Pesquisa do Estado do Amazonas The present work presents a vast bibliographical research that, allied to the research in loco, made possible the process of its intellectual craft. Tools adapted and adapted to the reality of those involved in the field research were used, namely, open interviews and forms with questions relevant to the theme, as well as the categories of analysis chosen for a better understanding of territory management in the S??o Francisco Community. Thus, territorial management, agroecosystems and governance were the 03 (three) categories of analysis that guided the research and contributed to the achievement of its general objective, which was to analyze territorial management in the S??o Francisco Community in the municipality of Careiro da V??rzea (AM) , and also the reach of the specific objectives, which unfolded in 03 (three) chapters, each one addressed essential questions for the elucidation of how the territorial management happens in the study area. Studies regarding the management of territories are present in the academy, but few are focused on the Amazonian reality of the floodplain environments. The communities located in the Amazonian floodplains are a place of rich biodiversity and culture for the riverside people who live there, in addition to great socioeconomic importance, as it is where much of the food consumed in the cities and capitals is produced. Therefore, studies related to these agroecosystems are essential for their better understanding and for public policies to be created and implemented in order to more assertively contemplate the social subjects who live and exercise their territoriality in these locations. O presente trabalho apresenta uma vasta pesquisa bibliogr??fica que, aliada ?? pesquisa in loco possibilitou a processo de seu artesanato intelectual. Foram utilizadas ferramentas adaptadas e adequadas ?? realidade dos envolvidos na pesquisa de campo, sendo elas, entrevistas abertas e formul??rios com quest??es pertinentes ao tema, bem como, ??s categorias de an??lise escolhidas para um melhor entendimento da gest??o do territ??rio na Comunidade S??o Francisco. Com isso, gest??o territorial, agroecossistemas e governan??a foram as 03 (tr??s) categorias de an??lise que nortearam a pesquisa e contribu??ram para o alcance de seu objetivo geral que foi analisar a gest??o territorial na Comunidade S??o Francisco no munic??pio do Careiro da V??rzea (AM), e tamb??m o alcance dos objetivos espec??ficos, que se desdobraram em 03 (tr??s) cap??tulos, cada um abordou quest??es essenciais para a elucida????o de como acontece a gest??o territorial na ??rea de estudo. Estudos em rela????o ?? gest??o de territ??rios est??o presentes na academia, por??m poucos voltados ?? realidade amaz??nica dos ambientes varzeanos. As comunidades localizadas nas v??rzeas amaz??nicas, s??o lugar de rica biodiversidade e cultura por parte dos ribeirinhos que nela habitam, al??m de uma grande import??ncia socioecon??mica, pois ?? onde se produz grande parte dos alimentos consumidos nas sedes dos munic??pios e nas capitais. Sendo assim, estudos referentes a estes agroecossistemas s??o essenciais para seu melhor entendimento e para que pol??ticas p??blicas sejam criadas e executadas de forma a contemplar de maneira mais assertiva os sujeitos sociais que vivem e exercem sua territorialidade nessas localidades.

However, the forest has been suffering major interference and changes in its natural structure through the advance and agricultural expansion in the Amazon region arising from anthropic practices, which has resulted in degradation, loss of soil quality and the sustainability of production environments. The objective of this work was to evaluate the physical quality of the soil under agricultural activity in the southern region of Amazonas, aiming to investigate the impacts arising from agricultural practices currently used by rural producers in the municipality of Humait??-AM, using as indicators the physical attributes and the stock of carbon (EC) of soils. The study was carried out in the rural area of Humait??-AM, in four different environments, being the cultivation of a??a??, manioc, pasture and a forest area in three depths 0.00-0.05, 0.05-0.10 and 0.10-0.20 m, totaling 120 samples, collection was performed at 10 points in each studied area. The physical attributes evaluated were: textural analysis of sand, silt and clay fractions, soil density (Sd), weighted mean diameter (WPD), geometric mean diameter (WGD), soil penetration resistance (RSP), aggregate class < 1.00 mm, 1.00 ??? 2.00 mm and > 2.00 mm, total porosity (Tp), macroporosity (MaP), microporosity (MiP), gravimetric moisture (GM), soil organic carbon were also determined (COS), organic matter (OM) and soil carbon stock (EC). After the laboratory analysis of the attributes, tests of descriptive statistics were carried out and the means were compared by the Tukey test at 5% of probability, later, a multivariate analysis was carried out using the technique of analysis of principal components. According to the results obtained, it is concluded that the conversion of the forest area into agricultural use environments caused changes in soil attributes. A regi??o Amaz??nica tem atra??do cada vez mais a aten????o de pesquisadores devido a vasta riqueza de diversidade desse bioma, composi????o e estruturas complexas do solo. Entretanto a floresta vem sofrendo grandes interfer??ncias e modifica????es em sua estrutura natural mediante ao avan??o e expans??o agropecu??ria na regi??o Amaz??nica oriundos de pr??ticas antr??picas, que vem resultando na degrada????o, perda da qualidade do solo e a sustentabilidade dos ambientes de produ????o. O objetivo desse trabalho foi avaliar a qualidade f??sica do solo sob atividade agropecu??ria na regi??o Sul do Amazonas, visando investigar os impactos oriundos das pr??ticas agropecu??rias utilizadas atualmente pelos produtores rurais no munic??pio de Humait??