2.2 The inventive drive

What events and ideas spurred people to come up with thousands of inventions in the last 100 years?

Ron Hickman was a do-it-yourself enthusiast who damaged a chair being used to support a piece of wood he was sawing. Instead of merely being annoyed at the accident he set about designing and building a prototype of a combined workbench and sawhorse to prevent further damage to his furniture. This became the Workmate (Author(s): The Open University

Figure 1 showed two spiral galaxies: NGC 5548, which has an active nucleus, and NGC 3277 which does not. If we accept that AGN are the result of accretion on to supermassive black holes at the centres of the galaxies which harbour them, it is natural to ask the question whether galaxies like NGC 3277, which do not

Conclusion

  1. Many rivers are fed by springs, which occur at points where groundwater reaches the surface. Springs can occur in different geological settings, forming valley springs, stratum springs or solution channel springs.

  2. The water in a river originates from overland flow, from interflow and from baseflow. Baseflow forms a higher proportion of river water in summer than in winter, and in rivers flowing over good aquifers.

Endoscopy as a Tool in Architecture
The European Architectural Endoscopy Association was established in connection with the Association?s first international conference on August 25-28, 1993, which was hosted by the Department of Architecture at the Tampere University of Technology. The purpose of the EAEA is to promote experimentation, research, communication, exchange of experiences, collaboration, user participation and teaching in the field of endoscopy and environmental simulation. The first EAEA conference was attended by 25

2.5.1 Physical and weather-related indicators

The indicators collected in Table 4 have been observed to change over large regions of the Earth during the 20th century. According to the TAR, there is now a good level of confidence that what is being recorded is the result of long-term change rather than short-term natural fluctuations. As we noted earlier (Section 2.2.2), the most recent period of warming has been almost global in extent, but particularly marked at high latitudes. So are the changes in Table 4 consistent with rising tempe

Introduction

This unit is concerned with a special class of topological spaces called surfaces. Common examples of surfaces are the sphere and the cylinder; less common, though probably still familiar, are the torus and the Möbius band. Other surfaces, such as the projective plane and the Klein bottle, may be unfamiliar, but they crop up in many places in mathematics. Our aim is to classify surfaces – that is, to produce criteria that allow us to determine whether two given surfaces are h

The objetive of the proyect is the hiperrealistic simulation of scenarios on standard PCs. We use the same tools that are used by the entertainment industry (3d graphics engines) to get the highest level of realism possible in 3d worlds. By now, we are exploring only the audio and visual areas.

2.4 Obesity – an evolutionary perspective

If you were now to take a broader biological approach to the data discussed in the previous section you might still be puzzled. Excess body weight leads to a variety of diseases, including diabetes, osteoarthritis and so on – surely this must reduce overall biological fitness.

Through the game ?engine? tools, virtual spaces can be achieved according to an editor?s criterium. Thus, a varied range of uses in different research fields are permitted.

Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to supp
In this paper, definitions of collaborative design are discussed and understood in terms of a designer?s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon?s reflective practice theory, Valkenburg and Dorst?s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating signific

Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organism

6 Everyone's interests

So far we have seen that the MMR debate has been far from neutral, with collective and individual values playing a part in decision making – by scientists, policy makers and parents. One angle of the debate has been a preoccupation with conflicts of interest. With researchers increasingly reliant on funding from sources that have clear interests in the outcome, openness and transparency about who funds what research is deemed essential so that reviewers can take this into account when asses
