- Title
- Resulting Hydraulic Jump From Oscillatory Forces Acting on a Pipe.
- Creator
- Wehage, Tim, Caracci, Christian, Mechmet, Bryan, Garzon, Julian, Su, Tsung-Chow, College of Engineering and Computer Science
- Abstract/Description
-
Within the framework of ongoing research studying the effects of oscillatory forces on pipe flow, an experiment was conducted to investigate the relationship between the nature of said forces and hydraulic jump resulting from the impact of the exiting flow onto an orthogonal surface. To this end, a reservoir supplying constant head and near-hydrostatic conditions was equipped with an exit fitting in its lower section. A section of PVC tubing extended vertically downward from this exit point...
Show moreWithin the framework of ongoing research studying the effects of oscillatory forces on pipe flow, an experiment was conducted to investigate the relationship between the nature of said forces and hydraulic jump resulting from the impact of the exiting flow onto an orthogonal surface. To this end, a reservoir supplying constant head and near-hydrostatic conditions was equipped with an exit fitting in its lower section. A section of PVC tubing extended vertically downward from this exit point and was straddled by a pair of dynamic loudspeakers placed opposite each other and connected to a receiver's inputs so as to play a signal of specified frequency. The resulting turbulent jet flow was then allowed to drop to a horizontal plate of circular shape. The outer lip of the plate triggered a circular hydraulic jump whose location was found to be directly dependent on the frequency of the forces exciting the flow.

- Title
- "Tiger Stripe" Phenomena in Indian River Lagoon Dolphins.

- Abstract/Description
-
A previously undescribed skin abnormality, which we refer to as “tiger stripes,” has been identified in Indian River Lagoon bottlenose dolphins through photo-identification surveys. The condition presents as parallel stripes on the ventral and lateral aspects on the torso of the dolphin with varying length and depth. The condition may be indicative of rapid weight loss, similar to human "stretch marks”, debilitating illnesses resulting in emaciation or a result of starvation due to lack of...
Show moreA previously undescribed skin abnormality, which we refer to as “tiger stripes,” has been identified in Indian River Lagoon bottlenose dolphins through photo-identification surveys. The condition presents as parallel stripes on the ventral and lateral aspects on the torso of the dolphin with varying length and depth. The condition may be indicative of rapid weight loss, similar to human "stretch marks”, debilitating illnesses resulting in emaciation or a result of starvation due to lack of prey. Goals of this study were to determine if tiger stripes are: (1) a marker of rapid weight loss, (2) more prevalent in post-partum females, and to (3) examine the spatial and temporal distribution in the IRL. Preliminary findings indicate that tiger striping is a useful marker suggestive of rapid weight loss. The next phase of research is to determine if the condition can be utilized as a pre-mortem marker of emaciation in IRL dolphins.

- Title
- Pentraxin 3 Reactivity to Acute Exercise in Obese Individuals.
- Creator
- Maharaj, Arun, Urtula, Alyssa M., Slusher, Aaron L., Mock, J. Thomas, Fisher, Craig B., Huang, Chun-Jung
- Abstract/Description
-
Pentraxin 3 (PTX3) has been demonstrated as a vital biomarker for chronic inflammatory diseases. Decreased plasma PTX3 has been observed in obese populations. However, no studies have examined the impact of obesity on PTX3 reactivity to exercise. Therefore, our study sought to investigate PTX3 plasma response to maximal exercise in obese and normal-weight subjects, and its relationship with insulin sensitivity. Twenty-one subjects (9 obese and 12 normal-weight) were recruited. Plasma PTX3,...
Show morePentraxin 3 (PTX3) has been demonstrated as a vital biomarker for chronic inflammatory diseases. Decreased plasma PTX3 has been observed in obese populations. However, no studies have examined the impact of obesity on PTX3 reactivity to exercise. Therefore, our study sought to investigate PTX3 plasma response to maximal exercise in obese and normal-weight subjects, and its relationship with insulin sensitivity. Twenty-one subjects (9 obese and 12 normal-weight) were recruited. Plasma PTX3, insulin, and glucose levels were measured before and following exercise. While our results showed lower resting PTX3 levels in obese subjects, exercise elicited similar elevations in PTX3 and insulin sensitivity in both groups. Furthermore, PTX3 area-under-curve (AUC) was correlated with glucose AUC, even when controlled for body mass index and fitness level. These findings suggest that glucose may potentially regulate PTX3 response to exercise. Further investigation is needed to verify the impact of substrate utilization on exercise-induced PTX3 elevation.
