An Investigation of Void Fraction in the Stratified/Annular Flow Regions in Smooth, Horizontal Tubes [PDF]

, 1999
Refrigerants R134a and R410A have been used for void fraction measurements in smooth horizontal tubes with diameters between 4mm and 7mm. Quality and mass flux were varied from 5% to 90% and 75 kglm2-s to 700 kglm2-s, respectively.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Void fraction in simulated BWR fuel assembly. (I). Evaluation of cross-sectional averaged void fraction.

Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1988
Void measurement of a vertical (4×4) rod bundle has been conducted in a steam-water two phase flow using an advanced X-ray CT scanner and a large amount of rod bundle data was obtained. It was found from the results that the cross-sectional averaged void fraction data for a rod bundle could be correlated by the Drift-Flux model and that Zuber-Findlay ...

Photometric Properties of Void Galaxies in the Sloan Digital Sky Survey DR7 Data Release

, 2012
Using the sample presented in Pan:2011, we analyse the photometric properties of 88,794 void galaxies and compare them to galaxies in higher density environments with the same absolute magnitude distribution. In Pan et al.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

A synthetic benzoxazine dimer derivative targets c‐Myc to inhibit colorectal cancer progression

Molecular Oncology, EarlyView.
Benzoxazine dimer derivatives bind to the bHLH‐LZ region of c‐Myc, disrupting c‐Myc/MAX complexes, which are evaluated from SAR analysis. This increases ubiquitination and reduces cellular c‐Myc. Impairing DNA repair mechanisms is shown through proteomic analysis.
