Autonomic dysreflexia (AD) can occur during penile vibratory stimulation in men with spinal cord injury, but this is variable, and the association with lesion level is unclear. The purpose of this study was to characterize the cardiovascular responses to penile vibratory stimulation in men with spinal cord injury. We hypothesized that those with cervical injuries would demonstrate a greater deg...

Vocal fold disorders affect 3-9% of the U.S. population. Tissue engineering offers an alternative strategy for vocal fold repair. Successful engineering of vocal fold tissues requires a strategic combination of therapeutic cells, biomimetic scaffolds, and physiologically relevant mechanical and biochemical factors. Specifically, we aim to create a vocal fold-like microenvironment to coax stem c...

OBJECTIVE To describe normal vocal fold vibratory characteristics recorded with high-speed digital imaging (HSV) of the larynx. DESIGN Prospective study of healthy subjects who volunteered to undergo laryngeal HSV and videostroboscopy. Image analysis was randomly assigned to 3 blinded raters. SETTING Community-based clinic with a specialty in laryngology. PARTICIPANTS Fifty healthy subjec...

We investigated the extent to which subjects' ability to perceive the fine spatial structure of a stimulus depends on its temporal properties (namely the frequency at which it vibrates). Subjects were presented with static or vibrating gratings that varied in spatial period (1-8 mm) and vibratory frequency (5-80 Hz) and judged the orientation of the gratings, presented either parallel or perpen...

AIM The purpose of this study was to assess the knowledge and practices of Saudi dentists in finishing and polishing composite restorations. MATERIALS AND METHODS A cross-sectional questionnaire-based study was conducted among 306 Saudi dentists from March to April 2012. The collected data were analyzed using Microsoft Excel 2010 program and descriptive statistics were obtained. RESULTS Com...

Magnetic abrasive machining is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible. The aim of this paper is to study maximum efficiency in terms of material removal rate with respect to magnetic flux density ...

PURPOSE We evaluated ejaculatory response and semen quality in 653 trials of penile vibratory stimulation in 211 men with spinal cord injury, and compared results with low versus high amplitude vibratory stimulation. MATERIALS AND METHODS Low and/or high amplitude penile vibratory stimulation was performed 1 to 27 times in each patient, and antegrade and retrograde specimens of those who ejac...

The wolf spider, Schizocosa ocreata (Hentz), varies foraging patch residence time in the presence of different sensory cues from prey, even without food rewards. This study examines the influence and interaction of hunger state, age and sex on the use of different types of sensory information to determine foraging patch sampling duration. In a series of two-chambered artificial foraging patches...

PURPOSE In prior work, a manually derived measure of vocal fold vibratory phase asymmetry correlated to varying degrees with visual judgments made from laryngeal high-speed videoendoscopy (HSV) recordings. This investigation extended this work by establishing an automated HSV-based framework to quantify 3 categories of vocal fold vibratory asymmetry. METHOD HSV-based analysis provided for cyc...

Introduction Four generic types of construction robots have been suggested in [4]. They were an assembling robot, an interior finishing robot, an exterior wall finishing robot, and a horizontal floor finishing robot. The interior finishing robot, as explained there, was designated to execute various interior finishing operations, such as partition erection, painting, plastering, jointing, tapin...
