Authors: Iqbal Rashid , Muhammad Javaid Asad  , Saima Siddiqi  , Raja Tahir Mahmood  , Muhamamd Baseer Shah  , Admin
Published: October 2021

Objective: To examine clinical features, biochemical markers, demographic features, antecedent infections, frequency and treatment strategies.
Methods: This case-control study was conducted at Pakistan Institute of Medical Sciences (PIMS), Islamabad, Pakistan and District Headquarters Hospital (DHQ), Rawalpindi, Pakistan from 2018 to 2020. Ninety consecutive patients of Guillain-Barré syndrome (GBS) and 77 healthy controls were enrolled. Patients were diagnosed by clinical presentation, Nerve conduction study (NCS), Electromyography (EMG), Cerebrospinal fluid analysis (CSF) and biochemical profile. Data was analyzed on IBM SPSS version 23.
Results: Symmetrical ascending weakness was the striking clinical feature. Mean age was 40.20±14.90 years and male to female ratio was 2.1:1. Acute inflammatory demyelinating polyneuropathy (AIDP) was found to be the most common electrophysiological variant of GBS (46%). There was considerable difference in Interleukin-17(IL-17) levels between GBS patients 23.12 ± 3.41 pg/ml and healthy controls 8.82 ± 2.49. Mean IL-17 level was markedly increased in GBS patients, P=0.006, P<0.05. Gastrointestinal infection was the most common preceding infection (56.66%). Mean CSF protein was 100.83 g/dl with ± 51.32 standard deviation and albumio cytologic dissociation (ACD) was different in all four variants of GBS, P= 0.005.
Conclusion: GBS was presented by all ages. Males were more affected than females. About two third of GBS patients showed an antecedent infection before GBS onset. Increased levels of cytokine (IL-17) showed involvement of autoimmunity. ACD differentiated it from poliomyelitis. Plasmapheresis and intravenous immunoglobulin (IVIG) therapy were used to treat patients.

Published: October 2021

We present a patient who was admitted to the emergency room due to unstable angina, with an initial electrocardiogram without signs of acute ischemia and a favorable clinical evolution. During hospitalization, she developed the Wellens electrocardiographic pattern, noted in the literature as an infrequent, poorly identified finding and with an ominous prognosis. This electrocardiographic pattern is described in precordial derivatives, suggesting a significant lesion of a principal epicardial artery; our patient had similar electrocardiographic alterations in the high lateral leads, in whom the coronary bifurcation lesion not previously described in this scenario was confirmed.

Published: October 2021

We present the case of a 38-year-old male with a diagnosis of Stanford A aortic dissection and associated coarctation of the thoracic aorta. Acute dissection associated with coarctation of the aorta is a rare problem and difficult to manage surgically. Establishing a cardiopulmonary bypass (CPB) with adequate flows is the main objective of the procedure; optimal cannulation ensures the protection of cerebral and visceral organs. We successfully performed aortic valve re-implantation surgery (T. David Surgery), replacement of the ascending aorta and aortic arch, as well as debranching of the supra-aortic trunks. The cannulation technique was axillary and femoral to guarantee flows through the coarctation area.

Published: October 2021

Los síndromes cromosómicos más frecuentes (Down, Patau, Edwards, Turner y Williams) afectan de diversas formas a la población pediátrica, y las cardiopatías congénitas asociadas explican la compleja calidad de vida que padecen; sin embargo, no se cuenta con muchos estudios que hagan una revisión acerca de las principales anomalías cardiacas en estos síndromes, y los que existen son publicaciones de décadas pasadas. Se hizo una revisión en bases de datos como MEDLINE, LILACS, SCIELO y Google Scholar, para seleccionar la mejor evidencia posible; cada síndrome cromosómico se investigó en relación con cardiopatías congénitas, por separado, y se organizaron cinco grupos de búsqueda. El artículo muestra las características de cada una de las cardiopatías asociadas que fueron descritas en los estudios revisados, información relevante de cada estudio (autor, fecha de publicación, país y población estudiada), además de una breve descripción que consigna la frecuencia de la cardiopatía y su mortalidad. Se contrastaron los resultados descritos en esta revisión, con literatura previa ya existente con la finalidad de verificar la existencia de correspondencia entre las frecuencias reportadas. Las cardiopatías congénitas más frecuentes fueron: defecto septal atrioventricular (DSAV), comunicación interventricular (CIV), comunicación interauricular (CIA) y persistencia de conducto arterioso (PCA) en el síndrome Down; PCA, CIA y CIV en el síndrome Patau; DSAV, PCA y defectos multivalvulares en el síndrome Edwards; aorta bicúspide, coartación de aorta y estenosis aórtica en el síndrome de Turner, y estenosis aórtica supravalvar y estenosis pulmonar en el síndrome Williams.
Decolonizing the Postcolony: Of Men, Spatial Politics and the New Nation in wa Thiongo‟s Wizard of the Crow
Authors: Sam Christabel Aba
Published: October 2021

