Integrated Model Of Municipal Waste Management Of The Czech Republic, Jiří Hřebíček, Jana Soukopová Jul 2010

Integrated Model Of Municipal Waste Management Of The Czech Republic, Jiří Hřebíček, Jana Soukopová

International Congress on Environmental Modelling and Software

An integrated model of municipal waste management of the Czech Republic was developed as a balanced network model for a set of municipal solid waste (MSW) sources (mostly municipalities) connected with a set of chosen waste treatment facilities processing their waste. The model involves composting, energy utilisation, material recycling, and land-filling. It is implemented as a combination of four sub-models (GIS transport submodel, quantification and composition of MSW sub-models, cost economic sub-models of all facilities and sub-model optimizing greenhouse gases expressed as CO2 equivalent) and it is easily scalable. It enables the optimisation of environmental impacts (land-filling and greenhouse emissions). …

Integrated Meta-Modelling For Decision Support In Integrated Catchment Management, Vikas Kumar, A. Holzkämper, D. N. Lerner Jul 2010

Integrated Meta-Modelling For Decision Support In Integrated Catchment Management, Vikas Kumar, A. Holzkämper, D. N. Lerner

International Congress on Environmental Modelling and Software

Developing supporting models for multidisciplinary, uncertain and complex Integrated Catchment Management (ICM) is a highly challenging task. Knowledge from multiple disciplines must be integrated, and the process is compounded by significant uncertainty. The key gap that provides the research context is the need for a holistic modelling framework to support ICM, able to capture system complexities and interrelationships, and identify long-term solutions to catchment management problems. In this paper, we present the feasibility study of a new framework for developing an integrated meta-model for decision-support in ICM. The study undertaken by the Catchment Science Centre at the University of Sheffield …

Feedbacks In Socio-Environmental Land Systems, Joerg A. Priess, Nina Schwarz, Sven Lautenbach Jul 2010

Feedbacks In Socio-Environmental Land Systems, Joerg A. Priess, Nina Schwarz, Sven Lautenbach

International Congress on Environmental Modelling and Software

The dynamics of socio-environmental systems are driven by exogenous forcesand by the interaction of endogenous system components, both within the social and environmentalrealms, as well as between them. In recent years, the number of models andmodelling frameworks explicitly representing feedbacks has increased, especially for modelsof land use systems. Land use changes are on the one hand caused by a complex interactionof human and/or institutional land use demands and the environment, which supportsor limits human use in several aspects. On the other hand, land use changes and theireffects at least partly influence the respective driving forces and future land-use decisions,e.g. by …

Habitat Models As A Research Gap In Biodiversity Conservation In Tropical Rain Forest Of Southeast Asia, Mona Nazeri, Jusoff Kamaruzzaman, Nima Madani Jul 2010

Habitat Models As A Research Gap In Biodiversity Conservation In Tropical Rain Forest Of Southeast Asia, Mona Nazeri, Jusoff Kamaruzzaman, Nima Madani

International Congress on Environmental Modelling and Software

Tropical rain forests, the richest terrestrial ecosystem on earth are disappearing due to land use changes mainly agricultural activities and timber logging. Habitat alteration and as a result fragmentation have direct effect on species survival trough lose of connectivity between suitable habitats. Without a doubt the traditional strategies for protecting different wildlife species in this region was not successful enough to guarantee the survival of remaining biodiversity. Distribution modelling which, very little has been studied in the region, is significantly important for biodiversity conservation programs. Distribution data can determine all the areas that can have high potential of occupancy by …

Multi-Scale Modelling Of Ecosystem Services – An Iterative Approach, M. S. Castellazzi, I. Brown, L. Poggio, Alessandro Gimona Jul 2010

Multi-Scale Modelling Of Ecosystem Services – An Iterative Approach, M. S. Castellazzi, I. Brown, L. Poggio, Alessandro Gimona

International Congress on Environmental Modelling and Software

Ecosystems are dependent upon the interactions between the natural environment and human factors. Each different ecosystem service is also associated with varying spatial scales related to their functioning and human benefits. Thus, key requirements for an ecosystem-based approach (EBA) are i) multiple scales, especially landscape scale, ii) flexible method for adaptive response and iii) stakeholders participation. Understanding complex inter-relationships between ecosystem functions and their services requires tools to handle change and uncertainty, notably scenarios and sensitivity analysis. We propose an iterative approach, which is multi-scale and userfocused based upon the LandSFACTS toolkit to generate a suite of land use change …

