badania nad przebiegiem procesu bzt sciekow wlokienniczyvh $left bracket$ studies of the bod process in textile wastes $right bracket$

changes in the biochemical oxygen demand in dye wastes of the synthetic fiber industry are discussed as a function of the reaction, the temperature, the quantity of detergent, and the quantity of inoculant material. an attempt is made to establish the effect of these factors on the bod index in order to obtain reproducible values of this ..

coupling agents in wood fibre-reinforced cement composites

in the reported experiments, the effects of surface treatment of discrete wood fibers incorporated into cement have been studied by measuring the fracture energy and flexural strength of the derived composite materials. the results of this investigation confirm that the mechanical performance of a wood fiber reinforced cement composite ca..

evaluation of metal mirrors for high power applications by multithreshold damage analysis

development of damage-resistant mirrors for high power, pulsed infrared laser applications depends on accurate identification of dominant failure modes and their origin. previous work indicates that metal surfaces are usually subject to plastic deformation, pitting, or other effects which may degrade reflective properties long before lase..

chemical modification of polymers with flame-retardant compounds

this comprehensive, literature-based, review of the fireproofing of natural and synthetic polymers and related products is presented in 13 parts. they include $em dash$ introduction, definition of terms (thermal degradation and combustion, chemical modification, polymer flammability, test procedures); scope of the review; pyrolysis, therm..

micromachining applications for icf target fabrication

micromachining techniques used in inertial confinement fusion (icf) target fabrication encompass laser drilling, single point diamond turning, and plasma as well as chemical etching. these techniques have been developed to produce target components with tolerances and surface finishes in the micron to submicron regime an examination is ma..

laser-interferometer position feedback for precision machine tools

diamond turning of off-axis parabolic mirrors to provide high-quality turning and focusing optics for the los alamos scientific laboratory's laser-fusion research. these mirrors are fabricated on a large machine tool that incorporates lasers, air bearings, and linear-motor slide-drives to meet the part specifications of 0. 63 $mu$ m (25 $..
