Panel consumer

After hearing evidence presented to the Food and Drug Administration s Respiratory and Nervous System Device Panel, consumer representative Susan Bartlett Foote (1983) reported back to the FDA that... 

In contrast to all other types of panels, consumers are not given any training, and therefore are only employed for preference and acceptance tests. Their answers are subjective and food acceptance is influenced by many factors like personal experience, sex, age, regular use of the product, eating habits, and social and nutritional aspects. 

The principal U.S. market for methacrylate resins is for glazing and skylights. Other significant markets include consumer products, transportation signs and lighting fixtures, plumbing (spas, tubs, showers, sinks, etc), and panels and siding (106,107). 

New product introductions are generally heavily supported by the technical service function. Many customers using chemical feedstocks to produce multicomponent products for the consumer market require extensive on-line evaluations of new raw materials prior to their acceptance for use. An example of this would be the use of a new engineering polymer for the fabrication of exterior automobile stmctural panels. Full-scale fabrication of the part foUowed by a detailed study of parameters, such as impact strength, colorant behavior, paint receptivity, exterior photodurabiHty, mar resistance, and others, would be required prior to making a raw materials change of this nature. 

Currently, over 110,000 t/yr of engineering resin blends are consumed worldwide, primarily in the transportation, business-machine, hardware, electrical, and appHance industries. Annual growth is projected to be ca 17%/yr. New blends based on PC, terephthalate, and nylon resins are experiencing the greatest expansion (122). These projections could be surpassed if large-volume metal appHcations such as automotive panels are replaced by engineering resin blends which are currently being field-tested. 

Following previous works on physico-chemical characterisation of sunflower low-methoxyl pectins (Alarc o-Silva, 1990, Leitao at al., 1995) and technological utilisation in the manufacture of low calorie gels (Alarc o-Silva et al., 1992), this investigation was carried out to test the suitability of that pectin to the confection of grape juice reduced calorie jellies in comparison with two types of commercial pectin. Aiming at the optimisation of low-calorie jelly formula, based on consumers preferences, the jellies were submitted to a sensory panel test judgement and instrumental texture-analysis. 

Approximately one million metric tons of urea-formaldehyde resin are produced annually all over the world. More than 70% of this urea-formaldehyde resin is consumed by the forest products industry. The resin is used in the production of an adhesive for bonding particleboard (61% of the urea-formaldehyde used in the industry), medium-density fiberboard (27%), hardwood plywood (5%), and as a laminating adhesive (7%) for bonding furniture case goods, overlays to panels, and interior flush doors, for example. 

It is impossible to do very much in the food industry without being involved in taste tests. Taste testing is done in several ways, but two common approaches are either to rely on an expert panel or to use a consumer panel and statistical analysis. 

Expert panels can give rapid answers. Their disadvantages are that they become so expert that they are sensitive to small differences that the consumer would ignore and that they depend on the palate of the experts. If the experts can not detect a taste, which can happen for genetic reasons, then the taste will not be detected. 

Once filed, an NDA undergoes several layers of review (Figure 4.12). A primary review panel generally consists of a chemist, microbiologist, pharmacologist, biostatistician, medical officer and biopharmaceutics scientist. Most hold PhDs in their relevant discipline. The team is organized by a project manager or consumer safety officer (CSO). The CSO initially forwards relevant portions of the NDA to the primary review panel member with the appropriate expertise. 

Manufacture of Printed Wiring Boards. Printed wiring boards, or printed circuit boards, are usually thin flat panels than contain one or multiple layers of thin copper patterns that interconnect the various electronic components (e.g. integrated circuit chips, connectors, resistors) that are attached to the boards. These panels are present in almost every consumer electronic product and automobile sold today. The various photopolymer products used to manufacture the printed wiring boards include film resists, electroless plating resists (23), liquid resists, electrodeposited resists (24), solder masks (25), laser exposed photoresists (26), flexible photoimageable permanent coatings (27) and polyimide interlayer insulator films (28). Another new use of photopolymer chemistry is the selective formation of conductive patterns in polymers (29). 

Monochrome AMPLED flat-panel displays have been made with performance parameters attractive for battery-powered portable applications. The AM backpanel was made of polysilicon material with integrated column and row drivers. Table 1.1 shows a data sheet for a 4" diagonal monochrome display with 960 x 240 pixels [173]. The resolution in horizontal direction was 300 ppi (85pm pitch size), while the resultion in vertical direction was 100 ppi (255 pm pitch size). With 100% pixels turned on at 200 cd/m2, the entire AMPLED panel (including pixel drivers) only consumed eletric power less than 500 mW (with 100% pixels on), which was...
