In this paper, we explore regional innovation in the use of varieties of algae as inputs to industrial processes. It is important to understand that algae are one of nature's most bountiful products, with an almost infinite variety of applications. Algae have received prominence in the research literature because of the strong evidence that they can make a major contribution to the production and—importantly—storage of renewable energy. Following the introduction to this paper, Section 2 reviews the nature and application of algae in two main aspects of clean energy production: first as biogasolene or biodiesel; second as large-scale storage batteries for electricity. The latter is particularly important as one classic deficiency of electricity is the difficulty in storing it for lengthy periods other than in short-life batteries. However (Section 3), there are other uses for algae, ranging from aquaculture to medicine and the production of cosmetics. In the southwest corner of the Iberian Peninsula, between Faro in Portugal through Huelva to Cadiz in Spain, is a significant research and commercial algae production zone. The paper describes the key system elements in play in this trans-border innovation network and considers prospects for new path creation towards biofuels, the main research and application centres for which are in the San Francisco Bay Area in California. Conclusions and recommendations for policy action are then drawn. 相似文献

A set of contemporary and increasingly urgent environmental problems in the USSR are surveyed, emerging as a result of continued development and technological change and mandating, in effect, a new environmental agenda. Analysis of specific problems reveals ways in which the new agenda must differ from the old: it must be more ecologically based, more comprehensive, and more global in scope. A concluding section examines how this agenda appears to be evolving over time, and identifies components which will be essential in order for it to effectively address the environmental challenges of the next century. 相似文献

Single‐sheet charters and coin epigraphy provide valuable evidence for the development of representations of the Old English dental fricative in the seventh and eighth centuries. This evidence indicates differing Kentish and Mercian practices up to the 780s, when scribes in both areas rapidly adopt <ð> to represent this sound. In Kent, occasional experimentation with this character from perhaps as early as the reign of Eadbald (616–40 ad ) may suggest a lengthy period of gradual adoption prior to the rapid increase. Mercian practice instead shows an abrupt adoption, which is perhaps the result of reform according to external (perhaps Kentish) models. 相似文献

SURVEY of a field, immediately north of the early Norman motte-and-bailey castle of Hen Domen, Montgomery, revealed ridge-and-furrow, averaging 4 m. in width, cut by the outer ditch of the bailey. Excavation demonstrated that the ridge-and-furrow extended under the inner rampart of the bailey. Pollen analysis of the buried soil showed the former presence of cereals and the weeds of cultivation. A Carbon-14 date from charcoal in the buried soil reinforced the view that this field-system was in use before the Norman conquest. 相似文献

SUMMARYJeremy Bentham has two very strong commitments in his thought: one is to the principle of utility, or the greatest happiness principle, as the fundamental principle of morality; the other is to truth, as indicated, for instance, in his opposition to falsehood and fiction in the law. How, then, did Bentham view the relationship between utility and truth? Did he think that utility and truth simply coincided, and hence that falsehood necessarily led to a diminution in happiness, and conversely truth led to an increase in happiness? This article addresses this issue through two bodies of material: the first consists of Bentham's writings on religion under the heading of ‘Juggernaut’ and dating from 1811 to 1821; the second consists of the writings on judicial evidence dating from 1803 to 1812 and which appeared in Rationale of Judicial Evidence. 相似文献
