Electrolytic desaturation is a potential method for improving the liquefaction resistance of liquefiable foundations by reducing soil saturation. In this study, in situ tests were performed to investigate resistivity at different depth and water level foundation under currents. The test results show that constant currents 1, 2, 3 A (ampere, unit direct current), saturation treated reached 87%, ...

Denitrification may represent an important mechanism in the fate of N applied to turf. Denitrification losses were directly measured from fertilized 'Baron' Kentucky bluegrass (Poa pratensis L.) sod samples sealed in acrylic chambers using the acetylene inhibition technique. Losses were correlated with soil texture, percent soil sat· uration (SAT), and temperature. Losses from turf on a Hadley ...

Natural gas hydrate (NGH) concentrations hold large reserves of relatively pure unconventional natural gases, consisting mainly of methane. Depressurization is emerging as the optimum conversion technology for converting NGH in its reservoir to its constituent water and natural gas. NGH concentrations commonly have a pore fill of over 80%, which means that NGH is a low-permeability reservoir, a...

Mechanisms for interpreting anomalous decreases in radon in ground water prior to earthquakes are examined with the help of a case study to show that radon potentially is a sensitive tracer of strain changes in the crust preceding an earthquake. The 2003 Chengkung earthquake of magnitude (M) 6.8 on December 10, 2003, was the strongest earthquake near the Chengkung area in eastern Taiwan since 1...

AT THE present time the most widely used method of studying the effect of induced anoxemia on the cardiovascular system consists of giving the subjects low oxygen gas (usually 10 per cent) inhalation for approximately twenty minutes and making observations during this period. In previous communications1'the variability of the degree of anoxemia, as measured by the blood arterial oxygen saturati...

S U M M A R Y Using a numerical approach, we explore wave-induced fluid flow effects in partially saturated porous rocks in which the gas–water saturation patterns are governed by mesoscopic heterogeneities associated with the dry frame properties. The link between the dry frame properties and the gas saturation is defined by the assumption of capillary pressure equilibrium, which in the presen...

OBJECTIVE: Demonstrate the effectiveness and the good outcome of the patients treated with helium-oxygen (Heliox) mixture. This mixture (Heliox) has been used in patients with airway obstruction, from different ethiologies, who did not respond to a conventional treatment with oxygen. METHODS: Case report of five patients that received Heliox as treatment for airway obstruction. All of them had ...
