Reactions Of Organic N-Chloramines In The Gastric Fluid Of The Rat, Kathryn E. Mazina
Reactions Of Organic N-Chloramines In The Gastric Fluid Of The Rat, Kathryn E. Mazina
Chemistry & Biochemistry Theses & Dissertations
Using chlorine as a drinking water disinfectant may have potential health effects due to its reactivity with organic amino nitrogen compounds found in the stomach. Organic N-chloramines have been shown to form in the stomachs of laboratory rats. The possible reactions of N-chloramines in the stomach fluid were examined in this study using a model radiolabeled N-chloramine. 36Cl-N-Chloropiperidine, was synthesized and purified to remove 36Cl-chloride. Stomach fluid was obtained from Sprague-Dawley rats which had been first fasted for 24 or 48 hours and then administered 3 mL of deionized water. Different concentrations of radiolabeled chloramine were reacted with …

Soil Science News and Views
The "foods" used by green plants for growth and life functions are referred to as nutrients or fertilizer elements. There are 16 nutrients required for plant growth and development (See Table l). Although carbon, hydrogen, and oxygen are found in plants in the greatest quantities. they are obtained by plants from air (carbon dioxide) and water rather than from fertilizers or the soil. Of the nutrients provided by the soil or from fertilizers. those required in large amounts are called PRIMARY nutrients. Those required in smaller amounts are called SECONDARY nutrients, while those needed in very small amounts are called …

A Robust-Resistant Spatial Analysis Of Soil Water Infiltration., Noel A. Cressie, R Horton
Faculty of Informatics - Papers (Archive)
Concentrates on estimating the spatial correlations between soil water infiltration observations, with special emphasis on resistant methods to remove nonstationarity. After this removal, robust semivariogram estimators are used to examine the spatial dependencies for various tillage treatments. There is some indication that infiltration characteristics inherit different types of spatial dependency, depending on the tillage treatment applied.-from Authors
