We conducted a detailed investigation of U isotopes in conjunction with a broad geochemical investigation during field-scale biostimulation and desorption experiments. This investigation was carried out in the uranium-contaminated alluvial aquifer of the Rifle field research site. In this well-characterized setting, a more comprehensive understanding of U isotope geochemistry is...
A farm level comparative study was conducted to
determine the extend to which the production component of
the tomato industry of Panama is competitive with its
American producer counterparts in California. In addition,
processing costs, and marketing conditions/costs are factors
that determine a competitive potential. The objective of
this study...
This article describes the results of numerical experiments carried out with a general circulation ocean model to investigate the effect of the seasonal cycle of the wind forcing on the Agulhas transport. Two cases are described. The first was initialized with temperature and salinity values obtained by horizontally averaging Levitus...
This laboratory bioassay focused on lethal and sublethal effects of five
insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and
mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using
second instars and adult males and females. Formulated...
We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...
