No full textAntioxidant potential of bee pollen
No full textNamen magistrske naloge je bil določiti vsebnost skupnih fenolnih spojin, skupnih flavonoidov ter posameznih skupin flavonoidov in ugotoviti antioksidativni potencial (AOP) cvetnega prahu osmukanca. Zanimal nas je vpliv shranjevanja in sušenja cvetnega prahu na preiskovane lastnosti. Izvlečke fenolnih spojin smo pripravili s solventno ekstrakcijo z uporabo 96 % oz. 60 % etanola. AOP smo določili z metodo lovljenja prostega radikala DPPH∙ in z metodo beljenja β-karotena, ki temelji na sposobnosti zaviranja lipidne oksidacije v emulziji. V svežem cvetnem prahu osmukancu, kjer smo izvedli ekstrakcijo s 96 % etanolom, smo določili vsebnost skupnih fenolnih spojin 6-13 mg galne kisline/g suhe snovi in vsebnost flavonoidov 5-13 mg rutina/g suhe snovi. Izvlečki, ki smo jih pridobili s 96 % etanolom, so vsebovali manj skupnih fenolnih spojin in več skupnih flavonoidov od izvlečkov, pridobljenih s 60 % etanolom. Med skladiščenjem svežega cvetnega prahu osmukanca v hladilniku, se vsebnost skupnih fenolnih spojin ne spremeni, zmanjša se vsebnost skupnih flavonoidov. Med sušenjem se zmanjša vsebnost skupnih fenolnih spojin, predvsem flavonoidov. Eden od vzorcev je pokazal AOP, primerljiv z AOP galne kisline, ostali vzorci so bili slabši lovilci DPPH∙. V emulziji izvlečki cvetnega prahu osmukanca, ki smo jih pripravili s 96 % etanolom, kažejo večjo učinkovitost od izvlečkov, pripravljenih s 60 % etanolom. Izvlečki so v emulziji pokazali učinkovitost, primerljivo s sintetičnim antioksidantom butiliranim hidroksitoluenom.The purpose of this graduation thesis was to determine total phenolic content, total flavonoid content and individual groups of flavonoids, and to determine the antioxidative potential (AOP) of bee pollen. The extracts of phenolic compounds were prepared by the solvent extraction with 96 % and 60 % ethanol. AOP was determined with the DPPH∙ radical scavenging method and the method of bleaching β-carotene which is based on the ability to inhibit lipid oxidation in the emulsion. In fresh bee pollen where extraction with 96 % ethanol was used we determined the total phenolic content of 6-13 mg gallic acid/g of dry matter and total flavonoid content of 5-13 of rutin/g of dry matter. The extracts obtained with 96 % ethanol, contained less total phenolic compounds and more total flavonoids than the extracts obtained with 60 % ethanol. During storage of bee pollen in the refrigerator, the content of phenolic compounds remained unchanged, the content of total flavonoids decreased. During drying the content of phenolic compounds decreased, especially flavonoids. One of the samples showed AOP, which was comparable to AOP of gallic acid, other samples showed lower DPPH∙ scavenging activity. Extracts prepared with 96 % ethanol were more efficient in emulsion than those prepared with 60 % ethanol. In emulsion the extracts showed efficacy comparable to the synthetic antioxidant butylated hydroxytoluene

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
