Authors: Prihatin Nova Sumaini , Nurmila Nurmila , Ernita Ernita , Iswani Rayana
Published: November 2022

In the United States, the prevalence of dysmenorrhea is estimated at 45-90%, while in Indonesia the prevalence of dysmenorrhea is 64.25%, consisting of 54.89% primary dysmenorrhea and 9.36% secondary. Dysmenorrhea is pain that is felt when adolescent girls menstruate. As a result, young women do not go to school. The aim is to increase the knowledge of young women about dysmenorrhea at the Misbahul Ulum Islamic Boarding School, Lhokseumawe City. The activity was carried out in three stages, namely assessment, counseling and evaluation. The target audience of Aliyah class young women is 50 participants. The results of the knowledge level of the majority of young women during the pretest were less, after socialization the level of knowledge of the majority of young women was good. Handling of dominant dysmenorrhea is done non-pharmacologically, by rubbing eucalyptus oil on the stomach. Pharmacological treatment by consuming drugs that reduce pain. As a result of dysmenorrhea, young women do not go to school, and interfere with learning concentration. It is hoped that young women can understand well the therapy used, for the Islamic boarding school to improve cooperative relationships with health services so that young women get extensive information about their reproductive health.

Hypoglycemia has a serious impact on the morbidity, mortality and quality of life of people with Diabetes Mellitus (DM). To prevent or reduce the risk of hypoglycemia, education is very important, including identification of hypoglycemia, detection of causes, prevention efforts and early treatment efforts at home. The use of mobile applications strongly supports independent health management because it is easily accessible, portable, low cost, convenient for users, and has a wide reach. This community service aims to optimize the use of the smartphone application “NEDTA” to improve the ability to identify hypoglycemia in people with diabetes mellitus in the Simpang Kawat Health Center area of Jambi City. The partners of this Community Partnership Program are the Head of Simpang Kawat Health Center, the Person in Charge of the Non-Communicable Disease Program (PTM) and 40 people with DM who meet the criteria. The methods used include socialization, competency improvement, implementation of activities, monitoring and evaluation. The results of community service revealed that more than half (58%) had diabetes for more than 10 years and most (74%) had experienced hypoglycemia. There was an increase in the ability to identify hypoglycemia after using the NEDTA smartphone application from 40% of high ability patients (pre test) to 75% (post test). The Head of the Community Health Center in charge of the non-communicable disease program at the Simpang Kawat Health Center is expected to continue mentoring activities in the use of the NEDTA application so that DM sufferers are independent in recognizing hypoglycemia, supporting the prevention and eradication of non-communicable diseases (P2PTM) such as diabetes mellitus, hypertension and other non-communicable diseases and support the PIS-PK Program.

Understanding Hari-Hari Terakhir Seorang Seniman and Arus through Goodenough Ethnosemantics Approach
Authors: Ismail Azman
Published: November 2022

This article discusses the position of the novels Hari-hari Terakhir Seorang Seniman (1979) and Arus (1985) by Anwar Ridhwan as these are considered to be cultural products and behaviors of the Malay community. Based on the interpretation of the novels, from an ethnosemantics study by Goodenough proves that cultural products (literature) are the collective knowledge system of the Malay society in the 1940s and 1970s. In these two novels, Anwar Ridhwan has created a discourse of knowledge and cultural phenomena to discuss various issues in his society. It includes three main elements which are conflict of values, psychosocial and social leadership which can be connected with knowledge system, philosophy, public thinking and cultural behavior collectively. These works can be understood through content analysis to understand the forms of thought, cultural patterns, and behavior that form the basis of a society's knowledge system which is the focus of Anwar Ridhwan's novels. Therefore, these two novels in Goodenough's ethnosemantics perspective are social facts which are the basis to understand the way of life, thinking, philosophy, common sense and cultural practices that are the core of his authorship.