-AM, utilizando como indicadores os atributos f??sicos e o estoque de carbono (EC) dos solos. O estudo foi realizado na zona rural de Humait??-AM, em quatro ambientes diferentes, sendo eles o cultivo de a??a??, mandioca, pastagem e uma ??rea de floresta em tr??s profundidades 0,00-0,05, 0,05-0,10 e 0,10-0,20 m, totalizando 120 amostras, a coleta foi realizada em 10 pontos de cada ??rea estudada. Os atributos f??sicos avaliados foram: an??lise textural das fra????es areia, silte e argila, densidade do solo (Ds), di??metro m??dio ponderado (DMP), di??metro m??dio geom??trico (DMG), resist??ncia do solo a penetra????o (RSP), classe de agregados < 1,00 mm, 1,00 ??? 2,00 mm e > 2,00 mm, porosidade total (Pt), macroporosidade (MaP), microporosidade (MiP), umidade gravim??trica (Ug), tamb??m foram determinados o carbono org??nico do solo (COS), mat??ria org??nica (MO) e estoque de carbono do solo (EC). Ap??s as an??lises laboratoriais dos atributos foram realizados testes de estat??stica descritiva e as m??dias comparadas pelo teste de Tukey a 5% de probabilidade, posteriormente foi realizada an??lise multivariada utilizando a t??cnica de an??lise de componentes principais. De acordo com os resultados obtidos, conclui-se que a convers??o da ??rea de floresta em ambientes de uso agropecu??rios ocasionou mudan??as nos atributos dos solos.

Pesquisa do Estado do Amazonas CAPES - Coordena????o de Aperfei??oamento de Pessoal de N??vel Superior The Amazonian riverside populations follow the rhythm of the hydrological cycle of the rivers: flood, flood, ebb and dry. They have adequate adaptability to these changes and are able, to some extent, to know whether the ebb and flow period will be extraordinary and whether there is a need to change or adopt protective measures in the face of these changes. However, in the past 30 years, episodes of floods and ebbs have become increasingly intense and frequent in the Amazon. The Madeira River basin has been experiencing an increase in the frequency of these events, in a very short period of time, highlighting the most recent of severe ebbs, in 2005 and 2010 and extreme floods, in 2008 and 2014. In this thesis, these events are called extreme hydrological events. They are felt by the riverside populations, especially regarding the amount of sediment that is deposited in the areas occupied by the communities and that is revealed in the post-flood, making the residents unable to carry out social, agricultural, fishing, extractive activities, activities, navigation and access to health and education services. The main objective of the present study was to verify the relationship of the inhabitants' perception about extreme hydrological events and the possible changes in the adaptive strategies of four riverside communities of the Rio Madeira Sustainable Development Reserve. To achieve the expected result, we sought to investigate the environmental perception of residents in relation to flood risks and their consequences, describe the impacts caused by the extreme sedimentation that occurs in the floodplain of the Madeira River Reserve and finally present the interaction network on the causes and effects on the socio-ecological systems of the studied area. Data were collected by applying a form in 2018 with twenty-four residents, in addition to the forms, key informants were interviewed, two managers and four community presidents, who are people who have deep knowledge of local particularities. Four workshops were also held, totaling the presence of fifty-four participants. According to the results obtained, it was found that the individuals surveyed perceive the influence of extreme hydrological events of flood and ebb in the last three decades, recognizing that such events directly affect not only economic activities, such as agriculture and fishing mainly, but also, the routine tasks of day-to-day and the special ones that make up the social life of families. It was also found that the majority of those surveyed adopted measures to prevent and minimize risks and losses, such as, for example, the construction of houses at higher points and new forms of planting in the floodplain. These measures were taken after the 2014 flood, the year of the greatest flood ever recorded, which caused destruction of improvements and plantations and economic losses to residents. However, it is concluded that despite the problems suffered with events of abnormal floods and ebbs, the residents do not abandon their lands and create strategies to overcome the adversities imposed by the hydrological regime during these episodes of extreme events. As popula????es ribeirinhas amaz??nicas acompanham o ritmo do ciclo hidrol??gico dos rios: enchente, cheia, vazante e seca. Elas possuem uma adequada adaptabilidade quanto ??s essas mudan??as e s??o capazes, at?? certo ponto, de saber se o per??odo de vazante e de cheia ser?? extraordin??rio e se h?? necessidade de mudar ou adotar medidas de prote????o frente a essas mudan??as. Por??m, nos 30 ??ltimos anos, os epis??dios de cheias e vazantes t??m se tornando cada vez mais intensos e frequentes, na Amaz??nia. A bacia do rio Madeira vem experimentando um aumento na frequ??ncia desses eventos, em um per??odo muito curto, destacando os mais recentes de vazante severas, em 2005 e 2010 e de cheias extremas, em 2008 e 2014. Nesta tese, estes eventos s??o denominados de eventos hidrol??gicos extremos. Eles s??o sentidos pelas popula????es ribeirinhas, principalmente no que diz respeito ?? quantidade de sedimentos que ?? depositada nas ??reas ocupadas pelas comunidades e que se revela na p??s-enchente, tanto o deposito de sedimento quanto a seca severa e a cheia extrema faz com que os moradores fiquem impossibilitados de realizar atividades sociais, agr??colas, pesqueiras, extrativistas, navega????o e de terem acesso aos servi??os de sa??de e de educa????o. O objetivo principal do presente estudo foi verificar a rela????o da percep????o dos habitantes sobre os eventos hidrol??gicos extremos e