Td-Dft Calculations And Mcd Spectroscopy Of Porphyrin And Phthalocyanine Analogues: Rational Design Of Photosensitizers For Pdt And Nir Region Sensor Applications, John Mack, Martijn Wildervanck, Tebello Nyokong

Turkish Journal of Chemistry

Geometry optimizations and TD-DFT calculations have been carried out on series of fused-ring-expanded phthalonitriles, phthalocyanines, and aza-dipyrromethene boron difluoride (aza-BODIPY) dyes and trends in their optical and redox properties have been analyzed. The potential utility of fused-ring-expanded phthalocyanine and aza-BODIPY analogues for photodynamic therapy and near infrared region sensor applications is assessed on this basis. Recent attempts to prepare fused-ring-expanded aza-BODIPY analogues with benzene, pyrazine, and naphthalene rings have demonstrated that the properties of aza-BODIPYs vary markedly when different fused ring systems are added to the \beta-carbons of the pyrrole rings. A comparison of the TD-DFT calculations demonstrates that, as …

New Soluble Amidoamine Substituted Phthalocyanines: Synthesis, Characterization, And Investigation Of Their Solution Properties, Senem Çolak, Sali̇h Zeki̇ Yildiz

Turkish Journal of Chemistry

The synthesis of tetraaminopropylamid substituted phthalocyanines was targeted to prepare enhanced soluble phthalocyanines in common solvents from hydrophobic to hydrophilic that bore nonionic groups on their periphery. Metal-free (H_2Pc) and metallophthalocyanines (Zn(II) (ZnPc), Cu(II) (CuPc) and Co(II) (CoPc)) were prepared and characterized by UV-Vis, FT-IR, and mass spectroscopies. The ^1H NMR spectra were recorded for the diamagnetic phthalocyanine species H_2Pc and ZnPc. The phthalocyanines showed sufficient solubility in common organic solvents such as dimethyl sulfoxide, tetrahydrofuran, and ethanol. However, methanol was not a good solvent for CuPc and H_2Pc. Solubility and aggregation studies of H_2Pc and ZnPc were performed in …

Regional Distribution Shifts Help Explain Local Changes In Wintering Raptor Abundance: Implications For Interpreting Population Trends, Neil Paprocki, Julie A. Heath, Shawn J. Novak

Biology Faculty Publications and Presentations

Studies of multiple taxa across broad-scales suggest that species distributions are shifting poleward in response to global climate change. Recognizing the influence of distribution shifts on population indices will be an important part of interpreting trends within management units because current practice often assumes that changes in local populations reflect local habitat conditions. However, the individual- and population-level processes that drive distribution shifts may occur across a large, regional scale and have little to do with the habitats within the management unit. We examined the latitudinal center of abundance for the winter distributions of six western North America raptor species …

Murchison Chondrite, Marisol Chirinos

Natural Sciences Student Research Presentations

Murchson Chondrite is a carbonaceous meteorite that fell in a small town called Murchson in Victoria, Australia, on September 28, 1969. It is believed to be one of the most primitive meteorites to fall on earth. Amino acides found in Murchison differ in structures from amino acids found on Earth. While the carbon atom in the carboxylic acid and amion group of biological terrestrial amino acids have a hydrogen atom attached to it, the Murchison's amino acids have a methyl group instead.

Reflections On Deep Time: From The Big Bang To The End Of Planet Earth, Daniel E. Schafer

Belmont Humanities Symposium Journal

Historians are well-known students of time. As a professional historian, I study events that occurred roughly a century ago. While their interest in specific time periods may vary, all historians engage with the question of change over time. Historians traditionally limit themselves to the age of written records—the last several thousand years or so—though we are always happy to supplement our study of documents with statues, ruins, paintings, artifacts and other debris of the past. As we go back to earlier periods, we increasingly rely on our archeologist friends to supplement our study of written records. For the very earliest …

