Authors:   Junior Researcher, Institute of Immunology and human genomics of the Academy of Science of the Repulic of Uzbekistan,, Ruzimurodov Nodir Fazliddinovich
Published: November 2021

New Coronavirus Infection (COVID-19) is a novel zooanthroponous respiratory infection caused by the Sars-Cov-2 coronavirus. The virus was first identified during an epidemic outbreak in Wuhan City, Hubei Province, China, which has been reported since December 11, 2019. Since then, scientists have been studying the characteristics of the virus to determine the severity of the disease. For a complete and reliable assessment of the severity of the disease in this pathology, the cytokine status was studied and investigated integral characteristics of the clinical and immunological prognosis of the severity of COVID-19 in the population of Uzbekistan.

Published: November 2021

Pulmonary embolism is a fatal condition leading to loss of life if delay in treatment and diagnosis is present. Every year many patients present to tertiary centre with features suggestive of pulmonary embolism and a large proportion belong to postpartum pulmonary embolism. Due to the hyper coagulable state during pregnancy, pregnant and postpartum females are more prone to pulmonary embolism. Methods: All the patients records who were diagnosed as pulmonary embolism admitted in Manmohan Cardiothoracic Vascular and Transplant Center between Baisakh 2070 to Poush 2077 were investigated and observational cross-sectional study of patient population on the basis of demography, parity, day of diagnosis of postpartum Pulmonary embolism and modes of delivery was done.

Investigation of Benford’s Law with YouTube Social Media Statistics
Authors: Chen Chi-Wei , Yu Shao-Yu , Chen Hsin-Yi
Published: November 2021

In this study, we used social media data to investigate Benford’s Law. In our experimental analysis, we used three control variables: Total Subscriptions, Total Views, and Video Uploads of Youtube channels to verify if the data is artificial and whether or not it fits Benford’s Law. We noticed how Total Subscriptions does not fit Benford’s Law for the top 5000 most-subscribed channels, and Total Views doesn’t fit for the top 5000 most-viewed channels. The reasons that cause this difference are further investigated in this paper. We also proposed a mathematical model to verify if other datasets fit Benford’s Law. After curve fitting the experimental data, results revealed that closer a and b values in our mathematical model indicate that a dataset fits Benford’s Law.
How is economic growth correlated to index growth?
Authors: Chordia Aryan , Gurbani Karan
Published: November 2021

This study will mainly focus on the relation between GDP growth and stock market index growth through various methods like the Pearson product-moment coefficient correlation, comparing the theoretical world to the real-world situation, and finally by looking at consumer sentiments and confidence. This could help various analysts, economists, and even the general public. Through the course of our study, we find out various trends in this study, at some point, the results were contradicting themselves but then our last test made it all clear, which proves that there is no correlation between GDP growth and stock market index growth, but then both of them drives from consumer confidence and consumers future actions.
Demonstrating Tangential Velocity by a Self-Coded Robot
Authors: Hwang Pete , Tadeo Danilo JR
Published: November 2021

Tangential velocity is a concept that is often taught as a part of rotation, and is the linear velocity an object has as it turns about a fixed axis. The main goal of this research project was to examine this concept and demonstrate it on a self-coded robot. The robot was designed with two rotating motors with two wings of different lengths to be attached on top, and the motors were connected to a circuit board and coded using the programming language C to rotate with equal and constant angular velocities upon initiation. The main hypothesis is that the length of rotating wings is directly proportional to the tangential velocity of the wings. The project provides a new way of demonstrating tangential velocity in a high school physics class.
Connectivity of the Superior Longitudinal Fasciculus II and Executive Function in Children with ADHD
Authors: Ma Larissa , Joykutty Leya , Dick Anthony
Published: November 2021

