The Social License to Automate Task has investigated the social dimensions of user engagement with automated technologies in energy systems to understand how end-user trust to automate is built and maintained in different jurisdictions and cultural settings. The rapid uptake of renewable energy systems will require new automated technologies to balance energy supplies. Some developers are looking to locate these in households where energy is being used. This saves moving the energy from centralised generation sites (remote hydro, solar or wind). This report details the findings from a 2 year project with 16 researchers in 6 countries, 26 Case studies spanning electric vehicles, home and precinct batteries, air conditioners and other heat pumps.
Development of HFU-based permeability prediction models using core data for characterisation of a heterogeneous Oligocene sand in the Nam Con Son basin
Authors: Nguyễn Văn Hiếu , Nguyễn Hồng Minh , Phan Ngọc Quốc , Phạm Huy Giao
Published: December 2021

Core data by both routine and special core analysis are required to understand and predict reservoir petrophysical characteristics. In this research, a total number of 50 core plugs taken from an Oligocene sand (T30) in the Nam Con Son basin, offshore southern Vietnam, were tested in the core laboratory of the Vietnam Petroleum Institute (VPI).

The results of routine core analysis (RCA) including porosity and permeability measurements were employed to divide the study reservoir into hydraulic flow units (HFUs) using the global hydraulic elements (GHEs) approach. Based on five classified HFUs, 16 samples were selected for special core analysis, i.e., mercury injection capillary pressure (MICP) and grain size analyses for establishing non-linear porosity-permeability model of each HFU based on Kozeny-Carman equation, which provides an improved prediction of permeability (R2 = 0.846) comparing to that by the empirical poro-perm relationship (R2 = 0.633).

In addition, another permeability model, namely the Winland R35 method, was applied and gave very satisfactory results (R2 = 0.919). Finally, by integrating the results from MICP and grain size analyses, a good trendline of pore size distribution index (λ) and grain sorting was successfully obtained to help characterise the study reservoir. High λ came with poor sorting, and vice versa, the low λ corresponded to good sorting of grain size.
Factors affecting graduate completion of the master's thesis at the University of Cape Coast
Authors: Baafi-Frimpong Stephen
Published: December 2021

This study which was a descriptive survey, was basically to find out the factors that affected the completion of the masters thesis at the University of Cape Coast (UCC), Ghana. The primary purpose of the research was to identify factors that might be hindering masters degree students from completing their theses, thereby either delaying or forgoing the successful completion of the degree. The participants in this study were "Successful Thesis Graduates" (STGs), "All-But Thesis" students (ABTs) who were enrolled between the years 1989 and 1993 and lecturers who served as thesis supervisors within the same period. The five most significant factors identified as obstacles to completion of the thesis in order ofimportance were : (1) lack ofbooks and other relevant materials; (2) lack of financial resources; (3) students' lukewarm attitude or lack of seriousness; (4) supervisors' delay in vetting work submitted by students; (5) students' work demands or combining thesis work with other jobs.

Published: December 2021

The study investigated the impact of organizational treatment on job satisfaction among workers in selected tertiary institutions in Nigeria. This was for the purpose of ascertaining the organizational factors that could enhance job satisfaction among institutional workers in Nigeria. The study adopted the ex-post facto research design. A total of 200 respondents were selected from some Universities in Nigeria using purposive and stratified sampling techniques. The instrument used for the data collection was a set of questionnaire with reliability co-efficient of 0.79 using Cronbach Alpha formula. The four-null hypotheses were tested at 0.05 alpha level using Pearson product Moment Correlation and t-test statistical methods. The finding of the study revealed that there was a significant relationship between organizational treatment and workers’ job satisfaction. A significant relationship was also found between organizational treatment and workers’ attitude to work. Based on the findings of the study, it is recommended that workers’ involvement in planning and implementation of organizational programmes should be encouraged in order to motivate workers and foster job satisfaction. Also, the wages and salaries of the workers should be subjected to continuous review and promptly paid in order to foster their commitment to organizational goals.
Instructional language dilemma and challenges in Ghana's education system: any prospects?
Authors: Ankomah Y.A.
Published: December 2021

