  • Laboratory experiments were performed to investigate the effects of various factors on the phosphorus removal by electrolysis with aluminium electrodes. The efficiency of phosphorus removal increases with increasing of voltage applied, surface area of electrodes and electrolyte concentration, and decreasing of electrode distance. The phosphorus removal was not affected by the connection number of an electric circuit. The amount of aluminium ion eluted from electrodes according to Faraday's law was 4.47 mg and the A/P mole ratio was 2.14 at the electric current value of 20 mA.

  • 폴리머는 20세기 중반부터 그 사용량이 급격히 늘어나고 있고 또한 사용범위도 매우 광범위해진 중요한 재료이다. 석유화학공업의 발달과 더불어 초기의 고분자공업은 범용수지의 생산에 주로 의존하였으나 최근에는 용도가 다양해지고 기능화 되면서 소량, 고가의 기능성 고분자재료들이 많이 나타나고 있다.(중략)

  • An adaptive on-line optimization method has been applied to test the ability to maximize the cellular productivity of a continuous methylotroph culture system which was simulated by a variable yield Monod-type model. Optimum dilution rate and productivity were successively obtained and maintained at all times by the algorithm that utilizes steepest descent technique as optimization method and recursive least-square method with forgetting factor as dynamic model identification.