Attention-deficit hyperactivity disorder (ADHD) is a common childhood neurodevelopmental disorder marked by inattention, hyperactivity, and impulsiveness. The importance of the Superior Longitudinal Fasciculus II (SLFII), a white matter tract connecting the frontal and parietal regions, to developing executive function has not been established in children who typically have executive function deficits. The present study explored the association between diffusion properties of the SLFII and developing executive function in young children diagnosed with ADHD. A dataset with the performance on the NIH Toolbox Card Sort and the NIH Toolbox Flanker, two executive function tasks, in 59 4-7-year-old children was used, and diffusion-weighted magnetic resonance imaging scans were used to quantify the white matter properties of the bilateral SLFII. The results showed that there was an association between age and performance on the Flanker and Card Sort tasks. As age increased, performance also improved. There was no significant association between white matter properties of the SLFII, birth sex, and the Card Sort and Flanker tasks. As the first study to explore this association in children of this age with ADHD, this result was unexpected suggesting that it may be the case that it is too early in development to detect a strong association. The findings inform contemporary and future investigations into the brain-behavior relations between SLFII and executive function in children with ADHD. With further research, neuroimaging could become a potential diagnostic biomarker for predicting executive function impairments and ADHD symptoms in young children, potentially altering treatment outcomes.
Mesenchymal Stromal Cells Used for Cellular Cardiomyoplasty As a Way To Treat Myocardial Infarction and Heart Failure
Authors: Okpala Amarachukwu , Joykutty Leya
Published: November 2021

Heart disease is one of the leading causes of morbidity and mortality worldwide. Two of these diseases are heart failure and myocardial infarction. In America alone, there are about 6.2 million people with heart failure, and every 40 seconds, a patient with a heart attack is recorded. Myocardial infarction, known as a heart attack, occurs after the blocking or occlusion of a coronary artery, disabling the delivery of oxygenated blood to regions of the heart. Heart failure, usually occurring after ischemic diseases like myocardial infarction, is where the heart loses the ability to pump a sufficient blood supply to meet the body’s needs. The major ways of treating heart failure and myocardial infarction today are either too expensive or hard to come by, so a new sort of treatment is direly needed. Cellular cardiomyoplasty, a form of cell therapy, is being looked into as a new way to treat these two and other cardiomyopathies. Additionally, though there have been a few cells that have shown a possibility of use for cardiomyoplasty, this review focuses on mesenchymal stem cells, specifically called mesenchymal stromal cells. The purpose of this review is to look into what cellular cardiomyoplasty is, how it may be used in the future, and how mesenchymal stromal cells have shown potential to be used for it.
Tectonic setting of kimberlites in the Vilyui-Markhinsky fault zone according to modern data
Authors: Protsenko Elena , Shakhurdina Nadezhda
Published: November 2021

The lateral heterogeneity of the Vilyui-Markha fault zone was determined, the central and western subzones were identified. The high-grade diamondiferous Mir and Nakyn kimberlite fields are confined to the central subzone. The low-grade diamondiferous Syuldyukar kimberlite field is confined to the western subzone of the VilyuiMarkha zone. The analysis of the fault network density in the research area was carried out. It was found that the fault network density increases within the subzones, which characterizes them as increased permeability areas favorable for kimberlite melts uprising. This fact can be another tectonic criterion for setting up diamond prospecting operations.
Ratio of structural impurity distribution in diamond crystals and kimberlite pipe diamond potentiak (case study of Arkhangelsk region and Yakutia)
Authors: Khachatryan Galina , Anashkina Nataliya
Published: November 2021

IR spectroscopy was used to compare diamonds from 12 pipes, Arkhangelsk region. Based on positive correlation between average N and H values in diamonds from various deposits, it was found that crystals from low-grade diamond pipes are relatively enriched in hydrogen compared with diamonds from Lomonosov and Grib deposits. In terms of structural impurity distribution, Arkhangelsk deposit diamonds differ from Yakutian diamonds; it could be due to various composition of compared diamonds’ source matter and thermodynamic conditions of their growth. It is shown that hydrogen is a negative factor of diamond potential in both Yakutian and Arkhangelsk diamonds. This can partly be explained by impuri-ty blocking effect on diamond crystal growth.
Unpacking Africa as a dynamic continent: Insights from contemporary development issues in Ghana
Authors: Oteng-Ababio Martin
Published: November 2021

