Mezcla íntima de salitre, sulfuro y carbón utilizada como detonador, cebo y propulsor de explosivo.

Polyacrylamide gel electrophoresis (PAGE) subjects proteins coated in an anionic detergent to electrophoresis in a polyacrylamide gel in order to determine their molecular weight.

Colorless liquid polymer used as a a water-repellent synthetic resin varnish and barrier coating.

Conically shaped devices used in conjunction with polycapillary optics to collimate and guide divergent x-rays.

Members of a class containing around 10,000 species of marine worms having well-defined segmentation of the body, differentiated head with eyes, two sexes, and swimming appendages bristles, including rag worms, lugworms, bloodworms, sea mice, and others.

Façades and other exterior walls having an overall design, such as stripes or geometric patterns, comprising stones of contrasting colors. Examples are the distinctive polychrome façades that typify Tuscan architecture.

Buildings that house clinics treating diseases and injuries of many sorts, offering broad general care that is usually on an outpatient basis. Polyclinics include hospital outpatient departments at a general practitioner health center or hospital in an urban or town environment, as well as facilities attached to major factories or other work places. They often contain reception and waiting rooms, a registration desk, consulting and treatment rooms, a pathological laboratory, X-ray facilities, physiotherapy areas, and small operating theaters.

Any of a class of low molecular-weight synthetic varnish resins, also known as ketone resins, composed of polymerized cyclohexanone and/or methyl cyclohexanone and widely used for picture varnishes.

Refers to polyester polymers used as fibers woven into fabrics.

A range of biaxially drawn films made from polyethelene terephthalate polymer, created by extruding the polymer through a slot die, then drawing it in two directions at right angles to orient the molecules in the plane of the film, then held under tension and heat set. Polyester film has great strength, dimensional stability, and resistance to chemicals, and has been used in a variety of industrial applications, as a base for motion picture film, videotape, and audio tape, and archival housing for documents, laminate, and many other uses.

A synthetic fabric with a thick, soft pile, used for outer clothing and blankets. Originally developed in 1979 by Malden Mills, a Massachusetts textile maker. Made from polyethylene terephthalate (PET), it has been adopted as an alternative to wool in applications that require warmth. It can be made from fibers recycled from plastic PET bottles.

A planographic printing technique first developed as a means for creating inexpensive offset prints. It was subsequently adopted as an artist's printmaking technique mimicing traditional lithography based on the resistance of oil and water. Images can be created on specially made polyester plates by direct drawing with waterproof materials or printing the plate on a laser printer. The imaged plate is then washed with a wetting solution and charged with an oil-based ink. These are then run though a lithographic or etching press in the conventional way.

Any of a family of water-soluble polymers that range in viscosity from liquid to wax-like solid. They are present in organic solvents for dyes and resins; and used as wetting agents, emulsifiers, and plasticizers.

Thermoplastic polymer of the polyester family made by condensing ethylene glycol and terephthalic acid. It is used to make textile fibers, disposable beverage bottles, photographic film, and magnetic recording tape. Polyethylene terephthalate (PET) was the first commercially marketed polyester, sold as Dacron (TM) in the U.S.

A synthetic wax made by catalytic polymerization of low molecular weight, high-density ethylene. It may be used as a reversible protective coating in many applications including the conservation of outdoor sculpture.

Nombre comercial para una serie de rellenos de celulosa miscibles con agua utilizados en la conservación para la restauración de materiales como mármol, alabastro y cerámica.

Embodying multiple genders.

Churches having a centralized plan that is polygonal in shape.

Forts having a polygonal shape, which varied according to the site and requirements. Although they existed by the middle ages, prime examples of polygonal forts were those constructed resist the fire of rifled artillery and heavy mortars in the late 18th through 19th centuries.

Building material comprising uncoursed masonry used in the ancient Mediterranean world. Laid up of large blocks of stone in rough polygonal shapes, often fitted together without mortar. Similar to "cyclopean masonry," but with more precise fitting of stones due to the straight hewn sides.
