The cumulative impacts of reclamation and dredging on the marine ecology and land-use in the Kingdom of Bahrain.

This article assesses the ecological and economic impacts of land reclamation and dredging through consulting recent environmental impact assessment reports. Geographic features of Bahrain during 1963-2008 are produced using Geographical Information System. Extensive but inexpensive shallow coastal areas and tidal flats have been reclaimed particularly from 1997 to 2007 at a high rate of 21 km(2)/year.

Comparison of cellular response to anorganic bone matrix/cell binding peptide and allogenic cranial bone after sinus augmentation in rhesus monkeys.

This study compared cellular responses of maxillary sinuses after augmentation with anorganic bovine-derived hydroxyapatite matrix linked to the cell binding polypeptide P-15 (ABM/P-15) or PepGen P-15 and allogenic freeze-dried cranial bone slabs. Five adult Macaque fascicularis monkeys were used. On one side, the floor of the sinus was augmented with ABM/P-15, while the other side was augmented with 2 cranial bone slabs.

Temporal and spatial variations of the quality of ambient air in the Kingdom of Bahrain during 2007.

The main objective of the present investigation is to study the temporal and spatial variations of the quality of ambient air in the Kingdom of Bahrain. The non-parametric Kruskal-Wallis (KW) test showed significant spatial variations and interactions of spatial-temporal among five mobile monitoring stations for 11 air pollutants. The Mann Whitney (MW) test demonstrated the seasonality of spring over winter for the PM(10), PM(2.

Trends in water quality of some wells in Saudi Arabia, 1984-1989.

A survey of the quality of 4255 well samples collected from 1062 wells in the period 1984 through 1988, 388 samples collected in 1989, and 319 tank water samples distributed to houses, has been conducted throughout the Kingdom of Saudi Arabia. Sampling included seven regions in Saudi Arabia and analyzed for total dissolved salts, nitrate, nitrite, ammonium and faecal coliforms. The data generally showed a progressive improvement in the quality of well samples during the period under investigation.

Effects of organic amendments and irrigation waters on the physical and chemical properties of two calcareous soils in Bahrain.

The present investigation studies the effects of cow and chicken manure and sewage sludge at different rates of addition and with two irrigation waters of different salinities on two major calcareous soils in Bahrain. The aim was to quantify potential improvements in soil quality, the accumulation of trace metals, and quality of leachates.From the pot experiments it was found that soil waterholding capacity did not change significantly after addition of organic amendments, except in the case of sewage sludge.