The advent of democracy – and in particular multi-party democracy – was thought to be relieving for Africa, especially in terms of the desire to undo the damage of colonialism. A careful look at Postcolonial Africa today, relative to the desire for economic and political freedom, reveals conditions that suggest that not much progress has been made. Ngugi wa Thiongo‘s Wizard of the Crow blatantly explores Africa‘s complicity in a seemingly cyclic colonization in the 21st century and its attendant consequences for the total liberation of Postcolonial Africa. Employing Bakhtin‘s theory of the carnival and other such concepts as polyphony and the grotesque, this paper examines the correlation between masculine representations, spatial re-organization and futurity as alternative ways in thinking about Africa‘s future. The result of the analysis is that the correlation between forms of communities and forms of masculinities is an indication of a vision of hope for Postcolonial Africa.

Industrial Activity Land Suitability Assessment Using Delphi and AHP to Control Land Consumption¨: The Case Study of Bordj Bouarreridj, Algeria
Authors: Benaissa F. T. , Khalfallah B.
Published: October 2021

Studies and research on land suitability for the localization of economic and industrial activities in cities are attracting academics and local policies concerned with urban planning and organization in order to make urban areas more accommodating. The current paper aims to demonstrate the ability of visualization and simulation techniques to assist planners in preserving urban real estate by combining the Delphi method with one of the multi-criteria hierarchical analysis decision-making techniques. The city of Bordj Bouarreridj in Algeria was chosen as the case study and, with the participation of experts, a set of criteria were adopted to determine land suitability. Three criteria were selected in the first phase with the use of the Delphi method. In the second phase, we applied the Analytical Hierarchy Process (AH, a hierarchical analysis method. During the third stage, the obtained results were translated into the GIS program to derive the spatial suitability map. The following are among the most important achieved results: 13.38% (521.793 km2) of the area was regarded to be of high suitability, 67.54% (2,634.758 km2), achieved moderate suitability, 12.94% (504,794 km2) attained low suitability, and 6.14% (239,685 km2) were found to be not suitable at all.
Variation Evaluation of Path Characteristic and Site Amplification Factor of Earthquake Ground Motion at Four Sites in Central Japan
Authors: Nagao T.
Published: October 2021

The considered parameters in seismic design vary, with the Earthquake Ground Motion (EGM) having the largest variation. Since source characteristic, path characteristic, and Site Amplification Factor (SAF) influence the EGM, it is crucial to appropriately consider their variations. Source characteristic variations are mainly considered in a seismic hazard analysis, which is commonly used to evaluate variations in EGM. However, it is also important to evaluate variations in path characteristic and SAF with only a few studies having individually and quantitatively examined the variations of these two characteristics. In this study, based on strong-motion observation records obtained from four sites in central Japan, the three characteristics were extracted from seismograms using the concept of spectral inversion. After removing the source characteristic, the path characteristic and SAF were separated, and the variations in these two characteristics were quantified. To separate and obtain each characteristic from the observed record, one constraint condition must be imposed, whereas the variations in the constraint condition must be ignored. In that case, the variations in the constraint condition are included in the variations of the separated characteristics. In this study, this problem was solved by evaluating the variation in the constraint condition, which is the SAF at a hard rock site, by the use of the vertical array observation record at the site.
Impact Resistance of Bendable Concrete Reinforced with Grids and Containing PVA Solution
Authors: Abd Al Kareem S. , Ahmed I. F.
Published: October 2021

