Development of a tri-axial (vertical and shear) force measurement foot platform
… the world. It has long been thought that shear stresses on the plantar surface of the foot are a major contributing factor to the formation of these ulcers. Although there are many instruments available that measure the vertical foot pressure (vertical forces), there are currently no …

The effect of dynamic shear force on chondrocyte biosynthesis in agarose gels
… network, which accounts for the tensile and shear stiffness of the cartilage. Due to the avascular, aneural, and alymphatic nature of cartilage, its native cells (chondrocytes) have limited regeneration capabilities after injury. Previous investigators discovered that dynamic compressive …

Shear force impacts type IV pilus and flagellar dynamics during Pseudomonas aeruginosa surface adhesion
Surface-attached bacteria experience forces associated with fluid flow in nature. However, many studies on bacterial adhesion have been conducted in conditions either lacking flow or using forces not typically found in natural systems. In Chapter 2, I examine how Pseudomonas aeruginosa cells use …

Relationship between cooking rate and Warner-Bratzler shear force from pork chops cooked to two degrees of doneness
… between cook rate and Warner-Bratzler shear force (WBSF) values of pork chops cooked to two degrees of doneness (DoD) (N=503 for 63⁰C and N=357 for 71⁰C). Ventral loin and chop quality traits were measured on loins after aging 14 d. Chops were cooked on Farberware open-hearth grills …

Evaluation of rapid evaporative ionization mass spectrometry (REIMS) for the prediction of slice shear force and biochemical markers of tenderness in beef Longissimus lumborum steaks
… (REIMS) as a rapid method to predict slice shear force (SSF) and biochemical markers of beef tenderness. Steak samples were randomly collected from beef carcasses (Canada AA, n = 1505; Canada AAA, n = 1363) over a three-year period. Steaks were aged for 14 d, then tenderness was determined …

Factors Affecting the Textural Properties of Pork
… was very tender at 1 d postmortem with a mean shear value of 2.9 kg; however, there was a lot of variation around the mean. Shear force decreased about 20% from 1 to 14 d postmortem (P < 0.05). Correlations between shear force and the measured quality traits were inconsistent across aging days …

Mechanisms of mesothelial tissue lubrication
… sliding between the lung and chest wall induces shear stress that could damage the delicate mesothelial cells covering the tissue surfaces. Normally, the pleural space, which is filled with fluid, is able to sustain continuous shear loading throughout its lifetime. To understand the mechanisms in …

The Role of Force-Sensitive Interactions in Amyloid Assembly by Fungal Adhesins
… and T domains prior to amyloid assembly, and shear force-induced partial unfolding of the Als protein is required to expose its AFR, allowing amyloid formation to proceed. We investigated this putative mechanism by examining the relationship between the stability of AFR-concealing …

Quantifying the Effects of Microbial Phytase and Diet Acidity on Ca and P Utilization by Weanling Pigs
… P diets linearly increased ADG (P < .001), rib shear force (P < .01), shear energy (P < .02), ash weight (P < .001) and ash percent (P < .001), Ca (P < .001) and P (P < .001) digestibility and digestible Ca (P < .001) and P (P <.001). Added P linearly increased ADG (P < .003), rib shear force (P …

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures
A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in-situ crosshead away from the supports. Two …
