6/1/2007 - Conference papersThis paper discusses the application of digital human models to examine computer-generated forces necessary to move specific joysticks by using roof bolter virtual operators to predict the forces experienced on the operator's upper extremities.
-
10/1/2006 - Conference papersHand scaling is a physically demanding job responsible for overexertion injuries in mining. This experiment studied rib scaling from an elevated bucket to examine force generation capabilities and electromyographic responses to a prying subtask.
-
3/1/2006 - Peer reviewed journal articlesThirty-six human lumbar motion segments were fatigue tested using spinal compressive and shear loads that simulated lifting a 9 kg weight in three torso flexion angles. Results indicated that stellate endplate fractures were associated with increased po...
-
9/1/2005 - Conference papersThis paper compares the fatigue failure responses of older versus younger lumbar spine cadaver motion segment specimens.
-
1/1/2005 - Peer reviewed journal articlesThis study's objective was to simulate the postures and loads experienced by the lumbar spine during repetitive lifting of weights in different torso flexion postures, and to analyze the fatigue failure response of lumbosacral motion segments.
-
4/1/2002 - Peer reviewed journal articlesThis study evaluated spinal loads associated with lifting and hanging heavy mining cable in a variety of postures.
-
1/1/2001 - Conference papersObjectives: To determine the regional deposition of particulate matter in human lungs for a variety of steady-state engine operating conditions, fuel formulations and combinations of after treatment devices, and to characterize the size, distribution an...
-
10/1/1997 - Conference papersTwelve subjects participated in an investigation of the biomechanical stresses of asymmetric lifting in stooped and kneeling postures. Three factors were manipulated in this study: posture (stooped or kneeling), height of lift (35 or 70 cm), and weight ...
-
9/1/1997 - Book chaptersThe Bureau of Mines performed a pilot study examining the effects of posture on back strength and Maximum Acceptable Weight of Lift on six healthy male subjects (M = 32 years + 4 SD).
-
8/1/1997 - Peer reviewed journal articlesThe study was conducted to determine whether the kneeling posture alters extension torque capabilities in isometric and isokinetic exercises as compared with standing. A split-pilot experimental design was used to evaluate the influence of posture, tru...
