Oil pipeline Supervisory Control and Data Acquisition (SCADA) systems monitor and help control pipes transporting both crude and refined petroleum products. Typical SCADA system architectures focus on centralized data collection and control – however, this system has vulnerabilities that decrease the overall security of the system, especially for an oil pipeline SCADA. Service-oriented architec...

Direct tabletting technique is the modern and the most efficient process used in tablet manufacturing which has been successfully used for various drugs. But the process strongly depends upon the quality of the crystals used. For improvement of direct compression properties of different poorly soluble drugs Kawashima and their coworkers developed the spherical crystallization technique in 1986,...

Objective(s):This study dealt with the wet agglomeration process in which a small quantity of binder liquid was added into a suspension of crystals, directly in the stirring vessel where the crystallization took place. The purpose of this investigation was evaluation of the effect of temperature on the agglomeration process in order to gain insight into the mechanism of the formation of the agg...

We demonstrate the photophoretic trapping of more than several hundreds of absorbing particles by tapered-ring optical traps diffracted from a circular aperture. The experiments with different laser powers show the influence of air flow acting on particles. Three kinds of particles with different densities (about 1~7 g/cm(3)) and different shapes (spherical, non-spherical) can be trapped. The n...

Nimodipine (NMP), a Ca channel blocker, has a low oral bioavailability due to poor solubility and insufficient dissolution rate. In order to improve the same, various techniques were employed viz., evaporative precipitation into aqueous solution (EPAS), spherical agglomeration (SA) and solid dispersion using solvent evaporation and meltmixing. Formulations so prepared were characterised by diff...

Nanoparticles of transition metal dichalcogenides (TMDC) have been known to reduce friction and wear when added to oil-type liquid lubricants. Aggregation limits the ability of the nanoparticles to penetrate into the interface between the two rubbing surfaces—an important factor in friction reduction mechanisms. Doping has been successfully used to reduce agglomeration, but it must be done in t...

Environmental protection has become the focus of world-wide research in the gold mining industry and favours the development of environmentaly sound processes, such as the Coal Gold Agglomeration (CGA) process, which is an alternative to existing gold processing methods, such as cyanidation and mercury amalgamation. The CGA process was developed and patented by the British Petroleum (BP) resear...
