Adaptive AUV-assisted diver navigation for loosely-coupled teaming in undersea operations
Authors:   , O’Neill Brendan
Published: October 2023

Human divers face immense challenges in the undersea domain due to constraints on life support, sensory input, and mobility. Due to these challenges, even simple tasks are difficult, and navigation between points of interest is key among them. However, humans have progressively utilized creativity, innovation, and research to explore the Earth’s oceans at greater depths and with increased spatial and temporal detail. Autonomous underwater vehicles often lack the tools, dexterity, or flexibility to manage specific tasks or unforeseen circumstances. However, advances in inertial navigation, computation, and acoustic communication enable autonomous underwater vehicles to perform tasks outside human capability. Acoustic modem technology allows for flexible and reliable communication over an acoustic link. We propose algorithms for cooperative navigation between a diver and an autonomous underwater vehicle as a pathway toward complex undersea human-robot teams. This thesis identifies the communication, software, and algorithmic tools to enable loosely-coupled cooperative navigation between an autonomous underwater vehicle and a diver without a surface presence. Divers present new challenges for cooperative navigation based on their unique motion profile and variable pace from diver to diver. By leveraging the vehicle’s sensor suite, acoustic modem technology, and nonlinear least-squares state estimation, we enable enhanced diver localization and navigation without a surface presence. Adaptation to environmental impacts is explored through measured ocean currents as well as updates to the diver’s motion model based on state estimation analysis. These adaptations produce more efficient diver transits with fewer heading changes. In addition, maneuvering strategies for autonomous underwater vehicles are explored to assess their impact on diver localization accuracy. Experimental validation is shown through surface platforms as proxies for the autonomous underwater vehicle and diver, demonstrating the localization accuracy within a few meters for experiments under various operating conditions. These contributions provide a foundation for undersea human-robot teams to engage in complex tasks with greater efficiency through their combined strengths.

Published: October 2023

The history of South Slavs in West European literature from the second half of the 17th century to the early 19th century. The aim of this article is to present the most important issues related to West European perceptions of the history of South Slavs in the second half of the 18th and the early 19th century, a time of an increased interest in Slavic history, a process that ran parallel to the development of the Enlightenment perception of history. The analysis shows that in the second half of the 18th c. and the early19th c., in the face of the increasing weakness of Ottoman Turkey, the local Slavic communities were rediscovered in the Balkans. Although West European historiographies were familiar with them, the invention of new historical tools and contexts in the Age of Enlightenment resulted in a selective treatment thereof. It made it easy to consider South Slavs as uncivilised communities which, contrary to historical facts, remained at a primitive, tribal stage of development.

Abstract: This manuscript aims to report the nutrition transition in Brazilian children under 5 years old from 2006 to 2019. Microdata from the Brazilian National Survey on Demography and Health of Women and Children (PNDS 2006) and the Brazilian National Survey on Child Nutrition (ENANI-2019) were analyzed. The indicators considered were: micronutrient status (anemia and vitamin A deficiency), anthropometric status (stunting and excessive weight), and breastfeeding practice (exclusive breastfeeding among children < 6 months and continued breastfeeding among children 12-23 months). We also analyzed minimum dietary diversity (MDD), consumption of ultra-processed foods, consumption of meat or eggs, and not consuming fruits or vegetables in children 6-59 months of age only for ENANI-2019. Equiplot charts were generated according to geographic region, maternal schooling level, and maternal race/skin color. From 2006 to 2019, the prevalence rates of anemia and vitamin A deficiency decreased from 20.5% to 10.1% and 17.2% to 6%, respectively. The prevalence of stunting remained at 7%, and excessive weight rates increased from 6% to 10.1%. The prevalence of exclusive breastfeeding among children < 6 months increased from 38.6% to 45.8%, and of continued breastfeeding among children 12-23 months from 34.6% to 43.6%. In 2019, 61.5% of children achieved the MDD, 88.8% consumed ultra-processed foods, 83.1% consumed meat or egg, and 25.7% did not consume fruits or vegetables the day before the survey. Trends of decreased micronutrient deficiencies, increased breastfeeding, and excessive weight rates, as well as reductions in disparities related to geographic region, maternal schooling level, and maternal race/skin color, were observed for most of the indicators.

