Visual images

Of all NTD methods for quality control of materials, products, welded and soldered joints the most informative and perspective are radioscopic ones that enable to obtain a visual image of an inner structure of a tested objects in real time under any projection. 

Threshold contrast is illustrated in Fig. 10-2. / is the intensity of light received by the eye from the object, and / + A/ represents the intensity coming from the surroundings. The threshold contrast can be as low as 0.018-0.03 and the object can still be perceptible. Other factors, such as the physical size of the visual image on the retina of the eye and the brain s response to the color of the object, influence the perception of contrast. 

Visual imaging of cell population in vitro) using low signal-to-noise ratio phase contrast microscopy can enable systematic monitoring measurements of cell quality, development and apoptosis. In the present study, microscopic evaluations as seen in Fig. 11 did not reveal any significant alteration in cellular morphology upto 1000 ng/ml. 

Scanning acoustic microscopy (SAM) is a relatively new technique which broke through in the mid-seventies and was commercialized recently. The SAM uses sound to create visual images of variations in the mechanical properties of samples. The ability of acoustic waves to penetrate optically opaque materials makes it possible to provide surface or subsurface stmctural images nondestmctively, which might... 

Surrealist artist Max Ernst defined collage as the "alchemy of the visual image." Students of his work have often dismissed this comment as simply a metaphor for the transformative power of using found images in a new context. Taking a wholly different perspective on Ernst and alchemy, however, M. E. Warlick persuasively demonstrates that the artist had a profound and abiding interest in alchemical philosophy and often used alchemical symbolism in works created throughout his career. 

Use this visual image to remember how to work with the distributive property ... 

Maurizio Calves addresses this conundrum. He was accused of being a Jungian, but he claims that he was simply interested in the visual images he found in Jung s Psychology and Alchemy (Calvesi 1993, xxi). 

Novel, pleasurable visual images are induced via catecholaminergic activation by for example mescaline and, although not yet established, dopaminergic D2 and D3 receptors may be particularly relevant. 

Analysis involves statistical techniques that may oversimplify wbWe producing compelling visual images. 

The upside of art is compelling. Many chemists think in a visual way, and many for whom English is a second language can assimilate concepts more easily if the words are presented in company with images. I think it most important that we use visual images heavily to convey physical chemistry. 

It really helped to develop visual images of things that we don t ordinarily see (i.e. Gas expansions and such)...
