Volcanic Plumbing and the Space Problem--Thermal and Geochemical Consequences of Large-Scale Assimilation in Ocean Island Development (1998)

O'Hara, M. J.

The decline and renaissance over the past 50 years of the concept that assimilation of crustal rocks may play a significant role in basalt genesis is reviewed and attention is drawn to the very...

Integrated Compositions of Perfect Fractional Liquid and Solid Products are Identical, with Respect to Ideal Trace Element Behaviour, to Simple Equilibrium (Batch) Products in Very Special Cases (1997)

O'Hara, M.J., Fry, N.

Partial melting of natural rocks is likely to proceed with the pooling of liquids which have been produced by a range of mass fractions of liquid development (O'Hara, 1985, 1995; Richter, 1986;...

The Highly Compatible Trace Element Paradox--Fractional Crystallization Revisited (1996)

O'HARA, M. J., FRY, N.

Field relations in dissected volcanic terrains and the internal evidence of persistent low-pressure cotectic character in erupted basalts point to the frequent and substantial modification of liquid...

Geochemical Effects of Small Packet Crystallization in Large Magma Chambers--Further Resolution of the Highly Compatible Element Paradox (1996)

O'HARA, M. J., FRY, N.

This is a study of the effect of solidifying a magma body by partial crystallization of a series of small packets of liquid, mixing the residual liquid into the main body of liquid before repeating...

Trace Element Geochemical Effects of Integrated Melt Extraction and 'Shaped' Melting Regimes (1995)

O'HARA, M. J.

The mixing (integration) of liquids obtained as different mass fractions of partial melting from source material of the same bulk composition, travelling along different mantle flow-lines through a...

Simultaneous measurement of left ventricular function and myocardial perfusion during a single exercise test: dual isotope imaging with gold-195 m and thallium-201 (1986)

LAHIRI, A., ZANELLI, G. D., O'HARA, M. J., BOWLES, M. J., JONES, R. I., CAVE, A. P. D., ...

The state of left ventricular function and myocardial perfusion are important determinants of prognosis in patients with coronary artery disease and information on both can be valuable for planning...

Objective evaluation of PY-108-068, a new calcium channel inhibitor for the treatment of chronic stable angina pectoris (1985)

O'HARA, M. J., KHURMI, N. S., BOWLES, M. J., RAFTERY, E. B.

PY-108–068 (PY) has calcium antagonist and coronary dilatory activity in animals, suggesting that it may be useful for the treatment of angina pec tor is. We have studied its effects in 19 patients...

Zoned Ultrabasic and Basic Gneiss Masses in the Early Lewisian Metamorphic Complex at Scourie, Sutherland (1961)

O'HARA, M. J.

The field relations and petrography of ultrabasic and basic gneisses which occur associated in small masses among banded granulite facies gneisses are described. The rocks are ascribed to reaction...

Detection of high risk coronary artery disease by thallium imaging.

O'Hara, M J, Lahiri, A, Whittington, J R, Crawley, J C, Raftery, E B

One hundred and three patients who underwent coronary arteriography were studied by thallium imaging and the results analysed by Bayesian principles to assess the usefulness of semiquantitative...

Changes in left ventricular function during exercise and their relation to ST segment changes in patients with angina.

O'Hara, M J, Jones, R I, Lahiri, A, Raftery, E B

The high count sensitivity of the non-imaging nuclear probe affords the possibility of measuring left ventricular ejection fraction continuously during short term interventions. The nuclear probe was...

Nicardipine in chronic stable angina: Objective assessment with computer-assisted exercise testing and ambulatory ST segment monitoring

Bowles, M. J., Khurmi, N. S., O'Hara, M. J., Raftery, E. B.

1 The efficacy of a new dihydropyridine derivative, nicardipine, with slow calcium channel blocking activity was evaluated objectively in three groups of patients with chronic stable angina, by...
