In spinal cord injuries, direct trauma by edges of sublaxated or dislocated vertebrae and indirect ischemia as a result of vascular injury necrotize the neural tissue. After spinal cord injury, tissue loss appears as micro- or macrocavitation. Accumulations of non-neuronal cells substitute spared tissue and halts axon regrowth. Lack of supporting cells (secreting trophic factors and matrix) agg...

ABSTRACT: The 21 century is witnessing a rapid growth in the electrical energy demand due to rise in a large number of electrical gadgets. The conventional sources of energy, which are reliably supplying the energy, are rapidly depleting and the crisis is not near. Therefore, the lookout of non-conventional sources of energy is still on, particularly, the one which can perfectly replace these c...

Highly uniform step and termination structures on 4Hand 6H-SiC(0001) surfaces have been prepared via moderate annealing in disilane. Atomic force microscopy and dark-field low-energy electron microscopy imaging indicate single-phase terminations separated solely by half-unit-cell-height steps, driven by stacking fault energy. The atomic structure of 4H-SiC(0001)p 3 p3R30 -Si has been determined...

Earthquakes can cause tremendous loss of life and property yet predicting the behavior of earthquake fault systems is exceptionally difficult. The Earths crust is complex and earthquakes generate at depth, which is problematic for understanding earthquake fault behavior. Geodetic imaging observations of crustal deformation from Global Positioning System (GPS) and Interferometric Synthetic Apert...

Traditionally, a fault handling strategy is considered effective if it covers large classes of faults, e.g., all single faults. This conventional wisdom has recently been challenged by identifying subsets of faults which are acceptable at system level. One example is a fault in an imaging microchip which does not result in a deterioration of the calculated image to the extent that a human viewe...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

It is important to precisely know the whole time history of various types of fault slip events to understand the physics of earthquake generation. We develop a new time dependent inversion method for imaging transient fault slips from geodetic data. Past studies employed a linear Gaussian state space model and applied Kalman filter. The Kalman filter based methods, however, do not allow any var...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...
