Image capturing

Materials science and engineering is a vital field of endeavor for industry and defense and also with regard to its sheer intellectual content. This field is no longer a disparate collection of disciplines. Its unity and coherence can be seen in a tetrahedron this image captures the essence of the field. The four aspects to any materials-related activity are as follows ... 

In the field of imaging, present-day software should use mouse-driven or menu-selectable commands to control the camera and allow real-time image capture. The latter feature allows the users to monitor the image buildup and trigger the capture at the best moment. Temperature control and exposure times should... 

The cold flow visualization shows the effects of active air forcing and liquid-fuel pulsations. Higher air flow rates, three times higher than those used in the combustion studies, were used for flow visualization. At the higher flow rates, the structures would be imaged more distinctly. The images captured show the... 

For common preclinical laboratory specimens such as mouse and rat, it is possible to image the skeletal features associated with different developmental stages of serial end-point harvested specimens (Fig. 1). Additionally, with the use of radio-opaque contrast agents, it is possible to image capture the soft tissue features of these specimens (Fig. 2). The combined imaging can be used to illustrate various anatomical features of interest within the same specimen (Fig. 3). This imaging technique therefore has an added potential of conferring multi-modality to an individual micro-CT machine. 

Staging parameters will vary according to manufacturer design layout (see Note 3). Specimen should be washed of all peripheral tissue to ensure that no irrelevant information is image captured. This can potentially confound the information content of the scan (see Note 4). Likewise, staging material should...

Pharmacological manipulation of heart function can be achieved in two ways in the semi-intact heart preparation. Flies can be fed various agents in their food followed, at some later time point, by an analysis of heart function. Alternatively, it is possible to apply the chemicals via the artificial hemolymph used to bathe the heart during the image capture. This latter method permits an assessment of acute effects on heart performance and a determination of the dose dependence of the effect (Fig. 3f).
