Organometallic Compounds
[ send me this paper ]
A 5 page overview of the history of and uses for this broad range of highly reactive compounds so often used as catalysts for many of the processes involved in products ranging in function from containing milk to operating supercomputers. The paper discusses carbonyl cations and anions, hydroformylation and polyalkene polymerization. The entire area of organometallic compounds has been important for decades, but it has been only recently that new discoveries and realization of new uses for old processes has led to increasing benefits so numerous they appear to be limited only by our ability to find them. Bibliography lists 6 sources.

Planet Hunters May Rival Indiana Jones.
[ send me this paper ]
(5 pp) "Or it might have formed from a large burp
of matter from its host star, or maybe a passing
star just left a chunk of itself behind at some time in the past, "Marcy said. "It may even have moons around it, but I just don't know what to call it." Sounds like conversation from a discarded sci-fi novel, doesn't it? How about that is real conversation from January of this year (2001). Geoffrey Marcy of the University of California, at Berkeley, calls himself a "planet hunter." He and his team have located "something,"123 light-years from Earth, is indeed a planet, it would be the largest ever detected. This guy is so big we don't know what to call it," Marcy said.
Bibliography lists 3 sources and 2 visuals of
expoplanets.

Plant Physiology: The Role of Heat and Auxin Regulation
[ send me this paper ]
A 6 page discussion of the role of auxin in plant physiology. Concentrates on the work with Arabidopsis thaliana but ties this research into other plant species and the effects of fire on the physiology of some of these species. Bibliography lists 5 sources.

Plastics Design and Manufacturing
[ send me this paper ]
A 15 page paper discussing gains and persistent
assumptions. Many of the problems attributed to manufacture are not those of the manufacturing process, but rather deficiency in design. Of course products need to be envisioned before they can be produced, but a failing of many manufacturing engineers is that of not approaching their design duties from a variety of perspectives, including manufacturing. This paper describes and analyzes a circuit board assembly line, assesses the
evolution of the manufacturing of three-prong electrical plugs and speculates on the type of
plastic that could be used in manufacturing processes following the path of the processes in
which steel is produced. Bibliography lists 9 sources.
