Quantifying the particle size of intertidal sediments with satellite remote sensing in the visible light, thermal infrared and microwave spectral domain.
Influenza has increasingly become a global issue that threatens human lives worldwide. While an aerosol-type influenza vaccine has been licensed for the treatment of seasonal influenza via intranasal...
Problem statement: The aim of this study was examine the representative particle size of noncohesive sediment samples collected from different storm sewer inlets in residential catchments within Kuwai...
The estimation of the air aerosol number concentration variation was carried out in this study making use of data obtained from the Helwan, Egypt. The aerosol number concentration was determined indir...
The effects of rheological properties of the wall materials on the morphology and particle size distribution of microcapsules prepared by spray-drying were evaluated. Gelatin-sucrose (Gel-Suc), gelati...
Particle size distribution of the sample of waste sawdust and wood shavings mixtures were made with two commonly used methods of mathematical models by Rosin-Rammler (RR model) and by Gates-Gaudin-Sch...
Optical correlation technique of determining the cement particle size distribution is described. It is based on transverse coherent function measurement using a polarization transverse shearing inte...
Design/methodology/approach: In this study the effect of particle size distribution on refractory properties of ultra-low cement castables was investigated. Secar 71 cement was used as a binder. The ...
It is well known that wood species and particle size used influence the bending strength of the three-layer particleboard. The purpose of this research was to determine how the size of beech (Fagus sy...
An experimental study was conducted on the development length of a two-phase flow produced by the loading of solid particles by means of a particle feeder into air flowing through a horizontal pipe.D...
A developed overall model for sulfur self-retention in ash during coal particle combustion is presented in the paper. The total sulfur content in char, after devolatilization, is evaluated using a der...
The densification behaviour of aluminium, iron and alumina powders under cold isostatic pressing (CIP)are examined. For this purpose, a unit which can withstand up to 650 MPa pressure was designed and...
以石化柴油为参照,在发动机台架上,采用电子低压冲击仪及其附带的两级稀释系统测试了燃用柴油、甲醇柴油和生物柴油排放的不同粒径微粒的数量浓度、体积浓度,分析了发动机转速、负荷以及燃油种类对微粒粒径分布的影响。试验证明:在外特性下,柴油、甲醇柴油排放的微粒数量浓度随转速增大而增加,生物柴油排放的微粒数量浓度随转速没有明显变化规律;在2300r/min,生物柴油和柴油随负荷的减小排放的微粒数量浓度增加;标...
Hydrocracking (HC) catalysts consisting mainly of silica-alumina and a small amount of ultra stable Y type (USY) zeolite were prepared with silica-alumina powders of different mean particle sizes, an...
This study aimed to compare the physical properties of mayonnaise with its perceived texture. Model mayonnaises with the same composition were prepared under different emulsifying conditions. Perceive...
