the influence of 0-27 g/100g of full-fat soy flour (ffsf), 31-35g/100g of water content and extrusion conditions on the textural characteristics of spaghetti were evaluated. process was performed with screw speed of 10-40 rpm and water circulating temperature of 35-70°c. this enrichment resulted in significant differences in mechanical strength and cutting parameter. based on the mixture surfac...

PLA is one of the most promising bio-compostable and bio-degradable thermoplastic polymers made from renewable sources. PLA is generally produced by ring opening polymerization (ROP) of lactide using the metallic/bimetallic catalyst (Sn, Zn, and Al) or other organic catalysts in a suitable solvent. In this work, reactive extrusion experiments using stannous octoate Sn(Oct)2 and tri-phenyl phosp...

The antiapoptotic protein Bcl-2 plays important roles in Ca(2+) signaling by influencing inositol triphosphate receptors and regulating Ca(2+)-induced Ca(2+) release. Here we investigated whether Bcl-2 affects Ca(2+) extrusion in pancreatic acinar cells. We specifically blocked the Ca(2+) pumps in the endoplasmic reticulum and assessed the rate at which the cells reduced an elevated cytosolic C...

The kinetic properties of cruciform extrusion in supercoiled DNA molecules fall into two main classes. C-type cruciforms extrude in the absence of added salt, at relatively low temperatures, with large activation energies, while S-type cruciforms exhibit no extrusion in the absence of salt, and maximal rates at 50 mM NaCl, with activation energies about one quarter those of the C-type. These di...

Cells of Porphyra perforata, a red marine alga, accumulate K in the absence of concomitant Na or Li extrusion while immersed in Li- or Mg-sea waters lacking Na. This suggests that the coupling observed between K and Na transport is facultative. No evidence is obtained for net extrusion of Li. Na efflux, with the concentration gradient, is facilitated by K and is proportional to the cellular Na ...

Abstract The extrusion speed and deformation temperature are important factors affecting the microstructure development during deformation. Microstructure plays a crucial role in performance of mechanical properties materials. In direct extrusion, homogeneous evolution length extruded bar could be affected due to its non-isothermal exit evolution. Thus, new set-up is suggested with real-time co...

The study was conducted to develop castor oil – graphite lubricants for cold extrusion of aluminium alloy and to investigate the effect of the developed lubricant on the extrusion pressure of aluminium alloy. Cold extrusion process at a constant extrusion ratio of 1.25:1 was used on 14mm diameter by 30mm long aluminium alloy billets. Experimental results showed that onset pressure ranges from 1...

Recently, with a broadening range of available materials and alteration of feeding processes, several extrusion-based 3D printing processes for metal materials have been developed. An emerging process is applicable for the fabrication of metal parts into electronics and composites. In this paper, some critical parameters of extrusion-based 3D printing processes were optimized by a series of exp...
