The dependence of the scissors mode on the deformation in the Ce140-150 isotopes

WOS: 000174596500004In this study, using a rotational invariant microscopic model which is free from any adjustable parameter in the random phase approximation, the total M1 transition intensities of the 1(+) levels arising from the scissors mode for the Ce isotopes up to 4 MeV have been calculated and their dependence on the square of the deformation parameter delta(2) has been investigated. In the Ce isotopes, the dependence of the total B(M I) transition on delta(2) is linear as in the case of Nd and Sm isotopes. The separation of the rotational branch from the 1(+) states causes the fragmentation of the scissors mode and the collectivization of low-lying states

The effect of the neutron-proton pairing interaction on the excited 0+states in some deformed nuclei of the rare-earth region

WOS: 000081559800005In this work, the effect of the special type of neutron-proton (snp) interaction which was proposed by the authors previously, on the excited 0+ states in deformed even-even nuclei is investigated using the Quasiparticle Random Phase Approximation (QRPA) method. The results show that the energies of the 0+ states change and a new state depending on the value of the parameter q below the gap energy level appears

Deep petroleum occurrences in the lower Kura depression, south Caspian basin, Azerbaijan: an organic geochemical and basin modeling study

High sedimentation rates (as much as 2500 m/Ma) during Pliocene-Pleistocene, with a resultant undercompacted section as thick as 10,000 m, and lower than normal geothermal gradients are the main characteristics which have created all the means for generation and preservation of oil at deep layers in the Lower Kura Depression

Rotational-invariant model of the states with K-pi=1(+) and their contribution to the scissors mode

WOS: 000088668500004Within the Random-Phase Approximation the method of self-consistent determination of the isoscalar and isovector effective separable interactions restoring a broken symmetry of the deformed mean-field is given. The method allows to treat more rigorously without free parameters the properties of the scissors mode and is used to develop the rotational invariant microscopic model of the states with K-pi = 1(+). The spurious state separates out and has zero energy. An important consequence of this separation is the fragmentation of the scissors mode and the collectivization of the low-lying 1+ states. In addition to the isoscalar restoring interactions the consideration of the isovector restoring forces in calculations causes the splitting of the states with large B(M1) strength at low energy. The model contains a single parameter of isovector spin-spin interactions and it allows one to describe satisfactorily the fragmentation of the scissors mode and the dependence of the summed B(M1) strength on delta(2) and A in deformed nuclei

Phenotypic and genotypic characterization of lactic acid bacteria isolated from Azerbaijani traditional dairy products

Studied lactic acid bacteria (LAB) were isolated from two types of final ready-to-eat artisanal dairy products (cheeses – Agdas, Sheki and yogurts - Karabakh, Ganja and Baku) manufactured inAzerbaijan. The Agdas cheese belongs to the group of semi hard cheeses whilst the Sheki cheese belongs to hard cheeses. Both of cheeses were produced from cow’s milk without the addition of thestarter cultures. The Karabakh and Baku yogurts were produced from bovine’s milk and the Ganja yogurt from buffalo’s milk. Overall 378 isolates were collected from these dairy products and 296 ofthem were Gram-positive and catalase-negative. It was determined using biochemical tests and molecular methods that four species of LAB were mostly present in these cheeses: Lactobacillusplantarum, Lactobacillus brevis, Lactobacillus paraplantarum and Enterococcus faecium while in yogurts, Lactobacillus delbrueckii subsp. lactis, Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Enterococcus faecium dominated. Five enterococci were producers of antimicrobial compounds
