Adequate Ventilation: How Is It Defined And Does It Adequately Warn Consumers?, Christopher Blankenship Jan 2013

Adequate Ventilation: How Is It Defined And Does It Adequately Warn Consumers?, Christopher Blankenship

Theses, Dissertations and Capstones

The purpose of this research was to clarify and define the term “adequate ventilation.” Upon looking at regulations, court cases, and other elements, it is clear that the term is inadequate to inform consumers and does not instruct consumers on how to achieve proper ventilation. To find out if consumers understand this, random persons were asked to define it. The answers were given a numerical value to show the knowledge trend. The outcome showed that most people do not understand how to achieve proper ventilation. Conclusion: Diagrams showing how to set up a room with ventilation and new instructions are …


Aging Effect On Foot Dynamics During Unexpected Slips, Jian Liu, Thurmon E. Lockhart Jan 2013

Aging Effect On Foot Dynamics During Unexpected Slips, Jian Liu, Thurmon E. Lockhart

Computer Sciences and Electrical Engineering Faculty Research

Slip-induced fall accidents have been recognized as a serious threat to the health of the elderly.The objective of the current study was to investigate the aging effect on the biomechanical reactions of both perturbed foot and unperturbed foot to the unexpected slips. Nineteen younger (mean age: 25.0 years old) and twenty-one older (mean age: 71.2 years old) adults were involved in a laboratory study,in which slippery surface was induced during walking without their awareness.The reactive responses of both slipping foot and unperturbed foot were quantified by optical motion capture system and force platforms.The results indicate a characteristic toe-touch strategy by …


Experimental Comparison Study Of The Response Of Polycarbonate And Laminated Glass Blast Resistant Glazing Systems To Blast Loading, Joshua Calnan Jan 2013

Experimental Comparison Study Of The Response Of Polycarbonate And Laminated Glass Blast Resistant Glazing Systems To Blast Loading, Joshua Calnan

Theses and Dissertations--Mining Engineering

This thesis recounts the experimental study of the dynamic response of polycarbonate blast resistant glazing systems to explosive loading through the use of triaxial load cells, pressure sensors, and a laser displacement gauge. This instrumentation captured the response of the glazing systems to blast loading over three phases of testing. The first phase of testing characterizes the load distribution around the perimeter and the second phase examines the repeatability of the results. The final phase of testing pushes the samples to failure. The results are then compared to HazL, a commonly used blast resistant glazing system analysis software tool. The …


Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman Jan 2013

Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman

All Master's Theses

The importance of cultural resource preservation cannot be overstated; however local economies are at least as important. Due to conservative archaeological site protection practices in Region 5 of the United States Forest Service, the economy of Northeastern California is being adversely affected. In an attempt to help the Forest Service make more informed management decisions and improve the Northeastern California economy, I undertook experiments on the effects of timber harvesting on lithic scatters on Modoc National Forest. The experiments involved placement of 225 glass tiles (proxy lithics) in each of three plots subject to vehicle traffic and log dragging by …