language plays a pivotal role in educational provision and its quality as it is the main medium that facilitates communication between the learner and the teacher. Since the introduction of the first official school language policy in 1925, there has been the dilemma of what nature the policy is to take, spanning from first language as medium of instruction for the first three years of primary school, through first language usage for the first year only to an all-English usage for the first year only to an all –English usage throughout school. The study was a baseline cross-sectional survey on the perceptions of stakeholders on the language of instructions in Ghanaian basic schools. Eighty seven respondents comprising 36 pupils, 36 parents, nine teachers and three heads from three basic schools and six tutors from a college of education were interviewed on their views and perception on the used of the local language as medium of instruction in basic schools. The literature and the present study reveal that currently stakeholders will not support one exclusive language, English or Ghanaian first language, as medium of instruction at the early stages of school due to entrenched perceptions, not withstanding whatever possible advantages there may be. The obvious choice is a mother tongue-based bilingual arrangement that effectively combines the advantages of Ghanaian first language and English. But its success calls for commitment by policymakers and other stakeholders.
Utilization of computer technology in public universities in Ghana: Implications for management
Authors: Bosu Rosemary S.
Published: December 2021

This study investigated computer technology for instructional and administrative use in public universities in Ghana. Self-administered questionnaires were distributed to 450 academic staff and 98 administrators in three Ghanaian public universities: the University of Cape Coast (UCC), the University of Ghana (UG), and Kwame Nkrumah University of Science and Technologv (KNUST).Computers were generally available for both lecturers and administrators 10 use. Availability' and access to technology did not differ significantly between universities. Academic staff used computers mainly for preparing lecture notes or reports while administrators used them mainly for preparing memos and reports. Forty-five percent of lecturers and 58% of administrators reported low or moderate skills in the use of computers. A majority of the respondents obtained their skills through self intuition rather than formal tuition. The findings suggest that universities could improve the availability; access and skills in the use of relevant technologies as part of their staff development programmes. Progress could be monitored by current accreditation programmes.

Hannah Arendt e o conceito de felicidade pública
Authors: Turquino Turatto Ana Carolina , Müller Maria Cristina
Published: December 2021

O presente artigo é uma reflexão sobre o conceito de felicidade pública em Hannah Arendt. A própria terminologia, por si só, é controversa quando se parte das categorias do pensamento político, influenciado desde Platão, que propõe que o fim último da política e da ação está além do domínio público. Arendt propõe, no entanto, que os fins do governo e da ação política seriam a promoção da felicidade da sociedade, felicidade esta compreendida como felicidade pública. Mas resta, ainda, a pergunta: o que significa felicidade pública para a autora? Para o desenvolvimento desse conceito, Arendt remete tanto à Revolução Americana — e o seu anseio de tornar todos participantes do governo comum — quanto à Revolução Francesa — e a sua ideia de liberdade pública e a possibilidade de participação dos assuntos políticos. A pesquisa valeu-se da revisão bibliográfica das obras de Arendt, especialmente dos textos Ação e a busca da felicidade e Sobre a revolução e de seus comentadores. Ao final se depreendeu que a noção de felicidade pública proposta por Arendt trata da felicidade da participação nas questões políticas, da possibilidade da reunião, da alegria do discurso, da possibilidade de persuadir e ser persuadido, enfim, felicidade pública é a liberdade pública do agir em conjunto.
Tecnologia de monitoração eletrônica de pessoas no Brasil
Authors: Dezordi Wermuth Maiquel Ângelo , Chini Mariana , Cereser da Rosa Milena
Published: December 2021

A pesquisa tem como objeto a problemática envolvendo a efetivação de garantias fundamentais, constitucionalmente previstas, aos indivíduos monitorados eletronicamente. Como hipótese inicial percebe-se que muitas garantias fundamentais, embora constitucionalmente previstas, não são devidamente efetivadas aos indivíduos monitorados eletronicamente, gerando assim, prejuízos tanto aos apenados sujeitos à medida quanto aos seus familiares e sociedade em geral. Importante ressaltar que no Brasil, a tecnologia de monitoração eletrônica somente foi implementada no ano de 2010, com o advento da Lei Federal nº12.258/2010 que, por sua vez, alterou o Código Penal e a Lei de Execução Penal, incluindo a possibilidade de monitoração eletrônica à legislação brasileira, em casos de prisão domiciliar e saída temporária no regime semiaberto, sendo então uma alternativa positiva para o desencarceramento e reinserção social. O objetivo visa contribuir para as discussões relacionadas ao tema, trazendo visibilidade a medida e as dificuldades enfrentadas, possibilitando então, colaborar com perspectivas mais ativas de efetivação de garantias fundamentais aos indivíduos monitorados. À vista disso, com uma abordagem metodológica hipotético-dedutiva, com análise bibliográfica e legislativa, objetiva-se inicialmente realizar uma descrição sobre a medida da monitoração eletrônica desde sua origem até o início de sua utilização no Brasil para posteriormente, realizar breve exame da situação do instituto em relação à efetivação de garantias fundamentais previstas aos indivíduos vinculados à monitoração no país. Os resultados obtidos com a pesquisa confirmaram a hipótese inicial tendo em vista que a monitoração eletrônica resta prejudicada pela falta de implementação de políticas públicas voltadas ao cumprimento das garantias fundamentais aos apenados.
Pitting Mechanism of Mild Steel in Marginally Sour Environments: Pit Propagation Based on Acidification by Catalytic Oxidation of Dissolved Hydrogen Sulfide
Authors: Zhang Wei , Brown Bruce , Young David , Smith Stephen , Huizinga Sytze , Singer Marc
Published: December 2021

