Stratigraphic Architecture Of Shallow-Marine To Coastal-Plain Parasequences: Lower Williams Fork Formation, Southeastern Piceance Basin, Colorado, Rachel Victoria Shaak 2010 University of Colorado at Boulder

Stratigraphic Architecture Of Shallow-Marine To Coastal-Plain Parasequences: Lower Williams Fork Formation, Southeastern Piceance Basin, Colorado, Rachel Victoria Shaak

Geological Sciences Graduate Theses & Dissertations

The lower Williams Fork Formation in the southeastern Piceance Basin represents a transition from coastal-plain to shallow-marine environments of deposition. The stratigraphic architecture of the lower Williams Fork Formation was assessed by defining facies and facies associations in cores and outcrop exposures and then developing relationships between these facies and subsurface well-log signatures. The lower Williams Fork lies stratigraphically above the Rollins Sandstone Member of the Iles Formation and consists of several coal zones, two marine sandstone units informally named the middle and upper sandstones, and coastal-plain to alluvial-plain deposits. Parasequences were identified and correlated in the subsurface to characterize ...


The Synthesis Of Unnatural Morphine Derivatives As Glial Activation Inhibitors And The Synthesis Of Corticosterone-Glucuronide, Morin Mae Frick 2010 University of Colorado Boulder

The Synthesis Of Unnatural Morphine Derivatives As Glial Activation Inhibitors And The Synthesis Of Corticosterone-Glucuronide, Morin Mae Frick

Chemistry & Biochemistry Graduate Theses & Dissertations

A novel, non-neuronal mechanism to explain the development of opioid tolerance and dependance has been described. This mechanism involves the activation of spinal cord glia. Glia are important contributors to the creation of enhanced pain states via the release of neuroexcitatory and proinflammatory substances. Data suggest that glia also release neuroexcitatory substances in response to morphine, thereby opposing its effects. Inhibiting glial activation could therefore increase the clinical utility of analgesic drugs. The synthesis of advanced intermediates for the development of a series of novel morphinan-like structures that are potential glial activation inhibitors will be discussed.

Corticosterone displays an intense ...


Nmr Resonance Assignment Of The Therapeutic Rna Aptamer Macugen In Complex With Its In Vivo Target, The Heparin Binding Domain Of Vegf165, Andrew Eric Libby 2010 University of Colorado, Boulder

Nmr Resonance Assignment Of The Therapeutic Rna Aptamer Macugen In Complex With Its In Vivo Target, The Heparin Binding Domain Of Vegf165, Andrew Eric Libby

Chemistry & Biochemistry Graduate Theses & Dissertations

Aptamers consist of nucleic acids that are selected from an in vitro library in order to bind a specific target or catalyze a reaction. Many aptamer-ligand structures have been solved in recent years to characterize the molecular mechanisms that explain the high affinity and specificity observed in these interactions. To this end, NMR resonance assignment experiments were performed as a necessary first step to calculating the solution structure of a therapeutically-active RNA aptamer, Macugen, bound to its in vivo target, the heparin binding domain (HBD) of vascular endothelial growth factor 165 (VEGF165). Though the resonance assignment of Macugen is challenging ...


Thermal Desorption Metastable Atom Bombardment Ionization Aerosol Mass Spectrometer, Carly B. Robinson 2010 University of Colorado at Boulder

Thermal Desorption Metastable Atom Bombardment Ionization Aerosol Mass Spectrometer, Carly B. Robinson

Chemistry & Biochemistry Graduate Theses & Dissertations

A metastable atom bombardment (MAB) ionization source has been coupled to an existing thermal desorption aerosol mass spectrometer. The design allows real-time alternation between MAB and electron ionization (EI). A jet of metastable species produced in a DC discharge is directed at the ionization volume of the mass spectrometer, where Penning ionization is thought to be the dominant mechanism. Performance is characterized in experiments with oleic acid particles. By changing discharge gases between N2, Kr, and Ar, the excited state energy of the metastable species can be adjusted in the range 8.5-11.7eV. For vaporization at 180oC, all ...


