"Don't let de paddle rollers catch you": punishment, control, and resistance in the slave South
This thesis explores the nature of white-slave relations in the U.S. South during the thirty-year period that preceded the Civil War. It asks one central question: How did slaveowners, overseers, patrollers, and nonslaveowners attempt to physically and psychologically punish slaves and control …

A novel surgical tool for stimulation paddle delivery to the dorsal root ganglion of the spine
… opposed to stimulating the entire dorsal column. Paddle stimulators have been shown to have more targeted therapy, are more energy efficient, and be more versatile by having a larger number of electrode contacts than traditional cylindrical leads. The major challenge with delivering a paddle …

Dissolution of different commercial aspirin tablets using a novel off-center paddle impeller (OPI) dissolution testing system
… Apparatus 2, termed "OPI" System for "off-center paddle impeller," in which the impeller is placed 8 mm off center in the vessel is tested to determine its sensitivity to differentiate between the dissolution profiles of differently formulated and manufactured tablets. Dissolution tests are …

What you see and what you are told: feedback does not diminish Action-Specific Perception
… act was manipulated by varying the size of the paddle used to block the ball. After each blocking attempt, participants performed a speed judgment task. Participants typically report the ball as moving faster when using a small paddle than when they use a big paddle. In Experiment 1, …

Effect of tablet compression on the dissolution of aspirin tablets using a novel off-center paddle impeller (opi) dissolution testing system
… dissolution system termed "OPI" for "off-center paddle impeller" was sensitive enough to determine differences in tablet dissolution profiles caused by different compression pressure during the tablet manufacturing process. The OPI Dissolution System simply consists of a modified Apparatus 2 in …

Paddle faster I hear techno music: mapping the prehomosexual and the posthomosexual in the souths of James Dickey and Samuel R. Delany
This thesis argues that James Dickey’s Deliverance, and Samuel R. Delany’s Through the Valley of the Nest of Spiders are works of speculative Southern fiction by reading them through David Halperin’s “How to do the History of Male Homosexuality” and his notion of prehomosexual discourses. It begins …
