A changing raw material supply and smaller, generally lower quality peeler logs,
are causing surface characteristics in veneer that can adversely affect glue-bond
performance. When lower quality logs are peeled, rougher veneer is usually produced.
The typical response by plywood manufacturers is to increase adhesive spread when
using rough veneer....
The Pacific Northwest region of the United States is known for quality production of blueberries, blackberries, and red raspberries. However, as the climate shifts to warmer, drier, and more extreme summers, growing these water intensive berry crops is becoming increasingly difficult. Furthermore, water regulations within agriculture are becoming more prevalent...
Stream water quality, including stream temperature, has become an increasingly important issue in recent years. Warming streams can harm aquatic ecosystems by pushing fish from traditional breading grounds, forcing them to migrate, adapt, or perish. Recent research from Scripps Institute of Oceanography at UC San Diego has shown that climate...
Feline injection site sarcomas (FISS) are frequently encountered cutaneous and subcutaneous neoplasms of cats. Significant patient morbidity is related to the invasiveness these tumors display, typically requiring extensive local excision or amputation. As with many veterinary tumors, survival time and tumor recurrence for FISS is highly influenced by histologic margin...
Microscale X-ray computed tomography (XCT) is discussed as a technique for identifying 3D adhesive distribution in wood-adhesive bondlines. Visualization and material segmentation of the adhesives from the surrounding cellular structures require sufficient gray-scale contrast in the reconstructed XCT data. Commercial wood-adhesive polymers have similar chemical characteristics and density to wood...
Complex symbioses between animal or plant hosts and their associated microbiotas can involve thousands of species and millions of genes. Because of the number of interacting partners, it is often impractical to study all organisms or genes in these host-microbe symbioses individually. Yet new phylogenetic predictive methods can use the...
In a population of the European common toad Bufo bufo from a rural pond in the region of Lake Glubokoe Regional Reserve in Moscow province, Russia, unexplained mass mortality events involving larvae and metamorphs have been observed over a monitoring period of >20 yr. We tested toads from this and...
A phenol formaldehyde (PF) adhesive was uniformly tagged with iodine such that it yielded sufficient x-ray computed tomography (XCT) gray-scale contrast for material segmentation in reconstructed wood-composite bondlines. Typically, untagged adhesives are organic and have a similar solid state density as wood cell-walls, and therefore cannot be segmented quantitatively in...
