During the oxidation of silicon, interstitials are generated at the oxidizing surface and diffuse into the silicon. Boron diffusion was used to map the local interstitial super-saturation, the ratio of interstitial concentration to the equilibrium concentration of interstitials I/I, versus depth above buried Si0.795Ge0.2C0.005 layers during oxidation. The average interstitial supersaturation at...

A pilot carbon dioxide (CO2) sequestration experiment was carried out in the Michigan Basin in which 10,000 tonnes of supercritical CO2was injected into the Bass Island Dolomite (BILD) at 1050 mdepth. A passive seismic monitoring (PSM) network was operated before, during and after the 17-day injection period. The seismic monitoring network consisted of two arrays of eight, three-component senso...

OBJECTIVE To compare the effectiveness of repeated acupuncture stimulation and local anaesthetic injection at the most painful points in patients with low back pain. METHOD This randomised controlled clinical trial involved 26 patients with low back pain randomly allocated to either an acupuncture group (n = 13) or a local anaesthetic injection group (n = 13). Both acupuncture and anaesthetic...

the rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. also, co2 sequestration into the depleted reservoirs has attracted a large attention recently. however, it is important to ensure that the injection pressure is maintained below a certain limit to avoid unsealing the cap rock or reactivation of any...

The CSIRO In-Situ Laboratory Project (ISL) is located in Western Australia and has two main objectives related to monitoring leaks from a CO2 storage complex by controlled-release experiments: 1) improving the monitorability of gaseous accumulations at intermediate depth, 2) assessing impact faults on migration. A first test In-situ Lab evaluated ability monitor detect unwanted leakage major fa...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...

An experiment was conducted to evaluate the efficacy of intra-amnion administration of different doses of ascorbic acid (AA) on hatchability, growth performance, blood metabolites, jejunal morphology, and tibia breaking strength in 36h post hatch fasted broiler chickens. Two hundred eighty-eight Ross-308 fertile eggs at the 15thday of incubation were divided into four treatment groups, each con...

[1] The bubble cloud depth and its correlation with extreme winds are key elements of bubble‐mediated gas injection, which are critical to the determination of the global gas budgets. The characteristics of bubble cloud depth were examined frommeasurements collected during the passage of a category‐4 hurricane with winds up to 50 m s. The bubble cloud depth increases linearly with wind speed fo...