Since the last formal vestiges of colonial rule disappeared in 1994, the democratically elected governments on the African continent have been experimenting with developmental strategies and policies. These experiments come at the backdrop that Africa’s output per head is notoriously among the lowest in the world and has, on the average, expanded slowly and haltingly since 1960, albeit, with some critical changes, and variations over place, space and time. The structural adjustment programme (SAP) in the 1980s, for example, marked a watershed: a fundamental shift from administrative to market means of resource allocation. This opinion piece, appearing in this Special Issue of the Oguaa Journal of Social Sciences on the theme “Developmental issues in contemporary Ghana”, provides an overview of Africa’s development trajectories as presented by the collection of articles, using Ghana as a test-tube.

Authors: Damisa John , Emegha Joseph Onyeka
Published: November 2021

The effects of deposition cycles on the structural and optical properties of lead tin sulphide (PbSnS) thin films have been described. Successive ionic layer adsorption and reaction (SILAR) method was used to deposit the ternary material on soda-lime substrates. In the present work, the PbSnS films were grown using lead nitrate, tin chloride dehydrate and thioacetamide solutions as sources of Pb, Sn and S, respectively. XRD measurements revealed that the deposited films were polycrystalline in nature with strong adherent to the substrates. The transmittance was found to be high in the near infrared regions of the electromagnetic radiation and, also increased with deposition cycles. The band gap energy was found to vary from 1.70 to 1.75 eV for 10 and 35 deposition cycles. The study indicates that SILAR is an excellent method in depositing good quality films for device applications.
HIGHLIGHTS

SILAR is an excellent technique for depositing thin films of lead tin sulphide (PbSnS)
Deposition cycles influences the XRD and optical properties of PbSnS thin films
PbSnS thin films are useful for solar cell fabrications
The band gaps of the PbSnS varies from 1.70 to 1.75 eV with deposition cycles

Degradation of Poly(Butylene Succinate) and Poly(Butylene Succinate)/Poly(Lactide) Blends using Serine Protease Produced from Laceyella sacchari LP175
Authors: Samaimai Srisuda , Krajangsang Sukhumaporn , Kitpreechavanich Vichien , Borthong Jednipit , Lomthong Thanasak
Published: November 2021

The thermophilic filamentous bacterium Laceyella sacchari LP175 was cultivated in a 10.0 L airlift fermenter to produce serine protease at 50 °C. Maximal serine protease activity at 1,123.32 ± 15.8 U/mL was obtained for cultivation at 0.6 vvm aeration rate for 36 h. The crude enzyme was applied for degradation of poly (butylene succinate) (PBS), and poly (butylene succinate)/poly(lactide) blend (PBS/PLA) powders at 50 °C for 48 h with different substrates and enzyme concentrations. Results showed that serine protease produced from L. sacchari LP175 degraded PBS and PBS/PLA at 46.5 ± 2.05 and 49.8 ± 1.45 %, respectively, at an initial substrate concentration of 100 g/L with 1,200 U/mL of serine protease activity. Percentage degradation of PBS and PBS/PLA was improved to 51.4 ± 1.06 and 56.9 ± 1.42 %, respectively, when upscaled in a 2.0 L stirrer fermenter with 200 rpm agitation rate. Degradation products evaluated by a scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) confirmed that serine protease produced from L. sacchari LP175 degraded both PBS and PBS/PLA polymers. Results showed that microbial enzyme technology could be used to degrade PBS and PBS/PLA blend polymers and reduce the accumulation of waste.
HIGHLIGHTS

Upscaled serine protease production was achieved in a 10 L airlift fermenter by sacchari LP175 using low-cost agricultural products as substrate
The crude enzyme degraded PBS and PBS/PLA powders (100 g/L) at up to 51.4 and 56.9 %, respectively in a 2.0 L stirrer fermenter under optimal conditions
Degradation products of PBS and PBS/PLA by crude enzyme produced from sacchari LP175 were characterized

