Ripening tomatoes are a familiar sight in Pacific Northwest gardens and fields during the late summer months. Because the storage life of fresh tomatoes is limited, many households preserve them for year-round enjoyment. Home canning is one of the most popular preservation methods.
When canning tomatoes and tomato products, safe...
Mealybugs, a family of soft, oval-bodied pests (Homoptera: Pseudococcidae), are known vectors (carriers) of the grapevine leafroll associated viruses (GLRaVs) of grape. This document gives details on how pheromone traps should be used to ensure optimal catches and early detection.
The Oregon State University Extension Service Master Gardener Program is a voluntary educational
program designed to meet the community’s gardening needs. This publication provides an introduction to the program and the Master Gardener position.

Gray mold, one of the most serious decay problems for pear fruit in the Pacific Northwest, is estimated to cause about $6 million in losses to the pear industry each year due to fruit rot in storage. These losses can be minimized by recognizing the factors that contribute to disease...
We study the stability properties of, and the phase error present in, several higher order (in space) staggered finite difference schemes for Maxwell's equations coupled with a Debye or Lorentz polarization model. We present a novel expansion of the symbol of finite difference approximations, of arbitrary (even) order, of the...
Meat from big game animals (such as deer, antelope, elk, moose, and bear) is a nutritious choice for family meals. You'll enjoy eating it when it's good quality and well-prepared. For best flavor, it's important to handle game carcasses carefully and to butcher and store the meat correctly. This publication...

A succinct description of cultural practices for commercial cranberry production in Oregon, visually organized by growth stage throughout the year, from post-harvest through the following harvest.
Modern day digital systems employ frequency
synthesizers to provide a common clock to the system.
They are undergoing large scale integration due to which, mitigation
of the effect of noise on power supply has become a major design consideration
in clocking circuits. Rapid scaling of CMOS technology mandates the
design...
Oxytocin is a hormone well know for the stimulation of childbirth and milk letdown in mammals. Large levels of the hormone are also released during angiogenesis in the growth of the corpus luteum (CL), a temporary endocrine gland that forms on the ovaries following ovulation. Levels of oxytocin decline after...
Azaspiracid has generated an enormous amount of scientific interest in the fourteen years since its initial discovery. The structure contains a 6,5,6 bis-spiroketal, a [3.3.1] bicyclic ketal and a 6,5-spiroaminal linkage as key moieties. With 9 rings, 20 stereocenters and three alkenes, the azaspiracid immediately attracted the interest of the...
The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...
This dissertation presents an incremental analog-to-digital converter (ADC) with digital digital-to-analog converter (DAC) mismatch correction. A theoretical time-domain analysis technique was developed to predict the noise performance of the incremental ADC, and a new optimization technique was proposed to minimize the output noise.
In the calibration mode, the incremental ADC...
The objective of this thesis is to provide an initial demonstration of two-terminal and three-terminal electronic devices employing amorphous multi-component metallic film
(AMMF) electrodes. Such a demonstration is successfully achieved in the fabrication of metal-insulator-metal (MIM) diode and hot electron transistor (HETs) structures employing ZrCuAlNi AMMF electrodes. The ultra-smooth surface...
This study examines the impact of two decades of neoliberal policy reform on food production and household livelihood security in three West African countries. The rice sectors in The Gambia, Côte d’Ivoire, and Mali are scrutinized as well as cotton and its relationship to sorghum production in Mali. Although market...
In June 2009, LAMP appointed a task force to develop a circulating Amazon Kindle program. In November 2009, five Kindle e-book readers were placed in circulation. This report describes the questions addressed, decisions made, and the circulating program as it is currently configured.
