background: carbon monoxide (co) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. magnetic resonance imaging (mri) has a well-recognized role in assessment of the severity of brain damage caused by co poisoning. in this study, we aimed to present and analyze the structural abnormalities in the brain mri and especially in diffusion weighted mri (dwi) images in ...
We present measurements of the emission from the centers of fifteen spiral galaxies in the P1 − 3 P0 [CI] fine-structure transition at 492 GHz. Observed galaxy centers range from quiescent to starburst to active. The intensities of neutral carbon, the J=2–1 transition of CO and the J=4–3 transition of CO are compared in matched beams. Most galaxy centers emit more strongly in [CI] than in CO, c...
Considering the vital importance of air and the increasing trace of its contaminating factors, it is necessary to study the contaminating factors in order to be aware of the existing situation. The phenomenon of air pollution is one of the most important problems in many parts of Iran, due to several reasons, increasing the amount of it day by day. Carbon monoxide is one of the most dangerous p...
The adsorption/absorption of hydrogen and the adsorption of carbon monoxide by niobium foils, at room temperature, was studied using thermal desorption spectroscopy. Two hydrogen desorption peaks were observed with a maximum at 404 and 471 K. The first hydrogen desorption peak is regarded as hydrogen desorbing from surface sites while the second peak, which represents desorption from surface si...
Transient grating spectroscopy was applied to measurements of sound velocity and thermal diffusivity in binary mixture solutions of carbon dioxide (CO(2)) and 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF(6)]) along the saturated line of CO(2) at 40 degrees C up to 20.0 MPa. The sound velocity decreased more than 10% by increasing the pressure to 10 MPa, and the pressure effect was...
Abstract Background and aims:Nowadays, the non-thermal plasma is considered as a successful new technology with high efficiency in the air pollution control and is in the focal attention of the researchers. Various types of atmospheric pollutants adversely influence on the human health and the environment regionally and globally. Carbon monoxide has been introduced as a critical pollutant wh...
carbon monoxide (co) poisoning is still a health problem all over the world. informing users about symptoms and suggesting annual inspection of co producing devices will result in co poisoning reduction. the goal of this study was to evaluate awareness about co poisoning symptoms and its prevention ways in iranian population. in this study, a total of 700 patients' family members attended imam ...
The aim of the present study was to determine: 1) whether 40-50 ppm nitric oxide (NO) increases diffusing capacity of the lung for NO (D(L,NO)) and carbon monoxide (D(L,CO)), membrane diffusing capacity for CO (D(m,CO)) and pulmonary capillary blood volume (V(c)); 2) the actual number of tests required to provide a reasonable estimate of D(L,NO), D(L,CO), D(m,CO) and V(c); and 3) repeatability ...
BACKGROUND Analysis of volatile organic chemicals in breath holds promise for noninvasive diagnosis and monitoring of patients, but investigation of this in experimental mouse models has been limited. Of particular interest is endogenous production of carbon monoxide as a biomarker of inflammation and, more particularly, during sepsis. METHODS Using a nose-only collection procedure for unanes...
The study was done on how adsorption of carbon monoxide gas on the catalytic surface is affected by doping with boron and phosphorus in metallic nickel powder. The effect of doping was investigated using FTIR spectroscopy and compared to the spectra obtained from adsorption of carbon monoxide on pure nickel catalyst surface. An understanding of the results obtained from the nickel sample was al...