The characteristics of the structure and spatial distribution of heterotrophic and autotrophic picoplankton in the lower part of the Kuibyshev reservoir in August 2014 are presented in the paper. The total abundance of picoplankton varied within (0.55–11.27) × 106 cells/ml (on average 2.96±2.13×106 cells/ml), biomass – 11.48–372, 76 µgC/l (82.51±72.85 µgC/l), which corresponded to the mesotrophic-eutrophic level of productivity. Single free-floating heterotrophic bacteria, mainly cocci and cocobacilli, predominated in picoplankton. Picocyanobacteria formed 2.2% of the abundance and 20.3% of the biomass of picoplankton; colonial forms were found only in 29.4% of the samples, and no colonies were found in the samples of the Ulyanovsk Reach and Cheremshansky Bay. During the studied period in the Kuibyshev reservoir, the spatial heterogeneity of autotrophic picoplankton in comparison with heterotrophic, was more pronounced. Our data indicate the significant role of picoplankton in the ecosystem of the Kuibyshev reservoir in the late summer period.

A Covid19-járvány következtében a nemzeti büntetés-végrehajtási szervezetekre jelentős nyomás nehezedett annak érdekében, hogy korlátozzák a vírusnak a zárt börtönkörnyezetre gyakorolt hatását. Az Európa Tanács tagországainak büntetés-végrehajtási szervezetei a vírus terjedésének megakadályozására hihetetlen gyorsasággal reagáltak és hoztak megelőző- és kezelő intézkedéseket. Az Európa Tanács, az EuroPris és más nemzetközi szervezetek célja az volt, hogy az információk és a bevált gyakorlatok (best practice) cseréjének elősegítésével támogassák a tagállamoknak a börtönökben uralkodó helyzet kezelésére irányuló válaszlépéseit. Jelen tanulmány, a terjedelmi korlátok figyelembevételével, górcső alá veszi az Európa Tanács legfontosabb szerveinek, bizottságainak nyilatkozatait, ajánlásait és az abban foglaltakat, érintőlegesen párhuzamba állítva a magyar intézkedésekkel és megoldásokkal.
Egyes „jövedéki drogok” iránti kereslet alakulása Magyarországon a Covid19 járvány első időszakában
Authors: Erdős Ákos
Published: November 2022

Bevezetés: A "jövedéki drogok" azok a pszichoaktív hatású anyagok, amelyek fogyasztása legális, de jövedéki adó terheli őket (alkoholtartalmú italok, dohánytermékek). A "jövedéki drogok" tömeges használata komplex, gazdasági, szociális és egészségügyi szempontú konzekvenciákat magán viselő társadalmi jelenség, amelyet összetett, szerteágazó entitások képesek befolyásolni. Célok: A jövedéki drogok fogyasztását – azon belül is az alkoholhasználatot – befolyásoló lehetséges tényezők közül jelen tanulmányban Covid19 humánjárvánnyal foglalkozunk. Kutatási módszerek: Jelen tanulmány eredményei szekunder adatelemzésen alapulnak. A vizsgálat időszak 2017-2021. A vizsgálat során a Statista, a Nemzeti Adó- és Vámhivatal, valamint a Központi Statisztikai Hivatal adatait használtam. Eredmények: A kutatás eredményei szerint (1) az alkoholpiac, illetve az alkoholfogyasztás volumenének csökkenését a kiskereskedelmi adatok egyike sem támasztja alá egyértelműen; (2) a járvány, illetve a bevezetett korlátozó intézkedések elsősorban nem az elfogyasztott alkohol mennyiségében, mint inkább a fogyasztói preferenciákban okozott változást; (3) az alkoholfogyasztással összefüggő bűnügyi és egészségügyi adatok szintén arra engednek következtetni, hogy az alkoholfogyasztás mértékében nem történet érdemi csökkenés Magyarországon a járvány kitörésének első évében.
A budapesti Gozsdu-udvar rendezvényei biztosításának magán és közbiztonsági aspektusai
Authors: Lippai Zsolt , Csatári Károly
Published: November 2022