as poss??veis mudan??as nas estrat??gias adaptativas de 4 comunidades ribeirinhas da Reserva de Desenvolvimento Sustent??vel do Rio Madeira. Para avaliar a percep????o dos moradores buscou-se investigar a rela????o aos riscos de inunda????o e suas consequ??ncias, descrever os impactos causados pela sedimenta????o extrema que ocorre na v??rzea da RDS do Rio Madeira e por fim apresentar a rede de intera????o sobre as causas e efeitos nos sistemas socioecol??gicos da ??rea estudada. Os dados foram coletados por meio de aplica????o de formul??rio em 2018 com vinte e quatro moradores, al??m dos formul??rios foram entrevistadas informantes-chave, sendo, dois gestores e quatro presidentes de comunidades, s??o pessoas que possuem profundo conhecimento das particularidades locais. Tamb??m foram realizadas quatro oficinas totalizando a presen??a de cinquentas e quatro participantes. De acordo com os resultados obtidos, constatou???se que os indiv??duos pesquisados percebem a influ??ncia dos eventos hidrol??gicos extremos de cheia e vazante nas ??ltimas tr??s d??cadas, reconhecendo que tais eventos afetam diretamente n??o somente as atividades econ??micas, como a agricultura e a pesca, mas tamb??m, as tarefas rotineiras do dia-a-dia que comp??em a vida social das fam??lias. Verificou???se que a maioria dos pesquisados adota medidas de preven????o e de minimiza????o dos riscos e perdas, como por exemplo, a constru????o de casas em pontos mais alto e novas formas de plantio na v??rzea. Essas medidas foram tomadas ap??s a enchente de 2014, ano da maior cheia j?? registrada e que causou destrui????es de benfeitorias, plantios e preju??zos econ??micos aos moradores.

Pesquisa do Estado do Amazonas Climatic situations may undergo some changes due to vegetation cover, urbanization, agriculture and livestock activities, among others. The municipality of Humait?? has been experiencing growth in several sectors in recent years and this brings a reflection on how some environmental situations have been planned, as it directly and/or indirectly can cause human beings to vary in environmental thermal comfort. The present work gathered a five-year database, encompassing climatological variables, relative humidity, precipitation and air temperature in order to analyze their variation in this period, calculate their values and apply them in equations that define the level of human comfort and/or discomfort for the population. The objective was to study how different occupations of space in the urban area influence the behavior of climatological variables int the municipality of Humait??-AM, aiming to understand how this interaction acts under the external environmental thermal comfort in the routine activities of the population. Then the data were evaluated both in the dry and rainy season, in addition to proposing suggestions for urban planning and development in the environmental area that encompasses the city??s green areas. Data were collected from the Climate Data Store (CDS) which provides an ERA5 climatological dataset. The entire statistical process of data analysis was carried out in Microsoft Excel, where we obtained results of maximum and minimum values, means, standard deviation and standard error. After this step, the Thermal Discomfort Index (TDI) and the Temperature and Humidity Index (ITU) were calculated. These indices only consider situations in the external environment to define their results. The results showed us that the climatological variables had at times maximum values well above normal, however the average of these variables had a normality within the local climate of the municipality. The variation of IDT and ITU was shown in the vast majority of standardized months, the variation of their results was verified with emphasis on dry and rainy periods. Situa????es clim??ticas podem sofrer algumas altera????es devido a cobertura vegetal, urbaniza????o, atividades de agricultura e pecu??ria entre outras. O munic??pio de Humait?? passa por um crescimento em v??rios setores nos ??ltimos anos e isso traz uma reflex??o em como tem sido planejado algumas situa????es ambientais, pois a mesma de maneira direta e/ou indiretamente pode causar ao ser humano uma varia????o do conforto t??rmico ambiental. O presente trabalho, reuniu um banco de dados de cinco anos, englobando as vari??veis climatol??gicas, umidade relativa do ar, precipita????o e a temperatura do ar com o intuito de analisar sua varia????o nesse per??odo, calcular seus valores e aplicar os mesmos em equa????es que definem o n??vel do conforto e/ou desconforto humano para a popula????o. O objetivo foi de estudar como diferentes ocupa????es do espa??o na ??rea urbana, influenciam o comportamento das vari??veis climatol??gicas no munic??pio de Humait??-AM, visando entender como esta intera????o age sob o conforto t??rmico ambiental externo nas atividades de rotina da popula????o. Logo os dados foram avaliados tanto no per??odo seco como chuvoso, al??m de propor sugest??es para o planejamento e desenvolvimento urbano na ??rea ambiental que engloba as ??reas verdes da cidade. Os dados foram coletados no Climate Data Store (CDS) que fornece uma s??rie de dados climatol??gicos ERA5. Todo o processo estat??stico de an??lise dos dados foi feito no Microsoft Excel, onde obtivemos resultados de valores m??ximos e m??nimos, m??dias, desvio padr??o e erro padr??o. Ap??s essa etapa foi calculado o ??ndice de Desconforto T??rmico (IDT) e o ??ndice de Temperatura e Umidade (ITU). Esses ??ndices consideram apenas situa????es do meio ambiente externo para definir seus resultados. Os resultados nos mostraram que as vari??veis climatol??gicas tiveram em alguns momentos valores m??ximos bem acima do normal, entretanto a m??dia dessas vari??veis teve uma normalidade dentro do clima local do munic??pio. A varia????o do IDT e ITU se mostrou na grande maioria dos meses padronizadas, a varia????o dos seus resultados foi verificada com ??nfase nos per??odos secos e chuvosos.

