In accordance with an old suggestion of Asher Peres (1962), we consider theelectromagnetic field as fundamental and the metric as a subsidiary field. Infollowing up this thought, we formulate Maxwell's theory in a diffeomorphisminvariant and metric-independent way. The electromagnetic field is then...

The first rule in optimizing such a layout is to isolate the converter. DC-DC converters are an excellent source of electric and magnetic fields. Their EMI spectrum begins at the switching frequency and often extends over 100MHz. To minimize capacitive couplings and "magnetic-field-to-loop" cou...
16, 96 For example, activity in the ventral mPFC is altered (reduced) when anxiety is transiently induced in healthy participants, by means of anticipation of pain.105 Similarly, activation of the insula cortex is altered by anxiety, with the idea being that those prone to anxiety have an ...
Since these fields have a capability of inducing much greater currents in an exposed user of the device than the relatively low magnetic field emissions, it certainly is desirable to shield the cover of the VDT. Since such shield- ing is relatively inexpensive the benefit to cost ratio is ...

This delay was maintained in the constant routine following cessation of the shift condi- tions demonstrating that endogenous metabolite rhythms can be induced and driven by external behavioural cues which likely reflect peripheral oscillators dissociating from that of the SCN, as concluded by the ...
