We assessed genetic diversity, population structure, current effective population size, and demographic history of M. septentrionalis distributed across the United States to determine baseline levels pre-WNS. We analyzed RADseq data from 81 individuals from Kentucky, Louisiana, Michigan, Minnesota, North Carolina, Oklahoma, and Wisconsin. Additionally, we examined population genetic structure using discriminant analysis of principal compone...AuthorsJenna Grimshaw, Deahn Donner, Roger Perry, W Mark Ford, Alex Silvis, Carlos Garcia, Richard Stevens, David Ray, Christina DavyKeywordsSourceJournal of MammalogyYear2024
- Besides the importance of internal quality, the textural quality properties of the product have a remarkable effect on consumer satisfaction and market price. Mainly, the three-dimensional (3D) modeling technique is applied to evaluate the quality of agricultural products. This study aimed to employ the structure from motion (SFM) method along with the particle film technique to predict the physical features of tomatoes. Reconstructing 3D models of tomatoes is challenging due to their shiny skin. In this study, a new method based on particle films was developed to address this issue. Fifty sam...AuthorsMohammad Masoudi, Mahmood Reza Golzarian, Shaneka Lawson, Mohammad Rahimi, Syed Mohammed Shamsul Islam, Rasool KhodabakhshianKeywordsSourceComputers and Electronics in AgricultureYear2024
- This study conducted a detailed evaluation of the feasibility of producing cellulose microfibrils (CMF) from a kraft-bleached hardwood pulp at high solid contents with and without pretreatments. CMFs produced by planetary ball milling at solid contents 17 and 28% were compare with those from 1 to 5% under the same milling conditions. Fiber pretreatments using a commercial endoglucanase and mechanical refining using a laboratory PFI mill were also applied before ball milling at a solid content of 28%. Two mechanisms of fiber fibrillation were identified from the results obtained: (i) ball an fi...AuthorsXiaoxue Zhang, Daniel J. Yelle, Peter Kitin, Guolin Tong, J.Y. ZhuKeywordsSourceJournalYear2024
- Adhesion and agglomeration of small sticky particles, i.e., microstickies, not paper and paper machines cause serious problems for recycling mills. Because associations between materials with similar surface energies are strongest, we propose an “adhesives collect stickies” strategy to physically remove microstickies from whitewater systems. We characterized deposits from a commercial paper machine and observed a large amount of acrylate-based materials. Based on this observation, we chose to graft glycidyl methacrylate (GMA) to surfaces of polypropylene (PP) to make it more similar to the dep...AuthorsKunrui Xu, Wenxuan Mo, Fengshan Zhang, Carl Houtman, Jinquan Wan, Bo LiKeywordsSourceJournalYear2024
- Berkovich nanoindentation was used to characterize viscoelastic and viscoplastic deformations in the semicrystalline polymers, poly(ether ether ketone) (PEEK) and low density polyethylene (LDPE). The quasistatic experiments generated viscoelastic moduli over four decades in frequency and hardness over more than four decades of indentation strain rate. These semicrystalline polymer results augment analogous results previously obtained from the amorphous polymers, poly(methyl methacrylate), polycarbonate, and polystyrene. Although nanoindentation viscoelastic moduli were all systematically highe...AuthorsJoseph Jakes, Jane O’dell, Donald S. StoneKeywordsSourceJournalYear2024
- The American Pika (Ochotona princeps) has been considered a species at risk due to warming temperatures associated with climate change. Many life-history attributes of pikas contribute to the sensitivity of pikas to warming temperatures. Repeated censuses of a marginal (warm, low-elevation) population of pikas at Bodie State Historic Park, California, conducted from 1972 to 2022, are presented to track the population trajectory of pikas for a time period predating recent awareness of global warming to the present day, thus giving a comprehensive portrayal of how American pikas may be respondin...AuthorsAndrew Smith, Constance Millar, Easton White, Jennifer FreyKeywordsSourceJournal of Mammalogy. 84(1): 37Year2024
- In 2011, industrial roundwood output from the South’s forests totaled 7.17 billion cubic feet, 9 percent more than in 2009. From 2011 to 2017, industrial roundwood increased to 8.51 billion cubic feet, 19 percent. In 2017, pulpwood was the leading roundwood product at 3.80 billion cubic feet; saw logs ranked second at 3.04 billion cubic feet; bioenergy/fuelwood production was third at 554.0 million cubic feet. Between 2011 and 2017, total byproducts generated from primary manufacturers increased 23 percent to 2.59 billion cubic feet. In 2017, 99 percent of produced residues were used for anoth...AuthorsWilliam P. Durham, Larry T. CyprianKeywordsYear2024
- The effects of the antioxidant, butylated hydroxytoluene (BHT), and the metal chelator, ethylenediaminetetraacetic acid (EDTA) in combination with cedarwood oil (CWO) were investigated for wood preservation against subterranean termites as well as two species of white-rot decay fungi and two species of brown-rot decay fungi. Vacuum pressure impregnation was used to treat wood blocks. Resistance of the treated wood test blocks was evaluated using a no-choice bioassay for termites and a soil bottle assay wood decay fungi. Eight treatments were tested: H2O only; BHT only; EDTA only; BHT with EDTA...AuthorsFred J. Eller, Grant T. Kirker, Mark E. Mankowski, Gordon W. SellingKeywordsSourceJournalYear2024

- Buildings play a significant role in the rise of energy consumption and carbon emissions. Building operations are responsible for 28% of the world’s carbon emissions. It is crucial, therefore, to evaluate the environmental impact of various buildings’ operational phase in order to implement sustainable strategies for the mitigation of their energy usage and associated carbon footprint. While numerous studies have been conducted to determine the carbon footprint of conventional building operation phases, there are still a lack of actual data on the operational carbon (OC) emissions of mass timb...AuthorsMoein Hemmati, Tahar Messadi, Hongmei Gu, Mahboobeh HemmatiKeywordsSourceJournalYear2024
