This study aims to assess the pore water movement in the tidal flat induced by tidal and thermal environment in the shallow sea. The pore water movement occurs in the tidal flat area due to the tidal effects and the presence of the biogenic gas in the tidal mud. The time lag to reach peak pore water pressure in the tidal flat area causes some upward and downward movement of the pore water during flood tide and the ebb tide. The diurnal and seasonal variation of temperature in the tidal flat area causes a movement of pore water at different depths. A correlation is developed for the temperature profile with depth in the muddy tidal flat area. The temperature distribution in the tidal mud area shows a great variation from winter to summer. The uppermost region of the tidal flat mud is largely influenced by the solar radiation. But in the deeper part, the temperature is influenced by the thermal properties of the mud, more specifically, the volumetric heat capacity of the mud.The thermal properties of the mud of the acid contaminated Ariake Sea was investigated through laboratory studies. The thermal properties of mud collected from tidal flat showed a different trend from the mud collected from under the sea due to its exposure to sunlight and the tidal wave turbulation. Thermal diffusivity does not change at all in the deep sea mud samples which typical value of 0.12 mm2/sec in all seasons. ThThe sulphide content showed peak values at the same depth where the volumetric heat capacity showed similar peak values as the sulphate reducing bacteria prosper in the layer where the volumetric heat capacity is higher. The higher volumetric heat capacity region is more stable condition which is conducive to the sulphate reducing bacteria. A modification is proposed for the sulphide content-depth distribution relationship which is primarily proposed by the Jorgensen and Sorensen. The geoenvironmental condition of the Ariake Sea has been deteriorated due to the acid treatment practice for the sea laver cultivators. Th
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Composting barrel for sustainable organic waste management in Bangladesh
To ensure quick and uniform aerobic stabilization of biowaste through domestic composting and to prevent malodorous emissions, two modifications were made to a conventional steel barrel composter by: (1) providing 0.0125 m diameter openings throughout the sides and (2) placing a 0.0254 m diameter perforated polyvinyl chloride (PVC) pipe in the middle portion of the barrel. The volume of composting waste before modification of the composting barrel was 40% of the original volume and it was 70%, 4 weeks following the modifications. In addition, the nutrients in the compost were found to be in a more suitable range after modification of the composting barrel. The carbon–nitrogen ratio (C/N) of the compost was in the ideal range of 11–15 in the modified composting reactor but it was quite high (24–25) in the conventional barrel. This modified barrel composting plant proved to be an efficient, eco-friendly, cost-effective solution for the management of organic solid waste materials in developing and technologically less sophisticated countries such as Bangladesh. </jats:p
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
