Literary Nonfiction. Memoir. Wendy C. Ortiz was an only child and a bookish, insecure girl living with alcoholic parents in the San Fernando Valley of Los Angeles in the late 1980s and early 1990s. Her relationship with a charming and deeply flawed private school teacher fifteen years her senior appeared to give her the kind of power teenagers wish for, regardless of consequences. Her teacher—now a registered sex offender—continually encouraged her passion for writing while making her promise she was not leaving any written record about their dangerous sexual relationship. This conflicted relationship with her teacher may have been just five years long, but would imprint itself on her and her later relationships, queer and straight, for the rest of her life. In EXCAVATION: A MEMOIR, the black and white of the standard victim/perpetrator stereotype gives way to unsettling grays. The present- day narrator reflects on the girl she once was, as well as the teacher and parent she has become. It's a beautifully written and powerful story of a woman reclaiming her whole heart.
This manual shows you, in simple, easy -to-understand language, how to calculate the amount of dirt you'll have to move, the cost of owning and operating the machines you'll do it with, and finally, how to assign bid prices to each part of the job. Using clear, detailed illustrations and examples, the author makes it easy to follow and duplicate his system. The book ends with a complete sample estimate, from the take-off to completing the bid sheet.Included in this book: -- How to set up & use an organized & logical estimating system -- How to read plans & specs -- Why a site visit is mandatory -- How to assess accessibility & job difficulty -- How soil haracteristics can affect your estimate -- The best ways to evaluate subsurface conditions -- Figuring your overhead -- How to get the information you need from contour maps -- When you have to undercut -- Dealing with irregular regions and odd areas -- Factors for estimating swell and shrinkage -- Balancing the job: spoil & borrow -- Calculating machine owning & operating costs -- The two common methods of estimating earthwork quantities
Pipeline contracting can be rewarding work -- or a profitable sideline for any excavation contractor. But not everyone who owns a backhoe is ready to start bidding water, sewer and drainage jobs.

A heart-stopping adventure from the NEW YORK TIMES bestselling author of MAP OF BONES and THE DOOMSDAY KEY. High in the Andes, Dr Henry Conklin discovers a 500-year-old mummy that should not be there. While deep in the South American jungle, Conklin's nephew, Sam, stumbles upon a remarkable site nestled between two towering peaks, a place hidden from human eyes for thousands of years. Ingenious traps have been laid to ensnare the careless and unsuspecting, and wealth beyond imagining could be the reward for those with the courage to face the terrible unknown. But where the perilous journey inward ends - in the cold, shrouded heart of a breathtaking necropolis - something else is waiting for Sam Conklin and his exploratory party. A thing created by Man, yet not humanly possible. Something wondrous...something terrifying.
Philip Barker's survey of current excavation techniques - at once authoritative and stimulating - was immeadiately hailed as the standard work and is one of the most widely used archaeological field manuals. Now in its third edition, it has again been revised, updated and expanded to include the latest developments in archaeological techniques.
With continued economic development and increasing urbanization, excavations go deeper and become larger in scale, and are sometimes even carried out in difficult soils. These conditions require advanced analysis and design methods and construction technologies. Most books on general foundation engineering introduce the basic analysis and design of excavation, but do not delve into practical considerations. This book examines both theory and practice, from basic to advanced, and discusses the major methods currently in practice around the world. Each chapter also includes problems and their solutions to develop a practical, real-world understanding.
The relationship between archaeology and conservation has long been complex and, at times, challenging. Archaeologists are often seen as interested principally in excavation and research, while conservators are concerned mainly with stabilization and the prevention of deterioration. Yet it is often initial conservation in the field that determines the long-term survival and intelligibility of both moveable artifacts and fixed architectural features. This user-friendly guide to conservation practices on archaeological excavations covers both structures and artifacts, starting from the moment when they are uncovered. Individual chapters discuss excavation and conservation, environmental and soil issues, deterioration, identification and condition assessment, detachment and removal, initial cleaning, coverings and shelters, packing, and documentation. There are also eight appendixes. Geared primarily for professionals engaged in the physical practice of excavation, this book will also interest archaeologists, archaeological conservators, site managers, conservation scientists, museum curators, and students of archaeology and conservation.
The burial tumulus of Lofkend lies in one of the richest archaeological areas of Albania (ancient "Illyria"), home to a number of burial tumuli spanning the Bronze and Iron Ages of later prehistory. Some were robbed long ago, others were reused for modern burials; few were excavated under scientific conditions. Modern understanding of the pre- and protohistory of Illyria has largely been shaped by the contents of such burial mounds. What inspired the systematic exploration of Lofkend by UCLA was more than the promise of an unplundered necropolis; it was also a chance to revisit the significance of this tumulus and its fellows for the emergence of urbanism and complexity in ancient Illyria. In addition to artifacts, the recovery of surviving plant remains, bones, and other organic material contribute insights into the environmental and ecological history of the region.
Currently there is no reason, in most cases of cavitated caries lesions, to remove affected tissue. This book presents evidence-based research on the topic and provides assessments of diagnostic devices. It offers new insights into how a dentine carious cavity can be managed by either tissue removal or restoration. Methods for preserving dental tissue are presented and ample evidence highlights the need to seal with a quality restorative material. An update on how to conduct a randomized clinical trial is followed by a chapter on agreed upon terminology for supporting improved communication among oral health professionals around the world. This is a must-read for general practitioners, restorative specialists, dental students, and oral hygienists/therapists.
