Particle-streak method

Motivation and Principle. Broadened reflections are characteristic for soft matter. The reason for such broadening is predominantly both the short range of order among the particles in the structural entities, and imperfect orientation of the entities themselves. A powerful method for the separation of these two contributions is Ruland s streak method [30-34], Short range of order makes that the reflection is considerably extended in the radial direction of reciprocal space - often it develops the shape of a streak. This makes it practically possible to measure reflection breadths separately on several11 nested shells in reciprocal space. As a function of shell diameter one of the contributions is constant, whereas the other is changing12. If the measurement is performed on spheres (azimuthal), the orientation component is constant. 

Blending technology offers methods for producing higher esthetic value materials, e.g., films or coatings without gel particles (or fish eyes ), moldings with streak-free surface finish, etc. 

In hypercholesterolemic patients, LDL uptake by tissues is inhibited due to an inherited defect or absence of LDL receptors resulting in extremely high levels of plasma total and LDL-cholesterol (Brown and Goldstein, 1986). Cholesterol from LDL is deposited into blood vessels by a scavenger method and may contribute to the development of atherosclerosis in these individuals. Altered LDL particles can also be taken up by macrophages via a modified receptor method preferentially over the LDL receptor method in tissues. This may lead to the development of foam cells and fatty streaks in the blood vessels, early indicators of the atherosclerotic process (Steinberg et al., 1989).
