... Absorption is an important property of rocks, as it is indicative of the capacity for assimilation or incorporation of water by the stone material, which in turn may influence the durability of dimension stone in the built environment. It is strongly associated to the rock type and thus...

... Transmission of Materials , inverted wet cup vapor permeance testing, and modified ASTM long-term absorption testing. This testing protocol has measured osmotic flow rates and ASTM E96 inverted wet cup vapor permeance for a range of different waterproofing membrane types. The authors propose that this set...

... Thermal physical (thermal diffusivity and conductivity) and optical (attenuation, absorption and scattering) properties of alumina fiber insulation materials were measured. The measurements of apparent thermophysical properties are based on the method of heating of plate specimens at a constant...

... of a widely accepted method for evaluation of tissue adhesives and the availability of a family of novel absorbable tissue adhesive systems provided an incentive to develop a test method for assessing the two key parameters of candidate adhesives, namely adhesive strength and absorption. This report describes...

... This paper presents results for wet aging of five glass fiber-reinforced polymer matrix composites. Specimens were immersed in distilled water for 2 years at four temperatures (5, 20, 40, and 60°C), at both atmospheric pressure and 10 MPa hydrostatic pressure. Absorption kinetics...

... for testing the material properties in realistic moisture conditions. The objective was to analyse the moisture loads and the wetting mechanisms of horizontal EPS frost insulation. Typical wetting tests, water immersion and diffusive water vapour absorption tests, were studied and the results were compared...

... for the absorption of the masonry units and its corresponding affect on compressive strength of the test specimens. However, due to the cost, time, materials, space and laboratory ability required for this test, many times the owner or contractor opts for standard concrete cylindrical specimens cast in nonabsorbent...

... equipment for measuring spontaneous uptake of liquids by fibrous materials has been developed which allows to control the conditions for initial contact between sample and the liquid. By continuously monitoring the approach of liquid to the sample surface and mass changes due to absorption, the first...

.... The second test is based on absorption of water into the concrete surface over a four minute period. Development and field trials of the two tests are described. The tests are applicable to both horizontal and vertical surfaces. Applications for the tests include quality control of sealer application...

.... However, at the corrosion potential, another source of Δ E ( t ) and Δ C ( t ) must be proposed. It has been shown that this difference is related to the influence of an intermediate reaction species which partly blocks the hydrogen absorption under cathodic polarization and disappears at the corrosion...

... We have designed and implemented a series of investigations aimed at estimating the range and extent of gastrointestinal absorption of lead from various mineralogical matrices following oral and intravenous reference substance doses and oral test substance doses. Using pharmacokinetic...

... to which a material is exposed along with the material's spectral absorption and guantum yield coefficients. Total effective dosage has been shown to be a good predictor of human response to solar UV radiation. The mathematical basis for determining the total effective dosage, the underlying assumptions...

... This paper covers a new process that detects and locates leaks from pipelines using a patented sensor tube. The sensor tube is laid parallel to a gas or liquid pipeline to monitor for vapors from a release. The sensor tube membrane has a high permeability for vapor absorption and diffusion...

... activity of acetylcholinesterase (AchE) and microsomal fraction was used for the detection of inhibitory action of diazinon and Phase I metabolic activity of fish homogenate in vitro . Ethoxy- 14 C-labelled diazinon was used for tracing the absorption difference, as well as confirmation of the enzymatic...

... performed a polishing parameter matrix investigation to optimize fused silica (Corning 7957) surfaces for subsequent ion milling. Samples were characterized for surface scatter, surface absorption, surface roughness, subsurface damage, and laser damage as a function of mill depth. Small defects (pits) were...

... Photoacoustic spectrososcopy is used to characterize the surface absorption of polished fused silica substrates and thin films deposited on fused silica substrates. The extreme sensitivity of this technique allows measurement of surface absorptions of a few tenths of a part per million...

... Evidence is presented that confirms the role of mechanical strain in promoting surface absorption of hydrogen in two high strength steels under cathodic polarization in alkaline 3.5% sodium chloride solution. Data are reported for a 5Ni-Cr-Mo-V steel {896 MPa(130 ksi) yield strength...

... to have higher refractive indices than their evaporated counterparts. The IBD films, in general, exhibited an inhomogeneity which was the reverse of the inhomogeneity found in the E-beam films. This indicates a difference in the nucleation and growth of the films. Tantala films show an absorption band...
