The energies of the excited states in very neutron-rich (42)Si and (41,43)P have been measured using in-beam gamma-ray spectroscopy from the fragmentation of secondary beams of (42,44)S at 39A MeV. The low 2(+) energy of (42)Si, 770(19) keV, together with the level schemes of (41,43)P, provides evidence for the disappearance of the Z=14 and N=28 spherical shell closures, which is ascribed mainl...
Objective: To evaluate and identify determinants of health related quality of life (HRQoL) during pregnancy. Methods: In this descriptive exploratory study in sixty-four nulliparous pregnant women, completed the questionnaire: HRQoL (Colombian standard version of the Medical Outcome Study Short-Form Health Survey -SF12v2-), and sociodemographic determinants (i.e., age, place of origin, educatio...
We show that boundary conditions in topological open string theory on Calabi-Yau manifolds are objects in the derived category of coherent sheaves, as foreseen in the homological mirror symmetry proposal of Kontsevich. Together with conformal field theory considerations, this leads to a precise criterion determining the BPS branes at any point in CY moduli space, completing the proposal of Π-st...
Heterotopic pregnancy is defined as intrauterine and extrauterine pregnancy entity coexisting simultaneously and which has been on the rise in recent years with the development of assisted reproductive techniques. We report 4 cases of heterotopic pregnancy, three of them resulting from assisted reproductive technologies and a spontaneous case. We also describe the methods used for diagnosis, th...
The cross-section of the thermal neutron capture 41 Ar(n,γ) 42 Ar( t 1/2 =32.9 y) reaction was measured by irradiating a 40 Ar sample at high-flux reactor Institut Laue-Langevin (ILL) Grenoble, France. signature two-neutron has been observed measuring growth curve and identifying 1524.6 keV γ-lines shorter-lived K(12.4 h) β − daughter Ar. Our preliminary value cross section is 240(80) mb 25.3 m...
