Ground-water resources data of Charlotte, DeSoto, and Hardee Counties, Florida

Charlotte, De Soto, and Hardee counties are east-southeast of Tampa in west-central peninsular Florida, figure 1. In order to plan the future water-resource development of the area, information about the water resources is needed. To meet this need, the Water Resources Division of the U.S. Geological Survey, in cooperation with the Peace River Basin Board of the Southwest Florida Water Management District as part of the statewide cooperative program with the Division of Geology, Florida Board of Conservation, began a continuing hydrologic data collection program in July, 1963, as an initial step in the investigation and evaluation of the groundwater resources of Hardee and De Soto counties. A similar hydrologic data program commenced in Charlotte County in July, 1964. Previous work in Hardee and De Soto counties included a one year reconnaissance by the Division of Water Resources and Conservation, Florida Board of Conservation, which concluded in June, 1963, and resulted in a hydrologic report (Woodard, 1964). As an outgrowth of the hydrologic data program, a Map Series report portraying the chemical character of water in the Floridan aquifer in the southern Peace River basin was prepared in 1967 (Kaufman and Dion). The data contained herein constitute the basis for the Map Series report. Additional selected data, including records of wells and chemical analyses,, on the ground-water resources of the three county area are also included and are published to make the data available.

Recurrent microblazar activity in Cygnus X-1?

Recurrent flaring events at X- and soft gamma-ray energies have been recently reported for the galactic black hole candidate Cygnus X-1. The observed fluxes during these transient outbursts are far higher than what is observed in ``normal'' episodes. Here we suggest that the origin of this radiation is non-thermal and produced by inverse Compton interactions between relativistic electrons in the jet and external photon fields, with a dominant contribution from the companion star field. The recurrent and relatively rapid variability could be explained by the precession of the jet, which results in a variable Doppler amplification.Comment: 4 pages, 5 figures, Accepted for publication in Astronomy & Astrophysics Letter

Self-consistent analytic solution for the current and the access resistance in open ion channels.

A self-consistent analytic approach is introduced for the estimation of the access resistance and the current through an open ion channel for an arbitrary number of species. For an ion current flowing radially inward from infinity to the channel mouth, the Poisson-Boltzmann-Nernst-Planck equations are solved analytically in the bulk with spherical symmetry in three dimensions, by linearization. Within the channel, the Poisson-Nernst-Planck equation is solved analytically in a one-dimensional approximation. An iterative procedure is used to match the two solutions together at the channel mouth in a self-consistent way. It is shown that the currentvoltage characteristics obtained are in good quantitative agreement with experimental measurements

Trade and Aid

Originally published in 1982. Trade and Aid outlines the transition of U.S. foreign policy during the Eisenhower administration. In the years leading up to Eisenhower's election, America's predominant foreign economic program was based on the concept of "trade not aid," which deemphasized foreign aid and relied instead on liberalized world trade and the encouragement of private foreign investment to assure world economic growth. When Eisenhower took office in 1953, he embraced this doctrine. However, as problems in the Third World worsened, it became clear to Eisenhower and other architects of American foreign policy that trade and private investment were insufficient solutions to the economic woes of developing nations. In 1954 Eisenhower began to embrace economic aid as a core axis of his foreign economic policy. Burton I. Kaufman contextualizes Eisenhower's foreign policy leadership in the ongoing historical evaluation of Eisenhower's leadership prowess. He evaluates the outcomes of the Eisenhower administration's trade and aid program, arguing that developing countries were worse off by the time Eisenhower left office

[Introduction to] On Agamben, Arendt, Christianity, and the Dark Arts of Civilization

