Impact of Ozone Dose on Bromate Formation in Water with High Bromide Content and Health Effect
Full text linkFormation of bromate is of a great concern whenever ozonation is used for treating bromide-containing water ever since bromate was classified as a potential carcinogen. This study examines the impact of dose ozone on the bromated formation in groundwater rich in bromide and to estimate the health risks to population due to ingestion. Results of estimated excess cancer risk and chemical toxicity risk to population due to ingestion of treated water were presented and discussed
Hemijske karakteristike analoga sira sa dodatkom biljnih masti i mlečnih proteina
Full text linkThe chemical characteristics of the cheese analogue, which is produced with the addition of vegetable fats and milk proteins, were investigated. The proven fat content in the cheese analogue is 41,39%, which indicates that it is a full-fat product. The average content of total proteins was 6,96% (lower than the usual range for cheese analogues – 11,60% to 14,40%), which can be explained by selecting raw materials and production technology. The mean pH value is slightly lower (4,85) compared to the data of other authors (4,7 to 5,7), and can be attributed to the high content of free fatty acids originating from a mixture of vegetable fats. The NaCl content was 4,19%. The ash content was slightly higher (5,24%) than the results of other authors (4,36%).U radu su ispitivane hemijske karakteristike analoga sira, koji se proizvodi sa dodatkom biljnih masti i mlečnih proteina. Dokazani sadržaj masti u analogu sira je 41,39%, što ukazuje da je to punomasni proizvod. Prosečan sadržaj ukupnih proteina je bio 6,96% (niže od uobičajenog opsega za analoge sireva - 11,60% do 14,40%), što se može objasniti odabirom sirovine i tehnologijom proizvodnje. Srednja vrednost pH je nešto niža (4,85) u odnosu na podatke drugih autora (4,7 do 5,7), i može se pripisati visokom sadržaju slobodnih masnih kiselina poreklom od mešavine biljnih masti. Sadržaj NaCl je bio 4,19%. Sadržaj pepela je bio nešto viši u (5,24%) u odnosu na rezultate drugih autora (4,36%)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
A New Source of Natural Antioxidants From Turkey: Linaria GenistifoliaSubsp. Genistifolia
Full text linkThe antioxidant properties of different solvent extracts (acetone, methanol and water) from Linaria genistifolia subsp. genistifolia were investigated. Antioxidant properties were evaluated by different methods including free radical scavenging (DPPH and ABTS), reducing power (CUPRAC and FRAP), phosphomolybdenum, β-carotene/linoleic acid and metal chelating assays. Also, total phenolic and flavonoid content were determined for each extracts. Generally, the acetone and methanol extracts exhibited strong antioxidant abilities with higher level of phenolics (40.17 mgGAEs/g for acetone and 28.18 mgGAEs/g for methanol). All extracts had remarkable inhibition abilities of linoleic acid oxidation (84.88% for acetone, 77.22% for methanol and 63.04 for water). The results indicate that Linaria genistifolia subsp. genistifolia could be considered as a source of natural antioxidant for preparing new food ingredients and pharmaceutical formulations
