Thermal And Mechanical Response Of Particulate Composite Plates Under Inertial Excitation, Jacob K. Miller, Daniel C. Wood, Jeffrey F. Rhoads

Purdue Energetics Research Center Articles

The thermal and mechanical, near-resonant responses of particulate composite plates formed from hydroxyl-terminated polybutadiene (HTPB) binder and varying volume ratios of ammonium chloride (NH4Cl) particles (50, 65, 75%) are investigated. Each test specimen is clamped and forced with three levels of band-limited, white noise inertial excitation (10–1000 Hz at 1.00, 1.86 and 2.44 g RMS). The mechanical response of each plate is recorded via scanning laser Doppler vibrometry. The plates are then excited at a single resonant frequency and the thermal response is recorded via infrared thermography. Comparisons are made between the mechanical operational deflection shapes of each plate and …

Misalignments: Challenges In Cultivating Science Faculty With Education Specialties In Your Department, Seth D. Bush, Nancy Pelaez, James A. Rudd Ii, Michael T. Stevens, Kimberly D. Tanner, Kathy S. Williams

PIBERG Publications

Science Faculty with Education Specialties (SFES) are increasingly being hired across the United States. However, little is known about the motivations for SFES hiring or the potential or actual impact of SFES. In the context of a recent national survey of US SFES, we investigated SFES perceptions about these issues. Strikingly, perceptions about reasons for hiring SFES were poorly aligned with perceptions about potential and actual contributions reported by SFES themselves, and the advice they extended to beginning SFES was varied. While preparation of future teachers and departmental teaching needs were common reasons offered for SFES hiring, the potential and …

Computational Investigation Of Microperforated Materials: End Corrections, Thermal Effects And Fluid-Structure Interaction, J Stuart Bolton, Nicholas Kim, Thomas Herdtle

Publications of the Ray W. Herrick Laboratories

The concept of microperforated noise control treatments was introduced by Maa 1975; in that theory, the transfer impedance of the microperforated layer was calculated based on oscillatory viscous flow within a small cylinder combined with resistive and reactive end corrections. Initially, microperforated materials were the subject of mostly academic study since practical implementations were rare owing to the cost of manufacturing the materials with acceptable accuracy. However, recently, new manufacturing procedures have dramatically lowered the cost of these materials, and perhaps as a result, there has been renewed interest in studying their properties. Since 1975, Maa’s original theory has been …

Enhancement Of The Low Frequency Performance Of Thin, Film-Faced Layers Of Foam By Surface Segmentation, J Stuart Bolton, Benoit Nennig, Nicolas Dauchez

Publications of the Ray W. Herrick Laboratories

While the control of high frequency noise by the use of porous treatments is relatively straightforward, it is correspondingly difficult to control low frequency noise owing to the general requirement that a porous layer should be a significant fraction of a wavelength in depth. Thus, it is of interest to develop low frequency sound absorbing treatments that are relatively compact by the use of surface treatments. Here, we illustrate an approach, in which a surface film is cut, to allow the incident sound to communicate directly with the air within the foam behind the film facing.

The present work was …

Libraries In Battle: An Analysis Of The Image Of The Library In Texts By Swift, Borges, And Sloan, Elyssa M. Gould

All NMU Master's Theses

This essay examines the image of the library in texts by Jonathan Swift, Jorge Luis Borges, and Robin Sloan. Libraries are prevalent institutions in many cultures throughout the world, often known through positive or negative stereotypes. By studying texts whose time periods, subject matter, and genre all differ, an image of the library appears that takes into account both positive and negative aspects to create a holistic image. The methods used to evaluate the texts include close reading, Frye’s archetypal theory, and approaches to the semiotic method championed by both Tancheva and Stelmakh. This study found that each story reveals …

Dissertations

The current obesity rates of our nation’s youth continue to escalate at an alarming rate due to inactivity, poor nutrition, and lifestyle changes. The purpose of this research study was conducted to determine the effects of Missouri Senate Bill 291 on Missouri physical fitness scores as assessed by the Missouri Physical Fitness Assessment. The state of Missouri adopted new physical activity requirements starting in the 2010-2011 school year. This study evaluated the impact of Missouri Senate Bill 291 on fifth and ninth grade physical fitness assessments. Eleven years of statewide data, were examined to determine the impact of the physical …

