Space technology transfer policies: Learning from scientific satellite case studies

The paper reports research into the transfer of technology typically used in the construction of scientific satellites. Four case studies are analyzed to clarify some basic mechanisms of the transfer of space technology to the industrial system. The paper finds that the technologies analyzed in the construction of satellites for the most part stem from the integration of technical processes already known in various industrial sectors; the use of these processes in space involves their substantial strengthening and upgrading in terms of performance; and this upgrading permits them to return to industrial sectors that use the technological advances acquired for coping with complex problems in the space sector. This research has helped validate some of the determinants of technology transfer already noted in the literature, while increasing the number and content of these. Useful indications emerge for policy makers and agents involved in technology transfer programs.     

Survival of Deinococcus radiodurans against laboratory-simulated solar wind charged particles

In this experimental study, cells of the radiation-resistant bacterium Deinococcus radiodurans were exposed to several different sources of radiation chosen to replicate the charged particles found in the solar wind. Naked cells or cells mixed with dust grains (basalt or sandstone) differing in elemental composition were exposed to electrons, protons, and ions to determine the probability of cell survival after irradiation. Doses necessary to reduce the viability of cell population to 10% (LD(10)) were determined under different experimental conditions. The results of this study indicate that low-energy particle radiation (2-4?keV), typically present in the slow component of the solar wind, had no effect on dehydrated cells, even if exposed at fluences only reached in more than 1000 years at Sun-Earth distance (1 AU). Higher-energy ions (200?keV) found in solar flares would inactivate 90% of exposed cells after several events in less than 1 year at 1 AU. When mixed with dust grains, LD(10) increases about 10-fold. These results show that, compared to the highly deleterious effects of UV radiation, solar wind charged particles are relatively benign, and organisms protected under grains from UV radiation would also be protected from the charged particles considered in this study.     

A systematic review of the Space technology transfer literature: Research synthesis and emerging gaps

In order to justify high expenditure during this period of financial crisis, Space Agencies have attempted to increase the returns on their investments in Space missions by encouraging the commercial use of advanced technologies. The development of a technology transfer process from Space to Earth not only benefits the Aerospace industry but also the network of national companies. Technology transfer has been shown to stimulate innovation in business and commerce, support economic growth and provide a return on public investment in research and development (R&D). The aim of this paper is to systematically review the Space technology transfer literature and to suggest directions for future research. The range of research and studies in the literature on this topic requires a systematic review to summarize the results in an unbiased and balanced manner and to interpret these in a way that highlights the research gaps. This article presents an overview of the dominant thinking (explicit in selected articles from 1995 to present), indicating the problems of analysis, research gaps and a future research program.     

The Influence of Geometrical and Nongeometrical Features on the Use of the Lexical Concepts NEAR and FAR in English and Finnish

Abstract

This paper investigates the impact of geometrical and nongeometrical features on the use of the lexical concepts NEAR and FAR in English and Finnish. Participants' acceptability ratings for these concepts demonstrate that a bar in between a Figure and a Ground acts as a scale-setting object but not as a distance enhancing barrier, shows that the influence of the geometrical feature Figure–Ground distance exceeds the influence of several nongeometrical features, but most of all reveals that language specific lexical properties associated with NEAR and FAR predict language dependent effects for functional relatedness in interaction with Figure–Ground distance and bar presence.
