Clinical Toxicology, 1975
Scott's three-solution procedure was examined and should be considered the method of choice for testing pure compounds suspected to be cocaine. Because of false positives for cocaine encountered with mixtures of drugs such as lidocaine and phencyclidine, Scott's procedure should be confirmed using Kodak's Field Kit for alkaloids, or a similar kit.

Current Protocols in Immunology, 1995
AbstractProper identification of animals is crucial in research, whether the animals are being used as experimental subjects, for breeding purposes, or as a source for tissues, cells, or fluids. This unit provides specific protocols for the ear punch (notch) and ear tag methods for mouse, rat and hamster; tattoos for mouse, rat and rabbit; and the ...

Identification and Lack of Identification
Econometrica, 1983The paper discusses cases where an econometric model linear in the variables is identified, but where the estimators are not asymptotically normally distributed. Maximum likelihood estimators and instrumental variable estimators are considered in some detail and the results are illustrated by means of a Monte Carlo simulation of a particularly simple ...

Natural Language Semantics, 2012
This paper gives a novel analysis of identificational sentences such as This is Mary, That is a beautiful woman, or This looks like Mary based on the notion of a trope. On that analysis, bare demonstratives in the subject position of an identificational sentence involve reference to a trope as the direct object of perception and the sentence itself ...

Conserved Segment Identification
Journal of Computational Biology, 1997The quantitative study of evolution based on comparative map data is dependent on the definition and identification of conserved segments remaining after interchromosomal exchanges such as reciprocal translocation. Because of experimental error and, more important, extensive local intrachromosomal rearrangement, it is difficult to reconstruct the ...

Annals of Allergy, Asthma & Immunology, 1998
The purpose of this review is to introduce the reader to a systematic approach to categorizing pollen types. This will enable the reader to recognize pollen characteristics of the most common botanical sources and determine the relevant contributors to the local aeroallergen burden.Allergenic plant and pollen atlases for pollen characteristics, allergy

Annual Review in Automatic Programming, 1995
Abstract We present a conceptual characterization of the various ways of addressing the problem of identification for control. This leads us to distinguish between a dual control approach, an optimal experiment design approach and a robust control approach.

Aggregation and Identification
International Economic Review, 1976THE PURPOSE OF THIS PAPER is to develop the theory of aggregation in a relatively simple and general manner. The theory encompasses linear and nonlinear models, with the results for linear models emerging as special cases of a more general treatment. It was recognized at an early stage of the investigation of aggregation problems that the analysis must
