Re: There is no evidence base for proposed dementia screening
(2013-01-04)While the cost and possible harm to the patient of current drugs may compromise a dementia screening programme, the potential benefits of dietary modification should be considered. Several well-conducted prospective trials ... -
[Re]searching [im]probable, [im]possible and [un]desirable design futures

Reaching the journey’s end : Reflections on the final phase of a problem-based learning group
(2009)This paper represents the final phase of a journey within a self-directed problem-based learning group occurring on the Doctorate in Clinical Psychology Programme based at the University of Hertfordshire. It provides ... -
The reaction Ge-70(alpha,gamma)Se-74 (p-process)

Reaction Mechanism Reduction for Ozone-Enhanced CH4/Air Combustion by a Combination of Directed Relation Graph with Error Propagation, Sensitivity Analysis and Quasi-Steady State Assumption
(2018-06-06)In this study, an 18-steps, 22-species reduced global mechanism for ozone-enhanced CH4/air combustion processes was derived by coupling GRI-Mech 3.0 and a sub-mechanism for ozone decomposition. Three methods, namely, direct ... -
The reaction of flavonoid metabolites with peroxynitrite
(2006-12-01)There is much interest in the bioactivity of in vivo flavonoid metabolites. We report for the first time the hierarchy of reactivity of flavonoid metabolites with peroxynitrite and characterise novel reaction products. ... -
Reaction rate sensitivity of 44Ti production in massive stars and implications of a thick target yield measurement for 40Ca(alpha,gamma)44Ti
(SISSA, 2011-01)The dynamic synergy between observation, theory, and experiment developed over many years around the field of gamma-ray astronomy has as its ultimate goal observations of specific radionuclides informing our understanding ... -
The reaction rate sensitivity of nucleosynthesis in type II supernovae
(1999-08-20)We explore the sensitivity of the nucleosynthesis of intermediate-mass elements (28 less than or equal to A less than or similar to 80) in supernovae derived from massive stars to the nuclear reaction rates employed in the ... -
Reaction rate sensitivity of the gamma-process path
(2005-07-25)The location of the (gamma,p)/(gamma,n) and (gamma,alpha)/(gamma,n) line at gamma-process temperatures is discussed, using recently published reaction rates based on global Hauser-Feshbach calculations. The results can ... -
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 ...
