Gauge Repeatability And Reproducibility Study For A Bulge Test Fixture For Corrugated Boxes, Anthony J. Hall

Industrial Technology and Packaging

This senior project evaluates the measurement variation within a corrugated container bulge tester by utilizing a gauge repeatability and reproducibility study. Bulge is a type of deformation containers experience when subject to compressive forces such as stacking or internal forces due to under- and over-packaging. Both compressive and internal forces can accelerate the failure of a container by causing panels to flex and flutes to buckle, compromising structural integrity. Additionally, variable environmental conditions such as temperature and humidity can magnify the effect bulge has on a container, speeding up the failure rate of a container.

Eating Rate During A Fixed-Portion Meal Does Not Affect Postprandial Appetite And Gut Peptides Or Energy Intake During A Subsequent Meal, J. Phillip Karl, Andrew J. Young, Scott J. Montain

United States Army: Publications

Eating rate has recently been shown to influence energy intake and appetite during an ad libitummeal, and alter postprandial secretion of glucagon-like peptide-1 (GLP-1) and peptide-YY (PYY) following a fixed-portionmeal. Whether these effects influence satiety, as measured by energy intake at the subsequent meal, is unclear. We manipulated eating rate during a fixed-portion meal in order to examine how eating behavior and associated periprandial and postprandial responses of putative endocrine mediators of appetite would affect energy intake at the following meal in fifteen non-obese (BMI ≥ 25 kg/m²) and ten obese (BMI ≥ 30 kg/m²) healthy adult men and …

Effects Of Gage Length, Loading Rates, And Damage On The Strength Of Ppta Fibers, Jaeyoung Lim, James Q. Zheng, Karl Masters, Weinong W. Chen

United States Army: Publications

Axial tension and transverse compression experiments on single fibers were performed to investigate the mechanical behavior of three high-performance fibers (Kevlar ®, Kevlar ® 129, and Twaron ®) with diameters in the order of 9-12 μm. The single fibers were manufactured from 1998 through 2008. A miniaturized tensile Kolsky bar was used to determine the tensile response of PPTA single fibers at a high strain rate. Gage length and strain rate were found to have minimum effects on the tensile strength of PPTA single fibers. Manufacturing time over a decade was found to have negligible effects on the tensile strength …
