Aesthetics of protest: An examination of the photojournalistic approach to protest imagery

Images of protests and demonstrations are crucial to both social movements and protesters who wish to communicate their identity and their messages to wider audiences. However, the photographing of such political events by press photographers is a complex process. The current analysis focuses on questions of aesthetics surrounding issues of visuality regarding protests and demonstrations. Based on empirical data from 17 semi-structured in-depth interviews with Greek photojournalists, this paper examines what is photographed during a protest and how this is affected by the photojournalists’ aesthetic criteria. Drawing on scholarly work on photojournalism (Ritchin and Åker) and photography (Sontag), this article discusses that besides the presumption in the principal of recording reality, photojournalists’ practice is also infused with subjective language and influenced by art photographers’ techniques. Thereupon, the main argument of this paper is that the employment of hybridized photographing practices by photojournalists can have an impact upon their visual decisions with regard to what and how is photographed during a protest. The product of such practices is usually high quality, captivating images with apparent affective qualities

Mitochondrial nucleoproteins in rye leaves

Some properties of mitochondrial nucleoproteins sedimentable at 100 000 g, corresponding to the hyaloplasmic ribosomes, were compared with those found for two other subfractions isolated from mitochondria of primary rye (Secale cereale) leaves, the pellet sedimentable at 20 000 g and the supernatant remaining alter 100000 g

Rye nuclease I as a tool for structural studies of tRNAs with large variable arms.

A single-strand-specific nuclease from rye germ (Rn nuclease I) was used for secondary and tertiary structure investigations of tRNAs with large variable arms (class II tRNAs). We have studied the structure in solution of two recently sequenced tRNA(Leu): yeast tRNA(Leu)(ncm5UmAA) and bovine tRNA(Leu)(XmAA) as well as yeast tRNA(Leu)(UAG), tRNA(Leu)(m5CAA) and tRNA(Ser)(IGA). The latter is the only tRNA with a long variable arm for which the secondary and tertiary structure has already been studied by use of chemical probes and computer modelling. The data obtained in this work showed that the general model of class II tRNAs proposed by others for tRNA(Ser) can be extended to tRNAs(Leu) as well. However interesting differences in the structure of tRNAs(Leu) versus tRNA(Ser)(IGA) were also noticed. The main difference was observed in the accessibility of the variable loops to nucleolytic attack of Rn nuclease I: variable loops of all studied tRNA(Leu) species were cut by Rn nuclease I, while that of yeast tRNA(Ser)(IGA) was not. This could be due to differences in stability of the variable arms and the lengths of their loops which are 3 and 4 nucleotides in tRNA(Ser)(IGA) and tRNAs(Leu) respectively
