A series of community-led, large-scale laboratory experiments, termed “StreamLab”, were performed by the National Center for Earth-surface Dynamics (NCED) with the purpose of advancing multidisciplinary research, education, and knowledge transfer at the interface of physical/chemical/biological processes in streams, science-based stream restoration practice, and environmental sensing technologies. Two series of experiments, StreamLab06 and StreamLab08, were conducted in the Main Channel of the St. Anthony Falls Laboratory at the University of Minnesota, a flume 84 m long and 2.75 m wide with water fed by the Mississippi River at a rate of up to 8.5 m3/s. The purpose of this paper is …

Predicting Natural Base-Flow Stream Water Chemistry In The Western United States, J. R. Olson, Charles P. Hawkins, D. M. Carlisle

Watershed Sciences Faculty Publications

[1] Robust predictions of stream solute concentrations expected under natural (reference) conditions would help establish more realistic water quality standards and improve stream ecological assessments. Models predicting solute concentrations from environmental factors would also help identify the relative importance of different factors that influence water chemistry. Although data are available describing the major factors controlling water chemistry (i.e., geology, climate, atmospheric deposition, soils, vegetation, topography), geologic maps do not adequately convey how rocks vary in their chemical and physical properties. We addressed this issue by associating rock chemical and physical properties with geological map units to produce continuous maps of …

“Babies Aren’T Persons”: A Survey Of Delayed Personhood, David F. Lancy

Sociology, Social Work and Anthropology Faculty Publications

To better understand attachment from a cross-cultural and historical perspective, I have amassed over 200 cases from the ethnographic and archaeological records that reveal cultural models (D'Andrade and Strauss 1992) of infancy. The 200 cases represent all areas of the world, historical epochs from the Mesolithic to the present and all types of subsistence patterns (Appendix 1). The approach is inductive where cases with similar models of infancy are clustered into archetypes. My principal finding from this analysis is that, in the broadest overview, infants are, effectively, placed on probation and not immediately integrated into the society. Attachment failure is …

Understanding Precision Nitrogen Stress To Optimize The Growth And Lipid Content Tradeoff In Oleaginous Green Microalgae, Curtis Adams, Valerie Godfrey, Bruce Bugbee, Brad Wahlen, Lance Seefeldt

Plants, Soils, and Climate Faculty Publications

Nitrogen deficiency promotes lipid formation in many microalgae, but also limits growth and lipid productivity. In spite of numerous studies, there is poor understanding of the interactions of growth and lipid content, the time course of lipid accumulation and the magnitude of nitrogen deficiency required to stimulate lipid formation. These relationships were investigated in six species of oleaginous green algae, comparing high and low levels of deficiency. Nitrogen stress typically had disproportionate effects on growth and lipid content, with profound differences among species. Optimally balancing the tradeoffs required a wide range in nitrogen supply rate among species. Some species grew …

Functional Constraints And The Evolution Of Ttx-Resistance In Ttx-Bearing Salamanders, Angela Haslem

Undergraduate Research and Creative Opportunities (URCO) Grant Program

Tetrodotoxin (TTX) binds to voltage-gated sodium (NaV) channels, blocking the initiation of action potentials and the activity of nerve and muscle fibers. Some salamanders use TTX as an anti-predator defense. These salamanders are resistant to TTX because they express TTX-resistant NaV channels in their nerves and muscles. In vertebrates, NaV channels are encoded by a multi-gene family. Different members of this gene family possess different functional properties and are expressed in different neuromuscular tissues. Cardiac muscle and the cardiac muscle channel (NaV 1.5) of amphibians and many reptiles is TTX-sensitive while NaV 1.5 in mammals (and some reptiles) is TTX-resistant. …

Characterization Of A Novel Fusion Protein Of Ipab And Ipad Of Shigella And Its Potential As A Pan-Shigella Vaccine, F. J. Martinez-Becerra, X. Chen, Nicholas E. Dickenson, S. P. Choudhari, K. Harrison, J. D. Clements, W. D. Picking, L. L. Van De Verg, R. I. Walker, W. L. Picking

