Measurements of the diffractive structure function F D(3) 2 (xIP , β, Q ), describing the process ep → eXY , are presented in the two kinematic regions 0.4 ≤ Q ≤ 5, GeV, 0.001 ≤ β ≤ 0.65, and 200 ≤ β ≤ 800 GeV, 0.4 ≤ β ≤ 0.9, both with xIP < 0.05, MY < 1.6 GeV and |t| < 1.0 GeV . Together with published measurements at intermediate Q, the data are compared with models based on QCD and Regge phe...

For the β phase of Ti-5553-type metastable β-Ti alloys, striations in transmission electron microscopy (TEM) bright- and dark-field images have been frequently observed but their origin has not been sufficiently investigated. In the present work, this phenomenon is studied in depth from the macroscopic scale by neutron diffraction to the atomic scale by high-resolution TEM. The results reveal t...

the aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles.this in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-tcp nanoparticles) and two control groups contai...

Amorfrutin C, a C-5 prenyl substituted amorfrutin, its allyl analog and an amorfrutin aldehyde derivate have been synthesized from common intermediate, which was prepared via biomimetic β, δ-diketo-dioxinone aromatization reaction.

The monobactam antibiotic aztreonam is used to treat cystic fibrosis patients with chronic pulmonary infections colonized by Pseudomonas aeruginosa strains expressing CTX-M extended-spectrum β-lactamases. The protonation states of active-site residues that are responsible for hydrolysis have been determined previously for the apo form of a CTX-M β-lactamase but not for a monobactam acyl-enzyme ...

The effect of the position of on-ramp and off-ramp i1 and i2, respectively, on the one dimensional-cellular automaton traffic flow behaviour, is investigated numerically. The injection rates at i1 and i2 are α0 and β0, respectively. However, in the open boundary conditions, with injecting and extracting rates α and β and using parallel dynamics, several phases occur; namely, low density phase (...
