This is not your run-of-the-mill fitness book. Developed by world-renowned gluteal expert Bret Contreras, Strong Curves offers an extensive fitness and nutrition guide for women seeking to improve their physique, function, strength, and mobility. Contreras spent the last eighteen years researching and field-testing the best methods for building better butts and shapelier bodies. In Strong Curves, he offers the programs that have proven effective time and time again with his clients, allowing you to develop lean muscle, rounded glutes, and greater confidence. Each page is packed with information decoding the female anatomy, providing a better understanding as to why most fitness programs fail to help women reach their goals. With a comprehensive nutritional guide and over 200 strength exercises, this book gets women off the treadmill and furnishes their drive to achieve strength, power, and sexy curves from head to toe. Although the glutes are the largest and most powerful muscle group in the human body, they often go dormant due to lifestyle choices, leading to a flat, saggy bum. Strong Curves is the cure.

The best-selling guide for coping with changes in life and work, named one of the 50 all-time best books in self-help and personal development Whether you choose it or it is thrust upon you, change brings both opportunities and turmoil.

With the understanding born of both personal and professional experience, William Bridges takes readers step by step through the three stages of any transition: The Ending, The Neutral Zone, and, eventually, The New Beginning. Bridges explains how each stage can be understood and embraced, leading to meaningful and productive movement into a hopeful future. With a new introduction highlighting how the advice in the book continues to apply and is perhaps even more relevant today, and a new chapter devoted to change in the workplace, Transitions will remain the essential guide for coping with the one constant in life: change.

An anonymous valentine changes the life of the unsociable Mr. Hatch, turning him into a laughing friend who helps and appreciates all his neighbors.

Marvin Denmark, a builder and craftsman with 45+ years of experience, demonstrates the process he used to design and construct a small cable suspension bridge. This book includes some suspension bridge history along with engineering considerations, then explains and illustrates with diagrams and full-color photos the step by step process that was used to complete the project. His blog, wildcatman.wordpress.com, has excerpts from the book, a new cable locking system design, and a recent price list for parts for his bridge. A trailer for the cable locking system including video of the bridge building process is here:http://www.youtube.com/watch?v=cLXrzC9K5wQ Anyone who is looking for ideas for a footbridge that is relatively easy to build without the use of heavy equipment or difficult to replace components may benefit from the design in this book and by using the patented "cable locking system."

Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.
