Submarine channel–levee systems are among the largest sedimentary structures on the ocean floor. These channels have a sinuous pattern and are the main conduits for turbidity currents to transport sediment to the deep ocean. Recent observations have shown that their sinuosity decreases strongly with latitude, with high-latitude channels being much straighter than similar channels near the Equat...

We report the multiwavelength observations of one intermediate redshift (z=0.3884) galaxy in the Marano Field. These data include ISOCAM middle infrared, VLT/FORS2 spectroscopic and photometric data, associated with the ATCA 1.4 GHz radio and ROSAT PSPC X-ray observations from literature. The Spectral Energy Distribution obtained by VLT spectroscopy exhibits its early-type galaxy property, whil...

the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...

A field experiment in the waters off the south-eastern coast of Cyprus was carried out to study near-field formation of sediment plumes from dumping. Different loads of sediment were poured into calm and limpid waters one at the time from just above the sea surface. The associated plumes, gravitating towards the seafloor, were filmed simultaneously by four divers situated at different depths in...

maximum values occurring at mean moisture contents of 0.17 cm 3 /cm 3 and 0.19 cm 3 /cm 3 for the 800 m and 50-km scale, respectively. Based on these data, they derived empirical relationships between the coefficient of variation and the mean soil moisture content in order to estimate the uncertainty in field observations of mean moisture content. The authors are to be commended for providing t...

The rapid crossing of the solar equatorial region by Ulysses as it returned from the south pole resulted in 7 crossings of the heliospheric current sheet between 10“S and 20”N and 10 distinct solar wind interaction regions between 18“S and 22”N. Both the extent of the current sheet and the latitude interval containing the interaction regions are a f~ctor of= 2 less than were observed by Ulysses...

It has been well established in animal models that electrical fields generated during inter-ictal and ictal discharges are strong enough in intensity to influence action potential firing threshold and synchronization. We discuss recently published data from microelectrode array recordings of human neocortical seizures and speculate about the possible role of field effects in neuronal synchroniz...
