The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, 2018 Virginia Institute of Marine Science
The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen
Although both local processes (photosynthesis, respiration, grazing, and settling), and transport processes (advective transport and diffusive transport) significantly affect local phytoplankton dynamics, it is difficult to separate their contributions and to investigate the relative importance of each process to the local variability of phytoplankton biomass over different timescales. A method of using the transport rate is introduced to quantify the contribution of transport processes. By combining the time-varying transport rate and high-frequency observed chlorophyll a data, we can explicitly examine the impact of local and transport processes on phytoplankton biomass over a range of timescales from hourly to annually. For ...

S. Fred Prince, a botanical illustrator and amateur scientist, is a largely unknown artist whose work on the American landscape demonstrates his eligibility to be considered in the lineage of self-taught illustrator-naturalists such as Mark Catesby and Genevieve Jones. In this article, we present a survey of extant Prince materials identified at time of writing, describing their contents and physical characteristics. Beyond this survey and description, we also provide a biographical sketch and timeline of Prince's life.
Altering Oligomerization Of Epha2 Via Mutations In The Intracellular Domain, 2018 The University of Akron
Altering Oligomerization Of Epha2 Via Mutations In The Intracellular Domain, Ryan W. Lingerak
Honors Research Projects
Eph receptor tyrosine kinases (RTKs) are activated by membrane-bound ligands called ephrins. Eph RTKs are divided into two subclasses, each activated by a specific classes of the ligand ephrin. The overexpression of Eph receptors is correlated to cancer cell metastasis in several different types of cancers. Studies with the EphA2 extracellular domain (ECD) and ephrinA1 ligand have shown that upon binding of ephrin to the receptor, EphA2 undergoes increased oligomerization and activation. This indicates that oligomerization is intimately connected to kinase activity. High resolution crystal structures of the EphA2 ECD have revealed some details of these ligand bound oligomers, as ...
Potential For Climate Induced Methane Hydrate Dissociation, 2018 Pomona College
Potential For Climate Induced Methane Hydrate Dissociation, Graham Macwilliams
Pomona Senior Theses
Methane hydrates are frozen deposits of methane and water found in high pressure or low temperature sediments. When these deposits destabilize, large quantities of methane can be emitted into the atmosphere. This is significant to climate change because methane has 25 times more greenhouse gas potential than Carbon Dioxide. Worldwide, it is estimated there are between 2500 and 10000 gigatons of methane stored in hydrate deposits. This represents more carbon than all fossil fuels on Earth. It is estimated that between 200 and 2000 gigatons of methane are stored in hydrates in Arctic waters acutely vulnerable to greenhouse warming. Over ...
Economic Growth And Changes In Forested Areas In Southeast Asia: Is Environmental Kuznets Curve Still Relevant?, Lan Thi Ngoc Nguyen
Undergraduate Honors Theses
The environmental history of the twentieth century in Southeast Asia reveals tremendous loss of forested areas as a consequence of unprecedented economic transformations and unrestrained globalization. Featuring some of the world’s fastest-growing economies, Southeast Asia has been experiencing fundamental changes in its economic structure, sociopolitical institutions, and the rate of natural resources extraction and depletion, including deforestation. This study reexamines evidence of the (EKC) hypothesis in light of the deforestation the above region experienced over the period 1990-2013. We use the change in forest cover as an indicator for environmental degradation. A panel co-integration approach is invoked to investigate ...

The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, 2017 Dominican University of California
The Effects Of Continuous Insulin Pump Therapy On Glycemic Control In Pregnant Type 1 Diabetics, Kimberly Kelsey
Senior Theses and Capstone Projects
Type 1 Diabetics have various ways of managing their diabetes that have been studied for their effectiveness. Pregnancy in the Type 1 Diabetic has been understudied. It is known that Diabetics in general have poorer pregnancy outcomes because of poor glycemic control. This coupled with the fact that the body needs 3-4 times more insulin as pregnancy comes to an end makes managing blood glucose levels challenging for diabetics (Lowdermilk, 2016, p. 689). For the Type 1 Diabetic, there are two main ways to control diabetes: multiple daily injections using at least two type of insulin and continuous subcutaneous insulin ...
Plasma Fibroblast Growth Factor-21 Levels In Patients With Inborn Errors Of Metabolism, 2017 George Washington University
Plasma Fibroblast Growth Factor-21 Levels In Patients With Inborn Errors Of Metabolism, Brian Kirmse, Juan Cabrera-Luque, Omar Ayyub, Kristina Cusmano-Ozog, Kimberly A. Chapman, Marshall L. Summar
Pediatrics Faculty Publications
Fibroblast growth factor-21 (FGF21) levels are elevated in patients with primary mitochondrial disorders but have not been studied in patients with inborn errors of metabolism (IEM) known to have secondary mitochondrial dysfunction. We measured plasma FGF21 by ELISA in patients with and without IEM. FGF21 levels were higher in patients with IEM compared to without IEM (370 pg/dL vs. 0–65 pg/dL). Further study of FGF21 as a biomarker in IEM is warranted.

