Many microorganisms fail to degrade pollutants when introduced in different natural environments. This is a problem in selecting inocula for bioremediation of polluted sites. Thus, a study was conducted to determine the success of four inoculants to degradep-nitrophenol (PNP) in lake and industrial wastewater and the effects of organic compounds on the(More)
Cyclic nitramine hexahydro-1,3,5-trinitro-s-triazine (RDX), is an important energetic ingredient for propellants and explosives. To understand RDX explosive nature, the molecular structure needs to be examined in detail. Solid state RDX exist as three polymorphs: α, β and γ. The α-form is the stable polymorph at room temperature with Cs symmetry,(More)
Two indigenous and one non-indigenous bacterial strains were evaluated for their ability to degrade p-nitrophenol (PNP) in pure culture. When these bacterial strains were inoculated into industrial wastewater to enhance the degradation of PNP in the presence or absence of glucose, all three strains degraded 20 mg/l of PNP with or without added glucose. With(More)
The introduction of robotic medical assistance in biopsy and stomach cavity exploration is one of the most important milestones in the field of medical science. The research is still in its infancy and many issues like limitations in dexterity, control, and abdominal cavity vision are the main concerns of many researchers around the globe. This paper(More)
In this research, an evolutionary genetic algorithm based approach is proposed for designing independent machine cells in cellular manufacturing in the presence of operation based alternative process plans for parts. Manufacturing parameters, such as production volume, usage factor for process plans, machine flexibility and cell size and machine-operation(More)
Endoscopes have been in use for many procedures including limited surgery. A very common application of endoscopes been used in surgery is biopsy. However present Endoscopes has certain limitations such as restricted degrees of motion of tool leading to poor manipulation of tissues, limited visualization of surgical field, increased sensitivity to hand(More)
