Introduction.Cable structures belong to perspective roof systems.Specialized software packages for structural analysis, however, do not provide optimization tools for obtaining efficient design solutions of the cable structures.Thus, development of improved methods for design and analysis of cable systems is an important task to be solved.An advanc
In conventional concrete pavement design methods the design parameters are determined using linear elastic analysis.Concrete is subject to significant size effect and Ledges as a result linear elastic design concepts, such as the modulus of rupture determined for a beam, have limited reliability in the design of elements of different size and geome
The thermal conductivity of powdered media is characteristically very low in vacuum, and is effectively dependent on many parameters of their constituent particles and packing structure.Understanding of the heat transfer mechanism within powder layers in vacuum and theoretical modeling of their Digital Mixers thermal conductivity are of great impor
A 12-year-old boy presented with poor flow and recurrent urinary tract infections following hypospadias repair at the age of 3 years.The evaluation revealed urethral duplication with a hypoplastic dorsal urethra and patent ventral urethra.He also Wall Art had duplication of the bladder neck, and on voiding cystourethrogram Posture Board the ventral
