This work focuses on the seismic response of a volcano to different magmatic processes with the aim of sheding light on their driving physics as tracked by seismicity. We study seismic time series recorded at basaltic volcanoes and identify generic seismicity patterns characteristic of (i) inter-eruptive, (ii) reservoir feeding, (iii) reservoir leak, and (iv) dyke injection phases of volcanic a...

Dyke Davidoff Masson syndrome (DDMS) is characterized by seizures, facial asymmetry, contralateral hemiplegia and mental retardation. The characteristic radiologic features are cerebral hemiatrophy with homolateral hypertrophy of the skull and sinuses. We report a case of DDMS in an 18-month-old girl who presented with right sided focal seizures, hemiparesis of the same side, and delayed milest...

Refractory epilepsy is common in practice of neurology. Dyke-Davidoff-Masson Syndrome (DDMS) is one among the syndromes associated with refractory epilepsy. We have come across a case of Dyke-Davidoff-Masson syndrome while investigating a case of refractory epilepsy. When cerebral hemi atrophy is associated with the radiological features of osseous hypertrophy of calvarium, hyper-pneumatisation...

Dyke-Davidoff-Masson syndrome refers to atrophy of one cerebral hemisphere (hemiatrophy) due to an insult to the brain in fetal or early childhood period. This is an uncommon condition. We present a case of a nine month- old female presented with seizure and weakness of the right upper and lower extremities and subsequently computed tomography was performed and showed hemiatrophy of the left fr...

Sidney Campbell Dyke, founder of the A.C.P., celebrates his 80th birthday on 5 September 1966. We all wish him continued good health and many happy returns of the day. In the early years of the A.C.P. everyone who attended our meetings knew Dyke personally: one might almost say, intimately. But nowadays there must be many of our members who know him only by sight or by reputation. Therefore it ...

We investigated the impact of managed retreat on mercury (Hg) biogeochemistry at a site subject to diffuse contamination with Hg. We collected sediment cores from an area of land behind a dyke one year before and one year after it was intentionally breached. These sediments were compared to those of an adjacent mudflat and a salt marsh. The concentration of total mercury (THg) in the sediment d...

An accurate modeling of sophisticated geological units has a substantial impact on designing a mine extraction plan. Geostatistical simulation approaches, via defining a variogram model or incorporating a training image (TI), can tackle the construction of various geological units when a sparse pattern of drilling is available. The variogram-based techniques (derived from two-point geostatistic...

Sidney Campbell Dyke, founder of the Association of Clinical Pathologists and for many years a member of the Advisory Board of this Journal, died on 3 March. He was 88. Obituary notices have already been published in the British Medical Journal and Lancet (22 March). These have recorded Dyke's distinguished scholastic career, his wide range of scientific interests, his motives in founding the A...

The analysis of Anisotropy of Magnetic Susceptibility (AMS) is a powerful and rapid technique to examine the preferred orientations of mineral (magnetic) fabrics and can indicate the nature of a magma transport (vertical or lateral). The relationship between magnetic fabric and geometry of a dyke swarm enables us to understand magma emplacement processes. Depending on the mutual relationship of...
