In this work, two field campaigns were performed in July 2008 (wet season) and March 2009 (dry season) to produce original data on the concentration, partition and distribution of mercury and butyltin compounds along the tropical Bach Dang Estuary located in North Vietnam (Haiphong, Red River Delta). The results demonstrate that mercury and butyltin speciation in the surface waters of this type...

INTRODUCTION: Cystic fibrosis (CF) patients have abnormally viscid bronchial secretions that cause airway obstruction, inflammation, and infection that leads to lung damage. To enhance airway clearance and reduce airway obstruction, daily bronchopulmonary hygiene therapy is considered essential. OBJECTIVE: Compare the effectiveness of and patient preferences regarding 3 airway clearance methods...

Between them Dorothy McLaren and Valerie Fildes have pioneered the study of English wet-nursing. In her work on the parish of Chesham during the late sixteenth century, McLaren drew attention to the way in which prolonged lactation reduced fertility. Believing that most mothers understood this, she suggested that some women might have become wet-nurses in order to limit family size.' Fildes, ca...

Critical loads (CLs) define maximum atmospheric deposition levels apparently preventative of ecosystem harm. We present first nitrogen CLs for northwestern North America's maritime forests. Using multiple linear regression, we related epiphytic-macrolichen community composition to: 1) wet deposition from the National Atmospheric Deposition Program, 2) wet, dry, and total N deposition from the C...

15 Numerical and theoretical studies have shown that mesoscale gradients in land surface properties can induce circulations in the atmosphere. This study provides the first well-resolved observations of such flows induced by soil moisture from recent rainfall, and is based on aircraft data in the Sahel. Satellite imagery was used to identify fine scale soil moisture features within a wet zone s...

in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

Mercury (Hg) in autumn litterfall from predominately deciduous forests was measured in 3 years of samples from 23 Mercury Deposition Network sites in 15 states across the eastern USA. Annual litterfall Hg dry deposition was significantly higher (median 12.3 micrograms per square meter (μg/m(2)), range 3.5-23.4 μg/m(2)) than annual Hg wet deposition (median 9.6 μg/m(2), range 4.4-19.7 μg/m(2)). ...

Ammonia was directly synthesised from wet air at 400 °C at atmospheric pressure. A new perovskite Sm(0.6)Ba(0.4)Fe(0.8)Cu(0.2)O(3-δ) was used as the electrocatalyst for electrochemical synthesis of ammonia. Ammonia formation rates of 9.19 × 10(-7) mol s(-1) m(-2) and 1.53 × 10(-6) mol s(-1) m(-2) were obtained at 400 °C when wet air and wet N2 were introduced into a simple single chamber reacto...
