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 ...

The cyclopoid copepod Dioithona oculata forms swarms in water <30 cm deep among prop roots of red mangroves (Rhizophora mangle) which fringe protected areas of two iagoona! cays. Twin Cays. Belize. During 7 of 8 months surveyed by in situ ol^servation, swarms were present but differed in size from small cylindrical swarms (5-10 cm diameter) to bands extending up to 1200 m. Swarms were never obs...

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...

Reproductive swarms of honeybees are faced with the problem of finding a good site to establish a new colony. We examined the potential effects of swarm size on the quality of nest-site choice through a combination of modelling and field experiments. We used an individual-based model to examine the effects of swarm size on decision accuracy under the assumption that the number of bees actively ...

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...
