The article is devoted to the study of the relationship of non-Euclidean symmetries in inherited biostructures with algebraic features of information nucleotide sequences in DNA molecules in the genomes of eukaryotes and prokaryotes. These genomic sequences obey the universal hyperbolic rules of the oligomer cooperative organization, which are associated with the harmonic progression 1/1, 1/2, 1/3,.., 1/n. The progression has long been known and studied in various branches of mathematics and physics. Now it has manifested itself in genetic informatics. The performed analysis of the harmonic progression revealed its connection with the cross-ratio, which is the main invariant of projective geometry. This connection consists in the fact that the magnitude of the cross-ratio is the same and is equal to 4/3 for any four adjacent members of this progression. The long DNA nucleotide sequences have fractal-like structure with so called epi-chains, whose structures are also related to the harmonic progression and the projective-geometrical symmetries. The received results are related additionally to a consideration of DNA double helix as helical antenna. This fact of the connection of genetic informatics with the main invariant of projective geometry can be used to explain the implementation of some non-Euclidean symmetries in genetically inherited structures of living bodies.

The fine structure of the Z-disk in rat striated muscle has been found to be dependent upon the manner of its fixation. Material primarily fixed in osmium tetroxide shows a square or ‘woven’ lattice in transverse sections, with a spacing of around 22 nm, and with its axes off-set by 45° from the axes of alignment of the files of I-filaments prior to their entry into the Z-disk. In longitudinal sections the disk may have a zig-zag appearance with individual I-filaments of one sarcomere apparently linked obliquely to 2 or more I-filaments of the next. Transverse sections of Z-disks in muscle primarily fixed in glutaraldehyde show a square-lattice pattern with a spacing of about II nm, its axes coinciding with the axes of alignment of the adjacent I-filaments. In longitudinal sections oblique linkages of the ends of the I-filaments are not seen, and they appear either to interdigitate, or to be longitudinally continuous with those of the next sarcomere. This second fine structure is interpreted as being the consequence of the superimposition of 2 basic square lattices, each of 22-nm period, 50 % out of register along each axis, and each fort-ned from the lateral linkage of the ends of the interdigitating I-filaments with the ends of adjacent filaments from their own sarcomere. The relationship of this postulated structure to the lattice patterns previously described, the nature of the cross-linking material, and some possible functional implications are briefly discussed.

AbstractThe controversial gambling decision of the Appellate Body is mostly important because of examination of the nature of Access under Article XVI GATS, the relationship of that Article to Articles XIV and XVII GATS, and the parallels with Articles III, XI, and XX GATT. Notably, the Appellate Body took the position that an apparant internal regulatory measure, which, nonetheless, had equivalent effect to a zero quota, violated Article XVI GATS. A similar measure in the area of goods would have been examined under Article III GATT and require a showing of discrimination. The facts of the case would have allowed the decision to be based on Article XVII GATS. Most of this paper deals with this issue. We agree with this interpretation of Article XVI by the Appellate Body but are critical of its hermeneutics, suffering from a textual fetish and a policy phobia. Some other elements in the decision are also examined critically.

Chapter Three opens Part Two of this work, which looks at what it is that is ‘finished’, as Christ affirms with his last word from the Cross in the Gospel of John. This chapter focuses on Christ as the true Temple, erected when his body is lifted up upon the Cross, Building upon the work of Mary Coloe and others, this chapter explores how Christ is presented in the six feasts which structure the narrative of this Gospel, culminating in the Passion and the appearances of the Risen Christ on the first and eighth day. In addition, this chapter also examines the way in which imagery drawn from the Tabernacle and Temple are used to explain Christ’s flesh (John 1:14 and 6), the relationship of this flesh, his glorified body, to the Eucharist and martyrdom, broadening in this way what is meant by ‘incarnation’.

The sperm flagella of the blowfly Sarcophaga bullata demonstrate the relationship of radial projections in the matrix region to the microtubule organization of the axoneme. The A microtubule of each peripheral doublet is connected to the central sheath by a series of paired radial links. The links lie along the tubule wall with a alternate spacing of about 320/560 A. The distal end of each link is enlarged into a globular head that connects via a transitional link to the helical sheath around the central microtubules. The radial link pairs are disposed in the form of a double helix with a pitch of about 1760 A. It is proposed that a similar organization is common to all cilia and flagella showing ninefold symmetry and must provide, in part, the morphological basis for motility.

