The vapor-liquid equilibria (VLE) at high pressure of the binary systems, carbon dioxide-hydrocarbon and methane-hydrocarbon are calculated by using the equations of state given by Peng-Robinson and Soave that are even simple but, comparatively, able to predict accurately. The interaction parameters included in the equations of state are shown in figures. It is known that the parameters are dependent of the characteristic temperature defined in this text. As the same calculation procedure for binary systems, parameters are obtained from the binary VLE data of the systems that are composed of each component of ternary systems, CO₂-CH₄-C₂??, CO₂-C₂H₄-C₂??, N₂-Ar-O₂ and N₂-Ar-CH₄. For the prediction of the VLE of the ternary systems, the parameters are used and the results are compared with the observed data. The mixing rule proposed by Chueh and Prausnitz[3]is used for the systems.

This paper deals with the tapped time delay circuit with SCF(Swiched Capacitor Filters). This filter is composed fo lossless discrete integrator and the SCF has 2-phase clocks. Experimental results have shown that telephone signals (0~4kHz) could be delayed in the range of sampling frequency 80kHz.But above the range, operational amplifiers and analog switchs have been difficult in the normal operating condition

The o/w microemulsions containing β-carotene were made from 3 or 5% w/w oil(soybean oil, cottonseed oil and isopropyl myristate) and 15, 20 or 25% w/w nonionic surfactant (Cremophor EL, Cremophor RH 40 and Brij 97/Pluronic F-68(2:1 w/w). They are characterized by particle size distribution, surface tension and viscosity. Also, stability study was done by antioxidant, long-term storage for 6 months.
First Report of Zucchini yellow mosaic virus on Hollyhock (Althaea rosea)

This study was conducted to determine the causal virus that naturally infected hollyhock (Althaea rosea) plant showing mild mosaic symptom in 1999. Flexuous virus particles were found in the cytoplasm of plant tissue from infected hollyhock under transmissible electron microscopy. A virus from the genus Potyvirus under the family Potyviridae was isolated and was maintained on Chenopodium quinoa for three passages. Chlorotic local legions were used to inoculate 20 species of indicator plants. The virus infected all the tested cucurbit plants, but failed to infect Nicotiana benthamiana. Based on the host range test and RT-PCR analysis, the potyvirus was identified as a strain of Zucchini yellow mosaic virus-A (ZYMV-A), one of the major pathogens of cucurbits. Infectivity analysis showed that ZYMV-A induced faster systemic symptom than ZYMV-Cu on squash and other cucurbit plants, suggesting that ZYMV-A was a more severe strain. To better characterize ZYMV-A, Western blot assay was carried rout to the coat protein (CP) of the virus using ZYMV-specific antiserum with ZYMV-Cu and other potyviruses. The CP of the virus reacted strongly with the antiserum against ZYMV, and other tested antisera did not react with the CP of ZYMV-A. Results strongly suggest that the potyvirus infecting hollyhock was a novel strain of ZYMV. This is the first report on ZYMV as the causal virus infecting hollyhock in Korea.
