The Effects Of Bioinspired Infill Designs And Density On The Compressive Strength Of Parts Produced By Additive Manufacturing Via Fused Deposition Modeling, Joseph D. Long
All-Inclusive List of Electronic Theses and Dissertations
The current state of additive manufacturing (AM) is still primarily used for prototyping and modeling. However, with the increase in available materials and more advanced machines, AM is beginning to become a production process in which ready-to-ship products are being manufactured. This makes it all the more important to effectively and efficiently use the material in AM machines. One of the ways that material usage can be improved upon is more efficiently structuring the infill material that is used. This dissertation reports on the testing and statistical analysis of the compressive modulus of elasticity, the compressive proportional limit, and the …

Impacts Of Different Forest Tree-Harvest Methods On Diets And Populations Of Insectivorous Forest Bats, Megan K. Caylor
Impacts Of Different Forest Tree-Harvest Methods On Diets And Populations Of Insectivorous Forest Bats, Megan K. Caylor
All-Inclusive List of Electronic Theses and Dissertations
The Hardwood Ecosystem Experiment (HEE) in central Indiana presents an excellent opportunity to study species reactions to different forestry practices: clearcutting, shelterwood cutting, and single tree selections. This project focuses on the differences in the populations and diets of the various insectivorous bat species in the HEE management units. Bats studied were Myotis septentrionalis, Lasiurus borealis, Eptesicus fuscus, Perimyotis subflavus, Myotis sodalis, Myotis lucifugus, and Lasionycteris noctivagans. Since insectivorous bats do not simply eat whatever is available, and I hypothesize that the diets of these bats will not change despite their changing environment and changing populations. To test these ideas, …

The Status Of Crawfish Frogs (Lithobates Areolatus) In Indiana, And A Tool To Assess Populations, Nathan J. Engbrecht
All-Inclusive List of Electronic Theses and Dissertations
The conservation status of Crawfish Frogs (Lithobates areolatus) in Indiana has changed over the past several decades. Once described as being locally plentiful, declines led to the listing of Crawfish Frogs as a State Endangered Species in 1988. Several records for this species in Indiana are > 50 yrs old and have gone unconfirmed for several decades. However, recent surveys have confirmed the continued presence of Crawfish Frogs in parts of southern Indiana, redefining the perceived range of this species in the state. In an effort to increase survey efficiency in this species, I used automated recording systems and manual call …
Glacial/Interglacial Export Production In The Subantarctic South Pacific, Jessica Adamic
Glacial/Interglacial Export Production In The Subantarctic South Pacific, Jessica Adamic
All-Inclusive List of Electronic Theses and Dissertations
Atmospheric CO2 varied considerably in the past; however, the mechanisms that drive this variability are poorly understood. CO2 is linked to marine primary productivity through the biological carbon pump (BCP), leading to hypotheses that past increases in BCP efficiency in areas such as the Southern Ocean may have contributed to glacial CO2 drawdown (Sarmiento & Toggweiler, 1984). Productivity has varied considerably in the past, but the extent, timing, and impacts remain poorly understood. The Subantarctic South Pacific is an area of the ocean that is crucial to the understanding of both glacial climate and paleo-export productivity. Unfortunately, few studies have …
