lse modes have an electric field that is zero in one transverse direction, and lsm modes have a magnetic field that is zero in one transverse direction. lse and lsm modes can occur in planar transmission line types with non-homogeneous transmission media. structures that are unable to support a pure te or tm mode, if they are able to support .
magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields.
in situ leaching or in situ recovery refers to the mining technique of injecting water underground to dissolve ore and bringing the uranium-impregnated water to the surface for extraction. petroleum production. in situ refers to recovery techniques which apply heat or solvents to heavy crude oil or bitumen reservoirs beneath the earth's crust.
for instance, recently we tried using a magnetic separator to remove the iron before the smelting process, which reduced the amount of iron ore that is processed, thereby improving the cost .
easily scaled up – the hydrodynamic conditions for particle collection inside the downcomer and separation in the tank are identical between the laboratory, pilot plant and industrial-scale jameson cell, meaning that there is direct scale-up. this makes predicting plant performance for small-scale tests strhtforward.
higher performance in hard disk drives comes from devices which have better performance characteristics. these performance characteristics can be grouped into two categories: access time and data transfer time or rate . the access time or response time of a rotating drive is a measure of the time it takes before the drive can actually transfer .
the insolubility of certain sodium minerals such as cryolite and feldspar arises from their polymeric anions, which in the case of feldspar is a polysilicate. astronomical observations. atomic sodium has a very strong spectral line in the yellow-orange part of the spectrum the same line as is used in sodium vapour street lights .
model predictive control mpc is an advanced method of process control that is used to control a process while satisfying a set of constraints. it has been in use in the process industries in chemical plants and oil refineries since the 1980s. in recent years it has also been used in power system balancing models and in power electronics.model predictive controllers rely on dynamic models of .
