Methods for the determination of carbon monoxide in blood based on spectroscopic analysis (Hartridge, 1922; Klendshoj, Feldstein, and Sprague, 1950) are accurate only when relatively high concentrations of carbon monoxide are present. The two most accurate methods in current use are the manometric method of Van Slyke and Salvesen (1919) and the volumetric method of Scholander and Roughton (1943...

Our aim in this investigation was to demonstrate the potential of the high-resolution electrospray ionization ion mobility spectrometry (ESI-IMS) technique as an analytical separation tool in analyzing biomolecular mixtures to pursue astrobiological objectives of searching for the chemical signatures of life during an in-situ exploration of solar system bodies. Because amino acids represent the...

The acute and chronic action of the oxidant gases ozone, nitrogen dioxide and oxygen on the morphological appearance of cells of the alveolar and bronchiolar epithelium is reviewed. Type I cells of the alveolar and ciliated cells of the bronchiolar epithelium appear to be sensitive targets for the oxidant gases. The degree of damage is influenced by age, nutritional status and the development o...

the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...

Guanidinoacetic acid (GAA) is a feed additive that promotes growth in animals, while maize (Zea mays L.) used for the mitigation of ruminal greenhouse gases. However, it unknown if GAA affects efficiency mitigating gases or there synergy between them. Therefore, objective this study was to evaluate vitro production total gas, methane (CH4), carbon monoxide (CO), and hydrogen sulfide (H2S), ferm...