Published: October 2023

Abstract This in vitro study synthesized hybrid nanofibers embedded in graphene oxide (GO) and incorporated them into experimental resin composite monomers to evaluate their physical-mechanical properties. Inorganic-organic hybrid nanofibers were produced with precursor solutions of 1% wt. GO-filled Poly (d,l-lactide, PLA) fibers and scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) characterized the morphology and chemical composition of the spun fibers. Resin composite monomers were developed and a total of 5% nanofibers were incorporated into the experimental materials. Three groups were developed: G1 (control resin monomers), G2 (resin monomers/PLA nanofibers), and G3 (resin monomers/inorganic-organic hybrid nanofibers). Contact angle (n=3), flexural strength (n=22), elastic modulus (n=22), and Knoop hardness (n=6) were evaluated. The mean of the three indentations was obtained for each sample. The normality of data was assessed by QQ Plot with simulated envelopes and analyzed by Welch's method (p<0.05). Overall, SEM images showed the regular shape of nanofibers but were non-aligned. Compositional analysis from EDS (n=6) revealed the presence of carbon and oxygen (present in GO composition) and Si from the functionalization process. The results of contact angle (°) and hardness (Kg/mm2) for each group were as follow, respectively: G1 (59.65±2.90; 37.48±1.86a), G2 (67.99±3.93; 50.56±1.03b) and G3 (62.52±7.40; 67.83±1.01c). The group G3 showed the highest Knoop hardness values (67.83 kg/mm2), and the flexural strength of all groups was adversely affected. The experimental resin composite composed of hybrid nanofibers with GO presented increased hardness values and hydrophilic behavior.

Abstract This study was aimed at analyzing the surface properties of a universal resin composite and evaluating the effect of preheating on its physicochemical properties. Two commercial resin composites were used under two conditions: Filtek Universal Restorative (UR); UR preheated (URH); Filtek Supreme (FS) and FS preheated (FSH). The film thickness (FT) test (n = 10) was done using two glass slabs under compression. Flexural strength (FLS) and modulus (FLM) were evaluated using a three-point flexion test (n = 10). Polymerization shrinkage stress (PSS) was evaluated in a universal testing machine (n = 5). Gap width (GW) between composite and mold was measured in internally polished metallic molds (n = 10). The degree of conversion (DC) was evaluated by Fourier Transform Infrared spectroscopy (n = 3). The morphology of the filler particles was checked by scanning electron microscope (SEM) and EDX analysis. Surface gloss (SG) and surface roughness (SR) were evaluated before and after mechanical brushing (n = 10). The outcomes were submitted to 2-way ANOVA and Tukey's test (α = 0.05). Lower mean values of FT were observed for the preheated groups when compared to the non-preheated groups. URH and FSH showed higher mean values of FLS and FLM when compared with UR and FS. No differences were observed between groups in the PSS test. The GW was higher for the UR and FS groups when compared with URH and FSH. The DC was higher for preheated resin composites when compared to the non-preheated groups. The SR of the UR composite was higher than the FS after mechanical brushing, while the SG was higher for the FS groups. In conclusion, the universal resin composite tested generally presented similar physicochemical properties compared with the nanofilled resin composite and either similar or slightly inferior surface properties. The preheating improved or maintained all properties evaluated.

Abstract This study aimed to assess the influence of the file format on the image quality parameters (image noise, brightness, and uniformity) of periapical radiographs acquired with different digital systems. Radiographic images of an acrylic phantom were acquired with two digital systems - Digora Toto and Express, and exported into five different file formats - TIFF, BMP, DICOM, PNG, and JPEG. Image noise, image brightness (mean of gray values), and image uniformity (standard deviation of gray values) were evaluated in all images. A two-way analysis of variance with Tukey’s test as a post-hoc test was used to compare the results, considering the file formats and radiographic systems as the studied factors. A significance level of 5% was adopted for all analyses. The DICOM image file format presented lower image noise, higher brightness (higher mean gray values), and greater image uniformity (p<0.001) than the other file formats, which did not differ from each other for both digital radiography systems (p>0.05). The Express system revealed lower image noise and greater image uniformity than the Digora Toto system regardless of the image file format (p<0.001). Moreover, the Express showed higher brightness than the Digora Toto for all image file formats (p<0.001), except for the DICOM image file format, which did not significantly differ between the digital radiography systems tested (p>0.05). The DICOM image file format showed lower image noise, higher brightness, and greater image uniformity than the other file formats (TIFF, BMP, PNG, and JPEG) in both digital radiography systems tested.

