Seed Rain And Selected Species Germination And Growth Trials: Implications For Natural And Augmented Revegetation Of Post-Dam Elwha River Floodplain And Reservoir Sediments, James T. Michel 2010 Western Washington University

Seed Rain And Selected Species Germination And Growth Trials: Implications For Natural And Augmented Revegetation Of Post-Dam Elwha River Floodplain And Reservoir Sediments, James T. Michel

WWU Masters Thesis Collection

The removal of Glines Canyon and Elwha dams from the Elwha River in Olympic National Park, Washington State is scheduled to begin in 2011. This undertaking is among the largest planned dam removals and ecosystem restoration projects in the world. One of the challenges associated with this restoration will be to understand processes influencing revegetation and invasive species colonization on the sediments exposed by dam removal. To help characterize post-dam vegetation succession within the Elwha River floodplain and dewatered reservoirs, we undertook field collections of reservoir sediments and seed rain during summer 2008. We then conducted two greenhouse experiments 1 ...


Viability Of Coho Salmon Oncorhynchus Kisutch In Relation To Streamflow Regulation In Terrell Creek, Washington, Ryan S. Vasak 2010 Western Washington University

Viability Of Coho Salmon Oncorhynchus Kisutch In Relation To Streamflow Regulation In Terrell Creek, Washington, Ryan S. Vasak

WWU Masters Thesis Collection

As salmon and trout populations decline in the Pacific Northwest, emphasis should be placed on restoration of any stream capable of producing salmon and trout. Terrell Creek is a small, dam regulated, independent drainage that historically produced at least four species of salmon and trout. Streamflow, regulated at the Lake Terrell dam, has typically been close to zero during the summer low flow period and probably affected salmon and trout population levels in the Creek. This study was designed to characterize the current fish assemblage in Terrell Creek, estimate coho salmon (Oncorhynchus kisutch) smolt production levels, identify factors that limit ...


Habitat Modeling Using Path Analysis: Delineating Mountain Goat Habitat In The Washington Cascades, Tana Beus 2010 Western Washington University

Habitat Modeling Using Path Analysis: Delineating Mountain Goat Habitat In The Washington Cascades, Tana Beus

WWU Masters Thesis Collection

A 70-90% decline in mountain goat (Oreamnos americanus) populations in Washington State over the past few decades has spurred the need for an improved understanding of seasonal goat-habitat relationships. Habitat use data have been collected from 46 radio-collared mountain goats across their native range in Washington State. Using Geographical Information Systems (GIS), I explored relationships between use and availability of habitat. To overcome issues of autocorrelation, I compared actual mountain goat paths with available paths of matched identical spatial topology and used multi-scale path analysis to explore various ecologically informed relationships between landscape structure and the movements of mountain goats ...


Rethinking Biodiversity Conservation Effectiveness And Evaluation In The National Protected Areas Systems Of Tropical Islands: The Case Of Jamaica And The Dominican Republic, Suzanne Mae Camille Davis 2010 Wilfrid Laurier University

Rethinking Biodiversity Conservation Effectiveness And Evaluation In The National Protected Areas Systems Of Tropical Islands: The Case Of Jamaica And The Dominican Republic, Suzanne Mae Camille Davis

Theses and Dissertations (Comprehensive)

Island conservation theory and practice with regard to conservation of tropical terrestrial biodiversity in protected areas systems has yet to be adequately addressed in conservation literature. This knowledge gap is identified as a key contributor to the adoption of scientific principles for in situ biodiversity conservation, and “universal” conservation and protected area management paradigms that are unsuitable for island contexts and geographical scale. The underlying assumption is that “universal” concepts of biodiversity conservation, protected areas management, and evaluation of their effectiveness are transferable to the ecological and socio-economic contexts of tropical islands. The expected outcome of this knowledge transfer is ...