Introduction, Maggie P. Monteverde

Belmont Humanities Symposium Journal

The impetus for this year’s symposium “Worlds Enough and Time” began for me more than forty years ago, while I was working on my senior thesis on “Concepts of Order and Chaos in Anglo-Saxon Poetry” and happened to notice that the idea of time underlying one of the poems was quite different from my own. So, as I prepared to write this introduction, I found myself returning to the starting point of my interest: the Anglo-Saxons. Surely, I thought, one of their famous riddles must have as its answer, Time. Not that I could find. So I tried to write …

Generations Enough, And Time, John Niedzwiecki, Meg Streams

Belmont Humanities Symposium Journal

Since the Enlightenment, scientific inquiry has shown that the immensities of time and space humans have always sensed, worshipped, and feared are not immune to measurement. Despite the anxieties of a variety of “establishments” through the years, for many people, measurement and greater understanding has not stolen creation’s wonder, but rather increased it. Quantitative science gives us an ability to put numbers on extreme quantities, whether on the vast scale of interstellar or intergalactic distances, geological or cosmological time, or the micro-scale of tiny probabilities. Yet we have no natural intuition for such numbers. If we don’t make an effort …

Response Of Fusarium Thapsinum To Sorghum Brown Midrib Lines And To Phenolic Metabolites, Deanna L. Funnell-Harris, Scott E. Sattler, Jeffrey F. Pedersen

Department of Plant Pathology: Faculty Publications

Sorghum lines were bred for reduced lignin for cellulosic bioenergy uses, through the incorporation of brown midrib (bmr)6 or -12 into two backgrounds (RTx430 and Wheatland) as either single or doublemutant lines. When these lines were assessed for resistance to Fusarium thapsinum stalk rot, a cause of lodging, they were as resistant to F. thapsinum as the near-isogenic wild type. Peduncles of newly identified bmr lines from an ethyl-methanesulfonate-mutagenized population, inoculated with F. thapsinum, were as resistant as the wild-type line, BTx623. One bmr line (1107) had significantly smaller mean lesion lengths than BTx623, suggesting that a mutation …

Industrialism Vs Environmentalism, Isaiah Sun

Nebraska College Preparatory Academy: Senior Capstone Projects

This study is about the struggle in our society between industrialism and environmentalism. Environmentalists point out the industrialism is destroying the environment at a rapid pace. Industrialists believe that environmentalism would push businesses out of the country and therefore hurt the economy. Studies like this are important because in a developing world such as this we must know where we want to be and where we are right now.

The Amino Acid Composition Of The Sutter’S Mill Cm2 Carbonaceous Chondrite, Aaron Burton, Daniel Glavin, Jamie Elsila, Jason Dworkin, Peter Jenniskens, Qing-Zhu Yin

United States National Aeronautics and Space Administration: Publications

We determined the abundances and enantiomeric compositions of amino acids in Sutter’s Mill fragment #2 (designated SM2) recovered prior to heavy rains that fell April 25–26, 2012, and two other meteorite fragments, SM12 and SM51, that were recovered postrain. We also determined the abundance, enantiomeric, and isotopic compositions of amino acids in soil from the recovery site of fragment SM51. The three meteorite stones experienced terrestrial amino acid contamination, as evidenced by the low D/L ratios of several proteinogenic amino acids. The D/L ratios were higher in SM2 than in SM12 and SM51, consistent with rain introducing additional L-amino acid …

Label-Free Detection Of C-Reactive Protein Using A Carbon Nanofiber Based Biosensor, Rakesh K. Gupta, Adaikkappan Periyakaruppan, M. Meyyappan, Jessica E. Koehne

United States National Aeronautics and Space Administration: Publications

We report the sensitive detection of C-reactive protein (CRP), a biomarker for cardiac disease, using a carbon nanofiber based biosensor platform. Vertically aligned carbon nanofibers were grown using plasma enhanced chemical vapor deposition to fabricate nanoelectrode arrays in a 3 x 3 configuration. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (ElS) were used for the CRP detection. The CV responses show a 25% reduction in redox current upon the immobilization of anti-CRP on the electrode where as a 30% increase in charge transfer resistance is seen from EIS. Further reduction in redox current and increase in charge transfer resistance result …

