Circling seizures

Twelve cases with circling seizures are presented with their clinical, electroencephalographic and radiological findings. Four patients had symptomatic partial epilepsy, five had cryptogenic partial epilepsy, and the remaining three had idiopathic generalized epilepsy. Three of the patients with symptomatic partial epilepsy had frontal lesion, and one had parito-occipital lesion. Turning direct...

Plants circling in outer space.

Plants circling in outer space

Plants do not grow in a strict linear manner, rather they circumnutate. That is, they exhibit an oscillatory or helical growth pattern around an axis. Circumnutation is readily apparent in vines such as morning glory or grape (Fig. 1), but in fact it is nearly ubiquitous in plants. Circumnutation occurs in almost all plant organs throughout all stages of development (Johnsson, 1997; Larson, 200...

SCADA Security - Slowly Circling a Disaster Area

SCADA (Supervisory Control And Data Acquisition) networks control much of the industrialised nations production and supply complexes. Various government reports and investigations have highlighted the vulnerability of these systems. Many of these systems are on private networks which are increasingly being connected to systems that are accessible from other networks such as the Internet. SCADA ...
