The effects of ultrasonic and thermo-chemical pre-treatments on the methane production potential of anaerobic co-digestion with synthetic kitchen waste (KW) or fat, oil and grease (FOG) were investigated. Non-linear regressions were fitted to accurately assess and compare the methane production from co-digestion under the various pre-treatment conditions and to achieve representative simulation...

Woven fabrics prove to be a very convenient fibre reinforcement when prepreg layers have to be draped on to double curvature moulds. The process of draping causes the angle between the warp and weft yarns to vary over the product with this double curvature. As a result, the thermomechanical properties of the fibre reinforced composite material show a corresponding distribution. These thermo-ela...

this paper dealswith thermo-mineral groundwater of themondragone plain (campania, southernitaly) and the possibility to use this low enthalpy geothermal resource. in the nw sector of this plain, at thebottom of mt. pizzuto, near the sea, there are thermo-mineral waters (50 °c) of sodium-chloride type,sulfureous and rich in co2 whose recharge is from the mt. pizzuto groundwater body. in the se s...

OBJECTIVES This study sought to validate a new method for direct volumetric blood flow measurement in coronary arteries in animals and in conscious humans during cardiac catheterization. BACKGROUND Direct volumetric measurement of blood flow in selective coronary arteries would be useful for studying the coronary circulation. METHODS Based on the principle of thermodilution with continuous ...

Different species and genotypes of Miscanthus were analysed to determine the influence of genotypic variation and harvest time on cell wall composition and the products which may be refined via pyrolysis. Wet chemical, thermo-gravimetric (TGA) and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) methods were used to identify the main pyrolysis products and determine the extent to which...

A layer of compressible, rotating, elastico-viscous fluid of related density heated & soluted from below is considered in the presence of vertical magnetic field to include the effect of Hall currents. Dispersion relation governing the effect of visco-elasticity, salinity gradient, rotation, magnetic field and Hall currents is derived. For the case of stationary convection, the Rivlin-Erickson ...
