The formula for crystal violet given in Conn's book (1940) implies that quantitative measurement of the dye adsorbed by bacterial cells should be possible by a suitable micro-Kjeldahl procedure. At the present time there is no satisfactory method for estimating the degree of gram positivity although the need for such a procedure is recognized and is discussed by Bartholomew and Mittwer (1952). ...

We establish the ultraviolet finiteness of various classes of noncommutative gauge theories.

Phosphorus has diverse chemical bonds, and even in its two-dimensional form, there are three stable allotropes: black phosphorene (Black-P), blue (Blue-P), violet (Violet-P). Due to the complexity of these structures, no efficient accurate classical interatomic potential been developed for them. In this paper, we develop an machine-learned neuroevolution model allotropes apply it study thermal ...

BACKGROUND Low power violet laser diodes (VLDs) have been evaluated as potential replacements for water-cooled argon-ion and krypton-ion ultraviolet and violet lasers for DNA content analysis using the Hoechst dyes and 4,6-diamidino-2-phenylindole (Shapiro HMN, Perlmutter NG: Cytometry 44:133-136, 2001). In this study, we used a VLD to excite a variety of violet-excited fluorescent molecules im...

Burkholderia cepacia complex (BCC) represent a group of opportunistic organisms that cause wide variety infections including the nosocomial. The organism is found to sepsis and also reported blood stream in malignancy. Here, we present case series five patients with which an unsual violet pigment producing BCC was isolated.
