Trauma and Violence: The Human Remains from Pecos Pueblo and Forked Lightning
Pecos Pueblo, a Community situated in the Pecos River Valley, was inhabited AD 1325-1838. Forked Lightning, also situated in the Pecos River Valley, was inhabited from AD 1200-1425. Before the repatriation of the human remains of Pecos Pueblo and Forked Lightning to Jemez Pueblo, 1,127 individuals were reanalyzed for pathologies. This paper seeks to explore violence through time as indicated by...
متن کاملAnalysis of Transient Phenomena Due to a Direct Lightning Strike on a Wind Energy System
This paper is concerned with the protection of wind energy systems against the direct effects of lightning. As wind power generation undergoes rapid growth, lightning damages involving wind turbines have come to be regarded as a serious problem. Nevertheless, very few studies exist yet in Portugal regarding lightning protection of wind energy systems using numerical codes. A new case study is p...
متن کاملWhy snakes have forked tongues.
The serpent's forked tongue has intrigued humankind for millennia, but its function has remained obscure. Theory, anatomy, neural circuitry, function, and behavior now support a hypothesis of the forked tongue as a chemosensory edge detector used to follow pheromone trails of prey and conspecifics. The ability to sample simultaneously two points along a chemical gradient provides the basis for ...
متن کاملLightning Discharge and Fundamentals of Lightning Protection
A review of lightning protection concepts introduced by Benjamin Franklin (18th century) and James Clerk Maxwell (19th century) is given. Modern approaches to lightning protection of various structures and systems are discussed. In particular, the widely used electrogeometrical model (one version of which is the Rolling Sphere Method) and the topological shielding are presented. Bonding require...
متن کاملOscillation Phenomena in Isolated High Voltage Networks Caused by Lightning Strokes
Isolated networks are common practice for operating high voltage networks up to a small earth fault current defined by standards. The reason for choosing this type of network are the saving of the arc suppressing coils by coexistence of a self-healing grid in case of an earth fault. During the starting up of a 110-kV-isolated network long-time measurement were installed. During these measuremen...
