Assessment of spatial variations of particulate matter (PM10 and PM2.5) in Bahrain identified by air quality index (AQI)

Authors: Jassim M.S., Coskuner G.
The rapid urbanization, industrialization, modernization, and the frequent Middle Eastern dust storms have negatively impacted the ambient air quality in Bahrain. The objective of this study is to identify the most critical atmospheric air pollutants with emphasis on their potential risk to health based on calculated AQI (air quality index) [...]

Relative Growth and Heterochely in the Blue Swimmer Crab Portunus pelagicus (Linnaeus 1758) from the Kingdom of Bahrain

Authors: Zainal K.A.Y.
Portunus pelagicus were obtained from a shallow coastal area in the Kingdom of Bahrain, Arabian Gulf (26 14 909 N and 50 297 121 E) during the years 2004 and 2005 using local fish trap on sandy mud or sand substrates. Different body measurements were carried out including fresh body [...]

Toxicity effect of graphene oxide on growth and photosynthetic pigment of the marine alga Picochlorum sp. during different growth stages

Authors: Hazeem L.J., Bououdina M., Dewailly E., Slomianny C., Barras A., Coffinier Y., Szunerits S., Boukherroub R.
Graphene oxide (GO), a recently discovered material, has been investigated for many applications in various fields. Thus, an immense awareness should be paid on the potential effects of the material on the environment as huge quantities of GO may get to the environment. Aquatic organisms, marine algae as an example, [...]

An integrated approach for soil classification: The Kingdom of Bahrain study case

Authors: Al-Joburi K.
Soil classification is a complicated and difficult process; the level of complexity depends on the extent of the information needed. The objective of this paper is to produce a digital soil map for the Kingdom of Bahrain. The Kingdom does not have such a map at the present time. Borehole [...]

Experimental investigation and computational fluid dynamics analysis of flow and heat transfer for heated plate

Authors: Aksu E., Sarac B., Ayhan T.
This study investigated the characteristics of convective heat transfer and fluid flow for a heated plate surrounded by unheated plates aligned at angles to the flow direction inside a rectangular duct. The plates were arrayed in two main geometries: inline and staggered. Flow deflections within the array of aligned plates [...]

Contribution of citizen science to improve knowledge on marine biodiversity in the Gulf Region

Authors: Castilla A.M., Riera R., Ali Humaid M., Garland T., Jr, Alkuwari A., Muzaffar S., Naser H.A., Al-Mohannadi S., Al-Ajmi D., Chikhi A., Wessels J., Al-Thani M.A.F., Takacs Z., Valdeón A.
Monitoring marine biodiversity is costly and practical solutions have to be implemented to identify species and their preferred habitats, particularly in this era of rapid global change. Citizen science has proven to be effective and with high potential for monitoring efforts, and has been extensively applied to biodiversity. We have [...]

Variability of marine macrofouling assemblages in a marina and a mariculture centre in Bahrain, Arabian Gulf

Authors: Naser H.A.
Marine biofouling has significant environmental and industrial impacts. Biofouling is considered a specific problem for a wide range of coastal and marine industries, including aquaculture, shipping activities and ports. Colonization and growth of biofouling depend on the complex interactions of biological, physical and chemical factors. Anthropogenic disturbances from coastal modification [...]

Fatty acid compositions of raw fish white sardinella (Oom), fish paste (Tareeh), and fish sauce (Mehiawh): Fermented fish products rich in polyunsaturated fatty acids

Authors: Freije A.
Objective: To evaluate the fatty acid contents of raw white sardinella fish and their two fermented products, fish paste (Tareeh) and fish sauce (Mehiawah). Design: A Prospective Experimental Basic Science Study. Setting: University of Bahrain, Bahrain. Method: Four raw Oom fish, four fish paste, and four fish sauce samples were [...]

Hyperspectral image analysis for oil spill detection: A comparative study

Authors: El-Rahman S.A., Zolait A.H.S.
In the last years, oil spill detection by hyperspectral imaging has been transferred from experimental to operational. In this paper, researchers attempted to use and compare four classification approaches for the identification of oil spills. The hyperspectral image classification approaches ‘namely’ are support vector machine (SVM), parallelepiped, minimum distance (MD) [...]

Multiobjective optimization of microalgae (Chlorella sp.) growth in a photobioreactor using Box-Behnken design approach

Authors: Hossain S.M.Z., Alnoaimi A., Razzak S.A., Ezuber H., Al-Bastaki N., Safdar M., Alkaabi S., Hossain M.M.
A parameter optimization approach to maximize the specific growth rate of the Chlorella vulgaris microalgae species, its biomass productivity, and CO2 capture rate was investigated. The Box-Behnken experimental design technique was applied with temperature, nitrogen to phosphorus ratio, and light-dark cycle per day, as the growth controlling parameters. For each [...]