GRAPHICAL ABSTRACT
Historical and Cultural Contexts in India
Authors: Mallick Krishna
Published: November 2021

This chapter explores the historical background of British rule in India
(1757-1947) and the different Forest Acts that were imposed by the colonial
authorities that infringed the rights of the people. This eventually led to
protests against the forest management, most of which were suppressed
by the British government. Community forest management councils (van
panchayat) were formed to protect the inhabitants but then the British
classified most of the forest as reserve forests, centralizing their control
over the forest and displacing the people. Gandhi’s method of nonviolence,
satyagraha, is analyzed by showing how Gandhi was influenced by the
Gita, Tolstoy, Ruskin, and Thoreau and how Gandhian views have been
followed in the Chipko, NBA, and Navdanya movements.
The Re-Invention of Rome in the Early Middle Ages
Authors: Osborne John
Published: November 2021

The history of Rome in the early Middle Ages is best understood as a
continuous evolution from Rome of the Caesars to Rome of the popes,
with the latter taking on many of the roles of their imperial predecessors.
A critical moment occurs in the seventh and early eighth centuries, when
the physical ‘landscape’ of the city is ‘re-invented’, essentially transformed
from pagan to Christian through an appropriation of the material vestiges
of the ancient city, as well as aspects of ritual behavior such as the development
of the stational liturgy. This landscape was imbued with memories
and meaning, transmitters of the city’s identity and history; and these
understandings were ‘Christianized’, fulfilling the city’s manifest destiny.
Rewriting the Renouveau
Authors: Kinney Dale
Published: November 2021

The art and architecture of eleventh-century Rome are predominantly
discussed within the framework of an ‘early Christian renewal’ (renouveau
paléochrétien) closely tied to the Gregorian Reform. Articulated fifty years
ago in accordance with the prevailing top-down model of history, the
framework is incompatible with more recent historical approaches that
emphasize agency from below. This essay argues for a more distributed
model of agency in the making of eleventh-century art. A case study of
Santa Maria in Trastevere, reformed in 1065, calls into question the model
of a Reform art directed by cardinals. A comparison with cinematic auteur
theory questions the concept of a Reformist ‘directed art’ from another
perspective.
Woman with a Shell: Transcultural Exchange, Female Bodies and Maritime Matters
Authors: Grasskamp Anna
Published: November 2021

This chapter discusses images of women with shells across Eurasia and the artistic
negotiation of materiality and corporality, objectification and sexual agency,
intimacy and distance in both physical and geographical senses. While some of the
works discussed are well-known representations of Venus surrounded by sexualised
objectscapes, the chapter also introduces religious imagery framed by shells and
women with shells in early modern Chinese and Japanese paintings. Despite their
differences, all of these works link female bodies to objects of maritime material
culture. The chapter argues that in China and Europe, images of women with
shells are visual and material reflections of foreign (underwater) spaces full of
riches, paradise-like realms that not only promise material affluence but also
erotic fulfilment.
Collective Memory and Unremembering
Authors: Doolan Paul M.M.
Published: November 2021

Maurice Halbwachs demonstrated that memory is shaped by social forces.
I argue that collective memory is mediated in symbolic representations.
National collective memory is unstable and open to revision and is a site
for dispute between alternative representations. Changes in media lead
to changes in collective memory. The trauma within collective memory
is passed down through generations. I argue that collective memory
is not a process of remembering and forgetting, but remembering and
unremembering. Unremembering is a process of concealment. Literature
is significant in shaping collective memory, but so too are film, memoir,
public media like newspapers and television, as well as works of historical
scholarship. I end this chapter with a factual summary of the Indonesian
War of Independence.
Post-decolonization: The First 20 Years, 1949-1969
Authors: Doolan Paul M.M.
Published: November 2021