Worldwide, several researches are being carried out in the search for new sources of enzymes that can meet the needs of the cheese market. Based on the industrial importance of fungi, this study aimed to evaluate species of the genus Aspergillus to select a strain that produces coagulant enzymes from bovine milk and to investigate regulatory mechanisms of coagulant synthesis to identify characteristics for industrial application. The strains: A. clavato flavus DPUA 929, A. fischeri DPUA 653, A. flavo furcatis DPUA 1451, A. flavo furcatis DPUA 1455, A. japonicus DPUA 542, A. japonicus DPUA 1727, A. melleus DPUA 323, A. niger DPUA 398, A. niger DPUA 399, A. ostianus DPUA 315, A. oryzae DPUA 541, A. oryzae DPUA 1624 and A. wentii DPUA 1725, are the 13 representatives of the genus Aspergillus. In the first step, the lines were authenticated based on macromorphological and micromorphological characteristics. Pure and viable cultures were used in the selection of a species that produced proteases and coagulants by submerged fermentation under standardized conditions. The enzyme extract recovered from fermentation was used to determine the activity of proteases and later partial characterization regarding the effect of pH and temperature on the activity and stability and effect of metal ions and inhibitors on the enzyme activity. And to identify the nutritional requirements, they were selected as a source of carbon, starch and as a source of nitrogen, casein, associated with three different incubation times, and for the synthesis of coagulants by Aspergillus, in a complete factorial design 23 , with 3 central points, totaling 11 experiments. The extract with the highest coagulant ratio was characterized as to the effect of pH and temperature on enzyme activity and stability. The effect of inhibitors and metal ions on clotting activity was also evaluated, in addition to the evaluation of in vitro cytotoxicity using human fibroblasts. Most of the tested strains produced proteases in liquid medium. Aspergillus flavo furcatis DPUA 1451 was identified as a significant source of serine proteases and metalloproteases that express significant catalytic activity at pH 5.0 and 50 ??C, with stability at pH 7 to 9, up to 40 ??C, in 60 minutes, which demonstrates the potential use of these biocatalysts in the food industry, mainly for cheese production. O coalho extra??do de bezerro, fonte de coagulantes do leite bovino, nos ??ltimos anos n??o atende as exig??ncias de alguns grupos de consumidores, devido a diversas causas, como a mudan??a de h??bitos alimentares e cren??as religiosas. Mundialmente, diversas pesquisas est??o sendo desenvolvidas na busca por novas fontes de enzimas que possam suprir a necessidade do mercado de queijos. Com base na import??ncia industrial dos fungos, este estudo teve como objetivo avaliar esp??cies do g??nero Aspergillus para selecionar uma linhagem produtora de enzimas coagulantes do leite bovino e investigar mecanismos regulat??rios de s??ntese dos coagulantes para identifica????o das caracter??sticas para aplica????o industrial. As linhagens: A. clavato flavus DPUA 929, A. fischeri DPUA 653, A. flavo furcatis DPUA 1451, A. flavo furcatis DPUA 1455, A. japonicus DPUA 542, A. japonicus DPUA 1727, A. melleus DPUA 323, A. niger DPUA 398, A. niger DPUA 399, A. ostianus DPUA 315, A. oryzae DPUA 541, A. oryzae DPUA 1624 e A. wentii DPUA 1725, s??o os 13 representantes do g??nero Aspergillus. Na primeira etapa, as linhagens foram autenticadas com base nas caracter??sticas macromorfol??gicas e micromorfol??gicas. As culturas puras e vi??veis foram utilizadas na sele????o de uma esp??cie produtora de proteases e coagulantes por fermenta????o submersa, em condi????es padronizadas. O extrato enzim??tico recuperado da fermenta????o foi utilizado para determina????o da atividade das proteases e posterior caracteriza????o parcial quanto ao efeito do pH e temperatura na atividade e estabilidade e efeito de ??ons met??licos e inibidores na atividade enzim??tica. E para identifica????o das exig??ncias nutricionais, foram selecionadas como fonte de carbono, amido e como fonte de nitrog??nio, case??na, associados a tr??s diferentes tempos de incuba????o, e para a s??ntese dos coagulantes por Aspergillus, em planejamento fatorial completo 2 3 , com 3 pontos centrais, totalizando 11 experimentos. O extrato com maior raz??o coagulante foi caracterizado quanto ao efeito do pH e temperatura na atividade e estabilidade enzim??tica. Tamb??m foi avaliado o efeito de inibidores e ??ons met??licos na atividade coagulante, al??m da avalia????o quanto ?? citotoxicidade in vitro utilizando fibroblastos humanos. A maioria das linhagens testadas produziram proteases em meio l??quido. Aspergillus flavo furcatis DPUA 1451 foi identificada como fonte significativa de serinoproteases e metaloproteases que expressam atividade catal??tica significativa em pH 5,0 e 50 ??C, com estabilidade em pH 7 a 9, at?? 40 ??C, em 60 minutos, o que demonstra o uso potencial destes biocatalisadores na ind??stria de alimentos, principalmente para a produ????o de queijos.

