Discusses the range of benefits resulting from recycling efforts and projects. Presents information and data related to the recycling of metals, cans, paper, fans, and plastics. Suggestions for motivating and involving youth in recycling programs are also offered. (ML)

How a plastics curriculum was changed to satisfy the needs of industry. (Editor)

Describes geothermal, aerospace, and undersea applications of polymeric materials, focusing on properties needed by and forces acting on the polymers. (JN)

Presents a description, course outline, review articles and rationale for a course on Polymerization Reaction Engineering at Purdue University, Indiana. (JN)

The training adviser's role is changing from trainer to problem analyst. Some of the problems being dealt with include: (1) the school to industry transition, (2) new training methods for the 16 to 18 year old entry worker, (3) foreign language training, (4) safety programs, and (5) tire-fitter training. (MW)

A project was conducted at Delaware County Community College, Media, Pennsylvania, to train two instructional staff members in the area of composite materials technology. A 1-year training program was set up for the two technical instructional specialists at the Boeing Helicopter Training Center, Eddystone, Pennsylvania. The program consisted of…

Environmental impacts arise from entanglement of marine animals in plastic debris and from ingestion of plastics by marine organisms. Plastic debris can cause potential threats to humans when divers become entangled or vessels become fouled in debris. The depletion of fishery resources, vessel damage, and aesthetic degradation resulting in lost…

This document, one of eight in a multi-cultural competency-based vocational/technical curricula series, is on fiberglass technician. This program covers 12 instructional areas: orientation, safety, introduction to fiberglass-reinforced plastics, hand lay-up, introduction to equipment operation, chopper operation, gel-coat equipment, finish and…

To establish criteria for developing plastics education programs for industrial education which meet the needs of the plastic industry, 163 (81 percent) questionnaires were completed by processors and converters. Trade journals, magazines, textbooks, and other studies in plastics education provided further information. Conclusions drawn from the…

A unit of study suitable for secondary school chemistry classes. (BB)

Details ab initio crystal orbital calculations using all-trans-polyethylene as a model. Describes calculations based on various forms of translational symmetry. Compares these calculations with ab initio molecular orbital calculations discussed in a preceding article. Discusses three major approximations made in the crystal case. (CW)

In this article, the third part of a series, the results of ab initio polymer calculations presented in part 2 are discussed. The electronic structure of polymers, symmetry properties of band structure, and generalizations are presented. (CW)

This handbook provides information for persons who are preparing to take a test for certification in the plastics industry. The nine sections of the handbook provide information on the following: (1) the mission of the Society of the Plastics Industry and the value of the National Certification in Plastics; (2) tips on preparing for the exam; (3)…

Described is a series of four graduate level courses in polymer science, offered or currently in preparation, at Stanford University. Course descriptions and a list of required and recommended texts are included. Detailed course outlines for two of the courses are presented. (BT)

Classroom demonstrations of selected mechanical properties of polymers are described that can be used to make quantitative measurements. Stiffness, strength, and extensibility are mechanical properties used to distinguish one polymer from another. (KR)
