philippines: industrial development strategy and policies

the industrial sector mission which visited the philippines in february 1979 dealt primarily with industrial policies and incentives, with a view to exploring ways in which the country can better achieve its objectives of broader and more rapid industrial growth, employment creation, export development, regional dispersion and stronger te..

seamless collapsible fuel tanks

twenty-three by twenty foot (lay flat) pieces of tubular fabric were coated with polyurethane and fabricated into two 7500-gallon fuel tanks. the tanks were shipped to arizona for filling and exposure testing. (author)

instrument for automated measurement of the angles of cut of doubly rotated quartz crystals,

the development of an automated x-ray orientation system for accurate measurement of the angles of cut of doubly rotated quartz crystal plates is described. our goal is to develop a prototype instrument capable of determining the conventional phi and theta angles to 4 arc-seconds reproducibility and 10 arc-seconds absolute accuracy for th..

wound healing: biochemical pathways and in vivo studies

the insoluble collagens from connective tissue experimentally induced by rat, were analyzed for amino acid composition. essentially no differences were observed, the comparative values for these species being similar. in the rat it was found that these tissues contained three classes of heteropolysaccharides in a complex mixture of glycos..

wound healing: biochemical pathways and in vivo studies

the insoluble collagens from connective tissue, experimentally induced by stainless steel mesh cylinders implanted in man, dog, and rat, were analyzed for amino acid composition. essentially no differences were observed, the comparative values for these species being similar. in the rat it was found that these tissues contained three clas..

evaluation of high-efficiency heat-transfer techniques. final report, 27 september 1978-30 september 1981

single enhanced boiling tubes perform up to an order of magnitude better than single plain tubes, depending strongly on the type of surface and physical properties and operating conditions of the liquid. it is most pronounced at low temperature differences, then decreases and eventually disappears with increase of the temperature differen..

metal loaded poly-p-xylene

inertial confinement fusion target designs frequently require hydrocarbon polymer coatings loaded with varying amounts of high atomic number materials, typically metals. in addition to the usual requirements on thickness uniformity and surface finish, the metal loading must be dispersed in the polymer matrix on a submicron scale the commo..

flammability tests for printed wiring sheet materials: assessment of several testing procedures,

a procedure is recommended for calculating the flammability index of fully etched rigid printed circuit board materials. based on two sets of round-robin tests the procedure uses a needle burner and a series of measurements after the boards had been thermally aged for the equivalent of 10 years at 70 degrees centrigrade, it was found that..
