For efficient mine planning and economic assessment, knowledge of subsurface structures ahead of mining in 3D and with high resolution is very useful. Tools such as 3D seismology have been adapted from the oil industry and applied to the planning of ultra-deep mines, but these tools lack the resolution to reveal <20 m features that hazard mine workings (Pretorious et al., 1997). Three-dimension...

Unilateral single ectopic ureters associated with contra lateral renal agenesia and hypoplastic bladder are rare and difficult to treat. Urinary diversion is usually performed because of small bladder capacity. We report a case treated by staged operation without urinary diversion or bladder augmentation.

Aim:To assess the skeletal and dental maturation of different facial types in growing children of south Indian population. Material and Methods: This study comprised of 60 samples with age group of 9-13 years and divided into 3 groups i.e Average growth pattern (control), Vertical growth pattern and Horizontal growth pattern . Lateral cephalograph , Hand wrist radiograph and Panoramic radiograp...

Shipboard acoustic Doppler current profiler and conductivity-temperaturedepth data obtained during highly stratified conditions in the Hudson River estuary along a section of variable width and breadth are presented. The observations emphasize tidal period asymmetries in the vertical structure of current and salinity. However, these asymmetries exhibit significant along-channel structure which ...

In this paper, we present two methods for determining the position of a leak in an open water channel. The available measurements are the water level and the gate position at the upstream and downstream end of a channel reach. We assume that the size of the leak and the time it started are already estimated by a leak-detection method. Both of the proposed methods make use of a nonlinear Saint-V...

Paediatric spinal deformities are the most prevalent musculoskeletal conditions observed in children and youth. Idiopathic Scoliosis (IS), a sub-class of these spinal deformities is commonly recognized by a lateral curvature of the spine that is of unknown cause and has the greatest risk of progression during periods of rapid growth and development.[1,2,3] The emergence of our contemporary pers...

Two methods for patterning surfaces with supported lipid bilayers and immobilized protein are described. First, proteins are used to fabricate corrals for supported lipid bilayers. Poly(dimethylsiloxane) stamps are used to deposit arbitrarily shaped patterns of thin layers of immobilized protein onto glass surfaces. This is followed by vesicle fusion into the regions that are not coated with pr...

In transversely isotropic media with a vertical axis of symmetry (VTI media), we represent the image in vertical time, as opposed to depth, thus eliminating the inherent ambiguity of resolving the vertical P-wave velocity from surface seismic data. In this new (x±t)-domain, the ray tracing and eikonal equations are completely independent of the vertical P-wave velocity, with the condition that ...

Most animal tissues and organ systems are comprised of highly ordered arrays of varying cell types. The development of external sensory organs requires complex cell-cell communication in order to give each cell a specific identity and to ensure a regular distributed pattern of the sensory bristles. This involves both long and short range signaling mediated by either diffusible or cell anchored ...

Amyotrophic lateral sclerosis (ALS) is a rapid neurodegenerative disease that affects the speech motor functions of patients, thus causes dysarthria. There is no definite marker for the diagnosis of ALS. Currently, the diagnosis of ALS is primarily based on clinical observations of upper and lower motor neuron damage in the absence of other causes, which is timeconsuming, of high cost, and ofte...