While the German occupation of Holland came to dominate post-war
Dutch collective memory, the memories of those repatriated from Indonesia
suffered from a loss of place. This caused a traumatic rupture in
remembering. During the 1950s and early 1960s, nostalgic remembering
in the works of the likes of Dermoût and Nieuwenhuys, as well as feelings
of existential angst and victimhood, contributed to unremembering the
reality of decolonization. However, memories of military brutality were
present in the stories of Beb Vuyk and in the memoirs and novels of some
veterans. Unlike American and Australian historians, few Dutch historians
showed much interest in decolonization. Despite some promising historical
work in the early 1950s, historians and memoirists ignored the reality of
warfare.
Loe de Jong Controversy
Authors: Doolan Paul M.M.
Published: November 2021

During the 1970s and 1980s Dutch historians of colonialism continued
to produce works on the war of decolonization that failed to provide
any sustained analysis of actual fighting, creating the impression that
the war was fought exclusively by diplomatic means. The work of Jan
Bank formed a modest exception. This silence of Dutch historians can
be understood by using the metaphor of the guild. The historical guild
reinforced and rewarded the virtues of avoiding controversy, speculation
and sweeping statements. This systemic unremembering was broken by
the work of IJzereef in 1984 and especially by Loe de Jong in the late 1980s.
De Jong was forced to endure vehement criticism and legal proceedings.
But unremembering was at last being publically contested.
Introduction
Authors: Doolan Paul M.M.
Published: November 2021

In this introduction, I explain how, during five years of studying history in
the Netherlands in the mid-1980s, it puzzled me that we never studied the
decolonization of the Dutch East Indies. The subject was reported in the
news, but indifference seemed to dominate within the university. This has
led me to the question, How has the decolonization of the former Dutch
East Indies during the period from 1945 to 1949 been represented in Dutch
culture? My aim is to map out the process by which a collective memory
of the war of decolonization was constructed among the Dutch during the
50 years after the declaration of independence in Indonesia (1945-1995).
Using a variety of theoretical frames, I apply new readings to memories of
decolonization that have been mediated in literature, memoirs, historical
works, journalism, radio and television documentaries and film. This will
reveal the means by which decolonization came to be (un)remembered.
LEVANTAMENTO DE NINHOS DE ABELHAS “SEM FERRÃO” (APIDAE: MELIPONINI) EM AMBIENTE URBANO
Authors: Mangabeira Tatiannie Caldas Lima , Almeida Lidiane Santos , Santos Ana Paula Lima Do Couto
Published: November 2021

Introdução: As abelhas nativas “sem ferrão”, são assim chamadas por terem o ferrão atrofiado, vestigial. Conhecidas como meliponídeos, possuem hábitos diurnos, com sua colônia formada por rainha, princesas, operárias e zangões. Apresentam grande importância para a natureza como agentes polinizadores, promovendo a manutenção da biodiversidade. São insetos que nidificam principalmente em ocos de árvores, fendas de rochas, ninhos abandonados, por cupins ou formigas e podem fazer ninhos aéreos. Com a urbanização começaram a buscar locais na cidade para nidificar, utilizando de muros, paredes de casas, postes e solos para construção de seus ninhos. Objetivo: O objetivo desse estudo é realizar um levantamento dos ninhos naturais de abelhas encontradas no ambiente urbano da cidade de Itapetinga, na Bahia. Material e métodos: O trabalho foi realizado através de caminhadas aleatórias, ao longo de 20 bairros na cidade, correspondendo a 67% do total, de junho a agosto de 2021. Realizado pelo período da manhã, com temperaturas em torno de 21 °C, das 08 às 12 horas, dando preferência às praças e locais próximos à jardins domiciliares. Estes ambientes foram escolhidos por apresentar maiores ofertas de recursos e assim maior probabilidade de nidificação nas proximidades. Resultados: Foram encontrados 5 ninhos de abelhas, do gênero Tetragonisca, identificação possibilitada pela entrada característica do ninho. O 1° estava em uma árvore com tronco oco; o 2° em uma fenda na parede ao lado de uma goiabeira Psidium guajava L.; o 3° em uma fenda em uma parede de tijolo, próximo ao chão; o 4° em uma cavidade dentro de um poste; e o 5° em uma planta arbustiva, Cycas L. spp. A distribuição ficou restrita a dois bairros da cidade. Ambos apresentavam proximidade com pequenas praças e jardins domiciliares, com espécies de plantas variadas, principalmente frutíferas, que influenciaram positivamente na sobrevivência das abelhas. Conclusão: Os resultados deste estudo contribuem para o conhecimento das espécies de abelhas, promoção de práticas para ampliação das áreas com flora apícola, e incentivo para a conservação das abelhas “sem ferrão” em ambientes urbanos.

