The Effects of Obesity and Age on Balance Recovery After Slipping
Falls due to slipping are a serious occupational concern. Slipping is estimated to cause 40-50% of all fall-related injuries. In 2011, falls resulted in 22% of injuries requiring days away from work. Epidemiological data indicates that older and obese adults experience more falls than young, …

Slipping into Sleep: neurodynamics of alertness transitions in humans and fruit flies
The ability to react to events in the external world determines the fate of every living organism, this general state of readiness is called as ’alertness’. What happens to neurodynamics in the brain when alertness fades away as we fall asleep? How is behaviour affected? These questions will help …

An Exploratory Study Investigating the Time Duration of Slip-Induced Changes in Gait
… Prior studies have shown changes in gait after slipping, and these changes can reduce the external validity of experimental results. As such, most researchers only slip participants one time. The ability to slip participants more than once, after allowing gait to return to a natural baseline, …

Identification and Modification of Risk Factors Contributing to Slip- and Trip-Induced Falls
… interventions to reduce risk of falls due to slipping and tripping. The first study investigated the effects of performing occupationally-relevant fatigue-inducing physical work on trip and fall risk. Healthy young adults performed a simulated manual material handling (MMH) task, using either …

Transform Faults, Fracture Zones, and the Kinematics of Horizontal Thermal Contraction of Oceanic Lithosphere
… pairs with both left-lateral and right-lateral slipping transform faults, azimuths are biased by about 0.75°±0.36° clockwise for left-lateral slipping and by −0.73°±0.22° (= ±1 standard error) counter-clockwise for the right-lateral slipping. I, then investigate if this observed bias can be …

Parsimonious item response theory modeling with different link functions
… the NLL model addresses the effects of slipping via an inflection point that is lower than in the Rasch or 2PL models. Importantly, unlike traditional IRT models that focus on guessing and slipping as response behaviors associated with the extreme levels of the latent trait, I show that …

Dynamics of an unbalanced ring spinning on a rough horizontal surface
… considered are the pure-rolling and rolling-with-slipping motions. Given favorable initial conditions, ring properties, and a sufficiently large constraint force in the form of friction, the ring undergoes a pure-rolling motion. For other conditions, however, limitations on the magnitude of the …

The Effect of Mental Fatigue on Risk of Falling
… on gait variables associated with the risk of slipping and tripping. The study also investigated the efficacy of a 10-minute rest break in mitigating the effect of mental fatigue on those variables. Twenty healthy young adults (10 males and 10 females) participated and completed two …

Study of the Effect of Interface Slip and Diffusion Mechanisms on the Creep of Metal and Intermetallic Matrix Composites
… interface is either perfectly bonded, freely slipping, or rapidly diffusive, the transient solution scales with the applied load and the matrix creep viscous modulus. The transient solutions at large times are found to approach the corresponding solutions obtained from the direct steady state …

“We Have to Record the Downfall of Tyranny”: The London Times Perspective on Napoleon Bonaparte’s Invasion of Russia
… how England feared its grip on Europe was slipping away due to a French takeover of the continent. This work details the English struggle in order to provide a broader analysis through a newspaper of how nations indirectly involved in the Napoleonic wars understood the conflict.</p>

The dynamics of oceanic transform faults : constraints from geophysical, geochemical, and geodynamical modeling
… Bouguer gravity anomalies are found within fast-slipping transform fault domains. These gravity observations suggest a mass deficit within fast-slipping transform faults, which may result from porosity variations, mantle serpentinization, and/or crustal thickness variations. Two-dimensional …

An evaluation of financial crisis in Thailand
… However by mid 1997, Thailand's economy was slipping into the so-called "Thailand financial crisis": falling property prices, slowing exports, rising trade deficits, and the devaluation of the Thai baht. This raises concern about the future. The purpose of this thesis is to examine Thai …

Generating grasping using models based on duality
… are large enough to keep the object from slipping. The objects considered are polyhedra and valid grip checks for both convex and concave objects are developed. A generate and test method for synthesizing valid grasp positions is also presented.

Being Alone: The Experience of Elderly Homebound Females
… Five main themes emerged from the data: slipping away, balancing dependence and independence, making the most of it, connecting and looking inward. Portions of the women's lives were slipping away as they passed their life expectancy and were living on borrowed time. Contacts with friends …

Investigation of the Processing History during Additive Friction Stir Deposition using In-process Monitoring Techniques
… and tool head is characterized by a full slipping condition (δ=1). In this case, interfacial friction is the dominant heat generation mechanism and compression is the primary deformation mechanism. In Al-Mg-Si, the interfacial contact is characterized by a partial slipping/sticking …
