Rifting, lithosphere breakup and volcanism: Comparison of magma-poor and volcanic rifted margins

Comparison of three commercially available activated charcoal canisters for passive scavenging of waste isoflurane during conventional rodent anesthesia.

Chronic, low-level exposure to waste anesthetic gases has been linked to increased incidences of neurologic and reproductive dysfunction, hepatic and renal toxicity, and neoplasia in humans. We have shown previously that one brand of activated charcoal canister (F/Air) used for passive scavenging of halogenated gases does not completely remove isoflurane during anesthetic protocols used in conv...

A breath of fresh air? Report of the 2003 British Thoracic Society Winter Meeting.

An overview of some of the key topics presented at the BTS Winter Meeting held in London on 3-5 December 2003.

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Fungal CO2 Sensing: A Breath of Fresh Air

Carbon dioxide levels are used by two fungal pathogens as a key signal to choose between the expression of environmental or virulence traits. Studies now reveal that the atypical fungal adenylyl cyclases are implicated in this decision.

Application of Solar Thermal Collectors to Improve the Energy Performance of the Fresh Air HVAC Systems

 In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...
