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...

Stainless steel pipe with fine hole and long size has recently been needed for the flow line of pure gas and liquid, which is used in the field of precision machinery. Inner wall polishing of the capillary is very difficult by ordinary finishing methods. High speed slurry flow finishing method developed by authors has been proved to have excellent polishing performance, but it has been needed a...

Understanding P sorption from animal manures is essential to formulate best management practices with regard to land application of manure from the standpoint of crop production and environmental quality. Little research has focused on the construction of P sorption isotherms where the P source is manure. The objectives of this study were to: (i) develop a procedure to characterize how inorgani...

AND CONCLUSIONS Chemical Mechanical Planarization (CMP) must continuously improve to meet the stringent requirements of next generation IC device manufacturing. Precision flow control of CMP slurry is critical to achieving a repeatable planarization process, minimizing slurry waste, and reducing cost-of-ownership (CoO). Monitoring and controlling slurry large particle concentration through filt...

Because of intensive animal farming, the problem of animal wastes disposal has become very acute in the Reunion Island, namely for liquid wastes such as pig slurry. In this paper we address the problem of determining efficient supply policies of a slurry treatment plant collectively managed by individual farmers. For this, we built a simulation model with a continuous part (i.e., slurry stocks ...

A multicomponent one-dimensional dynamic mathematical model for the reacting slurry systems with a change in gas flow rate due to the chemical reaction is developed. A change in gas flow rate caused by the chemical reaction is modeled using the overall gas mass balance. Thus, all relevant chemical species are included in the model. Linear first-order reaction kinetics is considered. The gas pha...

Bioslurry phase reactor augmented with ETP microflora was studied for the degradation of pendimethalin contaminated soil. The effect of substrate concentration on the process performance was evaluated in the slurry phase reactor operated in sequence batch mode under anoxic-aerobic-anoxic microenvironment with a total cycle period of 120 h. The performance of augmented slurry phase system was fo...

Cattle slurry was surface-applied to bare soil in two experiments in the period September­ November 1987, while in April-May 1988 two experiments were carried out in which the slur­ ry was mixed with the upper 6 an of the soil with a cultivator immediately after spreading. The 1987 experiments both lasted 18 days, the 1988 experiments 9 days. A micrometcorologi· cal technique, which did not dis...

Thermogravimetric analysis (TGA) was utilised to compare the thermal stability of pure phase change material (D-mannitol) that nano-enhanced PCM (NEPCM) (i.e., containing 0.5% and 1% multiwalled carbon nanotubes (MWCNT)). Using model-free kinetics techniques, NEPCM degradation were analysed. Three different kinetic models such as Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), Starink a...

In order to solve the bleeding problem of self-flowing tailings filling slurry with low concentration, the influences of the dosage of special additive on the bleeding rate were investigated. The improving mechanism of special additive on the bleeding of tailings filling slurry was studied by measuring the bleeding rate and compressive strength of the slurry. Also, microstruture analysis was co...
