Paired micropuncture experiments were carried out in plasma-replete volume-expanded rats to examine the acute effects of 1-desamino-8-D-arginine vasopressin (dDAVP) on urinary acidification and tubular handling of bicarbonate and chloride. No effect was detected on the fractional absorption of water, total CO2, and chloride at end-proximal and early distal sites of superficial nephrons in intac...

Recent studies of ice cores from Greenland and Antarctica have proven that both temperature and CO2 content of the earth’s atmosphere followed a regular 100,000 year cycle of change and that they are closely correlated. Moreover, the observed increase of CO2 in the atmosphere exceeds the predicted values extrapolated from historical data. Other than industrialization and rapid urbanization, geo...

CO2 injected in the reservoir of McElroy Field, TX, for a CO2 ̄ood was in the supercritical state. Supercritical CO2 ̄uid is capable of extracting light and intermediate hydrocarbons from rocks but is unable to extract heavy hydrocarbons and asphaltics. Therefore, plugging of asphaltics in reservoir rocks and a consequent reduction in injectivity and recovery may result when CO2 only is used in ...

Global measurement of atmospheric CO2 concentration from space is greatly desired for global and regional carbon budget studies. The biggest challenge for CO2 remote sensing from space is to achieve the high-precision science measurement requirement (~ 1 ppmv or 0.3% on regional scales) so that the satellite measurements will be able to remarkably reduce current large uncertainties about carbon...

In spite of the importance of the potato as a food, little is known about the effect of environmental factors on photosynthesis in the plant. Studies with several other crops (1, 12, 16, 23, 24) have not only added to the knowledge of photosynthesis but have aided in understanding certain responses of these crops to environmental variations. VERDUIN and LooMIs (24) and GABRIELSON (10) have show...

CO2 capture, use, and storage have been identified as significant strategies for reducing greenhouse gas emissions induced by the usage of fossil fuels. The current review focuses on concepts post-combustion capture technologies based absorption mechanisms. Among all other developed technologies, researchers proposed most mature carbon technology industrial-scale application. Absorption-based c...

Carbon dioxide (CO2) levels in the atmosphere and surface ocean are rising at an unprecedented rate due to sustained and accelerating anthropogenic CO2 emissions. Previous studies have documented that exposure to elevated CO2 causes impaired antipredator behavior by coral reef fish in response to chemical cues associated with predation. However, whether ocean acidification will impair visual re...

The development of catalytic methods for chemical transformation of CO2 into useful compounds is of paramount importance from a standpoint of C1 chemistry and so-called green chemistry. The kinetic and thermodynamic stability of CO2 molecule presents significant challenges in designing efficient chemical transformations based on this potential feedstock. In this context, efforts to convert CO2 ...
