(
Elsevier
, 2020 , Article)
The Khor Al Adaid embayment of southern Qatar represents a unique shallow-water mixed siliciclastic‑carbonate coastal depositional system that developed in a hyper-arid climatic setting over the past 6000 years. The ...
Pollution Characteristics of Particulate Matter (PM2.5 and PM10) and Constituent Carbonaceous Aerosols in a South Asian Future Megacity
(
MDPI
, 2020 , Article)
The future megacity of Faisalabad is of prime interest when considering environmental
health because of its bulky population and abundant industrial and anthropogenic sources of coarse particles (PM10) and fine airborne ...
Regional stratigraphy, facies distribution, and hydrocarbons potential of the Oligocene strata across the Arabian Plate and Western Iran
(
Springer Verlag
, 2019 , Article)
Major global events during the Oligocene epoch included a climatic change from warm “greenhouse” to a cooler “icehouse” that was accompanied by the onset of Antarctic glaciation. These events led to decline in water ...
Distribution and environmental geochemical indices of mercury in tar contaminated beaches along the coast of Qatar
(
Elsevier
, 2022 , Article)
The current study aimed to gauge total mercury (THg) concentration and the environmental geochemical indices in tarmat contaminated sediments and test their presence in targeted coastal species. Layers of hard asphalt-like ...
Determination of total flavonoid content by aluminum chloride assay: A critical evaluation
(
Elsevier
, 2021 , Article)
Flavonoids are important natural bioactive compounds. Quantitation of total flavonoid content (TFC) is widely performed using the aluminum chloride colorimetric assay against a flavonoid standard assuming equal responses ...
Role of shamal and easterly winds on the wave characteristics off Qatar, central Arabian Gulf
(
Elsevier
, 2021 , Article)
Waves in the Arabian Gulf (Gulf) are dominated by shamal winds during winter and early summer. Although wave characteristics in the Gulf are broadly studied, features associated with various wind systems are not explicitly ...
