"Integrating Faith and Learning at a Private Christian University in Nigeria: Patterns of Institutionalization"Olaore, Israel Bamidele; Rhoades, Gary; Cheslock, John; Maldonado-Maldonado, Alma (The University of Arizona., 2007)Institutionalization of curricular or pedagogical innovation or reform occurs at three different levels in an organization, the regulative institutionalization which occurs as compliance by expediency, normative institutionalization which occurs as compliance by moral or legal appropriateness and cognitive institutionalization which occurs as compliance by conceptual correctness. The cognitive level is most the desirable because at that level the values and norms of the organization are manifested in the beliefs and behaviors of individuals in the organization.This research study examined the patterns of institutionalization of integration of faith and learning as a curricular and pedagogical model among faculty members at a private Christian liberal arts university in Nigeria, West Africa. Five patterns of integration of faith and learning emerged from the study compared to eight patterns of institutionalization that emerged in a similar study of four religious research universities in the United States by the team of Ream, Beaty and Lyon (2004). The findings suggest that the level of institutionalization manifested and perceivable in the Nigerian study is at the regulative institutionalization level due to the fact that the beliefs and the behaviors of the faculty members are non-congruent to the expected beliefs and behaviors compatible with the institutionalization of the integration of faith and learning curricular and pedagogical model. Even though the 'fear of God' emerged as one of the dominant themes articulated by some of the faculty members in the study, four other emergent themes articulated the need to find a balance between religious integration and academic excellence. The findings suggest Seventh-day Adventists faculty members struggle between the need to subscribe to the fear of God as a measure for integration and the need to maintain a separation between faith and learning for objectivity in the academy. Being a Seventh-day Adventist male lecturer over the lecturer II rank was found to be a dominant factor in the institutionalization of the integration of faith and learning curricular model at a regulative level at the institution in the study.
SPACE COMMUNICATION DEMONSTRATION USING INTERNET TECHNOLOGYIsrael, Dave; Parise, Ron; Hogie, Keith; Criscuolo, Ed; National Aeronautics and Space Administration; Computer Sciences Corp (International Foundation for Telemetering, 2002-10)This paper presents work being done at NASA/GSFC by the Operating Missions as Nodes on the Internet (OMNI) project to demonstrate the application of Internet communication technologies to space communication. The goal is to provide global addressability and standard network protocols and applications for future space missions. It describes the communication architecture and operations concepts that will be deployed and tested on a Space Shuttle flight in July 2002. This is a NASA Hitchhiker mission called Communication and Navigation Demonstration On Shuttle (CANDOS). The mission will be using a small programmable transceiver mounted in the Shuttle bay that can communicate through NASA’s ground tracking stations as well as NASA’s space relay satellite system. The transceiver includes a processor running the Linux operating system and a standard synchronous serial interface that supports the High-level Data Link Control (HDLC) framing protocol. One of the main goals will be to test the operation of the Mobile IP protocol (RFC 2002) for automatic routing of data as the Shuttle passes from one contact to another. Other protocols to be utilized onboard CANDOS include secure login (SSH), UDP-based reliable file transfer (MDP), and blind commanding using UDP. The paper describes how each of these standard protocols available in the Linux operating system can be used to support communication with a space vehicle. It will discuss how each protocol is suited to support the range of special communication needs of space missions.
THE HYDRODESULFURIZATION OF DIESEL FUEL TO MEET NEW EPA REQUIREMENTSOgden, Kim; Mares-Davila, Fausto Israel; Green, Jason; Terashima, Jun; Omotinugbon, Toluwani (The University of Arizona., 2016)In December 1, 2010 the EPA reduced the allowable sulfur content in diesel fuel to 15 ppm, which is now known as ultra-low sulfur diesel (ULSD). In order to reach the 15 ppm sulfur maximum, the hydrodesulfurization unit in many refineries had to be upgraded. The group has been tasked with developing an upgrade catalytic hydrodesulfurization unit for a refinery in the Delaware Valley that can treat 35,000 barrels per stream day (BPSD) of liquid feedstock containing 1.9 wt % sulfur. Performance data from the existing catalytic hydrodesulfurization unit was used to predict the performance of the upgraded unit. ChemCAD software was used for the process calculations and the feed was modeled using boiling curve data. The desulfurization reaction kinetics were based on the reduction of dibenzothiophene. The project goals are to achieve a 99% recovery of diesel fuel while reducing the sulfur content below 15 ppm. The liquid feedstock will be run through a packed bed reactor filled with CoMo/Al2O3 catalyst where the sulfur compounds will react with hydrogen gas to form hydrogen sulfide gas. An amine contactor will be used to remove sour gas from the recycle hydrogen stream and a distillation column will produce diesel.
