Asphalt mixture is heterogeneous in nature; therefore, macroscopic parameters alone cannot describe the mechanical behavior of the mixture. In recent years, the arrangement of the aggregate particles in terms of spatial and directional distributions, and contact points are considered as the internal structure of asphalt. The main purpose of this paper is to investigate the microstructural chara...

Developing chick myotubes in tissue culture were freeze-fractured to yield complementary replicas of large areas of membrane. Regions of muscle fibers with high concentrations of acetylcholine receptors were identified by binding of fluorescent-labeled alpha-bungarotoxin. Membranes in such regions contained clusters of large (100 A Diam) angular particles, similar in appearance to particles fou...

Particles 30 to 40 A in diameter are attached to the external surface of negatively stained membrane vesicles formed by the ATPase of sarcoplasmic reticulum. These particles are identical with the surface particles of isolated, intact sarcoplasmic reticulum first described by Ikemoto et ~2. (IKEMOTO, N., SRETER, F. A., AND GERGELY, J. (1966) Fed. Proc. 25, 465). Tryptic digestion was used in an...

For an internally unstable soil, fine particles can move in the pore channels between coarse along with seepage flow; this process is termed internal erosion. To evaluate stability and erosion behavior of sandy gravel alluvium beneath suspended cutoff wall embankment dam foundation, a series horizontal tests were carried out on four representative gradations layer using large-scale high-pressur...

We study the set of all pseudoline arrangements with contact points which cover a given support. We define a natural notion of flip between these arrangements and study the graph of these flips. In particular, we provide an enumeration algorithm for arrangements with a given support, based on the properties of certain greedy pseudoline arrangements and on their connection with sorting networks....

Abstract Pyrolysis is an oxygen-free process for the thermal decomposition of raw materials. The heat conduction and flow pyrolysis products (i.e., gas fraction liquid vapour generated during pyrolysis) influence products. In this work, orientation wooden particle fibres with respect to direction source on dynamics was investigated, where there were two sizes oriented along or across source. no...

Two-dimensional arrays of gold nanoparticles with a periodicity commensurate with the wavelength of resonant excitation of localized plasmons have been shown to exhibit a strong long-range interaction between particles. We investigate experimentally the effect of varying the degree of disorder in the geometrical arrangement from a periodic to a disordered lattice with constant occupancy. We als...

We present the experimental observation of polarization entanglement for three spatially separated photons. Such states of more than two entangled particles, known as GHZ states, play a crucial role in fundamental tests of quantum mechanics versus local realism and in many quantum information and quantum computation schemes. Our experimental arrangement is such that we start with two pairs of e...

The structure-directing influence of static and dynamic, i.e. rotating, magnetic fields on the orientational alignment of spindle-type hematite particles with a high aspect ratio is investigated. Structural characterization using electron microscopy and small-angle X-ray scattering confirms a nearly collinear particle arrangement with orientation of the main particle axis either parallel or per...
