“…Abundant Ca emission lines were observed, including Ca I emission lines at 422.5,429.8,445.4,526.4,558.8,615.6,645.1,714.8,and 720.2 nm;Ca II emission lines at 315.7,317.7,373.5,393.0,396.5,732.3,854.2,and 866.2 nm; and Ca III emission lines at 642.5 and 648.3 nm (Ahmed, Umar, Ahmed, & Baig, 2017;Juvé, Portelli, Boueri, Baudelet, & Yu, 2008;Velioglu, Sezer, Bilge, Baytur, & Boyaci, 2018;Yaroshchyk, Morrison, Body, & Chadwick, 2005). Several signals at 279.3 and 280.0 nm were attributed to Mg II emission lines and those at 382.9 and 383.5 nm represented Mg I emission lines (Abdel-Salam, Al Sharnoubi, & Harith, 2013;Li, Liu, Chen, & Li, 2008;Mansoori et al, 2011;Rai, Zhang, Yueh, Singh, & Weisberg, 2001;Yaroshchyk et al, 2005;Zheng et al, 2008). An Al I emission line was observed at 309.2 nm (Mansoori et al, 2011;Yaroshchyk et al, 2005).…”

Laser‐induced breakdown spectroscopy (LIBS) is an emerging multi‐elemental analytical technique offering fast and simultaneous quantification of soil properties with minimal sample preparation and effective cost. Due to soil heterogeneity, spectral variation however limits the quantitative robustness. In this study, 348 soil samples were collected and prepared for acquisition of LIBS spectra. Influences of shot layer and number on LIBS quality were evaluated by spectral intensity and relative standard deviation (RSD). Effects of shot layer and number and five normalization procedures on LIBS ability to measure soil organic matter (SOM), total nitrogen (TN), and total soluble salt content (TSC), were evaluated using partial least squares regression (PLSR). Increasing shot number reduced LIBS spectral variance, thereby improving the quantitative accuracy of selected soil properties. Deep shot layers (4th or 5th shot layers) reduced the intensities of soil spectra and thereby decreased the quantitative accuracy for TSC. However, deep shot layers improved the SOM and TN prediction performances. Among the normalization approaches, the method based on the correction of Si line (DS) showed superior performance for improving quantitation of SOM and TN. The arithmetic average method (AA) was best for TSC prediction. Optimization of shot layer, number and normalization procedures of LIBS spectra resulted in fair prediction of SOM (residual prediction deviation of validation set, RPDV = 1.608), good prediction of TN (RPDV = 1.836), and very good quantitative analysis of TSC (RPDV = 2.456). Therefore, our findings illustrate very good potential for improving the quantitative accuracy of the LIBS soil spectra.

Laser-induced Breakdown Spectroscopy (LIBS) was used for the quantitative study of Shilajit samples using first harmonic (1064 nm) of a Q-Switched Nd:YAG laser by an appropriate detection system. The samples were chosen from the northern Himalayan mountainous range at locations namely Skardu, Gilgit, Chilas, Chitral, and Muzaffarabad. The relative concentrations of detected species were measured via integrated intensity of the strongest line of an element and via Calibration-Free CF-LIBS approach. Our findings recommend the altitudinal variations in Physico-chemical properties of Shilajit. Different functional groups were identified using Fourier Transform infrared (FTIR)-Spectroscopy. The results of LIBS were compared to results of Inductively Coupled Plasma/Optical Emission Spectroscopy (ICP/OES) with fine harmony.

<span>La leche materna es el único alimento que le provee al lactante la cantidad y calidad exacta de nutrientes, que requiere para su desarrollo, como carbohidratos, grasas, proteínas e inclusive inmunidad y biomarcadores. Por lo tanto, es fundamental que tanto odontólogos, como el personal del área de salud, comprendan las generalidades de la lactancia, su importancia y la correcta farmacoterapia de la mujer en este periodo; debido a que se pueden utilizar analgésicos como el acetaminofén, diclofenaco e ibuprofeno, los cuales se consideran compatibles con la lactancia y de igual forma los antibióticos de uso frecuente en odontología como las penicilinas y las cefalosporinas. De tal manera que se le pueda ofrecer una atención adecuada y oportuna sin perjudicar la salud de la madre y su hijo.</span>
