—This paper presents a 28-Gb/s transceiver in 32-nm SOI CMOS technology for chip-to-chip communications over high-loss electrical channels such as backplanes. The equalization needed for such applications is provided by a 4-tap baud-spaced feed-forward equalizer (FFE) in the transmitter and a two-stage peaking amplifier and 15-tap decision-feedback(More)
Recent projections by the Northeastern Illinois Planning Commission of population growth of one million and water shortages in the Chicago metropolitan area by 2020 are a wake-up call for action. Similar analyses and projections for the rest of Illinois have not yet been made. Water is increasingly recognized as a precious renewable resource to be managed(More)

Chloride (Cl-) is a major anion found in all natural waters. It occurs naturally and is also a relatively minor contaminant. Chloride concentrations in Illinois range from less than 0.1 milligrams per liter (mg/L) in precipitation to close to 100,000 mg/L in Paleozoic brines. Chloride is non-toxic to humans, although there is a secondary drinking water(More)
The nuclear reactor from the Soviet radar reconnaissance satellite, Cosmos-1402, reentered the earth's atmosphere on 7 February 1983 and disintegrated over the South Atlantic Ocean. The reactor was powered by approximately 50 kilograms of uranium-235 ((235)U). In an effort to determine the fate of the reactor core, a series of aerosol samples were collected(More)
Many communities in the western suburbs of Chicago currently obtain water from deep Cambrian-Ordovician sandstone aquifers. These aquifers are generally covered by 100-800 ft of low permeable material (aquitards), which impedes the ability of rain water to infiltrate into the aquifers. As a result, it can take decades to replenish water withdrawn from these(More)
A procedure is presented whereby the fossil fuel community may design and mix SRMs in different proportions and thereby produce in their laboratory standards for sulfur in distillate fuel oil, residual fuel oil, and coal of almost any desired concentration with uncertainties that are calculable and traceable to NIST SRM certified values. The expanded(More)
