3D printing is a promising technology for creating polymer objects of given architecture with specified functional properties. In fact, the choice filaments quite limited. Here, we report process producing polystyrene 0.0025–2 wt.% single-walled carbon nanotubes (SWCNTs) by extruding crushed composites. The resulting are characterized high uniformity filler distribution and absence air pores. C...

2A12 aluminum alloy is a high-strength aerospace alloy. During its extrusion process, the process parameters have great impact on microstructure evolution of extruded products. There are three controlled in actual project, which initial temperature billet, die and speed. Combined with back propagation (BP) neural network finite element method (FEM) simulation, based constitutive equation recrys...

The genetic algorithm (GA) has been applied to a wide variety of problems where truly optimal solutions are computationally intractable. One such problem is the book embedding problem from graph theory. A book embedding is an ordering of vertices along a line (the spine) with the edges embedded in half-planes (the pages) extruding from the line so that the edges do not cross. The goal is to fin...

Snacks were produced by extruding blends of partially-defatted soybean flour with flours from milled or parboiled African-grown rice. The interplay between composition and processing in producing snacks with a satisfactory sensory profile was addressed by e-sensing, and by molecular and rheological approaches. Soybean proteins play a main role in defining the properties of the protein network i...

Rumpal, Nidhi and Gregory A. Lnenicka. Ca clearance at growth cones produced by crayfish motor axons in an explant culture. J Neurophysiol 89: 3225–3234, 2003; 10.1152/jn.00952.2002. Intracellular free Ca concentration ([Ca ]i) plays an important role in the regulation of growth cone (GC) motility; however, the mechanisms responsible for clearing Ca from GCs have not been examined. We studied t...

BACKGROUND To maintain a protective barrier, epithelia extrude cells destined to die by contracting a band of actin and myosin. Although extrusion can remove cells triggered to die by apoptotic stimuli, to maintain constant cell numbers, epithelia extrude live cells, which later die by anoikis. Because transformed cells may override anoikis and survive after extrusion, the direction of extrusio...
