Filtration performance of geotextiles strongly depends on their pore structure parameters, i.e. percent open area (POA), pore opening size distribution (PSD) and constriction size distribution (CSD). Current methods of determination of pore structure parameters contain inherent disadvantages whereas image analysis can be used effectively for this purpose. Two new image-based PSD and CSD determi...

The polymetallic nodules in the deep-sea multi-stage lifting motor pump will undergo repeated impeller blade impact and fragmentation, which change particle size, thereby affecting number of ores that can be recovered on surface design parameters processing equipment. A new calculation method degradation rate is proposed. model multiple impacts particles improved to quantitatively calculate fin...

The present paper examines the adsorption of water by microporous carbons containing various amounts of surface oxygen an a smaller proportion of basic centres. The modelling of water adsorption for 293 and 310 K, using variable pore size distribution (PSD), confirms that the overall type IV isotherm is the sum of a type I isotherm associated with the specific interactions, and a typ V isotherm...

Buried charges pose a serious threat to both civilians and military personnel. It is well established that soil properties have large influence on the magnitude variability of loading from explosive blasts in buried conditions. In this study, work has been undertaken improve techniques for processing pressure data discrete measurement apparatus; performed through testing truncation methodologie...

In article 2200173 by Cavus Falamaki and co-workers, an in-house nanoparticle-tracking analysis (NTA) system for the determination of particle size distribution (PSD) polydisperse suspensions transparent nanoparticles is developed. This new analytical able to measure SiO2 in water medium a down 5 nm.

Measuring sediment flux in rivers remains a significant problem in studies of landscape evolution. Recent studies suggest that observations of seismic noise near rivers can help provide such measurements, but the lack of models linking observed seismic quantities to sediment flux has prevented the method from being used. Here, we develop a forward model to describe the seismic noise induced by ...

Shank and GKAP are scaffold proteins and binding partners at the postsynaptic density (PSD). The distribution and dynamics of Shank and GKAP were studied in dissociated hippocampal cultures by pre-embedding immunogold electron microscopy. Antibodies against epitopes containing their respective mutual binding sites were used to verify the expected juxtapositioning of Shank and GKAP. If all Shank...

Mathematical descriptions of classical particle size distribution (PSD) data are often used to estimate soil hydraulic properties. Laser diffraction methods (LDM) now provide more detailed PSD measurements, but deriving a function to characterize the entire range of particle sizes is a major challenge. The aim of this study was to compare the performance of eighteen PSD functions for fitting LD...

A new technique for measuring the Particle Size Distribution (PSD) of a soil, known as Single Particle Optical Sizing (SPOS), has been evaluated. A series of tests were conducted to compare the results obtained from sieve analysis and the SPOS method. It was found that for typical laboratory sands, the SPOS method oversizes particles compared to sieving by 20-30%, as predicted by theoretical an...
