϵ increases, first crossing ≃4 thermal speeds at μ < 0 and then representing ever larger unphysical incursions within the needed velocity sphere required to accurately determine the heat flux.
A Catalog of High-velocity C iv Mini-broad Absorption Lines in the VLT-UVES and Keck-HIRES Archives
Authors: Chen Chen , Hamann Fred , Ma Bo , Murphy Michael 
Published: February 2021

Abstract
We present a catalog of high-velocity C iv
λ1548,1551 mini-broad absorption lines (mini-BALs) in the archives of the Very Large Telescope-UV Visual Echelle Spectrograph and Keck-High Resolution Echelle Spectrometer. We identify C iv mini-BALs based on smooth rounded BAL-like profiles with velocity blueshifts <−4000 km s−1 and widths in the range 70 ≲ FWHM(1548) ≲ 2000 km s−1. We find 105 mini-BALs in 44 quasars from a total sample of 638 quasars. The fraction of quasars with at least one mini-BAL meeting our criteria is roughly ∼9% after correcting for incomplete velocity coverage. All of the systems are highly ionized based on the strong presence of N v and O vi and/or the absence of Si ii and C ii when within the wavelength coverage. Two of the mini-BAL systems in our catalog, plus three others at smaller velocity shifts, have P v λ1118,1128 absorption indicating highly saturated C iv absorption and total hydrogen column densities ≳1022 cm−2. Most of the mini-BALs are confirmed to have optical depths ≳1 with partial covering of the quasar continuum source. The covering fractions are as small as 0.06 in C iv and 0.03 in Si iv, corresponding to outflow absorbing structures <0.002 pc across. When multiple lines are measured, the lines of less abundant ions tend to have narrower profiles and smaller covering fractions indicative of inhomogeneous absorbers where higher column densities occur in smaller clumps. This picture might extend to BAL outflows if the broader and generally deeper BALs form in either the largest clumps or collections of many mini-BAL-like clumps that blend together in observed quasar spectra.
Understanding the Puzzling Acceleration of Jets of Active Galactic Nuclei
Authors: Xu Qian , Gong Bi-Ping , Liu Meng-Xu , Lu Ru-Sen , Yan Xi , Dong Shi-Yin 
Published: February 2021

Abstract
As relativistic plasma launches from a compact object at the center of a galaxy, the corresponding outflow should slow down with the increase of separation from the core due to energy dissipation along the path. However, some long-baseline observations of active galactic nucleus (AGN) jets show that the velocity of jets increases rather than decreases at a larger and larger separation from the core. The mechanism of such an acceleration of astrophysical jets has not been well understood so far, although much progress has been achieved on theoretical and observational perspectives. This paper illustrates the phenomenon of jet acceleration that emerged in some AGNs by the nonballistic model in which some nonconsecutive knots are produced by a continuous outflow at different distances from the central black hole; such knots appear to rotate along different radii at the same precession cone in the case of a precessing jet. The projection of the trajectories of such knots on the plane of the sky leads us to expect that jet components further from the core move at larger apparent velocities. The investigation provides a very simple scenario to the puzzling phenomena of astrophysical jets.
Measuring Turbulence with Young Stars in the Orion Complex
Authors: Ha Trung , Li Yuan , Xu Siyao , Kounkel Marina , Li Hui 
Published: February 2021

Abstract
Stars form in molecular clouds in the interstellar medium (ISM) with a turbulent kinematic state. Newborn stars therefore should retain the turbulent kinematics of their natal clouds. Gaia DR2 and APOGEE-2 surveys in combination provide three-dimensional (3D) positions and 3D velocities of young stars in the Orion Molecular Cloud Complex. Using the full 6D measurements, we compute the velocity structure functions (VSFs) of the stars in six different groups within the Orion Complex. We find that the motions of stars in all diffuse groups exhibit strong characteristics of turbulence. Their first-order VSFs have a power-law exponent ranging from ∼0.2–0.5 on scales of a few to a few tens of parsecs, generally consistent with Larson’s relation. On the other hand, dense star clusters, such as the Orion Nebula Cluster (ONC), have experienced rapid dynamical relaxation, and have lost the memory of the initial turbulent kinematics. The VSFs of several individual groups and the whole Complex all show features supporting local energy injection from supernovae. The measured strength of turbulence depends on the location relative to the supernova epicenters and the formation history of the groups. Our detection of turbulence traced by young stars introduces a new method of probing the turbulent kinematics of the ISM. Unlike previous gas-based studies with only projected measurements accessible to observations, we utilize the full 6D information of stars, presenting a more complete picture of the 3D interstellar turbulence.
Peer Debriefing Versus Instructor-Led Debriefing for Nursing Simulation
Authors: Rueda-Medina Blanca , Schmidt-RíoValle Jacqueline , González-Jiménez Emilio , Fernández-Aparicio Ángel , Encarnación Aguilar-Ferrándiz María , Correa-Rodríguez María 
Published: February 2021

Background:
Debriefing is the reflective process following the simulation experience. We aimed to compare the debriefing assessment and debriefing satisfaction perceived by nursing students who underwent different debriefing methods.

