Authors: Morrison Shawnda A. , Meh Kaja , Sember Vedrana , Starc Gregor , Jurak Gregor 
Published: December 2021

Background: The negative impact of isolation, confinement, and physical (in)activity due to pandemic movement restriction has been well-documented over the past year, but less is known on the impact of these policies on children's physical fitness. This study was designed to determine the effects of pandemic movement restriction policies on the 24-hour movement behavior (24-HMB) of children, and whether any alterations are reflected in worsening physical fitness outcomes determined via direct testing.Methods: A two-phase, repeated-measures study with matched controls was conducted. Phase One: N = 62 schoolchildren (N = 31 female) completed self-assessment questionnaires on 24-HMB in October 2018 (pre-pandemic) and again in April 2020, at the height of movement restrictions enacted in response to the COVID-19 pandemic first wave. Phase Two: physical fitness of the original N = 62 children were determined directly pre- and post-isolation using an eight-component standardized fitness test battery and compared to N = 62 control children who were matched for age, sex, school region, and fitness centile scores.Results: During lockdown (total duration: 63 days), moderate-to-vigorous physical activity (MVPA) decreased by ~46 min per day, screen time demonstrated a significant interaction effect, such that kids reported spending less recreational screen time on weekends during lockdown compared to no restriction, and sleep duration was consistently lower (95% CI: −104.1 to −45.5 min, p &lt; 0.001). No interaction effect was present for direct fitness indicators, including: hand tapping (reaction time), standing broad jump, polygon backward obstacle course (coordination), sit-ups, stand-and-reach, bent-arm hang, 60-m, and 600-m run (p ≥ 0.05) although significant main effects are noted for both sexes.Conclusion: Initial changes in 24-HMB did not translate to reductions in physical fitness per se, likely due to the high initial fitness levels of the children. Further work is needed to confirm whether longer or repeated movement restrictions exacerbate initial negative 24-HMB trends, especially for children who are less fit when restrictions are initiated, prolonged, or repeated.

Published: December 2021

Study Objective: This study aimed to investigate whether stroke volume variation (SVV)-guided goal-directed therapy (GDT) can improve postoperative outcomes in elderly patients undergoing minimally invasive esophagectomy (MIE) compared with conventional care.Design: A prospective, randomized, controlled study.Setting: A single tertiary care center with a study period from November 2017 to December 2018.Patients: Patients over 65 years old who were scheduled for elective MIE.Interventions: The GDT protocol included a baseline fluid supplement of 7 ml/kg/h Ringer's lactate solution and SVV optimization using colloid boluses assessed by pulse-contour analysis (PiCCO™). When SVV exceeded 11%, colloid was infused at a rate of 50 ml per minute; if SVV returned below 9% for at least 2 minutes, then colloid was stopped.Measurements: The primary outcome was the incidence of postoperative complications before discharge, as assessed using a predefined list, including postoperative anastomotic leakage, postoperative hoarseness, postoperative pulmonary complications, chylothorax, myocardial injury, and all-cause mortality.Main Results: Sixty-five patients were included in the analysis. The incidence of postoperative complications between groups was similar (GDT 36.4% vs. control 37.5%, P = 0.92). The total fluid volume was not significantly different between the two groups (2,192 ± 469 vs. 2,201 ± 337 ml, P = 0.92). Compared with those in the control group (n = 32), patients in the GDT group (n = 33) received more colloids intraoperatively (874 ± 369 vs. 270 ± 67 ml, P &lt;0.05) and less crystalloid fluid (1,318 ± 386 vs. 1,937 ± 334 ml, P &lt;0.05).Conclusion: The colloid-based SVV optimization during GDT did not significantly reduce the incidence of early postoperative complications after minimally invasive esophagectomy in elderly patients.Clinical Trial Number and Registry URL: ChiCTR-INR-17013352; http://www.chictr.org.cn/showproj.aspx?proj=22883
Use of Bacteria Externally for Repairing Cracks and Improving Properties of Concrete Exposed to High Temperatures

