Observations of the relationship between linear or planar features on either side of dykes usually form the basis of a field determination of their mode of emplacement, although it is known that sections oblique to planar features may lead to conflicting results. In Eastern Tasmania only rarely are examples encountered where dyke wall-rock units are of use. However, dyke wall irregularities are...

A trial fibrillation (AF) is the most common cardiac arrhythmia. The preferred therapy for AF is sustained sinus rhythm control; however, the efficacy of currently used antiarrythmic drugs is limited by adverse side effects resulting from both a lack of ion channel selectivity and nonspecific ventricular activity. The role of the voltage-gated potassium channels in atrial myocyte repolarization...

Pine wilt disease (PWD) has caused significant Masson pine mortality in the Three Gorges reservoir region in central China. In this study, five uniform Masson pine stand types infected by PWD were selected and surveyed on slopes and aspects with similar environmental conditions. In sites that had been infected, soil bulk density was reduced, and the difference among the groups was statistically...

It is now more than 50 years since, in 1927, Sydney Campbell Dyke banded together the growing number of pathologists to form the British Pathologists' Association, which later became known as The Association of Clinical Pathologists. Dyke had a wide-ranging interest in medicine, unlike some of his successors, who have relinquished their clinical affiliations and have retired to the confines of ...

Introduction The narrow-leaved cattail wetland (Hopfensperger and Engelhardt 2007) known as Dyke Marsh formally became a land holding of George Washington Memorial Parkway (GWMP, a unit of the national park system) in 1959, along with a congressional directive to honor a newly-let 30-year commercial sand and gravel dredge-mining lease at the site (Litwin et al. 2013; Figure 1). Dredging continu...

Ignimbrites within calderas host intrusions with hazardous and/or economically significant hydrothermal systems. The Hvítserkur ignimbrite at Breiðuvík caldera, north-eastern Iceland, is intruded by basaltic dykes. Our data show that the immediately adjacent to dyke hard, dark-coloured, recrystallised quartz, plagioclase, and alkali feldspar a low permeability porosity frequent macrofractures. ...

David Masson was born in Edmonton, Alberta, Canada on February 6th, 1937. His family lived there until he was 12 when, shortly after his father’s death, David and his mother moved to Winnipeg. David earned a B. Sc. from University of Manitoba in 1958, and an M. Sc. from McGill University the following year. His thesis was entitled Scattering of λ Particles by Nucleons and was completed under th...
