E-Companion of “Asset Pricing with Spatial Interaction” by Steven Kou, Xianhua Peng, and Haowen Zhong The E-Companion is organized as follows. Section EC.1 presents the mean-variance analysis with spatial interaction. Section EC.2 gives the proof of the S-CAPM theorem when there is a risk-free asset and when there is no risk free asset. The proof of the S-APT theorems is given in Section EC.3. ...

in this study, mathematical modeling of hot air-drying of thin-layer papaya (carica papaya l.) slices with 5±1 mm thickness pretreated in osmotic solution (50% sucrose) was investigated. thin-layer drying was conducted under three different drying temperatures of 40, 50 and 60 °c at a constant air velocity of 0.9±0.1 m/s and absolute humidity of 0.6 ± 0.02 g of water/kg of dry air. it was found...

In the present study combined infrared and hot air dryer to dry a thin layer of pomegranate seeds. Three different levels power, namely: 200, 250 300 W three exposure distance between heater samples dying are 20, 15 10 cm with temperature 40 oC velocity 1.5 m/s were studied. Drying time as affected by power distance, compatibility experimental data some drying models, effective diffusivity Deff...

phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between oil-in-aqueous dispersion and aqueous-in-oil dispersion. a theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. experimental data from the literature were used to validate the model and results were compa...