Microporous Organic Polymers: Synthesis And Post Synthetic Modifications, Phillip Andrew Kerneghan 2010 Wilfrid Laurier University

Microporous Organic Polymers: Synthesis And Post Synthetic Modifications, Phillip Andrew Kerneghan

Theses and Dissertations (Comprehensive)

Microporous solids are an important class of materials that have been studied extensively. Newer to this field are Microporous Organic Polymers (MOPs) which are networks constructed from smaller organic building blocks and exhibit large surface areas, small pore sizes and low densities. It is due to these characteristics that MOPs have attracted attention because of their potential use in applications such as catalysis, chemical separations and gas storage.

In this thesis is described the synthesis of two novel MOPs, the first of which being a network based on benzenediboronic acid and triptycene building blocks linked together by boronate esters. This ...


Provenance Aware Linked Sensor Data, Harshal Kamlesh Patni, Satya S. Sahoo, Cory Andrew Henson, Amit P. Sheth 2010 Wright State University - Main Campus

Provenance Aware Linked Sensor Data, Harshal Kamlesh Patni, Satya S. Sahoo, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

Provenance, from the French word “provenir”, describes the lineage or history of a data entity. Provenance is critical information in the sensors domain to identify a sensor and analyze the observation data over time and geographical space. In this paper, we present a framework to model and query the provenance information associated with the sensor data exposed as part of the Web of Data using the Linked Open Data conventions. This is accomplished by developing an ontology-driven provenance management infrastructure that includes a representation model and query infrastructure. This provenance infrastructure, called Sensor Provenance Management System (PMS), is underpinned by ...


Does Co-Opetition Change The Game? A Bayesian Analysis Of Participation Strategy In An Industry Standard-Setting Organization, Robert J. KAUFFMAN, Benjamin B. M. SHAO, Juliana Y. TSAI 2010 Singapore Management University

Does Co-Opetition Change The Game? A Bayesian Analysis Of Participation Strategy In An Industry Standard-Setting Organization, Robert J. Kauffman, Benjamin B. M. Shao, Juliana Y. Tsai

Research Collection School Of Information Systems

Across different industries, we observe the emergence of industry standard-setting organizations (SSO) that focus on the creation of industry-specific process standards. Firms adopt a strategy of co-opetition, the combination of cooperation and competition, during standards development. We propose that a firm's co-opetition strategy is revealed to some extent by when it elects to participate in an industry SSO. Bayesian information updating offers an effective empirical modeling perspective for studying firms' participation strategies when managers' beliefs and uncertainties are factored into their decision-making. We analyze a panel data set of 73 U.S. public firms over a 20-year period. These ...


A Review Of The Professionalization Of The Software Industry: Has It Made Software Engineering A Real Profession?, Heng Ngee Mok 2010 Singapore Management University

A Review Of The Professionalization Of The Software Industry: Has It Made Software Engineering A Real Profession?, Heng Ngee Mok

Research Collection School Of Information Systems

Every industry strives to be called a "profession", and software engineering is no exception. This paper attempts to define "profession" from three different perspectives and provides a chronological narration of the professionalization efforts of major IT bodies such as the IEEE Computer Society, Association of Computing Machinery and British Computer Society to promote software engineering from "occupation" to "profession". The outcome of this professionalization process is then examined against the three vastly different definitions of "profession" to qualitatively gauge the success of the professionalization process.


Bh3-Only Proteins Bim And Puma In The Regulation Of Survival And Neuronal Differentiation Of Newly Generated Cells In The Adult Mouse Hippocampus., Eva C. Bunk, Hans-Georg König, Tytus Bernas, Tobias Engel, David C. Henshall, Brian P. Kirby, Jochen HM Prehn 2010 Royal College of Surgeons in Ireland

Bh3-Only Proteins Bim And Puma In The Regulation Of Survival And Neuronal Differentiation Of Newly Generated Cells In The Adult Mouse Hippocampus., Eva C. Bunk, Hans-Georg König, Tytus Bernas, Tobias Engel, David C. Henshall, Brian P. Kirby, Jochen Hm Prehn

Physiology and Medical Physics Articles

Neurogenesis persists in the adult hippocampus, where several thousand neurons are born every day. Most of the newly generated cells are eliminated by apoptosis, possibly because of their failure to integrate properly into neural networks. The BH3-only proteins Bim and Puma have been shown to mediate trophic factor withdrawal- and anoikis-induced apoptosis in various systems. We therefore determined their impact on proliferation, survival, and differentiation of adult-generated cells in the mouse hippocampus using gene-deficient mice. Wild-type, bim-, and puma-deficient mice showed similar rates of precursor cell proliferation, as evidenced by 5-bromo-2-deoxyuridine (BrdU)-incorporation. Deficiency in either bim or puma significantly ...