The development of new building materials, able of absorbing more energy is an active research area. Engineering Cementitious Composite (ECC) is a class of super-elastic fiber-reinforced cement composites characterized by high ductility and tight crack width control. The use of bendable concrete produced from Portland Limestone Cement (PLC) may lead to an interest in new concrete mixes. Impact results of bendable concrete reinforced with steel mesh and polymer fibers will provide data for the use of this concrete in areas subject to impact loading. The experimental part consisted of compressive strength and impact resistance tests along with a result comparison with unreinforced concrete. Concrete samples, with dimensions of 100×100×100mm (cubes), and 500×500×50mm (slabs), were poured and were treated at ages of 28, 56, and 90 days. The compressive strength increased by 36.11%, 45.5%, and 52.4% respectively, whereas the impact resistance for samples reinforced with steel mesh and polypropylene fibers gave superior results to the conventional mixes.
Screen Industries in East-Central Europe
Authors: Szczepanik Petr
Published: October 2021

This book is available as open access through the Bloomsbury Open programme and is available on www.bloomsburycollections.com.

This book provides an alternative perspective into the audiovisual and media industries of eastern and central Europe, namely the Czech Republic, Poland and Hungary. In doing so, it offers insight into the ways the screen industries of small nations are positioned in and respond to globalization and digitalization. Petr Szczepanik suggests that for these ‘digital peripheries’, globalization and digitalization are as yet incomplete, stumbling processes, closely intertwined with and mediated by deeply local circumstances and players.

Instead of a top-down economic or political overview, this book places central focus on the lived realities of producers as key initiators, facilitators, and cultural intermediaries. Drawing on in-depth interviews, it looks closely at how their agency is circumscribed by the limited scale and peripheral positioning of the markets in which they operate, and how they struggle to come to terms with these constraints through their business strategies, creative thinking and professional self-perceptions.

Each of the seven chapters provides a close study of one such production practice. This includes but is not limited to independent producers limited by the size of their home markets; the ‘service producers’ working on large Western projects in Prague and Budapest and short-form online video production with its promise of dynamic growth in the era of mobile. However diverse, all these cases illustrate that while many industry practices and actors remain territorially and nationally bound, it is impossible to understand the full complexity of media markets and producer practices in the internet era without considering transcultural networks and flows. Theoretically building on the literature in critical media industry studies, this book offers a comparative analytical framework for studying small and/or peripheral media industries beyond east-central Europe.

Authors: Stepan, MD, MSc Jeffrey G. , Goodbody, MD Christine , Kumar, MD Kanupriya , DelPizzo, MD Kathryn , Fabricant, MD, MPH Peter , Wendel, MD Pamela
Published: October 2021

Objective: Guidelines for opioid prescription post-operatively exist; however, the majority of these are for adults. Nevertheless, opioid risks are present for pediatric patients also. This study investigates the effect of a single institution's guidelines on post-operative opioid prescribing for pediatric orthopedic patients undergoing knee surgery. We hypothesized that a standardized set of prescribing guidelines would result in a decrease in opioids prescribed at discharge home after these surgeries.Design: Retrospective observational.Setting: Urban, tertiary care, academic orthopedic hospital.Patients: Pediatric, sports knee surgery, 23-month period.Interventions: Guidelines were implemented institutionally for post-operative opioid prescribing practices. We reviewed all post-operative opioid prescriptions for pediatric patients undergoing sports knee surgery with two pediatric sports surgeons for the 11 months prior to the guidelines and 12 months afterwards, totaling 316 surgeries.Main outcome measure: Oral morphine equivalents (OMEs) prescribed on discharge from the hospital before and after implementation of guidelines. Results: There was a significant reduction in OMEs from 229 OMEs to 175 OMEs before and after opioid prescribing guidelines (p < 0.001). This is a decrease in approximately seven 5 mg oxycodone tablets per patient.Conclusions: This study demonstrates that at our institution, with a pediatric patient population having sports knee surgery, prescribing guidelines reduced the number of opioids prescribed at discharge.

