Authors: Baji Fatima , Azadeh Fereydoun , Sabaghinejad Zivar , Zalpour Amir
Published: September 2021

E-learning can address some of the unmet needs of learners and educational communities; however, not all learners and educators accept e-learning as a delivery modality. This research endeavored to study the factors which affect e-learning acceptance among Iranian post-graduate students using the Davis Technology Acceptance Model (TAM) and to identify the changes which would facilitate their improved acceptance and subsequent wider use of e-learning. This descriptive-correlation study was conducted by surveying 320 Iranian postgraduate students using a self-reporting questionnaire. Structural equation modeling was used for data analysis through LISREL software. Results revealed sufficient validity and reliability of the TAM among Iranian postgraduate medical students. Perceived ease of use, perceived usefulness of e-learning, students’ attitudes toward e-learning, and the intention to use e-learning positively affected e-learning’s acceptance (p < 0.05) among Iranian postgraduate students. According to the results, attitudes toward e-learning have more predictive power than other TAM constructs. Therefore, emphasis on students’ favorable attitudes toward e-learning can be effective in accelerating its acceptance and will progress students’ learning outcomes.
Global learning: Definition, assessment, and approaches
Authors: Zhou Jiangyuan
Published: September 2021

Global learning has become a fundamental aspect of international education. Yet, a clear understanding of global learning and how to develop it remain unclear. Using the dynamic systems approach, this paper analyzed the reasons, methods, and knowledge, skills, and attitudes(KSA) of global learning in higher education. Global learning is the higher education institutions’ critical response to globalization. It is the essential learning outcome of comprehensive internationalization of curriculum requiring students to develop KSA about the external world and their internal selves in their daily lives across local and global communities. With survey results from 142 undergraduate students in one U.S. university and a global learning rubric and publication, this paper demonstrated how global learning is interpreted and approached differently at various levels and further proposed pedagogical approaches to enhance global learning in higher education.

Authors: Tomaz Maria Alexsandra , Tomaz Antonio Alex Dayson
Published: September 2021

Introdução: O aquecimento global é o aumento da temperatura média terrestre, causado pelo acúmulo de gases poluentes na atmosfera, sendo um dos maiores problemas ambientais. O aquecimento global acontece com o aumento da concentração dos gases de efeito de estufa, causando alteração nas trocas de calor, ficando a maior parte retida na atmosfera, aumentando a temperatura. Contudo, existem outros fatores que emitem esses gases, como, por exemplo, uso de combustíveis fósseis, produção de eletricidade a partir de combustíveis fósseis, desflorestação, queimadas, atividades industriais, entre outros. Objetivos: O objetivo do presente trabalho foi realizar uma reflexão sobre o aquecimento global, suas causas e consequências. Metodologia: Empregou-se como metodologia a realização de uma revisão bibliográfica. Resultados: Os gases poluentes formam uma espécie de "estufa" em volta do planeta que impedem que a radiação solar se espalhe para o espaço. As principais consequências do aquecimento global são alteração da fauna e da flora em todo o planeta; derretimento de grandes massas de gelo das regiões polares, aumentando o nível das águas do mar; aumento dos desastres naturais como, por exemplo, inundações, tempestades e furações; extinção de espécies; desertificação de áreas naturais; secas frequentes e mudanças de temperatura que podem afetar a agricultura. Conclusão: É necessário que as pessoas modifiquem seus hábitos para a diminuição dos impactos do aquecimento global. Há diversas atitudes que podem contribuir para isso como, por exemplo, usar álcool combustível e andar menos de automóvel, dando preferência ao transporte coletivo e bicicletas, economizar energia elétrica, evitar o desperdício de alimentos, reciclar produtos e materiais, entre outros.

