Pneumorachis after cocaine sniffing
Air in the epidural space is called pneumorachis. The usual mechanism of pneumorachis is air diffusion from the mediastinal tissue layers through the inter-vertebral foramen. Alternatively, air can diffuse directly after spine traumas (e.g., blunt deceleration with vertebral dislocation) or medical procedures. Several mechanisms could explain pneumomediastinum and pneumorachis after cocaine sni...
متن کاملGood Bugs Vs . Bad Bugs
Control of micro-organisms during completion of hydraulically fractured wells is a significant component in successful development of a production system. Detrimental bacteria—“bad bugs”—such as sulfate-reducing bacteria (SRB) introduced into the reservoir during drilling or completion, can facilitate biogenic sulfide production, resulting in souring of production fluids and gas, iron sulfide f...
متن کاملSniffing IEEE 802.11 Mobility
Portable computing devices have transformed mobility into a serious concern to network researchers. Existing mobility measurement data have been very useful to the community, but achieve their limitations because they apply only to specific contexts (e.g. university campuses and conference venues). This paper advocates using Wi-Fi sniffing to study mobility in other environments. This approach ...
متن کاملOdor localization and sniffing.
For humans, the localization of an odorant seems only possible if the odorant also stimulates the trigeminal nerve. There is, however, some evidence that active sniffing may affect this ability and facilitate the localization of pure odorants. Therefore, we tested the ability of 40 subjects to localize a pure odorant and a mixed olfactory/trigeminal stimulus under 2 stimulation conditions: eith...
متن کاملSniffing behaviours in guenons.
In Old World monkeys (OWM), the olfactory sense is thought to be less important than in other primate taxa. However, during the last decade experimental studies have shown that OWM possess much better olfactory capabilities than suspected. Here, we investigate for the very first time sniffing behaviours in three guenon species (Diana, de Brazza's and owl-faced monkeys) held in the Leipzig Zoo, ...
