Chiral Separation of 3,5-Dinitrobenzoyl-(R,S)-Leucine in Process Intensified Extraction Columns [PDF]

open access: yes, 2015
The countercurrent liquid–liquid extraction of racemic 3,5-dinitrobenzoyl-(R,S)-leucine (DNB-(R,S)-Leu) was experimentally investigated using a process intensified extraction column (PIEC). This column (Øin = 15 mm; Hac = 1100 mm), in which both stirring

Software process modelling: Socio-technical perspectives [PDF]

open access: yes, 2022
S.111-139 : Ill., Lit.In this chapter we describe how the socio-technical systems (STS) approach has been applied to the software process, as well as attempts that have been made to simulate and model the process as a whole.

A New Method to Obtain Neutrons with Maxwellian Energy Distribution for Nuclear Astrophysics Study

open access: yesYuanzineng kexue jishu
To generate a neutron beam exhibiting a Maxwellian energy distribution with narrow emission angles for measuring the neutron capture reaction rates of the s-process nuclides, a monoenergetic 3.4 MeV proton beam produced by the tandem-accelerator in the ...

The origin and evolution of r- and s-process elements in the Milky Way stellar disk [PDF]

open access: yes, 2015
Knowledge of abundance ratios as functions of metallicity can lead to insights on the origin and evolution of our Galaxy and its stellar populations. We aim to trace the chemical evolution of the neutron-capture elements Sr, Zr, La, Ce, Nd, Sm, and Eu in

Direct Experiments of Neutron Capture on Stable and Unstable Isotopes for Stellar Nucleosynthesis Studies

open access: yesGalaxies
Neutron capture reactions provide essential nuclear physics input for modeling the synthesis of heavy elements in stars. The growing precision of stellar spectroscopy and isotopic measurements in presolar SiC grains now demands cross sections with ...

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.

From SuperTIGER to TIGERISS

open access: yesInstruments
The Trans-Iron Galactic Element Recorder (TIGER) family of instruments is optimized to measure the relative abundances of the rare, ultra-heavy galactic cosmic rays (UHGCRs) with atomic number (Z) Z ≥ 30. Observing the UHGCRs places a premium on exposure
