C02-induced kidney calcification
Schaefer, K. E., S. M. Pasquale, A. A. Messier, and H. Niemoeller. 1979. COrinduced kidney calcification. Undersea Biomed. Res. Sub. Suppl.: S143-S153.—Light microscopic examination of kidney tissue of guinea pigs exposed to 1.5% CO*, 2t% 02, and balance N2 for periods as long as 42 days and of rats exposed to the same CO: concentrations for up to 91 days showed that the incidence of focal kidn...
متن کاملEstimating Atmospheric Visibility Using General-Purpose Cameras
There is a growing interest in using general-purpose cameras to monitor a variety of physical phenomenon. In particular, a number of visibility camera networks have recently been deployed to complement traditional means for estimating atmospheric visibility. However, the images from these cameras have so far only been used to perform qualitative analysis. This work investigates image processing...
متن کاملThe Ni(0)—C02 System: Structure and Reactions of [Ni(PCy3)2(i/-C02)]
The reactions of a variety of bis(tricyclohexylphosphine)nickel species with C 0 2 have been studied. The product of the reaction is solvent dependent: in toluene the known complex [NiL2(/7 -C02)]-toluene (L = PCy3) is formed while in ether or pentane a binuclear complex [(NiL2)2(?;-C02)] results through the intermediacy of the solvent free species [NiL2(//-C02)] the structure of which has been...
متن کاملThe C02-Concentrating Mechanism and Photorespiration
Despite previous reports of no apparent photorespiration in C. , plants based on measurements of gas exchange under 2 versus 21% O, at varying [CO,], photosynthesis in maize (Zea mays) shows a dual response to varying [O,]. l h e maximum rate of photosynthesis in maize i s dependent on 0, (approximately 10Y0). lhis O2 dependence is not related to stomatal conductance, because measurements were...
متن کاملMultistation Estimating of Gps Signal Atmospheric Delays by Undifferenced Observations
Precise RTK positioning is usually performable only on short length bases, to limit distance correlated biases, as atmosphere and ephemerides. However, it is possible to recover some residual biases also over long distance using appropriate area models, improving the performances of long base RTK positioning up to 100 km base length. Permanent reference station networks are used to estimate the...
