A model of the electrical resistivity of Mt. Vesuvius has been elaborated to investigate the present structure of the volcanic edifice. The model is based on electrical conductivity measurements in the laboratory, on geophysical information, in particular, magnetotelluric (MT) data, and on petrological and geochemical constraints. Both 1-D and 3-D simulations explored the effect of depth, volum...

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...

Abstract This paper focuses on the thermal characteristic of torrefied pinecone pellets. The resistivity heating system was used for torrefaction purposes. conducted at 523 K different holding times 5, 10 and 15 minutes. behaviour pellet numerically predicted using pdepe algorithm. A parabolic 2-D heat transfer equation to estimate profile across pinecone. effect interactive atmosphere numerica...

Transparent conductive aluminum-doped ZnO (AZO) films were prepared by RF magnetron sputtering on glass substrates with specifically designed ZnO target using high-purity of zinc oxide (99.99%) and aluminum hydroxide (99.99%) powders. Systematic study on dependence of target-to-substrate distance (D ) on structural, electrical and optical properties of the as-grown AZO ts films was mainly inves...

Intracranial bleeding is one of the most severe medical emergencies in neurosurgery. Early detection or diagnosis would largely reduce the rate of disability and mortality, and improve the prognosis of the patients. Electrical Impedance Tomography (EIT) can non-invasively image the internal resistivity distribution within a human body using a ring of external electrodes, and is thus a promising...
