Titanium-doped gallium lanthanum sulfide (Ti:GLS) and gallium lanthanum oxysulfide (Ti:GLSO) glasses have an absorption band at 500–600 nm that cannot be fully resolved because of its proximity to the band edge of the glass. At concentrations 0.5% a shoulder at 980 nm is observed in Ti:GLS but not in Ti:GLSO. The emission spectra of Ti:GLS and Ti:GLSO both peak at 900 nm with lifetimes of 67 an...

cotio3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 - 800°c for 2 hours. the presence of rhombohedra phase of cotio3 in clay matrix was confirmed by xrd, ftir, sem. cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. the spectra results were investigated at 20% (w/w) concentration .the optimum condition ...

The phenomenologically observed property of σ(600) in our recent analyses of various ππscattering and -production processes is reviewed and compared with the prediction of SU(2) linear σ model. Furthermore, a possibility of the scalar σ-nonet (σ(600), κ(900), f0(980) and a0(980)) forming with the pseudoscalar π-nonet a linear representation of SU(3) chiral symmetry is investigated. The origin o...

Abstract. Utilizing date palm waste as an energy source is a potential low-carbon source, especially in areas such the Middle East. This study investigates air gasification performed downdraft gasifier. The aims to analyze impact of various parameter ranges temperature 600-900 ᵒC, flow rate 1.0 4.0 l/min, and particle size <2-6> mm on gas ratios producer gas. H2/CO ratio important which i...

BACKGROUND The hydrophilic bile acid, ursodeoxycholic acid (UDCA), may indirectly protect against colon carcinogenesis by decreasing the overall proportion of the more hydrophobic bile acids, such as deoxycholic acid (DCA), in aqueous phase stool. In the AOM rat model, treatment with UDCA resulted in a significant decrease in adenoma formation and colorectal cancer. It was hypothesized that the...

The implementation of a nationwide lockdown to curb the spread COVID-19 disease has reduced loading anthropogenic aerosols. However, AOD distribution over South Asia during period shows dipole pattern: reduction North Indian and enhancement Myanmar region. This pattern is evident in some datasets (MODIS, MERRA, CALIPSO). MODIS fire counts collocated with CALIPSO smoke aerosols show indicating c...

We introduce a novel video-rate hyperspectral imager with high spatial, temporal and spectral resolutions. Our key hypothesis is that profiles of pixels within each super-pixel tend to be similar. Hence, scene-adaptive spatial sampling scene, guided by its segmented image, capable obtaining high-quality reconstructions. To achieve this, we acquire an RGB image the compute super-pixels, from whi...
