Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
(
Korean Society of Industrial Engineering Chemistry
, 2014 , Article)
The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ...
Investigating chlorophyll and nitrogen levels of mangroves at Al-Khor, Qatar: an integrated chemical analysis and remote sensing approach. Environmental Monitoring and Assessment
(
Springer Verlag
, 2016 , Article)
Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were ...
Manganese-Loaded Activated Carbon for the Removal of Organosulfur Compounds from High-Sulfur Diesel Fuels
(
WILEY-VCH Verlag
, 2014 , Article)
The adsorptive capacity of activated carbon (AC) is significantly enhanced toward weakly interacting organosulfur compounds (OSC) from sulfur-rich diesel fuel. Sulfur compounds are selectively removed from diesel after ...
Caught basking in the winter sun: Preliminary data on winter thermoregulation in the Ethiopian hedgehog, Paraechinus aethiopicus, in Qatar
(
Academic Press
, 2016 , Article)
Biologists focus on thermoregulation of desert mammals in terms of how they minimize heat gain, and put less effort on how they maximize heat gain during the cooler months. Heat gain may contribute to significant energy ...
Global patterns and predictions of seafloor biomass using random forests
(
Public Library of Science
, 2010 , Article)
A comprehensive seafloor biomass and abundance database has been constructed from 24 oceanographic institutions worldwide within the Census of Marine Life (CoML) field projects. The machine-learning algorithm, Random ...
Chemical composition and evaluation of antioxidant and antimicrobial activities of Tunisian Thymelaea hirsuta with special reference to its mode of action
(
Elsevier B.V.
, 2013 , Article)
In the present study, we evaluated in vitro antimicrobial and antioxidant properties of Thymelaea hirsuta extracts as well as its phytochemical composition. Total phenolic and flavonoid contents were highest in acetone and ...
Co-occurrence of mycotoxins in commercial formula milk and cereal-based baby food on the Qatar market
(
Taylor and Francis Ltd.
, 2018 , Article)
The present study was conducted to explore the occurrence of mycotoxins in commercial baby foods in Doha-Qatar. LCMS/MS- and HPLC-based analysis of baby food (n?=?67) for 12 mycotoxins confirmed the presence of aflatoxin ...
Impact of thinning on carbon storage of dead organic matter across larch and oak stands in South Korea
(
SISEF - Italian Society of Silviculture and Forest Ecology
, 2016 , Article)
Dead organic matter is important in carbon (C) sequestration because it accounts for a significant proportion of forest C storage. As thinning could alter the C storage of dead organic matter, this study aimed to assess ...
Influence of diesel acidification on dibenzothiophene removal: A new desulfurization practice
(
Elsevier
, 2015 , Article)
Commercial diesel is often loaded with organosulphur compounds including hard-to-remove dibenzothiophene DBT and other derivatives. Following uncommon and simple procedure, dibenzothiophene was selectively removed upon ...
