Pesticide contamination inside farm and nonfarm homes.
Twenty-five farm (F) households and 25 nonfarm (NF) households in Iowa were enrolled in a study investigating agricultural pesticide contamination inside homes. Air, surface wipe, and dust samples were collected. Samples from 39 homes (20 F and 19 NF) were analyzed for atrazine, metolachlor, acetochlor, alachlor, and chlorpyrifos. Samples from 11 homes (5 F and 6 NF) were analyzed for glyphosat...
متن کاملConsideration of Water Productivity for Farm Water Management in Different Conditions of Water Availability for Dominant Summer Crops
ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...
متن کاملAlley CATs in search of good homes
A score sequence of a tournament is a monotonically non-decreasing sequence of the out-degrees of its vertices. We develop two algorithms that generates all score sequences, each of which appears to use only a constant amount of computation per sequence produced. A degree sequence of a graph is a monotonically non-increasing sequence of the degrees of its vertices. We develop an algorithm that ...
متن کاملPerspective: How good is DFT for water?
Kohn-Sham density functional theory (DFT) has become established as an indispensable tool for investigating aqueous systems of all kinds, including those important in chemistry, surface science, biology, and the earth sciences. Nevertheless, many widely used approximations for the exchange-correlation (XC) functional describe the properties of pure water systems with an accuracy that is not ful...
