Fly ash is a fine, glass-like powder recovered from gases created by coal-fired electric power generation. U.S. power plants produce millions of tons of fly ash annually, which is usually dumped in landfills. Fly ash is an inexpensive replacement for portland cement used in concrete, while it actually improves strength, segregation, and ease of pumping of the concrete. Fly ash is also used as an ingredient in brick, block, paving, and structural fills.
When MIG welding aluminum, obtaining good quality and productivity depends on using the right welding process and system. Because aluminum quickly transfers heat away from the weld area, establishing the weld puddle takes more energy than does steel. However, because aluminum has a relatively low melting point, thin sections of aluminum (which have less mass to transfer heat) are especially prone to burn-through and warping. In short, there’s a fine line between providing sufficient energy to ensure good fusion, yet controlling the heat input to prevent problems.
Crude oil is the world’s most actively traded commodity, and the NYMEX Division light, sweet crude oil futures contract is the world’s most liquid forum for crude oil trading, as well as the world’s largest-volume futures contract trading on a physical commodity. Because of its excellent liquidity and price transparency, the contract is used as a principal international pricing benchmark. Additional risk management and trading opportunities are offered through options on the futures contract; calendar spread options; crack spread options on the pricing differential of heating oil futures and crude oil futures and gasoline futures and crude oil futures; and average price options.
Light sweet crude oil is an especially sought-after form of crude oil which can be used to make products like gasoline, kerosene, and high-quality diesel. Although many consumers think that most crude oil is essentially the same, in fact there are a number of classifications for crude oil which are used to divide the oil by impurities and consistency. Some forms of crude oil are considered more valuable than others, with light sweet crude typically commanding the highest prices on the market.
Below you will find rough definitions for a number of words commonly used in discussions of Japanese ceramics. I suggest using English equivalents whenever possible. If neccessary, give the Japanese term in italics with an English definition in parentheses.
"Return on Investment" (ROI) is often invoked to compare the perceived benefit to the expense of achieving it, usually considered to be cash. We may even be able to come up with a tangible dollar value of the benefit, but then what to do with it?
This is an exciting time for the architecture, engineering, and construction industry. Projects are being designed faster and more accurately than ever before. Much of this success is because of technological improvements we’ve seen during the past decade. General understanding of technologies and new process, as well as adoption of these, occur on varying schedules, depending on the culture of a firm or organization and the personalities of its leaders. However, recent survey results indicate that the A/E/C industry is moving quickly toward an integrated, digital environment soundly based on 3-D information.
Building Information Modeling (BIM) is the process of creating an intelligent and computable 3-D data set, and coordinating and sharing the project information with various types of professionals during design, construction, and operations. The goal of this process is to improve collaboration among project participants. BIM is not defined by simply creating a 3-D data set for internal analysis. Although it has been a trend receiving much attention in the architecture and facilities management fields, as well as mechanical, electrical, plumbing, and structural engineering, civil engineering is also becoming involved.
In a continuing effort toadvance the use of environmentally responsible techniques and technologies in residential construction, the NAHB, the International Code Council (ICC), and the NAHB Research Center are close to attaining final approval for an American National Standards Institute (ANSI) standard for green home building construction practices. After completion of the ANSI process, the National Green Building Standard will be promulgated as a joint publication between the NAHB and ICC.