In contrast to Environmental Economics, Ecological Economics refutes the hypothesis that technological advances can offer solutions in an undetermined way to the limits that the environment offers to economic growth. In addition to the traditional dilemma about compatibility between the economy and the environment, the health problems to which the populations of large cities are exposed are added due to how much and how anthropic processes are expanding in large urban centers, such as the case of Manaus. The hypothesis is that sources of particulate matter present in the city, such as: the vehicle fleet, the generation of fossil fuel-based thermoelectric energy, the refining of oil and the number of burnings influence the number of hospitalizations due to respiratory problems in the city. Based on this triad: Economy, Environment and Health, this research aimed to: (i) analyze how the main anthropic air pollution actions evolved in Manaus; (ii) estimate the amount of annual particulate matter emission from the main potentially polluting urban industrial activities in the years 2014 to 2019 and; (iii) verify if the concentration of particulate matter in the atmosphere of Manaus were associated with the number of hospitalizations due to respiratory problems in the city in the period from 2008 to 2019. To this, a historical review was made of the transition process of the capital's energy matrix, the characterization of the quantity and composition of the fleet, the quantification and description of the characteristics of the refining process in Manaus. The particulate matter emission inventory was made based on estimates based on the method of using emission factors, which represent an average emission of pollutants from different sources. Finally, Linear Models, Generalized Linear Models and Generalized Additive Models were tested to verify the best fit to verify if there was an association between the concentration of particulate matter in the atmosphere and the number of hospitalizations in Manaus, as well as, if there was an association between the evolution of human activities and the number of hospitalizations for respiratory diseases in the period from 2008 to 2019. It was found that the generation of thermoelectric energy was the main source of emission of particulate material in Manaus during almost the entire period analyzed, but with successive and significant reductions from the introduction of natural gas in the city's energy matrix. In the last year of the series, the main source of emission of particulate matter in Manaus was the vehicle fleet, a trend consistent with large urban centers in Brazil and the world. Regarding hospitalizations, generalized additive models with Poisson regression, with smoothing curves for seasonality adjustments due to climatic factors and months and years indicators, showed the most consistent results. It was not possible to establish an association between the concentration of PM2.5 and the number of hospitalizations, neither by the total nor by the number of occurrences by age groups. These episodes seem to be better explained by cases of Influenza, whose seasonality peaks in the rainy months in the Amazon. However, the GAM model showed a strong association between the intensity of the generation of thermoelectric energy, the vehicle fleet, the quantity of fires and the concentration of PM2.5 itself, which may indicate that another atmospheric pollutant resulting from urban economic activity may influence hospital visits for respiratory problems in the city of Manaus. The absence of observational data on the characterization of the vehicle fleet and the concentration of pollutants in the atmosphere of Manaus, may represent some kind of weakness in the results presented. O avan??o do debate acerca da quest??o ambiental reorientou a teoria econ??mica tradicional, no sentido de comportar na base anal??tica da Teoria Neocl??ssica o problema da escassez dos bens e servi??os ecossist??micos. Em contraponto ?? Economia Ambiental, a Economia Ecol??gica refuta a hip??tese de que o avan??o tecnol??gico possa oferecer solu????es de forma indeterminada aos limites que o meio ambiente oferece ao crescimento econ??mico. Ao dilema tradicional que h?? entre compatibiliza????o entre economia e meio ambiente, acrescentam-se os problemas de sa??de a que as popula????es das grandes cidades est??o expostas em virtude do quanto e de como os processos antr??picos est??o se expandindo nos grandes centros urbanos, como ?? o caso de Manaus. A hip??tese ?? a de que fontes de material particulado presentes na cidade, tais como: a frota de ve??culos, a gera????o de energia termel??trica baseada em combust??veis f??sseis, o refino de petr??leo e a quantidade de queimadas influenciam a quantidade de internamentos por problemas respirat??rios na cidade. Com base nessa tr??ade: Economia, Meio Ambiente e Sa??de, esta pesquisa teve como objetivos: (i) analisar o modo como as principais a????es antr??picas de polui????o do ar evolu??ram em Manaus; (ii) estimar o montante de emiss??o de material particulado anual das principais atividades industriais urbanas potencialmente poluidoras nos anos de 2014 a 2019 e; (iii) verificar se a concentra????o de material particulado na atmosfera de Manaus esteve associada ?? quantidade de internamentos por problemas respirat??rios na cidade no per??odo de 2008 a 2019. Para tanto, foi