Chemical-mechanical separation of pig slurry into a solid fraction rich in dry matter, P, Cu and Zn and a liquid fraction rich in inorganic N but poor in dry matter may allow farmers to manage surplus slurry by exporting the solid fraction to regions with no nutrient surplus. Pig slurry can be applied to arable land only in certain periods during the year, so it is commonly stored prior to fiel...

The aim of the study was to investigate the decontamination of pig slurry containing exotic viruses of pigs, foot AND mouth disease virus (FMDV), Aujeszky's disease virus (ADV) AND classical swine fever virus (CSFV). Laboratory-scale decontamination experiments showed that FMDV, ADV and CSFV were heat inactivated in slurry within 3 min at 67 degrees C, 3 min at 62 degrees C and 3 min at 60 degr...

the aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (nepcm) slurry as a cooling fluid instead of pure fluid. a threedimensional model of a circular channel using water slurry of nepcm was developed. the results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

The slurry erosion behaviour of laser clad Fe–Cr–B–Si alloy coatings was investigated at impact angles from 30u to 90u with an increment of 15u, and compared with the slurry erosion behaviour of two laser clad carbide coatings and a non-coated substrate made of AISI 4140 steel. The Fe–Cr–B–Si alloy coatings had slurry erosion resistance. Their overall slurry erosion resistance at impact angles ...

Based on a global kinetics of direct dimethyl ether (DME) synthesis process from syngas, a steady-state one-dimensional mathematical model for the bubble column slurry reactor (BCSR) has been established. It was built on the assumption of plug flow of gas phase, sedimentation-dispersion model of catalyst grains and isothermal chamber regardless of reaction heats and rates for the design of an i...

Microbial consortia isolated from aged oil-contaminated soil were used to degrade 16 polycyclic aromatic hydrocarbons (15.72 mgkg(-1)) in soil and slurry phases. The three microbial consortia (bacteria, fungi and bacteria-fungi complex) could degrade polycyclic aromatic hydrocarbons (PAHs), and the highest PAH removals were found in soil and slurry inoculated with fungi (50.1% and 55.4%, respec...

In this paper, we present a review of the measurements that Dual Emission Laser Induced Fluorescence (DELIF) has allowed us to make over the last 8 years. We have been able to measure many features of the slurry film between the wafer and the pad during polishing while simultaneously measuring the frictional drag. In particular, we measured slurry mean residence time, slurry temperature, and th...