Many progressives have found passages in Augustine\u27s work that suggest he entertained hopes for meaningful political melioration in his time. They also propose that his “political theology” could be an especially valuable resource for “an ethics of democratic citizenship” or for “hopeful citizenship” in our times. Peter Kaufman argues that Augustine\u27s “political theology” offers a compelling, radical alternative to progressive politics. He chronicles Augustine\u27s experiments with alternative polities, and pairs Augustine\u27s criticisms of political culture with those of Giorgio Agamben and Hannah Arendt.This book argues that the perspectives of pilgrims (Augustine), refugees (Agamben), and pariahs (Arendt) are better staging areas than the perspectives and virtues associated with citizenship-and better for activists interested in genuine political innovation rather than renovation. Kaufman revises the political legacy of Augustine, aiming to influence interdisciplinary conversations among scholars of late antiquity and twenty-first century political theorists, ethicists, and practitioners.https://scholarship.richmond.edu/bookshelf/1367/thumbnail.jp

Size Matters: Gastric Pouch Size as a Predictor of Weight Loss Following Laparoscopic Roux-Y Gastric Bypass

Introduction: The identification of relevant components of successful weight reduction surgery is the most important endeavor in the latest research aiming to increase excess weight loss. Over the past twenty years there has been ongoing discussion about the importance of gastric pouch size as one of the key factors influencing weight loss after restrictive weight reduction surgery. The goal of our analysis is to determine the relationship between pouch size and weight reduction following laparoscopic Roux-Y gastric bypass (LRYGB). Methods: Between August 2002 and March 2005, 321 LRYGB procedures were performed at the same institution. Patient demographics were entered into a longitudinal, prospective database. Upper gastrointestinal series were performed in all patients on postoperative day one. Assuming that pouch depth remained constant, pouch size was calculated as area (cm²) utilizing digital imaging technology and internal standardization for measurement. Linear regression analysis was performed to determine the association between pouch size and weight loss at 6 and 12 months postoperatively. Adjustment was made for age, gender, and preoperative BMI. Results: Mean age was 41 years (range, 17-64); 262 patients were female (81.6%); mean preoperative BM I was 51.1 kg/m² (range, 36.1-89.9 kg/m²). Mean 6 month %EWL was 50.5 (range, 13.4-85.5%) and mean 12 month %EWL was 62.5 (range, 14.6-98.1). Mean pouch size was 63.9 cm2 (range, 8.6-248.0 cm² ). A statistically significant inverse correlation between pouch size and %EWL was found at 6 months (β = -0.241, p\u3c0.01) and at 12 months (β = -0.302, p\u3c0.02). A significant correlation was found between pouch size, male gender and preoperative BMI but not between pouch size and age. Conclusion: Our analysis demonstrates that gastric pouch size is one important component for successful weight reduction following LRYGB. The creation of a small gastric pouch should be encouraged as an initial step towards ideal weight loss

The Production of HI in Photodissociation Regions and A Comparison with CO(1-0) Emission

The gas at the surfaces of molecular clouds in galaxies is heated and dissociated by photons from young stars both near and far. HI resulting from the dissociation of molecular hydrogen H2 emits hyperfine line emission at 21 cm, and warmed CO emits dipole rotational lines such as the 2.6 mm line of CO(1-0). We use previously developed models for photodissociation regions (PDRs) to compute the intensities of these HI and CO(1-0) lines as a function of the total volume density n in the cloud and the far ultraviolet flux G0 incident upon it and present the results in units familiar to observers. The intensities of these two lines behave differently with changing physical conditions in the PDR, and, taken together, the two lines can provide a ground-based radio astronomy diagnostic for determining n and G0 separately in distant molecular clouds. This diagnostic is particularly useful in the range Gzero <~ 100, 10 cm^{-3} <~ n <~ 10^5 cm^{-3}, which applies to a large fraction of the volume of the interstellar medium in galaxies. If the molecular cloud is located near discrete sources of far-UV (FUV) emission, the PDR-generated HI and CO(1-0) emission on the cloud surface can be more easily identified, appearing as layered ``blankets'' or ``blisters'' on the side of the cloud nearest to the FUV source. As an illustration, we consider the Galactic object G216 -2.5, i.e. ``Maddalena's Cloud'', which has been previously identified as a large PDR in the Galaxy. We determine that this cloud has n ~ 200 cm^{-3}, G0 ~ 0.8, consistent with other data.Comment: 13 Pages, 3 Figures. Accepted for publication in the Astrophysical Journa
