A current Supreme Court case concerning lawyer advertising, In re R.M.J., is analyzed in the context of a discussion of the diverse state regulations governing lawyer advertising and solicitation. The article considers the regulations in terms of their constitutionality, their tendency to impede effective advertising, and the effect they have on the legal profession's provision of information to potential clients about the nature, availability, and cost of legal services. Analysis of the major commercial speech cases, from Virginia State Board of Pharmacy to Central Hudson, indicates that many state rules infringe on attorneys' First Amendment rights. 相似文献

A method is described for obtaining nondiffusing, nonfading fluorogenic zymograms for erythrocyte acid phosphatase variants separated by isoelectric focusing. The synthetic substrate 4-trifluoromethylcoumarin phosphate was impregnated into cellulose diacetate membranes and air-dried overnight. After isoelectric focusing, the substrate overlay membrane was rehydrated in 0.05M citrate buffer, pH 4.0, lightly blotted, and overlayed on the gel. A 5- to 10-min incubation at 37 degrees C produced intensely fluorescing, light-blue bands on the diacetate membrane. Interaction of the trifluoromethyl group on the substrate with hydrophobic regions of the diacetate membrane impeded diffusion, yielding a permanent zymogram. There were no discrepancies in phenotype determinations using this method when compared with the 4-methylumbelliferyl phosphate assay approach. Further, an increased number of conclusive calls were obtained (91.8 versus 79.5% and 54.1 versus 34.9%) with this new assay when compared with the 4-methylumbelliferyl phosphate substrate on known liquid bloods and questioned dried bloodstains, respectively. 相似文献

Principally new, simple and objective method for investigation of human hair density is suggested. Hair identity in relation to a concrete person can be confirmed or excluded by statistical processing of the results obtained. 相似文献

Flowers ofMelandrium album are frequently pollinated byCucullia umbratica L. This heavy moth always lands on the flowers. The process of insertion of the proboscis and the drinking thereafter is
described. From experiments it is concluded that senses for perception of the relative humidity of the air are located on
the antennae. The moth is able to locate flowers by smell only, but visual orientation seems to be more predominant. Legs
and antennae possess contact chemoreceptors, sensitive to sucrose and to chemicals present on the surface ofM. album flowers. The moth responds after contact of the legs with petal lobes ofM. album by extension of the proboscis. Inserting behaviour follows only after contact of the proboscis tip with the ligula. The moth
appears to be a specialised flower visitor.
Resume Les fleurs deMelandrium album sont polinisées parCucullia umbratica qui butine ces fleurs après s'y être posé. Les expériences rapportées ici témoignent que des organes sensoriels aptes à percevoir l'humidité de l'air sont localisés sur les antennes. Le papillon peut localiser les fleurs par simple odeur mais l'orientation visuelle semble prédominante. Les pattes et les antennes possèdent des chemorécepteurs de contact, sensibles au sucrose et aux composés chimiques associés aux fleurs deM. album. Le papillon, après contact de ses pattes avec les pétales de cette fleur manifeste une extension de son proboscis et ce n'est qu'après contact de ce dernier avec la ligula, que se réalise l'insertion dans la corolle. Ce papillon semble être spécialisé comme visiteur de fleurs.相似文献

Ideographic representations (schematic drawings) are useful for analyzing and communicating complex ideas. They constitute simplified versions of the way multiple and diverse elements, concepts, and variables interact according to each author's conceptions, knowledge, and experience of planned change and change phenomena. Such representations depict a sense of order under a particular model configuration or system notion, involving contexts where action takes place and events occur. This paper is based on the commonality analysis of 46 models related to technology transfer. Within the framework of previously published research, complementary findings are presented here. The discussion is focused on the characteristics of the models' contexts, appealing to some technology transfer aspects widely omitted or neglected. It is suggested that the understanding of intervention contextual domains is important to formulate and implement better technology transfer models. 相似文献
