lessandro Fo, Memories from Translating Catullus: Questions of Meter, Lexicon and Tone
This paper summarizes some of the theoretical and practical problems encountered while recently translating Catullus into Italian-“barbarian” meters. The author explains his choice of a metrical version and describes the metrical structure it entailed. He reflects in particular on some problems of fidelity and especially on the necessity of recreating – in the translated text – the same figures of speech used in the original text, such as recurring words, close lexical repetitions, alliterations and sound patterns. Of particular interest here are translation problems relative to Lesbia’s arrival at Allius’ house in c. 68b
POR QUE CONTINUAR LENDO PAULO FREIRE NOS DIAS DE HOJE?
No full textPaulo Freire\u27s works contribute significantly to education, and his pedagogy stands out for being an instrument of criticality. However, some criticisms fall on the author, especially with regard to the quality of Brazilian education. Thus, the aim of this research is to discuss the importance and contribution of Paulo Freire\u27s pedagogy to education, with the opinion of teachers at the center of the debate. To achieve the objective, an interview was conducted with a group of teachers. We conclude that the readings on Paulo Freire aroused a teacher subject concerned with a more humanized education and centered on dialogue, as well as with the overthrow of the educational paradigm. In short, teachers began to identify themselves differently with the profession, so that being a teacher gained new meanings.As obras de Paulo Freire contribuem de maneira relevante para a educação, e sua pedagogia se destaca por ser um instrumento de criticidade. Entretanto, algumas críticas recaem sobre o autor, principalmente no que tange à qualidade da educação brasileira. Assim, o objetivo desta pesquisa é discutir a importância e a contribuição da pedagogia de Paulo Freire para a educação, tendo no centro do debate a opinião de professores. Para atingir o objetivo, foi realizada uma entrevista com um grupo de professores. Concluímos que as leituras sobre Paulo Freire despertaram um sujeito professor preocupado com uma educação mais humanizadora e centrada no diálogo, bem como na derrubada do paradigma educacional. Em suma, os professores passaram a se identificar de modo diferente com a profissão, de modo que ser professor ganhou novos significados.
 
Measuring redundancy and its effect on resiliency analysis of a water distribution network
No full textWater distribution networks (WDN) are expected to perform its function even after seismic events as its service is essential, not only in keeping the welfare of the consumers, but also in performing disaster risk and management, and emergency operations. Hence, it is important that its service is uninterrupted even during and after a seismic event. To ensure uninterrupted service, WDN must adhere to resilient quality and standards. However, measuring the performance of WDN also poses a challenge as the structure of nodes and links that are interconnected, yet, responding independently to hazards.
As observed in developed countries, water distribution networks adhere to resiliency parameters such as robustness, redundancy, resourcefulness, and rapidity. Though no specific resiliency parameters are in place, several guidelines are established by the American Lifeline Alliance (ALA) and Japan Water Works Association (JWWA). For rank A facilities (such as main water distribution, transmission lines, distribution main lines), JWWA sets no light damage; or with light damage but functional; to light damage and may not be functional but can quickly recover its service as its target performance. ALA, on the other hand, sets low rate damage throughout the water system ensuring 90% of customers recover its water service within three days from a seismic event damage, and an amount of damage of 0.03 to 0.06 breaks per 1000 feet for 6-inch diameter pipes as its target performance.
Researchers, engineers, and field experts are also pushing for resilient water networks. Frameworks on resiliency and methodologies were presented to aid in quantifying the resiliency of water infrastructures. However, there is still a gap in measuring resiliency based on a framework that considered resiliency to be defined by robustness, redundancy, rapidity, and resourcefulness (4Rs). Though many have established resiliency quantification considering robustness, rapidity, and resourcefulness, there is a limited methodology that considers redundancy and its influence on WDN resiliency. It is critically important to include the influence of redundancy in WDN’s resiliency as the availability of a backup system can help ensure the continuity of functionality. Hence, this study focuses on measuring resiliency considering all 4Rs with emphasis on the influence of redundancy on it. Moreover, there is also a need for a continuous search for a tool to measure redundancy, as existing tools were shown to be not sensitive to parameters known to highly influence redundancy such as pipe capacity, number of alternative paths, and sources.
