Theoretical and field analyses indicate that longitudinal dispersivity is scale-dependent in porous media and that transverse dispersivity is generally one or more orders of magnitude smaller , causing solute plumes to be long and thin . Students learn the theoretical and practical elements of radio production and radio station operation . Following a general overview of the theoretical foundations and the exciting technological promises of nanophotonic materials , the tutorial will then focus on theoretical and experimental studies on the properties of a number of experimental structures that have captured a lot of recent attention , including in-plane photonic crystal integrated circuits , photonic bandgap fiber structures , and self-assembly approach to photonic crystal . The actual impact of any intentional epidemic was theoretical and would remain so . Graduates have the theoretical and practical knowledge needed for efficient and sustainable production of food , feed , and fiber .
