Simultaneous quantification of Lamivudine and Zidovudine in tablets by HPTLC method was developed and validated. The chromatograms were developed using a mobile phase of toluene:ethyl acetate:methanol (4:4:2, v/v/v) on pre-coated plate of silica gel GF aluminum TLC plate and quantified by densitometric absorbance mode at 276 nm. The Rf values were 0.41±0.03 and 0.60±0.04 for Lamivudine and Zido...

A collaborative experimental effort was initiated at a workshop at the 1988 Gaseous Electronics Conference ~GEC! to start a program to understand the fundamental physics of processing plasmas, as well as give researchers a baseline experiment to develop plasma diagnostics to be used on manufacturing plasma systems. The design was based on the use of 4 in. diameter, aluminum electrodes in a para...

Permanently attached, distributed sparse arrays of piezoelectric transducers have been proposed as a cost-effective solution for rapid interrogation of large, plate-like structures for structural health monitoring. Many proposed methods using these arrays rely on guided wave imaging techniques to interpret and graphically display information for damage detection and localization. Guided wave im...

The cyclic-tension fatigue in a rolled thin-plate of aluminum alloy Al–4Cu–1Mg was evaluated nondestructively using a horizontally polarized shear wave (SH) transmission method under optimized measuring and analyzing conditions. The propagation time of the SH waves, which contained elements of reflected waves, had three distinct stages, the first, middle and final ones, during the fatigue proce...

This case report describes a simple method for identifying the citizenship of a denture wearer by marking the telephone country code number inside the denture base. A wax pattern for the denture framework was prepared on the refractory cast. A piece of embossing tape, containing the country code (81, Japan), Japanese prefectural code, and abbreviation of the dental clinic where the denture was ...

OBJECT This investigation was undertaken to study the effect of aluminum on neurobehavioral, electrophysiological, structural, and biochemical changes in rats following spinal cord injury (SCI). METHODS Adult male Sprague-Dawley rats classified into different groups were given aluminum sulfate-dosed drinking water in the concentrations of 0%, 0.25%, 0.5% and 1%, respectively. After 30 days of...

In this study, the structural performance of joint construction method using aluminum sprayed plate in concrete was evaluated, and corrosion characteristics film mortar also evaluated. The rate high early stage after placing, but it decreased with passage embedding period. This due to products deposited on surface aluminum, which presumably suppression especially anodic reactions. evaluation, w...

A solar still is a viable option when the demand of potable water does not exceed more than 3 litres. Enhancement in distillate output from the solar still is a main goal of many researchers all over the world. In this research, the effect of copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under the same climate ...

Aluminum-coated plates, containing a uranium silicide (U3Si2) meat dispersed in an aluminum matrix, are commonly used the fuel elements of Material Testing Reactors (MTRs). These typically comprised narrow channels formed by parallel flat which allow coolant flow to remove heat fission reactions. It is important mention that thickness plates much smaller than their width and height. The high ra...

Adhesive bonding of metal sheets presents many practical advantages when compared to other joining methods, but its application for critical components is limited by the absence of reliable nondestructive methods that can assure the bond strength of the joint. In this paper, a method based on shock waves produced by pulsed lasers is applied to the evaluation of adhesive bond strength of two alu...