Published: September 2021

Introdução: As transformações das civilizações ao longo da história é um fenômeno natural. Nas sociedades modernas e contemporâneas a ocorrência e a intensidade de tais fenômenos se aceleraram com as ações antrópicas. Talvez esse seja o principal problema da humanidade. Criou-se uma nova era geológica, o “Antropoceno” ou “Era da Humanidade”. Conceito controverso na comunidade científica, mas as evidências são significativas, dando crédito a teoria. Termo, criado em 1980 pelo biólogo “Eugene Stoermer”, popularizado pelo Prêmio Nobel de Química “Paul Crutzen” em meados do ano de 2000, com raízes no grego “anthropos” = homem e “cenos” = novo. Esse sufixo nomeia o conjunto de épocas do período “Quaternário” que vivemos atualmente. O “Painel do IPCC”, divulgado no mês de agosto de 2021, dá-nos visão global da gravidade e justifica a pesquisa. Objetivos: Observar se a sociedades estão se mobilizando para amenizar as mudanças climáticas e se estão conseguindo mudar o comportamento histórico de negligenciar o meio ambiente. Material e Métodos: Pesquisa básica, qualitativo, exploratório e bibliográficos, com objetivo descritivo. A metodologia é a análise documental (redução, apresentação, delineamento, verificação dos resultados e conclusão). Resultados: A revisão bibliográfica, os documentos pesquisados e observações ao longo da pesquisa, levam-nos crer que as sociedades não se conscientizaram da gravidade que o tema deve ser tratado. Os esforços das instituições mundiais, como ONU etc.; esclarecendo as sociedades do problema, esforços que ainda carecem de melhora e as evidências como os recentes desastres naturais espalhados por todas as regiões do planeta, aliado a divulgação do documento do clima pelo “IPCC” em 2021, a ciência terá muito trabalho para mudar o comportamento das sociedades. Conclusão: É crucial, mudar o comportamento das sociedades para amenizar o avanço das mudanças climáticas. Ações globais e unificadas do setor produtivo mundial, ajuda e reduz o consumo, a exploração dos recursos naturais, da geração de lixo, poluição das águas superficiais e subterrâneas, do solo e da atmosfera.

Published: September 2021

Introdução: É conhecido o grande impacto ambiental gerado pela produção do cimento, tornando indesejável seu emprego desmedido. Por isso, tem-se buscado alternativas para alcançar maiores resistências se o aumento deste aglomerante na composição dos materiais cimentícios. Concomitantemente, há o esforço para a correta destinação e reutilização de resíduos produzidos pelo setor da construção civil. Os produtos cerâmicos ocupam uma parcela considerável deste setor, representando também uma soma notável dos resíduos gerados. Objetivos: Diante deste cenário, o objetivo deste trabalho foi avaliar o comportamento de argamassas cimentícias com adição de resíduos de telha cerâmica frente a sua resistência à compressão. Materiais e Métodos: Para isso, foram elaboradas duas composições com dois tipos de cimento, CP II e CP IV. As composições estudadas foram elaboradas com base no traço comumente empregado para argamassas convencionais, de 1:3 (cimento: areia fina natural) em massa. Para todas as misturas avaliadas, empregou-se uma relação água/cimento de 0,625, definida a partir da análise visual das trabalhabilidade. Para os traços com adição cerâmica, um teor de 1,25% de pó de telha, referente à massa de cimento, foi acrescentado à composição. Resultados: O estudo passou por três etapas: obtenção do pó de telha cerâmica, através da moagem dos resíduos coletados; caracterização granulométrica dos aglomerantes com e sem as adições cerâmicas; e realização do ensaio de resistência à compressão. A partir dos resultados comprovou-se a influência da adição de pó de telha tanto na granulometria quanto na resistência das composições. A adição tornou mais fina a granulometria do cimento CP II, enquanto que aumentou o diâmetro médio da composição com o cimento CP IV. Com relação à resistência à compressão, ambas misturas apresentaram aumento da propriedade, sendo mais evidente para a argamassa com CP IV, em que o aumento foi superior a 50% para 7 dias e 18% para 28 dias. Relaciona-se a mudança na curva granulométrica a este ganho de resistência podendo concluir que houve um efeito de empacotamento de partículas. Conclusão: Por outro lado, a diferença elevada nos valores mecânicos, principalmente a observada para o cimento CP IV, também pode ser atribuída a uma possível interação pozolânica entre o resíduo e a composição do cimento.