Fabrication And Characterization Of Antioxidant Loaded Liposomes., Brian Gettler

Electronic Theses and Dissertations

Radiation exposure is both a major obstacle in space exploration and an occupational hazard for various careers causing DNA damage and ROS. In order to reduce the effects of radiation, the primary and most explored approach has been focused around mitigation in terms of exposure duration, exposure intensity, and shielding usage. In some situations none of these reduction strategies were viable and so the use of antioxidants is being explored as an alternate strategy for therapeutic purposes. One such antioxidant is curcumin, otherwise known as diferuloylmethane, is a component of turmeric with both antioxidant properties and anti-inflammatory properties. Another antioxidant …

Fabrication Of A Thin Silver Nanowire Composite Film And Investigation Of A Patterning Technique., Richard S. Korte 1991-

Electronic Theses and Dissertations

Electrically conductive polymers encompass an exciting field of research for applications in dye-sensitized solar cells (DSSC’s). DSSC’s possess several advantages over other types of solar cells. They offer the potential for high quantum efficiency, solar conversion efficiency approaching that of traditional silicon panels, rapid charge transfer kinetics for photo-excited electrons, mechanical flexibility, and cost efficient manufacturing processes. However, key drawbacks to their large scale production and performance lifetime lie in their reliance on costly indium tin oxide (ITO), fluorinated tin oxide (FTO), and platinum for electrode materials, and the mechanical fragility inherent to a liquid electrolyte layer component. Much of …

A Social–Ecological Systems Approach To Non-Native Species: Habituation And Its Effect On Management Of Coqui Frogs In Hawaii, Emily A. Kalnicky, Mark W. Brunson, Karen H. Beard

Wildland Resources Faculty Publications

Non-native species introductions have the ability to affect both ecological and social systems, thus to address those outcomes both ecological and social influences on an invasion need to be understood. We use a social–ecological systems approach to investigate connections between human and ecological factors that affect efforts to control the non-native coqui frog (Eleutherodactylus coqui) on the island of Hawaii. The coqui frog is recognized as a ‘pest’ and ‘injurious wildlife’ by the Hawaii Department of Agriculture. Because the coqui occurs on many small private properties across the island, it is necessary to enlist private citizens in control efforts. Control …

Ecocriticism And National Image In 舌尖上的中国 (A Bite Of China), Mingwen Xiao

CLCWeb: Comparative Literature and Culture

In his article "Ecocriticism and National Image in 舌尖上的中国 (A Bite of China)" Mingwen Xiao examines the multi-faceted contents of the popular 2012 television series. Instead of exhibiting delicacies made by professional chefs in luxury restaurants, A Bite of China displays local food and dishes made by ordinary people. By focus on every-day food preparation, the show constructs a performance where class, ethnicity, gender, age, and other social markers are blurred and the geographically and ethnically diverse ways of food preparation and consumption appear as a cohesive Chinese culinary identity. Xiao argues that A Bite of China plays a role …

The Urgency Of Ecocriticism And European Scholarship, Simon C. Estok

CLCWeb: Comparative Literature and Culture

In his article "The Urgency of Ecocriticism and European Scholarship" Simon C. Estok argues that there continues to be unduly disproportionate attention within ecocriticism on US-based scholarship and proportionally less on ecocriticism from other parts of the world. Estok focuses on European ecocritical work written in English and published by Rodopi in recent years and argues that this work attests both to the urgency and resolve of European ecocritics. Estok looks at some of the primary contributions of twelve books published within the past ten years by Rodopi in order to show the importance of bending our ecocritical ears, to …

Ecocriticism And Persian And Greek Myths About The Origin Of Fire, Massih Zekavat

CLCWeb: Comparative Literature and Culture

In his article "Ecocriticism and Persian and Greek Myths about the Origin of Fire" Massih Zekavat argues that some contemporary ecological biases are rooted in ancient thought. Further, Zekavat argues that the study of mythology is relevant to the understanding of culture and ecology thus assisting ecocriticism. The investigation of man/woman, culture/nature, and human/nature binary oppositions conveys that Greek and Persian myths are mostly anthropocentric and androcentric. Zekavat postulates that one way to revise contemporary ecological conceptions is to study myths to shed light on the mind and context of their creators and believers, their representation of natural phenomena, and …
