Molecular nitrogen (N(2)) and carbon monoxide (CO) have the two strongest bonds in chemistry and present significant challenges in developing new transformations that exploit these two abundant feedstocks. At the core of this objective is the discovery of transition-metal compounds that promote the six-electron reductive cleavage of N(2) at ambient temperature and pressure and also promote new ...

A comparison between the CO and HI Tully-Fisher relation for a sample of 30 Virgo galaxies shows no significant difference concerning the intrinsic scatter. The distance moduli from both relations after correcting for the sample incompleteness bias agree within the errors and also show no significant difference with previous studies of the Virgo cluster using a complete sample. The CO total lin...

A systematic survey was undertaken, of the effects of carbon monoxide and hydrogen cyanide (in the presence of 20 per cent oxygen), in darkness and light, on the relative rates of respiration, mitosis, and interphase in pea root tips. The inhibition of respiration by carbon monoxide was light-sensitive, but the inhibition by hydrogen cyanide was light-stable. The inhibitions were presumably due...

background: this toxicological investigation involves a report on the death of four ‎occupants of a sport utility vehicle on one of the major busy federal roads of nigeria ‎where they were held for up to three hours in a traffic jam while the car was steaming.‎ methods: autopsy was executed using the standard procedure and toxicological ‎analysis was done using simple spectrophotometric method ...

the aim of this study was to define the electrocardiogram (ecg) changes following the moderate to severe co intoxication in rats, and also evaluating the effect of erythropoietin (epo) on observed cardiac disturbances. the growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. wistar rats were exposed...

Acknowledgements Thank you to everyone who helped and supported me in completing this thesis! First, of course, thanks to Professor Stark for inviting me to SOLEIL for my independent study last year, for keeping me on as a thesis student, and for a second trip to France (even though I am less useful because I don't speak any French). Your guidance and patience in teaching me spectroscopy, basic...

BACKGROUND Unexplained or primary pulmonary hypertension results in an obliteration and obstruction of resistance pulmonary arteries. In these patients gas exchange is impaired and the measurement of gas transfer for carbon monoxide is usually reduced. This has been thought to represent a reduction in pulmonary alveolar capillary blood volume (Vc). A single breath test, measuring simultaneously...

Speciated volatile organic compound (VOC) and carbon monoxide (CO) measurements from the Marylebone Road site in central London from 1998 through 2008 are presented. Long-term trends show statistically significant decreases for all the VOCs considered, ranging from 3% to 26% per year. Carbon monoxide decreased by 12% per year over the measurement period. The VOC trends observed at the kerbside ...

The title compound, [Ni(C(5)H(9)N)(3)(CO)], was prepared from Ni(CO)(4) and a tenfold excess of tert-butyl isocyanide. It crystallizes with two symmetry-independent mol-ecules per asymmetric unit. The central Ni atom of each independent mol-ecule has a nearly perfect tetra-hedral coordination environment, comprising one carbon monoxide and three isocyanide ligands. The title compound is the fir...