Authors: Mota Zilândia Maria , Silva Alisson Rocha Da
Published: September 2021

Introdução: A crescente escassez hídrica mundial constitui-se atualmente como o maior desafio à sobrevivência da humanidade. A oferta de água não consegue suprir a demanda de forma satisfatória. Esta situação de limitação hídrica se torna mais grave quando a observamos num contexto relacionado aos habitantes inseridos em áreas rurais, especificamente agricultores familiares, grupo que representa 77% dos estabelecimentos rurais brasileiros. Objetivo: Dessa forma, este trabalho teve como objetivo realizar um estudo sobre segurança hídrica e sua importância na Agricultura Familiar. Material e Métodos: Foi realizada uma revisão de literatura de caráter exploratório, onde foram consultadas publicações compreendidas entre o período de 2010 a 2020. Foram selecionadas 21 publicações obtidas através de sites governamentais e bases científicas eletrônicas que incluíam legislações, livros, periódicos e artigos científicos cuja temática abordou discussões acerca da segurança hídrica no contexto da Agricultura Familiar. Resultados: A sustentabilidade hídrica é alcançada através do acesso universal à água potável, saneamento e higiene, da melhoria na eficiência do uso da água para fins econômicos, fortalecimento da gestão igualitária, participativa e responsável da água, melhora do gerenciamento das águas residuais, preservação da qualidade da água e diminuição dos riscos de desastres naturais e influenciados pelas atividades humanas. O Brasil apresenta características que o coloca na condição de suscetibilidade à escassez de água, pois a distribuição não ocorre de forma uniforme em seu território. No Nordeste do país as secas tendem a ficarem mais severas em virtude das mudanças climáticas. Esse agravamento afeta especialmente os pequenos agricultores familiares, pois são mais vulneráveis, devido à baixa capacidade de adaptação frente às mudanças do clima. A escassez de água acarreta diversos problemas que ocasionam a desestabilização da estrutura econômica e redução da qualidade de vida e bem-estar das famílias que residem nestas localidades, consequentemente levando ao aumento do êxodo rural. Conclusão: A sustentabilidade do agricultor familiar só é conseguida através da segurança hídrica. Sendo água um elemento essencial para a produção agrícola, sua insuficiência compromete não somente a produção, mas também a qualidade de vida do agricultor.
DCT based Fusion of Variable Exposure Images for HDRI
Authors: Ramakrishnan Vivek , Pete D. J.
Published: September 2021

Combining images with different exposure settings are of prime importance in the field of computational photography. Both transform domain approach and filtering based approaches are possible for fusing multiple exposure images, to obtain the well-exposed image. We propose a Discrete Cosine Trans- form (DCT-based) approach for fusing multiple exposure images. The input image stack is processed in the transform domain by an averaging operation and the inverse transform is performed on the averaged image obtained to generate the fusion of multiple exposure image. The experimental observation leads us to the conjecture that the obtained DCT coefficients are indicators of parameters to measure well-exposedness, contrast and saturation as specified in the traditional exposure fusion based approach and the averaging performed indicates equal weights assigned to the DCT coefficients in this non- parametric and non pyramidal approach to fuse the multiple exposure stack.
The Combination of Narrative News and VR Games: Comparison of Various Forms of News Games
Authors: Feng Xiaohan , Murakami Makoto
Published: September 2021

The information explosion makes it easier to ignore information that requires social attention, and news games can make that information stand out. There is also considerable research that shows that people are more likely to remember narrative content. Virtual environments can also increase the amount of information a person can recall. If these elements are blended together, it may help people remember important information. This research aims to provide directional results for researchers interested in combining VR and narrative, enumerating the advantages and limitations of using text or non-text plot prompts in news games. It also provides hints for the use of virtual environments as learning platforms in news games. The research method is to first derive a theoretical derivation, then create a sample of news games, and then compare the experimental data of the sample to prove the theory. The research compares the survey data of a VR game that presents a story in non-text format (Group VR), a game that presents the story in non-text format (Group NVR), a VR game that presents the story in text (Group VRIT), and a game that presents the story in text (Group NVRIT) will be compared and analyzed. This paper describes the experiment. The results of the experiment show that among the four groups, the means that can make subjects remember the most information is a VR news game with a storyline. And there is a positive correlation between subjects' experience and confidence in recognizing memories, and empathy is positively correlated with the correctness of memories. In addition, the effects of "VR," "experience," and "presenting a story from text or video" on the percentage of correct answers differed depending on the type of question.
The Difference of Machine Learning and Deep Learning Algorithms
Authors: Wong Yew Kee
Published: September 2021

In the information era, enormous amounts of data have become available on hand to decision makers. Big data refers to datasets that are not only big, but also high in variety and velocity, which makes them difficult to handle using traditional tools and techniques. Due to the rapid growth of such data, solutions need to be studiedand provided in order to handle and extract value and knowledge from these datasets. Machine learning is a method of data analysis that automates analytical model building. It is a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns and make decisions with minimal human intervention. Such minimal human intervention can be provided using big data analytics, which is the application of advanced analytics techniques on big data. This paper aims to analyse some of the different machine learning algorithms and methods which can be applied to big data analysis, as well as the opportunities provided by the application of big data analytics in various decision making domains.