Laboratory Studies Of Heterogeneous Chemistry, Brandon Michael Connelly 2010 University of Colorado at Boulder

Laboratory Studies Of Heterogeneous Chemistry, Brandon Michael Connelly

Chemistry & Biochemistry Graduate Theses & Dissertations

A high vacuum Knudsen flow reactor was used to determine the reactive uptake coefficient, γ, of isoprene on sulfuric acid films as a function of sulfuric acid weight percent, temperature, and relative humidity. No discernible dependence was observed for γ over the range of temperatures (220 − 265 K) and pressures (10−7 Torr -10−4 Torr) studied. However, the uptake coefficient increased with increased sulfuric acid concentration between the range of 78 wt % (γi 10−4) and 93 wt % (γi 10−3). In addition to the Knudsen Cell, a bulk study was conducted between 60 and 85 wt ...

Understanding the physical causes underlying solar spectral irradiance variations and the impact of these variations on terrestrial climate remain critical compelling challenges. On the solar side, the most fundamental unknown is the role of the “quiet-sun7 ,” a question brought into focus by spectral irradiance observations during the recent deep minimum, which show opposing trends in the infrared and ultraviolet portions of the spectrum (Harder et al. 2009). On the terrestrial side, while it is clear that the Sun played only a small role in late twentieth century warming, the signature of solar cycle variations in climate are now quite well ...


Reanalyses' Performance Of Boundary Layer, Cloud, And Surface Energy Budget Variables Over Arctic Pack Ice, Cassandra Renee Wheeler 2010 University of Colorado at Boulder

Reanalyses' Performance Of Boundary Layer, Cloud, And Surface Energy Budget Variables Over Arctic Pack Ice, Cassandra Renee Wheeler

Atmospheric & Oceanic Sciences Graduate Theses & Dissertations

Earth's climate has been changing rapidly, particularly in the Arctic; however, the Arctic is poorly understood due to spatially and temporally sparse observations. Arctic conditions prove difficult to obtain good quality, long-duration field measurements. Current studies utilize model-observation hybrid datasets (i.e., reanalyses); hence, the accuracy of processes represented in these datasets is important. In this study, meteorological parameters, turbulent fluxes, cloud properties, radiative fluxes, and the surface energy budget from ERA-40, ERA-Interim, NCEP/DOE, and JRA-25 reanalyses are compared to SHEBA observations. Six-hourly reanalyses data were interpolated to the location of the multiyear ice floe and combined, along ...


Measurements Of Oh Reactivity Using A Chemical Ionization Mass Spectrometry Technique, Joshua McGrath 2010 University of Colorado, Boulder

Measurements Of Oh Reactivity Using A Chemical Ionization Mass Spectrometry Technique, Joshua Mcgrath

Atmospheric & Oceanic Sciences Graduate Theses & Dissertations

Typically tropospheric chemical models overestimate [OH] when compared to measurements. This discrepancy is usually attributed to incompletely modeling OH sinks due to a lack of measurements. The determination of OH reactivity provides an independent means to quantify the overall contribution of these unmeasured trace species to OH oxidation. Therefore, a new instrument was developed to measure the total loss rate of OH to chemical species in ambient air using the CIMS technique.

Measurements were performed as part of two field campaigns, the Nucleation in Forests (NIFTy) study in Indiana during May 2008 and the Ocean-Atmosphere-Sea Ice- Snowpack (OASIS) Spring 2009 ...


Multiscale Landform Characterization For Land Use Evaluation Using Fuzzy Sets, Andrew R. Bock 2010 University of Colorado at Boulder

Multiscale Landform Characterization For Land Use Evaluation Using Fuzzy Sets, Andrew R. Bock

Geography Graduate Theses & Dissertations

A multi-scale geomorphometric landform model was created through the use of fuzzy semantic import models and fuzzy overlay to measure distribution of landforms within parcels of the Conservation Reserve Program in a portion of the Delaware River Sub-basin in Northeast Kansas. Different fuzzy logic operators (intersect, algebraic mean, and fuzzy gamma) were used to test the impact of different model mechanisms on the resulting distributions of crisp and fuzzy membership values, and classification uncertainty measured by entropy values. Across scales (900 m2 to 16,900 m2 window sizes), only one crisp class (drainages) showed an optimal scale for detection area ...


Data For Modelers--Helping Understand The Climate System, Mark A. Parsons 2010 University of Colorado at Boulder

Data For Modelers--Helping Understand The Climate System, Mark A. Parsons

Geography Graduate Theses & Dissertations

The Arctic is changing rapidly with dramatic local and global effect. To understand that change requires understanding the Arctic as a system. Models of different processes and at various scales are necessary tools for analyzing and understanding the Arctic system. Models are extremely diverse, yet they all require quality data. Through a series of case studies, augmented with ethnographic observation around the International Polar Year, this thesis examines how modelers assess, acquire, and prepare data for their models. By comparing specific case studies, common themes emerge that can be compared against broader observation. These themes, in turn, suggest data management ...


