Production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. This is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. Initially, unsuitable surface roughness, the friction between rolls and the st...

We discuss the use of subdivision surfaces in the procedural design of imprint rolls for use in the roller imprinting process. Roller imprinting is being developed for the fabrication of microfluidic devices in polymer substrates. Imprint rolls are modeled using Catmull-Clark subdivision surfaces, and are procedurally designed based on feedback from finite-element simulations of the imprinting ...

Face-selective neurons were discovered in the inferior temporal visual cortex by Perrett et al. (1982), in the amygdala by Sanghera, Rolls, and Roper-Hall (Sanghera et al. 1979; Rolls 2011) and Leonard et al. (1985), and in the orbitofrontal cortex by Rolls et al. (2006). These neurons respond 2–20 times more to the best face compared to the best nonface, and different brain regions provide the...

A simple model to explain the numerically observed behavior of chaotically varying stripes and square patterns in zero-Prandtl-number convection in Boussinesq fluid is presented. The nonlinear interaction of mutually perpendicular sets of wavy rolls, via higher-order modes, may lead to a competition between the two sets of rolls. The appearance of square patterns is due to a secondary forward b...

during a survey on pistachio, pistacia vera l., pests in isfahan, iran, in 2015, some lepidopteran larvae living and feeding inside galls of the wrinkling pistachio aphid, forda hirsuta mordv., were observed. after laboratory rearing of these larvae, the moths were identified as altenia mersinella (staudinger, 1879) (lep.: gelechiidae) by the third author. this species has previously been repor...

Stable localized roll structures have been observed in many physical problems and model equations, notably in the 1D Swift–Hohenberg equation. Reflection-symmetric localized rolls are often found to lie on two “snaking” solution branches, so that the spatial width of the localized rolls increases when moving along each branch. Recent numerical results by Burke and Knobloch indicate that the two...

3.1 ABSTRACT A randomized complete block design with four treatments (100% pale, soft, and exudative (PSE), 100% PSE + 1.5% chicken collagen, 100% normal, and 100% normal + 1.5% chicken collagen) and six replications was utilized to test the effects of raw material and chicken collagen on protein functionality in the formulation of chunked and formed broiler breast. Addition of 1.5 % chicken co...
