Homogeneous nucleation and droplet growth in nitrogen
A one dimensional computer model of the homogeneous nucleation process and growth of condensate for nitrogen flows over airfoils is developed to predict the onset of condensation and thus to be able to take advantage of as much of Reynolds capability of cryogenic tunnels as possible. Homogeneous nucleation data were taken using a DFVLR CAST-10 airfoil in the 0.3-Meter Transonic Cryogenic Tunnel and are used to evaluate the classical liquid droplet theory and several proposed corrections to it. For predicting liquid nitrogen condensation effects, use of the arbitrary Tolman constant of 0.25 x 250 billionth m or the Reiss or Kikuchi correction agrees with the CAST-10 data. Because no solid nitrogen condensation were found experimentally during the CAST-10 experiments, earlier nozzle data are used to evaluate corrections to the classical liquid droplet theory in the lower temperature regime. A theoretical expression for the surface tension of solid nitrogen is developed

Using Focus Groups and Correspondence Analysis to Explore the Relationship Between Millennials\u27 Online Behavior and Their Opinions of Online Reviews
Consumer decision-making regarding a purchase is usually influenced by feedback received from other people in addition to prior experiences/beliefs/attitudes and marketer dominated information. Such diverse sources of influence are collectively referred to as the influence mix (Simonson and Rosen 2014). Of the different sources in the influence mix, word-of-mouth (i.e., feedback received from other people) is one of the most impactful sources of information (Duan, Gu, and Whinston 2008). With the advent of e-tailers on the Internet, the influence of word-of-mouth communication has grown significantly in the form of online consumer reviews (Schindler ad Bickart 2012). Research has shown that online reviews significantly influence consumer purchase decisions (see, for example, Chevalier and Mayzlin 2006; Senecal and Nantel 2004). Further, according to Zhu and Zhan (2010), 24% of Internet consumers avail themselves of online reviews before buying an offering offline; additionally, the authors note that an increasing number of firms persuade consumers to spread word of their offerings online
