Analysis of urine electrolytes obtained during saturation excursion dives of four divers to depths equivalent to 800 and 1000 feet of sea water snowed in all cases during decompression an increase in urinary CO2 excretion and calcium excretionIn two subjects who developed symptoms of decompression sickness manifested in poorly localized muscle aches and stiffness of joints which did not respond...

Atmospheric carbon dioxide concentration ([CO2]) and other greenhouse gases have risen over the past few decades. If this continues, it could indirectly lead to increases in global temperature. Responses of grain legume crops (soybean, dry bean, peanut and cowpea) to elevated [CO2] and interactions with temperature are summarized. Our research shows that, in the absence of biotic (pests, diseas...

Carbon dioxide (CO2) is an established alternate angiographic contrast agent, which can be delivered by pump or hand injection. We describe a simple, safe and inexpensive hand injection system that delivers a known volume of CO2 at atmospheric pressure and prevents contamination with room air.

BACKGROUND AND STUDY AIMS The effect on abdominal pain of using carbon dioxide (CO2) for insufflation during endoscopic retrograde cholangiopancreatography (ERCP) has not been investigated. The present study aimed to compare CO2 insufflation with standard air insufflation with respect to the pain experienced during and after ERCP. In addition, we investigated the effect of CO2 insufflation on t...

The behavior of polymeric surfactant polyvinyl acetate (PVAC)-b-poly(1,1,2,2-tetrahydroperfluorooctyl acrylate) (PTAN) in supercritical carbon dioxide (CO2) was investigated using static and dynamic light scattering. We observed three regions on the phase diagram of the copolymer in supercritical CO2: (i) two-phase region at low CO2 density; (ii) solutions of spherical micelles at intermediate ...

[1] Iron fertilization of macronutrient-rich but biologically unproductive ocean waters has been proposed for sequestering anthropogenic carbon dioxide (CO2). The first carbon export measurements in the Southern Ocean (SO) during the recent SO-Iron Experiment (SOFeX) yielded 900 t C exported per 1.26 t Fe added. This allows the first realistic, data-based feasibility assessment of large-scale i...

Carbon sequestration refers to the process of transferring carbon dioxide (CO2) from the atmosphere into the soil. A significant fraction of carbon stored in the soil is stable and, consequently, can remain in the soil for decades or longer. This process of transferring or “sequestering” carbon from the atmosphere helps off-set emissions from combustion of fossil fuel and other human-related ac...

President Obama faces an old challenge of creating a national energy policy. That policy will be designed with multiple objectives in mind. After a year of record oil prices that added to U.S. economic troubles, some want an energy policy that will maintain lower energy prices. With nearly 150,000 troops still in Iraq and tensions raised with Russia over the Georgian invasion, some want an ener...

Due to urbanization, trees and plants which covered a great land mass of the earth and are an excellent carbon dioxide (CO2) absorber through photosynthesis are being replaced by several concrete based structures. It is therefore important to have these cement based structures absorb the large volume of carbon dioxide which the trees would have removed from the atmosphere during their useful li...
