Reaction rate sensitivity of Ti-44 production in massive stars and implications of a thick target yield measurement of Ca-40(alpha, gamma)Ti-44
(2010-06-01)We evaluate two dominant nuclear reaction rates and their uncertainties that affect Ti-44 production in explosive nucleosynthesis. Experimentally we develop thick target yields for the Ca-40(alpha, gamma)Ti-44 reaction at ... -
Reaction Rate Uncertainties and the nu p-Process
(American Institute of Physics (AIP), 2012)Current hydrodynamical simulations of core collapse supernovae find proton-rich early ejecta. At the same time, the models fail to eject neutron-rich matter, thus leaving the origin of the main r-process elements unsolved. ... -
Reaction rates and nuclear properties relevant for nucleosynthesis in massive stars and far from stability
(World Scientific Publishing, 2003)Explosive nuclear burning in astrophysical environments produces unstable nuclei which again can be targets for subsequent reactions. In addition, it involves a large number of stable nuclides which are not fully explored ... -
Reaction synthesis of carbide-reinforced cast iron

Reaction-mechanisms for astrophysically relevant nuckear processes
(1993-07)The different reaction mechanisms and models applied to nuclear reactions at thermonuclear energies are discussed. As an example we consider the reaction Li-8(alpha,n)B-11. -
Reaction-rates for Sm-146 production in supernovae
(1995-09-20)Correlations of the Nd-142/Nd-144 ratio with the Sm/Nd ratio in some meteorites have been previously explained by the alpha-decay of long-lived Sm-146. In order to account for these observations, a necessary production ... -
Reactions to insanity : a study of stigma, discrimination and labelling in relation to present and former psychiatric patients
(University of Hertfordshire, 1992)The thesis is organised around an empirical investigation of the relationship between residents of a Hertfordshire village and people who are, or who have been, patients at a nearby psychiatric hospital, some of whom ... -
Reactive Halogens in the Marine Boundary Layer (RHaMBLe) : the tropical North Atlantic experiments
(2010)The NERC UK SOLAS-funded Reactive Halogens in the Marine Boundary Layer (RHaMBLe) programme comprised three field experiments. This manuscript presents an overview of the measurements made within the two simultaneous remote ... -
Reactivity controlled compression ignition engine: Pathways towards commercial viability
(2021-01-15)Reactivity-controlled compression ignition (RCCI) is a promising energy conversion strategy to increase fuel efficiency and reduce nitrogen oxide (NOx) and soot emissions through improved in-cylinder combustion process. ... -
Readiness to change drinking behaviour among heavy-drinking university students in England
(2014-01-01)There is growing literature on possible ways of reducing alcohol consumption and alcohol -related harm among university students (Larimer and Cronce, 2002; Siegers and Carey, 2010). However, interventions with this aim ... -
Reading "24" : TV against the clock
(I. B. Tauris, 2007)When the series of ‘24’ began screening in 2001, Time magazine branded it one of the 'Best Television Events of the Decade'. The series has since made itself known as both pioneering and controversial which has changed the ... -
Reading Graphic Design in Cultural Context
(Bloomsbury Publishing, 2019-02-07)Reading Graphic Design: •Is a much needed examination of graphic design in the expanded field •Forms an introduction to writing critically about graphic design through twelve chapters providing exemplary analyses of the ... -
Reading the mind in the touch: Neurophysiological specificity in the communication of emotions by touch
(2018-07-31)Touch is central to interpersonal interactions. Touch conveys specific emotions about the touch provider, but it is not clear whether this is a purely socially learned function or whether it has neurophysiological specificity. ... -
Readings of Wittgenstein's On Certainty
(Palgrave Macmillan, 2007)On Certainty is Wittgenstein's third masterpiece, and arguably the greatest contribution to epistemology since Kant's Critique of Pure Reason. The major aim of this collection - the first devoted exclusively to On Certainty ...
