Estimating The Biomass Of Hand-Piled Fuels For Smoke Management Planning, Clinton S. Wright, Robert E. Vilnanek, James Russell, Mark Middy, Jim Bailey, Steve Davis, Robert Sanders, Cameron Balog, Paige Eagle Jan 2009

Estimating The Biomass Of Hand-Piled Fuels For Smoke Management Planning, Clinton S. Wright, Robert E. Vilnanek, James Russell, Mark Middy, Jim Bailey, Steve Davis, Robert Sanders, Cameron Balog, Paige Eagle

Joint Fire Science Program Research Project Reports

Dimensions, volume, and biomass were measured for 121 hand-constructed piles composed primarily of coniferous (n=61) and shrub/hardwood (n=60) material at sites in Washington and California. Equations using pile dimensions, shape, and type allow users to accurately estimate the biomass of hand piles. Equations for estimating true pile volume from simple geometric shapes and measurements of pile dimensions were also developed to allow users who require estimates of pile volume for regulatory reporting. Biomass and volume estimation equations are being programmed into a web-based calculator to allow users to estimate either value from pile dimensions.

Reducing Fine Fuel Loads, Controlling Invasive Annual Grasses, And Manipulating Vegetation Composition In Zion Canyon, Utah, J. R. Matchett, Aviva O'Neill, Matt Brooks, Cheryl Decker, Jennifer Vollmer, Curt Deuser Jan 2009

Reducing Fine Fuel Loads, Controlling Invasive Annual Grasses, And Manipulating Vegetation Composition In Zion Canyon, Utah, J. R. Matchett, Aviva O'Neill, Matt Brooks, Cheryl Decker, Jennifer Vollmer, Curt Deuser

Joint Fire Science Program Research Project Reports

Fine fuels created by non-native annual grasses are a land management problem throughout the United States and beyond. These fuels facilitate the ignition of wildfires and promote their spread, creating hazardous fuel conditions in wildland urban interface areas. For example, fine fuel accumulations from non-native annual grasses in the riparian corridor at Zion National Park threaten the few egress routes from Zion Canyon, creating a threat to human life should a large wildfire occur there. In addition, when these non-native plants create novel fuel characteristics and fire behavior, they can lead to altered fire regimes that can significantly degrade natural …

Joint Fire Science Program Research Project Reports

The Healthy Forest Restoration Act of 2003 (HFRA) was enacted to reduce wildfire risk to communities and other at-risk lands through a collaborative process of planning, prioritizing and implementing hazardous fuel reduction projects. One of the key features of HFRA is the development of community wildfire protection plans (CWPPs). We studied the development of CWPPs in order to identify those factors and processes that consistently lead to effective collaborative fire and fuels management as defined by HFRA, and enhance local social capacity to sustain wildfire protection activities into the future. Findings from this research highlight the importance of: (1) drawing …

Characterizing Particulate Matter Emissions By Wildland Fires Relevant To Visibility Impairment And Pm Non-Attainment, William Malm, Douglas Fox, Hans Moosmüller, Sonia Kreidenweis, Jeffrey Collett Jr., Wei Min Hao Jan 2009

Characterizing Particulate Matter Emissions By Wildland Fires Relevant To Visibility Impairment And Pm Non-Attainment, William Malm, Douglas Fox, Hans Moosmüller, Sonia Kreidenweis, Jeffrey Collett Jr., Wei Min Hao

Joint Fire Science Program Research Project Reports

Carbonaceous aerosols, which include contributions from industrial and mobile source emissions and biomass combustion, exert a significant impact on regional air quality. Some preliminary semi-quantitative analyses suggest that smoke from fire-related activity may contribute significantly to observed organic mass concentrations. Further, these emissions have resulted in increased conflicts with the need to attain air quality standards, especially for particulate matter (PM) and visibility, as mandated by the Clean Air Act. However, federal land managers and policy makers currently lack several important tools needed for air quality assessments: composition profiles and analytical techniques necessary to differentiate carbonaceous aerosols originating from industrial …

Joint Fire Science Program Research Project Reports

Today, park managers must routinely balance the restoration needs of natural resources with the preservation of cultural resources. This project was designed to provide park managers with scientific data on the impacts from wildland fire to archeological resources at National Park Service units in the Midwest Region. Experimental research was conducted at six parks to record data on fire conditions (i.e., fuels, fire temperature, and burn duration) and the impacts on multiple classes of archeological materials routinely observed at sites within the region. The experimental study of fire conditions in different regional environments addresses questions regarding the threats or non-threats …

A Regional Assessment Of The Ecological Effects Of Chipping And Mastication Fuels Reduction And Forest Restoration Treatments., Mike Battaglia, Charles Rhoades, Monique E. Rocca, Michael G. Ryan Jan 2009

A Regional Assessment Of The Ecological Effects Of Chipping And Mastication Fuels Reduction And Forest Restoration Treatments., Mike Battaglia, Charles Rhoades, Monique E. Rocca, Michael G. Ryan

Joint Fire Science Program Research Project Reports

Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of shrubs and small-diameter trees through chipping and shredding. Mastication is a relatively untested management practice that alters the chemical and physical conditions of the forest floor and may influence vegetation regrowth and fuel development for years or decades. Eighteen sites were established across four ecosystems of the southern Rocky Mountains and the Colorado Plateau: lodgepole pine (Pinus contorta), mixed conifer (Pinus ponderosa, Pseudotsuga menziesii, Pinus flexilis, and Pinus contorta), ponderosa pine (Pinus ponderosa), and pinyon pine/juniper …