Most nuclear-encoded mitochondrial proteins traffic from the cytosol to mitochondria. Some of these proteins localize at mitochondria-associated membranes (MAM), where mitochondria are closely apposed with the endoplasmic reticulum (ER). We have previously shown that the human cytomegalovirus signal-anchored protein known as viral mitochondria-localized inhibitor of apoptosis (vMIA) traffics from the ER to mitochondria and clusters at the outer mitochondrial membrane (OMM). Here, we have examined the host pathways by which vMIA traffics from the ER to mitochondria and clusters at the OMM. By disruption of phosphofurin acidic cluster sorting protein 2 (PACS-2), mitofusins (Mfn1/2), and dynamin related protein 1 ...
Characterisation Of Cold Plasma Treated Beef And Dairy Lipids Using Spectroscopic And Chromatographic Methods, 2017 Dublin Institute of Technology
Characterisation Of Cold Plasma Treated Beef And Dairy Lipids Using Spectroscopic And Chromatographic Methods, Chaitanya Sarangapani, David Dorran, Julie Dunne, Paula Bourke, Patrick Cullen
The efficacy of cold plasma for inactivation of food-borne pathogens in foods is established. However, insights on cold plasma-food interactions in terms of quality effects, particularly for oils and fats, are sparse. This study evaluated plasma-induced lipid oxidation of model matrices, namely dairy and meat fats. Product characterisation was performed using FTIR, 1H NMR and chromatographic techniques. The oxidation of lipids by cold plasma followed the Criegee mechanism and typical oxidation products identified included ozonides, aldehydes (hexanal, pentenal, nonanal and nonenal) and carboxylic acids (9-oxononanoic acid, octanoic acid, nonanoic acid), along with hydroperoxides (9- and 13-hydroperoxy-octadecadienoylglycerol species). However, these ...

Building Academic/Practitioner Teams For Human Rights Projects: Examples, Lessons Learned, And Pitfalls To Avoid, Theresa Harris
The Social Practice of Human Rights: Charting the Frontiers of Research and Advocacy
Academics are increasingly interested in getting out of their classrooms and labs to contribute their knowledge, expertise, and resources to help communities develop evidence-based policies. In addition to post-election initiatives such as the March for Science and 314 Action, many academics are joining “without borders”-type programs and organizations that connect academics with opportunities to volunteer their time and talents for “social good.”
One of the longest-running of these is On-call Scientists, an initiative of the American Association for the Advancement of Science (AAAS) that connects human rights organizations with pro bono scientists across all fields — life, physical, behavioral, and ...
Organismal Composition And Photosynthetic Traits Of Biological Soil Crusts In Prairie Ecosystems Of The Great Plains, 2017 Fort Hays State University
Organismal Composition And Photosynthetic Traits Of Biological Soil Crusts In Prairie Ecosystems Of The Great Plains, Brendon C. Mccampbell
Biological soil crusts (BSCs) are soil-surface microecosystems composed of a close association of algae, cyanobacteria, fungi, lichens, and non-vascular plants with soil particles. BSCs have several ecological functions including carbon fixation, nitrogen fixation, nutrient relations, soil stabilization, water relations, and floral community development, which make them extremely important in many of the ecosystems where they occur. While BSCs have been studied throughout the American West, little work has been done in the Great Plains region where they are less prominent among the dominant vascular plant communities. This study examined organismal composition and photosynthetic traits of BSCs in four ecosystems within ...
Astrovirus Infection In Hatchling Turkeys, 2017 Iowa State University
Astrovirus Infection In Hatchling Turkeys, Mari Thouvenelle, Joseph S. Haynes, Don L. Reynolds
Astrovirus is just one of several different enteric viruses identified in association with turkey viral enteritis, which has been a primary concern in the area of enteric diseases of turkeys, although the economic impact on the turkey industry is not fully known.1 Losses stem from the high morbidity of the disease resulting in decreased growth and flock unevenness. Additionally, this disease appears to be highly prevalent and geographically widespread. Astrovirus causes problems even for producers who employ good management practices in modem facilities.
Functional Analysis Of Drosophila Integrator Complex In Snrna 3' End Processing, 2017 The University of Texas Graduate School of Biomedical Sciences at Houston
Functional Analysis Of Drosophila Integrator Complex In Snrna 3' End Processing, Jiandong Chen
Uridine-rich small nuclear RNAs (U snRNAs) play essential roles in eukaryotic gene expression by facilitating the removal of introns from mRNA precursors and the processing of the replication-dependent histone pre-mRNAs. Formation of the 3’ end of these snRNAs is carried out by a poorly characterized, twelve-membered protein complex named Integrator Complex.
In the effort to understand Integrator Complex function in the formation of the snRNA 3’ end, we performed a functional RNAi screen in Drosophila S2 cells to identify protein factors required for snRNA 3’ end formation. This screen was conducted by using a fluorescence-based reporter that elicits GFP expression ...