Published: October 2021

Introduction: Sickle cell disease (SCD) is associated with recurrent complications and healthcare burden. Although SCD management guidelines differ based on age groups, little is known regarding actual utilization of preventative (hydroxyurea) and palliative therapies (opioid and nonopioid analgesics) to manage complications. This study assessed whether there were age-related differences in SCD index therapy type and SCD-related medication utilization.Design and patients: Texas Medicaid prescription claims from September 1, 2011 to August 31, 2016 were retrospectively analyzed for SCD patients aged 2-63 years who received one or more SCD-related medications (hydroxyurea, opioid, or nonopioid analgesics).Outcome measures: The primary outcomes were SCD index drug type and medication utilization: hydroxyurea adherence, and days’ supply of opioid, and nonopioid analgesics. Chi-square, analysis of variance, and Kruskal–Wallis tests were used.Results: Index therapy percentages for included patients (N = 2,339) were the following: opioids (45.7 percent), nonopioids (36.6 percent), dual therapy-opioids and nonopioids (11.2 percent), and hydroxyurea (6.5 percent), and they differed by age-groups (χ2 = 243.0, p < 0.0001). Hydroxyurea as index therapy was higher among children (2-12:9.1 percent) compared to adults (26-40:3.7 percent; 41-63:2.9 percent). Opioids as index therapy were higher among adults (18-25:48.0 percent; 26-40:54.9 percent; 41-63:65.2 percent) compared to children (2-12:36.6 percent). Mean hydroxyurea adherence was higher (p < 0.0001) for younger ages, and opioid days’ supply was higher for older ages.Conclusions: Texas Medicaid SCD patients had low hydroxyurea utilization and adherence across all age groups. Interventions to increase the use of hydroxyurea and newer preventative therapies could result in better management of SCDrelated complications and reduce the frequency of pain crises, which may reduce the need for opioid use.

Authors: Rab, BS Sayeeda , Vedula, BS Sudeepti , Merchant, MD, FACS Aziz M.
Published: October 2021

Objective: The transversus abdominis plane (TAP) block is currently being used perioperatively to reduce postoperative opioid requirements. It is unclear whether TAP blocks reduce postoperative opioid requirements for inguinal hernia repairs. The purpose of this retrospective chart study was to determine whether a TAP block reduces postoperative opioid requirements after an inguinal hernia repair in a safety net hospital.Design: This was a retrospective chart review that evaluated patients at University Hospital in Newark, NJ, who had inguinal hernia repairs from January 2011 to July 2019. Patients were divided into two groups depending on whether they had a TAP block or not. The primary outcome was the amount of opioid required in the first 24 hours postoperatively by a patient reported as morphine equivalent dosing (MED).Results: The group that received the TAP block had a mean (95 percent CI) MED of 7.01 mg (6.70, 7.33), and the control group (no TAP block) had a mean MED of 11.6 mg within 24 hours of the inguinal hernia (p = 0.03). There was no significant difference for postoperative visual analog scale (VAS) pain score, presence of nausea, or length of stay.Conclusions: Patients with TAP block required less morphine equivalence of opioid within a 24 hours period after an inguinal hernia repair.

Authors: GÜNGÖR YEŞİLOVA Pelin , YAVUZ Şeyma
Published: October 2021

This study aimed to find the depositional environment and formation conditions of the gypsum-dominated Miocene succession alternated and intercalated with clastics and carbonates in the southwestern part of the Erzincan Basin. As a result of sedimentological, mineralogical-petrographic investigations, it was determined that the gypsum in this sequence was formed as primary and secondary. Primary lithofacies; nodular anhydrite, selenitic, discoidal, gypsum arenitic secondary lithofacies; It is divided into massive, laminated, banded, nodular, brecciated, satin-spar. The facies repetitions and folds, fractures, cracks and faulting in the sequence showed the effect of tectonism with the water level fluctuations in the basin. In addition, these investigations revealed sedimentary structures such as cross-bedding, ripple undulations, chicken-wire, enterolithic and bacterial-algal structures, parallel laminations in gypsum lithofacies. In addition to these, it was understood that gypsum lithofacies were exposed to diagenetic processes under the influence of a hot-humid and semi-arid climate, organic matter activity, meteoric/underground-water and hydrothermal solution factors, and were subjected to high temperature, pressure, salinity and pH conditions.

