In the current work, the productivity of single and twofold collar in decreasing scour rate and profundity around round and hollow extension wharfs was concentrated tentatively. To diminish the strength of wake vortices, various quantities of bars were likewise introduced at the downstream essence of the wharf in mix with a solitary collar. The best outcome was accomplished for twofold collar when the collars were introduced at the streambed level and one wharf measurement beneath bed level. With this game plan the lower collar was not sabotaged following 80 hours of trial, appearing around 56 % decrease in scouring contrasted and an unprotected dock. It was likewise shown that by utilizing collars, the pace of scouring diminished impressively. However establishment of bars didn't fundamentally diminish the greatest profundity of scour, it delayed the start of scouring at the upstream essence of the wharf.

Creativity and inspiration, poetry and poetry, interpretation and image, plot and fable all come together at a single point - composition. The poet uses words, repeats, intensifies the image and tone, assigns a meaningful meaning to them, arranges them, organizes them, and all this unites in a single aesthetic center. So, can a composition be a masterpiece? What about modern poetry? No, each work has its own compositional quality and limit of philosophical scope. Just as there is a certain order in every phenomenon in the universe, there is also a certain compositional principle in modern poetry.

The article presents an analysis of the test results obtained by pulling out a reinforcing bar from a concrete sample. In experiments, the reinforcement diameter and concrete strength were taken as variable factors. The results were used to analyze the indicators of coupling of the reinforcement with concrete, the tension-strain state and the nature of fracture of the test specimens to establish the patterns of their changes. The summarized data are presented in tabular form.
