A scheme for carrying out numerical simulation of a multistage mass separator is described. The results of a calculated solution are summarized for the design of a high resolution separator for purifying beams at the isobaric level.

This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m at atmospheric pressure and room temperature. The experimen...

The control of pain during orthodontic treatment is of vital interest to both clinicians and patients. Surprisingly, there has been limited research into the control of orthodontic pain, and there is no standard of care for controlling this discomfort. The purpose of this study was to compare the effectiveness of preemptive ibuprofen therapy, postoperative ibuprofen therapy, and a combination o...

For a connected graph, a vertex separator is a set of vertices whose removal creates at least two components. A vertex separator S is minimal if it contains no other separator as a strict subset and a minimum vertex separator is a minimal vertex separator of least cardinality. A clique is a set of mutually adjacent vertices. A 2-tree is a connected graph in which every maximal clique is of size...

Plastics recycling has become a key industry in developed countries, to reduce ecological damage and save non-renewable resources. This paper discusses the concept design of electrostatic separator as test bench for separation different plastics applications. In automotive process, all these waste materials must be processed further re-entering cycle or thermal utilization. The following applic...

The aim of this study was to investigate and analyze the impact selected parameters during tribocharging process shredded poly(ethylene terephthalate) (PET) high-density polyethylene (PE-HD) plastics on accumulated electric charge electrostatic separation effectiveness. accumulation surfaces polymer particles as a result their circular motion forced by airflow cyclone container investigated. ma...

Partition curves are widely used to determine the spiral separator efficiency. In this work, the partition curves were used in order to investigate the particle transportation to concentrate and tailing streams. Simulation of fine particle removal using the size-by-size partition curves showed that the recovery of gangue particles to concentrate can decrease 8.7%. It also showed that the recove...

Due to the demand for next-generation green wearable and flexible energy storage devices, gel-based electrolytes are attracting much attention as a key part of this system, but existing materials problematic because their low performance. It is necessary maintain function material by allowing it be bent in form amorphous gels, easily manufactured large quantities without toxic chemical binders ...

Two challenges for improving the performance of air cathode, single-chamber microbial fuel cells (MFCs) include increasing Coulombic efficiency (CE) and decreasing internal resistance. Nonbiodegradable glass fiber separators between the two electrodes were shown to increase power and CE, compared to cloth separators (J-cloth) that were degraded over time. MFC tests were conducted using glass fi...
