We compute crustal thickness in Epirus (NE Greece), from spectral analysis of the Bouguer gravity field.Moho depths were established from the slope of the log-power radial spectrum at the lower end of the wavenumber band and were found to vary from 31 to 38 km. This is in agreement with the results obtained by other investigators employing seismological methods of analysis.

The assessment of cultural heritage requires high-resolution and non-destructive methodologies. Ground-penetrating radar is widely applied in the inspection of historical buildings. However, some structures with curved surfaces make the radar data acquisition process difficult and consequently the following data interpretation. This paper describes a case study concerning a circular and buried Greek monument. This monument is a magnificent tomb buried with irregular stones. However, its structure and the internal stones arrangement are unknown. Therefore, a radar survey was carried out to achieve two main objectives: (i) identification of hidden elements and arrangement of the stones and (ii) detection of specific zones where further restoration and maintenance should be recommended. The methodology for the radar data acquisition involves the use of a laser scan in order to define accurately each radar line, covering all the internal surface of the tomb. Radar data processing was developed by converting Cartesian coordinates into polar coordinates. This procedure allows defining better the internal anomalies, improving the radar data interpretation. The main results of the survey were three: (i) the presence of a hidden target buried in the corridor access to the tomb; (ii) the description of the internal structure of the walls of the tomb, defining the stones arrangement and the position and depth to the keystone; and (iii) the existence of delimited zones where the signal is highly attenuated, probably due to a high salt content.internal damage, is also decisive in restoration and conservation processes. The inner information is usually gathered by means of non-destructive surveys in many cases.Ground-penetrating radar (GPR) is a non-destructive geophysical surveying technique that is nowadays applied to structures assessment. The methodology lays in the emission of highfrequency electromagnetic pulses that travel trough the medium. The changes in the electromagnetic properties of the medium are discontinuities, which are identified by the reflection of the energy. As a consequence, the technique provides images where the depth to the discontinuity is determined by the two-way travel time of the reflected waves on the A-scans. The projection on the surface is defined by the coordinates of the position of the receiver antenna in the B-scans. The knowledge of the depth and position of buried targets is fundamental in archaeological applications. Hence, the method has been widely used in this field during the last decades (Neubauer et al.

stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?