Napjainkra a rendészet, mint állami monopólium paradigma túlhaladottá válásával a rendfenntartás szükségszerű pluralizálódásának, a magánbiztonság és a polgári rendfenntartás előtérbe kerülésének lehetünk tanúi, ami egyet jelent az állami rendészet monopóliumának megtörésével. Hazánk magánbiztonsági szektora a rendszerváltást követően indult fejlődésnek és mostanára már megkerülhetetlen jelentőségű szereplővé vált a közrend és a közbiztonság fenntartásában. Az egyik talán legszembetűnőbb példa, amelyben mindez tetten érhető, az a zenés-táncos rendezvények biztosításával kapcsolatos, egymást átfonó magán és közbiztonsági tevékenység megvalósulása. A szerzők, mint gyakorló rendészeti szakemberek a Budapest VII. kerület Belső-Erzsébetvárosban található, a köznyelvben „bulinegyedként” elhíresült, közkedvelt és közismert szórakozónegyed kihívásokkal terhelt mindennapjainak magán és közbiztonsági problémáit mutatják be. Tanulmányukban kiemelt helyet kap a Gozsdu-udvar története, hazai és nemzetközi példák útján a zenés-táncos rendezvények szervezésének katasztrófákkal kísért szervezési sajátosságai, a bulinegyed kapcsán érintett rendészeti szervek, magánbiztonsági szolgáltatók, a polgárőrség és a közterület-felügyelet tevékenységének a biztonság megteremtéséhez hozzáadott értékének vizsgálata.
Power System Stabilizers Design Using BAT Algorithm
Authors: Ali E. S.
Published: November 2022

A new metaheuristic method, the BAT algorithm based on the echolocation behaviour of bats is proposed in this paper for optimal design of Power System Stabilizers (PSSs) in a multimachine environment. The PSSs parameter tuning problem is converted to an optimization problem which is solved by the BAT search Algorithm. An eigenvalues based objective function involving the damping factor, and the damping ratio of the lightly damped electromechanical modes is considered for the PSSs design problem. The performance of the proposed BAT based PSSs (BATPSS) has been compared with Genetic Algorithm (GA) based PSSs (GAPSS) and the Conventional PSSs (CPSS) under various operating conditions and disturbances. The results of the proposed BATPSS are demonstrated through time domain analysis, eigenvalues and performance indices. Moreover, the results are presented to demonstrate the robustness of the proposed algorithm over the GA and conventional one.
Altered reward processing underpins emotional apathy in dementia
Authors: Wong Stephanie , Wei Grace , Husain Masud , Hodges John R. , Piguet Olivier , Irish Muireann , Kumfor Fiona
Published: November 2022

Introduction

While apathy is broadly defined as a loss of motivation, it is increasingly recognised as a multidimensional syndrome spanning executive, emotional, and initiation domains. Emotional apathy is purportedly driven by deficits in using socioemotional rewards to guide behaviour, yet the link between these symptoms and reward processing, and their common neural correlates, has not been directly examined.

Methods

Sixty-four patients (33 behavioural-variant frontotemporal dementia, 14 Alzheimer’s disease, 8 semantic dementia, 6 progressive nonfluent aphasia, 3 logopenic progressive aphasia) were classified into high (HEA; n = 36) and low (LEA; n = 28) emotional apathy groups based on emotional apathy subscale scores on the Dimensional Apathy Scale. Patients and age-matched healthy controls (n = 27) performed an instrumental reward learning task where they learned to associate cues with either social or monetary outcomes.

Results

HEA patients showed impaired learning on both the social and monetary reward conditions, relative to LEA patients (p = 0.016) and controls (p = 0.005). Conversely, the LEA group did not differ from controls (p = 0.925). Importantly, multiple regression analyses indicated that social reward learning significantly predicted emotional apathy. Voxel-based morphometry analyses revealed that emotional apathy and social reward learning were both associated with orbitofrontal cortex, ventral striatum, and insula atrophy.