Nonlinear Optimization For Improving The Operation Of Sewer Systems: The Bogot´A Case Study., J. M. Giraldo, S. Leirens, Mario Díaz-Granados, Juan Pablo Rodríguez Jul 2010

Nonlinear Optimization For Improving The Operation Of Sewer Systems: The Bogot´A Case Study., J. M. Giraldo, S. Leirens, Mario Díaz-Granados, Juan Pablo Rodríguez

International Congress on Environmental Modelling and Software

Sewer systems are considered as complex large-scale systems that traditionally collect and transport stormwater and sanitary sewage out from urban areas. Each subsystem is in itself composed of a large number of elements with time-varying behavior, exhibiting several operating modes and subject to changes due to external conditions and operational constraints. Sewer systems are mainly operated using pumping stations and pollutants are removed from sewage by treatment plants before water is released into the environment. When a sewer overflow occurs, e.g., caused by a strong rainfall, sewage is discharged directly into the environment with some dilution but without treatment. An …

Uncertainty Propagation Throughout An Integrated Water-Quality Model, Gabriele Freni, G. Mannina, G. Viviani Jul 2010

Uncertainty Propagation Throughout An Integrated Water-Quality Model, Gabriele Freni, G. Mannina, G. Viviani

International Congress on Environmental Modelling and Software

In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements in the different parts of the system. Uncertainty basically propagates throughout a chain of models in which simulation output from upstream models is transferred to the downstream ones as input. The overall uncertainty can differ from the simple sum of uncertainties generated in each …

Interacting Environmental Interfaces: Synchronization In Substance Exchange Between Environmental Interfaces Regarded As Biophysical Complex Systems, Dragutin T. Mihailović, M. Budincevic, D. Perisic, Igor Balaž, A. Firanj Jul 2010

Interacting Environmental Interfaces: Synchronization In Substance Exchange Between Environmental Interfaces Regarded As Biophysical Complex Systems, Dragutin T. Mihailović, M. Budincevic, D. Perisic, Igor Balaž, A. Firanj

International Congress on Environmental Modelling and Software

In modeling environmental interfaces regarded as biophysical complex systems, one of the main tasks is to create an operative interface with the external environment. The interface should provide a robust and prompt translation of the vast diversity of external physical and/or chemical changes into a set of signals that are understandable for a biophysical entity. Although the organization of any system is of crucial importance for its functioning, it should not be forgotten that in biophysical systems we deal with real-life problems where a number of other conditions must be satisfied in order to put the system to work. One …

Emotional Intimacy, Coparenting, And Family Work: A Latent Class Growth Analysis, Adam Michael Galovan Jul 2010

Emotional Intimacy, Coparenting, And Family Work: A Latent Class Growth Analysis, Adam Michael Galovan

Theses and Dissertations

From a family systems theoretical view, this paper uses both variable-oriented and person-oriented research approaches to examine parental marriage as a dynamic, interdependent system, and extends the literature by examining parental marriage across a 15 year time span. Employing latent growth curve analysis of 490 mother-father dyads from the NICHD Study of Early Child Care and Youth Development, this study considers multiple aspects of the relationship husbands and wives have together as spouses (emotional intimacy), parents (ideas about discipline and a child-centered vs. adult-centered orientation to childrearing), coparents (agreement regarding parenting beliefs and discipline), and household managers (agreement on the …

Chemopreventive Effects Of Dietary Selenium And Soy Isoflavones In A Mouse Model Of Prostate Cancer, Trevor Elisha Quiner Jun 2010

Chemopreventive Effects Of Dietary Selenium And Soy Isoflavones In A Mouse Model Of Prostate Cancer, Trevor Elisha Quiner

Theses and Dissertations

Prostate cancer is the most commonly diagnosed non-skin cancer in men and the second leading cause of cancer death in the United States. Prostate cancer, like many cancers, is a disease that generally requires a long period of time to develop and grow before it becomes detectable. This long period of latency makes prostate cancer a candidate for dietary chemoprevention. Soy and selenium (Se), are associated with a decreased risk of prostate cancer. We previously showed that high dietary intake of selenium (Se) and soy isoflavones decreased the expression of the androgen receptor (AR) and AR-regulated genes in the prostates …

Liver Kinase B1/Amp-Activated Protein Kinase Signaling In The Diaphragm, Jacob D. Brown Jun 2010

Liver Kinase B1/Amp-Activated Protein Kinase Signaling In The Diaphragm, Jacob D. Brown

