Introduction: Mercury is one of the toxic metals that damages the nervous system and kidneys. Therefore, monitoring of mercury vapors in the environments is essential. .Material and Method: A new adsorbent was made from silver nanoparticles on a bed of quartz. The nano-adsorbent was capable for sampling of the trace amounts of mercury vapor from air. In this study, the required mercury vapor ...
[1] Floor-Fractured Craters (FFCs) are a class of lunar craters characterized by anomalously shallow floors cut by radial, concentric, and/or polygonal fractures; additional interior features are moats, ridges, and patches of mare material. Two formation mechanisms have been hypothesized—floor uplift in response to shallow magmatic intrusion and sill formation, and floor shallowing in response ...
A combination of classical thermodynamics and molecular theory was used to calculate the enhancement factor (ratio of vapor-phase partial pressure to saturated vapor pressure) for liquid mercury in equilibrium with air at standard atmospheric pressure at temperatures from 0 ◦C to 40 ◦C. The enhancement factors range from 1.0025 at 0 ◦C to 1.0016 at 40 ◦C. This enhancement is too small in magnit...
Pore and its structural characteristics are key parameters affecting shale gas reservoir development. Accurate quantitative characterization of pore is great significance for evaluating state. In this study, 15 shallow marine samples were collected in Well Y108. X-ray diffraction results indicate that brittle minerals the most common components shale. paper, various types classified characteriz...
Both the standard mercury sphygmomanometer and the random-zero sphygmomanometer have been used in epidemiological studies and clinical trials. Problems arise in comparing studies since, in addition to other methodological differences, the readings obtained with the random-zero sphygmomanometer have been found to be lower than those obtained with the standard mercury sphygmomanometer. In the pre...
This article reports the findings of a small evaluation audit which compares the Dyna-Form Mercury Advance Mattress to that of the Softform Premier Active Mattress (a foam mattress with dynamic underlay). A small group of patients with similar co-morbidities who were an emergency admission were recruited to an evaluation audit. Their median age and Waterlow score indicated that these patients w...