feito um resgate hist??rico do processo de transi????o da matriz energ??tica da capital, a caracteriza????o da quantidade e da composi????o da frota, a quantifica????o e a descri????o das caracter??sticas do processo de refino em Manaus. O invent??rio de emiss??o de material particulado foi feito a partir de estimativas baseadas no m??todo de utiliza????o de fatores de emiss??o, que representam uma m??dia de emiss??o de poluentes de diversas fontes. Por fim, foram testados Modelos Lineares, Modelos Generalizados Lineares e Modelos Aditivos Generalizados para verificar qual o melhor ajuste para verificar se houve associa????o entre a concentra????o de material particulado na atmosfera e o n??mero de internamentos em Manaus, bem como, se havia associa????o entre a evolu????o das atividades antr??picas e o n??mero de internamentos por doen??as respirat??rias no per??odo de 2008 a 2019. Verificou-se que a gera????o de energia termel??trica foi a principal fonte de emiss??o de material particulado em Manaus durante quase todo o per??odo analisado, mas com sucessivas e expressivas redu????es a partir da introdu????o do g??s natural na matriz energ??tica da cidade. No ??ltimo ano da s??rie, a principal fonte de emiss??o de material particulado em Manaus foi a frota de ve??culos, uma tend??ncia condizente com grandes centros urbanos do Brasil e do mundo. Relativamente aos internamentos, os modelos aditivos generalizados com regress??o de Poisson, com curvas de suaviza????o de ajustes de sazonalidade por fatores clim??ticos e indicadores de meses e anos, foi o que apresentou resultados mais consistentes. N??o foi poss??vel estabelecer associa????o entre concentra????o de PM2,5 e quantidade de internamentos, nem pelo total, nem pela quantidade de ocorr??ncias por faixas et??rias. Estes epis??dios parecem ser melhor explicados por casos de Influenza, cuja sazonalidade apresenta picos nos meses de chuva na Amaz??nia. No entanto, o modelo GAM apresentou forte associa????o entre a intensidade da gera????o de energia termel??trica, da frota de ve??culos, da quantidade de queimadas e da pr??pria concentra????o de PM2,5, o que pode indicar que outro poluente atmosf??rico fruto da atividade econ??mica urbana pode influenciar em atendimentos hospitalares por problemas respirat??rios na cidade de Manaus. A aus??ncia de dados observacionais relativos ?? caracteriza????o da frota de ve??culos e da concentra????o de poluentes na atmosfera de Manaus, podem representar algum tipo de fragilidade nos resultados apresentados.

The application detects and characterizes elements of nature using Artificial Intelligence technologies. To achieve the objective, classes were taught adopting active teaching-learning methodologies for the research subjects. The performances took place with the students of the technical course in computer science at the Federal Institute of Amazonas on the campuses of the municipalities of S??o Gabriel da Cachoeira and Mau??s. The content discussions were based on Paulo Freire's praxis, in which theory and practice come together to develop in the student a process of emancipatory transformation based on reflection-action- reflection. Because of the environmental context in which most students were inserted, the generator theme chosen was Amazonian flora. The classes took place in phases and in different disciplines whose results added to the tutorial content. Interviews were conducted via form with open and closed questions to be able to analyze the effects of the experiences lived by the students. The resulting educational product contributes to the improvement of practices and the educational praxis of teachers from different areas of knowledge, as well as making them rethink lesson plans with the themes of environmental sciences mediated by Digital Information and Communication Technologies. O conte??do dessa disserta????o ?? sobre um projeto de atua????o docente que teve como objetivo desenvolver um tutorial de aulas pr??ticas usando um aplicativo como colaborador da pr??xis pedag??gica para discuss??o de temas ambientais. O aplicativo detecta e caracteriza elementos da natureza utilizando tecnologias de Intelig??ncia Artificial. Para atingir o objetivo, foram ministradas aulas adotando metodologias ativas de ensino-aprendizagem para os sujeitos da pesquisa. As atua????es ocorreram com os discentes do curso t??cnico em inform??tica do Instituto Federal do Amazonas nos campi dos munic??pios de S??o Gabriel da Cachoeira e de Mau??s. As discuss??es dos conte??dos foram baseadas na pr??xis de Paulo Freire, em que teoria e pr??tica se juntam para desenvolver no estudante um processo de transforma????o emancipat??ria a partir da reflex??o-a????o-reflex??o. Por causa do contexto ambiental em que a maioria dos estudantes estavam inseridos, o tema gerador escolhido foi a flora amaz??nica. As aulas ocorreram em fases e em disciplinas distintas cujos resultados agregaram ao conte??do do tutorial. Foram realizadas entrevistas via formul??rio com perguntas abertas e fechadas para ser poss??vel analisar os efeitos das experi??ncias vivenciadas pelos discentes. O produto educacional resultante contribui na melhoria das pr??ticas e a pr??xis educativa de docentes das diversas ??reas do conhecimento, bem como faz??-los repensar planos de aula com as tem??ticas das ci??ncias ambientais mediadas por Tecnologias Digitais de Informa????o e Comunica????o.