Published: October 2021

This article explores themes resulting from a group autoethnography conducted during the COVID-19 pandemic. As participants, we are education graduate students and a professor working in both formal and informal leadership roles. We met twice a week to reflect on our present experiences implementing and leading distance education during the COVID-19 pandemic and to use these reflections to (re) imagine the future alignment of technology and education. Our self-reflexive discussions uncovered common experiential themes around educator agency, technology-induced anxiety, and leadership agency. We highlight our own growth through reflection, and we suggest important leadership qualities during times of pandemics that will raise the level of motivation and engagement of school communities and have the potential to create a stronger individual and institutional sense of agency and resiliency during a time of crisis.
Examining the Use of Wearable Technologies for K-12 Students: A Systematic Review of the Literature
Authors: Jovanovic Philip , Kay Robin
Published: October 2021

Wearable technologies such as smartwatches, smart clothing, smart glasses, fitness trackers, and brain senor headbands are wireless body sensors designed to record physiological and physical data.  Since 2015, their use has increased in K-12 classrooms, but a comprehensive investigation of student impact yet to be conducted.  In this paper, we conducted a systematic review of the literature focussing on the benefits and challenges of using wearable technologies for K-12 students.  Using the PRISMA approach and a thematic narrative analysis, we analyzed 29 peer-reviewed articles from 2003 to 2019. The benefits of using wearable technologies for K-12 students included providing students with voice, ownership of learning and reflection, increasing engagement and relevance, improving learning, building social presence, increasing accessibility, and differentiated instruction.  The challenges of using wearable technologies for K-12 students were health and safety as well as diminished perceptions of self-worth. Finally, we explored future research directions for wearable technologies in K-12 classrooms, including improved wearables-based pedagogy, data analysis methods, data ethics, and security policies.
Developing Coding Structures For Becoming Affect-Savy in the Fully Online Community Model
Authors: Yagci Ufuk , VANOOSTVEEN ROLAND
Published: October 2021

This study aims to provide support for the efficacy of the Fully Online Learning Community (FOLC) Model by examining communication between participants within a series of recorded online focus groups and by investigating the behaviours that are undertaken by participants. A coding system based on body language expressions is proposed as an outcome of this study and the affective domain of the participants is analyzed through facial expressions, body language and content (words) employed. Findings suggest that affects (emotions) have a preeminent role in the social presence in FOLC environments. Positive emotions are easier to detect as individuals exhibit them without masking, with some possible exceptions arising from personal dispositions and cultural inferences. Negative emotions can also be detected through a combination of facial expressions and body language coding. However, findings were not consistent for determining sadness and surprise states and further studies will have to explore ways to differentiate these affects from others. The instigations set forward by the participants and affective responses to the behaviours of instigators provided support for the empirical study about the efficacy of facilitation and interactions within fully online learning environments.
Resultados preliminares del Ambiente Acústico Enriquecido como terapia sonora personalizada del acúfeno
Authors: Cobo Pedro
Published: October 2021

El objetivo de este artículo es describir los fundamentos de una terapia sonora, el Ambiente Acústico Enriquecido (EAE), para la estimulación selectiva de pacientes con acúfenos. El estímulo sonoro consiste en una secuencia de tres tipos de tonos (pip, burst y gamma) de frecuencia aleatoria, dentro de la banda de frecuencias audibles, cada uno de ellos con una amplitud directamente proporcional a la pérdida de audición del sujeto a esa frecuencia. Las secuencias de tonos pip y tonos burst ya han demostrado su eficacia en la restauración del mapa tonotópico de animales expuestos previamente a un ruido traumatizante, y  en el restablecimiento la hipersensibilidad de un grupo de pacientes con hiperacusia, respectivamente. Las secuencias de tonos gamma, cuyos fundamentos se describen en este artículo, constituyen una propuesta original. La sucesión de tonos resultante estimula secuencialmente el sistema auditivo del sujeto compensando su pérdida de audición, que es una de las causas que disparan el acúfeno.

This research is aimed to describe the communication patterns of the Presidential Palace journalists when they want to get and write news. The journalists who were assigned in Predidential Palace must come from different media. There were dozens of journalists from various media who were assigned in the Presidential Palace. However, the Presidential Palace journalists had been seen as prestigious because they were assigned in important posts. This research used a constructivist paradigm approach. The dats collection was carried out by observing and interviewing the journalists in the field. In writing news, the Presidential Palace journalists were also bounded by the agreement between the journalists from various media who are assigned to the Presidential Palace. The results showed that Presidential Palace journalists shared news with each other and established communication, so that everyone could get news. Among the Presidential Palace journalists, sharing the results of interviews was common. This condition made the news that appeared in various media, especially online, to be almost the same, even though the angle chosen is different. They also did not know the practice of breaking into or looking for exclusive news, because if that happened, the access to information could be closed.

