in the present study, the capability of dried indigenous biomass of vibrio and oceanimonas, was assessed and compared for mercury biosorption from aqueous solutions. it was found that both of the biosorbents reached equilibrium after 60 min of contact although the mercury sorption capacity of vibrio was significantly more. its sorption capacity increased from 9 to 83 mg/g biomass by increasing ...

Despite the increasing popularity of blood pressure (BP) wrist monitors for self-BP measurement at home, device validation and the effect of arm position remains an issue. This study focused on the validation of the Omron HEM-609 wrist BP device, including an evaluation of the impact of arm position and pulse pressure on BP measurement validation. Fifty patients at high risk for cardiovascular ...

As an important component of coal structure, the macropores have a great influence on CBM recovery. In this paper, characteristic two samples collected from 3# seam in south Qinshui Basin, China was analyzed basic mercury intrusion porosimetry, and fully coupled triple-porosity/double permeability mathematical model for recovery established according to physical structure non-Darcy flow methane...

We investigate how light samples disordered porous materials such as ceramics and pharmaceutical materials. By combining photon time-of-flight spectroscopy and sensitive laser-based gas sensing, we obtain information on the extent to which light interacts with solid and pore volumes, respectively. Comparison with mercury intrusion porosimetry shows that light predominantly interacts with the so...

Many older homes are equipped with mercury-containing gas regulators that reduce the pressure of natural gas in the mains to the low pressure used in home gas piping. Removal of these regulators can result in elemental mercury spills inside the home. In the summer of 2000, mercury spills were discovered in the basements of several Chicago-area homes after removal of gas regulators by gas compan...

objective mercury poisoning is one of the important recent causes of mortality and mortality in children worldwide, particularly in industrial environments; mercury is a poisonous metal, especially harmful to the nervous and immune systems and the kidneys and can even be fatal. elemental mercury is present in thermometers, barometer batteries, sphygmomanometers and latex paints. inorganic mercu...

A muon collider or a neutrino factory based on a muon storage ring require intense beams of muons that can be generated by a 1-4 MW proton beam incident on a moving target inside a 20-T solenoid magnet, with a mercury jet as a preferred example. This paper addresses the thermodynamic interaction of the intense proton beam with the proposed mercury jet target, and the consequences of the generat...

Alkali activated binders are a new class of binding material with comparable or enhanced performance to Portland cement. These binding materials are obtained by a chemical reaction between an alumino-silicate material and a highly alkaline solution. In most cases, the setting-hardening process of this binder is performed at high curing temperatures. In this paper, alkali activated mortars based...

In the course of experiments' on the combination of hydrogen and oxygen in the presence of mercury vapor activated by absorption of the resonance radiation X 2537 A, it was found that the irradiation of oxygen alone in presence of mercury produced a small but still noticeable decrease of pressure. This effect might be due to ozone formation and subsequent oxidation of mercury, or to some other ...