On the spectra of natural waves in a plasma waveguide in the presence of collisions
Authors: Dvinin Sergei , Sinkevich Oleg , Solikhov Dovlat , Kodirzoda Zafari
Published: September 2021

The dispersion characteristics of surface and evanescent waves in metal-dielectric-plasma-dielectric-metal structure in the presence of collisions are investigated analytically and numer

ically. In the absence of absorption, when the electron density passes through the doubled critical value, a rearrangement of the eigenwave structure, associated with the appearance of surface waves, occurs. A rearrangement also occurs in an absorbing plasma, but the numbers of reconnecting modes depend on the size of the structure and the ratio of the electron collision frequency to the field frequency. Correct consideration of this process is necessary for the analytical analysis of the field structure in plasma reactors, the design of plasma antennas, and the solution of other problems of plasma electrodynamics.

Published: September 2021

The article presents the results of the study of material entrainment (erosion) of the most heatstressed nodes of the three-phase alternating current plasma torch "Zvezda" of megawatt power: electrodes and confusers. The data on entrainment were obtained by weighing the studied nodes after their cycles of operation at fixed modes. Air was used as the working fluid. The operating modes of the plasma torch varied in the ranges of arc power 0.5–1.2 MW, cur-rents 160–400 A, gas flow 70–170 g/s. When using different output nozzles, the pressure in the plasma torch varied from 0.2 to 1.65 MPa. The influence of various parameters of the operat-ing mode on the service life of the plasma torch is shown. Using the obtained data on the ero-sion of electrodes and confusers, their resource was evaluated.

Published: September 2021

The removal of ammonia impurities (100–200 ppm) in a humid air flow with a flow rate of 30–150 m3/h by ultraviolet radiation of an low-pressure amalgam lamp with a wavelength of 185 nm and 254 nm was experimentally investigated. The presence of water vapor is necessary for the effective removal of impurities by UV radiation, since highly active OH and atomic hy-drogen H radicals are formed during the dissociation of water molecules. The presence of water droplets dramatically reduces the efficiency of cleaning. The main reactions of photooxidation are considered. The high efficiency of removing ammonia molecules by one photon of 185 nm is noted.

Authors:   , Olusanya John Olumide
Published: September 2021

In this study, the fatigue life of fiber reinforced composite (FRC) materials system was investigated. A nano-filler was used to increase the service life of the composite structures under cyclical loading since such structures require improved structural integrity and longer service life. Behaviour of glass fiber reinforced composite (GFRC) enhanced with various weight percentages (1 to 5 wt. %) of Cloisite 30B montmorillonite (MMT) clay was studied under static and fatigue loading. Epoxy clay nanocomposite (ECN) and hybrid nanoclay/GFRC laminates were characterised using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The mechanical properties of neat GFRC and hybrid nanoclay/GFRC laminates were evaluated. Fatigue study of the composite laminates was conducted and presented using the following parameter; matrix crack initiation and propagation, interfacial debonding, delamination and S–N relationship. Residual strength of the materials was evaluated using DMA to determine the reliability of the hybrid nanoclay/GFRC laminates. The results showed that ECN and hybrid nanoclay/GFRC laminates exhibited substantial improvement in most tests when compared to composite without nanoclay. The toughening mechanism of the nanoclay in the GFRC up to 3 wt. % gave 17%, 24% and 56% improvement in tensile, flexural and impact properties respectively. In the fatigue performance, less crack propagations was found in the hybrid nanoclay/GFRC laminates. Fatigue life of hybrid nanoclay/GFRC laminate was increased by 625% at the nanoclay addition up to 3 wt. % when compared to neat GFRC laminate. The residual strength of the composite materials revealed that hybrid nanoclay/GFRC showed less storage modulus reduction after fatigue. Likewise, a positive shift toward the right was found in the tan delta glass transition temperature (Tg) of 3 wt. % nanoclay/GFRC laminate after fatigue. It was concluded that the application of nanoclay in the GFRC improved the performance of the material. The hybrid nanoclay/GFRC material can therefore be recommended mechanically and thermally for longer usage in structural application.
Neuromodulation Technologies for the Treatment of Alzheimer Disease
Authors: Gunn Holly , Grobelna Aleksandra
Published: September 2021

There are not very many effective treatment options for Alzheimer disease most of the options have side effects and temporarily reduce symptoms rather than delay disease progression. Effective treatments with minimal side effects that prevent and reduce the severity of Alzheimer disease are needed. Neuromodulation techniques have recently emerged for the treatment of Alzheimer disease, with the hope of filling some of these treatment gaps.