Fire And Fuels Management In Coast Redwood Forests, Steven P. Norman, J. Morgan Varner, Leonel Arguello, Stephen Underwood, Bradley Graham, Greg Jennings, Yana Valachovic, Christopher Lee Jan 2009

Fire And Fuels Management In Coast Redwood Forests, Steven P. Norman, J. Morgan Varner, Leonel Arguello, Stephen Underwood, Bradley Graham, Greg Jennings, Yana Valachovic, Christopher Lee

Joint Fire Science Program Research Project Reports

Coast redwood forests rank among the most significant natural features of North America, yet our understanding of how they came to be and how we might sustain them has been beset by scientific and management uncertainty for decades. A key part of this controversy has been the historical importance of fire given the mild coastal climate and small number of lightning ignitions. In the northern part of the coast redwood range, past research found that fire was uncommon, but results conflicted with others that found fire to be as frequent as in any dry forest of western North America. We …

Joint Fire Science Program Research Project Reports

Department of the Interior (DOI) bureaus have invested heavily (for example, the U.S. Bureau of Land Management (BLM) spent more than $60 million in fiscal year 2007) in seeding vegetation for emergency stabilization and burned area rehabilitation of non-forested arid lands over the past 10 years. The primary objectives of these seedings commonly are to (1) reduce the post-fire dominance of non-native annual grasses, such as cheatgrass (Bromus tectorum) and red brome (Bromus rubens); (2) minimize the probability of recurrent fire; and (3) ultimately produce desirable vegetation characteristics (for example, ability to recover following disturbance [resilience], resistance to invasive species, …

Extending The Reach Of The Fire Effects Planning Framework By Taking A Critical Approach To Science Delivery And Application, Anne E. Black, Carol Miller, Vita Wright, Kate Walker, Carolyn Ballard, Paula Nasiatka, Brett Fay, Linda Chappell, Dave Calkin

Joint Fire Science Program Research Project Reports

The Fire Effects Planning Framework (FEPF), developed under JFSP project (99-1-3-16) “Wildland fuels management: evaluating and planning risks and benefits,” was formally completed in June 2004. FEPF is a logical framework that uses available data (e.g., local, LANDFIRE data) and existing software (e.g., GIS, Farsite, FlamMap, expert knowledge) to produce maps of probable fire effects during the pre-season or in advance of a fire front. The initial project included significant technology transfer activities. As that project concluded, however, we continued to receive requests for assistance from field managers (District, Forest and Regional Forest Service offices), international organizations (Interior West Fire …

Rules And Insights: Connecting The Mathematical And Linguistic Abilities Of C.S. Lewis, Kim Regnier Jongerius Jan 2009

Rules And Insights: Connecting The Mathematical And Linguistic Abilities Of C.S. Lewis, Kim Regnier Jongerius

ACMS Journal 2008-2009

While most biographical works on C.S. Lewis give passing reference to Lewis' problems with elementary mathematics, few have made an attempt at diagnosing the difficulty or exploring its impact on his writing. A careful study of family correspondence, however, makes it clear that his learning difficulties were not with mathematics alone and suggests connections between attitudes toward and abilities in both mathematics and language. This paper will make these connections clear and will illustrate their ties to Lewis' effective mathematical references.

The microRNA miR-7 is perfectly conserved from annelids to humans, and yet some of the genes that it regulates in Drosophila are not regulated in mammals. We have explored the role of lineage restricted targets, using Drosophila , in order to better understand the evolutionary significance of microRNA-target relationships. From studies of two well characterized developmental regulatory networks, we find that miR-7 functions in several interlocking feedback and feedforward loops, and propose that its role in these networks is to buffer them against perturbation. To directly demonstrate this function for miR-7, we subjected the networks to temperature fluctuation and found …

Gene Expression Profile In Leucocytes Of Type 2 Diabetic Subjects, S. Kaviarasan, S. Muniandy, R. Qvist, I.S. Ismail

Research Publications (2006 to 2010)

Communication between insulin target tissues and beta-cells initiate compensatory responses which increase insulin production. Correlated changes, in gene expression between tissues, can provide evidence for such intercellular communication. We profiled gene expression studies in Type 2 diabetic subjects to unveil the mechanistic factors involved. Our results showed that genes involved in carbohydrate, lipid and amino acid metabolism pathways, glycan of biosynthesis, metabolism of cofactors and vitamin pathways, ubiquitin-mediated proteolysis, signal transduction pathways, neuroactive ligand receptor interaction were upregulated in diabetes compared to healthy subjects. In contrast, genes involved in cell adhesion, cytokine-cytokine receptor interaction, insulin signaling, PPAR signaling pathways were …

Algorithm For The Analysis Of Tryptophan Flourescence Spectra And Their Correlation With Protein Structural Parameters, John Hixon, Yana K. Reshetnyak

Physics Faculty Publications

The fluorescence properties of tryptophan residues are sensitive to the microenvironment of fluorophores in proteins. Therefore, fluorescence characteristics are widely used to study structural transitions in proteins. However, the decoding of the structural information from spectroscopic data is challenging. Here we present a review of approaches developed for the decomposition of multi-component protein tryptophan fluorescence spectra and correlation of these spectral parameters with protein structural properties.

Solid tumors often develop an acidic environment due to the Warburg effect. The effectiveness of diagnosis and therapy may therefore be enhanced by the design and use of pH-sensitive agents that target acidic tumors. Recently, a novel technology was introduced to target acidic tumors using pH low insertion peptide (pHLIP), a peptide that inserts across cell membranes as an α-helix when the extracellular pH (pHe) is acidic. In this study, we expanded the application of the pHLIP technology to include positron emission tomography imaging of the acidic environment in prostate tumors using 64Cu conjugated to the pHLIP …
