Sorption characteristics of Co which is rather troublesome nuclide from the aspect of low level radioactive waste disposal was studied. By use of ultraviolet-visible spectrophotometer, coexistence of ionic and colloidal cobalts was verified in aqueous solution with pH>7. Column test was carried out with pH=8.75 and it showed that breakthrough curve obtained consists of two types of curves due t...

We present the results of the aerosol measurements carried out over the Aegean Sea during the Photochemical Activity and Solar Ultraviolet Radiation campaign held in Greece during June 1996. Simultaneous observations performed with a lidar and a double-monochromator spectrophotometer allowed us to retrieve the optical depth, the Angström coefficient, and the backscatter-to-extinction ratio. The...

A new reflectometer-spectrophotometer has been designed and constructed using state-of-the-art technology to enhance optical properties of materials measurements over the ultraviolet, visible, and near-infrared (UV-Vis-NIR) wavelength range (200 nm to 2500 nm). The instrument, Spectral Tri-function Automated Reference Reflectometer (STARR), is capable of measuring specular and diffuse reflectan...

Atomic Absorption Based Techniques. Atomic Fluorescence Spectroscopy. Figure 1.3 Schematic diagram showing the before (left) and after (right) the draw the sample into a nebulizer by the Bernoulli Effect where it is converted. Atomic absorption and emission spectroscopy in the ultraviolet and visible A schematic diagram of a UV-Vis spectrophotometer is shown in Figure.11. Preface Inductively co...

Drug counterfeiting has exaggerated dramatically over the past decade causing a significant threat to human health. It must be processed in regard to medicines and the matter isn't restricted to a violation of belongings rights, however clearly involves every kind of poor quality pharmaceutical merchandise, including falsified and substandard medicine. The present paper discuss the review of th...

Fenestration, comprising windows and other openings in a building, influences occupant health well-being while also enhancing energy efficiency through optimized design placement. Selecting glazing materials that block or filter harmful UV radiation is crucial, as having reliable methods to measure their transmission. This research paper, which comprises Part I of II, conducts an exhaustive ana...

The main cause of stunting is due to inadequate food intake according the needs for growth and development children, or insufficient nutrition pregnant women. low nutritional lactating mothers as well children under five years old who are still growing developing generally caused by wrong diet. One efforts prevent from an early age search several sources animal source containing protein, fat ma...
