Effects of wood species and prior fungal exposure on the feeding habits of the dampwood termite Zootermopsis angusticollis

Creator:: Mankowski, Mark Edward
Abstract:: The effects of natural preconditioning (source wood), wood species, and previous exposure of wood to two types of fungi on the feeding rates and protozoa survival in the Pacific dampwood termite Zootermopsis angusticollis (Isoptera: Termospidae) were examined under laboratory conditions. Termites were exposed to four wood species that had been...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

The economic feasibility of preheating Douglas-fir blocks prior to peeling

Creator:: Baskin, Richard
Abstract:: Past research and industrial sources have implied that preheating Douglas-fir Pseudotsuga menziesii (Mirb.) Franco prior to peeling veneer was economically feasible. To test this, the effect of treatment temperature on veneer yield and thickness variation for three diameter classes of low grade Douglas-fir logs was studied and related to the...

Quality characteristics for fully-cooked ham, brine-cured prior to freezing

Creator:: Wilson, Vicki L.
Abstract:: Thirty bone-in hams from market weight hogs were used in this study, three groups of 10 each. One group was brine-cured, frozen and stored (F/S) at -20°C for 90 days prior to heat processing and smoking. A second group was similarly cured and frozen, not stored (F/NS), but thawed immediately,...

Low-voltage pipeline A/D converter

Creator:: Wu, Lei
Abstract:: Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...

Increasing Vitamin D Levels to Improve Fertilization Rates in Cattle

Creator:: Peixoto de Souza, Vanessa
Abstract:: Recently, an interest in supplementation of vitamin D to improve aspects of health, especially in human fertility, has emerged. However, supplementation of Vitamin D above the minimum required levels to prevent deficiency has yet to be explored in cattle despite evidence for vitamin D receptors in reproductive tissues. The objective...

Low power, high performance pseudo-static D flip-flop

Creator:: Low, Tim D.
Abstract:: Digital systems, in particular microprocessor, have recently experienced phenomena growth in performance. Both technology advancement and clever design have sustained this performance growth. As clock frequency heads into the Ghz range, new circuit design, for both logic and storage, are needed. Such new circuit technology must provide needed performance with...

D₊₊ : Structural Credit Assignment in Tightly Coupled Multiagent Domains

Creator:: Rahmattalabi, Aida
Abstract:: Autonomous multiagent teams can be used in complex exploration tasks to both expedite the exploration and improve the efficiency. However, use of multiagent systems presents additional challenges. Specifically, in domains where the agents' actions are tightly coupled, coordinating multiple agents to achieve cooperative behavior at the group level is difficult....

Adaptive correction techniques for delta-sigma A/D converters

Creator:: Abdennadher, Salem
Abstract:: Oversampling analog-to-digital and digital-to-analog converters are gaining more popularity in many signal processing applications. Delta-sigma modulators are used in practical applications of oversampling systems because of their apparent practical advantage over other oversampling converters in terms of insensitivity to the inevitable imperfection of the analog circuitry. In Δ∑ modulators, analog...

Catalytic desymmetrization of D₂d̳-symmertic proprochiral tetrasubstituted biphenyl compounds: a novel approach to the synthesis of axially chiral C₂-symmetric molecules

Creator:: Gunderson, Jeremey Tyson
Abstract:: Many D2d-symmetric 2,2',6,6'-tetrasubstituted biphenyls are readily prepared via net oxidative dimerization of appropriate 1,3-disubstituted benzenes. Conversion of such proprochiral compounds to useful C2-symmetric chiral biphenyls requires formal replacement of two substituents on opposing aryl ring units with alternate groups. This under exploited desymmetrization tactic has been demonstrated for the generation...
