Multi-Modality Magnetic Resonance Imaging In Typical And Atypical Developmental Human Brain, Minhui Ouyang

Bioengineering Dissertations - Archive

Human brain development is structurally and functionally a nonlinear process and even with the tremendous advancements in the field of neuroimaging based on Magnetic Resonance Imaging (MRI) several significant questions remain un-answered. Although brain change and adaption are part of a lifelong process, the earliest phases of maturation, especially from birth to early childhood, are perhaps the most dramatic and important. During this early developmental period, the structural and functional organization of the brain are continuously shaped by a combination of synaptogenesis, dendritic arborization, myelination and synaptic pruning. The current research aims to use more recently developed MRI techniques of …

Residual Effects Of Nitrogen Fertilization On Soil Nitrogen Pools And Corn Growth, Meghan E. Moser

Open Access Theses

Given the dynamic nature of soil nitrogen (N), inorganic N fertilization to corn (Zea mays L.) has potential to alter N pool balance by creating an accumulation or depletion of soil N. Current corn N recommendations in the common corn-soybean rotation of Indiana strive to find the best N rate that maximizes producer profit. Increasing our understanding of soil N will inform producers if they should adjust fertilizer rates for corn to influence maintenance of organic N and Carbon. Our objective was to determine residual N effects from fertilized corn in a corn-soybean rotation by measuring (1) soil N …

This thesis aims to investigate the feasibility of using sensor data from mote based light sensors tied to a BIM model, to be used for maintenance based facility management. More specifically, a prototype will be developed that integrates lighting sensor data collected using a mote …

Trajectory Optimization Using Indirect Methods And Parametric Scramjet Cycle Analysis, Joseph Williams

Open Access Theses

This study investigates the solution of time sensitive regional strike trajectories for hypersonic missiles. This minimum time trajectory is suspected to be best performed by scramjet powered hypersonic missiles which creates strong coupled interaction between the flight dynamics and the performance of the engine. Comprehensive engine models are necessary to gain better insight into scramjet propulsion. Separately, robust and comprehensive trajectory analysis provides references for vehicles to fly along. However, additional observation and understanding is obtained by integrating the propulsion model inside the trajectory framework. Going beyond curve fitted thrusting models, an integrated scramjet cycle analysis offers rapid trade studies …

The World In The Screen: How The Mobile Device Symbolizes Technogenesis, Joel Mathew Morrow

English Theses - Archive

The smart phone, or mobile device, holds a preeminent role in a technologically advanced society. These devices allow for connection, productivity, and distraction, and in doing so create new anxieties and underscore old ones. By tracing the provenance of this artifact, we see how our relationship with mobile devices amplifies our relationship with technology as a whole. This thesis examines the development of the mobile device from the viewpoints of social constructivism and technogenesis to illustrate how our increasing intimacy with these devices is part of a long-standing pattern of co-evolution between humans and the technologies they create.

Simulation results from a flow and nitrate calibrated SWAT model show large differences in year-to-year nitrate loads, a strong seasonality, and clear variability patterns in monthly nitrate loads in the 3S outlet during the wet season. The annual total nitrate loading from the 3S Rivers account for approximately 30% of the …

More Than Target 6.3: A Systems Approach To Rethinking Sustainable Development Goals In A Resource-Scarce World, Qiong Zhang, Christine Prouty, Julie B. Zimmerman, James Mihelcic

Civil and Environmental Engineering Faculty Publications

The 2030 Agenda for Sustainable Development outlines 17 individual Sustainable Development Goals (SDGs) that guide the needs of practice for many professional disciplines around the world, including engineering, research, policy, and development. The SDGs represent commitments to reduce poverty, hunger, ill health, gender inequality, environmental degradation, and lack of access to clean water and sanitation. If a typical reductionist approach is employed to address and optimize individual goals, it may lead to a failure in technological, policy, or managerial development interventions through unintended consequences in other goals. This study uses a systems approach to understand the fundamental dynamics between the …

Brain Transcriptional Profiles Of Male Alternative Reproductive Tactics And Females In Bluegill Sunfish, Charlyn Partridge

Open Access Publishing Support Funded Articles

Bluegill sunfish (Lepomis macrochirus) are one of the classic systems for studying male alternative reproductive tactics (ARTs) in teleost fishes. In this species, there are two distinct life histories: parental and cuckolder, encompassing three reproductive tactics, parental, satellite, and sneaker. The parental life history is fixed, whereas individuals who enter the cuckolder life history transition from sneaker to satellite tactic as they grow. For this study, we used RNAseq to characterize the brain transcriptome of the three male tactics and females during spawning to identify gene ontology (GO) categories and potential candidate genes associated with each tactic. We …

Laying The Groundwork For A National Impact Investing Marketplace, Stephanie L. Gripne, Joanne Kelley, Kathy Merchant

The Foundation Review

The practice of impact investing is rapidly gaining momentum, but the level of activity among individual and institutional investors, including philanthropists and foundations, has barely penetrated projections of market potential.

The marketplace that should connect impact investors with investees or social ventures does not function effectively.

Developing cost-effective ways to engage new investors and break down barriers to investment is an essential part of growing the industry.

Developing cost-effective ways to “prime the pump” for social ventures to become investor-ready — through a capacity-building process that includes outreach, education, and technical assistance — is an essential part of growing the …

Like A Duck On Water: Chinese Academic Migrants In The U.S. And Their Suburban Weekend Chinese School, Jianping Xu

Dissertations - ALL

Current literature is scarce on the diverse experiences of hundreds of thousands of mainland Chinese who, since 1979, have come to the U.S. primarily for graduate study and mostly settled here afterwards in dispersed university or corporate jobs and suburban residences. After the Immigration Act of 1990, many of them have become visible experts in science and engineering. Yet their struggles as Chinese academic migrants simultaneously privileged by their educational backgrounds and disadvantaged by their outsider status in the U.S. often remain invisible. Possibly due to the myth of “model minority,” mainstream America has seen them as doing-well and well-behaving, …

Development Of Non-Enzymatic Glucose Sensor Using The Template Deposited Nickel Modified Ito Electrode, V Ganesh

Manipal Journal of Science and Technology

Glucose sensors attract a great deal of attention due to the practical medical needs and applications. In this paper, we propose a simple methodology to modify semiconductor substrate such as indium tin oxide (ITO) in order to develop a non-enzymatic sensor for glucose detection. The proposed strategy involves a chemical modification of ITO electrode through electrodeposition of nickel and further by using electrochemical potential cycling in alkaline medium. Electrodeposition of nickel is carried out using two different methods. One involves the usage of nickel sulphamate electroplating bath in the absence of any template and the other comprises using a hexagonal …

Studies On Settlement Characteristics Of Lithomargic Clay Stabilized With Cement, Purushotham G. Sarvade Dr

Manipal Journal of Science and Technology

The lithomargic clay (shedi soil) is the name given to the locally available silty sand, which is present in between weathered laterite and hard granite gneiss throughout the Konkan belt of Southern India. As long as this soil is confined and dry, there is no problem, but on the exposure in a cutting or when it is exposed to water, it loses its strength drastically. Hence, modification of this soil is necessary to reduce settlement and improve the bearing capacity. In the present investigation, Ordinary Portland cement was used as a stabilizer to improve the soil. The investigation revealed that …
