The Phase Problem of X-ray Crystallographye” ℒH, unobtainable from the diffraction experiment, must be assigned to each |JEH /< and the problem of determining the phases when only the magnitudes E. are known is called the “phase problem”. Owing to the known atomicity of crystal structures and the redundancy of observed magnitudes E. |, the phase problem is solvable in principle.

Structural Obstacles Slow Business Lendingrticular the introduction of a bioamplification step in biosensors permits to push down the detection limits of these devices by one or more orders of magnitude and therefore to measure very low concentrations of analytes. In this way the concentration and purification steps, often required by other
