Polypropylene. Polypropylene (PP) is used ia packagiag appHcations as films and ia rigid containers. Battery cases could be considered another packagiag appHcation. Dead batteries are often collected at the poiat of sale of new batteries. In the U.S., some states have laws mandating this. Lead, acid, and plastics, particularly PP from battery casiags is recovered and recycled (3). Care must be taken to limit worker exposure to lead duting this process (44). PP is also recovered from bale wrap and other PP fabrics used for wrappiag ia the textile iadustry and from other containers (45).

Nonwoven wipe categories include products for babies and adults, the food service and electronics industries, medical and clean room appHcations, industrial cleaning, computer diskettes, and household products such as dusters, tea towels, shoe cleaning cloths, towelettes, and hand towels. Nonwoven fabrics are used to filter air, water, petroleum (qv), food, and beverages. Nonwovens loaded with abrasives, cleansers, or finishes can be found in a variety of products used by many industries and in many homes to scour or poHsh. Also, a majority of garments designed to protect industrial workers and consumers from hazardous environments are made from nonwoven fabrics.

It is often assumed that TA cannot be applied during design, because until the plant has been fabricated the tasks to be performed by workers cannot be defined in sufficient detail. In fact, many TA techniques can be used to specify the nature of the tasks to achieve the required process plant functions, even before the exact configuration of the system has been finalized. This point will be elaborated later in the context of hierarchical task analysis. 

Since multiple electrical and optical functionality must be combined in the fabrication of an OLED, many workers have turned to the techniques of molecular self-assembly in order to optimize the microstructure of the materials used. In turn, such approaches necessitate the incorporation of additional chemical functionality into the molecules. For example, the successive dipping of a substrate into solutions of polyanion and polycation leads to the deposition of poly-ionic bilayers [59, 60]. Since the precursor form of PPV is cationic, this is a very appealing way to tailor its properties. Anionic polymers that have been studied include sulfonatcd polystyrene [59] and sulfonatcd polyanilinc 159, 60]. Thermal conversion of the precursor PPV then results in an electroluminescent blended polymer film.

Research on semiconductor nanoparticle technology by chemists, materials scientists, and physicists has already led to the fabrication of a number of devices. Initially, Alivisatos and co-workers developed an electroluminescence device from a dispersion of CdSe nanoparticles capped with a conducting polymer349 and then improved on this by replacing the polymer with a layer of CdS, producing a device with efficiency and lifetime increased by factors of 8 and 10, respectively. 0 Chemical synthetic methods for the assembly of nanocrystal composites, consisting of II-VI quantum dot polymer composite materials,351 represent one important step towards the fabrication of new functional devices that incorporate quantum dots. 

In 1932, nine out of ten kilos of textiles the Germans used had been imported. This ratio applied to most other household things. Farben went into the forests. Soon every other citizen arose to the tinkle of a Farben plastic clock, rolled back a new synthetic-fabric spread. Every other man shaved with Farben soap that had been made from the residue of the paraffin that had been made from the coal. At least twice a week, the German ate a new Farben food cooked in synthetic fat. Six out of ten dinner tables were spread with Farben cloths. After the worker went to his job, his wife cleaned the linen, the curtains, the casements, and dusted the furniture goods — all made from beechwood. 

To take radio-activity alone. .. perhaps there is no discovery of modern times which has so disorganized the fertile but by no means plastic brain and imagination of the workers in physical science as this bomb which overthrew with a mighty force all current and reputable theories of the constitution of Matter and its inherent quality. It was the assumption that Matter existed alone in the dense ponderable condition, which we have been told by generations of scientists is its main characteristic, that caused them to fabricate the Mechanical Theory of Nature.
