Quality of groundwater in the endorheic basin of the Board of Martins, Maceió-AL
No full textWater is a limited natural resource, probably the only natural resource that has to do with all aspects of human civilization, from agricultural and industrial development to cultural and religious values rooted in society. It is essential to life, whether as a biochemical component of living things, as a livelihood of various plant and animal species, as a representative element of social and cultural values, and even as a factor of production of various final and intermediate consumer goods. This research brings, as its theme, the study of the groundwater quality of the endorheic basin of Tabuleiro do Martins, Maceió / AL, located in the Coastal Tablelands of Maceió domain, in the Alagoas Sedimentary Basin, where these waters are intensively exploited for human consumption. industrial. It is na endorheic basin where surface water accumulates in the depressions of the natural terrain, from which it evaporates or infiltrates the soil. The region has a tropical climate, dry humid, with low thermal amplitude and annual precipitation around 1480 mm. The recharge of aquifer systems is mainly due to the infiltration of surplus rainwater, estimated at 400 mm per year. From the lithostratigraphic units, the Barreiras, Marituba and Potion formations are explored, alone or together, when they form a single aquifer system. Among the potentially polluting activities identified in the region, the following stand out: sanitary sewage system, consisting of septic tanks and sinks; industrial liquid effluents in the area of the Governador Luiz Cavalcante Multisectoral Complex; gas stations; and the region's surface drainage system, consisting of flood damping lagoons that are also used as household and industrial wastewater receiving bodies. The hypothetical deductive method was adopted to evaluate the quality of local groundwater captured by tubular wells of the Alagoas Sanitation Company (CASAL), initially through the statistical analysis of the physical-chemical parameters determined by CASAL in 2008 and 2018, aiming at also the comparative study of the data available in this period. The spatial variability of groundwater physicochemical parameters was evaluated in order to identify areas subject to contamination, especially in regions that have economic and environmental relevance to society. It was also identified the degree of natural vulnerability of the groundwater of the endorheic basin of Tabuleiro do Martins, through the GOD model, vulnerability index based on lithology, depth to the water table and the degree of groundwater confinement. Finally, the research identified areas in the endorheic basin of Tabuleiro do Martins where there is already evidence of groundwater pollution or degradation compared
with the corresponding degree of natural vulnerability.FAPEAL - Fundação de Amparo à Pesquisa do Estado de AlagoasA água é um recurso natural limitado, provavelmente o único recurso natural que tem a ver com todos os aspectos da civilização humana, desde o desenvolvimento agrícola e industrial aos valores culturais e religiosos arraigados na sociedade. É essencial à vida, seja como componente bioquímico de seres vivos, como meio de vida de várias espécies vegetais e animais, como elemento representativo de valores sociais e culturais e até como fator de produção de vários bens de consumo final e intermediário. Esta pesquisa traz, como temática, o estudo da qualidade das águas subterrâneas da bacia endorreica do Tabuleiro do Martins,Maceió/AL, localizada no domínio dos Tabuleiros Costeiros de Maceió, na Bacia Sedimentar Alagoas, onde essas águas são intensivamente exploradas para consumo humano e industrial. Trata-se de uma bacia endorreica, onde as águas superficiais se acumulam nas depressões do terreno natural, de onde evapora ou infiltra no solo. A região possui clima tropical, subúmido seco, com baixa amplitude térmica e precipitações anuais em torno de 1480 mm. A recarga dos sistemas aquíferos se dá principalmente pela infiltração do excedente de águas pluviais,estimada em 400 mm anuais. Das unidades litoestratigráficas, são exploradas as formações Barreiras, Marituba e Poção, isoladamente ou em conjunto, quando formam um só sistema aquífero. Dentre as atividades potencialmente poluidoras identificadas na região, destacam-se: sistema de esgotamento sanitário, constituído por fossas sépticas e sumidouros; efluentes líquidos industriais na área do Polo Multissetorial Governador Luiz Cavalcante; postos de combustíveis; e o sistema de drenagem superficial da região, constituído de lagoas para amortecimento de cheias que são também utilizadas como corpos receptores de efluentes domiciliares e industriais. Foi adotado o método hipotético dedutivo para a avaliação da qualidade das águas subterrâneas locais captadas por poços tubulares da Companhia de Saneamento de Alagoas (CASAL), inicialmente através da análise estatística dos parâmetros físico-químicos determinados pela CASAL nos anos de 2008 e 2018, visando também o estudo comparativo dos dados disponíveis nesse período. Foi avaliada a variabilidade espacial dos parâmetros físico-químicos das águas subterrâneas, visando identificar áreas sujeitas à contaminação, principalmente em regiões que possuem relevância econômica e ambiental para a sociedade. Também foi identificado o grau de vulnerabilidade natural das águas subterrâneas da bacia endorreica do Tabuleiro do Martins, através do modelo GOD, índice de vulnerabilidade baseado na litologia, na profundidade até o lençol freático e no grau de confinamento da água subterrânea. Por fim, a pesquisa identificou áreas na bacia endorreica do Tabuleiro do Martins onde já há indícios de poluição ou degradação das águas subterrâneas comparando com o grau de vulnerabilidade natural correspondente
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
