Wood composites today represent a matrix of opportunity. Each product seeks its own distinctive competitive advantage. A few of the commercially available products include  

Data from several plywood machinery suppliers (Spelter and Sleet, 1989). The 1990 estimate is supplied by Sleet pers. comm.). With approximately 200 lathes in the United States and with major lathe changes too e q)ensive for the smaller mills adaptation of 140 or so corresponds to effective market saturation. 

US dollar costs per for 9.5 mm (3/8 in) panels. The higher energy charges for OSB in the late 1980 s is due to less wood waste and the need to buy more power. Assumptions include plywood bolts decreasing from 355 to 230 mm, with target core sizes of 135 and 50 mm respectively and that OSB resin switching from 5.6% liquid to 2.1% powdered PF resin. 

Narrow veneers are jointed to make up full sheets that ean be laminated onto any panel to provide a decorative finish the panel requires a balaneing veneer on its reverse face but this need not be of similar quality if it is not seen. Where alternate strips are turned over to become mirror images of one another the pattern is called book-matched. In this situation every second strip will have its loose face in view, and smooth tight veneer is essential if a high quality decorative finish is sought.

The type of hardware or computer system to be used and the potential size of the database should also be considered. Eor some databases, a personal computer may be adequate. Eor others, especiaUy if there wiU be multiple users, a mainframe computer or a network of personal computers may be required. Storage capacity and response time are parameters that should be considered. However, computer technology changes so rapidly that vendors and computer experts should be consulted when building any personal databases. 

Eig. 1. The pace of technological change ia both the microelectronics-based computer revolution, as characterized by the number of bits in a DRAM, and the industrial revolution, as characterized by the horsepower developed by a steam engine (19). 

During process development, a model can be developed as soon as a conceptual flow sheet has been formulated. This model can be updated as more information about the process is obtained. Even at an early stage in the project, the model can be used to assess the preliminary economics of the process and the effect of technological changes on these economics. The model can aid in interpreting pilot-plant data and allows the study of many process alternatives. 

The principal technological changes in the engineering control of air pollution were the perfection of the motor-driven fan, which allowed large-scale gas-treating systems to be built the invention of the electrostatic precipitator, which made particulate control in many processes feasible and the development of a chemical engineering capability for the design of process equipment, which made the control of gas and vapor effluents feasible.

People develop bad habits and take things for granted processes, equipment, and technology change, so retraining is essential at appropriate intervals. 

In sum, for appliances, energy efficiency technology improvements are not always adopted even after they become well understood and technology changes do not necessarily lead to improved energy efficiency. 

Accordingly, technological change m refining technology has centered on alterations and improve-... 

In today s world the decision is more complex. Markets are more sophisticated, skills can be in short supply, technological change can soon outdate newly installed processes, and there has been a phenomenal revolution in communications, both in terms of the physical movement of goods and people and of information around the world. As a consequence, companies often have to consider a wide number of options, and the eventual decision is based on optimizing the perceived net benefits. 

Technological changes or changes in production volume reflecting the popularity of an alloy or protective treatment as confidence is gained in its use may reduce, or even reverse, the effect of inflation on some costs. In combination with inflation, these factors can greatly alter the economic order of merit of possible solutions over even a short period. Consequently, decisions should always be based on up-to-date information, and past comparisons of alternatives regarded with some suspicion.

Every time technology transitions, a different set of capabilities and limitations is offered. Eor instance, software may be available on one platform but not another. Each technology change requires careful planning and project management to ensure that there is no disruption to the organization and no loss of data. 

This chapter briefly discusses the future of SAS programming and the SAS programmer in the world of clinical trials. The impact of the business environment, regulatory issues, technological changes, and standards organizations on the future of SAS programming in clinical trials is addressed.

In this process EAF dust, other zinc-bearing wastes, recycled materials, coke or coal, lime, and silica are mixed and fed to a rotary furnace. The zinc and other volatile nonferrous metals in the feed are entrained in the furnace off-gas and are carried from the furnace to an external dust collection system. The resulting oxide (zinc calcine) is a crude zinc-bearing product that is further refined at zinc smelters. A byproduct of the process is a nonhazardous, iron-rich slag that can be used in road construction. Solidification technologies change the physical form of the waste to produce a solid structure in which the contaminant is mechanically trapped. 

The hazardous waste identification process is subject to critical review, and adjusted accordingly to reflect technology changes and new information. The hazardous waste listings are particularly dynamic as U.S. EPA conducts further research to incorporate new listings. The following is a brief discussion of several developments to hazardous waste identification.