The present work studies pit propagation in marginally sour environments and proposes a credible mechanism. Both thermodynamic calculation and experimental measurement confirmed that H2S can be oxidized by traces of dissolved O2 into SO42– and H+ in the aqueous solutions near room temperature with the transitional metal ions serving as a catalyst. This acidification phenomenon would be more effective near the steel surface, especially inside a pit, where Fe2+ ions are most abundant. Therefore, the saturation degree of mackinawite would be lower inside the pit, which would prohibit the pitting from annihilation.
Narrativas sobre brincar nas infâncias: contribuições para a formação de professores de infância
Authors: Ferroni Carla de Oliveira , Sommerhalder Aline , Alves Fernando Donizete
Published: December 2021

Considerando que o brincar é um eixo estruturante do trabalho pedagógico na Educação Infantil que se estende aos anos iniciais do Ensino Fundamental, partiu-se do princípio de que é fundamental que os professores assumam uma posição ativa na organização e apoio ao desenvolvimento do brincar das crianças. Contudo, ainda é frágil na formação de professores (inicial e continuada) o reconhecimento e a valorização do brincar e, mais propriamente, das experiências de brincar vividas nas infâncias de professores. Consideramos que narrar as experiências vividas é uma atividade formativa, um instrumento de pesquisa, que coloca os professores no centro do processo e permite que conheçam suas histórias, apropriando-se delas e levando-os a refletir sobre aspectos que afetam a docência. O objetivo do estudo foi evidenciar e compreender aspectos sobre o brincar nas infâncias que afetam a constituição do ser professor. De abordagem qualitativa, essa pesquisa teve inspiração em histórias de vida e contou com a participação de três professoras e duas estudantes do curso de Pedagogia. Utilizou-se de narrativas escritas e orais. Como principais resultados, observou-se que o espaço e tempo para brincar, na infância das professoras, não incluem a escola como um lugar significativo; as professoras têm consciência de que suas experiências de brincar são diferentes das experiências de brincar das crianças com as quais trabalham; há uma multiplicidade de brincadeiras narradas e valorização da imaginação, fantasia e criatividade. As aprendizagens adquiridas por meio das experiências de brincar na infância das professoras corroboram a constituição do ser professor/a.
Goioerê - PR e algumas de suas transformações: o estudo da paisagem a partir da criação da COAGEL
Authors: Oliveira Dean Gomes de , Costa Pierre Alves
Published: December 2021

O artigo busca entender os elementos visíveis modificados no município de Goioerê, no decorrer da trajetória da extinta Cooperativa Agropecuária de Goioerê Ltda – COAGEL, que desde sua fundação até sua incorporação pela Coamo Agroindustrial Cooperativa em 2012, transformou a dinâmica regional no qual estava inserida. A metodologia ocorreu por meio de material bibliográfico, além de entrevistas, análise de fotografias e relatórios. Procurou-se assim, entender os agentes propulsores dessas transformações, pensando a paisagem como uma categoria de análise do espaço geográfico e sua estreita relação com o conceito de formação socioespacial. Conclui-se que houve modificação da paisagem goioerense, tanto no contexto urbano, como no rural, pois a COAGEL influenciou a sociedade em um todo, desde as plantações, até a espacialização dos loteamentos.
Novas configurações territoriais decorrentes da acumulação de capital no agronegócio de Mato Grosso: análise do município de Sorriso
Authors: Von Dentz Eduardo , Farias Fernando Rodrigo
Published: December 2021