Published: October 2023

ABSTRACT: Feathers are by-products that are generated in significant quantities by the poultry industry. Microbial bioconversion has been investigated as a promising strategy for the processing of feathers, since, along with the degradation of these keratinous materials, bioprocessing can result in value-added products. Thus, from the perspective of industrial microbiology, chicken feathers can be considered a raw material for obtaining microbial proteases. Within this context, this research investigated and characterized the production of extracellular proteases by Aspergillus sp., isolated from soil of the Amazon Rainforest. The enzymatic production was evaluated using several growth substrates (whole feathers, feather meal, human hair, casein, gelatin, peptone and chicken beaks). With highest enzyme production was obtained the feather meal (FM) and peptone. After 48 h of fermentation, FM degradation was 15.82%. The crude protease showed optimal activity at pH 5.0 and 37 °C and enzymatic activity was enhanced with the addition of 1 and 5 mM of CaCl2, MnSO4, KCl, MgSO4 and CuSO4. The detergents Tween 20 and Triton x-100, at concentrations 0.5 and 1% (v/v), tended to stimulate activity. The presence of 0.5 and 1% (v/v) of organic solvents (methanol, acetone, butanol, acetonitrile, isopropanol and DMSO), maintained the enzymatic activity. β-mercaptoethanolstimulated proteolytic activity in the enzymatic assays. This study suggested new direction for waste management with industrial applications giving rise to green technology for sustainable development.

ABSTRACT Objective: To evaluate the clinical profile, pain improvement, and the need for surgical interventions in patients undergoing transforaminal block with the use of corticosteroids and anesthetics. Methods: This is a prospective, randomized, double-blind study with 45 patients with unilateral radicular pain in their lower limbs and a single-segment lumbar disc herniation diagnosis. In the intervention group, transforaminal blocks with bupivacaine, dexamethasone, and clonidine were applied and in the control group, distilled water and bupivacaine. The Oswestry questionnaire was applied. Results: We included 24 female (53.4%) and 21 male patients (46.6%). Of those with an occupation, 85.71% (n = 30) were relieved from their duties due to their illness and 14.29% (n = 5) continued to work with limitations. Those who underwent transforaminal block with an injection of corticosteroids, clonidine, and anesthetics showed immediate relief. However, such effect failed to alleviate patients’ symptoms after three weeks. We observed that 52% of patients showed varying degrees of improvement. The control group experienced mild pain relief after one week, which also failed to last after three weeks. Moreover, 50% of patients improved in varying degrees. Conclusion: Further studies with larger samples, new epidemiological data, and longer follow-ups are necessary to validate our hypotheses. Level of Evidence II, Prospective Study.

Resumo O artigo analisa a associação entre níveis de fadiga por compaixão e engajamento no trabalho com a COVID-19 em profissionais de enfermagem. Estudo longitudinal, tipo antes e depois, realizado com profissionais de enfermagem da linha de frente, nos períodos pré-pandêmico e pandêmico. Utilizou-se as versões brasileiras da Professional Quality of Life Scale e da Utrecht Work Engagement Scale. Observou-se altos níveis de satisfação por compaixão (≥43,0), baixos níveis de burnout (<23,0) e estresse traumático secundário (<23,0); e níveis altos de vigor (≥4,0 e ≤4,99), absorção (≥4,0 e ≤4,99) e escore geral (≥4,0 e ≤4,99). Houve correlação moderada, negativa e significativa do burnout com vigor (r: -0,505; p-valor: <0,001), no pré-pandemia; e com o escore geral, no pré-pandemia (r: -0,543; p-valor: <0,001) e período pandêmico (r: -0,458; p-valor: <0,001). Não houve alterações nos níveis de engajamento no trabalho. Profissionais com fadiga por compaixão tiveram redução do vigor, absorção e escore geral, classificados como médios no período pandêmico (≥2,0 e ≤3,99); e aumento da dedicação, que era baixa (≥1,0 e ≤1,99) no pré-pandemia. Concluiu-se não haver associação danosa entre fadiga por compaixão e engajamento no trabalho com a COVID-19 nos profissionais de enfermagem.

