A bench scale PVD remediation system experiment.

Prefabricated vertical drains (PVDs) have been used for decades for soil improvement. Recent research has shown that PVDs can also be used to remediate contaminated fine-grained soils. A research program was undertaken at The University of Texas at Austin to study the use of PVDs in soil flushing (pump and treat).

Resources for individual and team growth.

A selected annotated bibliography for parish nurses, health care chaplains, and community clergy is presented. The last section provides references to materials that speak to specific opportunities for ministry that interest these professionals, including aging, bereavement, the sick, counseling for emotional support, and domestic violence.

A labetalol metabolite with analytical characteristics resembling amphetamines.

A metabolite of labetalol that is responsible for previous reports of false-positive assays for amphetamines by thin-layer chromatography and immunoassay has been identified. The compound, 3-amino-1-phenylbutane (APB), an oxidative metabolite of labetalol, was initially identified in a patient's urine by gas chromatography-mass spectrometry and confirmed by analysis of the pure material. Gas chromatography showed a single major peak with relative retention time indistinguishable from that of methamphetamine, both underivatized and as the pentafluoropropionyl derivative.
