Exploring the boundaries of the nuclear landscape : α-decay properties of 211Pa

2020

Employing the recoil ion transport unit (RITU) and a fusion-evaporation reaction, the α decay of 211Pa has been identified via the implantation-decay correlation technique through observation of chains up to four consecutive decays. An α-particle energy and half-life of 8320(40) keV and 3.8+4.6−1.4 ms, respectively, were measured, corresponding to favored α decay. In addition, more precise α-decay properties of 212Pa and 213Pa were obtained due to accumulated statistics. The present data were compared to those predicted by selected atomic mass models and it was used to estimate the possibility of observing proton emission from these isotopes. peerReviewed

Single-particle and collective excitations in the transitional nucleus 166Os

2021

The mean lifetimes of the lowest energy 2+, 8+ and 9− states in 166Os have been measured using the recoil distance Doppler-shift method in conjunction with a selective recoil-decay tagging technique. These measurements extend studies into the most neutron-deficient mass region accessible to current experimental methods. The B(E2; 2+ → 0+) = 7(2) W.u. extracted from these measurements is markedly lower than those observed in the heavier even-mass Os isotopes. The 8+ and 9− states yield reduced transition probabilities that are consistent with single-particle transitions. While these values may indicate a departure from collective structure, the level scheme and the underlying nuclear configu…

Data from: Climate determinants of breeding and wintering ranges of lesser kestrels in Italy and predicted impacts of climate change

2017

Climate warming would theoretically create conditions for the breeding range expansion of pseudo-steppe Mediterranean and long-distance migrant species and provide the possibility for these to overwinter in the same breeding areas. However, contemporary changes in rainfall regimes might have negative effects on the climate suitability and in turn, shrink species potential range. The lesser kestrel Falco naumanni is highly sensitive to rainfall oscillations and has recently extended its Italian breeding range towards northern latitudes and increasing its wintering records. We modelled the effects of temperature and rainfall on current and future climate suitability for lesser kestrels in bot…

Association of first trimester fetal heart rate and nuchal translucency with preterm birth.

2021

To evaluate whether first trimester fetal heart rate (FHR) and nuchal translucency (NT) associate with preterm birth (PTB).This was a comparative case-control study of 518 normal pregnancies with no history of PTB, of which 272 delivered at term (TB) and 246 progressed to spontaneous PTB prior to 37, 34, 32, and 28 weeks. Fetal heart rate (FHR) and NT values at the first-trimester scan were compared by means of univariable (Mann-Whitney) and multivariable logistic regression analysis considering hourglass membranes (HM) as the most severe PTB subgroup. Finally, severity trends for both parameters were investigated using correlations with gestational age (GA) at delivery and Kruskal-Walls te…

Maternal sleep duration and neonate birth weight: A population-based cohort study.

2021

Objective Sleep duration is an important health indicator. Our aim was to investigate the association between maternal sleep duration and infant birthweight. Methods The study included 2,536 mother-infant pairs of a Spanish birth cohort (2004-2006, INMA project). The exposures were questionnaire-based measures of sleep duration before and during pregnancy. The primary outcome was infant birthweight score (g) standardized to 40 weeks of gestation. Results In women sleeping less than 7 hours per day before pregnancy, each additional hour of sleep increased birthweight score by 44.7 g (p = 0.049) in the minimally-adjusted model, although findings were not statistically significant after consid…

First-trimester neck abnormalities: three-dimensional evaluation.

1998

In order to study the first trimester ultrasonographic differences between nuchal translucency and hygroma colli, we rescanned 25 fetuses (13 with nuchal translucency and 12 with hygroma colli) using transvaginal and three-dimensional ultrasonography, after obtaining a fetal karyotype report. Our objective was to test the premise that the different physiopathologic mechanisms of both processes would be reflected in detectable sonographic differences. Our retrospective analysis showed that the most striking ultrasonographic difference was the presence of bullae as well as greater irregularity, extent, and amplitude of the membrane in cases of hygroma colli. Fetuses with simple nuchal translu…
