Winner of the 2021 Cave Canem Poetry Prize, selected by Rachel Eliza Griffiths In her virtuosic debut, Courtney Faye Taylor explores the under-told history of the murder of Latasha Harlins—a fifteen-year-old Black girl killed by a Korean shop owner, Soon Ja Du, after being falsely accused of shoplifting a bottle of orange juice. Harlins’s murder and the following trial, which resulted in no prison time for Du, were inciting incidents of the 1992 Los Angeles uprising, and came to exemplify the long-fraught relationship between Black and Asian American communities in the United States. Through a collage-like approach to collective history and storytelling, Taylor’s poems present a profound look into the insidious points at which violence originates against—and between—women of color. Concentrate displays an astounding breadth of form and experimentation in found texts, micro-essays, and visual poems, merging worlds and bending time in order to interrogate inexorable encounters with American patriarchy and White supremacy manifested as sexual and racially charged violence. These poems demand absolute focus on Black womanhood’s relentless refusal to be unseen, even and especially when such luminosity exposes an exceptional vulnerability to harm and erasure. Taylor’s inventive, intimate book radically reconsiders the cost of memory, forging a path to a future rooted in solidarity and possibility. “Concentrate,” she writes. “We have decisions to make. Fire is that decision to make.”

This book is about success and transformation. It shows how, with patience and energy, parents and teachers can turn a child who is noisy, clumsy and forgetful into a child who is calm, careful and attentive. Creating Kids Who Can Concentrate is a practical and realistic book that shows how parents and professionals can naturally and effectively develop a child's potential to become responsible and thoughtful in a remarkably short time. The authors provide expert guidance on: * proven techiques and strategies for overcoming barriers to learning * developing every child's innate skills * how a child is labelled as having A.D.D. * dealing with disruptive or bizarre behaviour, tantrums and children who won't listen JEAN ROBB and HILARY LETTS are teachers and therapists as well as the founders of Successful Learning, a British education centre dedicated to helping children to fulfil their potential. Their first book is CREATING KIDS WHO CAN.

Prepared by the Task Committee on the Development of Prestandards for Concentrate Management Case Studies of the Desalination and Water Reuse Technical Committee of the Water, Wastewater, and Stormwater Council of the Environmental and Water Resources Institute of ASCE.Concentrate Management in Desalination: Case Studies, Second Edition, reviews the state-of-the-practice for managing concentrate streams resulting from desalination processes.Concentrate management and disposal in desalination pose environmental and cost concerns--and often determine whether a desalination project is viable, especially for inland communities. This book examines many facets of concentrate management in desalination, including process design and configuration; regulatory setting; environmental, climate change, and sustainability issues; and economic evaluation of projects. Thirteen case studies are offered to demonstrate different techniques for disposing of concentrates associated with the following types of projects: ocean and bays discharge, sanitary sewer or surface water disposal, deep-well injection, zero liquid discharge (ZLD) or near ZLD, and land disposal and/or evaporation ponds.Environmental engineers, water practitioners and managers responsible for the design, operation, research, and evaluation of regional desalination and water reuse facilities will find a wealth of practical information in this updated and expanded edition.

The Bureau of Mines devised a procedure for selectively extracting platinum-group metals (PGM) and gold from Stillwater Complex flotation concentrate. The Stillwater Complex is the only major U.S. PGM resource. Development of a suitable extraction technique will contribute to its exploitation. The concentrate was roasted at 1,050° C to convert host base-metal sulfides to oxides and the PGM from sulfide minerals to their elemental states. The roasted concentrate was preleached with dilute sulfuric acid to remove easily soluble gangue minerals. After pre-leaching, the concentrate was slurried with 6M HCI and leached at ambient temperature and pressure with a strong-oxidizing agent. Hydrogen peroxide, chlorine, sodium hypochlorite, nitric acid, and a persulfate salt were the oxidants investigated. The two-stage leaching scheme ex-tracted up to 97 pct of the platinum, 92 pct of the palladium, and 99 pct of the gold from the roasted concentrate. The base metals were not solubilized and reported to the residue. No attempt was made to devise a procedure to recover the copper and nickel because they comprise less than 5 pct of the value of the concentrate. Viable techniques for recovering the precious metals from the pregnant solution were sulfide precipitation, cementation with nickel, or adsorption on activated carbon.

A ferrous chloride-oxygen leaching system was investigated by the Federal Bureau of Mines to determine its effectiveness for recovering copper and silver from a tetrahedrite concentrate that had been pretreated to remove a majority of the antimony. The pretreated concentrate contained copper, silver, lead, zinc, antimony, and arsenic. Parameters affecting metal extraction (such as temperature, pressure, amount of ferrous chloride, and initial hydrogen ion concentration) were studied. Copper extraction of 98 pct was achieved by leaching 4 hours at 40 pounds per square inch gage (psig) and 100° C. Copper was recovered from leach solutions by cementation with iron, and the resulting ferrous chloride was recycled. Leaching the residue with cyanide following electrowinning recovered 99.7 pct of the silver. Iron, antimony, arsenic, and sulfur reported to the tailings.
