Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Hydrochlorides, hydrates, hydronitrate, and an unanticipated hydrolysis product of famotidine

open access: yesActa Crystallographica Section C, EarlyView.
The structures of a new polymorph of famotidine hydrochloride, a famotidine hydrochloride hydrate, a new hydronitrate salt of famotidine, and an unexpected hydrolyzed complex of famotidine are reported. The famotidine hydrochloride hydrate and the hydrolyzed famotidine hydrochloride have Z′ values of 2 and 4, respectively.This article contributes to ...

A General Correlation between the Temperature-Dependent Solubility and Solute and Solvent Molar Masses in Binary n-Alkane Mixtures [PDF]

open access: yes, 2018
An increasingly popular solution in the oil-industry is long-distance sub-sea transportation of unprocessed well-streams. This will commonly expose the oil to temperatures significantly below the reservoir temperature, and possibly below the wax ...

General Split Helicity Gluon Tree Amplitudes in Open Twistor String Theory

open access: yes, 2010
We evaluate all split helicity gluon tree amplitudes in open twistor string theory. We show that these amplitudes satisfy the BCFW recurrence relations restricted to the split helicity case and, hence, that these amplitudes agree with those of gauge ...
