the other hand he found that villages along the ghats* cutting the face of the plateau escarpment were intensely infected and he ll?ted that two particular villages, Angarah Bundkhela, situated at the top of the ghats otherwise apparently quite similar to filftges on the plateau were as highly infected any he had found at the foot of the scarp, ' nrr-^ley are notoriously malarious. His findings...

We determined radiogenic and cosmogenic noble gases in a mudstone on the floor of Gale Crater. A K-Ar age of 4.21 ± 0.35 billion years represents a mixture of detrital and authigenic components and confirms the expected antiquity of rocks comprising the crater rim. Cosmic-ray-produced (3)He, (21)Ne, and (36)Ar yield concordant surface exposure ages of 78 ± 30 million years. Surface exposure occ...

The electric arc furnace (EAF) is used to produce high quality steel from steel scraps. The EAF uses plasma arc to generate heat for melting scarp or direct reduced iron (DRI). The liquid metal should be drained from the tap hole. Manual tapping operation of the EAF in the hot environment around the furnace is a potentially dangerous and time consuming task for the workers. Therefore, it is ess...

SUMMARY During earthquakes, structural damage is often related to soil conditions. Following the 2014 April 1 Mw 8.1 Iquique earthquake in Northern Chile, infrastructure was reported cities of and Alto Hospicio. In this study, we investigate causes site amplification region by numerically analysing effects topography basins on observed waveforms frequency range 0.1–3.5 Hz using spectral element...

Elevations measured by the Mars Orbiter Laser Altimeter have yielded a high-accuracy global map of the topography of Mars. Dominant features include the low northern hemisphere, the Tharsis province, and the Hellas impact basin. The northern hemisphere depression is primarily a long-wavelength effect that has been shaped by an internal mechanism. The topography of Tharsis consists of two broad ...

The goal of this study was to characterize the eruptive behavior of Olympus Mons, Mars, by estimating flow speeds and volume fluxes for lava flows produced from various vents on the volcano. During my fellowship, I have made width, depth and ground slope measurements of 65 lava tubes and 271 channels from 56 MOC images and 65 THEMIS images of Olympus Mons. The data show that channels are more n...

From photogrammetric analysis of stereo images of Mercury obtained during three MESSENGER flybys, we have produced three digital terrain models (DTMs) that have a grid spacing of 1 km and together cover 30% of the planet’s surface. The terrain models provide a rich source of information on the morphology of Mercury’s surface, including details of tectonic scarp systems as well as impact craters...
