An assay technique, homogeneous enzyme immunoassay, is described for the quantitative determination of morphine derivatives in biological fluids. An enzyme is labeled with morphine. When the enzymelabeled morphine is bound by antimorphine antibodies, the enzyme is rendered inactive. Free morphine competes with enzyme-morphine for antibody binding sites preventing inhibition of enzyme activity. ...

the carabid beetle pterostichus (phonias) strenuus (panzer) is newly recorded from iran. it was collected by hand from ghaleroudkhan forests in the caspian province of guilan. this carabid beetle is widely distributed throughout the palaearctic region including europe, uzbekistan, kazakhstan and russian far east.

Dr. Brent Stewart’s review for the Center for Independent Expertise (CIE) contains helpful comments for SWFSC scientists to use in writing the results of our study on population structure of harbor seals in Alaska for journal publication. Here we respond not to positive points but rather to points that require clarification or, when we disagree, a rebuttal. Dr. Stewart also gives legal advice a...

A new CIE color appearance model (CIECAM02) has been developed. This paper describes the three major drawbacks of the earlier CIECAM97s model, and shows how the new model performs in these color regions. In addition, both models were tested using available data groups. The results are consistent in that CIECAM02 performed as well as, or better than, CIECAM97s in almost all cases, there being a ...

We suggest a framework for predicting color appearance of image data. The image data are converted by a series of standardizing transformations into a simpler stimulus with the same color appearance. By working through these standardizing transformations, we can build color appearance models for images without abandoning—or repeating—much of the work that has gone into defining the visual prope...