A ambiguidade em “Famigerado” e o lógos como senhor poderoso
Authors: Santana Juliana , Penedo do Amaral Roberto Antônio
Published: November 2021

O artigo tem o objetivo de verificar a possibilidade de estabelecer um diálogo entre os discursos apresentados no conto “Famigerado”, do escritor mineiro João Guimarães Rosa, e a perspectiva de Górgias de Leontini sobre o lógos, conforme o apresenta no Elogio de Helena. Para alcançar o objetivo proposto pelo estudo, iniciamos com a indicação das ambiguidades presentes no conto de Guimarães Rosa. Em seguida, essas indicações nos permitiram perceber as ambiguidades presentes igualmente na teoria exposta no Elogio de Helena, tomando lógos ora como discurso, ora como palavra, sempre na condição de um senhor poderoso. Essa constatação nos levou ao último movimento do estudo, no qual pudemos associar as perspectivas sobre os lógoi propostas por Górgias e aquelas do discurso e das palavras que compõem a trama do conto rosiano em apreço. Deste modo, o desenvolvimento da discussão por nós proposta ao longo deste artigo aponta para afirmativamente a possibilidade de diálogo entre os textos estudados, pois tanto a configuração de “Famigerado” quanto a do Elogio de Helena e dos testemunhos sobre o pensamento de Górgias permitem estabelecer o lógos como um senhor poderoso.
A distinção entre pensamento calculador e pensamento meditativo na filosofia tardia de Martin Heidegger
Authors: Siqueira Ana Carla de Abreu
Published: November 2021

Este artigo pretende elucidar dois conceitos fundamentais na filosofia tardia de Martin Heidegger: o pensamento calculador e o pensamento meditativo. Em um primeiro momento, apresentamos o pensamento calculador, o qual é bastante comum na época moderna através do domínio do sujeito e da técnica. Em seguida, apresentamos o pensamento meditativo e sua proximidade à questão do ser. A meditação se abstém do controle do mundo e precisa ser cultivada como uma habilidade do ser humano. A distinção entre pensamento calculador e pensamento meditativo diz respeito ao pensamento humano e às ações humanas, como vemos na era atual.
Da vulnerabilidade da Filosofia: um estudo sobre a presença da filosofia como uma disciplina frente às atuais mudanças curriculares no ensino médio
Authors: Ramalho Ellen Maianne Santos Melo
Published: November 2021

A presença da Filosofia enquanto disciplina escolar no currículo do ensino médio no Brasil, passa por um novo momento histórico. Marcado principalmente por novas legislações educacionais, como a Lei 13.415/17 e a aprovação da Base Nacional Comum Curricular - BNCC, a política educacional brasileira modificou-se substancialmente e ameaça a não permanência da Filosofia no currículo do ensino médio. Desta forma, a partir desse novo contexto político educacional, urge a necessidade de se discutir a presença da Filosofia nas escolas de ensino médio no Brasil, ressaltando mais uma vez, a sua importância. Para tanto, esse trabalho se propõe a responder a problemática:  Por que a Filosofia se torna vulnerável dentro do atual contexto político educacional brasileiro? A partir dessa problemática pretendemos corresponder aos seguintes objetivos: Discutir qual o lugar da Filosofia após as mudanças na legislação educacional brasileira; abordar os fatores responsáveis pelo caráter de vulnerabilidade da filosofia e ressaltar o importante papel formativo da Filosofia na educação.  Trabalhar a temática do novo ensino médio é bastante relevante, uma vez que o novo ensino médio irá impactar diretamente na vida de milhões de brasileiros e brasileiras.
A filosofia política de Tomás de Aquino: a natureza humana como centro da argumentação
Authors: Ezídio Camila
Published: November 2021

O propósito geral deste artigo é tratar do conceito de natureza humana posta na qualidade de figura central da argumentação política de Tomás de Aquino.

