Preliminary study of feasibility of an experiment looking for excited state double beta transitions in tin

An attempt to study the feasibility of a new experiment to search for double beta decay in $^{112}$Sn and $^{124}$Sn was carried out by using ultra-low background HPGe detector (244 cm$^{3}$) inside the Gran Sasso National Laboratory (LNGS) of the INFN (Italy). A small sample of natural Sn was examined for 2367.5 h. The radioactive contamination of the sample has been estimated. The data has also been considered to calculate the present sensitivity for the proposed search; half-life limits $\sim$ $10^{17} - 10^{18}$ years for $\beta^{+}$EC and EC-EC processes in $^{112}$Sn and $\sim$ $10^{18}$ years for $\beta^{-}\beta^{-}$ transition in $^{124}$Sn were measured. In the last section of the paper the enhancement of the sensitivity for a proposed experiment with larger mass to reach theoretically estimated values of half-lives is discussed.Comment: 20 pages, 11 figures, 4 tables, accepted for publication in NIMA (in press

Short primiparous women are at an increased risk for gestational diabetes mellitus

Objectives: Both short stature and adiposity are risk factors for gestational diabetes mellitus (GDM). The aim of this study was to simultaneously evaluate the importance of stature and degree of adiposity on development of GDM in primiparous women. Study design: Longitudinal cohort study. Methods: In the city of Vantaa, Finland, between 2009 and 2015, all together 7750 primiparous women without previously diagnosed diabetes mellitus gave birth. Of these, 5223 women were >= 18 years of age with information on height, weight, and complete data from a 75 g 2-h oral glucose tolerance test composing the study participants of this study. Results: A 155-cm tall woman with a body mass index (BMI) of 25.5 kg/m(2) had a similar risk for GDM as a 175-cm tall woman with a BMI of 27.1 kg/m(2). Women shorter than 159 cm had the highest prevalence of GDM, 28.7%, whereas women with height between 164 and 167 cm had the lowest prevalence of GDM, 19.9% (P <0.001). Height was inversely and significantly associated with both 1- and 2-h glucose values (both P <0.001). Conclusions: To avoid over diagnosis of GDM, an unbiased strategy is needed to determine and diagnose GDM in women with different stature and degree of adiposity.

Chromomagnetism in nuclear matter

Quarks are color charged particles. Due to their motion there is a strong possibility of generation of color magnetic field. It is shown that however hadrons are color singlet particles they may have non-zero color magnetic moment. Due to this color magnetic moment hadrons can show color interaction. In this paper we have studied the chromomagnetic properties of nuclear matter.Comment: 6 pages, 1 figure, accepted for publication in Int. J. Theor. Phy

A note on the Gauss decomposition of the elliptic Cauchy matrix

Explicit formulas for the Gauss decomposition of elliptic Cauchy type matrices are derived in a very simple way. The elliptic Cauchy identity is an immediate corollary.Comment: 5 page

Impact of maternal income on the risk of gestational diabetes mellitus in primiparous women

Aims Findings concerning the impact of socio-economic status on the risk of gestational diabetes mellitus (GDM) are inconclusive and little is known about the simultaneous impact of income and educational attainment on the risk of GDM. This study aims to assess the impact of maternal prepregnancy income in combination with traditional GDM risk factors on the incidence of GDM in primiparous women. Methods This is an observational cohort study including 5962 Finnish women aged >= 20 years from the city of Vantaa, Finland, who delivered for the first time between 2009 and 2015, excluding women with pre-existing diabetes mellitus. The Finnish Medical Birth Register, Finnish Tax Administration, Statistics Finland, Social Insurance Institution of Finland and patient healthcare records provided data for the study. We divided the study population according to five maternal income levels and four educational attainment levels. Results Incidence of GDM decreased with increasing income level in primiparous women (P <0.001 for linearity, adjusted for smoking, age, BMI and cohabiting status). In an adjusted two-way model, the relationship was significant for both income (P = 0.007) and education (P = 0.039), but there was no interaction between income and education (P = 0.52). Conclusions There was an inverse relationship between both maternal prepregnancy taxable income and educational attainment, and the risk of GDM in primiparous Finnish women.Peer reviewe

Rotational Bands and Electromagnetic Transitions of some even-even Neodymium Nuclei in J-Projected Hartree-Fock Model

Rotational structures of even-even $^{148-160}$Nd nuclei are studied with the self-consistent deformed Hartree-Fock (HF) and angular momentum (J) projection model. Spectra of ground band, recently observed $K=4^{-}$, $K=5^{-}$ and a few more excited, positive and negative parity bands have been studied upto high spin values. Apart from these detailed electromagnetic properties (like E2, M1 matrix elements) of all the bands have been obtained. There is substantial agreement between our model calculations and available experimental data. Predictions are made about the band structures and electromagnetic properties of these nuclei. Some 4-qasiparticle K-isomeric bands and their electromagnetic properties are predicted.Comment: 20 page
