background and objectives: pseudomonas aeruginosais an important opportunistic pathogen. the mucoid strains of p. aeruginosa produce hyper viscous substances consisting mainly of alginate which have important roles in formation of biofilm.we investigated the effect of essential oil of matricaria chamomilla l. on biofilm production in p. aeruginosa. material and methods: p. aeruginosa 8821m was ...

Palm oil mill effluent (POME) is an important source of inland water pollution when released into local rivers or lakes without treatment. In the process of palm oil milling, POME is generat‐ ed through sterilization of fresh oil palm fruit bunches, clarification of palm oil and effluent from hydro-cyclone operations [Borja et al.,1996a]. POME is a viscous brown liquid with fine suspended solid...

Researchers in China have tended not to distinguish between conventional and unconventional oil, leading to inaccuracies in their estimates of future oil production. The purpose of this paper is to make an accurate estimate of the pattern of China’s future oil production, by properly distinguishing between these oil types. We make our analysis by treating conventional oil as a single category, ...

Automatic focusing of microscope images is an essential part of modern high-throughput microscopy. This chapter describes implementation of a robust autofocus system appropriate for using either air or oil immersion objectives in robotic imaging. Both hardware and software algorithms are described, and caveats of using viscous immersion media with multifield scanning are detailed.
