In the rabbit model of syphilis, infection phenotypes associated with the Nichols and Chicago strains of Treponema pallidum (T. pallidum), though similar, are not identical. Between these strains, significant differences are found in expression of, and antibody responses to some candidate virulence factors, suggesting the existence of functional genetic differences...
Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...
Perennial ryegrass (Lolium perenne L.) is a widely grown cool season, bunch type, short lived perennial grass that is native to Europe, Asia, and North Africa, but has been adapted globally. Perennial ryegrass is quick to establish, has a long growing season, and produces high seed yield and forage or...
The National Park Service initiated a backcountry campsite restoration project
in 1987 to restore native vegetation on severely degraded campsites in three subalpine
lake basins in Yosemite National Park. Restoration treatments included soil
scarification, transplanting, manual seeding and site protection. Eight of the treated
campsites were monitored in 1990 to...
The major purpose of this study was to develop an Adaptation
Model for emergency departments in urban and suburban Health
Maintenance Organizations. Questions explored which provided data
for the Model were: 1) are there significant differences in the
demographic, sociologic, and decision-making characteristics of
clients seeking services in emergency rooms...
The purpose of the research project was to teach the management
of perpetual and periodic inventory systems to university students in
the field of food systems management through the use of a microcomputer
software program developed for this purpose. The objective
of the study was to determine the classroom simulation's...

In your knitting project you will be learning a very old skill that dates back as far as 200 A.D. As you progress through the different phases, you will have an opportunity to use many kinds of yarn and designs.
In the 4-H knitting project you can learn to:
•...
Agricultural water supplies are becoming increasingly uncertain in the western United States due to rising demand from competing water users, environmental restrictions on surface water withdrawals due to water quality and endangered species concerns, and, potentially, climate-induced hydrological changes. Since many rural areas in the West depend economically upon irrigated...
