The application of Leuco Crystal Violet (LCV) for the enhancement of footwear and fingerprint impression evidence was first utilized in the FBI Laboratory in late 1993, after learning from Mr. John F. Fischer (1) of the formulation of this reagent. Mr. Fischer subsequently made a presentation on this topic at the International Symposium on Footwear and Tire Tread Impression Evidence at the FBI ...

In this paper we describe a storage system called Violet that efficiently marries fine-grained host side data management with capacity optimized backend disk systems. Currently, for efficiency reasons, real-time analytics applications are forced to map their in-memory graph like data structures on to columnar databases or other intermediate disk friendly data structures when they are persisting...

ducing to the medical world the possibilities of treating successfully diseases of the integument by light. It very possibly had not occurred to him how great a field he was opening up when first he directed his attention to concentrating the radiant energy of the sun upon the skin for the purpose of destroying in situ the germs of disease; but undoubtedly he was the pioneer of all that is now ...

Effluent of various industries contain number of inhibitory substances which are continuously added in sea via river and results in water pollution. There is need to degrade the organic content to abate water pollution. In the present study, actinomycetes were isolated on glycerol aspargine agar from marine sample of Calangut beach, Goa. The isolates were tested for their potential to tolerate ...

At the present time there is no satisfactory procedure for estimating the degree of gram positivity although the need for a quantitative method is widely recognized. Recently Kennedy and Barbaro (1953) reported an accurate and reproducible method for determining quantitatively the adsorption of crytl violet by bacteria. In addition, the effect of the species and strain of the organism used, the...

Determination of the absorption spectra of pure preparations of Northrop's crystalline pepsin inactivated by irradiation with ultra-violet light shows that the total absorption in the ultra-violet region of the spectrum increases with the degree of inactivation. This increase is especially marked between 2400 and 2750 A.u. The rate of photoinactivation is shown to be sensitive to changes in pH,...

BACKGROUND Due to controversially discussed results in scientific literature concerning changes of electrical skin impedance before and during acupuncture a new measurement system has been developed. METHODS The prototype measures and analyzes the electrical skin impedance computer-based and simultaneously in 48 channels within a 2.5×3.5 cm matrix. Preliminary measurements in one person were ...

Bio-absorbent palm fiber was applied for removal of cationic violet methyl dye from water solution. For this purpose, a solid phase extraction method combined with the artificial neural network (ANN) was used for preconcentration and determination of removal level of violet methyl dye. This method is influenced by factors such as pH, the contact time, the rotation speed, and the adsorbent dosag...

The effect of oxidative stress exerted by 0.03% crystal violet, 0.3% bile salt, 4.0% NaCl and 8% ethanol on the survival and production of virulence factors among Acinetobacter haemolyticus isolates obtained from wastewater and river water samples was investigated. Though generally there was insignificant lethal effect against all the isolates, crystal violet exerted the highest lethal effect f...