Two invasive and 8 noninvasive techniques are described in this Horizon Scan, some with more published evidence than others. Deep brain stimulation, repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and transcranial alternating current stimulation have more published studies involving patients with Alzheimer disease. Technologies at an earlier stage of development and with fewer studies providing an evidence base include vagus nerve stimulation, ultrasound stimulation, electromagnetic stimulation, photobiomodulation, infrared stimulation, and auditory stimulation.

The evidence regarding neuromodulation techniques is mostly promising; however, most studies are preliminary or include fewer than 50 participants. Given the heterogeneous nature of Alzheimer disease and the variety of methods in which the different neuromodulation technologies can be used, more research is needed to determine the effectiveness and relative effectiveness of neuromodulation techniques and devices.

Limitations in the research include limited evidence on the long-term effects and cost-effectiveness of the techniques in the treatment of Alzheimer disease, as well as the clinical significance of the results in the published studies thus far.

Despite the limited evidence, the results emerging from the literature are hopeful for many people living with Alzheimer disease. Importantly, the lack of reported serious side effects is a hopeful start for many who currently experience difficulties with pharmaceuticals. Given the heterogeneous nature of Alzheimer disease, the increased variety in treatment options also offers hope in potentially finding more effective treatments for individuals living with the debilitating disease.

A 59 year-old man without past medical history was referred with biochemical features of cholestasis (aspartate aminotransferase (AST) 117 U/L, alanine aminotransferase (ALT) 83 U/L, gamma-glutamyl transferase (GGT) 1307 U/L, alkaline phosphatase (AP) 1803 U/L, total bilirubin 0,7 mg/dL), a strongly positive antimitochondrial M2 antibody (AMA-M2) titer (88 U), weight loss and abdominal pain since several months. He did not take any medications, nor there was a history of alcohol abuse or sexual risk behavior. Upon presentation, clinical examination showed a rather cachectic patient (body mass index 19 kg/m²), without further abnormalities. As primary biliary cholangitis (PBC) was suspected, treatment with ursodeoxycholic acid had been initiated but did not improve the cholestasis nor the pain. Additional investigations didn’t reveal any other irregularities, except for a mildly dilated aortic sinus root of 42 mm. The histopathological findings of a liver biopsy are shown below (Figure 1). This showed granulomas with cholangitis and increased presence of neutrophils, which raised suspicion for an infectious cause.

Erythema multiforme is an immune-mediated mucocutaneous disorder. Mucosal involvement usually affects the oral region, the genitals or the eyes. We report a case of esophagitis caused by erythema multiforme in a patient diagnosed with lung cancer. Esophageal manifestation in erythema multiforme is rarely seen. Besides esophagitis it can lead to esophageal strictures. Erythema multiforme is mostly triggered by infection or drugs but the association with malignancy has been described.

For training young pilots. Flight simulators enhance the safety measures, as the risk factor of severe injuries are eliminated since the training is now synthetic. However, flight simulators also require large space, large budget and does have many high end requirements, which are to be met in order to make the simulator respond and perform identical to that of a real aircraft. Flight simulators does have their hardware constraints and because of these limitations, the simulators are not of generic nature that supports different sort of aircrafts. In this paper, the simulator environment is deployed in virtual reality to simulate the similar controls on a stereoscopic environment. Deployment of the simulator is such, that experience of flying an aircraft from cockpit will give a sensational view to the user. Virtual reality is used in learning purpose, as normal person can experience what it will be like, to fly an aircraft

Abstract— The Novel Coronavirus generally, knows as COVID-19 which first appeared in Wuhan city of China in December 2019, spread quickly around the world and became a pandemic. It has caused an overwhelming effect on daily lives, Public health, and the global economy. Many people have been affected and have died. It is critical to control and prevent the spread of COVID-19 disease by applying quick alternative diagnostic techniques. COVID-19 cases are rising day by day around the world, the on-time diagnosis of COVID-19 patients is an increasingly long and difficult process. COVID-19 patient test kits are costly and not available for every individual in poor countries. For this purpose, screening patients with the established techniques like Chest X-ray images seems to be an effective method. This study used a deep learning data augmentation on a publicly available data set and train advanced CNN models on it. The proposed model was tested using a state-of-the-art evaluation measures and obtained better results. Our model, the COVID-19 images is available at (https://github.com/ieee8023/covid-chestxray-dataset) and for Non-COVID-19 images is available at (https://www.kaggle.com/paultimothymooney/chest-xray-pneumonia). The maximum accuracy achieved in the validation was 96.67%. Our model of COVID-19 detection achieved an average F measure of 98%, and an Area Under Curve (AUC) of 99%. The results demonstrate that deep learning proved to be an effective and easily deployable approach for COVID-19 detection.

