OTIMIZAÇÃO DO PROCESSO DE TRATAMENTO DE EFLUENTES DE UMAINDÚSTRIA DE ALIMENTOS PARA MELHORIA DA EFICIÊNCIA E PRODUTIVIDADE
Get PDFThe impact of discharge from effluent treatment plants (ETP) into water bodies is a matter of great concern to most organizations. A series ofenvironmental legislation, norms and policies establish standards and guiding values to define the level of treatment necessary to ensure that the environmental impact caused by the disposal of treated sewage is acceptable. In this conception, the objective of this studyis to propose the optimization of the process, the increase in the efficiency of the effluent treatment plant and the reduction of expenses with chemical products. The study was carried out in a food company located in the state of Santa Catarina. By controlling the input Ph, analyzing whether it is necessary to use sodium hydroxide atthe station, and carrying out the initial test, the company will save time and optimize the process.O impacto da descarga de estações de tratamento de efluente (ETE) em corpos d'água é uma questão de grande preocupação para a maioria dasorganizações. Uma série de legislações, normas e políticas ambientais estabelecem padrões e valores orientadores para definir o nível de tratamento necessário a fim de garantir que o impacto ambiental causado pelo descarte do esgoto tratado seja aceitável. Nessa concepção, o objetivo desse estudo é a proposta de otimização do processo, o aumento da eficiência da estação de tratamento de efluente e a redução de gastos com produtos químicos. O estudo foi realizado em uma empresa de alimentos localizada, no estado de Santa Catarina. Controlando o Ph de entrada, analisando se é necessário utilizar hidróxido de sódio na estação e fazendo o teste inicial, a empresa poupara tempo e otimizará o processo
A PROBLEMÁTICA DAS MICOTOXINAS E DE SUAS INTERAÇÕES COM O PLANTIO DE ARROZ E A ÁGUA
No full textSome secondary metabolites produced by specific kinds of fungi are denominated mycotoxins. As the name suggests, they are toxins that can intoxicate animals and humans, bringing harm to health as carcinogenic, mutagenic, immunosuppressive pathogens, Besides several other characteristics. Thesemycotoxinsmay contaminate food, water and even the air. This review intent to explain the problems caused to living beings by mycotoxins, how it interacts with the environment and its diversity, in special the interactions between mycotoxins in waterand rice crop.Alguns metabólitos secundários produzidos por determinados tipos de fungossão denominados micotoxinas. Micotoxinas são toxinas passiveis de intoxicar animais eseres humanos, trazendo malefícios a saúde por serem carcinogênicos, mutagênicos, imunossupressores, além de outas características. Estas micotoxinas podem contaminaros alimentos a água e até mesmo o ar. O objetivo desta revisão bibliográfica é explanar sobre a diversidade das micotoxinas e os problemas que estas podem trazer aos seres vivos e suas interações com o meio ambiente, em especial as interações entre as micotoxinas presentes na água e o arroz nela cultivad
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