This paper documents the detailed investigation of the relationship between molecular structure and biological activity of few tetraaza macrocyclic metal (II) complexes equipped by the template condensation of o-bromoaniline, ethylenediamine and salbenz in 2:1:1 ratio with metal (II) salts (1mM). All these complexes are found to be stable in air and soluble in CN3CN or DMSO, and are characterized through spectral (UV-Vis, IR, EPR) and electrochemical methods. A square planar geometry is proposed for Cu(II), Ni(II) and Co(II) complexes, while an octahedral geometry is suggested for Mn(II) and Fe(II). The IR spectra indicate that the NH groups of the amine exist as such even after complexation without deprotonation, and all the complexes show a strong band in 1580-1590 cm-1region corresponding to ν(C=N), due to coordinated azomethine group to the metal. The solution electronic spectra of these complexes show intense LMCT bands around 400 nm. Intense electronic absorption spectra as well as the four line pattern in EPR spectra with broad g⊥suggests that the copper(II) complexes have distorted square planar geometry. On titration with herring sperm DNA, CuN4,CoN4,NiN4and MnN4complexes exhibit an abrupt amend in their electronic spectrum and cyclic voltammogram. The intense intraligand π-π* transition in the region 350–420 nm is found to show hypochromicity on titration with DNA in all these complexes, due to their electrostatic interaction with DNA. All these complexes show one well–defined quasi-reversible redox couple with values ranging from ∆Ep 137 to 337 mV. Their spectral and electrochemical outcome designate that the square planar complexes Cu(II), Co(II) and Ni(II) interact much better than the axially coordinated octahedral complexes Mn(II) and Fe(II). The decrease found in the negative absorption peak, characteristic peak due to helicity of DNA, in circular dichroism studies reflects the perversion in the helical nature of B-DNA upon the addition of complex. The binding of plasmid DNA by these complexes has also been investigated by agarose gel electrophoresis, remarkably Ni(II) complex was found to cleave the DNA double helix.

Paspalum conspersum Schrad. ex Schult., 2n = 4x = 40, was crossed with P. intermedium Munro ex Morong, 2n = 2x = 20, and P. jurgensii Hackel, 2n = 2x = 20, and the hybrids were studied cytologically to determine the relationship between these species. Thirteen P. intermedium × P. conspersum hybrid plants were produced; however, only eight survived. They had a chromosome number of 2n = 3x = 30. Meiosis was irregular with a chromosome pairing relationship of 19.87 univalents, 5.03 bivalents, and 0.03 trivalents per cell. These findings suggested that the two species have a partially homologous genome. The two hybrids obtained from the cross between P. jurgensii and P. conspersum had a chromosome number of 2n = 3x = 30. The mean chromosome pairing in these hybrids was 10.12 univalents. 9.86 bivalents, 0.08 trivalents, and 0.004 quadrivalents. The close bivalent pairing and a mean frequency of 9.86 bivalents suggested that the P. jurgensii genome was homologous to one genome of P. conspersum. Limited autosyndetic pairing of the P. conspersum chromosomes was also detected in both groups of hybrids. A standardization of genome formulas for the genus was proposed in which P. intermedium, P. jurgensii, and P. conspersum were represented by genome formulas of II, JJ, and I2I2 JJ, respectively. The genome relationships and formulas were discussed for other related Paspalum species.

For an active multi-port network of a direct current, as a model of a power supply system, the problem of recalculation of the changeable loads currents is considered. The approach on the basis of projective geometry is used for interpretation of changes or "kinematics" of regime parameters of a circuit. The changes of the regime parameters are introduced otherwise, through the cross ratio of four points with use of projective coordinates. Easy-to-use formulas of the recalculation of the currents, which possess the group properties at change of conductivity of the loads, are obtained. It allows expressing the final values of the currents through the intermediate changes of the currents and conductivities. Disadvantages of the traditional approach, which uses the changes of resistance in the form of increments, are shown. The given approach is applicable to the analysis of "flowed" form processes of the various physical natures.

Cooperativa. Organizational structure and governance: a case study in a cooperative institutionAbstract: This research presents a conceptual analysis of organizational structure and a synthesis of the cooperative system. It takes into consideration organizational themes in order to show the modern structures reporting on the practices of governance, which, at the same time, have gained prominence in the corporate universe when it comes to managing organizations and reducing risks. This study aims to verify how the concepts of organizational structure and governance can be developed in a cooperative organization and what influences these definitions bring to the organization's environment. Methodologically, it is generated as a case study, descriptive with a qualitative approach, being structured in conceptual, contextual and based aspects in the data collection, which occurred through in loco research. The collected data show that the cooperative studied should institute, in an objective and consensual way, training programs with the training program of leaders and advisers in the area of training in cooperative governance and cooperative management. It is concluded that the challenge of a change in the organizational structure, and in the culture itself, is part of the cooperative and managers who must seek the development or expansion of processes and practices regarding decision making, optimizing the communication and the relationship of those involved, improving management knowledge, and maximizing the transparency of managers and the business itself.Keywords: Organizational structure.

The article deals with questions of the relationship of theories of history and theologies of liberation. More specifically, the guiding question is what theory of history does a theology of liberation require. To answer this, Marx and Lonergan are brought into dialogue with Latin American liberation theologians to compare and test the cogency of these two thinkers with Latin American thought.