Biological System Development For Gravisat: A New Platform For Studying Photosynthesis And Microalgae In Space, Erich D. Fleming, Vrad M. Bebout, Ming X. Tan, Florian Selch, Antonio J. Ricco

United States National Aeronautics and Space Administration: Publications

Microalgae have great potential to be used as part of a regenerative life support system and to facilitate in-situ resource utilization (ISRU) on long-duration human space missions. Little is currently known, however, about microalgal responses to the space environment over long (months) or even short (hours to days) time scales. We describe here the development of biological support subsystems for a prototype “3U” (i.e., three conjoined 10-cm cubes) nanosatellite, called GraviSat, designed to experimentally elucidate the effects of space microgravity and the radiation environment on microalgae and other microorganisms. The GraviSat project comprises the co-development of biological handling-and-support technologies with …

Antiproliferative Activity Of Novel Imidazopyridine Derivatives On Castration-Resistant Human Prostate Cancer Cells, Sakthivel Muniyan, Yu-Wei Chou, Matthew A. Ingersoll, Alexus Devine, Marisha Morris, Valerie A. Odero-Marah, Shafiq A. Khan, William G. Chaney, Xiu R. Bu, Ming-Fong Lin

United States National Aeronautics and Space Administration: Publications

Metastatic prostate cancer (mPCa) relapses after a short period of androgen deprivation therapy and becomes the castration-resistant prostate cancer (CR PCa); to which the treatment is limited. Hence, it is imperative to identify novel therapeutic agents towards this patient population. In the present study, antiproliferative activities of novel imidazopyridines were compared. Among three derivatives, PHE, AMD and AMN, examined, AMD showed the highest inhibitory activity on LNCaP C-81 cell proliferation, following dose- and time-dependent manner. Additionally, AMD exhibited significant antiproliferative effect against a panel of PCa cells, but not normal prostate epithelial cells. Further, when compared to AMD, its derivative …

Temporal Ecology In The Anthropocene, E. M. Wolkovich, B. I. Cook, K. K. Mclauchlan, T. J. Davies

United States National Aeronautics and Space Administration: Publications

Two fundamental axes – space and time – shape ecological systems. Over the last 30 years spatial ecology has developed as an integrative, multidisciplinary science that has improved our understanding of the ecological consequences of habitat fragmentation and loss. We argue that accelerating climate change – the effective manipulation of time by humans – has generated a current need to build an equivalent framework for temporal ecology. Climate change has at once pressed ecologists to understand and predict ecological dynamics in non-stationary environments, while also challenged fundamental assumptions of many concepts, models and approaches. However, similarities between space and time, …

Angler Effort And Catch Within A Spatially Complex System Of Small Lakes, Christopher J. Chizinski, Dustin R. Martin, Kevin L. Pope, Tony J. Barada, Jeffrey J. Schuckman

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Spatial layout of waterbodies and waterbody size can affect a creel clerk’s ability to intercept anglers for interviews and to accurately count anglers, which will affect the accuracy and precision of estimates of effort and catch. This study aimed to quantify angling effort and catch across a spatially complex system of19 small (<100 ha) lakes, the Fremont lakes. Total (±SE) angling effort (hours) on individual lakes ranged from 0 (0) to 7,137 (305). Bank anglers utilized 18 of the 19 lakes, and their mean (±SE) trip lengths(hours) ranged from 0.80 (0.31) to 7.75 (6.75), depending on the waterbody. In contrast, boat anglers utilized 14 of the 19 lakes, and their trip lengths ranged from 1.39 (0.24) to 4.25 (0.71), depending on the waterbody. The most sought fishes, as indexed by number of lakes on which effort was exerted, were anything (17 of 19 lakes), largemouth bass Micropterus salmoides (15 of 19 lakes), and channel catfish Ictalurus punctatus (13 of 19 lakes). Bluegill Lepomis machrochirus, crappie Pomoxis spp., and largemouth bass were caught most frequently across the lakes, but catch rates varied considerably by lake. Of the1,138 parties interviewed, most parties (93%) visited …

