Do People Who Identify As Popular Become Popular In A New Network? A 9-Month Longitudinal Network Analysis, Christopher J. Carpenter, Xun Zhu, Rachel A. Smith

Communication Faculty Publications

Although scholars have argued that people actively shape and reshape their social networks (e.g., Parks, 2016), this aspect of relational development has received little attention. This study sought to determine if people’s self-perceptions of interpersonal communication skills translated into behavior that led to relationship formation in a new network. A 9-month longitudinal social network analysis (N = 94) of the residents of a first-year university residence hall using Facebook tie data was conducted to assess network changes. Results indicate that both self-perceived network centrality in a hypothetical friendship sociogram (Smith & Fink, 2015) and self-reported connector scores (Boster et al., …

Simultaneous High-Temperature Gas Chromatography With Flame Ionization And Mass Spectrometric Analysis Of Monocarboxylic Acids And Acylglycerols In Biofuels And Biofuel Intermediate Products, Gana Flanagan, Anastasia A. Andrianova, Jana Casey, Eric Hellrung, Bonnie A. Diep, Wayne Seames, Alena Kubatova

Chemistry Faculty Publications

Triacyl-, diacyl- and monoacylglycerols (TAGs, DAGs, MAGs) along with monocarboxylic acids (MCAs) are intermediate products in many triacylglycerol oil-to-biofuel conversion pathways. Accumulation of these compounds leads to poor biofuel characteristics and may result in fuel system damage. We developed a method for simultaneous identification and quantification of a wide range of MCAs (C4-C18), MAGs, DAGs, and TAGs. The method is based on trimethylsilylation followed by high temperature GC with programmed temperature vaporizer (PTV) injection coupled to parallel FID and MS detectors (HTGC-FID/MS).

To minimize the discrimination of both low and high molecular weight species typically occurring on the injector, we …

Geomechanical Upscaling Methods: Comparison And Verification Via 3d Printing, Lingyun Kong, Mehdi Ostadhassan, Siavash Zamiran, Bo Liu, Chunxiao Li, Gennaro G. Marino

Petroleum Engineering Faculty Publications

Understanding geomechanical properties of rocks at multiple scales is critical and relevant in various disciplines including civil, mining, petroleum and geological engineering. Several upscaling frameworks were proposed to model elastic properties of common rock types from micro to macroscale, considering the heterogeneity and anisotropy in the samples. However, direct comparison of the results from different upscaling methods remains limited, which can question their accuracy in laboratory experiments. Extreme heterogeneity of natural rocks that arises from various existing components in them adds complexity to verifying the accuracy of these upscaling methods. Therefore, experimental validation of various upscaling methods is performed by …