This study aims to determine the communication accommodation strategy in the online learning process during the Covid-19 pandemic which occurred in teaching and learning activities in English at the elementary, junior high, senior high school and vocational school levels in Jakarta and also to determine the obstacles in communication accommodation strategies in the learning process. This study uses an exploratory method with Communication Accommodation Theory as a reference for data analysis used to discuss the possibility of a new phenomenon that has not been found in previous research and to examine phenomena in the context of real life. The results showed that the convergence strategy in communication accommodation in the online learning process during the Covid-19 pandemic was mostly carried out by English teachers at the SD, SMP, SMA, and SMK levels. This is to show that the teaching and learning delivery process is easier for students to understand and accept during online learning. In addition, based on the results of the interview, the researcher found that there were obstacles and impacts that were felt in the teaching and learning process taking place. Students tend to be passive compared to face-to-face learning.

Health communication is a systematic effort that has a positive impact on the health practice of a large population. The Covid-19 pandemic, which is felt quite suddenly, caused confusion from all sectors, one of which is the health sector. The health sector in Indonesia looks unprepared for this pandemic in communicating the Covid-19 virus to the public. Therefore, health communication, which is part of mass communication, is one of the communication models that can give information the public about health. The focus in this research is on health communication strategies during the COVID-19 pandemic. The research method used in this research is literature study. The result and conclusion of this study which is the health communication strategy in building public participation during the covid-19 pandemic is 1) health communication campaigns must be carried out in an integrated and sustainable manner and carried out by experts, 2) creating and implementing appropriate and effective communication strategies in handling Covid-19, 3) developing appropriate, effective and efficient tactics and technical actions and procedures
Erityisopetus ja oppivelvollisuus
Authors: Jahnukainen Markku
Published: October 2021

Vaikka yleinen oppivelvollisuus säädettiin vuoden 1921 oppivelvollisuuslailla koko ikäluokkaa koskevaksi, moni poikkeavaksi katsottu oppilas jäi vielä pitkään parhaimmillaankin joko erityiskoulu- tai laitossijoitukseen ellei sitten kokonaan opetuksen ulkopuolelle (Tuunainen 2002). Sittemmin tukea tarvitsevien oppilaiden asemaa oppivelvollisuuden suorittamisen suhteen on kohennettu asteittain ja viimeisenä ryhmänä yhtenäiskoulun piiriin siirtyivät vaikeimmin kehitysvammaiset oppilaat syksyllä 1997 (Jahnukainen & Korhonen 2003). Oppivelvollisuuden ja samalla tuen kestolla on erityisopetuksen kannalta ollut merkittävä funktio: osa vammaisoppilaista opiskelee pidennetyn, eli vuotta aiemmin alkavan ja vuoden pidempään kestävän 11-vuotisen oppivelvollisuuden mukaisesti. Päätökset oppivelvollisuuden pituudesta tehdään yksilöllisesti. Oppivelvollisuuden pituuden säätely, samoin kuin oppimäärien yksilöllistäminen (Jahnukainen ym. 2020), ovat siis olleet osana eriyttämisen keinovalikoimaa. Yleisellä tasolla kuitenkin suomalainen perusopetusjärjestelmä on toimintamalliltaan varsin yhtenäinen ja reittien jakautuminen alkaakin nykyisellään siirtymässä oppivelvollisuuskoulusta toiselle asteelle (Jahnukainen ym. 2018). Oppivelvollisuusiän korottaminen ja oppivelvollisuuden laajentaminen on ollut pitkän linjan poliittinen hanke, joka nykyisellä Sanna Marinin hallituskaudella on muodostunut keskeiseksi koulutuspoliittiseksi hankkeeksi ja jossa tukea tarvitsevilla oppilailla on ollut keskeinen rooli.

