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

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.

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 ...

Weak s-PROCESS Irradiations

open access: yesThe Astrophysical Journal, 1972
We calculate the overabundances of rare neutron-rich species produced when seed nuclei between silicon and nickel are exposed to small neutron irradiations in order to ascertain whether those species may owe their natural abundances to such a cause, Particular attention is given to 54Cr and 58Fe, two relatively prominent neutron-rich species that have ...

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

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Potential Industrial Applications and Commercialization of Microalgae in the Functional Food and Feed Industries: A Short Review

open access: yesMarine Drugs, 2019
Bioactive compounds, e.g., protein, polyunsaturated fatty acids, carotenoids, vitamins and minerals, found in commercial form of microalgal biomass (e.g., powder, flour, liquid, oil, tablet, or capsule forms) may play important roles in functional food ...

NuGrid: s process in massive stars [PDF]

open access: yesProceedings of 10th Symposium on Nuclei in the Cosmos — PoS(NIC X), 2009
The s-process production in massive stars at very low metallicities is expected to be negligible due to the low abundance of the neutron source 22Ne, to primary neutron poisons and decreasing iron seed abundances. However, recent models of massive stars including the effects of rotation show that a strong production of 22Ne is possible in the helium ...
