Seismic transmission tomography: determination of the elastic properties of building structures (some examples)
applied geophysics cultural heritage inversion seismic tomography
2015/9/29
This paper is a general review on seismic transmission tomography considering data acquisition and processing. Some questions on linear and non linear inversions are tackled, and advice given on the c...
Properties of the geoelectric structure that promote the detectionof electrotelluric anomalies:the case of Ioannina,Greece
Electrotelluric Greece magnetotelluric Mohr circle noise reduction seismic precursor tensor decomposition
2015/9/28
The reliable detection and identification of electrotelluric anomalies that could be considered as precursory phenomena of earthquakes become fundamental aspects of earthquake prediction research. Spe...
Statistical properties of the deviations of f 0 F 2 from monthly medians
deviations solar cycle
2015/9/25
The deviations of hourly f 0 F 2 from monthly medians for 20 stations in Europe during the period 1958-1998 are studied. Spectral analysis is used to show that, both for original data (for each hour) ...
Properties of the main trough of the F region derived from Dynamic Explorer 2 data
ionosphere on in-situ electron density
2015/9/25
In winter and equinoctial season nights, the main trough of the F region is an important stable structure of the ionosphere at the border between mid and high latitudes. Therefore it has to be taken i...
Acid-base properties and structons: towards a structural model for predicting the thermodynamic properties of silicate melts
silicate melt acid-base oxide melt thermodynamic properties
2015/9/10
Phase equilibrium relationships in igneous systems can be estimated using empirical mathematical models based on
multi-component regular solution formulae. Although these provide useable results with...
Accuracy in mineral identification: image spectral and spatial resolutions and mineral spectral properties
reflectance spectroscopy VIS-SWIR rock identification spectral resolution spatial resolution noise effects
2015/9/7
Problems related to airborne hyperspectral image data are reviewed and the requirements for data analysis applied to mineralogical (rocks and soils) interpretation are discussed. The variability of mi...

2015/1/6
Recently, the potential for biochar use to recapture excess nutrients from dairy wastewater has been a focus of a growing number of studies. It is suggested that biochar produced from locally availabl...
Furfural and its biochar improve the general properties of a saline soil
Organic materials saline soil the physical and chemical properties low fertility biochar
2015/1/6
Organic materials (e.g., furfural residue) are generally believed to improve the physical and chemical properties of saline soils with low fertility. Recently, biochar has been received more attention...
