Assessment of three large-scale depopulation methods for swine.

open access: yesPLoS ONE
The threat of foreign animal disease outbreaks to U.S. swine herds warrants effective and readily available depopulation methods. Current American Veterinary Medical Association-recommendations using preferred physical methods for swine depopulation are ...

Measuring nitrogen loss from denitrification

open access: yesCalifornia Agriculture, 1977
Denitrification is the biological reduction of nitrate and nitrite to volatile gases, usually nitrous oxide or molecular nitrogen, or both. Denitrification is accomplished by bacteria capable of using nitrate in place of oxygen.

Enthalpies of dissociation of clathrate hydrates of carbon dioxide, nitrogen, (carbon dioxide+ nitrogen), and (carbon dioxide + nitrogen+ tetrahydrofuran)

Journal of Chemical Thermodynamics, 2001
Abstract A calorimetric technique is described for measuring the enthalpy of dissociation liberated from solid hydrates. In this study, the enthalpies of dissociation were determined at T =  273.65 K andp =  0.1 MPa for simple and mixed hydrates of carbon dioxide, nitrogen, (carbon dioxide  +  nitrogen), and (carbon dioxide  +  nitrogen ...

The Pathobiochemistry of Nitrogen Dioxide

Biological Chemistry, 2002
Nitrogen dioxide (*NO2) is an oxidizing free radical which can initiate a variety of destructive pathways in living systems, and several diseases are suspected to be connected with both exogenously and endogenously formed *NO2. Peroxynitrite (ONOO-/ONOOH) is believed to be an important endogenous source of *NO2 radicals, but other sources, among them ...

Respiratory responses to nitrogen dioxide inhalation subtitle: Nitrogen dioxide

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1984
An investigation was made of the effects of nitrogen dioxide (NO/sub 2/), a combustion-related pollutant reported to depress host resistance to infection, on respiratory patterns in the mouse. Control mice were exposed to filtered air for 3 days; experimental mice were exposed to 5 ppm NO/sub 2/ for the same number of days. After exposure, both control