Abstract The COVID-19 pandemic has put pressure on public health systems worldwide since 2020. This article aims to discuss working conditions in Primary Health Care (PHC) in Brazil, while dialoguing with primary health care (CSP, Cuidados de Saúde Primários) in Portugal in the pandemic scenario. For that purpose, data from the study “Working conditions of health professionals in the context of COVID-19 in Brazil” are presented, for further discussion with the report produced by “Family Health Units - National Association (USF-AN, Unidades de Saúde Familiar - Associação Nacional)” on the CSP in Portugal. In Brazil, regarding the sample of 3,895 PHC health professionals, it was observed: multiple employment relationships, lack of institutional support and specific training, living with fake news and the lack of political cohesion between health authorities, with significant changes in these workers’ mental health. In Portugal, the increase in the workload and the presence of Burnout Syndrome among FHU professionals was emphasized. The pandemic had a significant impact on the health and daily work of health professionals in PHC and CSP. However, the Brazilian context was more adverse due to fake news and divergences regarding conducts related to the fight against the pandemic, due to the actions and denialism by the federal government.

Resumo Com o objetivo de analisar as relações interprofissionais produzidas a partir da alta responsável, na perspectiva e no agir da enfermagem durante o a pandemia de COVID-19, realizou-se um estudo qualitativo, tipo estudo de caso. A técnica de pesquisa foi a observação participante de uma enfermaria de hospital de grande porte do SUS na cidade de São Paulo. A produção de narrativas e a análise micropolítica das relações fez emergir dois planos de visibilidade: para além da alta responsável - a antropofagia dos arranjos tecnológicos do cuidado e a ambivalência da enfermagem na produção das relações interprofissionais; e alta médico-centrada e alta negociada - o entrecruzamento com outros profissionais, com as famílias e com a vida “como ela é”. A pandemia de COVID interrompeu as visitas multiprofissionais e foi um analisador das relações interprofissionais. A partir de uma inteligência astuciosa, a enfermagem negocia a alta com os médicos, que detêm este poder, e aciona a equipe, a partir de uma autonomia elástica. A alta responsável por si só não foi capaz de produzir um plano comum de ação interprofissional, de modificar os papéis instituídos no hospital, situação que recrudesceu durante a pandemia mas abriu condições para o aumento da profissionalização da equipe.

Abstract The objective of this study was to identify the meanings that Brazilians attribute to the vaccines against COVID-19. A non-probabilistic sample of 1,817 Brazilians was used, each of whom answered a sociodemographic questionnaire and then the free word association technique was applied, with the inducing stimulus “vaccine for COVID-19”. This data was analyzed using descriptive statistics in the SPSS software and the textual analysis was completed using IRaMuTeQ. The results were organized into classes: (1) “Vaccine - a glimmer of hope”, portraying the expectation of healing and freedom; (2) “Vaccine - a scientific response to prevention”, showing the role of research; and (3) “Vaccine - fears and political aspects”, highlighting obstacles to vaccination. The results also demonstrated differences in responses depending on the region; adhesion to isolation; history of infection and hospitalization for COVID-19; being a frontline health professional; and being from a risk group. It is concluded that understanding the meanings of vaccination is essential for planning more effective interventions in immunization.

GenoSSRFinder: a tool for rapid, precise, and targeted simple sequence repeat detection in genomic studies
Authors: Alhawatema M.
Published: October 2023

Abstract The GenoSSRFinder is a new tool enables the research of Simple Sequence Repeats (SSRs) in DNA sequences and genomes much simpler and more precise in short time. The analysis is carried out by targeting a certain SSR in genome and gene sequences. This utility is quick, accurate, and does its function quite well. It quickly goes across the sequence, revealing all of the locations at which the selected SSR may be found. This tool will tell researchers where selected SSR begins and where it stops, how long it is, how often it repeats, and how long each repetition is. GenoSSRFinder gets the findings quickly, and they will be simple to comprehend. Therefore, when studying SSRs, researchers will have more time to use to thorough work as a result of this time savings. In addition, it provides a valuable information since it is highly precise. GenoSSRFinder is simple to use and produces high-quality findings. It is also accelerating SSRs gene research, which is a direct result of the new approach we use to analyse SSRs. Three case studies in this study demonstrated the usefulness of this program by immediately studying a particular SSR that was associated with genetic illness, biodiversity and criminal science in living organisms. This demonstration explains that GenoSSRFinder might be utilized in a wide variety of fields, such as the research of genetic illnesses, the biodiversity and genetic studies, or even in criminal investigations.
Análise do potencial de Angola para a instalação de centrais termoelétricas a biomassa vegetal
Authors: Sousa Oloiva , Lucas Maria Raquel , Aranha José
Published: October 2023