Chemistry and Biochemistry Faculty Publications

Shigellosis is an important disease in the developing world, where about 90 million people become infected with Shigella spp. each year. We previously demonstrated that the type three secretion apparatus (T3SA) proteins IpaB and IpaD are protective antigens in the mouse lethal pulmonary model. In order to simplify vaccine formulation and process development, we have evaluated a vaccine design that incorporates both of these previously tested Shigella antigens into a single polypeptide chain. To determine if this fusion protein (DB fusion) retains the antigenic and protective capacities of IpaB and IpaD, we immunized mice with the DB fusion and compared …

(A)Filiaciones Femeninas: Gorriti Y La Genealogía De La Escritura En Lima, Rocío Del Águila

Decimonónica

La presencia de varias mujeres escritoras a finales del siglo XIX en el Perú no es producto del azar, sino del esfuerzo de ciertos intelectuales en promover un discurso que admitiera esta posibilidad y en elevar a algunas figuras femeninas de las letras. Aunque en medio de una coyuntura política compleja, Lima se dio abasto para tener un ambiente intelectual activo en el que se discutían temas de actualidad a la par que se componían versos.1 En esta época, Juana Manuela Gorriti (Argentina, 1818-1892) regentó las veladas literarias en su hogar en el que participaron destacados personajes y que se …

2 People in the Water Planning Picture

People have always had an impact on how water interacts with the landscape, but social scientists have long been absent from water policy discussions and decisions. Sociologist Douglas Jackson-Smith and his colleagues are working to change that and to shape our water future.

8 Designing Where the Water Goes

Streets, sidewalks, rooftops and patios all affect what happens when the rain falls, and what happens to stormwater effects every community. The design of streets and other landscape elements has a big impact on this important part of the water cycle and can help …

The Magnitude And Mechanism Of Charge Enhancement Of Ch∙∙O H-Bonds, U. Adhikari, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

Quantum calculations find that neutral methylamines and thioethers form complexes, with N-methylacetamide (NMA) as proton acceptor, with binding energies of 2–5 kcal/mol. This interaction is magnified by a factor of 4–9, bringing the binding energy up to as much as 20 kcal/mol, when a CH3+ group is added to the proton donor. Complexes prefer trifurcated arrangements, wherein three separate methyl groups donate a proton to the O acceptor. Binding energies lessen when the systems are immersed in solvents of increasing polarity, but the ionic complexes retain their favored status even in water. The binding energy is reduced when the methyl …

Wolf Creek Ranch Aspen Monitoring Report, Paul C. Rogers, Allison Jones, James Catlin, James Shuler, Arthur Morris, Michael Kuhns

Aspen Bibliography

In the summer of 2012 we undertook a landscape assessment of aspen forest conditions at Wolf Creek Ranch (WCR) near Kamas, Utah. Using a geographic information system (GIS) coverage of predicted aspen coverage, fifty systematically selected field "plots" were located and mapped with aspen stands around WCR. Seven plots were eventually discarded from our survey due to lack of aspen cover. Volunteer field crews, mostly WCR homeowners, collected aspen data documenting tree sizes, height/age groups, diameters, reproduction, mortality, browse levels, and browse animal use levels.

Aspen Status Report And Recommendation For The Book Cliffs, Paul C. Rogers, Cody M. Mittanck, Ronald J. Ryel

Aspen Bibliography

Regionally quaking aspen (Populus tremuloides Michx.) forests are experiencing numerous impediments to resilience. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. We conducted a landscape assessment of aspen communities in the Book Cliffs region, Vernal Field Office of the Bureau of Land Management, for the purposes of determining landscape-level status of aspen and making recommendations for future management of these forests. The study area consists of 268 distinct aspen polygons totaling approximately 70 ha (174 acres) of aspen forest surrounded by much larger tracts of …