Published: December 2021

The current paper presents the results of an experimental study on the application of calcium carbonate precipitation bacteria as a new approach to repairing damaged concrete when exposed to high temperatures. To do so, cylindrical and cubic concrete specimens were initially exposed to heat in a furnace for 1 h, after reaching two different temperatures of 600 and 800 °C. A heat rate of 5.5 °C per minute was used to achieve the target temperatures. Then, two types of bacteria, namely Sporosarcina pasteurii and Bacillus sphaericus, with cell concentration of 107 cells/mL, were utilized externally, to repair the thermal cracks, enhancing the mechanical properties and durability of the damaged concrete. The efficiency of the bacterial remediation technique was then evaluated through compressive strength, ultrasonic pulse velocity (UPV), and electrical conductivity tests on the control specimens (unexposed to heat), and those exposed to high temperature with or without bacterial healing. The experimental results demonstrate that the compressive strength of the test specimens exposed to temperatures of 600 and 800 °C decreased by about 31–44% compared with the control ones. However, compared to those damaged at 600 and 800 °C, the compressive strength of specimens repaired by the S. pasteurii and the B. sphaericus showed increases of 31–93%. This increase is associated with the precipitation of calcium carbonate in the deep and superficial cracks and pores of the damaged specimens. Furthermore, the ultrasonic pulse velocity of the specimens subjected to bacterial remediation had a significant increase of about 1.65–3.47 times compared with the damaged ones. In addition, the electrical conductivity of repaired specimens decreased by 22–36% compared with the damaged specimens.

Published: December 2021

Activation of thyroid hormone receptor β (THRβ) has shown beneficial effects on metabolic alterations, including non-alcoholic fatty liver disease (NAFLD). Here, we investigated the effect of TG68, a novel THRβ agonist, on fatty liver accumulation and liver injury in mice fed a high-fat diet (HFD). C57BL/6 mice fed HFD for 17 or 18 weeks, a time when all mice developed massive steatohepatitis, were then given TG68 at a dose of 9.35 or 2.8 mg/kg for 2 or 3 weeks, respectively. As a reference compound, the same treatment was adopted using equimolar doses of MGL-3196, a selective THRβ agonist currently in clinical phase III. The results showed that treatment with TG68 led to a reduction in liver weight, hepatic steatosis, serum transaminases, and circulating triglycerides. qRT-PCR analyses demonstrated activation of THRβ, as confirmed by increased mRNA levels of Deiodinase-1 and Malic enzyme-1, and changes in lipid metabolism, as revealed by increased expression of Acyl-CoA Oxidase-1 and Carnitine palmitoyltransferase-1. The present results showed that this novel THRβ agonist exerts an anti-steatogenic effect coupled with amelioration of liver injury in the absence of extra-hepatic side effects, suggesting that TG68 may represent a useful tool for the treatment of NAFLD.
Ultrafast phased-array imaging with pump excitation for closed-crack imaging
Authors: Ohara Yoshikazu , Haupert Sylvain , Li Sinan 
Published: December 2021

Abstract
Nondestructive evaluation of closed cracks is one of the most challenging problems in ultrasonic testing. Here, we propose a novel closed-crack imaging technique combining ultrafast phased-array with pump excitation. The pump excitation with kHz frequency can effectively induce the crack opening/closing behaviors since it can generate a large displacement of 1000 nm order. At the same time, ultrafast phased-array imaging, i.e. plane wave imaging, with MHz frequency stroboscopically captures the high-speed crack dynamics induced by pump excitation. We successfully proved the concept in a closed fatigue crack specimen.

<p>Epilepsy affect almost 1% of the worldwide population. An early diagnosis of seizure types is a</p>

<p>relies on the correct identification of the seizure type. As such, identifying the seizure type has the</p>
<p>biggest immediate influence on therapy than the seizure detection, reducing the neurologist’s efforts</p>
<p>when reading and detecting seizures in EEG recordings. Most of the existing seizure detection and</p>
<p>classification methods are conceptualized following the patient-dependent schema thus fail to perform</p>
<p>well with unknown cases. Our work focuses on patient-independent schema for seizure type classification</p>
<p>and pays more attention to the explainability of the underlying attention mechanism of our method.</p>
<p>Using a channel-wise attention mechanism, a quantification of the EEG channels contribution is enabled.</p>
<p>Therefore, results become more interpretable and a visualization of brain lobes contribution by seizure</p>