Pesquisa do Estado do Amazonas The theme of this research is teacher training. The main objective was to produce a relational analytical theoretical framework among aspects that enable the construction of pedagogical competences and professional teaching autonomy in courses of initial formation of teachers of Chemistry. It is a research with a qualitative approach, the research participants were 16 Chemistry graduates. This research is in line with the training of science and mathematics teachers, more precisely with respect to the initial training of teachers of chemistry. The instruments used for data collection were: document analysis of the 2005 and 2016 PPCs; semi structured interview and questionnaire. The technique used in the analysis of the interviews, PPCs and open questions of the questionnaire was ATD, and for the closed questions of the questionnaires we used descriptive statistics that involved the calculation of Fashion, Average Ranking (RM) and Total Score. We point out as main results the challenges of maintaining the coherence between the prescribed curriculum and the profile of the graduates and the contradictions that appear around the teaching of the contents and the perception of the Chemistry graduates about the autonomy. In conclusion, we point out some knowledge gaps, such as: Why or what reasons for the present contradiction in the understanding of autonomy? Are there possible ways to change the perception of undergraduates that teaching is not depositing as much content as possible? How to resolve the effects of this traditional teaching vision on initial training? O tema dessa pesquisa ?? autonomia na forma????o de professores. O objetivo principal foi produzir um quadro te??rico anal??tico relacional entre aspectos que possibilitam a constru????o de compet??ncias pedag??gicas e autonomia profissional docente em cursos de forma????o inicial de professores de Qu??mica. Trata-se de uma pesquisa com abordagem qualitativa, os participantes da pesquisa foram 16 licenciandos de Qu??mica. Essa pesquisa situa-se na linha de forma????o de professores de ci??ncias e matem??tica, mais precisamente com respeito a forma????o inicial de professores de Qu??mica. Os instrumentos utilizados para coleta de dados foram: an??lise documental dos PPCs de 2005 e 2016; entrevista semiestruturada e question??rio. A t??cnica utilizada na an??lise das entrevistas, PPCs e quest??es abertas do question??rio foi ATD, e para as quest??es fechadas dos question??rios usamos estat??stica descritiva que envolveu o c??lculo da Moda, Ranking M??dio (RM) e Escore Total. Apontamos como principais resultados os desafios de manter a coer??ncia entre o curr??culo prescrito e o perfil dos licenciandos e as contradi????es que figuram em torno do ensino dos conte??dos e a percep????o dos licenciandos de Qu??mica acerca da autonomia. A modo de conclus??o, apontamos algumas lacunas de conhecimento, como por exemplo: Por que ou quais raz??es para a contrariedade presente no entendimento da autonomia? Existem meios poss??veis para mudar a percep????o dos licenciandos de que ensinar n??o ?? depositar o m??ximo de conte??do? Como dirimir os efeitos dessa vis??o tradicional de ensino na forma????o inicial? Sugiro que a????es institucionais como estas sejam divulgadas. Gostaria de agradecer aos funcion??rios da biblioteca da Faculdade de Direito - Ufam por me ajudarem na formula????o de buscas sistem??ticas.

Studies carried out in the Amazon Region indicate the presence of active substances such as flavonoids, terpenes, saponins and alkaloids in the bark and heartwood of species of the family. The phytochemical prospecting aimed to identify groups of secondary metabolites present in the crude extract and fractions of the D. racemosa bark, whose chemical constitution is unknown. The peel was dried, crushed and the crude extract was obtained under reflux with 70% ethanol. The crude extract was fractionated by liquid-liquid partition, obtaining the following fractions: hexane, chloroform, ethyl acetate, butanolic and hydroalcoholic. The chemical constitution of the extracts was evaluated before reaction in tubes and chromatographic plates. The antioxidant activity was analyzed against the radicals DPPH and ABTS, and the content of total phenols was determined. The butanolic fraction was fractionated in the HPCCC using solvent systems composed of: ethyl acetate - butanol - water. Chromatographic and spectroscopic methods were used to obtain the chemical profile of the purified samples. Phytochemical prospecting showed qualitatively the presence of the following classes of secondary metabolites: condensed tannins, flavones, flavonoids, xanthones, flavanone, flavanones, pentacyclic triterpenes, saponins and alkaloids. CCD analysis showed the presence of flavonoids in the following samples: crude extract, ethyl acetate fraction and butanolic fraction. In addition, it allowed to monitor the entire process of isolation and antioxidant activity against DPPH, which in the in vitro assay the ethyl acetate fraction showed an IC50 of 49.27 ??g / mL and a higher concentration of total phenols. However, the fraction yield in ethyl acetate was low, so the isolation was directed to the second most active fraction, considering the antioxidant test of ABTS. The HPCCC technique allowed for fast and effective targeting for the fractionation and purification of substances. In the present study, it was possible to purify and identify 4 novel C-glycosylated flavones in the species D. racemosa, namely: violantine (8.4 mg), isoviolantine (12.1 mg), vitexin (12 mg) and isovitexine (7.7 mg). This research was a pioneer in the phytochemical characterization of wood residue D. racemosa, collected in the Middle Amazon region. These results demonstrate a