Upon exposure to water and oxygen, these minerals oxidize to form acid-, iron- and sulfate-rich drainage.
Afterward, she washed and conditioned our hair with a DevaCurl sulfate-free shampoo and conditioner.
Observations from orbit have identified clay and sulfate minerals in the lower layers, indicating a wet history.
ENGADGET: NASA's Curiosity rover receives long-distance OTA update, 'brain transplant' on Mars
In any case, if the sulfate hypothesis is right, then your prediction of warming might end up being wrong.
The rock that Curiosity found, on the other hand, has calcium sulfate and seems to have been in water with a neutral pH.
Although sulfate particles may have had the short-term effect of cooling temperatures, in the long run, pumping CO2 into the atmosphere spells trouble.
Researchers are also testing a number of other solutions that may help relieve the symptoms of interstitial cystitis, including hyaluronan, chondroitin sulfate and oxybutynin.
For users who might crush the tablet to snort, the formulation contains sodium lauryl sulfate (sodium dodecyl sulfate, or SDS, to my laboratory brethren).
FORBES: Acura Pharmaceuticals Launches Meth-Resistant Pseudoephedrine, Nexafed
Studies have shown that copper sulfate, pyrethrins, and rotenone all can be detected on plants after harvest for copper sulfate and rotenone, those levels exceeded safe limits.
FORBES: Bittman of the 'New York Times': Always Out To Lunch
This liberates hydrogen ions for the acidity, turns insoluble sulfide into very soluble sulfate, and creates rust from reduced iron, a fascinating, if annoying, chemical process.
He doesn't dispute the fact that Opportunity found sulfate salts.
Dr. SQUYRES: We found an enormous quantity of sulfur in this rock, too much to explain by any other mechanism, we believe, than this rock being full of sulfate salts.
Mr. TOM McCOLLOM (Geochemist, University of Colorado): The sulfate salts that are in there come from reaction of the rock with sulfuric acid rather than from evaporation of a fluid.
Although other theories remain about why this past decade was cooler than those previous, scientists seem to be converging around this idea that sulfate particles, which reflect the sun, are the culprits.
Finally, in a third set of simulations, they doubled the CO2 in the atmosphere, but added a layer of sulfate aerosols to the stratosphere, which would deflect about two per cent of incoming sunlight from the earth.
The medications typically in short supply are generally low cost drugs such as morphine sulfate, zofran, compazine, reglan, ativan and valium.. The shortages often involve injectable drugs which are more technically difficult to manufacture than oral medications.
And in fact those same sulfate particles are a primary ingredient in acid rain, so loading the atmosphere with them is probably not a good idea either (although geoengineering proponents have suggested doing exactly that to help cool the climate).
Global health commodities obey the same laws of economics as any other commodities: shaping markets to bring supply and demand into alignment will yield significant improvements in the delivery and availability of key products such as oxytocin and magnesium sulfate.
FORBES: Building a Thriving Marketplace for Life-Saving Commodities
The FDA's warning letters notified the companies they may be subject to legal action if they do not stop manufacturing and distributing "prescription unapproved products" that include high-concentrate morphine sulfate oral solutions and immediate-release tablets containing morphine sulfate, hydromorphone or oxycodone.