Discussion

Our results demonstrate a unique link between impaired social reward learning and emotional apathy in dementia and reveal a shared neurobiological basis. Greater understanding of these neurocognitive mechanisms of reward processing will help improve the identification of emotional apathy in dementia and inform the development of novel interventions to address these symptoms.
Revisiting the bromination of 3β-hydroxycholest-5-ene with CBr4/PPh3 and the subsequent azidolysis of the resulting bromide, disparity in stereochemical behavior
Authors: Schumacher Christian , Ward Jas S , Rissanen Kari , Bolm Carsten , Aly Mohamed Ramadan El Sayed
Published: November 2022

Cholesterol reacts under Appel conditions (CBr4/PPh3) to give 3,5-cholestadiene (elimination) and 3b-bromocholest-5-ene (substitution with retention of configuration). Thus, the bromination of cholesterol deviates from the stereochemistry of the standard Appel mechanism due to participation of the D5 π-electrons. In contrast, the subsequent azidolysis (NaN3/DMF) of 3b-bromocholest-5-ene proceeds predominantly by Walden inversion (SN2) affording 3a-azidocholest-5-ene. The structures of all relevant products were revealed by X-ray single crystal structure analyses, and the NMR data are in agreement to the reported ones. In light of these findings, we herein correct the previous stereochemical assignments reported by one of us in the Beilstein J. Org. Chem. 2015, 11, 1922–1932 and the Monatsh. Chem. 2018, 149, 505–517.

Refinement of educational goals of workplace writing: Focusing on content corresponding to the basic physical strength of workplace writing
Authors:   Korean Association for Literacy, Yim Taekkyun
Published: November 2022

This study aims to specify a common writing goal that corresponds to the basic physical strength of workplace writing. To reflect the situation and context of the job discourse community, 12 job-related writing self-development books used by office workers in real society were analyzed. Approximately 300 people across the country participated in a questionnaire survey on this information, and the implicit theory for workplace writing was explored by performing a common factor analysis on the questionnaire responses. The results demonstrated that the writing ability commonly required for workplace writing can be divided into content related to “logic and concise,” “idea composition,” and “writing structure and form.” This study is meaningful as it provides a foundation for more practical workplace writing education for the following reasons: (1) it was derived based on the content required for workplace writing used in job sites, and (2) it revealed a more specific level of detail than the existing discussions on workplace writing.

Effect of Catheter and Stenosis on Solute Diffusion in Non-Newtonian Blood Flow through a Catheterized Stenosed Artery
Authors: Intan Diyana Munir  , Nurul Aini Jaafar  , Sharidan Shafie
Published: November 2022

The presence of stenosis at the wall of the artery lead to further cardiovascular diseases such as heart attack, stroke and many more. Treatment of a stenosed artery includes the insertion of a catheter through the artery which affects the blood flow and solute dispersion. This present study focuses on the effect of catheter radius and stenosis height on the blood flow and solute dispersion behavior. The problem is modelled using the Herschel-Bulkley fluid to represent the blood rheology, with catheter and stenosis as the boundary conditions. Analytical solutions in integral form are obtained by solving the momentum equation and Herschel-Bulkley constitutive equation. The integrals are numerically evaluated using the Simpson’s 3/8 rule and Regula-Falsi method to obtain the blood velocity. The obtained velocity is employed into the unsteady convective-diffusion equation and solved using the generalized dispersion model (GDM) to analyse the behaviour of solute diffusion. The influence of catheter radius and stenosis height on the diffusion coefficient and mean concentration of solute are observed. Results show that the diffusion coefficient decreases as the catheter radius and stenosis height increases. A decrease in diffusion coefficient simultaneously increases the solute mean concentration.

Published: November 2022

This paper examines the flow of Brinkman-viscoelastic fluid in the boundary layer region. The flow over a Horizontal Circular Cylinder (HCC) is investigated theoretically. The proposed model’s governing equations, which are partial differential equations (PDEs), are transformed to their simplest form by using the appropriate non-dimensional variables and non-similarity transformation. The numerical computations for the obtained equations are then computed using the Keller-box method (KBM) which is programmed in MATLAB R2019a software. The velocity distribution results, together with the coefficient of skin friction are presented. A comparison study with previously published results is carried out to ensure that the current findings are accurate. It is discovered that the presence of the Brinkman and viscoelastic parameters influences the velocity behaviour of fluid, with a tendency to decrease the velocity distribution of fluid. Furthermore, both parameters have the potential to decrease the skin friction coefficient. The output can be used as a starting point for complex flow problems that occur frequently in engineering applications.

