Beating Modes in Protostellar Disks

Creator:: Varga, Attila V.
Abstract:: Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...

A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

Creator:: Howell, Meghan Z.
Abstract:: Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...

Electrical Transport Measurements Show Intrinsic Doping and Hysteresis in Graphene p-n Junction Devices

Creator:: Plunkett, Garrett R.
Abstract:: Understanding the electrical transport properties of graphene provides a basis for determining its future as a potential semiconducting device that can be used for the next generation of transistors and photodetectors. Graphene p-n junctions can also function as field effect transistors, and thus are a logical starting point for I-V...

Detrital Input and Removal Treatment (DIRT) Network Soil Analysis in the UMBS Michigan Field Site

Creator:: Bushyhead, Coryn N.
Abstract:: Soil contains approximately 75% of the carbon pool on land - three times more than the amount stored in living plants and animals (Schlesinger 1999). Therefore, soils play a major role in maintaining a balanced global carbon cycle. Models of the soil carbon ecosystem assume a strong relationship between organic...

The Design of an Electric-Driven Saw Mill

Creator:: Autzen, Thomas and Smith, N. T.
Abstract:: The electric motor has for an number of years occupied an important position in the operation of wood-working machinery, of moderate capacity, for example the planing mills, sash and door factories and many of the other similar wood working shops. However its adoption in the more trying field of saw...

VOC Emisions and Categorization in Axenic Growth Conditions by Phaeodactylum tricornutum

Creator:: Thompson, Douglas A.
Abstract:: Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...

Ovarian protein hormones as biomarkers of fertility in dairy cows – Is it an acceptable model to predict infertility in dairy breeds?

Creator:: Lopez, Ruben
Abstract:: Female dairy cattle are particularly prone to infertility/subfertility with pregnancy rates ranging as low as 27% to a high 40%. On average it takes more than one breeding/insemination event for dairy cattle to become pregnant. This results in a loss of the number of calves a female would have per...
