Marine diesel engine lubricating oil after long-term use, due to pollution and chemical activity, internal impurities increased, lubrication effect gradually deteriorated. The purification device based on balanced charge agglomeration (BCA) can realize the on-line of oil. In order further improve efficiency, a control system PLC is designed in this paper. consists complex electromechanical inte...

ABSTRACT It is known that various plants have purification ability for indoor air pollutants. In this paper the purification mechanism of foliage plant was investigated by analyzing bioelectrical potential. It was first shown that the air purification ability of a plant depends on various environmental conditions, especially on light irradiation. It was then clarified that the bioelectrical pot...

Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column e...

Simulation of a process and analysis of its resulting data in both dynamic and steady-state conditions are fundamental steps in understanding the process in order to design and efficient control of system as well as implementing operational cost reduction scheme. In the present paper, steady and unsteady state simulation of Amir Kabir1, 3 butadiene purification units has been done by using Aspe...

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

DNA purification is a routine procedure in most plant laboratories. Although different kits are available in the market allowing convenient DNA purification, the cumulative cost of purchasing multiple kits for a laboratory can be staggering. Here, we describe a protocol using homemade silicon dioxide matrix for DNA purification from Escherichia coli and Agrobacterium tumefaciens cells, PCR and ...
