The present study deals with the seasonal variation of temperature, alkalinity and dissolved oxygen in the Sagar lake. Different abiotic and biotic factors were investigated and a diurnal study was made, too. The investigation shows that the surface water values were always higher than the bottom ...
An updated climatology, based on a comprehensive data set (1911???2009) of temperature, salinity and dissolved oxygen, has been produced for the whole Adriatic Sea with the variational inverse method using the DIVA (Data-Interpolating Variational Analysis) software. Climatological maps were produced ...

Otolith Sr/Ca values were also significantly higher at a salinity of 25‰ vs. 15‰, after accounting for differences in dissolved Sr/Ca ratios in the ambient water, with a sensitivity of approximately 1%/salinity (‰). These observations complicate the use of Sr/Ca ratios to determine ...
Different studies have examined selective withdrawal impacts on in-reservoir and downstream temperatures3,4and downstream temperature/in-reservoir dissolved oxygen (DO) tradeoffs5. In particular, the 2D hydrodynamic water quality CE-QUAL-W2 model6has used to examine dam flow control impacts on water ...
This process also removes volatiles and dissolved oxygen. Advantages of the process are reduced chemical damage and a less intense cooked flavour for many products. There are claims that products produced by direct UHT are indistinguishable from pasteurised products. One problem would be the very ...
At any other non-STP temperature, the amount of oxygen can be obtained by multiplying it by 273 / (273 + T). Thus at 20 degrees Celsius, the corresponding value is the following: = 9.37 x (273 / 273 + 20) = 8.73 μmol STP effect on carbon dioxide ...
In that case, increasing flow velocity would effectively increase the supply of oxidant (e.g., free chlorine or dissolved oxygen) to the cathodes2, aiding in development of a differential concentration cell and driving dezincification at the anode. Separation of anodes and cathodes may also ...
First, changes in grain size (sand vs. silt-clay) and provenance in the given sedimentary archive can alter the CIA values46,47. In addition, spatial variability of other environmental variables such as topography and lithology may cause several-unit variations of CIA at a given MAT as ...
At room temperature, titanium (IV) precursors and water are separated since the Ti precursors are dissolved in the nonpolar solvent. Under hydrothermal conditions, water diffuses away from the high-energy water/nonpolar solvent interface to the hydrophilic TiO2 nuclei on ceramic wall, where water ...
