A mathematical model of a hydrogen/oxygen alkaline fuel cell
(1991)
A mathematical model of a hydrogen/oxygen alkaline fuel cell is presented that can be used to predict the polarization behavior under various power loads. The major limitations to achieving high power densities are indicated ...
Use of hydrothermal methods for the synthesis of metal molybdates, copper carboxylates and molybdenum phosphates
(1990)
In this work, hydrothermal reactions were studied as a synthetic method in three systems: metal molybdates, copper carboxylates and molybdenum phosphates. Different solvents were used in each system studied to determine ...
Non-invasive, objective measurement of intramuscular fat in beef through ultrasonic A-mode and frequency analysis
(1991)
A noninvasive, objective measurement method for predicting intramuscular fat concentration in beef through ultrasonic A-mode and frequency analysis was developed. Ultrasonic longitudinal and shear speed were evaluated for ...
America's back door : indirect international immigration via Mexico to the United States from 1875 to 1940
(1992)
Mexico provided many opportunities for indirect international immigration to the United States between the years 1876 and 1940. The immigrants traveled from their countries of birth, for example China, Japan, Eastern Europe, ...
Fate of (14C)xanthotoxin (8-methoxypsoralen) in laying hens and lactating goats
(1990)
The metabolism of xanthotoxin, a naturally-occurring furanocoumarin photosensitizer, was studied in laying hens and lactating goats treated with a single oral dose equivalent to 10 mg xanthotoxin/kg of body weight. Within ...
The chemical generation of superoxide ion, and its relative reactivity (versus hydroperoxide ion and hydroxide ion) with halocarbons, esters, and nitriles in aprotic media
(1990)
With dioxygen-saturated (1 atm, 2.1 mM) dimethyl sulfoxide solutions that contain aniline (1-15 mM), the addition of excess hydroxide ion (10:1 HO-/PhNH2) yields approximately two superoxide ions (O2-), one azobenzene, and ...
The effect of bureaucratic structure on individual contributions to a public good
(1991)
The effect of bureaucratic structure on individual contributions to a public good is examined using a laboratory experiment. It is proposed that when individuals are placed in the context of an ideal-typical bureaucracy ...
High mass diffractive dissociation at 27.5 GeV proton-proton interactions in exclusive final states
(1990)
A study of diffractive production in 27.5GeV/c proton-proton interactions is presented. The detector that was used to take the data and the techniques that were used to analyze the data are also discussed. The results are ...
Immunotoxic effects of polychlorinated diphenyl ethers, biphenyls and dibenzofurans : quantitative structure-activity relationships and role of the Ah receptor
(1992)
The role of the aryl hydrocarbon (Ah) receptor in mediating the immunotoxic effects of several polychlorinated diphenyl ethers (PCDEs), polychlorinated biphenyls (PCBs), and alkyl-substituted polychlorinated dibenzofurans ...
The role of organic matter alteration in sediment diagenesis : the Delaware Mountain Group of west Texas and southeast New Mexico
(1992)
Aqueous species derived from first-order degradative reaction of organic matter can modify Eh and pH conditions in the burial environment and regulate solubility characteristics of other aqueous species and minerals in the ...
