Feasibility Study Of Biogas Generated Electricity For The Austin E. Knowlton Center For Equine Science At Otterbein University, Jillian Strimbu Apr 2016

Feasibility Study Of Biogas Generated Electricity For The Austin E. Knowlton Center For Equine Science At Otterbein University, Jillian Strimbu

Undergraduate Distinction Papers

Manure removal is an important issue for Otterbein University’s Austin E. Knowlton Center for Equine Science. Evaluating alternative methods for manure removal at Otterbein is essential for both economic and green energy initiatives. Two companies who manufacture waste to energy systems, SEaB Energy and Bioferm Energy Systems, were contacted regarding the feasibility for the small-scale anaerobic digesters that they currently market (the Muckbuster and EUCOlino, respectively). Quasar Energy Corporation was also contacted as a possible off-site manure disposal option at their Zanesville large-scale dry digestion facility. Both the Muckbuster and EUCOlino options were determined to be economically infeasible for Otterbein …

Distinct Components Of Retrograde Cav1.1-Ryr1 Coupling Revealed By A Lethal Mutation In Ryr1, David Sheridan Feb 2016

Distinct Components Of Retrograde Cav1.1-Ryr1 Coupling Revealed By A Lethal Mutation In Ryr1, David Sheridan

Biology and Earth Science Faculty Scholarship

The molecular basis for excitation-contraction coupling in skeletal muscle is generally thought to involve conformational coupling between the L-type voltage-gated Ca2+ channel (CaV1.1) and the type 1 ryanodine receptor (RyR1). This coupling is bidirectional; in addition to the orthograde signal from CaV1.1 to RyR1 that triggers Ca2+ release from the sarcoplasmic reticulum, retrograde signaling from RyR1 to CaV1.1 results in increased amplitude and slowed activation kinetics of macroscopic L-type Ca2+ current. Orthograde coupling was previously shown to be ablated by a glycine for glutamate substitution at RyR1 position 4242. In this study, we investigated whether the RyR1-E4242G mutation affects retrograde …


Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer Jan 2016

Resurgence Of Acropora Corals On Mid Shelf Patch Reefs, Southwater Caye Marine Reserve, Central Belize, Jillian J. Keefer

Undergraduate Honors Thesis Projects

Acropora cervicornis (staghorn) and Acropora palmata (elkhorn) are ecologically important corals that grow quickly and provide topography and refuges for fish and invertebrates. Historically, Acropora was the most abundant coral in shallow patch reef zones in the Caribbean. During the 1980s, white band disease eliminated most Acropora causing a loss in rugosity and an increase of macroalgae on many reefs. Although Acropora remains rare throughout most of the Caribbean, this study documents its partial comeback and possible limiting factors in Southwater Caye Marine Reserve (SWCMR), Central Belize. Patch reefs in the reserve averaged 19% live coral cover with A. palmata …


Determination Of Cyclic-Di-Gmp- Controlled Gene Expression In A Pharmacologically Important Bacterium, Morgan A. Stark Jan 2016

Determination Of Cyclic-Di-Gmp- Controlled Gene Expression In A Pharmacologically Important Bacterium, Morgan A. Stark

Undergraduate Honors Thesis Projects

The second messenger molecule cyclic dimeric GMP (c-di-GMP) regulates a myriad of processes in gram-negative bacteria. However, less is known about the roles it plays in gram-positive bacteria. Differential gene expression in three strains of the gram-positive bacterium, Streptomyces coelicolor, is being studied using RNA sequencing and Real Time PCR to gain insight into c-di-GMP signaling. The rmdA rmdB (regulator of morphology and development) double mutant was compared to the wild type strain known as MT1110. The rmdA and rmdB genes are needed for the formation of aerial mycelium, an important step in the life cycle of Streptomyces coelicolor (Hull …
