Recently others advocated frequent radiological surveillance to detect upper urinary tract deterioration in children with neurogenic bladder secondary spina bifida. We reviewed the consequences of such expectant management on compliance and continence.We retrospectively records 214 presenting our bifida clinic a 13-year period. Follow-up is available for 95 girls 86 boys. Imaging studies kidneys were repeated at 6 12-month intervals. Urodynamics performed when tracts deteriorated or...

The structure of a new mineral jadarite, LiNaSiB 3 O 7 (OH) (IMA 2006–36), has been determined by simulated annealing and Rietveld refinement laboratory X-ray powder diffraction data. contains layer corner-sharing, tetrahedrally coordinated Li, Si B forming an unbranched vierer single layer, which is decorated with triangular BO groups. Na ion situated between the tetrahedral layers in distorted octahedral site. As very high boron content this makes obtaining neutron data problematic, ab...

Abstract High-resolution acoustic imaging technology has been developed and deployed to map the downhole location orientation of fiber optic lines in unconventional oil gas carbon capture wells. Fiber installations are long term monitoring solutions providing continuous measurement temperature, sound, or strain. These provide significant insight into operation optimization assets but require a large capital investment, typically upwards million dollars. By accurately mapping lines, operators...