O estado de Mato Grosso possui a soja como a principal atividade do setor agropecuário. Enquanto na safra 1997/98 o lucro médio atingido pelos produtores por saca de soja em Mato Grosso foi de R$2,39, na safra 2015/16 o lucro aumentou para R$31,30 por saca. Esse processo de ampliação da taxa de lucro tornou-se um importante fator que vem transformando a dinâmica econômica dos investimentos tanto endógenos quanto exógenos. O objetivo deste artigo é desvendar a capacidade de acumulação de capital do agronegócio de Mato Grosso e as configurações territoriais decorrentes dessa acumulação. Para alcançar o objetivo, utilizaram-se de quatro passos metodológicos: (1) levantamento de dados e levantamento bibliográfico; (2) trabalhos de campo e visitas técnicas; (3) organização e tratamento dos dados e informações coletadas; e (4) análise dos dados. Um dos principais resultados encontrados mostra que o capital acumulado no agronegócio da soja de Mato Grosso promove transformações territoriais tanto no próprio agronegócio quanto nas cidades.
Janelle Monáe’s The ArchAndroid
Authors: Favreau Alyssa
Published: December 2021

In Janelle Monáe’s full-length debut, the science fiction concept album The ArchAndroid, the android Cindi Mayweather is on the run from the authorities for the crime of loving a human. Living in 28th century Metropolis, Cindi fights for survival, soon realizing that she is in fact the prophesied ArchAndroid, a robot messiah meant to liberate the masses and lead them toward a wonderland where all can be free.

Taking into account the literary merit of Monáe’s astounding multimedia body of work, the political relevance of the science fictional themes and aesthetics she explores, and her role as an Atlanta-based pop cultural juggernaut, this book explores the lavish world building of Cindi’s story, and the many literary, cinematic, and musical influences brought together to create it. Throughout, a history of Monáe’s move to Atlanta, her signing with Bad Boy Records, and the trials of developing a full-length concept album in an industry devoted to the production of marketable singles can be found, charting the artist’s own rise to power. The stories of Monáe and of Cindi are inextricably entwined, each making the other more compelling, fantastical, and deeply felt.
Seafood poisoning, symptom, treatment, and prevention
Authors: Mustafa Murtaza , Yoshida Teruaki , Waheed Zarinah
Published: December 2021

Food related disease or food poisoning is prevalent worldwide with high mortality. Food related disease can be caused by bacteria, viruses parasites, enterotoxins, mycotoxins, chemicals, seafood poisoning e.g. histamine poisoning (scombroid) ciguatera, harmful algal bloom (HAB), and red tide. Illness can also result by red tide while breathing in the aerosolized brevitoxins (i.e. PbTx or Ptychodiscus toxins). Bacterial toxin food poisoning can affect within 1-6 hours, and 8-16 hours, and illness can be with or without bloody diarrhea. The common symptoms of food poisoning include abdominal cramps, vomiting and diarrhea. Diagnosis include examination of leftover food, food preparation environment, food handlers, feces, vomitus, serum and blood. Treatment with oral rehydration, antiemetic, anti-peristaltic drugs. Antimicrobial agents may be needed in the treatment of Shigellosis, cholera, and lifesaving invasive salmonellosis and typhoid fever. Proper care in handling and cooking raw poultry, beef, pork, and eggs is important to prevent any food borne diseases.

Physical Activity in Adults With Fatigue After Cancer Treatment
Authors: Twomey Rosie , Yeung Samuel , Wrightson James G. , Sung Lillian , Robinson Paula D. , Millet Guillaume Y. , Culos-Reed S. Nicole
Published: December 2021

