We shall describe the advances that took place during the 150 years after Newton when the laws of motion were reformulated using more powerful techniques and ideas developed by some of the giants of mathematical physics: people such as Euler, Lagrange, Hamilton and Jacobi.

In this work, we review a number of methods for finding a finite algebra with a given congruence lattice, including searching for intervals in subgroup lattices. We also consider methods for proving that algebras with a given congruence lattice exist without actually constructing them. By combining these well known methods with a new method we have developed, we prove that with one possible exception every lattice with at most seven elements is isomorphic to the congruence lattice of a finite algebra.

EB 217 White Cement Concrete
Author: James A. Farny | Size: 1 MB | Format:PDF | Quality:Original preprint | Publisher: Portland Cement Association | Year: 2001 | pages: 30
White cement is a key ingredient in architectural and decorative concrete. Regularly chosen for its appearance, white cement concrete has many applications and provides benefits such as safety, energy efficiency, and low maintenance. This publication provides architects, ready mix producers, and contractors with the information necessary to design, mix, and place attractive white cement and colored concrete. Technical information presented in this text is applicable to cast-in-place, precast, and tilt-up construction.
White and colored concrete are materials of choice for use in architectural concrete. This handbook is intended to improve white and colored concrete construction by providing technical information to designers (architects, engineers, specifiers), contractors, and ready-mix producers.
Though decorative concrete is more expensive than plain concrete, it is also more affordable than natural materials like limestone, cut stone, field stone, cobblestone, marble, or granite. Concrete can emulate these and many other materials to create durable structures with an attractive appearance. Included full-color photos illustrate applications and techniques.

EB 220 Life Cycle Cost Analysis A Guide for Comparing Alternate Pavement Designs
Author: Steven M Waalkes | Size: 1 MB | Format:PDF | Quality:Original preprint | Publisher: Portland Cement Association | pages: 56
Life cycle cost analysis (LCCA) is an economic procedure used to compare competing design alternates, over the lives of each alternate, considering all significant costs and benefits, expressed in equivalent dollars.
It is important to understand that LCCA is an economic tool that determines which alternate has the best value and not an engineering tool that determines how long an alternate will last or how well it will perform. This does not mean that engineering is not an important element of the life cycle cost analysis. Proper engineering must be used to ensure that each rival alternate meets the design criteria and provides similar results. If the alternates do not provide similar performance, then an economic assessment using LCCA to compare them is not realistic or reliable.

SP 041 Concrete Floor Systems Guide to Estimating and Economizing
Author: August W Domel, SK. Ghosh | Size: 1 MB | Format:PDF | Quality:Scanner | Publisher: Portland Cement Association | Year: 1990 | pages: 36
Preliminary estimates of material quantities (concrete, reinforcing steel, and formwork) for various span and loading conditions help with planning. The effects of different concrete strengths, column dimensions, and floor aspect ratios on material quantities are discussed to facilitate decision making. Charts containing relative cost indices help in making comparisons and selecting the most economical floor system.