Theses and Dissertations

The Liver Kinase B1 (LKB1)/AMP-Activated Protein Kinase (AMPK) signaling pathway is a major regulator of skeletal muscle metabolic processes. During exercise, LKB1-mediated phosphorylation of AMPK leads to its activation, promoting mitochondrial biogenesis and glucose transport, among other effects. The roles of LKB1 and AMPK have not been fully characterized in the diaphragm. Two methods of AMPK activation were used to characterize LKB1/AMPK signaling in diaphragms from muscle-specific LKB1 knockout (KO) and littermate control (C) mice: (1) acute injection of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) and (2) 5-min direct electrical stimulation (ES) of the diaphragm. Diaphragms were excised 60 minutes post-AICAR injection and …

The Structure And Stability Of Alpha-Helical, Orthogonal-Bundle Proteins On Surfaces, Shuai Wei Jun 2010

The Structure And Stability Of Alpha-Helical, Orthogonal-Bundle Proteins On Surfaces, Shuai Wei

Theses and Dissertations

The interaction of proteins with surfaces is a major problem involved in protein microarrays. Understanding protein/surface interactions is key to improving the performance of protein microarrays, but current understanding of the behavior of proteins on surfaces is lacking. Prevailing theories on the subject, which suggest that proteins should be stabilized when tethered to surfaces, do not explain the experimentally observed fact that proteins are often denatured on surfaces. In an attempt to develop some predictive capabilities with respect to protein/surface interactions, it was asked in previous works if the stabilization/destabilization of proteins on surfaces could be correlated to secondary structure …

Piezoresistive Nano-Composites: Characterization And Applications, Thomas B. Hyatt Jun 2010

Piezoresistive Nano-Composites: Characterization And Applications, Thomas B. Hyatt

Theses and Dissertations

Innovative multifunctional materials are essential to many new sensor applications. Piezoresistive nano-composites make up a promising class of such materials that have the potential to provide a measurable response to strain over a much wider range than typical strain gages. Commercial strain gages are currently dominated by metallic sensors with a useable range of a few percent strain at most. There are, however, many applications that would benefit from a reliable wide-range sensor. These might include the study of explosive behavior, instrumentation of flexible components, motion detection for compliant mechanisms and hinges, human-technology interfaces, and a wide variety of bio-mechanical …

Targeting Complex Cyclic Peptides For Synthesis: The Celogentin And Theonellamide Families, Joshua Wayne Robinson Jun 2010

Targeting Complex Cyclic Peptides For Synthesis: The Celogentin And Theonellamide Families, Joshua Wayne Robinson

Theses and Dissertations

Celogentin C and theonellamide F are a class of natural products that have potential antimitotic behavior. They both contain interesting bicyclic structures with unusual linkages within a central moiety. Celogentin C's highly functionalized tryptophan moiety has two unusual linkages, a β-substituted Leu connection to the C6 of the indole structure that makes up the left-hand ring, and a τ-N connection of the imidazole to the C2 of the indole constructing the right-hand ring. This right-hand ring connection was solved via a novel oxidative coupling procedure developed in our group and the left-hand ring was initially constructed via a radical conjugated …

Utilization Of Phylogenetic Systematics, Molecular Evolution, And Comparative Transcriptomics To Address Aspects Of Nematode And Bacterial Evolution, Scott M. Peat Jun 2010

Utilization Of Phylogenetic Systematics, Molecular Evolution, And Comparative Transcriptomics To Address Aspects Of Nematode And Bacterial Evolution, Scott M. Peat

Theses and Dissertations

Both insect parasitic/entomopathogenic nematodes and plant parasitic nematodes are of great economic importance. Insect parasitic/entomopathogenic nematodes provide an environmentally safe and effective method to control numerous insect pests worldwide. Alternatively, plant parasitic nematodes cause billions of dollars in crop loss worldwide. Because of these impacts, it is important to understand how these nematodes evolve, and, in the case of entomopathogenic nematodes, how their bacterial symbionts evolve. This dissertation contains six chapters. Chapter one is a review of DNA markers and their use in the phylogenetic systematics of entomopathogenic and insect-parasitic nematodes as well as a review of phylogenetic, co-phylogenetic, and …

Organellar Dna Polymerases Gamma I And Ii In Arabidopsis Thaliana, Jeffrey M. Brammer Jun 2010

Organellar Dna Polymerases Gamma I And Ii In Arabidopsis Thaliana, Jeffrey M. Brammer

