Radical Reduction of Epoxides Using a Titanocene(III)/Water System: Synthesis of ,-Deuterated Alcohols and Their Use as Internal Standards in Food Analysis

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 22 2010
Tania Jiménez
Abstract We describe a comprehensive study into the Cp2TiCl-mediated reductive epoxide ring opening using either water as a hydrogen source or deuterium oxide as a deuterium source. The remarkable chemical profile of this reaction allows access to alcohols with anti-Markovnikov regiochemistry from different epoxides. The use of D2O as a deuterium source leads to an efficient synthesis of ,-deuterated alcohols, including a deuterated sample of tyrosol, a bioactive compound contained in the leaves of the olive, which was successfully applied as an internal standard in food analysis.

Majority versus minority influence: when, not whether, source status instigates heuristic or systematic processing

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 3 2003
Robin Martin
Two experiments investigated the extent of message processing of a persuasive communication proposed by either a numerical majority or minority. Both experiments crossed source status (majority versus minority) with message quality (strong versus weak arguments) to determine which source condition is associated with systematic processing. The first experiment showed a reliable difference between strong and weak messages, indicating systematic processing had occurred, for a minority irrespective of message direction (pro- versus counter-attitudinal), but not for a majority. The second experiment showed that message outcome moderates when a majority or a minority leads to systematic processing. When the message argued for a negative personal outcome, there was systematic processing only for the majority source; but when the message did not argue for a negative personal outcome, there was systematic processing only for the minority source. Thus one key moderator of whether a majority or minority source leads to message processing is whether the topic induces defensive processing motivated by self-interest.

Two-beam multiplexed CARS based on a broadband oscillator,

JOURNAL OF RAMAN SPECTROSCOPY, Issue 8 2010
Kentaro Furusawa
Abstract A two-beam multiplexed coherent anti-Stokes Raman scattering (CARS) microscopy setup is demonstrated by using a broadband (BB) Ti:sapphire oscillator without using any specialty fibres. A well-defined spectral structure of the source leads to a delay-sensitive CARS measurement in two-colour CARS and also provides an efficient means of obtaining three-colour CARS signals combined with the dispersion compensation of the BB pulse. Our result implies that the background suppression is limited by the onset of the spurious signals caused by the different CARS process, qualitatively differing from what is typically observed in the CARS microscopy.

Language and nationality: the role of policy towards Celtic languages in the consolidation of Tudor power

NATIONS AND NATIONALISM, Issue 3 2001
Gillian Brennan
This article considers the attitude of the governing elite in sixteenth-century England to the minority languages spoken by subjects within their jurisdiction, concentrating on Cornish, Welsh and Irish. Perhaps influenced by the tendency of nineteenth-century nationalists to equate nationality and language, historians have assumed that Tudor governments were hostile to languages other than English and wished to suppress them. An examination of a variety of sources leads to the suggestion that this was not the case. There was a certain amount of apprehension in the political sphere in the 1530s but in the second half of the century cultural perception of languages dominated as attempts to spread the Protestant faith led to an encouragement of the range of vernaculars. The conclusion points to parallels between sixteenth-century and contemporary sympathy towards minority cultures in the context of the devolution debate. [source]
