Acutodesmus obliquus as a benchmark strain for evaluating methane production from microalgae: Influence of different storage and pretreatment methods on biogas yield
( Elsevier , 2015 , Article)Acutodesmus obliquus (SAG 276-1), a microalga with a resistant cell wall, was chosen as a benchmark strain for testing the effect of storage and pretreatment methods on methane yields during anaerobic digestion. A. obliquus ... -
Adaptation of sea turtles to climate warming: Will phenological responses be sufficient to counteract changes in reproductive output?
( John Wiley and Sons Inc , 2024 , Article)Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ... -
The Adsorption Potential of Cr from Water by ZnO Nanoparticles Synthesized by Azolla pinnata
(2022 , Article)Aqueous solutions containing toxic elements (TEs) (such as hexavalent chromium (Cr (VI)) can be toxic to humans even at trace levels. Thus, removing TEs from the aqueous environment is essential for the protection of ... -

Allelopathic effects of Casuarina equisetifolia L. on seed germination of some crop plants and their associated weeds
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Casuarina equisetifolia L. is a widespread tree that has been known for its allelopathic potential causing biological inhibition on plant seed germination. Leaf extract of Casuarina equisetifolia L. was evaluated for its ... -
Alleviation of drought and salt stress in vegetables: crop responses and mitigation strategies
( Springer Science and Business Media B.V. , 2023 , Article)In recent decades, the demand for vegetables has increased significantly due to the blooming global population. Climate change has affected vegetable production by increasing the frequencies and severity of abiotic and ... -
Altering shale permeability by cold shock
( Elsevier , 2024 , Article)The matrix permeability of shale is on the order of nanodarcy (nD), and hydrocarbon recovery from it is economical only after hydraulic fracturing. Another fracturing technique, which is often overlooked, is cryogenic ... -
An integrated approach for produced water treatment using microemulsions modified activated carbon
( Elsevier Ltd , 2019 , Article)In this study, the physical and chemical characterization of produced water was done followed by treatment through sand filtration coupled with activated carbon microemulsion modified activated carbon techniques. The results ... -
ANEUPLOIDY IN THE PEARL OYSTER PINCTADA RADIATA (LEACH, 1814): EVIDENCE FOR NONRANDOM CHROMOSOME LOSS AND GAIN IN MARINE BIVALVES
( Institute of Malacology , 2022 , Article)Aneuploidy, or presence of an abnormal number of chromosomes, has been commonly observed in marine bivalves. This phenomenon has also been shown to be negatively correlated with growth and survival rates in several species ... -
Anthropogenic related variations in the epibiotic biodiversity and age structure of the “Pearl Oyster” Pinctada radiata within the eulittoral zone of Qatar
( Elsevier , 2016 , Article)Abstract Oyster aggregations provide critical habitat that contain diverse communities, with epibiota and oysters sensitive to environmental disturbance. The monitoring of oysters and associated organisms has become an ... -
