An effective Nuclear Model: from Nuclear Matter to Finite Nuclei

The momentum and density dependence of mean fields in symmetric and asymmetric nuclear matter are analysed using the simple density dependent finite range effective interaction containing a single Gaussian term alongwith the zero-range terms. Within the formalism developed, it is possible to reproduce the various diverging predictions on the momentum and density dependence of isovector part of the mean field in asymmetric matter. The finite nucleus calculation is formulated for the simple Gaussian interaction in the framework of quasilocal density functional theory. The prediction of energies and charge radii of the interaction for the spherical nuclei compares well with the results of other effective theories.Comment: 10 pages, 3 figures, 2 tables, To appear in the Proceedings of the 11th International Conference on Nucleus-Nucleus Collisions (NN2012), May 27-June 1, 2012, San Antonio, Texas, US

Contributing factors and quality of life among women with abnormal uterine bleeding

Background: Abnormal uterine bleeding (AUB) is one of the most common debilitating menstrual problems and it has a major impact on quality of life.Methods: A explorative research design was adopted to study the contributing factor and quality of life. Hundred and fifty (150) women with AUB were selected purposively from gynecology OPD of IMS and SUM Hospital, Bhubaneswar, Odisha. The tools used for the study were 1) the socio-demographic questionnaire, 2) questionnaire to assess the contributing factors and 3) WHOQOL-BREF questionnaire to assess the quality of life. The data were analyzed using descriptive and inferential statistics.Results: Highest percentage of women (46.66%) were aged between 46 and 50. Majority of women had mental stress (72.67%) and were non-vegetarian (66%). Half of the (50.66%) women had a family history of AUB, and 16.66% of women had a family history of malignancy. Majority (76.66%) of women were diagnosed with medical conditions and among the highest percentage (27.84%) of them had thyroid diseases. The overall quality of life score was 65.08±11.19 and the social relationship domain (38.72±7.11) was more affected and the environmental domain (75.94±4.12) was least affected.Conclusions: Various factors are involved in the development of abnormal uterine bleeding.  There is a need for awareness about the contributing factors and prevention of AUB among reproductive-age women.

Raman spectra and Magnetization of all-ferromagnetic superlattices grown on (110) oriented SrTiO3

Superlattices consist of two ferromagnets La0.7Sr0.3MnO3(LSMO)and SrRuO3(SRO) were grown in (110)-orientation on SrTiO3(STO) substrates. The x-ray diffraction and Raman spectra of these superlattices show the presence of in-plane compressive strain and orthorhombic structure of less than 4 u.c. thick LSMO spacer,respectively. Magnetic measurements reveal several features including reduced magnetization, enhanced coercivity, antiferromagnetic coupling, and switching from antiferromagnetic to ferromagnetic coupling with magnetic field orientations. These magnetic properties are explained by the observed orthorhombic structure of spacer LSMO in Raman scattering which occurs due to the modification in the stereochemistry of Mn at the interfaces of SRO and LSMO