This study aimed to contribute in quantifying resiliency in water distribution networks by developing a novel method to measure resiliency. The method incorporates all 4Rs (i.e. robustness, redundancy, rapidity, and resourcefulness) in the resiliency quantification. Available tools are employed to measure robustness (e.g. PSHA, measurement of critical damage rate), rapidity (e.g. minimum spanning tree, and maximum slope method), and resourcefulness (accomplished through a survey). However, in measuring redundancy, due to the shortcoming of existing tools, a method is proposed to measure redundancy. The method involves measuring the probability of relative isolation of a demand node from a source node as links (or pipes) may
fail during a seismic event and the chance of maintaining connectivity is influenced by the backup capacity or alternative paths. Similarly, since resiliency quantification based on existing tools excludes redundancy, this study proposed a tool to measure resiliency with effects due to redundancy considered. Hence, a resiliency quantification that includes robustness, rapidity, resourcefulness, and redundancy can now be utilized as an output of this study.
The redundancy analysis, utilizing the method developed, was applied to 3 case study areas. It was shown that redundancy is highly influenced by the performance of links. Link’s performance (pipe capacity), expressed in terms of probability of failure, determines whether a path that leads to a node (connecting it from a source) may fail or not, rendering the node isolated if it fails. Another factor that affects redundancy is the availability of alternative paths, and strategic placement of additional source. Analysis results, however, showed that number of paths and links, are not as strongly as pipe capacity’s influence to connectivity.
Resiliency analysis was performed utilizing the method developed by the author/s that incorporates robustness, redundancy, rapidity, and resourcefulness. It was shown that better redundancy performance greatly improves the resiliency performance of a water distribution network as characterized by a resiliency index. Through the developed method to measure resiliency via resiliency index, it was shown that water distribution networks with good redundancy feature can improve the resiliency index of a water distribution network
Organic Acids in Aquaculture: A Bibliometric Analysis
No full textFish production faces various challenges throughout its cycle, from rearing to consumption. Organic acids have emerged as an effective fish feed and meat treatment solution. They promote health and well-being, control pathogens, improve digestion, and contribute to food preservation. This study was therefore carried out to evaluate the evolution of publications on the use of organic acids in aquaculture over time, identifying the leading journals, authors, countries, and relevant organizations associated with the publications and determining the keywords most used in publications and research trends on this type of accommodation using bibliometric analysis. For this analysis, the Web of Science (WoS) and Scopus databases were used, with the keywords and Boolean operators “organic acid*” AND (“pathogens” OR “microorganism*” OR “bacteria” OR “fungi”) AND (“fish” OR “fry” OR “pisciculture”). Ninety-six articles were found in 44 journals, with the participation of 426 authors and 188 institutions, from 1995 to 2024. The most crucial publication source with the highest impact factor was the journal Aquaculture, with 14 articles, 2 of which were written by the most relevant author, Koh C., who received the highest number of citations and had the highest impact factor among the 426 authors. China had the most scientific production, with 26 publications on organic acids in aquaculture. However, Malaysia was the country that published the most cited documents, a total of 386. The most relevant affiliation was the University of Sains Malaysia, which participated in the publication of eight articles. The 10 most frequent keywords were fish, organic acids, citric acid, article, bacteria, growth, microorganisms, Oncorhynchus mykiss, animals, and digestibility. The results indicate increased publications on the benefits of using organic acids in aquaculture, highlighting their effectiveness as antibacterial agents and promoters of zootechnical development. However, gaps still require more in-depth research into the ideal dosages, mechanisms of action, and long-term impacts of these compounds
The GEOTRACES Intermediate Data Product 2017
No full textThe GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 22 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017