Resumo O aumento da produção de energia elétrica com base em combustíveis fósseis conduz ao aumento de gases com efeito estufa e a originar conflitos devido ao aquecimento global. Por estes motivos, também é crescente o número de estudos relativos a fontes alternativas de energia sustentável. A biomassa florestal pode ser uma importante fonte de combustível para unidades produtoras de energia, como sejam as centrais termoelétricas. Vários estudos, em Portugal, demonstraram que a quantidade anual de resíduos agroflorestais pode constituir uma fonte alternativa de combustível para as centrais termoelétricas. Ainda que a produção agroflorestal e pecuária, em Angola, seja diferente da praticada em Portugal, a produção de resíduos agroflorestais e a forma de os aproveitar segue os mesmos princípios. O objetivo do presente trabalho é o de estimar, através do processamento de imagens do satélite MODIS, a disponibilidade em biomassa florestal e identificar locais com potencial para a instalação de centrais termoeléctricas a biomassa vegetal. O trabalho foi desenvolvido em ambiente de sistemas de informação geográfica e deteção remota. As imagens MODIS permitiram calcular o índice de vegetação NDVI e estimar a biomassa existente recorrendo a formulários anteriormente apresentados por outros autores. Através de técnicas de álgebra cartográfica, introduziram fatores condicionantes à instalação das centrais, como sejam a morfologia do terreno, a proximidade à rede viária e a proximidade a reservas naturais. Os resultados obtidos mostram que Angola possui um potencial em biomassa florestal que permite instalar até 17 centrais de 11 GWh-1, sendo que 12 se localizam próximo da atual rede elétrica de alta tensão ou em situação de ligação direta à rede. Destas 12, 4 estão próximas das atuais centrais elétricas hídricas, pelo que poderão funcionar em complemento de produção. Os resultados também mostram que as fazendas dedicadas à produção florestal se localizam próximo das zonas de ação das centrais e da rede ferroviária. Assim, os resíduos de exploração florestal que estas fazendas geram poderão ser comercializados como combustível para estas centrais. Também as fazendas dedicadas à produção agrária se localizam próximo das potenciais centrais, pelo que poderão usar a energia produzida e vender os seus resíduos vegetais como combustível.
Transformações no debate público sobre a política de drogas (2003-2016): uma análise a partir das publicações do jornal Zero Hora1
Authors: Silva Marcelo Kunrath , Ferreira Cristiano Nicola
Published: October 2023

O objetivo deste artigo é analisar como se estrutura e se transforma o debate público sobre a política de drogas no Brasil entre os anos de 2003 e 2016. Para responder a essa problematização, foram analisados 306 materiais publicados no jornal Zero Hora. A análise demonstra que houve mudanças significativas na configuração do debate público sobre o "problema das drogas" no país na última década. Mais especificamente, é demonstrado que o debate público tende a ser mais heterogêneo, em termos de agentes e de enquadramentos, do que aquilo que se expressa na política de drogas vigente. Identificar e analisar essa heterogeneidade é importante para a compreensão das controvérsias e das posições em disputa sobre a política de drogas.
Pés-de-lótus: considerações sobre a mulher chinesa em Passaporte para a China, de Lygia Fagundes Telles
Authors: Marchioro Camila
Published: October 2023

Resumo Em 1960, Lygia Fagundes Telles partiu para uma viagem à China a convite do regime comunista. Suas impressões foram registradas nas crônicas publicadas à época no jornal Última Hora e posteriormente reunidas no livro Passaporte para a China (2011). O presente artigo analisa as impressões que Lygia tece sobre a China a partir do encontro com duas mulheres no regime maoísta. Além disso, o trabalho discorre sobre como suas crônicas dialogam com a tradição da narrativa de viagem, especificamente em relação aos relatos sobre o Oriente. Como resultado, observa-se que as crônicas sinalizam aspectos relativos à constituição de uma identidade da cronista ao mesmo tempo que permitem observar tensões nas relações de gênero e classe na China maoísta, além de, a partir do caso chinês, viabilizarem uma reconfiguração do olhar do seu leitor a respeito das questões de gênero em nosso país.

