This paper discusses the historical geographical construction of a contaminated community in the heart of one of the largest and fastest growing Sunbelt cities in the US. Our focus is on how racial categories and attendant social relations were constructed by Whites, in late 19th and early 20th century Phoenix, Arizona, to produce a stigmatized zone of racial exclusion and economic marginality ...

Phoenix Services, Inc., owns and operates the Baltimore Regional Medical Waste Incinerator in Baltimore, MD. New regulations for dioxins and furans imposed a limit that was considerably below historical emission levels. To determine a method to comply with the new dioxin/furan regulations, Phoenix Services performed trials with powdered activated carbon (PAC). Although the results with carbon w...

[1] We studied the low-temperature properties of sodium and magnesium perchlorate solutions as potential liquid brines at the Phoenix landing site. We determined their theoretical eutectic values to be 236 ± 1 K for 52 wt% sodium perchlorate and 206 ± 1 K for 44.0 wt% magnesium perchlorate. Evaporation rates of solutions at various concentrations were measured under martian conditions, and rang...

The Local Group galaxy Phoenix has the properties of a dwarf spheroidal galaxy, but an adjacent HI cloud has been recently found to be at the same radial velocity as the stars. The proximity suggests that this cloud is associated with the most recent (≤ 100 Myr) star formation in Phoenix. We have obtained relatively high sensitivity and high resolution HI imaging with the VLA with the goal of d...

INTRODUCTION Oxidative stress is a key factor involved in male infertility, which is due to an unnatural increase in environmental free radicals. In the majority of cases, this has a negative effect on a male's ability to impregnate a female. Currently, it is believed that spermatozoa can be protected against the damages induced by oxidative stress by saturating sperm with antioxidants. The ant...