Published: November 2022

Floating garbage in a filtration system is one of the main factors causing many problems in engineering structures because the accumulation of garbage can block the flow rate. The bar screen installed in a water channel is used to catch the garbage, but the main threat when installing a bar screen in a water channel (intakes) is that system can lead to headloss and disturb (block) fluid flow occurrence. However, there is no concern about the effect of garbage level on the bar screen to head losses and water discharge; for the filtration system, the main concern is discharge. Therefore, this study aims to investigate the effect of garbage level on bar screens to head losses and water discharge by the computational fluid dynamics (CFD) method. Based on the results, the CFD method is capable of predicting the headloss and discharge for the filtration system in the channel. However, the headloss that occurred was insignificant (as still normal) and can reduce the water discharge from the inlet by more than 45%. Then, water energy dissipation due to the narrowing of the flow field consequence of the blockade of garbage. Then, estimating discharge in a filtration system connected to the high seas requires tidal analysis because tides affect the headloss and the water discharge. Further, the headloss is directly proportional to the flow speed and the channel's width.
On the Formation of the Public Condemnation of Epoch-making Korean Poet Sŏ Chŏngju – With a Focus on Pro-Japanese Collaboration
Authors: Kovács Janka
Published: November 2022

Sŏ Chŏngju is no doubt one of the most significant poets of 20th century Korean literature. However, his figure is shrouded in controversies originating from his political choices in life. The first of these controversies is his being a ‘pro-Japanese collaborator’ during the Japanese colonial period. The purpose of this study is to move beyond the accusation of Sŏ Chŏngju being an collaborator to map the settings of the colonial background in which he lived and wrote, while also comparing his situation with that of the famous writer, I Kwangsu. Another goal of the study is to examine the approach to his figure and works in recent times. This is for the sake of gaining a deeper understanding of the important poet, who very often is cast away by the superficial criticism of his being a ‘collaborator’.
Evolution, Structure, and Topology of Self-generated Turbulent Reconnection Layers

Published: November 2022

We present a 3D MHD simulation of two merging flux ropes exhibiting self-generated and self-sustaining turbulent reconnection (SGTR) that is fully 3D and fast. The exploration of SGTR is crucial for understanding the relationship between MHD turbulence and magnetic reconnection in astrophysical contexts including the solar corona. We investigate the pathway toward SGTR and apply novel tools to analyze the structure and topology of the reconnection layer. The simulation proceeds from 2.5D Sweet–Parker reconnection to 2.5D nonlinear tearing, followed by a dynamic transition to a final SGTR phase that is globally quasi-stationary. The transition phase is dominated by a kink instability of a large “cat-eye” flux rope and the proliferation of a broad stochastic layer. The reconnection layer has two general characteristic thickness scales, which correlate with the reconnection rate and differ by a factor of approximately six: an inner scale corresponding with current and vorticity densities, turbulent fluctuations, and outflow jets, and an outer scale associated with field line stochasticity. The effective thickness of the reconnection layer is the inner scale of the effective reconnection electric field produced by turbulent fluctuations, not the stochastic thickness. The dynamics within the reconnection layer are closely linked with flux rope structures that are highly topologically complicated. Explorations of the flux rope structures and distinctive intermediate regions between the inner core and stochastic separatrices (“SGTR wings”) are potentially key to understanding SGTR. The study concludes with a discussion on the apparent dualism between plasmoid-mediated and stochastic perspectives on SGTR.