ABSTRACT. Stress during aging is not uncommon and dysfunctional family relationships are important sources of stress in the elderly. Considering the potential stressor that family dysfunction represents, it is questioned whether prolonged exposure to dysfunctional family arrangements can contribute to cognitive decline in aging. Objective: To verify whether family dysfunction is a predictive factor of cognitive decline in aging. Methods: Secondary study with analysis of existing data from the longitudinal, population-based study “Health, Wellbeing and Aging” (SABE). Data from 791 elderly people from two cohorts of the SABE study between 2006 and 2015 were analyzed. Family dysfunction was assessed using the Apgar family instrument, while cognitive performance was assessed using the Mini-Mental State Examination (MMSE), verbal fluency (animals) and digit length in reverse order. Cognitive decline was measured by the difference in scores in the period between 2006 and 2015. Results: Approximately 10% of the sample had family dysfunction. The familial Apgar score was not associated with decline on MMSE (p=0.732), verbal fluency (p=0.852) and digit span scores (p=0.718). Scores related to cognition and family functionality, such as age, education, living alone, depression and family Apgar, do not explain cognitive decline. Conclusion: The findings indicate that family functioning is not associated with cognitive decline in community-dwelling elderly. New studies will be needed to analyze the qualitative characteristics of family relationships in the cognitive performance of the elderly.

ABSTRACT. The high prevalence of Alzheimer's disease and dementia is a growing concern for healthcare systems and patients. Objective: The primary objective of our study was to assess the association of depression and heart disease on the risk of dementias like Alzheimer's disease or vascular dementia in patients. Methods: This retrospective study used electronic health records data that was provided by the HealthVerity™ Marketplace. The characteristics of the patient population were recorded and the risk of dementia was examined using adjusted logistic regression models. Results: The analysis included 49,735 participants and revealed that patients who have heart disease or depression had a higher risk of dementia. Patients who had both heart disease and depression were over three times more likely to have dementia and Alzheimer's disease, and over five times more likely to have vascular dementia compared to patients who only have a diagnosis of heart disease. Depression was associated with a fourfold increase in the risk of dementia. Participants with a diagnosis of most types of heart disease as well as depression had increased risk for developing dementia. Conclusion: This study revealed that patients with both heart disease and depression had increased odds of having dementia as well as vascular dementia and Alzheimer's disease. These findings may serve to support policies and healthcare decision-making to increase preventive measures for dementia and Alzheimer's disease among patients with both depression and heart disease.
Conceptualising and framing STEAM education: what is (and what is not) this educational approach?
Authors: Rodrigues-Silva Jefferson , Alsina Ángel
Published: October 2023

abstract: STEAM is a recent educational approach intending the interdisciplinary teaching of science, technology, engineering, arts/humanities, and mathematics. The literature reports conceptual confusion that frequently diverts STEAM practice and research to issues concerning particular activities or contexts. Therefore, we carried out a narrative review of articles indexed in the Web of Science (WoS) to elucidate STEAM education’s history, epistemology, and divergences. As a strategy, we first focused on documents that could offer a panoramic view of the object of study – literature reviews and articles about STEAM frameworks. Through them, we identified essential discussion points and further expanded the review. As a result, we articulated rationalities about why STEAM is not a mere evolution of STEM, a teaching methodology, or just a synonym for interdisciplinarity. Furthermore, we discussed the appropriateness of interdisciplinarity in STEAM – since it is strongly supported by the disciplines and their intersections – instead of pursuing transdisciplinarity, meaning knowledge remains undefined in a holistic whole. We differentiated STEAM disciplines (list of the five knowledge areas), STEAM activities (interdisciplinary teaching unity of at least two STEAM disciplines), and STEAM education (educational approach of interdisciplinarity between all five disciplines). Finally, we defined and proposed a framework for STEAM in a table format that stresses two necessary and sufficient conditions – interdisciplinarity and the five acronym areas. The framework permits envisioning the plurality of teaching methodologies and educational objectives consistent with STEAM.
