ABSTRACT Bringing together historical evidence, postcolonial fiction and memory work, this study recovers South Asian cultural attitudes towards interracial heterosexual romance from the margins of East African history. It asks why Black/brown intimacy was treated as taboo and denied legitimacy within South Asian diasporic communities in British‐ruled ...

The Timely Rise of a Teenage Reformer: Youth Revolt, Feminism and the Struggle for a ‘New Sexual Morality’ at the Dawn of the Spanish Second Republic

Wear behavior of different double-crown systems

Clinical Oral Investigations, 2012
The aim of this study was to evaluate aging effects on the retentive forces (RFs) of different double-crown systems. The effects of abutment height, inner- and outer-crown-material, taper angle, and artificial aging were analyzed.Inner (IC) and outer crowns (OC) (240), divided into four groups, 60 specimens each, were manufactured: A: IC = zirconia, OC

Double-armed crown ethers for calcium optical sensors

Talanta, 2009
This paper presents the characterization of optical sensing membranes for calcium based on ionophore-chromoionophore chemistry. Six different ionophores, 18-membered crown ether derivatives, were studied, coming from 18-crown-6 ether and 4,13-diaza-18-crown-6 ether to a series of double-armed crown ethers with different type of terminal groups.

Crown ethers containing trans double bonds

Tetrahedron Letters, 1981
Abstract The synthesis and spectroscopic properties of 18-crown-6-derivatives containing the E-α,β-dia1koxystilbene moiety as a ring member are described. These crown ethers are chiral but their complexing ability is drastically reduced as compared with the corresponding Z-isomers.

THE DOUBLE BELT SYSTEM FOR TREE CROWN STABILIZATION

Arboricultural Journal, 1993
Summary As tree crown failure along roadsides is an unacceptable hazard to both traffic and pedestrians, a new belt system for crown stabilization has been developed. The double belt “System Osnabruck” combines a stronger retaining belt, which carries the load and is linked to the bracing cable, and a weaker fastening belt, which is tightened loosely ...
