Silverman, Randall H. | First word in lasting impressions | The creaking lever-action of a Columbian letterpress printing damped, handmade paper with cast metal type is an anomaly in the modern age. What now can be achieved within minutes on an offset press requires hours of meticulous setting, locking up, inking, and proofing to print on a Columbian powered... | Columbian letterpress; Clymer; Red Butte Press | 1993 |

Ogburn, Joyce L. | Acquiring minds want to know: [readers' survey] | In preparation for a discussion at the Charleston Conference, I am asking librarians, vendors, publishers, and system vendors who read Against the Grain to answer a survey about how services and products that support information delivery and dissemination are developed and change over time. For exa... | Reader surveys; Libraries; Acquisitions; Vendors | 1993 |

Clayton, Dale H. | Common grackle anting with lime fruit and its effect on ectoparasites | Anting is stereotyped behavior in which birds ex- pose themselves to fluid-secreting ants or other pun- gent substances. During "active" anting a bird crush- es an ant in the bill and rubs it frenetically through its plumage (Rothschild and Clay 1952). During "passive" anting a bird entices ants to ... | Quiscalus quiscala; Columbicola columbae; Anting; Ectoparasites | 1993 |

Coley, Phyllis D.; Kursar, Thomas A. | Colonization of tropical rain forest leaves by epiphylls: effects of site and host plant leaf lifetime | In humid tropical regions, leaves are frequently colonized by epiphylls (Richards 1954, Pocs 1978, 1982). Lichens and liverworts usually dominate, although mosses, algae, and cyanobacteria can also occur (Winkler 1971, Smith 1982). The interactions between epiphylls and host leaves have not been wel... | Tropical forest; Epiphylls; Panama; Hybanthus prunifolius; Light interception | 1993 |

Mathews, V. John | Volterra and general polynomial related filtering | This paper presents a review of polynomial filtering and, in particular, of tlie truncated Volterra filters. Following the introduction of the general properties of such filters, issues such as eficieiit realizations, design, adaptive algoritlims and stability are discussed. | 1993 | |

Miller, Jan D.; Wan, Rong Yu | Research and development activities for the recovery of gold from noncyanide solutions | Although most gold production from primary resources is achieved by cyanidation, many research activities have focused on alternative processes using noncyanide lixiviants. Such research has been prompted by environmental concerns and problems associated with the processing of refractory gold ores. ... | Activated carbon adsorption; Cementation; Solvent extraction; Ion exchange; Reduction-precipitation; Halide solutions; Thiourea solutions; Lixiviants | 1993 |

Morse, Michael David | Photodissociation measurements of bond dissociation energies: Ti?+, V?+, Co?+, and Co?+ | The bond dissociation energies of Ti2+, V+2 , Co+2, and Co: have been measured from the sudden onset of predissociation in the photodissociation spectra of these molecules, yielding values of D?(Ti+2)=2.435+0.002 eV, D?(V+2)=3.140?0.002 eV, D?(Co+2)=2.7651?0.001 eV, and D?(Co+3)=2.086?0.002 eV.

Francis, Leslie | Law and Philosophy;: from skepticism to value theory | To write about Philosophy; and law is both odd and daunting. It is odd because the topic seems to presuppose that the two fields are separate and that Philosophy; may be unfamiliar to legal practice and legal practitioners. Yet, recognized or not, Philosophy; is part of the ordinary life of law sch... | 1993 | |

Morse, Michael David | Spectroscopic analysis of jet-cooled AICu | Diatomic AlCu has been interrogated using resonant two-photon ionization spectroscopy in a supersonic expansion of helium. The ground state is shown to be X l?+, deriving from the 3&3dgd configuration, in agreement with theoretical predictions. The closed-shell nature of this molecule results in a l... | 1993 | |

Davidson, Diane W. | Ant-plant symbioses in Africa and the neotropics : history, biogeography and diversity | Symbiotic ant-plant relationships afford an excellent opportunity to analyze the effects of both historical and ecological factors on the evolution of mutualisms. Occurring in tropical forests throughout the world, all myrmecophytic plants provide food and permanent housing to ants; the ants, in t... | Ant-plant symbiosis; Africa; Neotropics; Myrmecophytes; Plant-ants | 1993 |
