Eurther videomicroscopy investigations were conducted for model systems consisting of binary mixtures of pure nonionic surfactants [10]. The results indicated that the common source of the intriguing phenomena described above is that the more hydrophilic species dissolve faster, causing the remaining drop to become enriched in the less hydrophihc species, which are less soluble and dissolve more slowly. Indeed, the drop can achieve compositions... 

The importance of a surfactant - rich phase, particularly a lamellar one, to detergency performance was noted for liquid soils such as C16 and mineral oil (3.6). Videomicroscopy experiments indicated that middle phase microemulsion formation for C12E04 and Cjg was enhanced at 30 °C, while at 18 °C, oil - in - water, and at 40 °C, water - in - oil microemulsions were found to form at the oil - bath interface (3.6). A strong temperature dependence of liquid soil removal by lamellar liquid crystals, attributed to viscosity effects, has been noted for surfactant - soil systems where a middle - phase microemulsion was not formed (10).

The methods described below outline three dynamic adhesion/aggregation assays used to assess the in vitro and/or ex vivo efficacy of platelet antagonists (1) a viscometric-flow cytometric assay to measure shear-induced platelet-platelet aggregation in the bulk phase, (2) a perfusion chamber coupled with a computerized videomicroscopy system to visualize in real time and quantify (a) the adhesion and subsequent aggregation of platelets flowing over an immobilized substrate (e.g. extracellular matrix protein) and (b) free-flowing monocytic cell adhesion to immobilized platelets.

Videomicroscopy of Two-Phase Steady Cocurrent Flow in a Model Porous Medium... 

A novel flow cell has been developed to observe on a microscopic level the steady state, cocurrent flow of two pre-equilibrated phases in a porous medium. It consists of a rectangular capillary tube packed with a bilayer of monodisperse glass beads 109 microns in diameter. The pore sizes in the model are of the order of magnitude of those in petroleum reservoirs. An enhanced videomicroscopy and digital imaging system is used to record and analyze the flow data.

Several lines of evidence indicate that active motility of tumor cells is required in the metastatic process. The metastatic potential of Dunning R-3327 rat prostatic adenocarcinoma sublines best correlates with their ability to move on a substrate, as assessed either by a visual grading system of time-lapse videomicroscopy, or by a computerized mathematical system using spatial temporal Fourier analysis (Mohler, 1993). Similarly, the high metastatic capacity of a v-fos-transfected rat fibrosarcoma cell line corre-...
