Instruments for optical fiber measurements, such as the Fiber Quality Analyzer (FQA), are widely used to measure various properties of pulp samples. For the evaluation of market pulps, the pulp properties of interest are fiber length, coarseness, and fines content. Fiber length and coarseness are often used to determine which pulps are suitable for producing particular products. The objectives ...

Fine excipient particles or 'fines' have been shown to improve the dispersion performance of carrier-based formulations for dry powder inhalation. Mechanistic formulation studies have focussed mainly on explaining this positive effect. Previous studies have shown that higher drug contents may cause a decrease in dispersion performance, and there is no reason why this should not be true for fine...

Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...

Singleand three-layer mixed hardwood oriented strandboard (OSB) with various wood fines contents and panel densities were manufactured using phenol-formaldehyde (PF) resin as binder. The effects of fines level and density on the panel properties were studied. Mathematical models based on lamination theories were used to predict properties of three-layer panels, including effective modulus (EM),...

THE effect of moisture content, fine material con­ centration and bulk density on the airflow resistance of long-grain rough rice was determined. Airflow resistance was measured at air velocities ranging from 0.013 to 0.387 mis, bulk densities from 480 to 604 kg/m3, fines concentrations from 0 to 30% and moisture contents from 12 to 24 %. Airflow resistance was accurately described by an empiri...

series of undrained monotonic triaxial tests and cone penetration tests were conducted on loose silty sand samples to study correlation between undrained shear strength of silty sands (sus) and piezocone test results. cpt tests were conducted at 27 silty sand samples in calibration chamber. the results indicate that, in low percent of silt (0-30%), as the silt content increases, the undrained s...

Unbound aggregates are the most common type of materials used for construction of the base layer of flexible pavements in Iran and worldwide. Due to the lack of binder, the performance of the compacted unbound aggregates is highly dependent on the properties of the gravel (particles remaining on sieve 4.75mm, sand (particles passing sieve 4.75mm and remaining on sieve 0....