Abstract. Assessment of bottom-up greenhouse gas emissions estimates through independent methods is needed to demonstrate whether reported values are accurate or if bottom-up methodologies need to be refined. We report atmospheric methane (CH4) mole fractions and δ13CH4 measurements from Imperial College London since early 2018 using a Picarro G2201-i analyser. Measurements from March 2018 to October 2020 were compared to simulations of CH4 mole fractions and δ13CH4 produced using the NAME dispersion model coupled with the UK National Atmospheric Emissions Inventory, UK NAEI, and the global inventory, EDGAR, with model spatial resolutions of ~2 km, ~10 km, and ~25 km. Observed mole fractions were underestimated by 30–35 % in the NAEI simulations. In contrast, a good correspondence between observations and EDGAR simulations was seen. There was no correlation between the measured and simulated δ13CH4 values for either NAEI or EDGAR, however, suggesting the inventories’ sectoral attributions are incorrect. On average, natural gas sources accounted for 20–28 % of the above background CH4 in the NAEI simulations, and only 6–9 % in the EDGAR simulations. In contrast, nearly 84 % of isotopic source values calculated by Keeling plot analysis (using measurement data from the afternoon) of individual pollution events were higher than −45 ‰, suggesting the primary CH4 sources in London are actually natural gas leaks. The simulation-observation comparison of CH4 mole fractions suggests that total emissions in London are much higher than the NAEI estimate (0.04 Tg CH4 yr−1) but close to, or slightly lower than the EDGAR estimate (0.10 Tg CH4 yr−1). However, the simulation-observation comparison of δ13CH4 and the Keeling plot results indicate that emissions due to natural gas leaks in London are being underestimated in both the UK NAEI and EDGAR.

Abstract. Homogeneous freezing of aqueous solution aerosol particles is an important process for cloud ice formation in the upper troposphere. There the air temperature is low, the ice supersaturation can be high and the concentration of ice-nucleating particles is too low to initiate and dominate cirrus cloud formation by heterogeneous ice nucleation processes. The most common description to quantify homogeneous freezing processes is based on the water activity criterion (WAC) as proposed by Koop et al. (2000). The WAC describes the homogeneous nucleation rate coefficients only as a function of the water activity, which makes this approach well applicable in numerical models.
In this study, we investigate the homogeneous freezing behavior of aqueous sulfuric acid aerosol particles by means of a comprehensive collection of laboratory-based homogeneous freezing experiments conducted at the AIDA (Aerosol Interaction and Dynamics in the Atmosphere) cloud simulation chamber, which were conducted as part of 17 measurement campaigns since 2007. The most recent experiments were conducted during October 2020 with special emphasis on temperatures below 200 K. Aqueous sulfuric acid aerosol particles of high purity were generated by particle nucleation in a gas flow composed of clean synthetic air and sulfuric acid vapor, which was added to the AIDA chamber. The resulting chamber aerosol had number concentrations from 30 cm−3 up to several thousand per cubic centimeter with particle diameters ranging from about 30 nm to 1.1 µm. Homogeneous freezing of the aerosol particles was measured at simulated cirrus formation conditions in a wide range of temperatures between 185 and 230 K with a steady increase of relative humidity during each experiment. At temperatures between about 205 K and about 230 K, the AIDA results agree well with the WAC-based predictions of homogeneous freezing onsets. At lower temperatures, however, the AIDA results show an increasing deviation from the WAC-based predictions towards higher freezing onsets. For temperatures between 185 and 205 K, the WAC-based ice saturation ratios for homogeneous freezing onsets increase from about 1.6 to 1.7, whereas the AIDA measurements show an increase from about 1.7 to 2.0 in the same temperature range. Based on the experimental results of our direct measurements, we suggest a new fit line to formulate the onset conditions of homogeneous freezing of sulfuric acid aerosol particles as an isoline for nucleation rate coefficients between 5×108 and 1013 cm−3 s−1. The potential significant impacts of the higher homogeneous freezing thresholds, as directly observed in the AIDA experiments under simulated cirrus formation conditions, on the model prediction of cirrus cloud occurrence and related cloud radiative effects are discussed.
