Abstractqualifying_street_children_with_music.pdf

This study aims to identify some models and musical projects for qualifying of street children. The researcher followed the descriptive approach (content analysis). The results of the research indicated the effectiveness of experiments, models and musical projects implemented on street children, especially with the application of classical music. The extent to which these experiments affect on reduce crime, raise their morale and change their behavior. Which can be eliminated on the phenomena of intolerance and violence and the evaluation of their morals, and this has already proved the results of previous studies contained in the research.

Aslam Farooq, W., W. Tawfik, F. N. Al-Mutairi, and Z. A. Alahmed, "Qualitative analysis and plasma characteristics of soil from a desert area using LIBS technique", Journal of the Optical Society of Korea, vol. 17, no. 6: Optical Society of Korea, pp. 548-558, 2013. AbstractWebsite

In this work, laser induced breakdown spectroscopy (LIBS) is used to investigate soil samples collected from different desert areas of Riyadh city in Saudi Arabia. Both qualitative analysis and plasma parameters are studied via the observed LIBS spectra. These experiments have been done using a Spectrolaser-7000 system with 50 mJ fundamental wavelength of Nd:YAG laser and detection delay time of 1 microsecond. Many spectral lines are highly resolved for many elements like Al, Fe, Mg, Si, Mn, Na, Ca and K. The electron temperatures Te and electron densities Ne, for the constituent of generated LIBS plasma, are determined for all the collected samples. It is found that both Te and Ne vary from one desert area to other. This variation is due to the change of the elemental concentration in different desert areas that affects the sample’s matrices. Time dependent measurements have also been performed on the soil samples. While the signal-to-base ratio (SBR) reached its optimal value at 1 microsecond, the plasma parameters Ne and Te reach values of 4×1017 cm-3 and 9235 K, respectively, at 2.5 microsecond. The later indicate that the plasma cooling processes are slow in comparison to the previously observed results for metallic samples. The observed results show also that in the future it is possible to enhance the exploitation of LIBS in the remote on-line environmental monitoring application, by following up only the values of Ne and Te for one element of the soil desert sample using an optical fiber probe. © 2013, Optical Society of Korea.

Abstract

We have presented Analysis of UV irradiated dental nanocomposites restorative materials using laser-induced breakdown spectroscopy (LIBS). Samples of the materials are irradiated with UV light using 3M ESPE Elipar FreeLight2 Source. LIBS spectra of the samples are recorded using fundamental beam from Q-Switched Nd: YAG laser in conjunction with MS257 Spectrograph (Oriel instrument) equipped with Andor iStar ICCD camera. The emission spectra of these samples have been recorded as a function of laser irradiance. Traces of Titanium, Silicon, Aluminum, Strontium, Zirconium, Sodium and Calcium are detected in these samples. The elemental composition is found to be quite similar but the relative abundance of Zr and Si is higher in more UV exposed material. The samples have also been analyzed with SEM EDS for comparison. © 2014 IEEE.
