Introduction. The article is devoted to the typological and chronological analysis of the details of three prestigious belt sets stored in the funds of the G.N. Prozritelev and G.K. Prave Stavropol State History, Culture and Natural Landscape Reserve Museum. Methods and materials. The comparative typological method is used as a working one. It is based on the classification by material, processing method, shape, ornament, as well as on the selection and study of the types of buckles and waist plaques. The comparative analysis of the decor of belt parts from the Stavropol Museum and the like found in the Don region, Prikamye and on the territory of Hungary allows us to characterize the technology for producing a belt headset in the region in the 8th – 9th centuries. Analysis. The composition of the belt headset of the first belt found in a rich burial in Sadovoye, Arzgirsky District, Stavropol Krai, includes an iron buckle with an oval-triangular frame and a rectangular shield with a zavovanny edge, a belt tip, a clip, and a buckle. Every item is inlaid with thin gold plates. On the flap buckle and clip they are laid out in the form of a spiral. On every detail of the girdle, the gold foil is decorated with floral ornaments: five-beam rosettes, heraldic lilies (they even adorn the buckle frame), shoots with buds and leaves. Belt no. 2 found in 1969 in the rich burial 2 of Eshkakon burial ground no. 3, most likely, consisted of a belt and harness belts. The girdle set includes 10 heart-shaped patches (plaques), 4 elongated pads with rectangular slots, 9 round-triangular plaques with suspended movable rings (three rings are missing) and an oval-triangular buckle (rectangular shield is lost). Every listed item is made of white metal (silver). A floral ornament consisting of shamrocks (lotuses) is applied on the front side of all the buckles. Belt no. 3, which is also found in one of the Eshkakon burial grounds, consists of a buckle with a triangular frame and a pentagonal shield and 10 plaques of rounded triangular shape with suspended movable rings. Every item is made of bronze. Results. The rich funerary inventory of the burials in which the belts were found and their comparison with complexes that include a similar belt headset from other regions, indicate that all three belts from the Stavropol State Museum-Reserve are attributes of the military aristocracy of the second half of the 8th – 9th centuries. Chronologically, belt no. 1 is the earliest. Belt no. 2 should be considered close in time. The latest is belt no. 3.

The article is an abbreviated and multimedia variation of the A.Chernyshov dissertation’s chapter for the degree of Doctor of Arts, which was written in 2012 (p. 222-240). This chapter explores the types of leitmotif technology in a multi-part fiction film. For the first time in the history of art criticism, the author examines the musical-compositional form-construction of a series, highlighting "external" leitmotivs (leitmotif-callsign, leitmotif-while-credits) and "internal" leitmotivs. The author compares the variant development of music themes of the "traditional leitmotiv technique" to the invariant "clip technique". In the modern television series, the author finds mixed types of musical-leitmotiv techniques, predicting the further development of this media genre.

RNA-binding proteins (RBPs) play an important role in regulating gene expression at the posttranscriptional level, including the steps of pre-mRNA splicing, polyadenylation, mRNA stabilization, mRNA export from the nucleus to the cytoplasm, mRNA localization, and translation. RBPs regulate these processes primarily by binding to specific sequence elements in newly synthesized or mature transcripts. While many RPBs are known to recognize certain nucleotide sequences in RNA, information is insufficient for others. In particular, RBPs often compete for RNA binding or interact with RNA cooperatively. Hence, it is of importance to study the RNA-protein interactions in vivo. Numerous methods have been developed to identify the target nucleotide sequences of RBPs. The methods include the electrophoretic mobility shift assay (EMSA), systematic evolution of ligands by exponential enrichment (SELEX), RNA pull-down assay, RNA footprinting, RNA immunoprecipitation (RIP), UV-induced crosslinking immunoprecipitation (CLIP) and its variants, and measurement of the level for newly synthesized transcripts. Each of the methods has its limitation, and several methods supplementing each other should be employed in order to detect the RNA sequence to which a protein binds.