Abstract. Cold surge (CS) is considered a favorable weather process to improve air quality and is widely recognized. However, there is no detailed study on the differences in the dispersion ability of different types of CSs in relation to haze days in eastern China (HDEC). This paper uses the hierarchical clustering algorithm to classify the cool-season (November to February of the following year) CSs across eastern China into blocking CSs and
wave-train CSs and compares their influences on the number of HDEC from
1980 to 2017. Results show that the wave-train CSs can significantly improve
the visibility in eastern China and generally improve air quality for about
2 d longer than the blocking CSs, which indicates that the blocking CSs
have a weaker ability to dissipate HDEC compared with the wave-train
CSs. The CSs affect the HDEC by changing meteorological elements like
thermal inversion potential, horizontal surface wind, sea level pressure
(SLP), and surface air temperature (SAT). A period of 4 d after the outbreak of CSs, the
variations of thermal inversion potential and horizontal surface wind of two
types of CSs tend to be consistent. However, the negative SAT anomalies and
the positive SLP anomalies caused by the blocking CSs lasted shorter than
those caused by the wave-train CSs, forming favorable conditions for the
rapid growth of HDEC. Furthermore, results show that in recent years,
especially after the 1990s, the frequency of wave-train CSs has decreased
significantly, while the frequency of blocking CSs has slightly increased,
indicating that the overall ability of CSs to dissipate HDEC has
weakened in general. This work may provide reference for the future
formulation of haze control policies in East Asia.

Abstract. Atmospheric mercury speciation is of paramount importance
for understanding the behavior of mercury once it is emitted into the
atmosphere as gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and
particulate-bound mercury (PBM). GOM and PBM can also be formed in the
atmosphere; their sampling is the most problematic step in the atmospheric
mercury speciation. GOM sampling with speciation traps composed of KCl
sorbent materials and KCl trapping solutions are commonly used sampling
methods, although the research conducted with them at ambient air
concentrations is limited. The results of the specificity test demonstrated
that the KCl sorbent traps are highly specific when using new traps, while
their specificity drops dramatically when they are reused. The results of
the stability test indicated that the highest Hg2+ losses (up to
5.5 % of Hg2+ loss) occur when low amounts of Hg2+ (< 1 ng) are loaded, due to a reduction of Hg2+ to Hg0. KCl trapping solutions have also been considered as a selective trapping media for GOM in atmospheric samples. A dimensionless Henry law constant was experimentally
derived and was used to calculate the solubility of elemental Hg in KCl
solution. The degree of GEM oxidation was established by purging elemental
Hg calibration gas into a KCl solution and determining the GOM trapped using
aqueous-phase propylation liquid–liquid extraction and gas chromatography–atomic fluorescence spectrometry (GC-AFS) measurement. A positive GOM
bias was observed due to the solubility and oxidation of GEM in KCl trapping
solutions, strongly suggesting that this approach is unsuitable for
atmospheric mercury speciation measurements.

Abstract. The COVID-19 (COronaVIrus Disease 2019) pandemic provided the unique opportunity to evaluate the role of a sudden and deep decline in air pollutant emissions in the ambient air of numerous cities worldwide. Argentina, in general, and the Metropolitan Area of Buenos Aires (MABA), in particular, were under strict control measures from March to May 2020. Private vehicle restrictions were intense, and primary pollutant concentrations decreased substantially. To quantify the changes in CO, NO, NO2, PM10, SO2 and O3 concentrations under the stay-at-home orders imposed against COVID-19, we compared the observations during the different lockdown phases with both observations during the same period in 2019 and concentrations that would have occurred under a business-as-usual (BAU) scenario under no restrictions. We employed a Random Forest (RF) algorithm to estimate the BAU concentration levels. This approach exhibited a high predictive performance based on only a handful of available indicators (meteorological variables, air quality concentrations and emission temporal variations) at a low computational cost. Results during testing showed that the model captured the observed daily variations and the diurnal cycles of these pollutants with a normalized mean bias (NMB) of less than 11 % and Pearson correlation coefficients of the diurnal variations of between 0.65 and 0.89 for all the pollutants considered. Based on the Random Forest results, we estimated that the lockdown implied concentration decreases of up to 47 % (CO), 60 % (NOx) and 36 % (PM10) during the strictest mobility restrictions. Higher O3 concentrations (up to 87 %) were also observed, which is consistent with the response in a VOC-limited chemical regime to the decline in NOx emissions. Relative changes with respect to the 2019 observations were consistent with those estimated with the Random Forest model, but indicated that larger decreases in primary pollutants and lower increases in O3 would have occurred. This points out to the need of accounting not only for the differences in emissions, but also in meteorological variables to evaluate the lockdown effects on air quality. The findings of this study may be valuable for formulating emission control strategies that do not disregard their implication on secondary pollutants.