Physical activity is recommended for the management of cancer-related fatigue (CRF), yet the evidence is primarily based on interventions delivered during cancer treatment, with no eligibility criterion for fatigue. There is a need to examine the quantity and quality of the existing literature on physical activity for clinically-relevant CRF that continues after cancer treatment (post-cancer fatigue). The objective of this systematic review was to summarize and evaluate the effect of physical activity on post-cancer fatigue in adults, using randomized trials where fatigue was an eligibility criterion. Studies were included if they: included adult participants with a cancer diagnosis who had completed initial cancer treatments (e.g., surgery, chemotherapy and/or radiation therapy); explicitly stated that fatigue was a participant eligibility/inclusion criterion, regardless of how this was described or assessed; involved a physical activity intervention; measured fatigue as a primary or secondary outcome. A previous systematic search was updated and electronic databases (Ovid MEDLINE(R), Ovid MEDLINE(R) and In-Process & Other Non-Indexed Citations, Embase, PsycINFO, Cochrane Database of Systematic Reviews, and CINAHL) were last searched on October 13, 2020. The risk of bias was assessed using the Cochrane Collaboration’s tool for randomized trials. A random-effects meta-analysis for the severity of fatigue across different scales at the end of the intervention was conducted. A total of 1035 participants were randomized across 19 studies. We estimate that less than 10% of the randomized trials of physical activity for CRF include people with post-cancer fatigue. The effect of physical activity on post-cancer fatigue was modest and variable (Hedge’s g -0.40; p = 0.010; 95% prediction intervals -1.41 to 0.62). Most studies had an unknown or high risk of bias, there was substantial heterogeneity between trials and evidence for the effect of physical activity on post-cancer fatigue was graded as low certainty. Including people with clinically relevant fatigue is a priority for future research in cancer survivorship. Additional transparently reported randomized clinical trials are needed to better understand the benefits of physical activity for post-cancer fatigue.

Scientists rely upon an accurate scientific literature in order to build and test new theories about the natural world. In the past decade, observational studies of the scientific literature have indicated that numerous questionable research practices and poor reporting practices may be hindering scientific progress. In particular, 3 recent studies have indicated an implausibly high rate of studies with positive (i.e., hypothesis confirming) results. In sports medicine, a field closely related to kinesiology, studies that tested a hypothesis indicated support for their primary hypothesis ~70% of the time. However, a study of journals that cover the entire field of kinesiology has yet to be completed, and the quality of other reporting practices, such as clinical trial registration, has not been evaluated. In this study we retrospectively evaluated 300 original research articles from the flagship journals of North America (Medicine and Science in Sports and Exercise), Europe (European Journal of Sport Science), and Australia (Journal of Science and Medicine in Sport). The hypothesis testing rate (~64%) and positive result rate (~81%) were much lower than what has been reported in other fields (e.g., psychology), and there was only weak evidence for our hypothesis that the positive result rate exceeded 80%. However, the positive result rate is still considered unreasonably high. Additionally, most studies did not report trial registration, and rarely included accessible data indicating rather poor reporting practices. The majority of studies relied upon significance testing (~92%), but it was more concerning that a majority of studies (~82%) without a stated hypothesis still relied upon significance testing. Overall, the positive result rate in kinesiology is unacceptably high, despite being lower than other fields such as psychology, and most published manuscripts demonstrated subpar reporting practices

Published: December 2021

A notary is an authorized public official whose main obligation is to make authentic deeds based on a professional code of ethics, related to the widespread indications of forgery of the authentic deeds, of course this needs to be accounted for by the notary himself. This study aims to identify and explain the criminal liability of a Notary against an authentic deed made and indicated forgery and to find out the legal status of a deed made by a Notary that caused a dispute. The data collection carried out in this research is by interview and literature study as well as the applicable legislation. Data were analyzed descriptively qualitatively. The results of the study indicate that if the notary is proven to have falsified or falsified the authentic deed he made and caused harm to interested parties, the notary can be sentenced to criminal, civil, and administrative sanctions. The legal status of the deed that is proven to be falsified by the Notary who made it, which can be canceled, null and void, has the power of proof as an underhand deed, canceled by the parties themselves and canceled by a court decision that has permanent legal force. However, the status or position of the Notary deed can’t be carried out jointly, but only applies to one, in accordance with a permanent court decision.

in). Manuscript I established that as the brushing days increase the remineralisation or dentin tubule occluded by each respective desensitising agent improved. It was found that the occluding capabilities of EB@TiO2 were more superior to both Pro-argin and NovaMin products in both saliva and without saliva. Manuscript II described the use of the logistic equation to predict the remineralisation of the EB@TiO2. Manuscript II established that the logistic equation effectively predicted the remineralisation trends of EB@TiO2 and Pro-argin toothpaste (Colgate Pro-relief). Manuscript III assesses the abrasivity of EB@TiO2 in comparison with calcium carbonate, and hydrated silica containing toothpaste. Bovine enamel specimen was used for the in vitro experiment. Manuscript III established that enamel loss from the brushed surface, regardless of the sample group, were statistically different when compared to the covered surface. The study found that the abrasivity of EB@TiO2 were comparable with the calcium carbonate toothpaste. It was also established that EB@TiO2 was less abrasive when compared against hydrated silica containing toothpaste. In conclusion, the experimental finding has exhaustively provided evidence on the suitability of EB@TiO2 as an active ingredient in toothpaste formulation. The study, therefore, provides new evidence and approach for the management of DH, particularly in low-income countries where the cost of oral healthcare may be too high.

