Barium stars and the s-process
The Astrophysical Journal, 1980 Theoretical s-process calculations are presented. Isotopic abundances are summed, so that atomic number Z becomes the independent variable. This form of representation of the calculations has distinct advantages in the interpretation of stellar data, since one generally does not have isotopic information.

Broad levels in 17 O and their relevance for the astrophysical s process [PDF]
, 2015 Levels in $^{17}$O affect the astrophysical s-process in two opposite ways. The neutron production is enhanced by resonances in the $^{13}$C($\alpha$,$n$)$^{16}$O reaction at excitation energies around 7 MeV in $^{17}$O, and the number of available ...

The Impact of Process Safety on Productivity and the Bottom Line [PDF]
, 1998 PresentationHow does process safety impact productivity and the bottom-line? A total safety process. Kvaerner utilizes aspects of Process Safety Management to control the safety quality of its process design. PSM also drives many aspects of construction,

Dynamic failure analysis of process systems using neural networks [PDF]
, 2017 Complex and non-linear relationships exist among process variables in a process operation. Owing to these complex and non-linear relationships potential accident modelling using an analytical technique is proving to be not very effective.

22Ne(α,n)25Mg at the INFN Bellotti Ion Beam Facility
GalaxiesNeutron capture reactions are the main contributors to the synthesis of heavy elements through the s-process. 22Ne(α,n)25Mg is the main neutron source in stars, together with 13C(α,n)16O.

Probing astrophysically important states in the Mg 26 nucleus to study neutron sources for the s process [PDF]
, 2015 Background: The ²²Ne(α,n) ²⁵Mg reaction is the dominant neutron source for the slow neutron capture process (s process) in massive stars, and contributes, together with C¹³(α,n)O¹⁶, to the production of neutrons for the s process in asymptotic giant ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Energy consumption and carbon footprint of perovskite solar cells
Energy Reports, 2022 Recently, perovskite solar cells (PSCs) emerged and promise to break the prevailing solar energy paradigm by combining both low-cost and high-efficiency.

Chemical abundance study of two strongly s-process enriched post-AGB stars in the LMC: J051213.81-693537.1 and J051848.86-700246.9 [PDF]
, 2015 Context: This paper is part of a larger project in which we study the chemical abundances of extra-galactic post-AGB stars with the ultimate goal of improving our knowledge of the poorly understood AGB third dredge-up mixing processes and s-process ...
