The damage that occurs around the tire bead region is one of critical failure forms a tire. Generally, prediction durability carried out by experimental method. However, it takes lot money and time to conduct experiments. Therefore, determine fatigue life radial bead, reasonable method proposed in this paper. Fatigue testing rubber compounds ΔSED-number cycle (Nf) was applied. maximum strain en...

Digestive vacuole (DV) formation in Paramecium can be separated into four steps: sequestration and recycling of the spent DV membrane, sweeping and concentrating of particles into the nascent DV, vacuole growth, and the release of the nascent DV. How the size, load and surface charge of solid particles affected formation and subsequently the digestive processes in log-phase cells were investiga...

The tire bead, as the most important load-bearing component at bead area, is closely related to durability of tire, but its structure developing slowly. For this reason, topological whole design was proposed, although it performs well, many defects existed due based on traditional experience. Therefore, paper studies topology shape optimization algorithm, delves into main criterion von Mises an...

The complex viscosity of planar star-branched polymers has been derived from general rigid bead-rod theory, but only for singly-beaded arms. Here, we explore the respective roles branch functionality, arm length, and nonplanar arrangements, analytically theory. For nonplanar, include polyhedral, both regular irregular. Further, all structures, compare with without central bead. We fit theory to...

This article describes a nanomanipulation technique that makes it possible to mechanically and quantitatively stretch and supercoil a single linear DNA molecule. We show how this technique can be extended to the study of protein–DNA interactions that lead to DNA untwisting, particularly to the study of promoter unwinding by RNA polymerase during the initiation of transcription. In our system, a...

We recently reported the use of a biphasic approach to generate topologically segregated bilayer beads. In generating 'one-bead one-compound' (OBOC) combinatorial libraries, novel encoding methods have been applied to these beads such as the testing library compound and the coding tags residing on the outer layer and inner core of each bead, respectively. In this report, we further exploit thes...

VASP comet sightings ess is more when it comes to actin-fueled propulsion. Julie Plastino, Stéphane Olivier, and Cécile Sykes (Institut Curie, Paris, France) show that hollow actin comets propel beads faster than a more filament-packed comet. Actin comets, which drive bead or bacteria movement, are thought to depend strongly on Arp2/3–built, branched actin networks. Now, Plastino et al. show th...

Protocols for characterizing cellular phenotypes commonly use chemical fixatives to preserve anatomical features, mechanically stabilize tissue, and stop physiological responses. Formaldehyde, diluted in either phosphate-buffered saline or phosphate buffer, has been widely used in studies of neurons, especially in conjunction with dyes and antibodies. However, previous studies have found that t...

Mallows and Shepp (2008) developed the following necklace processes. Start with a necklace consisting of one white bead and one black bead, and insert, one at a time, under a deterministic rule, a white bead or a black bead between a randomly chosen adjacent pair. They studied the statistical properties of the number of white beads by investigating the nature of the moments and the expected num...

We describe a new method for calibrating optical trapping measurements in which tension is applied in the direction of the laser beam to a molecule tethered between a surface and an optically trapped bead. Specifically, we present a generally-applicable procedure for converting from the measured scattering intensity and the measured stage displacement to applied tension and bead-coverslip separ...
