In this paper, we discuss the DNA construction of general length over the finite ring [Formula: see text], with [Formula: see text], which plays a very significant role in DNA computing. We discuss the GC weight of DNA codes over [Formula: see text]. Several examples of reversible cyclic codes over [Formula: see text] are provided, whose [Formula: see text]-images are [Formula: see text]-linear codes with good parameters.

Ever since the first appearance of deoxyribose nucleic acid (DNA) in 1953, it has fascinated multitudes with its simplicity. With a modest syllabus of four nucleotides (adenine, thymine, cytosine and guanine), it codes for the complexity of life around us. In this paper, we investigate how the structure of DNA codes for life processes and how we can take advantage of its minuscule size, mechanism of self-recognition and self-assembly for "bottom-up" nanotechnology. High hopes are also placed on miniaturizing present computing technology using DNA computing based on two fundamental features; massive parallelism of DNA strands and Watson–Crick complementarity. Advances in DNA-based computation and algorithmic assembly are then used to complement researches in DNA nanotechnology.

The article studies different shell constructions of mid-water trawls and their properties. The problem settled is suggested to be solved taking into account real geometric interrelations between spacious and surface properties of cone shells. The author suggests to accept a so-called geometric quality coefficient as a criterion of the properties of a conical shell, which represents the ratio of the shell to the area of its side surface and by analogy to use it to the shell of the trawl. The relationship between the trawl dimensions and geometric quality coefficient have been studied. Comparing these figures with the actual characteristics of trawls showed good convergence. According to the results of theoretic analysis and parameters calculation, trawl large-size shells will always have advantages in geometric characteristics over mid-size and, especially, small-size shells. The results of the analysis can be used for approximate calculations of the parameters of the trawl and justification of ways to improve the performance of existing mid-water trawls.
