Relationship between incipient decay, strength, and chemical composition of Douglas-fir heartwood

Creator:: Winandy, Jerrold E. and Morrell, Jeffrey J.
Abstract:: A new laboratory technique to simulate the initiation of wood decay and to assess the effects of incipient decay on material properties is described. Douglas-fir heartwood specimens were exposed to brown-rot (Postia placenta and Gloeophyllum trabeum) fungi for various periods. Bendlng properties were determined by nondestructive and destructive tests, and...

Effects of incising on lumber strength and stiffness: Relationships between incision density and depth, species, and MSR grade

Creator:: Winandy, Jerrold E. and Morrell, Jeffrey J.
Abstract:: This report describes the relationship of incising-induced strength loss in bending as a function of preservative treatment and incising pattern, density, and depth of penetration for various machine stress-rated (MSR) grades of full-size 2 by 4 Douglas-fir, Hem-Fir, and Spruce-Pine-Fir (South) dimension lumber. This study may represent a worst-case "incising...

Effect of incising and preservative treatment on shear strength of nominal 2-inch lumber

Creator:: Morrell, Jeffrey J., Gupta, Rakesh, Winandy, Jerrold E., and Riyanto, Djoko S.
Abstract:: This study evaluated the effects of pretreatment incising of dry lumber and preservative treatment on the shear strength of 1980 pieces of 2 X 4 dimension lumber (nominal 50 mm X 100 mm X 3.6 m long). Three species groups (Douglas-fir, Hem-Fir. and Spruce-Pine-Fir-South) and two commercially produced machine-stress-rated grades...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...

Linda, tuple spaces and its implementation on a network of Unix workstations

Creator:: Cherala, Janakiram
Abstract:: In this paper we outline an implementation of Linda on a network of Unix workstations. A literature survey was done to gain a better perspective on state of the art and to learn from the experiences of other implementations. The tuple space which is central to the Linda system is...

Peavy Arboretum : an archaeological and historical investigation of a Willamette Valley landscape

Creator:: Hylton, Lindon B.
Abstract:: This thesis documents a period of ecological and cultural change on a Willamette Valley, Oregon landscape. In particular, this study examines the Peavy Arboretum area and the cultural changes that accompanied the transformation of the landscape from an oak savannah in the mid-nineteenth century to a dense Douglas-fir forest in...

Design and implementation of a heuristic-based decision support system for nurse scheduling

Creator:: Sitompul, Darwin
Abstract:: A decision support system (DSS) for nurse scheduling in hospitals is developed and implemented on microcomputer. The system includes algorithms and databases for developing weekly work and shift patterns and combining these into working schedules for nurses for a specified time horizon, and interface modules for the user to interact...

A study to determine the media competencies recommended by inservice teachers from specific teaching disciplines

Creator:: Jensen, Edward A.
Abstract:: This study was an investigation to determine the instructional media competencies that inservice teachers of secondary education teaching disciplines recommend for pre-service teachers in their discipline. A literature review focused on four main questions: 1. What historical events mark the development of the field of instructional media? 2. What are...