We present the results of the analysis of the photometric data collected in long- and short-cadence mode by the Transiting Exoplanet Survey Satellite for GJ 504, a well-studied planet-hosting solar-like star, whose fundamental parameters have been largely debated during the last decade. Several attempts have been made by the present authors to isolate the oscillatory properties expected on this main-sequence star, but we did not find any presence of solar-like pulsations. The suppression of the amplitude of the acoustic modes can be explained by the high level of magnetic activity revealed for this target, not only by the study of the photometric light curve but also by the analysis of three decades of available Mount Wilson spectroscopic data. In particular, our measurements of the stellar rotational period P
rot ≃ 3.4 days and of the main principal magnetic cycle of ≃12 yr confirm previous findings and allow us to locate this star in the early main-sequence phase of its evolution during which the chromospheric activity is dominated by the superposition of several cycles before the transition to the phase of the magnetic-braking shutdown with the subsequent decrease of the magnetic activity.
Flexible Models for Galaxy Star Formation Histories Both Shift and Scramble the Optical Color–Mass-to-light Ratio (M/L) Relationship
Authors: Li 李 Yijia 轶佳 , Leja Joel
Published: November 2022

The remarkably tight relationship between galaxy optical color and stellar mass-to-light ratio (M
*/L) is widely used for efficient stellar mass estimates. However, it remains unclear whether this low scatter comes from a natural order in the galaxy population, or whether it is driven by simple relationships in the models used to describe them. In this work, we investigate the origins of the relationship by contrasting the derived relationship from a simple 4 parameter spectral energy distribution (SED) model with a more sophisticated 14D Prospector–α model including nonparametric star formation histories (SFHs). We apply these models to 63,430 galaxies at 0.5 < z < 3 and fit a hierarchical Bayesian model (HBM) to the population distribution in the (g − r)–

plane. We find that Prospector–α infers systematically higher M
*/L by 0.12 dex, a result of nonparametric SFHs producing older ages, and also systematically redder rest frame (g − r) by 0.06 mag owing to the contribution from nebular emission. Surprisingly, the combined effects of the M
*/L and (g − r) offsets produce a similar average relationship for the two models; though Prospector–α produces a higher scatter of 0.28 dex compared to the simple model of 0.12 dex. Also, unlike the simple model, the Prospector–α relationship shows substantial redshift evolution due to stellar aging. These expected and testable effects produce overall older and redder galaxies; though the color–M
*/L relationship is measured only at 0.5 < z < 3. Finally, we demonstrate that the HBM produces substantial shrinkage in the individual posteriors of faint galaxies, an important first step toward using the observed galaxy population directly to inform the SED-fitting priors.

Planetary climates are strongly affected by planetary orbital parameters such as obliquity, eccentricity, and precession. In exoplanetary systems, exoterrestrial planets should have various obliquities. High-obliquity planets would have extreme seasonal cycles due to the seasonal change of the distribution of the insolation. Here, we introduce the Non-hydrostatic ICosahedral Atmospheric Model (NICAM), a global cloud-resolving model, to investigate the climate of high-obliquity planets. This model can explicitly simulate a three-dimensional cloud distribution and vertical transports of water vapor. We simulated exoterrestrial climates with high resolution using the supercomputer FUGAKU. We assumed aqua-planet configurations with 1 bar of air as a background atmosphere, with four different obliquities (0°, 23.5°, 45°, and 60°). We ran two sets of simulations: (1) low resolution (∼220 km mesh as the standard resolution of a general circulation model for exoplanetary science) with parameterization for cloud formation, and (2) high resolution (∼14 km mesh) with an explicit cloud microphysics scheme. Results suggest that high-resolution simulations with an explicit treatment of cloud microphysics reveal warmer climates due to less low cloud fraction and a large amount of water vapor in the atmosphere. It implies that treatments of cloud-related processes lead to a difference between different resolutions in climatic regimes in cases with high obliquities.
Spectroscopic Confirmation of Two X-Ray Diffuse and Massive Galaxy Clusters at Low Redshift
Authors: Chen Kaiyuan , Xu Weiwei , Jiang Linhua
Published: November 2022

