Groundwater chemistry of small tropical islands is influenced by many factors, such as recharge, weathering and seawater intrusion, among others, which interact with each other in a very complex way. In this work, multivariate statistical analysis was used to evaluate the factors controlling the groundwater chemistry of Kapas Island (Malaysia). Principal component analysis (PCA) was applied to ...

introduction: reverse osmosis (ro) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. the aim of this research was the performance study of reverse osmosis plants for water desalination in bandar-lengeh, iran. materials and method...

Bacteriovorax were quantified in US Atlantic, Gulf, and Pacific seawater to determine baseline levels of these predatory bacteria and possible seasonal fluctuations in levels. Surface seawater was analyzed monthly for 1 year from Kailua-Kona, Hawaii; the Gulf Coast of Alabama; and four sites along the Delaware Bay. Screening for Bacteriovorax was performed on lawns of V. parahaemolyticus host c...

High-throughput cultivation studies have been successful at bringing numerous important marine bacterioplankton lineages into culture, yet these frequently utilize natural seawater media that can hamper portability, reproducibility, and downstream characterization efforts. Here we report the results of seven experiments with a set of newly developed artificial seawater media and evaluation of c...

Aim: Seawater drowning induced-acute lung injury (ALI) is a serious clinical condition characterized by refractory hypoxemia, enhanced alveolar-capillary permeability, hemorrhage, and uncontrolled overwhelming inflammatory responses. Hydrogen sulfide (H2S) is an endogenous gaseous mediator that plays an important role in the physiological and pathophysiological conditions, especially in some in...

Very low concentrations (pg mL(-1) or sub-pg mL(-1) level) along with the high salinity are the main problems in determining trace metal contents in seawater. This problem is mainly considered for investigations of naturally occurring YLOID (Y and Lanthanides) and Zr and Hf in order to provide precise and accurate results. The inductively coupled plasma mass spectrometry (ICP-MS), both in high ...

Deep seawater is a valuable renewable resource. Due to its outstanding characteristics (i.e., clean, nutrient-rich and cold), deep seawater has been utilized in various subjects, such as mariculture, agriculture, food and beverage, pharmaceutical, medical, and renewable energy. As a result, deep seawater utilization cannot be separated from membrane technologies. Reverse osmosis has become the ...

Perth will run out of available sustainable natural water resources by 2015 if nothing is done to slow usage rates, according to a Western Australian study [1]. Alternative water technology options need to be considered for the long-term guaranteed supply of water for agricultural, commercial, domestic and industrial purposes. Seawater is an alternative source of water for human consumption, be...