Method:
An experimental study conducted on three groups (instructor-led debriefing, peer debriefing, and combined debriefing) was performed for 177 nursing students. Differences in the debriefing satisfaction were assessed using the Clinical Experience Simulation scale, the Visual Analogue scale, and the Debriefing Assessment for Simulation in Healthcare (DASH).

Results:
VAS scores for satisfaction differed significantly between the instructor-led debriefing, peer debriefing, and combined debriefing groups. In the Clinical Experience Simulation scale, the combined debriefing group was significantly higher compared with instructor-led debriefing. The total score for DASH was significantly higher in the combined debriefing group compared with instructor-led debriefing, and in instructor-led debriefing compared with peer debriefing.

Conclusion:

Combining debriefing after a simulation session improves the debriefing satisfaction and the perceived debriefing assessment among nursing students.

« Construire ou pas ? »
Authors: Venouil Alexia 
Published: February 2021

L’article s’intéresse aux discours de justification autour de la construction de prisons, produits par des acteurs politiques et administratifs, qui y sont favorables ou opposés. À partir d’entretiens, de rapports et de discours publics au Canada et en France, trois types d’arguments sont mis en évidence : humanisation des conditions de détention, sécurité et rentabilité économique. Nous montrons que ces arguments sont réversibles, justifiant aussi bien la décision de construction et de non-construction. Cet article éclaire sur la singularité de l’institution carcérale qui réside dans la difficulté de la mettre en discours, tant pour ses partisans que pour ses opposants.

Tinjauan Perspektif Iman Kristen tentang Mangadati dalam Pernikahan Masyarakat Batak Toba
Authors: Siahaan Vera Herawati , Yasin Harlin 
Published: February 2021

The Toba Batak traditions in terms of "mangadati" carry out traditional Batak Toba cultural events that adhere to the exogamy law, namely marriages outside certain ethnic groups. This is seen in the Batak Toba community where people do not take wives from the clan group themselves (namariboto), because they are called siblings; women leave their groups and move to the husband's group, and are patrilineal, with the aim of preserving the husband's clan within the male line. This article uses the method of phenomenological analysis with a biblical reflection approach. Mangadati marriage custom from the perspective of Christian faith is not a contradiction, because the custom is done with love, the value of respect and the value of brotherhood and togetherness in accordance with Matthew 22: 37-40.

Abstrak
Adat Batak Toba dari sisi “mangadati” melaksanakan acara adat kebudayaan Batak Toba yang menganut hukum eksogami, yaitu perkawinan di luar kelompok suku tertentu. Ini terlihat dalam masyarakat Batak Toba di mana orang tidak mengambil isteri dari kalangan kelompok marga sendiri (namariboto), karena disebut kakak-adik; perempuan meninggalkan kelompoknya dan pindah ke kelompok suami, dan bersifat patrilineal, dengan tujuan untuk melestarikan marga suami di dalam garis lelaki. Artikel ini menggunakan metode analisis fenomenologi dengan pendekatan refleksi biblikal. Adat pernikahan mangadati ditinjau dari perspektif iman kristen bukan suatu yang bertentangan, karena adat dilakukan dengan kasih, nilai hormat dan nilai persaudaraan serta nilai kebersamaan sesuai dengan Matius 22: 37-40.
The Effects of Task Load and Change Elements on Change Blindness
Authors: Volkamer Amanda , Sexton-Radek Kathy 
Published: February 2021

The experiment discussed in this paper looks at effects of high and low task loads on detecting change in three conditions; the Control, Change, and Inverse. We wanted to look at how detection of a change may be impacted by the kind of change occurring and the task load. Our first hypothesis predicts that the high-load task will result in more misidentification of the target element than the low-load task. Our other hypothesis predicts the Inverse condition will result in more correctly identified target elements than the Change condition. Our results did not support our first hypothesis of the task load as there were no main effects in Load in the first two datasets. Our second hypothesis was not supported and the results showed that the inverse condition was misidentified more so than the Change condition.

