Displaying 881 - 890 of 64,684 Publications- In 2023, a new generation of National Land Cover Database (NLCD) Tree Canopy Cover (TCC) data were produced that include annual 30m gridded time-series products for the Conterminous United States (CONUS). These NLCD TCC v2021.4 products have more frequent time steps, inter-annual coherency, lower product release latency, improved accuracy, uncertainty metrics, and documentation over previous versions. Our methodology leveraged Google Earth Engine (GEE) to generate annual time-series composites from Landsat and Sentinel-2 imagery that were used to predict annual pixel-wise TCC. Next, we...AuthorsJoshua Heyer, Karen G. Schleeweis, Bonnie Ruefenacht, Ian Housman, Yang Zhiqiang, Daniel Ryerson, Jaclyn Reischmann, Kevin Megown, M.

- Structural insulated panel foams are made primarily from petrochemicals. As a biopolymer, lignin is a promising raw material substitute for foam production. Nondestructive evaluation is routinely used for structural material strength and stiffness assessment. Herein, mechanical acoustic velocity (AV) was used to nondestructively evaluate lignin-foam blocks. Overall, foam block weight was determined, and flying time was measured for various foam thicknesses ranging from 7.26 to 8.89 cm (3.0 to 3.5 in.). Additionally, for each block, AV was measured at several different positions/locations....AuthorsSeyed Abolghasem Fatemi, Rubin Shmulsky, Zhiyong Cai, Qiangu Yan, Zach KyzerSourceForest Products JournalYear2025
- Polyurethane foam is a valuable material with applications across the automotive, packaging, construction, appliance, and furniture industries. However, traditional polyurethane foams are made from petroleumbased precursors including harmful isocyanates. Isocyanates are the leading cause of workplace asthma and are made from toxic phosgene gas, representing a challenge to green chemistry principles. To address these concerns, non-isocyanate polyurethane (NIPU) foams replace the traditional polyurethane reaction with a safer, non-isocyanate process most often employing cyclic carbonates and...AuthorsKathryn Evancho, Richard Reiner, Biljana Bujanovic, Srikanth Pilla, James SternbergKeywordsSourceRSC AdvancesYear2025
- Transient conditions arising from sun exposure of absorptive claddings after being wetted by rain impose significant hygrothermal load on wood-frame walls. In this paper, we show that moisture conditions generated by the inward drive of water vapor increase the risk of mold growth and durability issues in susceptible components of the wall assembly. We present a comprehensive set of one-dimensional hygrothermal simulations on solar-driven moisture diffusion in wood-frame walls with brick cladding and oriented strand board (OSB) sheathing. Sensitivity analysis identifies key material...AuthorsNatalia Farkas, Samuel V. Glass, Samuel L. ZelinkaSourcepaper in proceedingsYear2025
- This study investigates the role of Forest Stewardship Council (FSC) certification in advancing sustainable forest management and influencing forest cover changes across 70 countries from 2000 to 2021. Using dynamic panel data model and Generalized Method of Moments (GMM) estimations, the analysis addresses endogeneity concerns, such as those stemming from lagged dependent variables, providing robust and unbiased estimates. Results indicate that FSC certification significantly enhances forest cover, with the most pronounced effects observed in low- and middle-income countries. Additionally,...AuthorsInoussa Boubacar, Yaya SissokoSourceJournal of Cleaner ProductionYear2025
Comparative Evaluation of the VTT Mold Index Model and the DR SIM Model for Moisture Risk Assessment
Hygrothermal simulations are useful in forensic investigations of moisture problems and in design analysis for identifying and mitigating potential risks both in new construction and retrofit of existing buildings. Damage models, including mold growth models, are often used as a means of assessing risk; such models use simulation outputs such as temperature and relative humidity or moisture content. The Finnish mold growth model (or VTT mold index model), a pioneering model used widely by researchers and practitioners, was developed based on laboratory data for a wide range of materials,...AuthorsSamuel V. Glass, Robert Lepage, Natalia Farkas, Samuel L. ZelinkaKeywordsSourcepaper in proceedingsYear2025- Many studies that use an automated sorption balance to determine a water vapor sorption isotherm for wood collect data until the moisture content change is less than or equal to 0.002% min−1 (20 μg g−1 min−1). This stop criterion has been claimed to give errors in equilibrium moisture content (EMC) predictions of less than 0.001 g g−1 but over the past 10 years, studies have shown that the actual errors can be greater than 0.01 g g−1 because the measurements are stopped well before equilibrium is reached. Despite the large errors associated with this stop criterion, it remains popular due...AuthorsSamuel L. Zelinka, Samuel V. Glass, Natalia Farkas, Emil E.

- Nearly 86% of forestlands in the Southern United States are owned by private forest landowners, and about twothirds of this area is owned by Family Forest Owners (FFOs). Forest legacy planning is crucial for ensuring the long-term sustainability of these forests. It includes formal aspects, such as estate planning, and informal aspects, such as discussions with the next generation about forest management plans. This study examines the factors that influence landowners’ estate planning decisions. We evaluate how landowners’ characteristics, behaviors, and motivations influence their estate...AuthorsAna Cubas-Baez, Rajan Parajuli, Erin O Sills, Frederick W Cubbage, Gregory E.

- Increasing participation in outdoor recreation is driving elevated levels of human presence in wildlands. If properly managed, outdoor recreation can benefit conservation goals while providing the public with numerous benefits. However, balancing increased demand for recreation opportunities and maintaining ecological integrity can pose difficult tradeoffs for managers. As such, there is a need for additional data-driven resources to help inform land management decisions. Traditional approaches of measuring recreational use, such as trail counters, are costly, labor intensive, and lack the...AuthorsMaksim Sergeyev, Mark Ditmer, Kira Z.

- The marbled murrelet (Brachyramphus marmoratus) is a seabird of conservation concern that nests in late-successional, old-growth forests in Oregon, Washington, and California, USA. Traditional audio-visual surveys have been the standard method for detecting murrelets in forests. Given that murrelets can be extremely cryptic in forest environments, audio-visual surveys are difficult, time consuming, and expensive to conduct. Passive acoustic monitoring (PAM) may be a useful and cost-effective alternative. Using a paired murrelet survey design, we compared detection probabilities across 88...AuthorsAlaina Thomas, Adam Duarte, Matt J. Gostin, James T. Peterson, Damon B.
