The growth chamber is heated to 1300-1600 °C with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. Carbon atoms precipitate on a small diamond seed crystal, and a synthetic diamond begins to grow. The lab-grown crystal is then cut and polished by a diamond cutter.

The only absolute contraindication for mechanical ventilation is if it is against the patient's stated wishes for artificial life-sustaining measures. ... What this means is that the ventilator applies a continuous high pressure (P high) for a set amount of time (T high) and then releases that pressure, usually going back to zero (P low) for a ...

According to Mayo Clinic, current evidence suggests that it's not the artificial sweeteners in diet soda that could affect blood pressure, but rather other ingredients. Diet soda contains sodium, and some salt-sensitive individuals may experience blood pressure increases when they consume a diet high in sodium, according to a July …

The other studies revealed possible links between artificial sweetener use and high blood pressure, diabetes, and heart disease. The reasons behind these trends aren't fully understood. Some researchers believe sugar substitutes may leave the brain unsatisfied, leading to unhealthy cravings and overeating. The study appeared in the July …

Colloid osmotic pressure of artificial tears J Ocul Pharmacol. Winter 1985;1(4):327-36. doi: 10.1089/jop.1985.1.327. Authors F J Holly 1 ... We believe that the favorable patient acceptance of HypoTears is more likely due to this unusually high oncotic pressure than to its hypoosmolality. Such an artificial tear formulation should be effective ...
