Strategic Priorities in Development of the Agro-Industrial Complex of the Krasnodar Region

The paper gives the agro-industrial complex characteristic of the Krasnodar Krai, analyzes the condition of its branches and defines key problems. It emphasizes such strategic development priorities of the agro-industrial complex of the Krasnodar Krai as the reclamation of land, development of the elite seed industry, intensive development of the animal industry, support of the small forms of economic management. The paper also considers the possibilities of the state support for regional agroproducers taking into account the entry of the Russian Federation in the ranks of the World Trade Organization. In compliance with that the paper offers the measures of the state regulation that is aimed to stimulation of key directions of the agrarian industry development of the region where the matter concerns a creation of the logistic basis and formation of the rural cooperation. As an example a model of the contract relations system concerning production, processing and sales of the pig-breeding products between the agricultural organizations, farm enterprises and farms of the population which can be used during the organization of productive processes both in other subsectors of the animal industry and in the branch of the plant industry. There is a conclusion that now a concentration of the state regulation on the oblique support measures for strategic development directions that is capable to provide a stimulation of "independent mechanisms" of the inner potential of the agro-industrial complex of the Krasnodar Krai.

B Production Asymmetries in Perturbative QCD

This paper explores a new mechanism for B production in which a b quark combines with a light parton from the hard-scattering process before hadronizing into the B hadron. This recombination mechanism can be calculated within perturbative QCD up to a few nonperturbative constants. Though suppressed at large transverse momentum by a factor Lambda_QCD m_b/p_t^2 relative to b quark fragmentation production, it can be important at large rapidities. A signature for this heavy-quark recombination mechanism in proton-antiproton colliders is the presence of rapidity asymmetries in B cross sections. Given reasonable assumptions about the size of nonperturbative parameters entering the calculation, we find that the asymmetries are only significant for rapidities larger than those currently probed by collider experiments.Comment: 17 pages, LaTeX, 4 ps figures, tightenlines, sections added, final version accepted for publication in Phys.

Mass spectra of doubly heavy Omega_QQ' baryons

We evaluate the masses of baryons composed of two heavy quarks and a strange quark with account for spin-dependent splittings in the framework of potential model with the KKO potential motivated by QCD with a three-loop beta-function for the effective charge consistent with both the perturbative limit at short distances and linear confinement term at long distances between the quarks. The factorization of dynamics is supposed and explored in the nonrelativistic Schroedinger equation for the motion in the system of two heavy quarks constituting the doubly heavy diquark and the strange quark interaction with the diquark. The limits of approach, its justification and uncertainties are discussed. Excited quasistable states are classified by the quantum numbers of heavy diquark composed by the heavy quarks of the same flavor.Comment: 14 pages, revtex4-file, 3 eps-figures, 5 tables, typos correcte

On the mechanisms of heavy-quarkonium hadroproduction

We discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia in the light of computations of higher-order QCD corrections both in the Colour-Singlet (CS) and Colour-Octet (CO) channels and the inclusion of the contribution arising from the s-channel cut in the CS channel. We also discuss new observables meant to better discriminate between these different mechanisms.Comment: Invited review talk at 3rd International Conference On Hard And Electromagnetic Probes Of High-Energy Nuclear Collisions (HP2008), 8-14 June 2008, Illa da Toxa, Galicia, Spain. 11 pages, 21 figures, LaTeX, uses svjour.cls and svepj.clo (included

Heavy quarkonium: progress, puzzles, and opportunities

A golden age for heavy quarkonium physics dawned a decade ago, initiated by the confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of related experimental activity. The early years of this period were chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in 2004, which presented a comprehensive review of the status of the field at that time and provided specific recommendations for further progress. However, the broad spectrum of subsequent breakthroughs, surprises, and continuing puzzles could only be partially anticipated. Since the release of the YR, the BESII program concluded only to give birth to BESIII; the $B$-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA and the Tevatron matured; and heavy-ion collisions at RHIC have opened a window on the deconfinement regime. All these experiments leave legacies of quality, precision, and unsolved mysteries for quarkonium physics, and therefore beg for continuing investigations. The plethora of newly-found quarkonium-like states unleashed a flood of theoretical investigations into new forms of matter such as quark-gluon hybrids, mesonic molecules, and tetraquarks. Measurements of the spectroscopy, decays, production, and in-medium behavior of c\bar{c}, b\bar{b}, and b\bar{c} bound states have been shown to validate some theoretical approaches to QCD and highlight lack of quantitative success for others. The intriguing details of quarkonium suppression in heavy-ion collisions that have emerged from RHIC have elevated the importance of separating hot- and cold-nuclear-matter effects in quark-gluon plasma studies. This review systematically addresses all these matters and concludes by prioritizing directions for ongoing and future efforts.Comment: 182 pages, 112 figures. Editors: N. Brambilla, S. Eidelman, B.

FEM-based calculation of soil mass with the impact of dilatancy

There are a lot of papers about dilatancy, it is typical for the majority of highly concentrated dispersed systems. A three-dimensional deformation in the active zone of such systems is contraction and deformation by dilatancy. An increase is called dilatancy, a decrease is called negative dilatancy or contraction. The violation of soil strength due to a shift in one of the ground on the other is the most common fracture in the construction of excavation slopes. In this paper, we use a model similar to the model of a perfectly plastic body. The construction of a computational algorithm is based on sampling the computational domain in the finite element method. The modeling of soil is based on specific strength properties which determine its bearing capacity. They include the cohesion coefficient, the angle of internal friction coefficient and dilatancy coefficient, which characterizes soil loosening or compaction under deviatoric loads. The paper considered a number of model problems of elastic-plastic deformation of a dirt mound, studied the convergence of the solutions. It may be noted that the inclusion of the dilatancy decelerates the mound transition to the limiting state, and thereby a second band slip is forming. The implemented methodology allows the calculation of elastic-plastic deformation of soil masses, complying with the law of dry friction with and without dilatancy

The precursor of differentiation factor HLDF and ribosomal protein RPS21 have a common N-terminal sequence

The mature differentiation factor HLDF, isolated from cultural medium, comprises 54 aa, whereas the open reading frame of mRNA encodes a 97-aa protein. We presumed that the protein translation begins from the first ATG codon, whose environment mostly meets the requirements for the initiation point. Two more ATG triplets are localized in positions 48-50 and 100-102 (numbering according to the structure of S21), i.e., in the area preceding the cDNA fragment that encodes the N-terminal fragment of the mature protein. The mRNAs of HLDF and S21 ribosomal protein have previously been shown to be highly homologous, and, therefore, their differences appear to be derived from two point deletions in the cDNA of the HLDF-encoding sequence (a G residue in position 112 and a C residue in position 224). As a result, the mature differentiation factor and RPS21 may be the products of translation from different open reading frames, the differentiation factor may be synthesized in the cell as a precursor, and its N-terminal sequence may be identical to that of RPS21. To test this hypothesis, we prepared recombinant RPS21 and the polyclonal antibodies to HLDF, full-size RPS21, and the C-terminal RPS21 peptide. Immunochemical staining by specially produced antibodies of native HL-60 cells and the same cells brought into apoptosis or differentiation confirmed that the precursor of the differentiation factor and the ribosomal S21 protein have a common N-terminal sequence and different cellular localizations. Neither an intron-containing gene nor a pseudogene with the nucleotide sequence corresponding to the HLDF cDNA was detected in the human genome or in the HL-60 cell line genome. On the basis of these facts, we propose a hypothesis of the molecular mechanism of the HLDF mRNA biosynthesis by means of posttranslational modifications of pre-mRNA of RPS21
