a multi-factor, multi-good, multi-country framework. Contrasting with previous studies, these models allow for cross-country differences in technology and factor prices, and for departures from some of the assumptions of the original HO theory, such as increasing returns and product differentiation

The interaction of X-rays or keV electrons with atmospheric neutrals may produce core-ionized species, which may decay by the production of characteristic X-rays or Auger

Heiko G. Niessen,Klaus Woelkness Media B. V. 2008 Keywords Aeronomy The term “aeronomy” has been used widely for many decades, but its origin has mostly been lost over the years. It was introduced by Sydney Chapman in a Letter to the Editor, entitled “Some Thoughts on Nomenclature”, in Nature in 1946 (Chapman 1946). In that le

l renders the assumptions of the models slightly more realistic, while the standard model is more general. The presence of product differentiation and economies of scale internal to the firm allows us to write separate factor content equations for exports and imports of the differentiated products.

The spectroscopic analysis of auroral emissions is discussed here, along with its relevance to precipitating particle diagnostics. Atmospheres can also be modified by the ene
