Mass measurements near the Z = N line with JYFLTRAP

Abstract

Masses of nuclides involved in astrophysical rp and ν p processes have to be known precisely in order to model these processes reliably. Mass excesses for 90 ground state and 8 isomeric states of neutron-deficient nuclides have been determined with a precision of better than 10 keV with the JYFLTRAP double Penning trap mass spectrometer at the Ion-Guide Isotope Separator On-Line facility in Jyväskylä. Highlights of the measurements related to nuclear astrophysics are given. Some of the measured isomers, such as 53 Co m , 90 Tc m , and 95 Pd m , and implications for the excitation energy of the 21 + isomer in 94 Ag are briefly discussed.

Quantifying and Engineering Mucus Adhesion of Probiotics

“…Like L. reuteri DSM 17938, its binding plateaus to its maximum relatively easily, reaching half maximum adhesion at OD A50 17.7 (Table 1). It has been suggested that biofilm-like aggregation is necessary for EcN colonization 72 and that mucoadhesion is influential in initial binding before other competitive mechanisms take over. Additionally, compared to pathogenic strains, commensal E. coli have more flexibility in their ability to perform metabolic shifts depending on the mono-and disaccharide carbon sources available from mucin glycans 73 .…”
