Structural Dynamic Response Assessment Of Clt Wall Structure Systems In Wind-Only And Sequential Seismic–Wind Scenarios, Yunxiang Ma, Qingli Dai, Alexander Zhao
Michigan Tech Publications
Because of concentrated connection damage, the impact of sequential hazards on CLT shear wall systems is much more severe than that on traditional concrete and steel structures considering ductile component behaviors. The present paper evaluated the dynamic response of CLT wall structures in wind-only and sequential seismic–wind scenarios and compared the structural dynamic responses and damage levels of different CLT wall systems. The structural models were established separately based on an SOM benchmark structure, a SOFIE project three-story CLT shear wall structure, and a PT CLT wall platform structure from the NHERI Tall Wood project. The equivalent fluctuating wind load …

“Blue Rings” In Engelmann Spruce From The Greater Yellowstone Ecoregion: Their Presentation And Efficacy As Proxies For Ephemeral Cooling Events, Isaac Grimm, Maegen Rochner
The Cardinal Edge
As the polar jet stream’s activity transforms under climate change’s influence, short-term, or ephemeral, cooling events could become more frequent. Understanding how such cooling events may affect forest dynamics and tree-growth can allow us to predict how the morphing jet stream may reflect in our future forests. “Blue rings” (BRs) have presented themselves as subsections of annual rings, made clear through the double-staining of microsections of wood, which have been associated with the interruption of conifers’ lignification process. Such features could allow us to peer back into pre-instrumental records and assess how a tree’s growth and their surrounding canopy may …

Leaf Droppage Delayed In Sugar Maple Trees On An Urban To Rural Gradient, Isabella S. Bastien, Isabella Bastien
The Cardinal Edge
This study investigates the timing of leaf abscission in Sugar Maple (Acer saccharum) trees along an urban-to-rural gradient in Louisville, Kentucky, to determine how proximity to urban environments influences leaf drop. We hypothesized that urban trees would retain their leaves longer than suburban or rural trees due to environmental stressors and tested this using weekly leaf collection and canopy cover measurements from three locations—urban, suburban, and rural. Results showed that urban trees exhibited delayed leaf drop and slower canopy opening compared to suburban and rural trees. These findings suggest that urban stressors significantly alter tree phenology, which may signal underlying …

This study unravelled the intricacy of bio-based hydrophobic formulae as a substitute for the conventional emulsified paraffin wax (hydrowax), a hydrophobic additive currently utilised in high-density fibreboard (HDF) fabrication. Utilisation of hydrowax is not a sustainable practice due to the potential depletion of its fossil-based sources. The industrial acceptability of a renewable hydrophobic additive depends on several stages of trials. Therefore, through a pilot-scale trial, this study explored the substitution effect of bio-based tall oil distillation product (TODP) in the HDF panels, establishing its mechanical and water-related properties. While the mechanical properties of the panels were not primarily influenced by …

Trees can redirect large volumes of rainwater to the base of their stems. This stemflow not only redistributes water but also channels canopy-derived solutes to the forest floor. Building on research showing canopy geometry and bark properties govern stemflow volumes, we examined how those same traits modulate the biogeochemical side of this flux. Over a 12-month period in Jamari National Forest (Brazil), we quantified stemflow volume and solute chemistry for 19 trees grouped by diameter at breast height (D: < 10, 10-20 and > 20 cm), crown area (CA: < 30, 30-60 and > 60 m(2)) and bark texture (smooth, fissured and rough). Small-stemmed, smooth-barked trees produced the greatest stemflow …

Coyotes (Canis latrans) expanded across eastern North America in the last century and are ecological generalists capable of thriving across diverse habitats. Broad genetic surveillance has reported little spatial genetic patterning for this highly dispersive species. Here, we explore the genome-wide signatures of spatial patterns found in a 10-year study of 1199 coyotes from northeastern United States, with a temporal analysis of Pennsylvania coyotes. Despite their broad dispersal capability, we detected subtle but significant population structure, with two genetic clusters that have a weak clinal transition zone. This partitioning aligned qualitatively with patterns of human population density and activity. We …

Functional Characteristics Of Ice Creams Enriched With Aronia Melanocarpa And Sambucus Nigra L. Extracts, Murat Emre Terzi̇oğlu, Emi̇ne Maci̇t
Turkish Journal of Agriculture and Forestry
In this study, the effects of Aronia melanocarpa and Sambucus nigra L. extracts added at different concentrations (0.5%, 1%,and 1.5%) on the physicochemical, sensory, microbiological, antioxidant capacity (DPPH• and ABTS•+ radical scavenging activity, TPC,TFC, and TAC) antidiabetic (α-amylase and α-glucosidase inhibition), and anti-Alzheimer properties (AChE inhibitory activity) of icecream were investigated. According to the statistical analysis results, extract addition did not have an effect on the total dry matter, fatand ash ratios of the ice cream samples (p > 0.05), but it had an effect on the protein ratio, viscosity, and first drip time at the level ofp < 0.05. The addition of extract positively affected the DPPH• radical scavenging activity IC50 and ABTS•+ radical scavenging activityIC50 values of the ice cream samples, and also increased the TPC, TFC, and TAC values. Indeed, a decrease in the IC50 values of DPPH•and ABTS•+ radical scavenging activities indicates an increase in antioxidant activity. The highest TPC, TFC, and TAC values weredetected in the A-1.5 sample (sample containing 1.5% A. melanocarpa extract) as 749.33 mg GA/kg, 434.70 mg QE/kg, and 290.97 mg/kg, respectively. Similarly, the highest α-amylase inhibitory activity (23.08%), the highest α-glucosidase inhibitory activity (10.41%) andthe highest AChE inhibitory activity (14.70%) were observed in the A-1.5 sample. Extract addition had no effect on microbiologicalproperties and sensory properties except texture. The results of this study showed that A. melanocarpa, S. nigra L. extracts can be usedas a natural additive with antioxidant, antidiabetic and anti-Alzheimer activities in ice cream production.

Sustainably grown feedstocks for bioenergy and bioproducts are important tools to fight climate change, provide ecosystem services, and sequester carbon. Populus species including hybrid poplars have been utilized around the world, and in the southeastern US native eastern cottonwood (P. deltoides) is often favored due to its resistance to stem cankers. However, P. deltoides has historically been grown in single stem production and its relative performance in short rotation coppice production, prevalent in Europe, is not well documented. Therefore, this study’s goals were to evaluate eastern cottonwood and hybrid poplar productivity under a two-year establishment and two-year coppice …