Theses and Dissertations

Plants have two organelles outside the nucleus which carry their own DNA, mitochondria and chloroplasts. These organelles are descendants of bacteria that were engulfed by their host according to the endosymbiotic theory. Over time, DNA has been exchanged between these organelles and the nucleus. Two polymerases, DNA Polymerases Gamma I and II, are encoded in the nucleus and remain under nuclear control, but are transported into the mitochondria and chloroplasts. DNA polymerases gamma I and II are two organelle polymerases which have been studied through sequence analysis and shown to localize to both mitochondria and chloroplasts. Little has been done …

Proactive Parenting Practices During Early Adolescence: A Cluster Approach, Laura M. Padilla-Walker, Katherine J. Christensen, Randal D. Day Jun 2010

Proactive Parenting Practices During Early Adolescence: A Cluster Approach, Laura M. Padilla-Walker, Katherine J. Christensen, Randal D. Day

Faculty Publications

The purpose of the current study was to explore clusters of proactive parenting practices, and how they might vary as a function of parental demographics, the quality of the parent– child relationship, and the traits and behaviors of the adolescent child. Data were taken from the Flourishing Families Project, which includes 500 families with an early adolescent child (M age ¼ 11.49). Findings suggested that there were four clusters of parents, and patterns were similar for mothers and fathers. Findings also suggested that proactive clusters varied primarily as a function of demographics of the parent (e.g., religiosity, ethnicity, education) and …

Language As A Predictor Of Reticence In Children With Language Impairment, Patricia Anne Moses Jun 2010

Language As A Predictor Of Reticence In Children With Language Impairment, Patricia Anne Moses

Theses and Dissertations

This study examined the relationship between language skills and reticence in 37 children with language impairment (LI) and 37 typically developing peers matched for age (ranging from 6;11 to 10;1 years) and gender. Subtests of the Comprehensive Assessment of Spoken Language (E. Carrow-Woolfolk, 1999) were used to evaluate language ability. The Teacher Behavior Rating Scale (C. H. Hart & C. C. Robinson, 1996) was used to evaluate reticence. The current study replicated previous research by documenting significantly higher levels of reticence in children with LI when compared to typical peers. Significant group differences were also found in paragraph comprehension, syntax …

Infrageneric Relationships Within Collomia (Polemoniaceae), Eric Stewart Green Jun 2010

Infrageneric Relationships Within Collomia (Polemoniaceae), Eric Stewart Green

Theses and Dissertations

Traditional evolutionary models depict evolution as a bifurcating pattern with a single ancestor diverging to form two lineages. However, reticulate species resulting from hybridization and recombination have unique histories shared with two independent lineages, not one. Accounting for the genetic histories of reticulate species increases the power and ability to recover biologically meaningful relationships. The genus Collomia (Polemoniaceae) is used to explore issues of reticulation and the importance of accounting for gene histories in a phylogenetic analysis. The issue of reticulation within species trees is discussed with a multilabeled, network approach being explored to better represent the genus's evolutionary history. …

On The Use Of Cartographic Projections In Visualizing Phylogenetic Treespace, Mark J. Clement, Quinn O. Snell, Kenneth Sundberg Jun 2010

On The Use Of Cartographic Projections In Visualizing Phylogenetic Treespace, Mark J. Clement, Quinn O. Snell, Kenneth Sundberg

Faculty Publications

Phylogenetic analysis is becoming an increasingly important tool for biological research. Applications include epidemiological studies, drug development, and evolutionary analysis. Phylogenetic search is a known NP-Hard problem. The size of the data sets which can be analyzed is limited by the exponential growth in the number of trees that must be considered as the problem size increases. A better understanding of the problem space could lead to better methods, which in turn could lead to the feasible analysis of more data sets. We present a definition of phylogenetic tree space and a visualization of this space that shows significant exploitable …

Investigating Executive Functions In Men Seeking Help For Hypersexual Behavior Using Neuropsychological Testing, Rory C. Reid Jun 2010

Investigating Executive Functions In Men Seeking Help For Hypersexual Behavior Using Neuropsychological Testing, Rory C. Reid

Theses and Dissertations

Patients seeking help for hypersexual behavior often exhibit features of impulsivity, cognitive rigidity, poor judgment, deficits in emotion regulation, and excessive preoccupation with sex. Some of these characteristics are also common among patients presenting with neurological pathology associated with executive dysfunction. These observations led to the current investigation in which differences across scores on objective neuropsychological tests of executive functioning were explored in a group of hypersexual male patients (n = 30) compared with a non-hypersexual community sample (n = 30) of men. Using multivariate statistics, differences between the groups were examined yielding significant differences on measures of hypersexuality. However, …
