Experimental investigation and CFD modeling to assess the performance of solar air humidifier

Authors: Al-Abbasi O., Sarac B., Ayhan T.

The humidification chamber is a vital component of the humidification-dehumidification cycle that plays an essential role in determining the effectiveness of this system. In this study, the combined effect of heating and humidifying processes in the plate type humidification chamber, the so-called solar air humidifier is investigated experimentally and using [...]

Quantifying exposure levels of coastal facilities to oil spills in Bahrain, Arabian Gulf

Authors: Marzooq H., Naser H.A., Elkanzi E.M.

The Arabian Gulf is considered as a hub for global oil industry. Thus the Arabian Gulf marine environment is under permanent threat from oil spills due to oil exploitation, production, and transportation. Oil pollution poses adverse effects on marine environment, society, and economy. Oil spill incidents that occurred in Bahrain [...]

Recent Advances in Iron Oxide Nanoparticles (IONPs): Synthesis and Surface Modification for Biomedical Applications

Authors: Noqta O.A., Aziz A.A., Usman I.A., Bououdina M.

In recent years, extensive researches were devoted to iron oxide nanoparticles (IONPs), including magnetite (Fe3O4) and maghemite (γ-Fe2O3), due to their low toxicity and cost, in addition to their unique physicochemical and magnetic properties. In this review, we present a brief introduction on IONPs in terms of classification and properties. [...]

Toxicity effect of silver nanoparticles on photosynthetic pigment content, growth, ROS production and ultrastructural changes of microalgae chlorella vulgaris

Authors: Hazeem L.J., Kuku G., Dewailly E., Slomianny C., Barras A., Hamdi A., Boukherroub R., Culha M., Bououdina M.

Silver nanoparticles (Ag NPs) exhibit antibacterial activity and are extensively used in numerous applications. The aim of this study was to examine the toxic effect of Ag NPs on the marine microalga, Chlorella vulgaris. The microalgae, at the exponential growth phase, were treated with different concentrations of Ag NPs (50 [...]

Temperature Dependence of the Heart Rates in the Blue Swimming Crab Portunus segnis (Forskal, 1775)

Authors: Zainal K., Noorani A.

Portunus segnis (Forskal, 1775) has been referred to as Portunus pelagicus for very long time until Portunus species complex have been recognized based on their molecular distinction (Lai in Raffles Bull Zool 58(2):199–237, 2010). P. segnis are native species in the Arabian Gulf. Inter-moult stage adults were caught during February–November [...]

Is There Enough Evidence for Osteosarcopenic Obesity as a Distinct Entity? A Critical Literature Review

Authors: Bauer J.M., Cruz-Jentoft A.J., Fielding R.A., Kanis J.A., Reginster J.-Y., Bruyère O., Cesari M., Chapurlat R., Al-Daghri N., Dennison E., Kaufman J.-M., Landi F., Laslop A., Locquet M., Maggi S., McCloskey E., Perna S., Rizzoli R., Rolland Y., Rondanelli M., Szulc P., Vellas B., Vlaskovska M., Cooper C.

The co-existence of impaired bone health (osteopenia/osteoporosis), reduced muscle mass and strength (sarcopenia), and increased adiposity (obesity) in middle-aged and older people has been identified in recent studies, leading to a proposal for the existence of “osteosarcopenic obesity” as a distinct entity. Evidence for the pathophysiological overlap of these conditions [...]

Reverse osmosis (RO) membrane desalination driven by wind and solar photovoltaic (PV) energy: State of the art and challenges for large-scale implementation

Authors: Mito M.T., Ma X., Albuflasa H., Davies P.A.

The use of Reverse Osmosis (RO) desalination has grown considerably in response to water scarcity. Despite steady improvements in efficiency, RO desalination remains an energy-intensive process. Numerous studies focussed on using mature Renewable Energy Sources (RES), such as wind and solar photovoltaic (PV) energy, to drive RO plants on a [...]

Cost contingency modelling for construction projects: Insight from the literature

Authors: Islam M.S., Nepal M.P., Alam M.S., Arifuzzaman M.

A review of cost contingency modelling in construction projects is presented to find the application areas and limitations of the existing models to pinpoint the further research gap. Three broader approaches of contingency modelling are found: 1) a data-intensive contingency prediction model without risk analysis, (2) contingency estimation following a [...]

Optimization of Precursor Concentration for the Fabrication of V2O5 Nanorods and their MSM Photodetector on Silicon Substrate

Authors: Abd-Alghafour N.M., Mohammed S.M., Ahmed N.M., Hassan Z., Almessiere M.A., Afzal N., Bououdina M.

This paper presents the effects of precursor concentration on different properties of the V2O5 nanorods (NRs) grown by using spray pyrolysis technique. The V2O5 NRs with different precursor concentrations of VCl3 such as 0.05 M, 0.10 M, 0.15 M, and 0.20 M were prepared on the silicon (Si) substrates. The structural characteristics of NRs [...]