Fishing For Resilience, Kevin L. Pope, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Management approaches that focus on social–ecological systems—systems comprised of ecosystems, landscapes, and humans—are needed to secure the sustainability of inland recreational fisheries without jeopardizing the integrity of the underlying social and ecological components. Resilience management can be useful because it focuses on providing recreational capacity for fishermen under a variety of conditions while assuring that the social– ecological system is not pushed to a critical threshold that would result in a new, undesired system regime. Resilience management is based on a system perspective that accounts for the possible regimes a system could manifest. It aims to enhance system properties that …

Self-Imposed Length Limits In Recreational Fisheries, Christopher J. Chizinski, Dustin R. Martin, Keith L. Hurley, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

A primary motivating factor on the decision to harvest a fish among consumptive-orientated anglers is the size of the fish. There is likely a cost-benefit trade-off for harvest of individual fish that is size and species dependent, which should produce a logistic-type response of fish fate (release or harvest)as a function of fish size and species. We define the self-imposed length limit as the length at which a captured fish had a 50% probability of being harvested, which was selected because it marks the length of the fish where the probability of harvest becomes greater than the probability of release. …

Discontinuities, Cross-Scale Patterns, And The Organization Of Ecosystems, Kirsty L. Nash, Craig R. Allen, David G. Angeler, Chris Barichievy, Tarsha Eason, Ahjond S. Garmestani, Nicholas A. J. Graham, Dean Granholm, Melinda Knutson, R. John Nelson, Magnus Nyström, Craig A. Stow, Shana M. Sundstrom

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Ecological structures and processes occur at specific spatiotemporal scales, and interactions that occur across multiple scales mediate scale-specific (e.g., individual, community, local, or regional) responses to disturbance. Despite the importance of scale, explicitly incorporating a multi-scale perspective into research and management actions remains a challenge. The discontinuity hypothesis provides a fertile avenue for addressing this problem by linking measureable proxies to inherent scales of structure within ecosystems. Here we outline the conceptual framework underlying discontinuities and review the evidence supporting the discontinuity hypothesis in ecological systems. Next we explore the utility of this approach for understanding cross-scale patterns and the …

Predicted Avian Responses To Bioenergy Development Scenarios In An Intensive Agricultural Landscape, Daniel R. Uden, Craig R. Allen, Rob B. Mitchell, Tim D. Mccoy, Qingfeng Guan

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Conversion of native prairie to agriculture has increased food and bioenergy production but decreased wildlife habitat. However, enrollment of highly erodible cropland in conservation programs has compensated for some grassland loss. In the future, climate change and production of second-generation perennial biofuel crops could further transform agricultural landscapes and increase or decrease grassland area. Switchgrass (Panicum virgatum) is an alternative biofuel feedstock that may be economically and environmentally superior to maize (Zea mays) grain for ethanol production on marginally productive lands. Switchgrass could benefit farmers economically and increase grassland area, but there is uncertainty as to how conversions between rowcrops, …

Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Environmental law is intimately connected to ecological concepts and understanding. The legal instruments, institutions, and administration of law in the United States are predicated on assumptions that nature is globally stable and that the inherent variability in ecological systems is bounded. This current legal framework is based upon an understanding of ecological systems operating near an equilibrium, or if disturbed, moving back toward an equilibrium. Such assumptions make much current environmental law ill-suited for many pressing environmental issues (Ruhl 1999; Garmestani et al. 2009; Craig 2010; Verchick 2010; Benson and Garmestani 2011). Emerging environmental challenges, such as cross-boundary water governance …

Self-Confidence Of Anglers In Identification Of Freshwater Sport Fish, Christopher J . Chizinski, D. R. Martin, K. L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Although several studies have focused on how well anglers identify species using replicas and pictures, there has been no study assessing the confidence that can be placed in angler’s ability to identify recreationally important fish. Understanding factors associated with low self-confidence will be useful in tailoring education programmes to improve self-confidence in identifying common species. The purposes of this assessment were to quantify the confidence of recreational anglers to identify 13 commonly encountered warm water fish species and to relate self-confidence to species availability and angler experience. Significant variation was observed in anglers selfconfidence among species and levels of self-declared …
