Dynamic Models for Sideways Falls From Standing Height

Journal of Biomechanical Engineering, 1995
Despite our growing understanding of the importance of fall mechanics in the etiology of hip fracture, previous studies have largely ignored the kinematics and dynamics of falls from standing height. Beginning from basic principles, we estimated peak impact force on the greater trochanter in a sideways fall from standing height.

Spinal fractures incurred by a fall from standing height

Clinical Neurology and Neurosurgery, 2019
Falls from standing are common, particularly amongst the aging population, due to declining mobility, proprioception and vision. They are often complicated by fragility fractures, including vertebral fractures, that are associated with significant morbidity and may represent a pre-terminal condition with high one-year mortality rates.A retrospective ...

Forest Stand Height Estimation

2019
The measurement of forest structural characteristics is important for a variety of Monitoring, Reporting, and Verification (MRV) protocols in resource management.\r\nOne characteristic of particular importance is Forest Stand Height (FSH), or the average height of trees in a forest stand. In this context, FSH can be used an indicator\r\nof the age of a

Standing Height/Sitting Height Relationhip in Western Region in Kosovo

SSRN Electronic Journal, 2018
The purpose of this research is to examine standing height in both Kosovan genders in the Western Region as well as its association with sitting height, as an alternative to estimating standing height. A total of 664 individuals (338 male and 326 female) participated in this research. The anthropometric measurements were taken according to the protocol

Modelling dominant height growth: effect of stand density.

2003
In many timber species, height growth of dominant trees (100 largest trees per ha) in even-aged stands is usually assumed to remain unchanged over a wide range of stand density. This assumption allows us to use the stand dominant height (mean height of the 100 largest trees per ha) at a specified reference age as an index of site quality.

Standing Height/Sitting Height Ration in Eastern-Kosovan Adolescents

SSRN Electronic Journal, 2018
The purpose of this research is to examine standing height in both Kosovan genders in the Eastern Region as well as its association with sitting height, as an alternative to estimating standing height. A total of 364 individuals (185 male and 179 female) participated in this research. The anthropometric measurements were taken according to the protocol

Optical Remote Sensing of Tree and Stand Heights

Tree height and vegetation height distribution are structural characteristics of major importance when attempting to understand and monitor biological and ecological processes at tree, stand, and landscape scales. Tree height plays a central role in forest inventories, and height growth is a main driver for growth and yield models.

Electromyographic activity of the neck muscles: Effects of varying standing height-derived teaching board heights

Journal of Back and Musculoskeletal Rehabilitation, 2020
BACKGROUND: Despite the increasing emergence of modern facilities, the ancient practice of writing on a teaching board is still common in the teaching profession. Ergonomic guidelines of this practice are required for the prevention of work-related neck musculoskeletal disorders inherent of teachers.

Standing Stokes waves of maximum height

Journal of Fluid Mechanics, 1973
An analytic expression is found for an infinite subset of the coefficients of the perturbation expansion. They are the coefficients of the terms most rapidly varying at each order, which are also the first terms in the expansion of each Fourier coefficient. The sum of these terms gives a nonlinear approximation to the solution.