Published: December 2021

We report flash C-H chlorination of ethylene carbonate, which gives chloroethylene carbonate, a precursor to ethylene carbonate. A novel photoflow setup designed for a gas-liquid biphasic reaction turned out to be useful for the direct use of chlorine gas in flow. The setup employed sloped channels so as to make the liquid phase thinner, ensuring high surface to volume ratio. When ethylene carbonate was introduced to the reactor, the residence time was measured to be 15 or 30 sec, depending on the slope of the reactor to be 15 or 5 °C, respectively. Such short time exposition sufficed the photo C-H chlorination. The partial irradiation of the flow channels sufficed for the C-H chlorination, which is consistent with the requirement of photoirradiation for the purpose of radical initiation. We also found that the contaminated water negatively influenced the performance of C-H chlorination. The 100% selectivity for single chlorination required the low conversion of ethylene carbonate such as 9%, which was controlled by limited introduction of chlorine gas. At a higher conversion of ethylene carbonate such as 63%, the selectivity for mono-chlorinated ethylene carbonate over di-chlorinated ethylene carbonate was 86%. We found that the contaminated water negatively influenced the performance of the C-H chlorination.
Kosova’ya Yapılan Çerkes Göçü ve İskânı (1864-1865)
Authors: Urhan Vahit Cemil 
Published: December 2021

XVI. yüzyıldan itibaren Kafkasya’yı hâkimiyeti altına almaya yönelik bir politika izlemeye başlayan ve 1864 yılında Kuzey Kafkasya’yı işgal eden Rusya, bölgede yaşayan Çerkesleri Osmanlı Devleti topraklarına göç etmeye zorlamıştır. 1850’lerde başlayan Çerkes göçleri 1862-1865 yılları arasında yoğunlaşmış ve 1860’ların sonuna kadar devam etmiştir. Sürekli isyanların yaşandığı Balkanlar’da Çerkeslerin savaşçılığından yararlanmak ve Müslüman nüfusunu arttırmak isteyen Osmanlı Devleti, bu dönemde 400.000’den fazla Çerkes’i Rumeli’ye yerleştirmiştir. 9.000-11.000 civarında Çerkes de Kosova’ya iskân edilmiştir. Kosova’ya gelen Çerkesler burada köyler kurmuşlardır. Yeni vatanlarında tarım ve hayvancılıkla uğraşmaya başlamışlardır. Ancak, Kosova’ya yerleştirilen Çerkeslerin büyük bir kısmı burada kalıcı olmamıştır. Avrupa devletlerinin 23 Aralık 1876’da toplanan İstanbul Konferansı’nda Çerkeslerin Balkanlar’ı terk etmesini istemesi ve 1877-1878 Osmanlı-Rus Savaşı, Kosova’da yaşayan Çerkeslerin bir kısmının Anadolu’ya ve Ortadoğu’ya göç etmesine sebep olmuştur. Kosova’da geriye kalan Çerkeslerin büyük çoğunluğu da Balkan Savaşları sırasında ve sonrasında bölgeden ayrılmıştır.
Bu çalışmada, 1864-1865 yıllarında Kosova’ya yapılan Çerkes göçü ve iskânını hazırlayan gelişmeler, göç ve iskân sırasında karşılaşılan sorunlar ve bu sorunların çözümü için izlenen politikalar ele alınmıştır.

On the Identification of Individual Gravitational-wave Image Types of a Lensed System Using Higher-order Modes

Published: December 2021

Abstract
Similarly to light, gravitational waves can be gravitationally lensed as they propagate near massive astrophysical objects such as galaxies, stars, or black holes. In recent years, forecasts have suggested a reasonable chance of strong gravitational-wave lensing detections with the LIGO–Virgo–KAGRA detector network at design sensitivity. As a consequence, methods to analyze lensed detections have seen rapid development. However, the impact of higher-order modes on the lensing analyses is still under investigation. In this work, we show that the presence of higher-order modes enables the identification of individual image types for the observed gravitational-wave events when two lensed images are detected, which would lead to unambiguous confirmation of lensing. In addition, we show that higher-order mode content can be analyzed more accurately with strongly lensed gravitational-wave events.
L’espace en tant que facilitateur d’innovation ouverte en PME : le cas du Demos Lab
Authors: Gardet Romane , Saives Anne-Laure , Camus Annie 
Published: December 2021

