HIGH ENERGY DOUBLE PEAK PULSE LASER INDUCED PLASMA SPECTROSCOPY FOR METAL CHARACTERIZATION USING A PASSIVELY Q-SWITCHED LASER SOURCE AND CCD DETECTOR

Here, the development and testing of a portable double peak pulse laser induced plasma spectroscopy (DPP-LIPS) based on passively Q-switched Nd:YAG (Neodymium-doped Yttrium Aluminum coleman powermate air tool set Garnet) laser excitation is reported.The latter delivered structured laser pulses at a repetition rate of up to 20 Hz, including two ener

Drought and high-temperature stress are the main abiotic stresses that alone or simultaneously affect the yield and quality of pears worldwide.However, studies on the mechanisms of drought or high-temperature resistance in pears remain elusive.Therefore, the molecular responses of Pyrus betuleafolia, the widely used rootstock in pear production, to

Helicobacter pylori is one of the most common human infections worldwide and it is estimated that more than half of global population is affected.This microorganism induces oxidative stress in gastric mucosa and causes chronic gastritis, duodenal peptic ulcer, gastric cancer, and as reasonably suspected a number of extragastric diseases [1,2].Our r

To discover or delineate mineral deposits and other geological features such as faults and lithological boundaries in their host rocks, seismic methods are preferred for imaging the targets at great depth.One major freetress deep twist crochet hair 14 inch goal for seismic methods is to produce a reliable image of the reflectors underground given t

This work analyzed the 3.5 land surface scheme coupled in the Regional Climate Model RegCM4 (RegCLM), seeking to identify the impact of this coupling in the climatology and in the interannual variability, mainly in the Southeast of Brazil.The climatology analysis showed that the RegCLM, for DJF, is more humid than the set of observations used, over
