Radio direction finding

Navigation. Navigation encompasses a number of radio applications including radio direction finding (RDF), radar, loran, and Global Positioning System (GPS). 

A thin wire bent into a closed contour is called a loop antenna. The terminals of a loop antenna are formed by a small discontinuity or gap in the conducting wire. Loops have been used in such diverse applications as radio receiving antennas, direction finding, magnetic field-strength probes, as well as array elements. 

The residue levels of PBO and HMDS for the assayed commodities are presented in Table 10.3. The results show that the highest residues of both PBO and HMDS were found on leafy crops (e.g. lettuce, mustard greens, etc.) which are directly exposed to the spray. Lower residues are found on fruits and less exposed stems (e.g. broccoli) and minimal residues are found in commodities which are not directly exposed (e.g. potato tubers). Little or no translocation of PBO or closely related metabolites occurred. Low residue levels of HMDS-producing metabolites were found away from tbe application site. The results confirm the findings of the radio label led metabolism studies. 

Germanium is less common than carbon or silicon and less well known than tin or lead. Yet it is used extensively in all fiber optics, and it is used in some semiconductors too. It used to play a major part in the electronics industry as a rectifier because it could transmit electricity in one direction but not in the reverse direction. It was the element that was first used to make a transistor and was used in the first commercial transistor radios. But today it is less common to find it because it has been replaced by the cheap and prevalent silicon. It s still used in specialty devices such as wide-angle camera lenses, detectors, and some alloys. 

Woolf s social critique of the media comes from the pen of one who writes an alternative discourse and finds that discourse itself to be suppressed. Sometimes her protest was directed against legislated censorship at the institutional level she appeared, for example, as a witness (only to be dismissed) at the Radcliffe Hall trial for obscenity in 1928, and added her signature to a 1931 letter to The Times protesting against radio censorship on the occasion of the enforced expurgation of mention of Ulysses or Lady Chatterley s Lover in a talk by Harold Nicolson on the At other...