The Effect Of Learning Styles Strategies On Benchmark Eighth Grade Middle School Mathematics Achievement, Jean Ferrara 2010 Walden University

The Effect Of Learning Styles Strategies On Benchmark Eighth Grade Middle School Mathematics Achievement, Jean Ferrara

Walden Dissertations and Doctoral Studies

Low standardized mathematics scores resulted in a suburban middle school not reaching adequate yearly progress (AYP) for the 2 previous years. There were many possible factors contributing to this problem, among them the design of instruction. The purpose of this study was to identify learning styles of students and implement differentiated instructional strategies that address the learners' needs. The study was based on the Silver and Hanson's theory of learning style instruction and Gardner's multiple intelligences as a model for differentiating instruction. This sequential mixed methods quasi-experimental causal comparative design study investigated the effect of classroom intervention based ...

Anthropology Faculty Publications and Presentations

The article focuses on the historical ecology of the Pacific herring, a marine food web resource, in the Gulf of Alaska. It states the hearing conducted by the Alaska Legislature's House special committee on fisheries on the status and management of herring in Southeast Alaska during which Tlingit fisherman Clarence Jackson of Kake notes the disappearance of herring in his lifetime. Information on herring ecology based from Native and non-Native individuals from Southeast communities and archaeological site reports reveal that non-Natives in Southeast Alaska have exploited herring with the development of a herring reduction plant. It underscores the need ...


Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler 2010 Western Washington University

Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in ...

Geology Faculty Research and Scholarship

NASA's Phoenix Lander uncovered two types of ice at its 2008 landing site on the northern plains of Mars: a brighter, slab-like ice that broke during Robotic Arm operations; and a darker icy deposit. Spectra from the Phoenix Surface Stereo Imager (SSI) are used to demonstrate that the brighter material consists of nearly pure water ice, which probably formed by migration and freezing of liquid water. The darker icy material consists of similar to 30 +/- 20 wt% ice, with the remainder composed of fine-grained soil, indicating that it probably formed as pore ice. These two types of ice represent ...

The condensation, evolution, and sublimation of seasonal water and carbon dioxide ices were characterized at the Mars Phoenix landing site from Martian northern midsummer to midspring (Ls ∼ 142° – Ls ∼ 60°) for the year prior to the Phoenix landing on 25 May 2008. Ice relative abundances and grain sizes were estimated using data from the Compact Reconnaissance Imaging Spectrometer for Mars and High Resolution Imaging Science Experiment aboard Mars Reconnaissance Orbiter and a nonlinear mixing model. Water ice first appeared at the Phoenix landing site during the afternoon in late summer (Ls ∼ 167°) as an optically thin layer ...

Seasonal Ice Cycle At The Mars Phoenix Landing Site: 2. Postlanding Crism And Ground Observations, Selby Cull, R. E. Arvidson, R. V. Morris, M. Wolff, M. T. Mellon, M. T. Lemmon

Geology Faculty Research and Scholarship

The combination of ground observations from the Mars Phoenix Lander and orbital data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) provided a detailed view of the formation of late summer surface water ice at the landing site and surrounding regions. CRISM observations of the landing site during and immediately after Phoenix operations were analyzed to track the seasonal and diurnal ice cycles during the late spring to late summer, and a nonlinear mixing model was used to estimate grain sizes and relative abundances of water ice and dust. The surface around the Phoenix landing site was ice-free from ...

Monitoring the status and trends of our natural resources is the only way we can assess whether the actions that have been implemented are making a difference. The impetus for this resource condition monitoring program (RCM) was the recognition that our monitoring networks, baseline data and data management systems were inadequate to enable quantitative reporting to government, and the community, on the difference their investments in natural resource management were making. It was considered that making a significant investment in raising our ability to report would be a long-lasting legacy of value to the state.

An important concern when developing new inks containing novel, bulk, solid-state additives is to ensure consistency during the printing process. In particular, the additives should not build up on the rollers, blankets or plates during printing. In this work we describe a method for detecting such events and quantitatively monitoring, in real time, the consistency of developmental inks during commercial printing processes. The technique employs a two-component mixture of emissive nanoparticles whose ratio becomes variable in a non-homogeneous environment. Even tiny variations in the ratio can be readily and dynamically detected in real time using a fibre-optic equipped fluorescence microspectrometer ...
