This paper addresses the thermodynamic interaction of an intense proton beam with the proposed mercury jet target at a neutrino factory or muon collider source, and the consequences of the generated pressure waves on the target integrity. Specifically, a 24 GeV proton beam with approximately 1.6e13 protons per pulse and a pulse length of 2 nanosec will interact with a 1 cm diameter mercury jet ...

BACKGROUND Mercury is a contaminant that reaches high levels in Nunavik (North of Quebec). It is transformed into methylmercury (MeHg) and accumulated in marine mammals and predator fish, an important part of the traditional Inuit diet. MeHg has been suggested to affect BP in adults and children while the influence on HRV has only been studied in children. We aimed to assess the impact of MeHg ...

BACKGROUND Auscultatory mercury sphygmomanometers to measure blood pressure (BP) have been banned from health services because of risk of pollution and environmental accidents with mercury. Aneroid appliances could be an alternative. OBJECTIVE To validate the Missouri aneroid device for blood pressure measurement in cancer patients according to the protocol of the European Society of Hyperten...

In recent years, granular bentonite GB has become a reference material since it facilitates the backfilling operation due to high-density compacted granules with extended grain size distribution(maximum sizes around 10 mm). This investigation explores initial microstructure of MX80-type and hydro-mechanical HM response observed at phenomenological scale. Samples were statically fixed dry densit...

A number of wells in the Sichuan Basin China have tested industrial gas flow pressure arising from shale Da’anzhai section Ziliujing Formation, revealing good exploration potential. Microfractures shales affect enrichment and preservation are important storage spaces seepage channels for gas. In order to increase productivity reduce risks associated with exploration, types, connectivity, propor...

Porous alumina ceramics with different porosities were prepared via atmospheric pressure sintering using a sacrificial template method powder as the raw material and carbon fiber (CF) graphite pore-forming agents. The effects of contents ratios agents aspect CF on microstructure, mechanical properties, pore size, pore-size distribution porous samples investigated. In addition, surface fractal d...

method previously employed by westoo for the determination of alkylmercury compounds was producing very wide picks during g.c. analyses. changing the column temperature, carrier gas flow and pressure did not supersede the problem. therefore change in packing materials was experienced. 5% dc-200 on gas-chrom did not work. a packing material used for chlorinated hydrocarbons w, 80-100 mesh. as th...

We present a unified thermodynamic description of the breathing transitions between large pore (lp) and narrow pore (np) phases of MIL-53 (Cr) observed during the adsorption of guest molecules and the mechanical compression in the process of mercury porosimetry. By revisiting recent experimental data on mercury intrusion and in situ XRD during CO(2) adsorption, we demonstrate that the magnitude...

We demonstrate reversible wetting and filling of open single-wall carbon nanotubes with mercury by means of electrocapillary pressure originating from the application of a potential across an individual nanotube in contact with a mercury drop. Wetting improves the conductance in both metallic and semiconducting nanotube probes by decreasing contact resistance and forming a mercury nanowire insi...