Contrasting Genesis of Lateritic Bauxite on Granodioritic and Andesitic Rocks of Mempawah Area, West Kalimantan
Authors:   Geological Engineering, Institut Teknologi Bandung, Mildan Deni , Subandrio Andri S. , Bangun Prayatna ,   Aneka Tambang Building Tower A, Letjen. T.B. Simatupang St., No. 1, Jakarta 12530, Indonesia, Sunjaya Dedi
Published: December 2021

The lateritic bauxite deposits in the Mempawah area, West Kalimantan, were formed by the chemical weathering of Cretaceous granodioritic and andesitic rocks. They occurred locally on the low hills surrounded by swampy areas. Detailed surface geological mapping, test pits, mineralogical and geochemical analyses were performed to determine the characteristics and genesis of bauxite from different parent rocks. From bottom upward, the deposits are composed of fresh parent rocks, clay or pallid zone, bauxite zone with a few sparse ferricrete at the top of the bauxite zone, and soil. Bauxite derived from granodiorite exhibits brownish-red, massive, boulder to gravel-sized concretion in clay matrix and is composed of predominant gibbsite with subordinate kaolinite, quartz, goethite, and a minor amount of magnetite and hematite. In contrast, bauxite derived from andesitic rocks exhibits reddish-brown and is composed of predominant goethite. During the leaching process, SiO2 as a mobile compound decreased significantly in neutral pH, while Al2O3 and Fe2O3 precipitated as residual materials to form bauxite concretion. The enrichment anomaly of bauxite derived from andesitic rocks is caused by physio-chemical changes from hydrothermal alteration. Bauxite was formed by indirect bauxitization through the leaching of primary minerals under a tropical-humid climate.

Abstract. Atmospheric methane (CH4) concentrations have been rising since 2007, resulting from an imbalance between CH4 sources and sinks. The CH4 budget is generally estimated through top-down approaches using CH4 observations as constraints. The atmospheric isotopic CH4 signal, δ13C(CH4), can also provide additional constraints and helps to discriminate between emission categories. The oxidation by chlorine (Cl) likely contributes less than 5 % to the total oxidation of atmospheric CH4. However, the Cl sink is highly fractionating, and thus strongly influences δ13C(CH4). As inversion studies do not prescribe the same Cl fields to constrain CH4 budget, it can lead to discrepancies between estimates. To quantify the influence of the Cl concentrations on CH4, δ13C(CH4) and CH4 budget estimates, we perform multiple sensitivity simulations using three Cl fields with concentrations that are realistic with regard to recent literature and one Cl field with concentrations that are very likely to be overestimated. We also test removing the tropospheric and the entire Cl sink in other sensitivity simulations. We find that the realistic Cl fields tested here are responsible for between 0.3 % and 1.8 % of the total chemical CH4 sink in the troposphere and between 1.0 % and 1.2 % in the stratosphere. Prescribing these different Cl amounts in surface-based inversions can lead to differences in global CH4 source adjustments of up to 12.3 TgCH4.yr−1. We also find that the globally-averaged isotopic signature of the CH4 sources inferred by a surface-based inversion assimilating δ13C(CH4) observations would decrease by 0.53 ‰ for each additional percent of contribution from the tropospheric Cl sink to the total sink. Finally, our study shows that CH4 seasonal cycle amplitude is modified by less than 1–2 % but δ13(CH4) seasonal cycle amplitude can be modified by up to 10–20 %, depending on the latitude.

