Microcomputers are being used in teaching and learning
mathematics. This paper examines ways that computers can be used
to enhance teaching in precalculus mathematics. The advantages of
computers discussed are: 1) instant access to graphs, 2) examples
that are not oversimplified to make computations manageable, 3)
encouragement of hypothesizing and...
California's Central Valley agricultural landscapes provide several important wintering regions for Pacific Flyway sandhill crane (Grus canadensis) populations; however, the value of those regions is being compromised by urban expansion, other developments, and conversions to incompatible crop types. Greater (G. c. tabida) and lesser sandhill cranes (G. c. canadensis) both...
Production of calcium chloride (CaCl2) and aqueous ammonia (NH4 +) from the ammonia chloride (NH4Cl) stream in the Solvay process was studied using an Ammonia Recovery Tower to produce 29 wt % aqueous ammonia and 40 wt % CaCl2 from the process feed stream or the tower bottoms stream. OLI,...
I developed a priori hypotheses and used logistic regression to model Greater Sandhill
Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...
Research was conducted near the Starkey Experimental Forest and Range in
northeastern Oregon. Effects of defoliating bluebunch wheatgrass (Agropyron
spicatum (Pursh) Scribn. and Smith) to increase the quality of regrowth available on
elk (Cervus elaphus nelsoni) winter range were studied from 1988 through 1990.
Clipping treatments were implemented to condition...
There has been serious interest in hydrogen as a source of energy in the United States due to its capability of delivering a sustainable, carbon-free energy future. Currently, most hydrogen in the United States is produced via the steam methane reforming of natural gas, which converts methane to hydrogen through...
Drunk driving continues to be a national, state, and
local problem in spite of recent changes in laws governing
drinking and driving. Driving under the influence of
intoxicants (DDII) has been judged to be responsible for
approximately one-half of all traffic related deaths
nationally, killing 25,000 Americans and injuring 700,000...
There is little current research in reading instruction for gifted learners. Children who are identified as gifted in reading are often left to their own devices or provided inadequate reading/literacy instruction (Ries et al., 2004). The purpose of this project was to determine how parents of gifted children and gifted...
With Alzheimer’s disease being the most prominent form of dementia, finding potential treatments for the disease is imperative. This study explored the non-steroidal anti-inflammatory drug ibuprofen as a potential treatment to normalize the hyperactive N-methyl-d-aspartate receptor (NMDAR) within the 5xFAD mice early in the disease pathology before cognitive decline. Female...
School counselors have potential to make significant gains in closing the achievement gap for all students as advocated for by the American School Counseling Association. School counseling is moving away from the no-model model of services delivery that places counselors at the whim of principals, parents and teachers who traditionally...
