Measuring population pressure on the landscape: comparative GIS studies in China, India, and the United States

Autor: David Rain, John F. Long, Michael R. Ratcliffe

Publikováno v: Population and Environment. 28:321-336

Measures of the effects of population pressure on the landscape using traditional methods for classifying urban territory are inadequate. The crude scale at which population densities are calculated and dependence on country-specific administration d

Comparison of Ultrastructural Cytotoxic Effects of Carbon and Carbon/Iron Particulates on Human Monocyte-Derived Macrophages

Autor: Robert L. Kristovich, John F. Long, Marshall V. Williams, W. James Waldman, Prabir K. Dutta, Deborah A. Knight

Publikováno v: Environmental Health Perspectives

In this study, we tested the hypothesis that the presence of iron in carbon particulates enhances ultrastructural perturbation in human monocyte-derived macrophages (MDMs) after phagocytosis. We used 1-microm synthetic carbon-based particulates, desi

Analysis of the biological and chemical reactivity of zeolite-based aluminosilicate fibers and particulates

Autor: W. James Waldman, Richard K. Meister, Marshall V. Williams, Prabir K. Dutta, John F. Long, Estelle Fach

Publikováno v: Environmental Health Perspectives

Environmental and/or occupational exposure to minerals, metals, and fibers can cause lung diseases that may develop years after exposure to the agents. The presence of toxic fibers such as asbestos in the environment plus the continuing development o

Discriminating Audience Donor Factors for Public Radio: A Tale of Two Cities

Autor: Paul J. Traudt, John F. Long

Publikováno v: Journal of Media Economics. 12:51-66

This study seeks to elucidate some of the key variables determining donor levels to public radio. Results from two markets indicate that demographics, program preferences, and community outreach impacted monetary contribution. Analysis of a medium-si

Fluorescence imaging of reactive oxygen metabolites generated in single macrophage cells (NR8383) upon phagocytosis of natural zeolite (erionite) fibers

Autor: Brian D. Hogg, John F. Long, Prabir K. Dutta

Publikováno v: Environmental Health Perspectives
Scopus-Elsevier

In this paper we address the phenomenon of reactive oxygen metabolite generation subsequent to phagocytosis of mineral fibers by macrophages. Natural erionite fibers were chosen because of their established toxicity. Macrophages (cell line NR8383) we