Abstract. Lightning is the major cause of the natural ignition of wildfires worldwide and produces the largest wildfires in some regions. Lightning strokes produce about 5 % of forest fires in the Mediterranean Basin and are one of the most important precursors of the largest forest fires during the summer. Lightning-ignited wildfires produce significant emissions of aerosols, black carbon, and trace gases, such as CO, SO2, CH4, and O3, affecting air quality. Characterization of the meteorological and cloud conditions of lightning-ignited wildfires in the Mediterranean Basin can serve to improve fire forecasting models and to upgrade the implementation of fire emissions in atmospheric models. This study investigates the meteorological and cloud conditions of lightning-ignited wildfires (LIWs) and long continuing current (LCC) lightning flashes in the Iberian Peninsula and Greece. LCC lightning and lightning in dry thunderstorms with a low precipitation rate have been proposed to be the main precursors of the largest wildfires. We use lightning data provided by the World Wide Lightning Location Network (WWLLN), the Earth Networks Total Lightning Network (ENTLN), and the Lightning Imaging Sensor (LIS) on board the International Space Station (ISS), together with four databases of wildfires produced in Spain, Portugal, southern France, and Greece, respectively, in order to produce a climatology of LIWs and LCC lightning over the Mediterranean Basin. In addition, we use meteorological data provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 reanalysis data set and by the Spanish State Meteorological Agency (AEMET), together with the Cloud Top Height product (CTHP) derived from Meteosat Second Generation (MSG) satellites measurements to investigate the meteorological conditions of LIWs and LCC lightning. According to our results, LIWs and a significant amount of LCC lightning flashes tend to occur in dry thunderstorms with weak updrafts. Our results suggest that LIWs tend to occur in clouds with a high base and with a vertical content of moisture lower than the climatological value, as well as with a higher temperature and a lower precipitation rate. Meteorological conditions of LIWs from the Iberian Peninsula and Greece are in agreement, although some differences possibly caused by the highly variable topography in Greece and a more humid environment are observed. These results show the possibility of using the typical meteorological and cloud conditions of LCC lightning flashes as proxy to parameterize the ignition of wildfires in atmospheric or forecasting models.

Abstract. The metallurgical industry in the Kola Peninsula, north-west Russia, form,
after Norilsk, Siberia, the second largest source of air pollution in the
Arctic and subarctic domain. Sulfur dioxide (SO2) emissions from the
ore smelters are transported to wide areas, including Finnish Lapland. We
performed investigations on concentrations of SO2, aerosol precursor
vapours, aerosol and ion cluster size distributions together with chemical
composition measurements of freshly formed clusters at the SMEAR I station
in Finnish Lapland relatively close (∼ 300 km) to the Kola
Peninsula industrial sites during the winter 2019–2020. We show that highly
concentrated SO2 from smelter emissions is converted to sulfuric
acid (H2SO4) in sufficient concentrations to drive new particle
formation hundreds of kilometres downwind from the emission sources, even at
very low solar radiation intensities. Observed new particle formation is
primarily initiated by H2SO4–ammonia (negative-)ion-induced
nucleation. Particle growth to cloud condensation nuclei (CCN) sizes was
concluded to result from sulfuric acid condensation. However, air mass
advection had a large role in modifying aerosol size distributions, and
other growth mechanisms and condensation of other compounds cannot be fully
excluded. Our results demonstrate the dominance of SO2 emissions in
controlling wintertime aerosol and CCN concentrations in the subarctic
region with a heavily polluting industry.

Abstract. This study gives a systematic comparison of the Tropospheric Monitoring Instrument (TROPOMI) version 1.2 and Ozone Monitoring Instrument (OMI) QA4ECV tropospheric NO2 column through global chemical data assimilation (DA) integration for the period April−May 2018. DA performance is controlled by measurement sensitivities, retrieval errors, and coverage. The smaller mean relative observation errors by 16 % in TROPOMI than OMI over 60° N−60° S during April−May 2018 led to larger reductions in the global root mean square error (RMSE) against the assimilated NO2 measurements in TROPOMI DA (by 54 %) than in OMI DA (by 38 %). Agreements against the independent surface, aircraft-campaign, and ozonesonde observation data were also improved by TROPOMI DA compared to the control model simulation (by 12−84 % for NO2 and by 7−40 % for ozone), which were more obvious than those by OMI DA for many cases (by 2−70 % for NO2 and by 1−22 % for ozone). The estimated global total NOx emissions were 15 % lower in TROPOMI DA, with 2−23 % smaller regional total emissions, in line with the observed negative bias of the TROPOMI version 1.2 product compared to the OMI QA4ECV product. TROPOMI DA can provide city scale emission estimates, which were within 10 % differences with other high-resolution analyses for several limited areas, while providing a globally consistent analysis. These results demonstrate that TROPOMI DA improves global analyses of NO2 and ozone, which would also benefit studies on detailed spatial and temporal variations in ozone and nitrate aerosols and the evaluation of bottom-up NOx emission inventories.