possibility for the use of residues by the industry, supplying substances with technological potential, contributing to the environment. This work contributes to the phytochemical knowledge of the genus Diplotropis and should be continued to find new substances present with biological potentials, yet to be explored. Diplotropis racemosa (Hoehne) pertence ?? fam??lia Leguminosae, conhecida popularmente como Sucupira preta, possui dispers??o pelo Brasil e ?? bastante utilizada em ??reas degradadas. Estudos realizados na Regi??o Amaz??nica apontam a presen??a de subst??ncias ativas como flavonoides, terpenos, saponinas e alcaloides em cascas e cernes de esp??cies da fam??lia. A prospec????o fitoqu??mica teve como objetivo a identifica????o de grupos de metab??litos secund??rios presentes no extrato bruto e fra????es da casca de D. racemosa, cuja constitui????o qu??mica ?? desconhecida. A casca foi seca, triturada e o extrato bruto foi obtido sob refluxo com etanol 70%. O extrato bruto foi fracionado por parti????o l??quido-l??quido, sendo obtidas as seguintes fra????es: hex??nica, clorof??rmica, acetato de etila, butan??lica e hidroalc??olica. A constitui????o qu??mica dos extratos foi avaliada perante rea????o em tubos e em placas cromatogr??ficas. A atividade antioxidante foi analisada frente aos radicais DPPH e ABTS, sendo determinado o teor de fen??is totais. A fra????o butan??lica foi fracionada no HPCCC utilizando sistemas de solventes compostos por: acetato de etila ??? butanol ??? ??gua. M??todos cromatogr??ficos e espectrosc??picos foram utilizados para obten????o do perfil qu??mico das amostras purificadas. A prospec????o fitoqu??mica evidenciou qualitativamente a presen??a das seguintes classes de metab??litos secund??rios: taninos condensados, flavonas, flavonois, xantonas, flavanonois, flavanonas, triterpenos pentac??clicos, saponinas e alcaloides. A an??lise por CCD evidenciou a presen??a de flavonoides nas seguintes amostras: extrato bruto, fra????o acetato de etila e fra????o butan??lica. Al??m disso, permitiu acompanhar todo o processo de isolamento e atividade antioxidante frente ao DPPH, que no ensaio in vitro a fra????o em acetato de etila apresentou uma CI50 de 49,27 ??g/mL e maior concentra????o de fen??is totais. No entanto, o rendimento da fra????o em acetato de etila foi baixo, com isso o isolamento foi direcionado para a segunda fra????o mais ativa, considerando o ensaio antioxidante de ABTS. A t??cnica de HPCCC possibilitou o direcionamento r??pido e eficaz para o fracionamento e purifica????o das subst??ncias. No presente estudo foi poss??vel purificar e identificar 4 flavonas C-glicosiladas in??ditas na esp??cie D. racemosa, sendo elas: violantina (8,4 mg), isoviolantina (12,1 mg), vitexina (12 mg) e isovitexina (7,7 mg). Essa pesquisa foi pioneira na caracteriza????o fitoqu??mica do res??duo madeireiro D. racemosa, coletada na regi??o do M??dio Amazonas. Estes resultados demonstram uma possibilidade para o aproveitamento dos res??duos pela ind??stria, fornecendo subst??ncias com potencial tecnol??gico, contribuindo para o meio ambiente. Este trabalho contribui para o conhecimento fitoqu??mico do g??nero Diplotropis e dever?? ser continuado para o encontro de novas subst??ncias presentes com potenciais biol??gicos, ainda a serem explorados.

Among them, the use of biodiesels replacing fossil fuels constitutes an important step towards this direction. Chemically, biodiesels are mixture of esters with long carbon chains. They can be obtained from vegetable oils or animal fats via transesterication. In this sense, the investigation on electron interaction with small esters is important which may help to the understanding of combustion of biodiesels. Despite that, to our knowledge, there are no other experimental or theoretical studies of electron collisions with such class of compounds. In the present study, we report a theoretical study on electron collisions with methyl formate. More specifically, elastic differential (DCS), integral (ICS), and momentumtransfer (MTCS) cross sections, as well as grand-total (TCS) and total absorption (TACS) cross sections for electron scattering by methyl formate were determined in the 1-500 eV energy range, using a combination of molecular complex optical potential (MCOP) and Pad?? approximant method. Do ponto de vista da conserva????o ambiental, a busca por fontes de energias renov??veis ?? certamente uma das estrat??gias mais importantes para qualquer pa??s que almeja o desenvolvimento sustent??vel. Dentre essas fontes, a utiliza????o de biocombust??veis ao inv??s de combust??veis f??sseis constitui um passo importante nessa dire????o. Quimicamente, o biodiesel ?? formado por uma mistura de ??steres de cadeias longas, podendo ser obtidos atrav??s de transesterifica????o de gorduras vegetais ou animais, por exemplo. Nesse sentido, a investiga????o da intera????o de el??trons com ??steres menores pode ser um importante passo inicial para auxiliar no entendimento do mecanismo detalhado da combust??o do biodiesel. Apesar dessa import??ncia, em meu conhecimento, n??o existia at?? o momento qualquer trabalho experimental ou te??rico sobre espalhamento de el??trons pela referida classe de compostos. Foi com o intuito de auxiliar no preenchimento dessa lacuna que o presente trabalho foi realizado. Neste foram realizado um estudo te??rico da colis??o de el??trons com a mol??cula de Formiato de Metila (HCOOCH3). Mais especificamente, foram calculadas as se????es de choque diferenciais el??sticas (SCD), integrais el??sticas (SCI), de transfer??ncia de momento (SCTM), totais (SCT) e de absor????o total (SCAT), na faixa de 1-500 eV. Os c??lculos foram efetuados a partir do uso de um potencial ??ptico complexo juntamente com o m??todo dos aproximantes de Pad??.