Sulfated Zirconia Modified Sba-15 Catalysts For Cellobiose Hydrolysis, Volkan Degirmenci, Deniz Uner, Basak Cinlar, Brent H. Shanks, Aysen Yilmaz, Rutget A. van Santen, Emiel J. M. Hensen 2010 Middle East Technical University

Sulfated Zirconia Modified Sba-15 Catalysts For Cellobiose Hydrolysis, Volkan Degirmenci, Deniz Uner, Basak Cinlar, Brent H. Shanks, Aysen Yilmaz, Rutget A. Van Santen, Emiel J. M. Hensen

Chemical and Biological Engineering Publications

Zirconia modified SBA-15 becomes a very active catalyst for the selective hydrolysis of cellobiose to glucose after sulfation. Spectroscopic investigations indicate the presence of Brønsted acid sites with similar properties to those present in conventional sulfated zirconia. Indications are found that the sulfate groups attached to zirconia interact with silanol groups of SBA-15. The catalytic activity in cellobiose hydrolysis correlates well with results for temperature-programmed decomposition of i-propylamine for a range of sulfated ZrO2/SBA-15 catalysts. A glucose yield of 60% during cellobiose hydrolysis at a reaction time of 90 min at 160° C is obtained.

Theoretical Study Of The Pyrolysis Of Methyltrichlorosilane In The Gas Phase. 3. Reaction Rate Constant Calculations, Yingbin Ge, Mark S. Gordon, Francine Battaglia, Rodney O. Fox

Chemical and Biological Engineering Publications

The rate constants for the gas-phase reactions in the silicon carbide chemical vapor deposition of methyltrichlorosilane (Ge, Y. B.; Gordon, M. S.; Battaglia, F.; Fox, R. O. J. Phys. Chem. A 2007, 111, 1462.) were calculated. Transition state theory was applied to the reactions with a well-defined transition state; canonical variational transition state theory was applied to the barrierless reactions by finding the generalized transition state with the maximum Gibbs free energy along the reaction path. Geometry optimizations were carried out with second-order perturbation theory (MP2) and the cc-pVDZ basis set. The partition functions were calculated within the harmonic oscillator ...

Chemical and Biological Engineering Publications

Protein-lean fractions of corn (maize) containing recombinant (r) pharmaceutical proteins were evaluated as a potential feedstock to produce fuel ethanol. The levels of residual r-proteins in the coproduct, distillers dry grains with solubles (DDGS), were determined. Transgenic corn lines containing recombinant green fluorescence protein (r-GFP) and a recombinant subunit vaccine of Escherichia coli enterotoxin (r-LTB), primarily expressed in endosperm, and another two corn lines containing recombinant human collagen (r-CIα1) andr-GFP, primarily expressed in germ, were used as model systems. The kernels were either ground and used for fermentation or dry fractionated to recover germ-rich ...


An Extended Data Mining Method For Identifying Differentially Expressed Assay-Specific Signatures In Functional Genomic Studies, Derrick K. Rollins Sr., Ai-ling Teh 2010 Iowa State University

An Extended Data Mining Method For Identifying Differentially Expressed Assay-Specific Signatures In Functional Genomic Studies, Derrick K. Rollins Sr., Ai-Ling Teh

Chemical and Biological Engineering Publications

Background: Microarray data sets provide relative expression levels for thousands of genes for a small number, in comparison, of different experimental conditions called assays. Data mining techniques are used to extract specific information of genes as they relate to the assays. The multivariate statistical technique of principal component analysis (PCA) has proven useful in providing effective data mining methods. This article extends the PCA approach of Rollins et al. to the development of ranking genes of microarray data sets that express most differently between two biologically different grouping of assays. This method is evaluated on real and simulated data and ...


