    Spatial and seasonal variability of chlorophyll-a, total suspended matter, and colored dissolved organic matter in the Sundarban mangrove forest using earth observation and field data Mosa. Tania Alim Shampa, Md. Kawser Ahmed, K. M. Azam Chowdhury, Md. Ashraful Islam, Mahmudul Hasan, Muhammad Shahinur Rahman, Md. Saiful Islam

    出版 2024-10-01
    “...To examine the current status of the aquatic ecosystem, this study aimed to evaluate the spatial and seasonal fluctuation of three principal water quality attributes namely Chlorophyll-a (Chl-a), Total Suspended Matter (TSM), and Colored Dissolved Organic Matter (CDOM) in the complex tidal river systems of the Sundarban mangroves forest using earth observation and in-situ data. A set of two bio-optical algorithms, Ocean color-2 (OC-2) and Ocean color-3 (OC-3), were applied to measure Chl-a concentration, Green/NIR and the Red/NIR band ratio algorithms were used for TSM and the Case-2 Regional Coast Color (C2RCC) processor in the SNAP software was applied to obtain CDOM concentration in study area. ...”

    The HD 93963 A transiting system: A 1.04 d super-Earth and a 3.65 d sub-Neptune discovered by TESS and CHEOPS Seager, Sara

    出版 2023
    “...The inner object, HD 93963 A b, is a validated 1.04 d ultra-short period (USP) transiting super-Earth that we discovered in the TESS light curve and that was not listed as a TOI, owing to the low significance of its signal (TESS signal-to-noise ratio ≈6.7, TESS +CHEOPS combined transit depth Db = 141.5 +8.5 −8.3 ppm). ...”

    A Study on Interaction of Cd(II) and Diatomaceous Earth in Adsorption Process = Kajian Interaksi Cd(II) dengan Adsorben Tanah Diatomit Pada Proses Adsorpsi. Perpustakaan UGM, i-lib

    出版 2004
    “...In this research, interaction occurring in adsorption process between Cd(II) and active site of diatomaceous earth has been studied. The study was carried out by evaluating Cd(II) adsorption on diatomaceous earth at various pHs, either for the earths without treatment, those after being heated or those treated with sulfuric acid and hydrogen chloride. ...”

    The present-day decadal solar cycle modulation of Earth’s radiative forcing via charged H 2 SO 4 /H 2 O aerosol nucleation Kazil, J, Zhang, K, Stier, P, Feichter, J, Lohmann, U, O Brien, K

    出版 2012
    “...A limited relevance of this variation for the Earth's atmosphere and climate can be inferred, given that Earth's radiative forcing changes by-0.24 W m -2 from solar maximum to minimum because of a decrease in total solar irradiance. © 2012 by the American Geophysical Union....”

    Thermodynamics of rare earth element partitioning between clinopyroxene and melt in the system CaO - MgO - Al2O3 - SiO2 Blundy, J, Wood, B, Davies, A

    出版 1996
    “...We use the experimental data of Gaetani and Grove (1995) on rare earth element (REE) partitioning between clinopyroxene and melt in the system CaO-MgO-Al2O3-SiO2 to constrain the energetics of the coupled substitution REEAl[CaSi]-1. ...”

    Assessment of pozzolanic reactivity for calcined spent bleaching earth ash (SBEA) using strength activity index (SAI), frattini test and x-ray diffraction (XRD) Syaza Syazvina Anwar

    出版 2022
    “...As the application of concrete in this industry had been widely known and applied, the replacement of cement content is needed as cement had been contributed to the higher amount of releasing gas carbon dioxide (CO2) to the atmosphere. As Spent Bleaching Earth is one of the solid wastes that need to be reduced, the recycle product of SBE which is Spent Bleaching Earth Ash (SBEA) can be the solution. ...”

    Evaluation of 5G and fixed-satellite service earth station (FSS-ES) downlink interference based on artificial neural network learning models (ANN-LMS) Al-Jumaily, Abdulmajeed, Sali, Aduwati, Jiménez, Víctor P. Gil, Lagunas, Eva, Natrah, Fatin Mohd Ikhsan, Fontán, Fernando Pérez, Hussein,, Yaseein Soubhi, Singh, Mandeep Jit, Samat, Fazdliana, Aljumaily, Harith, Al-Jumeily, Dhiya

    出版 2023
    “...Therefore, the minimisation of the interference of 5G with other signals already deployed for other services, such as fixed-satellite service Earth stations (FSS-Ess), is urgently needed. The novelty of this paper is that it addresses issues using measurements from 5G base stations (5G-BS) and FSS-ES, simulation analysis, and prediction modelling based on artificial neural network learning models (ANN-LMs). ...”
