The Nernst Lamp ELECTRICAL CONDUCTIVITY IN NON-METALLIC MATERIALS
The use of carbon and tungsten filaments mounted in vacuum as early incandescent lamps is well-known, but it is less often realised that an early competitor was Nernst’s ceramic lamp. This made use of the property that , although good insulators at room temperature, many oxides become partially conductive when strongly heated. This is due to the migration of ions rather than electrons, and was ...
متن کاملThe fundus slit lamp
Fundus biomicroscopy with the slit lamp as it is practiced widely nowadays was not established until the 1980-es with the introduction of the Volk lenses +90 and +60D. Thereafter little progress has been made in retinal imaging with the slit lamp. It is the aim of this paper to fully exploit the potential of a video slit lamp for fundus documentation by using easily accessible additions. Suitab...
متن کاملWood lamp examination.
Pigment disorders1,3 Hypopigmentation or depigmentation. Lesions demonstrate increased sharpness of borders under Wood lamp examination and fluoresce bright blue-white owing to the increased amount of dermal collagen illuminated. This results from decreased or absent intervening melanin. Vitiligo: patches, varying in location and extent. Tuberous sclerosis: patches; characteristic shapes are la...
متن کامل" Thomson's Lamp Is Dysfunctional
James Thomson envisaged a lamp which would be turned on for 1 minute, off for 1/2 minute, on for 1/4 minute, etc. ad infinitum. He asked whether the lamp would be on or off at the end of 2 minutes. Use of “internal set theory” (a version of nonstandard analysis), developed by Edward Nelson, shows Thomson’s lamp is chimerical; its copy within set theory yields a contradiction. The demonstration ...
متن کاملThe lysosomal polypeptide transporter TAPL is stabilized by interaction with LAMP-1 and LAMP-2.
TAPL (ABCB9) is a homodimeric polypeptide translocation machinery which transports cytosolic peptides into the lumen of lysosomes for degradation. Since the function of proteins is strongly dependent on the interaction network involved, we investigated the interactome of TAPL. A proteomic approach allowed identification of the lysosome-associated membrane proteins LAMP-1 and LAMP-2B as the most...
