Perspektive razvoja sirarstva
No full textThe analyses of world industrial cheesemaking, as well as, the relation between industrial and farmhouse cheese production procedures are presented in this paper. Strategic guide-lines of cheesemaking development, such as efficiency and consistency of production, maximum yield, overall processing standardization, and also defining special requests pertained to cheese functionality: rheological properties of cheese, melted cheese and cheese flavors are discussed. Health security and nutritive factors of processing and consumption were analyzed. Cheeses, as a friendly environment for bacteria with a probiotic activity, extend certain advantages compared to fermented milk products, due to a higher cheese pH than a corresponding pH value of fermented milk products. Higher pH values provide remarkably longer survival of bacteria, so that even after eight months of cheese ripening, the count of viable cells yields 3x108 0F probiotic strains.U radu je prikazana analiza industrijskog razvoja sirarstva u svetu i veza između zanatskog i industrijskog načina rada. Razmatrani su strateški pravci razvoja sirarstva, kao što su efikasnost i konzistentnost proizvodnje, postizanje maksimalnog randmana, sveobuhvatna standardizacija proizvodnje, kao i definisanje posebnih zahteva u pogledu funkcionalnosti sireva: reoloških karakteristika sirnog testa, rastopljenog sirnog testa i ukusa sireva. Analiziran je zdravstveno bezbednosni i nutritivni faktor proizvodnje i potrošnje sireva. Sirevi, kao sredina za razvoj bakterija sa probiotskim dejstvom, pružaju izvesne prednosti u odnosu na kiselomlečne proizvode, jer je pH vrednost sireva viša od odgovarajuće pH vrednosti kiselomlečnih proizvoda, što omogućava znatno duže preživljavanje bakterija, tako da se u siru i posle osam meseci zrenja nalazi 3 x 108 živih ćelija bakterija sa probiotskim dejstvom
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
Sirevi sa smanjenim sadržajem masti
Get PDFReduced fat cheeses are usually characterized as having poor texture, flavor and functional characteristics. Procedures developed for manufacturing reduced and low fat cheeses include modification of technological procedures, starter cultures selection and use of additives, as fat substitutes.Sirevi sa smanjenim sadržajem masti se najčešće karakterišu kao sirevi sa manje prihvatljivom teksturom, slabo izraženim i netipičnim ukusom i mirisom i slabim funkcionalnim osobinama. Prevazilaženje navedenih problema u proizvodnji sireva sa smanjenim sadržajem masti se zasniva na modifikaciji tehnološkog postupka proizvodnje, upotrebi odgovarajućih starter kultura i aditiva, kao zamenjivača mlečne masti
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
Sirevi sa dijetetskim i funkcionalnim svojstvima
Get PDFModern medicine indicates the strong importance of diet in the preservation and the improvement of people's health. Hence, during the last few decades, a substantial interest for the production of cheeses with dietetic and functional properties has been present. Current investigations on production of cheeses with reduced fat and salt content, as well as cheeses with probiotic bacteria and dietary fibre are shown. .Savremena kretanja u medicini ukazuju na značaj načina ishrane u očuvanju i poboljšanju zdravlja ljudi. S tim u vezi, poslednjih godina prisutno je izraženo interesovanje za sagledavanje mogućnosti proizvodnje sireva sa dijetetskim i funkcionalnim svojstvima. U radu su prikazana dosadašnja istraživanja o proizvodnji sireva sa smanjenim sadržajem masti i soli, kao i sireva sa probiotskim bakterijama i prehrambenim vlaknima koji pripadaju grupi proizvoda sa izraženim dijetetskim i funkcionalnim svojstvima.
Proizvodnja sireva sa probiotskim bakterijama
No full textVeliki broj različitih vrsta sireva predstavlja podesan sistem prenosa probiotskih sojeva bakterija mlečne kiseline do intestinalnog trakta ljudi. Relativno visok pH, čvrsta konzistencija, viši sadržaj masti i veći puferski kapacitet, bez sumnje, sireve čine podesnim medijumom za razviće i zaštitu ovih sojeva. Za uspešno inkorporiranje sira veoma je važan odabir vrste sira, budućeg nosioca probiotika. Dosadašnja ispitivanja mogućnosti inkorporiranja probiotika u pojedine grupe sireva pokazuju visok stepen njihove vijabilnosti tokom perioda zrenja i skladištenja, što čini osnovne kriterijume probiotske aktivnosti. Savremeni zahtevi potrošača i današnji trendovi na tržištu u velikoj meri ukazuju na popularnost i potrebe proširenja asortimana proizvoda sa izraženim zdravstvenim efektima. U tom smislu industriji mleka se jasno postavljaju specifični zahtevi za novim tehnologijama i proizvodima, koji delom pripadaju i sirevima sa probioticima. Pravilnim izborom vrste sira i tehnološkog postupka proizvodnje, agresivnim marketingom, isticanjem zdravstvenih aspekata proizvoda, potrebnih doza konzumiranja, potrebnih informacija na deklaracijama proizvoda i jakim regulatornim sistemom može se proizvesti velika zainteresovanost potrošača, rast prodaje i uspešnost proizvodnje sireva sa probioticima
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
