This paper presents a personal account of developments in the solution two related problems that limited accuracy ionosphere calculations 1980s. The first problem concerns model-data discrepancies photoelectron flux spectrum. Early comparisons between measured and modeled data revealed magnitude shape. A lateral thinking approach there were with key model inputs: namely, electron impact cross-s...

in the realistic manner, piles are similar to the slender columns that soil around them acts as a lateral support. the piles situated in the liquefiable soil layers, loss their lateral supports due to the liquefaction resulted from the seismic ground motion. in this case, pile has the potency of axial instability similar to the unsupported columns. this instability can lead to the lateral buckl...

background: supracondylar fracture of the humerus is the second most common fracture in children. for most cases closed reduction and percutaneous crossed pinning is recommended. those patients who had previously undergone an unsuccessful closed reduction trial need open reduction and pin fixation, but the best surgical approach is questionable. most surgeons apply the technique of posterior or...