Cet article expose une recherche exploratoire menée dans une PME norvégienne orientée vers la transition écologique, ayant fait de l’innovation ouverte (IO) son mode de fonctionnement et souhaitant créer un espace physique créatif et innovant pour mener ses projets. Une étude de cas, fondée sur une démarche inspirée de la résolution créative de problème (CPS) et de techniques projectives auprès d’une douzaine d’usagers potentiels a permis d’identifier les propriétés décisives d’un tel espace de travail en contexte d’IO parmi 6 dimensions repérées dans la littérature : singularité, caractère organisé et organisant, flexibilité, hétérogénéité, tiers-lieu et exemplarité. Dans la PME responsable étudiée, les résultats indiquent un lien évident entre espace physique de travail et approche managériale et soulignent l’importance de 3 conditions spatiales et managériales pour une créativité « ouverte » au service de l’IO durable : la singularité/authenticité, l’organisé/organisant au service du sentiment de maîtrise, et le design biophilique au service du projet d’innovation inclusif.

Invoquer le Nom de Jésus, une dévotion risquée
Authors: Gueullette Jean-Marie 
Published: December 2021

Attestée dès le Nouveau Testament, l’invocation du Nom de Jésus est une forme de prière qui est présente tout au long de l’histoire chrétienne. Elle peut être envisagée selon trois modalités : la contemplation, la démarche thérapeutique, ou l’invocation en vue du salut. Cependant, elle n’est pas sans soulever de questions théologiques, et aussi bien l’Occident que l’Orient ont connu des conflits assez vifs à son sujet. Les dérives qui étaient dénoncées ne sont pas tant à identifier à de la magie, car les croyants n’imaginaient pas acquérir un pouvoir sur Dieu par l’invocation du Nom, qu’à une forme d’idolâtrie dans laquelle une réalité créée prend la place de Dieu, dans laquelle un mot prend la place de celui qu’il désigne.
L’exégèse platonicienne et chrétienne du Timée 39e7-9 : Atticus, Justin et Valentin
Authors: Jurasz Izabela 
Published: December 2021

L’article propose d’examiner un cas particulier du rapport entre la métaphysique médio-platonicienne et la doctrine chrétienne de la moitié du ii e siècle, en mettant en rapport trois auteurs appartenant à la même génération : Atticus, Justin et Valentin. Atticus est auteur d’une interprétation singulière du Timée 39e7-9, selon laquelle le Modèle intelligible, dont le Démiurge use pour former le monde, est situé en dehors et au-dessous du Démiurge. Cette disposition, critiquée et abandonnée par les néoplatoniciens, semble cependant connaître un certain succès chez les chrétiens, cherchant à décrire le rapport entre le Dieu Créateur et son Logos-Fils. En ajoutant abondamment des expressions bibliques au vocabulaire platonicien, Justin et Valentin – chacun à sa façon – montrent que l’inspiration platonicienne dans la théologie chrétienne peut se faire de manière très subtile et très variée.

Authors: Hughes Monica J. 
Published: December 2021

Background:
Nursing students have high risk factors for stress, and the coronavirus disease 2019 pandemic underscored weaknesses in mitigating nursing student stress and supporting well-being. Occupational health uses proven frameworks and perspectives for understanding and mitigating health risks, and promoting worker wellness. Nurse educators can draw from this knowledge to implement system-level changes in support of a safe and healthy learning environment.

Method:
This article describes the use of an occupational health strategy to create healthier educational environments.

Results:
Applying occupational health concepts to nursing education supports honest appraisal of mental health dangers to students, offers keys to managing student health risks, and provides effective approaches for communicating risks with mitigation tactics.

Conclusion:

An occupational health and safety perspective creates a lens through which nursing stress resulting from the pandemic can be viewed and managed creatively using a holistic approach to mitigate harm from stress in the nursing educational setting.
