Influence of raw material composition on the quality of pelleted forage for ruminants
No full textIstraživanje je provedeno u Tvornici stočne hrane Belje. Cilj istraživanja bio je utvrditi utjecaj komponenti u sastavu smjese na kvalitetu peleta. U istraživanju se kvaliteta peleta krmne smjese određivala s PDI (pellet durability indeks) indeksom koji pokazuje trajnost peleta. Također, promatrani su: utrošak energije peletirke, temperatura peletiranja, temperatura uzorka nakon kondicioniranja, vlaga uzorka nakon kondicioniranja, temperatura uzorka nakon prolaska kroz matricu peletirke i vlaga uzorka nakon prolaska kroz matricu peletirke. Testiranje je provedeno na četiri smjese, za koje je najprije izračunat FPQF (feed pellet quality factor) faktor, te je svaka smjesa zamiješana osam puta. Nakon peletiranja i hlađenja smjese su testirane uređajem za određivanje PDI indeksa. Iz dobivenih rezultata može se zaključiti kako različit sastav krmiva u krmnoj smjesi može utjecati na kvalitetu peleta krmne smjese.The research was carried out at the Belje Animal Feed Factory. The aim of the study was to determine the influence of the components in the composition of the mixture on the quality of the pellets. In the study, the quality of feed pellets was determined using a PDI (pellet durability index) index that indicates the durability of the pellets. Also observed were: pelletizer energy consumption, pelletizing temperature, sample temperature after conditioning, sample temperature after passing through the pelletizer matrix, and sample moisture after passing through the pelletizer matrix. Testing was performed on four mixture, for which the FPQF (feed pellet quality factor) factor was first calculated, and each mixture was mixed eight times. After pelleting and cooling, the mixtures were tested wiht a PDI device. From the obtained results, it can be concluded that different feed composition of the feed mixture may affect the quality of the feed pellet

No full textIstraživanje je provedeno s ciljem utvrđivanja utjecaja strukture krmiva u obroku na proizvodne pokazatelje teladi u fazi nakon odbića. Ženska grla teladi Holstein pasmine podijeljena su u tri skupine prema tretmanu te je u svakoj skupini bilo šest životinja. Tretmani su podijeljeni na sljedeći način: kontrolna skupina (K) hranjena je peletiranom GT-1 smjesom, prva pokusna skupina (P1) hranjena je miješanim obrokom suhog TMR-a i peletirane GT-1 smjese u omjeru 40 : 60 % u korist TMR-a, druga pokusna skupina (P2) hranjena je suhim potpuno izmiješanim obrokom (TMR). Hranidba i napajanje teladi bilo je ad libitum sa svježe pripremljenom hranom i vodom. Istraživanje je trajalo 30 dana. Praćeni su sljedeći proizvodni pokazatelji: dnevni prirast, ukupni prirast, konzumacija hrane, konverzija hrane, tjelesne mjere, indeksi anamorfoznosti i tjelesne kompaktnosti. Od biokemijskih pokazatelja u krvi praćene su vrijednosti glukoze, kreatina, uree, omjera uree i kreatina, ukupnog proteina, albumina, globulina, omjera albumina i globulina, triglicerida, alanin aminotransferaze, aspartat aminotransferaze i alkalne fosfataze. Vaganje, uzimanje tjelesnih mjera te vađenje krvi rađeni su 1. i 30. dana istraživanja. Nisu utvrđene značajne razlike u ukupnom i dnevnom prirastu, tjelesnim mjerama kao i u indeksima anamorfoznosti i tjelesnoj kompaktnosti. Nije bilo ni značajnih razlika u biokemijskim pokazateljima u krvi. Konzumacija i konverzija hrane bila je najviša u prvoj pokusnoj skupini. Na temelju rezultata ovog istraživanja može se zaključiti kako se kombinacija starter smjese za telad GT-1 i suhog TMR-a pokazala najboljim izborom u vezi s konzumacijom hrane.The research was conducted with the aim of determining the influence of the feed structure in the meal on the production indicators of calves in the post-weaning phase. The female calves of the Holstein breed were divided into 3 groups according to the treatment, and there were 6 animals in each group. The treatments were divided as follows: the control group (K) was fed a pelleted GT-1 mixture, the first experimental group (P1) was fed a mixed meal of dry TMR and pelleted GT-1 mixture in a ratio of 40 : 60 % in favor of TMR, the second experimental group (P2) was fed with dry total mixed ratio (TMR). Calves were fed ad libitum with freshly prepared feed and water. The research lasted 30 days. The following production indicators were monitored: daily gain, total gain, feed consumption, feed conversion, body measurements, anamorphism and body compactness indices. Among the biochemical indicators in the blood, the values of glucose, creatine, urea, ratio of urea to creatine, total protein, albumin, globulin, ratio of albumin to globulin, triglycerides, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase were monitored. Weighing, taking body measurements and blood sampling were done on the 1st and 30th day of the research. No significant differences were found in total and daily growth, body measurements, as well as in anamorphosis and body compactness indices. There were no significant differences in the biochemical indicators in the blood. Feed consumption and conversion was the highest in the P1 experimental group. Based on the results of this research, we can conclude that the combination of starter for calves GT-1 and dry TMR proved to be the best choice in terms of food consumption
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