O ambiente educacional promove o desenvolvimento social, experiências múltiplas e a aquisição de conhecimento, entre outros, mas tal espaço exige concentração, esforço, planejamento, controle dos impulsos. Um portador do Transtorno de Déficit de Atenção (TDAH), entretanto, apresenta dificuldades nestas funções, comprometendo seu desempenho escolar e social. O objetivo geral deste trabalho é ressaltar a importância do papel e do compromisso do professor no ato de reconhecer e lidar com o TDAH. Os objetivos específicos foram definidos da seguinte maneira: Explicar o que é o transtorno de déficit de atenção; apresentar as características e o diagnóstico do TDAH; falar sobre o tratamento e discorrer sobre as causas do TDAH. Desta forma, o presente trabalho surgiu de uma inquietação pessoal observada durante minha atuação como professora há treze anos e tem como objetivo norteador verificar se a equipe pedagógica está realmente preparada para reconhecer e lidar com o TDAH, visto que o professor deve ser um dos responsáveis pela escola inclusiva e pelo desenvolvimento intelectual do discente. A metodologia utilizada foi a pesquisa descritiva com a aplicação de um questionário conjuntamente com a revisão da pesquisa bibliográfica que envolveu livros, artigos e sites. Ao longo deste trabalho, a cada descoberta proporcionada pela pesquisa, foram propostas medidas que favoreçam um melhor desempenho profissional do professor e, principalmente, a evolução escolar e social do aluno afetado por este transtorno, tais propostas, advindas das descobertas deste artigo, contribuem, diretamente, com o favorecimento da aprendizagem dos educandos que convivem com a TDAH.
Canadian and Alaskan wildfire smoke particle properties, their evolution, and controlling factors, from satellite observations

Abstract. The optical and chemical properties of biomass burning (BB) smoke particles greatly affect the impact wildfires have on climate and air quality. Previous work has demonstrated some links between smoke properties and factors such as fuel type and meteorology. However, the factors controlling BB particle speciation at emission are not adequately understood, nor are those driving particle aging during atmospheric transport. As such, modeling wildfire smoke impacts on climate and air quality remains challenging. The potential to provide robust, statistical characterizations of BB particles based on ecosystem type and ambient environmental conditions with remote sensing data is investigated here. Space-based Multi-angle Imaging Spectrometer (MISR) observations, combined with the MISR Research Aerosol (RA) algorithm and the MISR Interactive Explorer (MINX) tool, are used to retrieve smoke plume aerosol optical depth (AOD), and to provide constraints on plume vertical extent, smoke age, and particle size, shape, and light-absorption properties, and absorption spectral dependence. These tools are applied to numerous wildfire plumes in Canada and Alaska, across a range of conditions, to create a regional inventory of BB particle-type temporal and spatial distribution. We then statistically compare these results with satellite measurements of fire radiative power (FRP) and land cover characteristics, as well as short-term climate, meteorological, and drought information from MERRA-2 reanalysis and the North American Drought Monitor. We find statistically significant differences in the retrieved smoke properties based on land cover type, with fires in forests producing the thickest plumes containing the largest, brightest particles, and fires in savannas and grasslands exhibiting the opposite. Additionally, the inferred dominant aging mechanisms and the timescales over which they occur vary systematically between land types. This work demonstrates the potential of remote sensing to constrain BB particle properties and the mechanisms governing their evolution over entire ecosystems. It also begins to realize this potential, as a means of improving regional and global climate and air quality modeling in a rapidly changing world.

