The Telecommunications Act of 1996 and Viewshed Protection for the National Scenic Trails

This Article explores the effects of the Telecommunications Act of 1996 on the viewshed of the National Scenic Trails, concentrating geographically on placement of wireless technology along the Appalachian Trail. After outlining the Act\u27s legislative history and identifying the values Congress intended to protect with its legislation, the author analyzes the conflicts between the Act and the mission of the National Park Service. As possible solutions to this tension, the author offers legal theories for protecting the National Scenic Trails, including application of the National Park Service Organic Act, the Property Clause of the United States Constitution, the National Environmental Policy Act, the Endangered Species Act, and the Migratory Bird Treaty Act. Ultimately, the Author asserts that although sponsors of the legislation creating the National Scenic Trails could not foresee the impact technological advancement would have upon the trails, today\u27s National Park Service and legislators have an affirmative duty to protect the park system from the encroachment allowed under the Telecommunications Act of 1996

Forensic NAPL Determination And Plume Differentiation – A Case Study

Recent developments in laboratory analytical techniques, when combined with application of multivariate statistical analyses allow differentiation and delineation of comingled NAPLs and resultant contaminant plumes. The increase in laboratory expertise and a growing body of relevant studies in case literature have made possible evaluation of petroleum impacted media through relatively standard techniques a reality, and well within the realm of economical site assessments. The application of several methods to determine the number, type, and timing of multiple NAPL releases at a commercial facility in an urban setting will be summarized. The combination of chemical, historical, and statistical techniques has allowed for a more complete evaluation of NAPL sources and release histories than was initially thought possible. In the examined case, overlapping NAPL plumes are defined, delineated, and identified; and source identifications for individual releases are completed. These evaluations resulted in identification of previously unconfirmed sources, improved characterization of the nature of NAPL present, and refined fate, transport, and feasibility evaluations for the conceptual site model

Renal denervation in heart failure with preserved ejection fraction (RDT-PEF): a randomized controlled trial

Aim: Heart failure with preserved ejection fraction (HFpEF) is associated with increased sympathetic nervous system (SNS) tone. Attenuating the SNS with renal denervation (RDT) might be helpful and there are no data currently in humans with HFpEF. Methods and results: In this single-centre, randomized, open-controlled study we included 25 patients with HFpEF [preserved left ventricular (LV) ejection fraction, left atrial (LA) dilatation or LV hypertrophy and raised B-type natriuretic peptide (BNP) or echocardiographic assessment of filling pressures]. Patients were randomized (2:1) to RDT with the Symplicity™ catheter or continuing medical therapy. The primary success criterion was not met in that there were no differences between groups at 12 months for Minnesota Living with Heart Failure Questionnaire score, peak oxygen uptake (VO2) on exercise, BNP, E/e′, LA volume index or LV mass index. A greater proportion of patients improved at 3 months in the RDT group with respect to VO2 peak (56% vs. 13%, P = 0.025) and E/e′ (31% vs. 13%, P = 0.04). Change in estimated glomerular filtration rate was comparable between groups. Two patients required plain balloon angioplasty during the RDT procedure to treat renal artery wall oedema. Conclusion: This study was terminated early because of difficulties in recruitment and was underpowered to detect whether RD improved the endpoints of quality of life, exercise function, biomarkers, and left heart remodelling. The procedure was safe in patients with HFpEF, although two patients did require intraprocedure renal artery dilatation