El presente estudio tiene como objeto analizar la regulación legal
de la gestión técnica del sistema eléctrico español. Para ello, se abordan las especificidades
de carácter técnico, económico y jurídico definidas en la normativa
comunitaria, nacional y reglamentaria. Una primera parte ofrece una panorámica
general sobre el concepto y naturaleza jurídica de la gestión técnica del sistema,
lo que nos permite clarificar el papel que juega el operador del sistema dentro de
la actividad de suministro de electricidad. Tras ello, analizamos exhaustivamente
el régimen de separación de la actividad de gestión técnica y las funciones específicas
que representa, para lo que resulta preceptivo llevar a cabo una lectura paralela
de la norma comunitaria y estatal. Por último, examinamos el marco europeo
para la mejora de una gestión técnica basada, de un lado, en un óptimo marco de
cooperación regional entre operadores del sistema y, de otro, en una adecuada
configuración de códigos de red y directrices europeos.

The purpose of the present study is to analyze the legal regulation
of the technical management of the Spanish electricity system. For it, we study the
technical, economic and legal specificities laid down in the European, national and
administrative regulation. The first part provides with a general overview of the
concept and legal nature of the technical management of the electricity system.
This helps us to clarify the role that the transmission system operator is playing
with the electricity supply activity. After that, we thoroughly analyze the regulatory
framework on unbundling and the functions of the Transmission System Operator,
so it is obligatory that we undertake a parallel reading of the Spanish and
the European regulation. Lastly, we examine the European framework for the
improvement of the technical management based on the one hand on the
cooperation at regional level and, on the other hand, on the proper elaboration of
the European Network Codes and guidelines.

Iatrogenic pericallosal artery aneurysm after endovascular procedure
Authors: Brzegowy Paweł , Ciuk Katarzyna , Łasocha Bartłomiej , Chukwu Osit , Kwinta Borys , Urbanik Andrzej , Popiela Tadeusz J. 
Published: February 2021

Iatrogenic brain aneurysms are rare and are usually a result of direct trauma to the arterial wall during various neuro­surgical or endovascular procedures. Single cases of pericallosal posttraumatic and postsurgical aneurysms were previously reported. Herein, we report the first confirmed case of iatrogenic pericallosal artery aneurysm caused by an arterial wall injury during the endovascular treatment of another aneurysm.<br />
A 50-year-old woman with ruptured anterior communicating artery aneurysm was initially treated with balloon-assisted coiling. During the procedure the tip of a microwire inserted into balloon catheter placed in the pericallosal artery caused a local injury of the inner layer of the vessel wall and vasoconstriction, without bleeding, dissection, or flow disturbances visible in digital subtraction angiography (DSA). Control examination revealed dissecting peri­callosal aneurysm. After standard dual-antiplatelet oral preparation, stent-assisted coiling of the pericallosal artery aneurysm was performed with residual contrast filling of the base of the aneurysm sac in control angiography (RROC III). After 6 months the control DSA examination showed entirely cured pericallosal aneurysm (RROC I) and reconstruction of the parent artery.<br />
Successful endovascular treatment of an iatrogenic pericallosal aneurysm was previously reported, and this method seems to be the first-choice treatment. In our case, endovascular stent-assisted coiling also allowed for safe exclusion from circulation of pericallosal dissecting aneurysm, and the implanted stent caused reconstruction of the parent artery, restoring the normal lumen diameter. The second endovascular treatment option considered was implantation of a flow-diverted stent into the pericallosal artery.

Published: February 2021

Článek se zabývá problematikou využití slunečního záření jako obnovitelného zdroje energie v rámci budovy bytového domu. V současné době je aktuálním trendem využívat jakékoliv ekologické obnovitelné zdroje energie. Podstatnou část těchto zdrojů energie tvoří sluneční záření. Sluneční záření je možné při návrhu budovy využít dvěma hlavními způsoby, a to buď k výrobě elektřiny pomocí fotovoltaických (FTV) panelů nebo k získávání tepla k ohřevu teplé vody pomocí solárních termických kolektorů. Fotovoltaické panely se používají pro výrobu elektrické energie díky světelnému záření. Článek se dále rovněž věnuje energetickému využití a finančnímu posouzení FTV panelů instalovaných na větrané fasádě konkrétního objektu. Benefity jsou prezentovány na konkrétní případové studii reálné stavby bytového domu.
