Supercritical CO 2 extraction of soybean oil was performed. Response surface methodology was applied to evaluate the effects of pressure, temperature and extraction time on soybean oil yield. The analysis of variance showed that pressure and extraction time followed by the quadratic term of pressure and interaction between pressure and time had the significant effect on the oil yield. The maximum extraction yield (6.59 ⁄ 100 g soybeans) at constant CO 2 flow rate of 1.629 L per min was achieved at 50°C, 300 bar and 4 h. The experimental values agreed well with those predicted by regression model. One-stage diffusion model was successfully applied for modelling the kinetics of soybean oil. The main triacylglycerols of soybean oil were trilinolein, dilinoleoolein, dilinoleopalmitin and linoleooleopalmitin. Soybean oil extracted by supercritical CO 2 had higher levels of linoleic and linolenic acids and lower levels of palmitic and stearic acids compared to oil extracted by organic solvent.
Slavic folklore contains a variety of beliefs concerning magical animals and other imaginary and liminal beings, their characteristics and properties. This heritage was adopted and used in the past by various children’s authors who integrated these folklore motifs into their own work. Some recent authors, on the other hand, show a marked tendency to implement animals of their own invention in order to convey an ecological message, often employing a quasi-encyclopaedic approach (e. g. Uroš Petrović and Zoran Penevski). Others create imaginary animals in order to explore moral dilemmas and psychological depths in a form appropriate for children (e. g. Mina Todorović). When folklore heritage makes a reappearance, it sometimes takes on a comical function in a contemporary urban context (e. g. Ivana Nešić). In this paper we provide an overview and an analysis of fantastic animals and their heterogeneous origins and functions in contemporary Serbian fantasy written for children, presenting a condensed outline of the most recent developments. Our aim is to combine a traditional analysis of the literary fantastic and folklore elements with ecocriticism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
