Efficacy of various sanitizers against Salmonella during simulated commercial packing of tomatoes.
TLDR
Six commonly used sanitizer treatments were assessed to reduce Salmonella on tomatoes, in wash water, and on equipment surfaces using a pilot-scale processing line, with chlorine plus citric acid yielding the greatestSalmonella reduction on tomatoes.
Salmonella transfer during pilot plant scale washing and roller conveying of tomatoes.
TLDR
Adding peroxyacetic acid or chlorine to the wash water significantly decreased cross-contamination during tomato conveying, with chlorine less effective in controlling Salmonella on foam compared with plastic and brush rollers.
Density functional theory of equilibrium random copolymers: application to surface adsorption of aggregating peptides.
TLDR
It is shown that, for attractive surfaces, there is evidence of significant enhancement of protein aggregation, a consequence of a surface phase transition, which has been shown to occur with ideal equilibrium polymers in the presence of sufficiently attractive surfaces.
Exact evaluation of the depletion force between nanospheres in a polydisperse polymer fluid under Θ conditions.
TLDR
An exact theory is developed to describe the potential of mean force between the spheres for the case where the polymer molecular weight dispersity is described by the Schulz-Flory distribution and it is found that even when q = R(g)/R(s) ⪆ 10, then the use of a monopole expansion for the polymer end-point distribution about the spheres is sufficient.
Concurrent Aerospace Thermoplastic Stiffened Panel Conceptual Design and Cost Estimation Using Knowledge Based Engineering
TLDR
A methodology is presented to estimate aerospace stiffened panel cost within conceptual design phase based on the Knowledge-Based Engineering (KBE) technique and an approach of using cost primitives for cost calculation is proposed.
