Diffusion of feed spray in fluid catalytic cracker riser
Authors: Fan Yiping , E Chenglin , Shi Mingxian , Xu Chunming , Gao Jinsen , Lu Chunxi 
Published: August 2009

AbstractFor fluid catalytic cracker (FCC) riser reactor, the diffusion pattern of feed spray and the flow features of catalysts in the feed injection zone were investigated in a cold‐riser model that is made of 186‐mm ID plexiglass pipe. In the feed injection zone, when a feed spray is introduced into the riser, a secondary flow of spray will occur. The secondary flow extends at first and then merges into the mainstream of spray. The occurrence of the secondary flow enhances the mixing of catalysts with feed. However, the extension of the secondary flow causes a violent catalyst backmixing; it is believed to be harmful to FCC reaction. The generation of the secondary flow of feed spray was theoretically analyzed by using the Kutta‐Joukowski Lift Theorem. Furthermore, a FCC feed nozzle, which can control/utilize the secondary flow in riser, was proposed. The effects of the nozzle used in some commercial FCC units are quite desirable. © 2009 American Institute of Chemical Engineers AIChE J, 2009

Published: August 2009

AbstractA series of triterpene endoperoxides was synthesized and screened for antitumor activity in a panel of 15 human cancer cell lines by a sulforhodamine‐B (SRB) assay. The compounds induce apoptosis and show excellent antitumor activity.
Assessing the scholarly impact of information studies: A tale of two citation databases—Scopus and Web of Science
Authors: Meho Lokman I. , Sugimoto Cassidy R. 
Published: August 2009

AbstractThis study uses citations, from 1996 to 2007, to the work of 80 randomly selected full‐time, information studies (IS) faculty members from North America to examine differences between Scopus and Web of Science in assessing the scholarly impact of the field focusing on the most frequently citing journals, conference proceedings, research domains and institutions, as well as all citing countries. Results show that when assessment is limited to smaller citing entities (e.g., journals, conference proceedings, institutions), the two databases produce considerably different results, whereas when assessment is limited to larger citing entities (e.g., research domains, countries), the two databases produce very similar pictures of scholarly impact. In the former case, the use of Scopus (for journals and institutions) and both Scopus and Web of Science (for conference proceedings) is necessary to more accurately assess or visualize the scholarly impact of IS, whereas in the latter case, assessing or visualizing the scholarly impact of IS is independent of the database used.
Image use within the work task model: Images as information and illustration
Authors: McCay‐Peet Lori , Toms Elaine 
Published: August 2009

AbstractWith increasing sophistication in technology has emerged a growing interest in accessing images for personal and work purposes. In this research we investigated the use of images as data—for the information contained within the image, and as an object to illustrate. Thirty journalists and historians from academic and professional work settings were interviewed using a series of semistructured questions regarding how they use images (for information or for illustration) and the types of image attributes used to describe an appropriate image for their work. This was done within the context of a work task model used by this group to understand how images are used throughout the process of completing a typical written work task. Findings suggest that the stage of the work task process has a significant impact on how the image is used (information or illustration). Participants use as many descriptive as conceptual image attributes to locate an image, but, interestingly, there are no significant differences according to use for information or illustration purposes. This study increases our understanding of the function of images in the written work task process, and provides new knowledge about the conceptual and descriptive attributes that are most valued.
Guest‐Directed Supramolecular Architectures of {W36} Polyoxometalate Crowns
Authors: McGlone Thomas , Streb Carsten , Long De‐Liang , Cronin Leroy 
Published: August 2009

AbstractThe {W36} isopolyoxotungstate cluster provides a stable inorganic molecular platform for the binding of inorganic and organic guest molecules. This is achieved by a binding pocket formed by six terminal oxo ligands located in the central cavity of the all‐inorganic cation binding host. Previously it was shown that the cluster can specifically bind primary amines and importantly, functionalized diamines through a combination of electrostatic and hydrogen bonding interactions. Here we transform this assembly strategy to utilize the binding of long‐chain alkyldiammonium guest cations to physically define the supramolecular structure of the clusters with respect to each other and demonstrate the structure direction as a function of alkyl chain length. The systematic variation of the chain length gives access to five supramolecular assemblies which were all fully characterized using single crystal XRD, TGA, 1H NMR, and elemental analysis. In compound 1, diprotonated 1,8‐diaminooctane molecules link the {W36} clusters into infinite 1D zigzag chains, whereas compounds 2 and 3 feature trimeric {W36} assemblies directly connected through protonated 1,9‐diaminononane (2) or 1,10‐diaminodecane (3) linkers . Compound 4 contains dumb‐bell shaped dimeric units as a result of direct center‐to‐center linkages between the {W36} clusters formed by protonated 1,12‐diaminododecane. In compound 5, triply protonated bis(hexamethylene)triamine was employed to obtain linear 1D chains of directly connected {W36} cluster units.
Synchronous collaboration of virtual and remote laboratories
Authors: Jara Carlos A. , Candelas Francisco A. , Torres Fernando , Dormido Sebastién , Esquembre Francisco 
Published: August 2009

AbstractVirtual and remote laboratories(VRLs) are e‐learning resources which enhance the accessibility of experimental setups providing a distance teaching framework which meets the student's hands‐on learning needs. In addition, online collaborative communication represents a practical and a constructivist method to transmit the knowledge and experience from the teacher to students, overcoming physical distance and isolation. Thus, the integration of learning environments in the form of VRLs inside collaborative learning spaces is strongly desired. Considering these facts, the authors of this document present an original approach which enables user to share practical experiences while they work collaboratively through the Internet. This practical experimentation is based on VRLs, which have been integrated inside a synchronous collaborative e‐learning framework. This article describes the main features of this system and its successful application for science and engineering subjects. © 2009 Wiley Periodicals, Inc. Comput Appl Eng Educ 20: 124–136, 2012
