| 101 |  | Miller, Jan D. | Noncyanide leaching of an auriferous pyrite ore from Ecuador | Gold leaching of an auriferous pyrite ore from the Portovelo deposit in Ecuador indicates that noncyanide leaching systems, such as thiocyanate and thiourea, are not as effective as the traditional cyanide system. For example, whereas approximately 95% of the gold can be leached from the ore with cy... | Gold leaching; Refractory ores; Thiocyanate; Thiourea | 2000 |

Michael | Nuclear magnetic resonance solution conformation of α-conotoxin AuIB, an α3ß4 subtype-selective neuronal nicotinic acetylcholine receptor antagonist | The neuronal nicotinic acetylcholine receptors constitute a highly diverse group, with subtypes consisting of pentameric combinations of α and ß subunits. α-Conotoxins are a homologous series of small peptides that antagonize these receptors. We present the three-dimensional solution structure ... | Conotoxins; a-conotoxin AuIB | 2000 |

| 104 |  | Farmer, Colleen G. | Parental care: the key to understanding endothermy and other convergent features in birds and mammals | Birds and mammals share a number of features that are remarkably similar but that have evolved independently. One of these characters, endothermy, has been suggested to have played a cardinal role in avian and mammalian evolution. I hypothesize that it is parental care, rather than endothermy, that ... | Evolution; Metabolism; Convergence | 2000 |

| 112 |  | Zhdanov, Michael S. | Quasi-analytical approximation and series in electromagnetic modeling | The quasi-linear approximation for electromagnetic forward modeling is based on the assumption that the anomalous electrical field within an inhomogeneous domain is linearly proportional to the background (normal) field through an electrical reflectivity tensor ˆλ.

| 114 |  | Truong, Thanh | Reaction class transition state theory: hydrogen abstraction reactions by hydrogen atoms as test cases | We present a new method called Reaction Class Transition State Theory (RC-TST) for estimating thermal rate constants of a large number of reactions in a class. This method is based on the transition state theory framework within the reaction class approach. Thermal rate constants of a given reacti... | Transition state theory; Hydrogen | 2000 |
| 115 |  | Henderson, Thomas C. | Reaction-diffusion processes as a computational paradigm | Turing introduced reaction diffusion systems (RD-systems) as a mechanism which made possible the differentiation of morphological structure. We have shown how these systems can be used to provide an information network for smart sensor systems. However, we propose here that reaction diffusion system... | Reaction diffusion systems; RD-systems; Computational paradigm | 2000 |

| 118 |  | White, Nicholas P. | Review of Nancy Sherman, "Making a Necessity of Virtue | Making a Necessity of Virtue is about the ethics of Aristotle and Kant. "Specifically," according to the first chapter, it "is about the role of emotions and practical reason in each theorist's account of virtue," though with "greater attention to the place of emotions in moral character". This desc... | Virtue; Ethics; Reason; Emotions; Morality | 2000 |
| 119 |  | Riloff, Ellen M. | Rule-based question answering system for reading comprehension tests | We have developed a rule-based system, Quarc, that can read a short story and find the sentence in the story that best answers a given question. Quarc uses heuristic rules that look for lexical and semantic clues in the question and the story. We have tested Quarc on reading comprehension tests typi... | Quarc; Reading comprehension | 2000 |
| 120 |  | Benham, Bryan | Ryle and the para-mechanical | The thesis of this paper is the unconventional claim that Gilbert Ryle is not a logical behaviorist. The popular account of Ryle clearly places his work in The Concept of Mind (1949) in the camp of logical behaviorist.1 The object of this paper, however, will be to illustrate how the conventional in... | Behaviorist; Logical behaviorism | 2000 |

| 122 |  | Werner, Carol M. | Service-learning "rules" that encourage or discourage long-term service: implications for practice and research | We use research and theory on intrinsic motivation to suggest that some service-learning practices may be counter-productive. Although these practices may encourage student involvement in the short-term, they may reduce interest over the long-term. We pose seven questions about service requirements ... | Community; Choice; Opportunities | 2000 |
| 123 |  | Barusch, Amanda | Serving older men: dilemmas and opportunities for geriatric care managers | Geriatric care settings are essentially feminine. Most of the clients (or patients) are women, as are most of the care managers and care providers. Further, these settings are characterized by an "ethic of care," most compatible with a feminine world view. Clearly geriatric care is not specifical... | 2000 | |
