Controls on the movement and composition of firn air at the West Antarctic Ice Sheet Divide
We sampled interstitial air from the perennial snowpack (firn) at a site near the West Antarctic Ice Sheet Divide (WAIS-D) and analyzed the air samples for a wide variety of gas species and their isotopes. We find limited convective influence (1.4–5.2 m, depending on detection method) in the shallow firn, gravitational enrichment of heavy species throughout the diffusive column in general agree...
متن کاملIs Sudden Hearing Loss Associated with Atherosclerosis?
Introduction: Sudden sensorineural hearing-loss (SSNHL) patients constitute approximately 2–3% of referrals to ear, nose and throat (ENT) clinics. Several predisposing factors have been proposed for this condition; one of which is vascular disorders and perfusion compromise. In this research the atherosclerotic changes and their known risk factors are studied in SSNHL patients. Materials and ...
متن کاملDrilling through salt Risks associated with drilling through salt

In recent years, an increasing number of oil and gas projects involving drilling through salt have been presented by different exploration companies. It is important for underwriters, lawyers, regulators, financiers and engineers to have a clear understanding...
متن کاملErosive Pressure Dermatitis Associated with Cardiac Pacemaker
Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...
متن کاملRapid intercontinental air pollution transport associated with a meteorological bomb
Intercontinental transport (ICT) of trace substances normally occurs on timescales ranging from a few days to several weeks. In this paper an extraordinary episode in November 2001 is presented, where pollution transport across the North Atlantic took only about one day. The transport mechanism, termed here an intercontinental pollution express highway because of the high wind speeds, was excep...
