IONIC AND WATER BALANCE OF PLANARIANS

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Planarians

World Health Organization launched the most ambitious and expensive international programme in history to eradicate smallpox once and for all. After many vicissitudes and no little heroism on the part of the workers sent into remote and hostile territories, the objective was accomplished amidst much jubilation. September of 1977 saw the last recorded case of naturally transmitted smallpox on th...

Water-soluble ionic benzoporphyrins.

Novel ionic water-soluble tetrabenzoporphyrins have been successfully synthesized via a cascade reaction based on the Heck reaction. The UV-Vis spectra of these porphyrins displayed red-shifted and broadened Soret bands, and significantly enhanced Q bands. These porphyrins are highly water soluble.
