Armature Reaction
Armature Reaction: The effect of magnetic field set up by armature current on the distribution of flux under main poles of a generator. The armature magnetic field has two effects: (i) It demagnetises or weakens the main flux and (ii) It cross-magnetises or distorts it. Fig 1 shows the flux distribution of a bipolar generator when there is no current in the armature conductors. The brushes are ...
متن کاملCompounding for Iontophoresis
PREFACE Iontophoresis is a process which involves increased transport of solute molecules into a tissue using an electric current. This technique has been employed for the delivery of ionic drugs for local and systemic therapeutic effects in clinical settings. Iontophoresis is becoming more widespread today with many pharmacists compounding solutions for this mode of administration. Iontophores...

متن کاملPharmacy Compounding Primer for Physicians
Since the development of federal standards for drug approval, the practice of medicine has historically involved the compounding of medications based on a physician's determination that a US FDA-approved product either did not exist, or could not be used for medical reasons. Today, prescriptions for non-FDA-approved compounded drugs may be driven by fanciful and largely unregulated pharmacy adv...
متن کاملPlanetary Dynamos
The theory of planetary dynamos and its applications to observed phenomena of planetary magnetism are outlined. It is generally accepted that convection flows driven by thermal or compositional buoyancy are the most likely source for the sustenance of global planetary magnetic fields. While the existence of dynamos in electrically conducting fluid planetary cores provides constraints on propert...
