This paper deals with the study of the relationship between parameters of the Peyer’s patches of the small intestine in intact rats of different age groups. The correlation analysis revealed the direct relationship between the parameter

Symmetry adapted ro-vibrational basis functions for variational nuclear motion calculations: TROVE approach

We present a general, numerically motivated approach to the construction of symmetry adapted basis functions for solving ro-vibrational Schr\"{o}dinger equations. The approach is based on the property of the Hamiltonian operator to commute with the complete set of symmetry operators and hence to reflect the symmetry of the system. The symmetry adapted ro-vibrational basis set is constructed numerically by solving a set of reduced vibrational eigenvalue problems. In order to assign the irreducible representations associated with these eigenfunctions, their symmetry properties are probed on a grid of molecular geometries with the corresponding symmetry operations. The transformation matrices are re-constructed by solving over-determined systems of linear equations related to the transformation properties of the corresponding wavefunctions on the grid. Our method is implemented in the variational approach TROVE and has been successfully applied to a number of problems covering the most important molecular symmetry groups. Several examples are used to illustrate the procedure, which can be easily applied to different types of coordinates, basis sets, and molecular systems

NMR and LDA evidence for spiral magnetic order in the chain cuprate LiCu2O2

We report on {6,7}Li nuclear magnetic resonance measurements of the spin-chain compound LiCu2O2 in the paramagnetic and magnetically ordered states. Below T about 24 K the NMR lineshape presents a clear signature of incommensurate (IC) static modulation of the local magnetic field consistent with an IC spiral modulation of the magnetic moments. {7}Li NMR reveals strong phason-like dynamical fluctuations extending well below 24 K. We hypothesize that a series of phase transitions at 24.2, 22.5, and 9 K reflects a "Devil's staircase" type behavior generic for IC systems. LDA based calculations of exchange integrals reveal a large in-chain frustration leading to a magnetical spiral.Comment: 4 pages, 4 figure

Microscopic features of buccal epithelium in smokers students indo-dravidian race: by E. Hooton

We have studied the microscopic features of buccal epithelium in smoking students of Indo-Dravidian race. In the epithelial cells of the mucous cheek surface of smoking students we revealed the scored nuclei with tongue- and broken egg-type protrusions, micronuclei, cellular dimorphism, binuclear cells, as well as a significant decrease in nuclear-cytoplasmic ratio, as compared to the control, which may indicate the presence of local inflammation resulting from the toxic effects of smoking products on the oral mucos

Recent outburst of the young star V1180 Cas

We report on the ongoing outburst of the young variable V1180 Cas, which is known to display characteristics in common with EXor eruptive variables. We present results that support the scenario of an accretion-driven nature of the brightness variations of the object and provide the first evidence of jet structures around the source. We monitored the recent flux variations of the target in the Rc, J, H, and K bands. New optical and near-IR spectra taken during the current high state of V1180 Cas are presented, in conjunction with H2 narrow-band imaging of the source. Observed near-IR colour variations are analogous to those observed in EXors and consistent with excess emission originating from an accretion event. The spectra show numerous emission lines, which indicates accretion, ejection of matter, and an active disc. Using optical and near-IR emission features we derive a mass accretion rate of ~3 E-8 Msun/yr, which is an order of magnitude lower than previous estimates. In addition, a mass loss rate of ~4 E-9 and ~4 E-10 Msun/yr are estimated from atomic forbidden lines and H2, respectively. Our H2 imaging reveals two bright knots of emission around the source and the nearby optically invisible star V1180 Cas B, clearly indicative of mass-loss phenomena. Higher resolution observations of the detected jet will help to clarify whether V1180 Cas is the driving source and to determine the relation between the observed knots.Comment: Accepted as Letter in A&A; 4 pages, 3 figure

Influence of ionic balance on the process of microcrystal AgBr (111) maturing

The research of the effect of photosensitivity level increase found in the process of maturing microcrystals AgBr with octahedron facets (111) without addition of sulphur containing additives (natural maturing) is carried out. It is stated that formation of sensitivity centres occurs during modification of AgBr (111) microcrystal form owing to difference of chemical potentials of microcrystal sides. Thus, the direct proofs of silver nature of sensitivity centres at maturing of AgBr (111) microcrystals in the conditions involved are obtained. The reasons of absence of natural maturing for AgBr microcrystals of a cubic facet (100) and flat AgBr (Т-МC) microcrystals are discussed

Situational analysis of socio-cultural interaction of states under conditions of globalization

The present article considers the possibilities of the paradigm of socio-cultural interaction when analyzing international relations. Traditional activity approaches in explaining this interaction are critically assessed, and the main situations of interstate interactions that have a socio-cultural importance are analyzed. The offered problematisation when studying global strategies of interstate relations in terms of socio-cultural interaction makes it possible to consider desirable strategies and scenarios for improving intercultural communication and international cooperation. Possible prospects on changing the basic benchmarks of the globalization processes based on socio-cultural interaction for its further humanization are outlined. The revealed mechanisms of the dynamics of socio-cultural interactions when moving from one situation of interaction to another, as well as the role of the cultural reality formed for this purpose and overcoming the one-sidedness of economism in international relations can provoke the researchers’ interest. The offered analysis of the situations of socio-cultural interaction enables the authors of the article to clarify some positive opportunities of the globalization in the overall civilization development and intercultural dialogue of all countries of the world community. The results given in the article in relation to studying the main reasons of the discrimination in interstate relations and offers on overcoming it by using the spiritual and moral potential of the world culture are also of great importance.peer-reviewe
