RNA interference showed that PmTyr-4 participated in nacreous-layer formation. The recombinant protein of PmTyr-4 (rPmTyr-4) inhibited the calcium carbonate precipitation rate. Correspondingly, ...

Calcite is the most stable and the least soluble, and, therefore, the form in which calcium carbonate would be expected to precipitate from sea-water. It has been pointed out, however, that when ...

Hard water is the type of water that has high mineral content (in contrast with soft water). Hard water minerals primarily consist of calcium (Ca2+), and ...

Africa is often synonymous with its drylands that cover two-thirds of the continent. Relief is brought through rainfall ...

The objective is to study scale deposition for both carbonate and sulphate scaling systems, and to identify the impact that parameters such as injection water composition and temperature have on the ...

If you do not see those words, you may want to purchase another type of supplement. The two main forms of calcium supplements are calcium carbonate (calcite) and calcium citrate (Citracal). There are ...

These cave deposits formed of calcium carbonate (obtained from Kef Thaleb ... potentially leading to an additional 27cm per year of precipitation. This pattern continued over 8,700 to 4,300 ...

For more than 75 years, high-hazard structures in the U.S., including dams and nuclear power plants, have been engineered to withstand floods resulting from the most unlikely but possible ...
