We study the effective polarity of an air/liquid-mixture interface by using interface-selective heterodyne-detected electronic sum frequency generation (HD-ESFG) and vibrational sum frequency generation (HD-VSFG) spectroscopies. With water and N,N-dimethylformamide (DMF) chosen as two components of the liquid mixture, the bulk polarity of the mixture is controlled nearly arbitrarily by the mixi...

We discuss the dynamic behavior of two silica models, the BKS model (by van Beest, Kramer, and van Santen) and the WAC model (by Woodcock, Angell, and Cheeseman). Although BKS is considered the more realistic model for liquid silica, the WAC model has the unique property that it is very close to having a liquid-liquid critical point (LLCP), and this makes it particularly useful in studying the ...

background : gestational trophoblastic neoplasia (gtn) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. many attempts have been made to improve follow-up procedures, but no studies have evaluated human chorionic gonadotrophin (hcg) as a post treatment indicator. thus we aimed to know β-hcg variability in post treatment pregnancies.   method...

. A technique for hydrodynamic experiments has been developed to study a disk atomizer in rotary mass transfer apparatus. In the course of experiments, indicator method determines average residence time liquid on contact device, volume retained diameter droplets formed, and height gas-liquid layer

State University of New York at Stony Brook 2A two-level factorial design can be uniquely represented by a polynomial indicator function. Therefore, properties of factorial designs can be studied through their indicator functions. This paper shows that indicator function is an effective tool in studying two-level factorial designs. Indicator function is used to generalize aberration criterion o...
