Chapter 2 details the arrival of South Asian students and immigrants in Houston during the 1960s. Along with college towns and major cities across the United States, Houston was an ideal host city for would-be immigrants. South Asians constructed ethnic, national, class, and racial identities through the university and the city. The University of Houston became the cultural hub and a key site for identity formation.

Tosylates are among the least expensive, but also among the least reactive toward Pd(0) oxidative addition, of aryl sulfonates. Jie Wu of Fudan University has now devised conditions (J. Org. Chem. 2007, 72, 9346) for the Pd-catalyzed coupling of aryl tosylates such as 1 with arene trifluoroborates. Kei Manabe of RIKEN has found (Organic Lett. 2007, 9, 5593) that an ortho OH activates an adjacent Cl for Pd-mediated coupling, allowing the conversion of 4 to 6 . Philippe Uriac and Pierre van de Weghe of the Université de Rennes I have developed (Organic Lett. 2007, 9, 3623) conditions for the catalytic acylation of aryl halides with alkenyl acetates such as 8. Multi-component coupling lends itself well to diversity-oriented synthesis. As illustrated by the combination of 10 with 11 and 12 to give 13 reported (Organic Lett. 2007, 9, 5589) by Michael F. Greaney of the University of Edinburgh, benzynes can do double addition with high regiocontrol. For other recent references to unsymmetrical double additions to arynes, see Angew.Chem. Int. Ed. 2007, 46, 5921; Chem. Commun. 2007, 2405; and J. Am. Chem. Soc. 2006, 128, 14042. C-H functionalization of arenes is of increasing importance. John F. Hartwig of the University of Illinois has described (Organic Lett. 2007, 9, 757; 761) improved conditions for Ir-catalyzed meta borylation, and conditions for further coupling of the initial borate 16 to give amines such as 17. Lei Liu and Qing-Xiang Guo of the University of Science and Technology, Hefei have found (Tetrahedron Lett. 2007, 48, 5449) that oxygen can be used as the stoichiometric oxidant in the Pd-catalyzed functionalization of H’s ortho to anilides. Two other research groups (J. Am. Chem. Soc. 2007, 129, 6066; Angew. Chem. Int. Ed. 2007, 46, 5554; J. Org. Chem. 2007, 72, 7720) reported advances in this area. In a close competition, Jin-Quan Yu, now at Scripps/La Jolla (J. Am. Chem. Soc. 2007, 129, 3510) and Olafs Daugulis of the University of Houston (J. Am. Chem. Soc. 2007, 129, 9879) both reported that a carboxyl group can activate an ortho H for direct functionalization.

Alessandro Palmieri of the University of Camerino developed (Synlett 2010, 2468) the condensation of a nitro acrylate 1 with a 1,3-dicarbonyl partner 2 to give the furan 3. Chaozhong Li of the Shanghai Institute of Organic Chemistry showed (Tetrahedron Lett. 2010, 51, 3678) that an alkenyl halide 4 could be cyclized to the furan 5. Ayhan S. Demir of Middle East Technical University established (Chem. Commun. 2010, 46, 8032) that a Au catalyst could catalyze the addition of an amine 7 to a cyanoester 6 to give the pyrrole 8 . Bruce A. Arndtsen of McGill University effected (Org. Lett. 2010, 12, 4916) the net three-component coupling of an imine 9, an acid chloride 10, and an alkyne 11 to deliver the pyrrole 12. Bernard Delpech of CNRS Gif-sur-Yvette prepared (Org. Lett. 2010, 12, 4760) the pyridine 15 by combining the diene 13 with the incipient carbocation 14. Max Malacria, Vincent Gandon, and Corinne Aubert of UPMC Paris optimized (Synlett 2010, 2314) the internal Co-mediated cyclization of a nitrile alkyne 5 to the tetrasubstituted pyridine 17. Yoshiaki Nakao of Kyoto University and Tamejiro Hiyama, now at Chuo University, effected (J. Am. Chem. Soc. 2010, 132, 13666) selective substitution of a preformed pyridine 18 at the C-4 position by coupling with an alkene 19. We showed (J. Org. Chem. 2010, 75, 5737) that the anion from deprotonation of a pyridine 21 could be added in a conjugate sense to 22 to give 23. Other particularly useful strategies for further substitution of preformed pyridines have been described by Olafs Daugulis of the University of Houston (Org. Lett. 2010, 12, 4277), by Phil S. Baran of Scripps/La Jolla (J. Am. Chem. Soc. 2010, 132, 13194), and by Robert G. Bergmann of the University of California, Berkeley, and Jonathan A. Ellman of Yale University (J. Org. Chem. 2010, 75, 7863). K. C. Majumdar of the University of Kalyani developed (Tetrahedron Lett. 2010, 51, 3807) the oxidative Pd-catalyzed cylization of 24 to the indole 25. Nan Zheng of the University of Arkansas showed (Org. Lett. 2010, 12, 3736) that Fe could be used to catalyze the rearrangement of the azirine 26 to the indole 27.

In 1972, Lelek introduced the notion of Class (W) in his seminar at the University of Houston [see below for definitions of concepts mentioned here]. Since then there has been much interest in classifying and characterizing continua in Class (W). For example, Cook has a result [5, Theorem 4] which implies that any hereditarily indecomposible continuum is in Class (W) Read [21, Theorem 4] showed that all chainable continua are in Class (W), and Feuerbacher proved the following result:(1.1) THEOREM [7, Theorem 7]. A non-chainable circle-like continuum is in Class (W) if and only if it is not weakly chainableIn [14, 4.2 and section 6], a covering property (denoted here and in [18] by CP) was defined and studied primarily for the purpose of proving that indecomposability is a Whitney property for the class of chainable continua [14, 4.3].

Traditionally, mechanical engineering capstone courses focused on teaching students the application of fundamental engineering theory to complex mechanical designs. Recently, there has been a transition towards experiential learning initiatives, such as prototyping, in engineering design. This paper looks at the relationship between the mechanical engineering design capstone course and a course in product design and development, which provides students with the opportunity to build prototypes of their designs, at the University of Ottawa. The importance of the traditional capstone course is considered and the implications of implementing these designs are examined. Many capstone design projects would require extensive work so that they could be implemented. A large hurdle appears to exist between analytical design and design implementation, and the term time constraints limit the complexity of designs intended for prototyping. In fact, students require many design iterations before they can build full-scale functional prototypes of their design. Therefore, we have observed that simple products work best for teaching design implementation.

At the University Colorado Denver, a manufacturing process design course was specifically created to raise the level of the as constructed senior design projects in the department. The manufacturing process design course creates a feed forward loop into the senior design course, while the senior design course generates a feedback loop into the process design course. Every student and student project has the opportunity to utilize CNC mills and lathes where appropriate. Specific emphasis is placed upon the interfaces from solid models to CAM models and subsequently the interface from CAM models to the machine tool. Often the construction of many senior design projects approaches the level of blacksmithing due to time constraints and lack of fabrication background. Obviously, most engineering students have neither the time nor the ability to become expert fabricators. However, the wide incorporation of CNC machining in the program allows, an opportunity to not only raise the quality of their prototypes, but also to immerse in the hands on experience of living with the ramifications of their own design decisions in manufacturing. Additionally, some of the art of fabrication is turned into the science of fabrication. The focus of this paper will be primarily on examining the effect of formal incorporation of the manufacturing process in the capstone design course.
