The Public Health and Economic Impacts of Persistent, Bioaccumulative, and Toxic (PBT) Contaminants on U.S. Fisheries

Widely dispersed information from the public health, economic, and fisheries management literature is synthesized to examine the impacts of PBT contamination, including current and potential impacts on public health and the ongoing economic impacts this contamination has on the U.S. fishing industry.Environmental Economics and Policy,

Exacting Public Beach Access: The Viability of Permit Conditions and Florida\u27s State Beach Access Laws After Dolan v. City of Tigard

In the aftermath of Nollan v. California Coastal Commission and Dolan v. City of Tigard, local governments may find it more difficult to utilize permit conditions as a tool for preserving beach access. This Comment explores the viability of Florida\u27s beach access laws after these decisions, examining the potential effects on permitting for construction at the local level. As an introduction, the Comment reviews Florida\u27s current beach access statutes and discusses the Nollan and Dolan cases. The Comment then analyzes the true meaning of the rough proportionality requirement of Dolan, entertaining views from subsequent case law and commentators. Additionally, the Comment addresses problems that Dolan may create in Florida\u27s access laws. The Comment concludes by offering suggestions to preserve beach access in Florida, including proposals for amending Florida\u27s statutory chapter on beach access, platting of public beach access points, and creating a citizen standing provision to enforce beach access

Scaling graphs of heart rate time series in athletes demonstrate the VLF, LF and HF regions

Scaling analysis of heart rate time series has emerged as an useful tool for assessment of autonomic cardiac control. We investigate the heart rate time series of ten athletes (five males and five females), by applying detrended fluctuation analysis (DFA). High resolution ECGs are recorded under standardized resting conditions over 30 minutes and subsequently heart rate time series are extracted and artefacts filtered. We find three distinct regions of scale-invariance, which correspond to the well-known VLF, LF, and HF bands in the power spectra of heart rate variability. The scaling exponents alpha are alphaHF: 1.15 [0.96-1.22], alphaLF: 0.68 [0.57-0.84], alphaVLF: 0.83[0.82-0.99]; p<10^-5). In conclusion, DFA scaling exponents of heart rate time series should be fitted to the VLF, LF, and HF ranges, respectively

Polymer Dissolution Model: An Energy Adaptation Of The Critical Ionization Theory

The current scale of features size in the microelectronics industry has reached the point where molecular level interactions affect process fidelity and produce excursions from the continuum world like line edge roughness (LER). Here we present a 3D molecular level model based on the adaptation of the critical ionization (CI) theory using a fundamental interaction energy approach. The model asserts that it is the favorable interaction between the ionized part of the polymer and the developer solution which renders the polymer soluble. Dynamic Monte Carlo methods were used in the current model to study the polymer dissolution phenomenon. The surface ionization was captured by employing an electric double layer at the interface, and polymer motion was simulated using the Metropolis algorithm. The approximated interaction parameters, for different species in the system, were obtained experimentally and used to calibrate the simulated dissolution rate response to polymer molecular weight and developer concentration. The predicted response is in good agreement with experimental dissolution rate data. The simulation results support the premise of the CI theory and provide an insight into the CI model from a new prospective. This model may provide a means to study the contribution of development to LER and other related defects based on molecular level interactions between distinct components in the polymer and the developer.Chemical Engineerin
