Stable carbon isotope ratios in marine aerosol collected over the Southern Indian Ocean revealed δ13C values ranging from -20.0‰ to -28.2‰. The isotope ratios exhibited a strong correlation with the fractional organic matter (OM) enrichment in sea spray aerosol. The base-level isotope ratio of -20.0‰ is characteristic of an aged Dissolved Organic Matter (DOM) pool contributing a relatively homo...

A scheme for large-scale dew collection as a source of fresh water supply is outlined in the present paper. The scheme envisages bringing cold seawater (5C) from about 500 meters depth and about 5 km from the shore, in four, 1.22 m diameter plastic pipes. It then passes through an onshore heat exchanger field with an area of 1.29 X 10 m (1.39 X 10 ft) where it condenses 643 m of dew over the 24...

The sterilization effect of a combination treatment with alkaline electrolyzed water (AlEW) and strong acidic electrolyzed water (StAEW) on fresh chicken breasts and beef liver was evaluated. Samples (1, 5, and 10 g) were inoculated with Salmonella Enteritidis NBRC3313, Escherichia coli ATCC 10798, Staphylococcus aureus FDA209P, and S. aureus C-29 [staphylococcal enterotoxin A (SEA) productive ...

objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...

Minute amounts of photosynthesis in marine plants can be accurately measured by adding a little phenolphthalein to the sea water, and observing changes in the color of the indicator. In the case of fresh water aquatics bicarbonates are added. By this method it is found that Ulva which has been kept in the dark begins photosynthesis as soon as it is exposed to sunlight and that the rate steadily...

Common eiders (Somateria mollissima) were fed added Se (as L-selenomethionine) in concentrations increasing from 10 to 80 ppm in a pilot study (Study 1) or 20 (low exposure) and up to 60 (high exposure) ppm Se in Study 2. Body weights of Study 1 ducks and high-exposure ducks in Study 2 declined rapidly. Mean concentrations of Se in blood reached 32.4 ppm wet weight in Study 1 and 17.5 ppm wet w...

Muscle and other tissues of marine invertebrates are very dilute with respect to inorganic ions, but are nevertheless in osmotic equilibrium with the blood, in which ionic concentrations are nearly the same as in sea water (1). It has been postulated, therefore, that these tissues contain relatively high concentrations of small organic molecules (l), and it is of interest in this connection tha...

abstract experiment was conducted for 8 weeks to determine the reaction (astacus leptodactylus) to interaction energy and salinity. diets containing 3 levels of energy (300,370 and 450 kcal/100g) with a constant protein content of 30% and 2 levels of salinity (fresh water and brackish water (12 ppt) were formulated. tank content 110 liter, each filled with 80 liter water. 5 a.leptodactylus (ave...
