In recent years, the dirt pick up problem and loss quality of brightness of traffic marking paints have widely attracted municipal authorities’ attention. Reflective traffic paints and road marking are some of the most technologically advanced pieces of safety and traffic signs that should be there to have safe streets [1-5]. The most important problem regarding with today’s traffic marking pai...
We present models for the structure of the crust and upper mantle beneath lunar impact basins from an inversion of gravity and topographic data from the nearside of the moon. All basin models display a thinner crust and an elevated Moho beneath the central basin region compared to surrounding areas, a signature of the processes of basin excavation and mantle uplift during collapse of the transi...

Coal based thermal power generation accounts for 44.7% of the world's electricity and coal alone provides about 80% of the total energy demand in India. Energy-intensive industries deteriorate the air quality of the residential areas due to release of different pollutants, especially a range of deleterious heavy metals like Hg, Cd, Cu, Pb, and Cr. Near about 53.3 percent of the coal produced ev...
The quantum phenomena of spectral flow which has been observed in laboratory superfluids, such as He-B, controls the drift velocity of proton type II superconductor vortices in the liquid core of a neutron star and so determines the rate at which magnetic flux can be expelled from the core to the crust. In the earliest and most active phases of the anomalous X-ray pulsars and soft-gamma repeate...
We investigate the role of neutron star superfluidity for magnetar oscillations. Using a plane-wave analysis we estimate the effects of a neutron superfluid in the elastic crust region. We demonstrate that the superfluid imprint is likely to be more significant than the effects of the crustal magnetic field. We also consider the region immediately beneath the crust, where superfluid neutrons ar...
The magnitude of crustal extension across the northern Basin and Range province is a matter of longstanding controversy; estimates range from 10 to 3009~,. Recently published estimates of extension across the southern Basin and Range province (36°N) are in the range of 80-100%. Thus, the larger values suggested for the northern part of the province (40°N) seem to require substantial countercloc...
This thesis consists of three papers examining problems related to the crustal structure, isostasy and subsidence history of aseismic ridges and mid-plate island chains. Analysis of gravity and bathymetry data across the Ninetyeast and eastern Walvis Ridges indicates these features are locally compensated by an overthickening of the oceanic crust. Maximum crustal thicknesses are 15-30 km. The w...
