Cohen, Elaine | Feature-based process planning for CNC machining | Today CNC machining is used successfully to provide program-driven medium lot size manufacturing. The range of applicability of CNC machining should be greater: For small lot sizes such as prototyping or custom products, these machines should provide quick turnaround and flexible production schedul... | CNC machining | 1998 |

Morse, Michael David | First spectroscopic investigation of the 4 d transition metal monocarbide MoC | The first optical spectroscopic investigation of MoC has revealed a complicated vibronic spectrum consisting of about 35 bands between 17 700 and 24 000 cm-1. Analysis has shown the ground state to be the ?=0+ spin?orbit component of a 3?- state that derives from a 10?211?25rr42d 2 configuration. Th... | 1998 | |

Hughes, Kelly T. | Flagellar anti-σ factor FlgM actively dissociates Salmonella typhimurium σ28 RNA polymerase holoenzyme | The anti-σ factor FlgM of Salmonella typhimurium inhibits transcription of class 3 flagellar genes through a direct interaction with the flagellar-specific σ factor, σ28. FlgM is believed to prevent RNA polymerase (RNAP) holoenzyme formation by sequestering free σ28. We have analyzed FlgM-media... | sigma-factors; transcription; FlgM; Flagellum | 1998 |

Hibler, Michael J. | The flask security architecture: system support for diverse security policies | Operating systems must be flexible in their support for security policies, i.e., the operating system must provide sufficient mechanisms for supporting the wide variety of real-world security policies. Systems claiming to provide this support have failed to do so in two ways: they either fail to pro... | Flask; Security architecture | 1998 |

White, Paul H. | Flexible correction processes in social judgment: implications for persuasion | Two experiments were conducted to examine correction for perceived bias in persuasion situations. Study 1 showed that, although a manipulation of source likability had an impact on attitudes when no instruction to remove bias was present, when people were asked to remove any bias from their judgmen... | Manipulation; Likability; Biasing | 1998 |

Capecchi, Mario R. | Gene targeting: an historical perspective | Our entry into what was going to become the field of gene targeting began in 1977. I was experimenting with the use of extremely small glass needles to inject DNA directly into the nuclei of living cells. The needles were controlled by hydraulically driven micro-manipulators and were directed into n... | Gene targeting -- History; Homologous recombination | 1998 |

Chapman, David S. | Geothermics and climate change: 1. Analysis of borehole temperatures with emphasis on resolving power | Temperature-depth data from six boreholes in western Utah and nine boreholes in southeastern Utah are reanalyzed for evidence of ground surface temperature (GST) histories. We invert the temperature-depth data using the functional space inverse algorithm of Shen and Beck [1991, 1992] which we prefer... | Surface air temperature; Ground surface temperature; Borehole temperatures; Geothermal observations; Geothermics | 1998 |

Chapman, David S. | Geothermics and climate change: 2. Joint analysis of borehole temperature and meteorological data | Long-period ground surface temperature variations contained in bore hole temperature-depth profiles form a complementary climate change record to high-frequency, but noisy surface air temperature (SAT) records at weather stations. We illustrate the benefits of jointly analyzing geothermal and meteo... | Surface air temperature; Ground surface temperature; Borehole temperatures; Geothermal observations; Heat transfer | 1998 |

Chapman, David S. | Global warming - just hot air? | We know from weather station records that Earth's surface temperature has increased on average by 0.6 degrees C in the last 100 years. The 1990s have been the warmest decade on record. Over the same period, global sea level has increased by 10-20 cm. We know also that planet Earth has an atmosphere ... | Greenhouse Effect; Climate change | 1998 |
