Improving the durability of second growth timbers of naturally durable species

Creator:: Cabrera Orozco, Yohanna
Abstract:: While the heartwood of many wood species exhibits excellent resistance to fungal and insect attack, this resistance is sometimes diminished in second-growth material of the same species. The reasons for the reduced durability are unclear, but they may reflect a combination of both higher proportions of sapwood as well as...

Effects of biocide treatment on durability and fungal colonization of teak, western redcedar, and redwood

Creator:: Cabrera Orozco, Yohanna
Abstract:: Treating durable, second-growth or plantation-grown material with supplemental chemicals could improve durability while enhancing the uniformity of the products. To test this hypothesis, the effect of two candidate biocide treatments on the durability of teak, redwood, and western redcedar was assessed in a ground proximity field test established in Hawaii....

Effect of wood moisture content and rod dosage on boron or fluoride movement through Douglas-fir heartwood

Creator:: Cabrera, Yohanna and Morrell, J.J.
Abstract:: The potential for moisture sorption by boron and fluoride rods following application of rods to wood to affect subsequent chemical diffusion was investigated in small Douglas-fir blocks conditioned to 30, 60, or 90 percent target moisture content (MC). MCs tended to decline over the 180-day test period, but there was...

Parental beliefs and practices : influences of parenting in Latino/a and Caucasian children's behavioral regulation

Creator:: Diaz, Guadalupe
Abstract:: The transition to kindergarten can be challenging for many children who do not have the necessary skills to meet the demands of classroom settings such as paying attention, remembering instructions, and demonstrating self-control. Children who lack the necessary behavioral regulation skills to meet the demands in the classroom environment are...

Adjustments and challenges experienced by adult Hispanic students in a public technical college

Creator:: Suchite, Jose M.
Abstract:: Little research has been done in the area of adult Hispanics' transition to college, a complex and challenging process which marks a critical period in their lives. Research suggests adaptation difficulty may cause them to drop out of school usually before completion of the first terms. There is a lack...

Differentiation of Positive and Negative Developmental Outcomes Among Immigrant Youth: Examining Specificity

Creator:: Olsen, Svea G.
Abstract:: Researchers and practitioners often assume that positive and negative outcomes are inversely correlated. Youth development can be more complex than a simple linear association, however. This complexity is poorly understood, with more research needed to inform how such associations manifest among specific populations and how sociodemographic factors may drive variation...

Evaluation of transgenes for stress tolerance, lignin modification, and growth enhancement in poplar

Creator:: Elias, Ani Anna
Abstract:: We evaluated genes previously identified from a large scale functional genomics screen for their potential value to help enhance carbon sequestration in planted trees. We used poplar as a model tree species because of its abundant genetic variation, ease of gene transfer, and availability of large databases for genomic, anatomical,...

Hypercarnivorous apex predator could provide ecosystem services by dispersing seeds

Creator:: Sarasola, José Hernán, Zanón-Martínez, Juan Ignacio, Costán, Andrea Silvina, and Ripple, William J.
Abstract:: Large “hypercarnivorous” felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation. Here we show that cougars (Puma concolor), one of the largest and the most widely ranging apex felid predators with a strictly carnivorous diet,...

Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

Creator:: Torres-Andrade, Paola A.
Abstract:: Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...
