An optical study has been made of La0 ·7Ca0 ·3MnO3 and La0 ·8Li0 ·2MnO3 in the infrared spectral region (100 cm−1 to 4000 cm−1). The transmission of all samples is negligible. The photoconductive response is also unmeasurable. The data reported are therefore restricted to reflectivity measurements. At room temperature, both materials exhibit similar ‘bending’ and ‘stretching’ phonon modes, asso...

A survey is given of experimental studies of electron attachment and recombination in dense molecular media, from which information on the effect of van der Waals potentials or on the existence of surrounding molecules on these processes is obtained.

Accurate low-energy electron scattering data are needed in many fields of physics. However, accurate experiments are difficult to design and to carry out. By 1967 low-energy electron–He cross sections had been measured by two different techniques, designed to provide accurate data. Unfortunately, the data differed by amounts well outside the estimated error bars. Despite the relative simplicity...
متن کاملGPS Interference detected in Sydney-Australia
Radio frequency interference affects the integrity, continuity and availability of the GPS system. These are the highly important parameters for critical applications like aviation. Interference also has an adverse impact on accuracy. Continuously operating reference stations (CORS) networks are employed to improve the accuracy of GPS position measurements used by surveyors. Interference can af...

Importing key concepts from explanatory combinatorial lexicology, we revisit the notion of grammeme and show that it is an entity of the same level of abstraction as a vocable. Grammemes are polysemic and one of their acceptations is the basic one from which the others are derived. We propose criteria to identify it, and show how it can be used to guide the grouping of grammemes into inflection...
