This paper presents the results of a two-year field campaign to determine the spatial and temporal variability of groundwater interaction with surface waters in two Cretaceous Chalk catchments (the Pang and Lambourn) in the Upper Thames in Berkshire, UK, based on measurement of dissolved carbon dioxide (CO 2). Average stream water concentrations of dissolved CO 2 were up to 35 times the concent...

Serious delayed encephalopathy and cognitive sequelae following acute carbon monoxide intoxication constitutes a rare and a distinct entity. A case of delayed encephalopathy and cognitive sequelae after acute carbon monoxide poisoning is presented. The patient is a 50-year-old Thai female with a history of carbon monoxide poisoning during her vacation tour in Arizona in winter. She developed en...

We report on the development of a continuous flow process for the palladium catalysed methoxycarbonylation of aryl, heteroaromatic and vinyl iodides and an aryl bromide using a Teflon AF-2400 based Tube-in-Tube reactor to mediate the selective permeation of carbon monoxide into solution at elevated pressures. The low volume of pressurised gas within the reactor (5.6 mL) offers the potential for...

CASE REPORT In this paper, two possible cases of acute carbon monoxide poisoning previously not identified in the medical and historical literature are discussed. The first concerns the famous Byzantine Emperor Julian the Apostate, who may have suffered mild carbon monoxide poisoning from which he quickly and completely recovered. The second case involves his successor, Jovian, who may have suc...

One distinct concentration of copper ions was embedded into the silica matrix to xerogel form using copper source Cu(NO3)2∙3H2O. The xerogel samples were prepared with using hydrolysis and condensation reactions of TetraEthyl Ortho-Silicate (TEOS) by the sol-gel method. In this investigation, new molar ratio of H2</su...

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...

Ordered nanoporous silicas containing various binary copper-manganese oxides were prepared as catalytic systems for effective carbon monoxide elimination. The carbon monoxide elimination efficiency was demonstrated as a function of the [Mn]/[Cu] ratio and reaction time. The prepared catalysts were characterized by Brunauer-Emmett-Teller (BET) method, small- and wide-angle X-ray diffraction (XRD...

background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...

Single-breath diffusing capacity of the lung for carbon monoxide (D(LCO)) is a common pulmonary function test that measures the ability of the lung to exchange gas across the alveolar-capillary interface. D(LCO) testing is used to narrow the differential diagnosis of obstructive and restrictive lung disease, to aid in disability and transplant assessment, and to monitor medication toxicity. Th...

The impact of the East Asian monsoon (EAM) on climatology and interannual variability of tropospheric ozone (O3) over the coastal South China was investigated by analyzing 11 years of ozonesonde data over Hong Kong with the aid of Lagrangian dispersion modeling of carbon monoxide and calculation of an EAM index. It was found that the seasonal cycle of O3 in the lower troposphere is highly relat...