Abstract. TROPOMI measurements of tropospheric NO2 columns provide powerful information on emissions of air pollution by ships on open sea. This information is potentially useful for authorities to help determine the (non-)compliance of ships with increasingly stringent NOx emission regulations. We find that the information quality is improved further by recent upgrades in the TROPOMI cloud retrieval and an optimal data selection. We show that the superior spatial resolution of TROPOMI allows the detection of several lanes of NO2 pollution ranging from the Aegean Sea near Greece to the Skagerrak in Scandinavia, which have not been detected with other satellite instruments before. Additionally, we demonstrate that under conditions of sun glint TROPOMI's vertical sensitivity to NO2 in the marine boundary layer increases by up to 60 %. The benefits of sun glint are most prominent under clear-sky situations when sea surface winds are low, but slightly above zero (±2 m/s). Beyond spatial resolution and sun glint, we examine for the first time the impact of the recently improved cloud algorithm on the TROPOMI NO2 retrieval quality, both over sea and over land. We find that the new FRESCO+wide algorithm leads to 50 hPa lower cloud pressures, correcting a known high bias, and produces 1–4·1015 molec/cm2 higher retrieved NO2 columns, thereby at least partially correcting for the previously reported low bias in the TROPOMI NO2 product. By training an artificial neural network on the 4 available periods with standard and FRESCO+wide test-retrievals, we develop a historic, consistent TROPOMI NO2 data set spanning the years 2019 and 2020. This improved data set shows stronger (35–75 %) and sharper (10–35 %) shipping NO2 signals compared to co-sampled measurements from OMI. We apply our improved data set to investigate the impact of the COVID-19 pandemic on ship NO2 pollution over European seas and find indications that NOx emissions from ships reduced by 20–25 % during the pandemic. The reductions in ship NO2 pollution start in March–April 2020, in line with changes in shipping activity inferred from AIS data.
A Source for the Continuous Generation of Pure and Quantifiable HONO Mixtures
Authors: Villena Guillermo , Kleffmann Jörg
Published: November 2021

Abstract. A continuous source for the generation of pure HONO mixtures was developed and characterized, which is based on the Henry’s law solubility of HONO in acidic aqueous solutions. With the help of a peristaltic pump diluted nitrite and sulfuric acid solutions are mixed in a temperature-controlled stripping coil, which is operated with pure nitrogen or synthetic air at gas flow rates of 0.5–2 L min-1. Caused by the acidic conditions of the aqueous phase (pH ≈ 2.5), nitrite is almost completely converted into HONO, which partitions to the gas phase limited by its known solubility in water. The source shows a fast time response of ~2 min (0–90 %) at higher concentrations and an excellent long-time stability (2σ noise <1 %). The HONO emission of the source perfectly correlates with the nitrite concentration from the sub-ppb range up to 500 ppb. The rate of NOx formation increases quadratically with the HONO concentration from non-detectable values at atmospheric relevant HONO concentrations reaching a NOx content of 1.6 % at 500 ppb. A general equation based on Henry’s law is developed, whereby the HONO concentration of the source can be calculated using measured experimental parameters, i.e. nitrite concentration, liquid flow rates, gas flow rate, pH of the solution and temperature of the stripping coil. In the equation, the known Henry’s law constant of HONO in sulfuric acid solutions is used. For the calculation of the effective Henry’s law constant, the acid dissociation equilibrium of HONO/nitrite is used as a variable to adjust the theoretical HONO concentration to the measured values. From the average of all experimental data the equilibrium of HONO/nitrite is well described by pKa = 1021.53/T – 0.449. The pKa of 3.0±0.1 (1σ) at 25 °C is in good agreement with the range of 2.8–3.28 published in former studies. A standard deviation between all measured and theoretical HONO concentrations of only ±3.8 % was observed and a conservative upper limit accuracy of the HONO concentration of better 10 % is estimated. Thus, for the first time, a stable HONO source is developed, which can be used for the absolute calibration of HONO instruments.
