The design of a mill to treat a certain gold-silver ore by cyanidation

The problem under consideration is the design of a hundred-ton mill for treating silver ores by cyanidation... The Sulphur is partly combined as Sulphide and partly as the Iron Sulphates, FeSO₄ and Fe₂(SO₄)₃. To determine the best method of procedure, preliminary tests were run on lots of 100 pounds each, this being crushed in a sampling grinder and classified into sand a slime --Introduction, page 1

The disease of corruption: views on how to fight corruption to advance 21st century global health goals

Corruption has been described as a disease. When corruption infiltrates global health, it can be particularly devastating, threatening hard gained improvements in human and economic development, international security, and population health. Yet, the multifaceted and complex nature of global health corruption makes it extremely difficult to tackle, despite its enormous costs, which have been estimated in the billions of dollars. In this forum article, we asked anti-corruption experts to identify key priority areas that urgently need global attention in order to advance the fight against global health corruption. The views shared by this multidisciplinary group of contributors reveal several fundamental challenges and allow us to explore potential solutions to address the unique risks posed by health-related corruption. Collectively, these perspectives also provide a roadmap that can be used in support of global health anti-corruption efforts in the post-2015 development agenda

An Analysis of U.S. Student Drug and Alcohol Policies through the Lens of a Professional Ethic for School Leadership

This study explored the moral complexity of student drug and alcohol policies that are often disciplinary, punitive, and exclusionary in nature. The Ethic of the Profession (Shapiro & Stefkovich, 2001, 2005, 2010; Stefkovich, 2006), a professional ethical construct for educational leadership and for school workers writ large, was employed as a theoretical framework to evaluate a bounded case of seven school districts’ pupil policies. This research utilized textual analysis of school policies from the school communities represented in the study in addition to interview data employed in a larger systemic study from which this research is drawn. Findings contribute to a fuller understanding of the valuation process of local administrators when drafting policy in relation to an Ethic of the Profession. Practical implications include the impact of such school policies on the immediate and long-range needs of at-risk students

Radial Velocity Observations and Light Curve Noise Modeling Confirm That Kepler-91b is a Giant Planet Orbiting a Giant Star

Kepler-91b is a rare example of a transiting hot Jupiter around a red giant star, providing the possibility to study the formation and composition of hot Jupiters under different conditions compared to main-sequence stars. However, the planetary nature of Kepler-91b, which was confirmed using phase-curve variations by Lillo-Box et al., was recently called into question based on a re-analysis of Kepler data. We have obtained ground-based radial velocity observations from the Hobby-Eberly Telescope and unambiguously confirm the planetary nature of Kepler-91b by simultaneously modeling the Kepler and radial velocity data. The star exhibits temporally correlated noise due to stellar granulation which we model as a Gaussian Process. We hypothesize that it is this noise component that led previous studies to suspect Kepler-91b to be a false positive. Our work confirms the conclusions presented by Lillo-Box et al. that Kepler-91b is a 0.73+/-0.13 Mjup planet orbiting a red giant star.Comment: Published in Ap

Structural parameters for globular clusters in NGC 5128. III. ACS surface-brightness profiles and model fits

We present internal surface-brightness profiles, based on HST/ACS imaging in the F606W bandpass, for 131 globular cluster (GC) candidates with luminosities 10^4 - 3 x 10^6 solar, in the giant elliptical galaxy NGC 5128. Several structural models are fit to the profile of each cluster and combined with mass-to-light ratios from population-synthesis models, to derive a catalogue of fundamental structural and dynamical parameters parallel in form to the catalogues recently produced by McLaughlin & van der Marel and Barmby et al. for GCs and massive young star clusters in Local Group galaxies. As part of this, we provide corrected and extended parameter estimates for another 18 clusters in NGC 5128, which we observed previously. We show that, like GCs in the Milky Way and some of its satellites, the majority of globulars in NGC 5128 are well fit by isotropic Wilson models, which have intrinsically more distended envelope structures than the standard King lowered isothermal spheres. We use our models to predict internal velocity dispersions for every cluster in our sample. These predictions agree well in general with the observed dispersions in a small number of clusters for which spectroscopic data are available. In a subsequent paper, we use these results to investigate scaling relations for GCs in NGC 5128.Comment: MNRAS, in press. 28 pages.
