Abstract There are a wide variety of dressing techniques and materials available for management of both acute wounds and chronic non-healing wounds. The primary objective in both the cases is to achieve a healed closed wound. However, in a chronic wound the dressing may be required for preparing the wound bed for further operative procedures such as skin grafting. An ideal dressing material should not only accelerate wound healing but also reduce loss of protein, electrolytes and fluid from the wound, and help to minimize pain and infection. The present dictum is to promote the concept of moist wound healing. This is in sharp contrast to the earlier practice of exposure method of wound management wherein the wound was allowed to dry. It can be quite a challenge for any physician to choose an appropriate dressing material when faced with a wound. Since wound care is undergoing a constant change and new products are being introduced into the market frequently, one needs to keep abreast of their effect on wound healing.

How fast is human perception? Visual system Visual perception How long does it take us to be aware of what we see? In addition to only having a very limited sharp field of vision, our eyes are also fairly slow at registering changes in images compared to the update frequency of a modern computer screen. Research has shown that the retina needs to see a new image for about 80 ms before that image is registered in normal light conditions.
The ability to register an image is also dependent on the light intensity of that image. This can be compared with a photographic camera where a short shutter speed in a badly lit environment results in a dark and blurred image, where hardly anything can be seen. However, when taking an image of something that is very well lit, e. In addition to needing time to register an image, the eye also requires time for the image to disappear from the retina.
This is also dependent on the light intensity. One example of this is when exposed to a very bright light such as a camera flash where the image of the flash stays on the retina long after the flashing has ended. When reading in normal light conditions, it has been observed that most people only need to see a word for between 50—60 ms in order to perceive it. However, when looking at, for instance, a picture people need to see it for more than ms before being able to interpret what they are seeing.

It was the first permanent IBM installation in the world to do scientific work Comrie’s Greenwich setup had not been permanent. In late , Eckert presented a paper on this work to the American Astronomical Society. A seemingly mundane but significant aspect of this work was the new ability to feed the result of one computation into the next and print the results of these calculations directly, thus eliminating the transcription errors that were common in astronomical and lunar tables [ 17 ].
To illustrate with a quote from Kay Antonelli, University of Pennsylvania, referring to her wartime work [ 34 ], “We did have desk calculators at that time, mechanical and driven with electric motors, that could do simple arithmetic. You’d do a multiplication and when the answer appeared, you had to write it down to reenter it into the machine to do the next calculation.

Send email to admin eh. Yet even beyond its shear size, the aerospace industry was one of the defining industries of the twentieth century. As a socio-political phenomenon, aerospace has inflamed the imaginations of youth around the world, inspired new schools of industrial design, decisively bolstered both the self-image and power of the nation state, and shrunk the effective size of the globe.
As an economic phenomenon, aerospace has consumed the major amount of research and development funds across many fields, subsidized innovation in a vast array of component technologies, evoked new forms of production, spurred construction of enormous manufacturing complexes, inspired technology-sensitive managerial techniques, supported dependent regional economies, and justified the deeper incursion of national governments into their economies.
No other industry has so persistently and intimately interacted with the bureaucratic apparatus of the nation state.

The papers discuss the critical issues related to the scientific and technical aspects of the protection and conservation of the cultural heritage of Europe. Participants of the symposium identify and describe the main research and development issues that are common to cultural heritage problems, and increase cooperation in these areas. Other papers examine the applicability of research and development through better matching with the real needs of conservators, restorers, policy makers, and the general public.
The participants also discuss specific research and development directions for the future, including the provision of a scientific basis for European Community policies on environment and culture. One paper presents some of the scientific research done both in the field and laboratory of specific historical areas, monuments, indoor objects. As an example, archaeologists can use infrared thermal image analysis as an enhanced tool to detect buried archeological and historical sites.
Another paper analyzes the chemical and physical properties of deteriorated stones in historical monuments in Castile-Leon. The collection can prove useful for archaeologists, historians, museum curators, and policy makers involved in national and cultural preservation.
