Biomechanics Of Slips In Alternative Footwear
… economic losses to occupational organizations. Slips, trips and an induced loss of balance have been identified as the major causative factor for workplace injuries involving falls (Courtney et al, 2001; Redfern et al, 2001). The bureau of labor statistics reported 15% of a total of 4,693 …

Effects of Occupational Exoskeletons on Responses to Simulated Slips and Trips
… use on reactive balance in response to simulated slips and trips. Five representative exoskeletons were investigated including leg-, back, and shoulder-support exoskeletons. This thesis consists of two studies: a smaller study investigating one exoskeleton and a larger one investigating multiple …

Effects of Quadriceps Fatigue on the Outcomes of Slips and Falls
Identifying potential risk factors that affect slip-induced falls is key to developing effective interventions for reduction of injuries caused by these accidents. Existing epidemiological evidence suggests that localized muscle fatigue might be considered as an intrinsic risk factor that causes …

How the soul slips in: Virginia Woolf's (un)natural history of dogs
Dogs have a crucial place in articulating ideas about class and sexuality in Woolf and her milieu. Her works move from considering dogs as representative instruments of class and gender in Mrs. Dalloway, to thinking more complexly about the dog/human boundary in Orlando. Human-to-animal ontologies …

Probing quantum phase slips in superconducting nanowires modified using high bias voltage pulses
Quantum phase slips (QPS) or the macroscopic quantum tunneling (MQT) of a nanowire’s order parameter through an activation energy barrier have remained the subject of intense debate for many years. They are expected to occur at low enough temperature where thermally activated phase slips (TAPS) …

The Effects of Age on Stress and The Biomechanics of Slips and Falls
… in reducing the occurrence of inadvertent slips and falls due to an increased awareness of one's external environment.

Aging effect on successful reactive-recovery from unexpected slips: a 3D lower extremity joint moment analysis
The objective of the proposed study was to perform three-dimensional (3D) inverse dynamics analysis to determine lower extremity (ankle, knee and hip) joint moments on previously collected slip perturbation experimental data. In addition, the aging effect on the joint moment generation in both …

Silent slips trips and broken hips: the recovery experiences of young adults following an isolated fracture of the proximal femur
Isolated hip fracture following a minor fall is a serious injury, normally requiring urgent surgical treatment and a complex recovery journey. Although commonly associated with the elderly, incidence and impact in adults under 60 years of age may be underestimated. The extensive literature almost …

Vibrating lubricant-infused porous surface for enhanced liquid droplet transport
Lubricant-infused porous surfaces (SLIPS) demonstrate extreme liquid repellency such that a droplet immiscible with the lubricant can roll off at a very small tilt angle < 5°. There have been many applications in using SLIPS to achieve complex fluids handling, anti-fouling, self-cleaning, …

Topological Excitations and Dissipation in Superconductors and Superfluids Having Multiply Connected Geometries
… discrete topological excitations, called phase-slips, in which vortex lines cross the superconducting or superfluid channel. The interaction between these excitations in multiply connected geometries are studied in various settings. Rich consequences are found to occur, including the sensitivity …

Switching Current Distributions of Superconducting Nanowires: Evidence of Quantum Phase Slip Events
Phase slips are topological fluctuation events that carry the superconducting order-parameter field between distinct current carrying states. Owing to these phase slips low-dimensional superconductors acquire electrical resistance. In quasi-one-dimensional nanowires it is well known that at higher …

Problems in GPS Accuracy
… methods for detecting and repairing cycle-slips in range delay data between a satellite and a receiver. The distance between a satellite and a receiver can be estimated by measuring the difference in the carrier frequency phase shift experienced between the satellite and receiver …

Identification and Modification of Risk Factors Contributing to Slip- and Trip-Induced Falls
Slips, trips, and falls are a serious public health concern, particularly among older adults and within occupational settings, given that falls contribute to a large number of injuries and associate with high medical costs. To reduce the number of falls, there is a need to better understand risk …

Effective Methods of Formative Assessment
… methods of formative assessment: daily exit slips and unit probing (pre-, middle-, and post-testing). While the data collected through research indicated that the use of unit probing showed more growth over the span of a unit than the use of daily exit slips, the study does not allow …

Age-Related Ankle Strength Degradation and Effects on Slip-Induced Falls
… influencing the initial phase of unexpected slips and falls in younger and older individuals. More specifically, the relationship between ankle strength, the ankle joint power to transfer the whole body center-of-mass during normal gait, and the likelihood of slip-induced falls was …

Action Intentions and the Puzzle of Non-Willed Behaviour
