Adoption of Conservation-Tillage Practices and Herbicide-Resistant Seed in Cotton Production
(AgBioForum, 2009)
Agricultural Resource Management Survey data for 2003 were used to estimate logit models for adoption of conservation-tillage practices and herbicide resistant/ stacked-gene cottonseed in the United States. The specification ...
Geographic Differences in Semen Quality of Fertile U.S. Males
(Environmental Health Perspectives, 2003-04)
partners of 512 pregnant women recruited through prenatal clinics in four U.S. cities during 1999-2001; 91% of men provided two specimens. Sperm concentration, semen volume, and motility were determined at the centers, and morphology was assessed at a...

(University of Missouri, College of Agriculture, Food and Natural Resources, 2022)
The study used Mann Kendall's and Sen's slope tests to elicit rice farmers' perceptions of climate change due to extreme weather occurrences and compared them to hydro-meteorological data. According to the findings, ...
The Effect of Stellar Evolution on SiC Dust Grain Sizes
(American Astronomical Society, 2005)
Stars on the asymptotic giant branch (AGB) produce dust in their circumstellar shells. The nature of the dust-forming environment is influenced by the evolution of the stars, in terms of both chemistry and density, leading ...
Chaos in the Kepler system
(American Institute of Physics, 1999)
The long-term dynamical evolution of a Keplerian binary orbit due to the emission and absorption of gravitational radiation is investigated. This work extends our previous results on transient chaos in the planar case to ...
