Chimneys and Towers by Betsy Fahlman,Claire Barry,Charles Demuth Pdf
Chimneys and Towers focuses on Demuth's late paintings of industrial sites in Lancaster. Depicting the warehouses and factories of the city's tobacco and linoleum industries in sharp, geometric forms, these paintings bring to the depiction of his hometown the style of the American avant-garde that he helped create.
Chimney Swifts, birds that nest and roost in chimneys, have been historically abundant in North America. But by the late 1980s, the number of swifts migrating to North America from the Amazon River Basin had declined. A growing number of people across North America are now constructing nesting towers and conducting Chimney Swift conservation projects in their own communities. With Chimney Swift Towers, concerned bird conservationists have a step-by-step guide to help them create more habitat for these beneficial, insect-eating birds. Chimney Swift experts Paul and Georgean Kyle give directions for building freestanding wooden towers, wooden kiosk towers, masonry towers, and other structures. Included are - design basics, - lists of materials needed, - useful diagrams and photographs, - and detailed instructions on site preparation, tower construction, installation, and maintenance. Anyone with basic woodworking or masonry skills and an interest in wildlife conservation will find this publication helpful. That includes do-it-yourselfers, homeowners involved in creating backyard habitat for wildlife, landscape and structural architects, park and wildscape managers, wildlife management area professionals, nature centers, garden centers, scout troops, and other civic organizations in search of community service projects.

Wind Effects on Structures by Emil Simiu,DongHun Yeo Pdf
Provides structural engineers with the knowledge and practical tools needed to perform structural designs for wind that incorporate major technological, conceptual, analytical and computational advances achieved in the last two decades. With clear explanations and documentation of the concepts, methods, algorithms, and software available for accounting for wind loads in structural design, it also describes the wind engineer's contributions in sufficient detail that they can be effectively scrutinized by the structural engineer in charge of the design. Wind Effects on Structures: Modern Structural Design for Wind, 4th Edition is organized in four sections. The first covers atmospheric flows, extreme wind speeds, and bluff body aerodynamics. The second examines the design of buildings, and includes chapters on aerodynamic loads; dynamic and effective wind-induced loads; wind effects with specified MRIs; low-rise buildings; tall buildings; and more. The third part is devoted to aeroelastic effects, and covers both fundamentals and applications. The last part considers other structures and special topics such as trussed frameworks; offshore structures; and tornado effects. Offering readers the knowledge and practical tools needed to develop structural designs for wind loadings, this book: Points out significant limitations in the design of buildings based on such techniques as the high-frequency force balance Discusses powerful algorithms, tools, and software needed for the effective design for wind, and provides numerous examples of application Discusses techniques applicable to structures other than buildings, including stacks and suspended-span bridges Features several appendices on Elements of Probability and Statistics; Peaks-over-Threshold Poisson-Process Procedure for Estimating Peaks; estimates of the WTC Towers’ Response to Wind and their shortcomings; and more Wind Effects on Structures: Modern Structural Design for Wind, 4th Edition is an excellent text for structural engineers, wind engineers, and structural engineering students and faculty.
Chimney Swifts by Paul D. Kyle,Georgean Z. Kyle Pdf
The Kyles share their knowledge and provide a peek into the secret life of these beneficial, insect-eating birds, and practical guidelines for homeowners to coexist peacefully with these remarkable birds.
The Birdhouse Book by Margaret A. Barker,Elissa Ruth Wolfson,National Audubon Society Pdf
The Audubon Birdhouse Book is the most authoritative book available for creating safe, sturdy, and easy-to-build homes for many of North America’s favorite birds. This updated second edition includes important new and timely topics including impacts of climate change on birds, nestbox monitoring for community science, native plants, and how birders can help birds. Produced in association with the National Audubon Society, Audubon Birdhouse Book explains how to build and place functional DIY bird homes that are safe and appropriate for more than 20 classic North American species, from wrens to raptors. Each of the easy-to-build boxes and shelves within is accompanied by cut lists, specially created line diagrams, and step-by-step photography, making the projects accessible to those with even the most rudimentary woodworking skills. In addition, this practical and beautifully presented guide is packed with color photography and information about the bird species covered: Wrens, Warblers, Bluebirds, Flycatchers, Swallows, Titmice, Owls, Flickers, Kestrels, Chickadees, Ducks, Mergansers, Swallows, Doves, Swallows, Robins, Finches, Phoebes, Loons, Swifts, Herons, and Ospreys. Detailed information will help you properly place and maintain the homes to attract birds. And because these projects are the product of years of experience and field-testing, you can be sure you’re getting the best advice regarding proper design, safe construction materials, and correct home placement to mitigate exposure to elements, pests, and predators. Finally, beyond the birdhouses, you’ll find out how you can contribute to the larger birding community and even enhance your birding experience.

Reservoir Safety and the Environment by British Dam Society. Conference Pdf
Addresses the concerns of the dam engineering community, and summarizes experiences in safety analysis and the works on both embankment and concrete dams. This book provides an analysis on the subjects in the field of reservoir engineering, and is designed for those involved in reservoir design and construction, both in the UK and overseas.
Analysis of a Rotatable Wind Turbine Tower by means of Aero-Servo-Elastic Load Simulations by Struve, Achim Pdf
This work highlights how the costs and CO2-emissions of land-based wind turbines can be reduced by means of an innovative and material efficient support structure concept. Thereby the yaw system is placed at the tower base, allowing the whole wind turbine tower to be rotated. The potential of a rotatable inclined lattice tower concept was analysed by means of aero-servo-elastic load simulations in the FAST environment. A balance between different cost aspects revealed significant savings.
