Evolution of Physical Oceanography.pdf

October 12, 2009 · Filed Under Oceanography · Comment  · Tags: ,

Taken from Introduction: We have tried to tie the individual chapters together in a variety of ways. The book includes a general index of subjects and names, and also a reference list that gives the page number for each citation in the text. We hope that these features will make possible a rapid’ entry into the book by anyone seeking a discussion of a particular piece of work. Special care was taken in compiling the reference list to correct many common miscitations, some of which extend back nearly 100 years. The reader will notice overlap between chapters and even some dispute among them. We regard this as inevitable and healthy in a field undergoing the ferment of active progress. A consequence of this activity is that we did not attempt to impose a common notation upon the book, but we did ask the authors to avoid idiosyncratic schemes.
In the context of the question to the authors posed above, we are impressed in reading these chapters with how far we have come. When Henry Stommel entered physical oceanography in the early 1940s, the three authors of The Oceans, H. U. Sverdrup, Martin W.
Johnson, and Richard H. Fleming, could cover authoritatively, in one volume, the entirety of oceanography-physics, chemistry, biology, and geology. Today no single volume could cover one of these fields, and probably no three authors would have the temerity to attempt comprehensive descriptions of any. But we believe that the reader will find here a broad description of the present state and the historical evolution of physical oceanography.

Vanquish S V12 - The Ultimate Aston Martin.pdf

August 28, 2009 · Filed Under Aston Martin · Comment  · Tags: ,

Taken from Aston Martin VANQUISH S V12 is the Flagship of the World’s Most Exclusive Sport Car Maker: In 1914, the founders of Aston Martin, Lionel Martin and Robert Bamford, began building handcrafted, highperformance sports cars. They believed sports cars should have a distinctive and individual character, be built to the highest standards and be exhilarating to drive and own. More than 90 years later these values remain true today.
Aston Martin has earned a reputation for another speciality: building lifelong one-to-one relationships with each of its cars and with every owner. This is due to meticulous records and archives, plus personal attention from experts at the factory.
The Vanquish S effortlessly combines 21st Century technology and 200mph (321 km/h) performance, with understated elegance and craftsmanship.
To build such an extraordinary car, the company has used British expertise in aerospace and race-car engineering. Conventional automotive industry materials and manufacturing techniques were not good enough for the fastest road car in Aston Martin’s history

Bridge Detailing Manual.pdf

Taken from definitions:
bridge - A bridge is a single span structure of over 20 feet, measured from face to face of
abutments, or multiple span structures of over 20 feet (including multiple box culverts,
measured between inside of end walls along the centerline of structure). Batteries of pipe
culverts, regardless of their length, are not bridges.
culverts - Culverts are those drainage structures not defined as bridges
highway underpass - A highway underpass is a grade separation where the subject (funding) highway passes under an intersecting highway (also called a Highway Undercrossing)
highway overpass - A highway overpass is a grade separation where the subject (funding) highway passes over an intersecting highway (also called a Highway Overcrossing)
railroad underpass - A railroad underpass is a grade separation where a highway passes
under an intersecting railroad (also called a Railroad Undercrossing)
railroad overpass - A railroad overpass is a grade separation where a highway passes over an intersecting railroad (also called a Railroad Overcrossing)
pedestrian underpass - A pedestrian underpass is a grade separation where a highway passes under an intersecting pedestrian walkway
stream crossing - A stream crossing is a location where the subject highway passes over an
intersecting waterway

Bridge Design Manual - LRFD.pdf

Taken from Implementation: Load and Resistance Factor Design (LRFD) is a design methodology that makes use of load and resistance factors based on the known variability of applied loads and material properties. In 1994, the American Association of State Highway and Transportation Officials (AASHTO) published the first AASHTO Load and Resistance Factor Bridge Design Specifications. The Federal Highway Administration (FHWA) has mandated the use of LRFD for all bridges for which the Texas Department of Transportation (TxDOT) initiates preliminary engineering after October 2007.
