recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. at the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver int...

This paper develops a model that endogenizes both directed technologies and demography. Potential innovators decide which technologies to develop after considering available factors of production, and individuals decide the quality and quantity of their children after considering available technologies. This interaction allows us to evaluate potentially divergent development paths. We find that...

The paper provides a review of adaptive and intelligent technologies in a context of Web-based distance education. We analyze what kind of technologies are available right now, how easy they can be implemented on the Web, and what is the place of these technologies in large-scale Web-based education.

There have been significant advances in postharvest research over the last few decades that have led to the development of a diversity of appropriate technologies in many countries including several developing countries. This has greatly improved the handling and quality of food crops, and contributed significantly to improving nutrition and national development. Improvements have been made in ...

New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.

Continuous computing technologies are employed in order to achieve business continuity from the business operations perspective. In the same time, these technologies are the main prerequisite for business agility as agility relies on available information and “always-on” information system that generates it. Business Agility and relations with business continuity technologies are briefly explai...