On The Equivalence Between Real Mutually Unbiased Bases And A Certain Class Of Association Schemes, Nicholas LeCompte, William J. Martin, William Owens 2010 Worcester Polytechnic Institute

On The Equivalence Between Real Mutually Unbiased Bases And A Certain Class Of Association Schemes, Nicholas Lecompte, William J. Martin, William Owens

Mathematical Sciences Faculty Publications

Mutually unbiased bases (MUBs) in complex vector spaces play several important roles in quantum information theory. At present, even the most elementary questions concerning the maximum number of such bases in a given dimension and their construction remain open. In an attempt to understand the complex case better, some authors have also considered real MUBs, mutually unbiased bases in real vector spaces. The main results of this paper establish an equivalence between sets of real mutually unbiased bases and 4-class cometric association schemes which are both Q-bipartite and Q-antipodal. We then explore the consequences of this equivalence, constructing new cometric ...


Metabolic Engineering For Production Of Biorenewable Fuels And Chemicals: Contributions Of Synthetic Biology, Laura R. Jarboe, Xueli Zhang, Xuan Wang, Jonathan C. Moore, K. T. Shanmugam, Lonnie O. Ingram 2010 Iowa State University

Metabolic Engineering For Production Of Biorenewable Fuels And Chemicals: Contributions Of Synthetic Biology, Laura R. Jarboe, Xueli Zhang, Xuan Wang, Jonathan C. Moore, K. T. Shanmugam, Lonnie O. Ingram

Chemical and Biological Engineering Publications

Production of fuels and chemicals through microbial fermentation of plant material is a desirable alternative to petrochemicalbased production. Fermentative production of biorenewable fuels and chemicals requires the engineering of biocatalysts that can quickly and efficiently convert sugars to target products at a cost that is competitive with existing petrochemical-based processes. It is also important that biocatalysts be robust to extreme fermentation conditions, biomass-derived inhibitors, and their target products. Traditional metabolic engineering has made great advances in this area, but synthetic biology has contributed and will continue to contribute to this field, particularly with next-generation biofuels. This work reviews the use ...

Limit On Continuous Neutrino Emission From Neutron Stars, Itzhak Goldman, Shmuel Nussinov 2010 Afeka College of Engineering

Limit On Continuous Neutrino Emission From Neutron Stars, Itzhak Goldman, Shmuel Nussinov

Mathematics, Physics, and Computer Science Faculty Articles and Research

The timing data of the binary pulsar PSR1913+16, are used to establish an upper limit on the rate of continuous neutrino emission from neutron stars. Neutrino emission from each of the neutron stars of the binary system, increases the star binding energy and thus translates to a decrease in their masses. This in turn implies an increase with time of the binary period. Using the pulsar data we obtain an upper limit on the allowed rate of mass reduction: vertical bar M vertical bar < 1.1 x 10(-12) yr(-1) M, where M is the total mass of the binary. This constrains exotic nuclear equations of state that predict continuous neutrino emissions. The limit applies also to other channels of energy loss, e. g. axion emission. Continued timing measurements of additional binary pulsars, should yield a stronger limit in the future.

Linear Stochastic State Space Theory In The White Noise Space Setting, Daniel Alpay, David Levanony, Ariel Pinhas 2010 Chapman University

Linear Stochastic State Space Theory In The White Noise Space Setting, Daniel Alpay, David Levanony, Ariel Pinhas

Mathematics, Physics, and Computer Science Faculty Articles and Research

We study state space equations within the white noise space setting. A commutative ring of power series in a countable number of variables plays an important role. Transfer functions are rational functions with coefficients in this commutative ring, and are characterized in a number of ways. A major feature in our approach is the observation that key characteristics of a linear, time invariant, stochastic system are determined by the corresponding characteristics associated with the deterministic part of the system, namely its average behavior.