We present MMT spectroscopic observations of two massive galaxy cluster candidates at redshift z ∼ 0.07 that show extended and diffuse X-ray emission in the ROSAT All-Sky Survey (RASS) images. The targets were selected from a previous catalog of 303 newly identified cluster candidates with the similar properties using the intracluster medium emission. Using the new MMT Hectospec data and Sloan Digital Sky Survey archival spectra, we identify a number of member galaxies for the two targets and confirm that they are galaxy clusters at z = 0.079 and 0.067, respectively. The size of the two clusters, calculated from the distribution of the member galaxies, is roughly 2 Mpc in radius. We estimate cluster masses using three methods based on their galaxy number overdensities, galaxy velocity dispersions, and X-ray emission. The overdensity-based masses are (6 ∼ 8) × 1014
M
⊙, comparable to the masses of large clusters at low redshift. The masses derived from velocity dispersions are significantly lower, likely due to their diffuse and low concentration features. Our result suggests the existence of a population of large clusters with very diffuse X-ray emission that has been missed by most previous searches using the RASS images. If most of the 303 candidates in the previous catalog are confirmed to be real clusters, this may help to reduce the discrepancy of cosmological results between the cosmic microwave background and galaxy cluster measurements.
Polarization Observations of a Split-band Type II Radio Burst from the Solar Corona
Authors: Ramesh R. , Kathiravan C.
Published: November 2022

Using temporal observations of circular polarized harmonic plasma emission from a split-band type II solar radio burst at 80 MHz, we separately estimated the coronal magnetic field strengths (B) associated with the lower (L) and upper (U) frequency bands of the burst. The corresponding Stokes I and V data were obtained with the polarimeter operating at the above frequency in the Gauribidanur observatory. The burst was associated with a flare/coronal mass ejection on the solar disk. Simultaneous spectral observations with the spectrograph there in the frequency range 80–35 MHz helped to establish that the observed polarized emission was from the harmonic component of the burst. The B values corresponding to the polarized emission from the L and U bands at 80 MHz are B

L
≈ 1.2 G and B

U
≈ 2.4 G, respectively. The different values of B for the observed harmonic emission at the same frequency (80 MHz) from the two bands imply unambiguously that the corresponding fundamental emission at 40 MHz must have originated at different spatial locations. Two-dimensional radio imaging observations of the burst with the radioheliograph in the same observatory at 80 MHz indicate the same. As comparatively higher B is expected behind a propagating shock due to compression as well as the corresponding coronal regions being closer to the Sun, our results indicate that the sources of L- and U-band emission should be located ahead of and behind the associated coronal shock, respectively. These are useful to understand the pre- and postshock corona as well as locations of electron acceleration in a propagating shock.

BACKGROUND: Detection of positive 2019-nCoV nucleic acids by real-time reverse transcriptase-polymerase chain reaction (rRT-PCR)-based assays performed on the upper and lower respiratory samples remains the gold standard for the diagnosis of COVID-19. However, antigen-detecting rapid diagnostic tests can offer a faster (15–30 min) and less expensive way to diagnose active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than nucleic acid amplification tests.

AIM: Hence, the present study aimed to compare and evaluate the results of different SARS-CoV-2 rapid point-of-care antigen tests with SARS-CoV-2 PCR as a reference method.

METHODS: Sixty-five nasopharyngeal swab specimens were collected from attendees of the Reference Laboratory of Egyptian university hospitals. The samples were placed in viral transport medium for RNA extraction. The remaining part of the suspension was stored at −70°C until use for COVID-19 antigen testing. All samples were processed for the COVID-19 Ag rapid test and RT-PCR simultaneously.

RESULTS: RT-PCR assay revealed 46 (70.8%) positive samples and 19 (29.2%) negative samples for COVID-19. All eight rapid antigen assays indicated specificity and positive predictive value of 100% each. As for the other parameters, the sensitivity, negative predictive value (NPV), and accuracy ranged from 43.8 to 93.8, 33.3 to 90, and 60 to 96, respectively. Biozak exhibited the best performance with the highest sensitivities 91.3, 81.8, and 93.75, respectively, while Viro and Standard Q were the worst among the tested kits with sensitivity, NPV, and accuracy of 50, 33.3, and 60 each. Regarding the relationship between the viral load of COVID-19 detected by RT-PCR and the results of the eight rapid antigen tests (RAT), we deduced that the higher the viral load, the better the sensitivity observed.

CONCLUSION: The RATs used, in our study, exhibited heterogeneous diagnostic performance, where some of them showed very promising results in comparison to the reference RT-PCR assay.
