Sentences with phrase «at the high concentrations achieved»

despite its controversy in mainstream medicine that antioxidants counteract chemotherapy, at the high concentrations achieved intravenously, vitamin C acts as a prooxidant and is toxic to tumor cells.

Not exact matches

1 A review of the literature has shown that short - term ingestion of foods containing a small amount of MCTs suppresses the increase in blood lactate concentration and the rate of perceived exertion (RPE) during moderate - intensity exercise; whilst extending the duration of subsequent high - intensity exercise, at levels higher than those achieved by ingestion of LCT - containing foods.2

«commercially compressed CO [gas must be] used and the following precautions... taken: (1) personnel using CO must be instructed thoroughly in its use and must understand its hazards and limitations; (2) the CO chamber must be of the highest quality construction and should allow for separation of individual animals; (3) the CO source and chamber must be located in a well - ventilated environment, preferably out of doors; (4) the chamber must be well lit and have view ports that allow personnel direct observation of animals; (5) the CO flow rate should be adequate to rapidly achieve a uniform CO concentration of at least 6 % after animals are placed in the chamber...; and (6) if the chamber is inside a room, CO monitors must be placed in the room to warn personnel of hazardous concentrations.

To the best of my knowledge, increased atmospheric CO2 does not appreciably reduce the flux from below of CO2 - absorbable infrared into the stratosphere when a new steady state is achieved at the higher CO2 concentration.

Carbon dioxide removal addresses the root cause of climate change — high concentrations of the greenhouse gas in the atmosphere — and generally have well - understood benefits and risks, but current technologies would take decades to achieve moderate results and be cost - prohibitive at scales large enough to have a sizeable impact.

In order to have a reasonable chance of achieving the goal, the concentration of greenhouse gases would probably need to be stabilised at a level no higher than 450 ppm CO2 - eq.

Stabilizing CO2 equivalent concentrations at 450 ppm would only result in a 50 % likelihood of limiting global warming to 2 °C, and that it would be necessary to achieve stabilisation below 400 ppm to give a relatively high certainty of not exceeding 2 °C.

At the same time, the larger firm size required to achieve minimum efficient scale means that higher industrial concentrations may be necessary in order to achieve productive efficiency.
