The first application of the violet diode laser for laser induced fluorescence (LIF) detection in capillary electrophoresis is reported. Operating at 405 nm with an output power of 5 mW, this laser offers many advantages over conventional red diode lasers operating at 635 nm. We demonstrate the suitability of the violet diode laser for LIF detection by detecting amino acids labeled with naphtha...

background and objectives: studies have documented the morhplogical, neurochemical and functional difference between the dorsal and ventral zones of hippocampus. the aim of this study was to assess the effects of chronic diabetes mellitus type1 on ventral and dorsal zones of hippocampus. methods: experimental diabetes was induced by stereptozotocin at a dose of 60 mg/kg. at the end of 8 weeks ...

Laser equipment is capable of performing ablation and incision while providing hemostasis, and is widely used in intraoral surgery where bleeding can often occur(1). One of the oldest types of laser equipment is CO2 laser. The wavelength of CO2 laser (10.6 μm) is strongly absorbed by water, which means that CO2 laser is suitable for efficient ablation and incision of soft tissues that contain l...

In the preparation of the material and the interpretation of the results, I have had the cooperation of Dr. Mary B. Stark of the Flower Hospital Staff and the assistance of Miss A. K. Marshall of the Bell Telephone Laboratories. The photographs which accompany this paper are sufficiently described in the titles and need not be specifically dealt with here. 1 Lucas, "An Introduction to Ultra-Vio...

Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

Rare-earth doped low phonon glasses are attractive media for unconverted, short wavelength fiber lasers. Fluorozirconate glass (ZBLAN) is one of the most popular representatives of this type of materials. Lasing in the visible part of spectrum has been reported in various upconversion pumped RE doped ZBLAN systems [1-2], but till now generation in the ultra-violet (UV) has only been observed in...

The distal photoreceptors in the tiered retina of Papilio exhibit different spectral sensitivities. There are at least two types of short-wavelength sensitive receptors: an ultraviolet receptor with a normal spectral shape and a violet receptor with a very narrow spectral bandwidth. Furthermore, a blue receptor, a double-peaked green receptor and a single-peaked green receptor exist. The violet...

The results of a study and application of leucocrystal violet for the determination of antimony in parts per million levels is described here. The proposed method is based on the reaction of antimony(III) with acidified potassium iodate to liberate iodine. The liberated iodine selectively oxidizes leucocrystal violet to crystal violet dye. The formed dye shows maximum absorbance at 590 nm. The ...

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...
