The Aydintepe underground settlement in northeastern Turkey is a series of subsurface galleries carved in Eocene‐aged volcanic tuff. Rescue excavations conducted by the Local Archaeological Museum of Erzurum in 1996 and 1997 uncovered a large settlement with several underground rooms linked by passages. According to the excavators, it may have been built as a hideout and shelter by the first Christians who were banished by the Romans during the 3rd century A.D. Despite its historical and touristic value, parts of the underground settlement at Aydintepe have been destroyed to make room for the construction of new buildings in the modern town. As part of a conservation strategy for this important archaeological resource, a series of ground penetrating radar (GPR) and electrical resistivity measurements were conducted along eight profiles between 2003 and 2005. GPR soundings with a 100‐MHz unshielded antenna yielded reflected hyperbolic signals with high amplitude from tunnel structures. These highamplitude signals corresponded to areas of high electrical resistivity. These anomalies allow us to determine the probable locations of tunnels within the underground settlement and they provide important data that can be used to prevent future damage from modern construction. © 2008 Wiley Periodicals, Inc. 相似文献

An online survey about climate change was conducted 2008/2009 among all university members (N = 3541). Using the Theory of
Planned Behavior and Cultural Theory within a structural equation modeling approach, one main goal was to explain climate-friendly
behavioral intentions and the underlying psychological processes comprehensively and to show the interdependencies between
both approaches. The model explained 72% of the variance in Intentions to use public transport. Attitude towards public transport
(beta = 0.67, p < .001) most strongly influenced Intentions followed by Subjective Norms (beta = 0.23, p < .001). In turn,
Attitudes and Norm were explained by the value types Egalitarian, Individualist and Fatalist (24% and 14% respectively). These
value types are mediated through Attitudes and Subjective Norms. Recommendations regarding the support of climate friendly
behavior are formulated. 相似文献

The study area lies in the K??lada? province of western Turkey. The site has an approximate dimension of 1.5 to 2 km north‐south length and 3 km east‐west width. Combined methods from the fields of geology, geochemistry and geophysics were applied to elucidate the regional geologic framework and identify favorable environs for mineralization. There are a few volcanic hills in the center of the K??lada? caldera, which is actually a field of interest. Magnetics (M), Magnetic Total Field Gradient (Mg), Radiometry (Ra), Microgravity (MG) and Microgravity Gradient (MGG) methods were used to prospect the terrains and boundaries of gold and silver deposition in the area. The observed mineralized zones are characterized by low magnetization, low radiation, and high density contrast. Such zones appear to exist outside and beneath a magnetized cap rock. The locations of proposed drill holes were determined with varying depths. Following completion of geophysical and geochemical exploration, an open cut mine with a yearly production rate of about 5 to 6 tons of gold minerals at depths varying between 50 to 225 m has been operational. 相似文献

Most realistic Earth models published as yet have been given in tabulated form, with the noticeable exception of three simple
parametric Earth models derived by Dziewonski et al. (1975). Simple interpolation in these tables may lead to inconsistencies,
when we consider certain effects which depend crucially on detailed density structure. We establish algorithmic formulae,
which may be used to compute all the mechanical properties of a model in an entirely consistent way, once the density as well
asP— andS— wave velocities are known. We then use this formulation to integrate Clairaut’s equation in a very efficient way, and thus
obtain the hydrostatic flattening to the first order in smallness at any point inside the model. For most geodynamic purposes,
we may suffice with this approximation. Finally, we show the results of some calculations of hydrostatic flattening to the
first and second order, using an iterative technique of solving the integral figure equations, for an Earth model consistent
with all geophysical data available at present. We find that the hydrostatic flattening at the surface should be about 1/298.8,
instead of 1/296.961 as quoted by Nakiboglu (1979) for essentially the same model. Moreover, from our results, we estimate
the actual flattening of the coremantle boundary to be about 1/390.3. 相似文献

One of the possible magnetic field effects on the stellar pulsations is known to be a splitting in the observed frequencies. Using this knowledge in the solar convection zone, there are two aims in this work Considering the Sun as an incompressible fluid, our first objective was to investigate the variation of the physical parameters in the 30% outermost convective solar layer, during a pulsation period. The second purpose was to calculate, by means of the spherical harmonics, the shifts on the low-l p-mode frequencies which could be caused by the presence of the magnetic field in the Sun. The first order perturbation approximation was used in order to calculate analytically the resulting frequency shifts and the small perturbations on the magnetic field, as well as the physical parameters, such as density, pressure and temperature, of a Standard Solar Model excluding both rotation and magnetic field (Christensen-Dalsgaard et al., 1996) in the unperturbed equilibrium case. 相似文献
