Estimation of changes in the Dead Sea surface water area through multiple water indices and geospatial techniques

by

Majed Mahmoud Ibrahim et al. View all

Water Resources Management

The study calculated the changes in the Dead Sea surface area from 1984 to 2019. The satellite images of 1985, 1990, 2000, 2010, and 2019 were classified by applying four different methods to estimate the changes in the Dead Sea surface water area. The methods included normalized difference water...

Detoxification of As(III) in Aqueous Media by Using Photo-Fenton Method

by

Endang Tri Wahyuni et al. View all

Water and Wastewater Treatment

In this paper, photo-Fenton method has been systematically examined to oxidize the toxic and mobile As(III) in the solution by •OH radicals resulted from the reactions between Fe2+ and H2O2 under UV light, to form the less toxic and insoluble As(V). The effects of various experimental parameters...

Deep neural networks for climate relation extraction

by

Jian Zheng et al. View all

Climate change mitigation and adaptation

Climate data composes of time series and space series with unknown. These unknown series contains complex co-variation relations of climate data. The extraction of these relations is essential for further revealing the complex representations between time series and space series in climate data. As...

Purification of Biogas From Tofu Waste using Zeolite and Activated Carbon (AC) as Adsorbent

by

Mochamad Arief Budihardjo et al. View all

Biowaste

Substitution of fossil fuel into alternative energy sources, such as biogas, needs to be applied to prevent various problems in the environment. Biogas purification can be an alternative technology to improve the quality of biogas, which increases the heat value by reducing CO2. Purification can be...
